Revision	Date	Author	Comments
1.4	09-Aug-2016	kre	Revert previous - which itself (incorrectly) reverted the previous changes, breaking the build.
1.3	09-Aug-2016	christos	More htree writing support (Hrishikesh Goyal GSoC 2016)
1.2	03-Jun-2016	joerg	Install new header and fix rump to include the corresponding source as well.
1.1	12-Jun-1998	cgd	branches: 1.1.198; 1.1.218; Rework the way kernel include files are installed. In the new method, as with user-land programs, include files are installed by each directory in the tree that has includes to install. (This allows more flexibility as to what gets installed, makes 'partial installs' easier, and gives us more options as to which machines' includes get installed at any given time.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_ still supported, though at least one bug in the 'symlinks' case is fixed by this change. Include files can't be build before installation, so directories that have includes as targets (e.g. dev/pci) have to move those targets into a different Makefile.
1.1.218.1	09-Jul-2016	skrll	Sync with HEAD
1.1.198.1	03-Dec-2017	jdolecek	update from HEAD
1.53	04-May-2025	rillig	ext2fs.h: avoid adjacent commas in unsupported features A question mark still stands out enough to be noticeable. Noticed by lint.
1.52	27-Aug-2023	christos	branches: 1.52.6; - fix cgload/cgsave inconsistencies - add a constant for the rev 0 group descriptor size
1.51	26-Aug-2023	riastradh	ext2fs: Nix trailing whitespace.
1.50	26-Aug-2023	riastradh	ext2fs.h: Restore e2fs_cgload/cgsave for libsa and userland use. Stop-gap until they can be taught to handle the new version that was moved to ext2fs_vfsops.c, presumably.
1.49	25-Aug-2023	christos	Support INCOMPAT_64BIT on ext4 (Vladimir 'phcoder' Serbinenko)
1.48	20-Aug-2016	jdolecek	add support for GDT_CSUM AKA uninit_bg feature
1.47	15-Aug-2016	jdolecek	EXT2F_INCOMPAT_FLEX_BG feature actually doesn't require any explicit code changes, all magic is done by setting the block offsets appropriately in group descriptors by newfs; add it to the list of supported INCOMPAT flags
1.46	15-Aug-2016	jdolecek	bump link limit to 65000 for files, and add support for EXT2F_ROCOMPAT_DIR_NLINK to make link count unlimited for directories
1.45	14-Aug-2016	jdolecek	switch ext2fs_htree_has_idx() over to EXT2F_HAS_COMPAT_FEATURE() and remove EXT2F_HAS_COMPAT_FEATURE() - this also fixes it for BE machines, as EXT2F_HAS_COMPAT_FEATURE() did extra byte swap; also remove XXX comment about IN_E3INDEX
1.44	14-Aug-2016	jdolecek	add EXT2F_HAS_ROCOMPAT_FEATURE() macro, and change the current EXT2F_HAS_{COMPAT\|INCOMPAT}_FEATURE() to take fs as first parameter
1.43	12-Aug-2016	macallan	sprinkle ()s in macros with comparisons, shuts up compiler warnings
1.42	12-Aug-2016	jdolecek	add support for extended attributes in ext2fs for ext3/ext4; read-only for now
1.41	05-Aug-2016	jdolecek	add defines for the missing ext4 feature flags
1.40	04-Aug-2016	jdolecek	rename struct ext2fs_dinode attribute e2di_dacl to correct e2di_size_high; even Linux ext2 filesystem code actually uses it unconditionally this way and ext4 code finally also calls it that way in their struct definition too; if there was any trace of this for other purpose it's long gone
1.39	03-Aug-2016	jdolecek	support arbitrary ext3/ext4 inode size, add all the new ext4 fields ext2fs_dinode, and add support for loading the extra inode data
1.38	24-Jun-2016	christos	branches: 1.38.2; GSoC 2016 (Hrishikesh Goyal): Htree index support from FreeBSD
1.37	03-Jun-2016	christos	Add ext4 extent support from GSoC 2016 (Hrishikesh Goyal), from the FreeBSD ext2 code.
1.36	23-Jun-2013	dholland	branches: 1.36.10; Stick ffs_, ext2_, chfs_, filecore_, cd9660_, or mfs_ in front of the following symbols so as to disambiguate fully. (Christos already did the lfs ones.) lblkno lblktosize lfragtosize numfrags blkroundup fragroundup
1.35	23-Jun-2013	dholland	fsbtodb() -> FFS_FSBTODB(), EXT2_FSBTODB(), or MFS_FSBTODB() dbtofsb() -> FFS_DBTOFSB() or EXT2_DBTOFSB() (Christos already did the lfs ones a few days back)
1.34	19-Jun-2013	dholland	Rename ambiguous macros: MAXDIRSIZE -> UFS_MAXDIRSIZE or LFS_MAXDIRSIZE NINDIR -> FFS_NINDIR, EXT2_NINDIR, LFS_NINDIR, or MFS_NINDIR INOPB -> FFS_INOPB, LFS_INOPB INOPF -> FFS_INOPF, LFS_INOPF blksize -> ffs_blksize, ext2_blksize, or lfs_blksize sblksize -> ffs_blksize These are not the only ambiguously defined filesystem macros, of course, there's a pile more. I may not have found all the ambiguous definitions of blksize(), too, as there are a lot of other things called 'blksize' in the system.
1.33	21-Nov-2012	jakllsch	Write support for the Ext4 Read-only Compatible Feature "huge_file". Primarily, this feature extends the inode block count field to 48 bits. Additionally, this feature allows this field to be represented in file system block size units rather than DEV_BSIZE units.
1.32	21-Nov-2012	jakllsch	Add various newer Ext2 superblock feature bits and inode flag bits.
1.31	19-Nov-2012	jakllsch	snprintb EXT2F_ROCOMPAT_SPARSESUPER as such.
1.30	01-Sep-2012	christos	branches: 1.30.2; really print the incompatible bits.
1.29	27-Nov-2009	tsutsui	branches: 1.29.12; Add definitions for more reserved inodes.
1.28	19-Oct-2009	bouyer	Remove closes 3 & 4 from my licence. Lots of thanks to Soren Jacobsen for the booring work !
1.27	12-Sep-2009	tsutsui	Migrate from u_intNN_t to uintNN_t.
1.26	25-Dec-2007	perry	branches: 1.26.10; Convert many of the uses of __attribute__ to equivalent __packed, __unused and __dead macros from cdefs.h
1.25	17-Nov-2007	tsutsui	branches: 1.25.2; 1.25.6; Misc cosmetics.
1.24	15-Nov-2007	tsutsui	Add some definitions for resizefs features.
1.23	13-Nov-2007	tsutsui	- add some more constant definitions - add some comments - typo and some cosmetics
1.22	16-Feb-2006	perry	branches: 1.22.38; 1.22.40; 1.22.44; 1.22.46; Change "inline" back to "__inline" in .h files -- C99 is still too new, and some apps compile things in C89 mode. C89 keywords stay. As per core@.
1.21	29-Jan-2006	dsl	branches: 1.21.2; 1.21.4; Make almost everything #include <sys/bswap.h> instead of <machine/bswap.h> The bswap.h and endian.h files are all rather incestuous, but I want to get the constant folding stuff into one place - sys/bswap.h
1.20	24-Dec-2005	perry	branches: 1.20.2; Remove leading __ from __(const\|inline\|signed\|volatile) -- it is obsolete.
1.19	11-Dec-2005	christos	merge ktrace-lwp.
1.18	30-Aug-2005	xtraeme	* Remove __P() * Use ANSI function declarations on ext2fs and mfs
1.17	26-Feb-2005	perry	branches: 1.17.4; nuke trailing whitespace
1.16	09-Feb-2005	ws	Add support for large files (>2GB). Like Linux, automagically convert old filesystem to use this, if they are already at revision 1. For revision 0, just punt (unlike Linux; makes me a bit too nervous.) There should be an option to fsck_ext2fs to upgrade revision 0 to revision 1. Reviewd by Manuel (bouyer@).
1.15	22-Mar-2004	bouyer	branches: 1.15.8; 1.15.10; Fix disclaimer in my copyright. Pointed out by Thomas Klausner.
1.14	05-Oct-2003	bouyer	Remove references to University of California from my copyright notices.
1.13	07-Aug-2003	agc	Move UCB-licensed code from 4-clause to 3-clause licence. Patches provided by Joel Baker in PR 22364, verified by myself.
1.12	24-Jan-2003	fvdl	branches: 1.12.2; Bump daddr_t to 64 bits. Replace it with int32_t in all places where it was used on-disk, so that on-disk formats remain the same. Remove ufs_daddr_t and ufs_lbn_t for the time being.
1.11	01-Dec-2002	matt	Add multiple inclusion protection for headers. Fix mismatched variable declarations (missing const's) as needed.
1.10	28-Jan-2000	bouyer	branches: 1.10.6; Correct (minor) bogons in filetype option support, and add support for sparse_super option
1.9	26-Jan-2000	bouyer	First cut at ext2fs rev 1 support (as of mke2fs 1.18): supports the filetype option read/write and the sparse option read-only.
1.8	17-Feb-1999	bouyer	branches: 1.8.2; 1.8.8; 1.8.14; Some new fields in the ext2fs superblock, from Tim Shepard. While I'm there, reformat this file a bit.
1.7	15-Jan-1999	bouyer	Move the bswap functions from libutil to libc (this bups the minor of libc and the major of libutil). For little-endian architectures merge the bnswap() assembly versions with nto* and hton* using symbols aliasing. Use symbol renaming for the bswap function in this case to avoid namespace pollution. Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian machines, common code for inline macros go in machine/byte_swap.h Sync libkern with libc. Adjust #include in kernel sources for machine/bswap.h.
1.6	30-Sep-1998	bouyer	Not time to #include <machine/bswap.h>m, it will come with the move of bswap*() from libutil to libc. Sorry !
1.5	29-Sep-1998	bouyer	#include opt_uvm.h only if _KENREL and !_LKM Make ext2fs_init() call ufs_init(). it was doing the init by itself, testing for extern done != 0. This bug was hidden by the fact that ext2fs_init() is called before ffs_init().
1.4	09-Aug-1998	perry	bzero->memset, bcopy->memcpy, bcmp->memcmp
1.3	01-Mar-1998	fvdl	Merge with Lite2 + local changes
1.2	09-Oct-1997	bouyer	Add byte-swapping functions (bswap16, bswap32, bswap64) to libkern. Only assembly version for i386 bswap16 and bswap32 for now (bswap64 uses bswap32). Contribution of assembly versions of these are welcome. Add byte-swapping of ext2fs metadata for big-endian systems. Tested on i386 and sparc.
1.1	11-Jun-1997	bouyer	branches: 1.1.4; The ext2fs layer, based on the ffs/ufs one. Uses a few functions from sys/ufs/ufs/
1.1.4.1	14-Oct-1997	thorpej	Update marc-pcmcia branch from trunk.
1.8.14.1	21-Dec-1999	wrstuden	Initial commit of recent changes to make DEV_BSIZE go away. Runs on i386, needs work on other arch's. Main kernel routines should be fine, but a number of the stand programs need help. cd, fd, ccd, wd, and sd have been updated. sd has been tested with non-512 byte block devices. vnd, raidframe, and lfs need work. Non 2**n block support is automatic for LKM's and conditional for kernels on "options NON_PO2_BLOCKS".
1.8.8.1	20-Nov-2000	bouyer	Update thorpej_scsipi to -current as of a month ago
1.8.2.1	01-Feb-2000	he	Apply patch (requested by bouyer): Add support for ext2fs revision 1, with read-only support for the 'sparse_super' and 'filetype' options. Should fix PR#9088.

1.56	26-Aug-2023	christos	fix incorrect test
1.55	26-Aug-2023	christos	Fix metadata_cksum (Vladimir Serbinenko) Current code always assumes that CG uses crc16. Yet when metadata_cksum is enabled then it uses truncated crc32c. This patch doesn't implement full metadata_cksum, just allows volumes with metadata_cksum to be mounted read-only.
1.54	26-Aug-2023	riastradh	ext2fs: Nix trailing whitespace.
1.53	25-Aug-2023	christos	Support INCOMPAT_64BIT on ext4 (Vladimir 'phcoder' Serbinenko)
1.52	28-May-2017	hannken	Change ext2fs to use vcache_new like we did for ffs: - Change ext2fs_valloc to return an inode number. - Make ext2fs_makeinode private to ext2fs_vnops.c and pass vattr instead of mode.
1.51	20-Aug-2016	jdolecek	modify the comment to note code needs to brele() to have a shot on actually working

1.44	20-Dec-2012	hannken	Change bread() and breadn() to never return a buffer on error and modify all callers to not brelse() on error. Welcome to 6.99.16 PR kern/46282 (6.0_BETA crash: msdosfs_bmap -> pcbmap -> bread -> bio_doread)

1.39	07-May-2009	elad	Introduce several actions/requests for authorizing file-system related operations, specifically quota and block allocation from reserved space. Modify ufs_quotactl() to accomodate passing "mp" earlier by vfs_busy()ing it a little bit higher. Mailing list reference: http://mail-index.netbsd.org/tech-kern/2009/04/26/msg004936.html Note that the umapfs request mentioned in this thread was NOT added as there is still on-going discussion regarding the proper implementation.

Remove the "lwp " arguments that were added to VFS_ROOT(), VFS_VGET(), and VFS_FHTOVP(); all they did was pass it to vget() (which, as noted above, didn't use it).

1.17	28-Jun-2003	darrenr	Pass lwp pointers throughtout the kernel, as required, so that the lwpid can be inserted into ktrace records.

1.43	05-Sep-2020	riastradh	Round of uvm.h cleanup. The poorly named uvm.h is generally supposed to be for uvm-internal users only. - Narrow it to files that actually need it -- mostly files that need to query whether curlwp is the pagedaemon, which should maybe be exposed by an external header. - Use uvm_extern.h where feasible and uvm_*.h for things not exposed by it. We should split up uvm_extern.h but this will serve for now to reduce the uvm.h dependencies. - Use uvm_stat.h and #ifdef UVMHIST uvm.h for files that use UVMHIST(ubchist), since ubchist is declared in uvm.h but the reference evaporates if UVMHIST is not defined, so we reduce header file dependencies. - Make uvm_device.h and uvm_swap.h independently includable while here. ok chs@
1.42	03-Sep-2018	riastradh	Rename min/max -> uimin/uimax for better honesty. These functions are defined on unsigned int. The generic name min/max should not silently truncate to 32 bits on 64-bit systems. This is purely a name change -- no functional change intended. HOWEVER! Some subsystems have #define min(a, b) ((a) < (b) ? (a) : (b)) #define max(a, b) ((a) > (b) ? (a) : (b)) even though our standard name for that is MIN/MAX. Although these may invite multiple evaluation bugs, these do _not_ cause integer truncation. To avoid `fixing' these cases, I first changed the name in libkern, and then compile-tested every file where min/max occurred in order to confirm that it failed -- and thus confirm that nothing shadowed min/max -- before changing it. I have left a handful of bootloaders that are too annoying to compile-test, and some dead code: cobalt ews4800mips hp300 hppa ia64 luna68k vax acorn32/if_ie.c (not included in any kernels) macppc/if_gm.c (superseded by gem(4)) It should be easy to fix the fallout once identified -- this way of doing things fails safe, and the goal here, after all, is to _avoid_ silent integer truncations, not introduce them. Maybe one day we can reintroduce min/max as type-generic things that never silently truncate. But we should avoid doing that for a while, so that existing code has a chance to be detected by the compiler for conversion to uimin/uimax without changing the semantics until we can properly audit it all. (Who knows, maybe in some cases integer truncation is actually intended!)

1.11	15-Sep-2001	chs	branches: 1.11.2; a whole bunch of changes to improve performance and robustness under load: - remove special treatment of pager_map mappings in pmaps. this is required now, since I've removed the globals that expose the address range. pager_map now uses pmap_kenter_pa() instead of pmap_enter(), so there's no longer any need to special-case it. - eliminate struct uvm_vnode by moving its fields into struct vnode. - rewrite the pageout path. the pager is now responsible for handling the high-level requests instead of only getting control after a bunch of work has already been done on its behalf. this will allow us to UBCify LFS, which needs tighter control over its pages than other filesystems do. writing a page to disk no longer requires making it read-only, which allows us to write wired pages without causing all kinds of havoc. - use a new PG_PAGEOUT flag to indicate that a page should be freed on behalf of the pagedaemon when it's unlocked. this flag is very similar to PG_RELEASED, but unlike PG_RELEASED, PG_PAGEOUT can be cleared if the pageout fails due to eg. an indirect-block buffer being locked. this allows us to remove the "version" field from struct vm_page, and together with shrinking "loan_count" from 32 bits to 16, struct vm_page is now 4 bytes smaller. - no longer use PG_RELEASED for swap-backed pages. if the page is busy because it's being paged out, we can't release the swap slot to be reallocated until that write is complete, but unlike with vnodes we don't keep a count of in-progress writes so there's no good way to know when the write is done. instead, when we need to free a busy swap-backed page, just sleep until we can get it busy ourselves. - implement a fast-path for extending writes which allows us to avoid zeroing new pages. this substantially reduces cpu usage. - encapsulate the data used by the genfs code in a struct genfs_node, which must be the first element of the filesystem-specific vnode data for filesystems which use genfs_{get,put}pages(). - eliminate many of the UVM pagerops, since they aren't needed anymore now that the pager "put" operation is a higher-level operation. - enhance the genfs code to allow NFS to use the genfs_{get,put}pages instead of a modified copy. - clean up struct vnode by removing all the fields that used to be used by the vfs_cluster.c code (which we don't use anymore with UBC). - remove kmem_object and mb_object since they were useless. instead of allocating pages to these objects, we now just allocate pages with no object. such pages are mapped in the kernel until they are freed, so we can use the mapping to find the page to free it. this allows us to remove splvm() protection in several places. The sum of all these changes improves write throughput on my decstation 5000/200 to within 1% of the rate of NetBSD 1.5 and reduces the elapsed time for "make release" of a NetBSD 1.5 source tree on my 128MB pc to 10% less than a 1.5 kernel took.

Non 2**n block support is automatic for LKM's and conditional for kernels on "options NON_PO2_BLOCKS".

1.26	22-Jan-2013	dholland	branches: 1.26.14; Stuff UFS_ in front of a few of ufs's symbols to reduce namespace pollution. Specifically: ROOTINO -> UFS_ROOTINO WINO -> UFS_WINO NXADDR -> UFS_NXADDR NDADDR -> UFS_NDADDR NIADDR -> UFS_NIADDR MAXSYMLINKLEN -> UFS_MAXSYMLINKLEN MAXSYMLINKLEN_UFS[12] -> UFS[12]_MAXSYMLINKLEN (for consistency) Sort out ext2fs's misuse of NDADDR and NIADDR; fortunately, these have the same values in ext2fs and ffs. No functional change intended.
1.25	19-Oct-2009	bouyer	branches: 1.25.12; 1.25.22; Remove closes 3 & 4 from my licence. Lots of thanks to Soren Jacobsen for the booring work !

1.17	15-Dec-2004	mycroft	branches: 1.17.2; 1.17.4; Remove some unnecessary (int32_t) casts that would cause us to screw up the top bit in block addresses. Also, change some daddr_t->int32_t casts (mostly as arguments to ufs_rw32(), where they would get promoted anyway) to u_int32_t.
1.16	15-Aug-2004	mycroft	Fixing age old cruft: * Rather than using mnt_maxsymlinklen to indicate that a file systems returns d_type fields(!), add a new internal flag, IMNT_DTYPE. Add 3 new elements to ufsmount: * um_maxsymlinklen, replaces mnt_maxsymlinklen (which never should have existed in the first place). * um_dirblksiz, which tracks the current directory block size, eliminating the FS-specific checks littered throughout the code. This may be used later to make the block size variable. * um_maxfilesize, which is the maximum file size, possibly adjusted lower due to implementation issues. Sync some bug fixes from FFS into ext2fs, particularly: * ffs_lookup.c 1.21, 1.28, 1.33, 1.48 * ffs_inode.c 1.43, 1.44, 1.45, 1.66, 1.67 * ffs_vnops.c 1.84, 1.85, 1.86 Clean up some crappy pointer frobnication.

1.14	25-Jan-2004	hannken	Make VOP_STRATEGY(bp) a real VOP as discussed on tech-kern. VOP_STRATEGY(bp) is replaced by one of two new functions: - VOP_STRATEGY(vp, bp) Call the strategy routine of vp for bp. - DEV_STRATEGY(bp) Call the d_strategy routine of bp->b_dev for bp. DEV_STRATEGY(bp) is used only for block-to-block device situations.

1.12	07-Aug-2003	agc	Move UCB-licensed code from 4-clause to 3-clause licence. Patches provided by Joel Baker in PR 22364, verified by myself.
1.11	18-May-2003	yamt	branches: 1.11.2; make is_sequential a callback in order to achieve better lfs write clustering. since lfs always rewrite blocks into the new segment, current on-disk place of the block doesn't affect to write clustering. ok'ed by Konrad Schroder.
1.10	24-Jan-2003	fvdl	Bump daddr_t to 64 bits. Replace it with int32_t in all places where it was used on-disk, so that on-disk formats remain the same. Remove ufs_daddr_t and ufs_lbn_t for the time being.
1.9	10-Nov-2001	chs	branches: 1.9.10; update to track ufs_bmap.c: don't call ufs_getlbns() for direct blocks.

1.6	26-Oct-2001	lukem	remove #include <ufs/ufs/quota.h> where it was just to appease <ufs/ufs/inode.h>, since the latter now includes the former. leave the former in source that obviously uses specific bits of it (for completeness.)

1.4	01-Mar-1998	fvdl	branches: 1.4.14; Merge with Lite2 + local changes
1.3	09-Oct-1997	bouyer	Add byte-swapping functions (bswap16, bswap32, bswap64) to libkern. Only assembly version for i386 bswap16 and bswap32 for now (bswap64 uses bswap32). Contribution of assembly versions of these are welcome. Add byte-swapping of ext2fs metadata for big-endian systems. Tested on i386 and sparc.
1.2	24-Jul-1997	bouyer	branches: 1.2.2; ufs_getlbns needs an array of NIADDR+1 struct indir's, and not NIADDR. This fixes a panic due to stack corruption when reading larges files.

1.5.6.3	24-Jun-2002	nathanw	Curproc->curlwp renaming. Change uses of "curproc->l_proc" back to "curproc", which is more like the original use. Bare uses of "curproc" are now "curlwp". "curproc" is now #defined in proc.h as ((curlwp) ? (curlwp)->l_proc) : NULL) so that it is always safe to reference curproc (dereferencing curproc is another story, but that's always been true).

1.22	04-Aug-2016	jdolecek	rename struct ext2fs_dinode attribute e2di_dacl to correct e2di_size_high; even Linux ext2 filesystem code actually uses it unconditionally this way and ext4 code finally also calls it that way in their struct definition too; if there was any trace of this for other purpose it's long gone

1.32	04-Aug-2016	jdolecek	rename struct ext2fs_dinode attribute e2di_dacl to correct e2di_size_high; even Linux ext2 filesystem code actually uses it unconditionally this way and ext4 code finally also calls it that way in their struct definition too; if there was any trace of this for other purpose it's long gone

1.27	02-Aug-2016	jdolecek	adjust the comments for on-disk ext2fs inode to indicate which of the ext* was it implemented for linux kernel; makes it a bit easier to locate split e2di_linux_reserved3 with e2di_extra_isize and e2di_checksum_high, tag as ext4
1.26	22-Jan-2013	dholland	branches: 1.26.14; 1.26.18; Stuff UFS_ in front of a few of ufs's symbols to reduce namespace pollution. Specifically: ROOTINO -> UFS_ROOTINO WINO -> UFS_WINO NXADDR -> UFS_NXADDR NDADDR -> UFS_NDADDR NIADDR -> UFS_NIADDR MAXSYMLINKLEN -> UFS_MAXSYMLINKLEN MAXSYMLINKLEN_UFS[12] -> UFS[12]_MAXSYMLINKLEN (for consistency) Sort out ext2fs's misuse of NDADDR and NIADDR; fortunately, these have the same values in ext2fs and ffs. No functional change intended.
1.25	21-Nov-2012	jakllsch	Add various newer Ext2 superblock feature bits and inode flag bits.
1.24	19-Nov-2012	jakllsch	- Add e2di_version, e2di_nblock_high, e2di_facl_high fields to ext2fs_dinode. - Update i_e2fs_ aliases to match. - ext2fs_bswap support for these ext2fs_dinode fields. (e2di_version and e2di_facl_high replace previously reserved fields. e2di_nblock_high was formerly e2di_nfrag and e2di_fsize, however these are currently defined in e2fsprogs as only being relevant for HURD.)

1.1	03-Jun-2016	christos	Add ext4 extent support from GSoC 2016 (Hrishikesh Goyal), from the FreeBSD ext2 code.
1.2.2.3	05-Oct-2016	skrll	Sync with HEAD
1.2.2.2	09-Jul-2016	skrll	Sync with HEAD
1.2.2.1	10-Jun-2016	skrll	file ext2fs_extents.h was added on branch nick-nhusb on 2016-07-09 20:25:24 +0000
1.4.14.2	03-Dec-2017	jdolecek	update from HEAD
1.4.14.1	09-Aug-2016	jdolecek	file ext2fs_extents.h was added on branch tls-maxphys on 2017-12-03 11:39:21 +0000
1.57	26-Aug-2023	riastradh	ext2fs: Nix trailing whitespace.
1.56	28-May-2017	hannken	Change ext2fs to use vcache_new like we did for ffs: - Change ext2fs_valloc to return an inode number. - Make ext2fs_makeinode private to ext2fs_vnops.c and pass vattr instead of mode.
1.55	20-Aug-2016	jdolecek	add support for GDT_CSUM AKA uninit_bg feature
1.54	19-Aug-2016	jdolecek	fix bug introduced in rev 1.82 of ext2fs_lookup.c, when ext2fs_add_entry() was introduced splitting code from ext2fs_direnter() - code used incorrect new entry size, leading to incomplete entry copy or buffer overflow; fixed by passing the right size from ext2fs_direnter()
1.53	15-Aug-2016	jdolecek	adjust ext2fs_makeinode() so that the direnter is optional, use the function (with the direnter off) in ext2fs_mkdir() instead of the code copy; adjust ext2fs_makeinode() to initialize extra_isize and set creation time, if supported by the filesystem
1.52	09-Aug-2016	kre	Undo revert now Christos has added the missing glue...
1.51	09-Aug-2016	kre	Revert previous. This work isn't complete enough to include yet, and the build of current really does need to go back to a working state.
1.50	09-Aug-2016	christos	More htree writing support (Hrishikesh Goyal GSoC 2016)
1.49	24-Jun-2016	christos	GSoC 2016 (Hrishikesh Goyal): Htree index support from FreeBSD
1.48	27-Mar-2015	riastradh	Disentangle buffer-cached I/O from page-cached I/O in UFS. Page-cached I/O is used for regular files, and is initiated by VFS users such as userland and NFS. Buffer-cached I/O is used for directories and symlinks, and is issued only internally by UFS. New UFS routine ufs_bufio replaces vn_rdwr for internal use. ufs_bufio is implemented by new UFS operations uo_bufrd/uo_bufwr, which sit in ufs_readwrite.c alongside the VOP_READ/VOP_WRITE implementations. I preserved the code as much as possible and will leave further simplification for future commits. I kept the ulfs_readwrite.c copypasta close to ufs_readwrite.c in case we ever want to merge them back; likewise ext2fs_readwrite.c. No externally visible semantic change. All atf fs tests still pass.
1.47	25-May-2014	hannken	branches: 1.47.4; Remove ext2fs_checkpath(). It is a relic from the pre-genfs_rename era.
1.46	21-Nov-2012	jakllsch	branches: 1.46.10; Write support for the Ext4 Read-only Compatible Feature "huge_file". Primarily, this feature extends the inode block count field to 48 bits. Additionally, this feature allows this field to be represented in file system block size units rather than DEV_BSIZE units.
1.45	17-Nov-2012	jakllsch	Match prototype types to function types (u_int64_t vs. uint64_t).
1.44	09-May-2012	riastradh	branches: 1.44.2; Adapt ffs, lfs, and ext2fs to use genfs_rename. ok dholland, rmind
1.43	12-Jul-2011	dholland	branches: 1.43.2; 1.43.6; Pass the ufs_lookup_results pointer around instead of fetching it from the inode in the guts of ufs. Now, in VOPs where i_crap is used it is used (directly) only immediately on entry to the VOP call and then passed around by reference. Except for rename, which needs explicit sorting out. The code in ufs_wapbl_rename is unchanged in behavior but I'm increasingly inclined to think it's wrong.
1.42	21-Oct-2009	pooka	update i_uid and i_gid after chown
1.41	19-Oct-2009	bouyer	Remove closes 3 & 4 from my licence. Lots of thanks to Soren Jacobsen for the booring work !
1.40	12-Sep-2009	tsutsui	Reduce diffs a bit between ext2fs_reload() and ffs_reload().
1.39	28-Jun-2008	rumble	branches: 1.39.6; 1.39.14; Create sysctl entries during module initialisation and destroy them appropriately. Many of these file systems are now ready for modularisation.
1.38	08-Dec-2007	pooka	branches: 1.38.12; 1.38.16; 1.38.18; 1.38.20; Remove cn_lwp from struct componentname. curlwp should be used from on. The NDINIT() macro no longer takes the lwp parameter and associates the credentials of the calling thread with the namei structure.
1.37	26-Nov-2007	pooka	branches: 1.37.2; Remove the "struct lwp *" argument from all VFS and VOP interfaces. The general trend is to remove it from all kernel interfaces and this is a start. In case the calling lwp is desired, curlwp should be used. quick consensus on tech-kern
1.36	31-Jul-2007	pooka	branches: 1.36.2; 1.36.4; 1.36.10; 1.36.12; * nuke the nameidata parameter from VFS_MOUNT(). Nobody on tech-kern knew what it was supposed to be used for and wrstuden gave a go-ahead * while rototilling, convert file systems which went easily to use VFS_PROTOS() instead of manually prototyping the methods
1.35	12-Jul-2007	dsl	branches: 1.35.2; Change the VFS_MOUNT() interface so that the 'data' buffer passed to the fs code is a kernel buffer, pass though the length of the buffer as well. Since the length of the userspace buffer isn'it (yet) passed through the mount system call, add a field to the vfsops structure containing the default length. Split sys_mount() for calls from compat code. Ride one of the recent kernel version changes - old fs LKMs will load, but sys_mount() will reject any attempt to use them.
1.34	13-Jul-2006	martin	branches: 1.34.14; Fix alignement problems for fhandle_t, exposed by gcc4.1. While touching all vptofh/fhtovp functions, get rid of VFS_MAXFIDSIZ, version the getfh(2) syscall and explicitly pass the size available in the filehandle from userland. Discussed on tech-kern, with lots of help from yamt (thanks!).
1.33	14-May-2006	elad	branches: 1.33.4; integrate kauth.
1.32	27-Dec-2005	chs	branches: 1.32.4; 1.32.6; 1.32.8; 1.32.10; 1.32.12; changes for making DIAGNOSTIC not change the kernel ABI: - for structure fields that are conditionally present, make those fields always present. - for functions which are conditionally inline, make them never inline. - remove some other functions which are conditionally defined but don't actually do anything anymore. - make a lock-debugging function conditional on only LOCKDEBUG. as discussed on tech-kern some time back.
1.31	13-Dec-2005	christos	add fwd declaration for struct proc. Fixes vax build.
1.30	11-Dec-2005	christos	merge ktrace-lwp.
1.29	02-Nov-2005	yamt	merge yamt-vop branch. remove following VOPs. VOP_BLKATOFF VOP_VALLOC VOP_BALLOC VOP_REALLOCBLKS VOP_VFREE VOP_TRUNCATE VOP_UPDATE
1.28	12-Sep-2005	christos	branches: 1.28.2; - access the ffs and ext2fs itimes functions through a pointer, so that if the filesystem is not compiled in the kernel still links. Probably a better solution is to use weak symbols. - move the filesystem-specific itime macros to the filesystem header files.
1.27	12-Sep-2005	christos	Use nanotime() to update the time fields in filesystems. Convert the code from macros to real functions. Original patch and review from chuq. Note: ext2fs only keeps seconds in the on-disk inode, and msdosfs does not have enough precision for all fields, so this is not very useful for those two.
1.26	30-Aug-2005	xtraeme	* Remove __P() * Use ANSI function declarations on ext2fs and mfs
1.25	09-Feb-2005	ws	branches: 1.25.6; Add support for large files (>2GB). Like Linux, automagically convert old filesystem to use this, if they are already at revision 1. For revision 0, just punt (unlike Linux; makes me a bit too nervous.) There should be an option to fsck_ext2fs to upgrade revision 0 to revision 1. Reviewd by Manuel (bouyer@).
1.24	20-May-2004	atatat	branches: 1.24.4; 1.24.6; Tweak sysctl setup functions (the macros, actually) for use in lkms, and tweak lkminit_*.c (where applicable) to call them, and to call sysctl_teardown() when being unloaded. This consists of (1) making setup functions not be static when being compiled as lkms (change to sys/sysctl.h), (2) making prototypes visible for the various setup functions in header files (changes to various header files), and (3) making simple "load" and "unload" functions in the actual lkminit stuff. linux_sysctl.c also needs its root exposed (ie, made not static) for this (when built as an lkm).
1.23	21-Apr-2004	christos	Replace the statfs() family of system calls with statvfs(). Retain binary compatibility.
1.22	22-Mar-2004	bouyer	branches: 1.22.2; Fix disclaimer in my copyright. Pointed out by Thomas Klausner.
1.21	04-Dec-2003	atatat	Dynamic sysctl. Gone are the old kern_sysctl(), cpu_sysctl(), hw_sysctl(), vfs_sysctl(), etc, routines, along with sysctl_int() et al. Now all nodes are registered with the tree, and nodes can be added (or removed) easily, and I/O to and from the tree is handled generically. Since the nodes are registered with the tree, the mapping from name to number (and back again) can now be discovered, instead of having to be hard coded. Adding new nodes to the tree is likewise much simpler -- the new infrastructure handles almost all the work for simple types, and just about anything else can be done with a small helper function. All existing nodes are where they were before (numerically speaking), so all existing consumers of sysctl information should notice no difference. PS - I'm sorry, but there's a distinct lack of documentation at the moment. I'm working on sysctl(3/8/9) right now, and I promise to watch out for buses.
1.20	05-Oct-2003	bouyer	Remove references to University of California from my copyright notices.
1.19	07-Aug-2003	agc	Move UCB-licensed code from 4-clause to 3-clause licence. Patches provided by Joel Baker in PR 22364, verified by myself.
1.18	29-Jun-2003	fvdl	branches: 1.18.2; Back out the lwp/ktrace changes. They contained a lot of colateral damage, and need to be examined and discussed more.
1.17	29-Jun-2003	thorpej	Undo part of the ktrace/lwp changes. In particular: * Remove the "lwp " argument that was added to vget(). Turns out that nothing actually used it! Remove the "lwp " arguments that were added to VFS_ROOT(), VFS_VGET(), and VFS_FHTOVP(); all they did was pass it to vget() (which, as noted above, didn't use it). Remove all of the "lwp *" arguments to internal functions that were added just to appease the above.
1.16	28-Jun-2003	darrenr	Pass lwp pointers throughtout the kernel, as required, so that the lwpid can be inserted into ktrace records. The general change has been to replace "struct proc " with "struct lwp " in various function prototypes, pass the lwp through and use l_proc to get the process pointer when needed. Bump the kernel rev up to 1.6V
1.15	26-May-2003	fvdl	free the ext2fs dinode struct in ext2fs_reclaim. From Ted Unangst.
1.14	24-Jan-2003	fvdl	Bump daddr_t to 64 bits. Replace it with int32_t in all places where it was used on-disk, so that on-disk formats remain the same. Remove ufs_daddr_t and ufs_lbn_t for the time being.
1.13	01-Dec-2002	matt	Add multiple inclusion protection for headers. Fix mismatched variable declarations (missing const's) as needed.
1.12	26-Sep-2002	jdolecek	use ufs_balloc_range() rather than local (mostly identical, but with some bugs) ext2fs variant
1.11	15-Sep-2001	chs	a whole bunch of changes to improve performance and robustness under load: - remove special treatment of pager_map mappings in pmaps. this is required now, since I've removed the globals that expose the address range. pager_map now uses pmap_kenter_pa() instead of pmap_enter(), so there's no longer any need to special-case it. - eliminate struct uvm_vnode by moving its fields into struct vnode. - rewrite the pageout path. the pager is now responsible for handling the high-level requests instead of only getting control after a bunch of work has already been done on its behalf. this will allow us to UBCify LFS, which needs tighter control over its pages than other filesystems do. writing a page to disk no longer requires making it read-only, which allows us to write wired pages without causing all kinds of havoc. - use a new PG_PAGEOUT flag to indicate that a page should be freed on behalf of the pagedaemon when it's unlocked. this flag is very similar to PG_RELEASED, but unlike PG_RELEASED, PG_PAGEOUT can be cleared if the pageout fails due to eg. an indirect-block buffer being locked. this allows us to remove the "version" field from struct vm_page, and together with shrinking "loan_count" from 32 bits to 16, struct vm_page is now 4 bytes smaller. - no longer use PG_RELEASED for swap-backed pages. if the page is busy because it's being paged out, we can't release the swap slot to be reallocated until that write is complete, but unlike with vnodes we don't keep a count of in-progress writes so there's no good way to know when the write is done. instead, when we need to free a busy swap-backed page, just sleep until we can get it busy ourselves. - implement a fast-path for extending writes which allows us to avoid zeroing new pages. this substantially reduces cpu usage. - encapsulate the data used by the genfs code in a struct genfs_node, which must be the first element of the filesystem-specific vnode data for filesystems which use genfs_{get,put}pages(). - eliminate many of the UVM pagerops, since they aren't needed anymore now that the pager "put" operation is a higher-level operation. - enhance the genfs code to allow NFS to use the genfs_{get,put}pages instead of a modified copy. - clean up struct vnode by removing all the fields that used to be used by the vfs_cluster.c code (which we don't use anymore with UBC). - remove kmem_object and mb_object since they were useless. instead of allocating pages to these objects, we now just allocate pages with no object. such pages are mapped in the kernel until they are freed, so we can use the mapping to find the page to free it. this allows us to remove splvm() protection in several places. The sum of all these changes improves write throughput on my decstation 5000/200 to within 1% of the rate of NetBSD 1.5 and reduces the elapsed time for "make release" of a NetBSD 1.5 source tree on my 128MB pc to 10% less than a 1.5 kernel took.
1.10	15-Sep-2001	chs	add a new VFS op, vfs_reinit, which is called when desiredvnodes is adjusted via sysctl. file systems that have hash tables which are sized based on the value of this variable now resize those hash tables using the new value. the max number of FFS softdeps is also recalculated. convert various file systems to use the <sys/queue.h> macros for their hash tables.
1.9	27-Nov-2000	chs	branches: 1.9.2; 1.9.6; 1.9.8; Initial integration of the Unified Buffer Cache project.
1.8	16-Mar-2000	jdolecek	Add new VFS op routine - vfs_done and call it on filesystem detach in vfs_detach(). vfs_done may free global filesystem's resources, typically those allocated in respective filesystem's init function. Needed so those filesystems which went in via LKM have a chance to clean after themselves before unloading. This fixes random panics when LKM for filesystem using pools was loaded and unloaded several times. For each leaf filesystem, add appropriate vfs_done routine.
1.7	26-Feb-1999	wrstuden	branches: 1.7.4; 1.7.8; Modify vfsops to seperate vfs_fhtovp() into two routines. vfs_fhtovp() now only handles the file handle to vnode conversion, and a new call, vfs_checkexp(), performs the export verification.
1.6	01-Sep-1998	thorpej	Use the pool allocator and "nointr" pool page allocator for ext2fs inodes.
1.5	24-Jun-1998	sommerfe	Always include fifos; "not an option any more".
1.4	23-Jun-1998	sommerfe	Don't include opt_fifo.h if not kernel...

1.2	01-Mar-1998	fvdl	Merge with Lite2 + local changes

1.18.2.1	02-Jul-2003	darrenr	Apply the aborted ktrace-lwp changes to a specific branch. This is just for others to review, I'm concerned that patch fuziness may have resulted in some errant code being generated but I'll look at that later by comparing the diff from the base to the branch with the file I attempt to apply to it. This will, at the very least, put the changes in a better context for others to review them and attempt to tinker with removing passing of 'struct lwp' through the kernel.
1.22.2.1	23-May-2004	tron	Pull up revision 1.24 (requested by atatat in ticket #374): Tweak sysctl setup functions (the macros, actually) for use in lkms, and tweak lkminit_*.c (where applicable) to call them, and to call sysctl_teardown() when being unloaded.

Use it to decide whether to do direct-mapped copy, rather than poking around directly in the vnode in ubc_uiomove(), which is ugly and doesn't work for tmpfs. It would be nicer to contain all this in UVM but the filesystem provides the needed locking here (VV_MAPPED) and to reinvent that would suck more. - Rename UBC_UNMAP_FLAG() to UBC_VNODE_FLAGS(). Pass in UBC_ISMAPPED where appropriate.

1.42	14-Aug-2004	mycroft	Push atime/mtime updates even further -- into the reclaim path, so they happen rarely in the normal case. (Note: This happens at reboot/shutdown time because all file systems are unmounted.) Also, for IN_MODIFY, use IN_ACCESSED, not IN_MODIFIED; otherwise "ls -l" of your device node or FIFO would cause the time stamps to get written too quickly.
1.41	14-Aug-2004	mycroft	Add a new flag, IN_MODIFY. This is like IN_UPDATE\|IN_CHANGE, but unlike setting those flags, it does not cause the inode to be written in the periodic sync. This is used for writes to special files (devices and named pipes) and FIFOs. Do not preemptively sync updates to access times and modification times. They are now updated in the inode only opportunistically, or when the file or device is closed. (Really, it should be delayed beyond close, but this is enough to help substantially with device nodes.) And the most amusing part: Trickle sync was broken on both FFS and ext2fs, in different ways. In FFS, the periodic call to VFS_SYNC(MNT_LAZY) was still causing all file data to be synced. In ext2fs, it was causing the metadata to not be synced. We now only call VOP_UPDATE() on the node if we're doing MNT_LAZY. I've confirmed that we do in fact trickle correctly now.

1.15	13-May-2000	perseant	branches: 1.15.2; Change the sementics of the last parameter from a boolean ("waitfor") to a set of flags ("flags"). Two flags are defined, UPDATE_WAIT and UPDATE_DIROP. Under the old semantics, VOP_UPDATE would block if waitfor were set, under the assumption that directory operations should be done synchronously. At least LFS and FFS+softdep do not make this assumption; FFS+softdep got around the problem by enclosing all relevant calls to VOP_UPDATE in a "if(!DOINGSOFTDEP(vp))", while LFS simply ignored waitfor, one of the reasons why NFS-serving an LFS filesystem did not work properly. Under the new semantics, the UPDATE_DIROP flag is a hint to the fs-specific update routine that the call comes from a dirop routine, and should be wait for, or not, accordingly. Closes PR#8996.

1.6	01-Mar-1998	fvdl	Merge with Lite2 + local changes
1.5	10-Feb-1998	mrg	- add defopt's for UVM, UVMHIST and PMAP_NEW. - remove unnecessary UVMHIST_DECL's.
1.4	05-Feb-1998	mrg	initial import of the new virtual memory system, UVM, into -current. UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some minor portions derived from the old Mach code. i provided some help getting swap and paging working, and other bug fixes/ideas. chuck silvers <chuq@chuq.com> also provided some other fixes. this is the rest of the MI portion changes. this will be KNF'd shortly. :-)
1.3	09-Oct-1997	bouyer	Add byte-swapping functions (bswap16, bswap32, bswap64) to libkern. Only assembly version for i386 bswap16 and bswap32 for now (bswap64 uses bswap32). Contribution of assembly versions of these are welcome. Add byte-swapping of ext2fs metadata for big-endian systems. Tested on i386 and sparc.
1.2	04-Jul-1997	drochner	branches: 1.2.2; Don't cast 64bit (off_t) file sizes to vm_offset_t (32bit on many architectures), truncate them intelligently instead. The truncation is done centralized in vnode_pager.c. This prevents from wrap-over effects when parts of large (>2^32 byte) files are mmapped. Don't allow to mmap above the numerical range of vm_offset_t. This is considered a temporary solution until the vm system handles the object sizes/offsets more cleanly.
1.1	11-Jun-1997	bouyer	The ext2fs layer, based on the ffs/ufs one. Uses a few functions from sys/ufs/ufs/
1.2.2.1	14-Oct-1997	thorpej	Update marc-pcmcia branch from trunk.
1.13.14.1	21-Dec-1999	wrstuden	Initial commit of recent changes to make DEV_BSIZE go away. Runs on i386, needs work on other arch's. Main kernel routines should be fine, but a number of the stand programs need help. cd, fd, ccd, wd, and sd have been updated. sd has been tested with non-512 byte block devices. vnd, raidframe, and lfs need work. Non 2**n block support is automatic for LKM's and conditional for kernels on "options NON_PO2_BLOCKS".

1.23.2.4	24-Jun-2002	nathanw	Curproc->curlwp renaming. Change uses of "curproc->l_proc" back to "curproc", which is more like the original use. Bare uses of "curproc" are now "curlwp". "curproc" is now #defined in proc.h as ((curlwp) ? (curlwp)->l_proc) : NULL) so that it is always safe to reference curproc (dereferencing curproc is another story, but that's always been true).

This will, at the very least, put the changes in a better context for others to review them and attempt to tinker with removing passing of 'struct lwp' through the kernel.

Not adjusting v_writesize to the real size cause genfs_do_io() to write to disk past the real end of the file.

Possible future enhancements: - make the lookups lockless. - support dotdot lookups by being lockless and inferring absence of chroot. - maybe make it work for layered file systems. - avoid vnode references at the root & cwd.

1.79	12-Jan-2016	riastradh	Use buffer cache, not page cache, to expand directories in ext2fs. Candidate fix for PR kern/50607, PR port-evbmips/50059. Formerly VOP_WRITE-->ext2fs_write would automatically dispatch to this code path for writes to directories, but I broke that in ext2fs_lookup.c rev. 1.78 when disentangling page-cached and buffer-cached writes. This was not a problem in ufs, and I didn't notice it in ext2fs, because ufs consistently used buffercache(9) directly instead of using VOP_WRITE sometimes as ext2fs did.
1.78	27-Mar-2015	riastradh	Disentangle buffer-cached I/O from page-cached I/O in UFS. Page-cached I/O is used for regular files, and is initiated by VFS users such as userland and NFS. Buffer-cached I/O is used for directories and symlinks, and is issued only internally by UFS. New UFS routine ufs_bufio replaces vn_rdwr for internal use. ufs_bufio is implemented by new UFS operations uo_bufrd/uo_bufwr, which sit in ufs_readwrite.c alongside the VOP_READ/VOP_WRITE implementations. I preserved the code as much as possible and will leave further simplification for future commits. I kept the ulfs_readwrite.c copypasta close to ufs_readwrite.c in case we ever want to merge them back; likewise ext2fs_readwrite.c. No externally visible semantic change. All atf fs tests still pass.

1.75	08-May-2014	hannken	Add a global vnode cache: - vcache_get() retrieves a referenced and initialised vnode / fs node pair. - vcache_remove() removes a vnode / fs node pair from the cache. On cache miss vcache_get() calls new vfs operation vfs_loadvnode() to initialise a vnode / fs node pair. This call is guaranteed exclusive, no other thread will try to load this vnode / fs node pair. Convert ufs/ext2fs, ufs/ffs and ufs/mfs to use this interface. Remove now unused ufs/ufs_ihash Discussed on tech-kern. Welcome to 6.99.41

1.73	22-Jan-2013	dholland	branches: 1.73.2; Stuff UFS_ in front of a few of ufs's symbols to reduce namespace pollution. Specifically: ROOTINO -> UFS_ROOTINO WINO -> UFS_WINO NXADDR -> UFS_NXADDR NDADDR -> UFS_NDADDR NIADDR -> UFS_NIADDR MAXSYMLINKLEN -> UFS_MAXSYMLINKLEN MAXSYMLINKLEN_UFS[12] -> UFS[12]_MAXSYMLINKLEN (for consistency) Sort out ext2fs's misuse of NDADDR and NIADDR; fortunately, these have the same values in ext2fs and ffs. No functional change intended.
1.72	05-Nov-2012	dholland	Excise struct componentname from the namecache. This uglifies the interface, because several operations need to be passed the namei flags and cache_lookup also needs for the time being to be passed cnp->cn_nameiop. Nonetheless, it's a net benefit. The glop should be able to go away eventually but requires structural cleanup elsewhere first. This change requires a kernel bump.
1.71	05-Nov-2012	dholland	Disentangle the namecache from the internals of namei. - Move the namecache's hash computation to inside the namecache code, instead of being spread out all over the place. Remove cn_hash from struct componentname and delete all uses of it. - It is no longer necessary (if it ever was) for cache_lookup and cache_lookup_raw to clear MAKEENTRY from cnp->cn_flags for the cases that cache_enter already checks for. - Rearrange the interface of cache_lookup (and cache_lookup_raw) to make it somewhat simpler, to exclude certain nonexistent error conditions, and (most importantly) to make it not require write access to cnp->cn_flags. This change requires a kernel bump.
1.70	22-Jul-2012	rmind	branches: 1.70.2; Move some the test for MAKEENTRY into the cache_enter(9). Make some variables in vfs_cache.c static, __read_mostly, etc. No objection on tech-kern@.

1.67	27-Jan-2012	para	branches: 1.67.2; converting readdir in ffs ext2fs from malloc(9) to kmem(9) while there allocate ufs mount structs from kmem(9) too preceding kmem-vmem-pool-patch releng@ acknowledged
1.66	12-Jul-2011	dholland	branches: 1.66.2; 1.66.6; Pass the ufs_lookup_results pointer around instead of fetching it from the inode in the guts of ufs. Now, in VOPs where i_crap is used it is used (directly) only immediately on entry to the VOP call and then passed around by reference. Except for rename, which needs explicit sorting out. The code in ufs_wapbl_rename is unchanged in behavior but I'm increasingly inclined to think it's wrong.
1.65	12-Jul-2011	dholland	Currently, ufs_lookup produces five auxiliary results that are left in the vnode when lookup returns and fished out again later. 1. Create struct ufs_lookup_results to hold these. 2. Call the ufs_lookup_results instance in struct inode "i_crap" to be clear about exactly what's going on, and to distinguish the lookup results from respectable members of struct inode. 3. Update references to these members in the directory access subroutines. 4. Include preliminary infrastructure for checking that the i_crap being used is still valid when it's used. This doesn't actually do anything yet. 5. Update the way ufs_wapbl_rename manipulates these elements to use the new data structures. I have not changed the manipulation; it may or may not be correct but I continue to suspect that it is not. The word of the day is "stigmergy".
1.64	11-Jul-2011	hannken	Change VOP_BWRITE() to take a vnode as its first argument like all other VOPs do. Layered file systems no longer have to modify bp->b_vp and run into trouble when an async VOP_BWRITE() uses the wrong vnode. - change all occurences of VOP_BWRITE(bp) to VOP_BWRITE(bp->b_vp, bp). - remove layer_bwrite(). - welcome to 5.99.55 Adresses PR kern/38762 panic: vwakeup: neg numoutput No objections from tech-kern@.
1.63	30-Nov-2010	dholland	Abolish the SAVENAME and HASBUF flags. There is now always a buffer, so the path in a struct componentname is now always valid during VOP calls.

1.47	09-Dec-2006	chs	a smorgasbord of improvements to vnode locking and path lookup: - LOCKPARENT is no longer relevant for lookup(), relookup() or VOP_LOOKUP(). these now always return the parent vnode locked. namei() works as before. lookup() and various other paths no longer acquire vnode locks in the wrong order via vrele(). fixes PR 32535. as a nice side effect, path lookup is also up to 25% faster. - the above allows us to get rid of PDIRUNLOCK. - also get rid of WANTPARENT (just use LOCKPARENT and unlock it). - remove an assumption in layer_node_find() that all file systems implement a recursive VOP_LOCK() (unionfs doesn't). - require that all file systems supply vfs_vptofh and vfs_fhtovp routines. fill in eopnotsupp() for file systems that don't support being exported and remove the checks for NULL. (layerfs calls these without checking.) - in union_lookup1(), don't change refcounts in the ISDOTDOT case, just adjust which vnode is locked. fixes PR 33374. - apply fixes for ufs_rename() from ufs_vnops.c rev. 1.61 to ext2fs_rename().

Add 3 new elements to ufsmount: * um_maxsymlinklen, replaces mnt_maxsymlinklen (which never should have existed in the first place). * um_dirblksiz, which tracks the current directory block size, eliminating the FS-specific checks littered throughout the code. This may be used later to make the block size variable. * um_maxfilesize, which is the maximum file size, possibly adjusted lower due to implementation issues. Sync some bug fixes from FFS into ext2fs, particularly: * ffs_lookup.c 1.21, 1.28, 1.33, 1.48 * ffs_inode.c 1.43, 1.44, 1.45, 1.66, 1.67 * ffs_vnops.c 1.84, 1.85, 1.86 Clean up some crappy pointer frobnication.

Remove the "lwp " arguments that were added to VFS_ROOT(), VFS_VGET(), and VFS_FHTOVP(); all they did was pass it to vget() (which, as noted above, didn't use it). Remove all of the "lwp *" arguments to internal functions that were added just to appease the above.
1.25	28-Jun-2003	darrenr	Pass lwp pointers throughtout the kernel, as required, so that the lwpid can be inserted into ktrace records. The general change has been to replace "struct proc " with "struct lwp " in various function prototypes, pass the lwp through and use l_proc to get the process pointer when needed. Bump the kernel rev up to 1.6V
1.24	02-Apr-2003	fvdl	Add support for UFS2. UFS2 is an enhanced FFS, adding support for 64 bit block pointers, extended attribute storage, and a few other things. This commit does not yet include the code to manipulate the extended storage (for e.g. ACLs), this will be done later. Originally written by Kirk McKusick and Network Associates Laboratories for FreeBSD.

1.79	19-Oct-2024	jakllsch	ufs: base amount of data to sync on MAXPHYS instead of constant No functional change except on sun2 and sun3, as ilog2(MAXPHYS) is the same as the previous constant (16) on all other ports. On sun[23] this changes amount written from 56KiB/8KiB to 2x 32KiB.
1.78	20-Oct-2021	thorpej	branches: 1.78.10; Overhaul of the EVFILT_VNODE kevent(2) filter: - Centralize vnode kevent handling in the VOP_() wrappers, rather than forcing each individual file system to deal with it (except VOP_RENAME(), because VOP_RENAME() is a mess and we currently have 2 different ways of handling it; at least it's reasonably well-centralized in the "new" way). - Add support for NOTE_OPEN, NOTE_CLOSE, NOTE_CLOSE_WRITE, and NOTE_READ, compatible with the same events in FreeBSD. - Track which kevent notifications clients are interested in receiving to avoid doing work for events no one cares about (avoiding, e.g. taking locks and traversing the klist to send a NOTE_WRITE when someone is merely watching for a file to be deleted, for example). In support of the above: - Add support in vnode_if.sh for specifying PRE- and POST-op handlers, to be invoked before and after vop_pre() and vop_post(), respectively. Basic idea from FreeBSD, but implemented differently. - Add support in vnode_if.sh for specifying CONTEXT fields in the vop__args structures. These context fields are used to convey information between the file system VOP function and the VOP wrapper, but do not occupy an argument slot in the VOP_*() call itself. These context fields are initialized and subsequently interpreted by PRE- and POST-op handlers. - Version VOP_REMOVE(), uses the a context field for the file system to report back the resulting link count of the target vnode. Return this in tmpfs, udf, nfs, chfs, ext2fs, lfs, and ufs. NetBSD 9.99.92.
1.77	23-Apr-2020	ad	PR kern/54759 (vm.ubc_direct deadlock when read()/write() into mapping of itself) - Add new flag UBC_ISMAPPED which tells ubc_uiomove() the object is mmap()ed somewhere. Use it to decide whether to do direct-mapped copy, rather than poking around directly in the vnode in ubc_uiomove(), which is ugly and doesn't work for tmpfs. It would be nicer to contain all this in UVM but the filesystem provides the needed locking here (VV_MAPPED) and to reinvent that would suck more. - Rename UBC_UNMAP_FLAG() to UBC_VNODE_FLAGS(). Pass in UBC_ISMAPPED where appropriate.
1.76	23-Feb-2020	ad	branches: 1.76.4; UVM locking changes, proposed on tech-kern: - Change the lock on uvm_object, vm_amap and vm_anon to be a RW lock. - Break v_interlock and vmobjlock apart. v_interlock remains a mutex. - Do partial PV list locking in the x86 pmap. Others to follow later.

1.68	28-Mar-2015	riastradh	Missed a spot in ext2fs_read
1.67	27-Mar-2015	riastradh	Disentangle buffer-cached I/O from page-cached I/O in UFS. Page-cached I/O is used for regular files, and is initiated by VFS users such as userland and NFS. Buffer-cached I/O is used for directories and symlinks, and is issued only internally by UFS. New UFS routine ufs_bufio replaces vn_rdwr for internal use. ufs_bufio is implemented by new UFS operations uo_bufrd/uo_bufwr, which sit in ufs_readwrite.c alongside the VOP_READ/VOP_WRITE implementations. I preserved the code as much as possible and will leave further simplification for future commits. I kept the ulfs_readwrite.c copypasta close to ufs_readwrite.c in case we ever want to merge them back; likewise ext2fs_readwrite.c. No externally visible semantic change. All atf fs tests still pass.

1.63	19-Jun-2013	dholland	Rename ambiguous macros: MAXDIRSIZE -> UFS_MAXDIRSIZE or LFS_MAXDIRSIZE NINDIR -> FFS_NINDIR, EXT2_NINDIR, LFS_NINDIR, or MFS_NINDIR INOPB -> FFS_INOPB, LFS_INOPB INOPF -> FFS_INOPF, LFS_INOPF blksize -> ffs_blksize, ext2_blksize, or lfs_blksize sblksize -> ffs_blksize These are not the only ambiguously defined filesystem macros, of course, there's a pile more. I may not have found all the ambiguous definitions of blksize(), too, as there are a lot of other things called 'blksize' in the system.
1.62	21-Nov-2012	jakllsch	Write support for the Ext4 Read-only Compatible Feature "huge_file". Primarily, this feature extends the inode block count field to 48 bits. Additionally, this feature allows this field to be represented in file system block size units rather than DEV_BSIZE units.
1.61	29-Apr-2012	chs	branches: 1.61.2; change vflushbuf() to take the full FSYNC_* flags. translate FSYNC_LAZY into PGO_LAZY for VOP_PUTPAGES() so that genfs_do_io() can set the appropriate io priority for the I/O. this is the first part of addressing PR 46325.

1.57	12-Jun-2011	rmind	branches: 1.57.2; Welcome to 5.99.53! Merge rmind-uvmplock branch: - Reorganize locking in UVM and provide extra serialisation for pmap(9). New lock order: [vmpage-owner-lock] -> pmap-lock. - Simplify locking in some pmap(9) modules by removing P->V locking. - Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs). - Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner. Add TLBSTATS option for x86 to collect statistics about TLB shootdowns. - Unify /dev/mem et al in MI code and provide required locking (removes kernel-lock on some ports). Also, avoid cache-aliasing issues. Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches formed the core changes of this branch.
1.56	23-Apr-2010	pooka	branches: 1.56.6; Enforce RLIMIT_FSIZE before VOP_WRITE. This adds support to file system drivers where it was missing from and fixes one buggy implementation. The arguably weird semantics of the check are maintained (v_size vs. va_bytes, overwrite).

The LP_UFSCOW hack is no longer needed to protect ffs_copyonwrite() against endless recursion. - Add a flag B_MODIFY to bread(), breada() and breadn(). If set the caller intends to modify the buffer returned. - Always run copy-on-write on buffers returned from ffs_balloc(). - Add new function ffs_getblk() that gets a buffer, assigns a new blkno, may clear the buffer and runs copy-on-write. Process possible errors from getblk() or fscow_run(). Part of PR kern/38664. Welcome to 4.99.63 Reviewed by: YAMAMOTO Takashi <yamt@netbsd.org>
1.51	24-Apr-2008	ad	branches: 1.51.2; 1.51.4; Network protocol interrupts can now block on locks, so merge the globals proclist_mutex and proclist_lock into a single adaptive mutex (proc_lock). Implications: - Inspecting process state requires thread context, so signals can no longer be sent from a hardware interrupt handler. Signal activity must be deferred to a soft interrupt or kthread. - As the proc state locking is simplified, it's now safe to take exit() and wait() out from under kernel_lock. - The system spends less time at IPL_SCHED, and there is less lock activity.

1.35	09-Jan-2005	chs	branches: 1.35.2; 1.35.4; adjust the UBC mapping code to support non-vnode uvm_objects. this means we can no longer look at the vnode size to determine how many pages to request in a fault, which is good since for NFS the size can change out from under us on the server anyway. there's also a new flag UBC_UNMAP for ubc_release(), so that the file system code can make the decision about whether to cache mappings for files being used as executables.

1.18	22-Sep-2001	chs	branches: 1.18.2; check early for reads beyond EOF.
1.17	15-Sep-2001	chs	a whole bunch of changes to improve performance and robustness under load: - remove special treatment of pager_map mappings in pmaps. this is required now, since I've removed the globals that expose the address range. pager_map now uses pmap_kenter_pa() instead of pmap_enter(), so there's no longer any need to special-case it. - eliminate struct uvm_vnode by moving its fields into struct vnode. - rewrite the pageout path. the pager is now responsible for handling the high-level requests instead of only getting control after a bunch of work has already been done on its behalf. this will allow us to UBCify LFS, which needs tighter control over its pages than other filesystems do. writing a page to disk no longer requires making it read-only, which allows us to write wired pages without causing all kinds of havoc. - use a new PG_PAGEOUT flag to indicate that a page should be freed on behalf of the pagedaemon when it's unlocked. this flag is very similar to PG_RELEASED, but unlike PG_RELEASED, PG_PAGEOUT can be cleared if the pageout fails due to eg. an indirect-block buffer being locked. this allows us to remove the "version" field from struct vm_page, and together with shrinking "loan_count" from 32 bits to 16, struct vm_page is now 4 bytes smaller. - no longer use PG_RELEASED for swap-backed pages. if the page is busy because it's being paged out, we can't release the swap slot to be reallocated until that write is complete, but unlike with vnodes we don't keep a count of in-progress writes so there's no good way to know when the write is done. instead, when we need to free a busy swap-backed page, just sleep until we can get it busy ourselves. - implement a fast-path for extending writes which allows us to avoid zeroing new pages. this substantially reduces cpu usage. - encapsulate the data used by the genfs code in a struct genfs_node, which must be the first element of the filesystem-specific vnode data for filesystems which use genfs_{get,put}pages(). - eliminate many of the UVM pagerops, since they aren't needed anymore now that the pager "put" operation is a higher-level operation. - enhance the genfs code to allow NFS to use the genfs_{get,put}pages instead of a modified copy. - clean up struct vnode by removing all the fields that used to be used by the vfs_cluster.c code (which we don't use anymore with UBC). - remove kmem_object and mb_object since they were useless. instead of allocating pages to these objects, we now just allocate pages with no object. such pages are mapped in the kernel until they are freed, so we can use the mapping to find the page to free it. this allows us to remove splvm() protection in several places. The sum of all these changes improves write throughput on my decstation 5000/200 to within 1% of the rate of NetBSD 1.5 and reduces the elapsed time for "make release" of a NetBSD 1.5 source tree on my 128MB pc to 10% less than a 1.5 kernel took.
1.16	27-Feb-2001	chs	branches: 1.16.2; 1.16.6; 1.16.8; min() -> MIN(), max() -> MAX(). fixes more problems with file offsets > 4GB.

1.12	13-May-2000	perseant	Change the sementics of the last parameter from a boolean ("waitfor") to a set of flags ("flags"). Two flags are defined, UPDATE_WAIT and UPDATE_DIROP. Under the old semantics, VOP_UPDATE would block if waitfor were set, under the assumption that directory operations should be done synchronously. At least LFS and FFS+softdep do not make this assumption; FFS+softdep got around the problem by enclosing all relevant calls to VOP_UPDATE in a "if(!DOINGSOFTDEP(vp))", while LFS simply ignored waitfor, one of the reasons why NFS-serving an LFS filesystem did not work properly. Under the new semantics, the UPDATE_DIROP flag is a hint to the fs-specific update routine that the call comes from a dirop routine, and should be wait for, or not, accordingly. Closes PR#8996.
1.11	30-Mar-2000	augustss	Remove register declarations.
1.10	24-Mar-1999	mrg	branches: 1.10.4; 1.10.8; completely remove Mach VM support. all that is left is the all the header files as UVM still uses (most of) these.
1.9	05-Mar-1999	mycroft	Pass null pointers to VOP_UPDATE rather than having all the callers fetch the current time themselves.
1.8	29-Sep-1998	bouyer	#include opt_uvm.h only if _KENREL and !_LKM Make ext2fs_init() call ufs_init(). it was doing the init by itself, testing for extern done != 0. This bug was hidden by the fact that ext2fs_init() is called before ffs_init().
1.7	02-Aug-1998	kleink	Implement support for IEEE Std 1003.1b-1993 synchronous I/O: * in the read vnode operator, check for IO_SYNC being set in the ioflag and synchronously update the file's meta-data if appropriate. * in the write vnode operator, update the appropriate checks for IO_SYNC being set in the ioflag to reflect that IO_DSYNC is now inclusive-or'ed into IO_SYNC, and require all IO_SYNC bits to be set for operations defined by synchronized I/O file integrity completion but not by synchronized I/O data integrity completion.
1.6	01-Mar-1998	fvdl	Merge with Lite2 + local changes
1.5	10-Feb-1998	mrg	- add defopt's for UVM, UVMHIST and PMAP_NEW. - remove unnecessary UVMHIST_DECL's.
1.4	05-Feb-1998	mrg	initial import of the new virtual memory system, UVM, into -current. UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some minor portions derived from the old Mach code. i provided some help getting swap and paging working, and other bug fixes/ideas. chuck silvers <chuq@chuq.com> also provided some other fixes. this is the rest of the MI portion changes. this will be KNF'd shortly. :-)
1.3	23-Oct-1997	bouyer	Uses ext2fs_vinit not ufs_vinit. In ext2fs, an inode is deleted either when mode == 0 or dtime != 0. If dtime != 0, reset others fields before using the inode, or we could end up with the wrong v_op in ext2fs_vinit. While I'm there, kill a unused variable in ext2fs_readwrite
1.2	04-Jul-1997	drochner	branches: 1.2.6; Don't cast 64bit (off_t) file sizes to vm_offset_t (32bit on many architectures), truncate them intelligently instead. The truncation is done centralized in vnode_pager.c. This prevents from wrap-over effects when parts of large (>2^32 byte) files are mmapped. Don't allow to mmap above the numerical range of vm_offset_t. This is considered a temporary solution until the vm system handles the object sizes/offsets more cleanly.
1.1	11-Jun-1997	bouyer	The ext2fs layer, based on the ffs/ufs one. Uses a few functions from sys/ufs/ufs/

This is just for others to review, I'm concerned that patch fuziness may have resulted in some errant code being generated but I'll look at that later by comparing the diff from the base to the branch with the file I attempt to apply to it. This will, at the very least, put the changes in a better context for others to review them and attempt to tinker with removing passing of 'struct lwp' through the kernel.

1.12	20-Oct-2021	thorpej	Overhaul of the EVFILT_VNODE kevent(2) filter: - Centralize vnode kevent handling in the VOP_() wrappers, rather than forcing each individual file system to deal with it (except VOP_RENAME(), because VOP_RENAME() is a mess and we currently have 2 different ways of handling it; at least it's reasonably well-centralized in the "new" way). - Add support for NOTE_OPEN, NOTE_CLOSE, NOTE_CLOSE_WRITE, and NOTE_READ, compatible with the same events in FreeBSD. - Track which kevent notifications clients are interested in receiving to avoid doing work for events no one cares about (avoiding, e.g. taking locks and traversing the klist to send a NOTE_WRITE when someone is merely watching for a file to be deleted, for example). In support of the above: - Add support in vnode_if.sh for specifying PRE- and POST-op handlers, to be invoked before and after vop_pre() and vop_post(), respectively. Basic idea from FreeBSD, but implemented differently. - Add support in vnode_if.sh for specifying CONTEXT fields in the vop__args structures. These context fields are used to convey information between the file system VOP function and the VOP wrapper, but do not occupy an argument slot in the VOP_*() call itself. These context fields are initialized and subsequently interpreted by PRE- and POST-op handlers. - Version VOP_REMOVE(), uses the a context field for the file system to report back the resulting link count of the target vnode. Return this in tmpfs, udf, nfs, chfs, ext2fs, lfs, and ufs. NetBSD 9.99.92.

1.8	27-Mar-2015	riastradh	Disentangle buffer-cached I/O from page-cached I/O in UFS. Page-cached I/O is used for regular files, and is initiated by VFS users such as userland and NFS. Buffer-cached I/O is used for directories and symlinks, and is issued only internally by UFS. New UFS routine ufs_bufio replaces vn_rdwr for internal use. ufs_bufio is implemented by new UFS operations uo_bufrd/uo_bufwr, which sit in ufs_readwrite.c alongside the VOP_READ/VOP_WRITE implementations. I preserved the code as much as possible and will leave further simplification for future commits. I kept the ulfs_readwrite.c copypasta close to ufs_readwrite.c in case we ever want to merge them back; likewise ext2fs_readwrite.c. No externally visible semantic change. All atf fs tests still pass.

1.12	30-Dec-2003	pk	Replace the traditional buffer memory management -- based on fixed per buffer virtual memory reservation and a private pool of memory pages -- by a scheme based on memory pools. This allows better utilization of memory because buffers can now be allocated with a granularity finer than the system's native page size (useful for filesystems with e.g. 1k or 2k fragment sizes). It also avoids fragmentation of virtual to physical memory mappings (due to the former fixed virtual address reservation) resulting in better utilization of MMU resources on some platforms. Finally, the scheme is more flexible by allowing run-time decisions on the amount of memory to be used for buffers. On the other hand, the effectiveness of the LRU queue for buffer recycling may be somewhat reduced compared to the traditional method since, due to the nature of the pool based memory allocation, the actual least recently used buffer may release its memory to a pool different from the one needed by a newly allocated buffer. However, this effect will kick in only if the system is under memory pressure.

1.189	22-Feb-2015	maxv	Merge _sbcompute() and _sbcheck() into _sbfill(). In ext2fs_sbfill(), check more fields of the superblock, to prevent several kernel panics when mounting/unmounting a disk.
1.188	20-Feb-2015	maxv	Several fixes: - rename ext2fs_checksb() -> ext2fs_sbcheck(): more consistent - in ext2fs_sbcheck(), add a check to ensure e2fs_inode_size!=0, otherwise division by zero - add ext2fs_sbcompute(), to compute dynamic values of the superblock. It is done twice in _reload() and _mountfs(), so put it in a function. - reorder the code in charge of loading the superblock: now, read the superblock, swap it directly, and then pass it to ext2fs_sbcheck(). It is similar to what ffs now does. It is better since the fields don't need to be swapped on the fly in ext2fs_sbcheck(). Tested on amd64.

1.177	05-Mar-2014	hannken	Current support for iterating over mnt_vnodelist is rudimentary. Every caller has to care about list and vnode mutexes, reference count being zero, intermediate vnode states like VI_CLEAN, VI_XLOCK, VI_MARKER and so on. Add an interface to iterate over a vnode list: void vfs_vnode_iterator_init(struct mount mp, struct vnode_iterator marker) void vfs_vnode_iterator_destroy(struct vnode_iterator marker) bool vfs_vnode_iterator_next(struct vnode_iterator marker, struct vnode vpp) vfs_vnode_iterator_next() returns either "false / vpp == NULL" when done or "true / vpp != NULL" to return the next referenced vnode from the list.

1.134	06-May-2008	ad	branches: 1.134.2; PR kern/38141 lookup/vfs_busy acquire rwlock recursively Simplify the mount locking. Remove all the crud to deal with recursion on the mount lock, and crud to deal with unmount as another weirdo lock. Hopefully this will once and for all fix the deadlocks with this. With this commit there are two locks on each mount: - krwlock_t mnt_unmounting. This is used to prevent unmount across critical sections like getnewvnode(). It's only ever read locked with rw_tryenter(), and is only ever write locked in dounmount(). A write hold can't be taken on this lock if the current LWP could hold a vnode lock. - kmutex_t mnt_updating. This is taken by threads updating the mount, for example when going r/o -> r/w, and is only present to serialize updates. In order to take this lock, a read hold must first be taken on mnt_unmounting, and the two need to be held across the operation. One effect of this change: previously if an unmount failed, we would make a half hearted attempt to back out of it gracefully, but that was unlikely to work in a lot of cases. Now while an unmount that will be aborted is in progress, new file operations within the mount will fail instead of being delayed. That is unlikely to be a problem though, because if the admin requests unmount of a file system then s(he) has made a decision to deny access to the resource.

1.91	23-Sep-2005	jmmv	Apply the NFS exports list rototill patch: - Remove all NFS related stuff from file system specific code. - Drop the vfs_checkexp hook and generalize it in the new nfs_check_export function, thus removing redundancy from all file systems. - Move all NFS export-related stuff from kern/vfs_subr.c to the new file sys/nfs/nfs_export.c. The former was becoming large and its code is always compiled, regardless of the build options. Using the latter, the code is only compiled in when NFSSERVER is enabled. While doing this, also make some functions in nfs_subs.c conditional to NFSSERVER. - Add a new command in nfssvc(2), called NFSSVC_SETEXPORTSLIST, that takes a path and a set of export entries. At the moment it can only clear the exports list or append entries, one by one, but it is done in a way that allows setting the whole set of entries atomically in the future (see the comment in mountd_set_exports_list or in doc/TODO). - Change mountd(8) to use the nfssvc(2) system call instead of mount(2) so that it becomes file system agnostic. In fact, all this whole thing was done to remove a 'XXX' block from this utility! - Change the mount, newfs and fsck userland utilities to not deal with NFS exports initialization; done internally by the kernel when initializing the NFS support for each file system. - Implement an interface for VFS (called VFS hooks) so that several kernel subsystems can run arbitrary code upon receipt of specific VFS events. At the moment, this only provides support for unmount and is used to destroy NFS exports lists from the file systems being unmounted, though it has room for extension. Thanks go to yamt@, chs@, thorpej@, wrstuden@ and others for their comments and advice in the development of this patch.
1.90	12-Sep-2005	christos	- access the ffs and ext2fs itimes functions through a pointer, so that if the filesystem is not compiled in the kernel still links. Probably a better solution is to use weak symbols. - move the filesystem-specific itime macros to the filesystem header files.

1.80	09-Jan-2005	mycroft	Whoops -- move the location of the VOP_OPEN()/VOP_CLOSE(), et al, from foo_mountfs() to foo_mount(), to match the new mountroot API. Also, for ext2fs and lfs, copy some restructuring from ffs to allow changing file system parameters without specifying the device name. (ntfs could use some more work.)
1.79	09-Jan-2005	mycroft	Rework the mountroot interface so that vfs_mountroot() opens the root device and just passes it on to the file system functions. This avoids opening and closing the device several times. Mentioned on tech-kern some time ago, IIRC. I've been running this for a long time.
1.78	02-Jan-2005	thorpej	Add the system call and VFS infrastructure for file system extended attributes. From FreeBSD.
1.77	11-Nov-2004	christos	Put the correct fragment size in struct statvfs. From Kevin Lahey.
1.76	21-Sep-2004	thorpej	Add a new VNODE_LOCKDEBUG option, which enables checks in the VOP_*() calls to ensure that the vnode lock state is as expected when the VOP call is made. Modify vnode_if.src to set the expected state according to the documenting lock table for each VOP. Modify vnode_if.sh to emit the checks. Notes: - The checks are only performed if the vnode has the VLOCKSWORK bit set. Some file systems (e.g. specfs) don't even bother with vnode locks, so of course the checks will fail. - We can't actually run with VNODE_LOCKDEBUG because there are so many vnode locking problems, not the least of which is the "use SHARED for VOP_READ()" issue, which screws things up for the entire call chain. Inspired by similar changes in OpenBSD, but implemented differently.
1.75	15-Aug-2004	mycroft	Fixing age old cruft: * Rather than using mnt_maxsymlinklen to indicate that a file systems returns d_type fields(!), add a new internal flag, IMNT_DTYPE. Add 3 new elements to ufsmount: * um_maxsymlinklen, replaces mnt_maxsymlinklen (which never should have existed in the first place). * um_dirblksiz, which tracks the current directory block size, eliminating the FS-specific checks littered throughout the code. This may be used later to make the block size variable. * um_maxfilesize, which is the maximum file size, possibly adjusted lower due to implementation issues. Sync some bug fixes from FFS into ext2fs, particularly: * ffs_lookup.c 1.21, 1.28, 1.33, 1.48 * ffs_inode.c 1.43, 1.44, 1.45, 1.66, 1.67 * ffs_vnops.c 1.84, 1.85, 1.86 Clean up some crappy pointer frobnication.
1.74	14-Aug-2004	mycroft	Add a new flag, IN_MODIFY. This is like IN_UPDATE\|IN_CHANGE, but unlike setting those flags, it does not cause the inode to be written in the periodic sync. This is used for writes to special files (devices and named pipes) and FIFOs. Do not preemptively sync updates to access times and modification times. They are now updated in the inode only opportunistically, or when the file or device is closed. (Really, it should be delayed beyond close, but this is enough to help substantially with device nodes.) And the most amusing part: Trickle sync was broken on both FFS and ext2fs, in different ways. In FFS, the periodic call to VFS_SYNC(MNT_LAZY) was still causing all file data to be synced. In ext2fs, it was causing the metadata to not be synced. We now only call VOP_UPDATE() on the node if we're doing MNT_LAZY. I've confirmed that we do in fact trickle correctly now.
1.73	05-Jul-2004	pk	Call inittodr() from main(). Let file system code set the recorded `last update' time (if any) through the new function setrootfstime().
1.72	25-May-2004	hannken	Add ffs internal snapshots. Written by Marshall Kirk McKusick for FreeBSD. - Not enabled by default. Needs kernel option FFS_SNAPSHOT. - Change parameters of ffs_blkfree. - Let the copy-on-write functions return an error so spec_strategy may fail if the copy-on-write fails. - Change genfs_lock() to use vp->v_vnlock instead of &vp->v_lock. - Add flag B_METAONLY to VOP_BALLOC to return indirect block buffer. - Add a function ffs_checkfreefile needed for snapshot creation. - Add special handling of snapshot files: Snapshots may not be opened for writing and the attributes are read-only. Use the mtime as the time this snapshot was taken. Deny mtime updates for snapshot files. - Add function transferlockers to transfer any waiting processes from one lock to another. - Add vfsop VFS_SNAPSHOT to take a snapshot and make it accessible through a vnode. - Add snapshot support to ls, fsck_ffs and dump.

1.70	20-May-2004	atatat	Explicitly call pool_init() (and pool_destroy()) when being built as an _LKM. This adds pools to the list of things that lkms must do manually because they're set up with link sets. Not that there's anything wrong with link sets, but that we need to try harder to remember that lkms are second class citizens. Of a sort.

1.64	04-Dec-2003	atatat	Dynamic sysctl. Gone are the old kern_sysctl(), cpu_sysctl(), hw_sysctl(), vfs_sysctl(), etc, routines, along with sysctl_int() et al. Now all nodes are registered with the tree, and nodes can be added (or removed) easily, and I/O to and from the tree is handled generically. Since the nodes are registered with the tree, the mapping from name to number (and back again) can now be discovered, instead of having to be hard coded. Adding new nodes to the tree is likewise much simpler -- the new infrastructure handles almost all the work for simple types, and just about anything else can be done with a small helper function. All existing nodes are where they were before (numerically speaking), so all existing consumers of sysctl information should notice no difference. PS - I'm sorry, but there's a distinct lack of documentation at the moment. I'm working on sysctl(3/8/9) right now, and I promise to watch out for buses.

1.59	29-Jun-2003	thorpej	Undo part of the ktrace/lwp changes. In particular: * Remove the "lwp " argument that was added to vget(). Turns out that nothing actually used it! Remove the "lwp " arguments that were added to VFS_ROOT(), VFS_VGET(), and VFS_FHTOVP(); all they did was pass it to vget() (which, as noted above, didn't use it). Remove all of the "lwp *" arguments to internal functions that were added just to appease the above.
1.58	28-Jun-2003	darrenr	Pass lwp pointers throughtout the kernel, as required, so that the lwpid can be inserted into ktrace records. The general change has been to replace "struct proc " with "struct lwp " in various function prototypes, pass the lwp through and use l_proc to get the process pointer when needed. Bump the kernel rev up to 1.6V
1.57	16-Apr-2003	christos	PR/1796: John Kohl: statfs misbehaves under chrooted environments. - Under chroot it displays only the visible filesystems with appropriate paths. - The statfs f_mntonname gets adjusted to contain the real path from root. - While was there, fixed a bug in ext2fs, locking problems with vfs_getfsstat(), and factored out some of the vfsop statfs() code to copy_statfs_info(). This fixes the problem where some filesystems forgot to set fsid. - Made coda look more like a normal fs.

1.55	02-Apr-2003	fvdl	Add support for UFS2. UFS2 is an enhanced FFS, adding support for 64 bit block pointers, extended attribute storage, and a few other things. This commit does not yet include the code to manipulate the extended storage (for e.g. ACLs), this will be done later. Originally written by Kirk McKusick and Network Associates Laboratories for FreeBSD.

1.52	21-Sep-2002	christos	MNT_GETARGS support
1.51	06-Sep-2002	gehenna	Merge the gehenna-devsw branch into the trunk. This merge changes the device switch tables from static array to dynamically generated by config(8). - All device switches is defined as a constant structure in device drivers. - The new grammer ``device-major'' is introduced to ``files''. device-major <prefix> char <num> [block <num>] [<rules>] - All device major numbers must be listed up in port dependent majors.<arch> by using this grammer. - Added the new naming convention. The name of the device switch must be <prefix>_[bc]devsw for auto-generation of device switch tables. - The backward compatibility of loading block/character device switch by LKM framework is broken. This is necessary to convert from block/character device major to device name in runtime and vice versa. - The restriction to assign device major by LKM is completely removed. We don't need to reserve LKM entries for dynamic loading of device switch. - In compile time, device major numbers list is packed into the kernel and the LKM framework will refer it to assign device major number dynamically.
1.50	30-Jul-2002	soren	Die, qaddr_t, die! - mnt_data in struct mount is already effectively a void *, so stop pretending otherwise.
1.49	08-Mar-2002	thorpej	branches: 1.49.6; Pool deals fairly well with physical memory shortage, but it doesn't deal with shortages of the VM maps where the backing pages are mapped (usually kmem_map). Try to deal with this: * Group all information about the backend allocator for a pool in a separate structure. The pool references this structure, rather than the individual fields. * Change the pool_init() API accordingly, and adjust all callers. * Link all pools using the same backend allocator on a list. * The backend allocator is responsible for waiting for physical memory to become available, but will still fail if it cannot callocate KVA space for the pages. If this happens, carefully drain all pools using the same backend allocator, so that some KVA space can be freed. * Change pool_reclaim() to indicate if it actually succeeded in freeing some pages, and use that information to make draining easier and more efficient. * Get rid of PR_URGENT. There was only one use of it, and it could be dealt with by the caller. From art@openbsd.org.

1.45	15-Sep-2001	chs	branches: 1.45.2; a whole bunch of changes to improve performance and robustness under load: - remove special treatment of pager_map mappings in pmaps. this is required now, since I've removed the globals that expose the address range. pager_map now uses pmap_kenter_pa() instead of pmap_enter(), so there's no longer any need to special-case it. - eliminate struct uvm_vnode by moving its fields into struct vnode. - rewrite the pageout path. the pager is now responsible for handling the high-level requests instead of only getting control after a bunch of work has already been done on its behalf. this will allow us to UBCify LFS, which needs tighter control over its pages than other filesystems do. writing a page to disk no longer requires making it read-only, which allows us to write wired pages without causing all kinds of havoc. - use a new PG_PAGEOUT flag to indicate that a page should be freed on behalf of the pagedaemon when it's unlocked. this flag is very similar to PG_RELEASED, but unlike PG_RELEASED, PG_PAGEOUT can be cleared if the pageout fails due to eg. an indirect-block buffer being locked. this allows us to remove the "version" field from struct vm_page, and together with shrinking "loan_count" from 32 bits to 16, struct vm_page is now 4 bytes smaller. - no longer use PG_RELEASED for swap-backed pages. if the page is busy because it's being paged out, we can't release the swap slot to be reallocated until that write is complete, but unlike with vnodes we don't keep a count of in-progress writes so there's no good way to know when the write is done. instead, when we need to free a busy swap-backed page, just sleep until we can get it busy ourselves. - implement a fast-path for extending writes which allows us to avoid zeroing new pages. this substantially reduces cpu usage. - encapsulate the data used by the genfs code in a struct genfs_node, which must be the first element of the filesystem-specific vnode data for filesystems which use genfs_{get,put}pages(). - eliminate many of the UVM pagerops, since they aren't needed anymore now that the pager "put" operation is a higher-level operation. - enhance the genfs code to allow NFS to use the genfs_{get,put}pages instead of a modified copy. - clean up struct vnode by removing all the fields that used to be used by the vfs_cluster.c code (which we don't use anymore with UBC). - remove kmem_object and mb_object since they were useless. instead of allocating pages to these objects, we now just allocate pages with no object. such pages are mapped in the kernel until they are freed, so we can use the mapping to find the page to free it. this allows us to remove splvm() protection in several places. The sum of all these changes improves write throughput on my decstation 5000/200 to within 1% of the rate of NetBSD 1.5 and reduces the elapsed time for "make release" of a NetBSD 1.5 source tree on my 128MB pc to 10% less than a 1.5 kernel took.
1.44	15-Sep-2001	chs	add a new VFS op, vfs_reinit, which is called when desiredvnodes is adjusted via sysctl. file systems that have hash tables which are sized based on the value of this variable now resize those hash tables using the new value. the max number of FFS softdeps is also recalculated. convert various file systems to use the <sys/queue.h> macros for their hash tables.

1.34	16-Mar-2000	jdolecek	Add new VFS op routine - vfs_done and call it on filesystem detach in vfs_detach(). vfs_done may free global filesystem's resources, typically those allocated in respective filesystem's init function. Needed so those filesystems which went in via LKM have a chance to clean after themselves before unloading. This fixes random panics when LKM for filesystem using pools was loaded and unloaded several times. For each leaf filesystem, add appropriate vfs_done routine.

The superblock and inodes (without blk addr) are byteswapped at disk read/write time, other metadatas are byteswapped when used (as they are acceeded directly in the buffer cache).

1.5	23-Oct-1997	bouyer	Uses ext2fs_vinit not ufs_vinit. In ext2fs, an inode is deleted either when mode == 0 or dtime != 0. If dtime != 0, reset others fields before using the inode, or we could end up with the wrong v_op in ext2fs_vinit. While I'm there, kill a unused variable in ext2fs_readwrite
1.4	09-Oct-1997	bouyer	branches: 1.4.2; Add byte-swapping functions (bswap16, bswap32, bswap64) to libkern. Only assembly version for i386 bswap16 and bswap32 for now (bswap64 uses bswap32). Contribution of assembly versions of these are welcome. Add byte-swapping of ext2fs metadata for big-endian systems. Tested on i386 and sparc.
1.3	17-Jul-1997	bouyer	branches: 1.3.2; Add a lock locking around inode hashing.
1.2	12-Jun-1997	mrg	remove swap configuration.
1.1	11-Jun-1997	bouyer	The ext2fs layer, based on the ffs/ufs one. Uses a few functions from sys/ufs/ufs/
1.3.2.1	14-Oct-1997	thorpej	Update marc-pcmcia branch from trunk.

1.4.2.1	23-Oct-1997	mellon	Pull rev 1.5 up from trunk
1.24.6.1	30-Nov-1999	itojun	bring in latest KAME (as of 19991130, KAME/NetBSD141) into kame branch just for reference purposes. This commit includes 1.4 -> 1.4.1 sync for kame branch. The branch does not compile at all (due to the lack of ALTQ and some other source code). Please do not try to modify the branch, this is just for referenre purposes. synchronization to latest KAME will take place on HEAD branch soon.

1.24.2.3	01-Feb-2000	he	Apply patch (requested by bouyer): Add support for ext2fs revision 1, with read-only support for the 'sparse_super' and 'filetype' options. Should fix PR#9088.
1.24.2.2	18-Oct-1999	cgd	pull up rev 1.28 from trunk (requested by wrstuden): In spec_close(), call the device's close routine with the vnode unlocked if the call might block. Force a non-blocking close if VXLOCK is set. This eliminates a potential deadlock situation, and should eliminate the dirty buffers on reboot issue.
1.24.2.1	21-Jun-1999	perry	pullup 1.24->1.25 (bouyer): zero ump->um_e2fs after malloc
1.27.2.2	27-Dec-1999	wrstuden	Pull up to last week's -current.
1.27.2.1	21-Dec-1999	wrstuden	Initial commit of recent changes to make DEV_BSIZE go away. Runs on i386, needs work on other arch's. Main kernel routines should be fine, but a number of the stand programs need help. cd, fd, ccd, wd, and sd have been updated. sd has been tested with non-512 byte block devices. vnd, raidframe, and lfs need work. Non 2**n block support is automatic for LKM's and conditional for kernels on "options NON_PO2_BLOCKS".
1.28.4.3	15-Nov-1999	fvdl	Sync with -current
1.28.4.2	03-Nov-1999	fvdl	Give ufs_ihashget an extra argument: the flags passed to vget() for locking. This way we can avoid locking against ourselves when ufs_ihashget is called during the flushing of metadata. XXX Also, comment out a VOP_FSYNC call that I think is now unneeded, and put a diagnostic printf there to check if this still happens.
1.28.4.1	19-Oct-1999	fvdl	Bring in Kirk McKusick's FFS softdep code on a branch.

1.36.2.3	14-Dec-2000	he	Pull up revision 1.39 (requested by fvdl): Improve NFS performance, possibly with as much as 100% in throughput. Please note: this implies a kernel interface change, VOP_FSYNC gains two arguments.
1.36.2.2	24-Jul-2000	jdolecek	pullup rev. 1.38 from trunk (approved by thorpej): ext2fs_reload(), ext2fs_mountfs(): do devvp locking same way as ffs this has not shown any good or bad effect, but might help narrow some problems people seen with ext2fs reload
1.36.2.1	03-Jul-2000	fvdl	pullup from trunk: Fix a "locking against myself" problem; holding ufs_hashlock across getnewvnode() could cause a recursive lock if it resulted in recycling a vnode that was using softdeps.

1.42.2.6	24-Jun-2002	nathanw	Curproc->curlwp renaming. Change uses of "curproc->l_proc" back to "curproc", which is more like the original use. Bare uses of "curproc" are now "curlwp". "curproc" is now #defined in proc.h as ((curlwp) ? (curlwp)->l_proc) : NULL) so that it is always safe to reference curproc (dereferencing curproc is another story, but that's always been true).

1.43.6.3	01-Oct-2001	fvdl	Catch up with -current.
1.43.6.2	26-Sep-2001	fvdl	* add a VCLONED vnode flag that indicates a vnode representing a cloned device. * rename REVOKEALL to REVOKEALIAS, and add a REVOKECLONE flag, to pass to VOP_REVOKE * the revoke system call will revoke all aliases, as before, but not the clones * vdevgone is called when detaching a device, so make it use REVOKECLONE to get rid of all clones as well * clean up all uses of VOP_OPEN wrt. locking. * add a few VOPS to spec_vnops that need to do something when it's a clone vnode (access and getattr) * add a copy of the vnode vattr structure of the original 'master' vnode to the specinfo of a cloned vnode. could possibly redirect getattr to the 'master' vnode, but this has issues with revoke * add a vdev_reassignvp function that disassociates a vnode from its original device, and reassociates it with the specified dev_t. to be used by cloning devices only, in case a new minor is allocated. * change all direct references in drivers to v_devcookie and v_rdev to vdev_privdata(vp) and vdev_rdev(vp). for diagnostic purposes when debugging race conditions that still exist wrt. locking and revoking vnodes. * make the locking state of a vnode consistent when passed to d_open and d_close (unlocked). locked would be better, but has some deadlock issues
1.43.6.1	18-Sep-2001	fvdl	Various changes to make cloning devices possible: * Add an extra argument (struct vnode *) to VOP_OPEN. If it is not NULL, specfs will create a cloned (aliased) vnode during the call, and return it there. The caller should release and unlock the original vnode if a new vnode was returned. The new vnode is returned locked. Add a flag field to the cdevsw and bdevsw structures. DF_CLONING indicates that it wants a new vnode for each open (XXX is there a better way? devprop?) * If a device is cloning, always call the close entry point for a VOP_CLOSE. Also, rewrite cons.c to do the right thing with vnodes. Use VOPs rather then direct device entry calls. Suggested by mycroft@ Light to moderate testing done an i386 system (arch doesn't matter though, these are MI changes).

Remove the "lwp " arguments that were added to VFS_ROOT(), VFS_VGET(), and VFS_FHTOVP(); all they did was pass it to vget() (which, as noted above, didn't use it). Remove all of the "lwp *" arguments to internal functions that were added just to appease the above.

1.60.2.1	02-Jul-2003	darrenr	Apply the aborted ktrace-lwp changes to a specific branch. This is just for others to review, I'm concerned that patch fuziness may have resulted in some errant code being generated but I'll look at that later by comparing the diff from the base to the branch with the file I attempt to apply to it. This will, at the very least, put the changes in a better context for others to review them and attempt to tinker with removing passing of 'struct lwp' through the kernel.

Don't use e2fs_inode_size in superblock on E2FS_REV0 file system. - accept only EXT2_REV0_DINODE_SIZE inodesize on -O 0 - use inodesize to get offset of inode, not struct ext2fs_dinode array Replace a magic number with a new EXT2_REV0_DINODE_SIZE macro. Use EXT2_DINODE_SIZE() to get offset of inode, not struct ext2fs_dinode array. Fix botched logic in inodesize check. Use inodesize to get offset of inode in one more place. - add a sanity check for e2fs_inode_size in readsb() - use EXT2_DINODE_SIZE() rather than sizeof(struct ext2fs_dinode) or struct ext2fs_dinode array/pointer to see e2fs_ipb and inode offsets Sort options. New sentence, new line. Sort options in usage. - unsigned -> unsigned int - remove unnecessary casts from malloc(3) and free(3) - fix a bogus indent Use "size > INT32_MAX" rather than "size >= 0x80000000U" to check 2GB limit. Add missed byteswap ops against ext2fs_dinode members. Handle 32 bit uid field on E2FS_REV1.

1.137	27-Mar-2022	christos	add a kauth vnode check for creating links
1.136	20-Oct-2021	thorpej	Overhaul of the EVFILT_VNODE kevent(2) filter: - Centralize vnode kevent handling in the VOP_() wrappers, rather than forcing each individual file system to deal with it (except VOP_RENAME(), because VOP_RENAME() is a mess and we currently have 2 different ways of handling it; at least it's reasonably well-centralized in the "new" way). - Add support for NOTE_OPEN, NOTE_CLOSE, NOTE_CLOSE_WRITE, and NOTE_READ, compatible with the same events in FreeBSD. - Track which kevent notifications clients are interested in receiving to avoid doing work for events no one cares about (avoiding, e.g. taking locks and traversing the klist to send a NOTE_WRITE when someone is merely watching for a file to be deleted, for example). In support of the above: - Add support in vnode_if.sh for specifying PRE- and POST-op handlers, to be invoked before and after vop_pre() and vop_post(), respectively. Basic idea from FreeBSD, but implemented differently. - Add support in vnode_if.sh for specifying CONTEXT fields in the vop__args structures. These context fields are used to convey information between the file system VOP function and the VOP wrapper, but do not occupy an argument slot in the VOP_*() call itself. These context fields are initialized and subsequently interpreted by PRE- and POST-op handlers. - Version VOP_REMOVE(), uses the a context field for the file system to report back the resulting link count of the target vnode. Return this in tmpfs, udf, nfs, chfs, ext2fs, lfs, and ufs. NetBSD 9.99.92.
1.135	18-Jul-2021	dholland	Abolish all the silly indirection macros for initializing vnode ops tables. These are things of the form #define foofs_op genfs_op, or #define foofs_op genfs_eopnotsupp, or similar. They serve no purpose besides obfuscation, and have gotten cutpasted all over everywhere.
1.134	18-Jul-2021	dholland	Use macros for the canned parts of device and fifo vnode op tables. Add GENFS_SPECOP_ENTRIES and GENFS_FIFOOP_ENTRIES macros that contain the portion of the vnode ops table declaration that is (conservatively) the same in every fs. Use these in every fs that supports devices and/or fifos with separate ops tables. Note that ptyfs works differently (it has one type of vnode with open-coded dispatch to the specfs code, which I haven't changed in this commit) and rump/librump/rumpvfs/rumpfs.c has an indirect dynamic dispatch that already does more or less the same thing, which I also haven't changed. Also note that this anticipates a few bits in the next changeset here and there, and adds missing but unreachable calls in some cases (e.g. most fses weren't defining whiteout on devices and fifos, but it isn't reachable there), and it changes parsepath on devices and fifos to genfs_badop from genfs_parsepath (but it's not reachable there either). It appears that devices in kernfs were missing kqfilter, so it's possible that if you try to use kqueue on /kern/rootdev that it'll explode. And finally note that the ops declaration tables aren't order-dependent. (Other than vop_default_desc has to come first.) Otherwise this wouldn't work.
1.133	29-Jun-2021	dholland	- Add a new vnode op: VOP_PARSEPATH. - Move namei_getcomponent to genfs_vnops.c and call it genfs_parsepath. - Add a parsepath entry to every vnode ops table. VOP_PARSEPATH takes a directory vnode to be searched and a complete following path and chooses how much of that path to consume. To begin with, all parsepath calls are genfs_parsepath, which locates the first '/' as always. Note that the call doesn't take the whole struct componentname, only the string. The other bits of struct componentname should not be needed and there's no reason to cause potential complications by exposing them.

1.128	28-May-2017	hannken	branches: 1.128.8; 1.128.10; Change ext2fs to use vcache_new like we did for ffs: - Change ext2fs_valloc to return an inode number. - Make ext2fs_makeinode private to ext2fs_vnops.c and pass vattr instead of mode.
1.127	26-May-2017	riastradh	Make VOP_RECLAIM do the last unlock of the vnode. VOP_RECLAIM naturally has exclusive access to the vnode, so having it locked on entry is not strictly necessary -- but it means if there are any final operations that must be done on the vnode, such as ffs_update, requiring exclusive access to it, we can now kassert that the vnode is locked in those operations. We can't just have the caller release the last lock because some file systems don't use genfs_lock, and require the vnode to remain valid for VOP_UNLOCK to work, notably unionfs.
1.126	26-Apr-2017	riastradh	Change VOP_REMOVE and VOP_RMDIR to preserve lock/ref on dvp. No change to vp -- the plan is to replace the node by the componentname in the vop parameters, and let all directory vops do lookups internally.

1.116	27-Mar-2015	riastradh	Disentangle buffer-cached I/O from page-cached I/O in UFS. Page-cached I/O is used for regular files, and is initiated by VFS users such as userland and NFS. Buffer-cached I/O is used for directories and symlinks, and is issued only internally by UFS. New UFS routine ufs_bufio replaces vn_rdwr for internal use. ufs_bufio is implemented by new UFS operations uo_bufrd/uo_bufwr, which sit in ufs_readwrite.c alongside the VOP_READ/VOP_WRITE implementations. I preserved the code as much as possible and will leave further simplification for future commits. I kept the ulfs_readwrite.c copypasta close to ufs_readwrite.c in case we ever want to merge them back; likewise ext2fs_readwrite.c. No externally visible semantic change. All atf fs tests still pass.

The device ones call spec_fallocate (which is also genfs_eopnotsupp) and spec_fdiscard, which dispatches to the device-level op. The fifo ones all call vn_fifo_bypass, which also ends up being EOPNOTSUPP.

1.107	18-Mar-2013	plunky	branches: 1.107.6; C99 section 6.7.2.3 (Tags) Note 3 states that: A type specifier of the form enum identifier without an enumerator list shall only appear after the type it specifies is complete. which means that we cannot pass an "enum vtype" argument to kauth_access_action() without fully specifying the type first. Unfortunately there is a complicated include file loop which makes that difficult, so convert this minimal function into a macro (and capitalize it). (ok elad@)
1.106	22-Jan-2013	dholland	Stuff UFS_ in front of a few of ufs's symbols to reduce namespace pollution. Specifically: ROOTINO -> UFS_ROOTINO WINO -> UFS_WINO NXADDR -> UFS_NXADDR NDADDR -> UFS_NDADDR NIADDR -> UFS_NIADDR MAXSYMLINKLEN -> UFS_MAXSYMLINKLEN MAXSYMLINKLEN_UFS[12] -> UFS[12]_MAXSYMLINKLEN (for consistency) Sort out ext2fs's misuse of NDADDR and NIADDR; fortunately, these have the same values in ext2fs and ffs. No functional change intended.

1.100	12-Jul-2011	dholland	branches: 1.100.2; Pass the ufs_lookup_results pointer around instead of fetching it from the inode in the guts of ufs. Now, in VOPs where i_crap is used it is used (directly) only immediately on entry to the VOP call and then passed around by reference. Except for rename, which needs explicit sorting out. The code in ufs_wapbl_rename is unchanged in behavior but I'm increasingly inclined to think it's wrong.

Check all call sites to make sure that SAVESTART wasn't set while calling relookup(); if it was, adjust the refcount behavior. Remove related references to SAVESTART. The only code that was reaching the extra ref was msdosfs_rename, where the refcount behavior was already fairly broken and/or gross; repair it. Add a dummy 4th argument to relookup to make sure code that hasn't been inspected won't compile. (This will go away next time the relookup semantics change, which they will.)
1.96	30-Nov-2010	dholland	Abolish the SAVENAME and HASBUF flags. There is now always a buffer, so the path in a struct componentname is now always valid during VOP calls.

(For now a pnbuf pointer appears in struct nameidata, to support certain unclean things that haven't been fixed yet, but it will be going away in the future.) This removes the need for the SAVENAME and HASBUF namei flags.

1.70	09-Dec-2006	chs	a smorgasbord of improvements to vnode locking and path lookup: - LOCKPARENT is no longer relevant for lookup(), relookup() or VOP_LOOKUP(). these now always return the parent vnode locked. namei() works as before. lookup() and various other paths no longer acquire vnode locks in the wrong order via vrele(). fixes PR 32535. as a nice side effect, path lookup is also up to 25% faster. - the above allows us to get rid of PDIRUNLOCK. - also get rid of WANTPARENT (just use LOCKPARENT and unlock it). - remove an assumption in layer_node_find() that all file systems implement a recursive VOP_LOCK() (unionfs doesn't). - require that all file systems supply vfs_vptofh and vfs_fhtovp routines. fill in eopnotsupp() for file systems that don't support being exported and remove the checks for NULL. (layerfs calls these without checking.) - in union_lookup1(), don't change refcounts in the ISDOTDOT case, just adjust which vnode is locked. fixes PR 33374. - apply fixes for ufs_rename() from ufs_vnops.c rev. 1.61 to ext2fs_rename().

1.57	21-Sep-2004	thorpej	branches: 1.57.4; 1.57.6; Add a new VNODE_LOCKDEBUG option, which enables checks in the VOP_*() calls to ensure that the vnode lock state is as expected when the VOP call is made. Modify vnode_if.src to set the expected state according to the documenting lock table for each VOP. Modify vnode_if.sh to emit the checks. Notes: - The checks are only performed if the vnode has the VLOCKSWORK bit set. Some file systems (e.g. specfs) don't even bother with vnode locks, so of course the checks will fail. - We can't actually run with VNODE_LOCKDEBUG because there are so many vnode locking problems, not the least of which is the "use SHARED for VOP_READ()" issue, which screws things up for the entire call chain. Inspired by similar changes in OpenBSD, but implemented differently.

Add 3 new elements to ufsmount: * um_maxsymlinklen, replaces mnt_maxsymlinklen (which never should have existed in the first place). * um_dirblksiz, which tracks the current directory block size, eliminating the FS-specific checks littered throughout the code. This may be used later to make the block size variable. * um_maxfilesize, which is the maximum file size, possibly adjusted lower due to implementation issues. Sync some bug fixes from FFS into ext2fs, particularly: * ffs_lookup.c 1.21, 1.28, 1.33, 1.48 * ffs_inode.c 1.43, 1.44, 1.45, 1.66, 1.67 * ffs_vnops.c 1.84, 1.85, 1.86 Clean up some crappy pointer frobnication.

(Note: This happens at reboot/shutdown time because all file systems are unmounted.) Also, for IN_MODIFY, use IN_ACCESSED, not IN_MODIFIED; otherwise "ls -l" of your device node or FIFO would cause the time stamps to get written too quickly.

Remove the "lwp " arguments that were added to VFS_ROOT(), VFS_VGET(), and VFS_FHTOVP(); all they did was pass it to vget() (which, as noted above, didn't use it).

1.38	22-Sep-2001	sommerfeld	branches: 1.38.2; Add fifo_putpages() placebo so that the vnode's uobj is unlocked.
1.37	15-Sep-2001	chs	a whole bunch of changes to improve performance and robustness under load: - remove special treatment of pager_map mappings in pmaps. this is required now, since I've removed the globals that expose the address range. pager_map now uses pmap_kenter_pa() instead of pmap_enter(), so there's no longer any need to special-case it. - eliminate struct uvm_vnode by moving its fields into struct vnode. - rewrite the pageout path. the pager is now responsible for handling the high-level requests instead of only getting control after a bunch of work has already been done on its behalf. this will allow us to UBCify LFS, which needs tighter control over its pages than other filesystems do. writing a page to disk no longer requires making it read-only, which allows us to write wired pages without causing all kinds of havoc. - use a new PG_PAGEOUT flag to indicate that a page should be freed on behalf of the pagedaemon when it's unlocked. this flag is very similar to PG_RELEASED, but unlike PG_RELEASED, PG_PAGEOUT can be cleared if the pageout fails due to eg. an indirect-block buffer being locked. this allows us to remove the "version" field from struct vm_page, and together with shrinking "loan_count" from 32 bits to 16, struct vm_page is now 4 bytes smaller. - no longer use PG_RELEASED for swap-backed pages. if the page is busy because it's being paged out, we can't release the swap slot to be reallocated until that write is complete, but unlike with vnodes we don't keep a count of in-progress writes so there's no good way to know when the write is done. instead, when we need to free a busy swap-backed page, just sleep until we can get it busy ourselves. - implement a fast-path for extending writes which allows us to avoid zeroing new pages. this substantially reduces cpu usage. - encapsulate the data used by the genfs code in a struct genfs_node, which must be the first element of the filesystem-specific vnode data for filesystems which use genfs_{get,put}pages(). - eliminate many of the UVM pagerops, since they aren't needed anymore now that the pager "put" operation is a higher-level operation. - enhance the genfs code to allow NFS to use the genfs_{get,put}pages instead of a modified copy. - clean up struct vnode by removing all the fields that used to be used by the vfs_cluster.c code (which we don't use anymore with UBC). - remove kmem_object and mb_object since they were useless. instead of allocating pages to these objects, we now just allocate pages with no object. such pages are mapped in the kernel until they are freed, so we can use the mapping to find the page to free it. this allows us to remove splvm() protection in several places. The sum of all these changes improves write throughput on my decstation 5000/200 to within 1% of the rate of NetBSD 1.5 and reduces the elapsed time for "make release" of a NetBSD 1.5 source tree on my 128MB pc to 10% less than a 1.5 kernel took.

1.26	13-May-2000	perseant	branches: 1.26.4; Change the sementics of the last parameter from a boolean ("waitfor") to a set of flags ("flags"). Two flags are defined, UPDATE_WAIT and UPDATE_DIROP. Under the old semantics, VOP_UPDATE would block if waitfor were set, under the assumption that directory operations should be done synchronously. At least LFS and FFS+softdep do not make this assumption; FFS+softdep got around the problem by enclosing all relevant calls to VOP_UPDATE in a "if(!DOINGSOFTDEP(vp))", while LFS simply ignored waitfor, one of the reasons why NFS-serving an LFS filesystem did not work properly. Under the new semantics, the UPDATE_DIROP flag is a hint to the fs-specific update routine that the call comes from a dirop routine, and should be wait for, or not, accordingly. Closes PR#8996.

1.26.4.2	06-Apr-2001	he	Pull up revision 1.33 (requested by wrstuden): Explicitly VOP_UNLOCK before setting v_op to spec_vnode_ops_p. Works around a lock leak and eventual kernel panic.
1.26.4.1	30-Jul-2000	jdolecek	Pullup from trunk (approved by thorpej): Change lf_advlock() to: int lf_advlock (struct vop_advlock_args , struct lockf *, off_t) This matches it's usage. Change inspired by FreeBSD, though we use off_t instead u_quad_t as the last argument. sys/lockf.h rev. 1.9 msdosfs/msdosfs_vnops.c rev. 1.99 kern/vfs_lockf.c rev. 1.17 miscfs/specfs/spec_vnops.c rev. 1.49 nfs/nfs_vnops.c rev. 1.115 ufs/ext2fs/ext2fs_vnops.c rev. 1.28 ufs/ufs/ufs_vnops.c rev. 1.72

1.33.4.6	26-Sep-2002	jdolecek	add support for kevents - sprikle VN_KNOTE() and add genfs_kqfilter() to vnode ops; basically same thing as in ufs_readwrite.c and ufs_vnops.c
1.33.4.5	23-Sep-2002	jdolecek	add spec kqfilter vnode op
1.33.4.4	22-Sep-2002	jdolecek	add fifo_kqfilter() to fifo ops, to switch on support for kevents
1.33.4.3	10-Jan-2002	thorpej	Sync kqueue branch with -current.

1.36.2.2	01-Oct-2001	fvdl	Catch up with -current.
1.36.2.1	18-Sep-2001	fvdl	Various changes to make cloning devices possible: * Add an extra argument (struct vnode *) to VOP_OPEN. If it is not NULL, specfs will create a cloned (aliased) vnode during the call, and return it there. The caller should release and unlock the original vnode if a new vnode was returned. The new vnode is returned locked. Add a flag field to the cdevsw and bdevsw structures. DF_CLONING indicates that it wants a new vnode for each open (XXX is there a better way? devprop?) * If a device is cloning, always call the close entry point for a VOP_CLOSE. Also, rewrite cons.c to do the right thing with vnodes. Use VOPs rather then direct device entry calls. Suggested by mycroft@ Light to moderate testing done an i386 system (arch doesn't matter though, these are MI changes).
1.38.2.1	12-Nov-2001	thorpej	Sync the thorpej-mips-cache branch with -current.

1.48.2.4	25-Aug-2004	skrll	Sync with HEAD.
1.48.2.3	24-Aug-2004	skrll	Undo part of the ktrace/lwp changes. In particular: * Remove the "lwp " argument that was added to vget(). Turns out that nothing actually used it! Remove the "lwp " arguments that were added to VFS_ROOT(), VFS_VGET(), and VFS_FHTOVP(); all they did was pass it to vget() (which, as noted above, didn't use it). Remove all of the "lwp *" arguments to internal functions that were added just to appease the above.
1.48.2.2	03-Aug-2004	skrll	Sync with HEAD
1.48.2.1	02-Jul-2003	darrenr	Apply the aborted ktrace-lwp changes to a specific branch. This is just for others to review, I'm concerned that patch fuziness may have resulted in some errant code being generated but I'll look at that later by comparing the diff from the base to the branch with the file I attempt to apply to it. This will, at the very least, put the changes in a better context for others to review them and attempt to tinker with removing passing of 'struct lwp' through the kernel.
1.52.2.1	23-May-2004	grant	Pull up revision 1.53 (requested by kleink in ticket #379): POSIX: Permit a process without the appropriate privilege to change a file's group ID to its effective gid, in addition to the presently permitted set of supplementary gids.

1.4	16-Apr-2020	rin	Revert previous for now: http://mail-index.netbsd.org/source-changes/2020/04/16/msg116278.html The reasoning turned out to be wrong; __KERNEL_RCSID() in header files does not overwrite RCSID in main source files. The real problem is that it inserts its RCSID into every object files. However, it can be still useful even if heavily duplicated.
1.3	16-Apr-2020	rin	Stop using __KERNEL_RCSID() in header files; it confuses ident(1) by overwriting RCSID in main source files. XXX The first argument of __KERNEL_RCSID() is neglected for ELF. If we wish to have RCSID of header files in kernel binary, we need something like __FBSDID() macro in FreeBSD.
