joerg | Avoid common symbols for fsck_lfs.
|
1.42 |
| 01-Sep-2015 |
dholland | branches: 1.42.16; Make the inode fields in the 64-bit superblock 64 bits wide. Reasoning as before.
Note that I am not going through and checking for 64->32 truncations in inode numbers; I'm sure there are quite a few, but that's a project for later.

1.41 |
| 23-Aug-2015 |
christos | swap the formats too, not just the args.
|
1.40 |
| 23-Aug-2015 |
dholland | Fix reversed arguments to a print. nice and confusing...
|
1.39 |
| 12-Aug-2015 |
dholland | Add IFILE32 and IFILE64 structures for the on-disk ifile entries. Add and use accessors. There are also a bunch of places that cast and I hope I've found them all...
|
1.38 |
| 12-Aug-2015 |
dholland | Make 32-bit and 64-bit versions of CLEANERINFO.
XXX: while this is written to disk, it seems like much of it would XXX: be better set up as a commpage shared with the cleaner.
|
1.37 |
| 28-Jul-2015 |
dholland | Add a new lfs header file: lfs_accessors.h.
This contains all the accessor functions and macros out of lfs.h. Add an include of lfs_accessors.h after all uses of lfs.h... except for code that wants to define its own struct lfs-alike that the accessors are supposed to play along with. For these, set STRUCT_LFS and include lfs_accessors.h after the necessary structure has been defined, so that lfs_accessors.h can emit functions in terms of it.
|
1.36 |
| 24-Jul-2015 |
dholland | Switch to accessor functions for elements of the LFS on-disk superblock. This will allow switching between 32/64 bit forms on the fly; it will also allow handling LFS_EI reasonably tidily. (That currently doesn't work on the superblock.)
It also gets rid of cpp abuse in the form of fake structure member macros.
Also, instead of doing sleep/wakeup on &lfs_avail and &lfs_nextseg inside the on-disk superblock, add extra elements to the in-memory struct lfs for this. (XXX: these should be changed to condvars, but not right now)
XXX: this migrates a structure needed by the lfs code in libsa (struct salfs) into lfs.h, where it doesn't belong, but for the time being this is necessary in order to allow the accessors (and the various lfs macros and other goop that relies on them) to compile.
|
1.35 |
| 08-Jun-2013 |
dholland | Tidy up the LFS userland build hacks. Don't use -I${NETBSDSRCDIR}/sys; don't include files other than the exported LFS headers, which are lfs.h, lfs_inode.h, and (for now) lfs_extern.h.
|
1.34 |
| 06-Jun-2013 |
dholland | Cleanups and hacks to make lfs userland stuff build: - lfs_cksum.c doesn't actually need ulfs_inode.h any more. - neither does lfs_itimes.c. - add hacks to fsck_lfs to make it compile. - add hacks to newfs_lfs to make it compile. - fix warning in ulfs_quota.c when quotas are fully disabled (as I guess is happening with the rumpity version)
XXX: This commit adds -I${NETBSDSRCDIR}/sys to the Makefiles for XXX: fsck_lfs, newfs_lfs, and lfs_cleanerd. This needs to be cleaned XXX: up ASAP; but I consider this less problematic in the short term XXX: than spewing ulfs_*.h into /usr/include.
|

| 06-Jun-2013 |
dholland | ufs -> ulfs for fsck_lfs.
|
1.32 |
| 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.

1.31 |
| 28-Apr-2008 |
martin | branches: 1.31.20; 1.31.26; Remove clause 3 and 4 from TNF licenses
|
1.30 |
| 08-Oct-2007 |
ad | branches: 1.30.8; 1.30.10; Give brelse() a second argument so that it matches the kernel. fsck_lfs now compiles again.
|
1.29 |
| 09-Nov-2006 |
christos | branches: 1.29.8; Fix malloc/realloc/calloc issues: always check and exit, use EEXIT instead of 8.
|
1.28 |
| 18-Jul-2006 |
perseant | Various improvements to fsck_lfs, to wit:
* Add lfs_balloc capability to the lfs library. * Extend the Ifile if we run out of free inodes when creating lost+found. * Don't roll forward if we have allocated a lost+found, to avoid conflicts when adding new files in roll-forward. * Make some messages slightly more verbose (e.g. include inode number, and use pwarn() instead of printf() so the messages include the device name when preening). * Change superblock detection/avoidance to use the offset table in the primary superblock, rather than looking at the contents. * Be more verbose about various operations when passed the -d flag, especially roll-forward. * Be more careful about dirops during roll forward, since the cleaner can sometimes write blocks from dirop vnodes. Detect and avoid this problem. * Always check the free list, even if given -i; if we're going to write it we have to check it first. * Mark inodes dirty when blocks are found during roll forward, so the inodes are written with the new block locations. * Update size of inodes if blocks beyond EOF are found during roll forward. * Fix segment accounting for blocks and inodes found during roll forward. * Report statistics on roll forward: how many new/deleted/moved files and how many updated blocks (or "nothing new"). * Don't care if the device being checked is really a device, if we have been passed the -f flag (to facilitate automated testing). * When writing to the disk, use the current time in the segment headers rathern than time 0. * When passed the -i flag, locate the partial segment containing the Ifile inode and use that to calculate lfs_offset, lfs_curseg, lfs_nextseg. (Again for automated testing.)
|
1.27 |
| 17-Apr-2006 |
perseant | Remove the free list ordering/disordering code, since the kernel now keeps the list in order (ordering it on mount).
Regularize error messages: these are now all in ALL CAPS, with all hex numbers (not reported in caps) prefixed by 0x. (The non-fsck-specific messages are an exception to this all-caps rule.)
|
1.26 |
| 17-Mar-2006 |
perseant | Make it compile again.
|
1.25 |
| 17-Mar-2006 |
rumble | Check for allocation failures in malloc, calloc, realloc, asprintf, and vasprintf and try to handle them.
|
1.24 |
| 13-Sep-2005 |
christos | rename lfs.h to lfs_user.h so that it does not conflict.
|
1.23 |
| 20-Aug-2005 |
kent | fix a compilation problem on LP64
|
1.22 |
| 19-Aug-2005 |
christos | 64 bit inode changes
|
1.21 |
| 08-Jun-2005 |
perseant | Use the correct method to create a new inode, when we allocate lost+found.
Correct uninitialized variable issues in pass6.c and dir.c (PR#30411 and PR#30394, respectively).
|
1.20 |
| 11-Apr-2005 |
perseant | Be more efficient with the hash tables for the buffer and vnode caches.
Note that roll-forward can add more inodes to the filesystem; don't overflow the tables but reallocate them.
|
1.19 |
| 25-Mar-2005 |
perseant | Make fsck_lfs optimize the inode free list, if it appears to have become too disordered. This should improve file creation speed on aged filesystems. Include code to disorder the list for debugging purposes, though this is of course not compiled in by default.
|
1.18 |
| 26-Feb-2005 |
perseant | branches: 1.18.2; Various minor LFS improvements:
* Extend the lfs library from fsck_lfs(8) so that it can be used with a not-yet-existent LFS. Make newfs_lfs(8) use this library, so it can create LFSs whose Ifile is larger than one segment. * Make newfs_lfs(8) use strsuftoi64() for its arguments, a la newfs(8). * Make fsck_lfs(8) respect the "file system is clean" flag. * Don't let fsck_lfs(8) think it has dirty blocks when invoked with the -n flag.

1.16 |
| 07-Aug-2003 |
agc | branches: 1.16.4; Move UCB-licensed code from 4-clause to 3-clause licence.
Patches provided by Joel Baker in PR 22308, verified by myself.
|
1.15 |
| 31-Mar-2003 |
perseant | Check inode free list tail pointer as well as head pointer, and write both into the CLEANERINFO block of the Ifile as well as into the superblock. Make preen update both superblocks.
|
1.14 |
| 28-Mar-2003 |
perseant | Add working writing ability to fsck_lfs, including roll-forward, based on a partial-segment writer ported from the kernel.
|
1.13 |
| 17-Feb-2003 |
perseant | Add code to UBCify LFS. This is still behind "#ifdef LFS_UBC" for now (there are still some details to work out) but expect that to go away soon. To support these basic changes (creation of lfs_putpages, lfs_gop_write, mods to lfs_balloc) several other changes were made, to wit:
* Create a writer daemon kernel thread whose purpose is to handle page writes for the pagedaemon, but which also takes over some of the functions of lfs_check(). This thread is started the first time an LFS is mounted.
* Add a "flags" parameter to GOP_SIZE. Current values are GOP_SIZE_READ, meaning that the call should return the size of the in-core version of the file, and GOP_SIZE_WRITE, meaning that it should return the on-disk size. One of GOP_SIZE_READ or GOP_SIZE_WRITE must be specified.
* Instead of using malloc(...M_WAITOK) for everything, reserve enough resources to get by and use malloc(...M_NOWAIT), using the reserves if necessary. Use the pool subsystem for structures small enough that this is feasible. This also obsoletes LFS_THROTTLE.
And a few that are not strictly necessary:
* Moves the LFS inode extensions off onto a separately allocated structure; getting closer to LFS as an LKM. "Welcome to 1.6O."
* Unified GOP_ALLOC between FFS and LFS.
* Update LFS copyright headers to correct values.
* Actually cast to unsigned in lfs_shellsort, like the comment says.
* Keep track of which segments were empty before the previous checkpoint; any segments that pass two checkpoints both dirty and empty can be summarily cleaned. Do this. Right now lfs_segclean still works, but this should be turned into an effectless compatibility syscall.
|
1.12 |
| 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.
|
1.11 |
| 04-Feb-2002 |
perseant | Use the correct size for inode blocks. This caused false data checksum mispatches to be reported on v2 filesystems.
|
1.10 |
| 02-Nov-2001 |
lukem | fix -Wshadow warning
|
1.9 |
| 13-Jul-2001 |
perseant | Merge the short-lived perseant-lfsv2 branch into the trunk.
Kernels and tools understand both v1 and v2 filesystems; newfs_lfs generates v2 by default. Changes for the v2 layout include:
- Segments of non-PO2 size and arbitrary block offset, so these can be matched to convenient physical characteristics of the partition (e.g., stripe or track size and offset).
- Address by fragment instead of by disk sector, paving the way for non-512-byte-sector devices. In theory fragments can be as large as you like, though in reality they must be smaller than MAXBSIZE in size.
- Use serial number and filesystem identifier to ensure that roll-forward doesn't get old data and think it's new. Roll-forward is enabled for v2 filesystems, though not for v1 filesystems by default.
- The inode free list is now a tailq, paving the way for undelete (undelete is not yet implemented, but can be without further non-backwards-compatible changes to disk structures).
- Inode atime information is kept in the Ifile, instead of on the inode; that is, the inode is never written *just* because atime was changed. Because of this the inodes remain near the file data on the disk, rather than wandering all over as the disk is read repeatedly. This speeds up repeated reads by a small but noticeable amount.
Other changes of note include:
- The ifile written by newfs_lfs can now be of arbitrary length, it is no longer restricted to a single indirect block.
- Fixed an old bug where ctime was changed every time a vnode was created. I need to look more closely to make sure that the times are only updated during write(2) and friends, not after-the-fact during a segment write, and certainly not by the cleaner.

1.8 |
| 05-Jan-2001 |
lukem | branches: 1.8.2; use %ll_ instead of the less standard %q_
|
1.7 |
| 14-Jun-2000 |
perseant | Add "-i" flag to specify the location of the index file inode, to examine alternate checkpoints. Regularize usage of maxino. Remove olf debugging cruft.
|
1.6 |
| 30-May-2000 |
perseant | Check for cycles in the inode free list, and for free inodes not on the free list.
|
1.5 |
| 23-May-2000 |
perseant | branches: 1.5.2; Convert to NetBSD source code style
|
1.4 |
| 16-May-2000 |
perseant | fsck_lfs can now write to the filesystem, allowing it to correct most (though still not all) errors in a damaged lfs. Segment byte accounting is corrected in pass 5. "fsck_lfs -p" will do a partial roll-forward, verifying the checkpoint from the newer superblock. fscknames[] is updated so that fsck knows about fsck_lfs.

perseant | Initial checkin of fsck_lfs. This version cannot do any repair (-p flag does nothing, and one of -p or -n is required) but can be useful as a diagnostic tool.
|
1.5.2.1 |
| 22-Jun-2000 |
minoura | Sync w/ netbsd-1-5-base.
|
1.8.2.2 |
| 02-Jul-2001 |
perseant | Change disk addressing unit to be the fragment, instead of the disk sector. All quantities in the superblock, inodes, indirect blocks, etc. refer now to this abstract unit (called "fsb" as it is in FFS) instead of disk sectors; as a consequence segment summary blocks have to be multiples of a fragment in size. In v1 filesystems, compatibility code ensures that 1 fsb == 1 sector, regardless of fragment size.
Fragments can now range in size between 512 and 32k; in the event that LFS_LABELPAD (8k) is smaller than the disk address unit size, an extra proto-superblock is kept at 8k from the beginning of the disk, to be used *only* to locate the real superblocks. (Not all of the userland knows about this yet.)
Almost all of this was done not by me, but by joff.
|
1.8.2.1 |
| 27-Jun-2001 |
perseant | Import of what I've been calling "LFSv2", that is, LFS with some features added that require changes to the on-disk data structures. These include:
- 64-bit time in everything but inodes - User-specified segment offset, and segment size no longer restricted to PO2. - Serial number on segment summaries in addition to timestamp, and a new volume identifier, to make roll-forward feasible without fear of finding old data and thinking it was new.
Although I think this version works at least as well as what's on the trunk, we're not done yet; hence this commit is going in on a branch and not on the trunk. Enhancements that are not here yet include fragment addressing, like FFS does, instead of block addressing.

Various minor LFS improvements.
Kernel:
* Note when lfs_putpages(9) thinks it is not going to be writing any pages before calling genfs_putpages(9). This prevents a situation in which blocks can be queued for writing without a segment header. * Correct computation of NRESERVE(), though it is still a gross overestimate in most cases. Note that if NRESERVE() is too high, it may be impossible to create files on the filesystem. We catch this case on filesystem mount and refuse to mount r/w. * Allow filesystems to be mounted whose block size is == MAXBSIZE. * Somewhere along the line, ufs_bmaparray(9) started mangling UNWRITTEN entries in indirect blocks again, triggering a failed assertion "daddr <= LFS_MAX_DADDR". Explicitly convert to and from int32_t to correct this. Should fix PR #29045. * Add a high-water mark for the number of dirty pages any given LFS can hold before triggering a flush. This is settable by sysctl, but off (zero) by default. * Be more careful about the MAX_BYTES and MAX_BUFS computations so we shouldn't see "please increase to at least zero" messages. * Note that VBLK and VCHR vnodes can have nonzero values in di_db[0] even though their v_size == 0. Don't panic when we see this. Fixes PR #26680. * Change lfs_bfree to a signed quantity. The manner in which it is processed before being passed to the cleaner means that sometimes it may drop below zero, and the cleaner must be aware of this. * Never report bfree < 0 (or higher than lfs_dsize) through lfs_statfs(9). This prevents df(1) from ever telling us that our full filesystems have 16TB free. * Account space allocated through lfs_balloc(9) that does not have associated buffer headers, so that the pagedaemon doesn't run us out of segments. * Return ENOSPC from lfs_balloc(9) when bfree drops to zero. * Address a deadlock in lfs_bmapv/lfs_markv when the filesystem is being unmounted. Because vfs_busy() is a shared lock, and lfs_bmapv/lfs_markv mark the filesystem vfs_busy(), the cleaner can be holding the lock that umount() is blocking on, then try to vfs_busy() again in getnewvnode().
cleaner:
* Adapt lfs_cleanerd to use the fcntl call to get the Ifile filehandle, so it need not be in the namespace. * Make lfs_cleanerd be more careful when there are very few available segments. * Make lfs_cleanerd less verbose when the filesystem is unmounted.
newfs_lfs, fsck_lfs, and regression:
* Extend the lfs library from fsck_lfs(8) so that it can be used with a not-yet-existent LFS. Make newfs_lfs(8) use this library, so it can create LFSs whose Ifile is larger than one segment. Addresses PR #11110. * Make newfs_lfs(8) use strsuftoi64() for its arguments, a la newfs(8). * Make fsck_lfs(8) respect the "file system is clean" flag. * Don't let fsck_lfs(8) think it has dirty blocks when invoked with the -n flag. * Remove the Ifile from the filesystem namespace. The cleaner now uses a fcntl call on the root inode to find the Ifile filehandle. (As a side-effect, addresses PR #29144.)
