joerg | Avoid common symbols for fsck_lfs.

dholland | branches: 1.46.16;
Add 64-bit directory entry structures, and adjust accessors accordingly.
The LFS64 directory entry has a 64-bit inode number. This is stored as
two 32-bit values to avoid inducing 64-bit alignment requirements.
The exposed type for manipulating directory entries is now
LFS_DIRHEADER, following the same convention as e.g. IFILE and SEGUSE.
(But with LFS_ on it, because.)
|
| 1.45 |
| 21-Sep-2015 |
dholland | Oops; LFS_DIRECTSIZ() is going to need the fs as an argument.
Also, it turns out that dirhash needs a compile-time-constant version
of LFS_DIRECTSIZ(LFS_MAXNAMLEN+1), independent of 64-vs-32, so create
LFS_MAXDIRENTRYSIZE for this. Sigh.
|
| 1.44 |
| 20-Sep-2015 |
dholland | Clean up struct lfs_dirtemplate.
|
| 1.43 |
| 15-Sep-2015 |
dholland | Pass around struct lfs_dirheader instead of struct lfs_direct.
|
| 1.42 |
| 15-Sep-2015 |
dholland | Add an accessor function for directory names.
|
| 1.41 |
| 15-Sep-2015 |
dholland | Add a function lfs_copydirname() to copy directory names in place; use
it in place of (variously) memcpy and strlcpy. (The latter isn't even
correct; was probably changed blindly from strncpy at some point.)
The new function zeroes the padding in the directory entry instead of
leaving trash behind.
|
| 1.40 |
| 15-Sep-2015 |
dholland | Tidyups/fixes preparatory to making d_name[] in struct lfs_direct size
0 instead of size LFS_MAXNAMLEN+1, and preparatory to having accessor
functions for d_name. In particular, don't create prototype entries
and copy them, and access the name field only for directory structures
that are in buffers with space for the name to exist.
|
| 1.39 |
| 15-Sep-2015 |
dholland | Add and use accessor functions for more of the directory entry fields.
|
| 1.38 |
| 01-Sep-2015 |
dholland | Add new accessors for the d_type and d_namlen fields of struct lfs_direct.
Napalm the old byteswap access logic for these.
|
| 1.37 |
| 01-Sep-2015 |
dholland | Use the lfs dinode accessors in place of the ufs-derived ones.
(Mostly.)
The ufs-derived ones are fake structure member macros, which are gross
and not very safe. Also, it seems that a lot of places in the lfs code
were using the ffsv1 branch of them unconditionally, and this way it's
guaranteed all those places have been updated.
Found while doing this: for non-devices, have getattr produce NODEV
in the rdev field instead of leaking the address of the first direct
block.
|
| 1.36 |
| 12-Aug-2015 |
dholland | Hack up dinode usage to be 64 vs. 32 as needed. Part 1.
(This part changes the native lfs code; the ufs-derived code already
has 64 vs. 32 logic, but as aspects of it are unsafe, and don't
entirely interoperate cleanly with the lfs 64/32 stuff, pass 2 will be
rehashing that.)
|
| 1.35 |
| 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.
|
| 1.34 |
| 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.

chopps | - Fix fallout for recent bread() change (removing cred arg).
|
| 1.32 |
| 18-Jun-2013 |
christos | Prefix most of the cpp macros with lfs_ and LFS_ to avoid conflicts with ffs.
This was done so that boot blocks that want to compile both FFS and LFS in
the same file work.
|
| 1.31 |
| 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.

dholland | Stick LFS_ in front of IFMT, IFIFO, IFREG, etc. so as not to conflict
with the UFS copies of these symbols. (Which themselves ought to have
UFS_ stuck on.)
|
| 1.27 |
| 06-Jun-2013 |
dholland | ufs -> ulfs for fsck_lfs.
|
| 1.26 |
| 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.

mlelstv | branches: 1.25.6; 1.25.12;
Three changes in a single commit.
- drop the notion of frags (LFS fragments) vs fsb (FFS fragments)
The code uses a complicated unity function that just makes the
code difficult to understand.
- support larger sector sizes. Fix disk address computations
to use DEV_BSIZE in the kernel as required by device drivers
and to use sector sizes in userland.
- Fix several locking bugs in lfs_bio.c and lfs_subr.c.

hannken | Make sure all cached buffers with valid, not yet written data have been
run through copy-on-write. Call fscow_run() with valid data where possible.
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.

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.

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.
