3e4993b396 fix unused variable warnings. 2013-10-19 01:09:58 +00:00

855bb66ef7 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.

c13a12500a 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.

5fce92dbf7 Move the dinode (on-disk inode) structures to lfs.h, since they are
and will be obviously required by userland tools that need to read
the on-disk structures.

Also, DINODE{1,2}_SIZE -> LFS_DINODE{1,2}_SIZE.

a4fc39c06d 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.

1ebd9aa225 ufs -> ulfs for fsck_lfs. 2013-06-06 00:52:50 +00:00

dcd34a91c5 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.

7974872552 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.

5d2bff060a 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.

29f1062b46 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.)

2d66b2737e Move the definition of simple_lock() and simple_unlock() to a common
header, since more of the LFS macros now use these functions.  Since
we're outside of the kernel, these are defined to be empty.

5d2f3e4908 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.

42614ed3f3 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.
