corruption. Thanks to riastradh@

dholland 75571afd93 Stick ffs_ in front of the following macros:
fragstoblks()
   blkstofrags()
   fragnum()
   blknum()

to finish the job of distinguishing them from the lfs versions, which
Christos renamed the other day.

I believe this is the last of the overtly ambiguous exported symbols
from ffs... or at least, the last of the ones that conflicted with lfs.
ffs still pollutes the C namespace very broadly (as does ufs) and this
needs quite a bit more cleanup.

XXX: boo on macros with lowercase names. But I'm not tackling that just yet.
2013-06-23 22:03:34 +00:00
dholland e1610ba4cb 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

dholland 2737439da3 fsbtodb() -> FFS_FSBTODB(), EXT2_FSBTODB(), or MFS_FSBTODB()
dbtofsb() -> FFS_DBTOFSB() or EXT2_DBTOFSB()

(Christos already did the lfs ones a few days back)
2013-06-23 02:06:04 +00:00
dholland f1333577b5 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.
2013-06-19 17:51:25 +00:00
dholland 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.

riz d765f2d25b Add support for byteswapped file systems (big-endian on little-endian
host, and vice versa), to fix PR#44203.

Add support for growing (but not yet shrinking) UFS2 file systems.  Partially
addresses PR#44205.

While I'm here, reformat the code for closer adherence to KNF.

Fairly extensive testing was performed, using the shortly-to-be-committed
updated ATF tests.  Patch posted to tech-userlevel on 21 December 2010,
no comments.

riz a3a3268f75 Be explicit about byteswapped and ffsv2 file systems being currently
unsupported, while catching up to some changes in my local tree which
will hopefully support them at some time in the future.

Also, change "device" variable to "special", to reflect the fact
that resize_ffs will work on a plain file.

riz d365bee0c8 Remove bogus check which is not actually testing anything useful,
and depending on file system data, can actually be a false error.

Fixes what I was actually testing for in bin/44209, though the
actual problem was not what I originally described.

mhitch a7e78491e5 Add support for old ffsv1 superblocks. After reading an old superblock,
copy appropriate data to where they are expected in the updated superblock.
When writing the updated superblock, move the updated values back to the
old ffsv1 superblock locations.  Also check for old superblock format when
updating the last cylinder group and adjust cg_old_ncyl appropriately.
Derived from how mksf sets them.  Should address PR bin/44209.

riz 8966eced0b If we're operating on a plain file instead of a device, ftruncate() it
to ensure it's been properly extended.  Clears up some problems at certain
blocksizes which showed up during creation of atf tests, which is done
using file-backed file systems.
2010-12-08 00:25:54 +00:00
riz 0b1ff958b5 As currently written, writeat() expects disk blocks, not fs blocks, so
when testing that the last sector of the new size is writeable, make
sure we're ACTUALLY writing in the new space, instead of possibly
overwriting something in the existing fs.

Discovered while writing tests - tests which uncovered file corruption at
certain block sizes.

XXX should rewrite writeat() to expect fs blocks instead of disk blocks.
