bouyer 22d556f6cf Make sure a buffer optained from bread() is always bresle()'d in case of 
error. Closes PR kern/1448 from Wolfgang Solfrank.

bouyer 3efc699962 Sanity check a few values in the superblock, to avoid mallocing huge 
memory area if we try to mount a corrupted filesystem. Fixes kern/3933.

thorpej f7948d05a1 Use DINODE_SIZE rather than pointer arithmetic. 1998-10-23 00:31:28 +00:00
thorpej 60cfe320cc Use the pool allocator and the "nointr" pool page allocator for FFS inodes. 
XXX MFS also comes in here for inodes, and used a different malloc type,
but the structure is the same, so we just use the FFS inode pool.

kleink 382743ada3 Convert fsync vnode operator implementations and usage from the old `waitfor' 
argument and MNT_WAIT/MNT_NOWAIT to `flags' and FSYNC_WAIT.

bouyer 091dafd39f Add support for reading/writing FFS in non-native byte order, conditioned 
to "options FFS_EI". 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).
This required the addition of a "um_flags" field to struct ufsmount.
ffs_bswap.c contains superblock and inode byteswap routines also used
by userland utilities.

mjacob 949982f2a4 In calculating the f_bavail field, don't take 32 bit quantities and 
multiply them by 90 (to be divided by 100) and expect them to be sane
for very large values (I was getting a negative 'avail' count).

fvdl acffafa288 Oops, I messed up the lock. Reverting it until I have time to fix it, 
to avoid people getting trouble after the supscan hits.

fvdl b362aa16be Put lock around inode hashing, because getnewvnode or MALLOC might block, 
creating race conditions.

bouyer 76c414a957 Add support for ext2fs, this needed a few modifications to ufs/ufs/inode.h: 
- added an "union inode_ext" to struct inode, for the per-fs extentions.
  For now only ext2fs uses it.
- i_din is now an union:
	union {
		struct  dinode ffs_din; /* 128 bytes of the on-disk dinode. */
		struct ext2fs_dinode e2fs_din; /* 128 bytes of the on-disk dinode. */
	} i_din
  Added a lot of #define i_ffs_* and i_e2fs_* to access the fields.
- Added two macros: FFS_ITIMES and EXT2FS_ITIMES. ITIMES calls the rigth
  macro, depending on the time of the inode. ITIMES is used where necessary,
  FFS_ITIMES and EXT2FS_ITIMES in other places.

mycroft 66c4e32b11 Just increment the generation count. Using the time is bogus and defeats 
fsirand(8).

thorpej 727078d31e - Add ffs_mountroot to ffs_vfsops.

cgd 90688fce27 Change the second and third args to struct vfsops' (*vfs_mount)() to 
'const char *', and 'void *', respectively.  The second arg is taken directly
from user arguments, and is const there, so must be const in the prototypes
and functions.  The third arg is also taken directly from user arguments.
It doesn't have to be changed, but since it's cleaner to keep the type
the same as the user arg's type, and I'm already making the 'const char *'
change...
