fvdl 0b1963121a Add Kirk McKusick's soft updates code to the trunk. Not enabled by
default, as the copyright on the main file (ffs_softdep.c) is such
that is has been put into gnusrc. options SOFTDEP will pull this
in. This code also contains the trickle syncer.

Bump version number to 1.4O

enami fee96e1746 Check if the type of device node isn't VBAD before touching v_specinfo. If
the device vnode is revoked, the field is NULL and touching it causes null
pointer derefercence.

wrstuden e682a080e9 In spec_close(), if we're not doing a non-blocking close and VXLOCK is
not set, unlock the vnode before calling the device's close routine and
relock it after it returns. tty close routines will sleep waiting for
buffers to drain, which won't happen often times as the other side needs
to grab the vnode lock first.

Make all unmount routines lock the device vnode before calling VOP_CLOSE().

wrstuden 976aedb7ac Adjust mountroot routines to vrele rootvp in case of mount error. Closes

wrstuden 379a26972f Modify file systems to deal with struct lock in struct vnode. All leaf
fs's other than nfs use genfs_lock() for locking.

Modify lookup routines to set PDIRUNLOCK when they unlock the parrent.

bouyer 466d1747ff memset ump->um_e2fs to 0 after malloc, it is bigger than SBSIZE and thus some
parts were left uninitialised. The symptom was that a read-only mount tried
to rewrite back the superblock.

wrstuden 862a56e88b Modify vfsops to seperate vfs_fhtovp() into two routines. vfs_fhtovp() now
only handles the file handle to vnode conversion, and a new call,
vfs_checkexp(), performs the export verification.

thorpej 978c3d97f5 For consistency w/ FFS/LFS, define EXT2_DINODE_SIZE, and use it instead
of pointer arithmetic and/or sizeof(struct ext2fs_dinode).

bouyer b10470bc11 #include opt_uvm.h only if _KENREL and !_LKM
Make ext2fs_init() call ufs_init(). it was doing the init by itself,
testing for extern done != 0. This bug was hidden by the fact that
ext2fs_init() is called before ffs_init().

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.

bouyer 6d339338e6 Close kern/5077: When DIAGNOSTIC is defined, don't complain about
bad magic numbers at a mount attempt. A message is still printed when the
magic number is OK, but the version number or the block size is bad.
Patch from Soren S. Jorvang, but different from the one in the PR.

bouyer 459fd0e350 When allocating an inode with dtime set, also bzero e2di_blocks[]. 1997-10-27 14:43:41 +00:00
bouyer 89f2b833f4 Uses ext2fs_vinit not ufs_vinit.
In ext2fs, an inode is deleted either when mode == 0 or dtime != 0. If
  dtime != 0, reset others fields before using the inode, or we could end
  up with the wrong v_op in ext2fs_vinit.
While I'm there, kill a unused variable in ext2fs_readwrite

bouyer 6ab3092b11 Add byte-swapping functions (bswap16, bswap32, bswap64) to libkern.
Only assembly version for i386 bswap16 and bswap32 for now (bswap64 uses
bswap32). Contribution of assembly versions of these are welcome.
Add byte-swapping of ext2fs metadata for big-endian systems.
Tested on i386 and sparc.
