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 3bf14d81e9 Add support for fcntl(2) to generate VOP_FCNTL calls. Any fcntl
call with F_FSCTL set and F_SETFL calls generate calls to a new
fileop fo_fcntl. Add genfs_fcntl() and soo_fcntl() which return 0
for F_SETFL and EOPNOTSUPP otherwise. Have all leaf filesystems
use genfs_fcntl().

bouyer 466d1747ff memset ump->um_e2fs to 0 after malloc, it is bigger than SBSIZE and thus some

bouyer dc306354b0 Move the bswap functions from libutil to libc (this bups the
minor of libc and the major of libutil). For little-endian architectures
merge the bnswap() assembly versions with nto* and hton* using symbols
aliasing. Use symbol renaming for the bswap function in this case to avoid
namespace pollution.
Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian
machines, common code for inline macros go in machine/byte_swap.h
Sync libkern with libc.

kleink 933111f98f Implement support for IEEE Std 1003.1b-1993 synchronous I/O:
* in the read vnode operator, check for IO_SYNC being set in the ioflag and
  synchronously update the file's meta-data if appropriate.
* in the write vnode operator, update the appropriate checks for IO_SYNC being
  set in the ioflag to reflect that IO_DSYNC is now inclusive-or'ed into
  IO_SYNC, and require all IO_SYNC bits to be set for operations defined by
  synchronized I/O file integrity completion but not by synchronized I/O data
  integrity completion.

cgd 651b44e211 Rework the way kernel include files are installed. In the new method,
as with user-land programs, include files are installed by each directory
in the tree that has includes to install.  (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.)  The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change.  Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.

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.

UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code.  i provided some help
getting swap and paging working, and other bug fixes/ideas.  chuck
silvers <chuq@chuq.com> also provided some other fixes.

this is the rest of the MI portion changes.

this will be KNF'd shortly.  :-)

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.
