Retire bio_driver[12] (aliases for b_io.bio_driver[12]) these fields are
reserved for device driver use and can as such never have any interest
in the buf end of things.
rate is how fast modems exchange symbols. Bit rate is how many bits
per second the serial port nominally communicates at. Try to use bit
rate consistently where that's what is ment. The default data rate is
now 9600 baud. 300 baud being default pre-dates 4.4-LITE1. Document
that tip doesn't respect the system default rate for a given channel.
Sorry guys, but no ucbvax, kremvax or kgbvax added to the example.

closer to reality. More work remains to be done. st_mtime should
be the most complete based on IEEE Std 1003.1, 2003 Edition, a
review of ufs_vnops.c, and some experimentation.
- Return NULL instead of returning memory outside of the stackgap
in stackgap_alloc() (FreeBSD-SA-00:42.linux)
- Check for stackgap_alloc() returning NULL in svr4_emul_find(),
and clean_pipe().
- Avoid integer overflow on large nfds argument in svr4_sys_poll()
- Reject negative nbytes argument in svr4_sys_getdents()
- Don't copy out past the end of the struct componentname
pathname buffer in svr4_sys_resolvepath()
- Reject out-of-range signal numbers in svr4_sys_sigaction(),
svr4_sys_signal(), and svr4_sys_kill().
- Don't malloc() user-specified lengths in show_ioc() and
show_strbuf(), place arbitrary limits instead.
- Range-check lengths in si_listen(), ti_getinfo(), ti_bind(),
svr4_do_putmsg(), svr4_do_getmsg(), svr4_stream_ti_ioctl().
Some fixes obtain from OpenBSD.
what the entry does for people that are not used to reading
/etc/remote files every day. Keep arpavax, because it is a cool name,
but remove the phone number listed. arpavax hasn't been answering
that number for a while :-)
pick up the DEVFS inode number from the dev_t and find our directory
entry from that, we don't need to scan the directory to find it.
This also solves an issue with on-demand devices in subdirectories.

by libguile that needs to know the base of the RSE backing store. We
currently do not export the fixed address to userland by means of a
sysctl so user code needs to hardcode it for now. This will be revisited
later.
The RSE backing store is now at the bottom of region 4. The memory stack
is at the top of region 4. This means that the whole region is usable
for the stacks, giving a 61-bit stack space.

the old (now invalid) mbuf to be passed to BPF_MTAP.

is non-free. (More checks can/should be added in the future.)
Use M_ASSERTVALID in BPF_MTAP so that we catch when freed mbufs are
passed in, even if no bpf listeners are active.
Inspired by a bug in if_dc caught by Kenjiro Cho.
rijndael_blockDecrypt() as both input and output.
This property is important because inside rijndael we can get away
with allocating just a 16 byte "work" buffer on the stack (which
is very cheap), whereas the calling code would need to allocate the
full sized buffer, and in all likelyhood would have to do so with
an expensive malloc(9).
original intention of the less restrictive permissions was to allow
users to move or delete recovered files that they own. However, it
is better to not create world-writable directories by default; the
administrator can always pre-create lost+found if different permissions
are desired.

table, acquiring the necessary locks as it works. It usually returns
two references to the new descriptor: one in the descriptor table
and one via a pointer argument.
As falloc releases the FILEDESC lock before returning, there is a
potential for a process to close the reference in the file descriptor
table before falloc's caller gets to use the file. I don't think this
can happen in practice at the moment, because Giant indirectly protects
closes.
To stop the file being completly closed in this situation, this change
makes falloc set the refcount to two when both references are returned.
This makes life easier for several of falloc's callers, because the
first thing they previously did was grab an extra reference on the
file.
