socket names:
- In unp_setsockaddr() and unp_setpeeraddr(), if the socket name can't
fit into a single mbuf, allocate enough external storage space to
hold it.
- In unp_bind() and unp_connect(), perform a similar operation, but allocate
one extra byte, and ensure that the pathname is nul-terminated.
Many thanks to enami tsugutomo <enami@cv.sony.co.jp> for the sanity
checking.
- Add a comment describing my feelings about this interface, in general.
- Remove the COMPAT_OLDSOCK length hack. Instead, if the socket argument
is too long to fit in an mbuf, allocate enough external storage to
hold it.
- If the socket argument is a sockaddr, don't allow the length to be
greater than 255, as that would overflow sa_len.

the format modifer. Reported by and suggested fix from Daniel G. Pouzzner
in PR #2633. Final fix is slightly different now that we support the %q
modifier. This fix also includes the equivalent fix for sprintf().
- Disallow < 1 values for SO_SNDBUF, SO_RCVBUF, SO_SNDLOWAT, and
SO_RCVLOWAT; return EINVAL if the user attempts to set <= 0.
Inspired by PR #3770, from Havard Eidnes <he@vader.runit.sintef.no>.
- For SO_SNDLOWAT and SO_RCVLOWAT, don't let the low-water mark get
set above the high-water mark. Behavior is now consistent with
BSD/OS: If such an attempt is made, silently truncate to the high-water
value.
- If RB_ASKNAME, prompt for the dump device, defaulting to
partition 'b' of the root device, if the root device is a disk.
- Else, if dumpspec is set to "none", do not configure a dump device.
- Else, if dumpspec is set by config(8), attempt to use that device.
- Else, dumpspec is wildcarded or unspecified; if the root device is
a disk, select partition b. (which was the previous default dump
partition)
Note, dumps to a local disk now work even if root is on nfs.
so that if the drop to spl0() causes another panic (e.g. because there's
still some fatal hardware interrupt that's pending) we'll know that we
dropped IPL to sync the disks.
__VM_PMAP_HACK is defined (for temporary compatibility).
The __VM_PMAP_HACK code should be removed after all the
ports that define it have removed all vm_pmap references.
fill the socket's creation time into the stat structure's st_[acm]time fields:
POSIX requires this behavior for pipe(2). N.B.: updating the st_[am]time fields
when reading/writing the pipe is neither required nor implemented, though.
(1): "substart == ex->ex_end" and "subend == ex->ex_start"
are completely legal parameters for extent_alloc_subregion()
(2): "(subend - substart) + 1" can cause an overflow if the whole
numeric range is covered by the extent.
Submitted by Matthias Drochner <drochner@zelz26.zel.kfa-juelich.de>
in PR #3119.
1) Eliminate all of the null component name special cases; handle runs of
slashes and leading and trailing slashes completely differently.
2) Return ENOENT when doing a lookup through an empty symlink.
3) Enforce that we're doing a lookup through a directory in in chdir() and
lookup() rather than in foo_lookup().
