f9e565abca sort: Make NetBSD sort tests compatible with our sort
This diff primarily adds/removes flags to make the tests compatible with
sort.  Two tests are removed.  One test is changed to expect fail due to
a bug.

71ec05a212 sort: Cache value of MB_CUR_MAX
Every usage of MB_CUR_MAX results in a call to __mb_cur_max.  This is
inefficient and redundant.  Caching the value of MB_CUR_MAX in a global
variable removes these calls and speeds up the runtime of sort.  For
numeric sorting, runtime is almost halved in some tests.

8b3c4231ab posix timers: Check for overflow when converting to ns
Disallow a time or timer period value when the conversion to nanoseconds
would overflow.  Otherwise it is possible to trigger a divison by zero
in realtime_expire_l(), where we compute the number of overruns by
dividing by the timer interval.

9246b3090c fork: Suspend other threads if both RFPROC and RFMEM are not set
Otherwise, a multithreaded parent process may trigger races in
vm_forkproc() if one thread calls rfork() with RFMEM set and another
calls rfork() without RFMEM.

Also simplify vm_forkproc() a bit, vmspace_unshare() already checks to
see if the address space is shared.

02cffbc250 tcp: Incorrect KASSERT causes a panic in rack
Skyzall found an interesting panic in rack. When a SYN and FIN are
both sent together a KASSERT gets tripped where it is validating that
a mbuf pointer is in the sendmap. But a SYN and FIN often will not
have a mbuf pointer. So the fix is two fold a) make sure that the
SYN and FIN split the right way when cloning an RSM SYN on left
edge and FIN on right. And also make sure the KASSERT properly
accounts for the case that we have a SYN or FIN so we don't
panic.

d8acd2681b Fix mbuf leaks in various pru_send implementations
The various protocol implementations are not very consistent about
freeing mbufs in error paths.  In general, all protocols must free both
"m" and "control" upon an error, except if PRUS_NOTREADY is specified
(this is only implemented by TCP and unix(4) and requires further work
not handled in this diff), in which case "control" still must be freed.

This diff plugs various leaks in the pru_send implementations.

Merge commit '2858419a0ee2b8f5827de72c00618bcd69ebc5fc'

This update fixes the initialization of "scale" to 20 if started with
-l and the initial statement leads to an error (e.g. contains a syntax
error). Scale was initialized to 0 in that case.

Another change is the support of job control in interactive mode with
line editing enabled. The control characters have been interpreted as
editing commands only, prior to this version.

a3628327e7 Ensure that files with no allocated blocks are trimmed to zero length.
UFS does not allow files to end with a hole; it requires that the
last block of a file be allocated. As fsck_ffs(8) initially scans
each allocated inode, it tracks the last allocated block in the
inode. It then checks that the inode's size falls in the last
allocated block. If the last allocated block falls before the size,
a `file size beyond end of allocated file' warning is issued and
the file is shortened to reference the last allocated block (to avoid
having it reference a hole at its end). If the last allocated block
falls after the size, a `partially truncated file' warning is issued
and all blocks following the block referenced by the size are freed.

Because of an incorrect unsigned comparison, this test was failing
to handle files with no allocated blocks but non-zero size (which
should have had their size reset to zero). Once that was fixed the
test started incorrectly complaining about short symbolic links
that place the link path in the inode rather than in a disk block.
Because these symbolic links have a non-zero size, but no allocated
blocks, fsck_ffs wanted to zero out their size. This patch has to
detect and avoid changing the size of such symbolic links.
