a26e895f3d tests: Only log critical errors from scapy
Since 2.4.5 scapy started issuing warnings about a few different
configurations during our tests. These are harmless, but they generate
stderr output, which upsets atf_check.

Configure scapy to only log critical errors (and thus not warnings) to
fix these tests.

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.

Commit 81728a538 ("Split rtinit() into multiple functions.") removed
the initialization of sa6, but not one of its uses.  This meant that we
were passing an uninitialized sockaddr as the address to
lltable_prefix_free().  Remove the variable outright to fix the problem.

8c39e25220 contrib/bc: update to version 4.0.2
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.

4772e86beb xen/blkback: fix reconnection of backend
The hotplug script will be executed only once for each backend,
regardless of the frontend triggering reconnections. Fix blkback to
deal with the hotplug script being executed only once, so that
reconnections don't stall waiting for a hotplug script execution
that will never happen.

As a result of the fix move the initialization of dev_mode, dev_type
and dev_name to the watch callback, as they should be set only once
the first time the backend connects.

This fix is specially relevant for guests wanting to use UEFI OVMF
firmware, because OVMF will use Xen PV block devices and disconnect
afterwards, thus allowing them to be used by the guest OS. Without
this change the guest OS will stall waiting for the block backed to
attach.

4b86a24a76 tcp: In rack, we must only convert restored rtt when the hostcache does restore them.
Rack now after the previous commit is very careful to translate any
value in the hostcache for srtt/rttvar into its proper format. However
there is a snafu here in that if tp->srtt is 0 is the only time that
the HC will actually restore the srtt. We need to then only convert
the srtt restored when it is actually restored. We do this by making
sure it was zero before the call to cc_conn_init and it is non-zero
afterwards.

the preservation of the string itself is not enough, the 'seen'

clear string (it cannot), call to _rtld_error() from errmsg_restore()
