bhyve: allow overriding snapshot socket directory

2026-07-08T16:10:14+00:00

By default bhyve(8) creates a snapshot socket in
"/var/run/bhyve/" (BHYVE_RUN_DIR).
As this is a system directory not writable by users,
this does not work when bhyve(8) is being started
as a non-root user.

Address that by allowing to override this directory.
In bhyve(8) it is done by setting 'rundir' option
with '-o rundir='.

In bhyvectl(8) it is done with '--rundir='.

Regen syscalls tables.

2026-07-08T15:26:57+00:00

This catches up with 692b0ef1506ba which added CAPENABLED to
clock_nanosleep(). Curiously recent additions of the pdopenpid(2) and
pddupfd(2) were done before the cited commit, and that regen did not
included the change.

lagg: re-check port caps after bringing up a port

2026-07-08T12:27:58+00:00

Some nic drivers (including iflib) do not initialize if_hwassist
until after the interface is brought up.  If a lagg member is included
in a lagg when its not yet been brought up, that will cause lagg to see
if_hwassist=0 and will disable all checksum offload, etc, on the interface.
This is almost impossible to debug without kgdb or dtrace, as ifconfig does
not surface if_hwassist.

Fix this by re-calculating lagg caps (including if_hwassist) after adding a port.

I encountered this problem when I had a commented-out if_foo1=up entry in
my rc.conf that i neglected to uncomment when I was re-configuring a lagg.
