epoch_test: Assign different priorities using offset 1

2025-06-18T02:09:36+00:00

Replace the hardcoded 4 (old RQ_PPQ) by 1 (new RQ_PPQ), as all priority
levels are now treated differently.

machine/stdarg.h -> sys/stdarg.h

2025-06-11T16:39:02+00:00

Switch to using sys/stdarg.h for va_list type and va_* builtins.

Make an attempt to insert the include in a sensible place.  Where
style(9) was followed this is easy, where it was ignored, aim for the
first block of sys/*.h headers and don't get too fussy or try to fix
other style bugs.

netlink: refactor KPI for generic Netlink modules

2025-02-05T18:09:06+00:00

Now that the family and group are completely private to netlink_generic.c,
provide a simple and robust KPI, that would require very simple guarantees
from both KPI and the module:

* Strings are used only for family and group registration, that return ID:
  uint16_t genl_register_family(const char *name, ...
  uint32_t genl_register_group(uint16_t family, const char *name, ...
* Once created families and groups are guaranteed to not disappear and
  be addressable by their ID.
* All subsequent calls, including deregistration shall use ID.

callout: retire callout_async_drain()

2024-01-24T17:33:27+00:00

This function was used only in TCP before 446ccdd08e2a.  It was born in
pain in 2016 to plug different complex panics in TCP timers.  It wasn't
warmly accepted in phabricator by all of the reviewers and my recollection
of overall agreement was that "if you need this KPI, then you'd better fix
your code to not need it".  However, the function served its duty well all
the way to FreeBSD 14.  But now that TCP doesn't need it anymore, let's
retire it to reduce complexity of callout code and also to avoid its
further use.

netlink: move NETLINK define to opt_global.h

2023-10-13T07:23:47+00:00

Move the NETLINK define into opt_global.h so we can rely on it being
set correctly, without having to remember to include opt_netlink.h.
This ensures that the NETLINK define is correctly set. If not we
may end up with unloadable modules, due to missing symbols (such as
nlmsg_get_group_writer).
