should fix a crash seen by by Chavdar Ivanov reported on current-users.
move the rx and tx list clean up into their own functions, and call the
rx clean up function from the init function if something fails. this
should fix a potential leak in this case, and generally frees up memory
that won't be used without a successful init phase again.
slight application of 'static', much more could be done.
that until all current uses of IFS are complete (as we have IFS's
value cached in ifs - if IFS alters, ifs might point anywhere).
Handle this by deferring assignments to IFS until everything is done.
This makes us appear to comply with the (currently) proposed requirement
for read by POSIX that field splitting complete before vars are
assigned. (Other shells, like dash, ksh93, yash, bosh behave like this)
That might end up being unspecified though, as other shells (bosh,
mksh) assign each field to its var as it is delimited (though bosh
appears to have bugs). If we wanted to go that route, the issue here
could have been handled by re-doing the init of ifs after every
setvar() that is performed here (except the last, after which it is
no longer needed).
XXX pullup -10
syscall/trap entry, eliminating a test+branch on every syscall/trap.
This wasn't possible in the 3.99.x timeframe when l->l_cred came about
because there wasn't a reliable/timely way to force an ONPROC LWP running on
a remote CPU into the kernel (which is just about the only new thing in
this scheme).
l_biglocks is a now-defunct temporary storage used only when
sleeping; l_blcnt is the number of kernel locks held by the lwp when
not sleeping.
Should fix arm builds.
- Allows overriding default from /etc/npf.conf
- Indicate rules file used in output
- Drop check for file presence in script - rely on npf exiting with error
functional change but it does get rid of a bunch of assumptions about how
mi_userret() works making it easier to adjust in that in the future, and
works as a kind of documentation too.

Originally written by kevlo@o for OpenBSD, and ported by knakahara@,
msaitoh@, and myself.
The driver is *EXPERIMENTAL* at the moment, as some minor error
handling paths are not fully implemented.
Hardware VLAN tagging and TSO are not supported yet.
Although, we have never observed strange behaviors at least on amd64,
aarch64{,eb}, and evbppc (IBM405), except for PR port-arm/57643.
We will send pullup request to netbsd-10, after successful snapshot
build for -current.
local copy of the atomic access support functions for machines that do not
implement all required ops in hardware (like 32bit sparc).
XXX would be better to figure out a way to share this copy with libc
(thereby using half as many RAS sections). But even if we would share it,
we have to init it early enough for ld.elf_so internal uses.
