thorpej | In pktq_flush():
- Run a dummy softint at IPL_SOFTNET on all CPUs to ensure that the
ISR for this pktqueue is not running (addresses a pre-existing XXX).
- Hold the barrier lock around the critical section to ensure that
implicit pktq_barrier() calls via pktq_ifdetach() are held off during
the critical section.
- Ensure the critical section completes in minimal time by not freeing
memory during the critical section; instead, just build a list of the
packets pulled out of the per-CPU queues and free them after the critical
section is over.

thorpej | Re-factor how pktq_barrier() is issued by if_detach().
Rather than excplicitly referencing ip_pktq and ip6_pktq in if_detach(),
instead add all pktqueues to a global list. This list is then used in
the new pktq_ifdetach() function to issue a barrier on all pktqueues.
Note that the performance of this list is not critical; it will seldom
be accessed (then pktqueues are created/destroyed and when network
interfaces are detached), and so a simple synchronization strategy using
a rwlock is sufficient.

thorpej | pktqueue: Re-factor sysctl handling.
Provide a new pktq_sysctl_setup() function that attaches standard
pktq sysctl nodes below a specified parent node, with either a
fixed node ID or CTL_CREATE to dynamically assign node IDs. Make
all of the sysctl handlers private to pktqueue.c, and remove the
INET- and INET6-specific pktqueue sysctl code from net/if.c.

thorpej | pktq_rps_hash(): Make the "funcp" argument const.

thorpej | pktq_dequeue(): Prevent packets from getting stuck beind barrier markers.
pktq_barrier() ensures that all packets enqueued before the barrier have
been dequeued before the barrier returns. However, previously, pktq_dequeue()
would return NULL when a barrier marker was encountered. If there were
packets queued up behind the marker and no additional softint were scheduled
for the pktqueue, those packets would end up stranded. pktq_dequeue() now
continues to the next slot after the marker, ensuring that processing can
continue after the barrier has been signaled.

pktqueue(9): Use percpu_create to allow early initialization.
Otherwise pktqueues can't be created before all CPUs are detected --
they will have a queue only for the primary CPU, not for others.
This will also be necessary if we want to add CPU hotplug (still need
some way to block hotplug during pktq_set_maxlen but it's a start).

thorpej | Use percpu_foreach_xcall() to gather volatile per-cpu counters. These
must be serialized against the interrupts / soft-interrupts in which
they're manipulated, as well as protected from non-atomic 64-bit memory
loads on 32-bit platforms.

msaitoh | branches: 1.10.6;
- Fix a bug that drop counter shows incorrect vaule like
"net.inet.ip.ifq.drops = 72059810241052672"
- Change pktq's length sysctl to uint64_t.

chs | branches: 1.9.8; 1.9.10;
remove checks for failure after memory allocation calls that cannot fail:
kmem_alloc() with KM_SLEEP
kmem_zalloc() with KM_SLEEP
percpu_alloc()
pserialize_create()
psref_class_create()
all of these paths include an assertion that the allocation has not failed,
so callers should not assert that again.

ozaki-r | branches: 1.8.2; 1.8.6; 1.8.8;
Fix pktq_enqueue for rump
Add _RUMP_NATIVE_ABI to the macro condition for i386 and x86_64 because
_RUMPKERNEL is not defined for them. See sys/rump/Makefile.rump.
Found by ATF

ozaki-r | Restore RPS of pktq_enqueue unless _RUMPKERNEL
It's a workaround and would be fixed in rump soon.

ozaki-r | Move sysctl_pktq_{maxlen,count} to pktqueue.c and make them global
They will be used by bridge.
ok rmind@
|
| 1.5 |
| 16-Jun-2014 |
ozaki-r | Add 3rd argument to pktq_create to pass sc
It will be used to pass bridge sc for bridge_forward softint.

rmind | pktqueue: add or fix some comments, remove some header inclusions.
|
| 1.3 |
| 09-Jun-2014 |
rmind | Restore the assert in RUMP's softint_schedule_cpu() and just ensure
curcpu() in the caller.
|
| 1.2 |
| 09-Jun-2014 |
rmind | Implement pktq_set_maxlen() and let sysctl net.inet.{ip,ip6}.ifq.maxlen be
changed on the fly again.
|
| 1.1 |
| 05-Jun-2014 |
rmind | - Implement pktqueue interface for lockless IP input queue.
- Replace ipintrq and ip6intrq with the pktqueue mechanism.
- Eliminate kernel-lock from ipintr() and ip6intr().
- Some preparation work to push softnet_lock out of ipintr().
