net/mlx5: prepare to add E-switch rule flags check

The tc flower filter rules are used to control E-switch from
the application side. In order to gain garanteed rule hardware
offload the skip_sw flag should be specified while applying the
rule. But some tc rules is rejected by kernel if skip_sw flag
is set by design. Currently this regards VXLAN tunneling rules,
which are applied to special VXLAN virtual devices. Albeit these
rules are applied with skip_sw flag reset kernel tries to
perform hardware offload. If kernel succeeded the in_hw flag
is set in rule properties and application should check this
flag to get know whether the applied rule is actually hardware
offloaded.

This patch prepares for the rule flags query and check in_hw flag.
The driver checks only the rules with skip_sw flag reset, so we
need to test the actual flags of rule is being applied. The pointer
to flags field into translated rule is introduced and flags are
tested directly in the rule body. It is more reliable than save and
check flags copy.

Also patch swaps the flow_tcf_apply() and flow_tcf_remove(),
we are going to call flow_tcf_remove() from flow_tcf_appy() if
no in_hw flag set found in applied rule.

This function is used by flow_fdir_filter_add() to check if same rule
exists, and by flow_fdir_filter_delete() to find flow rule to delete.

The function compared actions conf pointers, changed to compare

6 years agopci: fix parsing of address without function number

pci: fix parsing of address without function number

If the last part of the PCI address (function number) is missing,
the parsing was successful, assuming function 0.
The call to strtoul is not returning an error in such a case,
so an explicit check is inserted before.

This bug has always been there in older parsing macros:
- GET_PCIADDR_FIELD
- GET_BLACKLIST_FIELD

6 years agohash: separate lock-free and r/w lock lookup

hash: separate lock-free and r/w lock lookup

The lock-free algorithm has caused significant lookup
performance regression for certain use cases. The
regression is attributed to the use of non-relaxed
memory orderings. 2 versions of the lookup functions
are created. One that uses the RW lock and the one that
is lock-free. This restores the performance regression
caused for use cases that used RW lock version of the

6 years agoring/c11: relax ordering for load and store of the head

ring/c11: relax ordering for load and store of the head

When calling __atomic_compare_exchange_n, use relaxed ordering for the
success case, as multiple producers/consumers do not release updates to
each other so no need for acquire or release ordering.

Because the thread fence in place, ordering for the first iteration can
be relaxed.

6 years agoring/c11: keep deterministic order allowing retry to work
Gavin Hu [Fri, 9 Nov 2018 11:42:46 +0000 (19:42 +0800)]
ring/c11: keep deterministic order allowing retry to work

Use case scenario:
1) Thread 1 is enqueuing. It reads prod.head and gets stalled for some
   reasons (running out of cpu time, preempted,...)
2) Thread 2 is enqueuing. It succeeds in enqueuing and moves prod.head
   forward.
3) Thread 3 is dequeuing. It succeeds in dequeuing and moves the cons.tail
   beyond the prod.head read by thread 1.
4) Thread 1 is re-scheduled. It reads cons.tail.

cpu1(producer)      cpu2(producer)          cpu3(consumer)
load r->prod.head
    ^               load r->prod.head
    |               load r->cons.tail
    |               store r->prod.head(+n)
  stalled           <-- enqueue ----->
    |               store r->prod.tail(+n)
    |                                        load r->cons.head
    |                                        load r->prod.tail
    |                                        store r->cons.head(+n)
    |                                        <...dequeue.....>
    v                                        store r->cons.tail(+n)
load r->cons.tail

For thread 1, the __atomic_compare_exchange_n detects the outdated
prod.head and retry the flow with the new one. This retry flow works ok on
strong ordering platform(eg:x86). But for weak ordering platforms(arm,
ppc), loading cons.tail and prod.head might be re-ordered, prod.head is new
but cons.tail becomes too old, the retry flow, based on the detection of
outdated head, does not trigger as expected, thus the outdate cons.tail
causes wrong free_entries.

Similarly, for dequeuing, outdated prod.tail leads to wrong avail_entries.

The fix is to keep the deterministic order of two loads allowing the retry
to work.

Run the ring perf test on the following testbed:
HW: ThunderX2 B0 CPU CN9975 v2.0, 2 sockets, 28core, 4 threads/core, 2.5GHz

The results showed the thread fence degrade the performance slightly, but
it is required for correctness.
