When CONFIG_PROC_FS isn't set, gcc warning this:
drivers/net/wireless/atmel/atmel.c:1402:12: warning: ‘atmel_proc_show’ defined but not used [-Wunused-function]
static int atmel_proc_show(struct seq_file *m, void *v)

fix this by adding #ifdef around it.

Variables len, ret, reason and crypt are assigned values that

Note: For the variable ret, a return code is being assigned, but
this is not returned and 0 is currently being returned, I believe

Driver is using boolean variables to maintain vairous status
information of adapter. These status variables are accessed by
multiple threads and there is a possibility of a race. To avoid
this, convert these variables to a set of bitops flags, to be
operated atomically.

surprise_removed
is_cmd_timedout

Driver must ensure that whenever it holds a pointer to the list
entry mwifiex_rx_reorder_tbl, it must protect the same with
rx_reorder_tbl_lock. At present there are many places where
driver does not ensure this. To cover all cases, spinlocks in
below funcions are moved out and made sure that the caller will
hold the spinlock:
mwifiex_11n_dispatch_pkt_until_start_win()
mwifiex_11n_scan_and_dispatch()
mwifiex_del_rx_reorder_entry()
mwifiex_11n_get_rx_reorder_tbl()

At present driver spinlock protects iteration of list
rx_reorder_tbl_ptr with rx_reorder_tbl_lock. To protect the
individual items in this list, it uses rx_pkt_lock. But, we can
use a single rx_reorder_tbl_lock for both purposes. This patch
replaces rx_pkt_lock by rx_reorder_tbl_lock.

This bug was introduced by:
commit 15a3e845b01c ("perf/x86/intel/uncore: Fix SBOX support for Broadwell CPUs")
The index of "QPI Port 2 filter" was hardcode to 2, but this conflicts with the
index of "PCU.3" which is "HSWEP_PCI_PCU_3", which equals to 2 as well.
To fix the conflict, the hardcoded index needs to be cleaned up:
- introduce a new enumerator "BDX_PCI_QPI_PORT2_FILTER" for "QPI Port 2
filter" on Broadwell,
- increase UNCORE_EXTRA_PCI_DEV_MAX by one,
- clean up the hardcoded index.

I hit the following problem when I tried to use bpftool
to dump a percpu array.
$ sudo ./bpftool map show
61: percpu_array name stub flags 0x0
key 4B value 4B max_entries 1 memlock 4096B
...
$ sudo ./bpftool map dump id 61
bpftool: malloc.c:2406: sysmalloc: Assertion
`(old_top == initial_top (av) && old_size == 0) || \
((unsigned long) (old_size) >= MINSIZE && \
prev_inuse (old_top) && \
((unsigned long) old_end & (pagesize - 1)) == 0)'
failed.
Aborted
Further debugging revealed that this is due to
miscommunication between bpftool and kernel.
For example, for the above percpu_array with value size of 4B.
The map info returned to user space has value size of 4B.
In bpftool, the values array for lookup is allocated like:
info->value_size * get_possible_cpus() = 4 * get_possible_cpus()
In kernel (kernel/bpf/syscall.c), the values array size is
rounded up to multiple of 8.
round_up(map->value_size, 8) * num_possible_cpus()
= 8 * num_possible_cpus()
So when kernel copies the values to user buffer, the kernel will
overwrite beyond user buffer boundary.
This patch fixed the issue by allocating and stepping through
percpu map value array properly in bpftool.

The variable 'context->module.name' may be null pointer when

importantly it too calls an __init function which would require it to be

This patch implements following ethtool stats fields for netvsc:
cpu<n>_tx/rx_packets/bytes
cpu<n>_vf_tx/rx_packets/bytes
Corresponding per-cpu counters already exist in current code. Exposing
these counters will help troubleshooting performance issues.
for_each_present_cpu() was used instead of for_each_possible_cpu().
for_each_possible_cpu() would create very long and useless output.
It is still being used for internal buffer, but not for ethtool
output.
There could be an overflow if cpu was added between ethtool
call netvsc_get_sset_count() and netvsc_get_ethtool_stats() and
netvsc_get_strings(). (still safe if cpu was removed)
ethtool makes these three function calls separately.
As long as we use ethtool, I can't see any clean solution.
Currently and in foreseeable short term, Hyper-V doesn't support
cpu hot-plug. Plus, ethtool is for admin use. Unlikely the admin
would perform such combo operations.
Changes in v2:
- Remove cpp style comment
- Resubmit after freeze
Changes in v3:
- Reimplemented with kvmalloc instead of alloc_percpu
Changes in v4:
- Fixed inconsistent array size
- Use kvmalloc_array instead of kvmalloc

The hs_ctr variable can just be int instead of long, so also change
kstrtol() to kstrtoint() and leave the format string as %d.
Also add 2 header files since they are used in mtm.c and we prefer
not to depend on accidental/indirect #includes.

Petr Machata says:
====================
A test for mirror-to-gretap with team in UL packet path
This patchset adds a test for "tc action mirred mirror" where the
mirrored-to device is a gretap, and underlay path contains a team
device.
In patch #1 require_command() is added, which should henceforth be used
to declare dependence on a certain tool.
In patch #2, two new functions, team_create() and team_destroy(), are
added to lib.sh.
The newly-added test uses arping, which isn't necessarily available.
Therefore patch #3 introduces $ARPING, and a preexisting test is fixed
to require_command $ARPING.
In patches #4 and #5, two new tests are added. In both cases, a team
device is on egress path of a mirrored packet in a mirror-to-gretap
scenario. In the first one, the team device is in loadbalance mode, in
the second one it's in lacp mode. (The difference in modes necessitates
a different testing strategy, hence two test cases instead of just
parameterizing one.)

This tests mirror-to-gretap when an underlay packet path includes a team
device which is not in loadbalance mode, but in LACP mode. The test
manipulates LAG membership to achieve changes in txability, thus making
sure that a driver that offloads mirror-to-gretap doesn't just consider
upness of a device.

Test for "tc action mirred egress mirror" that mirrors to gretap when
the underlay route points at a VLAN-aware bridge (802.1q), and the
traffic egresses the bridge through a team device. Test upping and
downing individual team device slaves and verify the traffic flows as
expected.

Instead of relying on "arping" being installed everywhere under that
name, introduce a variable $ARPING like the other tools do.
Convert an existing test, mirror_gre_vlan_bridge_1q.sh to
require_command $ARPING and then invoke arping through the variable.

The logic for testing whether a certain command is available is used
several times in the current code base. The tests in follow-up patches
add more requirements like that.
Therefore extract the logic into a named function, require_command(),
that can be used directly from lib.sh as well as from any test that
wishes to declare dependence on some command.
