If change_interface gets invoked during a firmware
restart, it may crash; prevent that from happening
by checking if ctx->vif is assigned.

Additionally, in my initial commit I forgot to set
the vif->p2p variable correctly, so fix that too.

Some clients seem to rely upon the reception of BlockAckReqs to flush
their rx reorder buffer. In order to fix aggregation for these clients
carl9170 should set IEEE80211_TX_STAT_AMPDU_NO_BACK to generate a
BlockAckReq if the transmission of an AMPDU subframe fails.

This fixes aggregation problems with Intel 5100 Windows STAs (and maybe
others as well).

After new NetworkManager 0.8.996 changes, hardware scanning is causing
microcode errors as reported here:
https://bugzilla.redhat.com/show_bug.cgi?id=683571
and sometimes kernel crashes:
https://bugzilla.redhat.com/show_bug.cgi?id=688252

Also with hw scan there are very bad performance on some systems
as reported here:
https://bugzilla.redhat.com/show_bug.cgi?id=671366

Since Intel no longer supports 3945, there is no chance to get proper
firmware fixes, we need workaround problems by disable hardware scanning
by default.

Suppose the aggregation reorder buffer looks like this:

x-T-R1-y-R2,

where x and y are frames that have not been received, T is a received
frame that has timed out, and R1,R2 are received frames that have not
yet timed out. The proper behavior in this scenario is to move the
window past x (skipping it), release T and R1, and leave the window at y
until y is received or R2 times out.

As written, this code will instead leave the window at R1, because it
has not yet timed out. Fix this by exiting the reorder loop only when
the frame that has not timed out AND there are skipped frames earlier in
the current valid window.

This patch adds to the fix "fix BSS double-unlinking"
(commit 3207390a) by Johannes Berg.

It turns out, that the double-unlinking scenario can also occur if expired
BSS elements are removed whilst an interface is performing association.

To work around that, replace list_del with list_del_init also in the
"cfg80211_bss_expire" function, so that the check for whether the BSS still is
in the list works correctly in cfg80211_unlink_bss.

The ieee80211_key struct can be kfree()d several times in the function, for
example if some of the key setup functions fails beforehand, but there's no
check if the struct is still valid before we call memcpy() and INIT_LIST_HEAD()

commit 86271e46 introduced a
regression that caused mac80211 queues in stopped state.

ath_drain_all_txq is called in driver flush which would reset
the stopped flag and the mac80211 queues were never started
after that. iperf traffic is completely stalled due to this issue.

Restart the mac80211 queues in driver flush only if the txqs were
drained.

With the recent tx status optimization in mac80211, we bail out as
and and when invalid rate index is found. So the behavior of resetting
rate idx to -1 and count to 0 has changed for the rate indexes that
were not part of the driver's retry series.

This has resulted in ath9k using incorrect rate table index which
caused the system to panic. Ideally ath9k need to loop only for the
indexes that were part of the retry series and so simply use hw->max_rates
as the loop counter.

Pasted the stack trace of the panic issue for reference.

Unless aggregation is enabled we don't initialize the TID structure.
Thus accesing the elements of the TID structure when aggregation is

'buffer' string is copied from userspace.  It is not checked whether it is
zero terminated.  This may lead to overflow inside of simple_strtoul().
Changli Gao suggested to copy not more than user supplied 'size' bytes.

It was introduced before the git epoch.  Files "ipt_CLUSTERIP/*" are
root writable only by default, however, on some setups permissions might be
relaxed to e.g. network admin user.

commit f3c5c1bf (make ip_tables reentrant) introduced a race in
handling the stackptr restore, at the end of ipt_do_table()

We should do it before the call to xt_info_rdunlock_bh(), or we allow
cpu preemption and another cpu overwrites stackptr of original one.

A second fix is to change the underflow test to check the origptr value
instead of 0 to detect underflow, or else we allow a jump from different
hooks.

The revision of the set type was not checked at the create command: if the
userspace sent a valid set type but with not supported revision number,
it'd create a loop.
