rt2x00: fix stop queue

Since we clear QUEUE_STARTED in rt2x00queue_stop_queue(), following
call to rt2x00queue_pause_queue() reduce to noop, i.e we do not
stop queue in mac80211.

To fix that introduce rt2x00queue_pause_queue_nocheck() function,
which will stop queue in mac80211 directly.

Note that rt2x00_start_queue() explicitly set QUEUE_PAUSED bit.

Note also that reordering operations i.e. first call to
rt2x00queue_pause_queue() and then clear QUEUE_STARTED bit, will race
with rt2x00queue_unpause_queue(), so calling ieee80211_stop_queue()

In certain circumstances, such as an HCI driver using __hci_cmd_sync_ev

chance that hci_event_packet will call hci_req_cmd_complete twice (once
for the explicitly looked after event and another time in the actual

In the case of __hci_cmd_sync_ev this introduces a race where the first
call wakes up the blocking __hci_cmd_sync_ev and lets it complete.
However, by the time that a second __hci_cmd_sync_ev call is already in
progress the second hci_req_cmd_complete call (from the previous
operation) will wake up the blocking function prematurely and cause it

ath9k_htc: do some initial hardware configuration

Currently we configure harwdare and clock, only after

11 years agomwifiex: fix IRQ enable/disable
Daniel Drake [Sat, 13 Jul 2013 14:57:10 +0000 (10:57 -0400)]
mwifiex: fix IRQ enable/disable

During tear down (e.g. mwifiex_sdio_remove during system suspend),
mwifiex left IRQs enabled for a significant period of time when it was
unable to handle them correctly. This caused interrupt storms and
interfered with the bluetooth interface on the same SDIO card.

Solve this by disabling interrupts at the point when they can no longer
be handled correctly, which is at the start of mwifiex_remove_card().

For cleanliness, we now enable interrupts in the mwifiex_add_card() path,
to be symmetrical with the disabling of interrupts. We also couple the
registration of the sdio IRQ handler with the actual enable/disable of
interrupts at the hardware level.

I also removed a write to this register in mwifiex_init_sdio which seemed
pointless and won't cause any ill effects now that we only register
the SDIO IRQ handler when we are ready to accept interrupts.

Includes some corrections from Amitkumar Karwar.

mac80211: prevent the buffering or frame transmission to non-assoc mesh STA

This patch is intended to avoid the buffering to non-assoc mesh STA
and also to avoid the triggering of frame to non-assoc mesh STA which
could cause kernel panic in specific hw.

One of the examples, is kernel panic happens to ath9k if user space
inserts the mesh STA and not proceed with the SAE and AMPE, and later
the same mesh STA is detected again. The sta_state of the mesh STA remains
at IEEE80211_STA_NONE and if the ieee80211_sta_ps_deliver_wakeup is called
and subsequently the ath_tx_aggr_wakeup, the kernel panic due to
ath_tx_node_init is not called before to initialize the require data
structures.

rtlwifi: Fix build errors for unusual cases

The present build configuration for the rtlwifi family of drivers will
fail under two known conditions:

(1) If rtlwifi is selected without selecting any of the dependent drivers,
    there are errors in the build.
(2) If the PCI drivers are built into the kernel and the USB drivers are modules,
    or vice versa, there are missing globals.

The first condition is fixed by never building rtlwifi unless at least one
of the device drivers is selected. The second failure is fixed by splitting
the PCI and USB codes out of rtlwifi, and creating their own mini drivers.
If the drivers that use them are modules, they will also be modules.

Although a number of files are touched by this patch, only Makefile and Kconfig
have undergone significant changes. The only modifications to the other files
were to export entry points needed by the new rtl_pci and rtl_usb units, or to
rename two variables that had names that were likely to cause namespace collisions.

mac80211: fix duplicate retransmission detection

erroneously attempts to do the check for every frame,
even frames that don't have a sequence control field or

This is problematic because it causes the code to access

there will drop packets erroneously.

Correct the code to not do duplicate detection for such

Now, this uses SLUB pretty much unmodified, but as it is the -rt kernel
with CONFIG_PREEMPT_RT set, spinlocks are mutexes, although they do
disable migration. But the SLUB code is relatively lockless, and the
spin_locks there are raw_spin_locks (not converted to mutexes), thus I
believe this bug can happen in mainline without -rt features. The -rt
patch is just good at triggering mainline bugs ;-)

Anyway, looking at where this crashed, it seems that the page variable
can be NULL when passed to the node_match() function (which does not
check if it is NULL). When this happens we get the above panic.

As page is only used in slab_alloc() to check if the node matches, if
it's NULL I'm assuming that we can say it doesn't and call the
__slab_alloc() code. Is this a correct assumption?
