When I added scanning to cfg80211, we got a lock dependency like this: rtnl --> cfg80211_mtx nl80211, on the other hand, has the reverse lock dependency: cfg80211_mtx --> rtnl which clearly is a bad idea. This patch reworks nl80211 to take these two locks in the other order to fix the possible, and easily triggerable, deadlock.

When the driver has been notified with a STA_REMOVE, it tears down the internal ADDBA state. On resume, trying to initiate aggregation would fail because mac80211 has not cleared the operational state for that <TID,STA>. This can be fixed by tearing down the existing sessions on a suspend. Also, the driver can initiate a new BA session when suspend is in progress. This is fixed by marking the station as being in suspend state and denying ADDBA requests for such STAs.

The MIB interrupt fires whenever counters overflow; however without support for automatic noise immunity, we can sometimes get an interrupt storm. The get_stats() callback reads the counters anyway so we can disable the interrupt for now until ANI is implemented. This fixes the issue reported in http://bugzilla.kernel.org/show_bug.cgi?id=12647.

To avoid concurrent manipulations of the sta list (which shouldn't be possible at this point, but anyway) we need to hold the sta_lock around iterating the list. At the same time, we do not need to iterate the list at all if the driver doesn't want to be notified.

AP mode currently sets up the dual stream capability for all stations. This patch fixes it by checking if the associated station supports dual stream MCS rates (8-15). We would disregard any MCS rates above 15, since Atheros HW supports only 0..15 rates currently, and can't receive at rates > 15 anyway.

Remove the PCI retry timeout code as that was just taken from ipw2100 due to historical reasons but in reality its a no-op, additionally its simply incorrect as each PCI devices has its own custom PCI configuration space on PCI config space >= 0x40. Not to mention we were trying to write 0 to a place that already has 0 on it.

If a scan is queued in STA mode while the interface is in state direct probe, authenticate or associate the scan is delayed until the interface enters disabled or associated state. But in case of direct probe-, authentication- or association- timeout sta_work will not be scheduled anymore (without external trigger) and thus the pending scan is not executed and prevents a new scan from being triggered (-EBUSY). Fix this by queueing the sta work again after direct probe-, authentication- and association- timeout. Signed-off-by: NHelmut Schaa <helmut.schaa@googlemail.com> Signed-off-by: NJohn W.

No hw/driver actually supports more than four queues right now, and we allocate a number of things per queue which means we waste a bit of memory. Reduce the maximum number to four to accurately reflect what we do (and need for QoS). Even if we had hardware supporting more queues we couldn't take advantage of that right now anyway.

The scan capability added to cfg80211/nl80211 introduced a dependency on nl80211 by cfg80211. We can thus no longer have just cfg80211 without nl80211. Specifically, cfg80211_scan_done() calls nl80211_send_scan_aborted() or nl80211_send_scan_done(). Now we remove the option for user to select nl80211. It will always be compiled if user selects cfg80211. Signed-off-by: NReinette Chatre <reinette.chatre@intel.com> Signed-off-by: NJohn W. Linville <linville@tuxdriver.com>

When there are no free snums, UCC ethernet should gracefully fail, but currently it oopses this way: # ifconfig eth0 up fill_init_enet_entries: Can not get SNUM. ucc_geth_startup: Can not fill p_init_enet_param_shadow. eth0: Cannot configure net device, aborting.

If we add a check to the ucc_geth_stop(), then another oops pops up: Unable to handle kernel paging request for data at address 0x00000004 Faulting instruction address: 0xc01b46a4 Oops: Kernel access of bad area, sig: 11 [#1] [...] NIP [c01b46a4] adjust_link+0x20/0x1b4 LR [c01b770c] phy_state_machine+0xdc/0x44c Call Trace: [ef83bf10] [c021b388] linkwatch_schedule_work+0x74/0xf8 (unreliable) [ef83bf40] [c01b770c] phy_state_machine+0xdc/0x44c [ef83bf60] [c004c13c] run_workqueue+0xb8/0x148 [ef83bf90] [c004c870] worker_thread+0x70/0xd0 [ef83bfd0] [c00505fc] kthread+0x48/0x84 [ef83bff0] [c000f464] kernel_thread+0x4c/0x68 [...] That one happens because ucc_geth_stop() does not call phy_disconnect() and so phylib state machine is running without any idea that a MAC has just died. Also, when device tree specifies fixed-link, and CONFIG_FIXED_PHY is disabled, we'll get this oops: 0:01 not found eth2: Could not attach to PHY eth2: Cannot initialize PHY, aborting.

This patch fixes all three oopses simply by rearranging some code: - In ucc_geth_open(): move init_phy() call to the beginning, so that we only call ucc_geth_stop() with a PHY attached; - Move phy_disconnect() call from ucc_geth_close() to ucc_geth_stop(), so that we'll always disconnect the PHY.

The inline function skb_gro_mac_header defined in include/linux/netdevice.h makes use of page_address(). Depending on configuration options, the latter is either defined as a macro or is declared as a function in another header file, namely include/linux/mm.h. However, include/linux/netdevice.h does not include include/linux/mm.h. On MIPS, this has produced the following build error: CC kernel/sysctl_check.o In file included from include/linux/icmpv6.h:173, from include/linux/ipv6.h:208, from include/net/ip_vs.h:26, from kernel/sysctl_check.c:6: include/linux/netdevice.h: In function 'skb_gro_mac_header': include/linux/netdevice.h:1132: error: implicit declaration of function 'page_address' include/linux/netdevice.h:1133: warning: pointer/integer type mismatch in conditional expression make[1]: *** [kernel/sysctl_check.o] Error 1 make: *** [kernel] Error 2 The patch adds the missing include and fixes the build error.
