2013-06-25iwlwifi: always use 'rxq' as RX queue struct nameJohannes Berg1-13/+15

2013-06-25iwlwifi: pcie: rework RX buffer list init and freeingJohannes Berg1-17/+26
The PCIe code has an array of buffer descriptors (RXBs) that have pages and DMA mappings attached. In regular use, the array isn't used and the buffers are either on the hardware receive queue or the rx_free/rx_used lists for recycling. Occasionally, during module unload, we'd see a warning from this: WARNING: at lib/list_debug.c:32 __list_add+0x91/0xa0() list_add corruption. prev->next should be next (c31c98cc), but was c31c80bc. (prev=c31c80bc). Pid: 519, comm: rmmod Tainted: G W O 3.4.24-dev #3 Call Trace: [<c10335b2>] warn_slowpath_common+0x72/0xa0 [<c1033683>] warn_slowpath_fmt+0x33/0x40 [<c12e31d1>] __list_add+0x91/0xa0 [<fdf2083c>] iwl_pcie_rxq_free_rbs+0xcc/0xe0 [iwlwifi] [<fdf21b3f>] iwl_pcie_rx_free+0x3f/0x210 [iwlwifi] [<fdf2dd7a>] iwl_trans_pcie_free+0x2a/0x90 [iwlwifi] The reason for this seems to be that in iwl_pcie_rxq_free_rbs() we use the array to free all buffers (the hardware receive queue isn't in use any more at this point). The function also adds all buffers to rx_used because it's also used during initialisation (when no freeing happens.) This can cause the warning because it may add entries to the list that are already on it. Luckily, this is harmless because it can only happen when the entire data structure is freed anyway, since during init both lists are initialized from scratch. Disentangle this code and treat init and free separately. During init we just need to put them onto the list after freeing all buffers (for switching between 4k/8k buffers); during free no list manipulations are necessary at all.

2013-06-25iwlwifi: mvm: Change the settings of AP beacon timeIlan Peer1-5/+51
In case that an AP/GO interface is started while there is a station/P2P client associated, need to make sure that the AP/GO beacon time is far enough from the station's one in oder to allow the station to receive the DTIM beacons and the following traffic etc. To resolve this, when the AP is started, check if there is an active station interface, and guarantee that the AP/GO TBTT is far enough from the station one.

2013-06-24cw1200: Fix up a large pile of sparse warningsSolomon Peachy10-97/+102
Most of these relate to endianness problems, and are purely cosmetic. But a couple of them were legit -- listen interval parsing and some of the rate selection code would malfunction on BE systems. There's still one cosmetic warning remaining, in the (admittedly) ugly code in cw1200_spi.c. It's there because the hardware needs 16-bit SPI transfers, but many SPI controllers only operate 8 bits at a time. If there's a cleaner way of handling this, I'm all ears.

Conflicts: drivers/net/wireless/ath/ath9k/Kconfig drivers/net/xen-netback/netback.c net/batman-adv/bat_iv_ogm.c net/wireless/nl80211.c The ath9k Kconfig conflict was a change of a Kconfig option name right next to the deletion of another option. The xen-netback conflict was overlapping changes involving the handling of the notify list in xen_netbk_rx_action(). Batman conflict resolution provided by Antonio Quartulli, basically keep everything in both conflict hunks. The nl80211 conflict is a little more involved. In 'net' we added a dynamic memory allocation to nl80211_dump_wiphy() to fix a race that Linus reported. Meanwhile in 'net-next' the handlers were converted to use pre and post doit handlers which use a flag to determine whether to hold the RTNL mutex around the operation. However, the dump handlers to not use this logic. Instead they have to explicitly do the locking. There were apparent bugs in the conversion of nl80211_dump_wiphy() in that we were not dropping the RTNL mutex in all the return paths, and it seems we very much should be doing so. So I fixed that whilst handling the overlapping changes. To simplify the initial returns, I take the RTNL mutex after we try to allocate 'tb'. Signed-off-by: David S. Miller <[email protected]>
