The bonding driver initializes some data structures only after its ndo_open routine is called. Among them is the initalization of the alb tx and rx hash locks. So if we add or remove a slave without first opening the bond master device, we run the risk of trying to lock/unlock a spinlock that has garbage for data in it, which results in our above softlock. Note that sometimes this works, because in many cases an unlocked spinlock has the raw_lock parameter initialized to zero (meaning that the kzalloc of the net_device private data is equivalent to calling spin_lock_init), but thats not true in all cases, and we aren't guaranteed that condition, so we need to pass the relevant spinlocks through the spin_lock_init function. Fix it by moving the spin_lock_init calls for the tx and rx hashtable locks to the ndo_init path, so they are ready for use by the bond_store_slaves path. Change notes: v2) Based on conversation with Jay and Nicolas it seems that the ability to enslave devices while the bond master is down should be safe to do. As such this is an outlier bug, and so instead we'll just initalize the errant spinlocks in the init path rather than the open path, solving the problem. We'll also remove the warnings about the bond being down during enslave operations, since it should be safe v3) Fix spelling error Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Reported-by: jtluka@redhat.com CC: Jay Vosburgh <fubar@us.ibm.com> CC: Andy Gospodarek <andy@greyhouse.net> CC: nicolas.2p.debian@gmail.com CC: "David S.

* net: hold rtnl again in dump callbacksEric Dumazet2011-05-25
| | | | | | | | | | | | | | | | | Commit e67f88dd12f6 (dont hold rtnl mutex during netlink dump callbacks) missed fact that rtnl_fill_ifinfo() must be called with rtnl held. Because of possible deadlocks between two mutexes (cb_mutex and rtnl), its not easy to solve this problem, so revert this part of the patch. It also forgot one rcu_read_unlock() in FIB dump_rules() Add one ASSERT_RTNL() in rtnl_fill_ifinfo() to remind us the rule.

* via-velocity: don't annotate MAC registers as packedUlrich Hecht2011-05-25
| | | | | | | | | | | | | | | | On ARM, memory accesses through packed pointers behave in unexpected ways in GCC releases 4.3 and higher; see https://lkml.org/lkml/2011/2/2/163 for discussion. In this particular case, 32-bit I/O registers are accessed bytewise, causing incorrect setting of the DMA address registers which in turn leads to an error interrupt storm that brings the system to a halt. Since the mac_regs structure does not need any packing anyway, this patch simply removes the attribute to fix the issue. Signed-off-by: Ulrich Hecht <uli@suse.de> Signed-off-by: David S.

| | * mwifiex: reduce CPU usage by tracking highest_queued_prioMarc Yang2011-05-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds highest_queued_prio to track priority of packets as they are enqueued so that mwifiex_wmm_get_highest_priolist_ptr() starts checking at the first level where we have packets, instead of the highest. The function also lowers priority value to the level where first packet is found. Signed-off-by: Marc Yang <yangyang@marvell.com> Signed-off-by: Bing Zhao <bzhao@marvell.com> Signed-off-by: John W.

| | * net: rfkill: add generic gpio rfkill driverRhyland Klein2011-05-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a new generic gpio rfkill driver to support rfkill switches which are controlled by gpios. The driver also supports passing in data about the clock for the radio, so that when rfkill is blocking, it can disable the clock. This driver assumes platform data is passed from the board files to configure it for specific devices.

| | * ath9k: fix ad-hoc mode beacon selectionFelix Fietkau2011-05-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In ad-hoc mode, beacon timers are configured differently compared to AP mode, and (depending on the scenario) can vary enough to make the beacon tasklet not detect slot 0 based on the TSF. Since staggered beacons are not (and cannot be) used in ad-hoc mode, it makes more sense to just hardcode slot 0 here, avoiding unnecessary TSF reads and calculations.

| | * cfg80211: Use consistent BSS matching between scan and smeJouni Malinen2011-05-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cfg80211 scan code adds separate BSS entries if the same BSS shows up on multiple channels. However, sme implementation does not use the frequency when fetching the BSS entry. Fix this by adding channel information to cfg80211_roamed() and include it in cfg80211_get_bss() calls. Please note that drivers using cfg80211_roamed() need to be modified to fully implement this fix. This commit includes only minimal changes to avoid compilation issues; it maintains the old (broken) behavior for most drivers. ath6kl was the only one that I could test, so I updated it to provide the operating frequency in the roamed event.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The changes that were made to rtl8192ce when rtl8192cu was added broke HT40. The errors included a typo in rtlwifi, a missing routine in rtl8192ce and a missing callback of that routine in rtl8192c-common. This patch fixes the regression reported in Bug #35082.

| | * mac80211: annotate and fix RCU in mesh codeJohannes Berg2011-05-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds proper RCU annotations to the mesh path table code, and fixes a number of bugs in the code that I found while checking the sparse warnings I got as a result of the annotations. Some things like the changes in mesh_path_add() or mesh_pathtbl_init() only serve to shut up sparse, but other changes like the changes surrounding the for_each_mesh_entry() macro fix real RCU bugs in the code.
