death_by_timeout() might delete a conntrack from hash list and insert it in dying list. nf_ct_delete_from_lists(ct); nf_ct_insert_dying_list(ct); I believe a (lockless) reader could *catch* ct while doing a lookup and miss the end of its chain. (nulls lookup algo must check the null value at the end of lookup and should restart if the null value is not the expected one. cf Documentation/RCU/rculist_nulls.txt for details) We need to change nf_conntrack_init_net() and use a different "null" value, guaranteed not being used in regular lists. Choose very large values, since hash table uses [0..size-1] null values. Signed-off-by:

Don't drop route if we're not caching I recently got a report of an oops on a route lookup. Maxime was testing what would happen if route caching was turned off (doing so by setting making rt_caching always return 0), and found that it triggered an oops. I looked at it and found that the problem stemmed from the fact that the route lookup routines were returning success from their lookup paths (which is good), but never set the **rp pointer to anything (which is bad). This happens because in rt_intern_hash, if rt_caching returns false, we call rt_drop and return 0. This almost emulates slient success. What we should be doing is assigning *rp = rt and _not_ dropping the route. This way, during slow path lookups, when we create a new route cache entry, we don't immediately discard it, rather we just don't add it into the cache hash table, but we let this one lookup use it for the purpose of this route request. Maxime has tested and reports it prevents the oops. There is still a subsequent routing issue that I'm looking into further, but I'm confident that, even if its related to this same path, this patch makes sense to take. Signed-off-by:

When I disallowed interfering with stations on non-AP interfaces, I not only forget mesh but also managed interfaces which need this for the authorized flag. Let's actually validate everything properly. This fixes an nl80211 regression introduced by the interfering, under which wpa_supplicant -Dnl80211 could not properly connect. Signed-off-by:

73ca5203 (ath5k: remove conf->beacon_int usage) removed bintval setting from ath5k_config. We need to init the interval earlier and don't touch it in add_interface anymore. Otherwise it will be set only once by upper layer through bss_info_changed but not on second and further hostap executions. We ended up having bintval 1000 which rendered the AP useless on many clients. Signed-off-by:

This information allows userspace to implement a hybrid policy where it can store the rfkill soft-blocked state in platform non-volatile storage if available, and if not then file-based storage can be used. Some users prefer platform non-volatile storage because of the behaviour when dual-booting multiple versions of Linux, or if the rfkill setting is changed in the BIOS setting screens, or if the BIOS responds to wireless-toggle hotkeys itself before the relevant platform driver has been loaded.

This will respect state changes over hibernation, e.g. if the user disables the wireless in the BIOS setup screen. It reveals an issue where ACPI silently kills the wireless on suspend. Normally, the BIOS restores the correct state from non-volatile storage on boot. But when hibernation is aborted, the wireless would remain killed. Fortunately we can work around this in the resume handler by simply writing back the same value we read from NVS. Signed-off-by:

The setting of the "persistent" flag is also made more explicit using a new rfkill_init_sw_state() function, instead of special-casing rfkill_set_sw_state() when it is called before registration. Suspend is a bit of a corner case so we try to get away without adding another hack to rfkill-input - it's going to be removed soon. If the state does change over suspend, users will simply have to prod rfkill-input twice in order to toggle the state. Userspace policy agents will be able to implement a more consistent user experience. For example, they can avoid the above problem if they toggle devices individually. Then there would be no "global state" to get out of sync. Currently there are only two rfkill drivers with persistent soft-blocked state. thinkpad-acpi already checks the software state on resume. eeepc-laptop will require modification. Signed-off-by:

Alan Jenkins authored
If we return after fiddling with the state, userspace will see the wrong state and rfkill_set_sw_state() won't work until the next call to rfkill_set_block(). At the moment rfkill_set_block() will always be called from rfkill_resume(), but this will change in future. Also, presumably the point of this test is to avoid bothering devices which may be suspended. If we don't want to call set_block(), we probably don't want to call query() either :-). Signed-off-by:

An earlier commit, 'ath9k: remove dummy PCI "retry timeout" fix', removed code that was documented to disable RETRY_TIMEOUT register (PCI reg 0x41) since it was claimed to be a no-op. However, it turns out that there are some combinations of hosts and ath9k-supported cards for which this is not a no-op (reg 0x41 has value 0x80, not 0) and this code (or something similar) is needed. In such cases, the driver may be next to unusable due to very frequent PCI FATAL interrupts from the card. Reverting the earlier commit, i.e., restoring the RETRY_TIMEOUT disabling, seems to resolve the issue. Since the removal of this code was not based on any known issue and was purely a cleanup change, the safest option here is to just revert that commit. Should there be desire to clean this up in the future, the change will need to be tested with a more complete coverage of cards and host systems. http://bugzilla.kernel.org/show_bug.cgi?id=13483 Cc: stable@kernel.org Signed-off-by:

Note the latter two are already protected by rtnl. So if iwm_reset_worker is not required in the future, the mutex can also be removed. Signed-off-by:

The iwm_if_free() is called before destroy_workqueue for isr_wq on device remove method. But if there is still some pending work in the isr_wq, the required data structures are already freed at this point. This leeds a kernel oops.

We used to do alloc_netdev and register_netdev at the same time in iwm_if_alloc. But some bus related structures will only be initialized after iwm_priv is allocated. This caused a race condition that the netdev might be registered earlier. The patch adds iwm_if_add and iwm_if_remove so that the bus layer could register the device after all initialization is done.

The Unicast Promiscious Mode (UPM) bit in the mv643xx_eth port configuration register doesn't do exactly what its name would suggest: setting this bit merely enables reception of all unicast frames with a destination address that differs from our local MAC address in bits [47:4]. In particular, it doesn't have any effect on unicast frames with a destination address that matches our MAC address in bits [47:4] -- these will still be tested against the 16-entry unicast address filter table. Therefore, if the interface is set to promiscuous mode, just setting the unicast promiscuous bit isn't enough -- we need to set all filter bits in the unicast filter table to 1 as well. Reported-by:
