2016-01-14sparc64: fix incorrect sign extension in sys_sparc64_personalityDmitry V. Levin
The value returned by sys_personality has type "long int". It is saved to a variable of type "int", which is not a problem yet because the type of task_struct->pesonality is "unsigned int". The problem is the sign extension from "int" to "long int" that happens on return from sys_sparc64_personality. For example, a userspace call personality((unsigned) -EINVAL) will result to any subsequent personality call, including absolutely harmless read-only personality(0xffffffff) call, failing with errno set to EINVAL.

2016-01-14ALSA: timer: Fix race among timer ioctlsTakashi Iwai
ALSA timer ioctls have an open race and this may lead to a use-after-free of timer instance object. A simplistic fix is to make each ioctl exclusive. We have already tread_sem for controlling the tread, and extend this as a global mutex to be applied to each ioctl. The downside is, of course, the worse concurrency. But these ioctls aren't to be parallel accessible, in anyway, so it should be fine to serialize there.

2016-01-14mac80211: Don't buffer non-bufferable MMPDUsHelmut Schaa
Non-bufferable MMPDUs are sent out to STAs even while in PS mode (for example probe responses). Applying filtered frame handling for these doesn't seem to make much sense and will only create more air utilization when the STA wakes up. Hence, apply filtered frame handling only for bufferable MMPDUs. Discovered while testing an old VOIP phone that started probing for APs while in PS mode. The mac80211/ath9k AP where the STA is associated would reply with a probe response but the phone sometimes moved to a new channel already and couldn't ack the probe response anymore. In that case mac80211 applied filtered frame handling for the un-acked probe response. Signed-off-by: Helmut Schaa <helmut.schaa@googlemail.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2016-01-14mac80211: handle sched_scan_stopped vs. hw restart raceEliad Peller
On hw restart, mac80211 might try to reconfigure already stopped sched scan, if ieee80211_sched_scan_stopped_work() wasn't scheduled yet. This in turn will keep the device driver with scheduled scan configured, while both mac80211 and cfg80211 will clear their sched scan state once the work is scheduled. Fix it by ignoring ieee80211_sched_scan_stopped() calls while in hw restart, and flush the work before starting the reconfiguration.

2016-01-14mac80211: fix PS-Poll handlingEmmanuel Grumbach
My commit below broken PS-Poll handling. In case the driver has no frames buffered, driver_release_tids will be 0, but calling find_highest_prio_tid() with 0 as a parameter is not a good idea: fls(0) - 1 = -1. This bug caused mac80211 to think that frames were buffered in the driver which in turn was confused because mac80211 was asking to release frames that were not reported to exist. On iwlwifi, this led to the WARNING below: WARNING: CPU: 0 PID: 11230 at drivers/net/wireless/intel/iwlwifi/mvm/sta.c:1733 iwl_mvm_sta_modify_sleep_tx_count+0x2af/0x320 [iwlmvm]() ffffffffc0627c60 ffff8800069b7648 ffffffff81888913 0000000000000000 0000000000000000 ffff8800069b7688 ffffffff81089d6a ffff8800069b7678 0000000000000001 ffff88003b35abf0 ffff88000698b128 ffff8800069b76d4 Call Trace: [<ffffffff81888913>] dump_stack+0x4c/0x65 [<ffffffff81089d6a>] warn_slowpath_common+0x8a/0xc0 [<ffffffff81089e5a>] warn_slowpath_null+0x1a/0x20 [<ffffffffc05f36bf>] iwl_mvm_sta_modify_sleep_tx_count+0x2af/0x320 [iwlmvm] [<ffffffffc05dae41>] iwl_mvm_mac_release_buffered_frames+0x31/0x40 [iwlmvm] [<ffffffffc045d8b6>] ieee80211_sta_ps_deliver_response+0x6e6/0xd80 [mac80211] [<ffffffffc0461296>] ieee80211_sta_ps_deliver_poll_response+0x26/0x30 [mac80211] [<ffffffffc048f743>] ieee80211_rx_handlers+0xa83/0x2900 [mac80211] [<ffffffffc04917ad>] ieee80211_prepare_and_rx_handle+0x1ed/0xa70 [mac80211] [<ffffffffc045e3d5>] ? sta_info_get_bss+0x5/0x4a0 [mac80211] [<ffffffffc04925b6>] ieee80211_rx_napi+0x586/0xcd0 [mac80211] [<ffffffffc05eaa3e>] iwl_mvm_rx_rx_mpdu+0x59e/0xc60 [iwlmvm] Fixes: 0ead2510f8ce ("mac80211: allow the driver to send EOSP when needed") Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2016-01-14Revert "mac80211_hwsim: support any address in userspace"Bob Copeland
This reverts commit cd37a90b2a417e5882414e19954eeed174aa4d29. Different userspace programs interpreted HWSIM_ATTR_ADDR_TRANSMITTER and HWSIM_ATTR_ADDR_RECEIVER differently: some expected it to be an unchanging hardware address that is tied to the radio despite which address is configured on the interface, while others expected to be a copy of the address in the frame (the configured address). The intent of the original authors is unclear. The latter interpretation doesn't really work properly with multiple vifs and broadcast frames. Also, as the TA is already in the frame, userspace programs can actually support configured addresses in the former interpretation by mapping between them and the supplied HWSIM_ATTR_ADDR_TRANSMITTER. So, in the interest of API stability, revert to the previous mode of operation and going forward use the former interpretation.

On reconfig, in case of sched_scan_req->n_scan_plans > 1, local->sched_scan_req was never cleared, although cfg80211_sched_scan_stopped_rtnl() was called, resulting in local->sched_scan_req holding a stale and preventing further scheduled scan requests.

2016-01-14regulatory: fix world regulatory domain dataJohannes Berg
The rule definitions here aren't really valid, they would be rejected if it came from userspace due to the bandwidth specified being bigger than the rule's width. This is fairly much inconsequential since the other rules around them do enable the bandwidth, but express that better using the NL80211_RRF_AUTO_BW flag.

2016-01-14mac80211: recalculate SW ROC only when neededJohannes Berg
The current (new) code recalculates the new work timeout for software remain-on-channel whenever any item started. In two of the callers of ieee80211_handle_roc_started(), this is completely pointless since they're for hardware and will skip the recalculation entirely; it's necessary only in the case of having just added a new item to the list, as in the last remaining case the recalculation had just been done. This last case, however, is also problematic - if one of the items on the list actually expires during the recalc the list iteration outside becomes corrupted and crashes. Fix this by moving the recalculation to the only place where it's required. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2016-01-14x86/cpu/amd: Remove an unneeded condition in srat_detect_node()Dan Carpenter
Originally we calculated ht_nodeid as "ht_nodeid = apicid - boot_cpu_id;" so presumably it could be negative. But after commit: 01aaea1afbcd ('x86: introduce initial apicid') we use c->initial_apicid which is an unsigned short and thus always >= 0. It causes a static checker warning to test for impossible conditions so let's remove it.

Bindings for Samsung S2M and S5M family PMICs are in mess. They are spread over different files and subdirectories in a non-consistent way. The devices and respective drivers for them share a lot in common so everything could be organized in a more readable way. Reorganize the S2MPS11/13/14/15 Device Tree bindings to match the drivers for this family of devices: - move mfd/s2mps11.txt to mfd/samsung,sec-core.txt for the main MFD driver (common for entire family), - split clock block to clock/samsung,s2mps11.txt, - split regulator block to regulator/samsung,s2mps11.txt.

2016-01-14mfd: asic3: Be sure to clamp return valueLinus Walleij
As we want gpio_chip .get() calls to be able to return negative error codes and propagate to drivers, we need to go over all drivers and make sure their return values are clamped to [0,1].
