2016-12-13mac80211: Use appropriate name for functions and messagesMasashi Honma
These functions drifts TSF timers, not TBTT. Signed-off-by: Masashi Honma <masashi.honma@gmail.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2016-12-13mac80211: Remove invalid flag operations in mesh TSF synchronizationMasashi Honma
mesh_sync_offset_adjust_tbtt() implements Extensible synchronization framework ([1] 13.13.2 Extensible synchronization framework). It shall not operate the flag "TBTT Adjusting subfield" ([1] 8.4.2.100.8 Mesh Capability), since it is used only for MBCA ([1] 13.13.4 Mesh beacon collision avoidance, see 13.13.4.4.3 TBTT scanning and adjustment procedures for detail). So this patch remove the flag operations.

2016-12-13rfkill: Add rfkill-any LED triggerMichał Kępień
Add a new "global" (i.e. not per-rfkill device) LED trigger, rfkill-any, which may be useful on laptops with a single "radio LED" and multiple radio transmitters. The trigger is meant to turn a LED on whenever there is at least one radio transmitter active and turn it off otherwise. This requires taking rfkill_global_mutex before calling rfkill_set_block() in rfkill_resume(): since __rfkill_any_led_trigger_event() is called from rfkill_set_block() unconditionally, each caller of the latter needs to take care of locking rfkill_global_mutex.

2016-12-13mac80211: Suppress NEW_PEER_CANDIDATE event if no roomMasashi Honma
Previously, kernel sends NEW_PEER_CANDIDATE event to user land even if the found peer does not have any room to accept other peer. This causes continuous connection trials. Signed-off-by: Masashi Honma <masashi.honma@gmail.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2016-12-13mac80211: multicast to unicast conversionMichael Braun
Add the ability for an AP (and associated VLANs) to perform multicast-to-unicast conversion for ARP, IPv4 and IPv6 frames (possibly within 802.1Q). If enabled, such frames are to be sent to each station separately, with the DA replaced by their own MAC address rather than the group address. Note that this may break certain expectations of the receiver, such as the ability to drop unicast IP packets received within multicast L2 frames, or the ability to not send ICMP destination unreachable messages for packets received in L2 multicast (which is required, but the receiver can't tell the difference if this new option is enabled.) This also doesn't implement the 802.11 DMS (directed multicast service).

2016-12-12openrisc: restore all regs on rt_sigreturnJonas Bonn
Fix signal handling for when signals are handled as the result of timers or exceptions, previous code assumed syscalls. This was noticeable with X crashing where it uses SIGALRM. This patch restores all regs before returning to userspace via _resume_userspace instead of via syscall return path. The rt_sigreturn syscall is more like a context switch than a function call; it entails a return from one context (the signal handler) to another (the process in question). For a context switch like this there are effectively no call-saved regs that remain constant across the transition.

2016-12-12openrisc: fix PTRS_PER_PGD defineStefan Kristiansson
On OpenRISC, with its 8k pages, PAGE_SHIFT is defined to be 13. That makes the expression (1UL << (PAGE_SHIFT-2)) evaluate to 2048. The correct value for PTRS_PER_PGD should be 256. Correcting the PTRS_PER_PGD define unveiled a bug in map_ram(), where PTRS_PER_PGD was used when the intent was to iterate over a set of page table entries. This patch corrects that issue as well.

2016-12-11sparc64: fix typo in pgd_clear()Kirill A. Shutemov
It really has to be pgdp, not pgd. It just happend to work since all callers have 'pgd' as an argument. Signed-off-by: Kirill A. Shutemov <kirill.shutemov@linux.intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-12-11sparc64: restore irq in error paths in iommuDan Carpenter
There are some error paths where we should restore IRQs but we don't. Fixes: bb620c3d3925 ("sparc: Make sparc64 use scalable lib/iommu-common.c functions") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-12-11sparc: leon: Fix a retry loop in leon_init_timers()Dan Carpenter
The original code causes a static checker warning because it has a continue inside a do { } while (0); loop. In that context, a continue and a break are equivalent. The intent was to go back to the start of the loop so the continue was a bug. I've added a retry label at the start and changed the continue to a goto retry. Then I removed the do { } while (0) loop and pulled the code in one indent level.

2016-12-11sparc64: make string buffers large enoughDan Carpenter
My static checker complains that if "lvl" is ULONG_MAX (this is 64 bit) then some of the strings will overflow. I don't know if that's possible but it seems simple enough to make the buffers slightly larger. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: David S.

Pull MIPS fixes from Ralf Baechle: "Two more MIPS fixes for 4.9: - RTC: Return -ENODEV so an external RTC will be tried - Fix mask of GPE frequency These two have been tested on Imagination's automated test system and also both received positive reviews on the linux-mips mailing list" * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: MIPS: Lantiq: Fix mask of GPE frequency MIPS: Return -ENODEV from weak implementation of rtc_mips_set_time
