2016-08-03drm: i915: fix build when DEBUG_FS is disabledLinus Torvalds
This clearly had never gotten tested, probably because you need a fairly minimal configuration in order to disable DEBUG_FS (several other options select it). The dummy inline functions that were used for the no-DEBUG_FS case were missing the argument names in the declarations. Fixes: 1dac891c1c95 ("drm/i915: Register debugfs interface last") Reported-and-tested-by: Jörg Otte <jrg.otte@gmail.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2016-08-04um: Setup physical memory in setup_arch()Richard Weinberger
Currently UML sets up physical memory very early, long before setup_arch() was called by the kernel main function. This can cause problems when code paths in UML's memory setup code assume that the kernel is already running. i.e. when kmemleak is enabled it will evaluate current() in free_bootmem(). That early current() is undefined and UML explodes. Solve the problem by setting up physical memory in setup_arch(), at this stage the kernel has materialized and basic infrastructure such as current() works.

2016-08-03qlcnic: fix data structure corruption in async mbx command handlingManish Chopra
This patch fixes a data structure corruption bug in the SRIOV VF mailbox handler code. While handling mailbox commands from the atomic context, driver is accessing and updating qlcnic_async_work_list_struct entry fields in the async work list. These fields could be concurrently accessed by the work function resulting in data corruption. This patch restructures async mbx command handling by using a separate async command list instead of using a list of work_struct structures. A single work_struct is used to schedule and handle the async commands with proper locking mechanism.

2016-08-03bpf: fix method of PTR_TO_PACKET reg id generationJakub Kicinski
Using per-register incrementing ID can lead to find_good_pkt_pointers() confusing registers which have completely different values. Consider example: 0: (bf) r6 = r1 1: (61) r8 = *(u32 *)(r6 +76) 2: (61) r0 = *(u32 *)(r6 +80) 3: (bf) r7 = r8 4: (07) r8 += 32 5: (2d) if r8 > r0 goto pc+9 R0=pkt_end R1=ctx R6=ctx R7=pkt(id=0,off=0,r=32) R8=pkt(id=0,off=32,r=32) R10=fp 6: (bf) r8 = r7 7: (bf) r9 = r7 8: (71) r1 = *(u8 *)(r7 +0) 9: (0f) r8 += r1 10: (71) r1 = *(u8 *)(r7 +1) 11: (0f) r9 += r1 12: (07) r8 += 32 13: (2d) if r8 > r0 goto pc+1 R0=pkt_end R1=inv56 R6=ctx R7=pkt(id=0,off=0,r=32) R8=pkt(id=1,off=32,r=32) R9=pkt(id=1,off=0,r=32) R10=fp 14: (71) r1 = *(u8 *)(r9 +16) 15: (b7) r7 = 0 16: (bf) r0 = r7 17: (95) exit We need to get a UNKNOWN_VALUE with imm to force id generation so lines 0-5 make r7 a valid packet pointer. We then read two different bytes from the packet and add them to copies of the constructed packet pointer. r8 (line 9) and r9 (line 11) will get the same id of 1, independently. When either of them is validated (line 13) - find_good_pkt_pointers() will also mark the other as safe. This leads to access on line 14 being mistakenly considered safe.

2016-08-03net: xgene: fix maybe-uninitialized variableArnd Bergmann
Building with -Wmaybe-uninitialized shows a potential use of an uninitialized variable: drivers/net/ethernet/apm/xgene/xgene_enet_hw.c: In function 'xgene_enet_phy_connect': drivers/net/ethernet/apm/xgene/xgene_enet_hw.c:802:23: warning: 'phy_dev' may be used uninitialized in this function [-Wmaybe-uninitialized] Although the compiler correctly identified this based on the function, the current code is still safe as long dev->of_node is non-NULL for the case of CONFIG_ACPI=n, which is currently the case. The warning is now disabled by default, but still appears when building with W=1, and other build test tools should be able to detect it as well. Adding an #else clause here makes the code more robust and makes it clear to the compiler that this cannot happen.

2016-08-03cachefiles: Fix race between inactivating and culling a cache objectDavid Howells
There's a race between cachefiles_mark_object_inactive() and cachefiles_cull(): (1) cachefiles_cull() can't delete a backing file until the cache object is marked inactive, but as soon as that's the case it's fair game. (2) cachefiles_mark_object_inactive() marks the object as being inactive and *only then* reads the i_blocks on the backing inode - but cachefiles_cull() might've managed to delete it by this point. Fix this by making sure cachefiles_mark_object_inactive() gets any data it needs from the backing inode before deactivating the object. Without this, the following oops may occur: BUG: unable to handle kernel NULL pointer dereference at 0000000000000098 IP: [<ffffffffa06c5cc1>] cachefiles_mark_object_inactive+0x61/0xb0 [cachefiles] ...

The patch that this was preparing for made it into neither v4.7 nor v4.8, so we should back this out as well to avoid the opposite warning: arch/arm/configs/aspeed_g5_defconfig:62:warning: symbol value '1' invalid for PRINTK_TIME arch/arm/configs/aspeed_g4_defconfig:61:warning: symbol value '1' invalid for PRINTK_TIME Sorry for not catching this earlier.

Commit a168b8f1cde6 ("MIPS: mm: Add MIPS R6 instruction encodings") added an incorrect definition of the redefined MIPSr6 cache instruction. Executing any kernel code including this instuction results in a reserved instruction exception and kernel panic. Fix the instruction definition.

2016-08-03mac80211: mesh: flush stations before beacons are stoppedMaital Hahn
Some drivers (e.g. wl18xx) expect that the last stage in the de-initialization process will be stopping the beacons, similar to AP flow. Update ieee80211_stop_mesh() flow accordingly. As peers can be removed dynamically, this would not impact other drivers. Tested also on Ralink RT3572 chipset.
