2013-10-01ieee80211: fix vht cap definitionsEliad Peller
VHT_CAP_BEAMFORMER_ANTENNAS cap is actually defined in the draft as VHT_CAP_BEAMFORMEE_STS_MAX, and its size is 3 bits long. VHT_CAP_SOUNDING_DIMENSIONS is also 3 bits long. Fix the definitions and change the cap masking accordingly. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2013-10-01drm: Code stereo layouts as an enum rather than a bit fieldDamien Lespiau
This allows us to use fewer bits in the mode structure, leaving room for future work while allowing more stereo layouts types than we could have ever dreamt of. I also exposed the previously private DRM_MODE_FLAG_3D_MASK to set in stone that we are using 5 bits for the stereo layout enum, reserving 32 values. Even with that reservation, we gain 3 bits from the previous encoding. The code adding the mandatory stereo modes needeed to be adapted as it was relying or being able to or stereo layouts together.

2013-10-01drm: Implement timings adjustments for frame packingDamien Lespiau
When using the frame packing and a single big framebuffer, some hardware requires that we do everything like if we were scanning out the big buffer itself.

2013-10-01drm: Add a STEREO_3D capability to the SET_CLIENT_CAP ioctlDamien Lespiau
This capability allows user space to control the delivery of modes with the 3D flags set. This is to not play games with current user space users not knowing anything about stereo 3D flags and that could try to set a mode with one or several of those bits set. So, the plan is to remove the stereo modes from the list of modes we give to DRM clients by default, and let them through if we are being told otherwise. stereo_allowed is bound to the drm_file structure to make it a per-client setting, not a global one. v2: Replace clearing 3D flags by discarding the stereo modes now that they are regular modes. v3: SET_CAP -> SET_CLIENT_CAP rename (Chris Wilson) Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Damien Lespiau <damien.lespiau@intel.com> Acked-by: Dave Airlie <airlied@gmail.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2013-09-30mm: avoid reinserting isolated balloon pages into LRU listsRafael Aquini
Isolated balloon pages can wrongly end up in LRU lists when migrate_pages() finishes its round without draining all the isolated page list. The same issue can happen when reclaim_clean_pages_from_list() tries to reclaim pages from an isolated page list, before migration, in the CMA path. Such balloon page leak opens a race window against LRU lists shrinkers that leads us to the following kernel panic: BUG: unable to handle kernel NULL pointer dereference at 0000000000000028 IP: [<ffffffff810c2625>] shrink_page_list+0x24e/0x897 PGD 3cda2067 PUD 3d713067 PMD 0 Oops: 0000 [#1] SMP CPU: 0 PID: 340 Comm: kswapd0 Not tainted 3.12.0-rc1-22626-g4367597 #87 Hardware name: Bochs Bochs, BIOS Bochs 01/01/2011 RIP: shrink_page_list+0x24e/0x897 RSP: 0000:ffff88003da499b8 EFLAGS: 00010286 RAX: 0000000000000000 RBX: ffff88003e82bd60 RCX: 00000000000657d5 RDX: 0000000000000000 RSI: 000000000000031f RDI: ffff88003e82bd40 RBP: ffff88003da49ab0 R08: 0000000000000001 R09: 0000000081121a45 R10: ffffffff81121a45 R11: ffff88003c4a9a28 R12: ffff88003e82bd40 R13: ffff88003da0e800 R14: 0000000000000001 R15: ffff88003da49d58 FS: 0000000000000000(0000) GS:ffff88003fc00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00000000067d9000 CR3: 000000003ace5000 CR4: 00000000000407b0 Call Trace: shrink_inactive_list+0x240/0x3de shrink_lruvec+0x3e0/0x566 __shrink_zone+0x94/0x178 shrink_zone+0x3a/0x82 balance_pgdat+0x32a/0x4c2 kswapd+0x2f0/0x372 kthread+0xa2/0xaa ret_from_fork+0x7c/0xb0 Code: 80 7d 8f 01 48 83 95 68 ff ff ff 00 4c 89 e7 e8 5a 7b 00 00 48 85 c0 49 89 c5 75 08 80 7d 8f 00 74 3e eb 31 48 8b 80 18 01 00 00 <48> 8b 74 0d 48 8b 78 30 be 02 00 00 00 ff d2 eb RIP [<ffffffff810c2625>] shrink_page_list+0x24e/0x897 RSP <ffff88003da499b8> CR2: 0000000000000028 ---[ end trace 703d2451af6ffbfd ]--- Kernel panic - not syncing: Fatal exception This patch fixes the issue, by assuring the proper tests are made at putback_movable_pages() & reclaim_clean_pages_from_list() to avoid isolated balloon pages being wrongly reinserted in LRU lists.

Almost every cpufreq driver is required to validate its frequency table with: cpufreq_frequency_table_cpuinfo() and then expose it to cpufreq core with: cpufreq_frequency_table_get_attr(). This patch creates another helper routine cpufreq_table_validate_and_show() that will do both these steps in a single call and will return 0 for success, error otherwise. This also fixes potential bugs in cpufreq drivers where people have called cpufreq_frequency_table_get_attr() before calling cpufreq_frequency_table_cpuinfo(), as the later may fail.

2013-09-30hotplug, powerpc, x86: Remove cpu_hotplug_driver_lock()Toshi Kani
cpu_hotplug_driver_lock() serializes CPU online/offline operations when ARCH_CPU_PROBE_RELEASE is set. This lock interface is no longer necessary with the following reason: - lock_device_hotplug() now protects CPU online/offline operations, including the probe & release interfaces enabled by ARCH_CPU_PROBE_RELEASE. The use of cpu_hotplug_driver_lock() is redundant. - cpu_hotplug_driver_lock() is only valid when ARCH_CPU_PROBE_RELEASE is defined, which is misleading and is only enabled on powerpc. This patch removes the cpu_hotplug_driver_lock() interface. As a result, ARCH_CPU_PROBE_RELEASE only enables / disables the cpu probe & release interface as intended. There is no functional change in this patch. Signed-off-by: Toshi Kani <toshi.kani@hp.com> Reviewed-by: Nathan Fontenot <nfont@linux.vnet.ibm.com> Signed-off-by: Rafael J.

2013-09-30netfilter: synproxy: fix BUG_ON triggered by corrupt TCP packetsPatrick McHardy
TCP packets hitting the SYN proxy through the SYNPROXY target are not validated by TCP conntrack. When th->doff is below 5, an underflow happens when calculating the options length, causing skb_header_pointer() to return NULL and triggering the BUG_ON(). Handle this case gracefully by checking for NULL instead of using BUG_ON().

2013-09-30KVM: Convert kvm_lock back to non-raw spinlockPaolo Bonzini
In commit e935b8372cf8 ("KVM: Convert kvm_lock to raw_spinlock"), the kvm_lock was made a raw lock. However, the kvm mmu_shrink() function tries to grab the (non-raw) mmu_lock within the scope of the raw locked kvm_lock being held. This leads to the following: BUG: sleeping function called from invalid context at kernel/rtmutex.c:659 in_atomic(): 1, irqs_disabled(): 0, pid: 55, name: kswapd0 Preemption disabled at:[<ffffffffa0376eac>] mmu_shrink+0x5c/0x1b0 [kvm] Pid: 55, comm: kswapd0 Not tainted 3.4.34_preempt-rt Call Trace: [<ffffffff8106f2ad>] __might_sleep+0xfd/0x160 [<ffffffff817d8d64>] rt_spin_lock+0x24/0x50 [<ffffffffa0376f3c>] mmu_shrink+0xec/0x1b0 [kvm] [<ffffffff8111455d>] shrink_slab+0x17d/0x3a0 [<ffffffff81151f00>] ? mem_cgroup_iter+0x130/0x260 [<ffffffff8111824a>] balance_pgdat+0x54a/0x730 [<ffffffff8111fe47>] ? set_pgdat_percpu_threshold+0xa7/0xd0 [<ffffffff811185bf>] kswapd+0x18f/0x490 [<ffffffff81070961>] ? get_parent_ip+0x11/0x50 [<ffffffff81061970>] ? __init_waitqueue_head+0x50/0x50 [<ffffffff81118430>] ? balance_pgdat+0x730/0x730 [<ffffffff81060d2b>] kthread+0xdb/0xe0 [<ffffffff8106e122>] ? finish_task_switch+0x52/0x100 [<ffffffff817e1e94>] kernel_thread_helper+0x4/0x10 [<ffffffff81060c50>] ? __init_kthread_worker+0x After the previous patch, kvm_lock need not be a raw spinlock anymore, so change it back.
