commit cb3b3152 upstream. There has been code in place to check that the L2CAP length header matches the amount of data received, but many PDU handlers have not been checking that the data received actually matches that expected by the specific PDU. This patch adds passing the length header to the specific handler functions and ensures that those functions fail cleanly in the case of an incorrect amount of data. Signed-off-by:

commit 624483f3 upstream. While working address sanitizer for kernel I've discovered use-after-free bug in __put_anon_vma. For the last anon_vma, anon_vma->root freed before child anon_vma. Later in anon_vma_free(anon_vma) we are referencing to already freed anon_vma->root to check rwsem. This fixes it by freeing the child anon_vma before freeing anon_vma->root. Signed-off-by:

commit 8ef42ddd upstream. Not all host controller drivers have bus-suspend and bus-resume methods. When one doesn't, it will cause problems if runtime PM is enabled in the kernel. The PM core will attempt to suspend the controller's root hub, the suspend will fail because there is no bus-suspend routine, and a -EBUSY error code will be returned to the PM core. This will cause the suspend attempt to be repeated shortly thereafter, in a never-ending loop. Part of the problem is that the original error code -ENOENT gets changed to -EBUSY in usb_runtime_suspend(), on the grounds that the PM core will interpret -ENOENT as meaning that the root hub has gotten into a runtime-PM error state. While this change is appropriate for real USB devices, it's not such a good idea for a root hub. In fact, considering the root hub to be in a runtime-PM error state would not be far from the truth. Therefore this patch updates usb_runtime_suspend() so that it adjusts error codes only for non-root-hub devices. Furthermore, the patch attempts to prevent the problem from occurring in the first place by not enabling runtime PM by default for root hubs whose host controller driver doesn't have bus_suspend and bus_resume methods.

commit c03890ff upstream. A recent patch that purported to fix firmware download on big-endian machines failed to add the corresponding sparse annotation to the i2c-header. This was reported by the kbuild test robot. Adding the appropriate annotation revealed another endianess bug related to the i2c-header Size-field in a code path that is exercised when the firmware is actually being downloaded (and not just verified and left untouched unless older than the firmware at hand). This patch adds the required sparse annotation to the i2c-header and makes sure that the Size-field is sent in little-endian byte order during firmware download also on big-endian machines. Note that this patch is only compile-tested, but that there is no functional change for little-endian systems. Reported-by:

commit 192a98e2 upstream. The conversion to a fixup table for Replacer model with ALC260 in commit 20f7d928 took the wrong widget NID for COEF setups. Namely, NID 0x1a should have been used instead of NID 0x20, which is the common node for all Realtek codecs but ALC260.

commit d7500135 upstream. Input is handled in softirq context, but when pasting we may need to sleep. speakup_paste_selection() currently tries to bodge this by busy-waiting if in_atomic(), but that doesn't help because the ldisc may also sleep. For bonus breakage, speakup_paste_selection() changes the state of current, even though it's not running in process context. Move it into a work item and make sure to cancel it on exit.

commit 3991b31e upstream. If mddev->ro is set, md_to_sync will (correctly) abort. However in that case MD_RECOVERY_INTR isn't set. If a RESHAPE had been requested, then ->finish_reshape() will be called and it will think the reshape was successful even though nothing happened. Normally a resync will not be requested if ->ro is set, but if an array is stopped while a reshape is on-going, then when the array is started, the reshape will be restarted. If the array is also set read-only at this point, the reshape will instantly appear to success, resulting in data corruption. Consequently, this patch is suitable for any -stable kernel.

commit 3e030ecc upstream. When a memory error happens on an in-use page or (free and in-use) hugepage, the victim page is isolated with its refcount set to one. When you try to unpoison it later, unpoison_memory() calls put_page() for it twice in order to bring the page back to free page pool (buddy or free hugepage list). However, if another memory error occurs on the page which we are unpoisoning, memory_failure() returns without releasing the refcount which was incremented in the same call at first, which results in memory leak and unconsistent num_poisoned_pages statistics. This patch fixes it. Signed-off-by:

commit 46ce0fe9 upstream. When removing a (sibling) event we do: raw_spin_lock_irq(&ctx->lock); perf_group_detach(event); raw_spin_unlock_irq(&ctx->lock); <hole> perf_remove_from_context(event); raw_spin_lock_irq(&ctx->lock); ... raw_spin_unlock_irq(&ctx->lock); Now, assuming the event is a sibling, it will be 'unreachable' for things like ctx_sched_out() because that iterates the groups->siblings, and we just unhooked the sibling. So, if during <hole> we get ctx_sched_out(), it will miss the event and not call event_sched_out() on it, leaving it programmed on the PMU. The subsequent perf_remove_from_context() call will find the ctx is inactive and only call list_del_event() to remove the event from all other lists. Hereafter we can proceed to free the event; while still programmed! Close this hole by moving perf_group_detach() inside the same ctx->lock region(s) perf_remove_from_context() has. The condition on inherited events only in __perf_event_exit_task() is likely complete crap because non-inherited events are part of groups too and we're tearing down just the same. But leave that for another patch. Most-likely-Fixes: e03a9a55 ("perf: Change close() semantics for group events") Reported-by:

commit 0819b2e3 upstream. Vince reported that using a large sample_period (one with bit 63 set) results in wreckage since while the sample_period is fundamentally unsigned (negative periods don't make sense) the way we implement things very much rely on signed logic. So limit sample_period to 63 bits to avoid tripping over this. Reported-by:

commit 39af6b16 upstream. The perf cpu offline callback takes down all cpu context events and releases swhash->swevent_hlist. This could race with task context software event being just scheduled on this cpu via perf_swevent_add while cpu hotplug code already cleaned up event's data. The race happens in the gap between the cpu notifier code and the cpu being actually taken down. Note that only cpu ctx events are terminated in the perf cpu hotplug code. It's easily reproduced with: $ perf record -e faults perf bench sched pipe while putting one of the cpus offline: # echo 0 > /sys/devices/system/cpu/cpu1/online Console emits following warning: WARNING: CPU: 1 PID: 2845 at kernel/events/core.c:5672 perf_swevent_add+0x18d/0x1a0() Modules linked in: CPU: 1 PID: 2845 Comm: sched-pipe Tainted: G W 3.14.0+ #256 Hardware name: Intel Corporation Montevina platform/To be filled by O.E.M., BIOS AMVACRB1.86C.0066.B00.0805070703 05/07/2008 0000000000000009 ffff880077233ab8 ffffffff81665a23 0000000000200005 0000000000000000 ffff880077233af8 ffffffff8104732c 0000000000000046 ffff88007467c800 0000000000000002 ffff88007a9cf2a0 0000000000000001 Call Trace: [<ffffffff81665a23>] dump_stack+0x4f/0x7c [<ffffffff8104732c>] warn_slowpath_common+0x8c/0xc0 [<ffffffff8104737a>] warn_slowpath_null+0x1a/0x20 [<ffffffff8110fb3d>] perf_swevent_add+0x18d/0x1a0 [<ffffffff811162ae>] event_sched_in.isra.75+0x9e/0x1f0 [<ffffffff8111646a>] group_sched_in+0x6a/0x1f0 [<ffffffff81083dd5>] ? sched_clock_local+0x25/0xa0 [<ffffffff811167e6>] ctx_sched_in+0x1f6/0x450 [<ffffffff8111757b>] perf_event_sched_in+0x6b/0xa0 [<ffffffff81117a4b>] perf_event_context_sched_in+0x7b/0xc0 [<ffffffff81117ece>] __perf_event_task_sched_in+0x43e/0x460 [<ffffffff81096f1e>] ? put_lock_stats.isra.18+0xe/0x30 [<ffffffff8107b3c8>] finish_task_switch+0xb8/0x100 [<ffffffff8166a7de>] __schedule+0x30e/0xad0 [<ffffffff81172dd2>] ? pipe_read+0x3e2/0x560 [<ffffffff8166b45e>] ? preempt_schedule_irq+0x3e/0x70 [<ffffffff8166b45e>] ? preempt_schedule_irq+0x3e/0x70 [<ffffffff8166b464>] preempt_schedule_irq+0x44/0x70 [<ffffffff816707f0>] retint_kernel+0x20/0x30 [<ffffffff8109e60a>] ? lockdep_sys_exit+0x1a/0x90 [<ffffffff812a4234>] lockdep_sys_exit_thunk+0x35/0x67 [<ffffffff81679321>] ? sysret_check+0x5/0x56 Fixing this by tracking the cpu hotplug state and displaying the WARN only if current cpu is initialized properly.

commit 6227cb00 upstream. The check at the beginning of cpupri_find() makes sure that the task_pri variable does not exceed the cp->pri_to_cpu array length. But that length is CPUPRI_NR_PRIORITIES not MAX_RT_PRIO, where it will miss the last two priorities in that array. As task_pri is computed from convert_prio() which should never be bigger than CPUPRI_NR_PRIORITIES, if the check should cause a panic if it is hit. Reported-by:

commit 54a21788 upstream. The current implementation of lookup_pi_state has ambigous handling of the TID value 0 in the user space futex. We can get into the kernel even if the TID value is 0, because either there is a stale waiters bit or the owner died bit is set or we are called from the requeue_pi path or from user space just for fun. The current code avoids an explicit sanity check for pid = 0 in case that kernel internal state (waiters) are found for the user space address. This can lead to state leakage and worse under some circumstances. Handle the cases explicit: Waiter | pi_state | pi->owner | uTID | uODIED | ? [1] NULL | --- | --- | 0 | 0/1 | Valid [2] NULL | --- | --- | >0 | 0/1 | Valid [3] Found | NULL | -- | Any | 0/1 | Invalid [4] Found | Found | NULL | 0 | 1 | Valid [5] Found | Found | NULL | >0 | 1 | Invalid [6] Found | Found | task | 0 | 1 | Valid [7] Found | Found | NULL | Any | 0 | Invalid [8] Found | Found | task | ==taskTID | 0/1 | Valid [9] Found | Found | task | 0 | 0 | Invalid [10] Found | Found | task | !=taskTID | 0/1 | Invalid [1] Indicates that the kernel can acquire the futex atomically. We came came here due to a stale FUTEX_WAITERS/FUTEX_OWNER_DIED bit. [2] Valid, if TID does not belong to a kernel thread. If no matching thread is found then it indicates that the owner TID has died. [3] Invalid. The waiter is queued on a non PI futex [4] Valid state after exit_robust_list(), which sets the user space value to FUTEX_WAITERS | FUTEX_OWNER_DIED. [5] The user space value got manipulated between exit_robust_list() and exit_pi_state_list() [6] Valid state after exit_pi_state_list() which sets the new owner in the pi_state but cannot access the user space value. [7] pi_state->owner can only be NULL when the OWNER_DIED bit is set. [8] Owner and user space value match [9] There is no transient state which sets the user space TID to 0 except exit_robust_list(), but this is indicated by the FUTEX_OWNER_DIED bit. See [4] [10] There is no transient state which leaves owner and user space TID out of sync. Signed-off-by:

commit 13fbca4c upstream. If the owner died bit is set at futex_unlock_pi, we currently do not cleanup the user space futex. So the owner TID of the current owner (the unlocker) persists. That's observable inconsistant state, especially when the ownership of the pi state got transferred. Clean it up unconditionally. Signed-off-by:

commit b3eaa9fc upstream. We need to protect the atomic acquisition in the kernel against rogue user space which sets the user space futex to 0, so the kernel side acquisition succeeds while there is existing state in the kernel associated to the real owner. Verify whether the futex has waiters associated with kernel state. If it has, return -EINVAL. The state is corrupted already, so no point in cleaning it up. Subsequent calls will fail as well. Not our problem. [ tglx: Use futex_top_waiter() and explain why we do not need to try restoring the already corrupted user space state. ] Signed-off-by:

futex-prevent-requeue-pi-on-same-futex.patch futex: Forbid uaddr == uaddr2 in futex_requeue(..., requeue_pi=1) commit e9c243a5 upstream. If uaddr == uaddr2, then we have broken the rule of only requeueing from a non-pi futex to a pi futex with this call. If we attempt this, then dangling pointers may be left for rt_waiter resulting in an exploitable condition. This change brings futex_requeue() in line with futex_wait_requeue_pi() which performs the same check as per commit 6f7b0a2a ("futex: Forbid uaddr == uaddr2 in futex_wait_requeue_pi()") [ tglx: Compare the resulting keys as well, as uaddrs might be different depending on the mapping ] Fixes CVE-2014-3153.
