commit b26bdde5 upstream. When loading encrypted-keys module, if the last check of aes_get_sizes() in init_encrypted() fails, the driver just returns an error without unregistering its key type. This results in the stale entry in the list. In addition to memory leaks, this leads to a kernel crash when registering a new key type later. This patch fixes the problem by swapping the calls of aes_get_sizes() and register_key_type(), and releasing resources properly at the error paths.

commit 66139a48 upstream. In snd_usbmidi_error_timer(), the driver tries to resubmit MIDI input URBs to reactivate the MIDI stream, but this causes the error when some of URBs are still pending like: WARNING: CPU: 0 PID: 0 at ../drivers/usb/core/urb.c:339 usb_submit_urb+0x5f/0x70() URB ef705c40 submitted while active CPU: 0 PID: 0 Comm: swapper/0 Not tainted 3.16.6-2-desktop #1 Hardware name: FOXCONN TPS01/TPS01, BIOS 080015 03/23/2010 c0984bfa f4009ed4 c078deaf f4009ee4 c024c884 c09a135c f4009f00 00000000 c0984bfa 00000153 c061ac4f c061ac4f 00000009 00000001 ef705c40 e854d1c0 f4009eec c024c8d3 00000009 f4009ee4 c09a135c f4009f00 f4009f04 c061ac4f Call Trace: [<c0205df6>] try_stack_unwind+0x156/0x170 [<c020482a>] dump_trace+0x5a/0x1b0 [<c0205e56>] show_trace_log_lvl+0x46/0x50 [<c02049d1>] show_stack_log_lvl+0x51/0xe0 [<c0205eb7>] show_stack+0x27/0x50 [<c078deaf>] dump_stack+0x45/0x65 [<c024c884>] warn_slowpath_common+0x84/0xa0 [<c024c8d3>] warn_slowpath_fmt+0x33/0x40 [<c061ac4f>] usb_submit_urb+0x5f/0x70 [<f7974104>] snd_usbmidi_submit_urb+0x14/0x60 [snd_usbmidi_lib] [<f797483a>] snd_usbmidi_error_timer+0x6a/0xa0 [snd_usbmidi_lib] [<c02570c0>] call_timer_fn+0x30/0x130 [<c0257442>] run_timer_softirq+0x1c2/0x260 [<c0251493>] __do_softirq+0xc3/0x270 [<c0204732>] do_softirq_own_stack+0x22/0x30 [<c025186d>] irq_exit+0x8d/0xa0 [<c0795228>] smp_apic_timer_interrupt+0x38/0x50 [<c0794a3c>] apic_timer_interrupt+0x34/0x3c [<c0673d9e>] cpuidle_enter_state+0x3e/0xd0 [<c028bb8d>] cpu_idle_loop+0x29d/0x3e0 [<c028bd23>] cpu_startup_entry+0x53/0x60 [<c0bfac1e>] start_kernel+0x415/0x41a For avoiding these errors, check the pending URBs and skip resubmitting such ones.

commit 0542f17b upstream. The rule is simple. Don't allow anything that wouldn't be allowed without unprivileged mappings. It was previously overlooked that establishing gid mappings would allow dropping groups and potentially gaining permission to files and directories that had lesser permissions for a specific group than for all other users. This is the rule needed to fix CVE-2014-8989 and prevent any other security issues with new_idmap_permitted. The reason for this rule is that the unix permission model is old and there are programs out there somewhere that take advantage of every little corner of it. So allowing a uid or gid mapping to be established without privielge that would allow anything that would not be allowed without that mapping will result in expectations from some code somewhere being violated. Violated expectations about the behavior of the OS is a long way to say a security issue. Signed-off-by:

commit 7ff4d90b upstream. Today there are 3 instances of setgroups and due to an oversight their permission checking has diverged. Add a common function so that they may all share the same permission checking code. This corrects the current oversight in the current permission checks and adds a helper to avoid this in the future. A user namespace security fix will update this new helper, shortly. Signed-off-by:

commit 0b46b8a7 upstream. This is a bug fix for using physical arch timers when the arch_timer_use_virtual boolean is false. It restores the arch_counter_get_cntpct() function after removal in 0d651e4e "clocksource: arch_timer: use virtual counters" We need this on certain ARMv7 systems which are architected like this: * The firmware doesn't know and doesn't care about hypervisor mode and we don't want to add the complexity of hypervisor there. * The firmware isn't involved in SMP bringup or resume. * The ARCH timer come up with an uninitialized offset between the virtual and physical counters. Each core gets a different random offset. * The device boots in "Secure SVC" mode. * Nothing has touched the reset value of CNTHCTL.PL1PCEN or CNTHCTL.PL1PCTEN (both default to 1 at reset) One example of such as system is RK3288 where it is much simpler to use the physical counter since there's nobody managing the offset and each time a core goes down and comes back up it will get reinitialized to some other random value.

commit ac030860 upstream. The end timer is used for switching back from repeat code timings when no repeat codes have been received for a certain amount of time. When the protocol is changed, the end timer is deleted synchronously with del_timer_sync(), however this takes place while holding the main spin lock, and the timer handler also needs to acquire the spin lock. This opens the possibility of a deadlock on an SMP system if the protocol is changed just as the repeat timer is expiring. One CPU could end up in img_ir_set_decoder() holding the lock and waiting for the end timer to complete, while the other CPU is stuck in the timer handler spinning on the lock held by the first CPU. Lockdep also spots a possible lock inversion in the same code, since img_ir_set_decoder() acquires the img-ir lock before the timer lock, but the timer handler will try and acquire them the other way around: ========================================================= [ INFO: possible irq lock inversion dependency detected ] 3.18.0-rc5+ #957 Not tainted --------------------------------------------------------- swapper/0/0 just changed the state of lock: (((&hw->end_timer))){+.-...}, at: [<4006ae5c>] _call_timer_fn+0x0/0xfc but this lock was taken by another, HARDIRQ-safe lock in the past: (&(&priv->lock)->rlock#2){-.....} and interrupts could create inverse lock ordering between them. other info that might help us debug this: Possible interrupt unsafe locking scenario: CPU0 CPU1 ---- ---- lock(((&hw->end_timer))); local_irq_disable(); lock(&(&priv->lock)->rlock#2); lock(((&hw->end_timer))); <Interrupt> lock(&(&priv->lock)->rlock#2); *** DEADLOCK *** This is fixed by releasing the main spin lock while performing the del_timer_sync() call.

commit ea0de4ec upstream. A problem was found on Polaris where if the unit it booted via the power button on the infrared remote then the next button press on the remote would return the key code used to power on the unit. The sequence is: - The polaris powered off but with the powerdown controller (PDC) block still powered. - Press power key on remote, IR block receives the key. - Kernel starts, IR code is in IMG_IR_DATA_x but neither IMG_IR_RXDVAL or IMG_IR_RXDVALD2 are set. - Wait any amount of time. - Press any key. - IMG_IR_RXDVAL or IMG_IR_RXDVALD2 is set but IMG_IR_DATA_x is unchanged since the powerup key data was never read. This is worked around by always reading the IMG_IR_DATA_x in img_ir_set_decoder(), rather than only when the IMG_IR_RXDVAL or IMG_IR_RXDVALD2 bit is set. Signed-off-by:

commit c884227e upstream. On x86 truncation cannot occur because config XEN depends on X86_64 || (X86_32 && X86_PAE). On ARM truncation can occur without CONFIG_ARM_LPAE, when the dma operation involves foreign grants. However in that case the physical address returned by xen_bus_to_phys is actually invalid (there is no mfn to pfn tracking for foreign grants on ARM) and it is not used. Signed-off-by:

commit 108cef3a upstream. It is critical that fetch_block() and handle_stripe_dirtying() are consistent in their analysis of what needs to be loaded. Otherwise raid5 can wait forever for a block that won't be loaded. Currently when writing to a RAID5 that is resyncing, to a location beyond the resync offset, handle_stripe_dirtying chooses a reconstruct-write cycle, but fetch_block() assumes a read-modify-write, and a lockup can happen. So treat that case just like RAID6, just as we do in handle_stripe_dirtying. RAID6 always does reconstruct-write. This bug was introduced when the behaviour of handle_stripe_dirtying was changed in 3.7, so the patch is suitable for any kernel since, though it will need careful merging for some versions.

commit b2f5d4dc upstream. Forced unmount affects not just the mount namespace but the underlying superblock as well. Restrict forced unmount to the global root user for now. Otherwise it becomes possible a user in a less privileged mount namespace to force the shutdown of a superblock of a filesystem in a more privileged mount namespace, allowing a DOS attack on root.

commit 445559cd upstream.

commit 8bfbe2de upstream. Commit 19e2ad6a ("n_tty: Remove overflow tests from receive_buf() path") moved the increment of read_head into the arguments list of read_buf_addr(). Function calls represent a sequence point in C. Therefore read_head is incremented before the character c is placed in the buffer. Since the circular read buffer is a lock-less design since commit 6d76bd26 ("n_tty: Make N_TTY ldisc receive path lockless"), this creates a race condition that leads to communication errors. This patch modifies the code to increment read_head _after_ the data is placed in the buffer and thus fixes the race for non-SMP machines. To fix the problem for SMP machines, memory barriers must be added in a separate patch. Signed-off-by:

commit 66dfd101 upstream. Commit f1d2736c (mmc: dw_mmc: control card read threshold) added dw_mci_ctrl_rd_thld() with an unconditional write to the CDTHRCTL register at offset 0x100. However before version 240a, the FIFO region started at 0x100, so the write messes with the FIFO and completely breaks the driver. If the version id < 240A, return early from dw_mci_ctl_rd_thld() so as not to hit this problem. Fixes: f1d2736c (mmc: dw_mmc: control card read threshold) Signed-off-by:

commit 1ff383a4 upstream. This patch adds waiting until transmit buffer and shifter will be empty before clock disabling. Without this fix it's possible to have clock disabled while data was not transmited yet, which causes unproper state of TX line and problems in following data transfers. Signed-off-by:
