[ Upstream commit d683cc49 ] When encoding the NFSACL SETACL operation, reserve just the estimated size of the ACL rather than a fixed maximum. This eliminates needless zero padding on the wire that the server ignores. Fixes: ee5dc773 ('NFS: Fix "kernel BUG at fs/nfs/nfs3xdr.c:1338!"') Signed-off-by:

[ Upstream commit 530c11d4 ] The omap watchdog has the annoying behaviour that writes to most registers don't have any effect when the watchdog is already running. Quoting the AM335x reference manual: To modify the timer counter value (the WDT_WCRR register), prescaler ratio (the WDT_WCLR[4:2] PTV bit field), delay configuration value (the WDT_WDLY[31:0] DLY_VALUE bit field), or the load value (the WDT_WLDR[31:0] TIMER_LOAD bit field), the watchdog timer must be disabled by using the start/stop sequence (the WDT_WSPR register). Currently the timer is stopped in the .probe callback but still there are possibilities that yield to a situation where omap_wdt_start is entered with the timer running (e.g. when /dev/watchdog is closed without stopping and then reopened). In such a case programming the timeout silently fails! To circumvent this stop the timer before reprogramming. Assuming one of the first things the watchdog user does is setting the timeout explicitly nothing too bad should happen because this explicit setting works fine.

[ Upstream commit 3f2cee73 ] The usbfs API has a peculiar hole: Users are not allowed to reap their URBs after the device has been disconnected. There doesn't seem to be any good reason for this; it is an ad-hoc inconsistency. The patch allows users to issue the USBDEVFS_REAPURB and USBDEVFS_REAPURBNDELAY ioctls (together with their 32-bit counterparts on 64-bit systems) even after the device is gone. If no URBs are pending for a disconnected device then the ioctls will return -ENODEV rather than -EAGAIN, because obviously no new URBs will ever be able to complete. The patch also adds a new capability flag for USBDEVFS_GET_CAPABILITIES to indicate that the reap-after-disconnect feature is supported. Signed-off-by:

[ Upstream commit ab499db8 ] There was a possible race between ieee80211_reconfig() and ieee80211_delayed_tailroom_dec(). This could result in inability to transmit data if driver crashed during roaming or rekeying and subsequent skbs with insufficient tailroom appeared. This race was probably never seen in the wild because a device driver would have to crash AND recover within 0.5s which is very unlikely. I was able to prove this race exists after changing the delay to 10s locally and crashing ath10k via debugfs immediately after GTK rekeying. In case of ath10k the counter went below 0. This was harmless but other drivers which actually require tailroom (e.g. for WEP ICV or MMIC) could end up with the counter at 0 instead of >0 and introduce insufficient skb tailroom failures because mac80211 would not resize skbs appropriately anymore.

[ Upstream commit d194e5d6 ] The final version of commit 637241a9 ("kmsg: honor dmesg_restrict sysctl on /dev/kmsg") lost few hooks, as result security_syslog() are processed incorrectly: - open of /dev/kmsg checks syslog access permissions by using check_syslog_permissions() where security_syslog() is not called if dmesg_restrict is set. - syslog syscall and /proc/kmsg calls do_syslog() where security_syslog can be executed twice (inside check_syslog_permissions() and then directly in do_syslog()) With this patch security_syslog() is called once only in all syslog-related operations regardless of dmesg_restrict value.

[ Upstream commit 2528a8b8 ] bitmap_parselist("", &mask, nmaskbits) will erroneously set bit zero in the mask. The same bug is visible in cpumask_parselist() since it is layered on top of the bitmask code, e.g. if you boot with "isolcpus=", you will actually end up with cpu zero isolated. The bug was introduced in commit 4b060420 ("bitmap, irq: add smp_affinity_list interface to /proc/irq") when bitmap_parselist() was generalized to support userspace as well as kernelspace.

[ Upstream commit 29535f7b ] The current handler of MMC_BLK_CMD_ERR in mmc_blk_issue_rw_rq function may cause new coming request permanent missing when the ongoing request (previoulsy started) complete end. The problem scenario is as follows: (1) Request A is ongoing; (2) Request B arrived, and finally mmc_blk_issue_rw_rq() is called; (3) Request A encounters the MMC_BLK_CMD_ERR error; (4) In the error handling of MMC_BLK_CMD_ERR, suppose mmc_blk_cmd_err() end request A completed and return zero. Continue the error handling, suppose mmc_blk_reset() reset device success; (5) Continue the execution, while loop completed because variable ret is zero now; (6) Finally, mmc_blk_issue_rw_rq() return without processing request B. The process related to the missing request may wait that IO request complete forever, possibly crashing the application or hanging the system. Fix this issue by starting new request when reset success. Signed-off-by:

This is done using iscsit_start_kthreads() -> kthread_run() to start new kthreads from within iscsi_post_login_handler(), and invoking kthread_stop() from existing iscsit_close_connection() code. Also, convert iscsit_logout_post_handler_closesession() code to use cmpxchg when determing when iscsit_cause_connection_reinstatement() needs to sleep waiting for completion. Reported-by:

[ Upstream commit 6224beb1 ] Fengguang Wu's tests triggered a bug in the branch tracer's start up test when CONFIG_DEBUG_PREEMPT set. This was because that config adds some debug logic in the per cpu field, which calls back into the branch tracer. The branch tracer has its own recursive checks, but uses a per cpu variable to implement it. If retrieving the per cpu variable calls back into the branch tracer, you can see how things will break. Instead of using a per cpu variable, use the trace_recursion field of the current task struct. Simply set a bit when entering the branch tracing and clear it when leaving. If the bit is set on entry, just don't do the tracing. There's also the case with lockdep, as the local_irq_save() called before the recursion can also trigger code that can call back into the function. Changing that to a raw_local_irq_save() will protect that as well. This prevents the recursion and the inevitable crash that follows.

[ Upstream commit b4875bbe ] When testing the fix for the trace filter, I could not come up with a scenario where the operand count goes below zero, so I added a WARN_ON_ONCE(cnt < 0) to the logic. But there is legitimate case that it can happen (although the filter would be wrong). # echo '>' > /sys/kernel/debug/events/ext4/ext4_truncate_exit/filter That is, a single operation without any operands will hit the path where the WARN_ON_ONCE() can trigger. Although this is harmless, and the filter is reported as a error. But instead of spitting out a warning to the kernel dmesg, just fail nicely and report it via the proper channels.

[ Upstream commit HEAD ] commit ca4da5dd upstream. __key_link_end is not freeing the associated array edit structure and this leads to a 512 byte memory leak each time an identical existing key is added with add_key(). The reason the add_key() system call returns okay is that key_create_or_update() calls __key_link_begin() before checking to see whether it can update a key directly rather than adding/replacing - which it turns out it can. Thus __key_link() is not called through __key_instantiate_and_link() and __key_link_end() must cancel the edit. CVE-2015-1333 Signed-off-by:

[ Upstream commit 34968106 ] virt_dev->num_cached_rings counts on freed ring and is not updated correctly. In xhci_free_or_cache_endpoint_ring() function, the free ring is added into cache and then num_rings_cache is incremented as below: virt_dev->ring_cache[rings_cached] = virt_dev->eps[ep_index].ring; virt_dev->num_rings_cached++; here, free ring pointer is added to a current index and then index is incremented. So current index always points to empty location in the ring cache. For getting available free ring, current index should be decremented first and then corresponding ring buffer value should be taken from ring cache. But In function xhci_endpoint_init(), the num_rings_cached index is accessed before decrement. virt_dev->eps[ep_index].new_ring = virt_dev->ring_cache[virt_dev->num_rings_cached]; virt_dev->ring_cache[virt_dev->num_rings_cached] = NULL; virt_dev->num_rings_cached--; This is bug in manipulating the index of ring cache. And it should be as below: virt_dev->num_rings_cached--; virt_dev->eps[ep_index].new_ring = virt_dev->ring_cache[virt_dev->num_rings_cached]; virt_dev->ring_cache[virt_dev->num_rings_cached] = NULL; Cc: <stable@vger.kernel.org> Signed-off-by:

[ Upstream commit aebda618 ] This fixes an issue introduced in commit b23c8439 (usb: dwc3: gadget: fix DEPSTARTCFG for non-EP0 EPs) that made sure we would only use DEPSTARTCFG once per SetConfig. The trick is that we should use one DEPSTARTCFG per SetConfig *OR* SetInterface. SetInterface was completely missed from the original patch. This problem became aparent after commit 76e838c9 (usb: dwc3: gadget: return error if command sent to DEPCMD register fails) added checking of the return status of device endpoint commands. 'Set Endpoint Transfer Resource' command was caught failing occasionally. This is because the Transfer Resource Index was not getting reset during a SET_INTERFACE request. Finally, to fix the issue, was we have to do is make sure that our start_config_issued flag gets reset whenever we receive a SetInterface request. To verify the problem (and its fix), all we have to do is run test 9 from testusb with 'testusb -t 9 -s 2048 -a -c 5000'. Tested-by:
