commit 0c32b8ec upstream. Interrupt routine must wake process waiting for given interrupt AFTER updating driver's internal structures and contexts. Doing it in-between is a serious bug. This patch moves all calls to the wake() function to the end of the interrupt processing block to avoid potential and real races, especially on multi-core platforms. This also fixes following issue reported from clock core (clocks were disabled in interrupt after being unprepared from the other place in the driver, the stack trace however points to the different place than s5p_mfc driver because of the race): WARNING: CPU: 1 PID: 18 at drivers/clk/clk.c:544 clk_core_unprepare+0xc8/0x108 Modules linked in: CPU: 1 PID: 18 Comm: kworker/1:0 Not tainted 4.10.0-next-20170223-00070-g04e18bc99ab9-dirty #2154 Hardware name: SAMSUNG EXYNOS (Flattened Device Tree) Workqueue: pm pm_runtime_work [<c010d8b0>] (unwind_backtrace) from [<c010a534>] (show_stack+0x10/0x14) [<c010a534>] (show_stack) from [<c033292c>] (dump_stack+0x74/0x94) [<c033292c>] (dump_stack) from [<c011cef4>] (__warn+0xd4/0x100) [<c011cef4>] (__warn) from [<c011cf40>] (warn_slowpath_null+0x20/0x28) [<c011cf40>] (warn_slowpath_null) from [<c0387a84>] (clk_core_unprepare+0xc8/0x108) [<c0387a84>] (clk_core_unprepare) from [<c0389d84>] (clk_unprepare+0x24/0x2c) [<c0389d84>] (clk_unprepare) from [<c03d4660>] (exynos_sysmmu_suspend+0x48/0x60) [<c03d4660>] (exynos_sysmmu_suspend) from [<c042b9b0>] (pm_generic_runtime_suspend+0x2c/0x38) [<c042b9b0>] (pm_generic_runtime_suspend) from [<c0437580>] (genpd_runtime_suspend+0x94/0x220) [<c0437580>] (genpd_runtime_suspend) from [<c042e240>] (__rpm_callback+0x134/0x208) [<c042e240>] (__rpm_callback) from [<c042e334>] (rpm_callback+0x20/0x80) [<c042e334>] (rpm_callback) from [<c042d3b8>] (rpm_suspend+0xdc/0x458) [<c042d3b8>] (rpm_suspend) from [<c042ea24>] (pm_runtime_work+0x80/0x90) [<c042ea24>] (pm_runtime_work) from [<c01322c4>] (process_one_work+0x120/0x318) [<c01322c4>] (process_one_work) from [<c0132520>] (worker_thread+0x2c/0x4ac) [<c0132520>] (worker_thread) from [<c0137ab0>] (kthread+0xfc/0x134) [<c0137ab0>] (kthread) from [<c0107978>] (ret_from_fork+0x14/0x3c) ---[ end trace 1ead49a7bb83f0d8 ]--- Fixes: af935746 ("[media] MFC: Add MFC 5.1 V4L2 driver") Signed-off-by:

commit 5d9854ea upstream. This change undo the change done by 'commit 3bec2474 ("iio: hid-sensor-trigger: Change get poll value function order to avoid sensor properties losing after resume from S3")' as this breaks some USB/i2c sensor hubs. Instead of relying on HW for restoring poll and hysteresis, driver stores and restores on resume (S3). In this way user space modified settings are not lost for any kind of sensor hub behavior. In this change, whenever user space modifies sampling frequency or hysteresis driver will get the feature value from the hub and store in the per device hid_sensor_common data structure. On resume callback from S3, system will set the feature to sensor hub, if user space ever modified the feature value.

commit 3c50ffef upstream. Commit d8e5f0ec ("usb: musb: Fix hardirq-safe hardirq-unsafe lock order error") caused a regression where musb keeps trying to enable host mode with no cable connected. This seems to be caused by the fact that now phy is enabled earlier, and we are wrongly trying to force USB host mode on an OTG port. The errors we are getting are "trying to suspend as a_idle while active". For ports configured as OTG, we should not need to do anything to try to force USB host mode on it's OTG port. Trying to force host mode in this case just seems to completely confuse the musb state machine. Let's fix the issue by making musb_host_setup() attempt to force the mode only if port_mode is configured for host mode.

commit d325a1de upstream. The dwc3 driver can overwite its previous events if its top-half IRQ handler (TH) gets invoked again before processing the events in the cache. We see this as a hang in the file transfer and the host will attempt to reset the device. TH gets the event count and deasserts the interrupt line by writing DWC3_GEVNTSIZ_INTMASK to DWC3_GEVNTSIZ. If there's a new event coming between reading the event count and interrupt deassertion, dwc3 will lose previous pending events. More generally, we will see 0 event count, which should not affect anything. This shouldn't be possible in the current dwc3 implementation. However, through testing and reading the PCIe trace, the TH occasionally still gets invoked one more time after HW interrupt deassertion. (With PCIe legacy interrupts, TH is called repeatedly as long as the interrupt line is asserted). We suspect that there is a small detection delay in the SW. To avoid this issue, Check DWC3_EVENT_PENDING flag to determine if the events are processed in the bottom-half IRQ handler. If not, return IRQ_HANDLED and don't process new event. Signed-off-by:

commit 6b06cdee upstream. When accessing an encrypted directory without the key, userspace must operate on filenames derived from the ciphertext names, which contain arbitrary bytes. Since we must support filenames as long as NAME_MAX, we can't always just base64-encode the ciphertext, since that may make it too long. Currently, this is solved by presenting long names in an abbreviated form containing any needed filesystem-specific hashes (e.g. to identify a directory block), then the last 16 bytes of ciphertext. This needs to be sufficient to identify the actual name on lookup. However, there is a bug. It seems to have been assumed that due to the use of a CBC (ciphertext block chaining)-based encryption mode, the last 16 bytes (i.e. the AES block size) of ciphertext would depend on the full plaintext, preventing collisions. However, we actually use CBC with ciphertext stealing (CTS), which handles the last two blocks specially, causing them to appear "flipped". Thus, it's actually the second-to-last block which depends on the full plaintext. This caused long filenames that differ only near the end of their plaintexts to, when observed without the key, point to the wrong inode and be undeletable. For example, with ext4: # echo pass | e4crypt add_key -p 16 edir/ # seq -f "edir/abcdefghijklmnopqrstuvwxyz012345%.0f" 100000 | xargs touch # find edir/ -type f | xargs stat -c %i | sort | uniq | wc -l 100000 # sync # echo 3 > /proc/sys/vm/drop_caches # keyctl new_session # find edir/ -type f | xargs stat -c %i | sort | uniq | wc -l 2004 # rm -rf edir/ rm: cannot remove 'edir/_A7nNFi3rhkEQlJ6P,hdzluhODKOeWx5V': Structure needs cleaning ... To fix this, when presenting long encrypted filenames, encode the second-to-last block of ciphertext rather than the last 16 bytes. Although it would be nice to solve this without depending on a specific encryption mode, that would mean doing a cryptographic hash like SHA-256 which would be much less efficient. This way is sufficient for now, and it's still compatible with encryption modes like HEH which are strong pseudorandom permutations. Also, changing the presented names is still allowed at any time because they are only provided to allow applications to do things like delete encrypted directories. They're not designed to be used to persistently identify files --- which would be hard to do anyway, given that they're encrypted after all. For ease of backports, this patch only makes the minimal fix to both ext4 and f2fs. It leaves ubifs as-is, since ubifs doesn't compare the ciphertext block yet. Follow-on patches will clean things up properly and make the filesystems use a shared helper function. Fixes: 5de0b4d0 ("ext4 crypto: simplify and speed up filename encryption") Reported-by:

commit 6332cd32 upstream. If user has no key under an encrypted dir, fscrypt gives digested dentries. Previously, when looking up a dentry, f2fs only checks its hash value with first 4 bytes of the digested dentry, which didn't handle hash collisions fully. This patch enhances to check entire dentry bytes likewise ext4.

commit bb246681 upstream. Commit 557aaa7f ("ft232: support the ASYNC_LOW_LATENCY flag") enables unprivileged users to set the FTDI latency timer, but there was a logic flaw that skipped sending the corresponding USB control message to the device. Specifically, the device latency timer would not be updated until next open, something which was later also inadvertently broken by commit c19db4c9 ("USB: ftdi_sio: set device latency timeout at port probe"). A recent commit c6dce262 ("USB: serial: ftdi_sio: fix extreme low-latency setting") disabled the low-latency mode by default so we now need this fix to allow unprivileged users to again enable it.

commit 3fd37226 upstream. Imagine we have a pid namespace and a task from its parent's pid_ns, which made setns() to the pid namespace. The task is doing fork(), while the pid namespace's child reaper is dying. We have the race between them: Task from parent pid_ns Child reaper copy_process() .. alloc_pid() .. .. zap_pid_ns_processes() .. disable_pid_allocation() .. read_lock(&tasklist_lock) .. iterate over pids in pid_ns .. kill tasks linked to pids .. read_unlock(&tasklist_lock) write_lock_irq(&tasklist_lock); .. attach_pid(p, PIDTYPE_PID); .. .. .. So, just created task p won't receive SIGKILL signal, and the pid namespace will be in contradictory state. Only manual kill will help there, but does the userspace care about this? I suppose, the most users just inject a task into a pid namespace and wait a SIGCHLD from it. The patch fixes the problem. It simply checks for (pid_ns->nr_hashed & PIDNS_HASH_ADDING) in copy_process(). We do it under the tasklist_lock, and can't skip PIDNS_HASH_ADDING as noted by Oleg: "zap_pid_ns_processes() does disable_pid_allocation() and then takes tasklist_lock to kill the whole namespace. Given that copy_process() checks PIDNS_HASH_ADDING under write_lock(tasklist) they can't race; if copy_process() takes this lock first, the new child will be killed, otherwise copy_process() can't miss the change in ->nr_hashed." If allocation is disabled, we just return -ENOMEM like it's made for such cases in alloc_pid(). v2: Do not move disable_pid_allocation(), do not introduce a new variable in copy_process() and simplify the patch as suggested by Oleg Nesterov. Account the problem with double irq enabling found by Eric W. Biederman. Fixes: c876ad76 ("pidns: Stop pid allocation when init dies") Signed-off-by:
