The support for the compat ioctl did not actually do what it was supposed to do because of a typo, instead it broke native support for CDROM_LAST_WRITTEN and CDROM_SEND_PACKET on all architectures with CONFIG_COMPAT enabled. Fixes: 1b114b08 ("pktcdvd: add compat_ioctl handler") Signed-off-by:

Under heavy loads where the kyber I/O scheduler hits the token limits for its scheduling domains, kyber can become stuck. When active requests complete, kyber may not be woken up leaving the I/O requests in kyber stuck. This stuck state is due to a race condition with kyber and the sbitmap functions it uses to run a callback when enough requests have completed. The running of a sbt_wait callback can race with the attempt to insert the sbt_wait. Since sbitmap_del_wait_queue removes the sbt_wait from the list first then sets the sbq field to NULL, kyber can see the item as not on a list but the call to sbitmap_add_wait_queue will see sbq as non-NULL. This results in the sbt_wait being inserted onto the wait list but ws_active doesn't get incremented. So the sbitmap queue does not know there is a waiter on a wait list. Since sbitmap doesn't think there is a waiter, kyber may never be informed that there are domain tokens available and the I/O never advances. With the sbt_wait on a wait list, kyber believes it has an active waiter so cannot insert a new waiter when reaching the domain's full state. This race can be fixed by only adding the sbt_wait to the queue if the sbq field is NULL. If sbq is not NULL, there is already an action active which will trigger the re-running of kyber. Let it run and add the sbt_wait to the wait list if still needing to wait. Reviewed-by:

If for whatever reason the dasd_eckd_check_characteristics() function exits after at least some paths have their configuration data allocated those data is never freed again. In the error case the device->private pointer is set to NULL and dasd_eckd_uncheck_device() will exit without freeing the path data because of this NULL pointer. Fix by calling dasd_eckd_clear_conf_data() for error cases. Also use dasd_eckd_clear_conf_data() in dasd_eckd_uncheck_device() to avoid code duplication. Reported-by:

The max data count (mdc) is an unsigned 16-bit integer value as per AR documentation and is received via ccw_device_get_mdc() for a specific path mask from the CIO layer. The function itself also always returns a positive mdc value or 0 in case mdc isn't supported or couldn't be determined. Though, the comment for this function describes a negative return value to indicate failures. As a result, the DASD device driver interprets the return value of ccw_device_get_mdc() incorrectly. The error case is essentially a dead code path. To fix this behaviour, check explicitly for a return value of 0 and change the comment for ccw_device_get_mdc() accordingly. This fix merely enables the error code path in the DASD functions get_fcx_max_data() and verify_fcx_max_data(). The actual functionality stays the same and is still correct. Reviewed-by:

This fixes a regression added with: commit e9e006f5 Author: Mike Christie <mchristi@redhat.com> Date: Sun Aug 4 14:10:06 2019 -0500 nbd: fix max number of supported devs where we can deadlock during device shutdown. The problem occurs if the recv_work's nbd_config_put occurs after nbd_start_device_ioctl has returned and the userspace app has droppped its reference via closing the device and running nbd_release. The recv_work nbd_config_put call would then drop the refcount to zero and try to destroy the config which would try to do destroy_workqueue from the recv work. This patch just has nbd_start_device_ioctl do a flush_workqueue when it wakes so we know after the ioctl returns running works have exited. This also fixes a possible race where we could try to reuse the device while old recv_works are still running.

When over-budget IOs are force-issued through root cgroup, iocg_kick_delay() adjusts the async delay accordingly but doesn't actually schedule async throttle for the issuing task. This bug is pretty well masked because sooner or later the offending threads are gonna get directly throttled on regular IOs or have async delay scheduled by mem_cgroup_throttle_swaprate(). However, it can affect control quality on filesystem metadata heavy operations. Let's fix it by invoking blkcg_schedule_throttle() when iocg_kick_delay() says async delay is needed. Signed-off-by:

The "trivial conversion" in commit cccaa5e3 ("init: use do_mount() instead of ksys_mount()") was totally broken, since it didn't handle the case of a NULL mount data pointer. And while I had "tested" it (and presumably Dominik had too) that bug was hidden by me having options.

Pull ksys_mount() and ksys_dup() removal from Dominik Brodowski: "This small series replaces all in-kernel calls to the userspace-focused ksys_mount() and ksys_dup() with calls to kernel-centric functions: For each replacement of ksys_mount() with do_mount(), one needs to verify that the first and third parameter (char *dev_name, char *type) are strings allocated in kernelspace and that the fifth parameter (void *data) is either NULL or refers to a full page (only occurence in init/do_mounts.c::do_mount_root()). The second and fourth parameters (char *dir_name, unsigned long flags) are passed by ksys_mount() to do_mount() unchanged, and therefore do not require particular care. Moreover, instead of pretending to be userspace, the opening of /dev/console as stdin/stdout/stderr can be implemented using in-kernel functions as well. Thereby, ksys_dup() can be removed for good" [ This doesn't get rid of the special "kernel init runs with KERNEL_DS" case, but it at least removes _some_ of the users of "treat kernel pointers as user pointers for our magical init sequence". One day we'll hopefully be rid of it all, and can initialize our init_thread addr_limit to USER_DS. - Linus ] * 'remove-ksys-mount-dup' of git://git.kernel.org/pub/scm/linux/kernel/git/brodo/linux: fs: remove ksys_dup() init: unify opening /dev/console as stdin/stdout/stderr init: use do_mount() instead of ksys_mount() initrd: use do_mount() instead of ksys_mount() devtmpfs: use do_mount() instead of ksys_mount()
