2023-10-31dm crypt: account large pages in cc->n_allocated_pagesMikulas Patocka1-3/+12
The commit 5054e778fcd9c ("dm crypt: allocate compound pages if possible") changed dm-crypt to use compound pages to improve performance. Unfortunately, there was an oversight: the allocation of compound pages was not accounted at all. Normal pages are accounted in a percpu counter cc->n_allocated_pages and dm-crypt is limited to allocate at most 2% of memory. Because compound pages were not accounted at all, dm-crypt could allocate memory over the 2% limit. Fix this by adding the accounting of compound pages, so that memory consumption of dm-crypt is properly limited.

2023-10-31ACPI: thermal: Fix acpi_thermal_unregister_thermal_zone() cleanupDan Carpenter1-2/+2
The acpi_thermal_unregister_thermal_zone() is paired with acpi_thermal_register_thermal_zone() so it should mirror it. It should clean up all the resources that the register function allocated and leave the stuff that was allocated elsewhere. Unfortunately, it doesn't call thermal_zone_device_disable(). Also it calls kfree(tz->trip_table) when it shouldn't. That was allocated in acpi_thermal_add(). Putting the kfree() here leads to a double free in the acpi_thermal_add() clean up function. Likewise, the acpi_thermal_remove() should mirror acpi_thermal_add() so it should have an explicit kfree(tz->trip_table) as well.

2023-10-31dm error: Add support for zoned block devicesDamien Le Moal2-4/+125
dm-error is used in several test cases in the xfstests test suite to check the handling of IO errors in file systems. However, with several file systems getting native support for zoned block devices (e.g. btrfs and f2fs), dm-error's lack of zoned block device support creates problems as the file system attempts executing zone commands (e.g. a zone append operation) against a dm-error non-zoned block device, which causes various issues in the block layer (e.g. WARN_ON triggers). This commit adds supports for zoned block devices to dm-error, allowing a DM device table containing an error target to be exposed as a zoned block device (if all targets have a compatible zoned model support and mapping). This is done as follows: 1) Allow passing 2 arguments to an error target, similar to dm-linear: a backing device and a start sector. These arguments are optional and dm-error retains its characteristics if the arguments are not specified. 2) Implement the iterate_devices method so that dm-core can normally check the zone support and restrictions (e.g. zone alignment of the targets). When the backing device arguments are not specified, the iterate_devices method never calls the fn() argument. When no backing device is specified, as before, we assume that the DM device is not zoned. When the backing device arguments are specified, the zoned model of the DM device will depend on the backing device type: - If the backing device is zoned and its model and mapping is compatible with other targets of the device, the resulting device will be zoned, with the dm-error mapped portion always returning errors (similar to the default non-zoned case). - If the backing device is not zoned, then the DM device will not be either. This zone support for dm-error requires the definition of a functional report_zones operation so that dm_revalidate_zones() can operate correctly and resources for emulating zone append operations initialized. This is necessary for cases where dm-error is used to partially map a device and have an overall correct handling of zone append. This means that dm-error does not fail report zones operations. Two changes that are not obvious are included to avoid issues: 1) dm_table_supports_zoned_model() is changed to directly check if the backing device of a wildcard target (= dm-error target) is zoned. Otherwise, we wouldn't be able to catch the invalid setup of dm-error without a backing device (non zoned case) being combined with zoned targets. 2) dm_table_supports_dax() is modified to return false if the wildcard target is found. Otherwise, when dm-error is set without a backing device, we end up with a NULL pointer dereference in set_dax_synchronous (dax_dev is NULL). This is consistent with the current behavior because dm_table_supports_dax() always returned false for targets that do not define the iterate_devices method.

2023-10-31dm delay: for short delays, use kthread instead of timers and wqChristian Loehle1-15/+88
DM delay's current design of using timers and wq to realize the delays is insufficient for delays below ~50ms. This commit enhances the design to use a kthread to flush the expired delays, trading some CPU time (in some cases) for better delay accuracy and delays closer to what the user requested for smaller delays. The new design is chosen as long as all the delays are below 50ms. Since bios can't be completed in interrupt context using a kthread is probably the most reasonable way to approach this. Testing with echo "0 2097152 zero" | dmsetup create dm-zeros for i in $(seq 0 20); do echo "0 2097152 delay /dev/mapper/dm-zeros 0 $i" | dmsetup create dm-delay-${i}ms; done Some performance numbers for comparison, on beaglebone black (single core) CONFIG_HZ_1000=y: fio --name=1msread --rw=randread --bs=4k --runtime=60 --time_based \ --filename=/dev/mapper/dm-delay-1ms Theoretical maximum: 1000 IOPS Previous: 250 IOPS Kthread: 500 IOPS fio --name=10msread --rw=randread --bs=4k --runtime=60 --time_based \ --filename=/dev/mapper/dm-delay-10ms Theoretical maximum: 100 IOPS Previous: 45 IOPS Kthread: 50 IOPS fio --name=1mswrite --rw=randwrite --direct=1 --bs=4k --runtime=60 \ --time_based --filename=/dev/mapper/dm-delay-1ms Theoretical maximum: 1000 IOPS Previous: 498 IOPS Kthread: 1000 IOPS fio --name=10mswrite --rw=randwrite --direct=1 --bs=4k --runtime=60 \ --time_based --filename=/dev/mapper/dm-delay-10ms Theoretical maximum: 100 IOPS Previous: 90 IOPS Kthread: 100 IOPS (This one is just to prove the new design isn't impacting throughput, not really about delays): fio --name=10mswriteasync --rw=randwrite --direct=1 --bs=4k \ --runtime=60 --time_based --filename=/dev/mapper/dm-delay-10ms \ --numjobs=32 --iodepth=64 --ioengine=libaio --group_reporting Previous: 13.3k IOPS Kthread: 13.3k IOPS Signed-off-by: Christian Loehle <[email protected]> [Harshit: kthread_create error handling fix in delay_ctr] Signed-off-by: Harshit Mogalapalli <[email protected]> Signed-off-by: Mike Snitzer <[email protected]>
2023-10-31IB/mlx5: Fix init stage error handling to avoid double free of same QP and UAFGeorge Kennedy1-3/+1
In the unlikely event that workqueue allocation fails and returns NULL in mlx5_mkey_cache_init(), delete the call to mlx5r_umr_resource_cleanup() (which frees the QP) in mlx5_ib_stage_post_ib_reg_umr_init(). This will avoid attempted double free of the same QP when __mlx5_ib_add() does its cleanup.

2023-10-31RDMA/mlx5: Fix mkey cache WQ flushMoshe Shemesh1-0/+2
The cited patch tries to ensure no pending works on the mkey cache workqueue by disabling adding new works and call flush_workqueue(). But this workqueue also has delayed works which might still be pending the delay time to be queued. Add cancel_delayed_work() for the delayed works which waits to be queued and then the flush_workqueue() will flush all works which are already queued and running.

This commit adds the initial code needed to boot the GSP-RM firmware provided by NVIDIA, bringing with it the beginnings of Ada support. Until it's had more testing and time to bake, support is disabled by default (except on Ada). GSP-RM usage can be enabled by passing the "config=NvGspRm=1" module option.
