drm/amdkfd: Fix the warning of array-index-out-of-bounds

commit c0cc999f3c32e65a7c88fb323893ddf897b24488 upstream. For some GPUs with more CUs, the original sibling_map[32] in struct crat_subtype_cache is not enough to save the cache information when create the VCRAT table, so skip filling the struct crat_subtype_cache info instead fill struct kfd_cache_properties directly to fix this problem.

dm crypt: avoid accessing uninitialized tasklet

2023-03-30T10:49:30+00:00

commit d9a02e016aaf5a57fb44e9a5e6da8ccd3b9e2e70 upstream. When neither "no_read_workqueue" nor "no_write_workqueue" are enabled, tasklet_trylock() in crypt_dec_pending() may still return false due to an uninitialized state, and dm-crypt will unnecessarily do io completion in io_queue workqueue instead of current context. Fix this by adding an 'in_tasklet' flag to dm_crypt_io struct and initialize it to false in crypt_io_init(). Set this flag to true in kcryptd_queue_crypt() before calling tasklet_schedule(). If set crypt_dec_pending() will punt io completion to a workqueue. This also nicely avoids the tasklet_trylock/unlock hack when tasklets aren't in use.

dm crypt: add cond_resched() to dmcrypt_write()

2023-03-30T10:49:30+00:00

commit fb294b1c0ba982144ca467a75e7d01ff26304e2b upstream. The loop in dmcrypt_write may be running for unbounded amount of time, thus we need cond_resched() in it.

dm stats: check for and propagate alloc_percpu failure

2023-03-30T10:49:30+00:00

commit d3aa3e060c4a80827eb801fc448debc9daa7c46b upstream. Check alloc_precpu()'s return value and return an error from dm_stats_init() if it fails. Update alloc_dev() to fail if dm_stats_init() does. Otherwise, a NULL pointer dereference will occur in dm_stats_cleanup() even if dm-stats isn't being actively used.

commit 92fbb6d1296f81f41f65effd7f5f8c0f74943d15 upstream. The data->block[0] variable comes from user and is a number between 0-255. Without proper check, the variable may be very large to cause an out-of-bounds when performing memcpy in slimpro_i2c_blkwr. Fix this bug by checking the value of writelen.

bus: imx-weim: fix branch condition evaluates to a garbage value

commit 1adab2922c58e7ff4fa9f0b43695079402cce876 upstream. If bus type is other than imx50_weim_devtype and have no child devices, variable 'ret' in function weim_parse_dt() will not be initialized, but will be used as branch condition and return value. Fix this by initializing 'ret' with 0. This was discovered with help of clang-analyzer, but the situation is quite possible in real life.

soc: qcom: llcc: Fix slice configuration values for SC8280XP

2023-03-30T10:49:29+00:00

commit 77bf4b3ed42e31d29b255fcd6530fb7a1e217e89 upstream. The slice IDs for CVPFW, CPUSS1 and CPUWHT currently overflow the 32bit LLCC config registers, which means it is writing beyond the upper limit of the ATTR0_CFGn and ATTR1_CFGn range of registers. But the most obvious impact is the fact that the mentioned slices do not get configured at all, which will result in reduced performance. Fix that by using the slice ID values taken from the latest LLCC SC table.
