[PATCH 6.12.y 1/3] drm/sched: Optimise drm_sched_entity_push_job

by Jules Maselbas

From: Tvrtko Ursulin <tvrtko.ursulin(a)igalia.com> commit d42a254633c773921884a19e8a1a0f53a31150c3 upstream. In FIFO mode (which is the default), both drm_sched_entity_push_job() and drm_sched_rq_update_fifo(), where the latter calls the former, are currently taking and releasing the same entity->rq_lock. We can avoid that design inelegance, and also have a miniscule efficiency improvement on the submit from idle path, by introducing a new drm_sched_rq_update_fifo_locked() helper and pulling up the lock taking to its callers. v2: * Remove drm_sched_rq_update_fifo() altogether.

[PATCH v2] comedi: fix divide-by-zero in comedi_buf_munge()

by Deepanshu Kartikey

The comedi_buf_munge() function performs a modulo operation `async->munge_chan %= async->cmd.chanlist_len` without first checking if chanlist_len is zero. If a user program submits a command with chanlist_len set to zero, this causes a divide-by-zero error when the device processes data in the interrupt handler path. Add a check for zero chanlist_len at the beginning of the function, similar to the existing checks for !map and CMDF_RAWDATA flag. When chanlist_len is zero, update munge_count and return early, indicating the data was handled without munging. This prevents potential kernel panics from malformed user commands.

[PATCH 1/1] mm/thp: fix MTE tag mismatch when replacing zero-filled subpages

by Lance Yang

From: Lance Yang <lance.yang(a)linux.dev> When both THP and MTE are enabled, splitting a THP and replacing its zero-filled subpages with the shared zeropage can cause MTE tag mismatch faults in userspace. Remapping zero-filled subpages to the shared zeropage is unsafe, as the zeropage has a fixed tag of zero, which may not match the tag expected by the userspace pointer. KSM already avoids this problem by using memcmp_pages(), which on arm64 intentionally reports MTE-tagged pages as non-identical to prevent unsafe merging. As suggested by David[1], this patch adopts the same pattern, replacing the memchr_inv() byte-level check with a call to pages_identical(). This leverages existing architecture-specific logic to determine if a page is truly identical to the shared zeropage. Having both the THP shrinker and KSM rely on pages_identical() makes the design more future-proof, IMO. Instead of handling quirks in generic code, we just let the architecture decide what makes two pages identical.

[PATCH] comedi: fix divide-by-zero in comedi_buf_munge()

by Deepanshu Kartikey

The comedi_buf_munge() function performs a modulo operation `async->munge_chan %= async->cmd.chanlist_len` without first checking if chanlist_len is zero. If a user program submits a command with chanlist_len set to zero, this causes a divide-by-zero error when the device processes data in the interrupt handler path. Add a check for zero chanlist_len at the beginning of the function, similar to the existing checks for !map and CMDF_RAWDATA flag. When chanlist_len is zero, update munge_count and return early, indicating the data was handled without munging. This prevents potential kernel panics from malformed user commands.
