[PATCH RESEND] PCI/AER: Check for NULL aer_info before ratelimiting in pci_print_aer()

by Breno Leitao

Similarly to pci_dev_aer_stats_incr(), pci_print_aer() may be called when dev->aer_info is NULL. Add a NULL check before proceeding to avoid calling aer_ratelimit() with a NULL aer_info pointer, returning 1, which does not rate limit, given this is fatal. This prevents a kernel crash triggered by dereferencing a NULL pointer in aer_ratelimit(), ensuring safer handling of PCI devices that lack AER info. This change aligns pci_print_aer() with pci_dev_aer_stats_incr() which already performs this NULL check.

[PATCH v3 00/11 6.1.y] Backport minmax.h updates from v6.17-rc7

by Eliav Farber

This series backports 13 patches to update minmax.h in the 6.1.y branch, aligning it with v6.17-rc7. The ultimate goal is to synchronize all longterm branches so that they include the full set of minmax.h changes (6.12.y and 6.6.y were already backported by me and are now ligned). The key motivation is to bring in commit d03eba99f5bf ("minmax: allow min()/max()/clamp() if the arguments have the same signedness"), which is missing in older kernels. In mainline, this change enables min()/max()/clamp() to accept mixed argument types, provided both have the same signedness. Without it, backported patches that use these forms may trigger compiler warnings, which escalate to build failures when -Werror is enabled. Changes in v3: - v2 included 13 patches: https://lore.kernel.org/stable/20250929183358.18982-1-farbere@amazon.com/ - First 2 were accepted and are part of 6.1.155. - 3rd caused build in drivers/md/ to fail: In file included from ./include/linux/container_of.h:5, from ./include/linux/list.h:5, from ./include/linux/wait.h:7, from ./include/linux/mempool.h:8, from ./include/linux/bio.h:8, from drivers/md/dm-bio-record.h:10, from drivers/md/dm-integrity.c:9: drivers/md/dm-integrity.c: In function ‘integrity_metadata’: drivers/md/dm-integrity.c:131:105: error: ISO C90 forbids variable length array ‘checksums_onstack’ [-Werror=vla] 131 | #define MAX_TAG_SIZE (JOURNAL_SECTOR_DATA - JOURNAL_MAC_PER_SECTOR - offsetof(struct journal_entry, last_bytes[MAX_SECTORS_PER_BLOCK])) | ^~~~~~~~~~~~~ ./include/linux/build_bug.h:78:56: note: in definition of macro ‘__static_assert’ 78 | #define __static_assert(expr, msg, ...) _Static_assert(expr, msg) | ^~~~ ./include/linux/minmax.h:56:9: note: in expansion of macro ‘static_assert’ 56 | static_assert(__types_ok(x, y, ux, uy), \ | ^~~~~~~~~~~~~ ./include/linux/minmax.h:41:31: note: in expansion of macro ‘__is_noneg_int’ 41 | __is_noneg_int(x) || __is_noneg_int(y)) | ^~~~~~~~~~~~~~ ./include/linux/minmax.h:56:23: note: in expansion of macro ‘__types_ok’ 56 | static_assert(__types_ok(x, y, ux, uy), \ | ^~~~~~~~~~ ./include/linux/minmax.h:61:9: note: in expansion of macro ‘__careful_cmp_once’ 61 | __careful_cmp_once(op, x, y, __UNIQUE_ID(x_), __UNIQUE_ID(y_)) | ^~~~~~~~~~~~~~~~~~ ./include/linux/minmax.h:92:25: note: in expansion of macro ‘__careful_cmp’ 92 | #define max(x, y) __careful_cmp(max, x, y) | ^~~~~~~~~~~~~ drivers/md/dm-integrity.c:1797:40: note: in expansion of macro ‘max’ 1797 | char checksums_onstack[max((size_t)HASH_MAX_DIGESTSIZE, MAX_TAG_SIZE)]; | ^~~ drivers/md/dm-integrity.c:131:89: note: in expansion of macro ‘offsetof’ 131 | #define MAX_TAG_SIZE (JOURNAL_SECTOR_DATA - JOURNAL_MAC_PER_SECTOR - offsetof(struct journal_entry, last_bytes[MAX_SECTORS_PER_BLOCK])) | ^~~~~~~~ drivers/md/dm-integrity.c:1797:73: note: in expansion of macro ‘MAX_TAG_SIZE’ 1797 | char checksums_onstack[max((size_t)HASH_MAX_DIGESTSIZE, MAX_TAG_SIZE)]; | ^~~~~~~~~~~~ - The build was fixed in the second patch of this series.

The constraint will be set against the period time rather than the buffer time to make sure that application will not face with xruns when the DMA bursts to refill the host buffer. The minimal period size will be also used by Pipewire in case of SOF cards to set the headroom to a length which will avoid the cases when the hw_ptr jumps over the appl_ptr because of a burst.

(Line numbers based on commit da274362a7bd9 ("Linux 6.12.49") This started happening after commit f4da7afe07523f ("kexec_file: increase maximum file size to 4G") that landed in v6.0, which increased the file size for kexec. This is not happening upstream (v6.16+), given that `block` type was upgraded from "int" to "size_t" in commit 74a43a2cf5e8 ("crypto: lib/sha256 - Move partial block handling out") Upgrade the block type similar to the commit above, avoiding hitting the overflow. This patch is only suitable for the stable tree, and before 6.16, which got commit 74a43a2cf5e8 ("crypto: lib/sha256 - Move partial block handling out"). This is not required before f4da7afe07523f ("kexec_file: increase maximum file size to 4G"). In other words, this fix is required between versions v6.0 and v6.16.

[PATCH v2 01/15] serial: sc16is7xx: remove useless enable of enhanced features

by Hugo Villeneuve

From: Hugo Villeneuve <hvilleneuve(a)dimonoff.com> Commit 43c51bb573aa ("sc16is7xx: make sure device is in suspend once probed") permanently enabled access to the enhanced features in sc16is7xx_probe(), and it is never disabled after that. Therefore, remove useless re-enable of enhanced features in sc16is7xx_set_baud().

[PATCH 11/14] iommu/omap: fix device leaks on probe_device()
