2026-07-17dm vdo: don't read repair field in loop conditionMatthew Sakai
Respell the vio launch loop to use the existing vio_count value. The repair completion is not guaranteed to persist after all of the metadata_vios are launched. This can not currently cause problems due to the way vio callbacks are handled, but it is technically not safe to access those fields.

2026-07-17dm-pcache: only hand out initialized cache segmentsBryam Vargas
get_cache_segment() scans the segment map up to cache->n_segs, the physical device segment count, but cache_segs_init() only initializes the first cache_info->n_segs segments. A crafted image with cache_info->n_segs smaller than the device count leaves the remaining pcache_cache_segment structs zeroed (segment.data == NULL), and the allocator can hand one to cache_kset_close(), which writes through the returned segment's data pointer with no NULL check. Bound the allocator's search to cache_info->n_segs so only initialized segments are ever returned. A conforming cache sets n_segs equal to the device segment count, so this rejects nothing legitimate.

2026-07-17dm-pcache: validate the persisted dirty_tail chain at loadBryam Vargas
The writeback worker follows the persisted dirty_tail chain, which is decoded from the cache device independently of the key_tail chain that cache_replay() walks and bounds. A crafted image, whose on-media fields are authenticated only by a crc32c with a fixed seed, can aim dirty_tail at a chain of last ksets that never terminates, so cache_writeback_fn() re-arms itself with no delay forever. Walk the dirty_tail chain once at load with the same hop cap cache_replay() uses and fail the table load with -EIO if it does not reach an end within n_segs hops.

2026-07-17dm-pcache: validate on-media seg_num against the cache device sizeBryam Vargas
seg_num is read from the crc32c-only superblock, so whoever supplies the cache device on a table load (CAP_SYS_ADMIN) controls it. It sizes cache->segments[] and is the value every later on-media segment id is bounded against, yet it is never checked against the device. Because cache_dev->mapping is the direct map of the pmem, CACHE_DEV_SEGMENT() for a segment id past the device resolves to ordinary kernel memory beyond the mapping; a new-cache init reaching such an id has cache_seg_init() -> cache_dev_zero_range() memset() 12 KiB over that memory -- an out-of-bounds write into the kernel heap at table load. A zero seg_num makes the segment allocations ZERO_SIZE_PTR. Reject a seg_num that is zero, larger than the device can hold, or larger than PCACHE_CACHE_SEGS_MAX before it is used.

The tail-kset read in cache_replay(), the writeback worker and the GC worker bounds its length by PCACHE_SEG_SIZE - seg_off, the raw segment size rather than the data region. A tail near the segment end reads past the segment data into the following control area. Clamp the read to cache_seg_remain(), the data region.

cache_key_decode() takes a key's logical off from the cache device and later indexes req_key_tree->subtrees[] by it in get_subtree(). An off past the device forms a subtree pointer outside the array, which rb_insert() writes through during replay.

2026-07-17dm-pcache: detect a cycle in the last-kset chain during replayBryam Vargas
cache_replay() follows the on-media last-kset chain by next_cache_seg_id with no cond_resched(). A forged chain that points back into a segment it has already visited makes the replay loop follow it forever. Cap the last-kset hops at cache->n_segs; a valid chain visits each segment at most once.

2026-07-17dm-pcache: reject a kset that overruns its segmentBryam Vargas
cache_replay(), the writeback worker and the GC worker read a kset of get_kset_onmedia_size() bytes and advance the position by it. A forged key_num makes that size exceed the segment's remaining space, so the advance walks past the segment and trips the cache_pos_advance() BUG_ON.

2026-07-17dm-pcache: validate kset key_num and intra-segment boundsBryam Vargas
Two more fields decoded from the cache device go unbounded. The kset key_num drives cache_kset_crc() and the replay loop in cache_replay(), the writeback worker and the GC worker, but only the magic and a fixed-seed CRC are checked first, so a non-last kset whose key_num exceeds the PCACHE_KSET_KEYS_MAX buffer reads past its end before the CRC compare. A key's intra-segment offset and length in cache_key_decode() are taken verbatim, so a key running past its segment is replayed into the cache tree and the data CRC check and every later read hit then copy adjacent persistent memory into the caller's bio -- an out-of-bounds read that leaks to user space. Both fields are controlled by whoever supplies the cache device (CAP_SYS_ADMIN); the CRC seed is public. Add kset_onmedia_valid() to bound key_num before any kset read, and reject a key whose offset plus length, computed in 64 bits, exceeds the segment data_size. Valid metadata is unaffected.

2026-07-17dm-pcache: validate geometry fields from on-disk cache_infoBryam Vargas
cache_segs_init() iterates cache_info->n_segs times indexing cache->segments[], which is sized to the cache device geometry, and get_seg_id() takes each segment id from the on-media cache_info and the per-segment next_seg link. Both come from cache device metadata that is only CRC-protected with a fixed public seed, so whoever supplies the cache device on a table load (CAP_SYS_ADMIN) controls them: an oversized n_segs or an out-of-range id drives an out-of-bounds access of cache->segments[] and a wild CACHE_DEV_SEGMENT() pointer into the device mapping -- an out-of-bounds read and write from on-disk data. Reject an n_segs that exceeds the device segment count and a segment id that is out of range before either is used. Valid metadata is unaffected.

2026-07-17dm-pcache: validate seg_id fields from persistent memoryBryam Vargas
cache_pos_decode(), cache_key_decode() and the last-kset branches of cache_replay(), the writeback worker and the GC worker take a cache segment id from the cache device metadata and index cache->segments[] with it without checking it against cache->n_segs. That metadata is only CRC-protected with a fixed public seed, so whoever supplies the cache device on a table load (CAP_SYS_ADMIN) controls the id; an out-of-range value forms a wild pcache_cache_segment pointer that is dereferenced and written through -- an out-of-bounds read and write driven by on-disk data. Add cache_seg_id_valid() and reject an out-of-range id at each decode site, failing the operation with -EIO instead of indexing past the array. Bound the id against the initialized-segment count (cache_info.n_segs) rather than the physical device total. A forged cache_info.n_segs below seg_num otherwise leaves segments[cache_info.n_segs..seg_num) as zeroed structs whose data pointer is NULL, so a forged id in that window would still be dereferenced. A later patch guarantees cache_info.n_segs <= seg_num, and a driver-created cache sets the two equal, so valid images are unaffected.

2026-07-17PCI: imx6: Keep i.MX6 Root Port MSI/MSI-X Capabilities with iMSI-RX to work ↵Soeren Moch
around hardware bug On some NXP chipsets, disabling Root Port MSI/MSI-X Capabilities blocks MSIs originating from Endpoints from reaching the iMSI-RX controller. To address this hardware bug, commit 3a4e8302e72f ("PCI: imx6: Keep Root Port MSI capability with iMSI-RX to work around hardware bug") preserves Root Port MSI and MSI-X Capabilities on i.MX7D, i.MX8MM, and i.MX8MQ when iMSI-RX is in use. The same applies to i.MX6Q, i.MX6QP, and i.MX6SX, so preserve Root Port MSI/MSI-X Capabilities there as well. Note that preserving these Capabilities means Root Port-originated MSIs such as AER and PME won't be received due to separate hardware limitations. Users may need to use workarounds such as passing the 'pcie_pme=nomsi' command-line parameter.

2026-07-17Input: snvs_pwrkey - add press event reporting to avoid event loss during ↵Joy Zou
suspend The driver implements debounce protection using a timer-based mechanism: when a key interrupt occurs, a timer is scheduled to verify the key state after DEBOUNCE_TIME before reporting the event. This works well during normal operation. However, key press events can be lost during system resume on platforms like i.MX8MQ-EVK because: 1. During the no_irq resume phase, PCIe driver restoration can take up to 200ms with IRQs disabled. 2. The power key interrupt remains pending during the no_irq phase. 3. If the key is released before IRQs are re-enabled, the timer eventually runs but sees the key as released and skips reporting the event. To prevent event loss during system suspend, set a pending_press flag in the interrupt handler and report the press event from the timer callback when the flag is set. This avoids out-of-order event delivery and keeps the existing timer-based debounce mechanism for normal operation.

2026-07-17drm/ttm/pool: back up at native page orderMatthew Brost
ttm_pool_split_for_swap() unconditionally splits high-order pool pages into order-0 pages before backup, so every compound the shrinker touches is shattered even when the rest of the system would prefer it stay intact. Under sustained kswapd pressure this fragments memory enough to drive other parts of MM into recovery loops. Back up each compound at its native order instead. In ttm_pool_backup(), hand the full compound to the new ttm_backup_backup_folio(), which backs up subpages to a contiguous range of shmem indices and returns the base handle plus the number of subpages actually backed up (@nr_backed). On full success, free the compound once at its native order -- no split_page(), no per-4K refcount juggling. A per-folio backup can't be made fully atomic under memory pressure: ttm_backup_backup_folio() must allocate shmem folios before source subpages can be released, so under true OOM any subpage may fail while the rest of the compound is still live. Two mechanisms handle this without regressing reclaim behaviour: - alloc_gfp gets __GFP_NOMEMALLOC whenever order > 0 (cleared again for order-0), so a high-order backup fails fast with -ENOMEM instead of draining kernel reserves, leaving them for other allocations under the same pressure. - If ttm_backup_backup_folio() still returns a short @nr_backed with a valid handle for the successfully-backed prefix, split the source compound with ttm_pool_split_for_swap(), free the prefix as order-0 pages (already safely in shmem), and retry the remaining subpages at order 0, where __GFP_NOMEMALLOC is cleared and reserves may be used as a last resort. This preserves the original split-on-OOM fallback while keeping the common case fragmentation-free, and preserves the "partial backup is allowed" contract (shrunken is incremented per subpage backed up). The restore-side leftover-page split in ttm_pool_restore_commit() is left as-is: it's unreachable in practice and not worth complicating the restore state machine to avoid. Testing: the existing backup_fault_inject point only truncated tt->num_pages, which never exercised the reactive split path above since it never left a compound partially backed up. Wire fault injection into ttm_backup_backup_folio() itself: past the first subpage of a compound, synthesize a -ENOMEM in place of shmem_read_folio_gfp() when should_fail() trips, producing the same short @nr_pages_backed a real failure would and forcing ttm_pool_backup() through the split-and-retry path. The fault_attr stays private to ttm_pool.c; ttm_backup.c reaches it through ttm_backup_fault_inject_folio(), declared in ttm_pool_internal.h. While converting the writeback branch to operate on the whole folio, the unlock condition after shmem_writeout() also changed from `if (ret)` to `if (ret == AOP_WRITEPAGE_ACTIVATE)`, matching the actual contract: shmem_writeout()/swap_writeout() only leave the folio locked when returning AOP_WRITEPAGE_ACTIVATE; any other return (including a hard error from arch_prepare_to_swap()) means the folio was already unlocked internally. The old `if (ret)` check would have double- unlocked in that hard-error case.

2026-07-17mtd: part: reject MTDPART_OFS_RETAIN in mtd_add_partition()zhouminqiang
mtd_add_partition() does not reject the special offset value MTDPART_OFS_RETAIN (-3), which leads to a WARN_ON in add_mtd_device() when called through the BLKPG ioctl on NAND devices. The RETAIN value depends on cur_offset being the end of the previous partition, but in the dynamic partition path cur_offset equals the offset argument itself, causing undefined behavior. Commit 5daa7b21496a ("mtd: prepare partition add and del functions for ioctl requests") introduced mtd_add_partition() and correctly rejected MTDPART_OFS_APPEND (-1) and MTDPART_OFS_NXTBLK (-2), since those special offsets rely on cur_offset tracking the previous partition's end. However, commit 1a31368bf92e ("mtd: add a flags for partitions which should just leave smth. after them") later added MTDPART_OFS_RETAIN (-3) for the static partition table path without updating mtd_add_partition() to also reject this value. With offset=-3 passed via BLKPG, the RETAIN size calculation in allocate_partition() underflows (parent_size - 0xFFFFFFFFFFFFFFFD = parent_size + 3). If the underflow result does not appear to leave enough space, allocate_partition() jumps to out_register via goto, skipping erasesize initialization. This results in erasesize=0, which triggers: WARN_ON((!mtd->erasesize || !master->_erase) && !(mtd->flags & MTD_NO_ERASE)) in add_mtd_device(). If the underflow result appears to leave enough space, a bogus partition size is calculated, but the "out of reach" sanity check catches the invalid offset and creates a disabled empty partition (offset=0, size=0) instead of returning an error. Fix this by adding MTDPART_OFS_RETAIN to the rejection list in mtd_add_partition(), consistent with the existing handling of APPEND and NXTBLK.

2026-07-17mtd: mpc5121_nfc: use platform for irq and ioremapRosen Penev
Replace the open-coded of_address_to_resource() plus devm_request_mem_region() and devm_ioremap() sequence with a single devm_platform_ioremap_resource() call, which folds the resource lookup, region reservation and mapping into one step and returns an ERR_PTR on failure, checked with IS_ERR() and propagated via PTR_ERR(). Switch IRQ acquisition from irq_of_parse_and_map() to platform_get_irq(), which only retrieves the interrupt the OF/platform core has already set up rather than transferring mapping ownership to the driver. Drop the now unneeded of_irq.h include. This is behaviorally equivalent: the driver already reserved the region with devm_request_mem_region(), so the non-overlapping reg requirement of devm_platform_ioremap_resource() was already satisfied. Drop the now-unused regs_paddr / regs_size locals, which previously only fed the open-coded request/ioremap calls. Keep the linux/of_address.h include, as of_iomap() is still used elsewhere in the driver. Built for PowerPC (mpc512x_defconfig + CONFIG_MTD_NAND_MPC5121_NFC) with LLVM=1; drivers/mtd/nand/raw/mpc5121_nfc.o compiles cleanly.

2026-07-17mtd: mtdoops: free page bitmap when the backing MTD is removedXu Rao
mtdoops_notify_add() allocates oops_page_used when the configured MTD device is registered. mtdoops_notify_remove() detaches from that device but leaves the bitmap allocated. If the same MTD device is later registered again, the add path allocates a new bitmap and overwrites the old pointer, leaking one vmalloc allocation per remove/add cycle. This is only visible when the backing MTD device can disappear and be registered again while mtdoops remains loaded, so the usual static MTD case does not expose it. Free the bitmap after unregistering the dumper and flushing the pending workers, then clear the pointer and page count before a later attach can allocate fresh state. Clearing the pointer also keeps the module exit path from freeing the same bitmap a second time after a remove event.

2026-07-17mtd: mtdswap: Avoid freeing registered blktrans device twiceRuoyu Wang
In mtdswap_add_mtd(), debugfs setup failure after successful blktrans registration can free mbd_dev twice. add_mtd_blktrans_dev() initializes the blktrans device reference and publishes the disk. Once that succeeds, del_mtd_blktrans_dev() tears the disk down and drops the blktrans reference; when that reference reaches zero, blktrans_dev_release() frees the mtd_blktrans_dev. The debugfs failure path called del_mtd_blktrans_dev(mbd_dev), then fell through the common cleanup label and called kfree(mbd_dev) again. Clear the local pointer after deregistration so the common cleanup can still release the mtdswap state without freeing the blktrans object twice.

At that point there has not been a successful pm_runtime_resume_and_get() call to balance, so the runtime PM usage count can underflow.

With sizeof(struct of_device_id[3]) ≥ 588 having omap_nand_ids[] twice just to do two string comparisons is quite some bloat.

This allows to drop <linux/mod_devicetable.h> from include/linux/platform_data/mtd-nand-omap2.h (which is my original motivation for this change).

2026-07-17drm/i915/cdclk: Deal with 2 PPC hscale issues when calculating min CDCLKVille Syrjälä
Double the fractional part of the horizontal scale factor for the purposes of min_cdck calculation. This bumps the min CDCLK sufficiently to overcome some kind of 2 PPC granularity issue. Without this CDCLK may end up being too low and we get underruns with certain horizontal downscale factors. The current Bspec formula calls for doubling only the fractional part below 0.5, and rounding it down to a unit fraction. But that formula does not result in a sufficient CDCLK bump in a lot of cases. Empirical evidence supports doubling the entire fractional part, so let's just do that while we wait for further analysis from the hardware team. Also note that the position of the scaler output window also seems to matter. If the output is near the left edge of the screen then lower CDCLK is sufficient, but moving the output window further to the right causes underruns unless CDCLK is also bumped.

2026-07-17vfio/pci: clear vdev->msi_perm after freeing it on init failureXiang Mei
vfio_msi_cap_len() lazily allocates the per-device MSI permission table: vdev->msi_perm = kmalloc_obj(struct perm_bits, GFP_KERNEL_ACCOUNT); if (!vdev->msi_perm) return -ENOMEM; ret = init_pci_cap_msi_perm(vdev->msi_perm, len, flags); if (ret) { kfree(vdev->msi_perm); return ret; /* vdev->msi_perm left dangling */ } When init_pci_cap_msi_perm() -> alloc_perm_bits() fails with -ENOMEM, the error path frees vdev->msi_perm but leaves the freed pointer stored in it. vdev->msi_perm is not re-zeroed later because struct vfio_pci_core_device is per-device and persists across open/close cycles, and the vfio_config_init() error path returns without calling vfio_config_free(). So the dangling pointer outlives the failed open. That leads to two use-after-frees on the same device: 1. Reuse. The next vfio_config_init() sees the stale pointer at "if (vdev->msi_perm) return len;" and reuses the freed object. MSI config accesses in vfio_pci_config_rw_single() then dereference and call the freed perm->readfn / perm->writefn function pointers. 2. Double free. A later vfio_config_free() runs free_perm_bits() and kfree() on the already-freed object. Fix it by NULLing vdev->msi_perm after the kfree(), matching the NULL-after-free discipline already used in free_perm_bits() and vfio_config_free().
