2023-09-30wifi: mt76: mt7921e: Support MT7992 IP in Xiaomi Redmibook 15 Pro (2023)Ingo Rohloff
In the Xiaomi Redmibook 15 Pro (2023) laptop I have got, a wifi chip is used, which according to its PCI Vendor ID is from "ITTIM Technology". This chip works flawlessly with the mt7921e module. The driver doesn't bind to this PCI device, because the Vendor ID from "ITTIM Technology" is not recognized. This patch adds the PCI Vendor ID from "ITTIM Technology" to the list of PCI Vendor IDs and lets the mt7921e driver bind to the mentioned wifi chip.

2023-09-30wifi: mt76: use atomic iface iteration for pre-TBTT workJohannes Berg
In addition to the previous series I posted, over time I'd also like to get rid of the iflist_mtx in mac80211. That isn't easy now since lots of places use iteration and would have to be audited, but even a cursory look suggests that mt76 might be more problematic than most since holding the wiphy lock for the latency-sensitive pre-TBTT work could be an issue. Convert the pre-TBTT work to use atomic iteration and then sending the device commands outside of it.

A reset should only be performed if these conditions are true and if there is no rx activity as well. Reset the counter whenever a rx interrupt occurs. In order to also deal with a fully loaded CPU that leaves interrupts disabled with continuous NAPI polling, also check for pending rx interrupts in the function itself.

2023-09-30bpf: Use kmalloc_size_roundup() to adjust size_indexHou Tao
Commit d52b59315bf5 ("bpf: Adjust size_index according to the value of KMALLOC_MIN_SIZE") uses KMALLOC_MIN_SIZE to adjust size_index, but as reported by Nathan, the adjustment is not enough, because __kmalloc_minalign() also decides the minimal alignment of slab object as shown in new_kmalloc_cache() and its value may be greater than KMALLOC_MIN_SIZE (e.g., 64 bytes vs 8 bytes under a riscv QEMU VM). Instead of invoking __kmalloc_minalign() in bpf subsystem to find the maximal alignment, just using kmalloc_size_roundup() directly to get the corresponding slab object size for each allocation size. If these two sizes are unmatched, adjust size_index to select a bpf_mem_cache with unit_size equal to the object_size of the underlying slab cache for the allocation size.

hugetlb_reparenting_test.sh that may cause error According to the awk manual, the -e option does not need to be specified in front of 'program' (unless you need to mix program-file).

2023-09-29mm: mempolicy: keep VMA walk if both MPOL_MF_STRICT and MPOL_MF_MOVE are ↵Yang Shi
specified When calling mbind() with MPOL_MF_{MOVE|MOVEALL} | MPOL_MF_STRICT, kernel should attempt to migrate all existing pages, and return -EIO if there is misplaced or unmovable page. Then commit 6f4576e3687b ("mempolicy: apply page table walker on queue_pages_range()") messed up the return value and didn't break VMA scan early ianymore when MPOL_MF_STRICT alone. The return value problem was fixed by commit a7f40cfe3b7a ("mm: mempolicy: make mbind() return -EIO when MPOL_MF_STRICT is specified"), but it broke the VMA walk early if unmovable page is met, it may cause some pages are not migrated as expected. The code should conceptually do: if (MPOL_MF_MOVE|MOVEALL) scan all vmas try to migrate the existing pages return success else if (MPOL_MF_MOVE* | MPOL_MF_STRICT) scan all vmas try to migrate the existing pages return -EIO if unmovable or migration failed else /* MPOL_MF_STRICT alone */ break early if meets unmovable and don't call mbind_range() at all else /* none of those flags */ check the ranges in test_walk, EFAULT without mbind_range() if discontig. Fixed the behavior.

2023-09-29mm/damon/vaddr-test: fix memory leak in damon_do_test_apply_three_regions()Jinjie Ruan
When CONFIG_DAMON_VADDR_KUNIT_TEST=y and making CONFIG_DEBUG_KMEMLEAK=y and CONFIG_DEBUG_KMEMLEAK_AUTO_SCAN=y, the below memory leak is detected. Since commit 9f86d624292c ("mm/damon/vaddr-test: remove unnecessary variables"), the damon_destroy_ctx() is removed, but still call damon_new_target() and damon_new_region(), the damon_region which is allocated by kmem_cache_alloc() in damon_new_region() and the damon_target which is allocated by kmalloc in damon_new_target() are not freed. And the damon_region which is allocated in damon_new_region() in damon_set_regions() is also not freed. So use damon_destroy_target to free all the damon_regions and damon_target. unreferenced object 0xffff888107c9a940 (size 64): comm "kunit_try_catch", pid 1069, jiffies 4294670592 (age 732.761s) hex

2023-09-29mm, memcg: reconsider kmem.limit_in_bytes deprecationMichal Hocko
This reverts commits 86327e8eb94c ("memcg: drop kmem.limit_in_bytes") and partially reverts 58056f77502f ("memcg, kmem: further deprecate kmem.limit_in_bytes") which have incrementally removed support for the kernel memory accounting hard limit. Unfortunately it has turned out that there is still userspace depending on the existence of memory.kmem.limit_in_bytes [1]. The underlying functionality is not really required but the non-existent file just confuses the userspace which fails in the result. The patch to fix this on the userspace side has been submitted but it is hard to predict how it will propagate through the maze of 3rd party consumers of the software. Now, reverting alone 86327e8eb94c is not an option because there is another set of userspace which cannot cope with ENOTSUPP returned when writing to the file. Therefore we have to go and revisit 58056f77502f as well. There are two ways to go ahead. Either we give up on the deprecation and fully revert 58056f77502f as well or we can keep kmem.limit_in_bytes but make the write a noop and warn about the fact. This should work for both known breaking workloads which depend on the existence but do not depend on the hard limit enforcement. Note to backporters to stable trees. a8c49af3be5f ("memcg: add per-memcg total kernel memory stat") introduced in 4.18 has added memcg_account_kmem so the accounting is not done by obj_cgroup_charge_pages directly for v1 anymore. Prior kernels need to add it explicitly (thanks to Johannes for pointing this out).

While stress-testing zswap a memory corruption was happening when writing back pages. __frontswap_store used to check for duplicate entries before attempting to store a page in zswap, this was because if the store fails the old entry isn't removed from the tree.
