2025-06-26MAINTAINERS: add Lorenzo as THP co-maintainerLorenzo Stoakes1-1/+1
I am doing a great deal of review and getting ever more involved in THP with intent to do more so in future also, so add myself as co-maintainer to help David with workload.

2025-06-26selftests/mm: fix validate_addr() helperDev Jain1-2/+5
validate_addr() checks whether the address returned by mmap() lies in the low or high VA space, according to whether a high addr hint was passed or not. The fix commit mentioned below changed the code in such a way that this function will always return failure when passed high_addr == 1; addr will be >= HIGH_ADDR_MARK always, we will fall down to "if (addr > HIGH_ADDR_MARK)" and return failure. Fix this.

2025-06-26crashdump: add CONFIG_KEYS dependencyArnd Bergmann1-0/+1
The dm_crypt code fails to build without CONFIG_KEYS: kernel/crash_dump_dm_crypt.c: In function 'restore_dm_crypt_keys_to_thread_keyring': kernel/crash_dump_dm_crypt.c:105:9: error: unknown type name 'key_ref_t'; did you mean 'key_ref_put'? There is a mix of 'select KEYS' and 'depends on KEYS' in Kconfig, so there is no single obvious solution here, but generally using 'depends on' makes more sense and is less likely to cause dependency loops.

2025-06-26fuse: fix runtime warning on truncate_folio_batch_exceptionals()Haiyue Wang1-0/+4
The WARN_ON_ONCE is introduced on truncate_folio_batch_exceptionals() to capture whether the filesystem has removed all DAX entries or not. And the fix has been applied on the filesystem xfs and ext4 by the commit 0e2f80afcfa6 ("fs/dax: ensure all pages are idle prior to filesystem unmount").

memcg_path_store() assigns a newly allocated memory buffer to filter->memcg_path, without deallocating the previously allocated and assigned memory buffer. As a result, users can leak kernel memory by continuously writing a data to memcg_path DAMOS sysfs file. Fix the leak by deallocating the previously set memory buffer.

2025-06-26mm/alloc_tag: fix the kmemleak false positive issue in the allocation of the ↵Hao Ge3-1/+25
percpu variable tag->counters When loading a module, as long as the module has memory allocation operations, kmemleak produces a false positive report that resembles the following: unreferenced object (percpu) 0x7dfd232a1650 (size 16): comm "modprobe", pid 1301, jiffies 4294940249 hex dump (first 16 bytes on cpu 2): 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace (crc 0): kmemleak_alloc_percpu+0xb4/0xd0 pcpu_alloc_noprof+0x700/0x1098 load_module+0xd4/0x348 codetag_module_init+0x20c/0x450 codetag_load_module+0x70/0xb8 load_module+0xef8/0x1608 init_module_from_file+0xec/0x158 idempotent_init_module+0x354/0x608 __arm64_sys_finit_module+0xbc/0x150 invoke_syscall+0xd4/0x258 el0_svc_common.constprop.0+0xb4/0x240 do_el0_svc+0x48/0x68 el0_svc+0x40/0xf8 el0t_64_sync_handler+0x10c/0x138 el0t_64_sync+0x1ac/0x1b0 This is because the module can only indirectly reference alloc_tag_counters through the alloc_tag section, which misleads kmemleak. However, we don't have a kmemleak ignore interface for percpu allocations yet. So let's create one and invoke it for tag->counters.

2025-06-26mm/hugetlb: remove unnecessary holding of hugetlb_lockGe Yang1-37/+17
In isolate_or_dissolve_huge_folio(), after acquiring the hugetlb_lock, it is only for the purpose of obtaining the correct hstate, which is then passed to alloc_and_dissolve_hugetlb_folio(). alloc_and_dissolve_hugetlb_folio() itself also acquires the hugetlb_lock. We can have alloc_and_dissolve_hugetlb_folio() obtain the hstate by itself, so that isolate_or_dissolve_huge_folio() no longer needs to acquire the hugetlb_lock. In addition, we keep the folio_test_hugetlb() check within isolate_or_dissolve_huge_folio(). By doing so, we can avoid disrupting the normal path by vainly holding the hugetlb_lock. replace_free_hugepage_folios() has the same issue, and we should address it as well. Addresses a possible performance problem which was added by the hotfix 113ed54ad276 ("mm/hugetlb: fix kernel NULL pointer dereference when replacing free hugetlb folios").

2025-06-21i2c: k1: check for transfer errorAlex Elder1-1/+1
If spacemit_i2c_xfer_msg() times out waiting for a message transfer to complete, or if the hardware reports an error, it returns a negative error code (-ETIMEDOUT, -EAGAIN, -ENXIO. or -EIO). The sole caller of spacemit_i2c_xfer_msg() is spacemit_i2c_xfer(), which is the i2c_algorithm->xfer callback function. It currently does not save the value returned by spacemit_i2c_xfer_msg(). The result is that transfer errors go unreported, and a caller has no indication anything is wrong. When this code was out for review, the return value *was* checked in early versions. But for some reason, that assignment got dropped between versions 5 and 6 of the series, perhaps related to reworking the code to merge spacemit_i2c_xfer_core() into spacemit_i2c_xfer(). Simply assigning the value returned to "ret" fixes the problem.

2025-06-21smb: client: fix first command failure during re-negotiationzhangjian1-0/+1
after fabc4ed200f9, server_unresponsive add a condition to check whether client need to reconnect depending on server->lstrp. When client failed to reconnect for some time and abort connection, server->lstrp is updated for the last time. In the following scene, server->lstrp is too old. This cause next command failure in re-negotiation rather than waiting for re-negotiation done. 1. mount -t cifs -o username=Everyone,echo_internal=10 //$server_ip/export /mnt 2. ssh $server_ip "echo b > /proc/sysrq-trigger &" 3. ls /mnt 4. sleep 21s 5. ssh $server_ip "service firewalld stop" 6. ls # return EHOSTDOWN If the interval between 5 and 6 is too small, 6 may trigger sending negotiation request. Before backgrounding cifsd thread try to receive negotiation response from server in cifs_readv_from_socket, server_unresponsive may trigger cifs_reconnect which cause 6 to be failed: ls thread ---------------- smb2_negotiate server->tcpStatus = CifsInNegotiate compound_send_recv wait_for_compound_request cifsd thread ---------------- cifs_readv_from_socket server_unresponsive server->tcpStatus == CifsInNegotiate && jiffies > server->lstrp + 20s cifs_reconnect cifs_abort_connection: mid_state = MID_RETRY_NEEDED ls thread ---------------- cifs_sync_mid_result return EAGAIN smb2_negotiate return EHOSTDOWN Though server->lstrp means last server response time, it is updated in cifs_abort_connection and cifs_get_tcp_session. We can also update server->lstrp before switching into CifsInNegotiate state to avoid failure in 6.

2025-06-20rcu: Return early if callback is not specifiedUladzislau Rezki (Sony)1-0/+4
Currently the call_rcu() API does not check whether a callback pointer is NULL. If NULL is passed, rcu_core() will try to invoke it, resulting in NULL pointer dereference and a kernel crash. To prevent this and improve debuggability, this patch adds a check for NULL and emits a kernel stack trace to help identify a faulty caller.
