lockd: Relocate include/linux/lockd/lockd.h

2026-03-30T01:25:09+00:00

Headers placed in include/linux/ form part of the kernel's internal API and signal to subsystem maintainers that other parts of the kernel may depend on them. By moving lockd.h into fs/lockd/, lockd becomes a more self-contained module whose internal interfaces are clearly distinguished from its public contract with the rest of the kernel. This relocation addresses a long-standing XXX comment in the header itself that acknowledged the file's misplacement. Future changes to lockd internals can now proceed with confidence that external consumers are not inadvertently coupled to implementation details. Reviewed-by: Jeff Layton Signed-off-by: Chuck Lever

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

lockd: adapt to breakup of struct file_lock

2024-02-05T12:11:43+00:00

Most of the existing APIs have remained the same, but subsystems that access file_lock fields directly need to reach into struct file_lock_core now.

lockd: fix races in client GRANTED_MSG wait logic

2023-04-26T13:05:00+00:00

After the wait for a grant is done (for whatever reason), nlmclnt_block updates the status of the nlm_rqst with the status of the block. At the point it does this, however, the block is still queued its status could change at any time. This is particularly a problem when the waiting task is signaled during the wait. We can end up giving up on the lock just before the GRANTED_MSG callback comes in, and accept it even though the lock request gets back an error, leaving a dangling lock on the server. Since the nlm_wait never lives beyond the end of nlmclnt_lock, put it on the stack and add functions to allow us to enqueue and dequeue the block. Enqueue it just before the lock/wait loop, and dequeue it just after we exit the loop instead of waiting until the end of the function. Also, scrape the status at the time that we dequeue it to ensure that it's final.

lockd: move struct nlm_wait to lockd.h

The next patch needs struct nlm_wait in fs/lockd/clntproc.c, so move the definition to a shared header file. As an added clean-up, drop the unused b_reclaim field. Signed-off-by: Jeff Layton Signed-off-by: Chuck Lever
