treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28Z

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

fs: add setlease to generic_ro_fops and read-only filesystem directory operations

2026-01-12T09:55:45Z

Add the setlease file_operation to generic_ro_fops, which covers file operations for several read-only filesystems (BEFS, EFS, ISOFS, QNX4, QNX6, CRAMFS, FREEVXFS). Also add setlease to the directory file_operations for these filesystems. A future patch will change the default behavior to reject lease attempts with -EINVAL when there is no setlease file operation defined. Add generic_setlease to retain the ability to set leases on these filesystems.

Coccinelle-based conversion to use ->i_state accessors

All places were patched by coccinelle with the default expecting that ->i_lock is held, afterwards entries got fixed up by hand to use unlocked variants as needed.

fs/qnx6: Fix building with GCC 15

2024-12-03T09:40:36Z

qnx6_checkroot() had been using weirdly spelled initializer - it needed to initialize 3-element arrays of char and it used NUL-padded 3-character string literals (i.e. 4-element initializers, with completely pointless zeroes at the end). That had been spotted by gcc-15[*]; prior to that gcc quietly dropped the 4th element of initializers. However, none of that had been needed in the first place - all this array is used for is checking that the first directory entry in root directory is "." and the second - "..". The check had been expressed as a loop, using that match_root[] array. Since there is no chance that we ever want to extend that list of entries, the entire thing is much too fancy for its own good; what we need is just a couple of explicit memcmp() and that's it.

qnx6: Convert qnx6_find_entry() to qnx6_find_ino()

2024-08-07T09:31:55Z

It's hard to return a directory entry from qnx6_find_entry() because it might be a long dir_entry with a different format. So stick with the convention of returning an inode number, but rename it to qnx6_find_ino() to reflect what it actually does, and move the call to qnx6_put_page() inside the function which lets us get rid of the res_page parameter.
