Linux kernel stable tree (mirror) https://git.radix-linux.su/kernel/linux.git/atom?h=v7.0-rc7 2026-02-22T01:09:51+00:00 2026-02-22T01:09:51+00:00 Linus Torvalds torvalds@linux-foundation.org 2026-02-22T00:37:42+00:00 urn:sha1:bf4afc53b77aeaa48b5409da5c8da6bb4eff7f43 This was done entirely with mindless brute force, using git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' | xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/' to convert the new alloc_obj() users that had a simple GFP_KERNEL argument to just drop that argument. Note that due to the extreme simplicity of the scripting, any slightly more complex cases spread over multiple lines would not be triggered: they definitely exist, but this covers the vast bulk of the cases, and the resulting diff is also then easier to check automatically. For the same reason the 'flex' versions will be done as a separate conversion.

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 *".

Support for benchmarking the kernel's Poly1305 code is now provided by the poly1305 kunit test.

Whether this has ever belonged upstream is questionable. Either way, ansi_cprng is no longer usable for this purpose, since it's been superseded by the more modern algorithms in crypto/drbg.c, and FIPS itself no longer allows it. (NIST SP 800-131A Rev 1 (2015) says that RNGs based on ANSI X9.31 will be disallowed after 2015. NIST SP 800-131A Rev 2 (2019) confirms they are now disallowed.) Therefore, there is no reason to keep it around.

POLYVAL remains supported via lib/crypto/, where it has a KUnit test suite instead.
