Linux kernel stable tree (mirror) https://git.radix-linux.su/kernel/linux.git/atom?h=v7.0.10 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 *".

While at it, also sort the include lists alphabetically. (Keep asm/irqflags.h last, as otherwise it doesn't build on alpha.) This handles all of lib/crypto/, but not arch/*/lib/crypto/. The exports in arch/*/lib/crypto/ will go away when the code is properly integrated into lib/crypto/ as planned.

Add the checks and change the API to allow errors to be returned.

Most of it is no longer needed since sm2 has been removed. However, the following functions have been kept as they have developed other uses: mpi_copy mpi_mod mpi_test_bit mpi_set_bit mpi_rshift mpi_add mpi_sub mpi_addm mpi_subm mpi_mul mpi_mulm mpi_tdiv_r mpi_fdiv_r Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> 2023-08-11T11:19:27+00:00 Herbert Xu herbert@gondor.apana.org.au 2023-08-04T09:24:34+00:00 urn:sha1:2a598d0b2800aa23ba51adcf060cec524aaa63b2 As lib/mpi is mostly used by crypto code, move it under lib/crypto so that patches touching it get directed to the right mailing list.
