crypto: marvell/cesa - Fix type mismatch warning

2023-07-27T06:37:18Z

[ Upstream commit efbc7764c4446566edb76ca05e903b5905673d2e ] Commit df8fc4e934c1 ("kbuild: Enable -fstrict-flex-arrays=3") uncovered a type mismatch in cesa 3des support that leads to a memcpy beyond the end of a structure: In function 'fortify_memcpy_chk', inlined from 'mv_cesa_des3_ede_setkey' at drivers/crypto/marvell/cesa/cipher.c:307:2: include/linux/fortify-string.h:583:25: error: call to '__write_overflow_field' declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Werror=attribute-warning] 583 | __write_overflow_field(p_size_field, size); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This is probably harmless as the actual data that is copied has the correct type, but clearly worth fixing nonetheless.
