We should count the terminating NUL byte as part of the ctx_len. Otherwise, UBSAN logs a warning: UBSAN: array-index-out-of-bounds in security/selinux/xfrm.c:99:14 index 60 is out of range for type 'char [*]' The allocation itself is correct so there is no actual out of bounds indexing, just a warning.
