The rfc4106 encrypy/decrypt helper functions cause an annoying false-positive warning in allmodconfig if we turn on -Wmaybe-uninitialized warnings again: arch/x86/crypto/aesni-intel_glue.c: In function ‘helper_rfc4106_decrypt’: include/linux/scatterlist.h:67:31: warning: ‘dst_sg_walk.sg’ may be used uninitialized in this function [-Wmaybe-uninitialized] The problem seems to be that the compiler doesn't track the state of the 'one_entry_in_sg' variable across the kernel_fpu_begin/kernel_fpu_end section. This takes the easy way out by adding a bogus initialization, which should be harmless enough to get the patch into v4.9 so we can turn on this warning again by default without producing useless output. A follow-up patch for v4.10 rearranges the code to make the warning go away. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |
