Correct sparc64's implementation of FUTEX_OP_ANDN to do a bitwise negate of the oparg parameter before applying the AND operation. All other archs that support FUTEX_OP_ANDN either negate oparg explicitly (frv, ia64, mips, sh, x86), or do so indirectly by using an and-not instruction (powerpc). Since sparc64 has and-not, I chose to use that solution. I've not found any use of FUTEX_OP_ANDN in glibc so the impact of this bug is probably minor. But other user-space components may try to use it so it should still get fixed. Signed-off-by: Mikael Pettersson <mikpe@it.uu.se> Signed-off-by: David S. Miller <davem@davemloft.net> |
