Gaosheng Cui fcbd2b3368 capabilities: fix undefined behavior in bit shift for CAP_TO_MASK ... [ Upstream commit 46653972e3 ] Shifting signed 32-bit value by 31 bits is undefined, so changing significant bit to unsigned. The UBSAN warning calltrace like below: UBSAN: shift-out-of-bounds in security/commoncap.c:1252:2 left shift of 1 by 31 places cannot be represented in type 'int' Call Trace: <TASK> dump_stack_lvl+0x7d/0xa5 dump_stack+0x15/0x1b ubsan_epilogue+0xe/0x4e __ubsan_handle_shift_out_of_bounds+0x1e7/0x20c cap_task_prctl+0x561/0x6f0 security_task_prctl+0x5a/0xb0 __x64_sys_prctl+0x61/0x8f0 do_syscall_64+0x58/0x80 entry_SYSCALL_64_after_hwframe+0x63/0xcd </TASK> Fixes: e338d263a7 ("Add 64-bit capability support to the kernel") Signed-off-by: Gaosheng Cui <cuigaosheng1@huawei.com> Acked-by: Andrew G.
