Eric W. Biederman 1dfd1711de signal/bpfilter: Fix bpfilter_kernl to use send_sig not force_sig ... The locking in force_sig_info is not prepared to deal with a task that exits or execs (as sighand may change). As force_sig is only built to handle synchronous exceptions. Further the function force_sig_info changes the signal state if the signal is ignored, or blocked or if SIGNAL_UNKILLABLE will prevent the delivery of the signal. The signal SIGKILL can not be ignored and can not be blocked and SIGNAL_UNKILLABLE won't prevent it from being delivered. So using force_sig rather than send_sig for SIGKILL is pointless. Because it won't impact the sending of the signal and and because using force_sig is wrong, replace force_sig with send_sig. Cc: Alexei Starovoitov <ast@kernel.org> Cc: David S.
