Subjectpossible kernel bug in signal transit.
From
Date
Hello All

I analyze kernel vanila 2.6.4 and found one possible bug in
__kill_pg_info function.

for_each_task_pid(pgrp, PIDTYPE_PGID, p, l, pid) {
err = group_send_sig_info(sig, info, p);
if (retval)
retval = err;
}
but I think if (retval) is incorrect check. possible this cycle must be
for_each_task_pid(pgrp, PIDTYPE_PGID, p, l, pid) {
err = group_send_sig_info(sig, info, p);
if (ret) {
retval = err;
break;
}
}
because in original variant me assign to retval only first value from
ret and other be ignored if this value be 0.
