Re: [libvirt] [PATCH 4/4] Implement virDomainSendProcessSignal for LXC driver
Implement the new API for sending signals to processes in a guest
for the LXC driver. Only support sending signals to the init
process for now, because
- The kernel does not appear to expose the mapping between
container PID numbers and host PID numbers anywhere in the
host OS namespace
- There is no race-free validate whether a host PID corresponds
s/race-free/race-free way to/
+ /* We're relying on fact libvirt header signal numbers
+ * are taken from Linux, to avoid mapping
Cute, but at least you documented your assumption. Should you
validate that signum <= SIGRTMAX, though, for a nicer error
than what kill() would give for out-of-range signum?
