Subject: Add SIGALRM to blockable fatal signals.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=85a31d495b3e6649a9c53dfeb42a41e82b5e68d1;p=openvswitch

Add SIGALRM to blockable fatal signals.

We use SIGALRM to limit runtime of dpctl and ofp-discover.  There is no
reason that we should not clean up after it in the same way as any other
catchable signal.  In particular, ofp-discover wants to restore network
device flags on timeout.
