Subject: eloop: Dump a trace when exiting due to SIGALRM
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=289ec0bdfd03dce60853db0b840b185312aba4ff;p=thirdparty%2Fhostap.git

eloop: Dump a trace when exiting due to SIGALRM

We configure a SIGALRM when receiving a signal to exit. If this SIGALRM
is fired, then the process did not properly exit. When this happens,
dump a trace to help with debugging.
