autofs-5.1.8 - make signal handling consistent
|
||
|
|
|
||
|
|
From: Ian Kent <raven@themaw.net>
|
||
|
|
|
||
|
|
There's a mixture of usage of sigprocmask() and pthread_sigmask(), change
|
||
|
|
to use the pthread versions of this for correctness.
|
||
|
|
|
||
|
|
The only exception to this is reset_signals() which is done in a forked
|
||
|
|
process that is single threaded so it's valid to keep them as they are.
