Subject: [PATCH] Fix fortify_fatal issue during DNSServiceProcessResult()
|
|
|
|
fd was checked at beginnig of DNSServiceProcessResult()
|
|
but fd was changed to -1. So, fortify_fatal was occured
|
|
when FD_SET() was called.
|
|
Abort message: 'FORTIFY: FD_SET: file descriptor -1 < 0'
|
|
|
|
Test: Build
|
