tcmu_read_config(): check read() return value. #656

Closed maurizio-lombardi closed 3 years ago

maurizio-lombardi commented 3 years ago

tcmu-runner doesn't work correctly on Fedora 34 because it enters an infinite loop while reading the /etc/tcmu/tcmu.conf config file. The reason is that tcmu_read_config() doesn't check the read() return value, relying only on errno's value, but the latter should only be checked when read() returns -1.
