Backports of patch from systemd git to stable distributions
aa11e28bf2
Quite often we need to set up a number of fds as stdin/stdout/stderr of a process we are about to start. Add a generic implementation for a routine doing that that takes care to do so properly: 1. Can handle the case where stdin/stdout/stderr where previously closed, and the fds to set as stdin/stdout/stderr hence likely in the 0..2 range. handling this properly is nasty, since we need to first move the fds out of this range in order to later move them back in, to make things fully robust. 2. Can optionally open /dev/null in case for one or more of the fds, in a smart way, sharing the open file if possible between multiple of the fds. 3. Guarantees that O_CLOEXEC is not set on the three fds, even if the fds already were in the 0..2 range and hence possibly weren't moved. |
