Sort the includes accoding to the new coding style.
2015-10-31nspawn: fix minor memory leakLennart Poettering
When rebooting nspawn containers about 400 times we'd otherwise hit the fd limit and refuse further reboots.
2015-10-27util-lib: split out allocation calls into alloc-util.[ch]Lennart Poettering
2015-10-25util-lib: split out fd-related operations into fd-util.[ch]Lennart Poettering
There are more than enough to deserve their own .c file, hence move them over.
2015-10-07machinectl: fix race when opening new shells with "machinectl shell"Lennart Poettering
Previously, we'd allocate the TTY, spawn a service on it, but immediately start processing the TTY and forwarding it to whatever the commnd was started on. This is however problematic, as the TTY might get actually opened only much later by the service. We'll hence first get EIOs on the master as the other side is still closed, and hence considered it hung up and terminated the session. With this change we add a flag to the pty forwarding logic: PTY_FORWARD_IGNORE_INITIAL_VHANGUP. If set, we'll ignore all hangups (i.e. EIOs) on the master PTY until the first byte is successfully read. From that point on we consider a hangup/EIO a regular connection termination. This way, we handle the race: when we get EIO initially we'll ignore it, until the connection is properly set up, at which time we start honouring it.
2015-03-13Use space after a silencing (void)Zbigniew Jędrzejewski-Szmek
We were using a space more often than not, and this way is codified in CODING_STYLE.
2015-02-23remove unused includesThomas Hindoe Paaboel Andersen
This patch removes includes that are not used. The removals were found with include-what-you-use which checks if any of the symbols from a header is in use.
2015-02-18nspawn: when connected to pipes for stdin/stdout, pass them as-is to PID 1Lennart Poettering
Previously we always invoked the container PID 1 on /dev/console of the container. With this change we do so only if nspawn was invoked interactively (i.e. its stdin/stdout was connected to a TTY). In all other cases we directly pass through the fds unmodified. This has the benefit that nspawn can be added into shell pipelines. https://bugs.freedesktop.org/show_bug.cgi?id=87732

2014-11-28treewide: use log_*_errno whenever %m is in the format stringMichal Schmidt
If the format string contains %m, clearly errno must have a meaningful value, so we might as well use log_*_errno to have ERRNO= logged. Using: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\((".*%m.*")/log_\1_errno(errno, \2/' Plus some whitespace, linewrap, and indent adjustments.
2014-11-05shared: ptyfwd - make coverity happyTom Gundersen
Explicitly ignore return value of ioctl to set window size. Fixes CID#1250804 and CID#1250800.
2014-10-31ptyforward: rework PTY forwarder logic used by nspawn to utilize the normal ↵Lennart Poettering
event loop We really should not run manual event loops anymore, but standardize on sd_event, so that we can run sd_bus connections from it eventually.
2014-02-21ptyfwd: reset nonblocking modeLennart Poettering
Apparently bash doesn't turn off non-blocking mode on stdin/stdout when reading from it, so be nice to bash. Ideally bash would do this on its own for robustness reasons, though. https://bugs.freedesktop.org/show_bug.cgi?id=70622
2013-12-18Revert "ptyfwd: make master terminal attributes raw, too"Lennart Poettering
This reverts commit e7d43b3cc30764138c90eaaf95d3d8f49e448890. This broke the console terminal when booting up a container, so let's not do this.

2013-12-11ptyfwd: Don't set the output prop of stdin, nor the input props of stdout.Luke Shumaker
It was calling cfmakeraw(3) on the properties for STDIN_FILENO; cfmakeraw sets both input and output properties. If (and only if) stdin and stdout are the same device is this correct. Otherwise, we must change only the input properties of stdin, and only the output properties of stdout.
