2015-01-06core: add new logic for services to store file descriptors in PID 1Lennart Poettering
With this change it is possible to send file descriptors to PID 1, via sd_pid_notify_with_fds() which PID 1 will store individually for each service, and pass via the usual fd passing logic on next invocation. This is useful for enable daemon reload schemes where daemons serialize their state to /run, push their fds into PID 1 and terminate, restoring their state on next start from the data in /run and passed in from PID 1. The fds are kept by PID 1 as long as no POLLHUP or POLLERR is seen on them, and the service they belong to are either not dead or failed, or have a job queued.

2015-01-05journal: call connect() with dropped privilegesZbigniew Jędrzejewski-Szmek
When systemd starts a service, it first opened /run/systemd/journal/stdout socket, and only later switched to the right user.group (if they are specified). Later on, journald looked at the credentials, and saw root.root, because credentials are stored at the time the socket is opened. As a result, all messages passed over _TRANSPORT=stdout were logged with _UID=0, _GID=0. Drop real uid and gid temporarily to fix the issue.
2015-01-05core: rework counting of running jobsLennart Poettering
Let's unify the code that counts the running jobs a bit, in order to make sure we are less likely to miss one. This is related to this bug: https://bugs.freedesktop.org/show_bug.cgi?id=87349 However, it probably won't fix it fully, and I cannot reproduce the issue. The change also adds an explicit assert change when the counter is off.

2015-01-05util: Do not clear parent mount flags when setting up namespacesTopi Miettinen
When setting up a namespace, mount flags like noexec, nosuid and nodev are cleared, so the mounts always have exec, suid and dev flags enabled. Copy source directory mount flags to target mount when remounting the bind mounts.

2015-01-05fstab-generator: use more appropriate checks for swap and device availabilityLennart Poettering
We always should use the same checks when deciding whether swap support and mounting of devices is supported. Hence, let's make fstab-generator's logic more similar to the usual logic we follow: a) Look for /proc/swaps and no container support before activating swaps. b) Look for /sys being writable befire supporting device mounts.

2015-01-05util: Fix signedness error in lines(), match implementationsColin Walters
Regression introduced by ed757c0cb03eef50e8d9aeb4682401c3e9486f0b Mirror the implementation of columns(), since the fd_columns() functions returns a negative integer for errors. Also fix columns() to return the unsigned variable instead of the signed intermediary (they're the same, but better to be explicit).

journal file headers Since the file headers might be replaced by zeroed pages now due to sigbus we should make sure we don't end up dividing by zero because we don't check values read from journal file headers for changes.

2015-01-05journal: install sigbus handler for journal tools tooLennart Poettering
This makes them robust regarding truncation. Ideally, we'd export this as an API, but given how messy SIGBUS handling is, and the uncertain ownership logic of signal handlers we should not do this (unless libc one day invents a scheme how to sanely install SIGBUS handlers for specific memory areas only). However, for now we can still make all our own tools robust. Note that external tools will only have read-access to the journal anyway, where SIGBUS is much more unlikely, given that only writes are subject to disk full problems.

2015-01-05journald: process SIGBUS for the memory maps we set upLennart Poettering
Even though we use fallocate() it appears that file systems like btrfs will trigger SIGBUS on certain low-disk-space situation. We should handle that, hence catch the signal, add it to a list of invalidated pages, and replace the page with an empty memory area. After each write check if SIGBUS was triggered, and consider the write invalid if it was. This should make journald a lot more robust with file systems where fallocate() is not reliable, for example all CoW file systems (btrfs...), where changing written data can fail with disk full errors. https://bugzilla.redhat.com/show_bug.cgi?id=1045810

2015-01-01mount: do not use -n when running in --user modeZbigniew Jędrzejewski-Szmek
-n is only allowed for root. /etc/mtab is nowadays almost always a link to /proc/, so in practice this does not really matter too much, but should allow .mount units to work in --user mode. https://bugs.freedesktop.org/show_bug.cgi?id=87602

2014-12-31lldp: fix sd_lldp_save()David Herrmann
Fix a bunch of needless memzero() calls, a bunch of use-after-free regarding _cleanup_free_ and drop unused variables. Hint: Do NOT use _cleanup_free_ for temporary strappend() helpers that are freed multiple times. All you safe is the last free() call, which is really not worth the trouble resetting it to NULL all the time.
2014-12-31lldp: fix uninitialized cleanup var #2David Herrmann
Another uninitialized variable marked as _cleanup_. Set it to NULL to avoid accessing uninitialized memory.
2014-12-31lldp: fix uninitialized cleanup varDavid Herrmann
Make sure to set _cleanup_ variables to NULL. Otherwise, we free uninitialized objects.
2014-12-31import: fix mem-leak in CurlGlueDavid Herrmann
Make sure to actually free the underlying object in CurlGlue unref.
2014-12-31lldp: fix double freeDavid Herrmann
'k' is marked as _cleanup_free_ so reset it to NULL if we free it explicitly.
2014-12-31networkctl: fix strappend() error checkingDavid Herrmann
Make sure to test the right variable for NULL.
2014-12-31network: add malloc-assertion in testDavid Herrmann
Make sure malloc() really returns non-NULL in lldp test.

2014-12-31Revert commit f131770b "tree-wide: spelling fixes"David Herrmann
This partially reverts: commit f131770b1465fbf423881f16ba85523a05f846fe Author: Veres Lajos <vlajos@gmail.com> Date: Mon Dec 29 09:45:58 2014 +0000 tree-wide: spelling fixes The commit in question changed a binary file. I didn't look at the diff in particular, so I have no idea what exactly was changed. However, the file is generated and it looked highly suspiciuous. Therefore, I reverted that part. Note that this is generated by "make update-unifont" so really no reason to touch at all.
