2016-10-21systemctl: suppress errors with "show" for nonexistent units and propertiessystemd/v231-4Zbigniew Jędrzejewski-Szmek
Show is documented to be program-parseable, and printing the warning about about a non-existent unit, while useful for humans, broke a lot of scripts. Restore previous behaviour of returning success and printing empty or useless stuff for units which do not exist, and printing empty values for properties which do not exists. With SYSTEMD_LOG_LEVEL=debug, hints are printed, but the return value is still 0. This undoes parts of e33a06a and 3dced37b7 and fixes #3856. We might consider adding an explicit switch to fail on missing units/properties (e.g. --ensure-exists or similar), and make -P foobar equivalent to --ensure-exists --property=foobar.

2016-10-21pid1: don't return any error in manager_dispatch_notify_fd() (#4240)Franck Bui
If manager_dispatch_notify_fd() fails and returns an error then the handling of service notifications will be disabled entirely leading to a compromised system. For example pid1 won't be able to receive the WATCHDOG messages anymore and will kill all services supposed to send such messages. (cherry picked from commit 9987750e7a4c62e0eb8473603150596ba7c3a015)

This undoes 531ac2b234. I acked that patch without looking at the code carefully enough. There are two problems: - we want to process the fds anyway - in principle empty notification messages are valid, and we should process them as usual, including logging using log_unit_debug().

2016-08-19shared/install: when creating symlinks, keep existing relative symlinksZbigniew Jędrzejewski-Szmek
Running preset-all on a system installed from rpms or even created using make install would remove and recreate a lot of symlinks, changing relative to absolute symlinks. In general relative symlinks are nicer, so there is no reason to change them, and those spurious changes were obscuring more interesting stuff. $ make install DESTDIR=/var/tmp/inst1 $ systemctl preset-all --root=/var/tmp/inst1 (before) Removed /var/tmp/inst1/etc/systemd/system/network-online.target.wants/systemd-networkd-wait-online.service.

No functional change intended.
2016-08-19shared/install: ignore unit symlinks when doing preset-allZbigniew Jędrzejewski-Szmek
Before, when interating over unit files during preset-all, behaviour was the following: - if we hit the real unit name first, presets were queried for that name, and that unit was enabled or disabled accordingly, - if we hit an alias first (one of the symlinks chaining to the real unit), we checked the presets using the symlink name, and then proceeded to enable or disable the real unit. E.g. for systemd-networkd.service we have the alias dbus-org.freedesktop.network1.service (/usr/lib/systemd/system/dbus-org.freedesktop.network1.service), but the preset is only for the systemd-networkd.service name. The service would be enabled or disabled pseudorandomly depending on the order of iteration. For "preset", behaviour was analogous: preset on the alias name disabled the service (following the default disable policy), preset on the "real" name applied the presets. With the patch, for "preset" and "preset-all" we silently skip symlinks. This gives mostly the right behaviour, with the limitation that presets on aliases are ignored. I think that presets on aliases are not that common (at least my preset files on Fedora don't exhibit any such usage), and should not be necessary, since whoever installs the preset can just refer to the real unit file. It would be possible to overcome this limitation by gathering a list of names of a unit first, and then checking whether *any* of the names matches the presets list. That would require a significant redesign of the code, and be a lot slower (since we would have to fully read all unit directories to preset one unit) to so I'm not doing that for now. With this patch, two properties are satisfied: - preset-all and preset are idempotent, and the second and subsequent invocations do not produce any changes, - preset-all and preset for a specific name produce the same state for that unit. Fixes #3616.

2016-08-11coredump: treat RLIMIT_CORE below page size as disabling coredumps (#3932)Zbigniew Jędrzejewski-Szmek
The kernel treats values below a certain threshold (minfmt->min_coredump which is initialized do ELF_EXEC_PAGESIZE, which varies between architectures, but is usually the same as PAGE_SIZE) as disabling coredumps [1]. Any core image below ELF_EXEC_PAGESIZE will yield an invalid backtrace anyway [2], so follow the kernel and not try to parse or store such images.

2016-08-09install: follow config_path symlink (#3362)Rhys
Under NixOS, the config_path /etc/systemd/system is a symlink to /etc/static/systemd/system. Commands such as `systemctl list-unit-files` and `systemctl is-enabled` did not work as the symlink was not followed. This does not affect how symlinks are treated within the config_path directory.

2016-08-04core: remember first unit failure, not last unit failureLennart Poettering
Previously, the result value of a unit was overriden with each failure that took place, so that the result always reported the last failure that took place. With this commit this is changed, so that the first failure taking place is stored instead. This should normally not matter much as multiple failures are sufficiently uncommon. However, it improves one behaviour: if we send SIGABRT to a service due to a watchdog timeout, then this currently would be reported as "coredump" failure, rather than the "watchodg" failure it really is. Hence, in order to report information about the type of the failure, and not about the effect of it, let's change this from all unit type to store the first, not the last failure. This addresses the issue pointed out here: https://github.com/systemd/systemd/pull/3818#discussion_r73433520
2016-08-04nss-systemd: resolve root/nobody staticallyLennart Poettering
Let's extend nss-systemd to also synthesize user/group entries for the UIDs/GIDs 0 and 65534 which have special kernel meaning. Given that nss-systemd is listed in /etc/nsswitch.conf only very late any explicit listing in /etc/passwd or /etc/group takes precedence. This functionality is useful in minimal container-like setups that lack /etc/passwd files (or only have incompletely populated ones).

read_full_stream() _always_ allocated twice the memory needed, due to only breaking the realloc() && fread() loop when fread() returned 0, requiring another iteration and exponentially enlarged buffer just to discover the EOF condition. This also caused file sizes >2MiB && <= 4MiB to erroneously be treated as E2BIG, due to the inappropriately doubled buffer size exceeding 4*1024*1024. Also made the 4*1024*1024 magic number a READ_FULL_BYTES_MAX constant.
