nspawn: always setup machine id (v3)
2016-04-11nspawn: always setup machine idMichal Sekletar
We check /etc/machine-id of the container and if it is already populated we use value from there, possibly ignoring value of --uuid option from the command line. When dealing with R/O image we setup transient machine id. Once we determined machine id of the container, we use this value for registration with systemd-machined and we also export it via container_uuid environment variable. As registration with systemd-machined is done by the main nspawn process we communicate container machine id established by setup_machine_id from outer child to the main process by unix domain socket. Similarly to PID of inner child.

It might be nicer to propagate the error to the caller, but that'd be a bigger refactoring. This shouldn't really fail, so just add an assert. CID #1349697.

2016-04-07core: downgrade warning about duplicate device names againVladimir Panteleev
Pull request #2412 seemed to have unintentionally reverted 5259bcf6a638d8d489db1ddefd55327aa15f3e51, thus reintroducing https://bugs.freedesktop.org/show_bug.cgi?id=90386. This commit reverts that part of the commit, changing the log level to debug again.
2016-04-07lldp: replace if with assert_ccZbigniew Jędrzejewski-Szmek
LLDP_TX_HOLD or one of the other variables might be changed in the future resulting in a silent error here if the if was just removed. Replacement for #2983.

2016-04-05journal-upload: Update watchdog while in curl_easy_performKlearchos Chaloulos
It is observed that a combination of high log throughput, low I/O speed on journal remote side and many nodes uploading simultaneously caused the journal-upload process to dump core because of watchdog starvation. This is caused because journal-upload stays in curl_easy_perform(), because it cannot upload fast enough to reach the end of the journal. Currently journal-upload will return from curl_easy_perform() only when the end of the journal is reached. Therefore a check is added in journal_input_callback(), which will update the watchdog if the elapsed time since the start of the uploading process is greater than WATCHDOG_USEC/2.

Fixes: #457
2016-04-05polkit: don't start polkit agent when running as rootMartin Pitt
On the server side we already bypass the polkit checks if the caller is root (see the sd_bus_query_sender_privilege() call in bus_verify_polkit_async()). So there is no reason to invoke polkit when running systemctl/machinectl/loginctl/timedatectl as root. Fixes #2748
2016-04-05sd-device: fix crash if a device has many tags or devlinksMartin Pitt
strjoina() is unsafe to be used in an unbounded loop as alloca() has no error reporting. Thus devices with a large number of tags or devlinks trigger a segfault in device_properties_prepare() due to overflowing the stack. Rewrite the building of the "tags" and "devlinks" strings using GREEDY_REALLOC() and strpcpy() to work with arbitrarily long strings. This also avoids re-copying the entire string in each loop iteration. Before this commit we always appended one final ":" to "tags". Change this to start with an iniital ":" and for each tag append instead of prepend a ":". This unifies what happens for the first and all subsequent tags so that we can use a for loop. Fixes #2954
2016-04-04Address code-review items for pull-request #2890Vinay Kulkarni
1. Replace strtol with unhexchar, verified with valid and invalid DUID strings. 2. Fix logging to use log_syntax instead of log_error. 3. On error reading DUID, ignore read and preserve previous state. 4. Fix man-pages to use markup, remove options not yet implemented. 5. Remove spurious header line in new files.

With this option, systemctl will only print the rhs in show: $ systemctl show -p Wants,After systemd-journald --value systemd-journald.socket ... systemd-journald-dev-log.socket ... This is useful in scripts, because the need to call awk or similar is removed.

*.localdomain != localhost
2016-04-04*.localdomain != localhostDavid R. Hedges
".localdomain" is not a reserved suffix (or prefix). I'm not aware of any product expecting *.localdomain to resolve to localhost, however I am aware of at least one product that defaults to ".localdomain" as its DNS suffix provided via DHCP (pfSense). This leads to unexpected results when attempting to access a host that's offline (or a host that's online, when nsswitch.conf is [mis-]configured to have myhostname ahead of DNS). Operate on: localhost (and localhost.) *.localhost (and *.localhost.) localhost.localdomain (and localhost.localdomain.) *.localhost.localdomain (and *.localhost.localdomain.) We should not cover: *.localdomain (nor *.localdomain.) localdomain (nor localdomain.)
