Install: correctly report symlink creations
|
|
* core/unit: extract checking of stat paths into helper function
The same code was repeated three times.
* core: treat masked files as "unchanged"
systemctl prints the "unit file changed on disk" warning
for a masked unit. I think it's better to print nothing in that
case.
When a masked unit is loaded, set mtime as 0. When checking
if a unit with mtime of 0 needs reload, check that the mask
is still in place.
* test-dnssec: fix build without gcrypt
Also reorder the test functions to follow the way they are called
from main().

SYSTEMD_LOG_LEVEL=debug test/udev-test.pl is working now
Also, fixes CID 1354602
|
|
All callers of create_symlink(), such as install_info_symlink_wants(), expect
that to return > 0 if it actually did something, and then return that number.
unit_file_enable() uses that to determine if any action was done
(carries_install_info != 0) and if not, show a "The unit files have no
[Install] section" warning.
Return 1 instead of 0 in the two code paths of create_symlink() when the link
was created or replaced with a new value.
This fixes getting a bogus "No [Install] section" warning when enabling a unit
with full path, like "systemctl enable /some/path/myunit.service".

nspawn: always setup machine id (v3)
|
|
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.

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.
|
|
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.

Add tags tests to udev-test.pl
|
|
Fix commit 1d88a2: We need to allocate another byte for building the "tags"
string, as we append an extra ':' and still need the NUL terminator.

* This reverts commit 646048b40a7b62c4e9bc59024ef6133613cda01b.
Let's test really big numbers again

As suggested https://github.com/systemd/systemd/pull/2966#issuecomment-205751680

nss-dns is also "tested". It should be almost always available,
and provides a reference for comparison.

Also parse watchdog config when creating the Uploader object.

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

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

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
