76ec966f0e changed the code from ESHUTDOWN to ERFKILL, but missed one
spot in bus-common-errors.c. Fix that.
The code in transaction.c was checking for ERFKILL, but I'm not sure if this
mismatch had any effect, i.e. if there were any code paths in which the wrong
code actually made difference.
Also add comments when ESHUTDOWN is used in the journal code, so it's easy to
distinguish those cases when grepping. Standarize on the same capitalization.
(There's also a bunch of uses in sd-bus.c, but that's clearly different.)
The failure message is typically currently:
execv() failed: No such file or directory
which is not very useful because it doesn’t tell you which file or
directory it was trying to exec.
networkd: Allow ':' in label
This reverts a341dfe563 and takes a slightly different approach: anything is
allowed in network interface labels, but network interface names are verified
as before (i.e. amongst other things, no colons are allowed there).
src/nss-resolve/nss-resolve.c: In function ‘_nss_resolve_gethostbyname_r’:
src/nss-resolve/nss-resolve.c:680:13: warning: RES_USE_INET6 is deprecated
NSS_GETHOSTBYNAME_FALLBACKS(resolve);
^~~~~~~~~~~~~~~~~~~~~~~~~
In glibc bz #19582, RES_USE_INET6 was deprecated. This might make sense for
clients, but they didn't take into account nss module implementations which
*must* continue to support the option. glibc internally defines
DEPRECATED_RES_USE_INET6 which can be used without emitting a warning, but
it's not exported publicly. Let's do the same, and just copy the definition
to our header.
gcc 7 adds -Wimplicit-fallthrough=3 to -Wextra. There are a few ways
we could deal with that. After we take into account the need to stay compatible
with older versions of the compiler (and other compilers), I don't think adding
__attribute__((fallthrough)), even as a macro, is worth the trouble. It sticks
out too much, a comment is just as good. But gcc has some very specific
requiremnts how the comment should look. Adjust it the specific form that it
likes. I don't think the extra stuff we had in those comments was adding much
value.
(Note: the documentation seems to be wrong, and seems to describe a different
pattern from the one that is actually used. I guess either the docs or the code
will have to change before gcc 7 is finalized.)
```
-bash-4.3# systemd-run --property BindPaths=/etc:tmp/hey sh -c 'ls /tmp/hey'
```
prints
`Destination path tmp/hey is not absolute.`
instead of
`Destination path /etc is not absolute.`
CID #1368239
If chase_symlinks() encouters an absolute symlink, it resets the todo
buffer to just the newly discovered symlink and discards any of the
remaining previous symlink path. Regardless of whether or not the
symlink is absolute or relative, we need to preserve the remainder of
the path that has not yet been resolved.
When the service is run in the initramfs, it is possible for it to get started
and not be fast enough to exit before the root switch happens. It is started
multiple times (depending on the consoles being detected), and runs
asynchronously, so this is quite likely. It'll then get killed by killall(),
and systemd will consider the service failed. To avoid all this, just wait
for the service to terminate on it's own.
Before=initrd-switch-root.target should be good for the initramfs, and
Before=shutdown.tuarget should be good for the real system, although it's
unlikely to make any difference there.
The service already has DefaultDeps disabled, so systemd should not try to stop
it. And if it *does* get stopped, we don't want the zombie process around.
KillMode=none does not change anything in the killall() phase, and we already
use argv[0][0] = '@' to protect against that anyway. KillMode=none should not
be useful in normal operation, so let's leave it out.
Instead of using a temp buffer to replace whitespace in variable
substitutions, just allow util_replace_whitespace to replace in-place.
Add a comment to util_replace_whitespace indicating it is used to replace
in-place, to prevent accidental future breakage.
allow _journalctl to work when the rcquotes option is set, broken in ba89f80620.
allow the completion of --file multiple times, which ba89f80620 claims is true.
Fixes#4842
add udev-test.pl tests for whitespace in a substituted variable,
to verify the variable whitespace is replaced with underscores.
Tests for the change made by commit 0a10235ed4 ("udev-rules:
perform whitespace replacement for symlink subst values")
Fixes:
```sh
systemd-run --property EnvironmentFile=/some/environment/file /bin/sleep 30
```

Closes: #5142
When an alias is loaded, we resolve this alias to its final unit first to load
the dropin data.
However if the final unit was already loaded, there's no point in reloading the
dropin data a second time.
This patch optimizes this case.
Also this allows the dropin loading code to assume that only units not yet
loaded are passed down. This assumption is not yet used but might be in the
future.
