Whenever we're going to close all file descriptors, we tend to close
the log and set it into open when needed mode. When this is done with
the logging target set to LOG_TARGET_AUTO, we run into issues because
for every logging call, we'll check if stderr is connected to the
journal to determine where to send the logging message. This check
obviously stops working when we close stderr, so we settle the log
target before we do that so that we keep using the same logging
target even after stderr is closed.
Suppress errors when creating/writing EFI variables during 'bootctl update' if
'--graceful' mode is active (as the documentation indicates).
Closes#26773.
Let's allow configuring tty term and size using kernel cmdline arguments
so that when running in a VM we can communicate the terminal TERM and size
from the host via SMBIOS extra kernel cmdline arguments.
Useful in combination with CHASE_PARENT to get a directory file
descriptor to the parent directory of the resolved path and the
filename of the resolved path in the parent directory (which might
not be the same as the filename of the input path because of symlinks).
The nvme by-id symlink changes to the latest namespace when a new namespace gets
added, for example by connecting multiple NVMe/TCP host controllers via nvme
connect-all.
That is incorrect for persistent device links.
The persistent symbolic device link should continue to point to the same NVMe
namespace throughout the lifetime of the current boot.
Therefore the namespace id needs to be added to the link name.
Fix check for conflicting and duplicate expressions of types that
support alternative patterns.
Fixes: 3ec58d0cd8 ("udev-rules: check for conflicting and duplicate expressions")
For those token types that support matching of alternative patterns,
their token values are interpreted as nulstr, so make sure the parser
does the right thing and makes these token values terminated by two
subsequent NULs so they could be safely interpreted as nulstr.
Before this fix, the following rules would result to "echo foo" invocation:
ENV{foo}=", RUN"
ENV{foo}=="bar", RUN+="echo foo"
because the value of `ENV{foo}` is treated as nulstr, and it used to match
against alternative patterns, in this case `bar`, `, RUN`, and `="echo foo`.
Fixes: 25de7aa7b9 ("udev: modernize udev-rules.c")
For some unknown reasons, the temporary directory created by the test
below is not removed:
```
# Test the case that a valid symlink is in the path.
label = 'valid_symlink-deep'
test_content('f= {} - - - - ' + label, label, user=user, subpath='/deep/1/2', path_cb=valid_symlink)
```
To keep /tmp clean, let's create the global temprary directory.
