This function is just a wrapper around the BLKGETSIZE64. Which is a
pretty simple ioctl. The only reason to wrap it, is that the headers we
need to call it are a bit messy (as "linux/fs.h" is incompatible with
certain glibc headers). Hence add the simple helper that wraps it and
allows us to do the header mess needed in one file only.
It's also nicely symmetric to blockdev_get_sector_size().
* Use a unified struct to store accounting fields/suffixes
* Use strextendf_with_separator where appropriate
* Don't mix stack and heap allocation for one iovec array
THis brings the list of attributes to delegate to managers of subcgroups
to the state of kernel 6.6.
We probably should unify this list, and maybe generate it automatically
from /sys/kernel/cgroup/delegate, but let's do that another time.
The reference implementation seems to set the 'parameters' field for
method calls to 'null' if nothing is specified on its command line. We
so far only could deal if the parameters field was unset or set to the
empty object. Let's also accept the 'null' type.
When /boot or friends is on btrfs RAID, btrfs_get_block_device_at() will
succeed with 0 and provide zero devnum. Then,
- if we are previleged, devname_from_devnum() maps the devnum to
/run/systemd/inaccessible/blk, and the subsequent verification by blkid
will fail,
- if we are unprevileged, sd_device_new_from_devnum() will fail.
This makes
- when find_esp() or find_xbootldr() is called without any paths, that
is, called with the searching mode, then returns -ENOKEY, which should
be handled gracefully by the caller,
- when they are called with an input path, then they provide the proper
error message and suggestion.
Fixes RHBZ#2251262 (https://bugzilla.redhat.com/show_bug.cgi?id=2251262).
The image name is extracted from the image path originally passed in,
i.e. not the contents of the image. And the image UUID is directly
retrieved from the partition table, hence also not from the contents.
Let's hence move the comment to separate out the stuff extract from the
file systems (and thus only available when mounting/with privs/with
block devices) from the data available without any of that.
This is the common case in --user instances, hence handle this
gracefully.
This should be safe since user instances won't get access to
/dev/console-related ttys anyway, but only their own ptys.
The original version would yield a slightly _unexpected_ message for
this [Address] section:
[Address]
Address=10.9.3.1/24
HomeAddress=yes
ManageTemporaryAddress=yes
systemd-networkd[68396]: /run/systemd/network/25-address-static.network: unexpected address flags "n/a" were configured. Ignoring [Address] section from line 144.
Let's instead show the unexpected flags:
systemd-networkd[69160]: /run/systemd/network/25-address-static.network: unexpected address flags "home-address,manage-temporary-address" were configured. Ignoring [Address] section from line 144.
Currently, start/stop messages for device units are not used, since
job_perform_on_unit() does nothing and we simply wait for unit status
change. I think we still want some nice log messages explaining what
the start jobs for devices are doing, so let's fix this.
Just use ExecParam directly, as these are all internal to sd-exec now
anyway. Avoids double close when execution fails after FDs are set up
for inheritance and were already re-arranged.
