Then, all nexthops managed by networkd really exist (unless the kernel
silently removes a nexthop).
This is the same for nexthop already done by
3c283289ae and
0a0c2672db (for address), and
5d098f5d36 (for neighbor).
The kernel manages nexthops by their IDs. Previously networkd manages
nexthops in three ways:
- by the corresponding link, if a nexthop has ifindex,
- by the manager, if a nexthop does not have ifindex,
- by the manager with their IDs.
This unifies the three managements of nexthops into one, and use the
same way as the kernel uses.
This is the one for nexthop already done by
aa9626ee3b for neighbor.
If a nexthop is requested without a valid ID, then nexthop_acquire_id()
assigns an unused ID. So, at the time nexthop_configure() is called, the
ID is always valid.
Same as $KERNEL_INSTALL_BYPASS, but for hwdb. This will speed up
cross architecture image builds in mkosi as I can disable package
managers from running the costly hwdb update stuff in qemu user
mode and run it myself with a native systemd-hwdb with --root=.
This is gets the resource limits off a specified process, and is very
similar to prlimit() with a NULL new_rlimit argument. In fact, it tries
that first. However, it then falls back to use /proc/$PID/limits. Why?
Simply because Linux prohibits access to prlimit() for processes with a
different UID, but /proc/$PID/limits still works.
This is preparation to allow nspawn to run unprivileged.
It's pointless showing info that isn#t going to survive the current
invocation, hence hide it.
The "partition number" column is more useful since it kinda shows the
same information, but without the device node name prefixed that is
local to the currentl invocation.
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.
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.
