This is in preparation for later changes. The 1500+ line switch statement was very
hard to work with and had quite a bit of duplicated code. This is a rework that
splits outs parts into functions. I split this up into a bunch of commits so that it
can be reasonably reviewed. When viewed as one giant commit, diff just shows
a giant block of removed code and a giant block of added code.
In some cases I wasn't sure why one or the other of the identity arrays is used…
I preserved existing behaviour in all cases.
Currently, pick_filter_image_any matches any image
with any suffix, which is way more than it should
be doing. It should only be matching images with
the .raw suffix.
Let's address this shortcoming by allowing to pass
multiple filters to path_pick(), and define
pick_filter_image_any as the combination of the
raw and directory image filters.
Fixes#40083
Allow configuring the menu timeout used by sd-boot by setting
`io.systemd.boot.timeout=<value>` as SMBIOS type 11 string.
This takes precedence over the setting from the config file
and the EFI var.
Useful for e.g. integration tests that want to control that
a generic image boots faster.
When employing MCL_FUTURE we don't actually want it to impose
immediate population of malloc()-ed pages. Hence let's set
MCL_ONFAULT everywhere.
Additionally, specify MCL_CURRENT to ensure future memory allocations
on already mapped pages are covered too. (Addresses
https://github.com/systemd/systemd/pull/40319#discussion_r2693726196)
Note that in shutdown the mlockall() is done to avoid keeping swap space
busy, hence a dedicated call w/ MCL_CURRENT and w/o MCL_ONFAULT is made.
If no real jobs were added to the transaction, do not activate it.
The JOB_NOP anchor does not perform any useful work and activating
such transaction only wastes resources.
Fixes#9751
The systemd-vmspawn man page has a note that the `--notify-ready`
defaults to "true" and then says that this is unlike "systemd-vmspawn"
where it defaults to "false". This appears to be a copy/paste issue
and here we want "unlike systemd-nspawn".
We parse RLIMIT_FOO, FOO, and LimitFOO all the same. But the keys in the
JSON dict are supposed to be "RLIMIT_FOO". We were creating such keys,
but then filtering them using "FOO", i.e. the filtering was not effective.
Using strjoina since both strings are under our control.
Move the BPF_JMP_A macro from override/linux/bpf.h to
override/linux/bpf_insn.h. The bpf.h override conflicts with libbpf's
-I/usr/include/bpf/uapi include path. Since bpf_insn.h is not typically
installed at /usr/include/linux/ or /usr/include/bpf/uapi/linux/, the
override works without conflicts.
Fixes#40331
