If we don't have ifindex info, don't set the field for it.
We already do that for parsed IP address replies, let's do it for all
cases: it's a bit nicer to suppress the ifindex prop if it doesn't apply
than to pass it invalid.
This is the other side of #18482, i.e. fixes things so that the parser
doesn't get tripped up by this.
(This too makes a problem go away we should track down properly, i.e.
figure out how the ifindex got lost in
https://github.com/systemd/systemd/pull/17823#issuecomment-742439422 )
Aaargh. See the comment in the code.
Apparently the range is like that:
$ sudo bash -c 'echo "default 1001" >/sys/fs/cgroup/user.slice/io.bfq.weight'
bash: line 0: echo: write error: Numerical result out of range
$ uname -r
5.11.0-0.rc4.129.fc34.x86_64
Instead of using a short fixed string, let's use a huge blob for
testing, with randomized size and contents, that definitely is above the
16K buffer size conservative_renameat() uses internally.
The "XDG standardization for applications" specification states that
services should be in the form:
app[-<launcher>]-<ApplicationID>[@<RANDOM>].service or
app[-<launcher>]-<ApplicationID>-<RANDOM>.scope
In this case "autostart" takes the place of [RANDOM] to provide a unique
identifier if the same app is launched elsewhere. As it is a service
that means it should be set as a template not using a hyphen delimiter.
To add secure-boot enrolling support, we need to be able to specify
the EFI_VARIABLE_APPEND_WRITE flag so let's make the efivar_set()
methods more generic so we can set that flag.
Let's make sure we still look at the etags reported by http 304 (i.e.
the cache management code). Otherwise we won't properly realize we
already downloaded this before.
This fixes a bug introduced in 6792cbbcf8
