Curently, these two flags were implied by dissect_loop_device(), but
that's not right, because this means systemd-gpt-auto-generator will
dissect the root block device with these flags set and that's not
desirable: the generator should not cause the partition devices to be
created (we don't intend to use them right-away after all, but expect
udev to find/probe them first, and then mount them though .mount units).
And there's no point in opening the partition devices, since we do not
intend to mount them via fds either.
Hence, rework this: instead of implying the flags, specify them
explicitly.
While we are at it, let's also rename the flags to make them more
descriptive:
DISSECT_IMAGE_MANAGE_PARTITION_DEVICES becomes
DISSECT_IMAGE_ADD_PARTITION_DEVICES, since that's really all this does:
add the partition devices via BLKPG.
DISSECT_IMAGE_OPEN_PARTITION_DEVICES becomes
DISSECT_IMAGE_PIN_PARTITION_DEVICES, since we not only open the devices,
but keep the devices open continously (i.e. we "pin" them).
Also, drop the DISSECT_IMAGE_BLOCK_DEVICE combination flag, since it is
misleading, i.e. it suggests it was appropriate to specify on all
dissected blocking devices, but that's precisely not the case, see the
systemd-gpt-auto-generator case. My guess is that the confusion around
this was actually the cause for this bug we are addressing here.
Fixes: #25528
reset_terminal_fd sets certain minimum required terminal attributes
that systemd relies on.
One of those attributes is `ONLCR` which ensures that when a new line
is sent to the terminal, that the cursor not only moves to the next
line, but also moves to the very beginning of that line.
In order for `ONLCR` to work, the terminal needs to perform output
post-processing. That requires an additional attribute, `OPOST`,
which reset_terminal_fd currently fails to ensure is set.
In most cases `OPOST` (and `ONLCR` actually) are both set anyway, so
it's not an issue, but it could be a problem if, e.g., the terminal was
put in raw mode by a program and the program unexpectedly died before
restoring settings.
This commit ensures when `ONLCR` is set `OPOST` is set too, which is
the only thing that really makes sense to do.
Otherwise the `terminate()` method sends SIGKILL rather quickly (~0.3s),
which then leaves a dangling scope on the host system, breaking further
test executions.
If the cgroup is owned by root there is no need to get prefix_uid. Only
check prefix_uid when uid != 0, and then set MANAGED_OOM_PREFERENCE_NONE
and return early if uid != prefix_uid.
This is a wrapper around fd_reopen() that will reopen an fd if the
F_GETFL flags indicate this is necessary, and otherwise not.
This is useful for various utility calls that shall be able to operate
on O_PATH and without it, and might need to convert between the two
depending on what's passed in.
Currently the kernel-install man page only documents the bls layout for use
with the boot loader spec type #1. 90-loaderentry.install uses this layout to
generate loader entries and copy the kernel image and initrd to $BOOT.
This commit documents a second layout "uki" and adds 90-uki-copy.install,
which copies a UKI "uki.efi" from the staging area or any file with the .efi
extension given on the command line to
$BOOT/EFI/Linux/$ENTRY_TOKEN-$KERNEl_VERSION(+$TRIES).efi
This allows for both locally generated and distro-provided UKIs to be handled
by kernel-install.
