The device node may be different from we want to activate, and we may
try to activate different device in the subsequent loop. In such case,
we should enable the automatic removal for the unexpected device.
Otherwise, it will not be removed even when not necessary anymore.
Both sleep_mode_supported and write_mode support this,
but parse_sleep_config currently prohibits this - it always
uses our default value if user specifies HibernateMode=<empty>.
We use it for more than just pipe() arrays. For example also for
socketpair(). Hence let's give it a generic name.
Also add EBADF_TRIPLET to mirror this for things like
stdin/stdout/stderr arrays, which we use a bunch of times.
This restores display of the "delegate" flag of a cgroup. Previously we
erroneously passed a full fs path where a cgroup path was expected (the
difference being the /sys/fs/cgroup/ prefix), which meant we never read
the xattr properly. Let's fix that by simply operating by fd on the
cgroup and using it for all operations.
If user requests hybrid sleep, we should always use 'suspend'
disk mode. If that's not supported, let's correctly report it
so they can choose plain hibernation instead. HybridSleepMode=
serves no purpose in this case and should be removed.

This is like --cat-config, but omits the comments and empty lines.
The name is incoungrous with --cat-config, but I don't see a nice way to
call it that wouldn't be annoyingly long.
pager_open() is moved to cat_config() to remove some lines from run().
When looking at configuration, often a user wants to suppress the comments and
just look at the parts that actually configure something, roughly equivalent to
systemd-analyze cat-config … | rg -v '^(#|;|$)
This switch implements this natively, skipping lines that start with a comment
character or only contain whitespace.
For formats that have section headers, section headers are skipped, if only
followed by stuff that would be skipped. (The last section header is printed
when we're about to print some actual output.)
Note that the caller doesn't know if the format has headers or not. We do format
type detection in pretty-print.c. So the caller only specifies tldr=true|false, and
conf_files_cat() figures out if the format has headers and whether those should
be handled specially.
The comments that show the file name are always printed, even if all of the file
is suppressed.
This is a partial answer to the discussions in
https://github.com/systemd/systemd/pull/28919,
https://github.com/systemd/systemd/pull/29248. If the default config is shown in
config files, the user can conveniently use '--tldr' to show the relevant parts.
This seems to be the only place where rm_rf_children() is called with a
possibly used fd, which is then passed through to rm_rf_children_impl().
This also fixes#29606.
(Tested on Fedora rawhide with kernel 6.5.6-300.fc39.x86_64.)
SuspendState= not to include "disk"
I don't know why these existed in the first place, but as I
justified in the comments, it's simply not sensible to allow
HibernateState= or HybridSleepState= to take values other than
'disk'. So let's just remove those options. Also, SuspendState=
should not contain 'disk'.
This reverts commit 6bbb893b90.
Let's try a different approach where we make sure that all callers only pass in
a fd that is "clean", i.e. at offset 0. The majority of callers of this function
(both direct and indirect) pass a freshly-opened fd, so the rewind call is not
needed.
Let's split out the logic that actually generates the word to measure to
PCRs into a new helper file pcrextend-util.[ch].
This we can later reuse to calculate PCR measurement predictions ahead
of time.
These are not used outside of tpm2-util.[ch], and the way they merge
public/private key pair into one blob is kinda specific to our
implementation, hence better should be hidden away, and not used for new
code anyway.
We'll soon have a function for determining the name of an NV index,
hence let's rename the existing function for the same of a public key to
make clear it's about public keys only.
After 7470b80763, we refuse
to hibernate if we fail to write HibernateLocation EFI
variable and resume= is not set. Let's teach sleep_supported
to follow the practice too.
* "HibernateLocation" struct is renamed to HibernationDevice
to avoid ambiguity with the EFI variable. Also, it no longer
takes the reference to a SwapEntry object, since it's really
unnecessary (only SwapEntry.path is used), but increases complexity.
* SwapEntry is no longer used externally.
* find_hibernate_location is split into read_swap_entries and
find_suitable_hibernation_device. The former reads all swap entries
into SwapEntries object for later use.
* Make use of btrfs_get_file_physical_offset_fd
Closes#25130
mcopy will set the modification time of created directories to the mtime
of the source directories but converts it to the timezone of the host.
This behavior is identical to Windows / DOS:
> The FAT file system stores time values based on the local time of the computer.
-- https://learn.microsoft.com/en-us/windows/win32/sysinfo/file-times
To achieve reproducible builds, mcopy should be invoked with TZ=UTC.
