Lennart Poettering 5a44565cb7 gpt: we actually honour the ReadOnly= flag on XBOOTLDR partitions too 
The partition type is defined in our Discoverable Partition Spec, and we
honour the flag for it, hence allow setting it too.

Igor Zhbanov 4c54768c97 journald: Retry if posix_fallocate returned -1 (EINTR) 
On some conditions (particularly when mobile CPUs are going to sleep),
the posix_fallocate(), which is called when a new journal file is allocated,
can return -1 (EINTR). This is counted as a fatal error. So the journald
closes both old and journals, and simply throwing away further incoming
events, because of no log files open.

Introduce posix_fallocate_loop() that restarts the function in the case
of EINTR. Also let's make code base more uniform by returning negative
values on error.

Fix assert in test-sigbus.c that incorrectly counted positive values as
success. After changing the function return values, that will actually work.

Fixes: #19041

Lennart Poettering 2b66f48e4e generator: write out special systemd-fsck-usr.service 
So far all file systems where checked by instances of
systemd-fsck@.service, with the exception of the root fs which was
covered by systemd-fsck-root.service. The special handling is necessary
to deal with ordering issues: we typically want the root fs to be
checked before all others, and — weirdly — allow mounting it before the
fsck done (for compat with initrd-less boots).

This adds similar special handling for /usr: if the hierarchy is placed
on a separate file system check it with a special
systemd-fsck-usr.service instead of a regular sysemd-fsck@.service
instance. Reason is again ordering: we want to allow mounting of /usr
without the root fs already being around in the initrd, to cover for
cases where the root fs is created on first boot and thus cannot be
mounted/checked before /usr.

Zbigniew Jędrzejewski-Szmek 580f48cc02 partition,shared/gpt: use sd_id128_in_set() 
I was worried that the text size will grow, but apparently that's not the
case:
With --optimization=2:
$ size build/src/shared/libsystemd-shared-248.a.p/gpt.c.o*
   text	   data	    bss	    dec	    hex	filename

   3085	   1104	      0	   4189	   105d	build/src/shared/libsystemd-shared-248.a.p/gpt.c.o

(I don't understand the generated assembly, even though it seems to work:

Zbigniew Jędrzejewski-Szmek 64b21afc72 sd-id128: add convenience functions to compare multiple sd_id128_t 
Similar to sd_bus_error_has_names() that was added in
2b07ec316a.

It is made inline in the hope that the compiler will be able to optimize
all the va_args boilerplate away, and do an efficient comparison when
the arguments are all constants.

Lennart Poettering 599aee40a3 generator: explain why systemd-root-fsck.service exists in a comment 2021-04-21 15:18:07 +02:00
Lennart Poettering 122860f102 generator: exit early when asked to generate fsck unit for / and /usr in initrd 
Let's exit early if we are invoked to generate an fsck unit for the
rootfs or /usr of the initrd itself. The "systemd-root-fsck.service" and
"systemd-usr-fsck.service" units are after all for the host file
systems, and the initrd file hierarchy is from an unpacked cpio anyway.
Hence, this semantically doesn't really make sense, so quickly exit if
we detect this case. This allows us to remove some checks further down
the codepath.
