We know how the field we are parsing is called, let's put this information in
the error message:
"Route Source= prefix is invalid, ignoring assignment: ..."
"Route Destination= prefix is invalid, ignoring assignment: ..."
We counted how many filesystems could not be unmounted, but only for those
filesystems which we tried to unmount. Since we only remount / ro, without
attempting to unmount, we would emit a confusing error message:
Remounting '/' read-only with options 'seclabel,space_cache,subvolid=5,subvol=/'.
Remounting '/' read-only with options 'seclabel,space_cache,subvolid=5,subvol=/'.
Remounting '/' read-only with options 'seclabel,space_cache,subvolid=5,subvol=/'.
All filesystems unmounted.
Warn when remount-ro fails, and for filesystems which we won't try to unmount,
include the failure to remount-ro in n_failed.
A few minor cleanups:
- remove unecessary goto which jumps to the next line anyway
- always calculate n_failed, even if log_error is false. This causes no change
in behaviour, but I think the code is easier to follow, since the log setting
cannot influence other logic.

busctl: monitor - only start printing messages once we have become a monitor (#5931)
A connection becomes a monitor the moment it loses its unique name, so any
messages received before that should not be dumped to the console.
Currently, we print NameAcquired and NameLost for the unique name of the
peer that becomes the monitor, simply discard all messages until we
receive our NameLost signal.
seccomp: enable RestrictAddressFamilies on ppc64, autodetect SECCOMP_RESTRICT_ADDRESS_FAMILIES_BROKEN
We expect that if socket() syscall is available, seccomp works for that
architecture. So instead of explicitly listing all architectures where we know
it is not available, just assume it is broken if the number is not defined.
This should have the same effect, except that other architectures where it is
also broken will pass tests without further changes. (Architectures where the
filter should work, but does not work because of missing entries in
seccomp-util.c, will still fail.)
i386, s390, s390x are the exception — setting the filter fails, even though
socket() is available, so it needs to be special-cased
(https://github.com/systemd/systemd/issues/5215#issuecomment-277241488).
This remove the last define in seccomp-util.h that was only used in test-seccomp.c. Porting
the seccomp filter to new architectures should be simpler because now only two places need
to be modified.
RestrictAddressFamilies seems to work on ppc64[bl]e, so enable it (the tests pass).

automount: ack automount requests even when already mounted (#5916)
If a process accesses an autofs filesystem while systemd is in the
middle of starting the mount unit on top of it, it is possible for the
autofs_ptype_missing_direct request from the kernel to be received after
the mount unit has been fully started:
systemd forks and execs mount ...
... access autofs, blocks
mount exits ...
systemd receives SIGCHLD ...
... kernel sends request
systemd receives request ...
systemd needs to respond to this request, otherwise the kernel will
continue to block access to the mount point.
50-udev-default.rules.in: set correct group for mediaX/cecX (#5921)
The /dev/mediaX and /dev/cecX devices belong to the video group.
Add two default rules for that.
The /dev/cecX devices were introduced in kernel 4.8 in staging and moved
out of staging in 4.10. These devices support the HDMI CEC bus.
The /dev/mediaX devices are much older, but because they are not used very
frequently nobody got around to adding this rule to systemd. They let the
user control complex media pipelines.
Adds support for booting in a SecureBoot environment with shim as a
preloader. Install an appropriate UEFI security policy to check PE
signature of a chained kernel or UEFI application (using LoadImage())
against the MOK database maintained by shim, using shim's installed
BootServices.
Implementation details for installing the security policy are based on
code from the LinuxFoundation's SecureBoot PreLoader, part of efitools
licensed under LGPL 2.1
Current signed (by Microsoft) versions of shim (Versions 0.8 & 0.9)
so not install a security policy by themselves, future Versions of
shim might (a compile time switch exists in rectent git versions),
so in the future this PR might become unnecessary.
Since all our python scripts have a proper python3 shebang, there is no benefit
to letting meson autodetect them. On linux, meson will just uses exec(), so the
shebang is used anyway. The only difference should be in how meson reports the
script and that the detection won't fail for (most likely misconfigured)
non-UTF8 locales.
seccomp: assume clone() arg order is known on all architectures
While adding the defines for arm, I realized that we have pretty much all
known architectures covered, so SECCOMP_RESTRICT_NAMESPACES_BROKEN is not
necessary anymore. clone(2) is adamant that the order of the first two
arguments is only reversed on s390/s390x. So let's simplify things and remove
the #if.
seccomp: drop SECCOMP_MEMORY_DENY_WRITE_EXECUTE_BROKEN, add test for shmat
SECCOMP_MEMORY_DENY_WRITE_EXECUTE_BROKEN was conflating two separate things:
1. whether shmat/shmdt/shmget can be filtered (if ipc multiplexer is used, they can not)
2. whether we know this for the current architecture
For i386, shmat is implemented as ipc, so seccomp filter is "broken" for shmat,
but not for mmap, and SECCOMP_MEMORY_DENY_WRITE_EXECUTE_BROKEN cannot be used
to cover both cases. The define was only used for tests — not in the implementation
in seccomp-util.c. So let's get rid of SECCOMP_MEMORY_DENY_WRITE_EXECUTE_BROKEN
and encode the right condition directly in tests.
meson: use booleans for conf.set and drop unecessary conditionals
Using conf.set() with a boolean argument does the right thing:
either #ifdef or #undef. This means that conf.set can be used unconditionally.
Previously I used '1' as the placeholder value, and that needs to be changed to
'true' for consistency (under meson 1 cannot be used in boolean context). All
checks need to be adjusted.
This is similar to what ./configure prints. Instead of a long list of yes/no lines,
I added two lines at the end with "enabled features" and "disabled features".
This is what the mplayer/mencoder ./configure script did back in the day.
The advantage is that it's easy to look at the list of disabled features
and check for any unexpected entries.

build-sys: re-add systemd.directives and systemd.index to MANPAGES (#5876)
Those were dropped accidentally in commit 19fe49f62cc916f1237ea92a04fc80ee75285dde, most likely by running
make update-man-list. This is a known limitation of the autotools build:
the man pages must be built before update-man-list is called.
meson: make sure html symlinks are also created in build directory
The symlinks should be created in the build directory in two cases: when
configuration specifies -Dhtml=true, or when ninja html target is built.
Normally install : {true,false} is used to decide if a target should be built,
but in this case, we cannot use install : true, because, as described in 488477d101, that results in the target file being copied into the
installation directory instead of a symlink. So we need a work-around. To
achieve the first end, the commands to create the symlinks are added as
dependencies of the command to create the html page. To the second end, they
are added as dependencies of the html target.
This adds two somewhat independent rules:
1. to create symlinks to html pages in the build directory
2. to create symlinks in the installation directory
The second part needs to be coded separately, because telling meson to install
the symlinks created in step 1. results in a copy of the target, instead of a
symlink. So step 2. needs to ignore the result of 1. and create the symlink again.

networkd: Add check to ensure link is down before attempting to enslave (#5853)
netdev to bond.
There are situations where a link can be in an "UP" state when
systemd-networkd attempts to add the link to a bond device.
This is a problem because the bonding driver will refuse to
enslave a link if it is in the "UP" state.
This check ensures systemd-networkd sets the link to "DOWN"
before attempting to add the link to the bond.

meson: do not link libshared dynamically against libudev (#5850)
Linking dynamically against libudev will fail once

Make libshared provide the udev symbols by including libudev_sources
into libshared. This will cause those files to be compiled twice, but it
actually reduces the installed size and is closer to what the autotools
build system is doing.
