When the pool size limit is altered with "machinectl set-limit", then
not only set the subvolume quota of the /var/lib/machine subvolume, but
also resize the backing loop file and the btrfs file system on it
dynamically.
When running in user mode unmounting of mount units when a device
vanishes is unlikely to work, and even if it would work is already done
by PID 1 anyway. HEnce, when creating implicit dependencies between
mount units and their backing devices, created a Wants= type dependency
in --user mode, but leave a BindsTo= dependency in --system mode.
Commit 668c965af "journal: skipping of exhausted journal files is bad if
direction changed" fixed a correctness issue, but it also significantly
limited the cases where the optimization that skips exhausted journal
files could apply.
As a result, some journalctl queries are much slower in v219 than in v218.
(e.g. queries where a "--since" cutoff should have quickly eliminated
older journal files from consideration, but didn't.)
If already in the initial iteration find_location_with_matches() finds
no entry, the journal file's location is not updated. This is fine,
except that:
- We must update at least f->last_direction. The optimization relies on
it. Let's separate that from journal_file_save_location() and update
it immediately after the direction checks.
- The optimization was conditional on "f->current_offset > 0", but it
would always be 0 in this scenario. This check is unnecessary for the
optimization.
Add getrandom syscall numbers for MIPS. Based on Linux 3.17 kernel
(commit 42944521af97a3b25516f15f3149aec3779656dc, "MIPS: Wire up new
syscalls getrandom and memfd_create").
The build would fail later anyway, so it is better to bail
out early.
Also check for the second bios file only if the first one was not
found. I'm not sure which one is preferred. If the other one, the
order should be flipped.
gcc does not support testing for negated warnings. See here for details:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63499
This patch changes CC_CHECK_FLAG_APPEND to always test for the non-negated
warnings.
Many of machined's operations are now opened up to unprivileged clients
via PolicyKit. Open up the dbus policy so that we can actually make
these calls.
kdbus doesn't reuqire this, hence this wasn't noticed before.
When manipulating container and VM images we need efficient and atomic
directory snapshots and file copies, as well as disk quota. btrfs
provides this, legacy file systems do not. Hence, implicitly create a
loopback file system in /var/lib/machines.raw and mount it to
/var/lib/machines, if that directory is not on btrfs anyway.
This is done implicitly and transparently the first time the user
invokes "machinectl import-xyz".
This allows us to take benefit of btrfs features for container
management without actually having the rest of the system use btrfs.
The loopback is sized 500M initially. Patches to grow it dynamically are
to follow.
gcc5 spits out a warning about test-hashmap.c:

gcc5 introduced this option (gcc4 silently ignores it, which is fine).
Given that gcc5 thinks 'unsigned char'/'unsigned short' is promoted to
'int' for var-args, stuff like this spits out warnings:
uint8_t x;
printf("%" PRIu8", x);
gcc5 promots 'x' to 'int', instead of 'unsigned int' and thus gets a
signedness-warnings as it expects an 'unsigned int'.
glibc states otherwise: unsigneds are always promoted to 'unsigned int'.
Until gcc and glibc figure this out, lets just ignore that warning (which
is totally useless in its current form).
Commit 6e1bf7ab99 used the wrong directory; we need rootlibexecdir, not
rootlibdir, as the latter is something like /lib/x86_64-linux-gnu/ on
multi-arch systems.

The kernel part of kdbus does not allow userspace to make any assumption on
which unique address the first user on the bus will get.
Instead, use sd_bus_get_unique_name() to get the server's address.

Follow two small changes in the kdbus API:
* Flags are now returned in cmd->return_flags by KDBUS_CMD_NAME_ACQUIRE
* struct kdbus_item_list has been dropped. The information stored in
this struct was redundant since awhile already, as all commands
report their returned slice size anyway.
We would print the filename header before trying to open the file. But since
the header was printed to stdout, and the error to stderr, the error would appear
on the terminal before the header. It is cleaner to open the file first, then
and only then print the header.
Also exit on first error. We shouldn't report success if we were unable to open
a file.
This change exposed a bug in kernel headers:
/usr/include/linux/if_bridge.h:184:20: error: field 'ip6' has incomplete type
struct in6_addr ip6;
^
/usr/include/linux/if_tunnel.h:76:19: error: field 'prefix' has incomplete type
struct in6_addr prefix;

Include <sys/socket.h> from util.h and bus-message.h in order to
build errors like the ones below on kdbus enabled systems.

This patch removes includes that are not used. The removals were found with
include-what-you-use which checks if any of the symbols from a header is
in use.
