unmount: Pass in mount options when remounting read-only
man 2 mount says that the mountflags and data parameteres should
match the original values except for the desired changes. We only
bother with the mount options since the only flags we can change
are MS_RDONLY, MS_SYNCHRONOUS and MS_MANDLOCK; which shouldn't
matter too much.
We usually avoid relying on C's degrade-to-boolean functionality when
comparing numerical variables with 0. We use it only for pointers and
actual booleans.
util: remove lookup_uid(), replace by uid_to_name()
So far we had two pretty much identical calls in user-util.[ch]:
lookup_uid() and uid_to_name(). Get rid of the former, in favour of the
latter, and while we are at it, rewrite it, to use getpwuid_r()
correctly, inside an allocation loop, as POSIX intended.
sd-*.h: clean up exported (or to-be-exported) header files
Exported header files should not include internal headers. Fix that.
Exported header files should not use the bool type. So far we opted to
stick to C89 for exported headers, and hence use "int" for bools in
them. Continue to do so.
Exported header files should have #include lines for everything they use
including inttypes.h and sys/types.h, so that they may be included in
any order.
Exported header files should have C++ guards, hence add them.
Exported header files should not use gcc extensions like #pragma once,
get rid of it.
Technically, it's safer that way, since dnf is supposed to parse the
"*", not the shell. It doesn't really matter too much in real life (as
the expression is too complex), but let's better be safe than sorry, and
make sure people won't file bugs about this...
util-lib: split our string related calls from util.[ch] into its own file string-util.[ch]
There are more than enough calls doing string manipulations to deserve
its own files, hence do something about it.
This patch also sorts the #include blocks of all files that needed to be
updated, according to the sorting suggestions from CODING_STYLE. Since
pretty much every file needs our string manipulation functions this
effectively means that most files have sorted #include blocks now.
util-lib: get_current_dir_name() can return errors other than ENOMEM
get_current_dir_name() can return a variety of errors, not just ENOMEM,
hence don't blindly turn its errors to ENOMEM, but return correct errors
in path_make_absolute_cwd().
This trickles down into a couple of other functions, some of which
receive unrelated minor fixes too with this commit.
path-util: rework find_binary(), fsck_exists() and mkfs_exists()
Modernize the code a bit:
- Get rid of FOREACH_WORD_SEPARATOR() loop in favour of a
extract_first_word() loop.
- Remove find_binary()'s "local" flag. It's not reasonably possible to
look for binaries on remote systems, we hence should not pretend we
could.
- When we cannot find a suitable binary, return the last error returned
from access() rather than ENOENT unconditionally.
- Rework fsck_exists() and mkfs_exists() to return 1 on success, 0 if
the implementation is missing and negative on real errors. This is
more like we do it in other functions.
- Make sure we also detect direct fsck symlinks to "true", rather than
just absolute ones to /bin/true.

units: add 'SmackFileSystemRoot=*' option into tmp.mount
If SMACK is enabled, 'smackfsroot=*' option should be specified when
/tmp is mounted since many non-root processes use /tmp for temporary
usage. If not, /tmp is labeled as '_' and smack denial occurs when
writing.
In order to do that, 'SmackFileSystemRoot=*' is newly added into
tmp.mount.

mount: add new SmackFileSystemRoot= setting for mount unit
This option specifies the label to assign the root of the file system if
it lacks the Smack extended attribute. Note that this option will be
ignored if kernel does not support the Smack feature by runtime
checking.
test-compress-benchmark: limit default runtime to 2 seconds per subtest
If both lz4 and xz are enabled, this results in a limit of
2×3×2 s ~= 12 s runtime.
Previous implementation started with really small buffer sizes. When
combined with a short time limit this resulteded in abysmal results for xz.
It seems that the initialization overead is really significant for small
buffers. Since xz will not be used by default anymore, this does not
seem worth fixing. Instead buffer sizes are changed to run a
pseudo-random non-repeating pattern. This should allow reasonable testing
for all buffer sizes. For testing, both runtime and the buffer size seed
can be specified on the command line. Sufficiently large runtime allows
all buffer sizes up to 1MB to be tested.
util: Replace state with separate booleans in extract_first_word
This simplifies the logic and uniformizes the way single and double
quotes are handled. In the end, the code is about 40 lines shorter.
Tested by running the excellent test cases from test-util. Also
installed the systemd binaries including this patch and booted a
system with it, everything looked normal.
man: also add --enablerepo=updates to dnf invocation
Without the updates repo, we are installing packages from the time
that that version of Fedora was released. Normally, during the
lifetime of the release most packages are updated, so most of the
packages installed would be outdated, and the first update after
installation would update a massive set of packages. Avoid all this
by installing from the updates repo from the start.
Keys for previous and future Fedora distributions were added
for the fedora-repos package recently:
https://bugzilla.redhat.com/show_bug.cgi?id=1246701.
There is no need to skip signature checking.
Also, update to the latest and greatest and remove unnecessary quotes.

sd-ndisc: don't trigger timeout on prefix expiry
The caller of the library is no longer notified, so triggering a timer
just to clean up is not necessary. Instead check for and clean up
invalid prefixes lazily.

networkd: dhcp6 - do not handle prefix expiration
This ressurects 47d45d3cde45d6545367570264e4e3636bc9e345. We now always use /128 prefixes,
so there is no need for the DHCPv6 code to know about prefixes expiring.

sd-icmp6-nd: rename files to sd-ndisc
The actual code rename will follow. The reason for the change of name is to make it
simpler and more uniform with how we name other libraries (we don't include the
underlying protocol). The new name also matches the naming in the kernel (which
is particularly relevent here as we expect to let the kernel do some parts of
the protocol and we do others).
