missing.h: Explicitly check for IFLA_BRPORT_PROXYARP
RHEL explicitly disables IFLA_BRPORT_PROXYARP by renaming the enum value.
In order to support unpatched builds, we have two options:
a) redefine the enum value through missing.h and ignore the fact that it
is really unsupported, or
b) omit that enum value on rtnl_prot_info_bridge_port_types[]
As we are not actually using this netlink type anywhere, and because it
is only hooked up for the sake of completeness, this patch opts for the
former.
udev-rules: make error messages about rules more uniform
Also downgrade non-fatal warnings to log_warning.
Previously rule_add_key() would check the output array and log a cryptic
error and return -1. Most of the time the return value was ignored. This
does not seems right, because the buffer can overflow with enough rules.
It would also check if we have enough space for the *next* rule, even if
there might be not next rule, i.e. off-by-one.
Replace this with a check that we have enough space for a next rule before
we start parsing.
Normally using macros to alter flow is not allowed, but in this case I
think it is worth it, because it allows lots of boilerplate code to be
removed and hides repeated boring parameters, making function logic much
easier to follow.
test-siphash24: add a test for concatenating very short buffers
coverity seems to think that our siphash code can read past the
end of a short buffer. Add a test which adds very short buffers
with different combinations of length to the hash. Hashing is done
twice, once with zeros following "data", and once with some other
bytes following "data". The two results are then compared to
verify that the result does not depend on bytes past the specified
data length.

journal: defer journal closes on rotate
When we rotate journals, we must set offline and close the current one,
but don't generally need to wait for this to complete.
Instead, we'll initiate an asynchronous offline via
journal_file_set_offline(oldfile, false), and add the file to a
per-server set of deferred closes to be closed later when they
won't block.
There's one complication however; journal_file_open() via
journal_file_verify_header() assumes that any writable journal in the
online state is the product of an unclean shutdown or other form of
corruption.
Thus there's a need for journal_file_open() to be aware of deferred
closes and synchronize with their completion when opening preexisting
journals for writing. To facilitate this the deferred closes set is
supplied to the journal_file_open() function where the deferred closes
may be closed synchronously before verifying the header in such
circumstances.

journal: asynchronous journal_file_set_offline()
This adds a wait flag to journal_file_set_offline(), when false the offline is
performed asynchronously in a separate thread.
When wait is true, if an asynchronous offline is already in-progress it is
restarted and waited for. Otherwise the offline is performed synchronously
without the use of a thread.
journal_file_set_online() cancels or waits for the asynchronous offline to
complete if in-flight, depending on where in the offline process the thread
happens to be. If the thread is in the fsync() phase, it is cancelled and
waiting is unnecessary. Otherwise, the thread is joined before proceeding.
A new offline_state member is added to JournalFile which is used via
atomic operations for communicating between the offline thread and the
journal_file_set_{offline,online}() functions.
test-hashmap: fix undefined behaviour on string constants
The test was failing at -O2+ with gcc 5.3 and 6.0.
"val1" == "val1" and "val1" != "val1" are both valid.
http://stackoverflow.com/questions/4843640/why-is-a-a-in-c
Various buffers were lost because finish_item() either consumed
the buffer or allocated a new one (if an entry with the same key existed).
The caller would simply forget the buffer in either case.
Also add a check for the case when a valid identifier is followed by
an empty body. We should not allow this.
Also be more consistent in error handling and always print an error
message.
This patch contains a set of little cleanups for alloc-util.h:
1. The malloc_multiply(), realloc_multiply() and memdup_multiply()
functions check allocation related parameters on overflow. Let's
move them to the separate size_multiply_overflow() function for
simplicity, code duplication prevention and possible reuse in future.
2. use SIZE_MAX from stdlib instead of ((size_t) - 1) to be more
clear.
3. The 'a'/'b' variables are renamed to 'size' and 'need' to be
more clear.'

build-sys: Do not build tests that depend on resolved when it has been disabled
If ./configure --disable-resolved has been used, do not try to build
test-dns-packet and test-resolve-tables which depend on it.
Previously, the SOURCES, LIBS and LDADDs for these tests were made conditional
while the main rules for them weren't, causing build failures trying to build a
binary with no sources.
This was uncovered when trying to build udeb for systemd in CI, which uses
--disable-resolved for a minimal build, which uncovered the issue.
When the buffer is allocated on the stack we do not have to check for
failure everywhere. This is especially useful in debug statements, because
we can put dns_resource_key_to_string() call in the debug statement, and
we do not need a seperate if (log_level >= LOG_DEBUG) for the conversion.
dns_resource_key_to_string() is changed not to provide any whitespace
padding. Most callers were stripping the whitespace with strstrip(),
and it did not look to well anyway. systemd-resolve output is not column
aligned anymore.
The result of the conversion is not stored in DnsTransaction object
anymore. It is used only for debugging, so it seems fine to generate it
when needed.
Various debug statements are extended to provide more information.
The output didn't specify if the default for --cname/--search/--legend and
other options was yes or no. Change the description to be explicit about that.
man: show output in example systemd-resolve commands
I think example output allows the reader of the man page to
see what functionlity is provided without running the commands
themselves. Specific values in the examples are bound to get out
of date but this is not a problem.
resolved: make sure to normalize all domain names returned via the bus
Most domain names we deal with are normalized anyway (since we read them that
way from DNS packets), but some might not (because they are synthesized from
unnormalized configuration or so), hence make sure to normalize all names
before passing them out to clients, to be fully deterministic.
Note that internally we are process normalized and non-normalized names the
same way, and while comparing them ignore the differences due to unnormalized
names. However, that internal implementation detail really shouldn't spill out
the clients, hence make sure to clean it all up.
This patch makes networkd stay around as long as there is more than just a
loopback interface around, or the loopback device isn't fully probed yet, or
the loopback device has a .network file attached.
In essence, this means networkd stays around now continously as it should,
unless it is running in some (container?) environment that really has no
interface except a loopback device.
Before this patch existence of char16_t, char32_t, key_serial_t was checked
with AC_CHECK_DECLS() which doesn't actually work for types. Correct this to
use AC_CHECK_TYPES() instead.
Also, while we are at it, change the check for memfd_create() to use
AC_CHECK_DECLS() instead of AC_CHECK_FUNCS(). This is a better choice, since a
couple of syscalls are defined by glibc but not exported in the header files
(pivot_root() for example), and we hence should probably be more picky with
memfd_create() too, which glibc might decide to expose one day, but not
necessarily in the headers too.
resolved: turn on DNSSEC by default, unless configured otherwise
Let's make sure DNSSEC gets more testing, by defaulting DNSSEC to
"allow-downgrade" mode. Since distros should probably not ship DNSSEC enabled
by default add a configure switch to disable this again.
DNSSEC in "allow-downgrade" mode should mostly work without affecting user
experience. There's one exception: some captive portal systems rewrite DNS in
order to redirect HTTP traffic to the captive portal. If these systems
implement DNS servers that are otherwise DNSSEC-capable (which in fact is
pretty unlikely, but still...), then this will result in the captive portal
being inaccessible. To fix this support in NetworkManager (or any other network
management solution that does captive portal detection) is required, which
simply turns off DNSSEC during the captive portal detection, and resets it back
to the default (i.e. on) after captive portal authentication is complete.
If we are not PID 1 and started as init, we executing systemctl
with execv(). Here no need to set errno manually, because in a
failure case, because the execv() anyway will set errno depends
on a error.

time-util: Rename and fix call of deserialize_timestamp_value()
The deserialize_timestamp_value() is renamed timestamp_deserialize() to be more
consistent with dual_timestamp_deserialize()
And add the NULL check back on realtime and monotonic
Some newlines are added, but the output will still exceed 80 columns in many
cases. The fallback for oom conditions is changed from "n/a" to something
"<service>", and a similar pattern is used for the new code. This way we
have a realistic fallback for oom, which seems nicer than making the whole
function return an error code which would then have to be propagated.
$ systemctl -M fedora-rawhide restart systemd-networkd.service
Job for systemd-networkd.service failed because start of the service was attempted too often.
See "systemctl -M fedora-rawhide status systemd-networkd.service" and "journalctl -M fedora-rawhide -xe" for details.
To force a start use "systemctl -M fedora-rawhide reset-failed systemd-networkd.service"
followed by "systemctl -M fedora-rawhide start systemd-networkd.service" again.
The time-util.c provides dual_timestamp_deserialize() function to
convert value to usec_t and set it as value of ts->monotonic and
ts->realtime.
There are some places in code which do the same but only for one
clockid_t (realtime or monotonic), when dual_timestamp_deserialize()
sets value of both.
This patch introduces the deserialize_timestamp_value() which converts
a given value to usec_t and write it to a given timestamp.
