`systemd-tmpfiles --clean ./some.conf` doesn't work:
Failed to open './some.conf', ignoring: No such file or directory
`systemd-tmpfiles --clean $(realpath ./some.conf)` works fine.
This reverts commit 409c2a13fd.
It breaks the bootup of systems which enable smack at compile time, but have no
smack enabled in the kernel. This needs a different solution.
Let's use strjoina() rather than strjoin() for construct dbus match
strings.
Also, while we are at it, fix parameter ordering, so that our functions
always put the object first, like it is customary for OO-like
programming.
pthread APIs (unlike the rest of libc) return their errors as positive
error codes directly from the functions, rather than using errno. Let's
make sure we always handle things that way.
Clear up how we pass fd owner ship to proxy and bus objects. Document
that ownership is passed of the fds in question even in case of failing
constructors, and that callers should forget about fds pass into the
proxy object.
The alternative would be to duplicate the fds, but given that fds are a
relatively scarce and heavy resource let's better avoid that.
Fixes#1591.
Track the number of matches installed for a given multicast group, and leave the
group once no matches depend on it.
In order to handle passed-in sockets that are already members of multicast groups
we initialize the refcount based on the membership once we take over the socket.
This way we will leave the socket in the state we found it once we finish with
it.
On kernels that do not fully support reading out the multicast group membership
we fall back to never leaving any groups (as before).
If SMACK is enabled, 'smackfsroot=*' option should be specified in
tmp.mount file since many non-root processes use /tmp for temporary
usage. If not, /tmp is labeled as '_' and smack denial occurs when
writing.
--enable-lz4 can be used to force lz4 requirement,
--disable-lz4 can be used to skip lz4 support even if available.
Also, make surrounding checks for bzip2, xz, and zlib similar in structure.
This fixes the check for requested but missing bzip2.
Logging for compression and decompression is assymetrical on purpose:
if compiled without some type of compression, those compression code
paths should never be invoked. OTOH, it is possible to encounter
unsupported format on decompression, so leave those log_debug statements
in, to make it easier to diagnose stuff.
