fixes Coverity #1328493

ReadOnlyDirectories=-/ works fine
|
|
systemd-run can launch units with ReadWriteDirectories, ReadOnlyDirectories, InaccessibleDirectories
|
|
Every time the state is written out we may trigger third-party apps, so
let's be a bit more careful about writing this out unnecessarily.

We only keep the addresses that we added ourselves in link->addresses, and
introduce a new set link->addresses_foreign to keep addresses of unknown
origin.
Only functional change is that "foreign" addresses no longer prevent a link
from entering "configured" state.
|
|
Establish the firewall rule before creating the address, and do not create the address
if the firewall rule could not be created. Also, only drop the firewall rule once
the address has been removed from the kernel.
|
|
These functions are almost entirely the same, so avoid duplication.
|
|
Call back into link_check_ready() whenever an address state change may have
made a link ready.
|
|
We were considering a link configured whilst its IPv6 addresses were still
tentative.
Fixes issue #650.

networkd: add support to configure IPv6 DAD

* `Environment=` resets previous assignments
* `Environment='a=1 b=2'` sets `a` to `1` and `b` to `2`
* `Environment='"a=1 2" b=2"'` sets `a` to `1 2` and `b` to `2`

nspawn: skip /sys-as-tmpfs if we don't use private-network
|
|
Since v3.11/7dc5dbc ("sysfs: Restrict mounting sysfs"), the kernel
doesn't allow mounting sysfs if you don't have CAP_SYS_ADMIN rights over
the network namespace.
So the mounting /sys as a tmpfs code introduced in
d8fc6a000fe21b0c1ba27fbfed8b42d00b349a4b doesn't work with user
namespaces if we don't use private-net. The reason is that we mount
sysfs inside the container and we're in the network namespace of the host
but we don't have CAP_SYS_ADMIN over that namespace.
To fix that, we mount /sys as a sysfs (instead of tmpfs) if we don't use
private network and ignore the /sys-as-a-tmpfs code if we find that /sys
is already mounted as sysfs.
Fixes #1555

A bit snake-oilish, but can't hurt.

Fixes one of the issues pointed out in #1522.

it's exposed as uint32_t and it is internally an uint32_t, hence no need
to treat it as an unsigned.

Hook more properties for transient units

systemd-run can now launch units with EnvironmentFile set.

systemd-run can launch units with OOMScoreAdjust

bus proxy fixes, and more
|
|
|
|
|
|
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).

btrfs doesn't do that automatically, hence let's do that explicitly each
time.

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.
