In order to check for matching policy entries at message transfers, we
have to consider the following:
* check the currently owned names of both the sending and the receiving
peer. If the sending peer is connected via kdbus, the currently owned
names are already attached to the message. If it was originated by the
connection we're proxying for, we store the owned names in our own strv
so we can check against them.
* Walk the list of names to check which name would allow the message to
pass, and explicitly use that name as destination of the message. If the
destination is on kdbus, store both the connection's unique name and the
chosen well-known-name in the message. That way, the kernel will make sure
the supplied name is owned by the supplied unique name, at the time of
sending, and return -EREMCHG otherwise.
* Make the policy checks optional by retrieving the bus owner creds, and
when the uid matches the current user's uid and is non-null, don't check
the bus policy.

This reverts commit 5bb24cccbce846c0d77e71b70a3be7f4b2ba6c0e.

Retrieve the bus owner creds, and when the uid matches the current user's
uid and is non-null, don't check the bus policy.
|
|
We need to figure out which of the possible names satisfied the policy,
so we cannot do the iteration in check_policy_item() but have to leave it
to the users.
Test cases amended accordingly.

Store names successfully acquired by the legacy client into a hashmap.
We need to take these names into account when checking for send policies.

kdbus learned to accept both a numerical destination ID as well as a
well-known-name. In that case, kdbus makes sure that the numerical ID is in
fact the owner of the provided name and fails otherwise.
This allows for race-free assertion of a bus name owner while sending a
message, which is a requirement for bus-proxyd.
Add two new fields to sd_bus_message, and set the numerical ID to
verify_destination_id if bus_message_setup_kmsg() is called for a
message with a well-known name.
Also, set the destination's name in the kdbus item to .destination_ptr
if it is non-NULL.
Normal users should not touch these fields, and they're not publicy
accessible.

This should make the unquoting scheme a bit less naive.

Also, correct mentions of "units" instead of "unit files" in the table,
and terminate all sentences with a full stop.
|

If a unit contains only Also=, with no Alias= or WantedBy=, it shouldn't
be reported as static. New 'indirect' status shall be introduced.

Usually there are a few delay inhibitors all the time (NetworkManager,
Telepathy, etc.), but I'm only interested in the block ones.

This effectively reverts 599b6322f19ec619ddc294d0e7880b669040cf66, which
in turn partially reverted 4dc5b821ae737914499119e29811fc3346e3d97c.
The --failed switch is not documented on purpose, since it is redundant
due to --state=failed, which it predates. Due to that it's not
documented in --help either.
We generally try to avoid redundant interfaces, but if we need to keep
them for compatibility we do so, however remove them from documentation
to ensure they are not used in future.
The man page is now changed to include a comment about the fact that
--failed is not documented on purpose. Also, explicitly mention
--state=failed as example for --state.

Use the same robust logic of mkdir + unlink of any existing AF_UNIX
socket, ignoring the return value, right before bind().

Also simplify the code a bit by moving mkdir to the common path.

A timer configured with OnActiveSec will start its associated unit again
if the timer is stopped, then started. However, if the timer unit is
restarted -- with "systemctl restart", say -- this does not occur.
This commit ensures that TIMER_ACTIVE timers are re-enabled whenever the
timer is started, even if that's within a restart job.

After all, this is about files, not arguments, hence EFBIG is more
appropriate than E2BIG
