Let's add a way to get the type-specific D-Bus interface of a unit from
either its type or name to src/basic/unit-name.[ch]. That way we can
share it with the client side, where it is useful in tools like cgls or
machinectl.
Also ports over machinectl to make use of this.

Add 'machinectl shell' to NEWS and also update date and contributors
lists.

We should not fall back to dbus-1 and connect to the proxy when kdbus
returns an error that indicates that kdbus is running but just does not
accept new connections because of quota limits or something similar.
Based on a patch by Kay.

This reverts commit d4d00020d6ad855d65d31020fefa5003e1bb477f. The idea of
the commit is broken and needs to be reworked. We really cannot reduce
the bus-addresses to a single address. We always will have systemd with
native clients and legacy clients at the same time, so we also need both
addresses at the same time.
|
|
It is not acceptable to load unit files during enable/disable operations
just to figure out the selinux labels. systemd implements lazy loading
for units, so the selinux hooks need to follow it.
This drops the mac_selinux_unit_access_check_strv() helper which
implements a non-acceptable policy check. If anyone cares for that
functionality, you really should pass a callback+userdata to the helpers
in src/shared/install.c which does policy checks on each touched file.
See #1050 on github for more.

We use dashes in our bloom-tags. Make sure the newly introduced arg0has
tag uses the same style.
Note that the external dbus-tags don't use dashes, though. They are
defined in the spec and we need to keep compatibility there.

strv_extend() does not consume the passed entry, hence, we must properly
free it. Furthermore, we should *not* use strv_consume() as we do greedy
allocations on 'ret'; and greedy-allocations should only be used for short
lived objects or caches.
Fix the domainname parser to properly free temporary storage when done.

In our API design, getter-functions don't ref objects. Calls like
foo_get_bar() will not ref 'bar'. We never do that and there is no real
reason to do it in single threaded APIs. If you need a ref-count, you
better take it yourself *BEFORE* doing anything else on the parent object
(as this might invalidate your pointer).
Right now, sd_dhcp?_get_lease() refs the lease it returns. A lot of
code-paths in systemd do not expect this and thus leak the lease
reference. Fix this by changing the API to not ref returned objects.

Also mention explicitly that the security properties (i.e. SELinux) are
also isolated when "machinectl shell" is used.

paths are specified
The commit 4938696301a914ec26bcfc60bb99a1e9624e3789 overlooked the
fact that unit files can be specified as unit file paths, not unit
file names, wrongly passing a unit file path to the 1st argument of
manager_load_unit() that handles it as a unit file name. As a result,
the following 4 systemctl subcommands:
enable
disable
reenable
link
mask
unmask
fail with the following error message:
# systemctl enable /usr/lib/systemd/system/kdump.service
Failed to execute operation: Unit name /usr/lib/systemd/system/kdump.service is not valid.
# systemctl disable /usr/lib/systemd/system/kdump.service
Failed to execute operation: Unit name /usr/lib/systemd/system/kdump.service is not valid.
# systemctl reenable /usr/lib/systemd/system/kdump.service
Failed to execute operation: Unit name /usr/lib/systemd/system/kdump.service is not valid.
# cp /usr/lib/systemd/system/kdump.service /tmp/
# systemctl link /tmp/kdump.service
Failed to execute operation: Unit name /tmp/kdump.service is not valid.
# systemctl mask /usr/lib/systemd/system/kdump.service
Failed to execute operation: Unit name /usr/lib/systemd/system/kdump.service is not valid.
# systemctl unmask /usr/lib/systemd/system/kdump.service
Failed to execute operation: Unit name /usr/lib/systemd/system/kdump.service is not valid.
To fix the issue, first check whether a unit file is passed as a unit
file name or a unit file path, and then pass the unit file to the
appropreate argument of manager_load_unit().
By the way, even with this commit mask and unmask reject unit file
paths as follows and this is a correct behavior:
# systemctl mask /usr/lib/systemd/system/kdump.service
Failed to execute operation: Invalid argument
# systemctl unmask /usr/lib/systemd/system/kdump.service
Failed to execute operation: Invalid argument

Set _EXEC_UTMP_MODE_INVALID to -1. This matches the return value from
string_table_lookup.
|

Internally, the root cgroup is stored as the empty string in
Unit.cgroup_path, and "no cgroup" as NULL. Unfortunately, D-Bus does not
know a NULL concept, hence when reporting the cgroup to clients we
should turn the root cgroup into "/", and leave the empty string for the
"no cgroup" case.
This should make sure that "systemctl status -- -.slice" works correctly
and shows the entire cgroup tree.

Fixes #1018.
Based on a patch from Seth Jennings.
|
|
|
|
In the Cockpit integration tests we hang onton the journal files
for a failed test and would like to inspect them using coredumpctl.
This commit adds the ability to specify an alternate directory
for coredumpctl to read the journal from.
|

Previously, sd-bus inofficially already supported bus matches that
tested a string against an array of strings ("as"). This was done via an
enhanced way to interpret "arg0=" matches. This is problematic however,
since clients have no way to determine if their respective
implementation understood strv matches or not, thus allowing invalid
matches to be installed without a way to detect that.
This patch changes the logic to only allow such matches with a new
"arg0has=" syntax. This has the benefit that non-conforming
implementations will return a parse error and a client application may
thus efficiently detect support for the match type.
Matches of this type are useful for "udev"-like systems that "tag" objects
with a number of strings, and clients need to be able to match against
any of these "tags".
The name "has" takes inspiration from Python's ".has_key()" construct.

Some flags are defined differently on unicast DNS and LLMNR, let's
document this in the DNS_PACKET_MAKE_FLAGS() macro.
|
|
This partially reverts 106784ebb7b303ae471851100a773ad2aebf5b80, ad
readds separate DNS_PACKET_MAKE_FLAGS() invocations for the LLMNR and
DNS case. This is important since SOme flags have different names and
meanings on LLMNR and on DNS and we should clarify that via the comments
and how we put things together.
|
|
This hopefully makes this a bit more expressive and clarifies that the
fd is not used for the DNS TCP socket. This also mimics how the LLMNR
UDP fd is named in the manager object.
