Actually unref the buscreds when we are not going to return a
pointer to them. As when bus_creds_add_more fails we immediately
return the error code otherwise and leak the new buscreds.
Found with coverity. Fixes: CID#1237761

After a section of memory is succesfully allocated, some of the following
actions can still fail due to lack of memory. In this case -ENOMEM is
returned without actually freeing the already mapped memory.
Found with coverity. Fixes: CID#1237762

We currently print weird error-messages if xkbcommon fails (which cannot
fail so far, but might in the future). Fix the uninitialized variable
warnings by setting 'r' correctly.
Thanks to Philippe De Swert for catching this (via coverity).

In case set_consume goes wrong, the pattern name has already been
freed. So we do not try to print it in the logs, assuming the pattern
addition print will be printed just before the failure anyway. Found
with coverity. Fixes: CID#1237798

m->kdbus could be freed before it is released. Changing the
order fixes the issue.

This assertion is already there two lines down. Drop the redundant
assertion.

This might cause >=0 to be returned, even though the method failed. Fix
this and return -errno.

If we enable a session, any probed device might get immediately enabled.
This might cause TakeDevice() messages to be sent before we call
TakeControl(). Therefore, enable sessions *after* sending TakeControl() so
we always succeed if TakeControl() succeeds.
|
|
We don't use set.h so no need to include it. We used to include it for
temporary refs on all idev devices of a session, but that never was pushed
upstream.

This extends the udev parser to support OP_REMOVE (-=) and adds support
for TAG-= to remove previously set tags. We don't fail if the tag didn't
exist.
This is pretty handy if we ship default rules for seat-assignments and
users want to exclude specific devices from that. They can easily add
rules that drop any automatically added "seat" tags again.
|
|
We define typedefs for all internal types so drop the redundant "struct"
prefix.
|
|
If read() fails on evdev devices, we deal with this in idev_evdev_hup().
It is very likely this is an async revoke, therefore, we must not abort.
Fix our io helper to discard such errors after passing them to
idev_evdev_hup(), so we don't bail out of the event loop.
|
|
When the state restore is disabled, we would print:
"Unknown verb: load" instead of simply skipping loading the
state.
|
|
Some kernel modules still take more than one minute to insmod, we no longer rely on the timeout
killing insmod within a given period of time, so just bump this to a much higher value. Its only
purpose is to make sure that nothing stays aronud forever.

Verify that the Elapsed Time option is present.
|
|
Implement Elapsed Time option as it is defined as MUST in RFC 3315,
section 22.9. The elapsed time value is a 1/100th of a second with
a max value of 0xffff, i.e. 655.35 seconds.
As the main loop might not be running yet when sd_dhcp6_client_start() is
called, fetch the monotonic time directly and not from the event loop
while in state DHCP6_STATE_STOPPED.

The only remaining user was 'starting version XXX', which is now logged using log_info().
|
|
As of 3.17, the kernel will do this on its own, so just do regular log_debug() logging from udev.
|
|
|
|
Creating the rtnl context is cheap, but freeing it may not be, due to
synchronous close().
Also drop some excessive logging. We now log about the changing ifname
exactly once.

We already call this on via bus_event_loop_with_idle on exit. This
makes machined consistent with other similar daemons: localed,
hostnamed, timedated.

This lets the routing metric for links to be specified per-network,
still defaulting to DHCP_ROUTE_METRIC (1024) if unspecified. Hopefully
this helps with multiple interfaces configured via DHCP.

This makes DHCPv4 and IPv4LL coexist peacefully.
[tomegun: apply to both the dhcp routes, use in_addr_is_null() rather than a
separate variable to indicate when prefsrc should be applied]

This way we are sure that /dev/net/tun has been given the right permissions before we try to connect to it.
Ideally, we should create tun/tap devices over netlink, and then this whole issue would go away.

If BusPolicy= was passed, the parser function will have created
an ExecContext->bus_endpoint object, along with policy information.
In that case, create a kdbus endpoint, and pass its path name to the
namespace logic, to it will be mounted over the actual 'bus' node.
At endpoint creation time, no policy is updloaded. That is done after
fork(), through a separate call. This is necessary because we don't
know the real uid of the process earlier than that.
|
|
|
|
If a path to a previously created custom kdbus endpoint is passed in,
bind-mount a new devtmpfs that contains a 'bus' node, which in turn in
bind-mounted with the custom endpoint. This tmpfs then mounted over the
kdbus subtree that refers to the current bus.
This way, we can fake the bus node in order to lock down services with
a kdbus custom endpoint policy.
|
|
Add a new directive called BusPolicy to define custom endpoint policies. If
one such directive is given, an endpoint object in the service's ExecContext is
created and the given policy is added to it.
|
|
Custom endpoints are alternative connection points to a bus, allowing
specific policy to be uploaded.
Add two functions to bus-kernel. One to create such endpoints, and another
one for setting a policy for them.
|
|
Add types to describe endpoints and associated policy entries,
and add a BusEndpoint instace to ExecContext.
|
|
In order to re-use the policy definitions, factor them out into their own
files.
