The ->done callback in the unit's vtable might call into
unit_unwatch_bus_name() and corrupt memory by that.
Move the call down, and clean up the bus slot in case it hasn't been done
yet.
Currently, PID1 installs an unfiltered NameOwnerChanged signal match, and
dispatches the signals itself. This does not scale, as right now, PID1
wakes up every time a bus client connects.
To fix this, install individual matches once they are requested by
unit_watch_bus_name(), and remove the watches again through their slot in
unit_unwatch_bus_name().
If the bus is not available during unit_watch_bus_name(), just store
name in the 'watch_bus' hashmap, and let bus_setup_api() do the installing
later.
When the user requests to set hostname, and we are setting both
pretty and static hostnames, and the name is a valid FQDN, we
use it as the static hostname, and unset the pretty hostname.
The change is that a FQDN with a trailing dot is accepted and ignored.
https://bugzilla.redhat.com/show_bug.cgi?id=1238246
Lowercasing of the static name is not done anymore.
$ hostnamectl set-hostname Foobar.
=> static is "Foobar", pretty is "Foobar."
$ hostnamectl set-hostname Foobar.org.
=> static is "Foobar.org", pretty is unset
$ hostnamectl set-hostname Foobar.org..
=> static is "Foobar.org", pretty is "Foobar.org.."
Tests are modified to check behaviour with relax and without relax.
New tests are added for hostname_cleanup().
Tests are moved a new file (test-hostname-util) because there's
now a bunch of them.
New parameter is not used anywhere, except in tests, so there should
be no observable change.
This stores private-zone DHCP options inside of their respective DHCP
lease. These options aren't used by networkd (what would it do with
them?), but saving them will allow other programs to query the values.
To improve performance, the options are stored in ascending order by
tag.
Let logind use the sd_bus_track helper object to track the controllers of
sessions. This does not only remove quite some code but also kills the
unconditional matches for all NameOwnerChanged signals.
The latter is something we should never ever do, as it wakes up the daemon
every time a client connects, which doesn't scale.
When command path has access label and no SmackProcessLabel= is not
set, default process label will be set. But if the default process
label has no rule for the access label of the command path then smack
access error will be occurred.
So, if the command path has execute label then the child have to set
its label to the same of execute label of command path instead of
default process label.
- Add smack xattr lookup table
- Unify all of mac_smack_apply_xxx{_fd}() to mac_smack_apply() and
mac_smack_apply_fd().
- Add smack xattr read apis similar with apply apis as
mac_smack_read{_fd}().
If the caller provides invalid assignments via
UpdateActivationEnvironment=, we now drop it and warn loudly about it. We
need this to be compatible to dbus1, but we also clearly want to tell the
caller that they better ought to follow POSIX recommendations and use
valid labels only.
Fixes#826.
Similar in function to LIST_INSERT_AFTER, this will insert a new element
into the list before the specified position. If the specified position
is NULL, the element is added as the tail of the list.
Absolute paths should be sufficient to prevent funny business,
and while path_is_safe() checks this, it also checks whether the path
contains . or .. components, which while odd, aren't a security risk.
In case of non-CLOCAL lines (i.e. those with carrier detect configured)
we shouldnt wait for a carrier if all we try to do is reset the TTY.
Hence, whenever we open such a TTY pass O_NONBLOCK.
Note that we continue to open ttys we intend to write to without
O_ONBLOCK, we only add it in cases we invoke ioctl()s or other terminal
operations without reading or writing to the device.
Fixes#835.
We should avoid using CLOCK_BOOTTIME directly unless we actually can
sensible distuingish it from CLOCK_MONOTONIC. CLOCK_BOOTTIME is only
fully feature on very recent Linux kernels, hence we should stick to a
fallback logic, which is already available in the
clock_boottime_or_monotonic() call.
Previously, if the event loop never ran before sd_event_now() would
fail. With this change it will instead fall back to invoking now(). This
way, the function cannot fail anymore, except for programming error when
invoking it with wrong parameters.
This takes into account the fact that many callers did not handle the
error condition correctly, and if the callers did, then they kept simply
invoking now() as fall back on their own. Hence let's shorten the code
using this call, and make things more robust, and let's just fall back
to now() internally.
Whether now() is used or the cache timestamp may still be detected via
the return value of sd_event_now(). If > 0 is returned, then the fall
back to now() was used, if == 0 is returned, then the cached value was
returned.
This patch also simplifies many of the invocations of sd_event_now():
the manual fall back to now() can be removed. Also, in cases where the
call is invoked withing void functions we can now protect the invocation
via assert_se(), acknowledging the fact that the call cannot fail
anymore except for programming errors with the parameters.
This change is inspired by #841.
