nspawn: Don't remount with fewer options
|
|
core: handle --log-target=null when calling systemd-shutdown
|
|
When we do a MS_BIND mount, it inherits the flags of its parent mount.
When we do a remount, it sets the flags to exactly what is specified.
If we are in a user namespace then these mount points have their flags
locked, so you can't reduce the protection.
As a consequence, the default setup of mount_all doesn't work with user
namespaces. However if we ensure we add the mount flags of the parent
mount when remounting, then we aren't removing mount options, so we
aren't trying to unlock an option that we aren't allowed to.

When shutting down, if systemd was started with --log-target=null,
systemd-shutdown was being called with --log-target=console.

man: remove repeated word "the" and polish

|

While the LSB suggests only [A-Za-z0-9], that doesn't prevent admins
from doing the wrong thing. Lets not generate invalid names in
that case.

Do not assume that a non-service unit type is a target.

Me again :) Just noticed one of these in a manpage and did another pass
to clean them up. See 16dad32e437fdf2ffca03cc60a083d84bd31886f for
explanation, though the link needs updating:

bootchart: reset list_sample_data head before generating SVG

systemd.service.xml: document that systemd removes the PIDFile
|
|
|
|
Until commit 1f2ecb0 ("bootchart: kill a bunch of global variables")
variable "head" was declared global and this action was performed by svg_header.
Now that "head" is local and passed to each function called by svg_do(...)
move the code at the beginning of svg_do(...) to restore the correct behaviour.

Revert "hwdb: add a touchpad hwdb"
|
|
The main purpose of this hwdb was to tag touchpads that have the physical
trackstick buttons wired to the touchpad (Lenovo Carbon X1 3rd, Lenovo *50
series). This hwdb is not required on kernels 4.0 and above, the kernel now
re-routes button presses through the trackstick's device node. Userspace does
not need to do anything.
See kernel commit cdd9dc195916ef5644cfac079094c3c1d1616e4c.
This reverts commit 001a247324b44c0e0b8fdba41a6fc66e7465b8b6.

Commit c0f32805 ("logind: use sd_event timer source for inhibitor
logic") reworked the main loop logic of logind so that it uses a
real timeout callback handler to execute delayed functions.
What the old code did, however, was to call those functions on
every iteration in the main loop, not only when the timeout
expired.
Restore that behavior by bringing back manager_dispatch_delayed(),
and call it from manager_run(). The internal event source callback
manager_inhibit_timeout_handler() was turned into a wrapper of
manager_dispatch_delayed() now.

Maybe there is some left-over value stored in r from previous function
call. Let's make sure we always return consistent error code when we reach end of
the function body.
Fixes following crash of test-install,
Assertion 'r == 0' failed at src/test/test-install.c:52, function main(). Aborting.

bus-proxy: ignore 'log' attributes in XML policy

'log' is unsupported but nothing to warn about. Ignore it just like we
ignore 'eavesdrop'.

The kernel bonding layer allows passing an array of ARP IP targets as
bond-configuration. Due to the weird implementation of arrays in netlink
(which we haven't figure out a generic way to support, yet), we usually
hard-code the supported array-sizes. However, this should not be exported
from sd-netlink.
Instead, make sure the caller just uses it's current hack of enumerating
the types, and the sd-netlink core will have it's own list of supported
array-sizes (to be removed in future extensions, btw!). If either does not
match, we will just return a normal error.
Note that we provide 2 constants for ARP_IP_TARGETS_MAX now. However, both
have very different reasons:
- the constant in netdev-bond.c is used to warn the user that the given
number of targets might not be supported by the kernel (even though the
kernel might increase that number at _any_ time)
- the constant in sd-netlink is solely used due to us missing a proper
array implementation. Once that's supported in the type-system, it can
be removed without notice
Last but not least, this patch turns the log_error() into a log_warning().
Given that the previous condition was off-by-one, anyway, it never hit at
the right time. Thus, it was probably of no real use.

Explicitly export the root type-system to the type-system callers. This
avoids treating NULL as root, which for one really looks backwards (NULL
is usually a leaf, not root), and secondly prevents us from properly
debugging calling into non-nested types.
Also rename the root to "type_system_root". Once we support more than
rtnl, well will have to revisit that, anyway.
|
|
Empty type-systems are just fine. Avoid the nasty hack in
union-type-systems that treat empty type-systems as invalid. Instead check
for the actual types-array and make sure it's non-NULL (which is even true
for empty type-systems, due to "empty_types" array).
|
|
In sd-netlink-message, we always guarantee that the currently selected
type-system is non-NULL. Otherwise, we would be unable to parse any types
in the current container level. Hence, this assertion must be true:
message->container_type_system[m->n_containers] != NULL
During message_new() we currently do not verify that this assertion is
true. Instead, we blindly access nl_type->type_system and use it (which
might be NULL for basic types and unions). Fix this, by explicitly
checking that the root-level type is nested.
Note that this is *not* a strict requirement of netlink, but it's a strict
requirement for all message types we currently support. Furthermore, all
the callers of message_new() already verify that only supported types are
passed, therefore, this is a pure cosmetic check. However, it might be
needed on the future, so make sure we don't trap into this once we change
the type-system.
|
|
The NETLINK_TYPE_META pseudo-type is actually equivalent to an empty
nested type. Drop it and define an empty type-system instead.
This also has the nice side-effect that m->container_type_system[0] is
never NULL (which has really nasty side-effects if you try to read
attributes).
|
|
Right now we store the maximum type-ID of a type-system. This prevents us
from creating empty type-systems. Store the "count" instead, which should
be treated as max+1.
Note that type_system_union_protocol_get_type_system() currently has a
nasty hack to treat empty type-systems as invalid. This might need some
modification later on as well.
|
|
size_t is usually 64bit and int 32bit on a 64bit machine. This probably
does not matter for netlink message sizes, but nevertheless, avoid
hard-coding it anywhere.
|
|
Same as NLType, move NLTypeSystem into netlink-types.c and hide it from
the outside. Provide an accessor function for the 'max' field that is used
to allocate suitable array sizes.
Note that this will probably be removed later on, anyway. Once we support
bigger type-systems, it just seems impractical to allocate such big arrays
for each container entry. An RBTree would probably do just fine.
|
|
If we extend NLType to support arrays and further extended types, we
really want to avoid hard-coding the type-layout outside of
netlink-types.c. We already avoid accessing nl_type->type_system outside
of netlink-types.c, extend this to also avoid accessing any other fields.
Provide accessor functions for nl_type->type and nl_type->size and then
move NLType away from the type-system header.
With this in place, follow-up patches can safely turn "type_system" and
"type_system_union" into a real "union { }", and then add another type for
arrays.
|
|
Make sure we never access type->type_system or type->type_system_union
directly. This is an implementation detail of the type-system and we
should always use the accessors. Right now, they only exist for 2-level
accesses (type-system to type-system). This patch introduces the 1-level
accessors (type to type-system) and makes use of it.
This patch makes sure the proper assertions are in place, so we never
accidentally access sub-type-systems for non-nested/union types.
Note that this places hard-asserts on the accessors. This should be fine,
as we expect callers to only access sub type-systems if they *know*
they're dealing with nested types.
|
|
The NLA_ names are used to name real datatypes we extract out of netlink
messages. The kernel has an internal enum with the same names
(NLA_foobar), which is *NOT* binary compatible to our types. Furthermore,
we support a different set of types than the kernel (as we try to treat
some kernel peculiarities as our own types to simplify the API).
Rename NLA_ to NETLINK_TYPE_ to make clear that this is our own set of
types.

It is not udev's task to apply any of these setting that way, or
from udev rules files. Things need to be sortet out in the kernel,
or explicit whitelist can possibly be added to the hardware database.
Until that is sorted out, and general agreement, udev is not
willing to maintain any such lists or power management settings
in general.
"Thanks for digging this out! I thought my Kinesis keyboard got broken
and ordered a new one, only to find out that the new one doesn't work
as well. I'm not sure whether we should start collecting a blacklist
of keyboards which don't work with USB autosuspend, or rather a
whitelist? Or revert this wholesale?"
