2015-07-01udev: destroy manager before cleaning environmentDavid Herrmann
Due to our _cleanup_ usage for the udev manager, it will be destroyed after the "exit:" label has finished. Therefore, it is the last destruction done in main(). This has two side-effects: - mac_selinux is destroyed before the udev manager is, possible causing use-after-free if the manager-cleanup accesses selinux data - log_close() is called *before* the manager is destroyed, possibly re-opening the log if you use --debug (and thus not re-applying the --debug option) Avoid this by moving the manager-handling into a new function called run(). This function will be left before we enter the "exit:" label in main(), hence, the manager object will be destroyed early.
2015-07-01login: re-use VT-sessions if they already existDavid Herrmann
Right now, if you start a session via 'su' or 'sudo' from within a session, we make sure to re-use the existing session instead of creating a new one. We detect this by reading the session of the requesting PID. However, with gnome-terminal running as a busname-unit, and as such running outside the session of the user, this will no longer work. Therefore, this patch makes sure to return the existing session of a VT if you start a new one. This has the side-effect, that you will re-use a session which your PID is not part of. This works fine, but will break assumptions if the parent session dies (and as such close your session even though you think you're part of it). However, this should be perfectly fine. If you run multiple logins on the same session, you should really know what you're doing. The current way of silently accepting it but choosing the last registered session is just weird.

2015-07-01Revert "kmod-setup: don't print warning on -ENOSYS"David Herrmann
This partially reverts commit 78d298bbc57e412574ea35e6e66f562d97fd9ebc. The changed coding-style is kept, but the ENOENT->ENOSYS conversion is reverted. kmod was fixed upstream to no longer return ENOSYS. Also see: https://git.kernel.org/cgit/utils/kernel/kmod/kmod.git/commit/?id=114ec87c85c35a2bd3682f9f891e494127be6fb5 The kmod fix is marked for backport, so no reason to bump the kmod version we depend on.

2015-06-30nspawn: determine_uid_shift before forkingRichard Maw
It is needed in one branch of the fork, but calculated in another branch. Failing to do this means using --private-users without specifying a uid shift always fails because it tries to shift the uid to UID_INVALID.
2015-06-30nspawn: Don't remount with fewer optionsRichard Maw
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.

2015-06-25logind: fix delayed execution regressionDaniel Mack
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.

2015-06-24sd-netlink: don't export internal type-system detailsDavid Herrmann
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.
2015-06-24sd-netlink: don't treat NULL as root type-systemDavid Herrmann
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.
2015-06-24sd-netlink: don't treat type_system->count==0 as invalidDavid Herrmann
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).
2015-06-24sd-netlink: make sure the root-level type is nestedDavid Herrmann
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.
2015-06-24sd-netlink: drop NETLINK_TYPE_METADavid Herrmann
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).
2015-06-24sd-netlink: turn 'max' into 'count' to support empty type-systemsDavid Herrmann
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.
2015-06-24sd-netlink: avoid casting size_t into intDavid Herrmann
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.
2015-06-24sd-netlink: make NLTypeSystem internalDavid Herrmann
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.
2015-06-24sd-netlink: make NLType internalDavid Herrmann
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.
2015-06-24sd-netlink: don't access type->type_system[_union] directlyDavid Herrmann
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.
2015-06-24sd-netlink: rename NLA_ to NETLINK_TYPE_David Herrmann
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.
