2015-03-18libudev: private - introduce udev_device_new_from_synthetic_event()Tom Gundersen
This allows set_action(), read_uevent_file() and read_db() to be made internal to libudev. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>

2015-03-18selinux: fix SEGV during switch-root if SELinux policy loadedWill Woods
If you've got SELinux policy loaded, label_hnd is your labeling handle. When systemd is shutting down, we free that handle via mac_selinux_finish(). But: switch_root() calls mkdir_p_label(), which tries to look up a label using that freed handle, and so we get a bunch of garbage and eventually SEGV in libselinux. (This doesn't happen in the switch-root from initramfs to real root because there's no SELinux policy loaded in initramfs, so label_hnd is NULL and we never attempt any lookups.) So: make sure that mac_selinux_finish() actually sets label_hnd to NULL, so nobody tries to use it after it becomes invalid. https://bugzilla.redhat.com/show_bug.cgi?id=1185604 Signed-off-by: Anthony G.

2015-03-18Check that EWOULDBLOCK is the same as EAGAINZbigniew Jędrzejewski-Szmek
It certainly is everywhere on Linux, but as a courtesy to people doing some strange cross-compilation, check that the assumption holds. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>

2015-03-18udev-ctrl: fix strict aliasing issuesShawn Landden
it is ironic that "The only purpose of this structure is to cast the structure pointer passed in addr in order to avoid compiler warnings. See EXAMPLE below." from bind(2) Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
2015-03-18udev: downgrade "has devpath" and "filled with db file" messagesZbigniew Jędrzejewski-Szmek
Udev debug messages have to be significantly overhauled... For now just downgrade those two. They are responsible for approximately 25% of debug output during boot and are rather useless. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
2015-03-18udev: properly calculate size of remaining dataZbigniew Jędrzejewski-Szmek
The data comes from the kernel, so chances of it being garbled are low, but for correctness' sake, add the check. CID #996458. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
2015-03-18udev: make set_usec_initialized() internal to libudevTom Gundersen
Instead introduce ensure_usec_initialized(), which copies the timestamp if possible otherwise sets it to now(CLOCK_MONOTONIC). Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
2015-03-18path-util: fix path_is_mount_point() for symlinksHarald Hoyer
path_is_mount_point() compares the mount_id of a directory and the mount_id of the parent directory. When following symlinks, the function to get the parent directory does not take the symlink into account. /bin -> /usr/bin with /usr being a mountpoint: mount_id of /bin with AT_SYMLINK_FOLLOW != mount_id of / Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
2015-03-18udevd: improve handling of failed workerTom Gundersen
The information in the db is stale, so it does not make sense to expose it any longer. Also, don't drop the kernel event, but simply pass it on to userspace without ammending it. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
2015-03-18udevd: don't free event when killing the worker, wait until it has been reapedTom Gundersen
This will allow us to clean up the device when we are notified about the worker being killed. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
2015-03-18libudev: introduce clone_with_db()Tom Gundersen
This allows us to move the db reading from udevd to libudev. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
2015-03-18libudev: monitor - fix error path in send_deviceTom Gundersen
Return -errno rather than -1 in case sendmsg() fails. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
2015-03-18udevd: event - make db loading lazy in REMOVE event handlingTom Gundersen
We were explicitly eagerly loading the db, then deletenig the backing file and then processing the rules/symlinks. Instead we delete the backnig db file as the last step and let the db loading be lazy as everywhere else. This may save us a bit of work in casese where the db is not needed, but more importantly it hides some implementation details of libudev-device form udevd. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
2015-03-18libudev: introduce udev_device_properties_copy()Tom Gundersen

2015-03-18udev/libudev: event - move {OLD_,}INTERFACE handling from udevd to libudevTom Gundersen
This should be internal to the library as it is only about reflecting the sysfs state in the udev_device. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>

2015-03-18rules: drop redundant matchDavid Herrmann
The 60-keyboard rules are already guared by KERNEL!="event*" bail-outs, therefore, KERNELS="input*" is always true. Drop it! Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
2015-03-18hwdb: support bluetooth keyboard fixupsDavid Herrmann
Drop the restriction not to match on bluetooth devices. They are supported just fine! Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
2015-03-18hwdb: convert to generic input-modalias matchesDavid Herrmann
There is no reason to match on usb-modaliases, if we can use the input-modalias to achieve the same. This commit changes the keyboard-lookups to not be restricted to USB, but pass all modaliases to the hwdb. Furthermore, we convert all usb:* matches to input:* matches, thus getting rid of any ambiguity if multiple usb devices are chained (or a bluetooth device / etc. is on top). Note that legacy keyboard:usb:* matches are still supported, but deprecated. If possible, please use keyboard:input:* matches instead. This is a required step to make other input devices work with 60-keyboard.hwdb. Other bus-types are often chained on usb and we want to avoid any ambiguity here if we incorrectly match on a USB hub.

2015-03-18rules: storage - relace blacklist with explicit whitelistKay Sievers
Newly added kernel drivers repeatedly pass our blacklist and cause trouble for the devices, because they do not expect to be examined by udev's default rules which include blkid. This turns the blacklist into a whitelist. Device type which need support for additional symlinks need to be added to the whitelist now. Note, that the by-id, by-path symlinks are only intended for hotpluggable devices. There is no reason for exotic, or for statically configured devices to provide them. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>

2015-03-01shared: introduce cmsg_close_all() callLennart Poettering
The call iterates through cmsg list and closes all fds passed via SCM_RIGHTS. This patch also ensures the call is used wherever appropriate, where we might get spurious fds sent and we should better close them, then leave them lying around. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
2015-03-01rules: simplify mmc RPMB handlingeudev/v3.0Martin Pitt
We don't actually want a by-path/ symlink for MMC RPMB devices, so just add them to the blacklist. This will prevent creating wrong by-path links and blkid'ing those. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
2015-03-01rules: Fix by-path of mmc RPMB partitions and don't blkid themMartin Pitt
Linux 3.10+ exposes RPMB (Replay Protected Memory Block) partitions of MMC devices [1] ; trying to read them with blkid or other unspecific means will cause kernel buffer I/O errors and timeouts. So don't run blkid on these. Also ensure that /dev/disk/by-path creates proper symlinks and exposes the -rpmb partition separately, instead of letting the "normal" partition symlink point to the rpbm device (this is a race condition).
