Previously, we supported GPT auto-discovery for /home and /srv, but not for the root partition. Add that, too. Fixes: #859
2016-12-16core: make mount units from /proc/self/mountinfo possibly bind to a device ↵Franck Bui
(#4515) Since commit 9d06297, mount units from mountinfo are not bound to their devices anymore (they use the "Requires" dependency instead). This has the following drawback: if a media is mounted and the eject button is pressed then the media is unconditionally ejected leaving some inconsistent states. Since udev is the component that is reacting (no matter if the device is used or not) to the eject button, users expect that udev at least try to unmount the media properly. This patch introduces a new property "SYSTEMD_MOUNT_DEVICE_BOUND". When set on a block device, all units that requires this device will see their "Requires" dependency upgraded to a "BindTo" one. This is currently only used by cdrom devices. This patch also gives the possibility to the user to restore the previous behavior that is bind a mount unit to a device. This is achieved by passing the "x-systemd.device-bound" option to mount(8). Please note that currently this is not working because libmount treats the x-* options has comments therefore they're not available in utab for later application retrievals.
2016-12-15rules: identify internal sound cards on platform bus (#4893)Daniel Drake
We have a system which has the HDMI audio capability internally, but pulseaudio is not giving it a very high priority compared to e.g. USB sound cards. The sound device appears on the platform bus and it is not currently tagged with any form factor information. It seems safe to assume that any sound card that is directly on the platform bus is of internal form factor, but we must be careful because udev rules will match all parent devices, not just the immediate parent, and you will frequently encounter setups such as: Platform bus -> USB host controller -> USB sound card In that case, SUBSYSTEMS==platform would match even though we're clearly working with an external USB sound card. In order to detect true platform devices here, we rely on the observation that if any parent devices of the sound card are PCI, USB or firewire devices, then this sound card cannot directly connected to the platform bus. Otherwise, if we find a parent device on the platform bus, we assume this is an internal sound card connected directly to the platform bus.
2016-12-10udev: Add rules for accelerometer orientation quirksBastien Nocera
This commit adds a rules file to extract the properties from hwdb to set on i2c IIO devices. This is used to set the ACCEL_MOUNT_MATRIX property on IIO devices, to be consumed by iio-sensor-proxy or equivalent daemon. The hwdb file contains documentation on how to write quirks. Note however that mount information is usually exported in: - the device-tree for ARM devices - the ACPI DSDT for Intel-compatible devices but currently not extracted by the kernel. Also note that some devices have the framebuffer rotation that changes between the bootloader and the main system, which might mean that the accelerometer is then wrongly oriented. This is a missing feature in the i915 kernel driver: https://bugs.freedesktop.org/show_bug.cgi?id=94894 which needs to be fixed, and won't require quirks.

2016-07-20rules: make sure always set at least one property on rfkill devicesLennart Poettering
The rfkill service waits for rfkill device initialization as reported by udev_device_is_initialized(), and if that is never reported it might dead-lock. However, udev never reports completed initialization for devices that have no properties or tags set. For some rfkill devices this might be the case, in particular those which are connected to exotic busses, where path_id returns nothing. This patch simply sets the SYSTEM_RFKILL property on all rfkill devices, to ensure that udev_device_is_initialized() always reports something useful and we don't dead-lock. Fixes: #2745
2016-07-15rules: UDEV_DISABLE_PERSISTENT_STORAGE_RULES_FLAG property (#3714)Rusty Bird
Sometimes, the persistent storage rules should be skipped for a subset of devices. For example, the Qubes operating system prevents dom0 from parsing untrusted block device content (such as filesystem metadata) by shipping a custom 60-persistent-storage.rules, patched to bail out early if the device name matches a hardcoded pattern. As a less brittle and more flexible alternative, this commit adds a line to the two relevant .rules files which makes them test the value of the UDEV_DISABLE_PERSISTENT_STORAGE_RULES_FLAG device property, modeled after the various DM_UDEV_DISABLE_*_RULES_FLAG properties.
2016-07-08rules: block: add support for pmem devices (#3683)bgbhpe
Persistent memory devices can be exposed as block devices as /dev/pmemN and /dev/pmemNs. pmemN is the raw device and is byte-addressable from within the kernel and when mmapped by applications from a DAX-mounted file system. pmemNs has the block translation table (BTT) layered on top, offering atomic sector/block access. Both pmemN and pmemNs are expected to contain file systems. blkid(8) and lsblk(8) seem to correctly report on pmemN and pmemNs. systemd v219 will populate /dev/disk/by-uuid/ when, for example, mkfs is used on pmem, but systemd v228 does not. Add pmem to the whitelist.
2016-07-01hwdb: add a 70-touchpad.hwdb to tag internal vs external touchpadsPeter Hutterer
Add a new key ID_INPUT_TOUCHPAD_INTEGRATION=internal|external so we have a single source for figuring out which touchpads are built-in. Fairly simple approach: bluetooth is external, usb is external unless it's an Apple touchpad. Everything else is internal.
2016-07-01rules: set ID_BUS for bluetooth, rmi and i8042Peter Hutterer
Something has to so we can have udev rules rely on this. Right now the ID_BUS setting is inconsistent: usb is set, ata and pci are set, bluetooth is not set, rmi is too new to be featured. 70-mouse even relied on bluetooth even though it was never set

2016-04-18Mark nbd as inactive until connected (#2422)Wouter Verhelst
Currently, 99-systemd.rules.in contains a line for network block devices, which mark them as inactive until the first change event, and as active from then on forward. This is not correct. A network block device can be connected or disconnected; this state is signalled by the presence or absense of a "pid" file, which contains the PID of the nbd client userspace process that started the connection. Update the rules file so that it checks for the presence of that file to decide what to set SYSTEMD_READY to. Note that current kernels do issue a change event upon connecting the device, but not yet upon disconnecting. While it's possible to wait until that's been fixed, the behaviour of the rule with TEST!="pid" in the absence of a proper uevent is exactly the same as the behaviour of the old rule; so it should be safe to apply now.

ADD event (#2747) The "SYSTEMD_READY=0" will cause automatic unmount of mountpoint that is on top of such DM device if this is used with multipath which sets DM_UDEV_DISABLE_OTHER_RULES_FLAG in case we have a CHANGE event thatcomes after DM multipath device reload when one of the paths is down or up.

2015-10-01rfkill: rework and make it listen on /dev/rfkillLennart Poettering
With this rework we introduce systemd-rfkill.service as singleton that is activated via systemd-rfkill.socket that listens on /dev/rfkill. That way, we get notified each time a new rfkill device shows up or changes state, in which case we restore and save its current setting to disk. This is nicer than the previous logic, as this means we save/restore state even of rfkill devices that are around only intermittently, and save/restore the state even if the system is shutdown abruptly instead of cleanly. This implements what I suggested in #1019 and obsoletes it.

rules: remove all power management from udev
2015-06-26Revert "hwdb: add a touchpad hwdb"Peter Hutterer
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.
2015-06-24rules: remove all power management from udevKay Sievers
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?" https://github.com/systemd/systemd/issues/340

2015-04-23rules: Add more firewire properties for sound, to be closer to USB and PCIAdam Goode
USB and PCI soundcards have a nice set of ID_* properties. It would be handy for firewire soundcards to have the same. Note that this removes the explicit setting of ID_ID in the firewire conditional. Because we are now setting ID_SERIAL, ID_ID will come from later in the file.
2015-04-23rules: Don't use ALSA card id in ID_IDAdam Goode
The ALSA id sysattr is generated by the sound subsystem and is not a stable identifier. It is generated though some string manipulation then made unique if there is a conflict. This means that it is enumeration-dependent and shouldn't be used for ID_ID. If ID_ID is supposed to be system-unique, it is not already since for firewire it is generated from the guid and there are broken firewire devices that have duplicate guids across devices. This is tracked for PulseAudio at https://bugs.freedesktop.org/show_bug.cgi?id=90129. This is essentially a revert of systemd ed1b2d9fc7d5c5bfe2a67b0b8ff9e5ea8694268e.

2015-04-11rules: fix tests for removable stateMatthew Garrett
We only care about whether our direct parent is removable, not whether any further points up the tree are - the kernel will take care of policy for those itself. This enables autosuspend on devices where the root hub reports that its removable state is unknown.
2015-04-11udev: builtin-keyboard: add support for EVDEV_ABS_*Peter Hutterer
Parse properties in the form EVDEV_ABS_00="<min>:<max>:<res>:<fuzz>:<flat>" and apply them to the kernel device. Future processes that open that device will see the updated EV_ABS range. This is particularly useful for touchpads that don't provide a resolution in the kernel driver but can be fixed up through hwdb entries (e.g. bcm5974). All values in the property are optional, e.g. a string of "::45" is valid to set the resolution to 45. The order intentionally orders resolution before fuzz and flat despite it being the last element in the absinfo struct. The use-case for setting fuzz/flat is almost non-existent, resolution is probably the most common case we'll need. To avoid multiple hwdb invocations for the same device, replace the hwdb "keyboard:" prefix with "evdev:" and drop the separate 60-keyboard.rules file. The new 60-evdev.rules is called for all event nodes anyway, we don't need a separate rules file and second callout to the hwdb builtin.

2015-03-20rules: avoid 'device/' accessesDavid Herrmann
We should never access parents, as the sysfs hierarchy is in no way stable. Use KERNELS== etc. to match on a parent, then access it via $attr{} (which accesses the matching device, not the current device).
2015-03-20rules: fix input-name for keyboard rulesDavid Herrmann
We match on the evdev node, but only the parent has a "name" attribute. Use $attr{device/name} to access it. This is borked since 2013, I wonder how that ever worked? Maybe this will suddenly fix all the DMI-based key detections. Thanks to Peter Hutterer for catching this!

2015-03-16hwdb: merge atkbd into platform matchesDavid Herrmann
Currently, we always run hwdb 'keyboard:name:$attr{name}:$attr{[dmi/id]modalias}' as last step to match keyboards. Therefore, if nothing else matched so far, we still try the device-name+dmi combination. However, we have a special atkbd rule which is only run for atkbd as: hwdb 'keyboard:$attr{[dmi/id]modalias}' This is redundant, as we already pass the same information to hwdb in the last fallback step. This patch converts the hwdb "keyboard:dmi:*" matches to "keyboard:name:*:dmi:*" matches and drops the redundant rule.
