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.
|
|
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.
|
|
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).

Currently used to tag devices in the new Lenovo *50 series and the X1 Carbon
3rd. These laptops re-introduced the physical trackpoint buttons that were
missing from the *40 series but those buttons are now wired up to the
touchpad.
The touchpad now sends BTN_0, BTN_1 and BTN_2 for the trackpoint. The same
button codes were used in older touchpads that had dedicated scroll up/down
buttons. Input drivers need to work around this and thus know what they're
dealing with.
For the previous gen we introduced INPUT_PROP_TOPBUTTONPAD in the kernel, but
the resulting mess showed that these per-device quirks should really live in
userspace.
The list currently includes the X1 Carbon 3rd PNPID, others will be added as
get to know which PNPID they have.

Ejecting a CD with the hardware drive button only causes a change uevent, but
the device node stays around (just without a medium). Pick up these uevents and
mark the device as SYSTEMD_READY=0 on ejection, so that systemd stops the
device unit and consequently all mount units on it.
On media insertion, mark the device as SYSTEMD_READY=1 again.

There is no reason to keep both separated. We want to avoid API specific
tools and instead keep generic terms like 'input'.

This rule is only run on tablet/touchscreen devices, and extracts their size
in millimeters, as it can be found out through their struct input_absinfo.
The first usecase is exporting device size from tablets/touchscreens. This
may be useful to separate policy and application at the time of mapping
these devices to the available outputs in windowing environments that don't
offer that information as readily (eg. Wayland). This way the compositor can
stay deterministic, and the mix-and-match heuristics are performed outside.
Conceivably, size/resolution information can be changed through EVIOCSABS
anywhere else, but we're only interested in values prior to any calibration,
this rule is thus only run on "add", and no tracking of changes is performed.
This should only remain a problem if calibration were automatically applied
by an earlier udev rule (read: don't).
v2: Folded rationale into commit log, made a builtin, set properties
on device nodes themselves
v3: Use inline function instead of macro for mm. size calculation,
use DECIMAL_STR_MAX, other code style issues
v4: Made rule more selective
v5: Minor style issues, renamed to a more generic builtin, refined
rule further.

Pointer acceleration for relative input devices (mice, trackballs, etc.)
applies to the deltas of the device. Alas, those deltas have no physical
reference point - a delta of 10 may be caused by a large movement of a
low-dpi mouse or by a minute movement of a high-dpi mouse.
Which makes pointer acceleration a bit useless and high-dpi devices
essentially unusable.
In an ideal world, we could read the DPI from the device directly and work
with that. In the world we actually live in, we need to compile this list
manually. This patch introduces the database, with the usual match formats
and a single property to be set on a device: MOUSE_DPI
That is either a single value for most mice, or a list of values for mice
that can change resolution at runtime. The exact format is detailed in the
hwdb file.
Note that we're explicitly overshooting the requirements we have for
libinput atm. Frequency could be detected in software and we don't
actually use the list of multiple resolutions (because we can't detect
when they change anyway). However, we might as well collect those values
from the get-go, adding/modifying what will eventually amount to hundreds
of entries is a bit cumbersome.
Note: we rely on the input_id builtin to tag us as mouse first, ordering
of the rules is important.
(David: fixed up typos and moved hwdb file into ./hwdb/)

blueness> poettering, was there a reason for not removing
50-firmware.rules when you nuked userland firmware
loading?
Followup for v216-119-gbe2ea723b1.

SYSTEMD_READY is currently set to 0 for all loop devices (loop[0-9]*)
that do not have a backing_file. Partitioned loop devices (ex. loop0p1),
however, are matched by this rule and excluded by systemd even though
they are active devices.
This change adds an additional check to the rule, ensuring that only
top level loop devices (loop[0-9]+$) are excluded from systemd.

Re-apply the keymaps when "udevadm trigger" is called. Hooking into
"add" only would just remove all keymap content from the udev database
instead of applying the new config.

Update comment to be a bit more specific.
Change match to blacklist the serial number of the broken devices
instead of whitelisting the serial number of the fixed devices.
This allows to do something useful with the serial number in the
future.

Add the first 3270 terminal device that is associated with the Linux preferred
console to the list of virtualization consoles. This is required to
automatically start a getty if the conmode=3270 kernel parameter is specified
for Linux on z/VM instances. Note that a queued upstream patch also enable
the 3270 terminal device if it is associated with the Linux preferred console.
How
To successfully start agetty on a 3270 terminal, a change in the agetty
parameter order is required. Previously, agetty would started like this:
/sbin/agetty --keep-baud 3270/tty1 115200,38400,9600 TERM
The agetty program interprets the "3270/tty1" as baud rate and fails to start
with the "bad speed: 3270/tty1" error message. Fixing this in agetty is more
complex rather than reordering the command line parameters like this:
/sbin/agetty --keep-baud 115200,38400,9600 3270/tty1 TERM
According to agetty sources and "agetty --help", agetty accepts the "tty",
"baudrate tty", and "tty baudrate" specifications.
P.S. The "tty: Set correct tty name in 'active' sysfs attribute" introduces
a change to display the terminal device which is associated with the
Linux preferred console. This change helps to let systemd handle this
particular case only. Without the changes of this commit, no additional
3270 terminal device can be managed by systemd.

Before it was placed in /dev/disk/by-id, which makes it a bit too much
API. However, it's mostly an implementation detail for now, hence move
it out of the stable block device dir.

Check existence of loop/backing_file in sysfs and mark loop devices with
SYSTEMD_READY if missing. Such loop files is uninitialized and it's not
ready for use yet (there's no file attached).

udev seems to have a race condition with swapon to see which can open
/dev/zram0 first, causing swapon to fail. Seems to be most noticeable
on arm devices one out of every 7 times or something.

Ensure to start getty programs on all essential system consoles on Linux on
System z. Add these essential devices to the list of virtualization_consoles
to always generate getty configurations.
For the sake of completion, the list of essential consoles is:
/dev/sclp_line0 - Operating system messages applet (LPAR)
/dev/ttysclp0 - Integrated ASCII console applet (z/VM and LPAR)
/dev/ttyS0 - Already handled by systemd (3215 console on z/VM)
/dev/hvc0 - Already handled by systemd (IUCV HVC terminal on z/VM)
Depending on the environment, z/VM or LPAR, only a subset of these terminals
are available.
See also RH BZ 860158[1] "Cannot login via Operating System Console into RHEL7
instance installed on a LPAR". This bugzilla actually blocks the installation
of Linux on System z instances in LPAR mode.

We don't need any GOTO, if we merge all matches into a single line.

The path_id-builtin provides useful unique aliases for DRM devices. If we
want to configure DRM render-nodes for compositors, we want to avoid
storing the whole sys-path in configuration files. Hence, allow users to
store the short PATH_ID instead.
Load path_id-builtin unconditionally on DRM devices now to always provide
this alias.

This introduces a new key NamePolicy, which takes an ordered list of naming
policies. The first successful one is applide. If all fail the value of Name
(if any) is used.
The possible policies are 'onboard', 'slot', 'path' and 'mac'.
This patch introduces a default link file, which replaces the equivalent udev
rule.

This tool applies hardware specific settings to network devices before they
are announced via libudev.
Settings that will probably eventually be supported are MTU, Speed,
DuplexMode, WakeOnLan, MACAddress, MACAddressPolicy (e.g., 'hardware',
'synthetic' or 'random'), Name and NamePolicy (replacing our current
interface naming logic). This patch only introduces support for
Description, as a proof of concept.
Some of these settings may later be overriden by a network management
daemon/script. However, these tools should always listen and wait on libudev
before touching a device (listening on netlink is not enough). This is no
different from how things used to be, as we always supported changing the
network interface name from udev rules, which does not work if someone
has already started using it.
The tool is configured by .link files in /etc/net/links/ (with the usual
overriding logic in /run and /lib). The first (in lexicographical order)
matching .link file is applied to a given device, and all others are ignored.
The .link files contain a [Match] section with (currently) the keys
MACAddress, Driver, Type (see DEVTYPE in udevadm info) and Path (this
matches on the stable device path as exposed as ID_PATH, and not the
unstable DEVPATH). A .link file matches a given device if all of the
specified keys do. Currently the keys are treated as plain strings,
but some limited globbing may later be added to the keys where it
makes sense.
Example:
/etc/net/links/50-wireless.link
[Match]
MACAddress=98:f2:e4:42:c6:92
Path=pci-0000:02:00.0-bcma-0
Type=wlan
[Link]
Description=The wireless link

Changing the default MODE= for the group accessi, but not specifying
a GROUP= does not provide anything.
It disables the default logic that the mode switches to 0660 as soon
as a GROUP= is specifed, which make custom rules uneccesarily complicated.

Devices should show up in systemd regardless whether the user invoked
"udevadm trigger" or not. Before this change some devices might have
suddenly disappeared due issuing that command.
|
|
Since the kernel no longer exposes a large number of "dead" loop devices
it is OK to expose them now in systemd, so let's do that. This has the
benefit that mount dependencies on loop devices start to work.
|
|
Much like for rfkill devices we should provide some stability regarding
enumeration order, hence include the stable bits of the device path in
the file name we store settings under.
|
|
Let's include the stable device path for the rfkill devices in the name
of the file we store the rfkill state in, so that we have some stability
regarding enumeration order.

This works analogous to the existing backlight and random seed services
