This patch removes includes that are not used. The removals were found with
include-what-you-use which checks if any of the symbols from a header is
in use.
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.
include-what-you-use automatically does this and it makes finding
unnecessary harder to spot. The only content of poll.h is a include
of sys/poll.h so should be harmless.
After all it is now much more like strjoin() than strappend(). At the
same time, add support for NULL sentinels, even if they are normally not
necessary.
This is not exposed in the public API. We want to simplify the internal libudev-device API as much as possible
so that it will be simpler to rip the whole thing out in the future.
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.
This pulls out the hwdb managment from udevadm into an independent tool.
The old code is left in place for backwards compatibility, and easy of
testing, but all documentation is dropped to encourage use of the new
tool instead.
This has been requested repeatedly, so let's give it a go. We explicitly do not allow matching
on names that have already been changed (from a previous udev run, or otherwise), and matching
on unpredictable names (ethX) is discouraged (but not currently disallowed).
We also currently allow:
[Match]
Name=veth0
[Link]
Name=my-name0
SomeOtherSetting=true
Which means that the link file will be applied the first time it is invoked, but
not on subsequent invocations, which may be surprising.
This patch changes the naming scheme for sas disks. The original names used
disk's sas address and lun, the new scheme uses sas address of the
nearest expander (if available) and a phy id of the used connection.
If no expander is used, the phy id of hba phy is used.
Note that names that refer to RAID or other abstract devices are
unchanged.
Name in raid configuration:
hba_pci_address-sas-raid_sas_address-lunY-partZ
Name in expander bare disk configuration:
hba_pci_address-sas-expander_sas_address-phyX-lunY-partZ
Name format without expanders:
hba_pci_address-sas-phyX-lunY-partZ

Also accept '\r' as newline character.
This dropps warnings of the type:
invalid key/value pair in file /usr/lib/udev/rules.d/40-usb-media-players.rules
on line 26, starting at character 25 ('')
The current code would print the character following the first invalid
character.
Given an udev rules-file without a trailing newline we would otherwise print
garbage:
invalid key/value pair in file /usr/lib/udev/rules.d/40-usb-media-players.rules
on line 26, starting at character 25 ('m')
This is now changed to print
invalid key/value pair in file /usr/lib/udev/rules.d/40-usb-media-players.rules
on line 26, starting at character 25 ('')
(still not very good as printing \0 just gives the empty string)
Currently a property in the form of
FOO=bar
is stored as " FOO=bar", i.e. the property name contains a leading space.
That's quite hard to spot.
This patch discards all extra whitespaces but the first one which is required
by libudev's hwdb_add_property.
[zj: modify the check a bit]
