This is private configuraiton, so let's not pollute the namespace (and hence make Debian happy :) ).
|
|
This introduces a new key MACAddressPolicy.
The possible policies are 'persistent' and 'random'.
'persistent' will do nothing if the current address is the hardware address,
but if the hardware does not have an address (or another address is set for
whatever reason), we will generate an address which will be random, but
persistent between boots (based on machineid and persistent netif name).
'random' will do nothing if the kernel already set a random address, otherwise
it will generate a random one and use that instead.
This patch sets MACAddressPolicy=persistent in the default .link file.
|
|
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 adds support for setting the mac address, name and mtu.
Example:
[Link]
MTU=1450
MACAddress=98:76:54:32:10:ab
Name=wireless0
|
|
This adds support for setting the link speed, duplex and WakeOnLan
settings.
Example:
[Link]
SpeedMBytes=100
Duplex=half
WakeOnLan=magic
|
|
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

This matches the bcma support in the network device naming.
Eventually wa want to make sure ID_PATH is equivalent to ID_NET_NAME_PATH,
so we never need to match on the latter.
|
|
I want to use this from a bulitin in a subsequent patch.
|
|
Not that it makes a difference in this builtin, but otherwise /etc/udev/udev.conf is not respected.
|
|
Always use our own macros, and name all our own macros the same style.

Since the invention of read-only memory, write-only memory has been
considered deprecated. Where appropriate, either make use of the
value, or avoid writing it, to make it clear that it is not used.
|

bInterfaceSubClass == 5 is not a "floppy"; just identify the obsolete
QIC-157 interface as "generic".

Always cache the results, and bypass low-level security calls when the
respective subsystem is not enabled.

Set some_transport = true to prevent scm devices from being ignored.

This reverts commit 47e737dc13bf4251ae5a2249ec29b34503ed92e1 - it
introduced a use-after-free. The only way the code would get simpler
is with a cleanup function, but eh, not worth it for just this one
bit.

systemd-udevd[6260]: invalid key/value pair in file /usr/lib/udev/rules.d/60-ffado.rules on line 46,starting at character 84 ('#')

A regression introduced when we moved to systemd's logging is that the only
way to adjust the log-level of the udev daemon is via the env var, kernel
commandline or the commandline.
This reintroduces support for specifying this in the configuration file.

Based on a patch by Kay Sievers.
A tag is exported at boot as a symlinks to the device node in the folder
/run/udev/static_node-tags/<tagname>/, if the device node exists.
These tags are cleaned up by udevadm info --cleanup-db, but are otherwise
never removed.

Revert commit 90fc91d0065 again. There is no 900XC3 model, that's 900X3C and
already covered by the 900X3* match.

This allows to specify:

As of kmod v14, it is possible to export the static node information from
/lib/modules/`uname -r`/modules.devname in tmpfiles.d(5) format.
Use this functionality to let systemd-tmpfilesd create the static device nodes
at boot, and drop the functionality from systemd-udevd.
As an effect of this we can move from systemd-udevd to systemd-tmpfiles-setup-dev:
* the conditional CAP_MKNOD (replaced by checking if /sys is mounted rw)
* ordering before local-fs-pre.target (see 89d09e1b5c65a2d97840f682e0932c8bb499f166)

If key mappings are defined in the kernel driver, userspace must
not overwrite them. If something is wrong with the kernel-provided
values, the kernel driver shold be fixed instead.
Some of the matches are not the input device name but the kernel
driver name, which will not match anything.
|
|
There are no such strings for input devices in the kernel.

With Linux 3.9 (commit a935eaecef2b209ad661dadabb4e32b7c9a9b924), the
Asus keyboard driver has changed to be more compliant to the symbol
signification. This has led to some issues with udev. In particular,
the XF86TouchpadToggle (a Fn key) does not work anymore on Asus X52J.
I found another similar patch which does not seem to have been ever
submitted/merged:
