Kay Sievers 48a9b173e8 libudev: move to top-level directory 2009-06-08 21:36:06 +02:00
Kay Sievers bd75fddbcb require key names in uppercase 
Drop pretty expensive case-insensitive matching, and key names in
mixed or lowercase are not supported anyway.

Kay Sievers e14bdd88e9 libudev: monitor - add client socket filter for subsystem value 
Messages send back by the udev daemon to the netlink socket are
multiplexed by the kernel and delivered to multiple clients. The
clients can upload a socket filter to let the kernel drop messages
not belonging to a certain subsystem. This prevent needless wakeups
and message processing for users who are only interested in a
subset of available events.

Recent kernels allow untrusted users to listen to the netlink
messages.

The messages send by the udev daemon are versioned, to prevent any
custom software reading them without libudev. The message wire format
may change with any udev version update.

Alan Jenkins 4b09a2fc43 avoid leaking netlink socket fd to external programs 
The netlink socket is now used by udev event processes. We should take
care not to pass it to the programs they execute. This is the same way
the inotify fd was handled.

Alan Jenkins fa0e955a93 libudev: util - optimize path_encode() 
Since we already know the length, use memcpy() instead.
Measured 2% _user_ cpu time reduction on EeePC coldplug.
