2009-06-05udevd: use enum instead of char in struct declarationKay Sievers
2009-05-21udevd: implement a more efficient queue file formatAlan Jenkins
Directory lookups show up in profiling. The queue files are responsible for a large proportion of file-related system calls in udev coldplug. Instead of creating a file for each event, append their details to a log file. The file is periodically rebuilt (garbage-collected) to prevent it from growing indefinitely. This single queue file replaces both the queue directory and the uevent_seqnum file. On desktop systems the file tends not to grow beyond one page. So it should also save a small amount of memory in tmpfs. Tests on a running EeePC indicate average savings of 5% *udevd* cpu time as measured by oprofile. __link_path_walk is reduced from 1.5% to 1.3%. It is not completely clear where the rest of the gains come from. In tests running ~400 events, the queue file is rebuilt about 5 times. Signed-off-by: Alan Jenkins <alan-jenkins@tuffmail.co.uk>

2009-04-22libudev: monitor - add client socket filter for subsystem valueKay Sievers
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.
2009-03-29"UDEV_MONITOR_KERNEL/UDEV" -> "kernel/udev"Kay Sievers
2009-03-29send monitor events back to netlink socketKay Sievers
Instead of of our own private monitor socket, we send the processed event back to our netlink socket, to the multicast group 2 -- so any number of users can listen to udev events, just like they can listen to kernel emitted events on group 1.

"Hello world!" linked against libselinux parses /proc/mounts and whatever else on startup, even when the lib is not needed at all. Not funny! Get rid of that thing where it's not absolutely needed.
