2009-07-13udevd: handle SIGCHLD before the worker event messageKay Sievers
We may need to handle SIGCHLD before the queued worker message. The last reference, from the SIGCHLD or the worker message will clean up the worker context. In case we receive an unexpected SIGCHLD with an error, we let the event fail and clean up the worker context.
2009-07-11udevd: make sure a worker finishes event handling before exitingKay Sievers
Persistent network rules write out new rules files. When rules change, we need to kill all workers to update the in-memory copy of the rules. We need to make sure, that a worker finshes its work for all device messages it has accepted, before it exits after a SIGTERM from the main process.
2009-07-08udevadm: info - add space after R:, A:, W: on database exportKay Sievers
<zzam> kay: udevadmin info -e prints all lines with a space after the :, but the W: line <kay> zzam: yeah, seems so, and the R: and the A: <zzam> yeah

2009-06-10udevadm: info -revert "accept --query without argument"Kay Sievers
Getopt is too dumb, the optional argument breaks "udevadm -q symlink".

2009-06-04udevd: close netlink socket in worker and set cloexecKay Sievers
2009-06-04udevd: convert to event worker processesKay Sievers
Event processes now get re-used after they handled an event. This reduces pressure on the CPU significantly because cloned event processes no longer cause page faults in the main daemon. After the events have settled, the no longer needed worker processes get killed.

2009-05-28udevd: queue-export - fix crashAlan Jenkins
The math in skip_to() was the wrong way round and allocated a variable size array on the stack with a massively negative size. Signed-off-by: Alan Jenkins <alan-jenkins@tuffmail.co.uk>

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>

2009-05-14OWNER/GROUP: fix if logicScott James Remnant
The introduction of the --resolve-names=early/never code introduced a bug to the OWNER/GROUP lookup. Previously if the name had contained $, lookup would have been performed later; after the patch, the key ended up being ignored!
