* ulimit: raise default hard ulimit on number of files to 4096Tim Gardner2011-05-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Apps are increasingly using more than 1024 file descriptors. See discussion in several distro bug trackers, e.g. BugLink: http://bugs.launchpad.net/bugs/663090 https://issues.rpath.com/browse/RPL-2054 You don't want to raise the default soft limit, since that might break apps that use select(), but it's safe to raise the default hard limit; that way, apps that know they need lots of file descriptors can raise their soft limit without needing root, and without user intervention. Ubuntu is doing this with a kernel change because they have a policy of not changing kernel defaults in userland. While 4096 might not be enough for *all* apps, it seems to be plenty for the apps I've seen lately that are unhappy with 1024.

* sched: SCHED_FIFO/SCHED_RR watchdog timerPeter Zijlstra2008-01-251-2/+3
| | | | | | | | | | | | | | | | Introduce a new rlimit that allows the user to set a runtime timeout on real-time tasks their slice. Once this limit is exceeded the task will receive SIGXCPU. So it measures runtime since the last sleep. Input and ideas by Thomas Gleixner and Lennart Poettering.

* sched: fix RLIMIT_CPU commentIngo Molnar2007-11-261-1/+1
| | | | | | | | | Devan Lippman noticed that the RLIMIT_CPU comment in resource.h is incorrect: the field is in seconds, not msecs. We used msecs in earlier versions of the patch but that got changed. Found-by: Devan Lippman <devan.lippman@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* [PATCH] nice and rt-prio rlimitsMatt Mackall2005-05-011-1/+6
| | | | | | | | | | | | | | | | | | | | Add a pair of rlimits for allowing non-root tasks to raise nice and rt priorities. Defaults to traditional behavior. Originally written by Chris Wright. The patch implements a simple rlimit ceiling for the RT (and nice) priorities a task can set. The rlimit defaults to 0, meaning no change in behavior by default. A value of 50 means RT priority levels 1-50 are allowed. A value of 100 means all 99 privilege levels from 1 to 99 are allowed. CAP_SYS_NICE is blanket permission. (akpm: see http://www.uwsg.iu.edu/hypermail/linux/kernel/0503.1/1921.html for tips on integrating this with PAM).

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+88
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
