2006-07-03[PATCH] ZVC/zone_reclaim: Leave 1% of unmapped pagecache pages for file I/OChristoph Lameter
It turns out that it is advantageous to leave a small portion of unmapped file backed pages if all of a zone's pages (or almost all pages) are allocated and so the page allocator has to go off-node. This allows recently used file I/O buffers to stay on the node and reduces the times that zone reclaim is invoked if file I/O occurs when we run out of memory in a zone. The problem is that zone reclaim runs too frequently when the page cache is used for file I/O (read write and therefore unmapped pages!) alone and we have almost all pages of the zone allocated. Zone reclaim may remove 32 unmapped pages. File I/O will use these pages for the next read/write requests and the unmapped pages increase. After the zone has filled up again zone reclaim will remove it again after only 32 pages. This cycle is too inefficient and there are potentially too many zone reclaim cycles. With the 1% boundary we may still remove all unmapped pages for file I/O in zone reclaim pass. However. it will take a large number of read and writes to get back to 1% again where we trigger zone reclaim again. The zone reclaim 2.6.16/17 does not show this behavior because we have a 30 second timeout.

lock_queue was getting called essentially twice in a row and was continually incrementing the mm_count ref count, thus causing a memory leak. Dinakar Guniguntala provided a proper fix for the problem that simply grabs the spinlock for the hash bucket queue rather than calling lock_queue. The second time we do a queue_lock in futex_lock_pi, we really only need to take the hash bucket lock.

2006-07-01[PATCH] add rule filterkeyAmy Griffis
Add support for a rule key, which can be used to tie audit records to audit rules. This is useful when a watched file is accessed through a link or symlink, as well as for general audit log analysis. Because this patch uses a string key instead of an integer key, there is a bit of extra overhead to do the kstrdup() when a rule fires. However, we're also allocating memory for the audit record buffer, so it's probably not that significant. I went ahead with a string key because it seems more user-friendly. Note that the user must ensure that filterkeys are unique. The kernel only checks for duplicate rules. Signed-off-by: Amy Griffis <amy.griffis@hpd.com>

2006-06-30[PATCH] cond_resched() fixAndrew Morton
Fix a bug identified by Zou Nan hai <nanhai.zou@intel.com>: If the system is in state SYSTEM_BOOTING, and need_resched() is true, cond_resched() returns true even though it didn't reschedule. Consequently need_resched() remains true and JBD locks up. Fix that by teaching cond_resched() to only return true if it really did call schedule(). cond_resched_lock() and cond_resched_softirq() have a problem too. If we're in SYSTEM_BOOTING state and need_resched() is true, these functions will drop the lock and will then try to call schedule(), but the SYSTEM_BOOTING state will prevent schedule() from being called. So on return, need_resched() will still be true, but cond_resched_lock() has to return 1 to tell the caller that the lock was dropped. The caller will probably lock up. Bottom line: if these functions dropped the lock, they _must_ call schedule() to clear need_resched(). Make it so. Also, uninline __cond_resched(). It's largeish, and slowpath.

2006-06-30[PATCH] zoned vm counters: zone_reclaim: remove ↵Christoph Lameter
/proc/sys/vm/zone_reclaim_interval The zone_reclaim_interval was necessary because we were not able to determine how many unmapped pages exist in a zone. Therefore we had to scan in intervals to figure out if any pages were unmapped. With the zoned counters and NR_ANON_PAGES we now know the number of pagecache pages and the number of mapped pages in a zone. So we can simply skip the reclaim if there is an insufficient number of unmapped pages. We use SWAP_CLUSTER_MAX as the boundary. Drop all support for /proc/sys/vm/zone_reclaim_interval.

2006-06-29[NETLINK]: Encapsulate eff_cap usage within security framework.Darrel Goeddel
This patch encapsulates the usage of eff_cap (in netlink_skb_params) within the security framework by extending security_netlink_recv to include a required capability parameter and converting all direct usage of eff_caps outside of the lsm modules to use the interface. It also updates the SELinux implementation of the security_netlink_send and security_netlink_recv hooks to take advantage of the sid in the netlink_skb_params struct. This also enables SELinux to perform auditing of netlink capability checks. Please apply, for 2.6.18 if possible.
