Changes

Since 042stab053.5:

• Rebased on 2.6.32-220.13.1.el6 RHEL6.2 kernel (security, bug fixes, and enhancements, see below)
• [procfs] make reading /proc/mounts consistent. Now we should get much less timeouts on CT stops (PSBM-12119)
• [ext4] online resize has been significantly enhanced (PSBM-12197)
• [timer] kmemsize leaks for 5457 has been fixed (PSBM-11885)
• [oom] now OOM can effectively struggle against fork bombs (PSBM-11920)
• 5 possible memory leaks were fixed in various places, found internally
• [bridge] kernel panic in bridge code in case NAT rules are configured improperly (PSBM-11782)
• [cpt] kernel panic in case a dead task gets into cpt image (PCLIN-30811)
• [cpt] we do align the size of cpt image. Online migration could fail due to tar which exits before reading the align tail. (PCLIN-30804)
• [fuse] FUSE improvements (write-back cache, AIO support, all off by default)
• [ploop] possible deadlock detected by lockdep fixed (PSBM-12210)
• [block] support for in-kernel direct aio added. (patch-set backports a few Zach Brown's patches from Chris Mason) (PCLIN-30658)
• [idle] add boot param intel_auto_demotion=force to forcibly enable intel auto demotion. For debug (PSBM-11477)
• [proc] kernel panic in /proc dentry put fixed (PSBM-12306)
• [ploop] add discard support
• [bridge] tcpdump shows incoming traffic in bridged veth CT (PCLIN-30814)
• [block] order of nested locking fixed in partition resize ioctl
• [ext4/ploop] preserve balloon_ino option on remount. Otherwise this option is dropped when some distrib scripts (unaware of ploop/balloon) remount root inside a CT. Use "balloon_ino=0" mount option if you need to really drop balloon. (#2225, PSBM-12337)
• [cpt] bypass limits on inotify files creation during CT checkpoint (PSBM-12475)
• [ploop] possible deadlock fixed
• [ploop] fixes for in-kernel grow of expanded images (#2226)
• [ploop] out-of-space error message has ben made more descriptive
• [raid] avoid deadlock on RAID1/RAID10 during resync recover
• [ubc] livelock in bdev cache allocation fixed (PSBM-12523)
• [cpt] a CT with tun device inside could not be migrated twice (PSBM-12502)
• [ploop] ENOSPC threshold defaults set: 2Gb for root, 4Gb for users. These thresholds can be changed via ploop.ko parameters
• [ploop] debug messages on error paths added
• [ubc] UB ram limit check skipped for __GFP_NOFAIL allocations. This prevents possible deadlocks (PSBM-12523)
• [ploop] max disk-space preallocation limited to 128MB independently on ploop cluster-block size. This reduces initial size of ploop image (PSBM-12546)
• [megaraid_sas] mask off flags in the ioctl path to prevent memory scribble with older MegaCLI versions (#2240)
• [atl1] kernel panic fixed in case of DMA errors
• [scheduler] warning added if huge IPI latency is detected (debug for PSBM-11683)
• [timer] kernel panic in timer interrupt in kexec on nodes with buggy BIOS fixed (PSBM-12579)
• [memory reclaimer] possibility to use sync writeback, make nodes much more responsive on high memory pressure (PSBM-11683, #2188)
• [oom] OOM priorities configuration has been reworked completely (PSBM-12263)
• [cgroups] kernel panic in devcgroup_seq_read() has been fixed (PSBM-12254)
• [cpt] task credentials fix
• [sheduler stat] /proc/uptime should now show correct idle time inside CT (PCLIN-30774)
• [fs] fix occasional NULL pointer dereference in show_vfsmnt() -> prepare_mnt_root_mangle() (PCLIN-30843, #2188#c62)
• [fs] fdatasync() optimization and statistics (/sys/fs/ext4/$dev{inflight_requests,optimized_flushes}) (PSBM-12094)
• [cpt] fix locking for netfilter conntrack expectations (PSBM-12691)
• [cpt] do not try to restore CT which can't be undumped (PSBM-12693, possibly #2244)
• [ploop] initial (incomplete) implementation of io_kaio - ploop io module based on in-kernel direct aio (PCLIN-30658)
• [ploop] optimization to more effectively merge requests by converting bio reqs to ploop reqs earlier
• fix sysinfo in containers: don't clean uptime, procs and loads (#2051)
• [cpufreq] fix memory leak in cpufreq_add_dev
• [ext4] check for zero length extent to prevent BUG_ON (bz.k.org #42859, PSBM-12241)
• [nfs] lockd: change ve in locks reclaimer thread (PSBM-12799)
• [ext4] Fix race leading to endless wait in ext4_ioend_wait() (PSBM-12831, PCLIN-30867, #2258)
• [ext4] Add fsync optimization statistics (PCLIN-30870)
• [nfs] kernel panic on a CT stop with NFS client inside fixed (PCLIN-30874)
• [cpt] online migration with tmpfs inside from kernels older than 54.1 failures fixed (PCLIN-30881)
• [fs] sync has been made per-container (was global) (PCLIN-30842)
• [vzquota] soft lockups on inode_lock have been fixed (PCLIN-30858, #2255)
