9e9e333b937[PATCH] grsecurity: TPE feature This patch is a part of big grsecure-2.1.10 patch.This patch doesn't contain virtualization support, and source code looks like original grsecure source as much as possible. V2 - added TPE check in mmap()/mprotect() V3 - removed exec_file; added grsec_lock feature

a4f772f2135[PATCH] mangle devname in /proc/mounts only for OVZ specific simfs We used to hide devname in /proc/mounts to prevent leaking HN-node information to the VE. Actually only VZ specifics should be hidden, i.e. simfs root. All other information can be shown as is.And the fix is actually required for NFS. its umount scripts goes crazy when can't read real NFS server mount information. Bug #87637

1a76bc71fb0[CPT] checkpointing sysv msg queuesCheckpointing of sysv msg queues. Allows to live migrate DB2.
Alexey KuznetsovAlexey Kuznetsov
05177753e16[CPT] changes to core required to checkpoint sysv msg queues1. "Standard" set, like SHM and SEM: sysvipc_walk_msg, sysvipc_setup_msg, additional arqument to newque() to pass ipc id. 2. Two new exports: sysv_msg_store, sysv_msg_load. The structure is enough weird to deal with it inside CPT.

89b051b2f69[PATCH] don't mmap zero pages for /dev/zero in advance In current implementation mmap_zero() immedeately mmaps zero page to the whole /dev/zero vma and thus allocates/pollutes all pte's. This is actually not required and can be dangerous if vma is very big.For CPT we do not need such "optimization", as we can set vm_ops on this vma and return zero page on demand. Bug #91769

9d1a588f524[PATCH] fix dump_trace() when called from NMI For x86_64 architecture NMI interrupt handler (do_NMI) uses exception stack.

1f4e9f9dbda[PATCH] CPT: fix restore of process start timeDue to stupid misprint processes start_time were restored incorrectly. When we restore start_time of process we should sum up value from image with VE start time. During checkpoint we save to the image relative process start_time (process start_time - VE start_time).

55c9604c098[PATCH] fix for cond_resched() fix: remove wrong WARN_ON(1) WARN_ON(1) is illegal, since when we return from cond_resched()->schedule() we have preempt_count = PREEMPT_ACTIVE, and if we have still current->need_resched flag set we can get to cond_resched() again from schedule()->reacquire_kernel_lock()->cond_resched() and thus this WARN_ON(1) gets triggered.Bug #92140

260e37d8aff[PATCH] cond_resched_lock() doesn't work in 2.6.18 When CONFIG_PREEMPT=n, cond_resched_lock() and cond_resched_softirq() don't work, since they check for preempt_count to be sane, but this counter is not tracked w/o preemption and is always 0.So the fix is: - ignore preempt count when CONFIG_PREEMPT=n - plus if we want to check preempt_count in CONFIG_PREEMPT=y case (just to be on the safe side), we need to account lock_kernel() effect on preempt_count correctly. Bug #91012

Right now the only thing that tries to do so is skb_copy_and_csum_datagram_iovec.

aa5edcac4e8[PATCH] net: allow SIOCSIFFLAGS in dev_ioctl() This patch allows ioctl SIOCSIFFLAGS from VE on PF_INET6 socket.In old VEs (with redhat-6.2) ifconfig calls ioctl() on IPv6 socket, while tries to make venet UP inside VE. And fails. Since this ioctl is prohibited in dev_ioctl(). Newer ifconfig's call this ioctl() on IPv4 socket and thus end up with inet_ioctl(). Bug #91248

1d913299bbf[PATCH] uncharge pids from kmemsize a bit earlier When charged with generic slab charger pids hold the beancounter and may pin it to memory after VE is stopped. The proposal is to charge/uncharge pids manually letting them live longer than the beancounter. This is OK, since the only reason (in rhel5 kernel) they can do so is that proc inodes hold them. However, this is not a big deal, as inodes...Potential fix for bug #83891 BTW, patch named diff-ve-proc-hash-pid-dentries-20070516 may be dropped from the list.

5c22dd08adf[PATCH] improve shrink_dcache_sb() This patch makes shrink_dcache_sb consistent with dentry pruning policy.On the first pass we iterate over dentry unused list and prepare some dentries for removal. However, since the existing code moves evicted dentries to the beginning of the LRU it can happen that fresh dentries from other superblocks will be inserted *before* our dentries. This can result in significant slowdown of shrink_dcache_sb(). Moreover, for virtual filesystems like unionfs which can cal...
