From: Dave Johnson <djohnson+linux-kernel@sw.starentnetworks.com> sendmsg()/recvmsg() syscalls from o32/n32 apps to a 64bit kernel will cause a kernel memory leak if iov_len > UIO_FASTIOV for each syscall! This is because both sys_sendmsg() and verify_compat_iovec() kmalloc a new iovec structure. Only the one from sys_sendmsg() is free'ed. I wrote a simple test program to confirm this after identifying the problem: http://davej.org/programs/testsendmsg.c Note that the below fix will break solaris_sendmsg()/solaris_recvmsg() as it also calls verify_compat_iovec() but expects it to malloc internally. [ I fixed that. -DaveM ] Signed-off-by:

Remove new configuration API from i2o_config The API-patch is still available from the I2O website (which is mentioned in the kernel config now). It is removed because it creates a new binary sysfs-attribute, which doesn't have the limitiation of 4k. Expect for the Adaptec controllers, which has a limitation in the hardware this attribute doesn't make sense anywhere else. Until the sysfs API provides an attribute which doesn't buffer (like firmware) and let access to at least 64k blocks i provide a separate patch... (akpm: basically, this API was introduced post-2.6.12 and Markus wants to pull it out before 2.6.13). Signed-off-by:

Fix possible cpuset_sem ABBA deadlock if 'notify_on_release' set. For a particular usage pattern, creating and destroying cpusets fairly frequently using notify_on_release, on a very large system, this deadlock can be seen every few days. If you are not using the cpuset notify_on_release feature, you will never see this deadlock. The existing code, on task exit (or cpuset deletion) did: get cpuset_sem if cpuset marked notify_on_release and is ready to release: compute cpuset path relative to /dev/cpuset mount point call_usermodehelper() forks /sbin/cpuset_release_agent with path drop cpuset_sem Unfortunately, the fork in call_usermodehelper can allocate memory, and allocating memory can require cpuset_sem, if the mems_generation values changed in the interim. This results in an ABBA deadlock, trying to obtain cpuset_sem when it is already held by the current task. To fix this, I put the cpuset path (which must be computed while holding cpuset_sem) in a temporary buffer, to be used in the call_usermodehelper call of /sbin/cpuset_release_agent only _after_ dropping cpuset_sem. So the new logic is: get cpuset_sem if cpuset marked notify_on_release and is ready to release: compute cpuset path relative to /dev/cpuset mount point stash path in kmalloc'd buffer drop cpuset_sem call_usermodehelper() forks /sbin/cpuset_release_agent with path free path The sharp eyed reader might notice that this patch does not contain any calls to kmalloc. The existing code in the check_for_release() routine was already kmalloc'ing a buffer to hold the cpuset path. In the old code, it just held the buffer for a few lines, over the cpuset_release_agent() call that in turn invoked call_usermodehelper(). In the new code, with the application of this patch, it returns that buffer via the new char **ppathbuf parameter, for later use and freeing in cpuset_release_agent(), which is called after cpuset_sem is dropped. Whereas the old code has just one call to cpuset_release_agent(), right in the check_for_release() routine, the new code has three calls to cpuset_release_agent(), from the various places that a cpuset can be released. This patch has been build and booted on SN2, and passed a stress test that previously hit the deadlock within a few seconds. Signed-off-by:Paul Jackson <pj@sgi.com> Signed-off-by:

The patch below unhooks fsnotify from vfs_unlink & vfs_rmdir. It introduces two new fsnotify calls, that are hooked in at the dcache level. This not only more closely matches how the VFS layer works, it also avoids the problem with locking and inode lifetimes. The two functions are - fsnotify_nameremove -- called when a directory entry is going away. It notifies the PARENT of the deletion. This is called from d_delete(). - inoderemove -- called when the files inode itself is going away. It notifies the inode that is being deleted. This is called from dentry_iput(). Signed-off-by:

With the introduction of 'rustynat' in 2.6.11, the old tricks of preventing NAT of 'untracked' connections (e.g. NOTRACK target in 'raw' table) are no longer sufficient. The ip_conntrack_untracked.status |= IPS_NAT_DONE_MASK effectively prevents iteration of the 'nat' table, but doesn't prevent nat_packet() to be executed. Since nr_manips is gone in 'rustynat', nat_packet() now implicitly thinks that it has to do NAT on the packet. This patch fixes that problem by explicitly checking for ip_conntrack_untracked in ip_nat_fn(). Signed-off-by:

Reported by:Vincent Fortier (Bugzilla Bug 4768) "At boot time the screen appears moved to the mid right portion of the actual video pannel making the end of the line appears at the left edge... It simply looks like moved half way to the right" His particular hardware has a display with an unusual dimension (1920x1200) but unfortunately has no EDID block. None of the entries in the global mode database is correct for this particular display, and it particularly has difficulty scaling up 640x480 (the default startup mode of nvidiafb) to 1920x1200 which causes the above described problem. 1, Add 1920x1200 to the global mode database. 2. Let nvidiafb base the startup mode from the flatpanel dimensions only if the EDID block is absent, no boot mode parameter is specified by the user, and a flatpanel/LCD display is attached.

I'm resending this patch, because I still believe it's the correct fix. Tested before/after applying the patch with a test application available from: http://www.inf.bme.hu/~mszeredi/nstest.c Bind mount from a foreign namespace results in an un-removable mount. The reason is that mnt->mnt_namespace is copied from the old mount in clone_mnt(). Because of this check_mnt() in sys_umount() will fail. The solution is to set mnt->mnt_namespace to current->namespace in clone_mnt(). clone_mnt() is either called from do_loopback() or copy_tree(). copy_tree() is called from do_loopback() or copy_namespace(). When called (directly or indirectly) from do_loopback(), always current->namspace is being modified: check_mnt(nd->mnt). So setting mnt->mnt_namespace to current->namspace is the right thing to do. When called from copy_namespace(), the setting of mnt_namespace is irrelevant, since mnt_namespace is reset later in that function for all copied mounts. Jamie said: This patch is correct. The old code was buggy for more fundamental and serious reason: it broke the invariant that a tree of vfsmnts all have the same value of mnt_namespace (and the same for the mnt_list list).
