If a fault in the kernel leads to an unexpected protection fault whilst in a code path which holds mmap_sem we will deadlock in do_page_fault() while trying to classify the fault. By carefully testing the source of the fault we can detect and OOPS on the vast majority of these, greatly enhancing diagnosis of such bugs. Signed-off-by:

Jeremy Katz of Red Hat reported that his iSeries machine would not boot with 2.6.7 based kernels. It appears that with the inclusion of Paul Mackerras' patch "Optimize exception/syscall entry/exit" a small previous patch got reverted. Here is that patch again. The lack of this patch does not stop all iSeries machines booting, but it does stop some. Signed-off-by:

ext2_setattr() drops the inode_setattr() return value on the floor. This is very bad - I/O errors during truncate are lost. The patch changes ext2_setattr() so that we no longer call ext2_acl_chmod() if inode_setattr(), which is what ext3 does. Signed-off-by:

We permanently hold the i_sem of swapfiles so that nobody can addidentally ftruncate them, causing subsequent filesystem destruction. Problem is, it's fairly easy for things like backup applications to get stuck onthe swapfile, sleeping until someone does a swapoff. So take all that out again and add a new S_SWAPFILE inode flag. Test that in the truncate path and refuse to truncate an in-use swapfile. Synchronisation between swapon and truncate is via i_sem. Signed-off-by:

ext3_direct_io_get_blocks() is misinterpreting the return value from ext3_journal_extend(), and is consequently running out of buffer credits and going BUG on tremendously large direct-io writes. Fix that up. Also, I note that the really large direct-io writes can hold a transaction open for the entire duration, which can be minutes. This violates ext3's attempt to commit data at regular intervals. Fix that up by looking at the transaction state: if it's T_LOCKED, shut off the current handle so the pending commit can complete.

Here's a patch to reorder timer_tsc.c so gcc 3.4 does not fail to inline and thus fix the warning "arch/i386/kernel/timers/timer_tsc.c:30: warning: inlining failed in call to 'cpufreq_delayed_get': function body not available" Signed-off-by:

Vladimir Saveliev reported anon_vma_unlink list_del BUG (LKML 24 June). His testing is still in progress, but we believe it comes from a nasty locking deficiency I introduced in 2.6.7's anon_vma_prepare. Andrea's original anon_vma_prepare was fine, it needed no anon_vma lock because it was always linking a freshly allocated structure; but my find_mergeable enhancement let it adopt a neighbouring anon_vma, which of course needs locking against a racing linkage from another mm - which the earlier adjust_vma fix seems to have made more likely. Does anon_vma->lock nest inside or outside page_table_lock? Inside, but that's not obvious without a lock ordering list: instead of listing the order here, update the list in filemap.c; but a separate patch because that's less urgent and more likely to get wrong or provoke controversy. (Could do it with anon_vma lock after dropping page_table_lock, but a long comment explaining why some code is safe suggests it's not.) Signed-off-by:

This introduces meaningfull labels instead of .L1234, meaning code is readable, kills alignment where unneccessary, and kills TLB flush that was only pure paranoia (and slows it down a lot on emulated systems). Signed-off-by:

From: Herve Eychenne <rv@eychenne.org> Clean up the script. This also makes it two times faster. (Thanks to Herve Eychenne.) - moved variable definitions to the top, for easier configuration - the script contains bashisms, so make it /bin/bash - use sed -e'...' -e '...' instead of sed | sed - avoid subshells: () changed to {} - various other minor optimizations and improvements Signed-off-by: -

From: Andy Whitcroft <apw@shadowen.org> This patch eliminates the false hole which can form between ZONE_NORMAL and ZONE_HIGHMEM. This is most easily seen when 4g/4g split is enabled, but it's always broken, and we just happen not to hit it most of the time. Basically, the patch changes the allocation of the numa remaps regions (the source of the holes) such that they officially fall within VMALLOC space, where they belong. Tested in -mjb for a couple of months, and again against 2.6.7-mm1. Signed-off-by:

Hit a kernel oops on 2.6.7 kernel when doing direct I/O to hugetlb page. The destructor of compound page was moved into page->mapping since 2.6.6. It got interfered with set_page_dirty() for hugetlb page: an O_DIRECT read into first tail page of the compound page will fool set_page_dirty() to deference page->mapping->a_ops and then kernel oops. Patch to fix the oops. We do just like what bio_set_pages_dirty() does. Signed-off-by:

Right now the kernel detects the sysadmin trying to set the iocharset of vfat to UTF8 and prevents this with an error. While I can see that this is not recommended, enforcing this is policy that probably doesn't belong in the kernel. The patch below makes this situation a warning and a recommendation instead of a strong blockage. https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=126641 is an example of a sysadmin disliking this policy enforcement.

SELinux should just drop out the socket and netfilter hooks when that is disabled. The problem was introduced because of the fine-grained netlink patches, which made the selinux_netlink_send/recv hook functions depend on CONFIG_SECURITY_NETWORK but the netlink_send/recv hooks themselves are not dependent on it. Need to move selinux_netlink_send/recv back out of the conditional block, and provide a static inline stub for selinux_nlmsg_perm if CONFIG_SECURITY_NETWORK is not defined. Signed-off-by:
