Currently, when association enters SHUTDOWN state,the implementation will SACK any DATA first and then transmit the SHUTDOWN chunk. This is against the order required by 2960bis spec. SHUTDOWN must always be first, followed by SACK. This change forces this order and also enables bundling. Signed-off-by:

Currently, old flow cache entries remain valid even after a reload of SELinux policy. This patch increments the flow cache generation id on policy (re)loads so that flow cache entries are revalidated as needed. Thanks to Herbet Xu for pointing this out. See: http://marc.theaimsgroup.com/?l=linux-netdev&m=116841378704536&w=2 There's also a general issue as well as a solution proposed by David Miller for when flow_cache_genid wraps. I might be submitting a separate patch for that later. I request that this be applied to 2.6.20 since it's a security relevant fix. Signed-off-by:

When old flow cache entries that are not at the head of their chain trigger a transient security error they get unlinked along with all the entries preceding them in the chain. The preceding entries are not freed correctly. This patch fixes this by simply leaving the entry around. It's based on a suggestion by Venkat Yekkirala. Signed-off-by:

Any newly added irq handler may obviously make any old spurious irq status invalid, since the new handler may well be the thing that is supposed to handle any interrupts that came in. So just clear the statistics when adding handlers. Pointed-out-by:

while lock-profiling the -rt kernel i noticed weird contention during mmap-intense workloads, and the tracer showed the following gem, in one of our MM hotpaths: threaded-2771 1.... 65us : sys_munmap (sysenter_do_call) threaded-2771 1.... 66us : profile_munmap (sys_munmap) threaded-2771 1.... 66us : blocking_notifier_call_chain (profile_munmap) threaded-2771 1.... 66us : rt_down_read (blocking_notifier_call_chain) ouch! a global rw-semaphore taken in one of the most performance- sensitive codepaths of the kernel. And i dont even have oprofile enabled! All distro kernels have CONFIG_PROFILING enabled, so this scalability problem affects the majority of Linux users. The fix is to enhance blocking_notifier_call_chain() to only take the lock if there appears to be work on the call-chain. With this patch applied i get nicely saturated system, and much higher munmap performance, on SMP systems. And as a bonus this also fixes a similar scalability bottleneck in the thread-exit codepath: profile_task_exit() ... Signed-off-by:

A flag was recently added to the elevator code to avoid performing an unplug when reuests are being re-queued. The goal of this flag was to avoid a deep recursion that can occur when re-queueing requests after a SCSI device/host reset. See http://lkml.org/lkml/2006/5/17/254 However, that fix added the flag near the bottom of a case statement, where an earlier break (in an if statement) could transport one out of the case, without setting the flag. This patch sets the flag earlier in the case statement. I re-discovered the deep recursion recently during testing; I was told that it was a known problem, and the fix to it was in the kernel I was testing. Indeed it was ... but it didn't fix the bug. With the patch below, I no longer see the bug. Signed-off by: Linas Vepstas <linas@austin.ibm.com> Signed-off-by:

SMTC pseudo-interrupts between TCs are deferred and queued if the target TC is interrupt-inhibited (IXMT). In the first SMTC prototypes, these queued IPIs were serviced on return to user mode, or on entry into the kernel idle loop. The INSTANT_REPLAY option dispatches them as part of local_irq_restore() processing, which adds runtime overhead (hence the option to turn it off), but ensures that IPIs are handled promptly even under heavy I/O interrupt load.

This patch fixes a confusion reiserfs has for a long time. On release file operation reiserfs used to try to pack file data stored in last incomplete page of some files into metadata blocks. After packing the page got cleared with clear_page_dirty. It did not take into account that the page may be mmaped into other process's address space. Recent replacement for clear_page_dirty cancel_dirty_page found the confusion with sanity check that page has to be not mapped. The patch fixes the confusion by making reiserfs avoid tail packing if an inode was ever mmapped. reiserfs_mmap and reiserfs_file_release are serialized with mutex in reiserfs specific inode. reiserfs_mmap locks the mutex and sets a bit in reiserfs specific inode flags. reiserfs_file_release checks the bit having the mutex locked. If bit is set - tail packing is avoided. This eliminates a possibility that mmapped page gets cancel_page_dirty-ed. Signed-off-by:

Currently one can specify an arbitrary node mask to mbind that includes nodes not allowed. If that is done with an interleave policy then we will go around all the nodes. Those outside of the currently allowed cpuset will be redirected to the border nodes. Interleave will then create imbalances at the borders of the cpuset. This patch restricts the nodes to the currently allowed cpuset. The RFC for this patch was discussed at http://marc.theaimsgroup.com/?t=116793842100004&r=1&w=2Signed-off-by:

For large size DIO that needs multiple bio, one full page worth of data was lost at the boundary of bio's maximum sector or segment limits. After a bio is full and got submitted. The outer while (nbytes) { ... } loop will allocate a new bio and just march on to index into next page. It just forgets about the page that bio_add_page() rejected when previous bio is full. Fix it by put the rejected page back to pvec so we pick it up again for the next bio. Signed-off-by:Ken Chen <kenneth.w.chen@intel.com> Signed-off-by:

If a page is marked as dirty in the guest pte, set_pte_common() can set the writable bit on newly-instantiated shadow pte. This optimization avoids a write fault after the initial read fault. However, if a write fault instantiates the pte, fix_write_pf() incorrectly reports the fault as a guest page fault, and the guest oopses on what appears to be a correctly-mapped page. Fix is to detect the condition and only report a guest page fault on a user access to a kernel page. With the fix, a kvm guest can survive a whole night of running the kernel hacker's screensaver (make -j9 in a loop). Signed-off-by:

The various bit string instructions (bts, btc, etc.) fail to adjust the address correctly if the bit address is beyond BITS_PER_LONG. This bug creeped in as the emulator originally relied on cr2 to contain the memory address; however we now decode it from the mod r/m bits, and must adjust the offset to account for large bit indices. The patch is rather large because it switches src and dst decoding around, so that the bit index is available when decoding the memory address. This fixes workloads like the FC5 installer.

The kvm mmio read path looks like: 1. guest read faults 2. kvm emulates read, calls emulator_read_emulated() 3. fails as a read requires userspace help 4. exit to userspace 5. userspace emulates read, kvm sets vcpu->mmio_read_completed 6. re-enter guest, fault again 7. kvm emulates read, calls emulator_read_emulated() 8. succeeds as vcpu->mmio_read_emulated is set 9. instruction completes and guest is resumed A problem surfaces if the userspace exit (step 5) also requests an interrupt injection. In that case, the guest does not re-execute the original instruction, but the interrupt handler. The next time an mmio read is exectued (likely for a different address), step 3 will find vcpu->mmio_read_completed set and return the value read for the original instruction. The problem manifested itself in a few annoying ways: - little squares appear randomly on console when switching virtual terminals - ne2000 fails under nfs read load - rtl8139 complains about "pci errors" even though the device model is incapable of issuing them. Fix by skipping interrupt injection if an mmio read is pending. A better fix is to avoid re-entry into the guest, and re-emulating immediately instead. However that's a bit more complex.
