a701623 | Hugh Dickins | 29 January 2010, 17:46:34 UTC | mm: fix migratetype bug which slowed swapping After memory pressure has forced it to dip into the reserves, 2.6.32's 5f8dcc21211a3d4e3a7a5ca366b469fb88117f61 "page-allocator: split per-cpu list into one-list-per-migrate-type" has been returning MIGRATE_RESERVE pages to the MIGRATE_MOVABLE free_list: in some sense depleting reserves. Fix that in the most straightforward way (which, considering the overheads of alternative approaches, is Mel's preference): the right migratetype is already in page_private(page), but free_pcppages_bulk() wasn't using it. How did this bug show up? As a 20% slowdown in my tmpfs loop kbuild swapping tests, on PowerMac G5 with SLUB allocator. Bisecting to that commit was easy, but explaining the magnitude of the slowdown not easy. The same effect appears, but much less markedly, with SLAB, and even less markedly on other machines (the PowerMac divides into fewer zones than x86, I think that may be a factor). We guess that lumpy reclaim of short-lived high-order pages is implicated in some way, and probably this bug has been tickling a poor decision somewhere in page reclaim. But instrumentation hasn't told me much, I've run out of time and imagination to determine exactly what's going on, and shouldn't hold up the fix any longer: it's valid, and might even fix other misbehaviours.

Peter Anvin | 29 January 2010, 06:14:43 UTC | x86: get rid of the insane TIF_ABI_PENDING bit Now that the previous commit made it possible to do the personality setting at the point of no return, we do just that for ELF binaries. And suddenly all the reasons for that insane TIF_ABI_PENDING bit go away, and we can just make SET_PERSONALITY() just do the obvious thing for a 32-bit compat process.

221af7f | Linus Torvalds | 29 January 2010, 06:14:42 UTC | Split 'flush_old_exec' into two functions 'flush_old_exec()' is the point of no return when doing an execve(), and it is pretty badly misnamed. It doesn't just flush the old executable environment, it also starts up the new one. Which is very inconvenient for things like setting up the new personality, because we want the new personality to affect the starting of the new environment, but at the same time we do _not_ want the new personality to take effect if flushing the old one fails. As a result, the x86-64 '32-bit' personality is actually done using this insane "I'm going to change the ABI, but I haven't done it yet" bit (TIF_ABI_PENDING), with SET_PERSONALITY() not actually setting the personality, but just the "pending" bit, so that "flush_thread()" can do the actual personality magic. This patch in no way changes any of that insanity, but it does split the 'flush_old_exec()' function up into a preparatory part that can fail (still called flush_old_exec()), and a new part that will actually set up the new exec environment (setup_new_exec()). All callers are changed to trivially comply with the new world order. Signed-off-by: H.

035fe03 | Josef Bacik | 27 January 2010, 02:09:38 UTC | Btrfs: check total number of devices when removing missing If you have a disk failure in RAID1 and then add a new disk to the array, and then try to remove the missing volume, it will fail. The reason is the sanity check only looks at the total number of rw devices, which is just 2 because we have 2 good disks and 1 bad one. Instead check the total number of devices in the array to make sure we can actually remove the device. Tested this with a failed disk setup and with this test we can now run btrfs-vol -r missing /mount/point and it works fine.

So instead if we are in degraded mode, return 0 so we can go ahead and allocate stuff. Without this patch all of the block groups in a RAID1 setup will end up read-only, which will mean we can't add new disks to the array since we won't be able to make allocations.

a555f81 | Chris Mason | 28 January 2010, 21:18:15 UTC | Btrfs: Add mount -o compress-force The default btrfs mount -o compress mode will quickly back off compressing a file if it notices that compression does not reduce the size of the data being written. This can save considerable CPU because all future writes to the file go through uncompressed. But some files are both very large and have mixed data stored in them. In that case, we want to add the ability to always try compressing data before writing it. This commit adds mount -o compress-force. A later commit will add a new inode flag that does the same thing.

Using a greater number without IRQ sharing requires reading platform-specific registers. On such platforms, reading the IntCtl register to determine which interrupt corresponds to a timer interrupt will not work. On MIPSR2 systems there is a solution - the TI bit in the Cause register, specifically indicates that a timer interrupt has occured. This patch uses that bit to detect interrupts for MIPSR2 processors, which may be expected to work regardless of how the timer interrupt may be routed in the hardware.

9c4a6fc | Alexander Clouter | 20 January 2010, 20:50:07 UTC | MIPS: Fix vmlinuz build for 32bit-only math shells POSIX requires $((<expression>)) arithmetic in sh only to have long arithmetic so on 32-bit sh binaries might do only 32-bit arithmetic but the arithmetic done in arch/mips/boot/compressed/Makefile needs 64-bit. I play with the AR7 platform, so VMLINUX_LOAD_ADDRESS is 0xffffffff94100000, and for an example 4MiB kernel VMLINUZ_LOAD_ADDRESS is made out to be: ---- alex@berk:~$ bash -c 'printf "%x\n" $((0xffffffff94100000 + 0x400000))' ffffffff94500000 alex@berk:~$ dash -c 'printf "%x\n" $((0xffffffff94100000 + 0x400000))' 80000000003fffff ---- The former is obviously correct whilst the later breaks things royally. Fortunately working with only the lower 32bit's works for both bash and dash: ---- $ bash -c 'printf "%x\n" $((0x94100000 + 0x400000))' 94500000 $ dash -c 'printf "%x\n" $((0x94100000 + 0x400000))' 94500000 ---- So, we can split the original 64bit string to two parts, and only calculate the low 32bit part, which is big enough (1GiB kernel sizes anyone?) for a normal Linux kernel image file, now, we calculate the VMLINUZ_LOAD_ADDRESS like this: 1. if present, append top 32bit of VMLINUX_LOAD_ADDRESS" as a prefix 2. get the sum of the low 32bit of VMLINUX_LOAD_ADDRESS + VMLINUX_SIZE This patch fixes vmlinuz kernel builds on systems where only a 32bit-only math shell is available.

With luck, this merely prevents video reception. With only a little less luck, the machine crashes. We use the same workaround here as with TSB43AB22/A: Switch off the dual buffer capability flag and use packet-per-buffer IR DMA instead. Another possible workaround would be to limit the coherent DMA mask to 31 bits. In Linux 2.6.33, this change serves effectively only as documentation since dual buffer mode is not used for any controller anymore. But somebody might want to re-enable it in the future to make use of features of dual buffer DMA that are not available in packet-per-buffer mode. In Linux 2.6.32 and older, this update is vital for anyone with this controller, more than 2 GB RAM, a 64 bit kernel, and FireWire video or audio applications.

0531b2a | Linus Torvalds | 27 January 2010, 17:20:03 UTC | mm: add new 'read_cache_page_gfp()' helper function It's a simplified 'read_cache_page()' which takes a page allocation flag, so that different paths can control how aggressive the memory allocations are that populate a address space. In particular, the intel GPU object mapping code wants to be able to do a certain amount of own internal memory management by automatically shrinking the address space when memory starts getting tight. This allows it to dynamically use different memory allocation policies on a per-allocation basis, rather than depend on the (static) address space gfp policy. The actual new function is a one-liner, but re-organizing the helper functions to the point where you can do this with a single line of code is what most of the patch is all about.

We need to copy such payloads for each registered userspace client and free the copies according to the lifetime rules of non-FCP client request resources. (This could possibly be optimized by reference counts instead of copies.) The presently only kernelspace driver which listens for FCP requests, firedtv, was not affected because it already copies FCP frames into an own buffer before returning to firewire-core's FCP handler dispatcher.

e300839 | Stefan Richter | 24 January 2010, 13:47:02 UTC | firewire: core: add_descriptor size check Presently, firewire-core only checks whether descriptors that are to be added by userspace drivers to the local node's config ROM do not exceed a size of 256 quadlets. However, the sum of the bare minimum ROM plus all descriptors (from firewire-core, from firewire-net, from userspace) must not exceed 256 quadlets. Otherwise, the bounds of a statically allocated buffer will be overwritten. If the kernel survives that, firewire-core will subsequently be unable to parse the local node's config ROM. (Note, userspace drivers can add descriptors only through device files of local nodes. These are usually only accessible by root, unlike device files of remote nodes which may be accessible to lesser privileged users.) Therefore add a test which takes the actual present and required ROM size into account for all descriptors of kernelspace and userspace drivers.

39d3215 | Herbert Xu | 25 January 2010, 23:51:01 UTC | virtio_net: Make delayed refill more reliable I have seen RX stalls on a machine that experienced a suspected OOM. After the stall, the RX buffer is empty on the guest side and there are exactly 16 entries available on the host side. As the number of entries is less than that required by a maximal skb, the host cannot proceed. The guest did not have a refill job scheduled. My diagnosis is that an OOM had occured, with the delayed refill job scheduled. The job was able to allocate at least one skb, but not enough to overcome the minimum required by the host to proceed. As the refill job would only reschedule itself if it failed completely to allocate any skbs, this would lead to an RX stall. The following patch removes this stall possibility by always rescheduling the refill job until the ring is totally refilled. Testing has shown that the RX stall no longer occurs whereas previously it would occur within a day.

bd1f46d | Andrew Patterson | 22 January 2010, 21:06:53 UTC | PCI: fix nested spinlock hang in aer_inject The aer_inject module hangs in aer_inject() when checking the device's error masks. The hang is due to a recursive use of the aer_inject lock. The aer_inject() routine grabs the lock while processing the error and then calls pci_read_config_dword to read the masks. The pci_read_config_dword routine is earlier overridden by pci_read_aer, which among other things, grabs the aer_inject lock. Fixed by moving the pci_read_config_dword calls to read the masks to before the lock is taken.

Static code analysis revealed a potential problem: the intercept_funcs jump table was defined to contain (0x48 >> 2) entries, but we only checked for code > 0x48 which would cause an off-by-one array overflow if code == 0x48.

The vcpu can pick up the IRR and inject the interrupt before setting the TMR, and perhaps even EOI it, causing incorrect behaviour. The race is really insignificant since it can only occur on the first interrupt (usually following interrupts will not change TMR), but it's better closed than open.
