[ Upstream commit 59b9997b ] This reverts commit 8a83a00b. It causes regressions for S390 devices, because it does an unconditional DST drop on SKBs for vlans and the QETH device needs the neighbour entry hung off the DST for certain things on transmit. Arnd can't remember exactly why he even needed this change. Conflicts: drivers/net/macvlan.c net/8021q/vlan_dev.c net/core/dev.c Signed-off-by:

[ Upstream commit d4b11335 ] commit c57b5468 (pktgen: fix crash at module unload) did a very poor job with list primitives. 1) list_splice() arguments were in the wrong order 2) list_splice(list, head) has undefined behavior if head is not initialized. 3) We should use the list_splice_init() variant to clear pktgen_threads list.

[ Upstream commit c51ce497 ] An application may call connect() to disconnect a socket using an address with family AF_UNSPEC. The L2TP IP sockets were not handling this case when the socket is not bound and an attempt to connect() using AF_UNSPEC in such cases would result in an oops. This patch addresses the problem by protecting the sk_prot->disconnect() call against trying to unhash the socket before it is bound. The patch also adds more checks that the sockaddr supplied to bind() and connect() calls is valid.

[ Upstream commit 0c183379 ] Since commit ad0081e4 "ipv6: Fragment locally generated tunnel-mode IPSec6 packets as needed" the fragment of packets is incorrect. because tunnel mode needs IPsec headers and trailer for all fragments, while on transport mode it is sufficient to add the headers to the first fragment and the trailer to the last. so modify mtu and maxfraglen base on ipsec mode and if fragment is first or last. with my test,it work well(every fragment's size is the mtu) and does not trigger slow fragment path. Changes from v1: though optimization, mtu_prev and maxfraglen_prev can be delete. replace xfrm mode codes with dst_entry's new frag DST_XFRM_TUNNEL. add fuction ip6_append_data_mtu to make codes clearer.

commit 2e8b5063 upstream. I was trying to backport the following commit to RHEL-6 From 0cea73465cd22373c5cd43a3edd25fbd4bb532ef Mon Sep 17 00:00:00 2001 From: Oliver Neukum <oliver@neukum.org> Date: Wed, 21 Sep 2011 11:37:15 +0200 Subject: [PATCH] btusb: add device entry for Broadcom SoftSailing and noticed it wasn't working on an HP Elitebook. Looking into the patch I noticed a very subtle typo in the ids. The patch has '0x05ac' instead of '0x0a5c'. A snippet of the lsusb -v output also shows this: Bus 002 Device 003: ID 0a5c:21e1 Broadcom Corp. Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 2.00 bDeviceClass 255 Vendor Specific Class bDeviceSubClass 1 bDeviceProtocol 1 bMaxPacketSize0 64 idVendor 0x0a5c Broadcom Corp. idProduct 0x21e1 bcdDevice 1.12 iManufacturer 1 Broadcom Corp iProduct 2 BCM20702A0 iSerial 3 60D819F0338C bNumConfigurations 1 Looking at other Broadcom ids, the fix matches them whereas the original patch matches Apple's ids. Tested on an HP Elitebook 8760w. The btusb binds and the userspace stuff loads correctly. Cc: Oliver Neukum <oliver@neukum.org> Signed-off-by:

commit 59d92bfa upstream. We've simply ignored this, which isn't too great. With this, interlaced 1080i works on my HDMI screen connected through sdvo. For no apparent reason anything else still doesn't work as it should. While at it, give these magic numbers in the dtd proper names and add a comment that they match with EDID detailed timings. v2: Actually use the right bit for interlaced. Tested-by:

commit b4bd8ad9 upstream. DMA support has finally made its way to the top of the TODO list, having realised that a Geode using MMIO can't keep up with two ADSL2+ lines each running at 21Mb/s. This patch fixes a couple of bugs in the DMA support in the driver, so once the corresponding FPGA update is complete and tested everything should work properly. We weren't storing the currently-transmitting skb, so we were never unmapping it and never freeing/popping it when the TX was done. And the addition of pci_set_master() is fairly self-explanatory.

commit 2f649c1f upstream. commit 5e185581 Author: James Bottomley <JBottomley@Parallels.com> [PARISC] fix PA1.1 oops on boot Didn't quite fix the crash on boot. It moved it from PA1.1 processors to PA2.0 narrow kernels. The final fix is to make sure the [id]tlb_miss_20 paths also work. Even on narrow systems, these paths require using the wide instructions becuase the tlb insertion format is wide. Fix this by conditioning the dep[wd],z on whether we're being called from _11 or _20[w] paths. Tested-by:

commit ed5fb247 upstream. In certain configurations, the resulting kernel becomes too large to boot because the linker places the long branch stubs for the merged .text section at the very start of the image. As a result, the initial transfer of control jumps to an unexpected location. Fix this by placing the head text in a separate section so the stubs for .text are not at the start of the image.

While traversing the linked list of open file handles, if the identfied file handle is invalid, a reopen is attempted and if it fails, we resume traversing where we stopped and cifs can oops while accessing invalid next element, for list might have changed. So mark the invalid file handle and attempt reopen if no valid file handle is found in rest of the list. If reopen fails, move the invalid file handle to the end of the list and start traversing the list again from the begining. Repeat this four times before giving up and returning an error if file reopen keeps failing. Signed-off-by:

commit 882dde8e upstream. When BT traffic load changes from its previous state, a new LQ command needs to be sent down to the firmware. This needs to be done only once per change. The state variable that keeps track of this change is last_bt_traffic_load. However, it was not being updated when the change had been handled. Not updating this variable was causing a flood of advanced BT config commands to be sent to the firmware. Fix this. Signed-off-by:

Only archs with 64bit large pmd_t and 32bit unsigned long should be affected. With THP enabled the barrier() in pmd_none_or_trans_huge_or_clear_bad() would partly hide the bug when the pmd transition from none to stable, by forcing a re-read of the *pmd in pmd_offset_map_lock, but when THP is enabled a new set of problem arises by the fact could then transition freely in any of the none, pmd_trans_huge or pmd_trans_stable states. So making the barrier in pmd_none_or_trans_huge_or_clear_bad() unconditional isn't good idea and it would be a flakey solution. This should be fully fixed by introducing a pmd_read_atomic that reads the pmd in order with THP disabled, or by reading the pmd atomically with cmpxchg8b with THP enabled. Luckily this new race condition only triggers in the places that must already be covered by pmd_none_or_trans_huge_or_clear_bad() so the fix is localized there but this bug is not related to THP. NOTE: this can trigger on x86 32bit systems with PAE enabled with more than 4G of ram, otherwise the high part of the pmd will never risk to be truncated because it would be zero at all times, in turn so hiding the SMP race. This bug was discovered and fully debugged by Ulrich, quote: ---- [..] pmd_none_or_trans_huge_or_clear_bad() loads the content of edx and eax. 496 static inline int pmd_none_or_trans_huge_or_clear_bad(pmd_t *pmd) 497 { 498 /* depend on compiler for an atomic pmd read */ 499 pmd_t pmdval = *pmd; // edi = pmd pointer 0xc0507a74 <sys_mincore+548>: mov 0x8(%esp),%edi ... // edx = PTE page table high address 0xc0507a84 <sys_mincore+564>: mov 0x4(%edi),%edx ... // eax = PTE page table low address 0xc0507a8e <sys_mincore+574>: mov (%edi),%eax [..] Please note that the PMD is not read atomically.

Hence, the above machine code is prone to the following race. - The PMD entry {high|low} is 0x0000000000000000. The "mov" at 0xc0507a84 loads 0x00000000 into edx. - A page fault (on another CPU) sneaks in between the two "mov" instructions and instantiates the PMD. - The PMD entry {high|low} is now 0x00000003fda38067. The "mov" at 0xc0507a8e loads 0xfda38067 into eax. ---- Reported-by:

commit e4898273 upstream. Commit 64574746 ("vmscan: detect mapped file pages used only once") made mapped pages have another round in inactive list because they might be just short lived and so we could consider them again next time. This heuristic helps to reduce pressure on the active list with a streaming IO worklods. This patch fixes a regression introduced by this commit for heavy shmem based workloads because unlike Anon pages, which are excluded from this heuristic because they are usually long lived, shmem pages are handled as a regular page cache. This doesn't work quite well, unfortunately, if the workload is mostly backed by shmem (in memory database sitting on 80% of memory) with a streaming IO in the background (backup - up to 20% of memory). Anon inactive list is full of (dirty) shmem pages when watermarks are hit. Shmem pages are kept in the inactive list (they are referenced) in the first round and it is hard to reclaim anything else so we reach lower scanning priorities very quickly which leads to an excessive swap out. Let's fix this by excluding all swap backed pages (they tend to be long lived wrt. the regular page cache anyway) from used-once heuristic and rather activate them if they are referenced. The customer's workload is shmem backed database (80% of RAM) and they are measuring transactions/s with an IO in the background (20%). Transactions touch more or less random rows in the table. The transaction rate fell by a factor of 3 (in the worst case) because of commit 64574746. This patch restores the previous numbers. Signed-off-by:

commit b7e94a16 upstream. block congestion control doesn't have any concept of fairness across multiple queues. This means that if SCSI reports the host as busy in the queue congestion control it can result in an unfair starvation situation in dm-mp if there are multiple multipath devices on the same host. For example: http://www.redhat.com/archives/dm-devel/2012-May/msg00123.html The fix for this is to report only the sdev busy state (and ignore the host busy state) in the block congestion control call back. The host is still congested, but the SCSI subsystem will sort out the congestion in a fair way because it knows the relation between the queues and the host.

commit 1ff2f403 upstream. Commit c7510859 Author: Rafael J. Wysocki <rjw@sisk.pl> Date: Sun Apr 12 20:06:56 2009 +0200 PM/Hibernate: Wait for SCSI devices scan to complete during resume Broke the scsi_wait_scan module in 2.6.30. Apparently debian still uses it so fix it and backport to stable before removing it in 3.6. The breakage is caused because the function template in include/scsi/scsi_scan.h is defined to be a nop unless SCSI is built in. That means that in the modular case (which is every distro), the scsi_wait_scan module does a simple async_synchronize_full() instead of waiting for scans. Signed-off-by:

commit 435a7ef5 upstream. We can't be holding the mmap_sem while calling flush_cache_user_range because the flush can fault. If we fault on a user address, the page fault handler will try to take mmap_sem again. Since both places acquire the read lock, most of the time it succeeds. However, if another thread tries to acquire the write lock on the mmap_sem (e.g. mmap) in between the call to flush_cache_user_range and the fault, the down_read in do_page_fault will deadlock.
