This fixes a oops due to a double list add when adding a reject PDU for iscsit_allocate_iovecs allocation failures. The cmd has already been added to the conn_cmd_list in iscsit_setup_scsi_cmd, so this has us call iscsit_reject_cmd. Note that for ERL0 the reject PDU is not actually sent, so this patch is not completely tested. Just verified we do not oops. The problem is the add reject functions return -1 which is returned all the way up to iscsi_target_rx_thread which for ERL0 will drop the connection.

Remove the end address checking for flushda function. We need to flush each address line for flushda instruction, from start to end address. This is because flushda instruction only flush the cache if tag and line fields are matched. Change to use ldwio instruction (bypass cache) to load the instruction that causing trap. Our interest is the actual instruction that executed by the processor, this should be uncached. Note, EA address might be an userspace cached address. Signed-off-by: NLey Foon Tan <lftan@altera.com>

Unlike most (all?) other copies from user space, kernel module loading is almost unlimited in size. So we do a potentially huge "copy_from_user()" when we copy the module data from user space to the kernel buffer, which can be a latency concern when preemption is disabled (or voluntary). Also, because 'copy_from_user()' clears the tail of the kernel buffer on failures, even a *failed* copy can end up wasting a lot of time. Normally neither of these are concerns in real life, but they do trigger when doing stress-testing with trinity. Running in a VM seems to add its own overheadm causing trinity module load testing to even trigger the watchdog. The simple fix is to just chunk up the module loading, so that it never tries to copy insanely big areas in one go. That bounds the latency, and also the amount of (unnecessarily, in this case) cleared memory for the failure case.

The rule for 'copy_from_user()' is that it zeroes the remaining kernel buffer even when the copy fails halfway, just to make sure that we don't leave uninitialized kernel memory around. Because even if we check for errors, some kernel buffers stay around after thge copy (think page cache). However, the x86-64 logic for user copies uses a copy_user_generic() function for all the cases, that set the "zerorest" flag for any fault on the source buffer. Which meant that it didn't just try to clear the kernel buffer after a failure in copy_from_user(), it also tried to clear the destination user buffer for the "copy_in_user()" case. Not only is that pointless, it also means that the clearing code has to worry about the tail clearing taking page faults for the user buffer case. Which is just stupid, since that case shouldn't happen in the first place. Get rid of the whole "zerorest" thing entirely, and instead just check if the destination is in kernel space or not. And then just use memset() to clear the tail of the kernel buffer if necessary. Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

Some BIOS version of Fujitsu Lifebook T731 seems to set up the headphone pin (0x21) without the assoc number 0x0f while it's set only to the output on the docking port (0x1a). With the recent commit [03ad6a8c: ALSA: hda - Fix "PCM" name being used on one DAC when there are two DACs], this resulted in the weird mixer element mapping where the headphone on the laptop is assigned as a shared volume with the speaker and the docking port is assigned as an individual headphone. This patch improves the situation by correcting the headphone pin config to the more appropriate value.

Booting a v3.18 or newer Xen domU kernel with PCI devices passed through results in an oops (this is a 32-bit 3.13.11 dom0 with a 64-bit 4.4.0 hypervisor and 32-bit domU): BUG: unable to handle kernel paging request at 0030303e IP: [<c06ed0e6>] acpi_ns_validate_handle+0x12/0x1a Call Trace: [<c06eda4d>] ? acpi_evaluate_object+0x31/0x1fc [<c06b78e1>] ? pci_get_hp_params+0x111/0x4e0 [<c0407bc7>] ? xen_force_evtchn_callback+0x17/0x30 [<c04085fb>] ? xen_restore_fl_direct_reloc+0x4/0x4 [<c0699d34>] ? pci_device_add+0x24/0x450 Don't look for ACPI configuration information if ACPI has been disabled. I don't think this is the best fix, because we can boot plain Linux (no Xen) with "acpi=off", and we don't need this check in pci_get_hp_params(). There should be a better fix that would make Xen domU work the same way. The domU kernel has ACPI support but it has no AML. There should be a way to initialize the ACPI data structures so things fail gracefully rather than oopsing. This is an interim fix to address the regression.

Currently when a process accesses a hugetlb range protected with PROTNONE, unexpected COWs are triggered, which finally puts the hugetlb subsystem into a broken/uncontrollable state, where for example h->resv_huge_pages is subtracted too much and wraps around to a very large number, and the free hugepage pool is no longer maintainable.

It was not reproducible with the machines I had used to justify the original patch because large numbers of CPUs are required. When pressure is high enough, the cache line is bouncing between CPUs trying to acquire the lock and the holder of the lock adjusting free lists. The intention was that the acquirer of the lock would automatically have the cache line holding the free lists but according to Huang, this is not a universal win. One possibility is to move the zone lock to its own cache line but it increases the size of the zone. This patch moves the lock to the other end of the free lists where they do not contend under high pressure. It does mean the page allocator paths now require more cache lines but Huang reports that it restores performance to previous levels on large machines %stddev %change %stddev \ | \ 84568 \261 1% +94.3% 164280 \261 1% aim7.jobs-per-min 2881944 \261 2% -35.1% 1870386 \261 8% aim7.time.voluntary_context_switches 681 \261 1% -3.4% 658 \261 0% aim7.time.user_time 5538139 \261 0% -12.1% 4867884 \261 0% aim7.time.involuntary_context_switches 44174 \261 1% -46.0% 23848 \261 1% aim7.time.system_time 426 \261 1% -48.4% 219 \261 1% aim7.time.elapsed_time 426 \261 1% -48.4% 219 \261 1% aim7.time.elapsed_time.max 468 \261 1% -43.1% 266 \261 2% uptime.boot Signed-off-by: NMel Gorman <mgorman@suse.de> Reported-by: NHuang Ying <ying.huang@intel.com> Tested-by: NHuang Ying <ying.huang@intel.com> Acked-by: NDavid Rientjes <rientjes@google.com> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

This reverts commit 89baaa57. Dirty page throttling should be sufficient for us in the general case so there is no need to use __GFP_MEMALLOC - it would be needed only in the swap-over-rbd case, which we currently don't support. (It would probably take approximately the commit that is being reverted to add that support, but we would also need the "swap" option to distinguish from the general case and make sure swap ceph_client-s aren't shared with anything else.) See ceph-devel threads [1] and [2] for the details of why enabling pfmemalloc reserves for all cases is a bad thing. On top of potential system lockups related to drained emergency reserves, this turned out to cause ceph lockups in case peers are on the same host and communicating via loopback due to sk_filter() dropping pfmemalloc skbs on the receiving side because the receiving loopback socket is not tagged with SOCK_MEMALLOC.

Pull networking fixes from David Miller: 1) In TCP, don't register an FRTO for cumulatively ACK'd data that was previously SACK'd, from Neal Cardwell. 2) Need to hold RNL mutex in ipv4 multicast code namespace cleanup, from Cong WANG. 3) Similarly we have to hold RNL mutex for fib_rules_unregister(), also from Cong WANG. 4) Revert and rework netns nsid allocation fix, from Nicolas Dichtel. 5) When we encapsulate for a tunnel device, skb->sk still points to the user socket. So this leads to cases where we retraverse the ipv4/ipv6 output path with skb->sk being of some other address family (f.e. AF_PACKET). This can cause things to crash since the ipv4 output path is dereferencing an AF_PACKET socket as if it were an ipv4 one. The short term fix for 'net' and -stable is to elide these socket checks once we've entered an encapsulation sequence by testing xmit_recursion. Longer term we have a better solution wherein we pass the tunnel's socket down through the output paths, but that is way too invasive for 'net' and -stable. From Hannes Frederic Sowa. 6) l2tp_init() failure path forgets to unregister per-net ops, from Cong WANG. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: net/mlx4_core: Fix error message deprecation for ConnectX-2 cards net: dsa: fix filling routing table from OF description l2tp: unregister l2tp_net_ops on failure path mvneta: dont call mvneta_adjust_link() manually ipv6: protect skb->sk accesses from recursive dereference inside the stack netns: don't allocate an id for dead netns Revert "netns: don't clear nsid too early on removal" ip6mr: call del_timer_sync() in ip6mr_free_table() net: move fib_rules_unregister() under rtnl lock ipv4: take rtnl_lock and mark mrt table as freed on namespace cleanup tcp: fix FRTO undo on cumulative ACK of SACKed range xen-netfront: transmit fully GSO-sized packets

Commit 1daa4303 ("net/mlx4_core: Deprecate error message at ConnectX-2 cards startup to debug") did the deprecation only for port 1 of the card. Need to deprecate for port 2 as well.

According to description in 'include/net/dsa.h', in cascade switches configurations where there are more than one interconnected devices, 'rtable' array in 'dsa_chip_data' structure is used to indicate which port on this switch should be used to send packets to that are destined for corresponding switch. However, dsa_of_setup_routing_table() fills 'rtable' with port numbers of the _target_ switch, but not current one. This commit removes redundant devicetree parsing and adds needed port number as a function argument. So dsa_of_setup_routing_table() now just looks for target switch number by parsing parent of 'link' device node. To remove possible misunderstandings with the way of determining target switch number, a corresponding comment was added to the source code and to the DSA device tree bindings documentation file. This was tested on a custom board with two Marvell 88E6095 switches with following corresponding routing tables: { -1, 10 } and { 8, -1 }.
