2017-02-09sctp: drop unnecessary __packed from some stream reconf structuresXin Long
commit 85c727b59483 ("sctp: drop __packed from almost all SCTP structures") has removed __packed from almost all SCTP structures. But there still are three structures where it should be dropped. This patch is to remove it from some stream reconf structures. Signed-off-by: Xin Long <lucien.xin@gmail.com> Acked-by: Marcelo Ricardo Leitner <marcelo.leitner@gmail.com> Signed-off-by: David S.

Pull SCSI target fixes from Nicholas Bellinger: "This target series for v4.10 contains fixes which address a few long-standing bugs that DATERA's QA + automation teams have uncovered while putting v4.1.y target code into production usage. We've been running the top three in our nightly automated regression runs for the last two months, and the COMPARE_AND_WRITE fix Mr. Gary Guo has been manually verifying against a four node ESX cluster this past week. Note all of them have CC' stable tags. Summary: - Fix a bug with ESX EXTENDED_COPY + SAM_STAT_RESERVATION_CONFLICT status, where target_core_xcopy.c logic was incorrectly returning SAM_STAT_CHECK_CONDITION for all non SAM_STAT_GOOD cases (Nixon Vincent) - Fix a TMR LUN_RESET hung task bug while other in-flight TMRs are being aborted, before the new one had been dispatched into tmr_wq (Rob Millner) - Fix a long standing double free OOPs, where a dynamically generated 'demo-mode' NodeACL has multiple sessions associated with it, and the /sys/kernel/config/target/$FABRIC/$WWN/ subsequently disables demo-mode, but never converts the dynamic ACL into a explicit ACL (Rob Millner) - Fix a long standing reference leak with ESX VAAI COMPARE_AND_WRITE when the second phase WRITE COMMIT command fails, resulting in CHECK_CONDITION response never being sent and se_cmd->cmd_kref never reaching zero (Gary Guo) Beyond these items on v4.1.y we've reproduced, fixed, and run through our regression test suite using iscsi-target exports, there are two additional outstanding list items: - Remove a >= v4.2 RCU conversion BUG_ON that would trigger when dynamic node NodeACLs where being converted to explicit NodeACLs. The patch drops the BUG_ON to follow how pre RCU conversion worked for this special case (Benjamin Estrabaud) - Add ibmvscsis target_core_fabric_ops->max_data_sg_nent assignment to match what IBM's Virtual SCSI hypervisor is already enforcing at transport layer.

2017-02-09Input: psmouse - add a custom serio protocol to send extra informationBenjamin Tissoires
The tracksticks on the Lenovo thinkpads have their buttons connected through the touchpad device. We already fixed that in synaptics.c, but when we switch the device into RMI4 mode to have proper support, the pass-through functionality can't deal with them easily. We add a new PS/2 flag and protocol designed for psmouse. The RMI4 F03 pass-through can then emit a special set of commands to notify psmouse the state of the buttons. This patch implements the protocol in psmouse, while an other will do the same for rmi4-f03.

The nl80211_nan_dual_band_conf enumeration doesn't make much sense. The default value is assigned to a bit, which makes it weird if the default bit and other bits are set at the same time. To improve this, get rid of NL80211_NAN_BAND_DEFAULT and add a wiphy configuration to let the drivers define which bands are supported. This is exposed to the userspace, which then can make a decision on which band(s) to use. Additionally, rename all "dual_band" elements to "bands", to make things clearer.

ACPICA commit b59347d0b8b676cb555fe8da5cad08fcd4eeb0d3 The following commit cleans up compiler specific inclusions: Commit: 9fa1cebdbfff3db8953cebca8ee327d75edefc40 Subject: ACPICA: OSL: Cleanup the inclusion order of the compiler-specific headers But breaks one thing due to the following old issue: Buidling Linux kernel with Intel compiler originally depends on acgcc.h not acintel.h. So after making Intel compiler build working in ACPICA upstream by correctly using acintel.h, it becomes unable to build Linux kernel using Intel compiler as there is no acintel.h in the kernel source tree. This patch releases acintel.h to Linux kernel and fixes its inclusion in acenv.h.

2017-02-08cpumask: use nr_cpumask_bits for parsing functionsTejun Heo
Commit 513e3d2d11c9 ("cpumask: always use nr_cpu_ids in formatting and parsing functions") converted both cpumask printing and parsing functions to use nr_cpu_ids instead of nr_cpumask_bits. While this was okay for the printing functions as it just picked one of the two output formats that we were alternating between depending on a kernel config, doing the same for parsing wasn't okay. nr_cpumask_bits can be either nr_cpu_ids or NR_CPUS. We can always use nr_cpu_ids but that is a variable while NR_CPUS is a constant, so it can be more efficient to use NR_CPUS when we can get away with it. Converting the printing functions to nr_cpu_ids makes sense because it affects how the masks get presented to userspace and doesn't break anything; however, using nr_cpu_ids for parsing functions can incorrectly leave the higher bits uninitialized while reading in these masks from userland. As all testing and comparison functions use nr_cpumask_bits which can be larger than nr_cpu_ids, the parsed cpumasks can erroneously yield false negative results. This made the taskstats interface incorrectly return -EINVAL even when the inputs were correct. Fix it by restoring the parse functions to use nr_cpumask_bits instead of nr_cpu_ids.

2017-02-08mm: avoid returning VM_FAULT_RETRY from ->page_mkwrite handlersJan Kara
Some ->page_mkwrite handlers may return VM_FAULT_RETRY as its return code (GFS2 or Lustre can definitely do this). However VM_FAULT_RETRY from ->page_mkwrite is completely unhandled by the mm code and results in locking and writeably mapping the page which definitely is not what the caller wanted. Fix Lustre and block_page_mkwrite_ret() used by other filesystems (notably GFS2) to return VM_FAULT_NOPAGE instead which results in bailing out from the fault code, the CPU then retries the access, and we fault again effectively doing what the handler wanted.

When the first time pynfs runs after rpc/nfsd startup, always get the warning, "Got error: Connection closed" I found the problem is caused by, 1. A new startup of nfsd, rpc.mountd, etc, 2. A rpc request from client (pynfs test, or normal mounting), 3. An ip_map cache is created but invalid, so upcall to rpc.mountd, 4. rpc.mountd process the ip_map upcall, before write the valid data to nfsd, do auth_reload(), and check_useipaddr(), 5. For the first time, old_use_ipaddr = -1, it causes rpc.mountd do write_flush that doing cache_clean, 6. The ip_map cache will be treat as expired and clean, 7. When rpc.mountd write the valid data to nfsd, a new ip_map is created and updated, the cache_check of old ip_map(doing the upcall) will return -ETIMEDOUT. 8. RPC layer return SVC_CLOSE and close the xprt after commit 4d712ef1db05 "svcauth_gss: Close connection when dropping an incoming message" NeilBrown suggest in another email, "If CACHE_VALID is not set, then there is no data in the cache item, so there is nothing to expire.

Devices that offload multipath routes need to be made aware of nexthop status changes. Otherwise, the device will keep forwarding packets to non-functional nexthops.

2017-02-08svcrdma: Clean up RPC-over-RDMA Reply header encoderChuck Lever
Replace C structure-based XDR decoding with pointer arithmetic. Pointer arithmetic is considered more portable, and is used throughout the kernel's existing XDR encoders. The gcc optimizer generates similar assembler code either way. Byte-swapping before a memory store on x86 typically results in an instruction pipeline stall. Avoid byte-swapping when encoding a new header. svcrdma currently doesn't alter a connection's credit grant value after the connection has been accepted, so it is effectively a constant. Cache the byte-swapped value in a separate field. Christoph suggested pulling the header encoding logic into the only function that uses it.

2017-02-08svcrdma: Another sendto chunk list parsing updateChuck Lever
Commit 5fdca6531434 ("svcrdma: Renovate sendto chunk list parsing") missed a spot. svc_rdma_xdr_get_reply_hdr_len() also assumes the Write list has only one Write chunk. There's no harm in making this code more general. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: J. Bruce Fields <bfields@redhat.com>

2017-02-08net: introduce device min_header_lenWillem de Bruijn
The stack must not pass packets to device drivers that are shorter than the minimum link layer header length. Previously, packet sockets would drop packets smaller than or equal to dev->hard_header_len, but this has false positives. Zero length payload is used over Ethernet. Other link layer protocols support variable length headers. Support for validation of these protocols removed the min length check for all protocols. Introduce an explicit dev->min_header_len parameter and drop all packets below this value. Initially, set it to non-zero only for Ethernet and loopback. Other protocols can follow in a patch to net-next.
