2017-05-01iov_iter: don't revert iov buffer if csum errorDing Tianhong1-6/+7
The patch 327868212381 (make skb_copy_datagram_msg() et.al. preserve ->msg_iter on error) will revert the iov buffer if copy to iter failed, but it didn't copy any datagram if the skb_checksum_complete error, so no need to revert any data at this place. v2: Sabrina notice that return -EFAULT when checksum error is not correct here, it would confuse the caller about the return value, so fix it.

2017-05-01IB/rxe: Don't clamp residual length to mtuJohannes Thumshirn1-2/+0
When reading a RDMA WRITE FIRST packet we copy the DMA length from the RDMA header into the qp->resp.resid variable for later use. Later in check_rkey() we clamp it to the MTU if the packet is an RDMA WRITE packet and has a residual length bigger than the MTU. Later in write_data_in() we subtract the payload of the packet from the residual length. If the packet happens to have a payload of exactly the MTU size we end up with a residual length of 0 despite the packet not being the last in the conversation. When the next packet in the conversation arrives, we don't have any residual length left and thus set the QP into an error state. This broke NVMe over Fabrics functionality over rdma_rxe.ko The patch was verified using the following test. # echo eth0 > /sys/module/rdma_rxe/parameters/add # nvme connect -t rdma -a 192.168.155.101 -s 1023 -n nvmf-test # mkfs.xfs -fK /dev/nvme0n1 meta-data=/dev/nvme0n1 isize=256 agcount=4, agsize=65536 blks = sectsz=4096 attr=2, projid32bit=1 = crc=0 finobt=0, sparse=0 data = bsize=4096 blocks=262144, imaxpct=25 = sunit=0 swidth=0 blks naming =version 2 bsize=4096 ascii-ci=0 ftype=1 log =internal log bsize=4096 blocks=2560, version=2 = sectsz=4096 sunit=1 blks, lazy-count=1 realtime =none extsz=4096 blocks=0, rtextents=0 # mount /dev/nvme0n1 /tmp/ [ 148.923263] XFS (nvme0n1): Mounting V4 Filesystem [ 148.961196] XFS (nvme0n1): Ending clean mount # dd if=/dev/urandom of=test.bin bs=1M count=128 128+0 records in 128+0 records out 134217728 bytes (134 MB, 128 MiB) copied, 0.437991 s, 306 MB/s # sha256sum test.bin cde42941f045efa8c4f0f157ab6f29741753cdd8d1cff93a6b03649d83c4129a test.bin # cp test.bin /tmp/ sha256sum /tmp/test.bin cde42941f045efa8c4f0f157ab6f29741753cdd8d1cff93a6b03649d83c4129a /tmp/test.bin Signed-off-by: Johannes Thumshirn <[email protected]> Cc: Hannes Reinecke <[email protected]> Cc: Sagi Grimberg <[email protected]> Cc: Max Gurtovoy <[email protected]> Acked-by: Moni Shoua <[email protected]> Signed-off-by: Doug Ledford <[email protected]>

BFQ is meant to be used on desktop type single drives, providing good fairness. From Paolo. - Add Kyber IO scheduler. This is a full multiqueue aware scheduler, using a scalable token based algorithm that throttles IO based on live completion IO stats, similary to blk-wbt.

This continues the work of separating backing device life times, solving various problems with hot removal. - A series of updates for lightnvm, mostly from Javier. Includes a 'pblk' target that exposes an open channel SSD as a physical block device. - A series of fixes and improvements for nbd from Josef. - A series from Omar, removing queue sharing between devices on mostly legacy drivers. This helps us clean up other bits, if we know that a queue only has a single device backing. This has been overdue for more than a decade. - Fixes for the blk-stats, and improvements to unify the stats and user windows. This both improves blk-wbt, and enables other users to register a need to receive IO stats for a device. From Omar. - blk-throttle improvements from Shaohua. This provides a scalable framework for implementing scalable priotization - particularly for blk-mq, but applicable to any type of block device. The interface is marked experimental for now. - Bucketized IO stats for IO polling from Stephen Bates.

2017-05-01mlxsw: spectrum_router: Simplify VRF enslavementIdo Schimmel3-131/+63
When a netdev is enslaved to a VRF master, its router interface (RIF) needs to be destroyed (if exists) and a new one created using the corresponding virtual router (VR). >From the driver's perspective, the above is equivalent to an inetaddr event sent for this netdev. Therefore, when a port netdev (or its uppers) are enslaved to a VRF master, call the same function that would've been called had a NETDEV_UP was sent for this netdev in the inetaddr notification chain. This patch also fixes a bug when a LAG netdev with an existing RIF is enslaved to a VRF. Before this patch, each LAG port would drop the reference on the RIF, but would re-join the same one (in the wrong VR) soon after. With this patch, the corresponding RIF is first destroyed and a new one is created using the correct VR.

git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux mlx5-updates-2017-04-30 Or says: ================ mlx5 neigh update This series (whose code name is 'neigh update') from Hadar, enhances the mlx5 TC IP tunnel offloads to deal with changes to tunnel destination neighbours used in offloaded flows which involved encapsulation. In order to keep track on the validity state of such neighbours, we register a netevent notifier callback and act on NEIGH_UPDATE events: if a neighbour becomes valid, offload the related flows to HW (the other way around when neigh becomes invalid) and similarly when a neigh mac addresses changes. Since this traffic is offloaded from the host OS, the neighbour for the IP tunnel destination can mistakenly become STALE and deleted by the kernel since its 'used' value wasn't changed. To address that, we proactively update the neighbour 'used' value every DELAY_PROBE_TIME seconds, using time stamps generated by the existing driver code for HW flow counters. We use the DELAY_PROBE_TIME_UPDATE event to adjust the frequency of the updates. Prior to the core of the series, there's a patch from Saeed that introduces an extendable vport representor implementation scheme. It provides a separation between the eswitch to the netdev related aspects of the representors. We would like to thank Ido Schimmel and Ilya Lesokhin for their coaching && advice through the long design and review cycles while we struggled to understand and (hopefully correctly) implement the locking around the different driver flows(..) . - Or. ================= Misc Updates: From Tariq: Some small performance and trivial code optimization for mlx5 netdev driver - Optimize poll ICOSQ completion queue - Use prefetchw when a write is to follow - Use u8 as ownership type in mlx5e_get_cqe() From Eran: - Disable LRO by default on specific setups From Eli: - Small cleanup for E-Switch to avoid redundant allocation Signed-off-by: David S.

2017-05-01bpf: enhance verifier to understand stack pointer arithmeticYonghong Song2-6/+23
llvm 4.0 and above generates the code like below: .... 440: (b7) r1 = 15 441: (05) goto pc+73 515: (79) r6 = *(u64 *)(r10 -152) 516: (bf) r7 = r10 517: (07) r7 += -112 518: (bf) r2 = r7 519: (0f) r2 += r1 520: (71) r1 = *(u8 *)(r8 +0) 521: (73) *(u8 *)(r2 +45) = r1 .... and the verifier complains "R2 invalid mem access 'inv'" for insn #521. This is because verifier marks register r2 as unknown value after #519 where r2 is a stack pointer and r1 holds a constant value. Teach verifier to recognize "stack_ptr + imm" and "stack_ptr + reg with const val" as valid stack_ptr with new offset.

Pablo Neira Ayuso says: ==================== Netfilter/IPVS updates for net-next The following patchset contains Netfilter updates for your net-next tree. A large bunch of code cleanups, simplify the conntrack extension codebase, get rid of the fake conntrack object, speed up netns by selective synchronize_net() calls. More specifically, they are: 1) Check for ct->status bit instead of using nfct_nat() from IPVS and Netfilter codebase, patch from Florian Westphal. 2) Use kcalloc() wherever possible in the IPVS code, from Varsha Rao. 3) Simplify FTP IPVS helper module registration path, from Arushi Singhal. 4) Introduce nft_is_base_chain() helper function. 5) Enforce expectation limit from userspace conntrack helper, from Gao Feng. 6) Add nf_ct_remove_expect() helper function, from Gao Feng. 7) NAT mangle helper function return boolean, from Gao Feng. 8) ctnetlink_alloc_expect() should only work for conntrack with helpers, from Gao Feng. 9) Add nfnl_msg_type() helper function to nfnetlink to build the netlink message type. 10) Get rid of unnecessary cast on void, from simran singhal. 11) Use seq_puts()/seq_putc() instead of seq_printf() where possible, also from simran singhal. 12) Use list_prev_entry() from nf_tables, from simran signhal. 13) Remove unnecessary & on pointer function in the Netfilter and IPVS code. 14) Remove obsolete comment on set of rules per CPU in ip6_tables, no longer true. From Arushi Singhal. 15) Remove duplicated nf_conntrack_l4proto_udplite4, from Gao Feng. 16) Remove unnecessary nested rcu_read_lock() in __nf_nat_decode_session(). Code running from hooks are already guaranteed to run under RCU read side. 17) Remove deadcode in nf_tables_getobj(), from Aaron Conole. 18) Remove double assignment in nf_ct_l4proto_pernet_unregister_one(), also from Aaron. 19) Get rid of unsed __ip_set_get_netlink(), from Aaron Conole. 20) Don't propagate NF_DROP error to userspace via ctnetlink in __nf_nat_alloc_null_binding() function, from Gao Feng. 21) Revisit nf_ct_deliver_cached_events() to remove unnecessary checks, from Gao Feng. 22) Kill the fake untracked conntrack objects, use ctinfo instead to annotate a conntrack object is untracked, from Florian Westphal. 23) Remove nf_ct_is_untracked(), now obsolete since we have no conntrack template anymore, from Florian. 24) Add event mask support to nft_ct, also from Florian. 25) Move nf_conn_help structure to include/net/netfilter/nf_conntrack_helper.h. 26) Add a fixed 32 bytes scratchpad area for conntrack helpers. Thus, we don't deal with variable conntrack extensions anymore. Make sure userspace conntrack helper doesn't go over that size. Remove variable size ct extension infrastructure now this code got no more clients. From Florian Westphal. 27) Restore offset and length of nf_ct_ext structure to 8 bytes now that wraparound is not possible any longer, also from Florian. 28) Allow to get rid of unassured flows under stress in conntrack, this applies to DCCP, SCTP and TCP protocols, from Florian. 29) Shrink size of nf_conntrack_ecache structure, from Florian. 30) Use TCP_MAX_WSCALE instead of hardcoded 14 in TCP tracker, from Gao Feng. 31) Register SYNPROXY hooks on demand, from Florian Westphal. 32) Use pernet hook whenever possible, instead of global hook registration, from Florian Westphal. 33) Pass hook structure to ebt_register_table() to consolidate some infrastructure code, from Florian Westphal. 34) Use consume_skb() and return NF_STOLEN, instead of NF_DROP in the SYNPROXY code, to make sure device stats are not fooled, patch from Gao Feng. 35) Remove NF_CT_EXT_F_PREALLOC this kills quite some code that we don't need anymore if we just select a fixed size instead of expensive runtime time calculation of this. From Florian. 36) Constify nf_ct_extend_register() and nf_ct_extend_unregister(), from Florian. 37) Simplify nf_ct_ext_add(), this kills nf_ct_ext_create(), from Florian. 38) Attach NAT extension on-demand from masquerade and pptp helper path, from Florian. 39) Get rid of useless ip_vs_set_state_timeout(), from Aaron Conole. 40) Speed up netns by selective calls of synchronize_net(), from Florian Westphal. 41) Silence stack size warning gcc in 32-bit arch in snmp helper, from Florian. 42) Inconditionally call nf_ct_ext_destroy(), even if we have no extensions, to deal with the NF_NAT_MANIP_SRC case.
