These are the use-cases where the pkey needs to be tested to see if a packet needs to be dropped. a) Check if pkey is not FULL_MGMT_P_KEY or LIM_MGMT_P_KEY, drop the packet as it's not part of the management partition. Self-originated packets are an exception. b) If pkey index points to FULL_MGMT_P_KEY and LIM_MGMT_P_KEY is in the table, the packet is coming from a management node, and the receiving node is also a management node, so it is safe for the packet to go through. c) If pkey index points to FULL_MGMT_P_KEY and LIM_MGMT_P_KEY is NOT in the table, drop the packet as LIM_MGMT_P_KEY should always be in the pkey table. It could be a misconfiguration. d) If pkey index points to LIM_MGMT_P_KEY and FULL_MGMT_P_KEY is NOT in the table, it is safe for the packet to go through since a non-management node is talking to another non-managment node. e) If pkey index points to LIM_MGMT_P_KEY and FULL_MGMT_P_KEY is in the table, drop the packet because a non-management node is talking to a management node, and it could be an attack. For the implementation, these rules can be simplied to only checking for (a) and (e). There's no need to check for rule (b) as the packet doesn't need to be dropped. Rule (c) is not possible in the driver as LIM_MGMT_P_KEY is always in the pkey table. Reviewed-by: NMichael J.

__subn_get_opa_portinfo stores value returned by hfi1_get_ib_cfg() as operational vls. hfi1_get_ib_cfg() returns vls_operational field in hfi1_pportdata. The problem with this is that the value is always equal to vls_supported field in hfi1_pportdata. The logic to calculate operational_vls is to set value passed by FM (in __subn_set_opa_portinfo routine). If no value is passed then default value is stored in operational_vls. Field actual_vls_operational is calculated on the basis of buffer control table. Hence, modifying hfi1_get_ib_cfg() to return actual_operational_vls when used with HFI1_IB_CFG_OP_VLS parameter Reviewed-by: NMike Marciniszyn <mike.marciniszyn@intel.com> Reviewed-by: NDennis Dalessandro <dennis.dalessandro@intel.com> Signed-off-by: NPatel Jay P <jay.p.patel@intel.com> Signed-off-by: NDennis Dalessandro <dennis.dalessandro@intel.com> Signed-off-by: NDoug Ledford <dledford@redhat.com>

The handler for link init state (HLS_UP_INIT) notifies userspace (update_statusp()) before enabling the device (RCV_CTRL_RCV_PORT_ENABLE_SMASK) or setting the device state (ppd->host_link_state). This causes a race condition where the userspace thinks the interface is in the INIT state before the driver has set that state. Rework the code path to eliminate the race.

rdma_nl_rcv_msg() checks to see if it should use the .dump() callback or the .doit() callback. The check is done with this check: if (flags & NLM_F_DUMP) ... The NLM_F_DUMP flag is two bits (NLM_F_ROOT | NLM_F_MATCH). When an RDMA_NL_LS message (response) is received, the bit used for indicating an error is the same bit as NLM_F_ROOT. NLM_F_ROOT == (0x100) == RDMA_NL_LS_F_ERR. ibacm sends a response with the RDMA_NL_LS_F_ERR bit set if an error occurs in the service. The current code then misinterprets the NLM_F_DUMP bit and trys to call the .dump() callback. If the .dump() callback for the specified request is not available (which is true for the RDMA_NL_LS messages) the following Oops occurs: [ 4555.960256] BUG: unable to handle kernel NULL pointer dereference at (null) [ 4555.969046] IP: (null) [ 4555.972664] PGD 10543f1067 P4D 10543f1067 PUD 1033f93067 PMD 0 [ 4555.979287] Oops: 0010 [#1] SMP [ 4555.982809] Modules linked in: rpcrdma ib_isert iscsi_target_mod target_core_mod ib_iser libiscsi scsi_transport_iscsi ib_ipoib rdma_ucm ib_ucm ib_uverbs ib_umad rdma_cm ib_cm iw_cm dm_mirror dm_region_hash dm_log dm_mod dax sb_edac x86_pkg_temp_thermal intel_powerclamp coretemp kvm irqbypass crct10dif_pclmul crc32_pclmul ghash_clmulni_intel pcbc aesni_intel crypto_simd glue_helper cryptd hfi1 rdmavt iTCO_wdt iTCO_vendor_support ib_core mei_me lpc_ich pcspkr mei ioatdma sg shpchp i2c_i801 mfd_core wmi ipmi_si ipmi_devintf ipmi_msghandler acpi_power_meter acpi_pad nfsd auth_rpcgss nfs_acl lockd grace sunrpc ip_tables ext4 mbcache jbd2 sd_mod mgag200 drm_kms_helper syscopyarea sysfillrect sysimgblt fb_sys_fops ttm igb ahci crc32c_intel ptp libahci pps_core drm dca libata i2c_algo_bit i2c_core [ 4556.061190] CPU: 54 PID: 9841 Comm: ibacm Tainted: G I 4.14.0-rc2+ #6 [ 4556.069667] Hardware name: Intel Corporation S2600WT2/S2600WT2, BIOS SE5C610.86B.01.01.0008.021120151325 02/11/2015 [ 4556.081339] task: ffff880855f42d00 task.stack: ffffc900246b4000 [ 4556.087967] RIP: 0010: (null) [ 4556.092166] RSP: 0018:ffffc900246b7bc8 EFLAGS: 00010246 [ 4556.098018] RAX: ffffffff81dbe9e0 RBX: ffff881058bb1000 RCX: 0000000000000000 [ 4556.105997] RDX: 0000000000001100 RSI: ffff881058bb1320 RDI: ffff881056362000 [ 4556.113984] RBP: ffffc900246b7bf8 R08: 0000000000000ec0 R09: 0000000000001100 [ 4556.121971] R10: ffff8810573a5000 R11: 0000000000000000 R12: ffff881056362000 [ 4556.129957] R13: 0000000000000ec0 R14: ffff881058bb1320 R15: 0000000000000ec0 [ 4556.137945] FS: 00007fe0ba5a38c0(0000) GS:ffff88105f080000(0000) knlGS:0000000000000000 [ 4556.147000] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 4556.153433] CR2: 0000000000000000 CR3: 0000001056f5d003 CR4: 00000000001606e0 [ 4556.161419] Call Trace: [ 4556.164167] ? netlink_dump+0x12c/0x290 [ 4556.168468] __netlink_dump_start+0x186/0x1f0 [ 4556.173357] rdma_nl_rcv_msg+0x193/0x1b0 [ib_core] [ 4556.178724] rdma_nl_rcv+0xdc/0x130 [ib_core] [ 4556.183604] netlink_unicast+0x181/0x240 [ 4556.187998] netlink_sendmsg+0x2c2/0x3b0 [ 4556.192392] sock_sendmsg+0x38/0x50 [ 4556.196299] SYSC_sendto+0x102/0x190 [ 4556.200308] ? __audit_syscall_entry+0xaf/0x100 [ 4556.205387] ? syscall_trace_enter+0x1d0/0x2b0 [ 4556.210366] ? __audit_syscall_exit+0x209/0x290 [ 4556.215442] SyS_sendto+0xe/0x10 [ 4556.219060] do_syscall_64+0x67/0x1b0 [ 4556.223165] entry_SYSCALL64_slow_path+0x25/0x25 [ 4556.228328] RIP: 0033:0x7fe0b9db2a63 [ 4556.232333] RSP: 002b:00007ffc55edc260 EFLAGS: 00000293 ORIG_RAX: 000000000000002c [ 4556.240808] RAX: ffffffffffffffda RBX: 0000000000000010 RCX: 00007fe0b9db2a63 [ 4556.248796] RDX: 0000000000000010 RSI: 00007ffc55edc280 RDI: 000000000000000d [ 4556.256782] RBP: 00007ffc55edc670 R08: 00007ffc55edc270 R09: 000000000000000c [ 4556.265321] R10: 0000000000000000 R11: 0000000000000293 R12: 00007ffc55edc280 [ 4556.273846] R13: 000000000260b400 R14: 000000000000000d R15: 0000000000000001 [ 4556.282368] Code: Bad RIP value.

In recent code, two path record entries are alwasy cleared while allocated could be either one or two path record entries. This leads to zero out of unallocated memory. This fix initializes alternative path record only when alternative path is set. While we are at it, path record allocation doesn't check for OPA alternative path, but rest of the code checks for OPA alternative path. Path record allocation code doesn't check for OPA alternative LID. This can further lead to memory corruption when only one path record is allocated, but there is actually alternative OPA path record present in CM request.

The device can support receive Stateless Offloads for the inner packet's fields only when the packet is processed by TIR which is enabled to support tunneling. Otherwise, the device treats the packet as an ordinary non-tunneling packet and receive offloads can be done only for the outer packet's field. In order to enable receive Stateless Offloading support for incoming tunneling traffic the TIR should be created with tunneled_offload_en. Tunneling offloads is supported only be raw ethernet QP.

Allow creation of a multi-packet receive queue. In order to create a multi-packet RQ, the following fields in the mlx5_ib_rwq should be set: - log_num_strides: Log of number of strides per WQE - single_stride_log_num_of_bytes: Log of a single stride size - two_byte_shift_en: When enabled, hardware pads 2 bytes of zeros before writing the message to memory (e.g. for the IP alignment).

This patch reports the device's striding RQ capabilities to the user-space: - min/max_single_stride_log_num_of_bytes: Log of min/max number of bytes in a single stride. - min/max_single_wqe_log_num_of_strides: Log of min/max number of strides in a single WQE. - supported_qpts: A bit mask to know which QP types support multi- packet RQ, for now only Raw Packet QPs.

This patch updates the PD specification to 16M for hip08. And it updates the numbers of mtt and cqe segments for the buddy. As the CQE supports hop num 1 addressing, the CQE specification is 64k. This patch updates to set the CQE specification to 64k.

NAPI budget is 64 packets, while maximum polling size for the send CQ is 16. Let's bring them in sync, so the NAPI budget will be reused completely.
