Saeed Mahameed says: ==================== mlx5-updates-2019-08-15 This patchset introduces changes in mlx5 devlink health reporters. The highlight of these changes is adding a new reporter: RX reporter mlx5 RX reporter: reports and recovers from timeouts and RX completion error. 1) Perform TX reporter cleanup. In order to maintain the code flow as similar as possible between RX and TX reporters, start the set with cleanup. 2) Prepare for code sharing, generalize and move shared functionality. 3) Refactor and extend TX reporter diagnostics information to align the TX reporter diagnostics output with the RX reporter's diagnostics output. 4) Add helper functions Patch 11: Add RX reporter, initially supports only the diagnostics call back. 5) Change ICOSQ (Internal Operations Send Queue) open/close flow to avoid race between interface down and completion error recovery. 6) Introduce recovery flows for RX ring population timeout on ICOSQ, and for completion errors on ICOSQ and on RQ (Regular receive queues). 7) Include RX reporters in mlx5 documentation. 8) Last two patches of this series, are trivial fixes for previously submitted patches on this release cycle. ==================== Signed-off-by: -

Jeff Kirsher says: ==================== 100GbE Intel Wired LAN Driver Updates 2019-08-20 This series contains updates to ice driver only. Brett fixes the detection of a hung transmit ring by checking the software based tail (next_to_use) to determine if there is pending work. Updates the driver to assume that using more than one receive queue per receive ring container is a rare case, so use unlikely() in the case were we actually need to divide our budget for multiple queues. Fixed an issue where the write back on ITR bit was not being set when interrupts are disabled, which was causing only write backs when polling only when a cache line is filled. Cleans up unnecessary wait times during VF bring up and reset paths. Increased the mailbox size for receive queues that are used to communicate with VFs to accommodate the large number of VFs that the driver can support. Akeem restructures the initialization flows for VFs, including how VFs are configured and resources allocated to improve flows so that when we clean up resources, we do not try to free resources that were never allocated. Organizes code to ensure that VF specific code is located in the SR-IOV specific file. Paul fixes an issue when setting the pause parameter which was incorrectly blocking users from changing receive or transmit pause settings. Ensure register access for MSIX vector index is only done in the PF space and not absolute device space. Usha fixes a potential kernel hang in the DCB rebuild path when in CEE mode, where the ETS recommended DCB configuration is not being set or set correctly. Mitch updates the driver to process all receive descriptors, regardless of the size of the associated data. Tony fixes and issue during the reset/rebuild path of a PF VSI where we were assuming that the PF VSI was always to be enabled, which can attempt to bring up a PF VSI on a downed interface which can lead to various crashes. Pawel fixes up variable definitions to match the type of data being stored. v2: Dropped patch 1 of the series to add ethtool support to query/add channels on a VSI, while we re-qork the functionality to match the ethtool expected behavior to report combined (Tx and Rx) numbers. v3: Updated patch 4 to use kzalloc() and kfree() instead devm_kzalloc() and devm_kfree(). ==================== Signed-off-by:

Currently we use the ICE_MBXQ_LEN for both the Mailbox send and receive queues that are used to communicate with VFs. This is fine for the send queue because the PF driver will lock the queue for every single send, but for the Mailbox receive queue every VF is posting to its Mailbox send queue and the hardware is then handing the message to the PF on its Mailbox receive queue. This becomes a problem with many VFs because it seems to overburden the Mailbox receive queue on the PF. Fix this by increasing the Mailbox receive queue for the PF to 512 entries. The number 512 was determined based on the number of VFs supported by the device. We can have a total of 256 VFs so in the worst case this allows the VFs to put 2 messages in the PFs Mailbox receive queue at the same time. Signed-off-by:

Currently there are a couple places where the VF is waiting too long when checking the status of registers. This is causing the AVF driver to spin for longer than necessary in the __IAVF_STARTUP state. Sometimes it causes the AVF to go into the __IAVF_COMM_FAILED, which may retrigger the __IAVF_STARTUP state. Try to reduce the chance of this happening by removing unnecessary wait times in VF bringup/resets. Signed-off-by:

During rebuild ice_ena_vsi() is called to recover the VSI state. This function assumes the PF VSI is always to be enabled, however, it's possible that during reset/rebuild the interface can be brought down. If this occurs, we can attempt to bring up the PF VSI on a downed interface which can lead to various crashes. If the interface is not running, do not bring up the associated VSI. Signed-off-by:

In some circumstances, the hardware will hand us a receive descriptor which has no data attached, but is otherwise valid. The receive code was improperly ignoring these descriptors, which result in an infinite loop. To fix this, change the receive code to process all descriptors, regardless of the size of the associated data. Add checks to the memory-handling functions to allow for zero size. Signed-off-by:

Currently when busy polling is enabled we aren't setting/enabling WB_ON_ITR in the driver. This doesn't break the driver, but it does cause issues. If we don't enable WB_ON_ITR mode we will still get write-backs from hardware during polling when a cache line has been filled, but if a cache line is not filled we will not get the write-back because WB_ON_ITR is not set. Fix this by enabling WB_ON_ITR in the driver when interrupts are disabled. Signed-off-by:

The first patch is by Geert Uytterhoeven, it removes the unused platform data support from the rcar_can driver. A patch by Nishka Dasgupta marks the structure peak_pciec_i2c_bit_ops in the peak_pci driver as constant. A patch by me removes the custom DMA support from the hi311x driver. The next 4 patches target the tcan4x5x driver and are also by me, they first clean up the driver a bit, and then add missing error handling and fix a bug in the length calculation in the regmap callbacks. The next 2 patches are by me for the m_can_platform driver, they also remove unneeded casts and add missing error handling. The remaining 9 patches all target the mcp251x driver. The first 5 are clean up patches by me, the next relaxes the timing in the mcp251x_hw_reset() function. Alexander Shiyan's patch improves the name which is used while registering the interrupt handler. Phil Elwell's patch improves the mcp251x_open() function to use the DT-supplied interrupt flags instead of hard coding them. The final patch is again by me, it removes the custom DMA support from the hi311x driver. ==================== Signed-off-by:

We have logic to determine the desired promisc mode in _each_ code path. Change things around so that there is a clean split between (a) high-level code that selects the new mode, and (b) implementations of the various mechanisms to program this mode.

When processing the reply for a vnicc cmd, there's no need to remember which specific sub-cmd type we initially sent. The reply itself contains all the needed information. Signed-off-by:
-
Julian Wiedmann authored
Except for card->read_cmd, every cmd we issue now passes through qeth_send_control_data() and allocates a qeth_reply struct. The way we use this struct requires additional refcounting, and pointer tracking. Clean up things by moving most of qeth_reply's content into the main cmd struct. This keeps things in one place, saves us the additional refcounting and simplifies the overall code flow. A nice little benefit is that we can now match incoming replies against the pending requests themselves, without caching the requests' seqnos. The qeth_reply struct stays around for a little bit longer in a shrunk form, to avoid touching every single callback. Signed-off-by:
-
Julian Wiedmann authored
Current code releases the cmd struct after its initial IO has completed. Any reply processing is done independently, using a separate qeth_reply struct. In preparation for merging the cmd and reply structs together, take an additional reference on the cmd object so that it stays around all the way until qeth_send_control_data() returns.

qeth_snmp_command_cb() is the only cmd callback that pulls the reply's data length from a low-level transport header field. This requires additional complexity (ie. reply->offset) to make the header accessible to what is supposed to be a pure IPA cmd callback. Adapter cmds have a length field in their sub-cmd header, get the data length from there instead. Signed-off-by:

Julian Wiedmann authored
When an cmd IO completes in qeth_irq(), calculate how much data was processed by the device and pass this value to the cmd's callback. This allows cmds that retrieve data from the device to check whether sufficient data was received, so we do that in qeth_read_conf_data_cb(). Suggested-by:

Previously, mlx5_cleanup_fc_stats() would cleanup the flow counter pool beofre releasing all the counters to it, which would result in flow counter bulks not getting freed. Resolve this by changing the order in which elements of fc_stats are cleaned up, so that the flow counter pool is cleaned up after all the counters are released. Also move cleanup actions for freeing the bulk query memory and destroying the idr to the end of mlx5_cleanup_fc_stats(). Signed-off-by:

Recent rtnl lock dependency refactoring changed encap entry attach code to insert encap entry to hash table before it was fully initialized in order to allow concurrent tc users to wait on completion for encap entry to finish initialization. That change required all the users of encap entry to obtain reference to it first and for caller that creates encap to put reference to it on error, instead of freeing the entry memory directly. However, releasing reference to such encap entry that wasn't fully initialized causes NULL pointer dereference in mlx5e_rep_encap_entry_detach() which expects e->out_dev to be set and encap to be attached to nhe: [ 1092.454517] BUG: unable to handle page fault for address: 00000000000420e8 [ 1092.454571] #PF: supervisor read access in kernel mode [ 1092.454602] #PF: error_code(0x0000) - not-present page [ 1092.454632] PGD 800000083032c067 P4D 800000083032c067 PUD 84107d067 PMD 0 [ 1092.454673] Oops: 0000 [#1] SMP PTI [ 1092.454697] CPU: 20 PID: 22393 Comm: tc Not tainted 5.3.0-rc3+ #589 [ 1092.454733] Hardware name: Supermicro SYS-2028TP-DECR/X10DRT-P, BIOS 2.0b 03/30/2017 [ 1092.454806] RIP: 0010:mlx5e_rep_encap_entry_detach+0x1c/0x630 [mlx5_core] [ 1092.454845] Code: be f4 ff ff ff e9 11 ff ff ff 0f 1f 40 00 0f 1f 44 00 00 55 48 89 e5 41 57 41 56 41 55 41 54 49 89 fc 53 48 89 f3 48 83 ec 30 <48> 8b 87 28 16 04 00 48 89 f7 48 05 d0 03 00 00 48 89 45 c8 e8 cb [ 1092.454942] RSP: 0018:ffffb6f08421f5a0 EFLAGS: 00010286 [ 1092.454974] RAX: 0000000000000000 RBX: ffff8ab668644e00 RCX: ffffb6f08421f56c [ 1092.455013] RDX: ffff8ab668644e40 RSI: ffff8ab668644e00 RDI: 0000000000000ac0 [ 1092.455053] RBP: ffffb6f08421f5f8 R08: 0000000000000001 R09: 0000000000000000 [ 1092.455092] R10: 0000000000000000 R11: 0000000000000000 R12: 0000000000000ac0 [ 1092.455131] R13: 00000000ffffff9b R14: ffff8ab63f200ac0 R15: ffff8ab668644e40 [ 1092.455171] FS: 00007fa195bdc480(0000) GS:ffff8ab66fa00000(0000) knlGS:0000000000000000 [ 1092.455216] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 1092.455249] CR2: 00000000000420e8 CR3: 0000000867522001 CR4: 00000000001606e0 [ 1092.455288] Call Trace: [ 1092.455315] ? __mutex_unlock_slowpath+0x4d/0x2a0 [ 1092.455365] mlx5e_encap_dealloc.isra.0+0x31/0x60 [mlx5_core] [ 1092.455424] mlx5e_tc_add_fdb_flow+0x596/0x750 [mlx5_core] [ 1092.455484] __mlx5e_add_fdb_flow+0x152/0x210 [mlx5_core] [ 1092.455534] mlx5e_configure_flower+0x4d5/0xe30 [mlx5_core] [ 1092.455574] tc_setup_cb_call+0x67/0xb0 [ 1092.455601] fl_hw_replace_filter+0x142/0x300 [cls_flower] [ 1092.455639] fl_change+0xd24/0x1bdb [cls_flower] [ 1092.455675] tc_new_tfilter+0x3e0/0x970 [ 1092.455709] ? tc_del_tfilter+0x720/0x720 [ 1092.455735] rtnetlink_rcv_msg+0x389/0x4b0 [ 1092.455763] ? netlink_deliver_tap+0x95/0x400 [ 1092.455791] ? rtnl_dellink+0x2d0/0x2d0 [ 1092.455817] netlink_rcv_skb+0x49/0x110 [ 1092.455844] netlink_unicast+0x171/0x200 [ 1092.455872] netlink_sendmsg+0x224/0x3f0 [ 1092.455901] sock_sendmsg+0x5e/0x60 [ 1092.455924] ___sys_sendmsg+0x2ae/0x330 [ 1092.455950] ? task_work_add+0x43/0x50 [ 1092.455976] ? fput_many+0x45/0x80 [ 1092.456004] ? __lock_acquire+0x248/0x18e0 [ 1092.456033] ? find_held_lock+0x2b/0x80 [ 1092.456058] ? task_work_run+0x7b/0xd0 [ 1092.456085] __sys_sendmsg+0x59/0xa0 [ 1092.457013] do_syscall_64+0x5c/0xb0 [ 1092.457924] entry_SYSCALL_64_after_hwframe+0x49/0xbe [ 1092.458842] RIP: 0033:0x7fa195da27b8 [ 1092.459918] Code: 89 02 48 c7 c0 ff ff ff ff eb bb 0f 1f 80 00 00 00 00 f3 0f 1e fa 48 8d 05 65 8f 0c 00 8b 00 85 c0 75 17 b8 2e 00 00 00 0f 05 <48> 3d 00 f0 ff ff 77 58 c3 0f 1f 80 00 00 00 00 48 83 ec 28 89 54 [ 1092.462634] RSP: 002b:00007fff94409298 EFLAGS: 00000246 ORIG_RAX: 000000000000002e [ 1092.464011] RAX: ffffffffffffffda RBX: 000000005d515b0e RCX: 00007fa195da27b8 [ 1092.465391] RDX: 0000000000000000 RSI: 00007fff94409300 RDI: 0000000000000003 [ 1092.466761] RBP: 0000000000000000 R08: 0000000000000001 R09: 0000000000000006 [ 1092.468121] R10: 0000000000404ec2 R11: 0000000000000246 R12: 0000000000000001 [ 1092.469456] R13: 0000000000480640 R14: 0000000000000016 R15: 0000000000000001 [ 1092.470766] Modules linked in: act_mirred act_tunnel_key cls_flower dummy vxlan ip6_udp_tunnel udp_tunnel sch_ingress nfsv3 nfs_acl nfs lockd grace fscache tun bridge stp llc sunrpc rdma_ucm rdma_cm iw_cm ib_cm mlx5_ib ib_uverbs ib_core intel_rapl_msr intel_rapl_common sb_edac x86_pkg_temp_thermal intel_powerclamp coretemp mlx5_core kvm_intel kvm irqbypass crct10dif_pclmul mei_me crc32_pclmul crc32 c_intel igb iTCO_wdt ghash_clmulni_intel ses mlxfw intel_cstate iTCO_vendor_support ptp intel_uncore lpc_ich pps_core mei i2c_i801 joydev intel_rapl_perf ioatdma enclosure ipmi_ssif pcspkr dca wmi ipmi_ si ipmi_devintf ipmi_msghandler acpi_pad acpi_power_meter ast i2c_algo_bit drm_vram_helper ttm drm_kms_helper drm mpt3sas raid_class scsi_transport_sas [ 1092.479618] CR2: 00000000000420e8 [ 1092.481214] ---[ end trace ce2e0f4d9a67f604 ]--- To fix the issue, set e->compl_result to positive value after encap was initialized successfully.
