| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A problem about hinic create debugfs failed is triggered with the following log given: [ 931.419023] debugfs: Directory 'hinic' with parent '/' already present! The reason is that hinic_module_init() returns pci_register_driver() directly without checking its return value, if pci_register_driver() failed, it returns without destroy the newly created debugfs, resulting the debugfs of hinic can never be created later. hinic_module_init() hinic_dbg_register_debugfs() # create debugfs directory pci_register_driver() driver_register() bus_add_driver() priv = kzalloc(...) # OOM happened # return without destroy debugfs directory Fix by removing debugfs when pci_register_driver() returns error.

* | net: hinic: Add control command support for VF PMD driver in DPDKCai Huoqing2022-11-072-0/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | HINIC has a mailbox for PF-VF communication and the VF driver could send port control command to PF driver via mailbox. The control command only can be set to register in PF, so add support in PF driver for VF PMD driver control command when VF PMD driver work with linux PF driver. Then, no need to add handlers to nic_vf_cmd_msg_handler[], because the host driver just forwards it to the firmware. Actually the firmware works on a coprocessor MGMT_CPU(inside the NIC) which will recv and deal with these commands. Signed-off-by: Cai Huoqing <cai.huoqing@linux.dev> Signed-off-by: David S.

* net: Use u64_stats_fetch_begin_irq() for stats fetch.Sebastian Andrzej Siewior2022-08-292-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On 32bit-UP u64_stats_fetch_begin() disables only preemption. If the reader is in preemptible context and the writer side (u64_stats_update_begin*()) runs in an interrupt context (IRQ or softirq) then the writer can update the stats during the read operation. This update remains undetected. Use u64_stats_fetch_begin_irq() to ensure the stats fetch on 32bit-UP are not interrupted by a writer. 32bit-SMP remains unaffected by this change. Cc: "David S.

The kernel panic calltrace as follows: Kernel panic - not syncing: softlockup: hung tasks Call trace: native_queued_spin_lock_slowpath+0x1ec/0x31c dev_get_stats+0x60/0xcc dev_seq_printf_stats+0x40/0x120 dev_seq_show+0x1c/0x40 seq_read_iter+0x3c8/0x4dc seq_read+0xe0/0x130 proc_reg_read+0xa8/0xe0 vfs_read+0xb0/0x1d4 ksys_read+0x70/0xfc __arm64_sys_read+0x20/0x30 el0_svc_common+0x88/0x234 do_el0_svc+0x2c/0x90 el0_svc+0x1c/0x30 el0_sync_handler+0xa8/0xb0 el0_sync+0x148/0x180 And the calltrace of task that actually caused kernel hungs as follows: __switch_to+124 __schedule+548 schedule+72 schedule_timeout+348 __down_common+188 __down+24 down+104 hinic_get_stats64+44 [hinic] dev_get_stats+92 bond_get_stats+172 [bonding] dev_get_stats+92 dev_seq_printf_stats+60 dev_seq_show+24 seq_read_iter+964 seq_read+220 proc_reg_read+164 vfs_read+172 ksys_read+108 __arm64_sys_read+28 el0_svc_common+132 do_el0_svc+40 el0_svc+24 el0_sync_handler+164 el0_sync+324 When getting device stats from bond, kernel will call bond_get_stats(). It first holds the spinlock bond->stats_lock, and then call hinic_get_stats64() to collect hinic device's stats. However, hinic_get_stats64() calls `down(&nic_dev->mgmt_lock)` to protect its critical section, which may schedule current task out. And if system is under high pressure, the task cannot be woken up immediately, which eventually triggers kernel hung panic. Since previous patch has replaced hinic_dev.tx_stats/rx_stats with local variable in hinic_get_stats64(), there is nothing need to be protected by lock, so just removing down()/up() is ok.

But it is wrong for get_drv_queue_stats(), this function will read hinic_rxq's stats, which have been cleared to zero by hinic_get_stats64(). I have observed hinic's cleanup operation by using such command: > watch -n 1 "cat ethtool -S eth4 | tail -40" Result before: ... rxq7_pkts: 1 rxq7_bytes: 90 rxq7_errors: 0 rxq7_csum_errors: 0 rxq7_other_errors: 0 ... rxq9_pkts: 11 rxq9_bytes: 726 rxq9_errors: 0 rxq9_csum_errors: 0 rxq9_other_errors: 0 ... rxq11_pkts: 0 rxq11_bytes: 0 rxq11_errors: 0 rxq11_csum_errors: 0 rxq11_other_errors: 0 Result after a few seconds: ... rxq7_pkts: 0 rxq7_bytes: 0 rxq7_errors: 0 rxq7_csum_errors: 0 rxq7_other_errors: 0 ... rxq9_pkts: 2 rxq9_bytes: 132 rxq9_errors: 0 rxq9_csum_errors: 0 rxq9_other_errors: 0 ... rxq11_pkts: 1 rxq11_bytes: 170 rxq11_errors: 0 rxq11_csum_errors: 0 rxq11_other_errors: 0 To solve this problem, we just keep every queue's total stats in their own queue (aka hinic_{rxq|txq}), and simply sum all per-queue stats every time calling hinic_get_stats64(). With that solution, there is no need to clean per-queue stats now, and there is no need to maintain global hinic_dev.{tx|rx}_stats, too.

* hinic: Use the bitmap API when applicableChristophe JAILLET2022-06-271-5/+2
| | | | | | | | | | | | | | | | | 'vlan_bitmap' is a bitmap and is used as such. So allocate it with devm_bitmap_zalloc() and its explicit bit size (i.e. VLAN_N_VID). This avoids the need of the VLAN_BITMAP_SIZE macro which: - needlessly has a 'nic_dev' parameter - should be "long" (and not byte) aligned, so that the bitmap semantic is respected This is in fact not an issue because VLAN_N_VID is 4096 at the time being, but devm_bitmap_zalloc() is less verbose and easier to understand.

* hinic: Replace memcpy() with direct assignmentKees Cook2022-06-171-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Under CONFIG_FORTIFY_SOURCE=y and CONFIG_UBSAN_BOUNDS=y, Clang is bugged here for calculating the size of the destination buffer (0x10 instead of 0x14). This copy is a fixed size (sizeof(struct fw_section_info_st)), with the source and dest being struct fw_section_info_st, so the memcpy should be safe, assuming the index is within bounds, which is UBSAN_BOUNDS's responsibility to figure out. Avoid the whole thing and just do a direct assignment. This results in no change to the executable code. Cc: "David S.

| * | hinic: Use irq_set_affinity_and_hint()Nitesh Narayan Lal2021-12-101-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver uses irq_set_affinity_hint() to: - Set the affinity_hint which is consumed by the userspace for distributing the interrupts - Enforce affinity As per commit 352f58b0d9f2 ("net-next/hinic: Set Rxq irq to specific cpu for NUMA"), the hinic driver enforces its own affinity to bind IRQs to the local NUMA node. However, irq_set_affinity_hint() applying the provided cpumask as an affinity for the interrupt is an undocumented side effect. To remove this side effect irq_set_affinity_hint() has been marked as deprecated and new interfaces have been introduced. Hence, replace the irq_set_affinity_hint() with the new interface irq_set_affinity_and_hint() where the provided mask needs to be applied as the affinity and affinity_hint pointer needs to be set and replace with irq_update_affinity_hint() where only affinity_hint needs to be updated.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As stated in [1], dma_set_mask() with a 64-bit mask never fails if dev->dma_mask is non-NULL. So, if it fails, the 32 bits case will also fail for the same reason. Simplify code and remove some dead code accordingly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sock.h is pretty heavily used (5k objects rebuilt on x86 after it's touched). We can drop the include of filter.h from it and add a forward declaration of struct sk_filter instead. This decreases the number of rebuilt objects when bpf.h is touched from ~5k to ~1k. There's a lot of missing includes this was masking. Primarily in networking tho, this time.
