2022-08-29net: Use u64_stats_fetch_begin_irq() for stats fetch.Sebastian Andrzej Siewior2-4/+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.

2022-07-06net: hinic: avoid kernel hung in hinic_get_stats64()Qiao Ma1-4/+0
When using hinic device as a bond slave device, and reading device stats of master bond device, the kernel may hung. 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.

2022-07-06net: hinic: fix bug that ethtool get wrong statsQiao Ma4-48/+16
Function hinic_get_stats64() will do two operations: 1. reads stats from every hinic_rxq/txq and accumulates them 2. calls hinic_rxq/txq_clean_stats() to clean every rxq/txq's stats For hinic_get_stats64(), it could get right data, because it sums all data to nic_dev->rx_stats/tx_stats. 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.

2022-06-27hinic: Use the bitmap API when applicableChristophe JAILLET1-5/+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.

2022-06-17hinic: Replace memcpy() with direct assignmentKees Cook1-3/+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.

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.

2021-12-10hinic: Use irq_set_affinity_and_hint()Nitesh Narayan Lal1-2/+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.

2021-08-09devlink: Set device as early as possibleLeon Romanovsky4-8/+8
All kernel devlink implementations call to devlink_alloc() during initialization routine for specific device which is used later as a parent device for devlink_register(). Such late device assignment causes to the situation which requires us to call to device_register() before setting other parameters, but that call opens devlink to the world and makes accessible for the netlink users. Any attempt to move devlink_register() to be the last call generates the following error due to access to the devlink->dev pointer. [ 8.758862] devlink_nl_param_fill+0x2e8/0xe50 [ 8.760305] devlink_param_notify+0x6d/0x180 [ 8.760435] __devlink_params_register+0x2f1/0x670 [ 8.760558] devlink_params_register+0x1e/0x20 The simple change of API to set devlink device in the devlink_alloc() instead of devlink_register() fixes all this above and ensures that prior to call to devlink_register() everything already set.

2020-11-19devlink: move request_firmware out of driverJacob Keller1-11/+1
All drivers which implement the devlink flash update support, with the exception of netdevsim, use either request_firmware or request_firmware_direct to locate the firmware file. Rather than having each driver do this separately as part of its .flash_update implementation, perform the request_firmware within net/core/devlink.c Replace the file_name parameter in the struct devlink_flash_update_params with a pointer to the fw object. Use request_firmware rather than request_firmware_direct. Although most Linux distributions today do not have the fallback mechanism implemented, only about half the drivers used the _direct request, as compared to the generic request_firmware. In the event that a distribution does support the fallback mechanism, the devlink flash update ought to be able to use it to provide the firmware contents. For distributions which do not support the fallback userspace mechanism, there should be essentially no difference between request_firmware and request_firmware_direct.

2020-09-25devlink: convert flash_update to use params structureJacob Keller1-3/+2
The devlink core recently gained support for checking whether the driver supports a flash_update parameter, via `supported_flash_update_params`. However, parameters are specified as function arguments. Adding a new parameter still requires modifying the signature of the .flash_update callback in all drivers. Convert the .flash_update function to take a new `struct devlink_flash_update_params` instead. By using this structure, and the `supported_flash_update_params` bit field, a new parameter to flash_update can be added without requiring modification to existing drivers. As before, all parameters except file_name will require driver opt-in. Because file_name is a necessary field to for the flash_update to make sense, no "SUPPORTED" bitflag is provided and it is always considered valid. All future additional parameters will require a new bit in the supported_flash_update_params bitfield.

2020-09-25devlink: check flash_update parameter support in net coreJacob Keller1-3/+0
When implementing .flash_update, drivers which do not support per-component update are manually checking the component parameter to verify that it is NULL. Without this check, the driver might accept an update request with a component specified even though it will not honor such a request. Instead of having each driver check this, move the logic into net/core/devlink.c, and use a new `supported_flash_update_params` field in the devlink_ops. Drivers which will support per-component update must now specify this by setting DEVLINK_SUPPORT_FLASH_UPDATE_COMPONENT in the supported_flash_update_params in their devlink_ops. This helps ensure that drivers do not forget to check for a NULL component if they do not support per-component update. This also enables a slightly better error message by enabling the core stack to set the netlink bad attribute message to indicate precisely the unsupported attribute in the message. Going forward, any new additional parameter to flash update will require a bit in the supported_flash_update_params bitfield.
