2024-03-29net: intel: implement modern PM ops declarationsJesse Brandeburg1-3/+3
Switch the Intel networking drivers to use the new power management ops declaration formats and macros, which allows us to drop __maybe_unused, as well as a bunch of ifdef checking CONFIG_PM. This is safe to do because the compiler drops the unused functions, verified by checking for any of the power management function symbols being present in System.map for a build without CONFIG_PM. If a driver has runtime PM, define the ops with pm_ptr(), and if the driver has Simple PM, use pm_sleep_ptr(), as well as the new versions of the macros for declaring the members of the pm_ops structs.

2023-10-18igbvf: replace deprecated strncpy with strscpyJustin Stitt1-1/+1
`strncpy` is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. We expect netdev->name to be NUL-terminated based on its usage with `strlen` and format strings: | if (strlen(netdev->name) < (IFNAMSIZ - 5)) { | sprintf(adapter->tx_ring->name, "%s-tx-0", netdev->name); Moreover, we do not need NUL-padding as netdev is already zero-allocated: | netdev = alloc_etherdev(sizeof(struct igbvf_adapter)); ... alloc_etherdev() -> alloc_etherdev_mq() -> alloc_etherdev_mqs() -> alloc_netdev_mqs() ... | p = kvzalloc(alloc_size, GFP_KERNEL_ACCOUNT | __GFP_RETRY_MAYFAIL); Considering the above, a suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on the destination buffer without unnecessarily NUL-padding.

2023-03-21igbvf: add PCI reset handler functionsDawid Wesierski1-0/+29
There was a problem with resuming ping after conducting a PCI reset. This commit adds two functions, igbvf_io_prepare and igbvf_io_done, which, after being added to the pci_error_handlers struct, will prepare the drivers for a PCI reset and then bring the interface up and reset it after. This will prevent the driver from ending up in incorrect state. Test_and_set_bit is highly reliable in this context, so we are not including a timeout in this commit This introduces 900ms - 1100ms of overhead to this operation but it's in non-time-critical flow. And also allows the driver to continue functioning after the reset.

2021-12-15igbvf: fix double free in `igbvf_probe`Letu Ren1-0/+1
In `igbvf_probe`, if register_netdev() fails, the program will go to label err_hw_init, and then to label err_ioremap. In free_netdev() which is just below label err_ioremap, there is `list_for_each_entry_safe` and `netif_napi_del` which aims to delete all entries in `dev->napi_list`. The program has added an entry `adapter->rx_ring->napi` which is added by `netif_napi_add` in igbvf_alloc_queues(). However, adapter->rx_ring has been freed below label err_hw_init. So this a UAF. In terms of how to patch the problem, we can refer to igbvf_remove() and delete the entry before `adapter->rx_ring`.

2020-06-25net/intel: remove driver versions from Intel driversJeff Kirsher3-7/+1
As with other networking drivers, remove the unnecessary driver version from the Intel drivers. The ethtool driver information and module version will then report the kernel version instead. For ixgbe, i40e and ice drivers, the driver passes the driver version to the firmware to confirm that we are up and running. So we now pass the value of UTS_RELEASE to the firmware. This adminq call is required per the HAS document. The Device then sends an indication to the BMC that the PF driver is present. This is done using Host NC Driver Status Indication in NC-SI Get Link command or via the Host Network Controller Driver Status Change AEN. What the BMC may do with this information is implementation-dependent, but this is a standard NC-SI 1.1 command we honor per the HAS.

2019-11-07net: ethernet: intel: Demote MTU change prints to debugFlorian Fainelli1-2/+2
Changing a network device MTU can be a fairly frequent operation, and failure to change the MTU is reflected to user-space properly, both by an appropriate message as well as by looking at whether the device's MTU matches the configuration. Demote the prints to debug prints by using netdev_dbg(), making all Intel wired LAN drivers consistent, since they used a mixture of PCI device and network device prints before.

2019-04-08drivers: Remove explicit invocations of mmiowb()Will Deacon1-4/+0
mmiowb() is now implied by spin_unlock() on architectures that require it, so there is no reason to call it from driver code. This patch was generated using coccinelle: @mmiowb@ @@ - mmiowb(); and invoked as: $ for d in drivers include/linux/qed sound; do \ spatch --include-headers --sp-file mmiowb.cocci --dir $d --in-place; done NOTE: mmiowb() has only ever guaranteed ordering in conjunction with spin_unlock(). However, pairing each mmiowb() removal in this patch with the corresponding call to spin_unlock() is not at all trivial, so there is a small chance that this change may regress any drivers incorrectly relying on mmiowb() to order MMIO writes between CPUs using lock-free synchronisation. If you've ended up bisecting to this commit, you can reintroduce the mmiowb() calls using wmb() instead, which should restore the old behaviour on all architectures other than some esoteric ia64 systems.

2018-11-21ethernet/intel: consolidate NAPI and NAPI exitJesse Brandeburg1-3/+6
While reviewing code, I noticed that Eric Dumazet recommends that drivers check the return code of napi_complete_done, and use that to decide to enable interrupts or not when exiting poll. One of the Intel drivers was already fixed (ixgbe). Upon looking at the Intel drivers as a whole, we are handling our polling and NAPI exit in a few different ways based on whether we have multiqueue and whether we have Tx cleanup included. Several drivers had the bug of exiting NAPI with return 0, which appears to mess up the accounting in the stack. Consolidate all the NAPI routines to do best known way of exiting and to just mostly look like each other. 1) check return code of napi_complete_done to control interrupt enable 2) return the actual amount of work done. 3) return budget immediately if need NAPI poll again Tested the changes on e1000e with a high interrupt rate set, and it shows about an 8% reduction in the CPU utilization when busy polling because we aren't re-enabling interrupts when we're about to be polled.

The original issue being fixed in this patch was seen with the ixgbe driver, but the same issue exists with igbvf as well, as the code is very similar. read_barrier_depends is not sufficient to ensure loads following it are not speculatively loaded out of order by the CPU, which can result in stale data being loaded, causing potential system crashes.

2017-08-08igbvf: add lock around mailbox opsGreg Edwards4-0/+56
The PF driver assumes the VF will not send another mailbox message until the PF has written its reply to the previous message. If the VF does, that message will be silently dropped by the PF before it writes its reply to the mailbox. This results in a VF mailbox timeout for posted messages waiting for an ACK, and the VF is reset by the igbvf_watchdog_task in the VM. Add a lock around the VF mailbox ops to prevent the VF from sending another message while the PF is still processing the previous one.
