2024-12-03ixgbe: Correct BASE-BX10 compliance codeTore Amundsen
SFF-8472 (section 5.4 Transceiver Compliance Codes) defines bit 6 as BASE-BX10. Bit 6 means a value of 0x40 (decimal 64). The current value in the source code is 0x64, which appears to be a mix-up of hex and decimal values. A value of 0x64 (binary 01100100) incorrectly sets bit 2 (1000BASE-CX) and bit 5 (100BASE-FX) as well.

2024-12-03ixgbe: downgrade logging of unsupported VF API version to debugJacob Keller
The ixgbe PF driver logs an info message when a VF attempts to negotiate an API version which it does not support: VF 0 requested invalid api version 6 The ixgbevf driver attempts to load with mailbox API v1.5, which is required for best compatibility with other hosts such as the ESX VMWare PF. The Linux PF only supports API v1.4, and does not currently have support for the v1.5 API. The logged message can confuse users, as the v1.5 API is valid, but just happens to not currently be supported by the Linux PF. Downgrade the info message to a debug message, and fix the language to use 'unsupported' instead of 'invalid' to improve message clarity. Long term, we should investigate whether the improvements in the v1.5 API make sense for the Linux PF, and if so implement them properly. This may require yet another API version to resolve issues with negotiating IPSEC offload support.

2024-11-15ndo_fdb_add: Add a parameter to report whether notification was sentPetr Machata
Currently when FDB entries are added to or deleted from a VXLAN netdevice, the VXLAN driver emits one notification, including the VXLAN-specific attributes. The core however always sends a notification as well, a generic one. Thus two notifications are unnecessarily sent for these operations. A similar situation comes up with bridge driver, which also emits notifications on its own: # ip link add name vx type vxlan id 1000 dstport 4789 # bridge monitor fdb & [1] 1981693 # bridge fdb add de:ad:be:ef:13:37 dev vx self dst 192.0.2.1 de:ad:be:ef:13:37 dev vx dst 192.0.2.1 self permanent de:ad:be:ef:13:37 dev vx self permanent In order to prevent this duplicity, add a paremeter to ndo_fdb_add, bool *notified. The flag is primed to false, and if the callee sends a notification on its own, it sets it to true, thus informing the core that it should not generate another notification.

In prevision to add new UAPI for hwtstamp we will be limited to the struct ethtool_ts_info that is currently passed in fixed binary format through the ETHTOOL_GET_TS_INFO ethtool ioctl. It would be good if new kernel code already started operating on an extensible kernel variant of that structure, similar in concept to struct kernel_hwtstamp_config vs struct hwtstamp_config. Since struct ethtool_ts_info is in include/uapi/linux/ethtool.h, here we introduce the kernel-only structure in include/linux/ethtool.h.

2024-05-23Revert "ixgbe: Manual AN-37 for troublesome link partners for X550 SFI"Jacob Keller
This reverts commit 565736048bd5f9888990569993c6b6bfdf6dcb6d. According to the commit, it implements a manual AN-37 for some "troublesome" Juniper MX5 switches. This appears to be a workaround for a particular switch. It has been reported that this causes a severe breakage for other switches, including a Cisco 3560CX-12PD-S. The code appears to be a workaround for a specific switch which fails to link in SFI mode. It expects to see AN-37 auto negotiation in order to link. The Cisco switch is not expecting AN-37 auto negotiation. When the device starts the manual AN-37, the Cisco switch decides that the port is confused and stops attempting to link with it. This persists until a power cycle. A simple driver unload and reload does not resolve the issue, even if loading with a version of the driver which lacks this workaround. The authors of the workaround commit have not responded with clarifications, and the result of the workaround is complete failure to connect with other switches. This appears to be a case where the driver can either "correctly" link with the Juniper MX5 switch, at the cost of bricking the link with the Cisco switch, or it can behave properly for the Cisco switch, but fail to link with the Junipir MX5 switch. I do not know enough about the standards involved to clearly determine whether either switch is at fault or behaving incorrectly. Nor do I know whether there exists some alternative fix which corrects behavior with both switches. Revert the workaround for the Juniper switch.

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.

2024-03-28net: remove gfp_mask from napi_alloc_skb()Jakub Kicinski
__napi_alloc_skb() is napi_alloc_skb() with the added flexibility of choosing gfp_mask. This is a NAPI function, so GFP_ATOMIC is implied. The only practical choice the caller has is whether to set __GFP_NOWARN. But that's a false choice, too, allocation failures in atomic context will happen, and printing warnings in logs, effectively for a packet drop, is both too much and very likely non-actionable. This leads me to a conclusion that most uses of napi_alloc_skb() are simply misguided, and should use __GFP_NOWARN in the first place. We also have a "standard" way of reporting allocation failures via the queue stat API (qstats::rx-alloc-fail). The direct motivation for this patch is that one of the drivers used at Meta calls napi_alloc_skb() (so prior to this patch without __GFP_NOWARN), and the resulting OOM warning is the top networking warning in our fleet.

Added support for 1000BASE-BX, i.e. Gigabit Ethernet over single strand of single-mode fiber.

2023-12-13net: ethtool: pass a pointer to parameters to get/set_rxfh ethtool opsAhmed Zaki
The get/set_rxfh ethtool ops currently takes the rxfh (RSS) parameters as direct function arguments. This will force us to change the API (and all drivers' functions) every time some new parameters are added. This is part 1/2 of the fix, as suggested in [1]: - First simplify the code by always providing a pointer to all params (indir, key and func); the fact that some of them may be NULL seems like a weird historic thing or a premature optimization. It will simplify the drivers if all pointers are always present. - Then make the functions take a dev pointer, and a pointer to a single struct wrapping all arguments. The set_* should also take an extack.
