2021-04-15Merge branch 'ehtool-fec-stats'David S. Miller
Jakub Kicinski says: ==================== ethtool: add standard FEC statistics This set adds uAPI for reporting standard FEC statistics, and implements it in a handful of drivers. The statistics are taken from the IEEE standard, with one extra seemingly popular but not standard statistics added. The implementation is similar to that of the pause frame statistics, user requests the stats by setting a bit (ETHTOOL_FLAG_STATS) in the common ethtool header of ETHTOOL_MSG_FEC_GET. Since standard defines the statistics per lane what's reported is both total and per-lane counters: # ethtool -I --show-fec eth0 FEC parameters for eth0: Configured FEC encodings: None Active FEC encoding: None Statistics: corrected_blocks: 256 Lane 0: 255 Lane 1: 1 uncorrectable_blocks: 145 Lane 0: 128 Lane 1: 17 v2: check for errors in mlx5 register access ==================== Signed-off-by: David S.

2021-04-15ethtool: add FEC statisticsJakub Kicinski
Similarly to pause statistics add stats for FEC. The IEEE standard mandates two sets of counters: - 30.5.1.1.17 aFECCorrectedBlocks - 30.5.1.1.18 aFECUncorrectableBlocks where block is a block of bits FEC operates on. Each of these counters is defined per lane (PCS instance). Multiple vendors provide number of corrected _bits_ rather than/as well as blocks. This set adds the 2 standard-based block counters and a extra one for corrected bits. Counters are exposed to user space via netlink in new attributes. Each attribute carries an array of u64s, first element is the total count, and the following ones are a per-lane break down. Much like with pause stats the operation will not fail when driver does not implement the get_fec_stats callback (nor can the driver fail the operation by returning an error). If stats can't be reported the relevant attributes will be empty. Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2021-04-15ethtool: fec_prepare_data() - jump to error handlingJakub Kicinski
Refactor fec_prepare_data() a little bit to skip the body of the function and exit on error. Currently the code depends on the fact that we only have one call which may fail between ethnl_ops_begin() and ethnl_ops_complete() and simply saves the error code. This will get hairy with the stats also being queried. No functional changes. Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>

The Atheros AR8031 and AR8033 expose different registers for SGMII/Fiber as well as the copper side of the PHY depending on the BT_BX_REG_SEL bit in the chip configure register. The driver assumes the copper side is selected on probe, but this might not be the case depending which page was last selected by the bootloader.

2021-04-14ice: manage interrupts during poll exitJesse Brandeburg
The driver would occasionally miss that there were outstanding descriptors to clean when exiting busy/napi poll. This issue has been in the code since the introduction of the ice driver. Attempt to "catch" any remaining work by triggering a software interrupt when exiting napi poll or busy-poll. This will not cause extra interrupts in the case of normal execution. This issue was found when running sfnt-pingpong, with busy poll enabled, and typically with larger I/O sizes like > 8192, the program would occasionally report > 1 second maximums to complete a ping pong.

2021-04-14ice: replace custom AIM algorithm with kernel's DIM libraryJacob Keller
The ice driver has support for adaptive interrupt moderation, an algorithm for tuning the interrupt rate dynamically. This algorithm is based on various assumptions about ring size, socket buffer size, link speed, SKB overhead, ethernet frame overhead and more. The Linux kernel has support for a dynamic interrupt moderation algorithm known as "dimlib". Replace the custom driver-specific implementation of dynamic interrupt moderation with the kernel's algorithm. The Intel hardware has a different hardware implementation than the originators of the dimlib code had to work with, which requires the driver to use a slightly different set of inputs for the actual moderation values, while getting all the advice from dimlib of better/worse, shift left or right. The change made for this implementation is to use a pair of values for each of the 5 "slots" that the dimlib moderation expects, and the driver will program those pairs when dimlib recommends a slot to use. The currently implementation uses two tables, one for receive and one for transmit, and the pairs of values in each slot set the maximum delay of an interrupt and a maximum number of interrupts per second (both expressed in microseconds). There are two separate kinds of bugs fixed by using DIMLIB, one is UDP single stream send was too slow, and the other is that 8K ping-pong was going to the most aggressive moderation and has much too high latency. The overall result of using DIMLIB is that we meet or exceed our performance expectations set based on the old algorithm.

2021-04-14ice: refactor interrupt moderation writesJesse Brandeburg
Introduce several new helpers for writing ITR and GLINT_RATE registers, and refactor the code calling them. This resulted in removal of several duplicate functions and rolled a bunch of simple code back into the calling routines. In particular this removes some code that was doing both a store and a set in a helper function, which seems better done as separate tasks in the caller (and generally takes less lines of code even with a tiny bit of repetition).

Normally, the bootloader will already initialize the MAC address registers of the ENETC and the driver will just use them or generate a random one, if it is not initialized. Add a new way to provide the MAC address: via device tree. Besides the usual 'mac-address' property, there is also the possibility to fetch it via a NVMEM provider. The sl28 board stores the MAC address in the SPI NOR flash OTP region. Having this will allow linux to fetch the MAC address from there without being dependent on the bootloader.

the commit 1ddc3229ad3c ("skbuff: remove some unnecessary operation in skb_segment_list()") introduces an issue very similar to the one already fixed by commit 53475c5dd856 ("net: fix use-after-free when UDP GRO with shared fraglist"). If the GSO skb goes though skb_clone() and pskb_expand_head() before entering skb_segment_list(), the latter will unshare the frag_list skbs and will release the old list. With the reverted commit in place, when skb_segment_list() completes, skb->next points to the just released list, and later on the kernel will hit UaF. Note that since commit e0e3070a9bc9 ("udp: properly complete L4 GRO over UDP tunnel packet") the critical scenario can be reproduced also receiving UDP over vxlan traffic with: NIC (NETIF_F_GRO_FRAGLIST enabled) -> vxlan -> UDP sink Attaching a packet socket to the NIC will cause skb_clone() and the tunnel decapsulation will call pskb_expand_head().
