When creating EQs to handle CQ completion events for the PF or for VFs, we create enough EQE entries to handle completions for the max number of CQs that can use that EQ. When SRIOV is activated, the max number of CQs a VF (or the PF) can obtain is its CQ quota (determined by the Hypervisor resource tracker). Therefore, when creating an EQ, the number of EQE entries that the VF should request for that EQ is the CQ quota value (and not the total number of CQs available in the FW). Under SRIOV, the PF, also must use its CQ quota, because the resource tracker also controls how many CQs the PF can obtain. Using the FW total CQs instead of the CQ quota when creating EQs resulted wasting MTT entries, due to allocating more EQEs than were needed.

In the VF driver, module parameter mlx4_log_num_mgm_entry_size was mistakenly overwritten -- and in a manner which overrode the device-managed flow steering option encoded in the parameter. log_num_mgm_entry_size is a global module parameter which affects all ConnectX-3 PFs installed on that host. If a VF changes log_num_mgm_entry_size, this will affect all PFs which are probed subsequent to the change (by disabling DMFS for those PFs).

Saeed Mahameed says: ==================== Mellanox mlx5e fixes for 4.11-rc1 This series includes some important bug fixes for mlx5e driver. Three misc fixes: From Mohamad, compilation fix on s390 system From Me, A fix for driver unload when switchdev mode is on. From Tariq, HW LRO frag size optimization for when build_skb is not used (striding RQ mode). Three CQE compression related fixes: Two fixes from Tariq and I, to correctly setup CQE compression parameters on driver load and on arbitrary user modifications. Last patch, fixes a very critical issue that was originally reported by Tom, where the driver reported csum errors or even page ref issues for when cqe compression is enabled and rapidly active. For your convenience this series was generated on top of net-next branch: 005c3490 ('Revert "ath10k: Search SMBIOS for OEM board file extension"') for -stable: net/mlx5e: Register/unregister vport representors on interface (for kernel >= 4.9) net/mlx5e: Do not reduce LRO WQE size when not using build_skb (for kernel >= 4.9) net/mlx5e: Fix broken CQE compression initialization (for kernel >= 4.9) net/mlx5e: Update MPWQE stride size when modifying CQE compress state (for kernel >= 4.7) net/mlx5e: Fix wrong CQE decompression (for kernel >= 4.7) ==================== Signed-off-by:

Tariq Toukan authored
In cqe compression with striding RQ, the decompression of the CQE field wqe_counter was done with a wrong wraparound value. This caused handling cqes with a wrong pointer to wqe (rx descriptor) and creating SKBs with wrong data, pointing to wrong (and already consumed) strides/pages. The meaning of the CQE field wqe_counter in striding RQ holds the stride index instead of the WQE index. Hence, when decompressing a CQE, wqe_counter should have wrapped-around the number of strides in a single multi-packet WQE. We dropped this wrap-around mask at all in CQE decompression of striding RQ. It is not needed as in such cases the CQE compression session would break because of different value of wqe_id field, starting a new compression session. Tested: ethtool -K ethxx lro off/on ethtool --set-priv-flags ethxx rx_cqe_compress on super_netperf 16 {ipv4,ipv6} -t TCP_STREAM -m 50 -D verified no csum errors and no page refcount issues.

When the admin enables/disables cqe compression, updating mpwqe stride size is required: CQE compress ON ==> stride size = 256B CQE compress OFF ==> stride size = 64B This is already done on driver load via mlx5e_set_rq_type_params, all we need is just to call it on arbitrary admin changes of cqe compression state via priv flags or when changing timestamping state (as it is mutually exclusive with cqe compression). This bug introduces no functional damage, it only makes cqe compression occur less often, since in ConnectX4-LX CQE compression is performed only on packets smaller than stride size. Tested: ethtool --set-priv-flags ethxx rx_cqe_compress on pktgen with 64 < pkt size < 256 and netperf TCP_STREAM (IPv4/IPv6) verify `ethtool -S ethxx | grep compress` are advancing more often (rapidly) Fixes: 7219ab34 ("net/mlx5e: CQE compression") Signed-off-by: -
Tariq Toukan authored
Some of RQ type parameters are derived from CQE compression state flag, CQE compression flag was initialized only after RQ type parameters setup. This leads to load RQ with stride size smaller than what we want for when CQE compression is on. This bug introduces no functional damage, it only makes CQE compression occur less often, since in ConnectX4-LX CQE compression is performed only on packets smaller than stride size. Fix this by marking default status of CQE compression in PFLAG prior to calling mlx5e_set_rq_priv_params(), as it inits some fields based on it. Tested: load driver on systems where rx CQE compress will be on (MH) pktgen with 64 < pkt size < 256 and netperf TCP_STREAM (IPv4/IPv6) verify `ethtool -S ethxx | grep compress` are advancing more often (rapidly) Fixes: 2fc4bfb7 ("net/mlx5e: Dynamic RQ type infrastructure") Signed-off-by:

Saeed Mahameed authored
Currently vport representors are added only on driver load and removed on driver unload. Apparently we forgot to handle them when we added the seamless reset flow feature. This caused to leave the representors netdevs alive and active with open HW resources on pci shutdown and on error reset flows. To overcome this we move their handling to interface attach/detach, so they would be cleaned up on shutdown and recreated on reset flows.

Found that when randomized tcp offsets are enabled (by default) TCP client can still start new connections without them. Later, if server does active close and re-uses sockets in TIME-WAIT state, new SYN from client can be rejected on PAWS check inside tcp_timewait_state_process(), because either tw_ts_recent or rcv_tsval doesn't really have an offset set. Here is how to reproduce it with LTP netstress tool: netstress -R 1 & netstress -H 127.0.0.1 -lr 1000000 -a1 [...] < S seq 1956977072 win 43690 TS val 295618 ecr 459956970 > . ack 1956911535 win 342 TS val 459967184 ecr 1547117608 < R seq 1956911535 win 0 length 0 +1. < S seq 1956977072 win 43690 TS val 296640 ecr 459956970 > S. seq 657450664 ack 1956977073 win 43690 TS val 459968205 ecr 296640 Fixes: 95a22cae ("tcp: randomize tcp timestamp offsets for each connection") Signed-off-by: -

All current users of <linux/if.h> are very likely to be including <sys/socket.h> already because the latter is the sole provider of struct sockaddr definition in libc, so adding a uapi header with a definition of struct sockaddr would create a potential conflict with <sys/socket.h>. Replacing struct sockaddr in the definition of struct ifreq with a different type would create a potential incompatibility with current users of struct ifreq who might rely on ifru_addr et al members being of type struct sockaddr.

This patch adds glue-code that allows the EMAC driver to interface with the existing dt-supported PHYs in drivers/net/phy. Because currently, the emac driver maintains a small library of supported phys for in a private phy.c file located in the drivers directory. The support is limited to mostly single ethernet transceiver like the: CIS8201, BCM5248, ET1011C, Marvell 88E1111 and 88E1112, AR8035. However, routers like the Netgear WNDR4700 and Cisco Meraki MX60(W) have a 5-port switch (AR8327N) attached to the EMAC. The switch chip is supported by the qca8k mdio driver, which uses the generic phy library. Another reason is that PHYLIB also supports the BCM54610, which was used for the Western Digital My Book Live. This will now also make EMAC select PHYLIB. Signed-off-by:

This allows the hash table to be sized based on the current memory usage of the guest, rather than the maximum possible memory usage. - Implementation of optprobes (kprobe optimisation) for powerpc. In addition there's the topic branch shared with the KVM tree, which includes support for guests to use the Radix MMU on Power9.
