The hclgevf_free_vector function expects the caller to pass the vector_id to it, and hclgevf_put_vector pass vector to it now, which will cause vector allocation problem. This patch fixes it by converting vector into vector_id before calling hclgevf_free_vector. Fixes: e2cb1dec ("net: hns3: Add HNS3 VF HCL(Hardware Compatibility Layer) Support") Signed-off-by:

The payload of mailbox message is 16 byte and the value of HCLGE_MBX_MAX_ARQ_MSG_SIZE is 8. A message truncated problem will happen when mailbox message is converted to ARQ message. This patch replaces HCLGE_MBX_MAX_ARQ_MSG_SIZE with the size of ARQ message in hclgevf_mbx_handler to fix this problem. Fixes: b11a0bb2 ("net: hns3: Add mailbox support to VF driver") Signed-off-by:

Hardware only support tcp/udp/sctp l4 checksum offload, but the driver currently tell hardware to do l4 checksum offlad when l3 is IPv4 or IPv6, which may cause checksumm error.

Pre-1.7.2 NIC firmware does not support (and does not respond to) the "get speed" command which is sent by the 1.7.2 driver (for CN23XX-225 cards only) during modprobe. Due to a bug in older firmware (with respect to unknown commands), this unsupported command causes a cascade of errors that ends in a kernel panic. Fix it by making the sending of the "get speed" command conditional on the firmware version. Signed-off-by:

Willem de Bruijn says: ==================== sock cookie initializers Recent UDP GSO and SO_TXTIME features added new fields to cookie structs. When adding a field, all sites where a struct is initialized have to be updated, which is a lot of boilerplate. Alternatively, a field can be initialized selectively, but this is fragile. I introduced a bug in udp gso where an uninitialized field was read. See also fix commit ("9887cba1 ip: limit use of gso_size to udp"). Introduce initializers for structs ipcm(6)_cookie and sockc_cookie. patch 1..3 do exactly this. patch 4..5 make ipv4 and ipv6 handle cookies the same way and remove some boilerplate in doing so. patch 6 removes the udp gso branch that needed the above fix ==================== Signed-off-by: -

Now that ipc(6)->gso_size is correctly initialized in all callers of ip(6)_setup_cork, it is safe to unconditionally pass it to the cork. Link: http://lkml.kernel.org/r/20180619164752.143249-1-willemdebruijn.kernel@gmail.comSigned-off-by:

skb_shinfo(skb)->tx_flags is derived from sk->sk_tsflags, possibly after modification by __sock_cmsg_send, by calling sock_tx_timestamp. The IPv4 and IPv6 paths do this conversion differently. In IPv4, the individual protocols that support tx timestamps call this function and store the result in ipc.tx_flags. In IPv6, sock_tx_timestamp is called in __ip6_append_data. There is no need to store both tx_flags and ts_flags in the cookie as one is derived from the other. Convert when setting up the cork and remove the redundant field. This is similar to IPv6, only have the conversion happen only once per datagram, in ip(6)_setup_cork. Also change __ip6_append_data to match __ip_append_data. Only update tskey if timestamping is enabled with OPT_ID. The SOCK_.. test is redundant: only valid protocols can have non-zero cork->tx_flags. After this change the IPv4 and IPv6 logic is the same.

ipcm_cookie includes sockcm_cookie. Do the same for ipcm6_cookie. This reduces the number of arguments that need to be passed around, applies ipcm6_init to all cookie fields at once and reduces code differentiation between ipv4 and ipv6. Signed-off-by:

If we have an L3 master device, l3mdev_ip_rcv() will steal the skb, but we were returning NET_RX_SUCCESS from ip_rcv_finish_core() which meant that ip_list_rcv_finish() would keep it on the list. Instead let's move the l3mdev_ip_rcv() call into the caller, so that our response to a steal can be different in the single packet path (return NET_RX_SUCCESS) and the list path (forget this packet and continue).

The vendor guard Kconfig symbols for Cadence and Packet Engines use a "NET_" prefix, while all other vendor guards use a "NET_VENDOR_" prefix. Hence make them consistent with the rest, and add the missing trailing "S" for Packet Engines while at it. As these options don't directly affect the kernel build, and default to "y", this change has no impact on kernels built with existing (def)configs. Signed-off-by:

Moshe Shemesh says: ==================== Add configuration parameters support Add configuration parameters setting through devlink. Each device registers supported configuration parameters table. Each parameter can be either generic or driver specific. The user can retrieve data on these parameters by "devlink param show" command and can set new value to a parameter by "devlink param set" command. The parameters can be set in different configuration modes: runtime - set while driver is running, no reset required. driverinit - applied while driver initializes, requires restart driver by devlink reload command. permanent - written to device's non-volatile memory, hard reset required. The patches at the end of the patchset introduce few params that are using the introduced infrastructure on mlx4 and bnxt. Command examples and output: pci/0000:81:00.0: name internal_error_reset type generic values: cmode runtime value true cmode driverinit value true name max_macs type generic values: cmode driverinit value 128 name enable_64b_cqe_eqe type driver-specific values: cmode driverinit value true name enable_4k_uar type driver-specific values: cmode driverinit value false pci/0000:81:00.0: name internal_error_reset type generic values: cmode runtime value false cmode driverinit value true ==================== Signed-off-by: -

Create initial parameters table for mlx4. The table consists of two generic parameters and two driver-specific parameters. Generic: internal_err_reset - Enable reset device on internal errors. This parameter can be configured on mlx4 either on runtime or during driver initialization. max_macs - Max number of MACs per ETH port. For mlx4 this parameter value range is between 1 and 128. This parameter can be configured on mlx4 only during driver initialization. Driver specific: enable_64b_cqe_eqe - Enable 64 byte CQEs/EQEs when the FW supports it. This parameter can be configured on mlx4 only during driver initialization. enable_4k_uar - Enable using 4K UAR. This parameter can be configured on mlx4 only during driver initialization.
