Commit "net: bpf: make eBPF interpreter images read-only" has changed bpf_prog to be vmalloc()ed but never handled some of the errors paths of the old code. On error within sk_attach_filter (which userspace can easily trigger), we'd kfree() the vmalloc()ed memory, and leak the internal bpf_work_struct.

Change from v3 to v4 - use "unsigned int" instead of "unsigned" Change from v2 to v3 - fixed alignment requirement for ARM and NO-ARM platform Change from v1 to v2. - Change num_tx_queue to unsigned int - Avoid block non-dt platform - remove call netif_set_real_num_rx_queues - seperate multi queue patch two part, one is tx and rx handle, with fixed queue 0 then other one is initilized multiqueue - use two difference alignment for tx and rx path ==================== Signed-off-by: NDavid S.

i.MX6sx enet has below clocks for user config: clk_ipg: ipg_clk_s, ipg_clk_mac0_s, 66Mhz clk_ahb: enet system clock, it is enet AXI clock for imx6sx. For imx6sx, it alos is the clock source of interrupt coalescing. The clock range: 200Mhz ~ 266Mhz. clk_ref: refrence clock for tx and rx. For imx6sx enet RGMII mode, the refrence clock is 125Mhz coming from internal PLL or external. In i.MX6sx-arm2 board, the clock is from internal PLL. clk_ref is optional, depends on board. clk_enet_out: The clock can be output from internal PLL. It can supply 50Mhz clock for phy. clk_enet_out is optional, depends on chip and board. clk_ptp: 1588 ts clock. It is optional, depends on chip.

Sathya Perla says: ==================== be2net: patch set Patch 1 fixes some minor issues with log messages in be2net. Patch 2 replaces strcpy() calls with strlcpy() to avoid possible buffer overflow. Patch 3 improves the RX buffer posting scheme for jumbo frames. Patch 4 replaces the use of v0 of SET_FLOW_CONTROL cmd with v1 to receive a definitive completion status from FW. Patch 5 adds support for ethtool "-m" ethtool option. Patch 6 fixes port-type reporting via ethtool get_settings for QSFP/SFP+ interfaces. Patch 7 fixes the usage of MODIFY_EQD FW cmd to target a max of 8 EQs on Lancer chip. Patch 8 enables PCIe error reporting even for VFs. Pls consider applying this patch set to net-next. Thanks. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

由 Ajit Khaparde 提交于
In the RX path, the driver currently consumes upto 64 (budget) packets in one NAPI sweep. When the size of the packet received is larger than a fragment size (2K), more than one fragment is consumed for each packet. As the driver currently posts a max of 64 fragments, all the consumed fragments may not be replenished. This can cause avoidable drops in RX path. This patch fixes this by posting a max(consumed_frags, 64) frags. This is done only when there are atleast 64 free slots in the RXQ.

The driver can safely ignore async events from FW it's not interested in. 3) Reword a log message for better readability to say that SRIOV "is disabled" rather than "not supported".

Currently we have 2 pkt_type_offset functions doing the same thing and spread across the architecture files. Remove those and replace them with a PKT_TYPE_OFFSET macro helper which gets the constant value from a zero sized sk_buff member right in front of the bitfield with offsetof. This new offset marker does not change size of struct sk_buff.

Now that we introduced an additional multiplexing/demultiplexing layer with commit 3e8a72d1 ("net: dsa: reduce number of protocol hooks") that lives within the DSA code, we no longer need to have a given switch driver tag_protocol be an actual ethertype value, instead, we can replace it with an enum: dsa_tag_protocol. Do this replacement in the drivers, which allows us to get rid of the cpu_to_be16()/htons() dance, and remove ETH_P_BRCMTAG since we do not need it anymore.
