For any open socket file descriptor sock->sk->sk_wq->wait will always point to sock->wq->wait. That means we can do the shorter dereference and removal a NULL check and don't have to not worry about any RCU protection. Signed-off-by:

Since driver is devicetree-based, all device type and charateristic can be determined by the compatible string and its data. It's unnecessary to create another dependent function to check chip ID and then decide whether the specific funciton is being supported on a certain device. It can be totally replaced by the existing flag, so a cleanup is made by removing the function and the only user, HWLRO. MT2701 also have a missing HWLRO support in old code, so add it the same patch. Signed-off-by:

Commit 5f81880d ("sysfs, kobject: allow creating kobject belonging to arbitrary users") incorrectly changed the argument passed as the parent parameter when calling sysfs_add_file_mode_ns().

Saeed Mahameed says: ==================== mlx5e-updates-2018-07-27 (Vxlan updates) This series from Gal and Saeed provides updates to mlx5 vxlan implementation. Gal, started with three cleanups to reflect the actual hardware vxlan state - reflect 4789 UDP port default addition to software database - check maximum number of vxlan UDP ports - cleanup an unused member in vxlan work Then Gal provides performance optimization by replacing the vxlan radix tree with a hash table. Measuring mlx5e_vxlan_lookup_port execution time: Radix Tree Hash Table --------------- ------------ ------------ Single Stream 161 ns 79 ns (51% improvement) Multi Stream 259 ns 136 ns (47% improvement) Measuring UDP stream packet rate, single fully utilized TX core: Radix Tree: 498,300 PPS Hash Table: 555,468 PPS (11% improvement) Next, from Saeed, vxlan refactoring to allow sharing the vxlan table between different mlx5 netdevice instances like PF and VF representors, this is done by making mlx5 vxlan interface more generic and decoupling it from PF netdevice structures and logic, then moving it into mlx5 core as a low level interface so it can be used by VF representors, which is illustrated in the last patch of the serious. ==================== Signed-off-by: -

There are two problems in this test case: - When indexing in bash associative array, the subscript is interpreted as string, not as a variable name to be expanded. - The keys stored to t0s and t1s are not DSCP values, but priority + base (i.e. the logical DSCP value, not the full bitfield value). In combination these two bugs conspire to make the test just work, except it doesn't really test anything and always passes. Fix the above two problems in obvious manner. Signed-off-by:

If an invalid MTU value is set through rtnetlink return extra error information instead of putting message in kernel log. For other cases where there is no visible API, keep the error report in the log. Example: # ip li set dev enp12s0 mtu 10000 Error: mtu greater than device maximum. # ifconfig enp12s0 mtu 10000 SIOCSIFMTU: Invalid argument # dmesg | tail -1 [ 2047.795467] enp12s0: mtu greater than device maximum Signed-off-by:

As Ido's suggestion, this patch is to add a selftest for directed broadcast forwarding with vrf. It does the assertion by checking the src IP of the echo-reply packet in ping_test_from. Signed-off-by:

Xin Long authored
This patch implements the feature described in rfc1812#section-5.3.5.2 and rfc2644. It allows the router to forward directed broadcast when sysctl bc_forwarding is enabled. Note that this feature could be done by iptables -j TEE, but it would cause some problems: - target TEE's gateway param has to be set with a specific address, and it's not flexible especially when the route wants forward all directed broadcasts. - this duplicates the directed broadcasts so this may cause side effects to applications. Besides, to keep consistent with other os router like BSD, it's also necessary to implement it in the route rx path. Note that route cache needs to be flushed when bc_forwarding is changed.

Dan Murphy's patch fixes the path to a file in the comment of the CAN Error Message Frame Mask structure. A patch by Colin Ian King fixes a typo in the cc770 driver. The next patch is by me an sorts the Kconfigand Makefile entries of the CAN-USB driver subdir alphabetically. The patch by Jakob Unterwurzacher adds support for the UCAN USB-CAN adapter. YueHaibing's patch replaces a open coded skb_put()+memset() by skb_put_zero() in the CAN-dev infrastructure. Zhu Yi provides a patch to enable multi-queue CAN devices. Three patches by Luc Van Oostenryck fix the return value of several driver's xmit function, I contribute a patch for the a fourth driver. Fabio Estevam's patch switches the flexcan driver to SPDX identifier. Two patches by Jia-Ju Bai replace the mdelay() by a usleep_range() in the sja1000 drivers. The next 6 patches are by Anssi Hannula and refactor the xilinx CAN driver and add support for the xilinx CAN FD core. A patch by Gustavo A. R. Silva adds fallthrough annotation to the peak_usb driver. 5 patches by Stephane Grosjean for the peak CANFD driver do some cleanups and provide more improvements for further firmware releases. The remaining 13 patches are by Jimmy Assarsson and the first clean up the kvaser_usb driver, so that the later patches add support for the Kvaser USB hydra family. ==================== Signed-off-by:

Doron Roberts-Kedes authored
The current code is problematic because the iov_iter is reverted and never advanced in the non-error case. This patch skips the revert in the non-error case. This patch also fixes the amount by which the iov_iter is reverted. Currently, iov_iter is reverted by size, which can be greater than the amount by which the iter was actually advanced. Instead, only revert by the amount that the iter was advanced. Fixes: 47187998 ("tls: Fix zerocopy_from_iter iov handling") Signed-off-by:

On year ago Rob Herring wanted to remove the data pointer from the device_node structure[1]. The mvneta driver seemed to be the only one which used (abused ?) it. However, the proposal of Rob to remove this pointer from the driver introduced a regression, and I tested and fixed an alternative way, but it was never submitted as a proper patch. Now here it is: Instead of using the device_node structure ->data pointer, we store the BM private data as the driver data of the BM platform_device. The core mvneta code can retrieve it by doing a lookup on which platform_device corresponds to the BM device tree node using of_find_device_by_node(), and get its driver data [1]https://www.spinics.net/lists/netdev/msg445197.htmlSigned-off-by:

It is incorrect to enable TX/RX queues (call by mvneta_port_up()) for port without link. Indeed MTU change for interface without link causes TX queues to stuck. Fixes: c5aff182 ("net: mvneta: driver for Marvell Armada 370/XP network unit") Signed-off-by:

The mvneta Ethernet driver is used on a few different Marvell SoCs. Some SoCs have per cpu interrupts for Ethernet events. Some SoCs have a single interrupt, independent of the CPU. The driver handles this by having a per CPU napi structure when there are per CPU interrupts, and a global napi structure when there is a single interrupt. When the napi core calls mvneta_poll(), it passes the napi instance. This was not being propagated through the call chain, and instead the per-cpu napi instance was passed to napi_gro_receive() call. This breaks when there is a single global napi instance. Signed-off-by:
