sch_choke is classless qdisc so it does not define cl_ops. Therefore filter_list cannot be ever changed, being NULL all the time. Reason is this check in tc_ctl_tfilter: /* Is it classful? */ cops = q->ops->cl_ops; if (!cops) return -EINVAL; So remove this dead code. Signed-off-by:

Two different set_mac functions exists but stmmac_dwmac4_set_mac() is only used for enabling and never for disabling. So on dwmac4, the MAC RX/TX is never disabled. This patch add a generic function pointer set_mac() to stmmac_ops and replace all call to stmmac_set_mac/stmmac_dwmac4_set_mac by a call to this pointer. Since dwmac4_ops is const, set_mac cannot be modified after, and so dwmac4_ops is duplioacted like dwmac4_dma_ops. Signed-off-by:

Nikolay Aleksandrov says ==================== net: bridge: allow user-space to add ext learned entries This set adds the ability to add externally learned entries from user-space. For symmetry and proper function we need to allow SW entries to take over HW learned ones (similar to how HW can take over SW entries currently) which is needed for our use case (evpn) where we have pure SW ports and HW ports mixed in a single bridge. This does not play well with switchdev devices currently because there's no feedback when the entry is taken over, but this case has never worked anyway and feedback can be easily added when needed. Patch 02 simply allows to use NTF_EXT_LEARNED from user-space, we already have Quagga patches that make use of this functionality. ==================== Signed-off-by:

The NTF_EXT_LEARNED flag was added for switchdev and externally learned entries, but it can also be used for entries learned via a software in user-space which requires dynamic entries that do not expire. One such case that we have is with quagga and evpn which need dynamic entries but also require to age them themselves. Signed-off-by:

Chenbo Feng says: ==================== net: core: Two Helper function about socket information Introduce two eBpf helper function to get the socket cookie and socket uid for each packet. The helper function is useful when the *sk field inside sk_buff is not empty. These helper functions can be used on socket and uid based traffic monitoring programs. Change since V7: * change the user namespace of uid helper function to sock_net(sk)->user_ns Change since V6: * change the user namespace of uid helper function back to init_user_ns since in some situation, for example, pinned bpf object, the current user namespace is not always applicable. Change since V5: * Delete unnecessary blank lines in sample program. * Refine the variable orders in get_uid helper function. Change since V4: * Using current user namespace to get uid instead of using init_ns. * Add compiling setup of example program in to Makefile. * Change the name style of the example program binaries. Change since V3: * Fixed some typos and incorrect comments in sample program * replaced raw insns with BPF_STX_XADD and add it to libbpf.h * Use a temp dir as mount point instead and added a check for the user input string. * Make the get uid helper function returns the user namespace uid instead of kuid. * Return a overflowuid instead of 0 when no uid information is found. Change since V2: * Add a sample program to demostrate the usage of the helper function. * Moved the helper function proto invoking place. * Add function header into tools/include * Apply sk_to_full_sk() before getting uid. Change since V1: * Removed the unnecessary declarations and export command * resolved conflict with master branch. * Examine if the socket is a full socket before getting the uid. ==================== Signed-off-by:

Add a sample program to demostrate the possible usage of get_socket_cookie and get_socket_uid helper function. The program will store bytes and packets counting of in/out traffic monitored by iptables and store the stats in a bpf map in per socket base. The owner uid of the socket will be stored as part of the data entry. A shell script for running the program is also included. Acked-by:

Retrieve the socket cookie generated by sock_gen_cookie() from a sk_buff with a known socket. Generates a new cookie if one was not yet set.If the socket pointer inside sk_buff is NULL, 0 is returned. The helper function coud be useful in monitoring per socket networking traffic statistics and provide a unique socket identifier per namespace. Acked-by:

gcc points out that we are converting a 16-bit integer into a 32-bit little-endian type and assigning that to 16-bit little-endian will end up with a zero: drivers/scsi/qedf/drv_fcoe_fw_funcs.c: In function 'init_initiator_rw_fcoe_task': include/uapi/linux/byteorder/big_endian.h:32:26: error: large integer implicitly truncated to unsigned type [-Werror=overflow] t_st_ctx->read_write.rx_id = cpu_to_le32(FCOE_RX_ID); The correct solution appears to be to just use a 16-bit byte swap instead.

Yuval Mintz says: ==================== qed: Management interaction & feature changes All patches in this series either affect direct interaction with the management firmware, or changes logic relating to some values retrieved from it. Patch #1 revises the basic logic for sending messages to the management firmware and there completion, and is the most significant [at least code-wise] of the bunch. Patch #2 changes infrastrcure in a way that should better protect us form mistakes leading to stack corruption such as was fixed in bb480242 ("qed: Prevent stack corruption on MFW interaction"). Patch #3 corrects some update API endian issue [sent here as it would create conflicts with #2, and because it's lack would create a rather insignifcant problem]. Patch #4 removes some unnecessary logging, allowing cleaner forward compatibility with future management firmware versions. Patches #5, #6 slightly change the number of possible L2 queues in some scenarios, leading to the possibility of having more queues / VFS. ==================== Signed-off-by:

Align the driver feature distribution with the flow utilized by the management firmware - first reserve L2 queues for VFs and use all the remaining for the PF. The current distribution might lead to PFs with an enormous amount of queues, but at the same time leave us with insufficient resources for starting all VFs. Signed-off-by:

Management firmware and driver are meant to be both backward and forward compatibile with each other. If a new mangement firmware would work with an older driver, it's possible that driver would receive indications which are meaningless to it. That's perfectly acceptible from the firmware part - so no need to log such messages at default verbosity; That would only serve to confuse users. Signed-off-by:

The management firmware is running on a Big Endian processor, and when running on LE platform HW is configured to swap access to memory shared between management firmware and driver on 32-bit granulariy. As a result, for matters of simplicity most of the APIs between driver and management firmware are based on 32-bit variables. MAC settings are one exception, as driver needs to fill a byte array when indicating to management firmware that primary MAC has changed. Due to the swap, driver must make sure that the mac that was provided in byte-order would be translated into native order, otherwise after the swap the management firmware would read it swapped.

The driver interaction with management firmware involves a union of all the data-members relating to the commands the driver prepares. Current interface assumes the caller always passes such a union - but thats cumbersome as well as risky [chancing a stack corruption in case caller accidentally passes a smaller member instead of union]. Change implementation so that caller could pass a pointer to any of the members instead of the union. Signed-off-by:

Interaction of driver -> management firmware is based on a one-pending mailbox [per interface], and various mailbox commands need to be synchronized. Current scheme is messy, and there's a difficulty extending it as it deals differently with various commands as well as making assumption on the required behavior for load/unload requests. Drop the current scheme into a completion-list-based approach; Each flow would try sending the command when possible, allowing one flow to complete another flow's completion and relieve the mailbox before sending its own command.
