after act_csum computes the checksum on skbs carrying GSO TCP/UDP packets, subsequent segmentation fails because skb_needs_check(skb, true) returns true. Because of that, skb_warn_bad_offload() is invoked and the following message is displayed: WARNING: CPU: 3 PID: 28 at net/core/dev.c:2553 skb_warn_bad_offload+0xf0/0xfd <...> [<ffffffff8171f486>] skb_warn_bad_offload+0xf0/0xfd [<ffffffff8161304c>] __skb_gso_segment+0xec/0x110 [<ffffffff8161340d>] validate_xmit_skb+0x12d/0x2b0 [<ffffffff816135d2>] validate_xmit_skb_list+0x42/0x70 [<ffffffff8163c560>] sch_direct_xmit+0xd0/0x1b0 [<ffffffff8163c760>] __qdisc_run+0x120/0x270 [<ffffffff81613b3d>] __dev_queue_xmit+0x23d/0x690 [<ffffffff81613fa0>] dev_queue_xmit+0x10/0x20 Since GSO is able to compute checksum on individual segments of such skbs, we can simply skip mangling the packet.

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: NDavid S.

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.

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: NDavid S.

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.

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.

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].

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.
