This patch adds support for allocating, configuring, and freeing Tx/Rx ring resources. With these changes in place the descriptor queues are in a state where they are ready to transmit or receive if provided buffers. This also adds the transmit and receive fastpath and interrupt handlers. With this code in place the network device is now able to send and receive frames over the network interface using a single queue. Signed-off-by:

This patch adds the basic defines and structures needed by the PF for operation. With this it is possible to bring up the interface, but without being able to configure any of the filters on the interface itself. Add skeleton for a function pointers. Signed-off-by:

Eric reported that syzkaller triggered a splat in tcp_cleanup_ulp() where assertion sock_owned_by_me() failed. This happened through inet_csk_prepare_forced_close() first releasing the socket lock, then calling into tcp_done(newsk) which is called after the inet_csk_prepare_forced_close() and therefore without the socket lock held. The sock_owned_by_me() assertion can generally be removed as the only place where tcp_cleanup_ulp() is called from now is out of inet_csk_destroy_sock() -> sk->sk_prot->destroy() where socket is in dead state and unreachable. Therefore, add a comment why the check is not needed instead. Fixes: 8b9088f8 ("tcp, ulp: enforce sock_owned_by_me upon ulp init and cleanup") Reported-by:

Yunsheng Lin says: ==================== Some cleanup and bugfix for desc filling When retransmiting packets, skb_cow_head which is called in hns3_set_tso may clone a new header. And driver will clear the checksum of the header after doing DMA map, so HW will read the old header whose L3 checksum is not cleared and calculate a wrong L3 checksum. Also When sending a big fragment using multiple buffer descriptor, hns3 does one maping, but do multiple unmapping when tx is done, which may cause unmapping problem. This patchset does some cleanup before fixing the above problem. ==================== Signed-off-by: -

When sending a big fragment using multiple buffer descriptor, hns3 does one maping, but do multiple unmapping when tx is done, which may cause unmapping problem. To fix it, this patch makes sure the value of desc_cb.length of the non-first bd is zero. If desc_cb.length is zero, we do not unmap the buffer.

To solve the L3 checksum error problem which happens when driver does not clear L3 checksum, DMA map should be done after calling skb_cow_head. This patch moves DMA map into hns3_fill_desc to ensure that DMA map is done after calling skb_cow_head. Fixes: 76ad4f0e ("net: hns3: Add support of HNS3 Ethernet Driver for hip08 SoC") Signed-off-by:

Rahul Verma authored
Align the use of local PTT to propagate through the qed_mcp* API's. Global ptt should not be used. Register access should be done through layers. Register address is mapped into a PTT, PF translation table. Several interface functions require a PTT to direct read/write into register. There is a pool of PTT maintained, and several PTT are used simultaneously to access device registers in different flows. Same PTT should not be used in flows that can run concurrently. To avoid running out of PTT resources, too many PTT should not be acquired without releasing them. Every PF has a global PTT, which is used throughout the life of PF, in most important flows for register access. Generic functions acquire the PTT locally and release after the use. This patch aligns the use of Global PTT and Local PTT accordingly. Signed-off-by: -

David Ahern says: ==================== net: Kernel side filtering for route dumps Implement kernel side filtering of route dumps by protocol (e.g., which routing daemon installed the route), route type (e.g., unicast), table id and nexthop device. iproute2 has been doing this filtering in userspace for years; pushing the filters to the kernel side reduces the amount of data the kernel sends and reduces wasted cycles on both sides processing unwanted data. These initial options provide a huge improvement for efficiently examining routes on large scale systems. v2 - better handling of requests for a specific table. Rather than walking the hash of all tables, lookup the specific table and dump it - refactor mr_rtm_dumproute moving the loop over the table into a helper that can be invoked directly - add hook to return NLM_F_DUMP_FILTERED in DONE message to ensure it is returned even when the dump returns nothing ==================== Signed-off-by: -

Unlike IPv6, IPv4 does not have routes marked with RTF_PREFIX_RT. If the flag is set in the dump request, just return. In the process of this change, move the CLONE check to use the new filter flags. Signed-off-by:

David Ahern authored
Update parsing of route dump request to enable kernel side filtering. Allow filtering results by protocol (e.g., which routing daemon installed the route), route type (e.g., unicast), table id and nexthop device. These amount to the low hanging fruit, yet a huge improvement, for dumping routes. ip_valid_fib_dump_req is called with RTNL held, so __dev_get_by_index can be used to look up the device index without taking a reference. From there filter->dev is only used during dump loops with the lock still held. Set NLM_F_DUMP_FILTERED in the answer_flags so the user knows the results have been filtered should no entries be returned. Signed-off-by:

Add struct fib_dump_filter for options on limiting which routes are returned in a dump request. The current list is table id, protocol, route type, rtm_flags and nexthop device index. struct net is needed to lookup the net_device from the index.

With dump filtering we need a way to ensure the NLM_F_DUMP_FILTERED flag is set on a message back to the user if the data returned is influenced by some input attributes. Normally this can be done as messages are added to the skb, but if the filter results in no data being returned, the user could be confused as to why. This patch adds answer_flags to the netlink_callback allowing dump handlers to set the NLM_F_DUMP_FILTERED at a minimum in the NLMSG_DONE message ensuring the flag gets back to the user. The netlink_callback space is initialized to 0 via a memset in __netlink_dump_start, so init of the new answer_flags is covered. Signed-off-by:

Daniel Borkmann says: ==================== pull-request: bpf-next 2018-10-16 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Convert BPF sockmap and kTLS to both use a new sk_msg API and enable sk_msg BPF integration for the latter, from Daniel and John. 2) Enable BPF syscall side to indicate for maps that they do not support a map lookup operation as opposed to just missing key, from Prashant. 3) Add bpftool map create command which after map creation pins the map into bpf fs for further processing, from Jakub. 4) Add bpftool support for attaching programs to maps allowing sock_map and sock_hash to be used from bpftool, from John. 5) Improve syscall BPF map update/delete path for map-in-map types to wait a RCU grace period for pending references to complete, from Daniel. 6) Couple of follow-up fixes for the BPF socket lookup to get it enabled also when IPv6 is compiled as a module, from Joe. 7) Fix a generic-XDP bug to handle the case when the Ethernet header was mangled and thus update skb's protocol and data, from Jesper. 8) Add a missing BTF header length check between header copies from user space, from Wenwen. 9) Minor fixups in libbpf to use __u32 instead u32 types and include proper perf_event.h uapi header instead of perf internal one, from Yonghong. 10) Allow to pass user-defined flags through EXTRA_CFLAGS and EXTRA_LDFLAGS to bpftool's build, from Jiri. 11) BPF kselftest tweaks to add LWTUNNEL to config fragment and to install with_addr.sh script from flow dissector selftest, from Anders. ==================== Signed-off-by: -

Eric Dumazet says: ==================== tcp: second round for EDT conversion First round of EDT patches left TCP stack in a non optimal state. - High speed flows suffered from loss of performance, addressed by the first patch of this series. - Second patch brings pacing to the current state of networking, since we now reach ~100 Gbit on a single TCP flow. - Third patch implements a mitigation for scheduling delays, like the one we did in sch_fq in the past. - Fourth patch removes one special case in sch_fq for ACK packets. - Fifth patch removes a serious perfomance cost for TCP internal pacing. We should setup the high resolution timer only if really needed. - Sixth patch fixes a typo in BBR. - Last patch is one minor change in cdg congestion control. Neal Cardwell also has a patch series fixing BBR after EDT adoption. ==================== Signed-off-by: -
