Document the parameter. v3: Document type of parameter, and valid range Add break statements to default clause of switch Directly use ctx->val.vu8 v4: Consistently use devlink, not a mix of devlink and dl. Fix allocation of devlink priv Remove upper case from parameter name Make mask 16 bit wide. v5: Back to using the parameter name ATU_hash v6: Rebase net-next/master ==================== Signed-off-by: David S.

Some of the marvell switches have bits controlling the hash algorithm the ATU uses for MAC addresses. In some industrial settings, where all the devices are from the same manufacture, and hence use the same OUI, the default hashing algorithm is not optimal. Allow the other algorithms to be selected via devlink. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S. Miller <davem@davemloft.net>

Add plumbing to allow DSA drivers to register parameters with devlink. To keep with the abstraction, the DSA drivers pass the ds structure to these helpers, and the DSA core then translates that to the devlink structure associated to the device.

Florian Fainelli says: ==================== net: dsa: b53: Add support for MDB This patch series adds support for programming multicast database entries on b53 and bcm_sf2. This is extracted from a previously submitted series that added managed mode support, but these patches are usable in isolation.

Florian Fainelli authored
In preparation for supporting IGMP snooping with or without the use of a bridge, add support within b53_common.c to program the ARL entries for multicast operations. The key difference is that a multicast ARL entry is comprised of a bitmask of enabled ports, instead of a port number.

Matteo Croce says: ==================== mvpp2 improvements in rx path Refactor some code in the RX path to allow prefetching some data from the packet header. The first patch is only a refactor, the second one reduces the data synced, while the third one adds the prefetch. The packet rate improvement with the second patch is very small (1606 => 1620 kpps), while the prefetch bumps it up by 14%: 1620 => 1853 kpps. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Matteo Croce authored
When receiving traffic, eth_type_trans() is high up on the perf top list, because it's the first function which access the packet data. Move the DMA unmap a bit higher, and put a prefetch just after it, so we have more time to load the data into the cache. The packet rate increase is about 14% with a tc drop test: 1620 => 1853 kpps Signed-off-by: Matteo Croce <mcroce@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Since commit 0394a63a ("net: dsa: enable and disable all ports") the dsa core disables all unused ports of a switch. In this case disabling ports with numbers higher than QCA8K_NUM_PORTS causes that some switch registers are overwritten with incorrect content. To fix this, initialize the dsa_switch->num_ports with correct number of ports.

Daniel Borkmann says: ==================== pull-request: bpf-next 2019-10-27 The following pull-request contains BPF updates for your *net-next* tree. We've added 52 non-merge commits during the last 11 day(s) which contain a total of 65 files changed, 2604 insertions(+), 1100 deletions(-). The main changes are: 1) Revolutionize BPF tracing by using in-kernel BTF to type check BPF assembly code. The work here teaches BPF verifier to recognize kfree_skb()'s first argument as 'struct sk_buff *' in tracepoints such that verifier allows direct use of bpf_skb_event_output() helper used in tc BPF et al (w/o probing memory access) that dumps skb data into perf ring buffer. Also add direct loads to probe memory in order to speed up/replace bpf_probe_read() calls, from Alexei Starovoitov. 2) Big batch of changes to improve libbpf and BPF kselftests. Besides others: generalization of libbpf's CO-RE relocation support to now also include field existence relocations, revamp the BPF kselftest Makefile to add test runner concept allowing to exercise various ways to build BPF programs, and teach bpf_object__open() and friends to automatically derive BPF program type/expected attach type from section names to ease their use, from Andrii Nakryiko. 3) Fix deadlock in stackmap's build-id lookup on rq_lock(), from Song Liu. 4) Allow to read BTF as raw data from bpftool. Most notable use case is to dump /sys/kernel/btf/vmlinux through this, from Jiri Olsa. 5) Use bpf_redirect_map() helper in libbpf's AF_XDP helper prog which manages to improve "rx_drop" performance by ~4%., from Björn Töpel. 6) Fix to restore the flow dissector after reattach BPF test and also fix error handling in bpf_helper_defs.h generation, from Jakub Sitnicki. 7) Improve verifier's BTF ctx access for use outside of raw_tp, from Martin KaFai Lau. 8) Improve documentation for AF_XDP with new sections and to reflect latest features, from Magnus Karlsson. 9) Add back 'version' section parsing to libbpf for old kernels, from John Fastabend. 10) Fix strncat bounds error in libbpf's libbpf_prog_type_by_name(), from KP Singh. 11) Turn on -mattr=+alu32 in LLVM by default for BPF kselftests in order to improve insn coverage for built BPF progs, from Yonghong Song. 12) Misc minor cleanups and fixes, from various others. ==================== Signed-off-by: David S.

Problem is that nf_conntrack_confirm() uses the old ct: static inline int nf_conntrack_confirm(struct sk_buff *skb) { struct nf_conn *ct = (struct nf_conn *)skb_nfct(skb); int ret = NF_ACCEPT; if (ct) { if (!nf_ct_is_confirmed(ct)) ret = __nf_conntrack_confirm(skb); if (likely(ret == NF_ACCEPT)) nf_ct_deliver_cached_events(ct); /* This ct has refcount 0! */ } return ret; } As of "netfilter: conntrack: free extension area immediately", we can't access conntrack extensions in this case. To fix this, make sure we check the dying bit presence before attempting to get the eache extension.

Even out Rx performance across MTU sizes by changing from full skb allocations to page-based frag allocations. The device supports a form of scatter-gather in the Rx path, so we can set up a number of pages for each descriptor, all of which are easier to alloc and pass around than the standard kzalloc'd buffer. An skb is wrapped around the pages while processing the received packets, and pages are recycled as needed, or left alone if they weren't used in the Rx.
