40GbE Intel Wired LAN Driver Updates 2019-10-25
This series contains updates to i40e only. Several are fixes that could
go to 'net', but were intended for 'net-next'.
Sylwia changes how the driver function to read the NVM module data, so
that it is able to read the LLDP agent configuration to allow for
persistent LLDP.
Jaroslaw resolves an issue where the incorrect FEC settings were being
displayed in ethtool, by setting the proper FEC bits.
Piotr moves the hardware flags detection into a separate function, so
that the specific flags can be set based on the MAC and NVM. Also
extends the PHY access function to include a command flag to let the
firmware know it should not change the page while accessing a OSFP module.
Updates the driver to display the driver and firmware version when in
recovery mode.
Aleksandr refactored the VF MAC filters accounting since an untrusted
VF was able to delete but not add a MAC filter, so refactor the code to
have more consistency and improved logging.
Nicholas updates the driver to use a default interval of 50 usecs,
instead of the current 100 usecs which was causing some regression
performance issues.
Damian resolved LED blinking issues for X710T*L devices by adding
specific flows for these devices in the LED operations.
Navid Emamdoost found where allocated memory is not being properly freed
upon a failure in setting up MAC VLANs, so added the missing kfree().
v2: Dropped patches 2 & 6 from the original series while we wait for the
author to respond to community feedback.

mvpp2 improvements in rx path
Refactor some code in the RX path to allow prefetching some data from the

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.

3. nf_ct_resolve_clash() puts skb->nfct (the "losing" entry).
4. this entry now has a refcount of 0 and is freed to SLAB_TYPESAFE_BY_RCU
kmem cache.
skb->nfct has been replaced by the one found in the hash.
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;

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.

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.
