pull-request: bpf-next 2018-10-21
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Implement two new kind of BPF maps, that is, queue and stack
map along with new peek, push and pop operations, from Mauricio.
2) Add support for MSG_PEEK flag when redirecting into an ingress
psock sk_msg queue, and add a new helper bpf_msg_push_data() for
insert data into the message, from John.
3) Allow for BPF programs of type BPF_PROG_TYPE_CGROUP_SKB to use
direct packet access for __skb_buff, from Song.
4) Use more lightweight barriers for walking perf ring buffer for
libbpf and perf tool as well. Also, various fixes and improvements
from verifier side, from Daniel.
5) Add per-symbol visibility for DSO in libbpf and hide by default
global symbols such as netlink related functions, from Andrey.
6) Two improvements to nfp's BPF offload to check vNIC capabilities
in case prog is shared with multiple vNICs and to protect against
mis-initializing atomic counters, from Jakub.
7) Fix for bpftool to use 4 context mode for the nfp disassembler,
also from Jakub.
8) Fix a return value comparison in test_libbpf.sh and add several
bpftool improvements in bash completion, documentation of bpf fs
restrictions and batch mode summary print, from Quentin.
9) Fix a file resource leak in BPF selftest's load_kallsyms()
helper, from Peng.
10) Fix an unused variable warning in map_lookup_and_delete_elem(),
from Alexei.
11) Fix bpf_skb_adjust_room() signature in BPF UAPI helper doc,
from Nicolas.

Simplify bpf_perf_event_read_simple() a bit and fix up some minor
things along the way: the return code in the header is not of type
int but enum bpf_perf_event_ret instead. Once callback indicated
to break the loop walking event data, it also needs to be consumed
in data_tail since it has been processed already.
Moreover, bpf_perf_event_print_t callback should avoid void * as
we actually get a pointer to struct perf_event_header and thus
applications can make use of container_of() to have type checks.
The walk also doesn't have to use modulo op since the ring size is
required to be power of two.

Add options to run msg_push_data, this patch creates two more flags
in test_sockmap that can be used to specify the offset and length
of bytes to be added. The new options are --txmsg_start_push to
specify where bytes should be inserted and --txmsg_end_push to
specify how many bytes. This is analagous to the options that are
used to pull data, --txmsg_start and --txmsg_end.
In addition to adding the options tests are added to the test

This XDP selftest also contain a small TC-bpf component. It provoke
the generic-XDP bug fixed in previous commit.
The selftest itself shows how to do VLAN manipulation from XDP and TC.
The test demonstrate how XDP ingress can remove a VLAN tag, and how TC
egress can add back a VLAN tag.
This use-case originates from a production need by ISP (kviknet.dk),
who gets DSL-lines terminated as VLAN Q-in-Q tagged packets, and want
to avoid having an net_device for every end-customer on the box doing
the L2 to L3 termination.
The test-setup is done via a veth-pair and creating two network
namespaces (ns1 and ns2). The 'ns1' simulate the ISP network that are
loading the BPF-progs stripping and adding VLAN IDs. The 'ns2'
simulate the DSL-customer that are using VLAN tagged packets.
Running the script with --interactive, will simply not call the
cleanup function. This gives the effect of creating a testlab, that
the users can inspect and play with. The --verbose option will simply
request that the shell will print input lines as they are read, this
include comments, which in effect make the comments visible docs.

The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) sk_lookup_[tcp|udp] and sk_release helpers from Joe Stringer which allow
BPF programs to perform lookups for sockets in a network namespace. This would
allow programs to determine early on in processing whether the stack is
expecting to receive the packet, and perform some action (eg drop,
forward somewhere) based on this information.
2) per-cpu cgroup local storage from Roman Gushchin.
Per-cpu cgroup local storage is very similar to simple cgroup storage
except all the data is per-cpu. The main goal of per-cpu variant is to
implement super fast counters (e.g. packet counters), which don't require
neither lookups, neither atomic operations in a fast path.
The example of these hybrid counters is in selftests/bpf/netcnt_prog.c
3) allow HW offload of programs with BPF-to-BPF function calls from Quentin Monnet
4) support more than 64-byte key/value in HW offloaded BPF maps from Jakub Kicinski
5) rename of libbpf interfaces from Andrey Ignatov.
libbpf is maturing as a library and should follow good practices in
library design and implementation to play well with other libraries.
This patch set brings consistent naming convention to global symbols.
6) relicense libbpf as LGPL-2.1 OR BSD-2-Clause from Alexei Starovoitov
