Hi Peter, Dave,
this patch set is a follow up to the discussion:

It turned out to be simpler than what we discussed.
Patches 1-3 is a bpf-side prep for the main patch 4
that adds bpf program as an overflow_handler to sw and hw perf_events.
Peter, please review.
Introduce BPF_PROG_TYPE_PERF_EVENT programs that can be attached to
HW and SW perf events (PERF_TYPE_HARDWARE and PERF_TYPE_SOFTWARE
correspondingly in uapi/linux/perf_event.h)
The program visible context meta structure is
struct bpf_perf_event_data {
struct pt_regs regs;

The verifier supported only 4-byte metafields in
struct __sk_buff and struct xdp_md. The metafields in upcoming
struct bpf_perf_event are 8-byte to match register width in struct pt_regs.
Teach verifier to recognize 8-byte metafield access.
The patch doesn't affect safety of sockets and xdp program

Add a simple userpace program to demonstrate the new API to attach eBPF

eBPF programs used in this context are expected to either return 1 to
let the packet pass, or != 1 to drop them. The programs have access to
the full skb, including the MAC headers.
This patch adds two sets of eBPF program pointers to struct cgroup.
One for such that are directly pinned to a cgroup, and one for such
that are effective for it.
To illustrate the logic behind that, assume the following example

Operations on the register are then performed as follows:

Advanced JIT compilers and translators may want to use
eBPF verifier as a base for parsers or to perform custom
checks and validations.
Add ability for external users to invoke the verifier
and provide callbacks to be invoked for every intruction
checked. For now only add most basic callback for
Teach the verifier to recognize that xoring a register with
itself makes it a constant (0).

Add cls_bpf support for the TCA_CLS_FLAGS_SKIP_HW flag.
Unlike U32 and flower cls_bpf already has some netlink
flags defined. I chose to create a new attribute to be
able to use the same flag values as the above.
Unknown flags are ignored and not reported upon dump.

Hi!
This is an updated version of BPF offload set.
Biggest change from the previous version is reusing the verifier
to check the exit codes and pointer types. The change to the
verifier is not very invasive and my gut feeling is that adding
simple hooks to the core verifier is cleaner than reimp

Add missing ABI defines and eBPF instructions to allow
mark to be passed on and extend prepend parsing on the
RX path to pick it up from packet metadata.

Add hardware bpf offload on our smart NICs. Detect if
capable firmware is loaded and use it to load the code JITed
with just added translator onto programmable engines.
This commit only supports offloading cls_bpf in legacy mode
