In verifier function adjust_scalar_min_max_vals,
when src_known is false and the opcode is BPF_LSH/BPF_RSH,
early return will happen in the function. So remove
the branch in handling BPF_LSH/BPF_RSH when src_known is false.

There is no functionality change in this patch. The common-purpose
trace functions, including perf_event polling and ksym lookup,
are moved from trace_output_user.c and bpf_load.c to
selftests/bpf/trace_helpers.c so that these function can
be reused later in selftests.

When helpers like bpf_get_stack returns an int value
and later on used for arithmetic computation, the LSH and ARSH
operations are often required to get proper sign extension into
64-bit. For example, without this patch:
54: R0=inv(id=0,umax_value=800)
54: (bf) r8 = r0
55: R0=inv(id=0,u
Currently, stackmap and bpf_get_stackid helper are provided
for bpf program to get the stack trace. This approach has
a limitation though. If two stack traces have the same hash,
only one will get stored in the stackmap table,
so some stack traces are missing from user perspective.
This patch impl
The test_verifier already has a few ARSH test cases.
This patch adds a new test case which takes advantage of newly
improved verifier behavior for bpf_get_stack and ARSH.

We used to return descriptor head by vhost_get_vq_desc() to device and

internal used ring layout to device which makes it hard to be extended for

We assumes used ring update is the only user for vhost_put_user() in

Hi all:
This RFC implement packed ring layout. The code were tested with
Tiwei's RFC V2 a thttps://lkml.org/lkml/2018/4/1/48. Some fixups and
tweaks were needed on top of Tiwei's code to make it run. TCP stream
and pktgen does not show obvious difference compared with split ring.
Changes from V2:
Move get_rx_bufs() to vhost.c and rename it to
vhost_get_rx_bufs(). This helps to hide vring internal layout from
specific device implementation. Packed ring implementation will
benefit from this.

In TLS inline crypto, we can have one direction in software
and another in hardware. Thus, we split the TLS configuration to separate
structures for receive and transmit.

With socket dependent offloads we rely on the netdev to transform
the transmitted packets before sending them to the wire.
When a packet from an offloaded socket is rerouted to a different
device we need to detect it and do the transformation in software.

Hi Dave,
The following series provides TLS TX inline crypto offload.
v1->v2:
- Added IS_ENABLED(CONFIG_TLS_DEVICE) and a STATIC_KEY for icsk_clean_acked
- File license fix
- Fix spelling, comment by DaveW
- Move memory allocations out of tls_set_device_offload and other misc fixes,

There's no benefit in using netif_info et al before the net_device has
been registered. We get messages like
r8169 :03:00.0 (unnamed net_device) (uninitialized): [message]
Therefore use dev_info/dev_err instead.
As a side effect we don't need parameter dev for function

With sk_cookie we can identify a socket, that is very helpful for
traceing and statistic, i.e. tcp tracepiont and ebpf.
So we'd better init it by default for inet socket.
When using it, we just need call atomic64_read(&sk->sk_cookie).
