In this patchset few bugs related to RSS are fixed and RSS table and
hash key configuration is added.
We also do increase max number of HW rings upto 8.

The bpf_xsk_redirect function is a new redirect bpf function, in

bpf_xsk_redirect is called, the packet will be redirected to the

Break up bpf_prog_load into one function that allocates, initializes

Hi!
This patch set adds support for a new XDP socket bind option,
XDP_ATTACH.
The rationale behind attach is performance and ease of use. Many XDP
socket users just need a simple way of creating/binding a socket and
receiving frames right away without loading an XDP program.
From: Björn Töpel
Prior this commit, when the struct socket object was being released,
the UMEM did not have its reference count decreased. Instead, this was
done in the struct sock sk_destruct function.
There is no reason to keep the UMEM reference around when the socket
is being orphaned, so
From: Björn Töpel
In this commit the XDP_ATTACH bind() flag is introduced. When an XDP
socket is bound with this flag set, the socket will be associated with
a certain netdev Rx queue. The idea is that the XDP socket users do
not have to deal with the XSKMAP, or even an XDP program. Instead

This commit extends the XDP_ATTACH bind option by loading a builtin

The builtin program is the simplest program possible to redirect a

The added bpf_prog_load_builtin can be used to load and verify a BPF

allows for the kernel to use the bpf infrastructure for internal
tasks.

Currently, the destination register is marked as unknown for 32-bit
sub-register move (BPF_MOV | BPF_ALU) whenever the source register type is
SCALAR_VALUE.
This is too conservative that some valid cases will be rejected.
Especially, this may turn a constant scalar value into unknown value that

I think it makes sense to allow a fixed phy carrier to be changed from
user space. However, i don't think you can easily plumb that to

I just sent it this Monday and the subject for that patch is

Add code to handle optional reset GPIO in the KSZ switch driver. The switch
has a reset GPIO line which can be controlled by the CPU, so make sure it is
configured correctly in such setups.

1) bpf_load_program_xattr() is absorbing the EBIG error
which makes testing this case impossible. It is replaced
with a direct syscall(__NR_bpf, BPF_PROG_LOAD,...).
2) The test_func_type() is renamed to test_info_raw() to
prepare for the new line_info test in the next patch.
3) The
This patch series introduces the bpf_line_info. Please see individual patch
for details.
It will be useful for introspection purpose, like:
[root@arch-fb-vm1 bpf]# ~/devshare/fb-kernel/linux/tools/bpf/bpftool/bpftool
prog dump jited pinned /sys/fs/bpf/test_btf_haskv
[...]
int
This patch adds print bpf_line_info function in 'prog dump jitted'
and 'prog dump xlated':
[root@arch-fb-vm1 bpf]# ~/devshare/fb-kernel/linux/tools/bpf/bpftool/bpftool
prog dump jited pinned /sys/fs/bpf/test_btf_haskv
[...]
int test_long_fname_2(struct dummy_tracepoint_args * arg):
Add unit tests for bpf_line_info for both BPF_PROG_LOAD and
BPF_OBJ_GET_INFO_BY_FD.
jit enabled:
[root@arch-fb-vm1 bpf]# ./test_btf -k 0
BTF prog info raw test[5] (line_info (No subprog)): OK
BTF prog info raw test[6] (line_info (No subprog. insn_off >= prog->len)): OK
BTF prog info raw test[7]
This patch refactor and fix a bug in the libbpf's bpf_func_info loading
logic. The bug fix and refactoring are targeting the same
commit 2993e0515bb4 ("tools/bpf: add support to read .BTF.ext sections")
which is in the bpf-next branch.
1) In bpf_load_program_xattr(), it should retry when errno

Interesting... this patch was on top of net-next/master, and it still
rebases cleanly on current net-next/master.
Would you like it on net/master instead? It indeed

Similar to routes and rules, add protocol attribute to neighbor entries

Add optional reset GPIO, as such a signal is available on the KSZ switches.
