Merge branch 'bpf-x86-allow-function-arguments-up-to-12-for-tracing'

Menglong Dong says:

====================
bpf, x86: allow function arguments up to 12 for TRACING

From: Menglong Dong <imagedong

Merge branch 'bpf-x86-allow-function-arguments-up-to-12-for-tracing'

Menglong Dong says:

====================
bpf, x86: allow function arguments up to 12 for TRACING

From: Menglong Dong <imagedong@tencent.com>

For now, the BPF program of type BPF_PROG_TYPE_TRACING can only be used
on the kernel functions whose arguments count less than or equal to 6, if
not considering '> 8 bytes' struct argument. This is not friendly at all,
as too many functions have arguments count more than 6. According to the
current kernel version, below is a statistics of the function arguments
count:

argument count | function count
7 | 704
8 | 270
9 | 84
10 | 47
11 | 47
12 | 27
13 | 22
14 | 5
15 | 0
16 | 1

Therefore, let's enhance it by increasing the function arguments count
allowed in arch_prepare_bpf_trampoline(), for now, only x86_64.

In the 1st patch, we save/restore regs with BPF_DW size to make the code
in save_regs()/restore_regs() simpler.

In the 2nd patch, we make arch_prepare_bpf_trampoline() support to copy
function arguments in stack for x86 arch. Therefore, the maximum
arguments can be up to MAX_BPF_FUNC_ARGS for FENTRY, FEXIT and
MODIFY_RETURN. Meanwhile, we clean the potential garbage value when we
copy the arguments on-stack.

And the 3rd patch is for the testcases of the this series.

Changes since v9:
- fix the failed test cases of trampoline_count and get_func_args_test
in the 3rd patch

Changes since v8:
- change the way to test fmod_ret in the 3rd patch

Changes since v7:
- split the testcases, and add fentry_many_args/fexit_many_args to
DENYLIST.aarch64 in 3rd patch

Changes since v6:
- somit nits from commit message and comment in the 1st patch
- remove the inline in get_nr_regs() in the 1st patch
- rename some function and various in the 1st patch

Changes since v5:
- adjust the commit log of the 1st patch, avoiding confusing people that
bugs exist in current code
- introduce get_nr_regs() to get the space that used to pass args on
stack correct in the 2nd patch
- add testcases to tracing_struct.c instead of fentry_test.c and
fexit_test.c

Changes since v4:
- consider the case of the struct in arguments can't be hold by regs
- add comment for some code
- add testcases for MODIFY_RETURN
- rebase to the latest

Changes since v3:
- try make the stack pointer 16-byte aligned. Not sure if I'm right :)
- introduce clean_garbage() to clean the grabage when argument count is 7
- use different data type in bpf_testmod_fentry_test{7,12}
- add testcase for grabage values in ctx

Changes since v2:
- keep MAX_BPF_FUNC_ARGS still
- clean garbage value in upper bytes in the 2nd patch
- move bpf_fentry_test{7,12} to bpf_testmod.c and rename them to
bpf_testmod_fentry_test{7,12} meanwhile in the 3rd patch

Changes since v1:
- change the maximun function arguments to 14 from 12
- add testcases (Jiri Olsa)
- instead EMIT4 with EMIT3_off32 for "lea" to prevent overflow

Add fentry_many_args.c and fexit_many_args.c to test the fentry/fexit
with 7/11 arguments. As this feature is not supported by arm64 yet, we
disable these testcases for arm64 in DENYLIST.aarch64. We can combine
them with fentry_test.c/fexit_test.c when arm64 is supported too.

Correspondingly, add bpf_testmod_fentry_test7() and
bpf_testmod_fentry_test11() to bpf_testmod.c

Meanwhile, add bpf_modify_return_test2() to test_run.c to test the

Merge tag 'net-next-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"The sprinkling of SPI drivers is because we added a new one and Mark
sent us a SPI driver interface conversion pull request.

Core
----

- Introduce XDP multi-buffer support, allowing the use of XDP with
jumbo frame MTUs and combination with Rx coalescing offloads (LRO).

- Speed up netns dismantling (5x) and lower the memory cost a little.
Remove unnecessary per-netns sockets. Scope some lists to a netns.
Cut down RCU syncing. Use batch methods. Allow netdev registration
to complete out of order.

- Support distinguishing timestamp types (ingress vs egress) and
maintaining them across packet scrubbing points (e.g. redirect).

- Continue the work of annotating packet drop reasons throughout the
stack.

- Switch netdev error counters from an atomic to dynamically
allocated per-CPU counters.

- Rework a few preempt_disable(), local_irq_save() and busy waiting
sections problematic on PREEMPT_RT.

- Extend the ref_tracker to allow catching use-after-free bugs.

BPF
---

- Introduce "packing allocator" for BPF JIT images. JITed code is
marked read only, and used to be allocated at page granularity.
Custom allocator allows for more efficient memory use, lower iTLB
pressure and prevents identity mapping huge pages from getting
split.

- Make use of BTF type annotations (e.g. __user, __percpu) to enforce
the correct probe read access method, add appropriate helpers.

- Convert the BPF preload to use light skeleton and drop the
user-mode-driver dependency.

- Allow XDP BPF_PROG_RUN test infra to send real packets, enabling
its use as a packet generator.

- Allow local storage memory to be allocated with GFP_KERNEL if
called from a hook allowed to sleep.

- Introduce fprobe (multi kprobe) to speed up mass attachment (arch
bits to come later).

- Add unstable conntrack lookup helpers for BPF by using the BPF
kfunc infra.

- Allow cgroup BPF progs to return custom errors to user space.

- Add support for AF_UNIX iterator batching.

- Allow iterator programs to use sleepable helpers.

- Support JIT of add, and, or, xor and xchg atomic ops on arm64.

- Add BTFGen support to bpftool which allows to use CO-RE in kernels
without BTF info.

- Large number of libbpf API improvements, cleanups and deprecations.

Protocols
---------

- Micro-optimize UDPv6 Tx, gaining up to 5% in test on dummy netdev.

- Adjust TSO packet sizes based on min_rtt, allowing very low latency
links (data centers) to always send full-sized TSO super-frames.

- Make IPv6 flow label changes (AKA hash rethink) more configurable,
via sysctl and setsockopt. Distinguish between server and client
behavior.

- VxLAN support to "collect metadata" devices to terminate only
configured VNIs. This is similar to VLAN filtering in the bridge.

- Support inserting IPv6 IOAM information to a fraction of frames.

- Add protocol attribute to IP addresses to allow identifying where
given address comes from (kernel-generated, DHCP etc.)

- Support setting socket and IPv6 options via cmsg on ping6 sockets.

- Reject mis-use of ECN bits in IP headers as part of DSCP/TOS.
Define dscp_t and stop taking ECN bits into account in fib-rules.

- Add support for locked bridge ports (for 802.1X).

- tun: support NAPI for packets received from batched XDP buffs,
doubling the performance in some scenarios.

- IPv6 extension header handling in Open vSwitch.

- Support IPv6 control message load balancing in bonding, prevent
neighbor solicitation and advertisement from using the wrong port.
Support NS/NA monitor selection similar to existing ARP monitor.

- SMC
- improve performance with TCP_CORK and sendfile()
- support auto-corking
- support TCP_NODELAY

- MCTP (Management Component Transport Protocol)
- add user space tag control interface
- I2C binding driver (as specified by DMTF DSP0237)

- Multi-BSSID beacon handling in AP mode for WiFi.

- Bluetooth:
- handle MSFT Monitor Device Event
- add MGMT Adv Monitor Device Found/Lost events

- Multi-Path TCP:
- add support for the SO_SNDTIMEO socket option
- lots of selftest cleanups and improvements

- Increase the max PDU size in CAN ISOTP to 64 kB.

Driver API
----------

- Add HW counters for SW netdevs, a mechanism for devices which
offload packet forwarding to report packet statistics back to
software interfaces such as tunnels.

- Select the default NIC queue count as a fraction of number of
physical CPU cores, instead of hard-coding to 8.

- Expose devlink instance locks to drivers. Allow device layer of
drivers to use that lock directly instead of creating their own
which always runs into ordering issues in devlink callbacks.

- Add header/data split indication to guide user space enabling of
TCP zero-copy Rx.

- Allow configuring completion queue event size.

- Refactor page_pool to enable fragmenting after allocation.

- Add allocation and page reuse statistics to page_pool.

- Improve Multiple Spanning Trees support in the bridge to allow
reuse of topologies across VLANs, saving HW resources in switches.

- DSA (Distributed Switch Architecture):
- replay and offload of host VLAN entries
- offload of static and local FDB entries on LAG interfaces
- FDB isolation and unicast filtering

Daniel Borkmann says:

====================
pull-request: bpf-next 2022-02-09

We've added 126 non-merge commits during the last 16 day(s) which contain
a total of 201 files changed, 4049 insertions(+), 2215 deletions(-).

The main changes are:

1) Add custom BPF allocator for JITs that pack multiple programs into a huge
page to reduce iTLB pressure, from Song Liu.

2) Add __user tagging support in vmlinux BTF and utilize it from BPF
verifier when generating loads, from Yonghong Song.

3) Add per-socket fast path check guarding from cgroup/BPF overhead when
used by only some sockets, from Pavel Begunkov.

4) Continued libbpf deprecation work of APIs/features and removal of their
usage from samples, selftests, libbpf & bpftool, from Andrii Nakryiko
and various others.

5) Improve BPF instruction set documentation by adding byte swap
instructions and cleaning up load/store section, from Christoph Hellwig.

6) Switch BPF preload infra to light skeleton and remove libbpf dependency
from it, from Alexei Starovoitov.

7) Fix architecture-agnostic macros in libbpf for accessing syscall
arguments from BPF progs for non-x86 architectures,
from Ilya Leoshkevich.

8) Rework port members in struct bpf_sk_lookup and struct bpf_sock to be
of 16-bit field with anonymous zero padding, from Jakub Sitnicki.

9) Add new bpf_copy_from_user_task() helper to read memory from a different
task than current. Add ability to create sleepable BPF iterator progs,
from Kenny Yu.

10) Implement XSK batching for ice's zero-copy driver used by AF_XDP and
utilize TX batching API from XSK buffer pool, from Maciej Fijalkowski.

11) Generate temporary netns names for BPF selftests to avoid naming
collisions, from Hangbin Liu.

12) Implement bpf_core_types_are_compat() with limited recursion for
in-kernel usage, from Matteo Croce.

13) Simplify pahole version detection and finally enable CONFIG_DEBUG_INFO_DWARF5
to be selected with CONFIG_DEBUG_INFO_BTF, from Nathan Chancellor.

14) Misc minor fixes to libbpf and selftests from various folks.

Merge branch 'migrate from bpf_prog_test_run{,_xattr}'

Delyan Kratunov says:

====================

Fairly straight-forward mechanical transformation from bpf_prog_test_run
and bpf_prog_test_run_xat

Merge branch 'migrate from bpf_prog_test_run{,_xattr}'

Delyan Kratunov says:

====================

Fairly straight-forward mechanical transformation from bpf_prog_test_run
and bpf_prog_test_run_xattr to the bpf_prog_test_run_opts goodness.

I did a fair amount of drive-by CHECK/CHECK_ATTR cleanups as well, though
certainly not everything possible. Primarily, I did not want to just change
arguments to CHECK calls, though I had to do a bit more than that
in some cases (overall, -119 CHECK calls and all CHECK_ATTR calls).

v2 -> v3:
Don't introduce CHECK_OPTS, replace CHECK/CHECK_ATTR usages we need to touch
with ASSERT_* calls instead.
Don't be prescriptive about the opts var name and keep old names where that would
minimize unnecessary code churn.
Drop _xattr-specific checks in prog_run_xattr and rename accordingly.

v1 -> v2:
Split selftests/bpf changes into two commits to appease the mailing list.

selftests/bpf: Migrate from bpf_prog_test_run

bpf_prog_test_run is being deprecated in favor of the OPTS-based
bpf_prog_test_run_opts.
We end up unable to use CHECK in most cases, so replace usages
