tun/tap: use kfree_skb_reason() to trace dropped skb
The commit c504e5c2f9 ("net: skb: introduce kfree_skb_reason()") has
introduced the kfree_skb_reason() to help track the reason.
The tun and tap are commonly used as virtio-net/vhost-net backend. This is to
use kfree_skb_reason() to trace the dropped skb for those two drivers.
Changed since v1:
- I have renamed many of the reasons since v1. I make them as generic as
possible so that they can be re-used by core networking and drivers.
Changed since v2:
- declare drop_reason as type "enum skb_drop_reason"
- handle the drop in skb_list_walk_safe() case for tap driver, and
kfree_skb_list_reason() is introduced
Changed since v3 (only for PATCH 4/4):
- rename to TAP_FILTER and TAP_TXFILTER
- honor reverse xmas tree style declaration for 'drop_reason' in
tun_net_xmit()
Changed since v4:
- make kfree_skb_list() static inline
- add 'computation' to SKB_CSUM comment
- change COPY_DATA to UCOPY_FAULT
- add 'metadata' to DEV_HDR comment
- expand comment on DEV_READY
- change SKB_TRIM to NOMEM
- chnage SKB_PULL to HDR_TRUNC
Changed since v5:
- rebase to net-next
The following reasons are introduced.
- SKB_DROP_REASON_SKB_CSUM
- SKB_DROP_REASON_SKB_GSO_SEG
- SKB_DROP_REASON_SKB_UCOPY_FAULT
- SKB_DROP_REASON_DEV_HDR
- SKB_DROP_REASON_FULL_RING
- SKB_DROP_REASON_DEV_READY
- SKB_DROP_REASON_NOMEM
- SKB_DROP_REASON_HDR_TRUNC
- SKB_DROP_REASON_TAP_FILTER
- SKB_DROP_REASON_TAP_TXFILTER
This is the output for TUN device.

The TUN can be used as vhost-net backend. E.g, the tun_net_xmit() is the
interface to forward the skb from TUN to vhost-net/virtio-net.
However, there are many "goto drop" in the TUN driver. Therefore, the
kfree_skb_reason() is involved at each "goto drop" to help userspace
ftrace/ebpf to track the reason for the loss of packets.
The below reasons are introduced:
- SKB_DROP_REASON_DEV_READY
- SKB_DROP_REASON_NOMEM
- SKB_DROP_REASON_HDR_TRUNC
- SKB_DROP_REASON_TAP_FILTER
- SKB_DROP_REASON_TAP_TXFILTER

If the flow control settings have been changed, a subsequent FW reset
may cause the ethernet link to toggle unnecessarily. This link toggle
will increase the down time by a few seconds.
The problem is caused by bnxt_update_phy_setting() detecting a false
mismatch in the flow control settings between the stored software
settings and the current FW settings after the FW reset. This mismatch
is caused by the AUTONEG bit added to link_info->req_flow_ctrl in an
inconsistent way in bnxt_set_pauseparam() in autoneg mode. The AUTONEG
bit should not be added to link_info->req_flow_ctrl.

If a memory allocation error occurred during an attempt to refill a slot
in the RX ring after the packet was received, the hardware tail pointer
would still have been updated to point to or past the slot which remained
marked as previously completed. This would likely result in the DMA engine
raising an error when it eventually tried to use that slot again.
If a slot cannot be refilled, then just stop processing and do not move
the tail pointer past it. On the next attempt, we should skip receiving
the packet from the empty slot and just try to refill it again.
This failure mode has not actually been observed, but was found as part
of other driver updates.

net: dsa: realtek: add rtl8_4t tag
This patch series adds support for rtl8_4t tag. It is a variant of
rtl8_4 tag, with identical values but placed at the end of the packet
(before CRC).
It forces checksum in software before adding the tag as those extra
bytes at the end of the packet would be summed together with the rest of
the payload. When the switch removes the tag before sending the packet
to the network, that checksum will not match.
It might be useful to diagnose or avoid checksum offload issues. With an
ethertype tag like rtl8_4, the cpu port ethernet driver must work with
cksum_start and chksum_offset to correctly calculate checksums. If not,
the checksum field will be broken (it will contain the fake ip header
sum). In those cases, using 'rtl8_4t' might be an alternative way to
avoid checksum offload, either using runtime or device-tree property.
Regards,
Luiz
v4-v5)
- tags in alphabetical order in dsa_port.yaml
- remove ret var from rtl8365mb_change_tag_protocol
- Comment typos fixes
v3-v4)
- added rtl8_4 and rtl8_4t to dsa_port.yaml
- removed generic considerations about checksum problems with DSA tags.
They belong to Documentation/networking/dsa/dsa.rst
v2-v3)

- do not remove position and format from rtl8365mb_cpu
- reinstate cpu to rtl8365mb
- moved rtl8365mb_change_tag_protocol after rtl8365mb_cpu_config
- do not modify rtl8365mb_cpu_config() logic
- remove cpu arg from rtl8365mb_cpu_config(); get it from priv
- dropped tag_protocol from rtl8365mb. It is now derived from
cpu->position.
- init cpu struct before dsa_register as default tag must be already
defined before dsa_register()
- fix formatting issues
v1-v2)
- remove mention to tail tagger, use trailing tagger.
- use void* instead of char* for pointing to tag beginning
- use memcpy to avoid problems with unaligned tags

pull-request: bpf-next 2022-03-04
We've added 32 non-merge commits during the last 14 day(s) which contain
a total of 59 files changed, 1038 insertions(+), 473 deletions(-).
The main changes are:
1) Optimize BPF stackmap's build_id retrieval by caching last valid build_id,
as consecutive stack frames are likely to be in the same VMA and therefore
have the same build id, from Hao Luo.
2) Several improvements to arm64 BPF JIT, that is, support for JITing
the atomic[64]_fetch_add, atomic[64]_[fetch_]{and,or,xor} and lastly
atomic[64]_{xchg|cmpxchg}. Also fix the BTF line info dump for JITed
programs, from Hou Tao.
3) Optimize generic BPF map batch deletion by only enforcing synchronize_rcu()
barrier once upon return to user space, from Eric Dumazet.
4) For kernel build parse DWARF and generate BTF through pahole with enabled
multithreading, from Kui-Feng Lee.
5) BPF verifier usability improvements by making log info more concise and
replacing inv with scalar type name, from Mykola Lysenko.
6) Two follow-up fixes for BPF prog JIT pack allocator, from Song Liu.
7) Add a new Kconfig to allow for loading kernel modules with non-matching
BTF type info; their BTF info is then removed on load, from Connor O'Brien.
8) Remove reallocarray() usage from bpftool and switch to libbpf_reallocarray()
in order to fix compilation errors for older glibc, from Mauricio Vásquez.
9) Fix libbpf to error on conflicting name in BTF when type declaration
appears before the definition, from Xu Kuohai.
10) Fix issue in BPF preload for in-kernel light skeleton where loaded BPF
program fds prevent init process from setting up fd 0-2, from Yucong Sun.
11) Fix libbpf reuse of pinned perf RB map when max_entries is auto-determined
by libbpf, from Stijn Tintel.
12) Several cleanups for libbpf and a fix to enforce perf RB map #pages to be
non-zero, from Yuntao Wang.

The field adv_instance_cnt is always accessed within a device lock,
except in the function add_advertising. A concurrent remove of an
advertisement with adding another one could result in the if check
"if a new instance was actually added" to not trigger, resulting
in not triggering the "advertising added event".
