skbuff: Switch structure bounds to struct_group()
This is a pair of patches to add struct_group() to struct sk_buff. The
first is needed to work around sparse-specific complaints, and is new

In preparation for FORTIFY_SOURCE performing compile-time and run-time
field bounds checking for memcpy(), memmove(), and memset(), avoid
intentionally writing across neighboring fields.
Replace the existing empty member position markers "headers_start" and
"headers_end" with a struct_group(). This will allow memcpy() and sizeof()
to more easily reason about sizes, and improve readability.
"pahole" shows no size nor member offset changes to struct sk_buff.
"objdump -d" shows no object code changes (outside of WARNs affected by
source line number changes).

In preparation for using the struct_group() macro in struct sk_buff,
move the conditional preprocessor directives out of the region of struct
sk_buff that will be enclosed by struct_group(). While GCC and Clang are
happy with conditional preprocessor directives here, sparse is not, even
under -Wno-directive-within-macro[1], as would be seen under a C=1 build:
net/core/filter.c: note: in included file (through include/linux/netlink.h, include/linux/sock_diag.h):
./include/linux/skbuff.h:820:1: warning: directive in macro's argument list

./include/linux/skbuff.h:848:1: warning: directive in macro's argument list
Additionally remove empty macro argument definitions and usage.
"objdump -d" shows no object code differences.

When checking an address is located in a global data section also check
for the .bss section as global variables initialized to 0 can be in
there (-fzero-initialized-in-bss).
This was found when looking at ensure_safe_net_sysctl which was failing
to detect non-init sysctl pointing to a global data section when the

This patch brings in support for device trace collection.
It implements relayfs interface for pushing device trace
from kernel space to user space.
Driver gets the debugfs base directory associated to WWAN
Device and creates trace_control and trace debugfs for
device tracing. Both trace_control & trace debugfs are
created under /sys/kernel/debug/wwan/wwan0/.
In order to collect device trace on trace0 interface, user
need to write 1 to trace_ctl interface.

This patch set brings in a common debugfs base directory
i.e. /sys/kernel/debugfs/wwan/ in WWAN Subsystem for a
WWAN device instance. So that it avoids driver polluting
debugfs root with unrelated directories & possible name
collusion.
Having a common debugfs base directory for WWAN drivers
eases user to match control devices with debugfs entries.
WWAN Subsystem creates dentry (/sys/kernel/debugfs/wwan)
on module load & removes dentry on module unload.
When driver registers a new wwan device, dentry (wwanX)
is created for WWAN device instance & on driver unregister
dentry is removed.
New API is introduced to return the wwan device instance
dentry so that driver can create debugfs entries under it.

Some devices expose memory-mapped c22-compliant PHYs. Because these
devices do not have an MDIO bus, we cannot use the existing helpers.
Refactor the existing helpers to allow supplying the values for c22
registers directly, instead of using MDIO to access them. Only get_state
and set_advertisement are converted, since they contain the most complex
logic. Because set_advertisement is never actually used outside
phylink_mii_c22_pcs_config, move the MDIO-writing part into that
function. Because some modes do not need the advertisement register set
at all, we use -EINVAL for this purpose.
Additionally, a new function phylink_pcs_enable_an is provided to
determine whether to enable autonegotiation.

ethtool: add support to set/get tx copybreak buf size and rx buf len
This series add support to set/get tx copybreak buf size and rx buf len via
ethtool and hns3 driver implements them.
Tx copybreak buf size is used for tx copybreak feature which for small size
packet or frag. Use ethtool --get-tunable command to get it, and ethtool
--set-tunable command to set it, examples are as follow:
1. set tx spare buf size to 102400:
$ ethtool --set-tunable eth1 tx-buf-size 102400
2. get tx spare buf size:
$ ethtool --get-tunable eth1 tx-buf-size
tx-buf-size: 102400
Rx buf len is buffer length of each rx BD. Use ethtool -g command to get
it, and ethtool -G command to set it, examples are as follow:
1. set rx buf len to 4096
$ ethtool -G eth1 rx-buf-len 4096
2. get rx buf len
$ ethtool -g eth1
...
RX Buf Len: 4096
Change log:
V5 -> V6
1.Fix compile error for divers/s390.
V4 -> V5
1.Change struct ethtool_ringparam_ext to kernel_ethtool_ringparam.
2.change "__u32 rx_buf_len" to "u32 rx_buf_len".
V3 -> V4
1.Fix a few allmodconfig compile warning.
2.Add more '=' synbol to ethtool-netlink.rst to refine format.
3.Move definement of struct ethtool_ringparam_ext to include/linux/ethtool.h.
4.Move related modify of rings_fill_reply() from patch 4/6 to patch 3/6.
V2 -> V3
1.Remove documentation for tx copybreak buf size, there is description for
it in userspace ethtool.
2.Move extending parameters for get/set_ringparam function from patch3/6
to patch 4/6.
V1 -> V2
1.Add documentation for rx buf len and tx copybreak buf size.
2.Extend structure ringparam_ext for extenal ring params.
3.Change type of ETHTOOL_A_RINGS_RX_BUF_LEN from NLA_U32 to
NLA_POLICY_MIN(NLA_U32, 1).

SOL_IP provides a way to configure network layer attributes in a
socket. This patch adds support for IP_TOS for setsockopt(.. ,SOL_IP, ..)
Support for SOL_IP is added in mptcp_setsockopt() and IP_TOS is handled in
a private function. The idea here is to take in the value passed for IP_TOS
and set it to the current subflow, open subflows as well new subflows that
might be created after the initial call to setsockopt(). This sync is done
using sync_socket_options(.., ssk) and setting the value of tos using
__ip_sock_set_tos(ssk,..).
The patch has been tested using the packetdrill script here -
