Rather than pass in flags, error pointer, and whether this is a kernel
invocation or not, add a struct proto_accept_arg struct as the argument.
This then holds all of these arguments, and prepares accept for being
able to pass back more information.
No functional changes in this patch.

====================
Intel Wired LAN Driver Updates 2024-05-08 (most Intel drivers)
This series contains updates to i40e, iavf, ice, igb, igc, e1000e, and ixgbe
drivers.
Asbjørn Sloth Tønnesen adds checks against supported flower control flags
for i40e, iavf, ice, and igb drivers.
Michal corrects filters removed during eswitch release for ice.
Corinna Vinschen defers PTP initialization to later in probe so that
netdev log entry is initialized on igc.
Ilpo Järvinen removes a couple of unused, duplicate defines on
e1000e and ixgbe.
* '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
net: e1000e & ixgbe: Remove PCI_HEADER_TYPE_MFD duplicates
igc: fix a log entry using uninitialized netdev
ice: remove correct filters during eswitch release

PCI_HEADER_TYPE_MULTIFUNC is define by e1000e and ixgbe and both are
unused. There is already PCI_HEADER_TYPE_MFD in pci_regs.h anyway which
should be used instead so remove the duplicated defines of it.

During successful probe, igc logs this:
[ 5.133667] igc 0000:01:00.0 (unnamed net_device) (uninitialized): PHC added
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The reason is that igc_ptp_init() is called very early, even before
register_netdev() has been called. So the netdev_info() call works
on a partially uninitialized netdev.
Fix this by calling igc_ptp_init() after register_netdev(), right
after the media autosense check, just as in igb. Add a comment,
just as in igb.
Now the log message is fine:
[ 5.200987] igc 0000:01:00.0 eth0: PHC added

ice_clear_dflt_vsi() is only removing default rule. Both default RX and
TX rule should be removed during release.
If it isn't switching to switchdev, second time results in error, because
TX filter is already there.
Fix it by removing the correct set of rules.
Fixes: 50d62022f455 ("ice: default Tx rule instead of to queue")

Use flow_rule_match_has_control_flags() to check for control flags,
such as can be set through `tc flower ... ip_flags frag`.
In case any control flags are masked, flow_rule_match_has_control_flags()
sets a NL extended error message, and we return -EOPNOTSUPP.

====================
net: qede: convert filter code to use extack
This series converts the filter code in the qede driver
to use NL_SET_ERR_MSG_*(extack, ...) for error handling.
Patch 1-12 converts qede_parse_flow_attr() to use extack,
along with all it's static helper functions.
qede_parse_flow_attr() is used in two places:
- qede_add_tc_flower_fltr()
- qede_flow_spec_to_rule()
In the latter call site extack is faked in the same way as
is done in mlxsw (patch 12).
While the conversion is going on, some error messages are silenced
in between patch 1-12. If wanted could squash patch 1-12 in a v3, but
I felt that it would be easier to review as 12 more trivial patches.
Patch 13 and 14, finishes up by converting qede_parse_actions(),
and ensures that extack is propagated to it, in both call contexts.

Since qede_parse_flow_attr() now does error reporting
through extack, then give it a fake extack and extract the
error message afterwards if one was set.
The extracted error message is then passed on through
DP_NOTICE(), including messages that was earlier issued
with DP_INFO().
This fake extack approach is already used by
mlxsw_env_linecard_modules_power_mode_apply() in
drivers/net/ethernet/mellanox/mlxsw/core_env.c

Convert qede_flow_parse_ports to use extack,
and drop the edev argument.
Convert DP_NOTICE call to use NL_SET_ERR_MSG_MOD instead.
In calls to qede_flow_parse_ports(), use NULL as extack
for now, until a subsequent patch makes extack available.

Some usb drivers try to set small skb->truesize and break
core networking stacks.
In this patch, I removed one of the skb->truesize override.
I also replaced one skb_clone() by an allocation of a fresh
and small skb, to get minimally sized skbs, like we did
in commit 1e2c61172342 ("net: cdc_ncm: reduce skb truesize
in rx path") and 4ce62d5b2f7a ("net: usb: ax88179_178a:
stop lying about skb->truesize")
v3: also fix a sparse error ( https://lore.kernel.org/oe-kbuild-all/202405091310.KvncIecx-lkp@intel.com/ )
v2: leave the skb_trim() game because smsc95xx_rx_csum_offload()
needs the csum part. (Jakub)
While we are it, use get_unaligned() in smsc95xx_rx_csum_offload().

Commit 1af2dface5d2 ("af_unix: Don't access successor in unix_del_edges()
during GC.") fixed use-after-free by avoid accessing edge->successor while
GC is in progress.
However, there could be a small race window where another process could
call unix_del_edges() while gc_in_progress is true and __skb_queue_purge()
is on the way.
So, we need another marker for struct scm_fp_list which indicates if the
skb is garbage-collected.
This patch adds dead flag in struct scm_fp_list and set it true before
calling __skb_queue_purge().

Real number of Transmit queues are incremented when user enables HTB
class and vice versa. Depending on SKB priority driver returns transmit
queue (Txq). Transmit queues and Send queues are one-to-one mapped.
In few scenarios, Driver is returning transmit queue value which is
greater than real number of transmit queue and Stack detects this as
error and overwrites transmit queue value.
For example
user has added two classes and real number of queues are incremented
accordingly
- tc class add dev eth1 parent 1: classid 1:1 htb
rate 100Mbit ceil 100Mbit prio 1 quantum 1024
- tc class add dev eth1 parent 1: classid 1:2 htb
rate 100Mbit ceil 200Mbit prio 7 quantum 1024
now if user deletes the class with id 1:1, driver decrements the real
number of queues
- tc class del dev eth1 classid 1:1
But for the class with id 1:2, driver is returning transmit queue
value which is higher than real number of transmit queue leading
to below error
eth1 selects TX queue x, but real number of TX queues is x
This patch solves the problem by assigning deleted class transmit
queue/send queue to active class.

On slow machines the SND timestamp sometimes doesn't arrive before
we quit. The test only waits as long as the packet delay, so it's
easy for a race condition to happen.
Double the wait but do a bit of polling, once the SND timestamp
arrives there's no point to wait any longer.

gtp pull request 24-05-07
This v3 includes:
- fix for clang uninitialized variable per Jakub.
- address Smatch and Coccinelle reports per Simon
- remove inline in new IPv6 support per Simon
- fix memleaks in netlink control plane per Simon
-o-
The following patchset contains IPv6 GTP driver support for net-next,
this also includes IPv6 over IPv4 and vice-versa:
Patch #1 removes a unnecessary stack variable initialization in the
socket routine.
Patch #2 deals with GTP extension headers. This variable length extension
header to decapsulate packets accordingly. Otherwise, packets are
dropped when these extension headers are present which breaks
interoperation with other non-Linux based GTP implementations.
Patch #3 prepares for IPv6 support by moving IPv4 specific fields in PDP
context objects to a union.
Patch #4 adds IPv6 support while retaining backward compatibility.
Three new attributes allows to declare an IPv6 GTP tunnel
GTPA_FAMILY, GTPA_PEER_ADDR6 and GTPA_MS_ADDR6 as well as
IFLA_GTP_LOCAL6 to declare the IPv6 GTP UDP socket. Up to this
patch, only IPv6 outer in IPv6 inner is supported.
Patch #5 uses IPv6 address /64 prefix for UE/MS in the inner headers.
Unlike IPv4, which provides a 1:1 mapping between UE/MS,
IPv6 tunnel encapsulates traffic for /64 address as specified
by 3GPP TS. Patch has been split from Patch #4 to highlight
this behaviour.
Patch #6 passes up IPv6 link-local traffic, such as IPv6 SLAAC, for
handling to userspace so they are handled as control packets.
Patch #7 prepares to allow for GTP IPv4 over IPv6 and vice-versa by
moving IP specific debugging out of the function to build
IPv4 and IPv6 GTP packets.
Patch #8 generalizes TOS/DSCP handling following similar approach as
in the existing iptunnel infrastructure.
Patch #9 adds a helper function to build an IPv4 GTP packet in the outer
header.
Patch #10 adds a helper function to build an IPv6 GTP packet in the outer
header.
Patch #11 adds support for GTP IPv4-over-IPv6 and vice-versa.
Patch #12 allows to use the same TID/TEID (tunnel identifier) for inner
IPv4 and IPv6 packets for better UE/MS dual stack integration.
This series integrates with the osmocom.org project CI and TTCN-3 test
infrastructure (Oliver Smith) as well as the userspace libgtpnl library.
Thanks to Harald Welte, Oliver Smith and Pau Espin for reviewing and
providing feedback through the osmocom.org redmine platform to make this
happen.

Add new protocol field to PDP context that determines the transmit path
IP protocol to encapsulate the original packets, either IPv4 or IPv6.
Relax existing netlink attribute checks to allow to specify different
family in MS and peer attributes from the control plane.
Use build helpers to tx path to encapsulate IPv4-in-IPv6-GTP and
IPv6-in-IPv4-GTP according to the user-specified configuration.
From rx path, snoop for the inner protocol header since outer
skb->protocol might differ and use this to validate for valid PDP
context and to restore skb->protocol after decapsulation.

Harald Welte reports that according to 3GPP TS 29.060:
PDN Connection: the association between a MS represented by one IPv4
address and/or one IPv6 prefix and a PDN represented by an APN.
this clearly states that IPv4 is a single address while IPv6 is a single prefix.
Then, 3GPP TS 29.061, Section 11.2.1.3:
For APNs that are configured for IPv6 address allocation, the GGSN/P-GW
shall only use the Prefix part of the IPv6 address for forwarding of mobile
terminated IP packets. The size of the prefix shall be according to the maximum
prefix length for a global IPv6 address as specified in the IPv6 Addressing
Architecture, see RFC 4291 [82].
RFC 4291 section 2.5.4 states
All Global Unicast addresses other than those that start with binary 000
have a 64-bit interface ID field (i.e., n + m = 64) ...
3GPP TS 29.61 Section 11.2.1.3.2a:
In the procedure in the cases of using GTP-based S5/S8, P-GW acts as an
access router, and allocates to a UE a globally unique /64 IPv6 prefix if the
PLMN allocates the prefix.
Therefore, compare IPv6 address /64 prefix only since MS/UE is not a single
address like in the IPv4 case.
Reject IPv6 address with EADDRNOTAVAIL if it lower 64 bits of the IPv6 address
from the control plane are set.

Add new iflink attributes to configure in-kernel UDP listener socket
address: IFLA_GTP_LOCAL and IFLA_GTP_LOCAL6. If none of these attributes
are specified, default is still to IPv4 INADDR_ANY for backward
compatibility.
Add new attributes to set up family and IPv6 address of GTP tunnels:
GTPA_FAMILY, GTPA_PEER_ADDR6 and GTPA_MS_ADDR6. If no GTPA_FAMILY is
specified, AF_INET is assumed for backward compatibility.
setsockopt IPV6_ADDRFORM allows to downgrade socket from IPv6 to IPv4
after socket is bound. Assumption is that socket listener that is
attached to the gtp device needs to be either IPv4 or IPv6. Therefore,
GTP socket listener does not allow for IPv4-mapped-IPv6 listener.

Currently GTP packets are dropped if the next extension field is set to
non-zero value, but this are valid GTP packets.
TS 29.281 provides a longer header format, which is defined as struct
gtp1_header_long. Such long header format is used if any of the S, PN, E
flags is set.
This long header is 4 bytes longer than struct gtp1_header, plus
variable length (optional) extension headers. The next extension header
field is zero is no extension header is provided.
The extension header is composed of a length field which includes total
number of 4 byte words including the extension header itself (1 byte),
payload (variable length) and next type (1 byte). The extension header
size and its payload is aligned to 4 bytes.
A GTP packet might come with a chain extensions headers, which makes it
slightly cumbersome to parse because the extension next header field
comes at the end of the extension header, and there is a need to check
if this field becomes zero to stop the extension header parser.

Update b20dc3c68458 ("gtp: Allow to create GTP device without FDs") to
remove useless initialization to NULL, sockets are initialized to
non-NULL just a few lines of code after this.
