There's quite a bit of code accessing sband iftype data
(HE, HE 6 GHz, EHT) and we always need to remember to use
the ieee80211_vif_type_p2p() helper. Add new helpers to
directly get it from the sband/vif rather than having to
call ieee80211_vif_type_p2p().
Convert most code with the following spatch:

wireless-next patches for v6.5
The second pull request for v6.5. We have support for three new
Realtek chipsets, all from different generations. Shows how active
Realtek development is right now, even older generations are being
worked on.
Note: We merged wireless into wireless-next to avoid complex conflicts
between the trees.
Major changes:
rtl8xxxu
- RTL8192FU support
rtw89
- RTL8851BE support
rtw88
- RTL8723DS support
ath11k
- Multiple Basic Service Set Identifier (MBSSID) and Enhanced MBSSID
Advertisement (EMA) support in AP mode
iwlwifi
- support for segmented PNVM images and power tables
- new vendor entries for PPAG (platform antenna gain) feature
cfg80211/mac80211
- more Multi-Link Operation (MLO) support such as hardware restart
- fixes for a potential work/mutex deadlock and with it beginnings of
the previously discussed locking simplifications

Replace generic_splice_sendpage() + splice_from_pipe + pipe_to_sendpage()
with a net-specific handler, splice_to_socket(), that calls sendmsg() with
MSG_SPLICE_PAGES set instead of calling ->sendpage().
MSG_MORE is used to indicate if the sendmsg() is expected to be followed
with more data.
This allows multiple pipe-buffer pages to be passed in a single call in a
BVEC iterator, allowing the processing to be pushed down to a loop in the
protocol driver. This helps pave the way for passing multipage folios down
too.
Protocols that haven't been converted to handle MSG_SPLICE_PAGES yet should
just ignore it and do a normal sendmsg() for now - although that may be a
bit slower as it may copy everything.

It is necessary to allow MSG_SENDPAGE_* to be passed into ->sendmsg() to
allow sendmsg(MSG_SPLICE_PAGES) to replace ->sendpage(). Unblocking them
in the network protocol, however, allows these flags to be passed in by
userspace too[1].
Fix this by marking MSG_SENDPAGE_NOPOLICY, MSG_SENDPAGE_NOTLAST and
MSG_SENDPAGE_DECRYPTED as internal flags, which causes sendmsg() to object
if they are passed to sendmsg() by userspace. Network protocol ->sendmsg()
implementations can then allow them through.
Note that it should be possible to remove MSG_SENDPAGE_NOTLAST once
sendpage is removed as a whole slew of pages will be passed in in one go by
splice through sendmsg, with MSG_MORE being set if it has more data waiting
in the pipe.

mlx5-updates-2023-06-06
1) Support 4 ports VF LAG, part 2/2
2) Few extra trivial cleanup patches
Shay Drory Says:
================
Support 4 ports VF LAG, part 2/2
This series continues the series[1] "Support 4 ports VF LAG, part1/2".
This series adds support for 4 ports VF LAG (single FDB E-Switch).
This series of patches refactoring LAG code that make assumptions
about VF LAG supporting only two ports and then enable 4 ports VF LAG.
Patch 1:
- Fix for ib rep code
Patches 2-5:
- Refactors LAG layer.
Patches 6-7:
- Block LAG types which doesn't support 4 ports.
Patch 8:
- Enable 4 ports VF LAG.
This series specifically allows HCAs with 4 ports to create a VF LAG
with only 4 ports. It is not possible to create a VF LAG with 2 or 3
ports using HCAs that have 4 ports.
Currently, the Merged E-Switch feature only supports HCAs with 2 ports.
However, upcoming patches will introduce support for HCAs with 4 ports.
In order to activate VF LAG a user can execute:
devlink dev eswitch set pci/0000:08:00.0 mode switchdev
devlink dev eswitch set pci/0000:08:00.1 mode switchdev
devlink dev eswitch set pci/0000:08:00.2 mode switchdev
devlink dev eswitch set pci/0000:08:00.3 mode switchdev
ip link add name bond0 type bond
ip link set dev bond0 type bond mode 802.3ad
ip link set dev eth2 master bond0
ip link set dev eth3 master bond0
ip link set dev eth4 master bond0
ip link set dev eth5 master bond0
Where eth2, eth3, eth4 and eth5 are net-interfaces of pci/0000:08:00.0
pci/0000:08:00.1 pci/0000:08:00.2 pci/0000:08:00.3 respectively.
User can verify LAG state and type via debugfs:
/sys/kernel/debug/mlx5/0000\:08\:00.0/lag/state
/sys/kernel/debug/mlx5/0000\:08\:00.0/lag/type

Add a work abstraction at the cfg80211 level that will always
hold the wiphy_lock() for any work executed and therefore also
can be canceled safely (without waiting) while holding that.
This improves on what we do now as with the new wiphy works we
don't have to worry about locking while cancelling them safely.
Also, don't let such works run while the device is suspended,
since they'll likely need to interact with the device. Flush
them before suspend though.

A remote DoS vulnerability of RPL Source Routing is assigned CVE-2023-2156.
The Source Routing Header (SRH) has the following format:
0 1 2 3
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| Next Header | Hdr Ext Len | Routing Type | Segments Left |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| CmprI | CmprE | Pad | Reserved |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| |
. .
. Addresses[1..n] .
. .
| |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
The originator of an SRH places the first hop's IPv6 address in the IPv6
header's IPv6 Destination Address and the second hop's IPv6 address as
the first address in Addresses[1..n].
The CmprI and CmprE fields indicate the number of prefix octets that are
shared with the IPv6 Destination Address. When CmprI or CmprE is not 0,
Addresses[1..n] are compressed as follows:
1..n-1 : (16 - CmprI) bytes
n : (16 - CmprE) bytes
Segments Left indicates the number of route segments remaining. When the
value is not zero, the SRH is forwarded to the next hop. Its address
is extracted from Addresses[n - Segment Left + 1] and swapped with IPv6
Destination Address.
When Segment Left is greater than or equal to 2, the size of SRH is not
changed because Addresses[1..n-1] are decompressed and recompressed with
CmprI.
OTOH, when Segment Left changes from 1 to 0, the new SRH could have a
different size because Addresses[1..n-1] are decompressed with CmprI and
recompressed with CmprE.
Let's say CmprI is 15 and CmprE is 0. When we receive SRH with Segment
Left >= 2, Addresses[1..n-1] have 1 byte for each, and Addresses[n] has
16 bytes. When Segment Left is 1, Addresses[1..n-1] is decompressed to
16 bytes and not recompressed. Finally, the new SRH will need more room
in the header, and the size is (16 - 1) * (n - 1) bytes.
Here the max value of n is 255 as Segment Left is u8, so in the worst case,
we have to allocate 3825 bytes in the skb headroom. However, now we only
allocate a small fixed buffer that is IPV6_RPL_SRH_WORST_SWAP_SIZE (16 + 7
bytes). If the decompressed size overflows the room, skb_push() hits BUG()
below [0].
Instead of allocating the fixed buffer for every packet, let's allocate
enough headroom only when we receive SRH with Segment Left 1.
