STA MLD setup links may get removed if AP MLD remove the corresponding affiliated APs with Multi-Link reconfiguration as described in P802.11be_D3.0, section 35.3.6.2.2 Removing affiliated APs. Currently, there is no support to notify such operation to cfg80211 and userspace. Add support for the drivers to indicate STA MLD setup links removal to cfg80211 and notify the same to userspace.

Make the data access a bit nicer overall by using structs. There is a small change here to also accept a TBTT information length of eight bytes as we do not require the 20 MHz PSD information.

2023-06-09ipv4, ipv6: Use splice_eof() to flushDavid Howells3-0/+3
Allow splice to undo the effects of MSG_MORE after prematurely ending a splice/sendfile due to getting an EOF condition (->splice_read() returned 0) after splice had called sendmsg() with MSG_MORE set when the user didn't set MSG_MORE. For UDP, a pending packet will not be emitted if the socket is closed before it is flushed; with this change, it be flushed by ->splice_eof(). For TCP, it's not clear that MSG_MORE is actually effective.

2023-06-09splice, net: Add a splice_eof op to file-ops and socket-opsDavid Howells4-0/+4
Add an optional method, ->splice_eof(), to allow splice to indicate the premature termination of a splice to struct file_operations and struct proto_ops. This is called if sendfile() or splice() encounters all of the following conditions inside splice_direct_to_actor(): (1) the user did not set SPLICE_F_MORE (splice only), and (2) an EOF condition occurred (->splice_read() returned 0), and (3) we haven't read enough to fulfill the request (ie. len > 0 still), and (4) we have already spliced at least one byte. A further patch will modify the behaviour of SPLICE_F_MORE to always be passed to the actor if either the user set it or we haven't yet read sufficient data to fulfill the request.

2023-06-09splice, net: Use sendmsg(MSG_SPLICE_PAGES) rather than ->sendpage()David Howells2-2/+2
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.

2023-06-09net: Block MSG_SENDPAGE_* from being passed to sendmsg() by userspaceDavid Howells1-1/+3
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.

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.

Convert AF_ALG to use iov_iter_extract_pages() instead of iov_iter_get_pages(). This will pin pages or leave them unaltered rather than getting a ref on them as appropriate to the iterator. The pages need to be pinned for DIO-read rather than having refs taken on them to prevent VM copy-on-write from malfunctioning during a concurrent fork() (the result of the I/O would otherwise end up only visible to the child process and not the parent).
