This is the Intel version of a confidential computing solution called
Trust Domain Extensions (TDX). This series adds support to run the
kernel as part of a TDX guest. It provides similar guest protections to
AMD's SEV-SNP like guest memory and register state encryption, memory
integrity protection and a lot more.
Design-wise, it differs from AMD's solution considerably: it uses
a software module which runs in a special CPU mode called (Secure
Arbitration Mode) SEAM. As the name suggests, this module serves as sort
of an arbiter which the confidential guest calls for services it needs
during its lifetime.
Just like AMD's SNP set, this series reworks and streamlines certain
parts of x86 arch code so that this feature can be properly accomodated.

Add to confidential guests the necessary memory integrity protection
against malicious hypervisor-based attacks like data replay, memory
remapping and others, thus achieving a stronger isolation from the
hypervisor.
At the core of the functionality is a new structure called a reverse
map table (RMP) with which the guest has a say in which pages get
assigned to it and gets notified when a page which it owns, gets
accessed/modified under the covers so that the guest can take an
appropriate action.
In addition, add support for the whole machinery needed to launch a SNP
guest, details of which is properly explained in each patch.
And last but not least, the series refactors and improves parts of the
previous SEV support so that the new code is accomodated properly and
not just bolted on.

Joanne Koong says:
====================
This patchset implements the basics of dynamic pointers in bpf.
A dynamic pointer (struct bpf_dynptr) is a pointer that stores extra metadata
alongside the address it points to. This abstraction is useful in bpf given
that every memory access in a bpf program must be safe. The verifier and bpf
helper functions can use the metadata to enforce safety guarantees for things
such as dynamically sized strings and kernel heap allocations.
From the program side, the bpf_dynptr is an opaque struct and the verifier
will enforce that its contents are never written to by the program.
It can only be written to through specific bpf helper functions.
There are several uses cases for dynamic pointers in bpf programs. Some
examples include: dynamically sized ringbuf reservations without extra
memcpys, dynamic string parsing and memory comparisons, dynamic memory
allocations that can be persisted in maps, and dynamic + ergonomic parsing of
sk_buff and xdp_md packet data.
At a high-level, the patches are as follows:
1/6 - Adds verifier support for dynptrs
2/6 - Adds bpf_dynptr_from_mem (local dynptr)
3/6 - Adds dynptr support for ring buffers
4/6 - Adds bpf_dynptr_read and bpf_dynptr_write
5/6 - Adds dynptr data slices (ptr to the dynptr data)
6/6 - Tests to check that the verifier rejects invalid cases and passes valid ones
This is the first dynptr patchset in a larger series. The next series of
patches will add dynptrs that support dynamic memory allocations that can also
be persisted in maps, support for parsing packet data through dynptrs, convenience
helpers for using dynptrs as iterators, and more helper functions for interacting
with strings and memory dynamically.

This patch adds tests for dynptrs, which include cases that the
verifier needs to reject (for example, a bpf_ringbuf_reserve_dynptr
without a corresponding bpf_ringbuf_submit/discard_dynptr) as well
as cases that should successfully pass.

This patch adds a new helper function
void *bpf_dynptr_data(struct bpf_dynptr *ptr, u32 offset, u32 len);
which returns a pointer to the underlying data of a dynptr. *len*
must be a statically known value. The bpf program may access the returned
data slice as a normal buffer (eg can do direct reads and writes), since
the verifier associates the length with the returned pointer, and
enforces that no out of bounds accesses occur.

This patch adds two helper functions, bpf_dynptr_read and
bpf_dynptr_write:
long bpf_dynptr_read(void *dst, u32 len, struct bpf_dynptr *src, u32 offset);
long bpf_dynptr_write(struct bpf_dynptr *dst, u32 offset, void *src, u32 len);
The dynptr passed into these functions must be valid dynptrs that have
been initialized.

Currently, our only way of writing dynamically-sized data into a ring
buffer is through bpf_ringbuf_output but this incurs an extra memcpy
cost. bpf_ringbuf_reserve + bpf_ringbuf_commit avoids this extra
memcpy, but it can only safely support reservation sizes that are
statically known since the verifier cannot guarantee that the bpf
program won’t access memory outside the reserved space.
The bpf_dynptr abstraction allows for dynamically-sized ring buffer
reservations without the extra memcpy.
There are 3 new APIs:
long bpf_ringbuf_reserve_dynptr(void *ringbuf, u32 size, u64 flags, struct bpf_dynptr *ptr);
void bpf_ringbuf_submit_dynptr(struct bpf_dynptr *ptr, u64 flags);
void bpf_ringbuf_discard_dynptr(struct bpf_dynptr *ptr, u64 flags);
These closely follow the functionalities of the original ringbuf APIs.
For example, all ringbuffer dynptrs that have been reserved must be
either submitted or discarded before the program exits.

This patch adds a new api bpf_dynptr_from_mem:
long bpf_dynptr_from_mem(void *data, u32 size, u64 flags, struct bpf_dynptr *ptr);
which initializes a dynptr to point to a bpf program's local memory. For now
only local memory that is of reg type PTR_TO_MAP_VALUE is supported.

This patch adds the bulk of the verifier work for supporting dynamic
pointers (dynptrs) in bpf.
A bpf_dynptr is opaque to the bpf program. It is a 16-byte structure
defined internally as:
struct bpf_dynptr_kern {
void *data;
u32 size;
u32 offset;
} __aligned(8);
The upper 8 bits of *size* is reserved (it contains extra metadata about
read-only status and dynptr type). Consequently, a dynptr only supports
memory less than 16 MB.
There are different types of dynptrs (eg malloc, ringbuf, ...). In this
patchset, the most basic one, dynptrs to a bpf program's local memory,
is added. For now only local memory that is of reg type PTR_TO_MAP_VALUE
is supported.
In the verifier, dynptr state information will be tracked in stack
slots. When the program passes in an uninitialized dynptr
(ARG_PTR_TO_DYNPTR | MEM_UNINIT), the stack slots corresponding
to the frame pointer where the dynptr resides at are marked
STACK_DYNPTR. For helper functions that take in initialized dynptrs (eg
bpf_dynptr_read + bpf_dynptr_write which are added later in this
patchset), the verifier enforces that the dynptr has been initialized
properly by checking that their corresponding stack slots have been
marked as STACK_DYNPTR.
The 6th patch in this patchset adds test cases that the verifier should
successfully reject, such as for example attempting to use a dynptr
after doing a direct write into it inside the bpf program.

This driver does a lot of casting of smaller buffers to
struct kvaser_cmd_ext, GCC 12 does not like that:
| drivers/net/can/usb/kvaser_usb/kvaser_usb_hydra.c:489:65: warning: array subscript ‘struct kvaser_cmd_ext[0]’ is partly outside array bounds of ‘unsigned char[32]’ [-Warray-bounds]
| drivers/net/can/usb/kvaser_usb/kvaser_usb_hydra.c:489:23: note: in expansion of macro ‘le16_to_cpu’
| 489 | ret = le16_to_cpu(((struct kvaser_cmd_ext *)cmd)->len);
| | ^~~~~~~~~~~
Temporarily silence this warning (move it to W=1 builds).

The handling of connection failures shall be handled by the request
completion callback as already done by hci_cs_le_create_conn, also make
sure to use hci_conn_failed instead of hci_le_conn_failed as the later
don't actually call hci_conn_del to cleanup.

Pull io_uring 'more data in socket' support from Jens Axboe:
"To be able to fully utilize the 'poll first' support in the core
io_uring branch, it's advantageous knowing if the socket was empty
after a receive. This adds support for that"
* tag 'for-5.19/io_uring-net-2022-05-22' of git://git.kernel.dk/linux-block:
io_uring: return hint on whether more data is available after receive
tcp: pass back data left in socket after receive
