This change introduces a prctl that allows the user program to control
which PAC keys are enabled in a particular task. The main reason
why this is useful is to enable a userspace ABI that uses PAC to
sign and authenticate function pointers and other pointers exposed
outside of the function, while still allowing binaries conforming
to the ABI to interoperate with legacy binaries that do not sign or
authenticate pointers.
The idea is that a dynamic loader or early startup code would issue
this prctl very early after establishing that a process may load legacy
binaries, but before executing any PAC instructions.
This change adds a small amount of overhead to kernel entry and exit
due to additional required instruction sequences.
On a DragonBoard 845c (Cortex-A75) with the powersave governor, the
overhead of similar instruction sequences was measured as 4.9ns when
simulating the common case where IA is left enabled, or 43.7ns when
simulating the uncommon case where IA is disabled. These numbers can
be seen as the worst case scenario, since in more realistic scenarios
a better performing governor would be used and a newer chip would be
used that would support PAC unlike Cortex-A75 and would be expected
to be faster than Cortex-A75.
On an Apple M1 under a hypervisor, the overhead of the entry/exit
instruction sequences introduced by this patch was measured as 0.3ns
in the case where IA is left enabled, and 33.0ns in the case where
IA is disabled.

Per net/bpf/test_run.c, particular prog types have additional
restrictions around the parameters that can be provided, so document
these in the header.
I didn't bother documenting the limitation on duration for raw

This adds two new POLL_ADD flags, IORING_POLL_UPDATE_EVENTS and
IORING_POLL_UPDATE_USER_DATA. As with the other POLL_ADD flag, these are
masked into sqe->len. If set, the POLL_ADD will have the following
behavior:
- sqe->addr must contain the the user_data of the poll request that
needs to be modified. This field is otherwise invalid for a POLL_ADD
command.
- If IORING_POLL_UPDATE_EVENTS is set, sqe->poll_events must contain the
new mask for the existing poll request. There are no checks for whether
these are identical or not, if a matching poll request is found, then it
is re-armed with the new mask.
- If IORING_POLL_UPDATE_USER_DATA is set, sqe->off must contain the new
user_data for the existing poll request.
A POLL_ADD with any of these flags set may complete with any of the
following results:
1) 0, which means that we successfully found the existing poll request
specified, and performed the re-arm procedure. Any error from that
re-arm will be exposed as a completion event for that original poll
request, not for the update request.
2) -ENOENT, if no existing poll request was found with the given
user_data.
3) -EALREADY, if the existing poll request was already in the process of
being removed/canceled/completing.
4) -EACCES, if an attempt was made to modify an internal poll request
(eg not one originally issued ass IORING_OP_POLL_ADD).
The usual -EINVAL cases apply as well, if any invalid fields are set
in the sqe for this command type.

The default io_uring poll mode is one-shot, where once the event triggers,
the poll command is completed and won't trigger any further events. If
we're doing repeated polling on the same file or socket, then it can be
more efficient to do multishot, where we keep triggering whenever the
event becomes true.
This deviates from the usual norm of having one CQE per SQE submitted. Add
a CQE flag, IORING_CQE_F_MORE, which tells the application to expect
further completion events from the submitted SQE. Right now the only user
of this is POLL_ADD in multishot mode.
Since sqe->poll_events is using the space that we normally use for adding
flags to commands, use sqe->len for the flag space for POLL_ADD. Multishot
mode is selected by setting IORING_POLL_ADD_MULTI in sqe->len. An
application should expect more CQEs for the specificed SQE if the CQE is
flagged with IORING_CQE_F_MORE. In multishot mode, only cancelation or an
error will terminate the poll request, in which case the flag will be
cleared.

Define get_module_eeprom_by_page() ethtool callback and implement
netlink infrastructure.
get_module_eeprom_by_page() allows network drivers to dump a part of
module's EEPROM specified by page and bank numbers along with offset and
length. It is effectively a netlink replacement for get_module_info()
and get_module_eeprom() pair, which is needed due to emergence of
complex non-linear EEPROM layouts.

Oded writes:
This tag contains habanalabs driver changes for v5.13:
- Add support to reset device after the user closes the file descriptor.
Because we support a single user, we can reset the device (if needs to)
after a user closes its file descriptor to make sure the device is in
idle and clean state for the next user.
- Add a new feature to allow the user to wait on interrupt. This is needed
for future ASICs
- Replace GFP_ATOMIC with GFP_KERNEL wherever possible and add code to
support failure of allocating with GFP_ATOMIC.
- Update code to support the latest firmware image:
- More security features are done in the firmware
- Remove hard-coded assumptions and replace them with values that are
sent to the firmware on loading.
- Print device unusable error
- Reset device in case the communication between driver and firmware
gets out of sync.
- Support new PCI device ids for secured GAUDI.
- Expose current power draw through the INFO IOCTL.
- Support resetting the device upon a request from the BMC (through F/W).
- Always use only a single MSI in GAUDI, due to H/W limitation.
- Improve data-path code by taking out code from spinlock protection.
- Allow user to specify custom timeout per Command Submission.
- Some enhancements to debugfs.
- Various minor changes and improvements.

When async binder buffer got exhausted, some normal oneway transactions
will also be discarded and may cause system or application failures. By
that time, the binder debug information we dump may not be relevant to
the root cause. And this issue is difficult to debug if without the
backtrace of the thread sending spam.
This change will send BR_ONEWAY_SPAM_SUSPECT to userspace when oneway
spamming is detected, request to dump current backtrace. Oneway spamming
will be reported only once when exceeding the threshold (target process
dips below 80% of its oneway space, and current process is responsible for
either more than 50 transactions, or more than 50% of the oneway space).
And the detection will restart when the async buffer has returned to a
healthy state.

Recompiling with the new extended version of struct rfkill_event
broke systemd in *two* ways:
- It used "sizeof(struct rfkill_event)" to read the event, but
then complained if it actually got something != 8, this broke
it on new kernels (that include the updated API);
- It used sizeof(struct rfkill_event) to write a command, but
didn't implement the intended expansion protocol where the
kernel returns only how many bytes it accepted, and errored
out due to the unexpected smaller size on kernels that didn't
include the updated API.
Even though systemd has now been fixed, that fix may not be always
deployed, and other applications could potentially have similar
issues.
As such, in the interest of avoiding regressions, revert the
default API "struct rfkill_event" back to the original size.
Instead, add a new "struct rfkill_event_ext" that extends it by
the new field, and even more clearly document that applications
should be prepared for extensions in two ways:
* write might only accept fewer bytes on older kernels, and
will return how many to let userspace know which data may
have been ignored;
* read might return anything between 8 (the original size) and
whatever size the application sized its buffer at, indicating
how much event data was supported by the kernel.
Perhaps that will help avoid such issues in the future and we
won't have to come up with another version of the struct if we
ever need to extend it again.
Applications that want to take advantage of the new field will
have to be modified to use struct rfkill_event_ext instead now,
which comes with the danger of them having already been updated
to use it from 'struct rfkill_event', but I found no evidence
of that, and it's still relatively new.

Long Term Reference (LTR) frames are the frames that are encoded
sometime in the past and stored in the DPB buffer list to be used
as reference to encode future frames.
This change adds controls to enable this feature.

The MPTCP reset option allows to carry a mptcp-specific error code that
provides more information on the nature of a connection reset.
Reset option data received gets stored in the subflow context so it can
be sent to userspace via the 'subflow closed' netlink event.
When a subflow is closed, the desired error code that should be sent to
the peer is also placed in the subflow context structure.
If a reset is sent before subflow establishment could complete, e.g. on
HMAC failure during an MP_JOIN operation, the mptcp skb extension is
used to store the reset information.

The big top of the file comment talk about grand plans that never
happened, so remove them to not confuse the readers. Also mark the
devname and volname fields as ignored as they were never used by the
kernel.

Reusing BPF_SK_SKB_STREAM_VERDICT is possible but its name is
confusing and more importantly we still want to distinguish them
from user-space. So we can just reuse the stream verdict code but
introduce a new type of eBPF program, skb_verdict. Users are not
allowed to attach stream_verdict and skb_verdict programs to the
same map.

Add FEC API to netlink.
This is not a 1-to-1 conversion.
FEC settings already depend on link modes to tell user which
modes are supported. Take this further an use link modes for
manual configuration. Old struct ethtool_fecparam is still
used to talk to the drivers, so we need to translate back
and forth. We can revisit the internal API if number of FEC
encodings starts to grow.
Enforce only one active FEC bit (by using a bit position
rather than another mask).

There is a regular need in the kernel to provide a way to declare having
a dynamically sized set of trailing elements in a structure. Kernel code
should always use “flexible array members”[1] for these cases. The older
style of one-element or zero-length arrays should no longer be used[2].
Use an anonymous union with a couple of anonymous structs in order to
keep userspace unchanged:
$ pahole -C nfs_fhbase_new fs/nfsd/nfsfh.o
struct nfs_fhbase_new {
union {
struct {
__u8 fb_version_aux; /* 0 1 */
__u8 fb_auth_type_aux; /* 1 1 */
__u8 fb_fsid_type_aux; /* 2 1 */
__u8 fb_fileid_type_aux; /* 3 1 */
__u32 fb_auth[1]; /* 4 4 */
}; /* 0 8 */
struct {
__u8 fb_version; /* 0 1 */
__u8 fb_auth_type; /* 1 1 */
__u8 fb_fsid_type; /* 2 1 */
__u8 fb_fileid_type; /* 3 1 */
__u32 fb_auth_flex[0]; /* 4 0 */
}; /* 0 4 */
}; /* 0 8 */
/* size: 8, cachelines: 1, members: 1 */
/* last cacheline: 8 bytes */
};
Also, this helps with the ongoing efforts to enable -Warray-bounds by
fixing the following warnings:
