As of commit 7d1d865181 ("[SCSI] libsas: fix false positive 'device
attached' conditions"), reset the phy->entacted_sas_addr address to a
zero-address when the link rate is less than 1.5G.
Currently we find that when a new device is attached, and the link rate is
less than 1.5G, but the device type is not NO_DEVICE, for example: the link
rate is SAS_PHY_RESET_IN_PROGRESS and the device type is stp. After setting
the phy->entacted_sas_addr address to the zero address, the port will
continue to be created for the phy with the zero-address, and other phys
with the zero-address will be tried to be added to the new port:
[562240.051197] sas: ex 500e004aaaaaaa1f phy19:U:0 attached: 0000000000000000 (no device)
// phy19 is deleted but still on the parent port's phy_list
[562240.062536] sas: ex 500e004aaaaaaa1f phy0 new device attached
[562240.062616] sas: ex 500e004aaaaaaa1f phy00:U:5 attached: 0000000000000000 (stp)
[562240.062680] port-7:7:0: trying to add phy phy-7:7:19 fails: it's already part of another port
Therefore, it should be the same as sas_get_phy_attached_dev(). Only when
device_type is SAS_PHY_UNUSED, sas_address is set to the 0 address.

We found that when ex_phy was attached and added to the parent wide port,
ex_phy->port was not set, resulting in sas_unregister_devs_sas_addr() not
calling sas_port_delete_phy() when deleting the phy, and the deleted phy
was still on the parent wide port's phy_list.
When we use sas_port_add_ex_phy() to set ex_phy->port to solve the above
problem, we find that after all the phys of the parent_port are removed and
the number of phy becomes 0, the parent_port will not be set to NULL. This
causes the freed parent port to be used when attaching a new ex_phy in
sas_ex_add_parent_port().
Use sas_port_add_ex_phy() instead of sas_port_add_phy() to set ex_phy->port
when ex_phy is added to the parent port, and set ex_dev->parent_port to
NULL when the number of phy on the port becomes 0.

Adding write support to the buffer-dma code is easy - the write()
function basically needs to do the exact same thing as the read()
function: dequeue a block, read or write the data, enqueue the block
when entirely processed.
Therefore, the iio_buffer_dma_read() and the new iio_buffer_dma_write()
now both call a function iio_buffer_dma_io(), which will perform this
task.
Note that we preemptively reset block->bytes_used to the buffer's size
in iio_dma_buffer_request_update(), as in the future the
iio_dma_buffer_enqueue() function won't reset it.

We currently insist on disabling PAuth on vcpu_load(), and get to
enable it on first guest use of an instruction or a key (ignoring
the NV case for now).
It isn't clear at all what this is trying to achieve: guests tend
to use PAuth when available, and nothing forces you to expose it
to the guest if you don't want to. This also isn't totally free:
we take a full GPR save/restore between host and guest, only to
write ten 64bit registers. The "value proposition" escapes me.
So let's forget this stuff and enable PAuth eagerly if exposed to
the guest. This results in much simpler code. Performance wise,
that's not bad either (tested on M2 Pro running a fully automated
Debian installer as the workload):
- On a non-NV guest, I can see reduction of 0.24% in the number
of cycles (measured with perf over 10 consecutive runs)
- On a NV guest (L2), I see a 2% reduction in wall-clock time
(measured with 'time', as M2 doesn't have a PMUv3 and NV
doesn't support it either)
So overall, a much reduced complexity and a (small) performance
improvement.

A significant part of the FEAT_NV extension is to trap ERET
instructions so that the hypervisor gets a chance to switch
from a vEL2 L1 guest to an EL1 L2 guest.
But this also has the unfortunate consequence of trapping ERET
in unsuspecting circumstances, such as staying at vEL2 (interrupt
handling while being in the guest hypervisor), or returning to host
userspace in the case of a VHE guest.
Although we already make some effort to handle these ERET quicker
by not doing the put/load dance, it is still way too far down the
line for it to be efficient enough.
For these cases, it would ideal to ERET directly, no question asked.
Of course, we can't do that. But the next best thing is to do it as
early as possible, in fixup_guest_exit(), much as we would handle
FPSIMD exceptions.

Crucially, the architecture doesn't mandate that address and generic
authentication implement the *same* flavour. This would make

So only allow PAuth support for KVM on systems that are not totally

The device's manual (PRM - Programmer's Reference Manual) classifies the
trap that is used to deliver EMAD responses as an "event trap". Among
other things, it means that the only actions that can be associated with
the trap are TRAP and FORWARD (NOP).
Currently, during driver de-initialization the driver unregisters the
trap by setting its action to DISCARD, which violates the above
guideline. Future firmware versions will prevent such misuses by
returning an error. This does not prevent the driver from working, but
an error will be printed to the kernel log during module removal /
devlink reload:

====================
testing: make netfilter selftests functional in vng environment
This is the second batch of the netfilter selftest move.
Changes since v1:
- makefile and kernel config are updated to have all required features
- fix makefile with missing bits to make kselftest-install work
- test it via vng as per
https://github.com/linux-netdev/nipa/wiki/How-to-run-netdev-selftests-CI-style
(Thanks Jakub!)
- squash a few fixes, e.g. nft_queue.sh v1 had a race w. NFNETLINK_QUEUE=m
- add a settings file with 8m timeout, for nft_concat_range.sh sake.
That script can be sped up a bit, I think, but its not contained in
this batch yet.
- toss the first two bogus rebase artifacts (Matthieu Baerts)
scripts are moved to lib.sh infra. This allows to use busywait helper
and ditch various 'sleep 2' all over the place.
Tested on Fedora 39:
vng --build --config tools/testing/selftests/net/netfilter/config
make -C tools/testing/selftests/ TARGETS=net/netfilter
vng -v --run . --user root --cpus 2 -- \
make -C tools/testing/selftests TARGETS=net/netfilter run_tests
... all tests pass except nft_audit.sh which SKIPs due to nft version mismatch
(Fedora is on nft 1.0.7 which lacks reset keyword support).
Missing/WIP bits:
- speed up nf_concat_range.sh test
- extend flowtable selftest
- shellcheck fixups for remaining scripts

Jakub reports the Makefile missed a few updates to make kselftest-install
work for the netfilter tests and points out that config file lacks many
dependencies such as VETH support.
The settings file (timeout 8m) is added for nft_concat_range.sh script
which can take several minutes to complete.

This testcase doesn't work if auditd is running, audit_logread will not
receive any data in that case.
Add a nftables feature test for the reset keyword and skip this test
if that fails.
While at it, do a few minor shellcheck cleanups.

While at it: No need for iperf here, use socat.
This also reduces the script runtime.

Intentional changes:
- Use socat instead of netcat
- Use a temporary file instead of pipe, else packets do not match
"-m string" rules, multiple writes to the pipe cause multiple packets,
but this needs only one to work.

Also do shellcheck cleanups here, no functional changes intended.
When running tests via vng tool, the packetpath insertion test fails:
dd: failed to open '/dev/stdout': Device or resource busy
Just omit 'of=' and this will work as intended.
