====================
af_unix: Remove io_uring dead code in GC.
I will post another series that rewrites the garbage collector for
AF_UNIX socket.
This is a prep series to clean up changes to GC made by io_uring but
now not necessary.

Originally, the code related to garbage collection was all in garbage.c.
Commit f4e65870e5ce ("net: split out functions related to registering
inflight socket files") moved some functions to scm.c for io_uring and
added CONFIG_UNIX_SCM just in case AF_UNIX was built as module.
However, since commit 97154bcf4d1b ("af_unix: Kconfig: make CONFIG_UNIX
bool"), AF_UNIX is no longer built separately. Also, io_uring does not
support SCM_RIGHTS now.
Let's move the functions back to garbage.c

Since commit 705318a99a13 ("io_uring/af_unix: disable sending
io_uring over sockets"), io_uring's unix socket cannot be passed
via SCM_RIGHTS, so it does not contribute to cyclic reference and
no longer be candidate for garbage collection.
Also, commit 6e5e6d274956 ("io_uring: drop any code related to
SCM_RIGHTS") cleaned up SCM_RIGHTS code in io_uring.
Let's do it in AF_UNIX as well by reverting commit 0091bfc81741
("io_uring/af_unix: defer registered files gc to io_uring release")
and commit 10369080454d ("net: reclaim skb->scm_io_uring bit").

Currently, the test is racy and seems to not pass anymore.
In order to rectify it, aim on TCP_TW_RST.
Doesn't seem way too good with this sleep() part, but it seems as
a reasonable compromise for the test. There is a plan in-line comment on
how-to improve it, going to do it on the top, at this moment I want it
to run on netdev/patchwork selftests dashboard.
It also slightly changes tcp_ao-lib in order to get SO_ERROR propagated
to test_client_verify() return value.

As the names of (struct test_key) members didn't reflect whether the key
was used for TX or RX, the verification for the counters was done
incorrectly for asymmetrical selftests.
Rename these with _tx appendix and fix checks in verify_counters().
While at it, as the checks are now correct, introduce skip_counters_checks,
which is intended for tests where it's expected that a key that was set
with setsockopt(sk, IPPROTO_TCP, TCP_AO_INFO, ...) might had no chance
of getting used on the wire.
Fixes the following failures, exposed by the previous commit:
> not ok 51 server: Check current != rnext keys set before connect(): Counter pkt_good was expected to increase 0 => 0 for key 132:5
> not ok 52 server: Check current != rnext keys set before connect(): Counter pkt_good was not expected to increase 0 => 21 for key 137:10

The end_server() function only operates in the server thread
and always takes an accept socket instead of a listen socket as
its input argument. To align with this, invert the boolean values
used when calling verify_counters() within the end_server() function.
As a result of this typo, the test didn't correctly check for
the non-symmetrical scenario, where i.e. peer-A uses a key <100:200>
to send data, but peer-B uses another key <105:205> to send its data.
So, in simple words, different keys for TX and RX.

====================
net: phy: split at803x
This is the last patchset of a long series of cleanup and
preparation to make at803x better maintainable and permit
the addition of other QCOM PHY Families.
A shared library modules is created since many QCOM PHY share
similar/exact implementation and are reused.
This series doesn't introduce any new code but just move the
function around and introduce a new module for all the functions
that are shared between the 3 different PHY family.
Since the drivers are actually detached, new probe function are
introduced that allocate the specific priv struct for the PHYs.
After this patch, qca808x will be further generalized as LED
and cable test function are also used by the QCA807x PHYs.
This is just for reference and the additional function move will
be done on the relates specific series.
This is also needed in preparation for the introduction of
qca807x PHYs family and PHY package concept.

Almost all the QCA8081 PHY driver OPs are specific and only some of them
use the generic at803x.
To make the at803x code slimmer, move all the specific qca808x regs and
functions to a dedicated PHY driver.
Probe function and priv struct is reworked to allocate and use only the
qca808x specific data. Unused data from at803x PHY driver are dropped
from at803x priv struct.
Also a new Kconfig is introduced QCA808X_PHY, to compile the newly
introduced PHY driver for QCA8081 PHY.
As the Kconfig name starts with Qualcomm the same order is kept.

Deatch qca83xx PHY driver from at803x.
The QCA83xx PHYs implement specific function and doesn't use generic
at803x so it can be detached from the driver and moved to a dedicated
one.
Probe function and priv struct is reimplemented to allocate and use
only the qca83xx specific data. Unused data from at803x PHY driver
are dropped from at803x priv struct.
This is to make slimmer PHY drivers instead of including lots of bloat
that would never be used in specific SoC.

Andre Werner says:
====================
Prevent nullptr exceptions in ISR
In case phydev->irq is modified unconditionally to a valid IRQ, handling
the IRQ may lead to a nullptr exception if no interrupt handler is
registered to the phy driver. phy_interrupt calls a
phy_device->handle_interrupt unconditionally. And interrupts are enabled
in phy_connect_direct if phydev->irq is not equal to PHY_POLL or
PHY_MAC_INTERRUPT, so it does not check for a phy driver providing an ISR.
Adding an additonal check for a valid interrupt handler in phy_attach_direct
function, and falling back to polling mode if not, should prevent for
such nullptr exceptions.
Moreover, the ADIN1100 phy driver is extended with an interrupt handler
for changes in the link status.

Not all mv88e6xxx device support C45 read/write operations. Those
which do not return -EOPNOTSUPP. However, when phylib scans the bus,
it considers this fatal, and the probe of the MDIO bus fails, which in
term causes the mv88e6xxx probe as a whole to fail.
When there is no device on the bus for a given address, the pull up
resistor on the data line results in the read returning 0xffff. The
phylib core code understands this when scanning for devices on the
bus. C45 allows multiple devices to be supported at one address, so
phylib will perform a few reads at each address, so although thought
not the most efficient solution, it is a way to avoid fatal
errors. Make use of this as a minimal fix for stable to fix the
probing problems.
Follow up patches will rework how C45 operates to make it similar to
C22 which considers -ENODEV as a none-fatal, and swap mv88e6xxx to
using this.

The patch "netfilter: ipset: fix race condition between swap/destroy
and kernel side add/del/test", commit 28628fa9 fixes a race condition.
But the synchronize_rcu() added to the swap function unnecessarily slows
it down: it can safely be moved to destroy and use call_rcu() instead.
Eric Dumazet pointed out that simply calling the destroy functions as
rcu callback does not work: sets with timeout use garbage collectors
which need cancelling at destroy which can wait. Therefore the destroy
functions are split into two: cancelling garbage collectors safely at
executing the command received by netlink and moving the remaining
part only into the rcu callback.

The annotation says in sctp_new(): "If it is a shutdown ack OOTB packet, we
expect a return shutdown complete, otherwise an ABORT Sec 8.4 (5) and (8)".
However, it does not check SCTP_CID_SHUTDOWN_ACK before setting vtag[REPLY]
in the conntrack entry(ct).
Because of that, if the ct in Router disappears for some reason in [1]
with the packet sequence like below:
Client > Server: sctp (1) [INIT] [init tag: 3201533963]
Server > Client: sctp (1) [INIT ACK] [init tag: 972498433]
Client > Server: sctp (1) [COOKIE ECHO]
Server > Client: sctp (1) [COOKIE ACK]
Client > Server: sctp (1) [DATA] (B)(E) [TSN: 3075057809]
Server > Client: sctp (1) [SACK] [cum ack 3075057809]
Server > Client: sctp (1) [HB REQ]
(the ct in Router disappears somehow) <-------- [1]
Client > Server: sctp (1) [HB ACK]
Client > Server: sctp (1) [DATA] (B)(E) [TSN: 3075057810]
Client > Server: sctp (1) [DATA] (B)(E) [TSN: 3075057810]
Client > Server: sctp (1) [HB REQ]
Client > Server: sctp (1) [DATA] (B)(E) [TSN: 3075057810]
Client > Server: sctp (1) [HB REQ]
Client > Server: sctp (1) [ABORT]
when processing HB ACK packet in Router it calls sctp_new() to initialize
the new ct with vtag[REPLY] set to HB_ACK packet's vtag.
Later when sending DATA from Client, all the SACKs from Server will get
dropped in Router, as the SACK packet's vtag does not match vtag[REPLY]
in the ct. The worst thing is the vtag in this ct will never get fixed
by the upcoming packets from Server.
This patch fixes it by checking SCTP_CID_SHUTDOWN_ACK before setting
vtag[REPLY] in the ct in sctp_new() as the annotation says. With this
fix, it will leave vtag[REPLY] in ct to 0 in the case above, and the
next HB REQ/ACK from Server is able to fix the vtag as its value is 0
in nf_conntrack_sctp_packet().

commit c7aab4f17021 ("netfilter: nf_conntrack_tcp: re-init for syn packets
only") introduces a bug where SYNs in ORIGINAL direction on reused 5-tuple
result in incorrect window scale negotiation. This commit merged the SYN
re-initialization and simultaneous open or SYN retransmits cases. Merging
this block added the logic in tcp_init_sender() that performed window scale
negotiation to the retransmitted syn case. Previously. this would only
result in updating the sender's scale and flags. After the merge the
additional logic results in improperly clearing the scale in ORIGINAL
direction before any packets in the REPLY direction are received. This
results in packets incorrectly being marked invalid for being
out-of-window.
This can be reproduced with the following trace:
Packet Sequence:
> Flags [S], seq 1687765604, win 62727, options [.. wscale 7], length 0
> Flags [S], seq 1944817196, win 62727, options [.. wscale 7], length 0
In order to fix the issue, only evaluate window negotiation for packets
in the REPLY direction. This was tested with simultaneous open, fast
open, and the above reproduction.

The test sends packets and compares enqueue, transmit and Ack
timestamps with expected values. It installs netem delays to increase
latency between these points.
The test proves flaky in virtual environment (vng). Increase the
delays to reduce variance. Scale measurement tolerance accordingly.
Time sensitive tests are difficult to calibrate. Increasing delays 10x
also increases runtime 10x, for one. And it may still prove flaky at
some rate.

Last three patches, from myself, tweak kconfig logic a little to
permit a kernel configuration that can run iptables-over-nftables
but not classic (setsockopt) iptables.
Such builds lack the builtin-filter/mangle/raw/nat/security tables,
the set/getsockopt interface and the "old blob format"
interpreter/traverser. For now, this is 'oldconfig friendly', users
need to manually deselect existing config options for this.

Geert Uytterhoeven reported that commit 4e244c10eab3 ("kconfig: remove
unneeded symbol_empty variable") changed the default value of
CONFIG_LOG_CPU_MAX_BUF_SHIFT from 12 to 0.
As it turned out, this is an undefined behavior because sym_calc_value()
stopped setting the sym->curr.tri field for 'int', 'hex', and 'string'
symbols.
This commit restores the original behavior, where 'int', 'hex', 'string'
symbols are interpreted as false if used in boolean contexts.
CONFIG_LOG_CPU_MAX_BUF_SHIFT will default to 12 again, irrespective
of CONFIG_BASE_SMALL. Presumably, this is not the intended behavior,
as already reported [1], but this is another issue that should be
addressed by a separate patch.

The new installkernel application that is now included in systemd-udev
package allows installation although destination files are already present
in the boot directory of the kernel package, but is failing with the
implemented workaround for the old installkernel application from grubby
package.
For the new installkernel application, as Davide says:
<<The %post currently does a shuffling dance before calling installkernel.
This isn't actually necessary afaict, and the current implementation
ends up triggering downstream issues such as
https://github.com/systemd/systemd/issues/29568
This commit simplifies the logic to remove the shuffling. For reference,
the original logic was added in commit 3c9c7a14b627("rpm-pkg: add %post
section to create initramfs and grub hooks").>>
But we need to keep the old behavior as well, because the old installkernel
application from grubby package, does not allow this simplification and
we need to be backward compatible to avoid issues with the different
packages.
Mimic Fedora shipping process and store vmlinuz, config amd System.map
in the module directory instead of the boot directory. In this way, we will
avoid the commented problem for all the cases, because the new destination
files are not going to exist in the boot directory of the kernel package.
Replace installkernel tool with kernel-install tool, because the latter is
more complete.
Besides, after installkernel tool execution, check to complete if the
correct package files vmlinuz, System.map and config files are present
in /boot directory, and if necessary, copy manually for install operation.
In this way, take into account if files were not previously copied from
/usr/lib/kernel/install.d/* scripts and if the suitable files for the
requested package are present (it could be others if the rpm files were
replace with a new pacakge with the same release and a different build).
Tested with Fedora 38, Fedora 39, RHEL 9, Oracle Linux 9.3,
openSUSE Tumbleweed and openMandrive ROME, using dnf/zypper and rpm tools.

This is needed for the future (post make-4.4.1) versions of gnu make.
Starting from https://git.savannah.gnu.org/cgit/make.git/commit/?id=07fcee35f058a876447c8a021f9eb1943f902534
gnu make won't allow conditionals to follow recipe prefix.
For example there is a tab followed by ifeq on line 324 in the root Makefile.
With the new make this conditional causes the following
$ make cpu.o
/home/dgoncharov/src/linux-kbuild/Makefile:2063: *** missing 'endif'. Stop.
make: *** [Makefile:240: __sub-make] Error 2
This patch replaces tabs followed by conditionals with 8 spaces.

Aiden Leong reported modpost fails to build on macOS since commit
16a473f60edc ("modpost: inform compilers that fatal() never returns"):
scripts/mod/modpost.c:93:21: error: aliases are not supported on darwin
Nathan's research indicates that Darwin seems to support weak aliases
at least [1]. Although the situation might be improved in future Clang
versions, we can achieve a similar outcome without relying on it.
This commit makes fatal() a macro of error() + exit(1) in modpost.h, as
compilers recognize that exit() never returns.

There are two points with the calculation of RX buffer size which are
not optimal:
1. dev->mtu is a mutual parameter and it's currently initialized with
QCAFRM_MAX_MTU. But for RX buffer size calculation we always need the
maximum possible MTU. So better use the define directly.
2. This magic number 4 represent the hardware generated frame length
which is specific to SPI. We better replace this with the suitable
define.
There is no functional change.
