tools: ynl: fix mixing ops and notifications on one socket
The multi message support loosened the connection between the request
and response handling, as we can now submit multiple requests before
we start processing responses. Passing the attr set to NlMsgs decoding
no longer makes sense (if it ever did), attr set may differ message
by messsage. Isolate the part of decoding responsible for attr-set
specific interpretation and call it once we identified the correct op.
Without this fix performing SET operation on an ethtool socket, while
being subscribed to notifications causes:
# File "tools/net/ynl/pyynl/lib/ynl.py", line 1096, in _op
# Exception| return self._ops(ops)[0]
# Exception| ~~~~~~~~~^^^^^
# File "tools/net/ynl/pyynl/lib/ynl.py", line 1040, in _ops
# Exception| nms = NlMsgs(reply, attr_space=op.attr_set)
# Exception| ^^^^^^^^^^^
The value of op we use on line 1040 is stale, it comes form the previous
loop. If a notification comes before a response we will update op to None
and the next iteration thru the loop will break with the trace above.

calipso: Fix null-ptr-deref in calipso_req_{set,del}attr().
syzkaller reported a null-ptr-deref in sock_omalloc() while allocating
a CALIPSO option. [0]
The NULL is of struct sock, which was fetched by sk_to_full_sk() in
calipso_req_setattr().
Since commit a1a5344ddbe8 ("tcp: avoid two atomic ops for syncookies"),
reqsk->rsk_listener could be NULL when SYN Cookie is returned to its
client, as hinted by the leading SYN Cookie log.
Here are 3 options to fix the bug:
1) Return 0 in calipso_req_setattr()
2) Return an error in calipso_req_setattr()
3) Alaways set rsk_listener
1) is no go as it bypasses LSM, but 2) effectively disables SYN Cookie
for CALIPSO. 3) is also no go as there have been many efforts to reduce
atomic ops and make TCP robust against DDoS. See also commit 3b24d854cb35
("tcp/dccp: do not touch listener sk_refcnt under synflood").
As of the blamed commit, SYN Cookie already did not need refcounting,
and no one has stumbled on the bug for 9 years, so no CALIPSO user will
care about SYN Cookie.
Let's return an error in calipso_req_setattr() and calipso_req_delattr()
in the SYN Cookie case.
This can be reproduced by [1] on Fedora and now connect() of nc times out.

very first GuC load attempt on GT0 (from xe_gt_init_hwconfig) is done
before the GT1 GuC objects are initialized, so things go bad when the

status in the functions called during wedge.

When the option to trace function arguments in the function graph

The issue is that it doesn't check if function graph tracing is

disable it and re-enable it (which will actually enable it even

Revert "mtd: core: always create master device"
The idea behind this patch was to always let a "master" mtd device
available to anchor runtime PM. Historically, there was no mtd device
representing the whole storage as soon as partitions were coming into
play. The introduction of CONFIG_MTD_PARTITIONED_MASTER allowed to keep
this "master" device, but was not enabled by default to avoid breaking
existing users (otherwise the mtd device numbering would be totally
messed up with an off by 1, at least).
The approach of adding an mtd_master class on top of partitioned mtd
devices is breaking the mtd core in many creative ways, so better think
again this approach and revert the faulty changes for now.

tcp: fix tcp_packet_delayed() for tcp_is_non_sack_preventing_reopen() behavior
After the following commit from 2024:
commit e37ab7373696 ("tcp: fix to allow timestamp undo if no retransmits were sent")
...there was buggy behavior where TCP connections without SACK support
could easily see erroneous undo events at the end of fast recovery or
RTO recovery episodes. The erroneous undo events could cause those
connections to suffer repeated loss recovery episodes and high
retransmit rates.
The problem was an interaction between the non-SACK behavior on these
connections and the undo logic. The problem is that, for non-SACK
connections at the end of a loss recovery episode, if snd_una ==
high_seq, then tcp_is_non_sack_preventing_reopen() holds steady in
CA_Recovery or CA_Loss, but clears tp->retrans_stamp to 0. Then upon
the next ACK the "tcp: fix to allow timestamp undo if no retransmits
were sent" logic saw the tp->retrans_stamp at 0 and erroneously
concluded that no data was retransmitted, and erroneously performed an
undo of the cwnd reduction, restoring cwnd immediately to the value it
had before loss recovery. This caused an immediate burst of traffic
and build-up of queues and likely another immediate loss recovery
episode.
This commit fixes tcp_packet_delayed() to ignore zero retrans_stamp
values for non-SACK connections when snd_una is at or above high_seq,
because tcp_is_non_sack_preventing_reopen() clears retrans_stamp in
this case, so it's not a valid signal that we can undo.
Note that the commit named in the Fixes footer restored long-present
behavior from roughly 2005-2019, so apparently this bug was present
for a while during that era, and this was simply not caught.

wifi: iwlwifi: Fix incorrect logic on cmd_ver range checking
The current cmd_ver range checking on cmd_ver < 1 && cmd_ver > 3 can
never be true because the logical operator && is being used, cmd_ver
can never be less than 1 and also greater than 3. Fix this by using
the logical || operator.
Apparently I accidentally removed this setting in my transport
configuration rework, leading to an endless stream of warnings
from the PCIe code when relevant notifications are received by
the driver from firmware. Restore it.
