- Fix bad git merge of #endif in arm64 code
A merge of the arm64 tree caused #endif to go into the wrong place
- Fix crash on lseek of write access to tracefs/error_log
Opening error_log as write only, and then doing an lseek() causes a
kernel panic, because the lseek() handle expects a "seq_file" to
exist (which is not done on write only opens). Use tracing_lseek()
that tests for this instead of calling the default seq lseek handler.
- Check for negative instead of -E2BIG for error on strscpy() returns
Instead of testing for -E2BIG from strscpy(), to be more robust,
check for less than zero, which will make sure it catches any error
that strscpy() may someday return.

i2c: xiic: Don't try to handle more interrupt events after error
In xiic_process, it is possible that error events such as arbitration
lost or TX error can be raised in conjunction with other interrupt flags
such as TX FIFO empty or bus not busy. Error events result in the
controller being reset and the error returned to the calling request,
but the function could potentially try to keep handling the other
events, such as by writing more messages into the TX FIFO. Since the
transaction has already failed, this is not helpful and will just cause
issues.
This problem has been present ever since:
commit
7f9906bd7f72 ("i2c: xiic: Service all interrupts in isr")
which allowed non-error events to be handled after errors, but became
more obvious after:
commit
743e227a8959 ("i2c: xiic: Defer xiic_wakeup() and
__xiic_start_xfer() in xiic_process()")
which reworked the code to add a WARN_ON which triggers if both the
xfer_more and wakeup_req flags were set, since this combination is
not supposed to happen, but was occurring in this scenario.
Skip further interrupt handling after error flags are detected to avoid
this problem.

ALSA: jack: Fix mutex call in snd_jack_report()
snd_jack_report() is supposed to be callable from an IRQ context, too,
and it's indeed used in that way from virtsnd driver. The fix for
input_dev race in commit
1b6a6fc5280e ("ALSA: jack: Access input_dev
under mutex"), however, introduced a mutex lock in snd_jack_report(),
and this resulted in a potential sleep-in-atomic.
For addressing that problem, this patch changes the relevant code to
use the object get/put and removes the mutex usage. That is,
snd_jack_report(), it takes input_get_device() and leaves with
input_put_device() for assuring the input_dev being assigned.
Although the whole mutex could be reduced, we keep it because it can
be still a protection for potential races between creation and
deletion.

perf test: Fix event parsing test on Arm
The test looks for a PMU from sysfs with type = PERF_TYPE_RAW when
opening a raw event. Arm doesn't have a real raw PMU, only core PMUs
with unique types other than raw.
Instead of looking for a matching PMU, just test that the event type
was parsed as raw and skip the PMU search on Arm. The raw event type
test should also apply to all platforms so add it outside of the ifdef.

gup: make the stack expansion warning a bit more targeted
I added a warning about about GUP no longer expanding the stack in
commit
a425ac5365f6 ("gup: add warning if some caller would seem to want
stack expansion"), but didn't really expect anybody to hit it.
And it's true that nobody seems to have hit a _real_ case yet, but we
certainly have a number of reports of false positives. Which not only
causes extra noise in itself, but might also end up hiding any real
cases if they do exist.
So let's tighten up the warning condition, and replace the simplistic
vma = find_vma(mm, start);
if (vma && (start < vma->vm_start)) {
WARN_ON_ONCE(vma->vm_flags & VM_GROWSDOWN);
with a
vma = gup_vma_lookup(mm, start);
helper function which works otherwise like just "vma_lookup()", but with
some heuristics for when to warn about gup no longer causing stack
expansion.
In particular, don't just warn for "below the stack", but warn if it's
_just_ below the stack (with "just below" arbitrarily defined as 64kB,
because why not?). And rate-limit it to at most once per hour, which
means that any false positives shouldn't completely hide subsequent
reports, but we won't be flooding the logs about it either.
The previous code triggered when some GUP user (chromium crashpad)
accessing past the end of the previous vma, for example. That has never
expanded the stack, it just causes GUP to return early, and as such we
shouldn't be warning about it.
This is still going trigger the randomized testers, but to mitigate the
noise from that, use "dump_stack()" instead of "WARN_ON_ONCE()" to get
the kernel call chain. We'll get the relevant information, but syzbot
shouldn't get too upset about it.
Also, don't even bother with the GROWSUP case, which would be using
different heuristics entirely, but only happens on parisc.

mm: riscv: fix an unsafe pte read in huge_pte_alloc()
The WARN_ON_ONCE() statement in riscv's huge_pte_alloc() is susceptible
to false positives, because the pte is read twice at the C language
level, locklessly, within the same conditional statement. Depending on
compiler behavior, this can lead to generated machine code that actually
reads the pte just once, or twice. Reading twice will expose the code to
changing pte values and cause incorrect behavior.
In [1], similar code actually caused a kernel crash on 64-bit x86, when
using clang to build the kernel, but only after the conversion from *pte
reads, to ptep_get(pte). The latter uses READ_ONCE(), which forced a
double read of *pte.
Rather than waiting for the upcoming ptep_get() conversion, just convert
this part of the code now, but in a way that avoids the above problem:
take a single snapshot of the pte before using it in the WARN
conditional.
As expected, this preparatory step does not actually change the
generated code ("make mm/hugetlbpage.s"), on riscv64, when using a gcc
12.2 cross compiler.

ISA etc had yet to be ratified. By the ratification of the base ISA,
incompatible changes had snuck into the specifications - for example the
Zicsr and Zifencei extensions were spun out of the base ISA.
Fast forward to today, and the reason for this patch.
Currently the riscv,isa dt property permits only a specific subset of
the ISA string - in particular it excludes version numbering.
With the current constraints, it is not possible to discern whether
"rv64i" means that the hart supports the fence.i instruction, for
example.
Future systems may choose to implement their own instruction fencing,
perhaps using a vendor extension, or they may not implement the optional
counter extensions. Software needs a way to determine this.
versioning schemes
==================
"Use the extension versions that are described in the ISA manual" you
may say, and it's not like this has not been considered.
Firstly, software that parses the riscv,isa property at runtime will
need to contain a lookup table of some sort that maps arbitrary versions
to versions it understands. There is not a consistent application of
version number applied to extensions, with a higgledy-piggledy
collection of tags, "bare" and versioned documents awaiting the reader
on the "recently ratified extensions" page:
https://wiki.riscv.org/display/HOME/Recently+Ratified+Extensions
As an aside, and this is reflected in the patch too, since many
extensions have yet to appear in a release of the ISA specs,
they are defined by commits in their respective "working draft"
repositories.
Secondly, there is an issue of backwards compatibility, whereby allowing
numbers in the ISA string, some parsers may be broken. This would
require an additional property to be created to even use the versions in
this manner.
~boolean properties~ string array property
==========================================
If a new property is needed, the whole approach may as well be looked at
from the bottom up. A string with limited character choices etc is
hardly the best approach for communicating extension information to
software.
Switching to using properties that are defined on a per extension basis,
allows us to define explicit meanings for the DT representation of each
extension - rather than the current situation where different operating
systems or other bits of software may impart different meanings to
characters in the string.
Clearly the best source of meanings is the specifications themselves,
this just provides us the ability to choose at what point in time the
meaning is set. If an extension changes incompatibility in the future,
a new property will be required.
Off-list, some of the RVI folks have committed to shoring up the wording
in either the ISA specifications, the riscv-isa-manual or
so that in the future, modifications to and additions or removals of
features will require a new extension. Codifying that assertion
somewhere would make it quite unlikely that compatibility would be
broken, but we have the tools required to deal with it, if & when it
crops up.
It is in our collective interest, as consumers of extension meanings, to
define a scheme that enforces compatibility.
The use of individual elements, rather than a single string, will also
permit validation that the properties have a meaning, as well as
potentially reject mutually exclusive combinations, or enforce
dependencies between extensions. That would not have be possible with
the current dt-schema infrastructure for arbitrary strings, as we would
need to add a riscv,isa parser to dt-validate!
That's not implemented in this patch, but rather left as future work (for
the brave, or the foolish).
parser simplicity
=================
Many systems that parse DT at runtime already implement an function that
can check for the presence of a string in an array of string, as it is
similar to the process for parsing a list of compatible strings, so a
bunch of new, custom, DT parsing should not be needed.
Getting rid of "riscv,isa" parsing would be a nice simplification, but
unfortunately for backwards compatibility with old dtbs, existing
parsers may not be removable - which may greatly simplify
dt parsing code. In Linux, for example, checking for whether a hart
supports an extension becomes as simple as:
of_property_match_string(node, "riscv,isa-extensions", "zicbom")
vendor extensions
=================
Compared to riscv,isa, this proposed scheme promotes vendor extensions,
oft touted as the strength of RISC-V, to first-class citizens.
At present, extensions are defined as meaning what the RISC-V ISA
specifications say they do. There is no realistic way of using that
interface to provide cross-platform definitions for what vendor
extensions mean. Vendor extensions may also have even less consistency
than RVI do in terms of versioning, or no care about backwards
compatibility.
The new property allows us to assign explicit meanings on a per vendor
extension basis, backed up by a description of their meanings.
fin
===
Create a new file to store the extension meanings and a new
riscv,isa-base property to replace the aspect of riscv,isa that is
not represented by the new property - the base ISA implemented by a hart.
As a starting point, add properties for extensions currently used in
Linux.
Finally, mark riscv,isa as deprecated, as removing support for it in
existing programs would be an ABI break.

====================
mptcp: fixes for v6.5
Here is a first batch of fixes for v6.5 and older.
The fixes are not linked to each others.
Patch 1 ensures subflows are unhashed before cleaning the backlog to
avoid races. This fixes another recent fix from v6.4.
Patch 2 does not rely on implicit state check in mptcp_listen() to avoid
races when receiving an MP_FASTCLOSE. A regression from v5.17.
The rest fixes issues in the selftests.
Patch 3 makes sure errors when setting up the environment are no longer
ignored. For v5.17+.
Patch 4 uses 'iptables-legacy' if available to be able to run on older
kernels. A fix for v5.13 and newer.
Patch 5 catches errors when issues are detected with packet marks. Also
for v5.13+.
Patch 6 uses the correct variable instead of an undefined one. Even if
there was no visible impact, it can help to find regressions later. An
issue visible in v5.19+.
Patch 7 makes sure errors with some sub-tests are reported to have the
selftest marked as failed as expected. Also for v5.19+.
Patch 8 adds a kernel config that is required to execute MPTCP
selftests. It is valid for v5.9+.
Patch 9 fixes issues when validating the userspace path-manager with
32-bit arch, an issue affecting v5.19+.

When using pm_nl_ctl to validate userspace path-manager's behaviours, it
was failing on 32-bit architectures ~half of the time.
pm_nl_ctl was not reporting any error but the command was not doing what
it was expected to do. As a result, the expected linked event was not
triggered after and the test failed.
This is due to the fact the token given in argument to the application
was parsed as an integer with atoi(): in a 32-bit arch, if the number
was bigger than INT_MAX,
2147483647 was used instead.
This can simply be fixed by using strtoul() instead of atoi().
The errors have been seen "by chance" when manually looking at the

Since the blamed commit, closing the first subflow resets the first

The current mptcp listen implementation relies only on such

Incoming mptcp fastclose (or paired endpoint removal) unconditionally
closes the first subflow.
All the above allows an incoming fastclose followed by a listen() call
to successfully race with a blocking recvmsg(), potentially causing the
latter to hit a divide by zero bug in cleanup_rbuf/__tcp_select_window().
Address the issue explicitly checking the msk socket state in
mptcp_listen(). An alternative solution would be moving the first

afs: Fix accidental truncation when storing data
When an AFS FS.StoreData RPC call is made, amongst other things it is
given the resultant file size to be. On the server, this is processed
by truncating the file to new size and then writing the data.
Now, kafs has a lock (vnode->io_lock) that serves to serialise
operations against a specific vnode (ie. inode), but the parameters for
the op are set before the lock is taken. This allows two writebacks
(say sync and kswapd) to race - and if writes are ongoing the writeback
for a later write could occur before the writeback for an earlier one if
the latter gets interrupted.
Note that afs_writepages() cannot take i_mutex and only takes a shared
lock on vnode->validate_lock.
Also note that the server does the truncation and the write inside a
lock, so there's no problem at that end.
Fix this by moving the calculation for the proposed new i_size inside
the vnode->io_lock. Also reset the iterator (which we might have read
from) and update the mtime setting there.

octeontx-af: fix hardware timestamp configuration
MAC block on CN10K (RPM) supports hardware timestamp configuration. The
previous patch which added timestamp configuration support has a bug.
Though the netdev driver requests to disable timestamp configuration,
the driver is always enabling it.
This patch fixes the same.

====================
dsa: Fix mangled link-local MAC DAs with SJA1105 DSA
The SJA1105 hardware tagging protocol is weird and will put DSA
information (source port, switch ID) in the MAC DA of the packets sent
to the CPU, and then send some additional (meta) packets which contain
the original bytes from the previous packet's MAC DA.
The tagging protocol driver contains logic to handle this, but the meta
frames are optional functionality, and there are configurations when
they aren't received (no PTP RX timestamping). Thus, the MAC DA from
packets sent to the stack is not correct in all cases.
Also, during testing it was found that the MAC DA patching procedure was
incorrect.
The investigation comes as a result of this discussion with Paolo:

net: dsa: sja1105: always enable the send_meta options
incl_srcpt has the limitation, mentioned in commit
b4638af8885a ("net:
dsa: sja1105: always enable the INCL_SRCPT option"), that frames with a
MAC DA of 01:80:c2:xx:yy:zz will be received as 01:80:c2:00:00:zz unless
PTP RX timestamping is enabled.
The incl_srcpt option was initially unconditionally enabled, then that
changed with commit
42824463d38d ("net: dsa: sja1105: Limit use of
incl_srcpt to bridge+vlan mode"), then again with
b4638af8885a ("net:
dsa: sja1105: always enable the INCL_SRCPT option"). Bottom line is that
it now needs to be always enabled, otherwise the driver does not have a
reliable source of information regarding source_port and switch_id for
link-local traffic (tag_8021q VLANs may be imprecise since now they
identify an entire bridging domain when ports are not standalone).
If we accept that PTP RX timestamping (and therefore, meta frame
generation) is always enabled in hardware, then that limitation could be
avoided and packets with any MAC DA can be properly received, because
meta frames do contain the original bytes from the MAC DA of their
associated link-local packet.
This change enables meta frame generation unconditionally, which also
has the nice side effects of simplifying the switch control path
(a switch reset is no longer required on hwtstamping settings change)
and the tagger data path (it no longer needs to be informed whether to
expect meta frames or not - it always does).

net: dsa: tag_sja1105: fix MAC DA patching from meta frames
The SJA1105 manual says that at offset 4 into the meta frame payload we
have "MAC destination byte 2" and at offset 5 we have "MAC destination
byte 1". These are counted from the LSB, so byte 1 is h_dest[ETH_HLEN-2]
aka h_dest[4] and byte 2 is h_dest[ETH_HLEN-3] aka h_dest[3].
The sja1105_meta_unpack() function decodes these the other way around,
so a frame with MAC DA 01:80:c2:11:22:33 is received by the network
stack as having 01:80:c2:22:11:33.

net: Replace strlcpy with strscpy
strlcpy() reads the entire source buffer first.
This read may exceed the destination size limit.
This is both inefficient and can lead to linear read
overflows if a source string is not NUL-terminated [1].
In an effort to remove strlcpy() completely [2], replace
strlcpy() here with strscpy().
No return values were used, so direct replacement is safe.

pptp: Fix fib lookup calls.
PPTP uses pppox sockets (struct pppox_sock). These sockets don't embed
an inet_sock structure, so it's invalid to call inet_sk() on them.
Therefore, the ip_route_output_ports() call in pptp_connect() has two
problems:
* The tos variable is set with RT_CONN_FLAGS(sk), which calls
inet_sk() on the pppox socket.
* ip_route_output_ports() tries to retrieve routing flags using
inet_sk_flowi_flags(), which is also going to call inet_sk() on the
pppox socket.
While PPTP doesn't use inet sockets, it's actually really layered on
top of IP and therefore needs a proper way to do fib lookups. So let's
define pptp_route_output() to get a struct rtable from a pptp socket.
Let's also replace the ip_route_output_ports() call of pptp_xmit() for
consistency.
In practice, this means that:
* pptp_connect() sets ->flowi4_tos and ->flowi4_flags to zero instead
of using bits of unrelated struct pppox_sock fields.
* pptp_xmit() now respects ->sk_mark and ->sk_uid.
* pptp_xmit() now calls the security_sk_classify_flow() security
hook, thus allowing to set ->flowic_secid.
* pptp_xmit() now passes the pppox socket to xfrm_lookup_route().
Found by code inspection.
