====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for net:
1) Fix missing overflow use refcount checks in nf_tables.
2) Do not set IPS_ASSURED for IPS_NAT_CLASH entries in GRE tracker,
from Florian Westphal.
3) Bail out if nf_ct_helper_hash is NULL before registering helper,
from Florent Revest.
4) Use siphash() instead siphash_4u64() to fix performance regression,
also from Florian.
5) Do not allow to add rules to removed chains via ID,
from Thadeu Lima de Souza Cascardo.
6) Fix oob read access in byteorder expression, also from Thadeu.

If we boot with mvneta.txq_number=1, the txq_map is set incorrectly:
MVNETA_CPU_TXQ_ACCESS(1) refers to TX queue 1, but only TX queue 0 is
initialized. Fix this.

When evaluating byteorder expressions with size 2, a union with 32-bit and
16-bit members is used. Since the 16-bit members are aligned to 32-bit,
the array accesses will be out-of-bounds.
It may lead to a stack-out-of-bounds access like the one below:

Pull f2fs updates from Jaegeuk Kim:
"In this cycle, we've mainly investigated the zoned block device
support along with patches such as correcting write pointers between
f2fs and storage, adding asynchronous zone reset flow, and managing
the number of open zones.
Other than them, f2fs adds another mount option, "errors=x" to specify
how to handle when it detects an unexpected behavior at runtime.
Enhancements:
- support 'errors=remount-ro|continue|panic' mount option
- enforce some inode flag policies
- allow .tmp compression given extensions
- add some ioctls to manage the f2fs compression
- improve looped node chain flow
- avoid issuing small-sized discard commands during checkpoint
- implement an asynchronous zone reset
Bug fixes:
- fix deadlock in xattr and inode page lock
- fix and add sanity check in some error paths
- fix to avoid NULL pointer dereference f2fs_write_end_io() along
with put_super
- set proper flags to quota files
- fix potential deadlock due to unpaired node_write lock use
- fix over-estimating free section during FG GC
- fix the wrong condition to determine atomic context
As usual, also there are a number of patches with code refactoring and
minor clean-ups"

When moving devices from one namespace to another, mc addresses are
cleaned in software while not removed from application firmware. Thus
the mc addresses are remained and will cause resource leak.
Now use `__dev_mc_unsync` to clean mc addresses when closing port.

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.

Originally this used jhash2() over tuple and folded the zone id,
the pernet hash value, destination port and l4 protocol number into the
32bit seed value.
When the switch to siphash was done, I used an on-stack temporary
buffer to build a suitable key to be hashed via siphash().
But this showed up as performance regression, so I got rid of
the temporary copy and collected to-be-hashed data in 4 u64 variables.
This makes it easy to build tuples that produce the same hash, which isn't
desirable even though chain lengths are limited.
Switch back to plain siphash, but just like with jhash2(), take advantage
of the fact that most of to-be-hashed data is already in a suitable order.
Use an empty struct as annotation in 'struct nf_conntrack_tuple' to mark
last member that can be used as hash input.
The only remaining data that isn't present in the tuple structure are the
zone identifier and the pernet hash: fold those into the key.

If nf_conntrack_init_start() fails (for example due to a
register_nf_conntrack_bpf() failure), the nf_conntrack_helper_fini()
clean-up path frees the nf_ct_helper_hash map.
When built with NF_CONNTRACK=y, further netfilter modules (e.g:
netfilter_conntrack_ftp) can still be loaded and call
nf_conntrack_helpers_register(), independently of whether nf_conntrack
initialized correctly. This accesses the nf_ct_helper_hash dangling
pointer and causes a uaf, possibly leading to random memory corruption.
This patch guards nf_conntrack_helper_register() from accessing a freed
or uninitialized nf_ct_helper_hash pointer and fixes possible
uses-after-free when loading a conntrack module.

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
results from LKFT.

When an error was detected when checking the marks, a message was
correctly printed mentioning the error but followed by another one
saying everything was OK and the selftest was not marked as failed as
expected.
Now the 'ret' variable is directly set to 1 in order to make sure the
exit is done with an error, similar to what is done in other functions.
While at it, the error is correctly propagated to the caller.

In case of "external" errors when preparing the environment for the
TProxy tests, the subtests were marked as skipped.
This is fine but it means these errors are ignored. On MPTCP Public CI,
we do want to catch such issues and mark the selftest as failed if there
are such issues. We can then use mptcp_lib_fail_if_expected_feature()

Since the blamed commit, closing the first subflow resets the first
subflow socket state to SS_UNCONNECTED.
The current mptcp listen implementation relies only on such
state to prevent touching not-fully-disconnected sockets.
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
subflow socket state update into mptcp_disconnect(), but in the long
term the first subflow socket should be removed: better avoid relaying
on it for internal consistency check.

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.

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:
https://lore.kernel.org/netdev/f494387c8d55d9b1d5a3e88beedeeb448f2e6cc3.camel@redhat.com/

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).

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.

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 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.

Vegard Nossum pointed out two different problems with the error handling
in init_module_from_file():
(a) the idempotent loading code didn't clean up properly in some error
cases, leaving the on-stack 'struct idempotent' element still in
the hash table
(b) failure to read the module file would nonsensically update the
'invalid_kread_bytes' stat counter with the error value
The first error is quite nasty, in that it can then cause subsequent
idempotent loads of that same file to access stale stack contents of the
previous failure. The case may not happen in any normal situation
(explaining all the "Tested-by's on the original change), and requires
admin privileges, but syzkaller triggers random bad behavior as a
result:
BUG: soft lockup in sys_finit_module
BUG: unable to handle kernel paging request in init_module_from_file
general protection fault in init_module_from_file
INFO: task hung in init_module_from_file
KASAN: out-of-bounds Read in init_module_from_file
KASAN: slab-out-of-bounds Read in init_module_from_file
...
The second error is fairly benign and just leads to nonsensical stats
(and has been around since the debug stats were added).
Vegard also provided a patch for the idempotent loading issue, but I'd
rather re-organize the code and make it more legible using another level
of helper functions than add the usual "goto out" error handling.

Merge CPU power management updates for 6.5-rc1:
- Add missing __init annotation to one function in the intel_idle
drvier (Rafael Wysocki).
- Make intel_pstate use a correct scaling factor when mapping HWP
performance levels to frequency values on hybrid-capable systems
with disabled E-cores (Srinivas Pandruvada).
- Fix Kconfig dependencies of the cpufreq-dt-platform driver (Viresh
Kumar).
- Add support to build cpufreq-dt-platdev as a module (Zhipeng Wang).
- Don't allocate Sparc's cpufreq_driver dynamically (Viresh Kumar).
- Add support for TI's AM62A7 platform (Vibhore Vardhan).
- Add support for Armada's ap807 platform (Russell King (Oracle)).
- Add support for StarFive JH7110 SoC (Mason Huo).
- Fix voltage selection for Mediatek Socs (Daniel Golle).
- Fix error handling in Tegra's cpufreq driver (Christophe JAILLET).
- Document Qualcomm's IPQ8074 in DT bindings (Robert Marko).
- Don't warn for disabling a non-existing frequency for imx6q cpufreq
driver (Christoph Niedermaier).
- Use dev_err_probe() in Qualcomm's cpufreq driver (Andrew Halaney).
