The error message buffer overflow 'dc->links' 12 <= 12 suggests that the
code is trying to access an element of the dc->links array that is
beyond its bounds. In C, arrays are zero-indexed, so an array with 12
elements has valid indices from 0 to 11. Trying to access dc->links[12]
would be an attempt to access the 13th element of a 12-element array,
which is a buffer overflow.
To fix this, ensure that the loop does not go beyond the last valid
index when accessing dc->links[i + 1] by subtracting 1 from the loop
condition.
This would ensure that i + 1 is always a valid index in the array.
Fixes the below:

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().

In (e)poll mode, threads often depend on I/O events to determine when
data is ready for consumption. Within binder, a thread may initiate a
command via BINDER_WRITE_READ without a read buffer and then make use
of epoll_wait() or similar to consume any responses afterwards.
It is then crucial that epoll threads are signaled via wakeup when they
queue their own work. Otherwise, they risk waiting indefinitely for an
event leaving their work unhandled. What is worse, subsequent commands
won't trigger a wakeup either as the thread has pending work.

commit c7aab4f170 ("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 eventfs_find_events() code tries to walk up the tree to find the
event directory that a dentry belongs to, in order to then find the
eventfs inode that is associated with that event directory.
However, it uses an odd combination of walking the dentry parent,
looking up the eventfs inode associated with that, and then looking up
the dentry from there. Repeat.
But the code shouldn't have back-pointers to dentries in the first
place, and it should just walk the dentry parenthood chain directly.
Similarly, 'set_top_events_ownership()' looks up the dentry from the
eventfs inode, but the only reason it wants a dentry is to look up the
superblock in order to look up the root dentry.
But it already has the real filesystem inode, which has that same
superblock pointer. So just pass in the superblock pointer using the
information that's already there, instead of looking up extraneous data
that is irrelevant.

The return type for ring_buffer_poll_wait() is __poll_t. This is behind
the scenes an unsigned where we can set event bits. In case of a
non-allocated CPU, we do return instead -EINVAL (0xffffffea). Lucky us,
this ends up setting few error bits (EPOLLERR | EPOLLHUP | EPOLLNVAL), so
user-space at least is aware something went wrong.
Nonetheless, this is an incorrect code. Replace that -EINVAL with a
proper EPOLLERR to clean that output. As this doesn't change the
behaviour, there's no need to treat this change as a bug fix.

syzbot has found a type mismatch between a USB pipe and the transfer
endpoint, which is triggered by the bcm5974 driver[1].
This driver expects the device to provide input interrupt endpoints and
if that is not the case, the driver registration should terminate.
Repros are available to reproduce this issue with a certain setup for
the dummy_hcd, leading to an interrupt/bulk mismatch which is caught in
the USB core after calling usb_submit_urb() with the following message:
"BOGUS urb xfer, pipe 1 != type 3"
Some other device drivers (like the appletouch driver bcm5974 is mainly
based on) provide some checking mechanism to make sure that an IN
interrupt endpoint is available. In this particular case the endpoint
addresses are provided by a config table, so the checking can be
targeted to the provided endpoints.
Add some basic checking to guarantee that the endpoints available match
the expected type for both the trackpad and button endpoints.
This issue was only found for the trackpad endpoint, but the checking
has been added to the button endpoint as well for the same reasons.
Given that there was never a check for the endpoint type, this bug has
been there since the first implementation of the driver (f89bd95c5c).

Geert Uytterhoeven reported that commit 4e244c10ea ("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,

When using hotplug and bringing up a 32-bit CPU, ask the firmware about the
BTLB information to set up the static (block) TLB entries.
For that write access to the static btlb_info struct is needed, but
since it is marked __ro_after_init the kernel segfaults with missing
write permissions.
Fix the crash by dropping the __ro_after_init annotation.

ASMedia have confirmed that all ASM106x parts currently listed in
ahci_pci_tbl[] suffer from the 43-bit DMA address limitation that we ran
into on the ASM1061, and therefore, we need to apply the quirk added by
commit 20730e9b27 ("ahci: add 43-bit DMA address quirk for ASMedia
ASM1061 controllers") to the other supported ASM106x parts as well.

Follow the docs at Documentation/bpf/kfuncs.rst:
- declare the function with `__bpf_kfunc`
- disables missing prototype warnings, which allows to remove them from
include/linux/hid-bpf.h
Removing the prototypes is not an issue because we currently have to
redeclare them when writing the BPF program. They will eventually be
generated by bpftool directly AFAIU.

Pull erofs fixes from Gao Xiang:
- fix an infinite loop issue of sub-page compressed data support found
with lengthy stress tests on a 64k-page arm64 VM
- optimize the temporary buffer allocation for low-memory scenarios,
which can reduce 20.21% on average under a heavy multi-app launch
benchmark workload
- get rid of unnecessary GFP_NOFS

When port function state change is requested, and when the driver
does not support it, it refers to the hw address attribute instead
of state attribute. Seems like a copy paste error.
Fix it by referring to the port function state attribute.
