commit a48491c65b513e5cdc3e7a886a4db915f848a5f5 upstream.
It looks like the C15B laptop got another vendor: ByteSpeed LLC.
Avoid AUX loopback on this touchpad as well, thus input subsystem will
be able to recognize a Synaptics touchpad in the AUX port.

[ Upstream commit 4d521943f76bd0d1e68ea5e02df7aadd30b2838a ]
GPIO_ACTIVE_x flags are not correct in the context of interrupt flags.
These are simple defines so they could be used in DTS but they will not
have the same meaning:
1. GPIO_ACTIVE_HIGH = 0 = IRQ_TYPE_NONE
2. GPIO_ACTIVE_LOW = 1 = IRQ_TYPE_EDGE_RISING
Correct the interrupt flags, assuming the author of the code wanted same
logical behavior behind the name "ACTIVE_xxx", this is:
ACTIVE_LOW => IRQ_TYPE_LEVEL_LOW
ACTIVE_HIGH => IRQ_TYPE_LEVEL_HIGH

[ Upstream commit 6ee50c8e262a0f0693dad264c3c99e30e6442a56 ]
The .x25_addr[] address comes from the user and is not necessarily
NUL terminated. This leads to a couple problems. The first problem is
that the strlen() in x25_bind() can read beyond the end of the buffer.
The second problem is more subtle and could result in memory corruption.
The call tree is:
x25_connect()
--> x25_write_internal()
--> x25_addr_aton()
The .x25_addr[] buffers are copied to the "addresses" buffer from
x25_write_internal() so it will lead to stack corruption.
Verify that the strings are NUL terminated and return -EINVAL if they
are not.

[ Upstream commit 44f64f23bae2f0fad25503bc7ab86cd08d04cd47 ]
Netfilter changes PACKET_OTHERHOST to PACKET_HOST before invoking the
hooks as, while it's an expected value for a bridge, routing expects
PACKET_HOST. The change is undone later on after hook traversal. This
can be seen with pairs of functions updating skb>pkt_type and then
reverting it to its original value:
For hook NF_INET_PRE_ROUTING:
setup_pre_routing / br_nf_pre_routing_finish
For hook NF_INET_FORWARD:
br_nf_forward_ip / br_nf_forward_finish
But the third case where netfilter does this, for hook
NF_INET_POST_ROUTING, the packet type is changed in br_nf_post_routing
but never reverted. A comment says:
/* We assume any code from br_dev_queue_push_xmit onwards doesn't care
* about the value of skb->pkt_type. */
But when having a tunnel (say vxlan) attached to a bridge we have the
following call trace:
br_nf_pre_routing
br_nf_pre_routing_ipv6
br_nf_pre_routing_finish
br_nf_forward_ip
br_nf_forward_finish
br_nf_post_routing <- pkt_type is updated to PACKET_HOST
br_nf_dev_queue_xmit <- but not reverted to its original value
vxlan_xmit
vxlan_xmit_one
skb_tunnel_check_pmtu <- a check on pkt_type is performed
In this specific case, this creates issues such as when an ICMPv6 PTB
should be sent back. When CONFIG_BRIDGE_NETFILTER is enabled, the PTB
isn't sent (as skb_tunnel_check_pmtu checks if pkt_type is PACKET_HOST
and returns early).
If the comment is right and no one cares about the value of
skb->pkt_type after br_dev_queue_push_xmit (which isn't true), resetting
it to its original value should be safe.

This is a potential use-after-free if the sysfs nodes are being accessed
whilst removing the struct slave, so wait for the object destruction to
complete before freeing the struct slave itself.

[ Upstream commit f33d9e2b48a34e1558b67a473a1fc1d6e793f93c ]
Starting with iOS 14 released in September 2020, connectivity using the
personal hotspot USB tethering function of iOS devices is broken.
Communication between the host and the device (for example ICMP traffic
or DNS resolution using the DNS service running in the device itself)
works fine, but communication to endpoints further away doesn't work.
Investigation on the matter shows that no UDP and ICMP traffic from the
tethered host is reaching the Internet at all. For TCP traffic there are
exchanges between tethered host and server but packets are modified in
transit leading to impossible communication.
After some trials Matti Vuorela discovered that reducing the URB buffer
size by two bytes restored the previous behavior. While a better
solution might exist to fix the issue, since the protocol is not
publicly documented and considering the small size of the fix, let's do
that.

[ Upstream commit 3b3fd068c56e3fbea30090859216a368398e39bf ]
rose_send_frame() dereferences `neigh->dev` when called from
rose_transmit_clear_request(), and the first occurrence of the
`neigh` is in rose_loopback_timer() as `rose_loopback_neigh`,
and it is initialized in rose_add_loopback_neigh() as NULL.
i.e when `rose_loopback_neigh` used in rose_loopback_timer()
its `->dev` was still NULL and rose_loopback_timer() was calling
rose_rx_call_request() without checking for NULL.
- net/rose/rose_link.c
This bug seems to get triggered in this line:
rose_call = (ax25_address *)neigh->dev->dev_addr;
Fix it by adding NULL checking for `rose_loopback_neigh->dev`
in rose_loopback_timer().

[ Upstream commit c5dab0941fcdc9664eb0ec0d4d51433216d91336 ]
Child sockets erroneously inherit their parent's sk_type (ie. SOCK_*),
instead of the PF_IUCV protocol that the parent was created with in
iucv_sock_create().
We're currently not using sk->sk_protocol ourselves, so this shouldn't
have much impact (except eg. getting the output in skb_dump() right).

The Joy-Cons each create their own, independent input devices, so it is
up to userspace to combine them if desired.

Map the permission gating RTM_GETLINK messages to a new permission so
that it can be distinguished from the other netlink route permissions
in selinux policy.
This is a temporary Android-only patch that will be deprecated in
newer kernels once the long-term solution lands as discusssed on the
mailing list [1]. The maintainer's recommended solution is more
general, much more complex, and likely not suitable for backporting.
This patch provides the minimal change needed for Android including
the userspace settable trigger which ensures that the permission
change is only applied to the newest version of Android which
contains the changes needed for userpace compatibility.

There is a possibility of sharing process_private between two unrelated
processes due to PID wrapping. In kgsl_process_private_new(), instead
of checking numeric TGID, compare the unique pid pointer of the current
process with that of the existing processes in kgsl process list to
allow sharing of process_private data judiciously. Also, in all required
functions get TGID/PID of a process from its struct pid.

When releasing a thread todo list when tearing down
a binder_proc, the following race was possible which
could result in a use-after-free:
1. Thread 1: enter binder_release_work from binder_thread_release
2. Thread 2: binder_update_ref_for_handle() calls binder_dec_node_ilocked()
3. Thread 2: dec nodeA --> 0 (will free node)
4. Thread 1: ACQ inner_proc_lock
5. Thread 2: block on inner_proc_lock
6. Thread 1: dequeue work (BINDER_WORK_NODE, part of nodeA)
7. Thread 1: REL inner_proc_lock
8. Thread 2: ACQ inner_proc_lock
9. Thread 2: todo list cleanup, but work was already dequeued
10. Thread 2: free node
11. Thread 2: REL inner_proc_lock
12. Thread 1: deref w->type (UAF)
The problem was that for a BINDER_WORK_NODE, the binder_work element
must not be accessed after releasing the inner_proc_lock while
processing the todo list elements since another thread might be
handling a deref on the node containing the binder_work element
leading to the node being freed.

Currently if the controller receives a standard interface request
like 0x81 it goes to ep0_inspect_setup where on the basis of
bRequestType it calls ep0_std_request which calls handle_status.
Since it is an interface request, it will further call
delegate_request which is handles in composite_setup and calls
ep0_queue. However, in the implementation of handle_status we have
an if check for return value of delegate request. If it returns
zero then instead of bailing out from there we break from the switch
and go to the return statement of handle_status, which is ep0_queue.
This results in queuing the same request two times resulting in a
list corruption due to double add.
Fix this by returning from handle_status irrespective of the
return status as in case ep0_queue fails we are suppose to
bail out without doing anything.
