It is one use-after-free in ip_check_mc_rcu.
In ip_mc_del_src, the ip_sf_list of pmc has been freed under pmc->lock protection.
But access to ip_sf_list in ip_check_mc_rcu is not protected by the lock.

75faeb6920 UPSTREAM: net/packet: rx_owner_map depends on pg_vec
[ Upstream commit ec6af094ea28f0f2dda1a6a33b14cd57e36a9755 ]

Packet sockets may switch ring versions. Avoid misinterpreting state
between versions, whose fields share a union. rx_owner_map is only
allocated with a packet ring (pg_vec) and both are swapped together.
If pg_vec is NULL, meaning no packet ring was allocated, then neither
was rx_owner_map. And the field may be old state from a tpacket_v3.

3f6c0a8ade sctp: add param size validation for SCTP_PARAM_SET_PRIMARY
commit ef6c8d6ccf0c1dccdda092ebe8782777cd7803c9 upstream.

When SCTP handles an INIT chunk, it calls for example:
sctp_sf_do_5_1B_init
  sctp_verify_init
    sctp_verify_param
  sctp_process_init
    sctp_process_param
      handling of SCTP_PARAM_SET_PRIMARY

sctp_verify_init() wasn't doing proper size validation and neither the
later handling, allowing it to work over the chunk itself, possibly being
uninitialized memory.

91ef606627 sctp: validate chunk size in __rcv_asconf_lookup
commit b6ffe7671b24689c09faa5675dd58f93758a97ae upstream.

In one of the fallbacks that SCTP has for identifying an association for an
incoming packet, it looks for AddIp chunk (from ASCONF) and take a peek.
Thing is, at this stage nothing was validating that the chunk actually had
enough content for that, allowing the peek to happen over uninitialized
memory.

Similar check already exists in actual asconf handling in
sctp_verify_asconf().

5dcfe92704 sctp: add size validation when walking chunks
[ Upstream commit 50619dbf8db77e98d821d615af4f634d08e22698 ]

The first chunk in a packet is ensured to be present at the beginning of
sctp_rcv(), as a packet needs to have at least 1 chunk. But the second
one, may not be completely available and ch->length can be over
uninitialized memory.

Fix here is by only trying to walk on the next chunk if there is enough to
hold at least the header, and then proceed with the ch->length validation
that is already there.

f0355ee97f sctp: validate from_addr_param return
[ Upstream commit 0c5dc070ff3d6246d22ddd931f23a6266249e3db ]

Ilja reported that, simply putting it, nothing was validating that
from_addr_param functions were operating on initialized memory. That is,
the parameter itself was being validated by sctp_walk_params, but it
doesn't check for types and their specific sizes and it could be a 0-length
one, causing from_addr_param to potentially work over the next parameter or
even uninitialized memory.

The fix here is to, in all calls to from_addr_param, check if enough space
is there for the wanted IP address type.

843227efe1 af_unix: fix garbage collect vs MSG_PEEK
commit cbcf01128d0a92e131bd09f1688fe032480b65ca upstream.

unix_gc() assumes that candidate sockets can never gain an external
reference (i.e.  be installed into an fd) while the unix_gc_lock is
held.  Except for MSG_PEEK this is guaranteed by modifying inflight
count under the unix_gc_lock.

MSG_PEEK does not touch any variable protected by unix_gc_lock (file
count is not), yet it needs to be serialized with garbage collection.
Do this by locking/unlocking unix_gc_lock:

 1) increment file count

 2) lock/unlock barrier to make sure incremented file count is visible
    to garbage collection

 3) install file into fd

This is a lock barrier (unlike smp_mb()) that ensures that garbage
collection is run completely before or completely after the barrier.

072dfad577 net: split out functions related to registering inflight socket files
commit f4e65870e5cede5ca1ec0006b6c9803994e5f7b8 upstream.

We need this functionality for the io_uring file registration, but
we cannot rely on it since CONFIG_UNIX can be modular. Move the helpers
to a separate file, that's always builtin to the kernel if CONFIG_UNIX is
m/y.

No functional changes in this patch, just moving code around.

b669e0ea2e net: qrtr: Use radix_tree_iter_delete to delete tx flow
Below two issues are handled in this change.

1.Use radix_tree_iter_delete instead of radix_tree_delete to properly
remove slots in a radix tree without any dangling references.

2.Flow entry can be deleted when sending process waiting on the queue
if remote socket closes.Which leads to accessing non-valid flow entry.
To resolve this lookup for the tx flow entry each time before reading
flow count or inserting caller process to waiting list to check the
validity of flow entry in the radix tree.

898151cd02 net: qrtr: Make wakeup timeout configurable
The qrtr driver can guarantee that the packet gets queued to the socket
but cannot guarantee the client process will get time to run if auto
sleep is enabled. This config will help mitigate missed packets on
systems where auto sleep is too aggressive.

Use the pm_wakeup_ws_event() api so a hard wakeup can be specified.
This will ensure a resume occurs if the data coming in happens while
the device is going into suspend.

6f2d57e4b1 netfilter: nf_conntrack_h323: lost .data_len definition for Q.931/ipv6
Could you please push this patch into stable@?
it fixes memory corruption in kernels  v3.5 .. v4.10

Lost .data_len definition leads to write beyond end of
struct nf_ct_h323_master. Usually it corrupts following
struct nf_conn_nat, however if nat is not loaded it corrupts
following slab object.

In mainline this problem went away in v4.11,
after commit 9f0f3ebeda ("netfilter: helpers: remove data_len usage
for inkernel helpers") however many stable kernels are still affected.

Fixes: 1afc56794e ("netfilter: nf_ct_helper: implement variable length helper private data") # v3.5

Eric Dumazet
961e9a1d2d tcp: adjust rto_base in retransmits_timed_out()
The cited commit exposed an old retransmits_timed_out() bug
which assumed it could call tcp_model_timeout() with
TCP_RTO_MIN as rto_base for all states.

But flows in SYN_SENT or SYN_RECV state uses a different
RTO base (1 sec instead of 200 ms, unless BPF choses
another value).

This caused a reduction of SYN retransmits from 6 to 4 with
the default /proc/sys/net/ipv4/tcp_syn_retries value.

8591132ecd tcp: retry more conservatively on local congestion
Previously when the sender fails to retransmit a data packet on
timeout due to congestion in the local host (e.g. throttling in
qdisc), it'll retry within an RTO up to 500ms.

In low-RTT networks such as data-centers, RTO is often far
below the default minimum 200ms (and the cap 500ms). Then local
host congestion could trigger a retry storm pouring gas to the
fire. Worse yet, the retry counter (icsk_retransmits) is not
properly updated so the aggressive retry may exceed the system
limit (15 rounds) until the packet finally slips through.

On such rare events, it's wise to retry more conservatively (500ms)
and update the stats properly to reflect these incidents and follow
the system limit. Note that this is consistent with the behavior
when a keep-alive probe is dropped due to local congestion.

2aa81b162f tcp: always set retrans_stamp on recovery
Previously TCP socket's retrans_stamp is not set if the
retransmission has failed to send. As a result if a socket is
experiencing local issues to retransmit packets, determining when
to abort a socket is complicated w/o knowning the starting time of
the recovery since retrans_stamp may remain zero.

This complication causes sub-optimal behavior that TCP may use the
latest, instead of the first, retransmission time to compute the
elapsed time of a stalling connection due to local issues. Then TCP
may disrecard TCP retries settings and keep retrying until it finally
succeed: not a good idea when the local host is already strained.

The simple fix is to always timestamp the start of a recovery.
It's worth noting that retrans_stamp is also used to compare echo
timestamp values to detect spurious recovery. This patch does
not break that because retrans_stamp is still later than when the
original packet was sent.

TCP can be fooled when ACK comes back, because the following

e786a31cce net/sched: fix race between deactivation and dequeue for NOLOCK qdisc
The test implemented by some_qdisc_is_busy() is somewhat loosy for
NOLOCK qdisc, as we may hit the following scenario :

CPU1						CPU2
// in net_tx_action()
clear_bit(__QDISC_STATE_SCHED...);
					// in some_qdisc_is_busy()
					val = (qdisc_is_running(q) ||
					     test_bit(__QDISC_STATE_SCHED,
							&q->state));
					// here val is 0 but...
qdisc_run(q)
// ... CPU1 is going to run the qdisc next

As a conseguence qdisc_run() in net_tx_action() can race with
qdisc_reset() in dev_qdisc_reset(). Such race is not possible for !NOLOCK
qdisc as both the above bit operations are under the root qdisc lock().

After commit 021a17ed79 ("pfifo_fast: drop unneeded additional lock on
dequeue") the race can cause use after free and/or null ptr dereference,
but the root cause is likely older.

This patch addresses the issue explicitly checking for deactivation under
the seqlock for NOLOCK qdisc, so that the qdisc_run() in the critical
scenario becomes a no-op.

Note that the enqueue() op can still execute concurrently with
dev_qdisc_reset(), but that is safe due to the skb_array() locking, and
we can't avoid that for NOLOCK qdiscs.

			dequeue")

108aabc2a5 ANDROID: xt_qtaguid: Remove tag_entry from process list on untag
A sock_tag_entry can only be part of one process's
pqd_entry->sock_tag_list. Retagging the socket only updates
sock_tag_entry->tag, and does not add the tag entry to the current
process's pqd_entry list, nor update sock_tag_entry->pid.
So the sock_tag_entry is only ever present in the
pqd_entry list of the process that initially tagged the socket.

A sock_tag_entry can also get created and not be added to any process's
pqd_entry list. This happens if the process that initially tags the
socket has not opened /dev/xt_qtaguid.

ctrl_cmd_untag() supports untagging from a context other than the
process that initially tagged the socket. Currently, the sock_tag_entry is
only removed from its containing pqd_entry->sock_tag_list if the
process that does the untagging has opened /dev/xt_qtaguid. However, the
tag entry should always be deleted from its pqd entry list (if present).

886fca85ed cfg80211: treat 6 GHz channels as valid regardless of capability
If a 6 GHz channel exists, then we can probably safely assume that
the device actually supports it, and then it should support most
bandwidths.

This will probably need to be extended to check the interface type
and then dig into the HE capabilities for that though, to have the
correct bandwidth check.

capabilities, instead the HE 6 GHz band capabilities will capture
the relevant information. Reject HT/VHT capabilities here.

519988fed6 cfg80211: add and expose HE 6 GHz band capabilities
These capabilities cover what would otherwise be transported
in HT/VHT capabilities, but only a subset thereof that is
actually needed on 6 GHz with HE already present. Expose the
capabilities to userspace, drivers are expected to set them
as using the 6 GHz band (currently) requires HE capability.

caa449d973 cfg80211: adapt to new channelization of the 6GHz band
The 6GHz band does not have regulatory approval yet, but things are
moving forward. However, that has led to a change in the channelization
of the 6GHz band which has been accepted in the 11ax specification. It
also fixes a missing MHZ_TO_KHZ() macro for 6GHz channels while at it.

This change is primarily thrown in to discuss how to deal with it.
I noticed ath11k adding 6G support with old channelization and ditto
for iw. It probably involves changes in hostapd as well.
