dt-bindings: net: tja11xx: fix the broken binding
As Rob pointed in another mail thread [1], the binding of tja11xx PHY
is completely broken, the schema cannot catch the error in the DTS. A
compatiable string must be needed if we want to add a custom propety.
So extract known PHY IDs from the tja11xx PHY drivers and convert them
into supported compatible string list to fix the broken binding issue.

selftests: net: csum: Fix checksums for packets with non-zero padding
Padding is not included in UDP and TCP checksums. Therefore, reduce the
length of the checksummed data to include only the data in the IP
payload. This fixes spurious reported checksum failures like
rx: pkt: sport=33000 len=26 csum=0xc850 verify=0xf9fe
pkt: bad csum
Technically it is possible for there to be trailing bytes after the UDP
data but before the Ethernet padding (e.g. if sizeof(ip) + sizeof(udp) +
udp.len < ip.len). However, we don't generate such packets.

net: phy: dp83822: Fix NULL pointer dereference on DP83825 devices
The probe() function is only used for DP83822 and DP83826 PHY,
leaving the private data pointer uninitialized for the DP83825 models
which causes a NULL pointer dereference in the recently introduced/changed
functions dp8382x_config_init() and dp83822_set_wol().
Add the dp8382x_probe() function, so all PHY models will have a valid
private data pointer to fix this issue and also prevent similar issues
in the future.

virtio_net: disable premapped mode by default
Now, the premapped mode encounters some problem.
http://lore.kernel.org/all/8b20cc28-45a9-4643-8e87-ba164a540c0a@oracle.com
So we disable the premapped mode by default.
We can re-enable it in the future.

net: ftgmac100: Enable TX interrupt to avoid TX timeout
Currently, the driver only enables RX interrupt to handle RX
packets and TX resources. Sometimes there is not RX traffic,
so the TX resource needs to wait for RX interrupt to free.
This situation will toggle the TX timeout watchdog when the MAC
TX ring has no more resources to transmit packets.
Therefore, enable TX interrupt to release TX resources at any time.
When I am verifying iperf3 over UDP, the network hangs.
Like the log below.

iperf3: error - the server has terminated
The network topology is FTGMAC connects directly to a PC.
UDP does not need to wait for ACK, unlike TCP.
Therefore, FTGMAC needs to enable TX interrupt to release TX resources instead
of waiting for the RX interrupt.

octeontx2-af: Modify SMQ flush sequence to drop packets
The current implementation of SMQ flush sequence waits for the packets
in the TM pipeline to be transmitted out of the link. This sequence
doesn't succeed in HW when there is any issue with link such as lack of
link credits, link down or any other traffic that is fully occupying the
link bandwidth (QoS). This patch modifies the SMQ flush sequence to
drop the packets after TL1 level (SQM) instead of polling for the packets
to be sent out of RPM/CGX link.

net: hsr: remove seqnr_lock
syzbot found a new splat [1]. Instead of adding yet another spin_lock_bh(&hsr->seqnr_lock) / spin_unlock_bh(&hsr->seqnr_lock) pair, remove seqnr_lock and use atomic_t for hsr->sequence_nr and hsr->sup_sequence_nr. This also avoid a race in hsr_fill_info(). Also remove interlink_sequence_nr which is unused.

Tracing fixes for 6.11:
- Fix adding a new fgraph callback after function graph tracing has already started. If the new caller does not initialize its hash before registering the fgraph_ops, it can cause a NULL pointer dereference. Fix this by adding a new parameter to ftrace_graph_enable_direct() passing in the newly added gops directly and not rely on using the fgraph_array[], as entries in the fgraph_array[] must be initialized.

In the rtla tool that uses timerlat, if it was killed just as it was shutting down, the signals can free the kthread and the timer. But the closing of the timerlat files could cause the hrtimer_cancel() to be called on the already freed timer. As the kthread variable is is set to NULL when the kthreads are stopped and the timers are freed it can be used to know not to call hrtimer_cancel() on the timer if the kthread variable is NULL. - Use a cpumask to keep track of osnoise/timerlat kthreads The timerlat tracer can use user space threads for its analysis. With the killing of the rtla tool, the kernel can get confused between if it is using a user space thread to analyze or one of its own kernel threads. When this confusion happens, kthread_stop() can be called on a user space thread and bad things happen. As the kernel threads are per-cpu, a bitmask can be used to know when a kernel thread is used or when a user space thread is used. - Add missing interface_lock to osnoise/timerlat stop_kthread() The stop_kthread() function in osnoise/timerlat clears the osnoise kthread variable, and if it was a user space thread does a put_task on it. But this can race with the closing of the timerlat files that also does a put_task on the kthread, and if the race happens the task will have put_task called on it twice and oops. - Add cond_resched() to the tracing_iter_reset() loop. The latency tracers keep writing to the ring buffer without resetting when it issues a new "start" event (like interrupts being disabled). When reading the buffer with an iterator, the tracing_iter_reset() sets its pointer to that start event by walking through all the events in the buffer until it gets to the time stamp of the start event. In the case of a very large buffer, the loop that looks for the start event has been reported taking a very long time with a non preempt kernel that it can trigger a soft lock up warning. Add a cond_resched() into that loop to make sure that doesn't happen. - Use list_del_rcu() for eventfs ei->list variable It was reported that running loops of creating and deleting kprobe events could cause a crash due to the eventfs list iteration hitting a LIST_POISON variable. This is because the list is protected by SRCU but when an item is deleted from the list, it was using list_del() which poisons the "next" pointer. This is what list_del_rcu() was to prevent. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZtohNBQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qtoNAQDQKjomYLCpLz2EqgHZ6VB81QVrHuqt cU7xuEfUJDzyyAEA/n0t6quIdjYRd6R2/KxGkP6By/805Coq4IZMTgNQmw0= =nZ7k -----END PGP SIGNATURE----- Merge tag 'trace-v6.11-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Fix adding a new fgraph callback after function graph tracing has already started.

ila: call nf_unregister_net_hooks() sooner
syzbot found an use-after-free Read in ila_nf_input [1]
Issue here is that ila_xlat_exit_net() frees the rhashtable,
then call nf_unregister_net_hooks().
It should be done in the reverse way, with a synchronize_rcu().
This is a good match for a pre_exit() method.

op = self.rsp_by_value[nl_msg.cmd()]
KeyError: 19
Parsing Generic Netlink notification messages performs lookup for op in
the message. The message was not yet decoded, and is not yet considered
GenlMsg, thus msg.cmd() returns Generic Netlink family id (19) instead of
proper notification command id (i.e.: DPLL_CMD_PIN_CHANGE_NTF=13).
Allow the op to be obtained within NetlinkProtocol.decode(..) itself if the
op was not passed to the decode function, thus allow parsing of Generic
Netlink notifications without causing the failure.

tracing/timerlat: Add interface_lock around clearing of kthread in stop_kthread()
The timerlat interface will get and put the task that is part of the
"kthread" field of the osn_var to keep it around until all references are
released. But here's a race in the "stop_kthread()" code that will call
put_task_struct() on the kthread if it is not a kernel thread. This can
race with the releasing of the references to that task struct and the
put_task_struct() can be called twice when it should have been called just
once.
Take the interface_lock() in stop_kthread() to synchronize this change.
But to do so, the function stop_per_cpu_kthreads() needs to change the
loop from for_each_online_cpu() to for_each_possible_cpu() and remove the
cpu_read_lock(), as the interface_lock can not be taken while the cpu
locks are held. The only side effect of this change is that it may do some
extra work, as the per_cpu variables of the offline CPUs would not be set
anyway, and would simply be skipped in the loop.
Remove unneeded "return;" in stop_kthread().

tracing/timerlat: Only clear timer if a kthread exists
The timerlat tracer can use user space threads to check for osnoise and
timer latency. If the program using this is killed via a SIGTERM, the
threads are shutdown one at a time and another tracing instance can start
up resetting the threads before they are fully closed. That causes the
hrtimer assigned to the kthread to be shutdown and freed twice when the
dying thread finally closes the file descriptors, causing a use-after-free
bug.
Only cancel the hrtimer if the associated thread is still around. Also add
the interface_lock around the resetting of the tlat_var->kthread.
Note, this is just a quick fix that can be backported to stable. A real
fix is to have a better synchronization between the shutdown of old
threads and the starting of new ones.

The start_kthread() and stop_thread() code was not always called with the

should not have been, leading to:
while true; do

This is because it would mistakenly call kthread_stop() on a user space
thread making it "exit" before it actually exits.
Since kthreads are created based on global behavior, use a cpumask to know
when kthreads are running and that they need to be shutdown before
proceeding to do new work.

eventfs: Use list_del_rcu() for SRCU protected list variable
Chi Zhiling reported:
We found a null pointer accessing in tracefs[1], the reason is that the
variable 'ei_child' is set to LIST_POISON1, that means the list was
removed in eventfs_remove_rec. so when access the ei_child->is_freed, the
panic triggered.
by the way, the following script can reproduce this panic
loop1 (){
while true
do
echo "p:kp submit_bio" > /sys/kernel/debug/tracing/kprobe_events
echo "" > /sys/kernel/debug/tracing/kprobe_events

The issue is that list_del() is used on an SRCU protected list variable
before the synchronization occurs. This can poison the list pointers while
there is a reader iterating the list.
This is simply fixed by using list_del_rcu() that is specifically made for
this purpose.

tracing: Avoid possible softlockup in tracing_iter_reset()
In __tracing_open(), when max latency tracers took place on the cpu,
the time start of its buffer would be updated, then event entries with
timestamps being earlier than start of the buffer would be skipped
(see tracing_iter_reset()).
Softlockup will occur if the kernel is non-preemptible and too many
entries were skipped in the loop that reset every cpu buffer, so add
cond_resched() to avoid it.

sched: sch_cake: fix bulk flow accounting logic for host fairness
In sch_cake, we keep track of the count of active bulk flows per host,
when running in dst/src host fairness mode, which is used as the
round-robin weight when iterating through flows. The count of active
bulk flows is updated whenever a flow changes state.
This has a peculiar interaction with the hash collision handling: when a
hash collision occurs (after the set-associative hashing), the state of
the hash bucket is simply updated to match the new packet that collided,
and if host fairness is enabled, that also means assigning new per-host
state to the flow. For this reason, the bulk flow counters of the
host(s) assigned to the flow are decremented, before new state is
assigned (and the counters, which may not belong to the same host
anymore, are incremented again).
Back when this code was introduced, the host fairness mode was always
enabled, so the decrement was unconditional. When the configuration
flags were introduced the *increment* was made conditional, but
the *decrement* was not. Which of course can lead to a spurious
decrement (and associated wrap-around to U16_MAX).
AFAICT, when host fairness is disabled, the decrement and wrap-around
happens as soon as a hash collision occurs (which is not that common in
itself, due to the set-associative hashing). However, in most cases this
is harmless, as the value is only used when host fairness mode is
enabled. So in order to trigger an array overflow, sch_cake has to first
be configured with host fairness disabled, and while running in this
mode, a hash collision has to occur to cause the overflow. Then, the
qdisc has to be reconfigured to enable host fairness, which leads to the
array out-of-bounds because the wrapped-around value is retained and
used as an array index. It seems that syzbot managed to trigger this,
which is quite impressive in its own right.
This patch fixes the issue by introducing the same conditional check on
decrement as is used on increment.
The original bug predates the upstreaming of cake, but the commit listed
in the Fixes tag touched that code, meaning that this patch won't apply
before that.

net: bridge: br_fdb_external_learn_add(): always set EXT_LEARN
When userspace wants to take over a fdb entry by setting it as
EXTERN_LEARNED, we set both flags BR_FDB_ADDED_BY_EXT_LEARN and
BR_FDB_ADDED_BY_USER in br_fdb_external_learn_add().
If the bridge updates the entry later because its port changed, we clear
the BR_FDB_ADDED_BY_EXT_LEARN flag, but leave the BR_FDB_ADDED_BY_USER
flag set.
If userspace then wants to take over the entry again,
br_fdb_external_learn_add() sees that BR_FDB_ADDED_BY_USER and skips
setting the BR_FDB_ADDED_BY_EXT_LEARN flags, thus silently ignores the
update.
Fix this by always allowing to set BR_FDB_ADDED_BY_EXT_LEARN regardless
if this was a user fdb entry or not.

r8152: fix the firmware doesn't work
generic_ocp_write() asks the parameter "size" must be 4 bytes align.
Therefore, write the bp would fail, if the mac->bp_num is odd. Align the
size to 4 for fixing it. The way may write an extra bp, but the
rtl8152_is_fw_mac_ok() makes sure the value must be 0 for the bp whose
index is more than mac->bp_num. That is, there is no influence for the
firmware.
Besides, I check the return value of generic_ocp_write() to make sure
everything is correct.

fou: Fix null-ptr-deref in GRO.
We observed a null-ptr-deref in fou_gro_receive() while shutting down
a host. [0]
The NULL pointer is sk->sk_user_data, and the offset 8 is of protocol
in struct fou.
When fou_release() is called due to netns dismantle or explicit tunnel
teardown, udp_tunnel_sock_release() sets NULL to sk->sk_user_data.
Then, the tunnel socket is destroyed after a single RCU grace period.
So, in-flight udp4_gro_receive() could find the socket and execute the
FOU GRO handler, where sk->sk_user_data could be NULL.
Let's use rcu_dereference_sk_user_data() in fou_from_sock() and add NULL
checks in FOU GRO handlers.
