[ Upstream commit 03d6c848bfb406e9ef6d9846d759e97beaeea113 ]
When the ipv6 stack output a GSO packet, if its gso_size is larger than
dst MTU, then all segments would be fragmented. However, it is possible
for a GSO packet to have a trailing segment with smaller actual size
than both gso_size as well as the MTU, which leads to an "atomic
fragment". Atomic fragments are considered harmful in RFC-8021. An
Existing report from APNIC also shows that atomic fragments are more
likely to be dropped even it is equivalent to a no-op [1].
Add an extra check in the GSO slow output path. For each segment from
the original over-sized packet, if it fits with the path MTU, then avoid
generating an atomic fragment.

[ Upstream commit 48cf49d31994ff97b33c4044e618560ec84d35fb ]
snprintf() does not return negative values on error.
To know if the buffer was too small, the returned value needs to be
compared with the length of the passed buffer. If it is greater or
equal, the output has been truncated, so add checks for the truncation
to create_pnp_modalias() and create_of_modalias(). Also make them
return -ENOMEM in that case, as they already do that elsewhere.
Moreover, the remaining size of the buffer used by snprintf() needs to
be updated after the first write to avoid out-of-bounds access as
already done correctly in create_pnp_modalias(), but not in
create_of_modalias(), so change the latter accordingly.

htab_lock_bucket uses the following logic to avoid recursion:
1. preempt_disable();
2. check percpu counter htab->map_locked[hash] for recursion;
2.1. if map_lock[hash] is already taken, return -BUSY;
3. raw_spin_lock_irqsave();
However, if an IRQ hits between 2 and 3, BPF programs attached to the IRQ
logic will not able to access the same hash of the hashtab and get -EBUSY.
This -EBUSY is not really necessary. Fix it by disabling IRQ before
checking map_locked:
1. preempt_disable();
2. local_irq_save();
3. check percpu counter htab->map_locked[hash] for recursion;
3.1. if map_lock[hash] is already taken, return -BUSY;
4. raw_spin_lock().
Similarly, use raw_spin_unlock() and local_irq_restore() in
htab_unlock_bucket().

This enables a broadcast sink to be informed if the PA
it has synced with is associated with an encrypted BIG,
by retrieving the socket QoS and checking the encryption
field.
After PA sync has been successfully established and the
first BIGInfo advertising report is received, a new hcon
is added and notified to the ISO layer. The ISO layer
sets the encryption field of the socket and hcon QoS
according to the encryption parameter of the BIGInfo
advertising report event.
After that, the userspace is woken up, and the QoS of the
new PA sync socket can be read, to inspect the encryption
field and follow up accordingly.

If a TX queue has no space for new TX frames, the driver will keep
these frames in the overflow queue, and during reclaim flow it
will retry to send the frames from that queue.
But if the reclaim flow was invoked from TX queue flush, we will also
TX these frames, which is wrong as we don't want to TX anything
after flush.
This might also cause assert 0x125F when removing the queue,
saying that the driver removes a non-empty queue
Fix this by TXing the overflow queue's frames only if we are
not in flush queue flow.

When searching for the trip points that need to be set, the nearest
higher trip point's temperature is used for the high trip, while the
nearest lower trip point's temperature minus the hysteresis is used for
the low trip. The issue with this logic is that when the current
temperature is inside a trip point's hysteresis range, both high and low
trips will come from the same trip point. As a consequence instability
can still occur like this:
* the temperature rises slightly and enters the hysteresis range of a
trip point
* polling happens and updates the trip points to the hysteresis range
* the temperature falls slightly, exiting the hysteresis range, crossing
the trip point and triggering an IRQ, the trip points are updated
* repeat
So even though the current hysteresis implementation prevents
instability from happening due to IRQs triggering on the same
temperature value, both ways, it doesn't prevent it from happening due
to an IRQ on one way and polling on the other.
To properly implement a hysteresis behavior, when inside the hysteresis
range, don't update the trip points. This way, the previously set trip
points will stay in effect, which will in a way remember the previous
state (if the temperature signal came from above or below the range) and
therefore have the right trip point already set.
The exception is if there was no previous trip point set, in which case
a previous state doesn't exist, and so it's sensible to allow the
hysteresis range as trip points.
The following logs show the current behavior when running on a real
machine:

The linked list failure test 'pop_front_off' and 'pop_back_off'
currently rely on matching exact instruction and register values. The
purpose of the test is to ensure the offset is correctly incremented for
the returned pointers from list pop helpers, which can then be used with
container_of to obtain the real object. Hence, somehow obtaining the
information that the offset is 48 will work for us. Make the test more
robust by relying on verifier error string of bpf_spin_lock and remove
dependence on fragile instruction index or register number, which can be
affected by different clang versions used to build the selftests.

Assume that caller's 'to' offset really represents an upper boundary for
the pattern search, so patterns extending past this offset are to be
rejected.
The old behaviour also was kind of inconsistent when it comes to
fragmentation (or otherwise non-linear skbs): If the pattern started in
between 'to' and 'from' offsets but extended to the next fragment, it
was not found if 'to' offset was still within the current fragment.
Test the new behaviour in a kselftest using iptables' string match.

This issue can be reproduced by executing a straightforward program, as
demonstrated below:
SEC("lsm.s/bpf")
int BPF_PROG(lsm_run, int cmd, union bpf_attr *attr, unsigned int size)
{
struct cgroup *cgrp = NULL;
struct task_struct *task;
int ret = 0;
if (cmd != BPF_LINK_CREATE)
return 0;
// The cgroup2 should be mounted first
cgrp = bpf_cgroup_from_id(1);
if (!cgrp)
goto out;
task = bpf_get_current_task_btf();
if (bpf_task_under_cgroup(task, cgrp))
ret = -1;
bpf_cgroup_release(cgrp);
out:
return ret;
}
After running the program, if you subsequently execute another BPF program,
you will encounter the warning.
It's worth noting that task_under_cgroup_hierarchy() is also utilized by
bpf_current_task_under_cgroup(). However, bpf_current_task_under_cgroup()
doesn't exhibit this issue because it cannot be used in sleepable BPF
programs.

When frames are sent over the air, the device always applies the data
rates in descending order. The driver assumed Minstrel also provided
rate in descending order.
However, in some cases, Minstrel can a choose a fallback rate greater
than the primary rate. In this case, the two rates was inverted, the
device try highest rate first and we get many retries.
Since the device always applies rates in descending order, the
workaround is to drop the rate when it higher than its predecessor in
the rate list. Thus [ 4, 5, 3 ] becomes [ 4, 3 ].
This patch has been tested in isolated room with a series of

This race condition was discovered while updating the at91_can driver
to use can_bus_off(). The following scenario describes how the
converted at91_can driver would behave.
When a CAN device goes into BUS-OFF state, the driver usually
stops/resets the CAN device and calls can_bus_off().
This function sets the netif carrier to off, and (if configured by
user space) schedules a delayed work that calls can_restart() to
restart the CAN device.
The can_restart() function first checks if the carrier is off and
triggers an error message if the carrier is OK.
Then it calls the driver's do_set_mode() function to restart the
device, then it sets the netif carrier to on. There is a race window
between these two calls.
The at91 CAN controller (observed on the sama5d3, a single core 32 bit
ARM CPU) has a hardware limitation. If the device goes into bus-off
while sending a CAN frame, there is no way to abort the sending of
this frame. After the controller is enabled again, another attempt is
made to send it.
If the bus is still faulty, the device immediately goes back to the
bus-off state. The driver calls can_bus_off(), the netif carrier is
switched off and another can_restart is scheduled. This occurs within
the race window before the original can_restart() handler marks the
netif carrier as OK. This would cause the 2nd can_restart() to be
called with an OK netif carrier, resulting in an error message.
The flow of the 1st can_restart() looks like this:
can_restart()
// bail out if netif_carrier is OK
netif_carrier_ok(dev)
priv->do_set_mode(dev, CAN_MODE_START)
// enable CAN controller
// sama5d3 restarts sending old message
// CAN devices goes into BUS_OFF, triggers IRQ
// IRQ handler start
at91_irq()
at91_irq_err_line()
can_bus_off()
netif_carrier_off()
schedule_delayed_work()
// IRQ handler end
netif_carrier_on()
The 2nd can_restart() will be called with an OK netif carrier and the
error message will be printed.
To close the race window, first set the netif carrier to on, then
restart the controller. In case the restart fails with an error code,
roll back the netif carrier to off.

[ Upstream commit 77f1ee6fd8b6e470f721d05a2e269039d5cafcb7 ]
Tx power is fetched from firmware's pdev stats. However, during active
CAC, firmware does not fill the current Tx power and sends the max
initialised value filled during firmware init. If host sends this power
to user space, this is wrong since in certain situations, the Tx power
could be greater than the max allowed by the regulatory. Hence, host
should not be fetching the Tx power during an active CAC.
Fix this issue by returning -EAGAIN error so that user space knows that there's
no valid value available.

[ Upstream commit 2cf51f931797d9a47e75d999d0993a68cbd2a560 ]
A bulk transfer of the USB may contain many packets. And, the total
number of the packets in the bulk transfer may be more than budget.
Originally, only budget packets would be handled by napi_gro_receive(),
and the other packets would be queued in the driver for next schedule.
This patch would break the loop about getting next bulk transfer, when
the budget is exhausted. That is, only the current bulk transfer would
be handled, and the other bulk transfers would be queued for next
schedule. Besides, the packets which are more than the budget in the
current bulk trasnfer would be still queued in the driver, as the
original method.
In addition, a bulk transfer wouldn't contain more than 400 packets, so
the check of queue length is unnecessary. Therefore, I replace it with
WARN_ON_ONCE().
