[ Upstream commit 1fc62c8347397faf4e18249e88ecd4470c0a5357 ]

The SMMU GDSC doesn't have to be ALWAYS-ON and shouldn't feature the
HW_CTRL flag (it's separate from hw_ctrl_addr).  In addition to that,
it should feature a cxc entry for bimc_smmu_axi_clk and be marked as
votable.

Fix all of these issues.

50b5ee6f7e clk: qcom: clk-rcg2: Fix clock rate overflow for high parent frequencies
[ Upstream commit f7b7d30158cff246667273bd2a62fc93ee0725d2 ]

If the parent clock rate is greater than unsigned long max/2 then
integer overflow happens when calculating the clock rate on 32-bit systems.
As RCG2 uses half integer dividers, the clock rate is first being
multiplied by 2 which will overflow the unsigned long max value.
Hence, replace the common pattern of doing 64-bit multiplication
and then a do_div() call with simpler mult_frac call.

Both ipvlan_process_v4_outbound() and ipvlan_process_v6_outbound()
increment dev->stats.tx_errors in case of errors.

Unfortunately there are two issues :

1) ipvlan_get_stats64() does not propagate dev->stats.tx_errors to user.

2) Increments are not atomic. KCSAN would complain eventually.

Use DEV_STATS_INC() to not miss an update, and change ipvlan_get_stats64()
to copy the value back to user.

ee1c730fdd ipv6: avoid atomic fragment on GSO packets
[ 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.

60c874a705 ACPI: sysfs: Fix create_pnp_modalias() and create_of_modalias()
[ 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.

6e6dffbb72 bpf: Fix unnecessary -EBUSY from htab_lock_bucket
[ Upstream commit d35381aa73f7e1e8b25f3ed5283287a64d9ddff5 ]

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.

[ Upstream commit 658939fc68d3241f9a0019e224cd7154438c23f2 ]

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.

d04aaf89bf wifi: iwlwifi: mvm: update IGTK in mvmvif upon D3 resume
[ Upstream commit ac0c6fdc4c56b669abc1c4a323f1c7a3a1422dd2 ]

During the D3 resume flow, all new rekeys are passed from the FW.
Because the FW supports only one IGTK at a time, every IGTK rekey
update should be done by removing the last IGTK. The mvmvif holds a
pointer to the last IGTK for that reason and thus should be updated
when a new IGTK is passed upon resume.

When we want to synchronize the NAPI, which was added in
commit 5af2bb3168 ("wifi: iwlwifi: call napi_synchronize()
before freeing rx/tx queues"), we also need to make sure we
can't actually reschedule the NAPI. Yes, this happens while
interrupts are disabled, but interrupts may still be running
or pending. Also call iwl_pcie_synchronize_irqs() to ensure
we won't reschedule the NAPI.

[ Upstream commit 43874283ce6c5bd32ac9d30878b2c96a974357cb ]

When I implemented iwl_mvm_mac_flush_sta() I completely botched it;
it basically always happens after the iwl_mvm_sta_pre_rcu_remove()
call, and that already clears mvm->fw_id_to_mac_id[] entries, so we
cannot rely on those at iwl_mvm_mac_flush_sta() time. This means it
never did anything.

cookie_init_timestamp() is supposed to return a 64bit timestamp

Unfortunately it uses 32bit fields and overflows after

Generated TSval are still correct, but skb->tstamp might be set
far away in the past, potentially confusing other layers.

tcp_ns_to_ts() is changed to return a full 64bit value,
ts and ts_now variables are changed to u64 type,
and TSMASK is removed in favor of shifts operations.

While we are at it, change this sequence:
		ts >>= TSBITS;
		ts--;
		ts <<= TSBITS;
		ts |= options;
to:
		ts -= (1UL << TSBITS);

fb64fc9fac thermal: core: Don't update trip points inside the hysteresis range
[ Upstream commit cf3986f8c01d355490d0ac6024391b989a9d1e9d ]

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.

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.

ba36bc0eda bpf: Fix missed rcu read lock in bpf_task_under_cgroup()
[ Upstream commit 29a7e00ffadddd8d68eff311de1bf12ae10687bb ]

When employed within a sleepable program not under RCU protection, the
use of 'bpf_task_under_cgroup()' may trigger a warning in the kernel log,
particularly when CONFIG_PROVE_RCU is enabled:

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.

0fbeb803ef r8169: fix rare issue with broken rx after link-down on RTL8125
[ Upstream commit 621735f590643e3048ca2060c285b80551660601 ]

In very rare cases (I've seen two reports so far about different
RTL8125 chip versions) it seems the MAC locks up when link goes down
and requires a software reset to get revived.
Realtek doesn't publish hw errata information, therefore the root cause
is unknown. Realtek vendor drivers do a full hw re-initialization on
each link-up event, the slimmed-down variant here was reported to fix
the issue for the reporting user.
It's not fully clear which parts of the NIC are reset as part of the
software reset, therefore I can't rule out side effects.

39d591b0d6 virtio-net: fix the vq coalescing setting for vq resize
[ Upstream commit f61fe5f081cf40de08d0a4c89659baf23c900f0c ]

According to the definition of virtqueue coalescing spec[1]:

  Upon disabling and re-enabling a transmit virtqueue, the device MUST set
  the coalescing parameters of the virtqueue to those configured through the
  VIRTIO_NET_CTRL_NOTF_COAL_TX_SET command, or, if the driver did not set
  any TX coalescing parameters, to 0.

  Upon disabling and re-enabling a receive virtqueue, the device MUST set
  the coalescing parameters of the virtqueue to those configured through the
  VIRTIO_NET_CTRL_NOTF_COAL_RX_SET command, or, if the driver did not set
  any RX coalescing parameters, to 0.

We need to add this setting for vq resize (ethtool -G) where vq_reset happens.
