[ Upstream commit 41c5305cc3d827d2ea686533777a285176ae01a0 ]
Topology could have more instances of the tokens being searched for than
the number of sets that need to be copied. Stop copying token after the
limit of number of token instances has been reached. This worked before
only by chance as we had allocated more size for the tuples array than
the number of actual tokens being parsed.

[ Upstream commit a93d2afd3f77a7331271a0f25c6a11003db69b3c ]
When devm runs function in the "remove" path for a device it runs them
in the reverse order. That means that if you have parts of your driver
that aren't using devm or are using "roll your own" devm w/
devm_add_action_or_reset() you need to keep that in mind.
The mt8186 audio driver didn't quite get this right. Specifically, in
mt8186_init_clock() it called mt8186_audsys_clk_register() and then
went on to call a bunch of other devm function. The caller of
mt8186_init_clock() used devm_add_action_or_reset() to call
mt8186_deinit_clock() but, because of the intervening devm functions,
the order was wrong.
Specifically at probe time, the order was:
1. mt8186_audsys_clk_register()
2. afe_priv->clk = devm_kcalloc(...)
3. afe_priv->clk[i] = devm_clk_get(...)
At remove time, the order (which should have been 3, 2, 1) was:
1. mt8186_audsys_clk_unregister()
3. Free all of afe_priv->clk[i]
2. Free afe_priv->clk
The above seemed to be causing a use-after-free. Luckily, it's easy to
fix this by simply using devm more correctly. Let's move the
devm_add_action_or_reset() to the right place. In addition to fixing
the use-after-free, code inspection shows that this fixes a leak
(missing call to mt8186_audsys_clk_unregister()) that would have
happened if any of the syscon_regmap_lookup_by_phandle() calls in
mt8186_init_clock() had failed.

[ Upstream commit 948f072ada23e0a504c5e4d7d71d4c83bd0785ec ]
Since the ->xprt_ctxt pointer was added to svc_deferred_req, it has not
been sufficient to use kfree() to free a deferred request. We may need
to free the ctxt as well.
As freeing the ctxt is all that ->xpo_release_rqst() does, we repurpose
it to explicit do that even when the ctxt is not stored in an rqst.
So we now have ->xpo_release_ctxt() which is given an xprt and a ctxt,
which may have been taken either from an rqst or from a dreq. The
caller is now responsible for clearing that pointer after the call to
->xpo_release_ctxt.
We also clear dr->xprt_ctxt when the ctxt is moved into a new rqst when
revisiting a deferred request. This ensures there is only one pointer
to the ctxt, so the risk of double freeing in future is reduced. The
new code in svc_xprt_release which releases both the ctxt and any
rq_deferred depends on this.

[ Upstream commit eb8d3a2c809abd73ab0a060fe971d6b9019aa3c1 ]
When an RPC request is deferred, the rq_xprt_ctxt pointer is moved out
of the svc_rqst into the svc_deferred_req.
When the deferred request is revisited, the pointer is copied into
the new svc_rqst - and also remains in the svc_deferred_req.
In the (rare?) case that the request is deferred a second time, the old
svc_deferred_req is reused - it still has all the correct content.
However in that case the rq_xprt_ctxt pointer is NOT cleared so that
when xpo_release_xprt is called, the ctxt is freed (UDP) or possible
added to a free list (RDMA).
When the deferred request is revisited for a second time, it will
reference this ctxt which may be invalid, and the free the object a
second time which is likely to oops.
So change svc_defer() to *always* clear rq_xprt_ctxt, and assert that
the value is now stored in the svc_deferred_req.

[ Upstream commit 0f5bb36bf9b39a2a96e730bf4455095b50713f63 ]
When Universal DVB card is detaching, netup_unidvb_dma_fini()
uses del_timer() to stop dma->timeout timer. But when timer
handler netup_unidvb_dma_timeout() is running, del_timer()
could not stop it. As a result, the use-after-free bug could
happen. The process is shown below:
(cleanup routine) | (timer routine)
| mod_timer(&dev->tx_sim_timer, ..)
netup_unidvb_finidev() | (wait a time)
netup_unidvb_dma_fini() | netup_unidvb_dma_timeout()
del_timer(&dma->timeout); |
| ndev->pci_dev->dev //USE
Fix by changing del_timer() to del_timer_sync().

stp_set_state() should actually allow receiving BPDU while in LEARNING
mode which is not the case. Additionally, the BLOCKEN bit does not
actually forbid sending forwarded frames from that port. To fix this, add
a5psw_port_tx_enable() function which allows to disable TX. However, while
its name suggest that TX is totally disabled, it is not and can still
allow to send BPDUs even if disabled. This can be done by using forced
forwarding with the switch tagging mechanism but keeping "filtering"
disabled (which is already the case in the rzn1-a5sw tag driver). With
these fixes, STP support is now functional.

When client and server establish a connection through vsock,
the client send a request to the server to initiate the connection,
then start a timer to wait for the server's response. When the server's
RESPONSE message arrives, the timer also times out and exits. The
server's RESPONSE message is processed first, and the connection is
established. However, the client's timer also times out, the original
processing logic of the client is to directly set the state of this vsock
to CLOSE and return ETIMEDOUT. It will not notify the server when the port
is released, causing the server port remain.
when client's vsock_connect timeout，it should check sk state is
ESTABLISHED or not. if sk state is ESTABLISHED, it means the connection
is established, the client should not set the sk state to CLOSE

On some distributions, the rp_filter is automatically set (=1) by
default on a netdev basis (also on VRFs).
In an SRv6 End.DT4 behavior, decapsulated IPv4 packets are routed using
the table associated with the VRF bound to that tunnel. During lookup
operations, the rp_filter can lead to packet loss when activated on the
VRF.
Therefore, we chose to make this selftest more robust by explicitly
disabling the rp_filter during tests (as it is automatically set by some
Linux distributions).

[ Upstream commit 21a933c79a33add3612808f3be4ad65dd4dc026b ]
The srv6_end_dt4_l3vpn_test instantiates a virtual network consisting of
several routers (rt-1, rt-2) and hosts.
When the IPv6 addresses of rt-{1,2} routers are configured, the Deduplicate
Address Detection (DAD) kicks in when enabled in the Linux distros running
the selftests. DAD is used to check whether an IPv6 address is already
assigned in a network. Such a mechanism consists of sending an ICMPv6 Echo
Request and waiting for a reply.
As the DAD process could take too long to complete, it may cause the
failing of some tests carried out by the srv6_end_dt4_l3vpn_test script.
To make the srv6_end_dt4_l3vpn_test more robust, we disable DAD on routers
since we configure the virtual network manually and do not need any address
deduplication mechanism at all.

For errors after msm_submitqueue_get(), we need to drop the submitqueue
reference. Additionally after get_unused_fd() we need to drop the fd.
The ordering for dropping the queue lock and put_unused_fd() is not
important, so just move this all into out_post_unlock.

[ Upstream commit cf3128a7aca55b2eefb68281d44749c683bdc96f ]
xfrm_state_find() uses `encap_family` of the current template with
the passed local and remote addresses to find a matching state.
If an optional tunnel or BEET mode template is skipped in a mixed-family
scenario, there could be a mismatch causing an out-of-bounds read as
the addresses were not replaced to match the family of the next template.
While there are theoretical use cases for optional templates in outbound
policies, the only practical one is to skip IPComp states in inbound
policies if uncompressed packets are received that are handled by an
implicitly created IPIP state instead.

[ Upstream commit c2adb1877b76fc81ae041e1db1a6ed2078c6746b ]
System-wide TSC read could cause a drift in C0 percentage calculation.
Because if first TSC is read and then one by one mperf is read for all
cpus, this introduces drift between mperf reading of later CPUs and TSC
reading. To lower this drift read TSC per CPU and also just after mperf
read. This technique improves C0 percentage calculation in Mperf monitor.

[ Upstream commit 5c5a7680e67ba6fbbb5f4d79fa41485450c1985c ]
struct platform_driver::remove returning an integer made driver authors
expect that returning an error code was proper error handling. However
the driver core ignores the error and continues to remove the device
because there is nothing the core could do anyhow and reentering the
remove callback again is only calling for trouble.
So this is an source for errors typically yielding resource leaks in the
error path.
As there are too many platform drivers to neatly convert them all to
return void in a single go, do it in several steps after this patch:
a) Convert all drivers to implement .remove_new() returning void instead
of .remove() returning int;
b) Change struct platform_driver::remove() to return void and so make
it identical to .remove_new();
c) Change all drivers back to .remove() now with the better prototype;
d) drop struct platform_driver::remove_new().
While this touches all drivers eventually twice, steps a) and c) can be
done one driver after another and so reduces coordination efforts
immensely and simplifies review.

At this stage, we have an allow policy (with or without transforms)

the policy we looked up lets the packet through. The case of a
blocking policy is already handled separately, so we can remove this
check.

function are off, so it's very dangerous to wait on a regular

soft-power function. Also, some comments were reorganized and

[ Upstream commit 96da8f148396329ba769246cb8ceaa35f1ddfc48 ]
When dln2_setup_rx_urbs() in dln2_probe() fails, error out_free forgets
to call usb_put_dev() to decrease the refcount of dln2->usb_dev.
Fix this by adding usb_put_dev() in the error handling code of
dln2_probe().

[ Upstream commit ded99b89d25fd73a1d7bd910378e0339fd9d4c4a ]
The Android Lenovo Yoga Book X90F / X90L uses the same charger / fuelgauge
setup as the already supported Windows Lenovo Yoga Book X91F/L, add
a DMI match for this to intel_cht_wc_models with driver_data
set to INTEL_CHT_WC_LENOVO_YOGABOOK1.
When the quirk for the X91F/L was initially added it was written to
also apply to the X90F/L but this does not work because the Android
version of the Yoga Book uses completely different DMI strings.
Also adjust the X91F/L quirk to reflect that it only applies to
the X91F/L models.

[ Upstream commit e9537962519e88969f5f69cd0571eb4f6984403c ]
This reverts commit
443a98e649b4 ("soundwire: bus: use pm_runtime_resume_and_get()")
Change calls to pm_runtime_resume_and_get() back to pm_runtime_get_sync().
This fixes a usage count underrun caused by doing a pm_runtime_put() even
though pm_runtime_resume_and_get() returned an error.
The three affected functions ignore -EACCES error from trying to get
pm_runtime, and carry on, including a put at the end of the function.
But pm_runtime_resume_and_get() does not increment the usage count if it
returns an error. So in the -EACCES case you must not call
pm_runtime_put().
The documentation for pm_runtime_get_sync() says:
"Consider using pm_runtime_resume_and_get() ... as this is likely to
result in cleaner code."
In this case I don't think it results in cleaner code because the
pm_runtime_put() at the end of the function would have to be conditional on
the return value from pm_runtime_resume_and_get() at the top of the
function.
pm_runtime_get_sync() doesn't have this problem because it always
increments the count, so always needs a put. The code can just flow through
and do the pm_runtime_put() unconditionally.

[ Upstream commit 2367e0ecb498764e95cfda691ff0828f7d25f9a4 ]
There are two issues related to the number of ports coming from
Devicetree when exceeding in total QCOM_SDW_MAX_PORTS. Both lead to
incorrect memory accesses:
1. With DTS having too big value of input or output ports, the driver,
when copying port parameters from local/stack arrays into 'pconfig'
array in 'struct qcom_swrm_ctrl', will iterate over their sizes.
2. If DTS also has too many parameters for these ports (e.g.
qcom,ports-sinterval-low), the driver will overflow buffers on the
stack when reading these properties from DTS.
Add a sanity check so incorrect DTS will not cause kernel memory
corruption.
