The root cause is traced to the vc_maps which alloced in open_card_oam()
are not freed in close_card_oam(). The vc_maps are used to record
open connections, so when close a vc_map in close_card_oam(), the memory
should be freed. Moreover, the ubr0 is not closed when close a idt77252
device, leading to the memory leak of vc_map and scq_info.
Fix them by adding kfree in close_card_oam() and implementing new
close_card_ubr0() to close ubr0.

[ Upstream commit 032a954061 ]
When BCM63xx internal switches are connected to switches with a 4-byte
Broadcom tag, it does not identify the packet as VLAN tagged, so it adds one
based on its PVID (which is likely 0).
Right now, the packet is received by the BCM63xx internal switch and the 6-byte
tag is properly processed. The next step would to decode the corresponding
4-byte tag. However, the internal switch adds an invalid VLAN tag after the
6-byte tag and the 4-byte tag handling fails.
In order to fix this we need to remove the invalid VLAN tag after the 6-byte
tag before passing it to the 4-byte tag decoding.

[ Upstream commit 662404b24a ]
Upon entering switchdev mode, VF/SF representors are spawned in the
devlink instance's net namespace, whereas the PF net device transforms
into the uplink representor, remaining in the net namespace the PF net
device was in. Therefore, if a PF net device's namespace is different from
its parent devlink net namespace, entering switchdev mode can create an
illegal situation where all representors sharing the same core device
are NOT in the same net namespace.
To avoid this issue, block entering switchdev mode for devices whose child
netdev net namespace has diverged from the parent devlink's.

We've seen recent AWS EKS (Kubernetes) user reports like the following:
After upgrading EKS nodes from v20230203 to v20230217 on our 1.24 EKS
clusters after a few days a number of the nodes have containers stuck
in ContainerCreating state or liveness/readiness probes reporting the
following error:
Readiness probe errored: rpc error: code = Unknown desc = failed to

OCI runtime exec failed: exec failed: unable to start container process:
unable to init seccomp: error loading seccomp filter into kernel:
error loading seccomp filter: errno 524: unknown
However, we had not been seeing this issue on previous AMIs and it only
started to occur on v20230217 (following the upgrade from kernel 5.4 to
5.10) with no other changes to the underlying cluster or workloads.
We tried the suggestions from that issue (sysctl net.core.bpf_jit_limit=452534528)
which helped to immediately allow containers to be created and probes to
execute but after approximately a day the issue returned and the value
returned by cat /proc/vmallocinfo | grep bpf_jit | awk '{s+=$2} END {print s}'
was steadily increasing.
I tested bpf tree to observe bpf_jit_charge_modmem, bpf_jit_uncharge_modmem
their sizes passed in as well as bpf_jit_current under tcpdump BPF filter,
seccomp BPF and native (e)BPF programs, and the behavior all looks sane
and expected, that is nothing "leaking" from an upstream perspective.
The bpf_jit_limit knob was originally added in order to avoid a situation
where unprivileged applications loading BPF programs (e.g. seccomp BPF
policies) consuming all the module memory space via BPF JIT such that loading
of kernel modules would be prevented. The default limit was defined back in
2018 and while good enough back then, we are generally seeing far more BPF
consumers today.
Adjust the limit for the BPF JIT pool from originally 1/4 to now 1/2 of the
module memory space to better reflect today's needs and avoid more users
running into potentially hard to debug issues.

During reboot all drivers PM shutdown callbacks are invoked.
In iavf_shutdown() the adapter state is changed to __IAVF_REMOVE.
In ice_shutdown() the call chain above is executed, which at some point
calls iavf_remove(). However iavf_remove() expects the VF to be in one
of the states __IAVF_RUNNING, __IAVF_DOWN or __IAVF_INIT_FAILED. If
that's not the case it sleeps forever.
So if iavf_shutdown() gets invoked before iavf_remove() the system will
hang indefinitely because the adapter is already in state __IAVF_REMOVE.
Fix this by returning from iavf_remove() if the state is __IAVF_REMOVE,
as we already went through iavf_shutdown().

[ Upstream commit 47f9e4c924 ]
The key which gets cached in task structure from a kernel thread does not
get invalidated even after expiry. Due to which, a new key request from
kernel thread will be served with the cached key if it's present in task
struct irrespective of the key validity. The change is to not cache key in
task_struct when key requested from kernel thread so that kernel thread
gets a valid key on every key request.
The problem has been seen with the cifs module doing DNS lookups from a
kernel thread and the results getting pinned by being attached to that
kernel thread's cache - and thus not something that can be easily got rid
of. The cache would ordinarily be cleared by notify-resume, but kernel
threads don't do that.
This isn't seen with AFS because AFS is doing request_key() within the
kernel half of a user thread - which will do notify-resume.

Since commit 6c40624930 ("bootconfig: Increase max nodes of bootconfig
from 1024 to 8192 for DCC support") increased the max number of bootconfig
node to 8192, the bootconfig testcase of the max number of nodes fails.
To fix this issue, we can not simply increase the number in the test script
because the test bootconfig file becomes too big (>32KB). To fix that, we
can use a combination of three alphabets (26^3 = 17576). But with that,
we can not express the 8193 (just one exceed from the limitation) because
it also exceeds the max size of bootconfig. So, the first 26 nodes will just
use one alphabet.
With this fix, test-bootconfig.sh passes all tests.

[ Upstream commit 6d206b1ea9 ]
The cooling levels array is supposed to prevent the system fans from
being configured below a 20% duty cycle as otherwise some of them get
stuck at 0 RPM.
Due to an off-by-one error, the last element in the array was not
initialized, causing it to be set to zero, which in turn lead to fans
being configured with a 0% duty cycle in maximum cooling state.
Since commit 332fdf951d ("mlxsw: thermal: Fix out-of-bounds memory
accesses") the contents of the array are static. Therefore, instead of
fixing the initialization of the array, simply remove it and adjust
thermal_cooling_device_ops::set_cur_state() so that the configured duty
cycle is never set below 20%.
Before:
# cat /sys/class/thermal/thermal_zone0/cdev0/type
mlxsw_fan
# echo 10 > /sys/class/thermal/thermal_zone0/cdev0/cur_state
# cat /sys/class/hwmon/hwmon0/name
mlxsw
# cat /sys/class/hwmon/hwmon0/pwm1
0
After:
# cat /sys/class/thermal/thermal_zone0/cdev0/type
mlxsw_fan
# echo 10 > /sys/class/thermal/thermal_zone0/cdev0/cur_state
# cat /sys/class/hwmon/hwmon0/name
mlxsw
# cat /sys/class/hwmon/hwmon0/pwm1

This bug was uncovered when the thermal subsystem repeatedly tried to
configure the cooling devices to their maximum state due to another
issue [1]. This resulted in the fans being stuck at 0 RPM, which
eventually lead to the system undergoing thermal shutdown.

another buffer (happens in case of TSO xmit) assuming that 32bit
addressing is used due to platform configuration but the device will
still use both descriptor addresses as one address.
This can be observed with the Intel EHL platform driver that sets
32bit for addr64 but the MAC reports 40bit. The TX queue gets stuck in
case of TCP with iptables NAT configuration on TSO packets.
The logic should be like this: Whatever we do on the host side (memory
allocation GFP flags) should happen with the host DMA width, whenever
we decide how to set addresses on the device registers we must use the
device DMA address width.
This patch renames the platform address width field from addr64 (term
used in device datasheet) to host_addr and uses this value exclusively
for host side operations while all chip operations consider the device
DMA width as read from the device register.

[ Upstream commit 27c934dd88 ]
The splice read calls nfsd_splice_actor to put the pages containing file
data into the svc_rqst->rq_pages array. It's possible however to get a
splice result that only has a partial page at the end, if (e.g.) the
filesystem hands back a short read that doesn't cover the whole page.
nfsd_splice_actor will plop the partial page into its rq_pages array and
return. Then later, when nfsd_splice_actor is called again, the
remainder of the page may end up being filled out. At this point,
nfsd_splice_actor will put the page into the array _again_ corrupting
the reply. If this is done enough times, rq_next_page will overrun the
array and corrupt the trailing fields -- the rq_respages and
rq_next_page pointers themselves.
If we've already added the page to the array in the last pass, don't add
it to the array a second time when dealing with a splice continuation.
This was originally handled properly in nfsd_splice_actor, but commit
91e23b1c39 ("NFSD: Clean up nfsd_splice_actor()") removed the check
for it.

then is the completion interrupt. So only use the completion interrupt
to finish the whole transfer process.

We found that after commit 9c46929e79
("ARM: implement THREAD_INFO_IN_TASK for uniprocessor systems"), the
PCF85063 RTC driver stopped working on i.MX28 due to regmap_bulk_read()
reading bogus data into a stack buffer. This is caused by the i2c-mxs
driver using DMA transfers even for messages without the I2C_M_DMA_SAFE
flag, and the aforementioned commit enabling vmapped stacks.
As the MXS I2C controller requires DMA for reads of >4 bytes, DMA can't be
disabled, so the issue is fixed by using i2c_get_dma_safe_msg_buf() to
create a bounce buffer when needed.

The check introduced in the commit a5fd39464a ("igc: Lift TAPRIO schedule
restriction") can detect a false positive error in some corner case.
For instance,
tc qdisc replace ... taprio num_tc 4
...
sched-entry S 0x01 100000 # slot#1
sched-entry S 0x03 100000 # slot#2
sched-entry S 0x04 100000 # slot#3
sched-entry S 0x08 200000 # slot#4
flags 0x02 # hardware offload
Here the queue#0 (the first queue) is on at the slot#1 and #2,
and off at the slot#3 and #4. Under the current logic, when the slot#4
is examined, validate_schedule() returns *false* since the enablement
count for the queue#0 is two and it is already off at the previous slot
(i.e. #3). But this definition is truely correct.
Let's fix the logic to enforce a strict validation for consecutively-opened
slots.

[257.483094] iavf 0000:00:03.0 enp0s3: Max allowed VLAN filters 8. Remove existing VLANs or disable filtering via Ethtool if supported.
The VF driver complains that it cannot add the VLAN 0 filter.
On the other hand, the PF driver always adds VLAN 0 filter on VF
initialization. The VF does not need to ask the PF for that filter at
all.
Fix the error by not tracking VLAN 0 filters altogether. With that, the
check added by commit 0e710a3ffd ("iavf: Fix VF driver counting VLAN 0
