01c727402d net: dsa: mt7530: move lowering TRGMII driving to mt7530_setup()
[ Upstream commit fdcc8ccd82 ]

Move lowering the TRGMII Tx clock driving to mt7530_setup(), after setting
the core clock, as seen on the U-Boot MediaTek ethernet driver.

Move the code which looks like it lowers the TRGMII Rx clock driving to
after the TRGMII Tx clock driving is lowered. This is run after lowering
the Tx clock driving on the U-Boot MediaTek ethernet driver as well.

This way, the switch should consume less power regardless of port 6 being
used.

Update the comment explaining mt7530_pad_clk_setup().

Tested rgmii and trgmii modes of port 6 and rgmii mode of port 5 on MCM
MT7530 on MT7621AT Unielec U7621-06 and standalone MT7530 on MT7623NI
Bananapi BPI-R2.

5163bb8e4c net: dsa: mt7530: move enabling disabling core clock to mt7530_pll_setup()
[ Upstream commit 8f058a6ef9 ]

Split the code that enables and disables TRGMII clocks and core clock.
Move enabling and disabling core clock to mt7530_pll_setup() as it's
supposed to be run there.

Add 20 ms delay before enabling the core clock as seen on the U-Boot
MediaTek ethernet driver.

Change the comment for enabling and disabling TRGMII clocks as the code
seems to affect both TXC and RXC.

a76d35f344 gve: Cache link_speed value from device
[ Upstream commit 68c3e4fc86 ]

The link speed is never changed for the uptime of a VM, and the current
implementation sends an admin queue command for each call. Admin queue
command invocations have nontrivial overhead (e.g., VM exits), which can
be disruptive to users if triggered frequently. Our telemetry data shows
that there are VMs that make frequent calls to this admin queue command.
Caching the result of the original admin queue command would eliminate
the need to send multiple admin queue commands on subsequent calls to
retrieve link speed.

7a83bb6d56 hvc/xen: prevent concurrent accesses to the shared ring
[ Upstream commit 6214894f49 ]

The hvc machinery registers both a console and a tty device based on
the hv ops provided by the specific implementation.  Those two
interfaces however have different locks, and there's no single locks
that's shared between the tty and the console implementations, hence
the driver needs to protect itself against concurrent accesses.
Otherwise concurrent calls using the split interfaces are likely to
corrupt the ring indexes, leaving the console unusable.

Introduce a lock to xencons_info to serialize accesses to the shared
ring.  This is only required when using the shared memory console,
concurrent accesses to the hypercall based console implementation are
not an issue.

Note the conditional logic in domU_read_console() is slightly modified
so the notify_daemon() call can be done outside of the locked region:
it's an hypercall and there's no need for it to be done with the lock
held.

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.

48f52431af net: dsa: tag_brcm: legacy: fix daisy-chained switches
[ 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.

When ETS configurations are queried by the user to get the mapping
assignment between packet priority and traffic class, only priorities up

TC #0 which might be misleading.

Fix by querying the TC mapping of all priorities on each ETS query,
regardless of the maximum number of TCs configured in FW.

EEH happens. Since the vport's promisc settings(uc, mc and all) in

software rules are no longer valid.

Fix by nullifying these rules right after delete to avoid accessing any dangling

2b0f1716c1 net/mlx5e: Set uplink rep as NETNS_LOCAL
[ Upstream commit c83172b063 ]

Previously, NETNS_LOCAL was not set for uplink representors, inconsistent
with VF representors, and allowed the uplink representor to be moved
between net namespaces and separated from the VF representors it shares
the core device with. Such usage would break the isolation model of
namespaces, as devices in different namespaces would have access to
shared memory.

To solve this issue, set NETNS_LOCAL for uplink representors if eswitch is
in switchdev mode.

54869daa6a bpf: Adjust insufficient default bpf_jit_limit
[ Upstream commit 10ec8ca8ec ]

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
    exec in container: failed to start exec "4a11039f730203ffc003b7[...]":
    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().

ce19c70f30 keys: Do not cache key in task struct if key is requested from kernel thread
[ 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.

0cb68c307e bootconfig: Fix testcase to increase max node
[ Upstream commit b69245126a ]

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.

257738627a i2c: hisi: Only use the completion interrupt to finish the transfer
[ Upstream commit d982635126 ]

The controller will always generate a completion interrupt when the
transfer is finished normally or not. Currently we use either error or
completion interrupt to finish, this may result the completion
interrupt unhandled and corrupt the next transfer, especially at low
speed mode. Since on error case, the error interrupt will come first
then is the completion interrupt. So only use the completion interrupt
to finish the whole transfer process.

c0deddabb2 i2c: imx-lpi2c: check only for enabled interrupt flags
[ Upstream commit 1c78850045 ]

When reading from I2C, the Tx watermark is set to 0. Unfortunately the
TDF (transmit data flag) is enabled when Tx FIFO entries is equal or less
than watermark. So it is set in every case, hence the reset default of 1.
This results in the MSR_RDF _and_ MSR_TDF flags to be set thus trying
to send Tx data on a read message.
Mask the IRQ status to filter for wanted flags only.

b82b0a0eea igc: fix the validation logic for taprio's gate list
[ Upstream commit 2b4cc3d3f4 ]

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.

[ Upstream commit 02c83791ef ]

vf reset nack actually represents the reset operation itself is
performed but no address is assigned. Therefore, e1000_reset_hw_vf
should fill the "perm_addr" with the zero address and return success on
such an occasion. This prevents its callers in netdev.c from saying PF
still resetting, and instead allows them to correctly report that no
address is assigned.

2afe7aebf6 iavf: fix non-tunneled IPv6 UDP packet type and hashing
[ Upstream commit de58647b43 ]

Currently, IAVF's decode_rx_desc_ptype() correctly reports payload type
of L4 for IPv4 UDP packets and IPv{4,6} TCP, but only L3 for IPv6 UDP.
Originally, i40e, ice and iavf were affected.
Commit 73df8c9e3e ("i40e: Correct UDP packet header for non_tunnel-ipv6")
fixed that in i40e, then
commit 638a0c8c88 ("ice: fix incorrect payload indicator on PTYPE")
fixed that for ice.
IPv6 UDP is L4 obviously. Fix it and make iavf report correct L4 hash
type for such packets, so that the stack won't calculate it on CPU when
needs it.

2ebe231aba trace/hwlat: Do not start per-cpu thread if it is already running

The hwlatd tracer will end up starting multiple per-cpu threads with

    cd /sys/kernel/debug/tracing
    echo 0 > tracing_on
    echo hwlat > current_tracer
    echo per-cpu > hwlat_detector/mode
    echo 100000 > hwlat_detector/width
    echo 200000 > hwlat_detector/window
    echo 1 > tracing_on

To fix the issue, check if the hwlatd thread for the cpu is already
running, before starting a new one. Along with the previous patch, this
avoids running multiple instances of the same CPU thread on the system.
