It is currently impossible to enable ipv6 forwarding on a per-interface basis like in ipv4. To enable forwarding on an ipv6 interface we need to enable it on all interfaces and disable it on the other interfaces using a netfilter rule. This is especially cumbersome if you have lots of interfaces and only want to enable forwarding on a few. According to the sysctl docs [0] the `net.ipv6.conf.all.forwarding` enables forwarding for all interfaces, while the interface-specific `net.ipv6.conf.<interface>.forwarding` configures the interface Host/Router configuration. Introduce a new sysctl flag `force_forwarding`, which can be set on every interface. The ip6_forwarding function will then check if the global forwarding flag OR the force_forwarding flag is active and forward the packet. To preserve backwards-compatibility reset the flag (on all interfaces) to 0 if the net.ipv6.conf.all.forwarding flag is set to 0. Add a short selftest that checks if a packet gets forwarded with and without `force_forwarding`.

The devlink_nl_rate_tc_bw_parse function uses a large stack array for
devlink attributes, which triggers a warning about excessive stack
usage:
net/devlink/rate.c: In function 'devlink_nl_rate_tc_bw_parse':
net/devlink/rate.c:382:1: error: the frame size of 1648 bytes is larger than 1536 bytes [-Werror=frame-larger-than=]
Introduce a separate attribute set specifically for rate TC bandwidth
parsing that only contains the two attributes actually used: index
and bandwidth. This reduces the stack array from DEVLINK_ATTR_MAX
entries to just 2 entries, solving the stack usage issue.
Update devlink selftest to use the new 'index' and 'bw' attribute names
consistent with the YAML spec.
Example usage with ynl with the new spec:
./tools/net/ynl/cli.py --spec Documentation/netlink/specs/devlink.yaml \
--do rate-set --json '{
"bus-name": "pci",
"dev-name": "0000:08:00.0",
"port-index": 1,
"rate-tc-bws": [
{"index": 0, "bw": 50},
{"index": 1, "bw": 50},
{"index": 2, "bw": 0},
{"index": 3, "bw": 0},
{"index": 4, "bw": 0},
{"index": 5, "bw": 0},
{"index": 6, "bw": 0},
{"index": 7, "bw": 0}
]
}'
./tools/net/ynl/cli.py --spec Documentation/netlink/specs/devlink.yaml \
--do rate-get --json '{
"bus-name": "pci",
"dev-name": "0000:08:00.0",
"port-index": 1
}'
output for rate-get:

'port-index': 1,

…priv::do_set_mode Andrei Lalaev reported a NULL pointer deref when a CAN device is restarted from Bus Off and the driver does not implement the struct can_priv::do_set_mode callback. There are 2 code path that call struct can_priv::do_set_mode: - directly by a manual restart from the user space, via can_changelink() - delayed automatic restart after bus off (deactivated by default) To prevent the NULL pointer deference, refuse a manual restart or configure the automatic restart delay in can_changelink() and report the error via extack to user space. As an additional safety measure let can_restart() return an error if can_priv::do_set_mode is not set instead of dereferencing it unchecked.

A few packets may still be sent out during the termination of iperf
processes. These late packets cause failures in rss_ctx.py when they
arrive on queues expected to be empty.
Example failure observed:
Check failed 2 != 0 traffic on inactive queues (context 1):
[0, 0, 1, 1, 386385, 397196, 0, 0, 0, 0, ...]
Check failed 4 != 0 traffic on inactive queues (context 2):
[0, 0, 0, 0, 2, 2, 247152, 253013, 0, 0, ...]
Check failed 2 != 0 traffic on inactive queues (context 3):
[0, 0, 0, 0, 0, 0, 1, 1, 282434, 283070, ...]
To avoid such failures, wait until all client sockets for the requested
port are either closed or in the TIME_WAIT state.

The SMMU engine on HIP09 chip has a hardware issue. SMMU pagetable prefetch features may prefetch and use a invalid PTE even the PTE is valid at that time. This will cause the device trigger fake pagefaults. The solution is to avoid prefetching by adding a SYNC command when smmu mapping a iova. But the performance of nic has a sharp drop. Then we do this workaround, always enable tx bounce buffer, avoid mapping/unmapping on TX path. This issue only affects HNS3, so we always enable tx bounce buffer when smmu enabled to improve performance.
