Control messages and muxed traffic may need ordered delivery.

This is probably not an NFS specific issue, though I guess possibly it is.
Forwarding to netdev in case someone wants to take a look at it.

With TCP MTU probing enabled and offload TX checksumming disabled,
tcp_mtu_probe() calculated the wrong checksum when a fragment being copied
into the probe's SKB had an odd length. This was caused by the direct use
of skb_copy_and_csum_bits() to calculate the checksum, as it pads the
fragment bein

Where is the code that calls netdev_tx_reset_queue()? This is needed in
the function that brings down the interface, did your test sur

Thanks for pointing this out, I will reorder the fields to:
struct hashlimit_cfg2 {
__u64 avg;/* Average secs between packets * scale */
__u64 burst;
__u32 mode; /* bitmask of XT_HASHLIMIT_HASH_* */
This should fix the hole and avoid padding.

This fix a pointer leak when an unprivileged eBPF program read a pointer
value from the context. Even if is_valid_access() returns a pointer
type, the eBPF verifier replace it with UNKNOWN_VALUE. The register
value containing an address is then allowed to leak. Moreover, this
prevented unprivileged

Are you referring to order of application into net-next?

Change predecrement compare to post decrement compare to avoid an
unsigned integer wrap-around comparison when decrementing idx in
the while loop.
For example, when idx is zero, the current situation will

The 'vlan modify' action allows to replace an existing 802.1q tag
according to user provided settings.
It accepts same arguments as the 'vlan push' action.
For example, this replaces vid 6 with vid 5:
