[PATCH 00/10] New network driver for Amiga X-Surf 100 (m68k)

This patch series adds support for the Individual Computers X-Surf 100 network card for m68k Amiga, a network adapter based on the AX88796 chip set. The driver was originally written for kernel version 3.19 by Michael Karcher (see CC:), and adapted to 4.16 for submission to netdev by me.

[PATCH 03/10] net: ax88796: Do not free IRQ in ax_remove() (already freed in ax_close()).

From: John Paul Adrian Glaubitz This complements the fix in 82533ad9a1c that removed the free_irq call in the error path of probe, to also not call free_irq when remove is called to revert the effects of probe. Signed-off-by: Michael Karcher

[PATCH 10/10] net: New ax88796 platform driver for Amiga X-Surf 100 Zorro board (m68k)

Add platform device driver to populate the ax88796 platform data from information provided by the XSurf100 zorro device driver. This driver will have to be loaded before loading the ax88796 module, or compiled as built-in. Signed-off-by: Michael Karcher

[PATCH net,stable] tun: fix vlan packet truncation

Bogus trimming in tun_net_xmit() causes truncated vlan packets. skb->len is correct whether or not skb_vlan_tag_present() is true. There is no more reason to adjust the skb length on xmit in this driver than any other driver. tun_put_user() adds 4 bytes to the total for tagged packets because it

[PATCH bpf-next 2/3] libbpf: Support guessing post_bind{4,6} progs

libbpf can guess prog type and expected attach type based on section name. Add hints for "cgroup/post_bind4" and "cgroup/post_bind6" section names. Existing "cgroup/sock" is not changed, i.e. expected_attach_type for it is not set to `BPF_CGROUP_INET_SOCK_CREATE`, for backward compatibility.

[PATCH bpf-next 0/3] Add missing types to bpftool, libbpf

Add support for various BPF prog types and attach types that have been added to kernel recently but not to bpftool or libbpf yet. Andrey Ignatov (3): bpftool: Add missing prog types and attach types libbpf: Support guessing post_bind{4,6} progs libbpf: Type functions for raw tracepoints

[PATCH RESEND net-next v2] KEYS: DNS: limit the length of option strings

From: Eric Biggers Adding a dns_resolver key whose payload contains a very long option name resulted in that string being printed in full. This hit the WARN_ONCE() in set_precision() during the printk(), because printk() only supports a precision of up to 32767 bytes:
