macvlan object is re-structured to hold tap related elements in a separate entity, tap_dev. Upon NETDEV_REGISTER device_event, tap_dev is registered with idr and fetched again on tap_open. Few of the tap functions are modified to accepted tap_dev as argument. tap_dev object includes callbacks to be used by underlying virtual interface to take care of tx and rx accounting.

udp_ioctl(), as its name suggests, is used by UDP protocols, but is also used by L2TP :( L2TP should use its own handler, because it really does not look the same. SIOCINQ for instance should not assume UDP checksum or headers. Thanks to Andrey and syzkaller team for providing the report and a nice reproducer. While crashes only happen on recent kernels (after commit 7c13f97f ("udp: do fwd memory scheduling on dequeue")), this probably needs to be backported to older kernels.

Jakub Kicinski says: ==================== Netronome NFP4000 and NFP6000 PF driver This is a base PF driver for Netronome NFP4000 and NFP6000 chips. This series doesn't add any exciting new features, it provides a foundation for supporting more advanced firmware applications. Patch 1 moves a bitfield-related helper from our BPF code to the global header. Patch 2 renames the kernel module and adds a new main file. We were considering 3-module approach (pf, vf, common netdev library) but ultimately settled on a single module to keep things simple. Patch 3 adds support for accessing chip internals. It provides a way of configuring access windows to different parts of chip memory and issuing pretty much any commands on chip's NoC. Patches 4, 5, 6, 7, 8 provide support for accessing and interpreting various hardware and firmware information structures. Patch 9 introduces service processor (NSP) ABI. This ABI gives us access to PHY/SFP module configuration and information as well as methods for unloading and loading application firmware. Patches 10 and 11 modify the existing netdev code to make it possible to support multi-port devices (sharing a PCI device). Patch 12 adds a new driver probe path which will be used for the PF PCI device IDs. It utilizes the newly added infrastructure and is able to load application FW and spawn netdevs for all card's ports. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>
