Subject: [PATCH net-next v3 0/4] net: clean up interactions of CHECKSUM_PARTIAL and fragmentation

This series fixes wrong checksums on the wire for IPv4 and IPv6. Large
send buffers and especially NFS lead to wrong checksums in both IPv4
and IPv6.

CHECKSUM_PARTIAL skbs should not receive the respective fragmentations
functions, so we add WARN_ON_ONCE to those functions to fix up those as
soon as they get reported.

Thanks!

Changelog:
v2: added v4 checks
v3: removed WARN_ON_ONCES (advice by Tom Herbert)

Hannes Frederic Sowa (4):
  ipv4: no CHECKSUM_PARTIAL on MSG_MORE corked sockets
  ipv4: add defensive check for CHECKSUM_PARTIAL skbs in ip_fragment
  ipv6: no CHECKSUM_PARTIAL on MSG_MORE corked sockets
  ipv6: add defensive check for CHECKSUM_PARTIAL skbs in ip_fragment
