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 net/ipv4/ip_output.c | 9 ++++-- net/ipv6/ip6_output.c | 78 ++++++++++++++++++++++++--------------------------- 2 files changed, 43 insertions(+), 44 deletions(-) -- 2.5.0 -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
