sparse complains about some harmless endianness issues: > net/ipv4/ip_tunnel_core.c:225:43: warning: cast to restricted __be16 > net/ipv4/ip_tunnel_core.c:225:43: warning: incorrect type in initializer (different base types) > net/ipv4/ip_tunnel_core.c:225:43: expected restricted __be16 [usertype] mtu > net/ipv4/ip_tunnel_core.c:225:43: got unsigned short [usertype] iptunnel_pmtud_build_icmp() uses the wrong flavour of byte-order conversion when storing the MTU into the ICMPv4 packet. Use htons(), just like iptunnel_pmtud_build_icmpv6() does. > net/ipv4/ip_tunnel_core.c:248:35: warning: cast from restricted __be16 > net/ipv4/ip_tunnel_core.c:248:35: warning: incorrect type in argument 3 (different base types) > net/ipv4/ip_tunnel_core.c:248:35: expected unsigned short type > net/ipv4/ip_tunnel_core.c:248:35: got restricted __be16 [usertype] > net/ipv4/ip_tunnel_core.c:341:35: warning: cast from restricted __be16 > net/ipv4/ip_tunnel_core.c:341:35: warning: incorrect type in argument 3 (different base types) > net/ipv4/ip_tunnel_core.c:341:35: expected unsigned short type > net/ipv4/ip_tunnel_core.c:341:35: got restricted __be16 [usertype] eth_header() wants the Ethertype in host-order, use the correct flavour of byte-order conversion. > net/ipv4/ip_tunnel_core.c:600:45: warning: restricted __be16 degrades to integer > net/ipv4/ip_tunnel_core.c:609:30: warning: incorrect type in assignment (different base types) > net/ipv4/ip_tunnel_core.c:609:30: expected int type > net/ipv4/ip_tunnel_core.c:609:30: got restricted __be16 [usertype] > net/ipv4/ip_tunnel_core.c:619:30: warning: incorrect type in assignment (different base types) > net/ipv4/ip_tunnel_core.c:619:30: expected int type > net/ipv4/ip_tunnel_core.c:619:30: got restricted __be16 [usertype] > net/ipv4/ip_tunnel_core.c:629:30: warning: incorrect type in assignment (different base types) > net/ipv4/ip_tunnel_core.c:629:30: expected int type > net/ipv4/ip_tunnel_core.c:629:30: got restricted __be16 [usertype] The TUNNEL_* types are big-endian, so adjust the type of the local variable in ip_tun_parse_opts().

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
