[Qemu-devel] [PATCH v3 0/5] linux-user: manage SOCK_PACKET socket type

[Laurent Vivier <laurent@vivier.eu>]

This is obsolete, but if we want to use dhcp with some distros (like debian
ppc 8.2 jessie), we need it.

bind() uses an interface name instead an interface index, and socket()
needs network order value to encode the protocol.

v3: update cover letter message,
    insert Reviewed-by: in PATCH 1 and PATCH 2
    insert fd_trans_target_to_host_addr into target_to_host_sockaddr and
    pass fd, check fd is >= 0, rename packet_target_to_host_addr to
    packet_target_to_host_sockaddr

v2: Split the patch in 4 parts to manage protocol endianness (socket()) and
    interface name (bind()) in different patches.
    Use TargetFdTrans array to manage the SOCK_PACKET type special case in
    bind().
    The two others patches are here to introduce a new function in TargetFdTrans
    to translate sockaddr data structure (rename previous functions to be
    clear).

Laurent Fiver (5):
  linux-user: SOCK_PACKET uses network endian to encode protocol in
    socket()
  linux-user: rename TargetFdFunc to TargetFdDataFunc,     and structure
    fields accordingly
  linux-user: add a function hook to translate sockaddr
  linux-user: manage bind with a socket of SOCK_PACKET type.
  linux-user: check fd is >= 0     in
    fd_trans_host_to_target_data/fd_trans_host_to_target_addr
