[Qemu-devel] [PATCHv8 0/9] slirp: Adding IPv6 support to Qemu -net user mode

[Samuel Thibault <samuel.thibault@ens-lyon.org>]

Hello,

This is another respin of IPv6 in Qemu -net user mode.


These patches add ICMPv6, NDP, and make UDP and TCP compatible with
IPv6.


Difference with version 7 is:
- Fix overflow detection in strtol call
- Fix formatting and typos
- Use SLIRP_ prefix for header protection
- Use grand instead of srand/rand
- Use standard macros instead of defining intermediate in6_multicast and in6_unspecified
- Pass pointers to in6_equal* instead of structs
- Use qemu_log_mask(LOG_GUEST_ERROR) for guest errors instead of error_report()
- Use bool type
- Avoid floating point operation
- Include qemu/osdep.h in new files.
- Move code to send NA to separate function
- Fix memory leak
- Fix missing save_ip in UDPv6
- Fix zero UDP checksum
- Use unreachable assertion instead of simple breaks when the socket type is not v4 or v6.
- Avoid duplicate ipv4/ipv6 header save.

Here is a summary of the patches:

Guillaume Subiron (7):
  slirp: Adding IPv6, ICMPv6 Echo and NDP autoconfiguration
