[Qemu-devel] [Bug 824650] Re: Latest GIT assert error in arp_table.c

[Roy Tam]

let me make comment on current git (v1.0-1172-g235fe3b), my XP SP3 -net dump is 
attached.
You can see slirp almost not returning anything to guest (10.0.2.15), while the 
outgoing packets seem to be delivered correctly.

** Attachment added: "net dump from v1.0-1172-g235fe3b with XP SP3 guest"

  Fix Released

Bug description:
  The latest git version of qemu (commit
  8cc7c3952d4d0a681d8d4c3ac89a206a5bfd7f00) crashes after a few minutes.
  All was fine up to a few days ago.  This is wth both x86 and sparc
  emulation, on an x86_64 host.

  e.g. qemu-system-sparc -drive
  file=netbsd5.0.2-sparc,index=0,media=disk,cache=unsafe -m 256 -boot c
  -nographic -redir tcp:2232::22:

   qemu-system-sparc: slirp/arp_table.c:75: arp_table_search: Assertion
  `(ip_addr & (__extension__ ({ register unsigned int __v, __x = (~(0xf
  << 28)); if (__builtin_constant_p (__x)) __v = ((((__x) & 0xff000000)
  >> 24) | (((__x) & 0x00ff0000) >> 8) | (((__x) & 0x0000ff00) << 8) |
  (((__x) & 0x000000ff) << 24)); else __asm__ ("bswap %0" : "=r" (__v) :
  "0" (__x)); __v; }))) != 0' failed.
