[Qemu-devel] [PATCH] linux-user/syscall: let recvfrom(struct sockaddr *) use abi_ulong
Posted by Philippe Mathieu-Daudé 6 years, 3 months ago 
Currently recvfrom() is restricted to handle 32-bit pointers,
remove this limit for 64-bit hosts.

This fixes:

  31572 socket(AF_NETLINK, SOCK_RAW, NETLINK_AUDIT) = 3
  ...
  31572 sendto(3, {{len=124, type=0x454 /* NLMSG_??? */, flags=NLM_F_REQUEST|NLM_F_ACK, seq=1, pid=0}, "op=test:message acct=\"?\" exe=\"/tmp/nl-bad-addr\" hostname=localhost addr=? terminal=/dev/pts/2 res=success\0\0\0"}, 124, 0, 0xfffffa3897d0, 0) = 124
  31572 ppoll([{fd=3, events=POLLIN}], 1, {tv_sec=0, tv_nsec=500000000}, NULL, 0) = 1 ([{fd=3, revents=POLLIN}], left {tv_sec=0, tv_nsec=499993180})
  31572 recvfrom(3, 0x112a50eb4, 8988, MSG_PEEK|MSG_DONTWAIT, 0xfffffa3897e0, 0x42) = -1 EFAULT (Bad address)

I think there are more problems like that (accept4(), do_getpeername(),
do_getsockname()).

Could you check and fix?

I'm currently reviewing those ;)

I sent this patch first so Guido could start trying.

Ahh...I saw these and was wondering how this would work on
64bit. Unfortunately the patch doesn't change things:

    4824  recvfrom(3, 0x1401f8eb4, 8988, MSG_PEEK|MSG_DONTWAIT, 0xffffe10a8620, 0x42) = -1 EFAULT (Bad address)

If you want me to report qemu -strace or s.th. please let me know.
Cheers,

And more, I don't think the patch is correct.

get_user_u32()/put_user_u32() should be correct because in kernel this
is an "int *". And "int" is always 32bit. Only ptr and long vary.

Thanks,
Laurent

Could you try:

strace -f chroot . /usr/bin/qemu-arm-static tmp/nl-bad-addr

to see if the fault comes from the kernel or from QEMU.

(either host_msg or addr). It's weird...
