Public bug reported:
linux-user/syscall.c's do_socket function contains socket type remapping
to work around the nonsensically-permuted MIPS socket types. However, it
fails to account for the SOCK_NONBLOCK and SOCK_CLOEXEC flags that may
be or'd onto the type. Thus, a call from the application such as:
socket(AF_INET, SOCK_STREAM, IPPROTO_TCP)
will fail to have the type permutation performed, and will be passed to
the system as:
socket(AF_INET, SOCK_DGRAM, IPPROTO_TCP)
resulting in EPROTONOSUPPORT.
To fix this, the flag bits should be masked off of the type before the
permutation. They also need remapping themselves (since MIPS uses
different values for these flags bits).

This should be fixed in QEMU 1.6.
