Use TCP_CORK to remove a violation of encapsulation, that would later require nbd_trip to know too much about an NBD reply. We could also switch to sendmsg (qemu_co_sendv) later, it is even easier once coroutines are in. Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com>

Update ioctl(s) in nbd_init() to detect device busy early. Current nbd_init() issues NBD_CLEAR_SOCKET before NBD_SET_SOCKET, if issuing "qemu-nbd -c /dev/nbd0 disk.img" twice, the second time won't detect EBUSY in nbd_init(), but in nbd_client will report EBUSY and do clear socket (the 1st time command will be affacted too because of no socket any more.) No change to previous version. Signed-off-by: NChunyan Liu <cyliu@suse.com> Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com>

Outside coroutines, avoid busy waiting on EAGAIN by temporarily making the socket blocking. The API of qemu_recvv/qemu_sendv is slightly different from do_readv/do_writev because they do not handle coroutines. It returns the number of bytes written before encountering an EAGAIN. The specificity of yielding on EAGAIN is entirely in qemu-coroutine.c. Reviewed-by: NMORITA Kazutaka <morita.kazutaka@lab.ntt.co.jp> Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com>

Fix some bugs in our implementation of the APP_CMD status bit: * the response to an ACMD should have APP_CMD set, not cleared * if an illegal ACMD is sent then the next command should be handled as a normal command This requires that we split "card is expecting an ACMD" from the state of the APP_CMD status bit (the latter indicates both "expecting ACMD" and "that was an ACMD").

Correct how we handle the type B ("cleared on valid command") status bits. In particular, the CURRENT_STATE bits in a response should be the state of the card when it received that command, not the state when it received the preceding command.

Add an extra sd_illegal value to the sd_rsp_type_t enum so that sd_app_command() and sd_normal_command() can tell sd_do_command() that the command was illegal. This is needed so we can do things like reset certain status bits only on receipt of a valid command. For the moment, just use it to pull out the setting of the ILLEGAL_COMMAND status bit into sd_do_command().

Fix bugs in the code determining whether to accept a command when the SD card is locked. Most notably, we had the condition completely reversed, so we would accept all the commands we should refuse and refuse all the commands we should accept. Correct this by refactoring the enormous if () clause into a separate function. We had also missed ACMD42 off the list of commands which are accepted in locked state: add it.

since commit f9b29ca03 included in release 2.31 (docs below say 2.32 but that is not correct) and onwards g_thread_init is deprecated and calling it is not required: http://developer.gnome.org/glib/unstable/glib-Deprecated-Thread-APIs.html#g-thread-init g_thread_init has been deprecated since version 2.32 and should not be used in newly-written code. This function is no longer necessary. The GLib threading system is automatically initialized at the start of your program. Fixes bulid failure when warnings are treated as errors on fedora 17. I only tested the change to vl.c, and copy pasted to the two other locations (couldn't decide if a wrapper for calling g_thread_init is uglier).
