2017-01-12libqtest: handle zero length memwrite/memreadGreg Kurz2-1/+13
Some recently added tests pass a zero length to qtest_memwrite(). Unfortunately, the qtest protocol doesn't implement an on-the-wire syntax for zero-length writes and the current code happily sends garbage to QEMU. This causes intermittent failures. It isn't worth the pain to enhance the protocol, so this patch simply fixes the issue by "just return, doing nothing". The same fix is applied to qtest_memread() since the issue also exists in the QEMU part of the "memread" command.

2017-01-10curses: Fix compiler warnings (Mingw-w64 redefinition of macro KEY_EVENT)Stefan Weil2-1/+3
For builds with Mingw-w64 as it is included in Cygwin, there are two header files which define KEY_EVENT with different values. This results in lots of compiler warnings like this one: CC vl.o In file included from /qemu/include/ui/console.h:340:0, from /qemu/vl.c:76: /usr/i686-w64-mingw32/sys-root/mingw/include/curses.h:1522:0: warning: "KEY_EVENT" redefined #define KEY_EVENT 0633 /* We were interrupted by an event */ In file included from /usr/share/mingw-w64/include/windows.h:74:0, from /usr/share/mingw-w64/include/winsock2.h:23, from /qemu/include/sysemu/os-win32.h:29, from /qemu/include/qemu/osdep.h:100, from /qemu/vl.c:24: /usr/share/mingw-w64/include/wincon.h:101:0: note: this is the location of the previous definition #define KEY_EVENT 0x1 QEMU only uses the KEY_EVENT macro from wincon.h. Therefore we can undefine the macro coming from curses.h. The explicit include statement for curses.h in ui/curses.c is not needed and was removed. Those two modifications fix the redefinition warnings.

2017-01-10ui/vnc: Fix problem with sending too many bytes as server nameThomas Huth1-2/+6
If the buffer is not big enough, snprintf() does not return the number of bytes that have been written to the buffer, but the number of bytes that would be needed for writing the whole string. By using this value for the following vnc_write() calls, we send some junk at the end of the name in case the qemu_name is longer than 1017 bytes, which could confuse the VNC clients. Fix this by adding an additional size check here.

That reduces DSDT by 910 bytes when memory hotplug isn't enabled. While doing so drop intermediate variables/arguments passing around ACPI_MEMORY_HOTPLUG_IO_LEN and making it local to memory_hotplug.c, hardcoding it there as it can't change. Also don't pass around ACPI_MEMORY_HOTPLUG_BASE through intermediate variables/arguments where it's not needed. Instead initialize in module static variable when MMIO region is mapped and use that within memory_hotplug.c whenever it's required. That way MMIO base specified only at one place and AML with MMIO would always use the same value. Signed-off-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Michael S.
