2014-11-17target-cris/translate.c: fix out of bounds readzhanghailiang
In function t_gen_mov_TN_preg and t_gen_mov_preg_TN, The begin check about the validity of in-parameter 'r' is useless. We still access cpu_PR[r] in the follow code if it is invalid. Which will be an out-of-bounds read error. Fix it by using assert() to ensure it is valid before using it.

2014-11-13QMP/input-send-event: make console parameter optionalAmos Kong
The 'QemuConsole' is the input source for handler, we share some input handlers to process the input events from different QemuConsole. Normally we only have one set of keyboard, mouse, usbtablet, etc. The devices have different mask, it's fine to just checking mask to insure that the handler has the ability to process the event. I saw we try to bind console to handler in usb/dev-hid.c, but display always isn't available at that time. If we have multiseat setup (as Gerd said), we only have 'problem' in this case. Actually event from different devices have the same effect for system, it's fine to always use the first available handler without caring about the console. For send-key command, we just pass a NULL for console parameter in calling qemu_input_event_send_key(NULL, ..), but 'input-send-event' needs to care more devices. Conclusion: Generally assigning the special console is meanless, and we can't directly remove the QMP parameter for compatibility. So we can make the parameter optional. The parameter might be useful for some special condition: we have multiple devices without binding console and they all have the ability(mask) to process events, and we don't want to use the first one.

Without the whitelist entries, qemu-kvm -sandbox on fails immediately. In my tests fadvise64() is called 50--51 times per VM run. That number seems independent of the duration of the run. fallocate(), inotify_init1(), inotify_add_watch() are called once each. Accordingly, they are added to the whitelist at a very low priority.

This is a simple patch to change the type of old_env from jmp_buf to sigjmp_buf. old_env is used by sigsetjmp and as such should be a sigjmp_buf. This fixes a stack_chk fail in a OSX 32bit build. Since at least on OSX sigjmp_buf is four bytes larger then a jmpbuf, resulting in an overflow in sigsetjmp. Due to variable reordering this overwrites the stack cookie.

2014-11-11linux-user: Fix up timer id handlingAlexander Graf
When creating a timer handle, we give the timer id a special magic offset of 0xcafe0000. However, we never mask that offset out of the timer id before we start using it to dereference our timer array. So we always end up aborting timer operations because the timer id is out of bounds. This was not an issue before my patch e52a99f756e ("linux-user: Simplify timerid checks on g_posix_timers range") because before we would blindly mask anything above the first 16 bits. This patch simplifies the code around timer id creation by introducing a proper target_timer_id typedef that is s32, just like Linux has it. It also changes the magic offset to a value that makes all timer ids be positive.

2014-11-11gdbstub: Add a missing case of signal number translation in gdbstubMartin Simmons
While using qemu with gdb "target remote" to debug an application that uses fork and exec, the qemu process receives SIGSTOP every time the forked process terminates (sending SIGCHLD). This is caused by a missing call to gdb_signal_to_target in gdbstub.c, which is fixed by this patch: Signed-off-by: Martin Simmons <martin@lispworks.com> Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>
