2021-01-22tcg: update the cpu running flag in cpu_exec_step_atomicDouglas Crosher
The cpu_exec_step_atomic() function is called with the cpu->running clear and proceeds to run target code without setting this flag. If this target code generates an exception then handle_cpu_signal() will unnecessarily abort. For example if atomic code generates a memory protection fault. This patch at least sets and clears this running flag, and adds some assertions to help detect other cases.

2021-01-21tests/tcg/s390x: Fix EXRL testsDavid Hildenbrand
The current EXRL tests crash on real machines: we must not use r0 as a base register for trt/trtr, otherwise the content gets ignored. Also, we must not use r0 for exrl, otherwise it gets ignored. Let's use the "a" constraint so we get a general purpose register != r0. For op2, we can simply specify a memory operand directly via "Q" (Memory reference without index register and with short displacement).

2021-01-21s390x/tcg: Don't ignore content in r0 when not specified via "b" or "x"David Hildenbrand
Using get_address() with register identifiers comming from an "r" field is wrong: if the "r" field designates "r0", we don't read the content and instead assume 0 - which should only be applied when the register was specified via "b" or "x". PoP 5-11 "Operand-Address Generation": "A zero in any of the B1, B2, X2, B3, or B4 fields indicates the absence of the corresponding address component. For the absent component, a zero is used in forming the intermediate sum, regardless of the contents of general register 0. A displacement of zero has no special significance." This BUG became visible for CSPG as generated by LLVM-12 in the upstream Linux kernel (v5.11-rc2), used while creating the linear mapping in vmem_map_init(): Trying to store to address 0 results in a Low Address Protection exception. Debugging this was more complicated than it could have been: The program interrupt handler in the kernel will try to crash the kernel: doing so, it will enable DAT. As the linear mapping is not created yet (asce=0), we run into an addressing exception while tring to walk non-existant DAT tables, resulting in a program exception loop. This allows for booting upstream Linux kernels compiled by clang-12. Most of these cases seem to be broken forever.

2021-01-20nbd/server: Quiesce coroutines on context switchSergio Lopez
When switching between AIO contexts we need to me make sure that both recv_coroutine and send_coroutine are not scheduled to run. Otherwise, QEMU may crash while attaching the new context with an error like this one: aio_co_schedule: Co-routine was already scheduled in 'aio_co_schedule' To achieve this we need a local implementation of 'qio_channel_readv_all_eof' named 'nbd_read_eof' (a trick already done by 'nbd/client.c') that allows us to interrupt the operation and to know when recv_coroutine is yielding. With this in place, we delegate detaching the AIO context to the owning context with a BH ('nbd_aio_detach_bh') scheduled using 'aio_wait_bh_oneshot'. This BH signals that we need to quiesce the channel by setting 'client->quiescing' to 'true', and either waits for the coroutine to finish using AIO_WAIT_WHILE or, if it's yielding in 'nbd_read_eof', actively enters the coroutine to interrupt it.

2021-01-20qemu-nbd: Fix a memleak in nbd_client_thread()Alex Chen
When the qio_channel_socket_connect_sync() fails we should goto 'out_socket' label to free the 'sioc' instead of goto 'out' label. In addition, there's a lot of redundant code in the successful branch and the error branch, optimize it.
