2017-06-07net/rocker: Cleanup the useless return value checkMao Zhongyi
None of pci_dma_read()'s callers check the return value except rocker. There is no need to check it because it always return 0. So the check work is useless. Remove it entirely.

2017-06-04qapi: Fix some QMP documentation regressionsEric Blake
In the process of getting rid of docs/qmp-commands.txt, we managed to regress on some of the text that changed after the point where the move was first branched and when the move actually occurred. For example, commit 3282eca for blockdev-snapshot re-added the extra "options" layer which had been cleaned up in commit 0153d2f. This clears up all regressions identified over the range 02b351d..bd6092e: https://lists.gnu.org/archive/html/qemu-devel/2017-05/msg05127.html as well as a cleanup to x-blockdev-remove-medium to prefer 'id' over 'device' (matching the cleanup for 'eject').

NetBSD ships with traditional BSD curses with compatibility with ncurses. qemu works nicely with the basesystem version of curses(3) from NetBSD. The only mismatch between curses(3) and ncurses is the lack of curses_version() in the NetBSD version. This function is used solely in the configure script, therefore eliminate it from the curses(3) detection. With this change applied, configure detects correctly curses frontend.

2017-06-02virtio-serial: fix segfault on disconnectStefan Hajnoczi
Since commit d4c19cdeeb2f1e474bc426a6da261f1d7346eb5b ("virtio-serial: add missing virtio_detach_element() call") the following commands may cause QEMU to segfault: $ qemu -M accel=kvm -cpu host -m 1G \ -drive if=virtio,file=test.img,format=raw \ -device virtio-serial-pci,id=virtio-serial0 \ -chardev socket,id=channel1,path=/tmp/chardev.sock,server,nowait \ -device virtserialport,chardev=channel1,bus=virtio-serial0.0,id=port1 $ nc -U /tmp/chardev.sock ^C (guest)$ cat /dev/zero >/dev/vport0p1 The segfault is non-deterministic: if the event loop notices the socket has been closed then there is no crash. The disconnect has to happen right before QEMU attempts to write data to the socket. The backtrace is as follows: Thread 1 "qemu-system-x86" received signal SIGSEGV, Segmentation fault. 0x00005555557e0698 in do_flush_queued_data (port=0x5555582cedf0, vq=0x7fffcc854290, vdev=0x55555807b1d0) at hw/char/virtio-serial-bus.c:180 180 for (i = port->iov_idx; i < port->elem->out_num; i++) { #1 0x000055555580d363 in virtio_queue_notify_vq (vq=0x7fffcc854290) at hw/virtio/virtio.c:1524 #2 0x000055555580d363 in virtio_queue_host_notifier_read (n=0x7fffcc8542f8) at hw/virtio/virtio.c:2430 #3 0x0000555555b3482c in aio_dispatch_handlers (ctx=ctx@entry=0x5555566b8c80) at util/aio-posix.c:399 #4 0x0000555555b350d8 in aio_dispatch (ctx=0x5555566b8c80) at util/aio-posix.c:430 #5 0x0000555555b3212e in aio_ctx_dispatch (source=<optimized out>, callback=<optimized out>, user_data=<optimized out>) at util/async.c:261 #6 0x00007fffde71de52 in g_main_context_dispatch () at /lib64/libglib-2.0.so.0 #7 0x0000555555b34353 in glib_pollfds_poll () at util/main-loop.c:213 #8 0x0000555555b34353 in os_host_main_loop_wait (timeout=<optimized out>) at util/main-loop.c:261 #9 0x0000555555b34353 in main_loop_wait (nonblocking=<optimized out>) at util/main-loop.c:517 #10 0x0000555555773207 in main_loop () at vl.c:1917 #11 0x0000555555773207 in main (argc=<optimized out>, argv=<optimized out>, envp=<optimized out>) at vl.c:4751 The do_flush_queued_data() function does not anticipate chardev close events during vsc->have_data().

Virtio serial device controls the lifetime of virtio-serial-bus and virtio-serial-bus links back to the device via its hotplug-handler property. This extra ref-count prevents the device from getting finalized, leaving the VirtIODevice memory listener registered and leading to use-after-free later on.

Add missing support for "preallocation=falloc" to the Gluster block driver. This change bases its logic on that of block/file-posix.c and removed the gluster_supports_zerofill() and qemu_gluster_zerofill() functions in favour of #ifdef checks in an easy to read switch-statement. Both glfs_zerofill() and glfs_fallocate() have been introduced with GlusterFS 3.5.0 (pkg-config glusterfs-api = 6). A #define for the availability of glfs_fallocate() has been added to ./configure.

2017-06-02aspeed: add some I2C devices to the Aspeed machinesCédric Le Goater

2017-06-02aspeed/i2c: introduce a state machineCédric Le Goater
The Aspeed I2C controller maintains a state machine in the command register, which is mostly used for debug. Let's start adding a few states to handle abnormal STOP commands. Today, the model uses the busy status of the bus as a condition to do so but it is not precise enough. Also remove the ABNORMAL bit for failing TX commands. This is incorrect with respect to the specs.

2017-06-02aspeed/i2c: improve command handlingCédric Le Goater
Multiple I2C commands can be fired simultaneously and the controller execute the commands following these priorities: (1) Master Start Command (2) Master Transmit Command (3) Slave Transmit Command or Master Receive Command (4) Master Stop Command The current code is incorrect with respect to the above sequence and needs to be reworked to handle each individual command.

2017-06-02arm: Implement HFNMIENA support for M profile MPUPeter Maydell
Implement HFNMIENA support for the M profile MPU. This bit controls whether the MPU is treated as enabled when executing at execution priorities of less than zero (in NMI, HardFault or with the FAULTMASK bit set). Doing this requires us to use a different MMU index for "running at execution priority < 0", because we will have different access permissions for that case versus the normal case.

2017-06-02arm: add MPU support to M profile CPUsMichael Davidsaver
The M series MPU is almost the same as the already implemented R profile MPU (v7 PMSA). So all we need to implement here is the MPU register interface in the system register space. This implementation has the same restriction as the R profile MPU that it doesn't permit regions to be sized down smaller than 1K. We also do not yet implement support for MPU_CTRL.HFNMIENA; this bit should if zero disable use of the MPU when running HardFault, NMI or with FAULTMASK set to 1 (ie at an execution priority of less than zero) -- if the MPU is enabled we don't treat these cases any differently.

2017-06-02armv7m: Classify faults as MemManage or BusFaultMichael Davidsaver
General logic is that operations stopped by the MPU are MemManage, and those which go through the MPU and are caught by the unassigned handle are BusFault. Distinguish these by looking at the exception.fsr values, and set the CFSR bits and (if appropriate) fill in the BFAR or MMFAR with the exception address.

2017-06-02arm: All M profile cores are PMSAPeter Maydell
All M profile CPUs are PMSA, so set the feature bit. (We haven't actually implemented the M profile MPU register interface yet, but setting this feature bit gives us closer to correct behaviour for the MPU-disabled case.)

2017-06-02armv7m: Implement M profile default memory mapMichael Davidsaver
Add support for the M profile default memory map which is used if the MPU is not present or disabled. The main differences in behaviour from implementing this correctly are that we set the PAGE_EXEC attribute on the right regions of memory, such that device regions are not executable.
