2017-08-15mmio-interface: Mark as not user creatablePeter Maydell1-0/+5
The mmio-interface device is not something we want to allow users to create on the command line: * it is intended as an implementation detail of the memory subsystem, which gets created and deleted by that subsystem on demand; it makes no sense to create it by hand on the command line * it uses a pointer property 'host_ptr' which can't be set on the command line Mark the device as not user_creatable to avoid confusion.

We are not providing the required single-copy atomic semantics for the 64-bit operation that is the 32-bit paired load. At the same time, leave the entire 64-bit value in cpu_exclusive_val and stop writing to cpu_exclusive_high. This means that we do not have to re-assemble the 64-bit quantity when it comes time to store. At the same time, drop a redundant temporary and perform all loads directly into the cpu_exclusive_* globals.

2017-08-15nbd-client: Fix regression when server sends garbageEric Blake2-4/+14
When we switched NBD to use coroutines for qemu 2.9 (in particular, commit a12a712a), we introduced a regression: if a server sends us garbage (such as a corrupted magic number), we quit the read loop but do not stop sending further queued commands, resulting in the client hanging when it never reads the response to those additional commands. In qemu 2.8, we properly detected that the server is no longer reliable, and cancelled all existing pending commands with EIO, then tore down the socket so that all further command attempts get EPIPE. Restore the proper behavior of quitting (almost) all communication with a broken server: Once we know we are out of sync or otherwise can't trust the server, we must assume that any further incoming data is unreliable and therefore end all pending commands with EIO, and quit trying to send any further commands. As an exception, we still (try to) send NBD_CMD_DISC to let the server know we are going away (in part, because it is easier to do that than to further refactor nbd_teardown_connection, and in part because it is the only command where we do not have to wait for a reply). Based on a patch by Vladimir Sementsov-Ogievskiy. A malicious server can be created with the following hack, followed by setting NBD_SERVER_DEBUG to a non-zero value in the environment when running qemu-nbd: | --- a/nbd/server.c | +++ b/nbd/server.c | @@ -919,6 +919,17 @@ static int nbd_send_reply(QIOChannel *ioc, NBDReply *reply, Error **errp) | stl_be_p(buf + 4, reply->error); | stq_be_p(buf + 8, reply->handle); | | + static int debug; | + static int count; | + if (!count++) { | + const char *str = getenv("NBD_SERVER_DEBUG"); | + if (str) { | + debug = atoi(str); | + } | + } | + if (debug && !(count % debug)) { | + buf[0] = 0; | + } | return nbd_write(ioc, buf, sizeof(buf), errp); | } Reported-by: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com> Signed-off-by: Eric Blake <eblake@redhat.com> Message-Id: <20170814213426.24681-1-eblake@redhat.com> Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com>

2017-08-15qemu-iotests: step clock after each test iterationStefan Hajnoczi1-0/+4
The 093 throttling test submits twice as many requests as the throttle limit in order to ensure that we reach the limit. The remaining requests are left in-flight at the end of each test iteration. Commit 452589b6b47e8dc6353df257fc803dfc1383bed8 ("vl.c/exit: pause cpus before closing block devices") exposed a hang in 093. This happens because requests are still in flight when QEMU terminates but QEMU_CLOCK_VIRTUAL time is frozen. bdrv_drain_all() hangs forever since throttled requests cannot complete. Step the clock at the end of each test iteration so in-flight requests actually finish. This solves the hang and is cleaner than leaving tests in-flight. Note that this could also be "fixed" by disabling throttling when drives are closed in QEMU. That approach has two issues: 1. We must drain requests before disabling throttling, so the hang cannot be easily avoided! 2. Any time QEMU disables throttling internally there is a chance that malicious users can abuse the code path to bypass throttling limits. Therefore it makes more sense to fix the test case than to modify QEMU.

2017-08-15simpletrace: fix flight recorder --no-header optionStefan Hajnoczi1-6/+18
The simpletrace.py script can pretty-print flight recorder ring buffers. These are not full simpletrace binary trace files but just the end of a trace file. There is no header and the event ID mapping information is often unavailable since the ring buffer may have filled up and discarded event ID mapping records. The simpletrace.stp script that generates ring buffer traces uses the same trace-events-all input file as simpletrace.py. Therefore both scripts have the same global ordering of trace events. A dynamic event ID mapping isn't necessary: just use the trace-events-all file as the reference for how event IDs are numbered. It is now possible to analyze simpletrace.stp ring buffers again using: $ ./simpletrace.py trace-events-all path/to/ring-buffer Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Reviewed-by: Daniel P.

2017-08-15trace: use static event ID mapping in simpletrace.stpStefan Hajnoczi1-29/+2
This is a partial revert of commit 7f1b588f20d027730676e627713ae3bbf6baab04 ("trace: emit name <-> ID mapping in simpletrace header"), which broke the SystemTap flight recorder because event mapping records may not be present in the ring buffer when the trace is analyzed. This means simpletrace.py --no-header does not know the event ID mapping needed to pretty-print the trace. Instead of numbering events dynamically, use a static event ID mapping as dictated by the event order in the trace-events-all file. The simpletrace.py script also uses trace-events-all so the next patch will fix the simpletrace.py --no-header option to take advantage of this knowledge. Cc: Daniel P.

2017-08-11file-posix: Do runtime check for ofd lock APIFam Zheng1-11/+8
It is reported that on Windows Subsystem for Linux, ofd operations fail with -EINVAL. In other words, QEMU binary built with system headers that exports F_OFD_SETLK doesn't necessarily run in an environment that actually supports it: $ qemu-system-aarch64 ... -drive file=test.vhdx,if=none,id=hd0 \ -device virtio-blk-pci,drive=hd0 qemu-system-aarch64: -drive file=test.vhdx,if=none,id=hd0: Failed to unlock byte 100 qemu-system-aarch64: -drive file=test.vhdx,if=none,id=hd0: Failed to unlock byte 100 qemu-system-aarch64: -drive file=test.vhdx,if=none,id=hd0: Failed to lock byte 100 As a matter of fact this is not WSL specific. It can happen when running a QEMU compiled against a newer glibc on an older kernel, such as in a containerized environment. Let's do a runtime check to cope with that.

2017-08-11tests/multiboot: Fix whitespace failureEric Blake1-1/+1
Commit b43671f8 accidentally broke run_test.sh within tests/multiboot; due to a subtle change in whitespace. These two commands produce theh same output (at least, for sane $IFS of space-tab-newline): echo -e "...$@..." echo -e "...$*..." But that's only because echo inserts spaces between multiple arguments (the $@ case), while the $* form gives a single argument to echo with the spaces already present. But when converting to printf %b, there are no automatic spaces between multiple arguments, so we HAVE to use $*. It doesn't help that run_test.sh isn't part of 'make check'.
