2015-11-10qapi: Provide nicer array names in introspectionEric Blake2-5/+10
For the sake of humans reading introspection output, it is nice to have the name of implicit array types be recognizable as arrays of the underlying type. However, while this patch allows humans to skip from a command with return type "[123]" straight to the definition of type "123" without having to first inspect type "[123]", document that this shortcut should not be taken by client apps. This makes the resulting introspection string slightly larger by default (just over 200 bytes), but it's in the noise (less than 0.3% of the overall 70k size of 'query-qmp-capabilities').

2015-11-10qapi: More tests of input arraysEric Blake1-0/+52
Our testsuite had no coverage of empty arrays, nor of what happens when the input does not match the expected type. Useful to have, especially if we start changing the visitor contracts. I did not think it worth duplicating these additions to test-qmp-input-strict; since all strict mode does is add the ability to reject JSON input that has more keys than what the visitor expects, yet the additions in this patch error out earlier than that point regardless of whether strict mode was requested.

2015-11-10qapi: Test failure in middle of array parseEric Blake2-1/+13
Our generated list visitors have the same problem as has been mentioned elsewhere (see commit 2f52e20): they allocate data even on failure. An upcoming patch will correct things to provide saner guarantees, but first we need to expose the behavior in the testsuite to ensure we aren't introducing any memory usage bugs. There are more test cases throughout the test-qmp-input-* tests that already deal with partial allocation; a later commit will clean up all visit_type_FOO(), without marking all of the tests with FIXME at this time.

2015-11-10qapi: More tests of alternate outputEric Blake1-1/+15
The testsuite was only covering that we could output the 'int' branch of an alternate (no additional allocation/cleanup required). Add a test of the 'str' branch, to make sure that things still work even when a branch involves allocation. Update to modern style of g_new0() over g_malloc0() while touching it.

2015-11-10qapi: Simplify error cleanup in test-qmp-*Eric Blake5-35/+31
We have several tests that perform multiple sub-actions that are expected to fail. Asserting that an error occurred, then clearing it up to prepare for the next action, turned into enough boilerplate that it was sometimes forgotten (for example, a number of tests added to test-qmp-input-visitor.c in d88f5fd leaked err). Worse, if an error is not reset to NULL, we risk invalidating later use of that error (passing a non-NULL err into a function is generally a bad idea). Encapsulate the boilerplate into a single helper function error_free_or_abort(), and consistently use it. The new function is added into error.c for use everywhere, although it is anticipated that testsuites will be the main client.

2015-11-09qapi: Simplify non-error testing in test-qmp-*Eric Blake4-135/+53
By using &error_abort, we can avoid a local err variable in situations where we expect success. It also has the nice effect that if the test breaks, the error message from error_abort tends to be nicer than that of g_assert(). This patch has an additional bonus of fixing several call sites that were passing &err to two different functions without checking it in between. In general that is unsafe practice; because if the first function sets an error, the second function could abort() if it tries to set a different error. We got away with it because we were asserting that err was NULL through the entire chain, but switching to &error_abort avoids the questionable practice up front.

2015-11-09qapi: Plug leaks in test-qmp-*Eric Blake3-35/+18
Make valgrind happy with the current state of the tests, so that it is easier to see if future patches introduce new memory problems without being drowned in noise. Many of the leaks were due to calling a second init without tearing down the data from an earlier visit. But since teardown is already idempotent, and we already register teardown as part of input_visitor_test_add(), it is nicer to just make init() safe to call multiple times than it is to have to make all tests call teardown. Another common leak was forgetting to clean up an error object, after testing that an error was raised. Another leak was in test_visitor_in_struct_nested(), failing to clean the base member of UserDefTwo. Cleaning that up left check_and_free_str() as dead code (since using the qapi_free_* takes care of recursion, and we don't want double frees). A final leak was in test_visitor_out_any(), which was reassigning the qobj local variable to a subset of the overall structure needing freeing; it did not result in a use-after-free, but was not cleaning up all the qdict. test-qmp-event and test-qmp-commands were already clean.

2015-11-09qapi: Share test_init code in test-qmp-input*Eric Blake2-51/+46
Rather than duplicate the body of two functions just to decide between qobject_from_jsonv() and qobject_from_json(), exploit the fact that qobject_from_jsonv() intentionally takes 'va_list *' instead of the more common 'va_list', and that qobject_from_json() just calls qobject_from_jsonv(,NULL). For each file, our two existing init functions then become thin wrappers around a new internal function, and future updates to initialization don't have to be duplicated.

2015-11-09qapi: Use generated TestStruct machinery in testsEric Blake6-162/+10
Commit d88f5fd and friends first introduced the various test-qmp-* tests in 2011, with duplicated hand-rolled TestStruct machinery, to make sure the qapi visitor interface was tested. Later, commit 4f193e3 in 2013 added a .json file for further testing use by the files, but without consolidating any of the existing hand-rolled visitors. And with four copies, subtle differences have crept in, between the tests themselves (mainly whitespace differences, but also a question of whether to use NULL or "TestStruct" when calling visit_start_struct()) and from what the generator produces (the hand-rolled versions did not cater to partially-allocated objects, because they did not have a deallocation usage). Of course, just because the visitor interface is tested does not mean it is a sane interface; and future patches will be changing some of the visitor contracts. Rather than having to duplicate the cleanup work in each copy of the TestStruct visitor, and keep each hand-rolled copy in sync with what the generator supplies, we might as well just test what the generator should give us in the first place.

2015-11-09aio: Introduce aio-epoll.cFam Zheng2-1/+188
To minimize code duplication, epoll is hooked into aio-posix's aio_poll() instead of rolling its own. This approach also has both compile-time and run-time switchability. 1) When QEMU starts with a small number of fds in the event loop, ppoll is used. 2) When QEMU starts with a big number of fds, or when more devices are hot plugged, epoll kicks in when the number of fds hits the threshold. 3) Some fds may not support epoll, such as tty based stdio. In this case, it falls back to ppoll. A rough benchmark with scsi-disk on virtio-scsi dataplane (epoll gets enabled from 64 onward). Numbers are in MB/s. =============================================== | master | epoll | | scsi disks # | read randrw | read randrw -------------|----------------|---------------- 1 | 86 36 | 92 45 8 | 87 43 | 86 41 64 | 71 32 | 70 38 128 | 48 24 | 58 31 256 | 37 19 | 57 28 =============================================== To comply with aio_{disable,enable}_external, we always use ppoll when aio_external_disabled() is true.

2015-11-09dataplane: support non-contigious s/gMichael S. Tsirkin1-22/+46
bring_map currently fails if one of the entries it's mapping is contigious in GPA but not HVA address space. Introduce a mapped_len parameter so it can handle this, returning the actual mapped length. This will still fail if there's no space left in the sg, but luckily max queue size in use is currently 256, while max sg size is 1024, so we should be OK even is all entries happen to cross a single DIMM boundary. Won't work well with very small DIMM sizes, unfortunately: e.g. this will fail with 4K DIMMs where a single request might span a large number of DIMMs. Let's hope these are uncommon - at least we are not breaking things.

Not that you can request a >2GiB transaction, but that's why checking for it makes no sense anymore. With the newer 'limit' parameter to prepare_buf, we no longer need a static limit. The maximum limit is still 2GiB, but the limit parameter is set to the current transaction size, which cannot surpass 32MiB (512 * 65536). If the PRDT surpasses the transactional size, then, we'll just carry out the normative underflow handling pathways instead of needing an extra, strange pathway that worries about hitting some logistical cap for the largest sglist we can support -- we'll never even attempt to build one that big anymore.

g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer, for two reasons. One, it catches multiplication overflowing size_t. Two, it returns T * rather than void *, which lets the compiler catch more type errors. This commit only touches allocations with size arguments of the form sizeof(T). Same Coccinelle semantic patch as in commit b45c03f.

2015-11-06bt: fix use of uninitialized variable seqlenPaolo Bonzini1-9/+20
sdp_svc_match, sdp_attr_match and sdp_svc_attr_match read the last argument. The only sensible way to change the code is to make that last argument "len" instead of "seqlen" which is the length of a subsequence in the previous "if" branch. To make the structure of the code clearer, use "else" instead of "else if". Reported by Coverity. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>
2015-11-06hw/dma/pxa2xx: Remove superfluous memsetThomas Huth1-2/+1
g_malloc0 already clears the memory, so no need for the additional memset here. And while we're at it, also convert the g_malloc0 to the preferred g_new0. Signed-off-by: Thomas Huth <thuth@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>
2015-11-06linux-user/syscall: Replace g_malloc0 + memcpy with g_memdupThomas Huth1-2/+1
No need to use g_malloc0 to zero the memory if we memcpy to the whole buffer afterwards anyway. Actually, there is even a function which combines both steps, g_memdup, so let's use this function here instead.
