2015-10-06invalid_file_test: loosen error check w/tile-threadingJames Zern
The serial decode check is too strict for tile-threaded decoding as there is no guarantee on the decode order nor which specific error will take precedence. Currently a tile-level error is not forwarded so the frame will simply be marked corrupt. Change-Id: I51cf1e39e44bedeac93746154b36a4ccb2f059b1

2015-07-17Correctly report "Unsupported bitstream profile"Yaowu Xu
For vp9 decoder build without profile 2 and profile 3 support, this commit changes to report error "Unsupported bitstream profile" for input streams in profile 2 or 3, rather than other misleading error information. In addition, one of the invalid files in unit tests is actually coded profile 2, this commit makes it tested only when the decoder is built with vp9-highbitdepth. This fixes issue #1028.

2015-02-05vp9: fix segfault w/corrupt data post frame-parallel mergeJames Zern
cm->frame_bufs[].idx values were made consistent in: 61c5e94 Use -1 consistently as invalid buffer idx update the initialization in swap_frame_buffers() to match. additionally: - remove some shadowed variables in the former and marked them volatile Change-Id: Ie3f9636c405bd822112bb56bd22d28024ae98909
2014-11-06Modify the frame context memory deallocationYunqing Wang
This patch was to fix the vpxdec fuzzing3 test failure. When an error occurs, setjmp() is invoked, which calls the decoder removing routine. In multiple thread situation, other threads could try to access the frame context memory that is already deallocated, thus causing a segfault. An invalid unit test was added for this issue.

2014-09-09vp9: wait for key/intra-only frame after corruptionJames Zern
don't bother decoding any further after receiving an earlier decode error until a key/intra-only frame is encountered. Change-Id: I381917b70d7a9e6f8d6de42e3d181bb113a4cec4

2014-09-04vp9: correct context buffer resize checkJames Zern
allocations within vp9_alloc_context_buffers() rely on mi_rows/mi_cols individually, use those to determine whether to realloc rather than stride and stride * rows. this fixes a crash with some fuzzed files for invalid accesses into last_frame_seg_map and above_context. Change-Id: I7b9f40dcf170d443890f3bd2acd285507943c7d4
2014-09-04vp9: fail decode if block/frame refs are corruptJames Zern
proceeding using a corrupt (incompletely decoded) frame reference may lead to incorrect assumptions about allocation sizes leading to a crash. Change-Id: I76e74f2e1be127c2e2c7e1174bb3307497dfd23d
2014-08-29vp9: fix m/t loop filter invalid freeJames Zern
store the number of allocated rows in VP9LfSync, the calculated values can not be relied on when dealing with corrupt material. Change-Id: I13b8bcec9738c299a71df726772ab7ac05511e5b
2014-08-27vp9: fix crash in inline loopfilter w/corrupt fileJames Zern
attempting to decode a frame after the previous frame failed has the potential of interrupting an earlier loop filter task Change-Id: I6f2b1ddcdf5b89c3e2ee8caf5289dada2a087d66
2014-08-27vp9: fix crash in mt loopfilter w/corrupt fileJames Zern
if the first frame was corrupt and loop filter not called, the next call would assume the necessary allocations had been done and segfault when accessing a NULL pointer Change-Id: Ib6ef505e5c594e6f0fe65ab0700172bcf06b92a6

2014-07-17Separates profile 2 into 2 profiles 2 and 3Deb Mukherjee
Separates HBD profile int two profiles (2 and 3) consistent with the highbitdepth branch. This patch is ported from the original highbitdepth branch patch: https://gerrit.chromium.org/gerrit/#/c/70460/ Two of the invalid file tests needed to be updated.

2014-07-14invalid_file_test: add an operator<< for DecodeParamJames Zern
Improves the --gtest_list_tests output and avoids a valgrind warning in gtest's testing::internal2::PrintBytesInObjectTo() due to padding in the structure. old: VP9/InvalidFileTest. ReturnCode/0 # GetParam() = (0x9d5308, 16-byte object <01-00 00-00 00-00 00-00 37-02 73-00 00-00 00-00>) new: VP9/InvalidFileTest. ReturnCode/0 # GetParam() = (0x9d5308, threads: 1 file: invalid-vp90-01-v2.webm) Change-Id: Ifb9c66fba2e72272bd591a3f6273aeb6bda6af4a
2014-07-12invalid_file_test: convert test param from tuple to structJames Zern
fixes visual studio 9 + apple clang builds where the template type is interpreted as char[] rather than const char*: ::f1_' : cannot specify explicit initializer for arrays error: array initializer must be an initializer list or string literal Change-Id: I27286ce341b2f7a09b6202caffd6b72f64fd2234

2014-06-27Better validation of invalid filesJim Bankoski
This patch checks that a decoder never tries to reference frame that's outside the range of 2x to 1/16th the size of this frame. Any attempt to do so causes a failure. Change-Id: I5c98fa7bb95ac4f29146f29dd92b62fe96164e4c

2014-06-23error check vp9 superframe parsingJim Bankoski
This patch insures that the last byte of a chunk that contains a valid superframe marker byte, actually has a proper superframe index. If not it returns an error. As part of doing that the file : vp90-2-15-fuzz-flicker.webm now fails to decode properly and moves to the invalid file test from the test vector suite. Change-Id: I5f1da7eb37282ec0c6394df5c73251a2df9c1744
2014-06-20Fix bug in error handling that causes segfaultJim Bankoski
See: https://code.google.com/p/chromium/issues/detail?id=362697 The code properly catches an invalid stream but seg faults instead of returning an error due to a buffer not having been initialized. This code fixes that. Change-Id: I695595e742cb08807e1dfb2f00bc097b3eae3a9b
2014-06-20Validate error checking code in decoder.Jim Bankoski
This patch adds a mechanism for insuring error checking on invalid files by creating a unit test that runs the decoder and tests that the error code matches what's expected on each frame in the decoder. Disabled for now as this unit test will segfault with existing code. Change-Id: I896f9686d9ebcbf027426933adfbea7b8c5d956e
