Even Rouault 28094e1ebf opj_tcd_mct_decode(): avoid heap buffer overflow when components have not the same number of resolutions. Also fixes an issue with subtile decoding. Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=3331. Credit to OSS Fuzz 2017-09-08 10:56:49 +02:00

Even Rouault 51a1dcaa6e Avoid malloc poisoning issue when including <pthread.h> of uclibc (#1013) 2017-09-07 17:52:59 +02:00
Even Rouault cc893a4ebf opj_tcd_mct_decode(): fix checks to verify MCT can be done safely. Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=3305 (master only) 2017-09-07 15:32:54 +02:00
Even Rouault c67e1cd73f Fix invalid access out of bounds, and bad behaviour, when calling repeatdly opj_get_decoded_tile() on an image with a color palette 2017-09-06 17:33:38 +02:00
Even Rouault 297f202104 Fix 2.2.0 regression when reading codestream with reperated calls to opj_get_decoded_tile() where tile parts of a same tile are not consecutive 
This check was introduced per #939, but relied on the incorrect assumption
we decode all the tile parts of all tiles.
 2017-09-06 16:49:28 +02:00
Even Rouault 003759a482 Fix null pointer dereference on partial tile decoding when they are empty. Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=3297 (master only) 2017-09-06 15:59:19 +02:00
Even Rouault e656822f92 Add knownfailures-Ubuntu12.04-gcc4.6.3-x86_64-Release-3rdP.txt 
For some reason, the OPJ_CI_ARCH=x86_64 OPJ_CI_BUILD_CONFIGURATION=Release OPJ_NUM_THREADS=2
configuration fails once PR1010 has been merged in master
( https://travis-ci.org/uclouvain/openjpeg/jobs/272219011 ) whereas (almost) the same
code in my branch didn't fail per https://travis-ci.org/rouault/openjpeg/jobs/271738113

The errors we get are the same as with the other x86_64 compilers, so nothing alarming here.

Even Rouault b428b8c7e7 opj_tcd_rateallocate(): make sure to use all passes for a lossless layer (#1009) 
And save a useless loop, which should be a tiny faster.
 2017-09-01 20:02:09 +02:00
Even Rouault 7aa071aa27 opj_j2k_setup_encoder(): emit warnings if tcp_rates are not decreasing or tcp_distoratio are not increasing (#1009) 2017-09-01 19:49:01 +02:00

Even Rouault 09929bb615 opj_compress help: revert 3257261776 and indicate 1 again as being the value to get lossless for -r. In opj_j2k_setup_encoder(), make sure that ll rates[] <= 1.0 are set to 0. Document 0 as being lossless for -q / tcp_distoratio (#1009) 2017-09-01 19:16:35 +02:00

Even Rouault 82a43d8035 Optimize opj_dwt_decode_partial_1() when cas == 0 2017-09-01 16:30:54 +02:00
Even Rouault 1644665a91 opj_j2k_update_image_data(): avoid zero-ing the buffer if not needed 2017-09-01 16:30:52 +02:00
Even Rouault b2cc8f7f81 Optimize reading/write into sparse array 2017-09-01 16:30:50 +02:00
Even Rouault 0ae3cba340 Allow several repeated calls to opj_set_decode_area() and opj_decode() for single-tiled images 
* Only works for single-tiled images --> will error out cleanly, as currently
  in other cases
* Save re-reading the codestream for the tile, and re-use code-blocks of the
  previous decoding pass.
* Future improvements might involve improving opj_decompress, and the image writing logic,
  to use this strategy.
 2017-09-01 16:30:48 +02:00
Even Rouault 5d07d463fd opj_j2k_decode_tiles(): apply whole single tile image decoding optimization to reading at reduced resolution as well 2017-09-01 16:30:45 +02:00
Even Rouault 98b9310361 Various changes to allow tile buffers of more than 4giga pixels 
Untested though, since that means a tile buffer of at least 16 GB. So
there might be places where uint32 overflow on multiplication still occur...
 2017-09-01 16:30:44 +02:00
Even Rouault 008a12d4fc TCD: allow tile buffer to be greater than 4GB on 64 bit hosts (but number of pixels must remain under 4 billion) 2017-09-01 16:30:41 +02:00
Even Rouault d1299d9670 Fix compiler warning in release mode 2017-09-01 16:30:39 +02:00
Even Rouault d5153ba404 Remove limitation that prevents from opening images bigger than 4 billion pixels 
However the intermediate buffer for decoding must still be smaller than 4
billion pixels, so this is useful for decoding at a lower resolution level,
or subtile decoding.
 2017-09-01 16:30:37 +02:00
Even Rouault c37e360a51 opj_tcd_init_tile(): fix typo on overflow detection condition (introduced in previous commit) 2017-09-01 16:30:35 +02:00
Even Rouault eee5104a88 opj_dwt_decode_partial_tile(): avoid undefined behaviour in lifting operation by properly initializing working buffer 2017-09-01 16:30:32 +02:00
Even Rouault f9e9942330 Sub-tile decoding: only allocate tile component buffer of the needed dimension 
Instead of being the full tile size.

* Use a sparse array mechanism to store code-blocks and intermediate stages of
  IDWT.
* IDWT, DC level shift and MCT stages are done just on that smaller array.
* Improve copy of tile component array to final image, by saving an intermediate
  buffer.
* For full-tile decoding at reduced resolution, only allocate the tile buffer to
  the reduced size, instead of the full-resolution size.
