2017-09-05Upgrade OpenJPEG to 2.2.0Nicolas Pena
This CL upgrades OpenJPEG by copying the files from 2.2.0 and then applying patches. Patch files that are no longer relevant are deleted. The relevant ones are applied manually due to changes in formatting in OpenJPEG. Patch 34 is added to account for opj_malloc changes in PDFium.

2017-05-11LibOpenJPEG: undefined shift in opj_t1_dec_clnpassNicolas Pena
bpno_plus_one is used as a parameter bpno for a bunch of methods that calculate 1 << bpno. Thus, use a reduced value when it's large enough to cause undefined shift. bpno_plus_one itself remains unchanged so that the number of calls remains the same Bug: chromium:698526 Change-Id: I40431d41a04f3e2315bd3c80114cd0fcbd2815b4 Reviewed-on: https://pdfium-review.googlesource.com/5310 Reviewed-by: dsinclair <dsinclair@chromium.org> Commit-Queue: Nicolás Peña <npm@chromium.org>
2017-05-09LibOpenJPEG: restrict l_img_comp->prec to avoid undefined shiftNicolas Pena
The 38 value seems arbitrary, and the prec is used in OPJ_INT32 with 1 << (prec - 1). So limit it to be at most 31, and avoid undefined shifts.

2017-05-04Fix undefined shift in opj_get_all_encoding_parametersNicolas Pena
The value 1u << (l_pdx + l_level_no) is only used to calculate a minimum, so skip it when the shift doesn't even fit unsigned integer. Also use the uint min version since all values being considered are unsigned anyways.

2017-03-13LibopenJPEG: Fix some divisions by 0 in pi.cNicolas Pena
The undefined shifts in libopenjpeg are sometimes used as divisors. This CL checks that we are not trying to divide by 0 or mod by 0 in some places in pi.c.

This happens to fix the bug in question but I suspect they still do not have enough checks to prevent undefined shifts.

m_decorrelation_array and m_offset_array can be assigned to l_mct_data, which can be set in opj_j2k_read_mct. In this method, there can be an early true return before allocating m_data but after freeing it.

2017-01-10Fix m_nb_mct_records calculation in opj_j2k_read_mctNicolas Pena
Now we update m_nb_mct_records only when there was a new mct record, and l_mct_data computations all went through. In previous version, the ++l_tcp->m_nb_mcc_records was in the end, without the if. Notice that this is similar to the analoguous in opj_j2k_read_mcc.

2016-03-18openjpeg: Remove unneeded non-standard code.Nico Weber
When building with clang-cl and not passing /FIintrin.h, the __attribute__ defined to nothing, which confuses the compiler (see bug). Since nothing seems to require the __attribute__ redefinition, just remove it.

Fixes 32-bit clang-cl build. These intrinsics require addresses with 16-byte alignment, which doesn't cause issues for 64-bit builds because of allocator alignment. MSVC doesn't recognise the __SSE__, __SSE2__ defines, which is why this problem never surfaced before. R=tsepez@chromium.org BUG=pdfium:433 Review URL: https://codereview.chromium.org/1783813003 .
