2017-11-29[CFI] Enable type generalization for LCMSVlad Tsyrklevich
Control Flow Integrity [1] indirect call checking verifies that function pointers only call valid functions with a matching type signature. This condition can be too strict, a common form of 'abstraction' relies on function pointers being cast to generalize argument pointer types to void*. In LCMS these failures occur because of casts of function pointers called as both _cmsInterpFn16 (cmsInterpFunction.Lerp16) and _cmsOPTeval16Fn (as an argument to _cmsPipelineSetOptimizationParameters) types making it difficult to refactor out easily. Instead, enabling the type generalization build config weakens the type checking performed for CFI-icall to accomodate this common type of casts.

2017-09-27Enable PRINTF_FORMAT for clangDan Sinclair
This ports https://chromium-review.googlesource.com/c/chromium/src/+/599127 from Chromium to PDFium. Because VC++ does not have format-string checking for user-defined functions during normal compiles, because clang-cl had its format-string checking disabled, because some files are only compiled on Windows, and because VC++'s /analyze doesn't build all targets, and because VC++'s format-string checking is more lenient than clang's... 50 warnings about format-string mismatches crept in to Chromium's build. Seven of these were somewhat serious, with four being wchar_t*/char* mismatches because of base::FilePath and the other three being size_t/%d mismatches. Now that all of the mismatches are corrected this change enables PRINTF_FORMAT checking with clang-cl so that these bugs never return.

This CL upgrades LCMS from version 2.6 to 2.8. All changes from LCMS original version 2.8 are stored in patch files: - Patch 0: memory management modifications to use PDFium methods. This was previously not in any patch, so the changes were manually applied. - Patches 1-5: new patch files corresponding to old changes that can be seen in the history, but did not previously have patch files. - Patches 6-25: previous patches (patch numbers shifted by 6). The one for from16-to-8-overflow.patch was deleted as it was already upstream. Some patches did not apply cleanly so their .patch files were modified. - Patch 26: as I just moved files directly, unsupported characters were moved in unchanged, so I had to fix all of them: e with tilde and other characters were replaced to allow compilation on Windows. - Patch 27: Went over the code and re-applied changes that included comments clearly indicating this was Foxit. These changes are all already seen in the initial PDFium commit.

2017-07-27Define SIZEOF_VOIDP and other cleanup in tiffconfNicolas Pena
This CL uses sizeof to calculate sizes in tiffconf. It adds SIZEOF_VOIDP to allow LibTIFF to take codepaths reducing OOMs. Finally, it gets rid of _FX_WIN32_MOBILE_ since it's never defined.

2017-07-20LibTIFF: remove a couple of patchesNicolas Pena
This CL removes two patches that correspond to non-security CF bugs. There are now only a few patches left: two patches to prevent overflow in _TIFFCheckRealloc (overflows here are dangerous as they can cause heap-buffer-overflows), one patch to prevent integer overflows which CF reported as a security issue, and one recent upstream patch (which would be removed in the next LibTIFF upgrade). Next steps: * Figure out how to reproduce the security issue from _TIFFCheckRealloc (samples from the bugs seem to just timeout on asan) and report bug upstream once it's confirmed that a change is needed. * Ditto integer overflow, except it was already reported upstream, so ping upstream once reproduction without the patch is possible again.

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>

2017-05-06core: allow building against system zlibMiklos Vajna
In a way similar to the existing USE_SYSTEM_LIBJPEG. The default is of course still the DEPS-based zlib checkout. Changes in v2: 1) Since Chromium doesn't have //third_party:zlib (AKA a "zlib" target in //third_party/BUILD.GN) all the targets that depended on //third_party:zlib now depend on third_party:zlib, which always points to PDFium's third_party/BUILD.GN. The targets that depended on //third_party:zlib in third_party/BUILD.GN just depend on :zlib instead. 2) Move the zlib bits out of !build_with_chromium block.
