Hi all, Speaking about warnings, we're seeing the following warnings when building LLVM/Clang on FreeBSD/amd64. When using GCC: http://amd64-clang-bot.qat.freebsd.org:8010/builders/freebsd-clang-amd64/builds/20/steps/compile-llvm.1/logs/warnings When using Clang: http://amd64-clang-bot.qat.freebsd.org:8010/builders/freebsd-clang-amd64/builds/20/steps/compile-llvm.2/logs/warnings -- Ed Schouten <ed at 80386.nl> WWW: http://80386.nl/ ------...

Dear all, When I tried to compile LLVM, I found these annoying warnings. I actually found several other, but this patch deals with the trivial ones Regards, Rizky Herucakra -------------- next part -------------- An HTML attachment was scrubbed...

...stions. For kernel crypto core, each cipher request should be freed by skcipher_request_free(): zeroize and free request data structure. I need to use kzfree() for key as well.

...ving member of the team. Mark had spent many long hours refactoring and documenting the portbuild software to ensure that pointyhat services could be restored. After a security review, redports.org was turned back on, restoring Tinderbox services to contributors, along with post commit QATs. In addition, pointyhat infrastructure had also undergone a review and work begain on restoring the package build system. Erwin Lansing (erwin) and Martin Wilke (miwi) took on the principle roles of getting the portbuild software installed and running on pointyhat. As a result of a...
