Dmitry Vyukov	7c63340586	tsan: fix handling of dup2 Previously tsan modelled dup2(oldfd, newfd) as write on newfd. We hit several cases where the write lead to false positives: 1. Some software dups a closed pipe in place of a socket before closing the socket (to prevent races actually). 2. Some daemons dup /dev/null in place of stdin/stdout. On the other hand we have not seen cases when write here catches real bugs. So model dup2 as read on newfd instead. llvm-svn: 240687	2015-06-25 20:32:04 +00:00
