The eventfd2 syscall was added to the Linux kernel in mid 2007, for Linux 2.6.22, but exp-ptrcheck has no handler for it today. Section 11.6, Limitations, of the valgrind manual http://valgrind.org/docs/manual/valgrind_manual.pdf: Heap checks: Ptrcheck needs to "understand" which system calls return pointers and which don’t. Many, but not all system calls are handled. If an unhandled one is encountered, Ptrcheck will abort. Fortunately, adding support for a new syscall is very easy. So knock on the door of a valgrind developer, and ask nicely. The best way to do so is to file a polite, complete, bug report. Or, get the source code and do it yourself. In the meantime, one possible work-around is to change the usage of the app so that eventfd2() is not used. -- ------------------------------------------------------------------------------ Enable your software for Intel(R) Active Management Technology to meet the growing manageability and security demands of your customers.
