We ran the Connectathon testsuites on Solaris 7/Sparc client, Solaris 7/x86 client and Linux client. <P> The Solaris test results are in Appendix <A HREF="node21.html#solaris">A</A>. They showed that the Linux kernel-space NFS server passed all the tests serving Solaris clients. In the Linux test result in Appendix <A HREF="node24.html#linux">B</A>, there is a warning: <P> <PRE> Test #13 - Check locking and mmap semantics. Parent: 13.0 - F_TLOCK [ ffe, ENDING] PASSED. Parent: 13.1 - mmap [ 0, 1000] WARNING! Parent: **** Expected EAGAIN, returned success... </PRE> <P> From the comment in the test: <P> <PRE> /* * Can a file be locked and mapped at same time? It's * potentially safe if the whole file is locked, or if the * locked region is page-aligned. Otherwise, there is a * race condition between two clients that lock disjoint * regions of the same page. So for this test we * deliberately lock a region that is not * page-aligned--that should cause the mmap to fail. But if * it doesn't, that's arguably not an interoperability * problem, so make it a warning, not a fatal error. */ </PRE> <P> This warning is due to the Linux NFS client implementation. It doesn't affect the interoperability of the Linux NFS server. <P> <BR><HR> <ADDRESS> <I>H.J. Lu</I> <BR><I>1999-08-15</I> </ADDRESS> </BODY> </HTML>
