[-- Attachment #1 --] The latest change to the mmap code breaks the LTP tests on -CURRENT/amd64. The cause of the failure is that mmap is returning with MAP_FAILED. The LTP tests use: bad_addr = mmap(0, 1, PROT_NONE, MAP_PRIVATE|MAP_ANONYMOUS, 0, 0); to check fuctions to see if they can detect a bad address. Runnin the ltp_mmaptest.c returns with the MAP_FAILED error. I have also included the debug output the when linuolator when running this test program. $ uname -a FreeBSD hp010 7.0-CURRENT FreeBSD 7.0-CURRENT #1: Sat Feb 24 00:44:00 CST 2007 swhetzel@hp010:/usr/src/7x/sys-p4/amd64/compile/GENERIC.debug amd64 $ Scot -- DISCLAIMER: No electrons were mamed while sending this message.
