Created attachment 398534 [details] Proposed patch Description of problem: strace incorrectly shows the arguments of fadvise() in 32 bit compat programs Version-Release number of selected component (if applicable): strace-4.5.19-1.fc12.x86_64 How reproducible: Always Steps to Reproduce: 1. Find a program that calls posix_fadvise(2). My sample program calls posix_fadvise(2) like this: posix_fadvise(fd, 0, 0, POSIX_FADV_RANDOM); posix_fadvise(fd, 5, 7, POSIX_FADV_SEQUENTIAL); posix_fadvise64(fd, 0, 0, POSIX_FADV_RANDOM); posix_fadvise64(fd, 5, 7, POSIX_FADV_SEQUENTIAL); (The second and third arguments are only to illustrate the problem, they don't actually have any useful meaning.) 2. Compile it as a 32 bit application 3. Run under strace. Actual results: fadvise64(3, 0, 0, POSIX_FADV_NORMAL) = 0 fadvise64(3, 5, 0, 0x7 /* POSIX_FADV_??? */) = 0 fadvise64_64(3, 0, 0, POSIX_FADV_NORMAL) = 0 fadvise64_64(3, 5, 0, 0x7 /* POSIX_FADV_??? */) = 0 Expected results: fadvise64(3, 0, 0, POSIX_FADV_RANDOM) = 0 fadvise64(3, 5, 7, POSIX_FADV_SEQUENTIAL) = 0 fadvise64_64(3, 0, 0, POSIX_FADV_RANDOM) = 0 fadvise64_64(3, 5, 7, POSIX_FADV_SEQUENTIAL) = 0 Additional info: The attached patch fixes this problem, it is based on: commit b5600fc3df0453ba11f254a9b49add3ffbec9733 Author: Andreas Schwab <schwab> Date: Wed Nov 4 17:08:34 2009 +0100 (The changes are merely needed to make it apply cleanly.)
