Description Matt McCutchen 2009-10-16 07:38:56 UTC
Description of problem:
On my x86_64 system, most of the field values shown for the "newfstatat" system call are incorrect.  For example, "st_size" is a factor of 2^32 larger than what it should be.  This seems to affect only "newfstat", used by find(1), and not more traditional calls such as "lstat" used by stat(1).

Version-Release number of selected component (if applicable):
strace-4.5.18-2.fc11.x86_64

How reproducible:
Always

Steps to Reproduce:
echo -n '1' >size1
echo -n '1234567890' >size10
strace -e trace=newfstatat -v find * -printf ''

Actual results:
newfstatat(AT_FDCWD, "size1", {st_dev=makedev(253, 3), st_ino=1255678337, st_mode=01, st_nlink=0, st_uid=33152, st_gid=500, st_blksize=0, st_blocks=4096, st_size=4294967296, st_atime=1969/12/31-19:00:08, st_mtime=2009/10/16-03:32:17, st_ctime=0}, AT_SYMLINK_NOFOLLOW) = 0
newfstatat(AT_FDCWD, "size10", {st_dev=makedev(253, 3), st_ino=1255678337, st_mode=01, st_nlink=0, st_uid=33152, st_gid=500, st_blksize=0, st_blocks=4096, st_size=42949672960, st_atime=1969/12/31-19:00:08, st_mtime=2009/10/16-03:32:17, st_ctime=0}, AT_SYMLINK_NOFOLLOW) = 0

Expected results:
Data that matches the output of stat(1).

Comment 1 Matt McCutchen 2009-10-16 07:44:38 UTC
I just tested the upstream strace from http://sourceforge.net/projects/strace/ and it has the same problem, but it doesn't seem to have a bug tracker.

Comment 2 Andreas Schwab 2009-10-22 13:01:15 UTC
Fixed in 4.5.19-1.

Comment 3 Matt McCutchen 2009-10-22 14:23:37 UTC
Verified, the problem appears to be gone in strace-4.5.19-1.fc11.x86_64 from Koji.
