Thanks for the investigation, Charles-François. I'm closing as invalid, then.

[issue11341] test_os fails

2011-02-28 Thread Charles-Francois Natali 

Charles-Francois Natali  added the comment:

Alright, digging a little further, it's a kernel bug introduced by this commit:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=4a3956c790290efeb647bbb0c3a90476bb57800e

Note that this should only affect 64-bit systems (comparison between
long long int and unsigned long int). Also, it's only present since
2.6.37.

It has been fixed by this commit:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=cccb5a1e698535fa5a734ffe21c7061c97f8d8c5

Just checked the source code:
in fs/read_write.c:do_sendfile

 841 pos = *ppos;
 842 if (unlikely(pos + count > max)) {
 843 retval = -EOVERFLOW;
 844 if (pos >= max)
 845 goto fput_out;
 846 count = max - pos;
 847 }

and 

 869 if (*ppos > max)
 870 retval = -EOVERFLOW;

Errno 75 is EOVERFLOW here (Linux), which doesn't seem to be mentioned in 
sendfile's man page.
Can you describe your system? (CPU architecture, bitness, endianness, 
glibc/kernel version, etc.)
