Revision b5f0549231ffb025337be5a625b0ff9f52b016f0 authored by Dmitry V. Levin on 19 February 2016, 01:27:48 UTC, committed by David S. Miller on 20 February 2016, 04:49:23 UTC
The value passed by unix_diag_get_exact to unix_lookup_by_ino has type
__u32, but unix_lookup_by_ino's argument ino has type int, which is not
a problem yet.
However, when ino is compared with sock_i_ino return value of type
unsigned long, ino is sign extended to signed long, and this results
to incorrect comparison on 64-bit architectures for inode numbers
greater than INT_MAX.

This bug was found by strace test suite.
