unix_diag: fix incorrect sign extension in unix_lookup_by_ino
[ Upstream commit b5f0549231ffb025337be5a625b0ff9f52b016f0 ]
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.
Fixes: 5d3cae8bc39d ("unix_diag: Dumping exact socket core")
