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. Fixes: 5d3cae8bc39d ("unix_diag: Dumping exact socket core") Signed-off-by: Dmitry V.
