Linux ino_t has aliasing issues when truncated to 32b
Registered by
Jeff Johnson
RPMTAG_FILEINODES in RPM metadata represents a 64bit ino_t
as a uint32_t
RPMTAG_FILEDEVICES similarly represents a 64bit dev_t as uint16_t.
The truncation can cause aliasing issues. There is also information
leakage from the build system regarding inodes/devices.
Instead of truncating, the full value needs to be hashed to 32 bits,
and (for a dev_t) then truncated to 16bits.
