Summary
Squashfs: reject negative file sizes in squashfs_read_inode()
Details

In the Linux kernel, the following vulnerability has been resolved:

Squashfs: reject negative file sizes in squashfsreadinode()

Syskaller reports a "WARNING in ovlcopyup_file" in overlayfs.

This warning is ultimately caused because the underlying Squashfs file system returns a file with a negative file size.

This commit checks for a negative file size and returns EINVAL.

[phillip@squashfs.org.uk: only need to check 64 bit quantity]
