[PATCH 4.9 19/30] bpf: Fix buggy rsh min/max bounds tracking

[Greg Kroah-Hartman]

From: Daniel Borkmann <daniel@iogearbox.net>

[ no upstream commit ]

Fix incorrect bounds tracking for RSH opcode. Commit f23cc643f9ba ("bpf: fix
range arithmetic for bpf map access") had a wrong assumption about min/max
bounds. The new dst_reg->min_value needs to be derived by right shifting the
max_val bounds, not min_val, and likewise new dst_reg->max_value needs to be
derived by right shifting the min_val bounds, not max_val. Later stable kernels
than 4.9 are not affected since bounds tracking was overall reworked and they
already track this similarly as in the fix.
