-Subject: ip6_gre: fix ip6gre_err() invalid reads
-
-Andrey Konovalov reported out of bound accesses in ip6gre_err()
-
-If GRE flags contains GRE_KEY, the following expression
-*(((__be32 *)p) + (grehlen / 4) - 1)
-
-accesses data ~40 bytes after the expected point, since
-grehlen includes the size of IPv6 headers.
-
-Let's use a "struct gre_base_hdr *greh" pointer to make this
-code more readable.
-
-p[1] becomes greh->protocol.
-grhlen is the GRE header length.
-
-Fixes: c12b395a4664 ("gre: Support GRE over IPv6")
