+Subject: [PATCH] setup.py: do not report missing dependencies for disabled
+ modules
+
+Reporting those missing dependencies is misleading as the modules would not
+have been built anyway. This particularly matters in oe-core's automated
+build completeness checker which relies on the report.

+Subject: [PATCH] [3.7] bpo-41004: Resolve hash collisions for IPv4Interface
+ and IPv6Interface (GH-21033) (GH-21231)
+
+CVE-2020-14422
+The __hash__() methods of classes IPv4Interface and IPv6Interface had issue
+of generating constant hash values of 32 and 128 respectively causing hash collisions.
+The fix uses the hash() function to generate hash values for the objects
+instead of XOR operation
+(cherry picked from commit b30ee26e366bf509b7538d79bfec6c6d38d53f28)

++CVE-2020-14422: The __hash__() methods of  ipaddress.IPv4Interface and ipaddress.IPv6Interface incorrectly generated constant hash values of 32 and 128 respectively. This resulted in always causing hash collisions. The fix uses hash() to generate hash values for the tuple of (address, mask length, network address).
