If anyone has any objections, please let me know. ------------------ From: Arnd Bergmann [ Upstream commit 83ed7d1fe2d2d4a11b30660dec20168bb473d9c1 ] My randconfig builds came across an old missing dependency for ILA: ERROR: "dst_cache_set_ip6" [net/ipv6/ila/ila.ko] undefined! ERROR: "dst_cache_get" [net/ipv6/ila/ila.ko] undefined! ERROR: "dst_cache_init" [net/ipv6/ila/ila.ko] undefined! ERROR: "dst_cache_destroy" [net/ipv6/ila/ila.ko] undefined! We almost never run into this by accident because randconfig builds end up selecting DST_CACHE from some other tunnel protocol, and this one appears to be the only one missing the explicit 'select'. >>>From all I can tell, this problem first appeared in linux-4.9 when dst_cache support got added to ILA.
