Hi all, After merging the netfilter-next tree, today's linux-next build (x86_64 allmodconfig) produced this warning: In file included from net/netfilter/ipvs/ip_vs_core.c:52: net/netfilter/ipvs/ip_vs_core.c: In function 'ip_vs_in_icmp': include/net/ip_vs.h:233:4: warning: 'outer_proto' may be used uninitialized in this function [-Wmaybe-uninitialized] 233 | printk(KERN_DEBUG pr_fmt(msg), ##__VA_ARGS__); \ | ^~~~~~ net/netfilter/ipvs/ip_vs_core.c:1666:8: note: 'outer_proto' was declared here 1666 | char *outer_proto; | ^~~~~~~~~~~ Introduced by commit 73348fed35d0 ("ipvs: optimize tunnel dumps for icmp errors") -- Cheers, Stephen Rothwell
