Instead, use inet_ntoa_r() with a buffer on the caller's stack. This code had an INET6 conditional before this commit, but opt_inet6.h was not included, so INET6 was never defined. Apparently, pf's OS fingerprinting hasn't worked with IPv6 for quite some time. This commit might fix it, but I didn't test that. Relnotes: yes (if I/someone can test pf OS fingerprinting with IPv6) Sponsored by: Dell EMC |
