-
-commit af2b6f5ee6b171078b18246dd73f71cf6e350859 upstream.
-
-Resize the buffer used for paths into /proc/ to grant enough space
-for long PIDs. While at it, replace sprintf with snprintf to avoid
-buffer overflows if we ever ran out of space again.

-Fixes: #847

+Subject: [PATCH] lapi: Create if_addr.h and reuse it in rtnetlink.h
+
+There will be fix in next commit for missing IFA_F_NOPREFIXROUTE which
+requires creating lapi/if_addr.h. Thus move IFA_FLAGS to lapi/if_addr.h,
+as it belongs there and reuse lapi/if_addr.h in lapi/rtnetlink.h just
+like <linux/rtnetlink.h> includes <linux/if_addr.h>.

+Subject: [PATCH] lapi/if_addr.h: Define IFA_F_NOPREFIXROUTE
+
+and use it in icmp_rate_limit01.c.
+
+This fixes error on toolchains with very old kernel headers, e.g.
+Buildroot sourcery-arm:
+
+icmp_rate_limit01.c:82:3: error: 'IFA_F_NOPREFIXROUTE' undeclared (first use in this function)
+   IFA_F_NOPREFIXROUTE);
+
+Fixed because IFA_F_NOPREFIXROUTE was added in 3.14 and the oldest
+system we still support is Cent0S 7 with 3.10 kernel.
+
+NOTE: Cent0S 7 is obviously heavily patched thus it contains
+IFA_F_NOPREFIXROUTE and therefore CI build didn't catch this error.
