From ffe378c06c10b97806e2109a5d619a48a9c2940c Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Thu, 8 Oct 2026 16:31:56 +0300 Subject: [PATCH] ipv6: Report netns cookie in fib6_table_lookup tracepoint The first argument of the tracepoint is a pointer to the network namespace in which the FIB lookup was performed, but the tracepoint does not report information about it in the associated trace record, making it impossible to tell apart lookups performed in different namespaces. Report the network namespace cookie, as commit 27cb3de7f43a ("net: add net cookie for net device trace events") did for the net device tracepoints.
