After the commit2b760fcf5c("ipv6: hook up exception table to store dst cache"), the fib6 gc is not started after the creation of a RTF_CACHE via a redirect or pmtu update, since fib6_add() isn't invoked anymore for such dsts. We need the fib6 gc to run periodically to clean the RTF_CACHE, or the dst will stay there forever. Fix it by explicitly calling fib6_force_start_gc() on successful exception creation. gc_args->more accounting will ensure that the gc timer will run for whatever time needed to properly clean the table. v2 -> v3: - clarified the commit message Fixes:2b760fcf5c("ipv6: hook up exception table to store dst cache") Signed-off-by: Paolo Abeni <pabeni@redhat.com> Acked-by: Wei Wang <weiwan@google.com> Acked-by: Martin KaFai Lau <kafai@fb.com> Signed-off-by: David S.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
