This patchset introduces a new eBPF hash map whose elements have
timeouts. Patch 1 is the implementation of timeout map, patch 2 adds
some test cases for timeout map in test_maps, and patch 3 adds a test
case in map ptr test.
Please check each patch description for more details.

RT_TOS() only masks one of the two ECN bits. Therefore rpfilter_mt()
treats Not-ECT or ECT(1) packets in a different way than those with
ECT(0) or CE.
Reproducer:
Create two netns, connected with a veth:
$ ip netns add ns0
$ ip netns add ns1
$ ip link add name veth01 netns ns0 type veth p
Functions that end up calling fib_table_lookup() should clear the ECN
bits from the TOS, otherwise ECT(0) and ECT(1) packets can be treated
differently.
Most functions already clear the ECN bits, but there are a few cases
where this is not done. This series only fixes the ones related to
source ad
udp_v4_early_demux() is the only function that calls
ip_mc_validate_source() with a TOS that hasn't been masked with
IPTOS_RT_MASK.
This results in different behaviours for incoming multicast UDPv4
packets, depending on if ip_mc_validate_source() is called from the
early-demux path (udp_v4_early_d
