Petr Machata says: ==================== selftests: forwarding: mirror_vlan: Fixlets This patchset includes two small fixes for the tests that were introduced in commit 1bb58d2d ("Merge branch 'Mirroring-tests-involving-VLAN'"). In patch #1, a "tc action trap" is uninstalled after the suite runs, instead of being installed again. In patch #2, a test in suite is renamed to differentiate it from another test of the same name. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

The test description is displayed with the PASS/FAIL resolution after the test is ran. There however already is one other test described exactly like this, which makes it unclear which of the tests passed or failed. Make the description unique.

Add regression tests for PF_PACKET transmission using packet_snd. The TPACKET ring interface has tests for transmission and reception. This is an initial stab at the same for the send call based interface. Packets are sent over loopback, then read twice. The entire packet is read from another packet socket and compared. The packet is also verified to arrive at a UDP socket for protocol conformance. The test sends a packet over loopback, testing the following options (not the full cross-product): - SOCK_DGRAM - SOCK_RAW - vlan tag - qdisc bypass - bind() and sendto() - virtio_net_hdr - csum offload (NOT actual csum feature, ignored on loopback) - gso Besides these basic functionality tests, the test runs from a set of bounds checks, positive and negative. Running over loopback, which has dev->min_header_len, it cannot generate variable length hhlen. Signed-off-by: NWillem de Bruijn <willemb@google.com> Signed-off-by: NDavid S.

If there is a significant amount of chains list search is too slow, so add an rhlist table for this. This speeds up ruleset loading: for every new rule we have to check if the name already exists in current generation. We need to be able to cope with duplicate chain names in case a transaction drops the nfnl mutex (for request_module) and the abort of this old transaction is still pending. The list is kept -- we need a way to iterate chains even if hash resize is in progress without missing an entry.

Before this patch, cloned expressions are released via ->destroy. This is a problem for the new connlimit expression since the ->destroy path drop a reference on the conntrack modules and it unregisters hooks. The new ->destroy_clone provides context that this expression is being released from the packet path, so it is mirroring ->clone(), where neither module reference is dropped nor hooks need to be unregistered - because this done from the control plane path from the ->init() path.

Use garbage collector to schedule removal of elements based of feedback from expression that this element comes with. Therefore, the garbage collector is not guided by timeout expirations in this new mode. The new connlimit expression sets on the NFT_EXPR_GC flag to enable this behaviour, the dynset expression needs to explicitly enable the garbage collector via set->ops->gc_init call.

Fix it, to match both the comment above it, and the original behaviour. Although anonymous pages are not marked PageDirty at first, we have an old habit of calling SetPageDirty when a page is removed from swap cache: so there's a category of ex-swap pages that are easily migratable, but were inadvertently excluded from compaction's async migration in 4.16.
