When VF NIC client's init_instance() succeeds, it means this client has been registered successfully, so we use HCLGEVF_STATE_NIC_REGISTERED to indicate that. And before calling VF NIC client's uninit_instance(), we clear this state. So any operation of VF NIC client from HCLGEVF is not allowed if this state is not set. Signed-off-by:

Eric Dumazet says: ==================== inet: frags: followup to 'inet-frags-avoid-possible-races-at-netns-dismantle' Latest patch series ('inet-frags-avoid-possible-races-at-netns-dismantle') brought another syzbot report shown in the third patch changelog. While fixing the issue, I had to call inet_frags_fini() later in IPv6 and ilowpan. Also I believe a completion is needed to ensure proper dismantle at module removal. ==================== Signed-off-by: -

As caught by syzbot [1], the rcu grace period that is respected before fqdir_rwork_fn() proceeds and frees fqdir is not enough to prevent inet_frag_destroy_rcu() being run after the freeing. We need a proper rcu_barrier() synchronization to replace the one we had in inet_frags_fini() We also have to fix a potential problem at module removal : inet_frags_fini() needs to make sure that all queued work queues (fqdir_rwork_fn) have completed, otherwise we might call kmem_cache_destroy() too soon and get another use-after-free.

Both IPv6 and 6lowpan are calling inet_frags_fini() too soon. inet_frags_fini() is dismantling a kmem_cache, that might be needed later when unregister_pernet_subsys() eventually has to remove frags queues from hash tables and free them. This fixes potential use-after-free, and is a prereq for the following patch. Fixes: d4ad4d22 ("inet: frags: use kmem_cache for inet_frag_queue") Signed-off-by:

I was really surprised that the IPv6 mtu exception followed by redirect test was passing as nothing about the code suggests it should. The problem is actually with the logic in the test script. Fix the test cases as follows: 1. add debug function to dump the initial and redirect gateway addresses for ipv6. This is shown only in verbose mode. It helps verify the output of 'route get'. 2. fix the check_exception logic for the reset case to make sure that for IPv4 neither mtu nor redirect appears in the 'route get' output. For IPv6, make sure mtu is not present and the gateway is the initial R1 lladdr. 3. fix the reset logic by using a function to delete the routes added by initial_route_*. This format works better for the nexthop version of the tests. While improving the test cases, go ahead and ensure that forwarding is disabled since IPv6 redirect requires it. Also, runs with kernel debugging enabled sometimes show a failure with one of the ipv4 tests, so spread the pings over longer time interval. The end result is that 2 tests now show failures: TEST: IPv6: mtu exception plus redirect [FAIL] and the VRF version. This is a bug in the IPv6 logic that will need to be fixed separately. Redirect followed by MTU works because __ip6_rt_update_pmtu hits the 'if (!rt6_cache_allowed_for_pmtu(rt6))' path and updates the mtu on the exception rt6_info. MTU followed by redirect does not have this logic. rt6_do_redirect creates a new exception and then rt6_insert_exception removes the old one which has the MTU exception.

PHY drivers don't have to and shouldn't fiddle with phylib internals. Most of the code in bcm87xx_config_init() can be removed because phylib takes care. In addition I replaced usage of PHY_10GBIT_FEC_FEATURES with an implementation of the get_features callback. PHY_10GBIT_FEC_FEATURES is used by this driver only and it's questionable whether there will be any other PHY supporting this mode only. Having said that in one of the next kernel versions we may decide to remove it. Signed-off-by:

Eric Dumazet says: ==================== inet: frags: avoid possible races at netns dismantle This patch series fixes a race happening on netns dismantle with frag queues. While rhashtable_free_and_destroy() is running, concurrent timers might run inet_frag_kill() and attempt rhashtable_remove_fast() calls. This is not allowed by rhashtable logic. Since I do not want to add expensive synchronize_rcu() calls in the netns dismantle path, I had to no longer inline netns_frags structures, but dynamically allocate them. The ten first patches make this preparation, so that the last patch clearly shows the fix. As this patch series is not exactly trivial, I chose to target 5.3. We will backport it once soaked a bit. ==================== Signed-off-by: -

syszbot found an interesting use-after-free [1] happening while IPv4 fragment rhashtable was destroyed at netns dismantle. While no insertions can possibly happen at the time a dismantling netns is destroying this rhashtable, timers can still fire and attempt to remove elements from this rhashtable. This is forbidden, since rhashtable_free_and_destroy() has no synchronization against concurrent inserts and deletes. Add a new fqdir->dead flag so that timers do not attempt a rhashtable_remove_fast() operation. We also have to respect an RCU grace period before starting the rhashtable_free_and_destroy() from process context, thus we use rcu_work infrastructure. This is a refinement of a prior rough attempt to fix this bug : https://marc.info/?l=linux-netdev&m=153845936820900&w=2 Since the rhashtable cleanup is now deferred to a work queue, netns dismantles should be slightly faster.

Following patch will add rcu grace period before fqdir rhashtable destruction, so we need to dynamically allocate fqdir structures to not force expensive synchronize_rcu() calls in netns dismantle path. Signed-off-by:

fqdir will soon be dynamically allocated. We need to reach the struct net pointer from fqdir, so add it, and replace the various container_of() constructs by direct access to the new field. Signed-off-by:
