Pull networking fixes from David Miller: 1) The per-network-namespace loopback device, and thus its namespace, can have its teardown deferred for a long time if a kernel created TCP socket closes and the namespace is exiting meanwhile. The kernel keeps trying to finish the close sequence until it times out (which takes quite some time). Fix this by forcing the socket closed in this situation, from Dan Streetman. 2) Fix regression where we're trying to invoke the update_pmtu method on route types (in this case metadata tunnel routes) that don't implement the dst_ops method. Fix from Nicolas Dichtel. 3) Fix long standing memory corruption issues in r8169 driver by performing the chip statistics DMA programming more correctly. From Francois Romieu. 4) Handle local broadcast sends over VRF routes properly, from David Ahern. 5) Don't refire the DCCP CCID2 timer endlessly, otherwise the socket can never be released.

select(2) with wfds but no rfds must return when the socket is shut down by the peer. This way userspace notices socket activity and gets -EPIPE from the next write(2). Currently select(2) does not return for virtio-vsock when a SEND+RCV shutdown packet is received. This is because vsock_poll() only sets POLLOUT | POLLWRNORM for TCP_CLOSE, not the TCP_CLOSING state that the socket is in when the shutdown is received.

ccid2_hc_tx_rto_expire() timer callback always restarts the timer again and can run indefinitely (unless it is stopped outside), and after commit 120e9dab ("dccp: defer ccid_hc_tx_delete() at dismantle time"), which moved ccid_hc_tx_delete() (also includes sk_stop_timer()) from dccp_destroy_sock() to sk_destruct(), this started to happen quite often. The timer prevents releasing the socket, as a result, sk_destruct() won't be called.

For a while we've been having issues with seemingly random interrupts coming from nvidia cards when resuming them. Originally the fix for this was thought to be just re-arming the MSI interrupt registers right after re-allocating our IRQs, however it seems a lot of what we do is both wrong and not even nessecary. This was made apparent by what appeared to be a regression in the mainline kernel that started introducing suspend/resume issues for nouveau: a0c9259d (irq/matrix: Spread interrupts on allocation) After this commit was introduced, we started getting interrupts from the GPU before we actually re-allocated our own IRQ (see references below) and assigned the IRQ handler. Investigating this turned out that the problem was not with the commit, but the fact that nouveau even free/allocates it's irqs before and after suspend/resume. For starters: drivers in the linux kernel haven't had to handle freeing/re-allocating their IRQs during suspend/resume cycles for quite a while now. Nouveau seems to be one of the few drivers left that still does this, despite the fact there's no reason we actually need to since disabling interrupts from the device side should be enough, as the kernel is already smart enough to know to disable host-side interrupts for us before going into suspend. Since we were tearing down our IRQs by hand however, that means there was a short period during resume where interrupts could be received before we re-allocated our IRQ which would lead to us getting an unhandled IRQ. Since we never handle said IRQ and re-arm the interrupt registers, this would cause us to miss all of the interrupts from the GPU and cause our init process to start timing out on anything requiring interrupts. So, since this whole setup/teardown every suspend/resume cycle is useless anyway, move irq setup/teardown into the pci subdev's ctor/dtor functions instead so they're only called at driver load and driver unload. This should fix most of the issues with pending interrupts on resume, along with getting suspend/resume for nouveau to work again. As well, this probably means we can also just remove the msi rearm call inside nvkm_pci_init(). But since our main focus here is to fix suspend/resume before 4.15, we'll save that for a later patch.

When a tcp socket is closed, if it detects that its net namespace is exiting, close immediately and do not wait for FIN sequence. For normal sockets, a reference is taken to their net namespace, so it will never exit while the socket is open. However, kernel sockets do not take a reference to their net namespace, so it may begin exiting while the kernel socket is still open. In this case if the kernel socket is a tcp socket, it will stay open trying to complete its close sequence. The sock's dst(s) hold a reference to their interface, which are all transferred to the namespace's loopback interface when the real interfaces are taken down. When the namespace tries to take down its loopback interface, it hangs waiting for all references to the loopback interface to release, which results in messages like: unregister_netdevice: waiting for lo to become free. Usage count = 1 These messages continue until the socket finally times out and closes. Since the net namespace cleanup holds the net_mutex while calling its registered pernet callbacks, any new net namespace initialization is blocked until the current net namespace finishes exiting. After this change, the tcp socket notices the exiting net namespace, and closes immediately, releasing its dst(s) and their reference to the loopback interface, which lets the net namespace continue exiting.

In fixing the readdir+pagefault deadlock I accidentally introduced a stale entry regression in readdir. If we get close to full for the temporary buffer, and then skip a few delayed deletions, and then try to add another entry that won't fit, we will emit the entries we found and retry. Unfortunately we delete entries from our del_list as we find them, assuming we won't need them. However our pos will be with whatever our last entry was, which could be before the delayed deletions we skipped, so the next search will add the deleted entries back into our readdir buffer. So instead don't delete entries we find in our del_list so we can make sure we always find our delayed deletions. This is a slight perf hit for readdir with lots of pending deletions, but hopefully this isn't a common occurrence. If it is we can revist this and optimize it. cc: stable@vger.kernel.org Fixes: 23b5ec74 ("btrfs: fix readdir deadlock with pagefault") Signed-off-by: NJosef Bacik <jbacik@fb.com> Signed-off-by: NDavid Sterba <dsterba@suse.com>

Which means all ftrace stack tracing that happens from the function tracer would produce no results (that includes killing the max stack size tracer). I added a check to the ORC unwinder to see if the trampoline belonged to ftrace, and if it did, use the orc entry of the static trampoline that was used to create the dynamic one (it would be identical). Finally, I noticed that the skip values of the stack tracing were out of whack.

When finding an entry configured in HW that doesn't show in neigh_lookup() driver logs an error message.
