Tony Nguyen says: ==================== Intel Wired LAN Driver Updates 2021-02-01 This series contains updates to igc and i40e drivers. Kai-Heng Feng fixes igc to report unknown speed and duplex during suspend as an attempted read will cause errors. Kevin Lo sets the default value to -IGC_ERR_NVM instead of success for writing shadow RAM as this could miss a timeout. Also propagates the return value for Flow Control configuration to properly pass on errors for igc. Aleksandr reverts commit 2ad1274f ("i40e: don't report link up for a VF who hasn't enabled queues") as this can cause link flapping. * '1GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue: i40e: Revert "i40e: don't report link up for a VF who hasn't enabled queues" igc: check return value of ret_val in igc_config_fc_after_link_up igc: set the default return value to -IGC_ERR_NVM in igc_write_nvm_srwr igc: Report speed and duplex as unknown when device is runtime suspended ==================== Link: https://lore.kernel.org/r/20210201214618.852831-1-anthony.l.nguyen@intel.comSigned-off-by:

UDP/IP header of UDP GROed frag_skbs are not updated even after NAT forwarding. Only the header of head_skb from ip_finish_output_gso -> skb_gso_segment is updated but following frag_skbs are not updated. A call path skb_mac_gso_segment -> inet_gso_segment -> udp4_ufo_fragment -> __udp_gso_segment -> __udp_gso_segment_list does not try to update UDP/IP header of the segment list but copy only the MAC header. Update port, addr and check of each skb of the segment list in __udp_gso_segment_list. It covers both SNAT and DNAT. Fixes: 9fd1ff5d (udp: Support UDP fraglist GRO/GSO.) Signed-off-by:

There are multiple similar bugs implicitly introduced by the commit c0cfa2d8 ("vsock: add multi-transports support") and commit 6a2c0962 ("vsock: prevent transport modules unloading"). The bug pattern: [1] vsock_sock.transport pointer is copied to a local variable, [2] lock_sock() is called, [3] the local variable is used. VSOCK multi-transport support introduced the race condition: vsock_sock.transport value may change between [1] and [2]. Let's copy vsock_sock.transport pointer to local variables after the lock_sock() call. Fixes: c0cfa2d8 ("vsock: add multi-transports support") Signed-off-by:

Commit e5f0e8f8 ("net: sched: introduce and use qdisc tree flush/purge helpers") introduced qdisc tree flush/purge helpers, but erroneously used flush helper instead of purge helper in qdisc_replace function. This issue was found in our CI, that tests various qdisc setups by configuring qdisc and sending data through it. Call of invalid helper sporadically leads to corruption of vt_tree/cf_tree of hfsc_class that causes kernel oops: Oops: 0000 [#1] SMP PTI CPU: 1 PID: 0 Comm: swapper/1 Not tainted 5.11.0-8f6859df #1 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.10.2-0-g5f4c7b1-prebuilt.qemu-project.org 04/01/2014 RIP: 0010:rb_insert_color+0x18/0x190 Code: c3 31 c0 c3 0f 1f 40 00 66 2e 0f 1f 84 00 00 00 00 00 48 8b 07 48 85 c0 0f 84 05 01 00 00 48 8b 10 f6 c2 01 0f 85 34 01 00 00 <48> 8b 4a 08 49 89 d0 48 39 c1 74 7d 48 85 c9 74 32 f6 01 01 75 2d RSP: 0018:ffffc900000b8bb0 EFLAGS: 00010246 RAX: ffff8881ef4c38b0 RBX: ffff8881d956e400 RCX: ffff8881ef4c38b0 RDX: 0000000000000000 RSI: ffff8881d956f0a8 RDI: ffff8881d956e4b0 RBP: 0000000000000000 R08: 000000d5c4e249da R09: 1600000000000000 R10: ffffc900000b8be0 R11: ffffc900000b8b28 R12: 0000000000000001 R13: 000000000000005a R14: ffff8881f0905000 R15: ffff8881f0387d00 FS: 0000000000000000(0000) GS:ffff8881f8b00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000000000008 CR3: 00000001f4796004 CR4: 0000000000060ee0 Call Trace: <IRQ> init_vf.isra.19+0xec/0x250 [sch_hfsc] hfsc_enqueue+0x245/0x300 [sch_hfsc] ? fib_rules_lookup+0x12a/0x1d0 ? __dev_queue_xmit+0x4b6/0x930 ? hfsc_delete_class+0x250/0x250 [sch_hfsc] __dev_queue_xmit+0x4b6/0x930 ? ip6_finish_output2+0x24d/0x590 ip6_finish_output2+0x24d/0x590 ? ip6_output+0x6c/0x130 ip6_output+0x6c/0x130 ? __ip6_finish_output+0x110/0x110 mld_sendpack+0x224/0x230 mld_ifc_timer_expire+0x186/0x2c0 ? igmp6_group_dropped+0x200/0x200 call_timer_fn+0x2d/0x150 run_timer_softirq+0x20c/0x480 ? tick_sched_do_timer+0x60/0x60 ? tick_sched_timer+0x37/0x70 __do_softirq+0xf7/0x2cb irq_exit+0xa0/0xb0 smp_apic_timer_interrupt+0x74/0x150 apic_timer_interrupt+0xf/0x20 </IRQ> Fixes: e5f0e8f8 ("net: sched: introduce and use qdisc tree flush/purge helpers") Signed-off-by:

Returning -EBUSY in ibmvnic_remove() does not actually hold the removal procedure since driver core doesn't care for the return value (see __device_release_driver() in drivers/base/dd.c calling dev->bus->remove()) though vio_bus_remove (in arch/powerpc/platforms/pseries/vio.c) records the return value and passes it on. [1] During the device removal precedure, checking for resetting bit is dropped so that we can continue executing all the cleanup calls in the rest of the remove function. Otherwise, it can cause latent memory leaks and kernel crashes.

This reverts commit 2ad1274f VF queues were not brought up when PF was brought up after being downed if the VF driver disabled VFs queues during PF down. This could happen in some older or external VF driver implementations. The problem was that PF driver used vf->queues_enabled as a condition to decide what link-state it would send out which caused the issue. Remove the check for vf->queues_enabled in the VF link notify. Now VF will always be notified of the current link status. Also remove the queues_enabled member from i40e_vf structure as it is not used anymore. Otherwise VNF implementation was broken and caused a link flap. The original commit was a workaround to avoid breaking existing VFs though it's really a fault of the VF code not the PF. The commit should be safe to revert as all of the VFs we know of have been fixed. Also, since we now know there is a related bug in the workaround, removing it is preferred.

Following race condition was detected: <CPU A, t0> - neigh_flush_dev() is under execution and calls neigh_mark_dead(n) marking the neighbour entry 'n' as dead. <CPU B, t1> - Executing: __netif_receive_skb() -> __netif_receive_skb_core() -> arp_rcv() -> arp_process().arp_process() calls __neigh_lookup() which takes a reference on neighbour entry 'n'. <CPU A, t2> - Moves further along neigh_flush_dev() and calls neigh_cleanup_and_release(n), but since reference count increased in t2, 'n' couldn't be destroyed. <CPU B, t3> - Moves further along, arp_process() and calls neigh_update()-> __neigh_update() -> neigh_update_gc_list(), which adds the neighbour entry back in gc_list(neigh_mark_dead(), removed it earlier in t0 from gc_list) <CPU B, t4> - arp_process() finally calls neigh_release(n), destroying the neighbour entry. This leads to 'n' still being part of gc_list, but the actual neighbour structure has been freed. The situation can be prevented from happening if we disallow a dead entry to have any possibility of updating gc_list. This is what the patch intends to achieve.

AF_RXRPC sockets use UDP ports in encap mode. This causes socket and dst from an incoming packet to get stolen and attached to the UDP socket from whence it is leaked when that socket is closed. When a network namespace is removed, the wait for dst records to be cleaned up happens before the cleanup of the rxrpc and UDP socket, meaning that the wait never finishes. Fix this by moving the rxrpc (and, by dependence, the afs) private per-network namespace registrations to the device group rather than subsys group. This allows cached rxrpc local endpoints to be cleared and their UDP sockets closed before we try waiting for the dst records. The symptom is that lines looking like the following: unregister_netdevice: waiting for lo to become free get emitted at regular intervals after running something like the referenced syzbot test. Thanks to Vadim for tracking this down and work out the fix. Reported-by: syzbot+df400f2f24a1677cd7e0@syzkaller.appspotmail.com Reported-by:

It was reported that on RTL8125 network breaks under heavy UDP load, e.g. torrent traffic ([0], from comment 27). Realtek confirmed a hw bug and provided me with a test version of the r8125 driver including a workaround. Tests confirmed that the workaround fixes the issue. I modified the original version of the workaround to meet mainline code style.

The main arcnet interrupt handler calls arcnet_close() then arcnet_open(), if the RESET status flag is encountered. This is invalid: 1) In general, interrupt handlers should never call ->ndo_stop() and ->ndo_open() functions. They are usually full of blocking calls and other methods that are expected to be called only from drivers init and exit code paths. 2) arcnet_close() contains a del_timer_sync(). If the irq handler interrupts the to-be-deleted timer, del_timer_sync() will just loop forever. 3) arcnet_close() also calls tasklet_kill(), which has a warning if called from irq context. 4) For device reset, the sequence "arcnet_close(); arcnet_open();" is not complete. Some children arcnet drivers have special init/exit code sequences, which then embed a call to arcnet_open() and arcnet_close() accordingly. Check drivers/net/arcnet/com20020.c. Run the device RESET sequence from a scheduled workqueue instead. Signed-off-by:Ahmed S. Darwish <a.darwish@linutronix.de> Signed-off-by:

Ido Schimmel says: ==================== mlxsw: Various fixes Patch #1 fixes wrong invocation of mausezahn in a couple of selftests. The tests started failing after Fedora updated their libnet package from version 1.1.6 to 1.2.1. With the fix the tests pass regardless of libnet version.

The purpose of the delayed work in the SPAN module is to potentially update the destination port and various encapsulation parameters of SPAN agents that point to a VLAN device or a GRE tap. The destination port can change following the insertion of a new route, for example. SPAN agents that point to a physical port or the CPU port are static and never change throughout the lifetime of the SPAN agent. Therefore, skip over them in the delayed work. This fixes an issue where the delayed work overwrites the policer that was set on a SPAN agent pointing to the CPU. Modifying the delayed work to inherit the original policer configuration is error-prone, as the same will be needed for any new parameter.

Pull locking fixes from Thomas Gleixner: "A set of PI futex fixes: - Address a longstanding issue where the user space part of the PI futex is not writeable. The kernel returns with inconsistent state which can in the worst case result in a UAF of a tasks kernel stack. The solution is to establish consistent kernel state which makes future operations on the futex fail because user space and kernel space state are inconsistent. Not a problem as PI futexes fundamentaly require a functional RW mapping and if user space pulls the rug under it, then it can keep the pieces it asked for. - Address an issue where the return value is incorrect in case that the futex was acquired after a timeout/signal made the waiter drop out of the rtmutex wait. In one of the corner cases the kernel returned an error code despite having successfully acquired the futex" * tag 'locking-urgent-2021-01-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: futex: Handle faults correctly for PI futexes futex: Simplify fixup_pi_state_owner() futex: Use pi_state_update_owner() in put_pi_state() rtmutex: Remove unused argument from rt_mutex_proxy_unlock() futex: Provide and use pi_state_update_owner() futex: Replace pointless printk in fixup_owner() futex: Ensure the correct return value from futex_lock_pi() -

This reverts commit dde3c6b7. syzbot report a double-free bug. The following case can cause this bug. - mm/slab_common.c: create_cache(): if the __kmem_cache_create() fails, it does: out_free_cache: kmem_cache_free(kmem_cache, s); - but __kmem_cache_create() - at least for slub() - will have done sysfs_slab_add(s) -> sysfs_create_group() .. fails .. -> kobject_del(&s->kobj); .. which frees s ... We can't remove the kmem_cache_free() in create_cache(), because other error cases of __kmem_cache_create() do not free this. So, revert the commit dde3c6b7 ("mm/slub: fix a memory leak in sysfs_slab_add()") to fix this.
