2019-08-01mvpp2: fix panic on module removalMatteo Croce1-3/+2
mvpp2 uses a delayed workqueue to gather traffic statistics. On module removal the workqueue can be destroyed before calling cancel_delayed_work_sync() on its works. Fix it by moving the destroy_workqueue() call after mvpp2_port_remove(). Also remove an unneeded call to flush_workqueue() # rmmod mvpp2 [ 2743.311722] mvpp2 f4000000.ethernet eth1: phy link down 10gbase-kr/10Gbps/Full [ 2743.320063] mvpp2 f4000000.ethernet eth1: Link is Down [ 2743.572263] mvpp2 f4000000.ethernet eth2: phy link down sgmii/1Gbps/Full [ 2743.580076] mvpp2 f4000000.ethernet eth2: Link is Down [ 2744.102169] mvpp2 f2000000.ethernet eth0: phy link down 10gbase-kr/10Gbps/Full [ 2744.110441] mvpp2 f2000000.ethernet eth0: Link is Down [ 2744.115614] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000 [ 2744.115615] Mem abort info: [ 2744.115616] ESR = 0x96000005 [ 2744.115617] Exception class = DABT (current EL), IL = 32 bits [ 2744.115618] SET = 0, FnV = 0 [ 2744.115619] EA = 0, S1PTW = 0 [ 2744.115620] Data abort info: [ 2744.115621] ISV = 0, ISS = 0x00000005 [ 2744.115622] CM = 0, WnR = 0 [ 2744.115624] user pgtable: 4k pages, 39-bit VAs, pgdp=0000000422681000 [ 2744.115626] [0000000000000000] pgd=0000000000000000, pud=0000000000000000 [ 2744.115630] Internal error: Oops: 96000005 [#1] SMP [ 2744.115632] Modules linked in: mvpp2(-) algif_hash af_alg nls_iso8859_1 nls_cp437 vfat fat xhci_plat_hcd m25p80 spi_nor xhci_hcd mtd usbcore i2c_mv64xxx sfp usb_common marvell10g phy_generic spi_orion mdio_i2c i2c_core mvmdio phylink sbsa_gwdt ip_tables x_tables autofs4 [last unloaded: mvpp2] [ 2744.115654] CPU: 3 PID: 8357 Comm: kworker/3:2 Not tainted 5.3.0-rc2 #1 [ 2744.115655] Hardware name: Marvell 8040 MACCHIATOBin Double-shot (DT) [ 2744.115665] Workqueue: events_power_efficient phylink_resolve [phylink] [ 2744.115669] pstate: a0000085 (NzCv daIf -PAN -UAO) [ 2744.115675] pc : __queue_work+0x9c/0x4d8 [ 2744.115677] lr : __queue_work+0x170/0x4d8 [ 2744.115678] sp : ffffff801001bd50 [ 2744.115680] x29: ffffff801001bd50 x28: ffffffc422597600 [ 2744.115684] x27: ffffff80109ae6f0 x26: ffffff80108e4018 [ 2744.115688] x25: 0000000000000003 x24: 0000000000000004 [ 2744.115691] x23: ffffff80109ae6e0 x22: 0000000000000017 [ 2744.115694] x21: ffffffc42c030000 x20: ffffffc42209e8f8 [ 2744.115697] x19: 0000000000000000 x18: 0000000000000000 [ 2744.115699] x17: 0000000000000000 x16: 0000000000000000 [ 2744.115701] x15: 0000000000000010 x14: ffffffffffffffff [ 2744.115702] x13: ffffff8090e2b95f x12: ffffff8010e2b967 [ 2744.115704] x11: ffffff8010906000 x10: 0000000000000040 [ 2744.115706] x9 : ffffff80109223b8 x8 : ffffff80109223b0 [ 2744.115707] x7 : ffffffc42bc00068 x6 : 0000000000000000 [ 2744.115709] x5 : ffffffc42bc00000 x4 : 0000000000000000 [ 2744.115710] x3 : 0000000000000000 x2 : 0000000000000000 [ 2744.115712] x1 : 0000000000000008 x0 : ffffffc42c030000 [ 2744.115714] Call trace: [ 2744.115716] __queue_work+0x9c/0x4d8 [ 2744.115718] delayed_work_timer_fn+0x28/0x38 [ 2744.115722] call_timer_fn+0x3c/0x180 [ 2744.115723] expire_timers+0x60/0x168 [ 2744.115724] run_timer_softirq+0xbc/0x1e8 [ 2744.115727] __do_softirq+0x128/0x320 [ 2744.115731] irq_exit+0xa4/0xc0 [ 2744.115734] __handle_domain_irq+0x70/0xc0 [ 2744.115735] gic_handle_irq+0x58/0xa8 [ 2744.115737] el1_irq+0xb8/0x140 [ 2744.115738] console_unlock+0x3a0/0x568 [ 2744.115740] vprintk_emit+0x200/0x2a0 [ 2744.115744] dev_vprintk_emit+0x1c8/0x1e4 [ 2744.115747] dev_printk_emit+0x6c/0x7c [ 2744.115751] __netdev_printk+0x104/0x1d8 [ 2744.115752] netdev_printk+0x60/0x70 [ 2744.115756] phylink_resolve+0x38c/0x3c8 [phylink] [ 2744.115758] process_one_work+0x1f8/0x448 [ 2744.115760] worker_thread+0x54/0x500 [ 2744.115762] kthread+0x12c/0x130 [ 2744.115764] ret_from_fork+0x10/0x1c [ 2744.115768] Code: aa1403e0 97fffbbe aa0003f5 b4000700 (f9400261) Fixes: 118d6298f6f0 ("net: mvpp2: add ethtool GOP statistics") Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Matteo Croce <mcroce@redhat.com> Acked-by: Antoine Tenart <antoine.tenart@bootlin.com> Signed-off-by: David S.

2019-07-31net: bridge: mcast: don't delete permanent entries when fast leave is enabledNikolay Aleksandrov1-0/+3
When permanent entries were introduced by the commit below, they were exempt from timing out and thus igmp leave wouldn't affect them unless fast leave was enabled on the port which was added before permanent entries existed. It shouldn't matter if fast leave is enabled or not if the user added a permanent entry it shouldn't be deleted on igmp leave.

2019-07-31net: phy: phy_led_triggers: Fix a possible null-pointer dereference in phy_led_trigger_change_speed()Jia-Ju Bai1-1/+2
In phy_led_trigger_change_speed(), there is an if statement on line 48 to check whether phy->last_triggered is NULL: if (!phy->last_triggered) When phy->last_triggered is NULL, it is used on line 52: led_trigger_event(&phy->last_triggered->trigger, LED_OFF); Thus, a possible null-pointer dereference may occur. To fix this bug, led_trigger_event(&phy->last_triggered->trigger, LED_OFF) is called when phy->last_triggered is not NULL.

2019-07-31isdn: hfcsusb: Fix mISDN driver crash caused by transfer buffer on the stackJuliana Rodrigueiro1-1/+11
Since linux 4.9 it is not possible to use buffers on the stack for DMA transfers. During usb probe the driver crashes with "transfer buffer is on stack" message. This fix k-allocates a buffer to be used on "read_reg_atomic", which is a macro that calls "usb_control_msg" under the hood.

2019-07-30compat_ioctl: pppoe: fix PPPOEIOCSFWD handlingArnd Bergmann6-3/+25
Support for handling the PPPOEIOCSFWD ioctl in compat mode was added in linux-2.5.69 along with hundreds of other commands, but was always broken sincen only the structure is compatible, but the command number is not, due to the size being sizeof(size_t), or at first sizeof(sizeof((struct sockaddr_pppox)), which is different on 64-bit architectures. Guillaume Nault adds: And the implementation was broken until 2016 (see 29e73269aa4d ("pppoe: fix reference counting in PPPoE proxy")), and nobody ever noticed. I should probably have removed this ioctl entirely instead of fixing it. Clearly, it has never been used. Fix it by adding a compat_ioctl handler for all pppoe variants that translates the command number and then calls the regular ioctl function. All other ioctl commands handled by pppoe are compatible between 32-bit and 64-bit, and require compat_ptr() conversion. This should apply to all stable kernels.

2019-07-30net: stmmac: Sync RX Buffer upon allocationJose Abreu1-3/+10
With recent changes that introduced support for Page Pool in stmmac, Jon reported that NFS boot was no longer working on an ARM64 based platform that had the IP behind an IOMMU. As Page Pool API does not guarantee DMA syncing because of the use of DMA_ATTR_SKIP_CPU_SYNC flag, we have to explicit sync the whole buffer upon re-allocation because we are always re-using same pages. In fact, ARM64 code invalidates the DMA area upon two situations [1]: - sync_single_for_cpu(): Invalidates if direction != DMA_TO_DEVICE - sync_single_for_device(): Invalidates if direction == DMA_FROM_DEVICE So, as we must invalidate both the current RX buffer and the newly allocated buffer we propose this fix.

Don't take the risk to change completely the entry condition to iwl_mvm_release_frames, but don't update the head_sn is the NSSN is more than 2048 packets ahead of us. Since this just cannot be right. This means that the scenario described here happened. We are queue 0.

2019-07-30iwlwifi: mvm: add a loose synchronization of the NSSN across Rx queuesEmmanuel Grumbach3-15/+56
In order to support MSI-X efficiently, we want to avoid communication across Rx queues. Each Rx queue should have all the data it needs to process a packet. The reordering buffer is a challenge in the MSI-X world since we can have a single BA session whose packets are directed to different queues. This is why each queue has its own reordering buffer. The hardware is able to hint the driver whether we have a hole or not, which allows the driver to know whether it can release a packet or not. This indication is called NSSN. Roughly, if the packet's SN is lower than the NSSN, we can release the packet to the stack. The NSSN is the SN of the newest packet received without any holes + 1. This is working as long as we don't have packets that we release because of a timeout. When that happens, we could have taken the decision to release a packet after we have been waiting for its predecessor for too long. If this predecessor comes later, we have to drop it because we can't release packets out of order. In that case, the hardware will give us an indication that we can we release the packet (SN < NSSN), but the packet still needs to be dropped. This is why we sometimes need to ignore the NSSN and we track the head_sn in software. Here is a specific example of this: 1) Rx queue 1 got packets: 480, 482, 483 2) We release 480 to to the stack and wait for 481 3) NSSN is now 481 4) The timeout expires 5) We release 482 and 483, NSSN is still 480 6) 481 arrives its NSSN is 484. We need to drop 481 even if 481 < 484. This is why we'll update the head_sn to 484 at step 2. The flow now is: 1) Rx queue 1 got packets: 480, 482, 483 2) We release 480 to to the stack and wait for 481 3) NSSN is now 481 / head_sn is 481 4) The timeout expires 5) We release 482 and 483, NSSN is still 480 but head_sn is 484. 6) 481 arrives its NSSN is 484, but head_sn is 484 and we drop it. This code introduces another problem in case all the traffic goes well (no hole, no timeout): Rx queue 1: 0 -> 483 (head_sn = 484) Rx queue 2: 501 -> 4095 (head_sn = 0) Rx queue 2: 0 -> 480 (head_sn = 481) Rx queue 1: 481 but head_sn = 484 and we drop it. At this point, the SN of queue 1 is far behind: more than 4040 packets behind. Queue 1 will consider 481 "old" because 481 is in [501-64:501] whereas it is a very new packet. In order to fix that, send an Rx notification from time to time (twice across the full set of 4096 packets) to make sure no Rx queue is lagging too far behind. What will happen then is: Rx queue 1: 0 -> 483 (head_sn = 484) Rx queue 2: 501 -> 2047 (head_sn = 2048) Rx queue 1: Sync nofication (head_sn = 2048) Rx queue 2: 2048 -> 4095 (head_sn = 0) Rx queue 1: Sync notification (head_sn = 0) Rx queue 2: 1 -> 481 (head_sn = 482) Rx queue 1: 481 and head_sn = 0. In queue 1's data, head_sn is now 0, the packet coming in is 481, it'll understand that the new packet is new and it won't be dropped.

2019-07-30iwlwifi: mvm: don't send GEO_TX_POWER_LIMIT on version < 41Luca Coelho1-7/+15
Firmware versions before 41 don't support the GEO_TX_POWER_LIMIT command, and sending it to the firmware will cause a firmware crash. We allow this via debugfs, so we need to return an error value in case it's not supported. This had already been fixed during init, when we send the command if the ACPI WGDS table is present. Fix it also for the other, userspace-triggered case.

2019-07-30iwlwifi: mvm: avoid races in rate init and rate performMordechay Goodstein4-5/+51
Rate perform uses the lq_sta table to calculate the next rate to scale while rate init resets the same table, Rate perform is done in soft irq context in parallel to rate init that can be called in case we are doing changes like AP changes BW or moving state for auth to assoc.

2019-07-30iwlwifi: mvm: disable TX-AMSDU on older NICsJohannes Berg1-1/+13
On older NICs, we occasionally see issues with A-MSDU support, where the commands in the FIFO get confused and then we see an assert EDC because the next command in the FIFO isn't TX. We've tried to isolate this issue and understand where it comes from, but haven't found any errors in building the A-MSDU in software. At least for now, disable A-MSDU support on older hardware so that users can use it again without fearing the assert. This fixes https://bugzilla.kernel.org/show_bug.cgi?id=203315.

2019-07-30mwifiex: fix 802.11n/WPA detectionBrian Norris2-1/+3
Commit 63d7ef36103d ("mwifiex: Don't abort on small, spec-compliant vendor IEs") adjusted the ieee_types_vendor_header struct, which inadvertently messed up the offsets used in mwifiex_is_wpa_oui_present(). Add that offset back in, mirroring mwifiex_is_rsn_oui_present(). As it stands, commit 63d7ef36103d breaks compatibility with WPA (not WPA2) 802.11n networks, since we hit the "info: Disable 11n if AES is not supported by AP" case in mwifiex_is_network_compatible().

2019-07-30rxrpc: Fix the lack of notification when sendmsg() fails on a DATA packetDavid Howells1-0/+1
Fix the fact that a notification isn't sent to the recvmsg side to indicate a call failed when sendmsg() fails to transmit a DATA packet with the error ENETUNREACH, EHOSTUNREACH or ECONNREFUSED. Without this notification, the afs client just sits there waiting for the call to complete in some manner (which it's not now going to do), which also pins the rxrpc call in place. This can be seen if the client has a scope-level IPv6 address, but not a global-level IPv6 address, and we try and transmit an operation to a server's IPv6 address. Looking in /proc/net/rxrpc/calls shows completed calls just sat there with an abort code of RX_USER_ABORT and an error code of -ENETUNREACH.

2019-07-30rxrpc: Fix potential deadlockDavid Howells3-1/+20
There is a potential deadlock in rxrpc_peer_keepalive_dispatch() whereby rxrpc_put_peer() is called with the peer_hash_lock held, but if it reduces the peer's refcount to 0, rxrpc_put_peer() calls __rxrpc_put_peer() - which the tries to take the already held lock. Fix this by providing a version of rxrpc_put_peer() that can be called in situations where the lock is already held. The bug may produce the following lockdep report: ============================================ WARNING: possible recursive locking detected 5.2.0-next-20190718 #41 Not tainted -------------------------------------------- kworker/0:3/21678 is trying to acquire lock: 00000000aa5eecdf (&(&rxnet->peer_hash_lock)->rlock){+.-.}, at: spin_lock_bh /./include/linux/spinlock.h:343 [inline] 00000000aa5eecdf (&(&rxnet->peer_hash_lock)->rlock){+.-.}, at: __rxrpc_put_peer /net/rxrpc/peer_object.c:415 [inline] 00000000aa5eecdf (&(&rxnet->peer_hash_lock)->rlock){+.-.}, at: rxrpc_put_peer+0x2d3/0x6a0 /net/rxrpc/peer_object.c:435 but task is already holding lock: 00000000aa5eecdf (&(&rxnet->peer_hash_lock)->rlock){+.-.}, at: spin_lock_bh /./include/linux/spinlock.h:343 [inline] 00000000aa5eecdf (&(&rxnet->peer_hash_lock)->rlock){+.-.}, at: rxrpc_peer_keepalive_dispatch /net/rxrpc/peer_event.c:378 [inline] 00000000aa5eecdf (&(&rxnet->peer_hash_lock)->rlock){+.-.}, at: rxrpc_peer_keepalive_worker+0x6b3/0xd02 /net/rxrpc/peer_event.c:430 Fixes: 330bdcfadcee ("rxrpc: Fix the keepalive generator [ver #2]") Reported-by: syzbot+72af434e4b3417318f84@syzkaller.appspotmail.com Signed-off-by: David Howells <dhowells@redhat.com> Reviewed-by: Marc Dionne <marc.dionne@auristor.com> Reviewed-by: Jeffrey Altman <jaltman@auristor.com>
