[ Upstream commit c6384560 ] CONFIG_CAN_LEDS is deprecated. When trying to use the generic netdev trigger as suggested, there's a small inconsistency with the link property: The LED is on initially, stays on when the device is brought up, and then turns off (as expected) when the device is brought down. Make sure the LED always reflects the state of the CAN device. Signed-off-by:

[ Upstream commit 1be79d89 ] The TC filters used in the test do not work with veth devices because the outer Ethertype is 802.1Q and not IPv4. The test passes with mlxsw netdevs since the hardware always looks at "The first Ethertype that does not point to either: VLAN, CNTAG or configurable Ethertype". Fix this by matching on the VLAN ID instead, but on the ingress side. The reason why this is not performed at egress is explained in the commit cited below.

[ Upstream commit 12185dfe ] The following scenario was encountered during testing of logical partition mobility on pseries partitions with bonded ibmvnic adapters in LACP mode. 1. Driver receives a signal that the device has been swapped, and it needs to reset to initialize the new device. 2. Driver reports loss of carrier and begins initialization. 3. Bonding driver receives NETDEV_CHANGE notifier and checks the slave's current speed and duplex settings. Because these are unknown at the time, the bond sets its link state to BOND_LINK_FAIL and handles the speed update, clearing AD_PORT_LACP_ENABLE. 4. Driver finishes recovery and reports that the carrier is on. 5. Bond receives a new notification and checks the speed again. The speeds are valid but miimon has not altered the link state yet. AD_PORT_LACP_ENABLE remains off. Because the slave's link state is still BOND_LINK_FAIL, no further port checks are made when it recovers. Though the slave devices are operational and have valid speed and duplex settings, the bond will not send LACPDU's. The simplest fix I can see is to force another speed check in bond_miimon_commit. This way the bond will update AD_PORT_LACP_ENABLE if needed when transitioning from BOND_LINK_FAIL to BOND_LINK_UP.

[ Upstream commit c8eee413 ] "sendmsg6: rewrite IP & port (C)" fails on s390, because the code in sendmsg_v6_prog() assumes that (ctx->user_ip6[0] & 0xFFFF) refers to leading IPv6 address digits, which is not the case on big-endian machines. Since checking bitwise operations doesn't seem to be the point of the test, replace two short comparisons with a single int comparison. Signed-off-by:

[ Upstream commit 8dd26dff ] DPCM uses snd_soc_dapm_dai_get_connected_widgets to build a list of the widgets connected to a specific front end DAI so it can search through this list for available back end DAIs. The custom_stop_condition was added to is_connected_ep to facilitate this list not containing more widgets than is necessary. Doing so both speeds up the DPCM handling as less widgets need to be searched and avoids issues with CODEC to CODEC links as these would be confused with back end DAIs if they appeared in the list of available widgets. custom_stop_condition was implemented by aborting the graph walk when the condition is triggered, however there is an issue with this approach. Whilst walking the graph is_connected_ep should update the endpoints cache on each widget, if the walk is aborted the number of attached end points is unknown for that sub-graph. When the stop condition triggered, the original patch ignored the triggering widget and returned zero connected end points; a later patch updated this to set the triggering widget's cache to 1 and return that. Both of these approaches result in inaccurate values being stored in various end point caches as the values propagate back through the graph, which can result in later issues with widgets powering/not powering unexpectedly. As the original goal was to reduce the size of the widget list passed to the DPCM code, the simplest solution is to limit the functionality of the custom_stop_condition to the widget list. This means the rest of the graph will still be processed resulting in correct end point caches, but only widgets up to the stop condition will be added to the returned widget list. Fixes: 6742064a ("ASoC: dapm: support user-defined stop condition in dai_get_connected_widgets") Fixes: 5fdd022c ("ASoC: dpcm: play nice with CODEC<->CODEC links") Fixes: 09464974 ("ASoC: dapm: Fix to return correct path list in is_connected_ep.")

[ Upstream commit 15a78ba1 ] In compat_do_replace(), a temporary buffer is allocated through vmalloc() to hold entries copied from the user space. The buffer address is firstly saved to 'newinfo->entries', and later on assigned to 'entries_tmp'. Then the entries in this temporary buffer is copied to the internal kernel structure through compat_copy_entries(). If this copy process fails, compat_do_replace() should be terminated. However, the allocated temporary buffer is not freed on this path, leading to a memory leak. To fix the bug, free the buffer before returning from compat_do_replace(). Signed-off-by:

[ Upstream commit 405b93eb ] The current ARFS code relies on certain fields to be set in the SKB (e.g. transport_header) and extracts IP addresses and ports by custom code that parses the packet. The necessary SKB fields, however, are not always set at that point, which leads to an out-of-bounds access. Use skb_flow_dissect_flow_keys() to get the necessary information reliably, fix the out-of-bounds access and reuse the code. Fixes: 18c908e4 ("net/mlx5e: Add accelerated RFS support") Signed-off-by:

[ Upstream commit 32d3182c ] packet_sendmsg() checks tx_ring.pg_vec to decide if it must call tpacket_snd(). Problem is that the check is lockless, meaning another thread can issue a concurrent setsockopt(PACKET_TX_RING ) to flip tx_ring.pg_vec back to NULL. Given that tpacket_snd() grabs pg_vec_lock mutex, we can perform the check again to solve the race. syzbot reported : kasan: CONFIG_KASAN_INLINE enabled kasan: GPF could be caused by NULL-ptr deref or user memory access general protection fault: 0000 [#1] PREEMPT SMP KASAN CPU: 1 PID: 11429 Comm: syz-executor394 Not tainted 5.3.0-rc4+ #101 Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 01/01/2011 RIP: 0010:packet_lookup_frame+0x8d/0x270 net/packet/af_packet.c:474 Code: c1 ee 03 f7 73 0c 80 3c 0e 00 0f 85 cb 01 00 00 48 8b 0b 89 c0 4c 8d 24 c1 48 b8 00 00 00 00 00 fc ff df 4c 89 e1 48 c1 e9 03 <80> 3c 01 00 0f 85 94 01 00 00 48 8d 7b 10 4d 8b 3c 24 48 b8 00 00 RSP: 0018:ffff88809f82f7b8 EFLAGS: 00010246 RAX: dffffc0000000000 RBX: ffff8880a45c7030 RCX: 0000000000000000 RDX: 0000000000000000 RSI: 1ffff110148b8e06 RDI: ffff8880a45c703c RBP: ffff88809f82f7e8 R08: ffff888087aea200 R09: fffffbfff134ae50 R10: fffffbfff134ae4f R11: ffffffff89a5727f R12: 0000000000000000 R13: 0000000000000001 R14: ffff8880a45c6ac0 R15: 0000000000000000 FS: 00007fa04716f700(0000) GS:ffff8880ae900000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007fa04716edb8 CR3: 0000000091eb4000 CR4: 00000000001406e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace: packet_current_frame net/packet/af_packet.c:487 [inline] tpacket_snd net/packet/af_packet.c:2667 [inline] packet_sendmsg+0x590/0x6250 net/packet/af_packet.c:2975 sock_sendmsg_nosec net/socket.c:637 [inline] sock_sendmsg+0xd7/0x130 net/socket.c:657 ___sys_sendmsg+0x3e2/0x920 net/socket.c:2311 __sys_sendmmsg+0x1bf/0x4d0 net/socket.c:2413 __do_sys_sendmmsg net/socket.c:2442 [inline] __se_sys_sendmmsg net/socket.c:2439 [inline] __x64_sys_sendmmsg+0x9d/0x100 net/socket.c:2439 do_syscall_64+0xfd/0x6a0 arch/x86/entry/common.c:296 entry_SYSCALL_64_after_hwframe+0x49/0xbe Fixes: 69e3c75f ("net: TX_RING and packet mmap") Signed-off-by:

[ Upstream commit 58799865 ] The dsa framework has optional .port_mdb_{prepare,add,del} callback fields for drivers to handle multicast database entries. When adding an entry, the framework goes through a prepare phase, then a commit phase. Drivers not providing these callbacks should be detected in the prepare phase. DSA core may still bypass the bridge layer and call the dsa_port_mdb_add function directly with no prepare phase or no switchdev trans object, and the framework ends up calling an undefined .port_mdb_add callback. This results in a NULL pointer dereference, as shown in the log below. The other functions seem to be properly guarded. Do the same for .port_mdb_add in dsa_switch_mdb_add_bitmap() as well. 8<--- cut here --- Unable to handle kernel NULL pointer dereference at virtual address 00000000 pgd = (ptrval) [00000000] *pgd=00000000 Internal error: Oops: 80000005 [#1] SMP ARM Modules linked in: rtl8xxxu rtl8192cu rtl_usb rtl8192c_common rtlwifi mac80211 cfg80211 CPU: 1 PID: 134 Comm: kworker/1:2 Not tainted 5.3.0-rc1-00247-gd3519030752a #1 Hardware name: Allwinner sun7i (A20) Family Workqueue: events switchdev_deferred_process_work PC is at 0x0 LR is at dsa_switch_event+0x570/0x620 pc : [<00000000>] lr : [<c08533ec>] psr: 80070013 sp : ee871db8 ip : 00000000 fp : ee98d0a4 r10: 0000000c r9 : 00000008 r8 : ee89f710 r7 : ee98d040 r6 : ee98d088 r5 : c0f04c48 r4 : ee98d04c r3 : 00000000 r2 : ee89f710 r1 : 00000008 r0 : ee98d040 Flags: Nzcv IRQs on FIQs on Mode SVC_32 ISA ARM Segment none Control: 10c5387d Table: 6deb406a DAC: 00000051 Process kworker/1:2 (pid: 134, stack limit = 0x(ptrval)) Stack: (0xee871db8 to 0xee872000) 1da0: ee871e14 103ace2d 1dc0: 00000000 ffffffff 00000000 ee871e14 00000005 00000000 c08524a0 00000000 1de0: ffffe000 c014bdfc c0f04c48 ee871e98 c0f04c48 ee9e5000 c0851120 c014bef0 1e00: 00000000 b643aea2 ee9b4068 c08509a8 ee2bf940 ee89f710 ee871ecb 00000000 1e20: 00000008 103ace2d 00000000 c087e248 ee29c868 103ace2d 00000001 ffffffff 1e40: 00000000 ee871e98 00000006 00000000 c0fb2a50 c087e2d0 ffffffff c08523c4 1e60: ffffffff c014bdfc 00000006 c0fad2d0 ee871e98 ee89f710 00000000 c014c500 1e80: 00000000 ee89f3c0 c0f04c48 00000000 ee9e5000 c087dfb4 ee9e5000 00000000 1ea0: ee89f710 ee871ecb 00000001 103ace2d 00000000 c0f04c48 00000000 c087e0a8 1ec0: 00000000 efd9a3e0 0089f3c0 103ace2d ee89f700 ee89f710 ee9e5000 00000122 1ee0: 00000100 c087e130 ee89f700 c0fad2c8 c1003ef0 c087de4c 2e928000 c0fad2ec 1f00: c0fad2ec ee839580 ef7a62c0 ef7a9400 00000000 c087def8 c0fad2ec c01447dc 1f20: ef315640 ef7a62c0 00000008 ee839580 ee839594 ef7a62c0 00000008 c0f03d00 1f40: ef7a62d8 ef7a62c0 ffffe000 c0145b84 ffffe000 c0fb2420 c0bfaa8c 00000000 1f60: ffffe000 ee84b600 ee84b5c0 00000000 ee870000 ee839580 c0145b40 ef0e5ea4 1f80: ee84b61c c014a6f8 00000001 ee84b5c0 c014a5b0 00000000 00000000 00000000 1fa0: 00000000 00000000 00000000 c01010e8 00000000 00000000 00000000 00000000 1fc0: 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 1fe0: 00000000 00000000 00000000 00000000 00000013 00000000 00000000 00000000 [<c08533ec>] (dsa_switch_event) from [<c014bdfc>] (notifier_call_chain+0x48/0x84) [<c014bdfc>] (notifier_call_chain) from [<c014bef0>] (raw_notifier_call_chain+0x18/0x20) [<c014bef0>] (raw_notifier_call_chain) from [<c08509a8>] (dsa_port_mdb_add+0x48/0x74) [<c08509a8>] (dsa_port_mdb_add) from [<c087e248>] (__switchdev_handle_port_obj_add+0x54/0xd4) [<c087e248>] (__switchdev_handle_port_obj_add) from [<c087e2d0>] (switchdev_handle_port_obj_add+0x8/0x14) [<c087e2d0>] (switchdev_handle_port_obj_add) from [<c08523c4>] (dsa_slave_switchdev_blocking_event+0x94/0xa4) [<c08523c4>] (dsa_slave_switchdev_blocking_event) from [<c014bdfc>] (notifier_call_chain+0x48/0x84) [<c014bdfc>] (notifier_call_chain) from [<c014c500>] (blocking_notifier_call_chain+0x50/0x68) [<c014c500>] (blocking_notifier_call_chain) from [<c087dfb4>] (switchdev_port_obj_notify+0x44/0xa8) [<c087dfb4>] (switchdev_port_obj_notify) from [<c087e0a8>] (switchdev_port_obj_add_now+0x90/0x104) [<c087e0a8>] (switchdev_port_obj_add_now) from [<c087e130>] (switchdev_port_obj_add_deferred+0x14/0x5c) [<c087e130>] (switchdev_port_obj_add_deferred) from [<c087de4c>] (switchdev_deferred_process+0x64/0x104) [<c087de4c>] (switchdev_deferred_process) from [<c087def8>] (switchdev_deferred_process_work+0xc/0x14) [<c087def8>] (switchdev_deferred_process_work) from [<c01447dc>] (process_one_work+0x218/0x50c) [<c01447dc>] (process_one_work) from [<c0145b84>] (worker_thread+0x44/0x5bc) [<c0145b84>] (worker_thread) from [<c014a6f8>] (kthread+0x148/0x150) [<c014a6f8>] (kthread) from [<c01010e8>] (ret_from_fork+0x14/0x2c) Exception stack(0xee871fb0 to 0xee871ff8) 1fa0: 00000000 00000000 00000000 00000000 1fc0: 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 1fe0: 00000000 00000000 00000000 00000000 00000013 00000000 Code: bad PC value ---[ end trace 1292c61abd17b130 ]--- [<c08533ec>] (dsa_switch_event) from [<c014bdfc>] (notifier_call_chain+0x48/0x84) corresponds to $ arm-linux-gnueabihf-addr2line -C -i -e vmlinux c08533ec linux/net/dsa/switch.c:156 linux/net/dsa/switch.c:178 linux/net/dsa/switch.c:328 Fixes: e6db98db ("net: dsa: add switch mdb bitmap functions") Signed-off-by:

[ Upstream commit d595b03d ] As commit 30d8177e ("bonding: Always enable vlan tx offload") said, we should always enable bonding's vlan tx offload, pass the vlan packets to the slave devices with vlan tci, let them to handle vlan implementation. Now if encapsulation protocols like VXLAN is used, skb->encapsulation may be set, then the packet is passed to vlan device which based on bonding device. However in netif_skb_features(), the check of hw_enc_features: if (skb->encapsulation) features &= dev->hw_enc_features; clears NETIF_F_HW_VLAN_CTAG_TX/NETIF_F_HW_VLAN_STAG_TX.

[ Upstream commit 4a4d2d37 ] Commit 04f05230 ("bnx2x: Remove configured vlans as part of unload sequence."), introduced a regression in driver that as a part of VF's reload flow, VLANs created on the VF doesn't get re-configured in hardware as vlan metadata/info was not getting cleared for the VFs which causes vlan PING to stop. This patch clears the vlan metadata/info so that VLANs gets re-configured back in the hardware in VF's reload flow and PING/traffic continues for VLANs created over the VFs.

commit 656c8e9c upstream. Change ct id hash calculation to only use invariants. Currently the ct id hash calculation is based on some fields that can change in the lifetime on a conntrack entry in some corner cases. The current hash uses the whole tuple which contains an hlist pointer which will change when the conntrack is placed on the dying list resulting in a ct id change. This patch also removes the reply-side tuple and extension pointer from the hash calculation so that the ct id will will not change from initialization until confirmation.

commit b6143d10 upstream. The initial support for dynamic ftrace trampolines in modules made use of an indirect branch which loaded its target from the beginning of a special section (e71a4e1b ("arm64: ftrace: add support for far branches to dynamic ftrace")). Since no instructions were being patched, no cache maintenance was needed. However, later in be0f272b ("arm64: ftrace: emit ftrace-mod.o contents through code") this code was reworked to output the trampoline instructions directly into the PLT entry but, unfortunately, the necessary cache maintenance was overlooked. Add a call to __flush_icache_range() after writing the new trampoline instructions but before patching in the branch to the trampoline.

commit bcb44433 upstream. Storage devices which report supporting discard commands like WRITE_SAME_16 with unmap, but reject discard commands sent to the storage device. This is a clear storage firmware bug but it doesn't change the fact that should a program cause discards to be sent to a multipath device layered on this buggy storage, all paths can end up failed at the same time from the discards, causing possible I/O loss. The first discard to a path will fail with Illegal Request, Invalid field in cdb, e.g.: kernel: sd 8:0:8:19: [sdfn] tag#0 FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE kernel: sd 8:0:8:19: [sdfn] tag#0 Sense Key : Illegal Request [current] kernel: sd 8:0:8:19: [sdfn] tag#0 Add. Sense: Invalid field in cdb kernel: sd 8:0:8:19: [sdfn] tag#0 CDB: Write same(16) 93 08 00 00 00 00 00 a0 08 00 00 00 80 00 00 00 kernel: blk_update_request: critical target error, dev sdfn, sector 10487808 The SCSI layer converts this to the BLK_STS_TARGET error number, the sd device disables its support for discard on this path, and because of the BLK_STS_TARGET error multipath fails the discard without failing any path or retrying down a different path. But subsequent discards can cause path failures. Any discards sent to the path which already failed a discard ends up failing with EIO from blk_cloned_rq_check_limits with an "over max size limit" error since the discard limit was set to 0 by the sd driver for the path. As the error is EIO, this now fails the path and multipath tries to send the discard down the next path. This cycle continues as discards are sent until all paths fail. Fix this by training DM core to disable DISCARD if the underlying storage already did so. Also, fix branching in dm_done() and clone_endio() to reflect the mutually exclussive nature of the IO operations in question. Cc: stable@vger.kernel.org Reported-by:

commit 6caf0be4 upstream. On Motorola Mapphone devices such as Droid 4 there are five USB ports that do not use the same layout as Gobi 1K/2K/etc devices listed in qcserial.c. So we should use qcaux.c or option.c as noted by Dan Williams <dan.j.williams@intel.com>. As the Motorola USB serial ports have an interrupt endpoint as shown with lsusb -v, we should use option.c instead of qcaux.c as pointed out by Johan Hovold <johan@kernel.org>. The ff/ff/ff interfaces seem to always be UARTs on Motorola devices. For the other interfaces, class 0x0a (CDC Data) should not in general be added as they are typically part of a multi-interface function as noted earlier by Bjørn Mork <bjorn@mork.no>. However, looking at the Motorola mapphone kernel code, the mdm6600 0x0a class is only used for flashing the modem firmware, and there are no other interfaces. So I've added that too with more details below as it works just fine. The ttyUSB ports on Droid 4 are: ttyUSB0 DIAG, CQDM-capable ttyUSB1 MUX or NMEA, no response ttyUSB2 MUX or NMEA, no response ttyUSB3 TCMD ttyUSB4 AT-capable The ttyUSB0 is detected as QCDM capable by ModemManager. I think it's only used for debugging with ModemManager --debug for sending custom AT commands though. ModemManager already can manage data connection using the USB QMI ports that are already handled by the qmi_wwan.c driver. To enable the MUX or NMEA ports, it seems that something needs to be done additionally to enable them, maybe via the DIAG or TCMD port. It might be just a NVRAM setting somewhere, but I have no idea what NVRAM settings may need changing for that. The TCMD port seems to be a Motorola custom protocol for testing the modem and to configure it's NVRAM and seems to work just fine based on a quick test with a minimal tcmdrw tool I wrote. The voice modem AT-capable port seems to provide only partial support, and no PM support compared to the TS 27.010 based UART wired directly to the modem. The UARTs added with this change are the same product IDs as the Motorola Mapphone Android Linux kernel mdm6600_id_table. I don't have any mdm9600 based devices, so I have only tested these on mdm6600 based droid 4. Then for the class 0x0a (CDC Data) mode, the Motorola Mapphone Android Linux kernel driver moto_flashqsc.c just seems to change the port->bulk_out_size to 8K from the default. And is only used for flashing the modem firmware it seems. I've verified that flashing the modem with signed firmware works just fine with the option driver after manually toggling the GPIO pins, so I've added droid 4 modem flashing mode to the option driver. I've not added the other devices listed in moto_flashqsc.c in case they really need different port->bulk_out_size. Those can be added as they get tested to work for flashing the modem.
