[ Upstream commit 8e6e5bea ] The events defined in pmu-events JSON are parsed and added into perf tool. For fixed counters, we handle the encodings between JSON and perf by using a static array fixed[]. But the fixed[] has missed an important event "cpu_clk_unhalted.core". For example, on the Tremont platform, [root@localhost ~]# perf stat -e cpu_clk_unhalted.core -a event syntax error: 'cpu_clk_unhalted.core' \___ parser error With this patch, the event cpu_clk_unhalted.core can be parsed.

[ Upstream commit 1c703b53 ] Some a4tech mice use the 'GenericDesktop.00b8' usage to inform whether the previous wheel report was horizontal or vertical. Before c01908a1 ("HID: input: add mapping for "Toggle Display" key") this usage was being mapped to 'Relative.Misc'. After the patch it's simply ignored (usage->type == 0 & usage->code == 0). Which ultimately makes hid-a4tech ignore the WHEEL/HWHEEL selection event, as it has no usage->type. We shouldn't rely on a mapping for that usage as it's nonstandard and doesn't really map to an input event. So we bypass the mapping and make sure the custom event handling properly handles both reports. Fixes: c01908a1 ("HID: input: add mapping for "Toggle Display" key") Signed-off-by:

[ Upstream commit a0d57a55 ] In start_isoc_chain(), usb_alloc_urb() on line 1392 may fail and return NULL. At this time, fifo->iso[i].urb is assigned to NULL. Then, fifo->iso[i].urb is used at some places, such as: LINE 1405: fill_isoc_urb(fifo->iso[i].urb, ...) urb->number_of_packets = num_packets; urb->transfer_flags = URB_ISO_ASAP; urb->actual_length = 0; urb->interval = interval; LINE 1416: fifo->iso[i].urb->... LINE 1419: fifo->iso[i].urb->... Thus, possible null-pointer dereferences may occur. To fix these bugs, "continue" is added to avoid using fifo->iso[i].urb when it is NULL. These bugs are found by a static analysis tool STCheck written by us. Signed-off-by:

[ Upstream commit 1e112c35 ] The slot_width is a property for the bus while the constraint for SNDRV_PCM_HW_PARAM_SAMPLE_BITS is for the in memory format. Applying slot_width constraint to sample_bits works most of the time, but it will blacklist valid formats in some cases. With slot_width 24 we can support S24_3LE and S24_LE formats as they both look the same on the bus, but a a 24 constraint on sample_bits would not allow S24_LE as it is stored in 32bits in memory. Implement a simple hw_rule function to allow all formats which require less or equal number of bits on the bus as slot_width (if configured). Signed-off-by:

[ 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 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:

The necessary SKB fields, however, are not always set at that point, which leads to an out-of-bounds access.

[ 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 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.
