2021-08-17blk-mq: fix kernel panic during iterating over flush requestMing Lei
For fixing use-after-free during iterating over requests, we grabbed request's refcount before calling ->fn in commit 2e315dc07df0 ("blk-mq: grab rq->refcount before calling ->fn in blk_mq_tagset_busy_iter"). Turns out this way may cause kernel panic when iterating over one flush request: 1) old flush request's tag is just released, and this tag is reused by one new request, but ->rqs[] isn't updated yet 2) the flush request can be re-used for submitting one new flush command, so blk_rq_init() is called at the same time 3) meantime blk_mq_queue_tag_busy_iter() is called, and old flush request is retrieved from ->rqs[tag]; when blk_mq_put_rq_ref() is called, flush_rq->end_io may not be updated yet, so NULL pointer dereference is triggered in blk_mq_put_rq_ref(). Fix the issue by calling refcount_set(&flush_rq->ref, 1) after flush_rq->end_io is set. So far the only other caller of blk_rq_init() is scsi_ioctl_reset() in which the request doesn't enter block IO stack and the request reference count isn't used, so the change is safe.

2021-08-17virtio-net: use NETIF_F_GRO_HW instead of NETIF_F_LROJason Wang
Commit a02e8964eaf92 ("virtio-net: ethtool configurable LRO") maps LRO to virtio guest offloading features and allows the administrator to enable and disable those features via ethtool. This leads to several issues: - For a device that doesn't support control guest offloads, the "LRO" can't be disabled triggering WARN in dev_disable_lro() when turning off LRO or when enabling forwarding bridging etc. - For a device that supports control guest offloads, the guest offloads are disabled in cases of bridging, forwarding etc slowing down the traffic. Fix this by using NETIF_F_GRO_HW instead. Though the spec does not guarantee packets to be re-segmented as the original ones, we can add that to the spec, possibly with a flag for devices to differentiate between GRO and LRO. Further, we never advertised LRO historically before a02e8964eaf92 ("virtio-net: ethtool configurable LRO") and so bridged/forwarded configs effectively always relied on virtio receive offloads behaving like GRO - thus even if this breaks any configs it is at least not a regression.

2021-08-17ALSA: hda: Fix hang during shutdown due to link resetImre Deak
During system shutdown codecs may be still active, and resetting the controller->codec HW link in this state - based on the bug reporter's tests - leads to the shutdown sequence to get stuck. This happens at least on the reporter's KBL system with an ALC662 codec. For now fix the issue by skipping the link reset step.

2021-08-16vrf: Reset skb conntrack connection on VRF rcvLahav Schlesinger
To fix the "reverse-NAT" for replies. When a packet is sent over a VRF, the POST_ROUTING hooks are called twice: Once from the VRF interface, and once from the "actual" interface the packet will be sent from: 1) First SNAT: l3mdev_l3_out() -> vrf_l3_out() -> .. -> vrf_output_direct() This causes the POST_ROUTING hooks to run. 2) Second SNAT: 'ip_output()' calls POST_ROUTING hooks again. Similarly for replies, first ip_rcv() calls PRE_ROUTING hooks, and second vrf_l3_rcv() calls them again. As an example, consider the following SNAT rule: > iptables -t nat -A POSTROUTING -p udp -m udp --dport 53 -j SNAT --to-source 2.2.2.2 -o vrf_1 In this case sending over a VRF will create 2 conntrack entries. The first is from the VRF interface, which performs the IP SNAT. The second will run the SNAT, but since the "expected reply" will remain the same, conntrack randomizes the source port of the packet: e..g With a socket bound to 1.1.1.1:10000, sending to 3.3.3.3:53, the conntrack rules are: udp 17 29 src=2.2.2.2 dst=3.3.3.3 sport=10000 dport=53 packets=1 bytes=68 [UNREPLIED] src=3.3.3.3 dst=2.2.2.2 sport=53 dport=61033 packets=0 bytes=0 mark=0 use=1 udp 17 29 src=1.1.1.1 dst=3.3.3.3 sport=10000 dport=53 packets=1 bytes=68 [UNREPLIED] src=3.3.3.3 dst=2.2.2.2 sport=53 dport=10000 packets=0 bytes=0 mark=0 use=1 i.e. First SNAT IP from 1.1.1.1 --> 2.2.2.2, and second the src port is SNAT-ed from 10000 --> 61033. But when a reply is sent (3.3.3.3:53 -> 2.2.2.2:61033) only the later conntrack entry is matched: udp 17 29 src=2.2.2.2 dst=3.3.3.3 sport=10000 dport=53 packets=1 bytes=68 src=3.3.3.3 dst=2.2.2.2 sport=53 dport=61033 packets=1 bytes=49 mark=0 use=1 udp 17 28 src=1.1.1.1 dst=3.3.3.3 sport=10000 dport=53 packets=1 bytes=68 [UNREPLIED] src=3.3.3.3 dst=2.2.2.2 sport=53 dport=10000 packets=0 bytes=0 mark=0 use=1 And a "port 61033 unreachable" ICMP packet is sent back. The issue is that when PRE_ROUTING hooks are called from vrf_l3_rcv(), the skb already has a conntrack flow attached to it, which means nf_conntrack_in() will not resolve the flow again. This means only the dest port is "reverse-NATed" (61033 -> 10000) but the dest IP remains 2.2.2.2, and since the socket is bound to 1.1.1.1 it's not received. This can be verified by logging the 4-tuple of the packet in '__udp4_lib_rcv()'. The fix is then to reset the flow when skb is received on a VRF, to let conntrack resolve the flow again (which now will hit the earlier flow). To reproduce: (Without the fix "Got pkt_to_nat_port" will not be printed by running 'bash ./repro'): $ cat run_in_A1.py import logging logging.getLogger("scapy.runtime").setLevel(logging.ERROR) from scapy.all import * import argparse def get_packet_to_send(udp_dst_port, msg_name): return Ether(src='11:22:33:44:55:66', dst=iface_mac)/ \ IP(src='3.3.3.3', dst='2.2.2.2')/ \ UDP(sport=53, dport=udp_dst_port)/ \ Raw(f'{msg_name}\x0012345678901234567890') parser = argparse.ArgumentParser() parser.add_argument('-iface_mac', dest="iface_mac", type=str, required=True, help="From run_in_A3.py") parser.add_argument('-socket_port', dest="socket_port", type=str, required=True, help="From run_in_A3.py") parser.add_argument('-v1_mac', dest="v1_mac", type=str, required=True, help="From script") args, _ = parser.parse_known_args() iface_mac = args.iface_mac socket_port = int(args.socket_port) v1_mac = args.v1_mac print(f'Source port before NAT: {socket_port}') while True: pkts = sniff(iface='_v0', store=True, count=1, timeout=10) if 0 == len(pkts): print('Something failed, rerun the script :(', flush=True) break pkt = pkts[0] if not pkt.haslayer('UDP'): continue pkt_sport = pkt.getlayer('UDP').sport print(f'Source port after NAT: {pkt_sport}', flush=True) pkt_to_send = get_packet_to_send(pkt_sport, 'pkt_to_nat_port') sendp(pkt_to_send, '_v0', verbose=False) # Will not be received pkt_to_send = get_packet_to_send(socket_port, 'pkt_to_socket_port') sendp(pkt_to_send, '_v0', verbose=False) break $ cat run_in_A2.py import socket import netifaces print(f"{netifaces.ifaddresses('e00000')[netifaces.AF_LINK][0]['addr']}", flush=True) s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) s.setsockopt(socket.SOL_SOCKET, socket.SO_BINDTODEVICE, str('vrf_1' + '\0').encode('utf-8')) s.connect(('3.3.3.3', 53)) print(f'{s. getsockname()[1]}', flush=True) s.settimeout(5) while True: try: # Periodically send in order to keep the conntrack entry alive. s.send(b'a'*40) resp = s.recvfrom(1024) msg_name = resp[0].decode('utf-8').split('\0')[0] print(f"Got {msg_name}", flush=True) except Exception as e: pass $ cat repro.sh ip netns del A1 2> /dev/null ip netns del A2 2> /dev/null ip netns add A1 ip netns add A2 ip -n A1 link add _v0 type veth peer name _v1 netns A2 ip -n A1 link set _v0 up ip -n A2 link add e00000 type bond ip -n A2 link add lo0 type dummy ip -n A2 link add vrf_1 type vrf table 10001 ip -n A2 link set vrf_1 up ip -n A2 link set e00000 master vrf_1 ip -n A2 addr add 1.1.1.1/24 dev e00000 ip -n A2 link set e00000 up ip -n A2 link set _v1 master e00000 ip -n A2 link set _v1 up ip -n A2 link set lo0 up ip -n A2 addr add 2.2.2.2/32 dev lo0 ip -n A2 neigh add 1.1.1.10 lladdr 77:77:77:77:77:77 dev e00000 ip -n A2 route add 3.3.3.3/32 via 1.1.1.10 dev e00000 table 10001 ip netns exec A2 iptables -t nat -A POSTROUTING -p udp -m udp --dport 53 -j \ SNAT --to-source 2.2.2.2 -o vrf_1 sleep 5 ip netns exec A2 python3 run_in_A2.py > x & XPID=$! sleep 5 IFACE_MAC=`sed -n 1p x` SOCKET_PORT=`sed -n 2p x` V1_MAC=`ip -n A2 link show _v1 | sed -n 2p | awk '{print $2'}` ip netns exec A1 python3 run_in_A1.py -iface_mac ${IFACE_MAC} -socket_port \ ${SOCKET_PORT} -v1_mac ${SOCKET_PORT} sleep 5 kill -9 $XPID wait $XPID 2> /dev/null ip netns del A1 ip netns del A2 tail x -n 2 rm x set +x Fixes: 73e20b761acf ("net: vrf: Add support for PREROUTING rules on vrf device") Signed-off-by: Lahav Schlesinger <lschlesinger@drivenets.com> Reviewed-by: David Ahern <dsahern@kernel.org> Link: https://lore.kernel.org/r/20210815120002.2787653-1-lschlesinger@drivenets.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2021-08-16KVM: nSVM: always intercept VMLOAD/VMSAVE when nested (CVE-2021-3656)Maxim Levitsky
If L1 disables VMLOAD/VMSAVE intercepts, and doesn't enable Virtual VMLOAD/VMSAVE (currently not supported for the nested hypervisor), then VMLOAD/VMSAVE must operate on the L1 physical memory, which is only possible by making L0 intercept these instructions. Failure to do so allowed the nested guest to run VMLOAD/VMSAVE unintercepted, and thus read/write portions of the host physical memory.

In 69de4421bb4c ("drm/ttm: Initialize debugfs from ttm_global_init()"), ttm_global_init was changed so that if creation of the debugfs global root directory fails, ttm_global_init will bail out early and return an error, leading to initialization failure of DRM drivers. However, not every system will be using debugfs. On such a system, debugfs directory creation can be expected to fail, but DRM drivers must still be usable. This changes it so that if creation of TTM's debugfs root directory fails, then no biggie: keep calm and carry on.

2021-08-16bnxt_en: Add missing DMA memory barriersMichael Chan
Each completion ring entry has a valid bit to indicate that the entry contains a valid completion event. The driver's main poll loop __bnxt_poll_work() has the proper dma_rmb() to make sure the valid bit of the next entry has been checked before proceeding further. But when we call bnxt_rx_pkt() to process the RX event, the RX completion event consists of two completion entries and only the first entry has been checked to be valid. We need the same barrier after checking the next completion entry. Add missing dma_rmb() barriers in bnxt_rx_pkt() and other similar locations.

2021-08-16tipc: call tipc_wait_for_connect only when dlen is not 0Xin Long
__tipc_sendmsg() is called to send SYN packet by either tipc_sendmsg() or tipc_connect(). The difference is in tipc_connect(), it will call tipc_wait_for_connect() after __tipc_sendmsg() to wait until connecting is done. So there's no need to wait in __tipc_sendmsg() for this case. This patch is to fix it by calling tipc_wait_for_connect() only when dlen is not 0 in __tipc_sendmsg(), which means it's called by tipc_connect().

There is a known bug on BCM2711's SDHCI core integration where the controller will hang when the difference between the core clock and the bus clock is too great. Specifically this can be reproduced under the following conditions: - No SD card plugged in, polling thread is running, probing cards at 100 kHz. - BCM2711's core clock configured at 500MHz or more. So set 200 kHz as the minimum clock frequency available for that board.

2021-08-15ALSA: hda/realtek: Enable 4-speaker output for Dell XPS 15 9510 laptopKristin Paget
The 2021-model XPS 15 appears to use the same 4-speakers-on-ALC289 audio setup as the Precision models, so requires the same quirk to enable woofer output. Tested on my own 9510.

The bugs were recently found due to new platforms looking to use the ACPI NFIT "virtual" device definition, and new error injection capabilities to trigger error responses to label area requests. Ira's cleanups have been long pending, I neglected to send them earlier, and see no harm in including them now. This has all appeared in -next with no reported issues.
