The culprit was kprobe_breakpoint_ss_handler() returning DBG_HOOK_ERROR which leads to the Unexpected kernel BRK exception. Reverting commit ba090f9cafd5 ("arm64: kprobes: Remove redundant kprobe_step_ctx") seemed to fix the problem for me. Further analysis showed that kcb->kprobe_status is set to KPROBE_REENTER when the error occurs. By teaching kprobe_breakpoint_ss_handler() to handle this status I can no longer reproduce the problem.

8adc0a0 | Jin Yao | 09 December 2020, 00:58:28 UTC | perf script: Fix overrun issue for dynamically-allocated PMU type number When unpacking the event which is from dynamic PMU, the array output[OUTPUT_TYPE_MAX] may be overrun. For example, type number of SKL uncore_imc is 10, but OUTPUT_TYPE_MAX is 7 now (OUTPUT_TYPE_MAX = PERF_TYPE_MAX + 1). /* In builtin-script.c */ process_event() { unsigned int type = output_type(attr->type); if (output[type].fields == 0) return; } output[10] is overrun.

fc705fe | Adrian Hunter | 21 January 2021, 12:54:46 UTC | perf evlist: Fix id index for heterogeneous systems perf_evlist__set_sid_idx() updates perf_sample_id with the evlist map index, CPU number and TID. It is passed indexes to the evsel's cpu and thread maps, but references the evlist's maps instead. That results in using incorrect CPU numbers on heterogeneous systems. Fix it by using evsel maps. The id index (PERF_RECORD_ID_INDEX) is used by AUX area tracing when in sampling mode. Having an incorrect CPU number causes the trace data to be attributed to the wrong CPU, and can result in decoder errors because the trace data is then associated with the wrong process.

It doesn't presume that the device is present; that check will be done later, as the only caller is dm_get_device(), which does a dm_get_table_device() later on, which will properly open the device. So if the path string already _is_ in major:minor representation we can convert it directly, avoiding a recursion into the filesystem to lookup the block device. This avoids a hang in multipath_message() when the filesystem is inaccessible.

When the system restarts before all checksums have been calculated, the calculation continues where it was interrupted even if the recalculate feature is not requested the next time the dm device is set up. Disable recalculating if we use internal_hash or journal_hash with a key (e.g. HMAC) and we don't have the "legacy_recalculate" flag. This may break activation of a volume, created by an older kernel, that is not yet fully recalculated -- if this happens, the user should add the "legacy_recalculate" flag to constructor parameters.

506c203 | Takashi Iwai | 20 January 2021, 20:45:54 UTC | ALSA: usb-audio: Fix hw constraints dependencies Since the recent refactoring, it's been reported that some USB-audio devices (typically webcams) are no longer detected properly by PulseAudio. The debug session revealed that it's failing at probing by PA to try the sample rate 44.1kHz while the device has discrete sample rates other than 44.1kHz. But the puzzle was that arecord works as is, and some other devices with the discrete rates work, either. After all, this turned out to be the lack of the dependencies in a few hw constraint rules: snd_pcm_hw_rule_add() has the (variable) arguments specifying the dependent parameters, and some functions didn't set the target parameter itself as the dependencies. This resulted in an invalid parameter that could be generated only in a certain call pattern. This bug itself has been present in the code, but it didn't trigger errors just because the rules were casually avoiding such a corner case. After the recent refactoring and cleanup, however, the hw constraints work "as expected", and the problem surfaced now. For fixing the problem above, this patch adds the missing dependent parameters to each snd_pcm_hw_rule() call.

584b7cf | Alban Bedel | 19 January 2021, 14:06:38 UTC | net: mscc: ocelot: Fix multicast to the CPU port Multicast entries in the MAC table use the high bits of the MAC address to encode the ports that should get the packets. But this port mask does not work for the CPU port, to receive these packets on the CPU port the MAC_CPU_COPY flag must be set. Because of this IPv6 was effectively not working because neighbor solicitations were never received. This was not apparent before commit 9403c158 (net: mscc: ocelot: support IPv4, IPv6 and plain Ethernet mdb entries) as the IPv6 entries were broken so all incoming IPv6 multicast was then treated as unknown and flooded on all ports. To fix this problem rework the ocelot_mact_learn() to set the MAC_CPU_COPY flag when a multicast entry that target the CPU port is added. For this we have to read back the ports endcoded in the pseudo MAC address by the caller. It is not a very nice design but that avoid changing the callers and should make backporting easier.

c89dffc | Kuniyuki Iwashima | 18 January 2021, 05:59:20 UTC | tcp: Fix potential use-after-free due to double kfree() Receiving ACK with a valid SYN cookie, cookie_v4_check() allocates struct request_sock and then can allocate inet_rsk(req)->ireq_opt. After that, tcp_v4_syn_recv_sock() allocates struct sock and copies ireq_opt to inet_sk(sk)->inet_opt. Normally, tcp_v4_syn_recv_sock() inserts the full socket into ehash and sets NULL to ireq_opt. Otherwise, tcp_v4_syn_recv_sock() has to reset inet_opt by NULL and free the full socket. The commit 01770a1661657 ("tcp: fix race condition when creating child sockets from syncookies") added a new path, in which more than one cores create full sockets for the same SYN cookie. Currently, the core which loses the race frees the full socket without resetting inet_opt, resulting in that both sock_put() and reqsk_put() call kfree() for the same memory: sock_put sk_free __sk_free sk_destruct __sk_destruct sk->sk_destruct/inet_sock_destruct kfree(rcu_dereference_protected(inet->inet_opt, 1)); reqsk_put reqsk_free __reqsk_free req->rsk_ops->destructor/tcp_v4_reqsk_destructor kfree(rcu_dereference_protected(inet_rsk(req)->ireq_opt, 1)); Calling kmalloc() between the double kfree() can lead to use-after-free, so this patch fixes it by setting NULL to inet_opt before sock_put(). As a side note, this kind of issue does not happen for IPv6. This is because tcp_v6_syn_recv_sock() clones both ipv6_opt and pktopts which correspond to ireq_opt in IPv4.

b160c28 | Eric Dumazet | 19 January 2021, 16:49:00 UTC | tcp: do not mess with cloned skbs in tcp_add_backlog() Heiner Kallweit reported that some skbs were sent with the following invalid GSO properties : - gso_size > 0 - gso_type == 0 This was triggerring a WARN_ON_ONCE() in rtl8169_tso_csum_v2. Juerg Haefliger was able to reproduce a similar issue using a lan78xx NIC and a workload mixing TCP incoming traffic and forwarded packets. The problem is that tcp_add_backlog() is writing over gso_segs and gso_size even if the incoming packet will not be coalesced to the backlog tail packet. While skb_try_coalesce() would bail out if tail packet is cloned, this overwriting would lead to corruptions of other packets cooked by lan78xx, sharing a common super-packet. The strategy used by lan78xx is to use a big skb, and split it into all received packets using skb_clone() to avoid copies. The drawback of this strategy is that all the small skb share a common struct skb_shared_info. This patch rewrites TCP gso_size/gso_segs handling to only happen on the tail skb, since skb_try_coalesce() made sure it was not cloned.

8d2b51b | Guillaume Nault | 16 January 2021, 10:44:22 UTC | udp: mask TOS bits in udp_v4_early_demux() udp_v4_early_demux() is the only function that calls ip_mc_validate_source() with a TOS that hasn't been masked with IPTOS_RT_MASK. This results in different behaviours for incoming multicast UDPv4 packets, depending on if ip_mc_validate_source() is called from the early-demux path (udp_v4_early_demux) or from the regular input path (ip_route_input_noref). ECN would normally not be used with UDP multicast packets, so the practical consequences should be limited on that side. However, IPTOS_RT_MASK is used to also masks the TOS' high order bits, to align with the non-early-demux path behaviour. Reproducer: Setup two netns, connected with veth: $ ip netns add ns0 $ ip netns add ns1 $ ip -netns ns0 link set dev lo up $ ip -netns ns1 link set dev lo up $ ip link add name veth01 netns ns0 type veth peer name veth10 netns ns1 $ ip -netns ns0 link set dev veth01 up $ ip -netns ns1 link set dev veth10 up $ ip -netns ns0 address add 192.0.2.10 peer 192.0.2.11/32 dev veth01 $ ip -netns ns1 address add 192.0.2.11 peer 192.0.2.10/32 dev veth10 In ns0, add route to multicast address 224.0.2.0/24 using source address 198.51.100.10: $ ip -netns ns0 address add 198.51.100.10/32 dev lo $ ip -netns ns0 route add 224.0.2.0/24 dev veth01 src 198.51.100.10 In ns1, define route to 198.51.100.10, only for packets with TOS 4: $ ip -netns ns1 route add 198.51.100.10/32 tos 4 dev veth10 Also activate rp_filter in ns1, so that incoming packets not matching the above route get dropped: $ ip netns exec ns1 sysctl -wq net.ipv4.conf.veth10.rp_filter=1 Now try to receive packets on 224.0.2.11: $ ip netns exec ns1 socat UDP-RECVFROM:1111,ip-add-membership=224.0.2.11:veth10,ignoreeof - In ns0, send packet to 224.0.2.11 with TOS 4 and ECT(0) (that is, tos 6 for socat): $ echo test0 | ip netns exec ns0 socat - UDP-DATAGRAM:224.0.2.11:1111,bind=:1111,tos=6 The "test0" message is properly received by socat in ns1, because early-demux has no cached dst to use, so source address validation is done by ip_route_input_mc(), which receives a TOS that has the ECN bits masked. Now send another packet to 224.0.2.11, still with TOS 4 and ECT(0): $ echo test1 | ip netns exec ns0 socat - UDP-DATAGRAM:224.0.2.11:1111,bind=:1111,tos=6 The "test1" message isn't received by socat in ns1, because, now, early-demux has a cached dst to use and calls ip_mc_validate_source() immediately, without masking the ECN bits.

b425e24 | Maxim Mikityanskiy | 18 January 2021, 16:03:33 UTC | xsk: Clear pool even for inactive queues The number of queues can change by other means, rather than ethtool. For example, attaching an mqprio qdisc with num_tc > 1 leads to creating multiple sets of TX queues, which may be then destroyed when mqprio is deleted. If an AF_XDP socket is created while mqprio is active, dev->_tx[queue_id].pool will be filled, but then real_num_tx_queues may decrease with deletion of mqprio, which will mean that the pool won't be NULLed, and a further increase of the number of TX queues may expose a dangling pointer. To avoid any potential misbehavior, this commit clears pool for RX and TX queues, regardless of real_num_*_queues, still taking into consideration num_*_queues to avoid overflows.

2b73649 | Kai-Heng Feng | 19 January 2021, 15:21:43 UTC | ALSA: hda: Balance runtime/system PM if direct-complete is disabled After hibernation, HDA controller can't be runtime-suspended after commit 215a22ed31a1 ("ALSA: hda: Refactor codjc PM to use direct-complete optimization"), which enables direct-complete for HDA codec. The HDA codec driver didn't expect direct-complete will be disabled after it returns a positive value from prepare() callback. However, there are some places that PM core can disable direct-complete. For instance, system hibernation or when codec has subordinates like LEDs. So if the codec is prepared for direct-complete but PM core still calls codec's suspend or freeze callback, partially revert the commit and take the original approach, which uses pm_runtime_force_*() helpers to ensure PM refcount are balanced. Meanwhile, still keep prepare() and complete() callbacks to enable direct-complete and request a resume for jack detection, respectively. Reported-by: Kenneth R.

Some callers expect this behavior and append a terminator to returned string. In particular: arch/powerpc/xmon/xmon.c:dump_log_buf() arch/um/kernel/kmsg_dump.c:kmsg_dumper_stdout() msg_print_text() has been replaced by record_print_text(), which currently fills the full size of the buffer. This causes a buffer overflow for the above callers. Change record_print_text() so that it will only use size-1 bytes for text data. Also, for paranoia sakes, add a terminator after the text data. And finally, document this behavior so that it is clear that only size-1 bytes are used and a terminator is added.

The number of unanswered zero-window probes (tcp_probes_out) is reset to zero with incoming acks irrespective of the window size, as described in tcp_probe_timer(): RFC 1122 4.2.2.17 requires the sender to stay open indefinitely as long as the receiver continues to respond probes. We support this by default and reset icsk_probes_out with incoming ACKs. This counter, however, is the wrong one to be used in calculating the duration that the window remains closed and data remain untransmitted. Thanks to Jonathan Maxwell <jmaxwell37@gmail.com> for diagnosing the actual issue. In this patch a new timestamp is introduced for the socket in order to track the elapsed time for the zero-window probes that have not been answered with any non-zero window ack.
