The attach callback of struct Qdisc_ops is used by only a few qdiscs: mq, mqprio and htb. qdisc_graft() contains the following logic (pseudocode): if (!qdisc->ops->attach) { if (ingress) do ingress stuff; else do egress stuff; } if (!ingress) { ... if (qdisc->ops->attach) qdisc->ops->attach(qdisc); } else { ... } As we see, the attach callback is not called if the qdisc is being attached to ingress (TC_H_INGRESS). That wasn't a problem for mq and mqprio, since they contain a check that they are attached to TC_H_ROOT, and they can't be attached to TC_H_INGRESS anyway. However, the commit cited below added the attach callback to htb. It is needed for the hardware offload, but in the non-offload mode it simulates the "do egress stuff" part of the pseudocode above. The problem is that when htb is attached to ingress, neither "do ingress stuff" nor attach() is called. It results in an inconsistency, and the following message is printed to dmesg: unregister_netdevice: waiting for lo to become free. Usage count = 2 This commit addresses the issue by running "do ingress stuff" in the ingress flow even in the attach callback is present, which is fine, because attach isn't going to be called afterwards. The bug was found by syzbot and reported by Eric. Fixes: d03b195b ("sch_htb: Hierarchical QoS hardware offload") Signed-off-by:Maxim Mikityanskiy <maximmi@nvidia.com> Reported-by:

While experimenting with FOU encapsulation Amir noticed that encapsulated IPv6 traffic fails to be delivered, if the peer IP address is configured locally. It can be easily verified by creating a sit interface like below: $ sudo ip link add name fou_test type sit remote 127.0.0.1 encap fou encap-sport auto encap-dport 1111 $ sudo ip link set fou_test up and sending some IPv4 and IPv6 traffic to it $ ping -I fou_test -c 1 1.1.1.1 $ ping6 -I fou_test -c 1 fe80::d0b0:dfff:fe4c:fcbc "tcpdump -i any udp dst port 1111" will confirm that only the first IPv4 ping was encapsulated and attempted to be delivered. This seems like a limitation: for example, in a cloud environment the "peer" service may be arbitrarily scheduled on any server within the cluster, where all nodes are trying to send encapsulated traffic. And the unlucky node will not be able to. Moreover, delivering encapsulated IPv4 traffic locally is allowed. But I may not have all the context about this restriction and this code predates the observable git history. Reported-by:

In Linux bonding scenario, one packet is copied to several copies and sent by all slave device of bond0 in mode 3(broadcast mode). The mode 3 xmit function bond_xmit_broadcast() only ueses the last slave device's tx result as the final result. In this case, if the last slave device is down, then it always return NET_XMIT_DROP, even though the other slave devices xmit success. It may cause the tx statistics error, and cause the application (e.g. scp) consider the network is unreachable. For example, use the following command to configure server A. echo 3 > /sys/class/net/bond0/bonding/mode ifconfig bond0 up ifenslave bond0 eth0 eth1 ifconfig bond0 192.168.1.125 ifconfig eth0 up ifconfig eth1 down The slave device eth0 and eth1 are connected to server B(192.168.1.107). Run the ping 192.168.1.107 -c 3 -i 0.2 command, the following information is displayed. PING 192.168.1.107 (192.168.1.107) 56(84) bytes of data. 64 bytes from 192.168.1.107: icmp_seq=1 ttl=64 time=0.077 ms 64 bytes from 192.168.1.107: icmp_seq=2 ttl=64 time=0.056 ms 64 bytes from 192.168.1.107: icmp_seq=3 ttl=64 time=0.051 ms 192.168.1.107 ping statistics 0 packets transmitted, 3 received Actually, the slave device eth0 of the bond successfully sends three ICMP packets, but the result shows that 0 packets are transmitted. Also if we use scp command to get remote files, the command end with the following printings. ssh_exchange_identification: read: Connection timed out So this patch modifies the bond_xmit_broadcast to return NET_XMIT_SUCCESS if one slave device in the bond sends packets successfully. If all slave devices send packets fail, the discarded packets stats is increased. The skb is released when there is no slave device in the bond or the last slave device is down.

I left one dev_put() in br_add_if() error path and sure enough syzbot found its way. As the tracker is allocated in new_nbp(), we must make sure to properly free it. We have to call dev_put_track(dev, &p->dev_tracker) before @p object is freed, of course. This is not an issue because br_add_if() owns a reference on @dev.

Alex Elder says: ==================== net: ipa: fix two replenish bugs This series contains two fixes for bugs in the IPA receive buffer replenishing code. The (new) second patch defines a bitmap to represent endpoint the replenish enabled flag. Its purpose is to prepare for the third patch, which adds an additional flag. Version 2 of this series uses bitmap operations in the second bug fix rather than an atomic variable, as suggested by Jakub. ==================== Signed-off-by: -
Alex Elder authored
We have seen cases where an endpoint RX completion interrupt arrives while replenishing for the endpoint is underway. This causes another instance of replenishing to begin as part of completing the receive transaction. If this occurs it can lead to transaction corruption. Use a new flag to ensure only one replenish instance for an endpoint executes at a time. Fixes: 84f9bd12 ("soc: qcom: ipa: IPA endpoints") Signed-off-by:

Alex Elder authored
In ipa_endpoint_replenish(), if an error occurs when attempting to replenish a receive buffer, we just quit and try again later. In that case we increment the backlog count to reflect that the attempt was unsuccessful. Then, if the add_one flag was true we increment the backlog again. This second increment is not included in the backlog local variable though, and its value determines whether delayed work should be scheduled. This is a bug. Fix this by determining whether 1 or 2 should be added to the backlog before adding it in a atomic_add_return() call. Reviewed-by:

syzbot was able to trigger this warning from new_slab() /* * All existing users of the __GFP_NOFAIL are blockable, so warn * of any new users that actually require GFP_NOWAIT */ if (WARN_ON_ONCE(!can_direct_reclaim)) goto fail; Indeed, we should use __GFP_NOFAIL if direct reclaim is possible. Hopefully in the future we will be able to use SLAB_NOFAILSLAB option so that syzbot can benefit from full ref_tracker even in the presence of memory fault injections.

It appears that there are some buffer overflows in EVT_TRANSACTION. This happens because the length parameters that are passed to memcpy come directly from skb->data and are not guarded in any way. Signed-off-by:

Guillaume Nault says: ==================== ipv4: Fix accidental RTO_ONLINK flags passed to ip_route_output_key_hash() The IPv4 stack generally uses the last bit of ->flowi4_tos as a flag indicating link scope for route lookups (RTO_ONLINK). Therefore, we have to be careful when copying a TOS value to ->flowi4_tos. In particular, the ->tos field of IPv4 packets may have this bit set because of ECN. Also tunnel keys generally accept any user value for the tos. This series fixes several places where ->flowi4_tos was set from non-sanitised values and the flowi4 structure was later used by ip_route_output_key_hash(). Note that the IPv4 stack usually clears the RTO_ONLINK bit using RT_TOS(). However this macro is based on an obsolete interpretation of the old IPv4 TOS field (RFC 1349) and clears the three high order bits too. Since we don't need to clear these bits and since it doesn't make sense to clear only one of the ECN bits, this patch series uses INET_ECN_MASK instead. All patches were compile tested only. ==================== Link: https://lore.kernel.org/r/cover.1641821242.git.gnault@redhat.comSigned-off-by:

Similar to commit 94e22389 ("xfrm4: strip ECN bits from tos field"), clear the ECN bits from iph->tos when setting ->flowi4_tos. This ensures that the last bit of ->flowi4_tos is cleared, so ip_route_output_key_hash() isn't going to restrict the scope of the route lookup. Use ~INET_ECN_MASK instead of IPTOS_RT_MASK, because we have no reason to clear the high order bits. Found by code inspection, compile tested only.

Commit 2c865a8a ("netfilter: nf_tables: add rule blob layout") never initialized the new 'data_size' variable. I'm not sure how it ever worked, but it might have worked almost by accident - gcc seems to occasionally miss these kinds of 'variable used uninitialized' situations, but I've seen it do so because it ended up zero-initializing them due to some other simplification. But clang is very unhappy about it all, and correctly reports net/netfilter/nf_tables_api.c:8278:4: error: variable 'data_size' is uninitialized when used here [-Werror,-Wuninitialized] data_size += sizeof(*prule) + rule->dlen; ^~~~~~~~~ net/netfilter/nf_tables_api.c:8263:30: note: initialize the variable 'data_size' to silence this warning unsigned int size, data_size; ^ = 0 1 error generated. and this fix just initializes 'data_size' to zero before the loop.
