While adding support for parsing the redbox supervision frames, the author added `pull_size' and `total_pull_size' to track the amount of bytes that were pulled from the skb during while parsing the skb so it can be reverted/ pushed back at the end. In the process probably copy&paste error occurred and for the HSRv1 case the ethhdr was used instead of the hsr_tag. Later the hsr_tag was used instead of hsr_sup_tag. The later error didn't matter because both structs have the size so HSRv0 was still working. It broke however HSRv1 parsing because struct ethhdr is larger than struct hsr_tag. Reinstate the old pulling flow and pull first ethhdr, hsr_tag in v1 case followed by hsr_sup_tag.

Currently, we assume the skb is associated with a device before calling __ip_options_compile, which is not always the case if it is re-routed by ipvs. When skb->dev is NULL, dev_net(skb->dev) will become null-dereference. This patch adds a check for the edge case and switch to use the net_device from the rtable when skb->dev is NULL. Fixes: ed0de45a ("ipv4: recompile ip options in ipv4_link_failure") Suggested-by:

When an XDP redirect happens before the link is ready, that transmission will not finish and will timeout, causing an adapter reset. If the redirects do not stop, the adapter will not stop resetting. Wait for the driver to signal that there's a carrier before allowing transmissions to proceed. Previous code was relying that when __IGC_DOWN is cleared, the NIC is ready to transmit as all the queues are ready, what happens is that the carrier presence will only be signaled later, after the watchdog workqueue has a chance to run. And during this interval (between clearing __IGC_DOWN and the watchdog running) if any transmission happens the timeout is emitted (detected by igc_tx_timeout()) which causes the reset, with the potential for the infinite loop. Fixes: 4ff32036 ("igc: Add support for XDP_REDIRECT action") Reported-by:

The ionic device supports a maximum buffer length of 16 bits (see ionic_rxq_desc or ionic_rxq_sg_elem). When adding new buffers to the receive rings, the function ionic_rx_fill() uses 16bit math when calculating the number of pages to allocate for an RX descriptor, given the interface's MTU setting. If the system PAGE_SIZE >= 64KB, and the buf_info->page_offset is 0, the remain_len value will never decrement from the original MTU value and the frag_len value will always be 0, causing additional pages to be allocated as scatter- gather elements unnecessarily. A similar math issue exists in ionic_rx_frags(), but no failures have been observed here since a 64KB page should not normally require any scatter-gather elements at any legal Ethernet MTU size.

bpf_nf testcase fails on s390x: bpf_skb_ct_lookup() cannot find the entry that was added by bpf_ct_insert_entry() within the same BPF function. The reason is that this entry is deleted by nf_ct_gc_expired(). The CT timeout starts ticking after the CT confirmation; therefore nf_conn.timeout is initially set to the timeout value, and __nf_conntrack_confirm() sets it to the deadline value. bpf_ct_insert_entry() sets IPS_CONFIRMED_BIT, but does not adjust the timeout, making its value meaningless and causing false positives. Fix the problem by making bpf_ct_insert_entry() adjust the timeout, like __nf_conntrack_confirm().

If port VLAN is configured on a VF then any other VLANs on top of this VF are broken. During i40e_ndo_set_vf_port_vlan() call the i40e driver reset the VF and iavf driver asks PF (using VIRTCHNL_OP_GET_VF_RESOURCES) for VF capabilities but this reset occurs too early, prior setting of vf->info.pvid field and because this field can be zero during i40e_vc_get_vf_resources_msg() then VIRTCHNL_VF_OFFLOAD_VLAN capability is reported to iavf driver. This is wrong because iavf driver should not report VLAN offloading capability when port VLAN is configured as i40e does not support QinQ offloading. Fix the issue by moving VF reset after setting of vf->port_vlan_id field.

netfilter pull request 23-09-13 ==================== The following patchset contains Netfilter fixes for net: 1) Do not permit to remove rules from chain binding, otherwise double rule release is possible, triggering UaF. This rule deletion support does not make sense and userspace does not use this. Problem exists since the introduction of chain binding support. 2) rbtree GC worker only collects the elements that have expired. This operation is not destructive, therefore, turn write into read spinlock to avoid datapath contention due to GC worker run. This was not fixed in the recent GC fix batch in the 6.5 cycle. 3) pipapo set backend performs sync GC, therefore, catchall elements must use sync GC queue variant. This bug was introduced in the 6.5 cycle with the recent GC fixes. 4) Stop GC run if memory allocation fails in pipapo set backend, otherwise access to NULL pointer to GC transaction object might occur. This bug was introduced in the 6.5 cycle with the recent GC fixes. 5) rhash GC run uses an iterator that might hit EAGAIN to rewind, triggering double-collection of the same element. This bug was introduced in the 6.5 cycle with the recent GC fixes. 6) Do not permit to remove elements in anonymous sets, this type of sets are populated once and then bound to rules. This fix is similar to the chain binding patch coming first in this batch. API permits since the very beginning but it has no use case from userspace. ==================== Signed-off-by: -

When a PTP ethernet raw frame with a size of more than 256 bytes followed by a 0xff pattern is sent to __skb_flow_dissect, nhoff value calculation is wrong.

Inject fault while probing kunit-example-test.ko, the rule which is allocated by kzalloc in vcap_alloc_rule(), the field which is allocated by kzalloc in vcap_rule_add_action() and vcap_rule_add_key() is not freed, and it cause the memory leaks below. Use vcap_free_rule() to free them as other drivers do it. And since the return rule of test_vcap_xn_rule_creator() is not used, remove it and switch to void. unreferenced object 0xffff058383334240 (size 192): comm "kunit_try_catch", pid 309, jiffies

syzkaller found a memory leak in kcm_sendmsg(), and commit c821a88b ("kcm: Fix memory leak in error path of kcm_sendmsg()") suppressed it by updating kcm_tx_msg(head)->last_skb if partial data is copied so that the following sendmsg() will resume from the skb. However, we cannot know how many bytes were copied when we get the error. Thus, we could mess up the MSG_MORE queue. When kcm_sendmsg() fails for SOCK_DGRAM, we should purge the queue as we do so for UDP by udp_flush_pending_frames(). Even without this change, when the error occurred, the following sendmsg() resumed from a wrong skb and the queue was messed up. However, we have yet to get such a report, and only syzkaller stumbled on it. So, this can be changed safely. Note this does not change SOCK_SEQPACKET behaviour.

Pull genpm / pmdomain rename from Ulf Hansson: "This renames the genpd subsystem to pmdomain. As discussed on LKML, using 'genpd' as the name of a subsystem isn't very self-explanatory and the acronym itself that means Generic PM Domain, is known only by a limited group of people. The suggestion to improve the situation is to rename the subsystem to 'pmdomain', which there seems to be a good consensus around using. Ideally it should indicate that its purpose is to manage Power Domains or 'PM domains' as we often also use within the Linux Kernel terminology" * tag 'pmdomain-v6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/linux-pm: pmdomain: Rename the genpd subsystem to pmdomain

The value in idx and the number of rules handled in that particular __nf_tables_dump_rules() call is not identical. The former is a cursor to pick up from if multiple netlink messages are needed, so its value is ever increasing. Fixing this is not just a matter of subtracting s_idx from it, though: When resetting rules in multiple chains, __nf_tables_dump_rules() is called for each and cb->args[0] is not adjusted in between. Introduce a dedicated counter to record the number of rules reset in this call in a less confusing way. While being at it, prevent the direct return upon buffer exhaustion: Any rules previously dumped into that skb would evade audit logging otherwise.
