In case multiple subflows race to update the mptcp-level receive window, the subflow losing the race should use the window value provided by the "winning" subflow to update it's own tcp-level rcv_wnd. To such goal, the current code bogusly uses the mptcp-level rcv_wnd value as observed before the update attempt. On unlucky circumstances that may lead to TCP-level window shrinkage, and stall the other end. Address the issue feeding to the rcv wnd update the correct value.

According to the NAPI documentation networking/napi.rst, Rx specific APIs like page pool and XDP cannot be used at all when budget is 0. skb Tx processing should happen regardless of the budget. Stop NAPI polling after Tx processing and skip Rx processing if budget is 0. Signed-off-by:

According to the NAPI documentation networking/napi.rst, for the ethtool API a channel is a IRQ/NAPI which services queues of a given type. tsnep uses a single IRQ/NAPI instance for every TX/RX queue pair. Therefore, combined channels shall be returned instead of separate tx/rx channels. Signed-off-by:

Struct hsr_sup_tlv describes HW layout and therefore it needs a __packed attribute to ensure the compiler does not add any padding. Due to the size and __packed attribute of the structs that use hsr_sup_tlv it has no functional impact. Add __packed to struct hsr_sup_tlv. Signed-off-by:

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.

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.

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: -

Alex reported that running ssh over IPv6 does not work with Thunderbolt/USB4 networking driver. The reason for that is that driver should call skb_is_gso() before calling skb_is_gso_v6(), and it should not return false after calculates the checksum successfully. This probably was a copy paste error from the original driver where it was done properly. Reported-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. For example: hdr->message_length takes the wrong value (0xffff) and it does not replicate real header length. In this case, 'nhoff' value was overridden and the PTP header was badly dissected. This leads to a kernel crash. net/core: flow_dissector net/core flow dissector nhoff = 0x0000000e net/core flow dissector hdr->message_length = 0x0000ffff net/core flow dissector nhoff = 0x0001000d (u16 overflow) ... skb linear: 00000000: 00 a0 c9 00 00 00 00 a0 c9 00 00 00 88 skb frag: 00000000: f7 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff Using the size of the ptp_header struct will allow the corrected calculation of the nhoff value. net/core flow dissector nhoff = 0x0000000e net/core flow dissector nhoff = 0x00000030 (sizeof ptp_header) ... skb linear: 00000000: 00 a0 c9 00 00 00 00 a0 c9 00 00 00 88 f7 ff ff skb linear: 00000010: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff skb linear: 00000020: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff skb frag: 00000000: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff Kernel trace: [ 74.984279] ------------[ cut here ]------------ [ 74.989471] kernel BUG at include/linux/skbuff.h:2440!

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
