2024-05-28wifi: ath12k: fix race due to setting ATH12K_FLAG_EXT_IRQ_ENABLED too earlyBaochen Qiang
Commit 5082b3e3027e ("wifi: ath11k: fix race due to setting ATH11K_FLAG_EXT_IRQ_ENABLED too early") fixes a race in ath11k driver. Since ath12k shares the same logic as ath11k, currently the race also exists in ath12k: in ath12k_pci_ext_irq_enable(), ATH12K_FLAG_EXT_IRQ_ENABLED is set before NAPI is enabled. In cases where only one MSI vector is allocated, this results in a race condition: after ATH12K_FLAG_EXT_IRQ_ENABLED is set but before NAPI enabled, CE interrupt breaks in. Since IRQ is shared by CE and data path, ath12k_pci_ext_interrupt_handler() is also called where we call disable_irq_nosync() to disable IRQ. Then napi_schedule() is called but it does nothing because NAPI is not enabled at that time, meaning that ath12k_pci_ext_grp_napi_poll() will never run, so we have no chance to call enable_irq() to enable IRQ back. Since IRQ is shared, all interrupts are disabled and we would finally get no response from target. So port ath11k fix here, this is done by setting ATH12K_FLAG_EXT_IRQ_ENABLED after all NAPI and IRQ work are done. With the fix, we are sure that by the time ATH12K_FLAG_EXT_IRQ_ENABLED is set, NAPI is enabled. Note that the fix above also introduce some side effects: if ath12k_pci_ext_interrupt_handler() breaks in after NAPI enabled but before ATH12K_FLAG_EXT_IRQ_ENABLED set, nothing will be done by the handler this time, the work will be postponed till the next time the IRQ fires. This is found during code review.

2024-05-27ice: fix accounting if a VLAN already existsJacob Keller
The ice_vsi_add_vlan() function is used to add a VLAN filter for the target VSI. This function prepares a filter in the switch table for the given VSI. If it succeeds, the vsi->num_vlan counter is incremented. It is not considered an error to add a VLAN which already exists in the switch table, so the function explicitly checks and ignores -EEXIST. The vsi->num_vlan counter is still incremented. This seems incorrect, as it means we can double-count in the case where the same VLAN is added twice by the caller. The actual table will have one less filter than the count. The ice_vsi_del_vlan() function similarly checks and handles the -ENOENT condition for when deleting a filter that doesn't exist. This flow only decrements the vsi->num_vlan if it actually deleted a filter. The vsi->num_vlan counter is used only in a few places, primarily related to tracking the number of non-zero VLANs. If the vsi->num_vlans gets out of sync, then ice_vsi_num_non_zero_vlans() will incorrectly report more VLANs than are present, and ice_vsi_has_non_zero_vlans() could return true potentially in cases where there are only VLAN 0 filters left. Fix this by only incrementing the vsi->num_vlan in the case where we actually added an entry, and not in the case where the entry already existed.

2024-05-27idpf: don't enable NAPI and interrupts prior to allocating Rx buffersAlexander Lobakin
Currently, idpf enables NAPI and interrupts prior to allocating Rx buffers. This may lead to frame loss (there are no buffers to place incoming frames) and even crashes on quick ifup-ifdown. Interrupts must be enabled only after all the resources are here and available. Split interrupt init into two phases: initialization and enabling, and perform the second only after the queues are fully initialized. Note that we can't just move interrupt initialization down the init process, as the queues must have correct a ::q_vector pointer set and NAPI already added in order to allocate buffers correctly. Also, during the deinit process, disable HW interrupts first and only then disable NAPI. Otherwise, there can be a HW event leading to napi_schedule(), but the NAPI will already be unavailable.

2024-05-27net: micrel: Fix lan8841_config_intr after getting out of sleep modeHoratiu Vultur
When the interrupt is enabled, the function lan8841_config_intr tries to clear any pending interrupts by reading the interrupt status, then checks the return value for errors and then continue to enable the interrupt. It has been seen that once the system gets out of sleep mode, the interrupt status has the value 0x400 meaning that the PHY detected that the link was in low power. That is correct value but the problem is that the check is wrong. We try to check for errors but we return an error also in this case which is not an error. Therefore fix this by returning only when there is an error.

LED Select (LED_SEL) bit in the LED General Purpose IO Configuration register is used to determine the functionality of external LED pins (Speed Indicator, Link and Activity Indicator, Full Duplex Link Indicator). The default value for this bit is 0 when no EEPROM is present. If a EEPROM is present, the default value is the value of the LED Select bit in the Configuration Flags of the EEPROM. A USB Reset or Lite Reset (LRST) will cause this bit to be restored to the image value last loaded from EEPROM, or to be set to 0 if no EEPROM is present. While configuring the dual purpose GPIO/LED pins to LED outputs in the LED General Purpose IO Configuration register, the LED_SEL bit is changed as 0 and resulting the configured value from the EEPROM is cleared. The issue is fixed by using read-modify-write approach.

2024-05-27enic: Validate length of nl attributes in enic_set_vf_portRoded Zats
enic_set_vf_port assumes that the nl attribute IFLA_PORT_PROFILE is of length PORT_PROFILE_MAX and that the nl attributes IFLA_PORT_INSTANCE_UUID, IFLA_PORT_HOST_UUID are of length PORT_UUID_MAX. These attributes are validated (in the function do_setlink in rtnetlink.c) using the nla_policy ifla_port_policy. The policy defines IFLA_PORT_PROFILE as NLA_STRING, IFLA_PORT_INSTANCE_UUID as NLA_BINARY and IFLA_PORT_HOST_UUID as NLA_STRING. That means that the length validation using the policy is for the max size of the attributes and not on exact size so the length of these attributes might be less than the sizes that enic_set_vf_port expects. This might cause an out of bands read access in the memcpys of the data of these attributes in enic_set_vf_port.

2024-05-25netkit: Fix pkt_type override upon netkit pass verdictDaniel Borkmann
When running Cilium connectivity test suite with netkit in L2 mode, we found that compared to tcx a few tests were failing which pushed traffic into an L7 proxy sitting in host namespace. The problem in particular is around the invocation of eth_type_trans() in netkit. In case of tcx, this is run before the tcx ingress is triggered inside host namespace and thus if the BPF program uses the bpf_skb_change_type() helper the newly set type is retained. However, in case of netkit, the late eth_type_trans() invocation overrides the earlier decision from the BPF program which eventually leads to the test failure. Instead of eth_type_trans(), split out the relevant parts, meaning, reset of mac header and call to eth_skb_pkt_type() before the BPF program is run in order to have the same behavior as with tcx, and refactor a small helper called eth_skb_pull_mac() which is run in case it's passed up the stack where the mac header must be pulled. With this all connectivity tests pass.

2024-05-25wifi: ath12k: fix firmware crash during reo reinjectP Praneesh
When handling fragmented packets, the ath12k driver reassembles each fragment into a normal packet and then reinjects it into the HW ring. However, a firmware crash occurs during this reinjection process. The issue arises because the driver populates peer metadata in reo_ent_ring->queue_addr_lo, while the firmware expects the physical address obtained from the corresponding peer’s queue descriptor. Fix it by filling peer's queue descriptor's physical address in queue_addr_lo.

The monitor ring and the reo reinject ring share the same ring mask index.

Since monitor support is not yet enabled in ath12k, the ring mask for the monitor ring should be removed.

2024-05-25wifi: ath12k: change DMA direction while mapping reinjected packetsP Praneesh
For fragmented packets, ath12k reassembles each fragment as a normal packet and then reinjects it into HW ring. In this case, the DMA direction should be DMA_TO_DEVICE, not DMA_FROM_DEVICE. Otherwise, an invalid payload may be reinjected into the HW and subsequently delivered to the host. Given that arbitrary memory can be allocated to the skb buffer, knowledge about the data contained in the reinjected buffer is lacking. Consequently, there’s a risk of private information being leaked.
