2024-06-13bnxt_en: Cap the size of HWRM_PORT_PHY_QCFG forwarded responseMichael Chan2-2/+61
Firmware interface 1.10.2.118 has increased the size of HWRM_PORT_PHY_QCFG response beyond the maximum size that can be forwarded. When the VF's link state is not the default auto state, the PF will need to forward the response back to the VF to indicate the forced state. This regression may cause the VF to fail to initialize. Fix it by capping the HWRM_PORT_PHY_QCFG response to the maximum 96 bytes. The SPEEDS2_SUPPORTED flag needs to be cleared because the new speeds2 fields are beyond the legacy structure. Also modify bnxt_hwrm_fwd_resp() to print a warning if the message size exceeds 96 bytes to make this failure more obvious.

gve_rx_free_skb incorrectly leaves napi->skb referencing an skb after it is freed with dev_kfree_skb_any(). This can result in a subsequent call to napi_get_frags returning a dangling pointer. Fix this by clearing napi->skb before the skb is freed.

2024-06-13ionic: fix use after netif_napi_del()Taehee Yoo1-3/+1
When queues are started, netif_napi_add() and napi_enable() are called. If there are 4 queues and only 3 queues are used for the current configuration, only 3 queues' napi should be registered and enabled. The ionic_qcq_enable() checks whether the .poll pointer is not NULL for enabling only the using queue' napi. Unused queues' napi will not be registered by netif_napi_add(), so the .poll pointer indicates NULL. But it couldn't distinguish whether the napi was unregistered or not because netif_napi_del() doesn't reset the .poll pointer to NULL. So, ionic_qcq_enable() calls napi_enable() for the queue, which was unregistered by netif_napi_del().

parameters The current cbs parameter depends on speed after uplinking, which is not needed and will report a configuration error if the port is not initially connected. The UAPI exposed by tc-cbs requires userspace to recalculate the send slope anyway, because the formula depends on port_transmit_rate (see man tc-cbs), which is not an invariant from tc's perspective. Therefore, we use offload->sendslope and offload->idleslope to derive the original port_transmit_rate from the CBS formula.

2024-06-11gve: ignore nonrelevant GSO type bits when processing TSO headersJoshua Washington1-15/+5
TSO currently fails when the skb's gso_type field has more than one bit set. TSO packets can be passed from userspace using PF_PACKET, TUNTAP and a few others, using virtio_net_hdr (e.g., PACKET_VNET_HDR). This includes virtualization, such as QEMU, a real use-case. The gso_type and gso_size fields as passed from userspace in virtio_net_hdr are not trusted blindly by the kernel. It adds gso_type |= SKB_GSO_DODGY to force the packet to enter the software GSO stack for verification. This issue might similarly come up when the CWR bit is set in the TCP header for congestion control, causing the SKB_GSO_TCP_ECN gso_type bit to be set.

Commit 070246e4674b ("net: stmmac: Fix for mismatched host/device DMA address width") added support in the stmmac driver for platform drivers to indicate the host DMA width, but left it up to authors of the specific platforms to indicate if their width differed from the addr64 register read from the MAC itself. Qualcomm's EMAC4 integration supports only up to 36 bit width (as opposed to the addr64 register indicating 40 bit width). Let's indicate that in the platform driver to avoid a scenario where the driver will allocate descriptors of size that is supported by the CPU which in our case is 36 bit, but as the addr64 register is still capable of 40 bits the device will use two descriptors as one address.

2024-06-07liquidio: Adjust a NULL pointer handling path in lio_vf_rep_copy_packetAleksandr Mishin1-6/+5
In lio_vf_rep_copy_packet() pg_info->page is compared to a NULL value, but then it is unconditionally passed to skb_add_rx_frag() which looks strange and could lead to null pointer dereference. lio_vf_rep_copy_packet() call trace looks like: octeon_droq_process_packets octeon_droq_fast_process_packets octeon_droq_dispatch_pkt octeon_create_recv_info ...search in the dispatch_list... ->disp_fn(rdisp->rinfo, ...) lio_vf_rep_pkt_recv(struct octeon_recv_info *recv_info, ...) In this path there is no code which sets pg_info->page to NULL. So this check looks unneeded and doesn't solve potential problem. But I guess the author had reason to add a check and I have no such card and can't do real test. In addition, the code in the function liquidio_push_packet() in liquidio/lio_core.c does exactly the same. Based on this, I consider the most acceptable compromise solution to adjust this issue by moving skb_add_rx_frag() into conditional scope.

Also, dependency on the PF state reset flags creates an additional, fortunately less common problem: * PFR is requested e.g. by tx_timeout handler * .ndo_bpf() is asked to delete the program, calls ice_destroy_xdp_rings(), but reset flag is set, so rings are destroyed without deleting the program * ice_vsi_rebuild tries to delete non-existent XDP rings, because the program is still on the VSI * system crashes With a similar race, when requested to attach a program, ice_prepare_xdp_rings() can actually skip setting the program in the VSI and nevertheless report success. Instead of reverting to the old order of function calls, add an enum argument to both ice_prepare_xdp_rings() and ice_destroy_xdp_rings() in order to distinguish between calls from rebuild and .ndo_bpf().

2024-06-05ice: remove af_xdp_zc_qps bitmapLarysa Zaremba3-26/+27
Referenced commit has introduced a bitmap to distinguish between ZC and copy-mode AF_XDP queues, because xsk_get_pool_from_qid() does not do this for us. The bitmap would be especially useful when restoring previous state after rebuild, if only it was not reallocated in the process. This leads to e.g. xdpsock dying after changing number of queues. Instead of preserving the bitmap during the rebuild, remove it completely and distinguish between ZC and copy-mode queues based on the presence of a device associated with the pool.

2024-06-05ice: fix reads from NVM Shadow RAM on E830 and E825-C devicesJacob Keller2-9/+93
The ice driver reads data from the Shadow RAM portion of the NVM during initialization, including data used to identify the NVM image and device, such as the ETRACK ID used to populate devlink dev info fw.bundle. Currently it is using a fixed offset defined by ICE_CSS_HEADER_LENGTH to compute the appropriate offset. This worked fine for E810 and E822 devices which both have CSS header length of 330 words. Other devices, including both E825-C and E830 devices have different sizes for their CSS header. The use of a hard coded value results in the driver reading from the wrong block in the NVM when attempting to access the Shadow RAM copy. This results in the driver reporting the fw.bundle as 0x0 in both the devlink dev info and ethtool -i output. The first E830 support was introduced by commit ba20ecb1d1bb ("ice: Hook up 4 E830 devices by adding their IDs") and the first E825-C support was introducted by commit f64e18944233 ("ice: introduce new E825C devices family") The NVM actually contains the CSS header length embedded in it. Remove the hard coded value and replace it with logic to read the length from the NVM directly. This is more resilient against all existing and future hardware, vs looking up the expected values from a table. It ensures the driver will read from the appropriate place when determining the ETRACK ID value used for populating the fw.bundle_id and for reporting in ethtool -i. The CSS header length for both the active and inactive flash bank is stored in the ice_bank_info structure to avoid unnecessary duplicate work when accessing multiple words of the Shadow RAM. Both banks are read in the unlikely event that the header length is different for the NVM in the inactive bank, rather than being different only by the overall device family.

2024-06-05ice: fix iteration of TLVs in Preserved Fields AreaJacob Keller1-7/+21
The ice_get_pfa_module_tlv() function iterates over the Type-Length-Value structures in the Preserved Fields Area (PFA) of the NVM. This is used by the driver to access data such as the Part Board Assembly identifier. The function uses simple logic to iterate over the PFA. First, the pointer to the PFA in the NVM is read. Then the total length of the PFA is read from the first word. A pointer to the first TLV is initialized, and a simple loop iterates over each TLV. The pointer is moved forward through the NVM until it exceeds the PFA area. The logic seems sound, but it is missing a key detail. The Preserved Fields Area length includes one additional final word. This is documented in the device data sheet as a dummy word which contains 0xFFFF. All NVMs have this extra word. If the driver tries to scan for a TLV that is not in the PFA, it will read past the size of the PFA. It reads and interprets the last dummy word of the PFA as a TLV with type 0xFFFF. It then reads the word following the PFA as a length. The PFA resides within the Shadow RAM portion of the NVM, which is relatively small. All of its offsets are within a 16-bit size. The PFA pointer and TLV pointer are stored by the driver as 16-bit values. In almost all cases, the word following the PFA will be such that interpreting it as a length will result in 16-bit arithmetic overflow. Once overflowed, the new next_tlv value is now below the maximum offset of the PFA. Thus, the driver will continue to iterate the data as TLVs. In the worst case, the driver hits on a sequence of reads which loop back to reading the same offsets in an endless loop. To fix this, we need to correct the loop iteration check to account for this extra word at the end of the PFA. This alone is sufficient to resolve the known cases of this issue in the field. However, it is plausible that an NVM could be misconfigured or have corrupt data which results in the same kind of overflow. Protect against this by using check_add_overflow when calculating both the maximum offset of the TLVs, and when calculating the next_tlv offset at the end of each loop iteration. This ensures that the driver will not get stuck in an infinite loop when scanning the PFA.

2024-06-05net: ethernet: mtk_eth_soc: handle dma buffer size soc specificFrank Wunderlich2-36/+77
The mainline MTK ethernet driver suffers long time from rarly but annoying tx queue timeouts. We think that this is caused by fixed dma sizes hardcoded for all SoCs. We suspect this problem arises from a low level of free TX DMADs, the TX Ring alomost full. The transmit timeout is caused by the Tx queue not waking up. The Tx queue stops when the free counter is less than ring->thres, and it will wake up once the free counter is greater than ring->thres. If the CPU is too late to wake up the Tx queues, it may cause a transmit timeout. Therefore, we increased the TX and RX DMADs to improve this error situation. Use the dma-size implementation from SDK in a per SoC manner. In difference to SDK we have no RSS feature yet, so all RX/TX sizes should be raised from 512 to 2048 byte except fqdma on mt7988 to avoid the tx timeout issue.

2024-06-05vxlan: Fix regression when dropping packets due to invalid src addressesDaniel Borkmann1-4/+4
Commit f58f45c1e5b9 ("vxlan: drop packets from invalid src-address") has recently been added to vxlan mainly in the context of source address snooping/learning so that when it is enabled, an entry in the FDB is not being created for an invalid address for the corresponding tunnel endpoint. Before commit f58f45c1e5b9 vxlan was similarly behaving as geneve in that it passed through whichever macs were set in the L2 header. It turns out that this change in behavior breaks setups, for example, Cilium with netkit in L3 mode for Pods as well as tunnel mode has been passing before the change in f58f45c1e5b9 for both vxlan and geneve. After mentioned change it is only passing for geneve as in case of vxlan packets are dropped due to vxlan_set_mac() returning false as source and destination macs are zero which for E/W traffic via tunnel is totally fine. Fix it by only opting into the is_valid_ether_addr() check in vxlan_set_mac() when in fact source address snooping/learning is actually enabled in vxlan. This is done by moving the check into vxlan_snoop(). With this change, the Cilium connectivity test suite passes again for both tunnel flavors.

2024-06-05ionic: fix kernel panic in XDP_TX actionTaehee Yoo1-0/+1
In the XDP_TX path, ionic driver sends a packet to the TX path with rx page and corresponding dma address. After tx is done, ionic_tx_clean() frees that page. But RX ring buffer isn't reset to NULL. So, it uses a freed page, which causes kernel panic.

KSZ8061 needs to write to a MMD register at driver initialization to fix an errata. This worked in 5.0 kernel but not in newer kernels. The issue is the main phylib code no longer resets PHY at the very beginning. Calling phy resuming code later will reset the chip if it is already powered down at the beginning. This wipes out the MMD register write. Solution is to implement a phy resume function for KSZ8061 to take care of this problem.

2024-06-05efi: Add missing __nocfi annotations to runtime wrappersArd Biesheuvel1-7/+6
The EFI runtime wrappers are a sandbox for calling into EFI runtime services, which are invoked using indirect calls. When running with kCFI enabled, the compiler will require the target of any indirect call to be type annotated. Given that the EFI runtime services prototypes and calling convention are governed by the EFI spec, not the Linux kernel, adding such type annotations for firmware routines is infeasible, and so the compiler must be informed that prototype validation should be omitted. Add the __nocfi annotation at the appropriate places in the EFI runtime wrapper code to achieve this. Note that this currently only affects 32-bit ARM, given that other architectures that support both kCFI and EFI use an asm wrapper to call EFI runtime services, and this hides the indirect call from the compiler.

When vmxnet3_rq_create() fails to allocate memory for rq->data_ring.base, the subsequent call to vmxnet3_rq_destroy_all_rxdataring does not reset rq->data_ring.desc_size for the data ring that failed, which presumably causes the hypervisor to reference it on packet reception. To fix this bug, rq->data_ring.desc_size needs to be set to 0 to tell the hypervisor to disable this feature. [ 95.436876] kernel BUG at net/core/skbuff.c:207!

However kernel should not make any assumption on firmware's DMW setting, thus the entry point should be a physical address falls into direct translation region.
