On mt753x_cpu_port_enable() there's code that enables flooding for the CPU port only. Since mt753x_cpu_port_enable() runs twice when both CPU ports are enabled, port 6 becomes the only port to forward the frames to. But port 5 is the active port, so no frames received from the user ports will be forwarded to port 5 which breaks network connectivity. Every bit of the BC_FFP, UNM_FFP, and UNU_FFP bits represents a port. Fix this issue by setting the bit that corresponds to the CPU port without overwriting the other bits. Clear the bits beforehand only for the MT7531 switch. According to the documents MT7621 Giga Switch Programming Guide v0.3 and MT7531 Reference Manual for Development Board v1.0, after reset, the BC_FFP, UNM_FFP, and UNU_FFP bits are set to 1 for MT7531, 0 for MT7530. The commit 5e5502e0 ("net: dsa: mt7530: fix roaming from DSA user ports") silently changed the method to set the bits on the MT7530_MFC. Instead of clearing the relevant bits before mt7530_cpu_port_enable() which runs under a for loop, the commit started doing it on mt7530_cpu_port_enable(). Back then, this didn't really matter as only a single CPU port could be used since the CPU port number was hardcoded. The driver was later changed with commit 1f9a6abe ("net: dsa: mt7530: get cpu-port via dp->cpu_dp instead of constant") to retrieve the CPU port via dp->cpu_dp. With that, this silent change became an issue for when using multiple CPU ports. Fixes: 5e5502e0 ("net: dsa: mt7530: fix roaming from DSA user ports") Signed-off-by:

The multi-chip module MT7530 switch with a 40 MHz oscillator on the MT7621AT, MT7621DAT, and MT7621ST SoCs forwards corrupt frames using trgmii. This is caused by the assumption that MT7621 SoCs have got 150 MHz PLL, hence using the ncpo1 value, 0x0780. My testing shows this value works on Unielec U7621-06, Bartel's testing shows it won't work on Hi-Link HLK-MT7621A and Netgear WAC104. All devices tested have got 40 MHz oscillators. Using the value for 125 MHz PLL, 0x0640, works on all boards at hand. The definitions for 125 MHz PLL exist on the Banana Pi BPI-R2 BSP source code whilst 150 MHz PLL don't. Forwarding frames using trgmii on the MCM MT7530 switch with a 25 MHz oscillator on the said MT7621 SoCs works fine because the ncpo1 value defined for it is for 125 MHz PLL. Change the 150 MHz PLL comment to 125 MHz PLL, and use the 125 MHz PLL ncpo1 values for both oscillator frequencies.

syzkaller reported a warning below [0]. We can reproduce it by sending 0-byte data from the (AF_PACKET, SOCK_PACKET) socket via some devices whose dev->hard_header_len is 0. struct sockaddr_pkt addr = { .spkt_family = AF_PACKET, .spkt_device = "tun0", }; int fd; fd = socket(AF_PACKET, SOCK_PACKET, 0); sendto(fd, NULL, 0, 0, (struct sockaddr *)&addr, sizeof(addr)); We have a similar fix for the (AF_PACKET, SOCK_RAW) socket as commit dc633700 ("net/af_packet: check len when min_header_len equals to 0"). Let's add the same test for the SOCK_PACKET socket.

igc_configure_rx_ring() function will be called as part of XDP program setup. If Rx hardware timestamp is enabled prio to XDP program setup, this timestamp enablement will be overwritten when buffer size is written into SRRCTL register. Thus, this commit read the register value before write to SRRCTL register. This commit is tested by using xdp_hw_metadata bpf selftest tool. The tool enables Rx hardware timestamp and then attach XDP program to igc driver. It will display hardware timestamp of UDP packet with port number 9092. Below are detail of test steps and results. Command on DUT: sudo ./xdp_hw_metadata <interface name> Command on Link Partner: echo -n skb | nc -u -q1 <destination IPv4 addr> 9092 Result before this patch: skb hwtstamp is not found!

It is not possible to set the number of lanes when setting link modes using the legacy IOCTL ethtool interface. Since 'struct ethtool_link_ksettings' is not initialized in this path, drivers receive an uninitialized number of lanes in 'struct ethtool_link_ksettings::lanes'. When this information is later queried from drivers, it results in the ethtool code making decisions based on uninitialized memory, leading to the following KMSAN splat [1]. In practice, this most likely only happens with the tun driver that simply returns whatever it got in the set operation. As far as I can tell, this uninitialized memory is not leaked to user space thanks to the 'ethtool_ops->cap_link_lanes_supported' check in linkmodes_prepare_data(). Fix by initializing the structure in the IOCTL path. Did not find any more call sites that pass an uninitialized structure when calling 'ethtool_ops::set_link_ksettings()'.

Upon physical link change, firmware reports to the kernel about the change along with the details like speed, lmac_type_id, etc. Kernel derives lmac_type based on lmac_type_id received from firmware. In a few scenarios, firmware returns an invalid lmac_type_id, which is resulting in below kernel panic. This patch adds the missing validation of the lmac_type_id field.

APR table contains the lmtst base address of PF/VFs. These entries are updated by the PF/VF during the device probe. The lmtst address is fetched from HW using "TXN_REQ" and "ADDR_RSP_STS" registers. The lock tries to protect these registers from getting overwritten when multiple PFs invokes rvu_get_lmtaddr() simultaneously. For example, if PF1 submit the request and got permitted before it reads the response and PF2 got scheduled submit the request then the response of PF1 is overwritten by the PF2 response.

Through testing I found out that hardware vlan rx offload support seems to have some hardware issues. At least when using multiple MACs and when receiving tagged packets on the secondary MAC, the hardware can sometimes start to emit wrong tags on the first MAC as well. In order to avoid such issues, drop the feature configuration and use the offload feature only for DSA hardware untagging on MT7621/MT7622 devices where this feature works properly.

David Howells says: ==================== rxrpc: Timeout handling fixes Here are three patches to fix timeouts handling in AF_RXRPC: (1) The hard call timeout should be interpreted in seconds, not milliseconds. (2) Allow a waiting call to be aborted (thereby cancelling the call) in the case a signal interrupts sendmsg() and leaves it hanging until it is granted a channel on a connection. (3) Kernel-generated calls get the timer started on them even if they're still waiting to be attached to a connection. If the timer expires before the wait is complete and a conn is attached, an oops will occur. ==================== Signed-off-by: -

afs_make_call() calls rxrpc_kernel_begin_call() to begin a call (which may get stalled in the background waiting for a connection to become available); it then calls rxrpc_kernel_set_max_life() to set the timeouts - but that starts the call timer so the call timer might then expire before we get a connection assigned - leading to the following oops if the call stalled: BUG: kernel NULL pointer dereference, address: 0000000000000000 ...

The timer will be started when the first packet is transmitted. It shouldn't be possible to trigger this directly from userspace through AF_RXRPC as sendmsg() will return EBUSY if the call is in the waiting-for-conn state if it dropped out of the wait due to a signal.

When sendmsg() creates an rxrpc call, it queues it to wait for a connection and channel to be assigned and then waits before it can start shovelling data as the encrypted DATA packet content includes a summary of the connection parameters. However, sendmsg() may get interrupted before a connection gets assigned and further sendmsg() calls will fail with EBUSY until an assignment is made. Fix this so that the call can at least be aborted without failing on EBUSY. We have to be careful here as sendmsg() mustn't be allowed to start the call timer if the call doesn't yet have a connection assigned as an oops may follow shortly thereafter.
