syzbot reported uninit-value in tcp_recvmsg() [1] Issue here is that msg->msg_get_inq should have been cleared, otherwise tcp_recvmsg() might read garbage and perform more work than needed, or have undefined behavior. Given CONFIG_INIT_STACK_ALL_ZERO=y is probably going to be the default soon, I chose to change __sys_recvfrom() to clear all fields but msghdr.addr which might be not NULL. For __copy_msghdr_from_user(), I added an explicit clear of kmsg->msg_get_inq.

When a packet enters the OVS datapath and does not match any existing flows installed in the kernel flow cache, the packet will be sent to userspace to be parsed, and a new flow will be created. The kernel and OVS rely on each other to parse packet fields in the same way so that packets will be handled properly. As per the design document linked below, OVS expects all later IPv6 fragments to have nw_proto=44 in the flow key, so they can be correctly matched on OpenFlow rules. OpenFlow controllers create pipelines based on this design. This behavior was changed by the commit in the Fixes tag so that nw_proto equals the next_header field of the last extension header. However, there is no counterpart for this change in OVS userspace, meaning that this field is parsed differently between OVS and the kernel. This is a problem because OVS creates actions based on what is parsed in userspace, but the kernel-provided flow key is used as a match criteria, as described in Documentation/networking/openvswitch.rst. This leads to issues such as packets incorrectly matching on a flow and thus the wrong list of actions being applied to the packet. Such changes in packet parsing cannot be implemented without breaking the userspace. The offending commit is partially reverted to restore the expected behavior. The change technically made sense and there is a good reason that it was implemented, but it does not comply with the original design of OVS. If in the future someone wants to implement such a change, then it must be user-configurable and disabled by default to preserve backwards compatibility with existing OVS versions.

Commit 8a59f9d1 ("sock: Introduce sk->sk_prot->psock_update_sk_prot()") has moved the inet_csk_has_ulp(sk) check from sk_psock_init() to the new tcp_bpf_update_proto() function. I'm guessing that this was done to allow creating psocks for non-inet sockets. Unfortunately the destruction path for psock includes the ULP unwind, so we need to fail the sk_psock_init() itself. Otherwise if ULP is already present we'll notice that later, and call tcp_update_ulp() with the sk_proto of the ULP itself, which will most likely result in the ULP looping its callbacks.

The following sequence currently causes a driver bug warning when using virtio_net: # ip link set eth0 up # echo mem > /sys/power/state (or e.g. # rtcwake -s 10 -m mem) <resume> # ip link set eth0 down Missing register, driver bug WARNING: CPU: 0 PID: 375 at net/core/xdp.c:138 xdp_rxq_info_unreg+0x58/0x60 Call trace: xdp_rxq_info_unreg+0x58/0x60 virtnet_close+0x58/0xac __dev_close_many+0xac/0x140 __dev_change_flags+0xd8/0x210 dev_change_flags+0x24/0x64 do_setlink+0x230/0xdd0 ... This happens because virtnet_freeze() frees the receive_queue completely (including struct xdp_rxq_info) but does not call xdp_rxq_info_unreg(). Similarly, virtnet_restore() sets up the receive_queue again but does not call xdp_rxq_info_reg(). Actually, parts of virtnet_freeze_down() and virtnet_restore_up() are almost identical to virtnet_close() and virtnet_open(): only the calls to xdp_rxq_info_(un)reg() are missing. This means that we can fix this easily and avoid such problems in the future by just calling virtnet_close()/open() from the freeze/restore handlers. Aside from adding the missing xdp_rxq_info calls the only difference is that the refill work is only cancelled if netif_running(). However, this should not make any functional difference since the refill work should only be active if the network interface is actually up.

Intel I210 on some Intel Alder Lake platforms can only achieve ~750Mbps Tx speed via iperf. The RR2DCDELAY shows around 0x2xxx DMA delay, which will be significantly lower when 1) ASPM is disabled or 2) SoC package c-state stays above PC3. When the RR2DCDELAY is around 0x1xxx the Tx speed can reach to ~950Mbps. According to the I210 datasheet "8.26.1 PCIe Misc. Register - PCIEMISC", "DMA Idle Indication" doesn't seem to tie to DMA coalesce anymore, so set it to 1b for "DMA is considered idle when there is no Rx or Tx AND when there are no TLPs indicating that CPU is active detected on the PCIe link (such as the host executes CSR or Configuration register read or write operation)" and performing Tx should also fall under "active CPU on PCIe link" case. In addition to that, commit b6e0c419 ("igb: Move DMA Coalescing init code to separate function.") seems to wrongly changed from enabling E1000_PCIEMISC_LX_DECISION to disabling it, also fix that.

It was discovered that the Documentation lacks of a fundamental detail on how to correctly change the MAX_FRAME_SIZE of the switch. In fact if the MAX_FRAME_SIZE is changed while the cpu port is on, the switch panics and cease to send any packet. This cause the mgmt ethernet system to not receive any packet (the slow fallback still works) and makes the device not reachable. To recover from this a switch reset is required. To correctly handle this, turn off the cpu ports before changing the MAX_FRAME_SIZE and turn on again after the value is applied.

Under CONFIG_FORTIFY_SOURCE=y and CONFIG_UBSAN_BOUNDS=y, Clang is bugged here for calculating the size of the destination buffer (0x10 instead of 0x14). This copy is a fixed size (sizeof(struct fw_section_info_st)), with the source and dest being struct fw_section_info_st, so the memcpy should be safe, assuming the index is within bounds, which is UBSAN_BOUNDS's responsibility to figure out. Avoid the whole thing and just do a direct assignment. This results in no change to the executable code.

Simon reports that if two LAN9514 USB adapters are directly connected without an intermediate switch, the link fails to come up and link LEDs remain dark. The issue was introduced by commit 1ce8b372 ("usbnet: smsc95xx: Forward PHY interrupts to PHY driver to avoid polling"). The PHY suffers from a known erratum wherein link detection becomes unreliable if Energy Detect Power-Down is used. In poll mode, the driver works around the erratum by briefly disabling EDPD for 640 msec to detect a neighbor, then re-enabling it to save power. In interrupt mode, no interrupt is signaled if EDPD is used by both link partners, so it must not be enabled at all. We'll recoup the power savings by enabling SUSPEND1 mode on affected LAN95xx chips in a forthcoming commit.

Do not allow setting less channels, than Traffic Classes there are via ethtool. There must be at least one channel per Traffic Class. If you set less channels, than Traffic Classes there are, then during ice_vsi_rebuild there would be allocated only the requested amount of tx/rx rings in ice_vsi_alloc_arrays. But later in ice_vsi_setup_q_map there would be requested at least one channel per Traffic Class. This results in setting num_rxq > alloc_rxq and num_txq > alloc_txq. Later, there would be a NULL pointer dereference in ice_vsi_map_rings_to_vectors, because we go beyond of rx_rings or tx_rings arrays. Change ice_set_channels() to return error if you try to allocate less channels, than Traffic Classes there are. Change ice_vsi_setup_q_map() and ice_vsi_setup_q_map_mqprio() to return status code instead of void.

In current implementation ice_update_phy_type enables all link modes for selected speed. This approach doesn't work for 1000M speeds, because both copper (1000baseT) and optical (1000baseX) standards cannot be enabled at once. Fix this, by adding the function `ice_set_phy_type_from_speed()` for 1000M speeds. Fixes: 48cb27f2 ("ice: Implement handlers for ethtool PHY/link operations") Signed-off-by:

Commit 34a89775 ("ice: Add support for inner etype in switchdev") added the ability to match on inner ethertype. A side effect of that change is that it is now impossible to add some filters for protocols which do not contain inner ethtype field. tc requires the protocol field to be specified when providing certain other options, e.g. src_ip. This is a problem in case of GTP - when user wants to specify e.g. src_ip, they also need to specify protocol in tc command (otherwise tc fails with: Illegal "src_ip"). Because GTP is a tunnel, the protocol field is treated as inner protocol. GTP does not contain inner ethtype field and the filter cannot be added. To fix this, ignore the ethertype field in case of GTP filters. Fixes: 9a225f81 ("ice: Support GTP-U and GTP-C offload in switchdev") Signed-off-by:

Pull signature checking selftest from David Howells: "The signature checking code, as used by module signing, kexec, etc., is non-FIPS compliant as there is no selftest. For a kernel to be FIPS-compliant, signature checking would have to be tested before being used, and the box would need to panic if it's not available (probably reasonable as simply disabling signature checking would prevent you from loading any driver modules). Deal with this by adding a minimal test. This is split into two patches: the first moves load_certificate_list() to the same place as the X.509 code to make it more accessible internally; the second adds a selftest" * tag 'certs-20220621' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: certs: Add FIPS selftests certs: Move load_certificate_list() to be with the asymmetric keys code

The recent patch to make afs_getattr consult the server didn't account for the pseudo-inodes employed by the dynamic root-type afs superblock not having a volume or a server to access, and thus an oops occurs if such a directory is stat'd. Fix this by checking to see if the vnode->volume pointer actually points anywhere before following it in afs_getattr(). This can be tested by stat'ing a directory in /afs. It may be sufficient just to do "ls /afs" and the oops looks something like: BUG: kernel NULL pointer dereference, address: 0000000000000020 ... RIP: 0010:afs_getattr+0x8b/0x14b ...

Add some selftests for signature checking when FIPS mode is enabled. These need to be done before we start actually using the signature checking for things and must panic the kernel upon failure. Note that the tests must not check the blacklist lest this provide a way to prevent a kernel from booting by installing a hash of a test key in the appropriate UEFI table. Reported-by:

It's been reported that the recent fix for skipping the component-binding with D-GPU caused a regression on some systems; it resulted in the completely missing component binding with i915 GPU. The problem was the use of pci_get_class() function. It matches with the full PCI class bits, while we want to match only partially the PCI base class bits. So, when a system has an i915 graphics device with the PCI class 0380, it won't hit because we're looking for only the PCI class 0300. This patch fixes i915_gfx_present() to look up each PCI device and match with PCI base class explicitly instead of pci_get_class().

Eric reports skb_under_panic when using dup/fwd via bond+egress hook. Before pushing mac header, we should make sure that we're called from ingress to put back what was pulled earlier. In egress case, the MAC header is already there; we should leave skb alone. While at it be more careful here: skb might have been altered and headroom reduced, so add a skb_cow() before so that headroom is increased if necessary. nf_do_netdev_egress() assumes skb ownership (it normally ends with a call to dev_queue_xmit), so we must free the packet on error.
