mptcp_parse_option() currently sets OPTIONS_MPTCP_MPJ, for the three possible cases handled for MPTCPOPT_MP_JOIN option. OPTIONS_MPTCP_MPJ is the combination of three flags: - OPTION_MPTCP_MPJ_SYN - OPTION_MPTCP_MPJ_SYNACK - OPTION_MPTCP_MPJ_ACK This is a problem, because backup, join_id, token, nonce and/or hmac fields could be left uninitialized in some cases. Distinguish the three cases, as following patches will need this step. Fixes: f296234c ("mptcp: Add handling of incoming MP_JOIN requests") Signed-off-by:

The RZ/G3S SMARC Module has 2 KSZ9131 PHYs. In this setup, the KSZ9131 PHY is used with the ravb Ethernet driver. It has been discovered that when bringing the Ethernet interface down/up continuously, e.g., with the following sh script: $ while :; do ifconfig eth0 down; ifconfig eth0 up; done the link speed and duplex are wrong after interrupting the bring down/up operation even though the Ethernet interface is up. To recover from this state the following configuration sequence is necessary (executed manually): $ ifconfig eth0 down $ ifconfig eth0 up The behavior has been identified also on the Microchip SAMA7G5-EK board which runs the macb driver and uses the same PHY. The order of PHY-related operations in ravb_open() is as follows: ravb_open() -> ravb_phy_start() -> ravb_phy_init() -> of_phy_connect() -> phy_connect_direct() -> phy_attach_direct() -> phy_init_hw() -> phydev->drv->soft_reset() phydev->drv->config_init() phydev->drv->config_intr() phy_resume() kszphy_resume() The order of PHY-related operations in ravb_close is as follows: ravb_close() -> phy_stop() -> phy_suspend() -> kszphy_suspend() -> genphy_suspend() // set BMCR_PDOWN bit in MII_BMCR In genphy_suspend() setting the BMCR_PDWN bit in MII_BMCR switches the PHY to Software Power-Down (SPD) mode (according to the KSZ9131 datasheet). Thus, when opening the interface after it has been previously closed (via ravb_close()), the phydev->drv->config_init() and phydev->drv->config_intr() reach the KSZ9131 PHY driver via the ksz9131_config_init() and kszphy_config_intr() functions. KSZ9131 specifies that the MII management interface remains operational during SPD (Software Power-Down), but (according to manual): - Only access to the standard registers (0 through 31) is supported. - Access to MMD address spaces other than MMD address space 1 is possible if the spd_clock_gate_override bit is set. - Access to MMD address space 1 is not possible. The spd_clock_gate_override bit is not used in the KSZ9131 driver. ksz9131_config_init() configures RGMII delay, pad skews and LEDs by accessesing MMD registers other than those in address space 1. The datasheet for the KSZ9131 does not specify what happens if registers from an unsupported address space are accessed while the PHY is in SPD. To fix the issue the .soft_reset method has been instantiated for KSZ9131, too. This resets the PHY to the default state before doing any configurations to it, thus switching it out of SPD.

The HW has the capability to check each frame if it is a PTP frame, which domain it is, which ptp frame type it is, different ip address in the frame. And if one of these checks fail then the frame is not timestamp. Most of these checks were disabled except checking the field minorVersionPTP inside the PTP header. Meaning that once a partner sends a frame compliant to 8021AS which has minorVersionPTP set to 1, then the frame was not timestamp because the HW expected by default a value of 0 in minorVersionPTP. Fix this issue by removing this check so the userspace can decide on this. Fixes: cafc3662 ("net: micrel: Add PHC support for lan8841") Signed-off-by:

amt driver uses skb->cb for storing tunnel information. This job is worked before TC layer and then amt driver load tunnel info from skb->cb after TC layer. So, its cb area should not be overwrapped with CB area used by TC. In order to not use cb area used by TC, it skips the biggest cb structure used by TC, which was qdisc_skb_cb. But it's not anymore. Currently, biggest structure of TC's CB is tc_skb_cb. So, it should skip size of tc_skb_cb instead of qdisc_skb_cb.

Sanjuán García, Jorge says: ==================== net: ethernet: ti: am65-cpsw: Allow for MTU values The am65-cpsw-nuss driver has a fixed definition for the maximum ethernet frame length of 1522 bytes (AM65_CPSW_MAX_PACKET_SIZE). This limits the switch ports to only operate at a maximum MTU of 1500 bytes. When combining this CPSW switch with a DSA switch connected to one of its ports this limitation shows up. The extra 8 bytes the DSA subsystem adds internally to the ethernet frame create resulting frames bigger than 1522 bytes (1518 for non VLAN + 8 for DSA stuff) so they get dropped by the switch. One of the issues with the the am65-cpsw-nuss driver is that the network device max_mtu was being set to the same fixed value defined for the max total frame length (1522 bytes). This makes the DSA subsystem believe that the MTU of the interface can be set to 1508 bytes to make room for the extra 8 bytes of the DSA headers. However, all packages created assuming the 1500 bytes payload get dropped by the switch as oversized. This series offers a solution to this problem. The max_mtu advertised on the network device and the actual max frame size configured on the switch registers are made consistent by letting the extra room needed for the ethernet headers and the frame checksum (22 bytes including VLAN). ==================== Link: https://lore.kernel.org/r/20240105085530.14070-1-jorge.sanjuangarcia@duagon.comSigned-off-by:

The value of AM65_CPSW_MAX_PACKET_SIZE represents the maximum length of a received frame. This value is written to the register AM65_CPSW_PORT_REG_RX_MAXLEN. The maximum MTU configured on the network device should then leave some room for the ethernet headers and frame check. Otherwise, if the network interface is configured to its maximum mtu possible, the frames will be larger than AM65_CPSW_MAX_PACKET_SIZE and will get dropped as oversized. The switch supports ethernet frame sizes between 64 and 2024 bytes (including VLAN) as stated in the technical reference manual, so define AM65_CPSW_MAX_PACKET_SIZE with that maximum size.

rxrpc normally has the Don't Fragment flag set on the UDP packets it transmits, except when it has decided that DATA packets aren't getting through - in which case it turns it off just for the DATA transmissions. This can be a problem, however, for RESPONSE packets that convey authentication and crypto data from the client to the server as ticket may be larger than can fit in the MTU. In such a case, rxrpc gets itself into an infinite loop as the sendmsg returns an error (EMSGSIZE), which causes rxkad_send_response() to return -EAGAIN - and the CHALLENGE packet is put back on the Rx queue to retry, leading to the I/O thread endlessly attempting to perform the transmission. Fix this by disabling DF on RESPONSE packets for now. The use of DF and best data MTU determination needs reconsidering at some point in the future.

After the blamed commit, we started doing this dereference for every NETDEV_CHANGEUPPER and NETDEV_PRECHANGEUPPER event in the system. static inline struct dsa_port *dsa_user_to_port(const struct net_device *dev) { struct dsa_user_priv *p = netdev_priv(dev); return p->dp; } Which is obviously bogus, because not all net_devices have a netdev_priv() of type struct dsa_user_priv. But struct dsa_user_priv is fairly small, and p->dp means dereferencing 8 bytes starting with offset 16. Most drivers allocate that much private memory anyway, making our access not fault, and we discard the bogus data quickly afterwards, so this wasn't caught. But the dummy interface is somewhat special in that it calls alloc_netdev() with a priv size of 0. So every netdev_priv() dereference is invalid, and we get this when we emit a NETDEV_PRECHANGEUPPER event with a VLAN as its new upper: $ ip link add dummy1 type dummy $ ip link add link dummy1 name dummy1.100 type vlan id 100 [ 43.309174] ================================================================== [ 43.316456] BUG: KASAN: slab-out-of-bounds in dsa_user_prechangeupper+0x30/0xe8 [ 43.323835] Read of size 8 at addr ffff3f86481d2990 by task ip/374 [ 43.330058] [ 43.342436] Call trace: [ 43.366542] dsa_user_prechangeupper+0x30/0xe8 [ 43.371024] dsa_user_netdevice_event+0xb38/0xee8 [ 43.375768] notifier_call_chain+0xa4/0x210 [ 43.379985] raw_notifier_call_chain+0x24/0x38 [ 43.384464] __netdev_upper_dev_link+0x3ec/0x5d8 [ 43.389120] netdev_upper_dev_link+0x70/0xa8 [ 43.393424] register_vlan_dev+0x1bc/0x310 [ 43.397554] vlan_newlink+0x210/0x248 [ 43.401247] rtnl_newlink+0x9fc/0xe30 [ 43.404942] rtnetlink_rcv_msg+0x378/0x580 Avoid the kernel oops by dereferencing after the type check, as customary.

Pull networking updates from Paolo Abeni: "The most interesting thing is probably the networking structs reorganization and a significant amount of changes is around self-tests. Core & protocols: - Analyze and reorganize core networking structs (socks, netdev, netns, mibs) to optimize cacheline consumption and set up build time warnings to safeguard against future header changes This improves TCP performances with many concurrent connections up to 40% - Add page-pool netlink-based introspection, exposing the memory usage and recycling stats. This helps indentify bad PP users and possible leaks - Refine TCP/DCCP source port selection to no longer favor even source port at connect() time when IP_LOCAL_PORT_RANGE is set. This lowers the time taken by connect() for hosts having many active connections to the same destination - Refactor the TCP bind conflict code, shrinking related socket structs - Refactor TCP SYN-Cookie handling, as a preparation step to allow arbitrary SYN-Cookie processing via eBPF - Tune optmem_max for 0-copy usage, increasing the default value to 128KB and namespecifying it - Allow coalescing for cloned skbs coming from page pools, improving RX performances with some common configurations - Reduce extension header parsing overhead at GRO time - Add bridge MDB bulk deletion support, allowing user-space to request the deletion of matching entries - Reorder nftables struct members, to keep data accessed by the datapath first - Introduce TC block ports tracking and use. This allows supporting multicast-like behavior at the TC layer - Remove UAPI support for retired TC qdiscs (dsmark, CBQ and ATM) and classifiers (RSVP and tcindex) - More data-race annotations - Extend the diag interface to dump TCP bound-only sockets - Conditional notification of events for TC qdisc class and actions - Support for WPAN dynamic associations with nearby devices, to form a sub-network using a specific PAN ID - Implement SMCv2.1 virtual ISM device support - Add support for Batman-avd mulicast packet type BPF: - Tons of verifier improvements: - BPF register bounds logic and range support along with a large test suite - log improvements - complete precision tracking support for register spills - track aligned STACK_ZERO cases as imprecise spilled registers. This improves the verifier "instructions processed" metric from single digit to 50-60% for some programs - support for user's global BPF subprogram arguments with few commonly requested annotations for a better developer experience - support tracking of BPF_JNE which helps cases when the compiler transforms (unsigned) "a > 0" into "if a == 0 goto xxx" and the like - several fixes - Add initial TX metadata implementation for AF_XDP with support in mlx5 and stmmac drivers. Two types of offloads are supported right now, that is, TX timestamp and TX checksum offload - Fix kCFI bugs in BPF all forms of indirect calls from BPF into kernel and from kernel into BPF work with CFI enabled. This allows BPF to work with CONFIG_FINEIBT=y - Change BPF verifier logic to validate global subprograms lazily instead of unconditionally before the main program, so they can be guarded using BPF CO-RE techniques - Support uid/gid options when mounting bpffs - Add a new kfunc which acquires the associated cgroup of a task within a specific cgroup v1 hierarchy where the latter is identified by its id - Extend verifier to allow bpf_refcount_acquire() of a map value field obtained via direct load which is a use-case needed in sched_ext - Add BPF link_info support for uprobe multi link along with bpftool integration for the latter - Support for VLAN tag in XDP hints - Remove deprecated bpfilter kernel leftovers given the project is developed in user-space (https://github.com/facebook/bpfilter) Misc: - Support for parellel TC self-tests execution - Increase MPTCP self-tests coverage - Updated the bridge documentation, including several so-far undocumented features - Convert all the net self-tests to run in unique netns, to avoid random failures due to conflict and allow concurrent runs - Add TCP-AO self-tests - Add kunit tests for both cfg80211 and mac80211 - Autogenerate Netlink families documentation from YAML spec - Add yml-gen support for fixed headers and recursive nests, the tool can now generate user-space code for all genetlink families for which we have specs - A bunch of additional module descriptions fixes - Catch incorrect freeing of pages belonging to a page pool Driver API: - Rust abstractions for network PHY drivers; do not cover yet the full C API, but already allow implementing functional PHY drivers in rust - Introduce queue and NAPI support in the netdev Netlink interface, allowing complete access to the device <> NAPIs <> queues relationship - Introduce notifications filtering for devlink to allow control application scale to thousands of instances - Improve PHY validation, requesting rate matching information for each ethtool link mode supported by both the PHY and host - Add support for ethtool symmetric-xor RSS hash - ACPI based Wifi band RFI (WBRF) mitigation feature for the AMD platform - Expose pin fractional frequency offset value over new DPLL generic netlink attribute - Convert older drivers to platform remove callback returning void - Add support for PHY package MMD read/write New hardware / drivers: - Ethernet: - Octeon CN10K devices - Broadcom 5760X P7 - Qualcomm SM8550 SoC - Texas Instrument DP83TG720S PHY - Bluetooth: - IMC Networks Bluetooth radio Removed: - WiFi: - libertas 16-bit PCMCIA support - Atmel at76c50x drivers - HostAP ISA/PCMCIA style 802.11b driver - zd1201 802.11b USB dongles - Orinoco ISA/PCMCIA 802.11b driver - Aviator/Raytheon driver - Planet WL3501 driver - RNDIS USB 802.11b driver Driver updates: - Ethernet high-speed NICs: - Intel (100G, ice, idpf): - allow one by one port representors creation and removal - add temperature and clock information reporting - add get/set for ethtool's header split ringparam - add again FW logging - adds support switchdev hardware packet mirroring - iavf: implement symmetric-xor RSS hash - igc: add support for concurrent physical and free-running timers - i40e: increase the allowable descriptors - nVidia/Mellanox: - Preparation for Socket-Direct multi-dev netdev.

Pull s390 updates from Alexander Gordeev: - Add machine variable capacity information to /proc/sysinfo. - Limit the waste of page tables and always align vmalloc area size and base address on segment boundary. - Fix a memory leak when an attempt to register interruption sub class (ISC) for the adjunct-processor (AP) guest failed. - Reset response code AP_RESPONSE_INVALID_GISA to understandable by guest AP_RESPONSE_INVALID_ADDRESS in response to a failed interruption sub class (ISC) registration attempt. - Improve reaction to adjunct-processor (AP) AP_RESPONSE_OTHERWISE_CHANGED response code when enabling interrupts on behalf of a guest. - Fix incorrect sysfs 'status' attribute of adjunct-processor (AP) queue device bound to the vfio_ap device driver when the mediated device is attached to a guest, but the queue device is not passed through. - Rework struct ap_card to hold the whole adjunct-processor (AP) card hardware information. As result, all the ugly bit checks are replaced by simple evaluations of the required bit fields. - Improve handling of some weird scenarios between service element (SE) host and SE guest with adjunct-processor (AP) pass-through support. - Change local_ctl_set_bit() and local_ctl_clear_bit() so they return the previous value of the to be changed control register. This is useful if a bit is only changed temporarily and the previous content needs to be restored. - The kernel starts with machine checks disabled and is expected to enable it once trap_init() is called. However the implementation allows machine checks early. Consistently enable it in trap_init() only. - local_mcck_disable() and local_mcck_enable() assume that machine checks are always enabled. Instead implement and use local_mcck_save() and local_mcck_restore() to disable machine checks and restore the previous state. - Modification of floating point control (FPC) register of a traced process using ptrace interface may lead to corruption of the FPC register of the tracing process. Fix this. - kvm_arch_vcpu_ioctl_set_fpu() allows to set the floating point control (FPC) register in vCPU, but may lead to corruption of the FPC register of the host process. Fix this. - Use READ_ONCE() to read a vCPU floating point register value from the memory mapped area. This avoids that, depending on code generation, a different value is tested for validity than the one that is used. - Get rid of test_fp_ctl(), since it is quite subtle to use it correctly. Instead copy a new floating point control register value into its save area and test the validity of the new value when loading it. - Remove superfluous save_fpu_regs() call. - Remove s390 support for ARCH_WANTS_DYNAMIC_TASK_STRUCT. All machines provide the vector facility since many years and the need to make the task structure size dependent on the vector facility does not exist. - Remove the "novx" kernel command line option, as the vector code runs without any problems since many years. - Add the vector facility to the z13 architecture level set (ALS). All hypervisors support the vector facility since many years. This allows compile time optimizations of the kernel. - Get rid of MACHINE_HAS_VX and replace it with cpu_has_vx(). As result, the compiled code will have less runtime checks and less code. - Convert pgste_get_lock() and pgste_set_unlock() ASM inlines to C. - Convert the struct subchannel spinlock from pointer to member. * tag 's390-6.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (24 commits) Revert "s390: update defconfigs" s390/cio: make sch->lock spinlock pointer a member s390: update defconfigs s390/mm: convert pgste locking functions to C s390/fpu: get rid of MACHINE_HAS_VX s390/als: add vector facility to z13 architecture level set s390/fpu: remove "novx" option s390/fpu: remove ARCH_WANTS_DYNAMIC_TASK_STRUCT support KVM: s390: remove superfluous save_fpu_regs() call s390/fpu: get rid of test_fp_ctl() KVM: s390: use READ_ONCE() to read fpc register value KVM: s390: fix setting of fpc register s390/ptrace: handle setting of fpc register correctly s390/nmi: implement and use local_mcck_save() / local_mcck_restore() s390/nmi: consistently enable machine checks in trap_init() s390/ctlreg: return old register contents when changing bits s390/ap: handle outband SE bind state change s390/ap: store TAPQ hwinfo in struct ap_card s390/vfio-ap: fix sysfs status attribute for AP queue devices s390/vfio-ap: improve reaction to response code 07 from PQAP(AQIC) command ...

There are still some remaining warnings in minor platforms, but the series should catch most of the widely used ones make them more consistent with one another.

Pull sysctl updates from Luis Chamberlain: "To help make the move of sysctls out of kernel/sysctl.c not incur a size penalty sysctl has been changed to allow us to not require the sentinel, the final empty element on the sysctl array. Joel Granados has been doing all this work. In the v6.6 kernel we got the major infrastructure changes required to support this. For v6.7 we had all arch/ and drivers/ modified to remove the sentinel. For v6.8-rc1 we get a few more updates for fs/ directory only. The kernel/ directory is left but we'll save that for v6.9-rc1 as those patches are still being reviewed. After that we then can expect also the removal of the no longer needed check for procname == NULL. Let us recap the purpose of this work: - this helps reduce the overall build time size of the kernel and run time memory consumed by the kernel by about ~64 bytes per array - the extra 64-byte penalty is no longer inncurred now when we move sysctls out from kernel/sysctl.c to their own files Thomas Weißschuh also sent a few cleanups, for v6.9-rc1 we expect to see further work by Thomas Weißschuh with the constificatin of the struct ctl_table. Due to Joel Granados's work, and to help bring in new blood, I have suggested for him to become a maintainer and he's accepted. So for v6.9-rc1 I look forward to seeing him sent you a pull request for further sysctl changes.

This is prep work for the memory allocation profiling patchset which adds new sched.h interdepencencies" * tag 'header_cleanup-2024-01-10' of https://evilpiepirate.org/git/bcachefs: (51 commits) Kill sched.h dependency on rcupdate.h kill unnecessary thread_info.h include Kill unnecessary kernel.h include preempt.h: Kill dependency on list.h rseq: Split out rseq.h from sched.h LoongArch: signal.c: add header file to fix build error restart_block: Trim includes lockdep: move held_lock to lockdep_types.h sem: Split out sem_types.h uidgid: Split out uidgid_types.h seccomp: Split out seccomp_types.h refcount: Split out refcount_types.h uapi/linux/resource.h: fix include x86/signal: kill dependency on time.h syscall_user_dispatch.h: split out *_types.h mm_types_task.h: Trim dependencies Split out irqflags_types.h ipc: Kill bogus dependency on spinlock.h shm: Slim down dependencies workqueue: Split out workqueue_types.h ...

Pull bcachefs updates from Kent Overstreet: - btree write buffer rewrite: instead of adding keys to the btree write buffer at transaction commit time, we now journal them with a different journal entry type and copy them from the journal to the write buffer just prior to journal write. This reduces the number of atomic operations on shared cachelines in the transaction commit path and is a signicant performance improvement on some workloads: multithreaded 4k random writes went from ~650k iops to ~850k iops. - Bring back optimistic spinning for six locks: the new implementation doesn't use osq locks; instead we add to the lock waitlist as normal, and then spin on the lock_acquired bit in the waitlist entry, _not_ the lock itself. - New ioctls: - BCH_IOCTL_DEV_USAGE_V2, which allows for new data types - BCH_IOCTL_OFFLINE_FSCK, which runs the kernel implementation of fsck but without mounting: useful for transparently using the kernel version of fsck from 'bcachefs fsck' when the kernel version is a better match for the on disk filesystem. - BCH_IOCTL_ONLINE_FSCK: online fsck. Not all passes are supported yet, but the passes that are supported are fully featured - errors may be corrected as normal. The new ioctls use the new 'thread_with_file' abstraction for kicking off a kthread that's tied to a file descriptor returned to userspace via the ioctl. - btree_paths within a btree_trans are now dynamically growable, instead of being limited to 64. This is important for the check_directory_structure phase of fsck, and also fixes some issues we were having with btree path overflow in the reflink btree. - Trigger refactoring; prep work for the upcoming disk space accounting rewrite - Numerous bugfixes :) * tag 'bcachefs-2024-01-10' of https://evilpiepirate.org/git/bcachefs: (226 commits) bcachefs: eytzinger0_find() search should be const bcachefs: move "ptrs not changing" optimization to bch2_trigger_extent() bcachefs: fix simulateously upgrading & downgrading bcachefs: Restart recovery passes more reliably bcachefs: bch2_dump_bset() doesn't choke on u64s == 0 bcachefs: improve checksum error messages bcachefs: improve validate_bset_keys() bcachefs: print sb magic when relevant bcachefs: __bch2_sb_field_to_text() bcachefs: %pg is banished bcachefs: Improve would_deadlock trace event bcachefs: fsck_err()s don't need to manually check c->sb.version anymore bcachefs: Upgrades now specify errors to fix, like downgrades bcachefs: no thread_with_file in userspace bcachefs: Don't autofix errors we can't fix bcachefs: add missing bch2_latency_acct() call bcachefs: increase max_active on io_complete_wq bcachefs: add time_stats for btree_node_read_done() bcachefs: don't clear accessed bit in btree node fill bcachefs: Add an option to control btree node prefetching ... -
