2025-06-04wifi: iwlwifi: mld: Move regulatory domain initializationIlan Peer
The regulatory domain information was initialized every time the FW was loaded and the device was restarted. This was unnecessary and useless as at this stage the wiphy channels information was not setup yet so while the regulatory domain was set to the wiphy, the channel information was not updated. In case that a specific MCC was configured during FW initialization then following updates with this MCC are ignored, and thus the wiphy channels information is left with information not matching the regulatory domain. This commit moves the regulatory domain initialization to after the operational firmware is started, i.e., after the wiphy channels were configured and the regulatory information is needed.

2025-06-04wifi: iwlwifi: mld: avoid panic on init failureMiri Korenblit
In case of an error during init, in_hw_restart will be set, but it will never get cleared. Instead, we will retry to init again, and then we will act like we are in a restart when we are actually not. This causes (among others) to a NULL pointer dereference when canceling rx_omi::finished_work, that was not even initialized, because we thought that we are in hw_restart. Set in_hw_restart to true only if the fw is running, then we know that FW was loaded successfully and we are not going to the retry loop.

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Paolo Abeni: "Core: - Implement the Device Memory TCP transmit path, allowing zero-copy data transmission on top of TCP from e.g. GPU memory to the wire. - Move all the IPv6 routing tables management outside the RTNL scope, under its own lock and RCU. The route control path is now 3x times faster. - Convert queue related netlink ops to instance lock, reducing again the scope of the RTNL lock. This improves the control plane scalability. - Refactor the software crc32c implementation, removing unneeded abstraction layers and improving significantly the related micro-benchmarks. - Optimize the GRO engine for UDP-tunneled traffic, for a 10% performance improvement in related stream tests. - Cover more per-CPU storage with local nested BH locking; this is a prep work to remove the current per-CPU lock in local_bh_disable() on PREMPT_RT. - Introduce and use nlmsg_payload helper, combining buffer bounds verification with accessing payload carried by netlink messages. Netfilter: - Rewrite the procfs conntrack table implementation, improving considerably the dump performance. A lot of user-space tools still use this interface. - Implement support for wildcard netdevice in netdev basechain and flowtables. - Integrate conntrack information into nft trace infrastructure. - Export set count and backend name to userspace, for better introspection. BPF: - BPF qdisc support: BPF-qdisc can be implemented with BPF struct_ops programs and can be controlled in similar way to traditional qdiscs using the "tc qdisc" command. - Refactor the UDP socket iterator, addressing long standing issues WRT duplicate hits or missed sockets. Protocols: - Improve TCP receive buffer auto-tuning and increase the default upper bound for the receive buffer; overall this improves the single flow maximum thoughput on 200Gbs link by over 60%. - Add AFS GSSAPI security class to AF_RXRPC; it provides transport security for connections to the AFS fileserver and VL server. - Improve TCP multipath routing, so that the sources address always matches the nexthop device. - Introduce SO_PASSRIGHTS for AF_UNIX, to allow disabling SCM_RIGHTS, and thus preventing DoS caused by passing around problematic FDs. - Retire DCCP socket. DCCP only receives updates for bugs, and major distros disable it by default. Its removal allows for better organisation of TCP fields to reduce the number of cache lines hit in the fast path. - Extend TCP drop-reason support to cover PAWS checks. Driver API: - Reorganize PTP ioctl flag support to require an explicit opt-in for the drivers, avoiding the problem of drivers not rejecting new unsupported flags. - Converted several device drivers to timestamping APIs. - Introduce per-PHY ethtool dump helpers, improving the support for dump operations targeting PHYs. Tests and tooling: - Add support for classic netlink in user space C codegen, so that ynl-c can now read, create and modify links, routes addresses and qdisc layer configuration. - Add ynl sub-types for binary attributes, allowing ynl-c to output known struct instead of raw binary data, clarifying the classic netlink output. - Extend MPTCP selftests to improve the code-coverage. - Add tests for XDP tail adjustment in AF_XDP. New hardware / drivers: - OpenVPN virtual driver: offload OpenVPN data channels processing to the kernel-space, increasing the data transfer throughput WRT the user-space implementation. - Renesas glue driver for the gigabit ethernet RZ/V2H(P) SoC. - Broadcom asp-v3.0 ethernet driver. - AMD Renoir ethernet device. - ReakTek MT9888 2.5G ethernet PHY driver. - Aeonsemi 10G C45 PHYs driver.

Pull nfsd updates from Chuck Lever: "The marquee feature for this release is that the limit on the maximum rsize and wsize has been raised to 4MB. The default remains at 1MB, but risk-seeking administrators now have the ability to try larger I/O sizes with NFS clients that support them. Eventually the default setting will be increased when we have confidence that this change will not have negative impact. With v6.16, NFSD now has its own debugfs file system where we can add experimental features and make them available outside of our development community without impacting production deployments. The first experimental setting added is one that makes all NFS READ operations use vfs_iter_read() instead of the NFSD splice actor. The plan is to eventually retire the splice actor, as that will enable a number of new capabilities such as the use of struct bio_vec from the top to the bottom of the NFSD stack. Jeff Layton contributed a number of observability improvements. The use of dprintk() in a number of high-traffic code paths has been replaced with static trace points. This release sees the continuation of efforts to harden the NFSv4.2 COPY operation. Soon, the restriction on async COPY operations can be lifted.

git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux Pull selinux updates from Paul Moore: - Reduce the SELinux impact on path walks. Add a small directory access cache to the per-task SELinux state. This cache allows SELinux to cache the most recently used directory access decisions in order to avoid repeatedly querying the AVC on path walks where the majority of the directories have similar security contexts/labels. My performance measurements are crude, but prior to this patch the time spent in SELinux code on a 'make allmodconfig' run was 103% that of __d_lookup_rcu(), and with this patch the time spent in SELinux code dropped to 63% of __d_lookup_rcu(), a ~40% improvement. Additional improvments can be expected in the future, but those will require additional SELinux policy/toolchain support. - Add support for wildcards in genfscon policy statements. This patch allows for wildcards in the genfscon patch matching logic as opposed to the prefix matching that was used prior to this change. Adding wilcard support allows for more expressive and efficient path matching in the policy which is especially helpful for sysfs, and has resulted in a ~15% boot time reduction in Android. SELinux policies can opt into wilcard matching by using the "genfs_seclabel_wildcard" policy capability. - Unify the error/OOM handling of the SELinux network caches. A failure to allocate memory for the SELinux network caches isn't fatal as the object label can still be safely returned to the caller, it simply means that we cannot add the new data to the cache, at least temporarily. This patch corrects this behavior for the InfiniBand cache and does some minor cleanup. - Minor improvements around constification, 'likely' annotations, and removal of bogus comments. * tag 'selinux-pr-20250527' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux: selinux: fix the kdoc header for task_avdcache_update selinux: remove a duplicated include selinux: reduce path walk overhead selinux: support wildcard match in genfscon selinux: drop copy-paste comment selinux: unify OOM handling in network hashtables selinux: add likely hints for fast paths selinux: contify network namespace pointer selinux: constify network address pointer

2025-05-28net: phy: mscc: Stop clearing the the UDPv4 checksum for L2 framesHoratiu Vultur
We have noticed that when PHY timestamping is enabled, L2 frames seems to be modified by changing two 2 bytes with a value of 0. The place were these 2 bytes seems to be random(or I couldn't find a pattern). In most of the cases the userspace can ignore these frames but if for example those 2 bytes are in the correction field there is nothing to do. This seems to happen when configuring the HW for IPv4 even that the flow is not enabled. These 2 bytes correspond to the UDPv4 checksum and once we don't enable clearing the checksum when using L2 frames then the frame doesn't seem to be changed anymore.

2025-05-28calipso: Don't call calipso functions for AF_INET sk.Kuniyuki Iwashima
syzkaller reported a null-ptr-deref in txopt_get(). [0] The offset 0x70 was of struct ipv6_txoptions in struct ipv6_pinfo, so struct ipv6_pinfo was NULL there. However, this never happens for IPv6 sockets as inet_sk(sk)->pinet6 is always set in inet6_create(), meaning the socket was not IPv6 one. The root cause is missing validation in netlbl_conn_setattr(). netlbl_conn_setattr() switches branches based on struct sockaddr.sa_family, which is passed from userspace. However, netlbl_conn_setattr() does not check if the address family matches the socket. The syzkaller must have called connect() for an IPv6 address on an IPv4 socket. We have a proper validation in tcp_v[46]_connect(), but security_socket_connect() is called in the earlier stage. Let's copy the validation to netlbl_conn_setattr().

'net_sched-hfsc-address-reentrant-enqueue-adding-class-to-eltree-twice' Pedro Tammela says: ==================== net_sched: hfsc: Address reentrant enqueue adding class to eltree twice Savino says: "We are writing to report that this recent patch (141d34391abbb315d68556b7c67ad97885407547) can be bypassed, and a UAF can still occur when HFSC is utilized with NETEM. The patch only checks the cl->cl_nactive field to determine whether it is the first insertion or not, but this field is only incremented by init_vf. By using HFSC_RSC (which uses init_ed), it is possible to bypass the check and insert the class twice in the eltree. Under normal conditions, this would lead to an infinite loop in hfsc_dequeue for the reasons we already explained in this report. However, if TBF is added as root qdisc and it is configured with a very low rate, it can be utilized to prevent packets from being dequeued.

2025-05-28net_sched: hfsc: Address reentrant enqueue adding class to eltree twicePedro Tammela
Savino says: "We are writing to report that this recent patch (141d34391abbb315d68556b7c67ad97885407547) [1] can be bypassed, and a UAF can still occur when HFSC is utilized with NETEM. The patch only checks the cl->cl_nactive field to determine whether it is the first insertion or not [2], but this field is only incremented by init_vf [3]. By using HFSC_RSC (which uses init_ed) [4], it is possible to bypass the check and insert the class twice in the eltree. Under normal conditions, this would lead to an infinite loop in hfsc_dequeue for the reasons we already explained in this report [5]. However, if TBF is added as root qdisc and it is configured with a very low rate, it can be utilized to prevent packets from being dequeued. This behavior can be exploited to perform subsequent insertions in the HFSC eltree and cause a UAF." To fix both the UAF and the infinite loop, with netem as an hfsc child, check explicitly in hfsc_enqueue whether the class is already in the eltree whenever the HFSC_RSC flag is set.

2025-05-28octeontx2-pf: QOS: Refactor TC_HTB_LEAF_DEL_LAST callbackHariprasad Kelam
This patch addresses below issues, 1. Active traffic on the leaf node must be stopped before its send queue is reassigned to the parent. This patch resolves the issue by marking the node as 'Inner'. 2. During a system reboot, the interface receives TC_HTB_LEAF_DEL and TC_HTB_LEAF_DEL_LAST callbacks to delete its HTB queues. In the case of TC_HTB_LEAF_DEL_LAST, although the same send queue is reassigned to the parent, the current logic still attempts to update the real number of queues, leadning to below warnings New queues can't be registered after device unregistration.

However, this turned out to not scale very well especially with memcg using rstat for internal operations which made memcg stat read and flush patterns substantially different from other controllers. JP Kobryn split the rstat tree per controller. - cgroup BPF support was hooking into cgroup init/exit paths directly. Convert them to use a notifier chain instead so that other usages can be added easily. The two of the patches which implement this are mislabeled as belonging to sched_ext instead of cgroup.

The test should be improved further to send more data, but for now this should be a welcome improvement. The test will send a repeating pattern of 0x01, 0x02, ... 0x06. The ncdevmem `-v 7` flag will verify this pattern. ncdevmem will provide useful debugging info when the test fails, such as the frags received and verified fine, and which frag exactly failed, what was the expected byte pattern, and what is the actual byte pattern received.
