The comment for idr_for_each_entry_ul() states after normal termination @entry is left with the value NULL This is not correct in the case where UINT_MAX has an entry in the idr. In that case @entry will be non-NULL after termination. No current code depends on the documentation being correct, but to save future code we should fix it. Also fix idr_for_each_entry_continue_ul(). While this is not documented as leaving @entry as NULL, the mellanox driver appears to depend on it doing so. So make that explicit in the documentation as well as in the code.

RTL8168H and RTL8107E ethernet adapters erroneously filter unicast eapol packets unless allmulti is enabled. These devices correspond to RTL_GIGA_MAC_VER_46 and VER_48.

Initially, commit 4237c75c ("[MLSXFRM]: Auto-labeling of child sockets") introduced security_inet_conn_request() in some functions where reqsk is allocated. The hook is added just after the allocation, so reqsk's IPv6 remote address was not initialised then. However, SELinux/Smack started to read it in netlbl_req_setattr() after commit e1adea92 ("calipso: Allow request sockets to be relabelled by the lsm."). Commit 284904aa ("lsm: Relocate the IPv4 security_inet_conn_request() hooks") fixed that kind of issue only in TCPv4 because IPv6 labeling was not supported at that time. Finally, the same issue was introduced again in IPv6. Let's apply the same fix on DCCPv6 and TCPv6. Fixes: e1adea92 ("calipso: Allow request sockets to be relabelled by the lsm.") Signed-off-by:

Since commit 833bac7e ("net/smc: Fix setsockopt and sysctl to specify same buffer size again") the SMC protocol uses its own default values for the smc.rmem and smc.wmem sysctl variables which are no longer derived from the TCP IPv4 buffer sizes.

When LAN9303 is MDIO-connected two callchains exist into mdio->bus->write(): 1. switch ports 1&2 ("physical" PHYs): virtual (switch-internal) MDIO bus (lan9303_switch_ops->phy_{read|write})-> lan9303_mdio_phy_{read|write} -> mdiobus_{read|write}_nested 2. LAN9303 virtual PHY: virtual MDIO bus (lan9303_phy_{read|write}) -> lan9303_virt_phy_reg_{read|write} -> regmap -> lan9303_mdio_{read|write} If the latter functions just take mutex_lock(&sw_dev->device->bus->mdio_lock) it triggers a LOCKDEP false-positive splat. It's false-positive because the first mdio_lock in the second callchain above belongs to virtual MDIO bus, the second mdio_lock belongs to physical MDIO bus. Consequent annotation in lan9303_mdio_{read|write} as nested lock (similar to lan9303_mdio_phy_{read|write}, it's the same physical MDIO bus) prevents the following splat: WARNING: possible circular locking dependency detected 5.15.71 #1 Not tainted ------------------------------------------------------ kworker/u4:3/609 is trying to acquire lock: ffff000011531c68 (lan9303_mdio:131:(&lan9303_mdio_regmap_config)->lock){+.+.}-{3:3}, at: regmap_lock_mutex but task is already holding lock: ffff0000114c44d8 (&bus->mdio_lock){+.+.}-{3:3}, at: mdiobus_read which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #1 (&bus->mdio_lock){+.+.}-{3:3}: lock_acquire __mutex_lock mutex_lock_nested lan9303_mdio_read _regmap_read regmap_read lan9303_probe lan9303_mdio_probe mdio_probe really_probe __driver_probe_device driver_probe_device __device_attach_driver bus_for_each_drv __device_attach device_initial_probe bus_probe_device deferred_probe_work_func process_one_work worker_thread kthread ret_from_fork -> #0 (lan9303_mdio:131:(&lan9303_mdio_regmap_config)->lock){+.+.}-{3:3}: __lock_acquire lock_acquire.part.0 lock_acquire __mutex_lock mutex_lock_nested regmap_lock_mutex regmap_read lan9303_phy_read dsa_slave_phy_read __mdiobus_read mdiobus_read get_phy_device mdiobus_scan __mdiobus_register dsa_register_switch lan9303_probe lan9303_mdio_probe mdio_probe really_probe __driver_probe_device driver_probe_device __device_attach_driver bus_for_each_drv __device_attach device_initial_probe bus_probe_device deferred_probe_work_func process_one_work worker_thread kthread ret_from_fork other info that might help us debug this: Possible unsafe locking scenario: CPU0 CPU1 ---- ---- lock(&bus->mdio_lock); lock(lan9303_mdio:131:(&lan9303_mdio_regmap_config)->lock); lock(&bus->mdio_lock); lock(lan9303_mdio:131:(&lan9303_mdio_regmap_config)->lock); *** DEADLOCK *** 5 locks held by kworker/u4:3/609: #0: ffff000002842938 ((wq_completion)events_unbound){+.+.}-{0:0}, at: process_one_work #1: ffff80000bacbd60 (deferred_probe_work){+.+.}-{0:0}, at: process_one_work #2: ffff000007645178 (&dev->mutex){....}-{3:3}, at: __device_attach #3: ffff8000096e6e78 (dsa2_mutex){+.+.}-{3:3}, at: dsa_register_switch #4: ffff0000114c44d8 (&bus->mdio_lock){+.+.}-{3:3}, at: mdiobus_read stack backtrace: CPU: 1 PID: 609 Comm: kworker/u4:3 Not tainted 5.15.71 #1 Workqueue: events_unbound deferred_probe_work_func Call trace: dump_backtrace show_stack dump_stack_lvl dump_stack print_circular_bug check_noncircular __lock_acquire lock_acquire.part.0 lock_acquire __mutex_lock mutex_lock_nested regmap_lock_mutex regmap_read lan9303_phy_read dsa_slave_phy_read __mdiobus_read mdiobus_read get_phy_device mdiobus_scan __mdiobus_register dsa_register_switch lan9303_probe lan9303_mdio_probe ...

This resolves the issue by ensuring that only null-terminated strings are accepted as bearer-related names. syzbot reported similar uninit-value issue related to bearer names [2].

There are further uses in include/net/llc_pdu.h. All these are protected by a test skb->protocol == ETH_P_802_2. Which does not protect against this tun scenario. But the mac_len test added in this patch in llc_fixup_skb will indirectly protect those too. That is called from llc_rcv before any other LLC code. It is tempting to just add a blanket mac_len check in llc_rcv, but not sure whether that could break valid LLC paths that do not assume an Ethernet header. 802.2 LLC may be used on top of non-802.3 protocols in principle. The below referenced commit shows that used to, on top of Token Ring. At least one of the three eth_hdr uses goes back to before the start of git history. But the one that syzbot exercises is introduced in this commit. That commit is old enough (2008), that effectively all stable kernels should receive this.

Pull probes updates from Masami Hiramatsu: "Cleanups: - kprobes: Fixes typo in kprobes samples - tracing/eprobes: Remove 'break' after return kretprobe/fprobe performance improvements: - lib: Introduce new `objpool`, which is a high performance lockless object queue. This uses per-cpu ring array to allocate/release objects from the pre-allocated object pool. Since the index of ring array is a 32bit sequential counter, we can retry to push/pop the object pointer from the ring without lock (as seq-lock does) - lib: Add an objpool test module to test the functionality and evaluate the performance under some circumstances - kprobes/fprobe: Improve kretprobe and rethook scalability performance with objpool. This improves both legacy kretprobe and fprobe exit handler (which is based on rethook) to be scalable on SMP systems. Even with 8-threads parallel test, it shows a great scalability improvement - Remove unneeded freelist.h which is replaced by objpool - objpool: Add maintainers entry for the objpool - objpool: Fix to remove unused include header lines" * tag 'probes-v6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: kprobes: unused header files removed MAINTAINERS: objpool added kprobes: freelist.h removed kprobes: kretprobe scalability improvement lib: objpool test module added lib: objpool added: ring-array based lockless MPMC tracing/eprobe: drop unneeded breaks samples: kprobes: Fixes a typo -

Pull VFIO updates from Alex Williamson: - Add support for "chunk mode" in the mlx5-vfio-pci variant driver, which allows both larger device image sizes for migration, beyond the previous 4GB limit, and also read-ahead support for improved migration performance (Yishai Hadas) - A new bus master control interface for the CDX bus driver where there is no in-band mechanism to toggle device DMA as there is through config space on PCI devices (Nipun Gupta) - Add explicit alignment directives to vfio data structures to reduce the chance of breaking 32-bit userspace. In most cases this is transparent and the remaining cases where data structures are padded work within the existing rules for extending data structures within vfio (Stefan Hajnoczi) - Resolve a bug in the cdx bus driver noted when compiled with clang where missing parenthesis result in the wrong operation (Nathan Chancellor) - Resolve errors reported by smatch for a function when dealing with invalid inputs (Alex Williamson) - Add migration support to the mtty vfio/mdev sample driver for testing and integration purposes, allowing CI of migration without specific hardware requirements.
