"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: dsa: mv88e6xxx: don't use devres for mdiobus\n\nAs explained in commits:\n74b6d7d13307 (\"net: dsa: realtek: register the MDIO bus under devres\")\n5135e96a3dd2 (\"net: dsa: don't allocate the slave_mii_bus using devres\")\n\nmdiobus_free() will panic when called from devm_mdiobus_free() <-\ndevres_release_all() <- __device_release_driver(), and that mdiobus was\nnot previously unregistered.\n\nThe mv88e6xxx is an MDIO device, so the initial set of constraints that\nI thought would cause this (I2C or SPI buses which call ->remove on\n->shutdown) do not apply. But there is one more which applies here.\n\nIf the DSA master itself is on a bus that calls ->remove from ->shutdown\n(like dpaa2-eth, which is on the fsl-mc bus), there is a device link\nbetween the switch and the DSA master, and device_links_unbind_consumers()\nwill unbind the Marvell switch driver on shutdown.\n\nsystemd-shutdown[1]: Powering off.\nmv88e6085 0x0000000008b96000:00 sw_gl0: Link is Down\nfsl-mc dpbp.9: Removing from iommu group 7\nfsl-mc dpbp.8: Removing from iommu group 7\n------------[ cut here ]------------\nkernel BUG at drivers/net/phy/mdio_bus.c:677!\nInternal error: Oops - BUG: 0 [#1] PREEMPT SMP\nModules linked in:\nCPU: 0 PID: 1 Comm: systemd-shutdow Not tainted 5.16.5-00040-gdc05f73788e5 #15\npc : mdiobus_free+0x44/0x50\nlr : devm_mdiobus_free+0x10/0x20\nCall trace:\n mdiobus_free+0x44/0x50\n devm_mdiobus_free+0x10/0x20\n devres_release_all+0xa0/0x100\n __device_release_driver+0x190/0x220\n device_release_driver_internal+0xac/0xb0\n device_links_unbind_consumers+0xd4/0x100\n __device_release_driver+0x4c/0x220\n device_release_driver_internal+0xac/0xb0\n device_links_unbind_consumers+0xd4/0x100\n __device_release_driver+0x94/0x220\n device_release_driver+0x28/0x40\n bus_remove_device+0x118/0x124\n device_del+0x174/0x420\n fsl_mc_device_remove+0x24/0x40\n __fsl_mc_device_remove+0xc/0x20\n device_for_each_child+0x58/0xa0\n dprc_remove+0x90/0xb0\n fsl_mc_driver_remove+0x20/0x5c\n __device_release_driver+0x21c/0x220\n device_release_driver+0x28/0x40\n bus_remove_device+0x118/0x124\n device_del+0x174/0x420\n fsl_mc_bus_remove+0x80/0x100\n fsl_mc_bus_shutdown+0xc/0x1c\n platform_shutdown+0x20/0x30\n device_shutdown+0x154/0x330\n kernel_power_off+0x34/0x6c\n __do_sys_reboot+0x15c/0x250\n __arm64_sys_reboot+0x20/0x30\n invoke_syscall.constprop.0+0x4c/0xe0\n do_el0_svc+0x4c/0x150\n el0_svc+0x24/0xb0\n el0t_64_sync_handler+0xa8/0xb0\n el0t_64_sync+0x178/0x17c\n\nSo the same treatment must be applied to all DSA switch drivers, which\nis: either use devres for both the mdiobus allocation and registration,\nor don't use devres at all.\n\nThe Marvell driver already has a good structure for mdiobus removal, so\njust plug in mdiobus_free and get rid of devres."
