      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: sparx5: fix sleep in atomic context in MAC table access\n\nsparx5_set_rx_mode() runs with netif_addr_lock_bh held and iterates\ndev->mc via __dev_mc_sync(), which per address calls sparx5_mc_sync() /\nsparx5_mc_unsync() -> sparx5_mact_learn() / sparx5_mact_forget().  These\ntake sparx5->lock, a mutex, and then poll the MAC access command\nregister with readx_poll_timeout(). A mutex may block, which is not\nallowed from atomic context.\n\nConvert the driver to the new .ndo_set_rx_mode_async callback introduced\nin commit 3554b4345d85 (\"net: introduce ndo_set_rx_mode_async and\nnetdev_rx_mode_work\"). The async callback is invoked from process\ncontext, so the mutex and sleeping completion poll can remain.\n\nObserved with CONFIG_PROVE_LOCKING, CONFIG_DEBUG_SPINLOCK,\nCONFIG_DEBUG_MUTEXES and CONFIG_DEBUG_ATOMIC_SLEEP enabled:\n\n  BUG: sleeping function called from invalid context at kernel/locking/mutex.c:591\n  in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 217, name: ip\n  preempt_count: 201, expected: 0\n  Call trace:\n   __might_resched+0x144/0x248\n   __might_sleep+0x48/0x7c\n   __mutex_lock+0x74/0x850\n   mutex_lock_nested+0x24/0x30\n   sparx5_mact_learn+0x78/0x100\n   sparx5_mc_sync+0x40/0x54\n   __hw_addr_sync_dev+0xc4/0x170\n   sparx5_set_rx_mode+0x4c/0x58\n   __dev_set_rx_mode+0x64/0xa4\n   __dev_open+0x1ec/0x26c",
