In the Linux kernel, the following vulnerability has been resolved: idpf: convert control queue mutex to a spinlock With VIRTCHNL2_CAP_MACFILTER enabled, the following warning is generated on module load: [ 324.701677] BUG: sleeping function called from invalid context at kernel/locking/mutex.c:578 [ 324.701684] in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 1582, name: NetworkManager [ 324.701689] preempt_count: 201, expected: 0 [ 324.701693] RCU nest depth: 0, expected: 0 [ 324.701697] 2 locks held by NetworkManager/1582: [ 324.701702] #0: ffffffff9f7be770 (rtnl_mutex){....}-{3:3}, at: rtnl_newlink+0x791/0x21e0 [ 324.701730] #1: ff1100216c380368 (_xmit_ETHER){....}-{2:2}, at: __dev_open+0x3f0/0x870 [ 324.701749] Preemption disabled at: [ 324.701752] [<ffffffff9cd23b9d>] __dev_open+0x3dd/0x870 [ 324.701765] CPU: 30 UID: 0 PID: 1582 Comm: NetworkManager Not tainted 6.15.0-rc5+ #2 PREEMPT(voluntary) [ 324.701771] Hardware name: Intel Corporation M50FCP2SBSTD/M50FCP2SBSTD, BIOS SE5C741.86B.01.01.0001.2211140926 11/14/2022 [ 324.701774] Call Trace: [ 324.701777] <TASK> [ 324.701779] dump_stack_lvl+0x5d/0x80 [ 324.701788] ? __dev_open+0x3dd/0x870 [ 324.701793] __might_resched.cold+0x1ef/0x23d <..> [ 324.701818] __mutex_lock+0x113/0x1b80 <..> [ 324.701917] idpf_ctlq_clean_sq+0xad/0x4b0 [idpf] [ 324.701935] ? kasan_save_track+0x14/0x30 [ 324.701941] idpf_mb_clean+0x143/0x380 [idpf] <..> [ 324.701991] idpf_send_mb_msg+0x111/0x720 [idpf] [ 324.702009] idpf_vc_xn_exec+0x4cc/0x990 [idpf] [ 324.702021] ? rcu_is_watching+0x12/0xc0 [ 324.702035] idpf_add_del_mac_filters+0x3ed/0xb50 [idpf] <..> [ 324.702122] __hw_addr_sync_dev+0x1cf/0x300 [ 324.702126] ? find_held_lock+0x32/0x90 [ 324.702134] idpf_set_rx_mode+0x317/0x390 [idpf] [ 324.702152] __dev_open+0x3f8/0x870 [ 324.702159] ? __pfx___dev_open+0x10/0x10 [ 324.702174] __dev_change_flags+0x443/0x650 <..> [ 324.702208] netif_change_flags+0x80/0x160 [ 324.702218] do_setlink.isra.0+0x16a0/0x3960 <..> [ 324.702349] rtnl_newlink+0x12fd/0x21e0 The sequence is as follows: rtnl_newlink()-> __dev_change_flags()-> __dev_open()-> dev_set_rx_mode() - > # disables BH and grabs "dev->addr_list_lock" idpf_set_rx_mode() -> # proceed only if VIRTCHNL2_CAP_MACFILTER is ON __dev_uc_sync() -> idpf_add_mac_filter -> idpf_add_del_mac_filters -> idpf_send_mb_msg() -> idpf_mb_clean() -> idpf_ctlq_clean_sq() # mutex_lock(cq_lock) Fix by converting cq_lock to a spinlock. All operations under the new lock are safe except freeing the DMA memory, which may use vunmap(). Fix by requesting a contiguous physical memory for the DMA mapping.
