If the mpath\ngets deleted, ex mesh interface is removed, the entries in that list will\nnever get cleaned. Fix this by flushing all corresponding items of the\npreq_queue in mesh_path_flush_pending().\n\nThis should take care of KASAN reports like this:\n\nunreferenced object 0xffff00000668d800 (size 128):\n comm \"kworker/u8:4\", pid 67, jiffies 4295419552 (age 1836.444s)\n hex dump (first 32 bytes):\n 00 1f 05 09 00 00 ff ff 00 d5 68 06 00 00 ff ff ..........h.....\n 8e 97 ea eb 3e b8 01 00 00 00 00 00 00 00 00 00 ....>...........\n backtrace:\n [<000000007302a0b6>] __kmem_cache_alloc_node+0x1e0/0x35c\n [<00000000049bd418>] kmalloc_trace+0x34/0x80\n [<0000000000d792bb>] mesh_queue_preq+0x44/0x2a8\n [<00000000c99c3696>] mesh_nexthop_resolve+0x198/0x19c\n [<00000000926bf598>] ieee80211_xmit+0x1d0/0x1f4\n [<00000000fc8c2284>] __ieee80211_subif_start_xmit+0x30c/0x764\n [<000000005926ee38>] ieee80211_subif_start_xmit+0x9c/0x7a4\n [<000000004c86e916>] dev_hard_start_xmit+0x174/0x440\n [<0000000023495647>] __dev_queue_xmit+0xe24/0x111c\n [<00000000cfe9ca78>] batadv_send_skb_packet+0x180/0x1e4\n [<000000007bacc5d5>] batadv_v_elp_periodic_work+0x2f4/0x508\n [<00000000adc3cd94>] process_one_work+0x4b8/0xa1c\n [<00000000b36425d1>] worker_thread+0x9c/0x634\n [<0000000005852dd5>] kthread+0x1bc/0x1c4\n [<000000005fccd770>] ret_from_fork+0x10/0x20\nunreferenced object 0xffff000009051f00 (size 128):\n comm \"kworker/u8:4\", pid 67, jiffies 4295419553 (age 1836.440s)\n hex dump (first 32 bytes):\n 90 d6 92 0d 00 00 ff ff 00 d8 68 06 00 00 ff ff ..........h.....\n 36 27 92 e4 02 e0 01 00 00 58 79 06 00 00 ff ff 6'.......Xy.....\n backtrace:\n [<000000007302a0b6>] __kmem_cache_alloc_node+0x1e0/0x35c\n [<00000000049bd418>] kmalloc_trace+0x34/0x80\n [<0000000000d792bb>] mesh_queue_preq+0x44/0x2a8\n [<00000000c99c3696>] mesh_nexthop_resolve+0x198/0x19c\n [<00000000926bf598>] ieee80211_xmit+0x1d0/0x1f4\n [<00000000fc8c2284>] __ieee80211_subif_start_xmit+0x30c/0x764\n [<000000005926ee38>] ieee80211_subif_start_xmit+0x9c/0x7a4\n [<000000004c86e916>] dev_hard_start_xmit+0x174/0x440\n [<0000000023495647>] __dev_queue_xmit+0xe24/0x111c\n [<00000000cfe9ca78>] batadv_send_skb_packet+0x180/0x1e4\n [<000000007bacc5d5>] batadv_v_elp_periodic_work+0x2f4/0x508\n [<00000000adc3cd94>] process_one_work+0x4b8/0xa1c\n [<00000000b36425d1>] worker_thread+0x9c/0x634\n [<0000000005852dd5>] kthread+0x1bc/0x1c4\n [<000000005fccd770>] ret_from_fork+0x10/0x20"
