Remi Pommarel 5e43540c2a mac80211: mesh: Free pending skb when destroying a mpath ... A mpath object can hold reference on a list of skb that are waiting for mpath resolution to be sent. When destroying a mpath this skb list should be cleaned up in order to not leak memory. Fixing that kind of leak: unreferenced object 0xffff0000181c9300 (size 1088): comm "openvpn", pid 1782, jiffies 4295071698 (age 80.416s) hex dump (first 32 bytes): 00 00 00 00 00 00 00 00 f9 80 36 00 00 00 00 00 ..........6..... 02 00 07 40 00 00 00 00 00 00 00 00 00 00 00 00 ...@............ backtrace: [<000000004bc6a443>] kmem_cache_alloc+0x1a4/0x2f0 [<000000002caaef13>] sk_prot_alloc.isra.39+0x34/0x178 [<00000000ceeaa916>] sk_alloc+0x34/0x228 [<00000000ca1f1d04>] inet_create+0x198/0x518 [<0000000035626b1c>] __sock_create+0x134/0x328 [<00000000a12b3a87>] __sys_socket+0xb0/0x158 [<00000000ff859f23>] __arm64_sys_socket+0x40/0x58 [<00000000263486ec>] el0_svc_handler+0xd0/0x1a0 [<0000000005b5157d>] el0_svc+0x8/0xc unreferenced object 0xffff000012973a40 (size 216): comm "openvpn", pid 1782, jiffies 4295082137 (age 38.660s) hex dump (first 32 bytes): 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00 c0 06 16 00 00 ff ff 00 93 1c 18 00 00 ff ff ................ backtrace: [<000000004bc6a443>] kmem_cache_alloc+0x1a4/0x2f0 [<0000000023c8c8f9>] __alloc_skb+0xc0/0x2b8 [<000000007ad950bb>] alloc_skb_with_frags+0x60/0x320 [<00000000ef90023a>] sock_alloc_send_pskb+0x388/0x3c0 [<00000000104fb1a3>] sock_alloc_send_skb+0x1c/0x28 [<000000006919d2dd>] __ip_append_data+0xba4/0x11f0 [<0000000083477587>] ip_make_skb+0x14c/0x1a8 [<0000000024f3d592>] udp_sendmsg+0xaf0/0xcf0 [<000000005aabe255>] inet_sendmsg+0x5c/0x80 [<000000008651ea08>] __sys_sendto+0x15c/0x218 [<000000003505c99b>] __arm64_sys_sendto+0x74/0x90 [<00000000263486ec>] el0_svc_handler+0xd0/0x1a0 [<0000000005b5157d>] el0_svc+0x8/0xc Fixes: 2bdaf386f9 (mac80211: mesh: move path tables into if_mesh) Signed-off-by: Remi Pommarel <repk@triplefau.lt> Link: https://lore.kernel.org/r/20200704135419.27703-1-repk@triplefau.lt Signed-off-by: Johannes Berg <johannes.berg@intel.com>		2020-07-30 10:23:48 +02:00
