Cong Wang fa7c336dd1 atm: fix a memory leak of vcc->user_back ... [ Upstream commit 8d9f73c0ad ] In lec_arp_clear_vccs() only entry->vcc is freed, but vcc could be installed on entry->recv_vcc too in lec_vcc_added(). This fixes the following memory leak: unreferenced object 0xffff8880d9266b90 (size 16): comm "atm2", pid 425, jiffies 4294907980 (age 23.488s) hex dump (first 16 bytes): 00 00 00 00 00 00 00 00 00 00 00 00 6b 6b 6b a5 ............kkk. backtrace: [<(____ptrval____)>] kmem_cache_alloc_trace+0x10e/0x151 [<(____ptrval____)>] lane_ioctl+0x4b3/0x569 [<(____ptrval____)>] do_vcc_ioctl+0x1ea/0x236 [<(____ptrval____)>] svc_ioctl+0x17d/0x198 [<(____ptrval____)>] sock_do_ioctl+0x47/0x12f [<(____ptrval____)>] sock_ioctl+0x2f9/0x322 [<(____ptrval____)>] vfs_ioctl+0x1e/0x2b [<(____ptrval____)>] ksys_ioctl+0x61/0x80 [<(____ptrval____)>] __x64_sys_ioctl+0x16/0x19 [<(____ptrval____)>] do_syscall_64+0x57/0x65 [<(____ptrval____)>] entry_SYSCALL_64_after_hwframe+0x49/0xb3 Cc: Gengming Liu <l.dmxcsnsbh@gmail.com> Signed-off-by: Cong Wang <xiyou.wangcong@gmail.com> Signed-off-by: David S.
