Ben Chan 9f77186dd1 staging: gdm72xx: Release netlink socket properly ... This patch modifies the gdm72xx driver to properly release a netlink socket using netlink_kernel_release. It fixes the following kernel crash, which occurs after repeatedly suspending and resuming a system. kernel BUG at /home/benchan/trunk/src/third_party/kernel/files/mm/slub.c:3471! invalid opcode: 0000 [#1] SMP CPU 2 Modules linked in: asix usbnet snd_hda_codec_hdmi snd_hda_codec_cirrus i2c_dev uinput snd_hda_intel snd_hda_codec snd_hwdep snd_pcm snd_timer bluetooth snd_page_alloc fuse aesni_intel cryptd isl29018(C) aes_x86_64 industrialio(C) memconsole nm10_gpio rtc_cmos nf_conntrack_ipv6 nf_defrag_ipv6 r8169 ath9k mac80211 ip6table_filter ath9k_common ath9k_hw ath cfg80211 xt_mark ip6_tables uvcvideo videobuf2_core videodev videobuf2_vmalloc videobuf2_memops gdmwm(C) joydev Pid: 3125, comm: kworker/u:30 Tainted: G WC 3.4.0 #1 RIP: 0010:[<ffffffff810cda19>] [<ffffffff810cda19>] kfree+0x67/0xca RSP: 0018:ffff880134977d60 EFLAGS: 00010246 RAX: 4000000000000400 RBX: ffffffff818832a0 RCX: 0000000000000000 RDX: 4000000000000000 RSI: 0000000000000000 RDI: ffffffff818832a0 RBP: ffff880134977d80 R08: 00000000ffffffff R09: ffffea00000620c0 R10: ffffffff8111b729 R11: ffff880149fb3840 R12: ffffffff81a08840 R13: ffffffff813f5bc3 R14: ffffffff8138ed84 R15: 0000000000000000 FS: 0000000000000000(0000) GS:ffff88014fb00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: 00007f7cad963110 CR3: 000000000180b000 CR4: 00000000000407e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process kworker/u:30 (pid: 3125, threadinfo ffff880134976000, task ffff8801330647e0) Stack: 0000000000000002 ffffffff818832a0 ffffffff81a08840 ffff880134977df0 ffff880134977da0 ffffffff813f5bc3 ffff880134977df0 ffffffff81883250 ffff880134977dd0 ffffffff8138e64c 0000000180150010 ffffffff81883250 Call Trace: [<ffffffff813f5bc3>] ipv4_sysctl_exit_net+0x23/0x27 [<ffffffff8138e64c>] ops_exit_list+0x27/0x50 [<ffffffff8138ee72>] cleanup_net+0xee/0x17c [<ffffffff81040c64>] process_one_work+0x199/0x2b8 [<ffffffff810416e4>] worker_thread+0x13c/0x222 [<ffffffff810415a8>] ? manage_workers.isra.26+0x171/0x171 [<ffffffff8104506d>] kthread+0x8b/0x93 [<ffffffff8145b414>] kernel_thread_helper+0x4/0x10 [<ffffffff81044fe2>] ? __init_kthread_worker+0x39/0x39 [<ffffffff8145b410>] ? gs_change+0xb/0xb Code: 83 c4 10 49 83 3c 24 00 eb e4 48 83 fb 10 76 76 48 89 df e8 17 e1 ff ff 49 89 c1 48 8b 00 a8 80 75 15 49 f7 01 00 c0 00 00 75 02 <0f> 0b 4c 89 cf e8 b8 b4 fd ff eb 4f 4c 8b 55 08 49 8b 79 30 48 RIP [<ffffffff810cda19>] kfree+0x67/0xca RSP <ffff880134977d60> Signed-off-by: Ben Chan <benchan@chromium.org> Cc: Sage Ahn <syahn@gctsemi.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2012-06-14 17:28:46 -07:00
