Конфиг интерфейсов следующий: - eth0 и eth1 объеденены в группу с помощью модуля bonding; - интефейс bond0 настроен как 802.1Q-транк (пропуск VLAN'ов на коммутатор); - добавлен VLAN200 (имя интерфейса bond0.200) Далее: # ip link set bond0.200 name vlan0200 Segmentation fault # dmesg .... bonding: Warning: Cannot create /proc/net/bonding/<NULL> Unable to handle kernel NULL pointer dereference at virtual address 00000338 printing eip: c01960a7 *pde = 371f9001 *pte = 35d1c067 Oops: 0000 [#1] SMP Modules linked in: bond0 loop ac thermal processor button tsdev pcspkr psmouse 8021q sg hw_random ehci_hcd i2c_i801 i2c_core uhci_hcd e752x_edac usbcore edac_mc dm_mod e1000 rtc ext3 jbd mbcache megaraid_mbox megaraid_mm sd_mod scsi_mod ide_disk ide_generic generic piix ide_core CPU: 1, VCPU: 0:0 EIP: 0060:[<c01960a7>] Not tainted VLI EFLAGS: 00010202 (2.6.16-ovz-smp-alt12 #1) EIP is at sysfs_remove_group+0x2f/0x9c eax: 00000000 ebx: f8a623ac ecx: 00000007 edx: f8a623ac esi: 00000308 edi: f8a5cb62 ebp: 00000000 esp: f5d39edc ds: 007b es: 007b ss: 0068 Process ip (pid: 16599, veid=0, threadinfo=f5d38000 task=dfc08db0) Stack: <0>f8a62ae4 f73ec400 0000000a f8a52c5f f8a6210c f73ec000 c01299ed f73ec000 f73ec010 f5d39f34 c02274b1 fffffdfd f5d39f24 00008923 f5d39f24 c022912d 00000000 bfcd7a94 646e6f62 30322e30 00000030 00000000 6e616c76 30303230 Call Trace: [<f8a52c5f>] bond_event_changename+0x2f/0x4c [bond0] [<c01299ed>] notifier_call_chain+0x17/0x29 [<c02274b1>] dev_change_name+0x12b/0x134 [<c022912d>] dev_ioctl+0x2a2/0x3de [<c021fb3f>] sock_ioctl+0x1d1/0x1da [<c021f96e>] sock_ioctl+0x0/0x1da [<c016ebbb>] do_ioctl+0x23/0x60 [<c016ee7a>] vfs_ioctl+0x187/0x195 [<c016eece>] sys_ioctl+0x46/0x60 [<c0102959>] syscall_call+0x7/0xb Code: c6 b8 00 e0 ff ff 89 d3 21 e0 8b 00 8b 80 90 05 00 00 83 b8 0c 01 00 00 00 74 79 8b 3a 85 ff 74 18 31 c0 83 c9 ff f2 ae f7 d1 49 <8b> 56 30 8b 03 e8 bd 5d fd ff 89 c7 eb 3c 8b 56 30 85 d2 74 33
