Hello, I've been experiencing really strange behaviours with the 2 latest hardened kernels (2.6.14-r6 and r7) on 2 different machines that are both used as OpenVPN concentrators. 2.6.14-r5 is working fine on these machines.
The phenomenon is the following. When I connect to the openvpn server from remote with openvpn, a connection is established (from the view of the client) but in the same moment the server crashes. This is what I managed to capture with netconsole: Unable to handle kernel paging request at virtual address 00695052 printing eip: *pgd = 0 *pmd = 0 Oops: 0000 [#1] Modules linked in: netconsole w83781d hwmon_vid hwmon i2c_isa ip6table_filter cls_fw sch_sfq sch_htb cls_u32 bsd_comp ppp_synctty ppp_async crc_ccitt ppp_generic slhc ipt_DSCP ipt_tos ipt_length ipt_TCPMSS i2c_viapro i2c_core parport_pc loop CPU: 0 EIP: 0060:[<00000001>] Not tainted VLI EFLAGS: 00010286 (2.6.14-hardened-r7) EIP is at checkCPUtype+0xfffffefc/0x81 eax: c0c25a20 ebx: 00000000 ecx: f793e4e0 edx: f5b89640 esi: 0028d4f0 edi: c0c95240 ebp: 00289370 esp: c0c56e70 ds: 007b es: 007b ss: 0068 Process openvpn (pid: 24564, threadinfo=c0c56000 task=f730e070) Stack: 0028d5c1 f5b89640 00000001 c0c95300 00000000 0028d4f0 c0c95240 00289370 0028de4b f5b89640 00000000 c0c56ec0 f6c3c000 I first though it was machine related (hardware) but as it now happened on a second machine, I'm not sure anymore... I tried to recompile openvpn and the kernel (one machine has gcc 3.3.6 - the other one 3.4.5): it didn't help. I'm unsure where to start looking for the problem. Is it a flaw in OpenVPN or could it be caused by one of the patches included in 2.4.15-r6? Thanks for your advice.
