 |

Hi all,
This post is just to share a iscsi-problem I had when using the svn truck iscsi-target from https://iscsitarget.svn.sourceforge.net/svnroot/iscsitarget
Firstly, the kernel module failed during compilation with the following error:
| Code: |
iscsitarget/trunk/kernel/wthread.c: In function ‘worker_thread’:
iscsitarget/trunk/kernel/wthread.c:74:3: error: implicit declaration of function ‘get_task_io_context’
iscsitarget/trunk/kernel/wthread.c:74:21: warning: assignment makes pointer from integer without a cast
make[2]: *** [iscsitarget/trunk/kernel/wthread.o] Error 1
make[1]: *** [_module_/home/wltsang/iscsitarget/trunk/kernel] Error 2
|
This is fixed by applying the patch:
| Code: |
patch -p1 < patches/compat-2.6.39-3.2.patch
patching file kernel/wthread.c
|
But now, after the kernel module has been compiled successfully, the module will not load. It simply returns "Cannot allocate memory" without any error.
After some debugging, I found the following change is required to load the module in hardened-3.2.2-r1:
| Code: |
int event_init(void)
{
- nl = netlink_kernel_create(&init_net, NETLINK_IET, 1, event_recv_skb,
+ nl = netlink_kernel_create(&init_net, NETLINK_ISCSI, 1, event_recv_skb,
NULL, THIS_MODULE);
|
After this change, the module loads fine without issue so far.

No problem. But I found that there is a better way, which is to update iet_u.h:
| Code: |
#define NETLINK_IET 23
|
It is because number 21 is already used by CRC32
