> Then, Why did you say that ping replies (ICMP echo > replies) were not associated with a socket? Because your crashes where caused by blindly assuming the sk would never be NULL in xfrm_lookup(), and it clearly was. The simple debugging printk() I suggested you insert with your code would have shown you that that was the reason for your crashes. And if I was feeling nice that day, which is possible, since it was Christmas Eve, I may have even put the printk() in myself and tested. > Is there any difference between the special purpose > socket and the socket you mentioned above? I have no idea. You have the code, and probably as much understanding of the networking stack as I do. I suggest you use find and grep to track down the what you are interested in, and how xfrm_lookup() is called in various situations. Take good notes, especially about avenues of exploration that come time mind as you chase one code path. It's not very hard, it's how I learned. -- Dave Dillow <[EMAIL PROTECTED]> - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
