But because the symptoms didn't change overly I had my doubts from the beginning, and thus have been trying to prove I was running the kernel with your patch applied. Doing that in various ways is why it took me a while to respond to your request to test the patch. One way I tried to confirm it by adding trace: --- x/linux-2.6-2.6.32/drivers/net/tun.c 2009-12-03 13:51:21.000000000 +1000 +++ linux-2.6-2.6.32/drivers/net/tun.c 2010-09-06 08:09:44.068458190 +1000 @@ -36,7 +36,7 @@ #define DRV_NAME "tun" #define DRV_VERSION "1.6" -#define DRV_DESCRIPTION "Universal TUN/TAP device driver" +#define DRV_DESCRIPTION "Universal TUN/TAP device driver + 0001-tun-Don-t-add-sysfs-attributes-to-devices-without-sy.patch applied" #define DRV_COPYRIGHT "(C) 1999-2004 Max Krasnyansky <m...@qualcomm.com>" #include <linux/module.h> @@ -1006,7 +1006,9 @@ if (err < 0) goto err_free_sk; - if (device_create_file(&tun->dev->dev, &dev_attr_tun_flags) || + printk(KERN_INFO "0001-tun-Don-t-add-sysfs-attributes-to-devices-without-sy.patch\n"); + if (!net_eq(dev_net(tun->dev), &init_net) || + device_create_file(&tun->dev->dev, &dev_attr_tun_flags) || device_create_file(&tun->dev->dev, &dev_attr_owner) || device_create_file(&tun->dev->dev, &dev_attr_group)) printk(KERN_ERR "Failed to create tun sysfs files\n"); None of the trace is ever appears in /var/log/kern.log, which is to say "grep 0001-tun /var/log/kern.log" prints nothing. Yet I am evidently running a different kernel as I don't ever hit the BUG the buildd kernel generates. I don't have a clue what is going on.
