From: David Woodhouse Date: Sun, 10 May 2009 05:54:21 +0000 (-0700) Subject: tun: add tun_flags, owner, group attributes in sysfs X-Git-Tag: v2.6.31-rc1~330^2~437 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=980c9e8ceeb69ac4c921173d0d06323f5c678647;p=pandora-kernel.git tun: add tun_flags, owner, group attributes in sysfs This patch adds three attribute files in /sys/class/net/$dev/ for tun devices; allowing userspace to obtain the information which TUNGETIFF offers, and more, but without having to attach to the device in question (which may not be possible if it's in use). It also fixes a bug which has been present in the TUNGETIFF ioctl since its inception, where it would never set IFF_TUN or IFF_TAP according to the device type. (Look carefully at the code which I remove from tun_get_iff() and how the new tun_flags() helper is subtly different). Signed-off-by: David Woodhouse Signed-off-by: David S.
