bond: Simply bond sysfs group creation

This patch delegates the work of creating the sysfs groups
to the netdev layer and ultimately to the device layer.  This
closes races between uevents.

proto_ops->getname implies copying protocol specific data

So when we implement new protocol support we should keep such

Lets introduce DECLARE_SOCKADDR helper which check if

10 years agoAF_RAW: Augment raw_send_hdrinc to expand skb to fit iphdr->ihl (v2)
Neil Horman [Wed, 28 Oct 2009 08:59:47 +0000]
AF_RAW: Augment raw_send_hdrinc to expand skb to fit iphdr->ihl (v2)

Augment raw_send_hdrinc to correct for incorrect ip header length values

A series of oopses was reported to me recently.  Apparently when using AF_RAW
sockets to send data to peers that were reachable via ipsec encapsulation,
people could panic or BUG halt their systems.

I've tracked the problem down to user space sending an invalid ip header over an
AF_RAW socket with IP_HDRINCL set to 1.

Basically what happens is that userspace sends down an ip frame that includes
only the header (no data), but sets the ip header ihl value to a large number,
one that is larger than the total amount of data passed to the sendmsg call.  In
raw_send_hdrincl, we allocate an skb based on the size of the data in the msghdr
that was passed in, but assume the data is all valid.  Later during ipsec
encapsulation, xfrm4_tranport_output moves the entire frame back in the skbuff
to provide headroom for the ipsec headers.  During this operation, the
skb->transport_header is repointed to a spot computed by
skb->network_header + the ip header length (ihl).  Since so little data was
passed in relative to the value of ihl provided by the raw socket, we point
transport header to an unknown location, resulting in various crashes.

This fix for this is pretty straightforward, simply validate the value of of
iph->ihl when sending over a raw socket.  If (iph->ihl*4U) > user data buffer
size, drop the frame and return -EINVAL.  I just confirmed this fixes the
reported crashes.

bonding: fix a race condition in calls to slave MII ioctls

In mii monitor mode, bond_check_dev_link() calls the the ioctl
handler of slave devices. It stores the ndo_do_ioctl function
pointer to a static (!) ioctl variable and later uses it to call the
handler with the IOCTL macro.

If another thread executes bond_check_dev_link() at the same time
(even with a different bond, which none of the locks prevent), a
race condition occurs. If the two racing slaves have different
drivers, this may result in one driver's ioctl handler being
called with a pointer to a net_device controlled with a different
driver, resulting in unpredictable breakage.

Unless I am overlooking something, the "static" must be a
copy'n'paste error (?).
