This further patch will allow you to connect via usbnet, Greg could you apply? Thanks! Signed-off-by:

Miscellaneous updates for EHCI. - Mostly updates the power switching on EHCI controllers. One routine centralizes the "power on/off all ports" logic, and the capability to do that is reported more correctly. - Courtesy Colin Leroy, a patch to always power up ports after resumes which didn't keep a USB device suspended. The reset-everything logic powers down those ports (on some hardware) so something needs to turn them back on. - Minor tweaks/bugfixes for the debug port support. Signed-off-by:

I found a bug that stopped IPsec/IPv6 from working. About a month ago IPv6 started using rt6i_idev->dev on the cached socket dst entries. If the cached socket dst entry is IPsec, then rt6i_idev will be NULL. Since we want to look at the rt6i_idev of the original route in this case, the easiest fix is to store rt6i_idev in the IPsec dst entry just as we do for a number of other IPv6 route attributes. Unfortunately this means that we need some new code to handle the references to rt6i_idev. That's why this patch is bigger than it would otherwise be. I've also done the same thing for IPv4 since it is conceivable that once these idev attributes start getting used for accounting, we probably need to dereference them for IPv4 IPsec entries too.

Netem currently dumps packets into the queue when timer expires. This patch makes work by self-clocking (more like TBF). It fixes a bug when 0 delay is requested (only doing loss or duplication). Signed-off-by:

Due to bugs in netem (fixed by later patches), it is possible to get qdisc qlen to go negative. If this happens the CPU ends up spinning forever in qdisc_run(). So add a BUG_ON() to trap it. Signed-off-by:

Some network drivers call netif_stop_queue() when detecting loss of carrier. This leads to packets being queued up at the qdisc level for an unbound period of time. In order to prevent this effect, the core networking stack will now cease to queue packets for any device, that is operationally down (i.e. the queue is flushed and disabled). Signed-off-by:

If we free up a partially processed packet because it's skb->len dropped to zero, we need to decrement qlen because we are dropping out of the top-level loop so it will do the decrement for us. Spotted by Herbert Xu. Signed-off-by: -

The qlen should continue to decrement, even if we pop partially processed SKBs back onto the receive queue. Signed-off-by: -

Let's recap the problem. The current asynchronous netlink kernel message processing is vulnerable to these attacks: 1) Hit and run: Attacker sends one or more messages and then exits before they're processed. This may confuse/disable the next netlink user that gets the netlink address of the attacker since it may receive the responses to the attacker's messages. Proposed solutions: a) Synchronous processing. b) Stream mode socket. c) Restrict/prohibit binding. 2) Starvation: Because various netlink rcv functions were written to not return until all messages have been processed on a socket, it is possible for these functions to execute for an arbitrarily long period of time. If this is successfully exploited it could also be used to hold rtnl forever. Proposed solutions: a) Synchronous processing. b) Stream mode socket. Firstly let's cross off solution c). It only solves the first problem and it has user-visible impacts. In particular, it'll break user space applications that expect to bind or communicate with specific netlink addresses (pid's). So we're left with a choice of synchronous processing versus SOCK_STREAM for netlink. For the moment I'm sticking with the synchronous approach as suggested by Alexey since it's simpler and I'd rather spend my time working on other things. However, it does have a number of deficiencies compared to the stream mode solution: 1) User-space to user-space netlink communication is still vulnerable. 2) Inefficient use of resources. This is especially true for rtnetlink since the lock is shared with other users such as networking drivers. The latter could hold the rtnl while communicating with hardware which causes the rtnetlink user to wait when it could be doing other things. 3) It is still possible to DoS all netlink users by flooding the kernel netlink receive queue. The attacker simply fills the receive socket with a single netlink message that fills up the entire queue. The attacker then continues to call sendmsg with the same message in a loop. Point 3) can be countered by retransmissions in user-space code, however it is pretty messy. In light of these problems (in particular, point 3), we should implement stream mode netlink at some point. In the mean time, here is a patch that implements synchronous processing. Signed-off-by:

Here is a little optimisation for the cb_lock used by netlink_dump. While fixing that race earlier, I noticed that the reference count held by cb_lock is completely useless. The reason is that in order to obtain the protection of the reference count, you have to take the cb_lock. But the only way to take the cb_lock is through dereferencing the socket. That is, you must already possess a reference count on the socket before you can take advantage of the reference count held by cb_lock. As a corollary, we can remve the reference count held by the cb_lock. Signed-off-by:

kfree(0) is perfectly valid, checking pointers for NULL before calling kfree() on them is redundant. The patch below cleans away a few such redundant checks (and while I was around some of those bits I couldn't stop myself from making a few tiny whitespace changes as well). Signed-off-by:

Converts rtm_min and rtm_max arrays to use c99 designated initializers for easier insertion of new message families. RTM_GETMULTICAST and RTM_GETANYCAST did not have the minimal message size specified which means that the netlink message was parsed for routing attributes starting from the header. Adds the proper minimal message sizes for these messages (netlink header + common rtnetlink header) to fix this issue. Signed-off-by:

Thomas Graf authored
RTM_MAX is currently set to the maximum reserverd message type plus one thus being the cause of two bugs for new types being assigned a) given the new family registers only the NEW command in its reserved block the array size for per family entries is calculated one entry short and b) given the new family registers all commands RTM_MAX would point to the first entry of the block following this one and the rtnetlink receive path would accept a message type for a nonexisting family. This patch changes RTM_MAX to point to the maximum valid message type by aligning it to the start of the next block and subtracting one. Signed-off-by:

I made a mistake in my last patch to the raw socket checksum code. I used the value of inet->cork.length as the length of the payload. While this works with normal packets, it breaks down when IPsec is present since the cork length includes the extension header length. So here is a patch to fix the length calculations.
