* net: Fix use after free by removing length arg from sk_data_ready callbacks.David S. Miller2014-04-111-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Several spots in the kernel perform a sequence like: skb_queue_tail(&sk->s_receive_queue, skb); sk->sk_data_ready(sk, skb->len); But at the moment we place the SKB onto the socket receive queue it can be consumed and freed up. So this skb->len access is potentially to freed up memory. Furthermore, the skb->len can be modified by the consumer so it is possible that the value isn't accurate. And finally, no actual implementation of this callback actually uses the length argument. And since nobody actually cared about it's value, lots of call sites pass arbitrary values in such as '0' and even '1'. So just remove the length argument from the callback, that way there is no confusion whatsoever and all of these use-after-free cases get fixed as a side effect. Based upon a patch by Eric Dumazet and his suggestion to audit this issue tree-wide. Signed-off-by: David S. Miller <davem@davemloft.net>

From Fan Du. 2) Make xfrm migration namespace aware. From Fan Du. 3) Make the xfrm state and policy locks namespace aware. From Fan Du. 4) Remove ancient sleeping when the SA is in acquire state, we now queue packets to the policy instead. This replaces the sleeping code. 5) Remove FLOWI_FLAG_CAN_SLEEP. This was used to notify xfrm about the posibility to sleep. The sleeping code is gone, so remove it. 6) Check user specified spi for IPComp. Thr spi for IPcomp is only 16 bit wide, so check for a valid value. From Fan Du. 7) Export verify_userspi_info to check for valid user supplied spi ranges with pfkey and netlink. From Fan Du. 8) RFC3173 states that if the total size of a compressed payload and the IPComp header is not smaller than the size of the original payload, the IP datagram must be sent in the original non-compressed form. These packets are dropped by the inbound policy check because they are not transformed. Document the need to set 'level use' for IPcomp to receive such packets anyway. From Fan Du.

* hlist: drop the node parameter from iteratorsSasha Levin2013-02-282-14/+8

I'm not quite sure. Not only they don't really need it, it also prevents the iterator from looking exactly like the list iterator, which is unfortunate. Besides the semantic patch, there was some manual work required: - Fix up the actual hlist iterators in linux/list.h - Fix up the declaration of other iterators based on the hlist ones. - A very small amount of places were using the 'node' parameter, this was modified to use 'obj->member' instead. - Coccinelle didn't handle the hlist_for_each_entry_safe iterator properly, so those had to be fixed up manually.

* netlink: add netlink_kernel_cfg parameter to netlink_kernel_createPablo Neira Ayuso2012-06-301-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the following structure: struct netlink_kernel_cfg { unsigned int groups; void (*input)(struct sk_buff *skb); struct mutex *cb_mutex; }; That can be passed to netlink_kernel_create to set optional configurations for netlink kernel sockets. I've populated this structure by looking for NULL and zero parameters at the existing code. The remaining parameters that always need to be set are still left in the original interface. That includes optional parameters for the netlink socket creation. This allows easy extensibility of this interface in the future. This patch also adapts all callers to use this new interface.

* | net: Remove casts to same typeJoe Perches2012-06-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adding casts of objects to the same type is unnecessary and confusing for a human reader. For example, this cast: int y; int *p = (int *)&y; I used the coccinelle script below to find and remove these unnecessary casts. I manually removed the conversions this script produces of casts with __force and __user. @@ type T; T *p; @@ - (T *)p + p Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S.
