* batman-adv: Correct rcu refcounting for orig_nodeMarek Lindner2011-03-059-36/+49
| | | | | | | | | | | It might be possible that 2 threads access the same data in the same rcu grace period. The first thread calls call_rcu() to decrement the refcount and free the data while the second thread increases the refcount to use the data. To avoid this race condition all refcount operations have to be atomic. Reported-by: Sven Eckelmann <sven@narfation.org> Signed-off-by: Marek Lindner <lindner_marek@yahoo.de>

* batman-adv: Fix possible buffer overflow in softif neigh list outputLinus Lüssing2011-03-051-21/+1
| | | | | | | | | | | | | | | | | | When printing the soft interface table the number of entries in the softif neigh list are first being counted and a fitting buffer allocated. After that the softif neigh list gets locked again and the buffer printed - which has the following two issues: For one thing, the softif neigh list might have grown when reacquiring the rcu lock, which results in writing outside of the allocated buffer. Furthermore 31 Bytes are not enough for printing an entry with a vid of more than 2 digits. The manual buffering is unnecessary, we can safely print to the seq directly during the rcu_read_lock().

| | | | | | | | | When unicast_send_skb() is increasing the orig_node's refcount another thread might have been freeing this orig_node already.

Otherwise we might end up using a curr_gw pointer pointing to already freed memory.

* batman-adv: make broadcast seqno operations atomicMarek Lindner2011-03-053-22/+37
| | | | | | | | | | | | Batman-adv could receive several payload broadcasts at the same time that would trigger access to the broadcast seqno sliding window to determine whether this is a new broadcast or not. If these incoming broadcasts are accessing the sliding window simultaneously it could be left in an inconsistent state. Therefore it is necessary to make sure this access is atomic.

* batman-adv: Use successive sequence numbers for fragmentsSven Eckelmann2011-02-111-4/+4
| | | | | | | | | | | | | | | | | The two fragments of an unicast packet must have successive sequence numbers to allow the receiver side to detect matching fragments and merge them again. The current implementation doesn't provide that property because a sequence of two atomic_inc_return may be interleaved with another sequence which also changes the variable. The access to the fragment sequence number pool has either to be protected by correct locking or it has to reserve two sequence numbers in a single fetch. The latter one can easily be done by increasing the value of the last used sequence number by 2 in a single step. The generated window of two currently unused sequence numbers can now be scattered across the two fragments.

* batman-adv: Calculate correct size for merged packetsSven Eckelmann2011-01-314-3/+31
| | | | | | | | | | | | | | | | | | | | The routing algorithm must be able to decide if a fragment can be merged with the missing part and still be passed to a forwarding interface. The fragments can only differ by one byte in case that the original payload had an uneven length. In that situation the sender has to inform all possible receivers that the tail is one byte longer using the flag UNI_FRAG_LARGETAIL. The combination of UNI_FRAG_LARGETAIL and UNI_FRAG_HEAD flag makes it possible to calculate the correct length for even and uneven sized payloads. The original formula missed to add the unicast header at all and forgot to remove the fragment header of the second fragment. This made the results highly unreliable and only useful for machines with large differences between the configured MTUs.

* batman-adv: Create roughly equal sized fragmentsSven Eckelmann2011-01-311-2/+3
| | | | | | | | | | | | | | | | | | | | | The routing algorithm must know how large two fragments are to be able to decide that it is safe to merge them or if it should resubmit without waiting for the second part. When these two fragments have a too different size, it is not possible to guess right in every situation. The user could easily configure the MTU of the attached cards so that one fragment is forwarded and the other one is added to the fragments table to wait for the missing part. For even sized packets, it is possible to split it so that the resulting packages are equal sized by ignoring the old non-fragment header at the beginning of the original packet. This still creates different sized fragments for uneven sized packets.

* kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERTDavid Rientjes2011-01-203-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a network namespace is created (via CLONE_NEWNET), the loopback interface is automatically added to the new namespace, triggering a printk in ipv6_add_dev() if CONFIG_IPV6_PRIVACY is set. This is problematic for applications which use CLONE_NEWNET as part of a sandbox, like Chromium's suid sandbox or recent versions of vsftpd. On a busy machine, it can lead to thousands of useless "lo: Disabled Privacy Extensions" messages appearing in dmesg. It's easy enough to check the status of privacy extensions via the use_tempaddr sysctl, so just removing the printk seems like the most sensible solution.

If this happens we'll pass a NULL pointer on to skb_split() which in turn hands it to skb_split_inside_header() from where it gets passed to skb_put() that lets skb_tail_pointer() play with it and that function dereferences it. And thus the bat dies. While I was at it I also moved the call to dev_alloc_skb() above the assignment to 'unicast_packet' since there's no reason to do that assignment if the memory allocation fails.
