2011-08-06net: Compute protocol sequence numbers and fragment IDs using MD5.David S. Miller11-8/+195
Computers have become a lot faster since we compromised on the partial MD4 hash which we use currently for performance reasons. MD5 is a much safer choice, and is inline with both RFC1948 and other ISS generators (OpenBSD, Solaris, etc.) Furthermore, only having 24-bits of the sequence number be truly unpredictable is a very serious limitation. So the periodic regeneration and 8-bit counter have been removed. We compute and use a full 32-bit sequence number. For ipv6, DCCP was found to use a 32-bit truncated initial sequence number (it needs 43-bits) and that is fixed here as well.

2011-08-05ipv6: check for IPv4 mapped addresses when connecting IPv6 socketsMax Matveev1-2/+9
When support for binding to 'mapped INADDR_ANY (::ffff.0.0.0.0)' was added in 0f8d3c7ac3693d7b6c731bf2159273a59bf70e12 the rest of the code wasn't told so now it's possible to bind IPv6 datagram socket to ::ffff.0.0.0.0, connect it to another IPv4 address and it will all work except for getsockhame() which does not return the local address as expected. To give getsockname() something to work with check for 'mapped INADDR_ANY' when connecting and update the in-core source addresses appropriately.

2011-08-05net: Fix security_socket_sendmsg() bypass problem.Tetsuo Handa1-9/+34
The sendmmsg() introduced by commit 228e548e "net: Add sendmmsg socket system call" is capable of sending to multiple different destination addresses. SMACK is using destination's address for checking sendmsg() permission. However, security_socket_sendmsg() is called for only once even if multiple different destination addresses are passed to sendmmsg(). Therefore, we need to call security_socket_sendmsg() for each destination address rather than only the first destination address. Since calling security_socket_sendmsg() every time when only single destination address was passed to sendmmsg() is a waste of time, omit calling security_socket_sendmsg() unless destination address of previous datagram and that of current datagram differs.

2011-08-05net: Cap number of elements for sendmmsgAnton Blanchard1-0/+3
To limit the amount of time we can spend in sendmmsg, cap the number of elements to UIO_MAXIOV (currently 1024). For error handling an application using sendmmsg needs to retry at the first unsent message, so capping is simpler and requires less application logic than returning EINVAL.

2011-08-05net: sendmmsg should only return an error if no messages were sentAnton Blanchard1-24/+3
sendmmsg uses a similar error return strategy as recvmmsg but it turns out to be a confusing way to communicate errors. The current code stores the error code away and returns it on the next sendmmsg call. This means a call with completely valid arguments could get an error from a previous call. Change things so we only return an error if no datagrams could be sent. If less than the requested number of messages were sent, the application must retry starting at the first failed one and if the problem is persistent the error will be returned. This matches the behaviour of other syscalls like read/write - it is not an error if less than the requested number of elements are sent.

2011-08-03net: fix NULL dereferences in check_peer_redir()Eric Dumazet6-22/+54
Gergely Kalman reported crashes in check_peer_redir(). It appears commit f39925dbde778 (ipv4: Cache learned redirect information in inetpeer.) added a race, leading to possible NULL ptr dereference. Since we can now change dst neighbour, we should make sure a reader can safely use a neighbour. Add RCU protection to dst neighbour, and make sure check_peer_redir() can be called safely by different cpus in parallel. As neighbours are already freed after one RCU grace period, this patch should not add typical RCU penalty (cache cold effects) Many thanks to Gergely for providing a pretty report pointing to the bug.

After the last patch, We are left in a state in which only drivers calling ether_setup have IFF_TX_SKB_SHARING set (we assume that drivers touching real hardware call ether_setup for their net_devices and don't hold any state in their skbs. There are a handful of drivers that violate this assumption of course, and need to be fixed up.

Pktgen attempts to transmit shared skbs to net devices, which can't be used by some drivers as they keep state information in skbs. This patch adds a flag marking drivers as being able to handle shared skbs in their tx path. Drivers are defaulted to being unable to do so, but calling ether_setup enables this flag, as 90% of the drivers calling ether_setup touch real hardware and can handle shared skbs. A subsequent patch will audit drivers to ensure that the flag is set properly Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Reported-by: Jiri Pirko <jpirko@redhat.com> CC: Robert Olsson <robert.olsson@its.uu.se> CC: Eric Dumazet <eric.dumazet@gmail.com> CC: Alexey Dobriyan <adobriyan@gmail.com> CC: David S.
