2012-11-18net: Don't export sysctls to unprivileged usersEric W. Biederman
In preparation for supporting the creation of network namespaces by unprivileged users, modify all of the per net sysctl exports and refuse to allow them to unprivileged users. This makes it safe for unprivileged users in general to access per net sysctls, and allows sysctls to be exported to unprivileged users on an individual basis as they are deemed safe.

2012-11-18sysctl: Pass useful parameters to sysctl permissionsEric W. Biederman

With these changes it becomes possible to write a version of net_sysctl_permission that takes into account the network namespace of the sysctl table, an important feature in extending the user namespace.

2012-11-18userns: make each net (net_ns) belong to a user_nsEric W. Biederman
The user namespace which creates a new network namespace owns that namespace and all resources created in it. This way we can target capability checks for privileged operations against network resources to the user_ns which created the network namespace in which the resource lives. Privilege to the user namespace which owns the network namespace, or any parent user namespace thereof, provides the same privilege to the network resource.

The copy of copy_net_ns used when the network stack is not built is broken as it does not return -EINVAL when attempting to create a new network namespace. We don't even have a previous network namespace. Since we need a copy of copy_net_ns in net/net_namespace.h that is available when the networking stack is not built at all move the correct version of copy_net_ns from net_namespace.c into net_namespace.h Leaving us with just 2 versions of copy_net_ns.

This includes a pull of the Bluetooth tree. Gustavo says: "A few important fixes to go into 3.7. There is a new hw support by Marcos Chaparro. Johan added a memory leak fix and hci device index list fix. Also Marcel fixed a race condition in the device set up that was prevent the bt monitor to work properly. Last, Paulo Sérgio added a fix to the error status when pairing for LE fails. This was prevent userspace to work to handle the failure properly." Regarding the mac80211 pull, Johannes says: "I have a locking fix for some SKB queues, a variable initialization to avoid crashes in a certain failure case, another free_txskb fix from Felix and another fix from him to avoid calling a stopped driver, a fix for a (very unlikely) memory leak and a fix to not send null data packets when resuming while not associated." Regarding the iwlwifi pull, Johannes says: "Two more fixes for iwlwifi ... one to use ieee80211_free_txskb(), and one to check DMA mapping errors, please pull."

2012-11-16Merge tag 'batman-adv-fix-for-davem' of git://git.open-mesh.org/linux-mergeDavid S. Miller
Included fixes are: - update the client entry status flags when using the "early client detection". This makes the Distributed AP isolation correctly work; - transfer the client entry status flags when recovering the translation table from another node. This makes the Distributed AP isolation correctly work; - prevent the "early client detection mechanism" to add clients belonging to other backbone nodes in the same LAN. This breaks connectivity when using this mechanism together with the Bridge Loop Avoidance - process broadcast packets with the Bridge Loop Avoidance before any other component. BLA can possibly drop the packets based on the source address. This makes the "early client detection mechanism" correctly work when used with BLA. Signed-off-by: David S.

2012-11-16batman-adv: process broadcast packets in BLA earlierAntonio Quartulli
The logic in the BLA mechanism may decide to drop broadcast packets because the node may still be in the setup phase. For this reason, further broadcast processing like the early client detection mechanism must be done only after the BLA check. This patches moves the invocation to BLA before any other broadcast processing.

This patch fixes code according with this sentence. Here are three points, which were not done in the initial patch: 1. A tcp send head should not be changed 2. Initialize TSO state of a skb 3.

2012-11-15sctp: fix /proc/net/sctp/ memory leakTommi Rantala
Commit 13d782f ("sctp: Make the proc files per network namespace.") changed the /proc/net/sctp/ struct file_operations opener functions to use single_open_net() and seq_open_net(). Avoid leaking memory by using single_release_net() and seq_release_net() as the release functions. Discovered with Trinity (the syscall fuzzer).

2012-11-15ip6tnl: fix sparse warnings in ip6_tnl_netlink_parms()Nicolas Dichtel
This change fixes a sparse warning triggered by casting the flowinfo from netlink messages in an u32 instead of be32. This change corrects that in order to resolve the sparse warning.

2012-11-15sit: fix sparse warningsNicolas Dichtel
This change fixes several sparse warnings about endianness problem. The wrong nla_*() functions were used. It also fix a sparse warning about a flag test (field i_flags). This field is used in this file like a local flag only, so it is more an u16 (gre uses it as a be16). This sparse warning was already there before the patch that add netlink management, the code has just been moved.
