netlabel: fix build problems when CONFIG_IPV6=n

2013-03-08T16:33:51Z

My last patch to solve a problem where the static/fallback labels were not fully displayed resulted in build problems when IPv6 was disabled. This patch resolves the IPv6 build problems; sorry for the screw-up. Please queue for -stable or simply merge with the previous patch.

netlabel: correctly list all the static label mappings

2013-03-07T21:20:23Z

When we have a large number of static label mappings that spill across the netlink message boundary we fail to properly save our state in the netlink_callback struct which causes us to repeat the same listings. This patch fixes this problem by saving the state correctly between calls to the NetLabel static label netlink "dumpit" routines. Signed-off-by: Paul Moore Signed-off-by: David S. Miller

Pull networking changes from David Miller: 1) GRE now works over ipv6, from Dmitry Kozlov. 2) Make SCTP more network namespace aware, from Eric Biederman. 3) TEAM driver now works with non-ethernet devices, from Jiri Pirko. 4) Make openvswitch network namespace aware, from Pravin B Shelar. 5) IPV6 NAT implementation, from Patrick McHardy. 6) Server side support for TCP Fast Open, from Jerry Chu and others. 7) Packet BPF filter supports MOD and XOR, from Eric Dumazet and Daniel Borkmann. 8) Increate the loopback default MTU to 64K, from Eric Dumazet. 9) Use a per-task rather than per-socket page fragment allocator for outgoing networking traffic. This benefits processes that have very many mostly idle sockets, which is quite common. From Eric Dumazet. 10) Use up to 32K for page fragment allocations, with fallbacks to smaller sizes when higher order page allocations fail. Benefits are a) less segments for driver to process b) less calls to page allocator c) less waste of space. From Eric Dumazet. 11) Allow GRO to be used on GRE tunnels, from Eric Dumazet. 12) VXLAN device driver, one way to handle VLAN issues such as the limitation of 4096 VLAN IDs yet still have some level of isolation. From Stephen Hemminger. 13) As usual there is a large boatload of driver changes, with the scale perhaps tilted towards the wireless side this time around. Fix up various fairly trivial conflicts, mostly caused by the user namespace changes. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1012 commits) hyperv: Add buffer for extended info after the RNDIS response message. hyperv: Report actual status in receive completion packet hyperv: Remove extra allocated space for recv_pkt_list elements hyperv: Fix page buffer handling in rndis_filter_send_request() hyperv: Fix the missing return value in rndis_filter_set_packet_filter() hyperv: Fix the max_xfer_size in RNDIS initialization vxlan: put UDP socket in correct namespace vxlan: Depend on CONFIG_INET sfc: Fix the reported priorities of different filter types sfc: Remove EFX_FILTER_FLAG_RX_OVERRIDE_IP sfc: Fix loopback self-test with separate_tx_channels=1 sfc: Fix MCDI structure field lookup sfc: Add parentheses around use of bitfield macro arguments sfc: Fix null function pointer in efx_sriov_channel_type vxlan: virtual extensible lan igmp: export symbol ip_mc_leave_group netlink: add attributes to fdb interface tg3: unconditionally select HWMON support when tg3 is enabled.

userns: Convert the audit loginuid to be a kuid

2012-09-18T01:08:54Z

Always store audit loginuids in type kuid_t. Print loginuids by converting them into uids in the appropriate user namespace, and then printing the resulting uid. Modify audit_get_loginuid to return a kuid_t. Modify audit_set_loginuid to take a kuid_t. Modify /proc//loginuid on read to convert the loginuid into the user namespace of the opener of the file. Modify /proc//loginud on write to convert the loginuid rom the user namespace of the opener of the file. Cc: Al Viro Cc: Eric Paris Cc: Paul Moore ? Cc: David Miller Signed-off-by: Eric W. Biederman

netlink: Rename pid to portid to avoid confusion

2012-09-10T19:30:41Z

It is a frequent mistake to confuse the netlink port identifier with a process identifier. Try to reduce this confusion by renaming fields that hold port identifiers portid instead of pid. I have carefully avoided changing the structures exported to userspace to avoid changing the userspace API. I have successfully built an allyesconfig kernel with this change. Signed-off-by: "Eric W.

netlabel: use GFP flags from caller instead of GFP_ATOMIC

2012-03-22T23:29:57Z

This function takes a GFP flags as a parameter, but they are never used. We don't take a lock in this function so there is no reason to prefer GFP_ATOMIC over the caller's GFP flags. There is only one caller, cipso_v4_map_cat_rng_ntoh(), and it passes GFP_ATOMIC as the GFP flags so this doesn't change how the code works. It's just a cleanup.

net: reintroduce missing rcu_assign_pointer() calls

2012-01-12T20:26:56Z

commit a9b3cd7f32 (rcu: convert uses of rcu_assign_pointer(x, NULL) to RCU_INIT_POINTER) did a lot of incorrect changes, since it did a complete conversion of rcu_assign_pointer(x, y) to RCU_INIT_POINTER(x, y). We miss needed barriers, even on x86, when y is not NULL. Signed-off-by: Eric Dumazet CC: Stephen Hemminger CC: Paul E. McKenney Signed-off-by: David S. Miller

netlabel: Fix build problems when IPv6 is not enabled

2011-11-29T21:48:52Z

A recent fix to the the NetLabel code caused build problem with configurations that did not have IPv6 enabled; see below: netlabel_kapi.c: In function 'netlbl_cfg_unlbl_map_add': netlabel_kapi.c:165:4: error: implicit declaration of function 'netlbl_af6list_add' This patch fixes this problem by making the IPv6 specific code conditional on the IPv6 configuration flags as we done in the rest of NetLabel and the network stack as a whole. We have to move some variable declarations around as a result so things may not be quite as pretty, but at least it builds cleanly now. Some additional IPv6 conditionals were added to the NetLabel code as well for the sake of consistency.
