dlm: check the write size from user

2013-02-04T21:31:22Z

Return EINVAL from write if the size is larger than allowed. Do this before allocating kernel memory for the bogus size, which could lead to OOM. Reported-by: Sasha Levin Tested-by: Jana Saout Signed-off-by: David Teigland

dlm: fix lvb invalidation conditions

2012-11-16T17:20:42Z

When a node is removed that held a PW/EX lock, the existing master node should invalidate the lvb on the resource due to the purged lock. Previously, the existing master node was invalidating the lvb if it found only NL/CR locks on the resource during recovery for the removed node. This could lead to cases where it invalidated the lvb and shouldn't have, or cases where it should have invalidated and didn't. When recovery selects a *new* master node for a resource, and that new master finds only NL/CR locks on the resource after lock recovery, it should invalidate the lvb. This case was handled correctly (but was incorrectly applied to the existing master case also.) When a process exits while holding a PW/EX lock, the lvb on the resource should be invalidated. This was not happening. The lvb contents and VALNOTVALID flag should be recovered before granting locks in recovery so that the recovered lvb state is provided in the callback. The lvb was being recovered after the lock was granted. Signed-off-by: David Teigland

fs/dlm: remove CONFIG_EXPERIMENTAL

2012-11-01T20:27:24Z

This config item has not carried much meaning for a while now and is almost always enabled by default. As agreed during the Linux kernel summit, remove it. CC: Christine Caulfield Signed-off-by: Kees Cook Signed-off-by: David Teigland

dlm: remove unused variable in *dlm_lowcomms_get_buffer()

2012-11-01T20:27:13Z

The variable users is initialized but never used otherwise, so remove the unused variable. dpatch engine is used to auto generate this patch. (https://github.com/weiyj/dpatch) Signed-off-by: Wei Yongjun Signed-off-by: David Teigland

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.

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.

dlm: check the maximum size of a request from user

2012-09-10T14:50:27Z

device_write only checks whether the request size is big enough, but it doesn't check if the size is too big. At that point, it also tries to allocate as much memory as the user has requested even if it's too much. This can lead to OOM killer kicking in, or memory corruption if (count + 1) overflows.

dlm: convert add_sock routine return value type to void

dlm: remove redundant variable assignments

2012-08-10T14:10:10Z

Once the tcp_create_listen_sock() is returned successfully, we will invoke add_sock() immediately. In add_sock(), the 'con' variable is assigned to 'sk_user_data', meanwhile, the 'sock' is also set to 'con->sock'. So it's unnecessary to do the same thing in tcp_create_listen_sock().
