[ Upstream commit 530aa2d0 ] The current behaviour of the sh_eth driver is not to use the RNC bit for the receive ring. This means that every packet recieved is not only generating an IRQ but it also stops the receive ring DMA as well until the driver re-enables it after unloading the packet. This means that a number of the following errors are generated due to the receive packet FIFO overflowing due to nowhere to put packets: net eth0: Receive FIFO Overflow Since feedback from Yoshihiro Shimoda shows that every supported LSI for this driver should have the bit enabled it seems the best way is to remove the RMCR default value from the per-system data and just write it when initialising the RMCR value. This is discussed in the message (http://www.spinics.net/lists/netdev/msg284912.html). I have tested the 0x00000001 configuration with NFS root filesystem and the driver has not failed yet. There are further test reports from Sergei Shtylov and others for both the R8A7790 and R8A7791. There is also feedback fron Cao Minh Hiep[1] which reports the same issue in (http://comments.gmane.org/gmane.linux.network/316285) showing this fixes issues with losing UDP datagrams under iperf.

[ Upstream commit 0cfa5c07 ] This bug is discovered by an recent F-RTO issue on tcpm list https://www.ietf.org/mail-archive/web/tcpm/current/msg08794.html The bug is that currently F-RTO does not use DSACK to undo cwnd in certain cases: upon receiving an ACK after the RTO retransmission in F-RTO, and the ACK has DSACK indicating the retransmission is spurious, the sender only calls tcp_try_undo_loss() if some never retransmisted data is sacked (FLAG_ORIG_DATA_SACKED). The correct behavior is to unconditionally call tcp_try_undo_loss so the DSACK information is used properly to undo the cwnd reduction. Signed-off-by:

[ Upstream commit 9d0d68fa ] Now it is not possible to set mtu to team device which has a port enslaved to it. The reason is that when team_change_mtu() calls dev_set_mtu() for port device, notificator for NETDEV_PRECHANGEMTU event is called and team_device_event() returns NOTIFY_BAD forbidding the change. So fix this by returning NOTIFY_DONE here in case team is changing mtu in team_change_mtu(). Introduced-by: 3d249d4c "net: introduce ethernet teaming device" Signed-off-by:

[ Upstream commit 39c36094 ] I noticed we were sending wrong IPv4 ID in TCP flows when MTU discovery is disabled. Note how GSO/TSO packets do not have monotonically incrementing ID. 06:37:41.575531 IP (id 14227, proto: TCP (6), length: 4396) 06:37:41.575534 IP (id 14272, proto: TCP (6), length: 65212) 06:37:41.575544 IP (id 14312, proto: TCP (6), length: 57972) 06:37:41.575678 IP (id 14317, proto: TCP (6), length: 7292) 06:37:41.575683 IP (id 14361, proto: TCP (6), length: 63764) It appears I introduced this bug in linux-3.1. inet_getid() must return the old value of peer->ip_id_count, not the new one. Lets revert this part, and remove the prevention of a null identification field in IPv6 Fragment Extension Header, which is dubious and not even done properly.

[ Upstream commit e0d7968a ] br_handle_local_finish() is allowing us to insert an FDB entry with disallowed vlan. For example, when port 1 and 2 are communicating in vlan 10, and even if vlan 10 is disallowed on port 3, port 3 can interfere with their communication by spoofed src mac address with vlan id 10. Note: Even if it is judged that a frame should not be learned, it should not be dropped because it is destined for not forwarding layer but higher layer. See IEEE 802.1Q-2011 8.13.10. Signed-off-by:

[ Upstream commit 2d7a85f4 ] It was possible to get a setuid root or setcap executable to write to it's stdout or stderr (which has been set made a netlink socket) and inadvertently reconfigure the networking stack. To prevent this we check that both the creator of the socket and the currentl applications has permission to reconfigure the network stack. Unfortunately this breaks Zebra which always uses sendto/sendmsg and creates it's socket without any privileges. To keep Zebra working don't bother checking if the creator of the socket has privilege when a destination address is specified. Instead rely exclusively on the privileges of the sender of the socket. Note from Andy: This is exactly Eric's code except for some comment clarifications and formatting fixes. Neither I nor, I think, anyone else is thrilled with this approach, but I'm hesitant to wait on a better fix since 3.15 is almost here. Note to stable maintainers: This is a mess. An earlier series of patches in 3.15 fix a rather serious security issue (CVE-2014-0181), but they did so in a way that breaks Zebra. The offending series includes: commit aa4cf945 Author: Eric W. Biederman <ebiederm@xmission.com> Date: Wed Apr 23 14:28:03 2014 -0700 net: Add variants of capable for use on netlink messages If a given kernel version is missing that series of fixes, it's probably worth backporting it and this patch. if that series is present, then this fix is critical if you care about Zebra.

[ Upstream commit 90f62cf3 ] It is possible by passing a netlink socket to a more privileged executable and then to fool that executable into writing to the socket data that happens to be valid netlink message to do something that privileged executable did not intend to do. To keep this from happening replace bare capable and ns_capable calls with netlink_capable, netlink_net_calls and netlink_ns_capable calls. Which act the same as the previous calls except they verify that the opener of the socket had the desired permissions as well. Reported-by:

The 'guilty' commit changed the order of cleanup code so that nsproxy->mnt_ns was not already available for Apparmor. Discussion about the issue with Al Viro and Eric W. Biederman suggested that kernel_read() is too high-level for IMA. Another issue, except security checking, that was identified is mandatory locking. kernel_read honors it as well and it might prevent IMA from calculating necessary hash. It was suggested to use simplified version of the function without security and locking checks. This patch introduces special version ima_kernel_read(), which skips security and mandatory locking checking. It prevents the kernel oops to happen. Signed-off-by:

commit 2fe121e1 upstream. The rtc user must wait at least 1 sec between each time/calandar update (see atmel's datasheet chapter "Updating Time/Calendar"). Use the 1Hz interrupt to update the at91_rtc_upd_rdy flag and wait for the at91_rtc_wait_upd_rdy event if the rtc is not ready. This patch fixes a deadlock in an uninterruptible wait when the RTC is updated more than once every second. AFAICT the bug is here from the beginning, but I think we should at least backport this fix to 3.10 and the following longterm and stable releases. Signed-off-by:

commit f9b2a735 upstream. Files are measured or appraised based on the IMA policy. When a file, in policy, is opened with the O_DIRECT flag, a deadlock occurs. The first attempt at resolving this lockdep temporarily removed the O_DIRECT flag and restored it, after calculating the hash. The second attempt introduced the O_DIRECT_HAVELOCK flag. Based on this flag, do_blockdev_direct_IO() would skip taking the i_mutex a second time. The third attempt, by Dmitry Kasatkin, resolves the i_mutex locking issue, by re-introducing the IMA mutex, but uncovered another problem. Reading a file with O_DIRECT flag set, writes directly to userspace pages. A second patch allocates a user-space like memory. This works for all IMA hooks, except ima_file_free(), which is called on __fput() to recalculate the file hash. Until this last issue is addressed, do not 'collect' the measurement for measuring, appraising, or auditing files opened with the O_DIRECT flag set. Based on policy, permit or deny file access. This patch defines a new IMA policy rule option named 'permit_directio'. Policy rules could be defined, based on LSM or other criteria, to permit specific applications to open files with the O_DIRECT flag set.

commit 40478455 upstream. In commit commit 6375b768 Author: Ville Syrjälä <ville.syrjala@linux.intel.com> Date: Mon Mar 3 11:33:36 2014 +0200 drm/i915: Reject >165MHz modes w/ DVI monitors the driver started to filter out display modes which exceed the single-link DVI 165Mz dotclock limits when the monitor doesn't report itself as being HDMI compliant. The intent was to filter out all EDID derived modes that require dual-link DVI to operate since we don't support dual-link. However the patch went a bit too far and also causes the driver to reject such modes even when specified by the user. Normally we don't check the sink limitations when setting a mode from the user. This allows the user to specify any mode whether the sink reports to support it or not. This can be useful since often the sinks support more modes than they report in the EDID. So relax the checks a bit, and apply the single-link DVI dotclock limit only when filtering the mode list, and ignore the limit when setting a user specified mode.

commit e7810c2d upstream. This patch allows READ_CAPACITY + SAI_READ_CAPACITY_16 opcode processing to occur while the associated ALUA group is in Standby access state. This is required to avoid host side LUN probe failures during the initial scan if an ALUA group has already implicitly changed into Standby access state. This addresses a bug reported by Chris + Philip using dm-multipath + ESX hosts configured with ALUA multipath. (Drop v3.15 specific set_ascq usage - nab) Reported-by:

commit 2363d196 upstream. This patch fixes a iser-target specific regression introduced in v3.15-rc6 with: commit 14f4b54f Author: Sagi Grimberg <sagig@mellanox.com> Date: Tue Apr 29 13:13:47 2014 +0300 Target/iscsi,iser: Avoid accepting transport connections during stop stage where the change to set iscsi_np->enabled = false within iscsit_clear_tpg_np_login_thread() meant that a iscsi_np with two iscsi_tpg_np exports would have it's parent iscsi_np set to a disabled state, even if other iscsi_tpg_np exports still existed. This patch changes iscsit_clear_tpg_np_login_thread() to only set iscsi_np->enabled = false when shutdown = true, and also changes iscsit_del_np() to set iscsi_np->enabled = true when iscsi_np->np_exports is non zero.

commit 14f4b54f upstream. When the target is in stop stage, iSER transport initiates RDMA disconnects. The iSER initiator may wish to establish a new connection over the still existing network portal. In this case iSER transport should not accept and resume new RDMA connections. In order to learn that, iscsi_np is added with enabled flag so the iSER transport can check when deciding weather to accept and resume a new connection request. The iscsi_np is enabled after successful transport setup, and disabled before iscsi_np login threads are cleaned up. Signed-off-by:
