2016-03-31orangefs: don't put readdir slot twiceMartin Brandenburg
This was quite an oversight. After a readdir, the module could not be unloaded, the number of slots is wrong, and memory near the slot bitmap is possibly corrupt. Oops. Signed-off-by: Martin Brandenburg <martin@omnibond.com>
2016-03-31Merge branch '10GbE' of ↵David S. Miller
git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-queue Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2016-03-29 This series contains fixes to ixgbe and ixgbevf. Tushar fixes an issue which was introduced with an earlier commit, where hardware register RAR0 default MAC address does not get set properly. Alex fixes two issues, first being the VXLAN port number should be stored in network order instead of in host order. The second fix corrects the ATR code to handle IPv6 extension headers. The issue was ATR code was assuming that it would be able to use tcp_hdr for every TCP frame that came through, but that is not the case, which resulted in bad filters being setup. Mark fixes a use of usleep_range() to udelay() in the case where a lock is being held. Stefan fixes the offline self tests where ndo_stop() should be used instead of ndo_close(), which causes IFF_UP to be cleared and interface routes get removed. Emil fixes the error case where we need to return an error when a MAC address change is rejected by the PF. This helps prevent the user from modifying the MAC address when the operation is not permitted. Sridhar provides three fixes for ixgbe, all dealing with traffic class offload handling. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2016-03-31locking/lockdep: Print chain_key collision informationAlfredo Alvarez Fernandez
A sequence of pairs [class_idx -> corresponding chain_key iteration] is printed for both the current held_lock chain and the cached chain. That exposes the two different class_idx sequences that led to that particular hash value. This helps with debugging hash chain collision reports.

2016-03-31parisc: Fix and enable seccomp filter supportHelge Deller
The seccomp filter support requires careful handling of task registers. This includes reloading of the return value (%r28) and proper syscall exit if secure_computing() returned -1. Additionally we need to sign-extend the syscall number from signed 32bit to signed 64bit in do_syscall_trace_enter() since the ptrace interface only allows storing 32bit values in compat mode.

2016-03-31drm/imx: ipuv3-plane: Configure DMFC wait4eot bit after slots are determinedLiu Ying
Just as the function ipu_dmfc_config_wait4eot() tells, the DMFC wait4eot bit depends on the number of DMFC slots to be used, so it should be called after the slots are determined in the function ipu_dmfc_alloc_bandwidth(). Based on tests, this patch may eliminate display distortion issue on overlay plane with small resolutions. To reproduce the issue, we may run this drm modetest case - 'modetest -P 19:64x64'.

2016-03-31drm/imx: dw_hdmi: Don't call platform_set_drvdata()Douglas Anderson
The IMX dw_hdmi driver just called platform_set_drvdata() to get your hopes up that maybe, somehow, you'd be able to retrieve the 'struct imx_hdmi' from a pointer to the 'struct device'. You can't. When we call dw_hdmi_bind() the main driver calls dev_set_drvdata(), which clobbers our setting. Let's just remove the platform_set_drvdata() to avoid dashing people's hopes.

2016-03-31arm64: KVM: Register CPU notifiers when the kernel runs at HYPJames Morse
When the kernel is running at EL2, it doesn't need init_hyp_mode() to configure page tables for HYP. This function also registers the CPU hotplug and lower power notifiers that cause HYP to be re-initialised after the CPU has been reset. To avoid losing the register state that controls stage2 translation, move the registering of these notifiers into init_subsystems(), and add a is_kernel_in_hyp_mode() path to each callback.

Make the 2 byte padding in struct bpf_tunnel_key between tunnel_ttl and tunnel_label members explicit. No issue has been observed, and gcc/llvm does padding for the old struct already, where tunnel_label was not yet present, so the current code works, but since it's part of uapi, make sure we don't introduce holes in structs. Therefore, add tunnel_ext that we can use generically in future (f.e. to flag OAM messages for backends, etc). Also add the offset to the compat tests to be sure should some compilers not padd the tail of the old version of bpf_tunnel_key.

2016-03-30perf hists: Fix determination of a callchain node's childlessnessAndres Freund
The 4b3a3212233a ("perf hists browser: Support flat callchains") commit over-aggressively tried to optimize callchain_node__init_have_children(). That lead to --tui mode not allowing to expand call chain elements if a call chain element had only one parent. That's why --inverted callgraphs looked halfway sane, but plain ones didn't. Revert that individual optimization, it wasn't really related to the rest of the commit.

2016-03-30team: team should sync the port's uc/mc addrs when add a portXin Long
There is an issue when we use mavtap over team: When we replug nic links from team0, the real nics's mc list will not include the maddr for macvtap any more. then we can't receive pkts to macvtap device, as they are filterred by mc list of nic. In Bonding Driver, it syncs the uc/mc addrs in bond_enslave(). We will fix this issue on team by adding the port's uc/mc addrs sync in team_port_add.

2016-03-30f2fs: retrieve IO write stat from the right placeShuoran Liu
In the following patch, f2fs: split journal cache from curseg cache journal cache is split from curseg cache. So IO write statistics should be retrived from journal cache but not curseg->sum_blk. Otherwise, it will get 0, and the stat is lost. Signed-off-by: Shuoran Liu <liushuoran@huawei.com> Reviewed-by: Chao Yu <chao@kernel.org> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
2016-03-30f2fs crypto: fix corrupted symlink in encrypted caseJaegeuk Kim
In the encrypted symlink case, we should check its corrupted symname after decrypting it. Otherwise, we can report -ENOENT incorrectly, if encrypted symname starts with '\0'. Cc: stable 4.5+ <stable@vger.kernel.org> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
2016-03-30arm64: kvm: 4.6-rc1: Fix VTCR_EL2 VS settingSuzuki K Poulose
When we detect support for 16bit VMID in ID_AA64MMFR1, we set the VTCR_EL2_VS field to 1 to make use of 16bit vmids. But, with commit 3a3604bc5eb4 ("arm64: KVM: Switch to C-based stage2 init") this is broken and we corrupt VTCR_EL2:T0SZ instead of updating the VS field. VTCR_EL2_VS was actually defined to the field shift (19) and not the real value for VS. This patch fixes the issue.

2016-03-30gro: Allow tunnel stacking in the case of FOU/GUEAlexander Duyck
This patch should fix the issues seen with a recent fix to prevent tunnel-in-tunnel frames from being generated with GRO. The fix itself is correct for now as long as we do not add any devices that support NETIF_F_GSO_GRE_CSUM. When such a device is added it could have the potential to mess things up due to the fact that the outer transport header points to the outer UDP header and not the GRE header as would be expected.
