2015-10-14ACPICA: Tables: Fix FADT dependency regressionLv Zheng5-33/+10
Some logics actually relying on the existence of FADT, currently relies on the number of loaded tables. This false dependency can easily trigger regressions. One of them has been introduced by commit 8ec3f459073e (ACPICA: Tables: Fix global table list issues by removing fixed table). The commit changing the fixed table indexes results in the change of FADT table index, originally, it was 3 (thus the installed table count should be greater than 4), while currently it is 0 (and the installed table count may be 3). This patch fixes this regression by cleaning up the code. Lv Zheng.

2015-10-14Partially revert "clk: mvebu: Convert to clk_hw based provider APIs"Stephen Boyd1-1/+3
This partially reverts commit eca61c9ff2588e1df373e61078e1874976315839. Thomas reports that it causes regressions on Armada XP devices. This is because of_clk_get_parent_name() relies on the property 'clock-output-names' to resolve the name of a clock's parent, without trying to get the clock from the framework and call __clk_get_name(). Given that Armada XP devices don't have the 'clock-output-names' property, of_clk_get_parent_name() returns the name of the node which doesn't match the actual parent clock's name at all, causing CPU clocks to never link up with their parents.

2015-10-14KVM: x86: fix RSM into 64-bit protected modePaolo Bonzini1-3/+7
In order to get into 64-bit protected mode, you need to enable paging while EFER.LMA=1. For this to work, CS.L must be 0. Currently, we load the segments before CR0 and CR4, which means that if RSM returns into 64-bit protected mode CS.L is already 1 and everything breaks. Luckily, CS.L=0 is always the case when executing RSM, because it is forbidden to execute RSM from 64-bit protected mode. Hence it is enough to load CR0 and CR4 first, and only then the segments.

2015-10-14tipc: eliminate risk of stalled link synchronizationJon Paul Maloy1-3/+3
In commit 6e498158a827 ("tipc: move link synch and failover to link aggregation level") we introduced a new mechanism for performing link failover and synchronization. We have now detected a bug in this mechanism. During link synchronization we use the arrival of any packet on the tunnel link to trig a check for whether it has reached the synchronization point or not. This has turned out to be too permissive, since it may cause an arriving non-last SYNCH packet to end the synch state, just to see the next SYNCH packet initiate a new synch state with a new, higher synch point. This is not fatal, but should be avoided, because it may significantly extend the synchronization period, while at the same time we are not allowed to send NACKs if packets are lost. In the worst case, a low-traffic user may see its traffic stall until a LINK_PROTOCOL state message trigs the link to leave synchronization state. At the same time, LINK_PROTOCOL packets which happen to have a (non- valid) sequence number lower than the tunnel link's rcv_nxt value will be consistently dropped, and will never be able to resolve the situation described above. We fix this by exempting LINK_PROTOCOL packets from the sequence number check, as they should be. We also reduce (but don't completely eliminate) the risk of entering multiple synchronization states by only allowing the (logically) first SYNCH packet to initiate a synchronization state. This works independently of actual packet arrival order.

Revert the commit e2ca690b657f ("ipv4/icmp: redirect messages can use the ingress daddr as source"), which tried to introduce a more suitable behaviour for ICMP redirect messages generated by VRRP routers. However RFC 5798 section 8.1.1 states: The IPv4 source address of an ICMP redirect should be the address that the end-host used when making its next-hop routing decision. while said commit used the generating packet destination address, which do not match the above and in most cases leads to no redirect packets to be generated.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-10-13 This series contains updates to i40e, i40evf, ixgbe and fm10k. Carolyn cleans up ndo_bridge_getlink() by flagging a parameter as __always_unused, since it is never used. Adds a member to the nvm_info struct to store OEM version info to be output either by OID or ethtool. Neerav cleans up a remaining bit shift to use BIT() macro. Mitch fixes the i40evf driver to properly handle calls to its ndo_set_mac_address() method. It did not properly check to see if the override would be allowed by the PF driver, and it never removed the old address from its filter list. Cleaned up the use of i40e_enable_vf_mappings() in i40e_alloc_vfs(), since it is just redundant since we already call it by i40e_reset_vf(). Fixed a possible panic in some circumstances where the firmware may fail to allocate a VSI for a VF by checking the return value from i40e_alloc_vf_res() and don't try to configure the device further if it failed. Greg fixes the parsing of CEE App TLVs so the caller does not have to consider whether the App came from a CEE or IEEE DCBx negotiation. Shannon moves the device ids into a standalone file due to the desire to write user-land drivers (and other requests) without needing the rest of the include files. Catherine adds the ability to save the module information from get_phy_capabilities() to be used to determine which speeds the module supports. Also cleaned up the PHY structure by removing unused members and add the ability to store the PHY capabilities reported by the firmware. Emil modifies ixgbe to ensure that flow control packets initiated by the VF are dropped and reported as spoofed. Jacob cleans up the fm10k driver to avoid buffer overflow by using sprintf(), so convert to using snprintf(). Also fixed the use of an enum as a boolean, so check for the actual value of NETREG_UNINITIALIZED in case it ever changes from the current value of zero. v2: Dropped patch 11 of the original series, which added functions that were never used. ==================== Signed-off-by: David S.

Remove unused members in the PHY structure and add a new member to store all the capabilities the PHY has as reported by the FW. This information will help us determine what speeds the device is capable of when link is down. Also add an enum to decode the PHY types the NVM is capable of. Use the phy_types variable to determine what phy types are possible when link is down instead of device id as it will be more accurate. When on a backplane device, we do not support changing any settings, however we should display all the phy_types we are capable of so if we see a backplane dev ID set supported and advertised purely based on the phy_types variable.

2015-10-13i40e/i40evf: Add module_types and update_link_infoCatherine Sullivan6-9/+76

Also add a new function update_link_info which updates the module_types parameter and then calls get_link_info. This function should be called in place of get_link_info so that the module_types variable stays up-to-date with the rest of the link information. The EAS table does not reflect the values that are actually returned, so instead, basing these values on the Ethernet compliance codes specified in table 33 of SFF-8436 as these have been accurate. Use the new variable in ethtool to differentiate between a 10G/1G dual speed fiber module and a 10G only module.

2015-10-14PM / Domains: Fix validation of latency constraints in genpd governorUlf Hansson1-16/+6
Commit ba2bbfbf6307 (PM / Domains: Remove intermediate states from the power off sequence) changed the power off sequence in genpd. That also required some updates regarding the validation of latency constraints in the genpd governor. Unfortunate that wasn't covered, so let's fix this. From a runtime PM and latency point of view, we need to consider the worst case scenario while validating latency constraints. That's typically when a call to pm_runtime_get_sync() needs to wait for a ongoing runtime suspend operation to be carried out, as it then also needs to wait for the device to be runtime resumed again. The above mentioned commit made the genpd governor's ->stop_ok() callback responsible of validating genpd's device's runtime suspend/resume latency. In other words, the constraint needs to be validated towards the relevant latencies present in genpd's ->runtime_suspend|resume() callbacks. Earlier, that included latencies from the ->stop|start() callbacks, but as ->save|restore_state() are now also being invoked from genpd's ->runtime_suspend|resume() and to comply with the worst case scenario, let's take also those latencies into account.

An SMI to a halted VCPU must wake it up, hence a VCPU with a pending SMI must be considered runnable. Fixes: 64d6067057d9658acb8675afcfba549abdb7fc16 Cc: [email protected] Signed-off-by: Paolo Bonzini <[email protected]>

2015-10-13KVM: x86: map/unmap private slots in __x86_set_memory_regionPaolo Bonzini1-32/+30
Otherwise, two copies (one of them never populated and thus bogus) are allocated for the regular and SMM address spaces. This breaks SMM with EPT but without unrestricted guest support, because the SMM copy of the identity page map is all zeros. By moving the allocation to the caller we also remove the last vestiges of kernel-allocated memory regions (not accessible anymore in userspace since commit b74a07beed0e, "KVM: Remove kernel-allocated memory regions", 2010-06-21); that is a nice bonus.

2015-10-13KVM: x86: build kvm_userspace_memory_region in x86_set_memory_regionPaolo Bonzini3-42/+21
The next patch will make x86_set_memory_region fill the userspace_addr. Since the struct is not used untouched anymore, it makes sense to build it in x86_set_memory_region directly; it also simplifies the callers.

2015-10-13can: avoid using timeval for uapiArnd Bergmann2-6/+16
The can subsystem communicates with user space using a bcm_msg_head header, which contains two timestamps. This is problematic for multiple reasons: a) The structure layout is currently incompatible between 64-bit user space and 32-bit user space, and cannot work in compat mode (other than x32). b) The timeval structure layout will change in 32-bit user space when we fix the y2038 overflow problem by redefining time_t to 64-bit, making new 32-bit user space incompatible with the current kernel interface. Cars last a long time and often use old kernels, so the actual users of this code are the most likely ones to migrate to y2038 safe user space. This tries to work around part of the problem by changing the publicly visible user interface in the header, but not the binary interface. Fortunately, the values passed around in the structure are relative times and do not actually suffer from the y2038 overflow, so 32-bit is enough here. We replace the use of 'struct timeval' with a newly defined 'struct bcm_timeval' that uses the exact same binary layout as before and that still suffers from problem a) but not problem b). The downside of this approach is that any user space program that currently assigns a timeval structure to these members rather than writing the tv_sec/tv_usec portions individually will suffer a compile-time error when built with an updated kernel header. Fixing this error makes it work fine with old and new headers though. We could address problem a) by using '__u32' or 'int' members rather than 'long', but that would have a more significant downside in also breaking support for all existing 64-bit user binaries that might be using this interface, which is likely not acceptable.
