* irqchip/irq-mvebu-icu: Clarify the reset operation of configured interruptsMiquel Raynal2018-10-021-2/+6
| | | | | | | | | | Rewrite a small section to clarify the reset operation of interrupts already configured by ATF that we want to handle in the driver. This will simplify the introduction of System Error Interrupts support.

* irqchip/irq-mvebu-icu: Fix wrong private data retrievalMiquel Raynal2018-10-021-1/+1
| | | | | | | | | | | | | | | | | | | The irq_domain structure has an host_data pointer that just stores private data. It is meant to not be touched by the IRQ core. However, when it comes to MSI, the MSI layer adds its own private data there with a structure that also has a host_data pointer. Because this IRQ domain is an MSI domain, to access private data we should do a d->host_data->host_data, also wrapped as 'platform_msi_get_host_data()'. This bug was lying there silently because the 'icu' structure retrieved this way was just called by dev_err(), only producing a '(NULL device *):' output on the console.

* genirq/msi: Allow creation of a tree-based irqdomain for platform-msiMarc Zyngier2018-10-022-11/+20
| | | | | | | | | | | | | | | platform_msi_create_device_domain() always creates a revmap-based irqdomain, which has the drawback of requiring the number of MSIs that can be allocated ahead of time. This is not always possible, and we sometimes need to use a tree-based irqdomain instead. Add a new platform_msi_create_device_tree_domain() helper to that effect.

| | | | | | | | | | | | | | | | | Pending tables for the redistributors are currently allocated one at a time as each CPU boots. This is causing some grief for Linux/RT (allocation from within a CPU hotplug notifier is frown upon). Let's move this allocation to take place at init time, when we only have a single CPU. It means we're allocating memory for CPUs that are not online yet, but most system will boot all of their CPUs anyway, so that's not completely wasted.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When page-table entries are set, the compiler might optimize their assignment by using multiple instructions to set the PTE. This might turn into a security hazard if the user somehow manages to use the interim PTE. L1TF does not make our lives easier, making even an interim non-present PTE a security hazard. Using WRITE_ONCE() to set PTEs and friends should prevent this potential security hazard. I skimmed the differences in the binary with and without this patch. The differences are (obviously) greater when CONFIG_PARAVIRT=n as more code optimizations are possible. For better and worse, the impact on the binary with this patch is pretty small. Skimming the code did not cause anything to jump out as a security hazard, but it seems that at least move_soft_dirty_pte() caused set_pte_at() to use multiple writes.

The previous state becomes the new target state. The rollback happens in undo_cpu_down() which increments the state unconditionally even if the state is already the same as the target. As a consequence the next CPU hotplug operation will start at the wrong state. This is easily to observe when __cpu_disable() fails. Prevent the unconditional undo by checking the state vs. target before incrementing state and fix up the consequently wrong conditional in the unplug code which handles the failure of the final CPU take down on the control CPU side.

This refreshing of the index used to happen, but was removed in cdf2bc632ebc ("scripts/setlocalversion on write-protected source tree", 2013-06-14) due to issues with a read-only filesystem. If the index is not refreshed, one runs into problems. E.g. as described in [0], git stores the uid in its index, so even if just the uid has changed (or git is tricked into thinking so), then we will think the tree is dirty. So as in [1], if you package linux-git with a system that uses fakeroot(1), you get a "-dirty" version. Unless you manually $(git update-index --refresh) themselves. The simplest solution seems to be $(git status --porcelain), with an additional flag saying "ignore untracked files". It seems clearer about what it does, and avoids issues regarding cached indexes and writable filesystems, but still has stable output for scripting.

When L1 executes VMLAUNCH/VMRESUME, L0 needs to evaluate if this pending event should cause an exit from L2 to L1 or delivered directly to L2 (e.g. In case L1 don't intercept EXTERNAL_INTERRUPT). Usually this would be handled by L0 requesting a IRQ/NMI window by setting VMCS accordingly. However, this setting was done on VMCS01 and now VMCS02 is active instead. Thus, when L1 executes VMLAUNCH/VMRESUME we force L0 to perform pending event evaluation by requesting a KVM_REQ_EVENT. Note that above scenario exists when L1 KVM is about to enter L2 but requests an "immediate-exit". As in this case, L1 will disable-interrupts and then send a self-IPI before entering L2.
