* | | arm64: kaslr: Fix up the kernel image alignmentNeeraj Upadhyay2017-03-221-3/+7

The offset is masked after resizing. There are cases, where after masking, we may still have kernel image extending across boundary. This eventually results in only 2MB block getting mapped while creating the page tables. This results in data aborts while accessing unmapped regions during second relocation (with kaslr offset) in __primary_switch. To fix this problem, round up the kernel image size, by swapper block size, before adding it for correction. For example consider below case, where kernel image still crosses 1GB alignment boundary, after masking the offset, which is fixed by rounding up kernel image size. SWAPPER_TABLE_SHIFT = 30 Swapper using section maps with section size 2MB.

Since commit a4023f682739439b ("arm64: Add hypervisor safe helper for checking constant capabilities"), which was introduced around the same time, cpus_have_cap() doesn't try to use a static key, and must always perform a load, test, and consitional branch (likely a tbnz for the latter two). Elsewhere, we moved to using cpus_have_const_cap(), which can use a static key (i.e. a non-conditional branch), which is patched at runtime when the feature is detected. This patch makes system_uses_ttbr0_pan() use cpus_have_const_cap(). The static key is likely a win for hot-paths like the uacccess primitives, and this makes our usage consistent regardless.

As with other recent changes, this patch uses lm_alias() to solve this. We could instead use NUMA_NO_NODE, as x86 does for all shadow allocations, though we'll likely want the "real" memory shadow to be backed from its corresponding nid anyway, so we may as well be consistent and find the nid for the image shadow.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On Qualcomm Datacenter Technologies QDF2400 SoCs, the ITS hardware implementation uses 16Bytes for Interrupt Translation Entry (ITE), but reports an incorrect value of 8Bytes in GITS_TYPER.ITTE_size. It might cause kernel memory corruption depending on the number of MSI(x) that are configured and the amount of memory that has been allocated for ITEs in its_create_device().

As configurable disables/enables are added to the architecture (controlled by RES1/RES0 bits respectively), with associated synchronous exceptions, it may be possible for a guest to trigger exceptions with classes that we don't recognise. While we can't service these exceptions in a manner useful to the guest, we can avoid bringing down the host. Per ARM DDI 0487A.k_iss10775, page D7-1937, EC values within the range 0x00 - 0x2c are reserved for future use with synchronous exceptions, and EC values within the range 0x2d - 0x3f may be used for either synchronous or asynchronous exceptions. The patch makes KVM handle any unknown EC by injecting an UNDEFINED exception into the guest, with a corresponding (ratelimited) warning in the host dmesg. We could later improve on this with with a new (opt-in) exit to the host userspace.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When invalidating guest TLBs, special care must be taken to actually shoot the guest TLBs and not the host ones if we're running on a VHE system. This is controlled by the HCR_EL2.TGE bit, which we forget to clear before invalidating TLBs. Address the issue by introducing two wrappers (__tlb_switch_to_guest and __tlb_switch_to_host) that take care of both the VTTBR_EL2 and HCR_EL2.TGE switching.

Replaces the existing definition with one that defines the programmable replicator, using the "qcom,coresight-replicator1x" driver that provides the correct functionality for CoreSight programmable replicators.

This means that various files which relied on the full <linux/signal.h> need to be updated to gain an explicit dependency on it. Update the code that relies on sched.h's inclusion of the <linux/signal.h> header.
