2016-03-23soc: qcom: Add in-rush current mitigation driverArun KS
On few recent targets APSS L2 memory is moved to APC domain which were earlier on Mx domain. This can cause inrush current while bringing up huge memories like modem and adsp. To mitigate inrush current, bring up comparatively lesser memory in size(for eg MDP memory) before bringing up huge memories like modem or adsp. This way MDP memory introduce an intermediate load on MX rail. During boot, gdsc driver will set MEM and PERIPHERAL bits. This driver makes sure that dependent subsystems are powered up. Once done, call gdsc_allow_clear_retention() API to allow retention of MDP memories. Change-Id: I54011eb1b6cc38b2c33a67b8b9cc5eaadbd42c6a Signed-off-by: Arun KS <arunks@codeaurora.org>

2016-03-23soc: qcom: Add kernel_protect library and initcallMitchel Humpherys
It's good security practice to make your executable code read-only. On hypervisor-enabled targets, this can be trivially accomplished by removing the writable attribute from all stage-2 mappings of the kernel text. Add a small library and initcall to do this. Due to constraints on the hypervisor, this needs to happen before all of the cores are brought out of reset, so make it an early_initcall.

2016-03-22soc: qcom: scm: Skip Kasan sanitization of the SCM driverTrilok Soni
SCM (Secure Channel Manager) driver is used to communicate with the secure world entities like trustzone and hypervisor. As a part of the communication we expect to give certain input, output operands and the caller of the scm_callX API would expect that output values or return values of the scm_callX should not get corrupted (if they depend on it). Due to Kasan instrumentation of the SCM driver following code is getting instrumented with Kasan __asan_store8_noabort APIs which would internally check if the memory access is allowed and it is the functionality of the Kasan to check/instrument the load and stores. if (ret1) *ret1 = r1; if (ret2) *ret2 = r2; if (ret3) *ret3 = r2; All will be fine for the first *ret1 = r1; execution since GCC has generated the code which saves the x1 value (r1) into the another register but the execution of the __asan_store8_noabort API after the saving of the register corrupts the x2 and x3 when it returns. GCC has no knowledge at this point to save the x2 and x3. Due to this x2 and x3 is loaded with the Kasan shadow offset value and Kasan shifted (>> 3) address. Since x2 and x3 (r2 and r3 in the code above) would be used as the ret2 and ret3 for the caller of the scm_callX API the caller would get the wrong return values (if it needs them). QSEECOM is one such driver which uses these ret2 and ret3 values and due to this corruption QSEECOM driver was treating it as SCM call failure, though the bug described above due to Kasan instrumentation would be applicable to any caller needing the right values of the ret2 and ret3. SCM driver is very small and simple and we would not expect the Out of bound or use-after-free errors for it, so it would be fine to skip it from the Kasan instrumentation.

Buffers shared with hypervisor might undergo some cache maintenance on the hypervisor side. Currently, we're passing a buffer that might not be cache-aligned (source_vm_list), so when the hypervisor does some cache maintenance on it they might be corrupting data. Fix this by ensuring that all buffers being shared with the hypervisor are cache-aligned by kmalloc'ing and memcpy'ing the source_vm_list before sending it across.
