2020-09-13staging: wfx: drop 'secure link' featureJérôme Pouiller
The Secure Link (slk) feature allows to encrypt (and authenticate) the traffic between the host and the device. The official implementation of this feature relies on mbedTLS. For that reason, this implementation is not included in the current driver. To be included, the implementation has to rely on kernel crypto API instead of mbedTLS. So, for now, the driver contained stub functions waiting for the new implementation based on kernel crypto API. This new implementation represent a bunch of work and it is unlikely to be done in near future. Moreover, we strongly dislike to maintain useless code. So, drop all the code related to secure link. Whoever wants to implement secure link should revert this patch before starting to work on it.

2020-09-12SVM: nSVM: correctly restore GIF on vmexit from nesting after migrationMaxim Levitsky
Currently code in svm_set_nested_state copies the current vmcb control area to L1 control area (hsave->control), under assumption that it mostly reflects the defaults that kvm choose, and later qemu overrides these defaults with L2 state using standard KVM interfaces, like KVM_SET_REGS. However nested GIF (which is AMD specific thing) is by default is true, and it is copied to hsave area as such. This alone is not a big deal since on VMexit, GIF is always set to false, regardless of what it was on VM entry. However in nested_svm_vmexit we were first were setting GIF to false, but then we overwrite the control fields with value from the hsave area. (including the nested GIF field itself if GIF virtualization is enabled). Now on normal vm entry this is not a problem, since GIF is usually false prior to normal vm entry, and this is the value that copied to hsave, and then restored, but this is not always the case when the nested state is loaded as explained above. To fix this issue, move svm_set_gif after we restore the L1 control state in nested_svm_vmexit, so that even with wrong GIF in the saved L1 control area, we still clear GIF as the spec says.

2020-09-12openrisc: Fix issue with get_user for 64-bit valuesStafford Horne
A build failure was raised by kbuild with the following error. drivers/android/binder.c: Assembler messages: drivers/android/binder.c:3861: Error: unrecognized keyword/register name `l.lwz ?ap,4(r24)' drivers/android/binder.c:3866: Error: unrecognized keyword/register name `l.addi ?ap,r0,0' The issue is with 64-bit get_user() calls on openrisc. I traced this to a problem where in the internally in the get_user macros there is a cast to long __gu_val this causes GCC to think the get_user call is 32-bit. This binder code is really long and GCC allocates register r30, which triggers the issue. The 64-bit get_user asm tries to get the 64-bit pair register, which for r30 overflows the general register names and returns the dummy register ?ap. The fix here is to move the temporary variables into the asm macros. We use a 32-bit __gu_tmp for 32-bit and smaller macro and a 64-bit tmp in the 64-bit macro. The cast in the 64-bit macro has a trick of casting through __typeof__((x)-(x)) which avoids the below warning. This was barrowed from riscv. arch/openrisc/include/asm/uaccess.h:240:8: warning: cast to pointer from integer of different size I tested this in a small unit test to check reading between 64-bit and 32-bit pointers to 64-bit and 32-bit values in all combinations. Also I ran make C=1 to confirm no new sparse warnings came up. It all looks clean to me.

2020-09-12x86/kvm: don't forget to ACK async PF IRQVitaly Kuznetsov
Merge commit 26d05b368a5c0 ("Merge branch 'kvm-async-pf-int' into HEAD") tried to adapt the new interrupt based async PF mechanism to the newly introduced IDTENTRY magic but unfortunately it missed the fact that DEFINE_IDTENTRY_SYSVEC() doesn't call ack_APIC_irq() on its own and all DEFINE_IDTENTRY_SYSVEC() users have to call it manually. As the result all multi-CPU KVM guest hang on boot when KVM_FEATURE_ASYNC_PF_INT is present. The breakage went unnoticed because no KVM userspace (e.g. QEMU) currently set it (and thus async PF mechanism is currently disabled) but we're about to change that.

It's possible that the user specifies an interval that couldn't allow any packet to be transmitted. This also avoids the issue of the hrtimer handler starving the other threads because it's running too often. The solution is to reject interval sizes that according to the current link speed wouldn't allow any packet to be transmitted.

2020-09-11RISC-V: Take text_mutex in ftrace_init_nop()Palmer Dabbelt
Without this we get lockdep failures. They're spurious failures as SMP isn't up when ftrace_init_nop() is called. As far as I can tell the easiest fix is to just take the lock, which also seems like the safest fix.
