By # utilising this, the kernel is prevented from accessing user data from # outside of trusted paths that perform proper safety checks, such as # copy_{to/from}_user() and friends. # # Userspace access is disabled from early boot and is only enabled when # performing an operation like copy_{to/from}_user(). The register that # controls this (AMR) does not prevent userspace from accessing itself, # so there is no need to save and restore when entering and exiting # userspace. # # This feature has a slight performance impact which I roughly measured # to be 3% slower in the worst case (performing 1GB of 1 byte # read()/write() syscalls), and is gated behind the CONFIG_PPC_KUAP # option for performance-critical builds. # # This feature can be tested by using the lkdtm driver (CONFIG_LKDTM=y) # and performing the following: # # # (echo ACCESS_USERSPACE) > [debugfs]/provoke-crash/DIRECT # # If enabled, this should send SIGSEGV to the thread. # # mpe: Drop the unused paca flags. Zero the UAMOR to be safe. Save the # AMR when we enter the kernel from the kernel and then lock it again. # Restore on the way back to the kernel. This means we handle nesting of # interrupts properly, ie. we are protected inside the page fault # handler caused by a user access. Add paranoid checking of AMR in # switch and syscall return. Add an isync() to prevent_user_access() # # Signed-off-by: Russell Currey <ruscur@russell.cc> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version #
