[PATCH v2 0/5] selftests/ima: add kexec and kernel module tests

by Mimi Zohar

The kernel can be configured to require kexec kernel images and kernel modules are signed. An IMA policy can be specified on the boot command line or a custom IMA policy loaded requiring the kexec kernel image and kernel modules be signed. In addition, systems booted in secure boot mode with the IMA architecture specific policy enabled, require validly signed kexec kernel images and kernel modules. There are two methods of signing kernel images and two methods of signing kernel modules. In addition, there are two syscalls for each. kernel image: PE signature, IMA signature kexec syscalls: kexec_load, kexec_file_load Both the PE and IMA kernel image signature can only be verified when loaded via the kexec_file_load syscall. kernel moodule: appended signature, IMA signature kernel module syscalls: init_module, finit_module The appended kernel module signature can be verified when the kernel module is loaded via either syscall. The IMA kernel module signature can only be verified when the kernel module is loaded via the finit_module syscall. The selftests in this patch set verify that only signed kernel images and kernel modules are loaded as required, based on the kernel config, the secure boot mode, and the IMA runtime policy. Loading a kernel image or kernel module requires root privileges. To run just the IMA selftests: sudo make TARGETS=ima kselftest Mimi Zohar (5): selftests/ima: cleanup the kexec selftest selftests/ima: define a set of common functions selftests/ima: define common logging functions selftests/ima: kexec_file_load syscall test selftests/ima: loading kernel modules tools/testing/selftests/ima/Makefile | 3 +- tools/testing/selftests/ima/common_lib.sh | 154 ++++++++++++++++ tools/testing/selftests/ima/test_kernel_module.sh | 96 ++++++++++ .../testing/selftests/ima/test_kexec_file_load.sh | 195 +++++++++++++++++++++ tools/testing/selftests/ima/test_kexec_load.sh | 53 ++---- 5 files changed, 463 insertions(+), 38 deletions(-) create mode 100755 tools/testing/selftests/ima/common_lib.sh create mode 100755 tools/testing/selftests/ima/test_kernel_module.sh create mode 100755 tools/testing/selftests/ima/test_kexec_file_load.sh -- 2.7.5

[PATCH] selftests/x86: Support Atom for syscall_arg_fault test

by Tong Bo

Atom-based CPUs trigger stack fault when invoke 32-bit SYSENTER instruction with invalid register values. So we also need sigbus handling in this case. Following is assembly when the fault expception happens. (gdb) disassemble $eip Dump of assembler code for function __kernel_vsyscall: 0xf7fd8fe0 <+0>: push %ecx 0xf7fd8fe1 <+1>: push %edx 0xf7fd8fe2 <+2>: push %ebp 0xf7fd8fe3 <+3>: mov %esp,%ebp 0xf7fd8fe5 <+5>: sysenter 0xf7fd8fe7 <+7>: int $0x80 => 0xf7fd8fe9 <+9>: pop %ebp 0xf7fd8fea <+10>: pop %edx 0xf7fd8feb <+11>: pop %ecx 0xf7fd8fec <+12>: ret End of assembler dump. Accroding to Intel SDM, this could also be a Stack Segment Fault(#SS, 12), except a normal Page Fault(#PF, 14). Especially, in section 6.9 of Vol.3A, both stack and page faults are within the 10th(lowest priority) class, and as it said, "exceptions within each class are implementation-dependent and may vary from processor to processor". It's expected for processors like Intel Atom to trigger stack fault(sigbus), while we get page fault(sigsegv) from common Core processors.

[PATCH v10 00/12] arm64: untag user pointers passed to the kernel

by Andrey Konovalov

This patchset is meant to be merged together with "arm64 relaxed ABI" [1]. arm64 has a feature called Top Byte Ignore, which allows to embed pointer tags into the top byte of each pointer. Userspace programs (such as HWASan, a memory debugging tool [2]) might use this feature and pass tagged user pointers to the kernel through syscalls or other interfaces. Right now the kernel is already able to handle user faults with tagged pointers, due to these patches: 1. 81cddd65 ("arm64: traps: fix userspace cache maintenance emulation on a tagged pointer") 2. 7dcd9dd8 ("arm64: hw_breakpoint: fix watchpoint matching for tagged pointers") 3. 276e9327 ("arm64: entry: improve data abort handling of tagged pointers") This patchset extends tagged pointer support to syscall arguments. For non-memory syscalls this is done by untaging user pointers when the kernel performs pointer checking to find out whether the pointer comes from userspace (most notably in access_ok). The untagging is done only when the pointer is being checked, the tag is preserved as the pointer makes its way through the kernel. Since memory syscalls (mmap, mprotect, etc.) don't do memory accesses but rather deal with memory ranges, untagged pointers are better suited to describe memory ranges internally. Thus for memory syscalls we untag pointers completely when they enter the kernel. One of the alternative approaches to untagging that was considered is to completely strip the pointer tag as the pointer enters the kernel with some kind of a syscall wrapper, but that won't work with the countless number of different ioctl calls. With this approach we would need a custom wrapper for each ioctl variation, which doesn't seem practical. The following testing approaches has been taken to find potential issues with user pointer untagging: 1. Static testing (with sparse [3] and separately with a custom static analyzer based on Clang) to track casts of __user pointers to integer types to find places where untagging needs to be done. 2. Static testing with grep to find parts of the kernel that call find_vma() (and other similar functions) or directly compare against vm_start/vm_end fields of vma. 3. Static testing with grep to find parts of the kernel that compare user pointers with TASK_SIZE or other similar consts and macros. 4. Dynamic testing: adding BUG_ON(has_tag(addr)) to find_vma() and running a modified syzkaller version that passes tagged pointers to the kernel. Based on the results of the testing the requried patches have been added to the patchset. This patchset has been merged into the Pixel 2 kernel tree and is now being used to enable testing of Pixel 2 phones with HWASan. This patchset is a prerequisite for ARM's memory tagging hardware feature support [4]. Thanks!
