January 2024 - Linux-kselftest-mirror

From: Jeff Xu <jeffxu(a)google.com> This patchset proposes a new mseal() syscall for the Linux kernel. In a nutshell, mseal() protects the VMAs of a given virtual memory range against modifications, such as changes to their permission bits. Modern CPUs support memory permissions, such as the read/write (RW) and no-execute (NX) bits. Linux has supported NX since the release of kernel version 2.6.8 in August 2004 [1]. The memory permission feature improves the security stance on memory corruption bugs, as an attacker cannot simply write to arbitrary memory and point the code to it. The memory must be marked with the X bit, or else an exception will occur. Internally, the kernel maintains the memory permissions in a data structure called VMA (vm_area_struct). mseal() additionally protects the VMA itself against modifications of the selected seal type. Memory sealing is useful to mitigate memory corruption issues where a corrupted pointer is passed to a memory management system. For example, such an attacker primitive can break control-flow integrity guarantees since read-only memory that is supposed to be trusted can become writable or .text pages can get remapped. Memory sealing can automatically be applied by the runtime loader to seal .text and .rodata pages and applications can additionally seal security critical data at runtime. A similar feature already exists in the XNU kernel with the VM_FLAGS_PERMANENT [3] flag and on OpenBSD with the mimmutable syscall [4]. Also, Chrome wants to adopt this feature for their CFI work [2] and this patchset has been designed to be compatible with the Chrome use case. Two system calls are involved in sealing the map: mmap() and mseal(). The new mseal() is an syscall on 64 bit CPU, and with following signature: int mseal(void addr, size_t len, unsigned long flags) addr/len: memory range. flags: reserved. mseal() blocks following operations for the given memory range. 1> Unmapping, moving to another location, and shrinking the size, via munmap() and mremap(), can leave an empty space, therefore can be replaced with a VMA with a new set of attributes. 2> Moving or expanding a different VMA into the current location, via mremap(). 3> Modifying a VMA via mmap(MAP_FIXED). 4> Size expansion, via mremap(), does not appear to pose any specific risks to sealed VMAs. It is included anyway because the use case is unclear. In any case, users can rely on merging to expand a sealed VMA. 5> mprotect() and pkey_mprotect(). 6> Some destructive madvice() behaviors (e.g. MADV_DONTNEED) for anonymous memory, when users don't have write permission to the memory. Those behaviors can alter region contents by discarding pages, effectively a memset(0) for anonymous memory. In addition: mmap() has two related changes. The PROT_SEAL bit in prot field of mmap(). When present, it marks the map sealed since creation. The MAP_SEALABLE bit in the flags field of mmap(). When present, it marks the map as sealable. A map created without MAP_SEALABLE will not support sealing, i.e. mseal() will fail. Applications that don't care about sealing will expect their behavior unchanged. For those that need sealing support, opt-in by adding MAP_SEALABLE in mmap(). The idea that inspired this patch comes from Stephen Röttger’s work in V8 CFI [5]. Chrome browser in ChromeOS will be the first user of this API. Indeed, the Chrome browser has very specific requirements for sealing, which are distinct from those of most applications. For example, in the case of libc, sealing is only applied to read-only (RO) or read-execute (RX) memory segments (such as .text and .RELRO) to prevent them from becoming writable, the lifetime of those mappings are tied to the lifetime of the process. Chrome wants to seal two large address space reservations that are managed by different allocators. The memory is mapped RW- and RWX respectively but write access to it is restricted using pkeys (or in the future ARM permission overlay extensions). The lifetime of those mappings are not tied to the lifetime of the process, therefore, while the memory is sealed, the allocators still need to free or discard the unused memory. For example, with madvise(DONTNEED). However, always allowing madvise(DONTNEED) on this range poses a security risk. For example if a jump instruction crosses a page boundary and the second page gets discarded, it will overwrite the target bytes with zeros and change the control flow. Checking write-permission before the discard operation allows us to control when the operation is valid. In this case, the madvise will only succeed if the executing thread has PKEY write permissions and PKRU changes are protected in software by control-flow integrity. Although the initial version of this patch series is targeting the Chrome browser as its first user, it became evident during upstream discussions that we would also want to ensure that the patch set eventually is a complete solution for memory sealing and compatible with other use cases. The specific scenario currently in mind is glibc's use case of loading and sealing ELF executables. To this end, Stephen is working on a change to glibc to add sealing support to the dynamic linker, which will seal all non-writable segments at startup. Once this work is completed, all applications will be able to automatically benefit from these new protections.

[PATCH bpf-next v3 0/3] Annotate kfuncs in .BTF_ids section

by Daniel Xu

=== Description === This is a bpf-treewide change that annotates all kfuncs as such inside .BTF_ids. This annotation eventually allows us to automatically generate kfunc prototypes from bpftool. We store this metadata inside a yet-unused flags field inside struct btf_id_set8 (thanks Kumar!). pahole will be taught where to look. More details about the full chain of events are available in commit 3's description. The accompanying pahole changes (still needs some cleanup) can be viewed here on this "frozen" branch [0]. [0]: https://github.com/danobi/pahole/tree/kfunc_btf-mailed === Changelog === Changes from v2: * Only WARN() for vmlinux kfuncs Changes from v1: * Move WARN_ON() up a call level * Also return error when kfunc set is not properly tagged * Use BTF_KFUNCS_START/END instead of flags * Rename BTF_SET8_KFUNC to BTF_SET8_KFUNCS Daniel Xu (3): bpf: btf: Support flags for BTF_SET8 sets bpf: btf: Add BTF_KFUNCS_START/END macro pair bpf: treewide: Annotate BPF kfuncs in BTF drivers/hid/bpf/hid_bpf_dispatch.c | 8 +++---- fs/verity/measure.c | 4 ++-- include/linux/btf_ids.h | 21 +++++++++++++++---- kernel/bpf/btf.c | 8 +++++++ kernel/bpf/cpumask.c | 4 ++-- kernel/bpf/helpers.c | 8 +++---- kernel/bpf/map_iter.c | 4 ++-- kernel/cgroup/rstat.c | 4 ++-- kernel/trace/bpf_trace.c | 8 +++---- net/bpf/test_run.c | 8 +++---- net/core/filter.c | 16 +++++++------- net/core/xdp.c | 4 ++-- net/ipv4/bpf_tcp_ca.c | 4 ++-- net/ipv4/fou_bpf.c | 4 ++-- net/ipv4/tcp_bbr.c | 4 ++-- net/ipv4/tcp_cubic.c | 4 ++-- net/ipv4/tcp_dctcp.c | 4 ++-- net/netfilter/nf_conntrack_bpf.c | 4 ++-- net/netfilter/nf_nat_bpf.c | 4 ++-- net/xfrm/xfrm_interface_bpf.c | 4 ++-- net/xfrm/xfrm_state_bpf.c | 4 ++-- .../selftests/bpf/bpf_testmod/bpf_testmod.c | 8 +++---- 22 files changed, 81 insertions(+), 60 deletions(-) -- 2.42.1

[PATCH bpf-next v2 00/15] Improvements for tracking scalars in the BPF verifier

by Maxim Mikityanskiy

From: Maxim Mikityanskiy <maxim(a)isovalent.com> The goal of this series is to extend the verifier's capabilities of tracking scalars when they are spilled to stack, especially when the spill or fill is narrowing. It also contains a fix by Eduard for infinite loop detection and a state pruning optimization by Eduard that compensates for a verification complexity regression introduced by tracking unbounded scalars. These improvements reduce the surface of false rejections that I saw while working on Cilium codebase. Patch 1 (Maxim): Fix for an existing test, it will matter later in the series. Patches 2-3 (Eduard): Fixes for false rejections in infinite loop detection that happen in the selftests when my patches are applied. Patches 4-5 (Maxim): Fix the inconsistency of find_equal_scalars that was possible if 32-bit spills were made. Patches 6-11 (Maxim): Support the case when boundary checks are first performed after the register was spilled to the stack. Patches 12-13 (Maxim): Support narrowing fills. Patches 14-15 (Eduard): Optimization for state pruning in stacksafe() to mitigate the verification complexity regression. veristat -e file,prog,states -f '!states_diff<50' -f '!states_pct<10' -f '!states_a<10' -f '!states_b<10' -C ... * Without patch 14: File Program States (A) States (B) States (DIFF) -------------------- ------------ ---------- ---------- ---------------- bpf_xdp.o tail_lb_ipv6 3877 2936 -941 (-24.27%) pyperf180.bpf.o on_event 8422 10456 +2034 (+24.15%) pyperf600.bpf.o on_event 22259 37319 +15060 (+67.66%) pyperf600_iter.bpf.o on_event 400 540 +140 (+35.00%) strobemeta.bpf.o on_event 4702 13435 +8733 (+185.73%) * With patch 14: File Program States (A) States (B) States (DIFF) -------------------- ------------ ---------- ---------- -------------- bpf_xdp.o tail_lb_ipv6 3877 2937 -940 (-24.25%) pyperf600_iter.bpf.o on_event 400 500 +100 (+25.00%) v2 changes: Fixed comments in patch 1, moved endianness checks to header files in patch 12 where possible, added Eduard's ACKs.

[PATCH] selftests/livepatch: fix and refactor new dmesg message code

by Joe Lawrence

The livepatching kselftests rely on comparing expected vs. observed dmesg output. After each test, new dmesg entries are determined by the 'comm' utility comparing a saved, pre-test copy of dmesg to post-test dmesg output. Alexander reports that the 'comm --nocheck-order -13' invocation used by the tests can be confused when dmesg entry timestamps vary in magnitude (ie, "[ 98.820331]" vs. "[ 100.031067]"), in which case, additional messages are reported as new. The unexpected entries then spoil the test results. Instead of relying on 'comm' or 'diff' to determine new testing dmesg entries, refactor the code: - pre-test : log a unique canary dmesg entry - test : run tests, log messages - post-test : filter dmesg starting from pre-test message Reported-by: Alexander Gordeev <agordeev(a)linux.ibm.com> Closes: https://lore.kernel.org/live-patching/ZYAimyPYhxVA9wKg@li-008a6a4c-3549-11b… Signed-off-by: Joe Lawrence <joe.lawrence(a)redhat.com> --- .../testing/selftests/livepatch/functions.sh | 37 +++++++++---------- 1 file changed, 17 insertions(+), 20 deletions(-) diff --git a/tools/testing/selftests/livepatch/functions.sh b/tools/testing/selftests/livepatch/functions.sh index c8416c54b463..b1fd7362c2fe 100644 --- a/tools/testing/selftests/livepatch/functions.sh +++ b/tools/testing/selftests/livepatch/functions.sh @@ -42,17 +42,6 @@ function die() { exit 1 } -# save existing dmesg so we can detect new content -function save_dmesg() { - SAVED_DMESG=$(mktemp --tmpdir -t klp-dmesg-XXXXXX) - dmesg > "$SAVED_DMESG" -} - -# cleanup temporary dmesg file from save_dmesg() -function cleanup_dmesg_file() { - rm -f "$SAVED_DMESG" -} - function push_config() { DYNAMIC_DEBUG=$(grep '^kernel/livepatch' /sys/kernel/debug/dynamic_debug/control | \ awk -F'[: ]' '{print "file " $1 " line " $2 " " $4}') @@ -99,7 +88,6 @@ function set_ftrace_enabled() { function cleanup() { pop_config - cleanup_dmesg_file } # setup_config - save the current config and set a script exit trap that @@ -280,7 +268,15 @@ function set_pre_patch_ret { function start_test { local test="$1" - save_dmesg + # Dump something unique into the dmesg log, then stash the entry + # in LAST_DMESG.

[PATCH 0/3] Update LLVM Phabricator and Bugzilla links

by Nathan Chancellor

This series updates all instances of LLVM Phabricator and Bugzilla links to point to GitHub commits directly and LLVM's Bugzilla to GitHub issue shortlinks respectively. I split up the Phabricator patch into BPF selftests and the rest of the kernel in case the BPF folks want to take it separately from the rest of the series, there are obviously no dependency issues in that case. The Bugzilla change was mechanical enough and should have no conflicts. I am aiming this at Andrew and CC'ing other lists, in case maintainers want to chime in, but I think this is pretty uncontroversial (famous last words...). --- Nathan Chancellor (3): selftests/bpf: Update LLVM Phabricator links arch and include: Update LLVM Phabricator links treewide: Update LLVM Bugzilla links arch/arm64/Kconfig | 4 +-- arch/powerpc/Makefile | 4 +-- arch/powerpc/kvm/book3s_hv_nested.c | 2 +- arch/riscv/Kconfig | 2 +- arch/riscv/include/asm/ftrace.h | 2 +- arch/s390/include/asm/ftrace.h | 2 +- arch/x86/power/Makefile | 2 +- crypto/blake2b_generic.c | 2 +- drivers/firmware/efi/libstub/Makefile | 2 +- drivers/gpu/drm/amd/amdgpu/sdma_v4_4_2.c | 2 +- drivers/media/test-drivers/vicodec/codec-fwht.c | 2 +- drivers/regulator/Kconfig | 2 +- include/asm-generic/vmlinux.lds.h | 2 +- include/linux/compiler-clang.h | 2 +- lib/Kconfig.kasan | 2 +- lib/raid6/Makefile | 2 +- lib/stackinit_kunit.c | 2 +- mm/slab_common.c | 2 +- net/bridge/br_multicast.c | 2 +- security/Kconfig | 2 +- tools/testing/selftests/bpf/README.rst | 32 +++++++++++----------- tools/testing/selftests/bpf/prog_tests/xdpwall.c | 2 +- .../selftests/bpf/progs/test_core_reloc_type_id.c | 2 +- 23 files changed, 40 insertions(+), 40 deletions(-) --- base-commit: 0dd3ee31125508cd67f7e7172247f05b7fd1753a change-id: 20240109-update-llvm-links-d03f9d649e1e Best regards, -- Nathan Chancellor <nathan(a)kernel.org>

[PATCH V13 0/7] amd-pstate preferred core

by Meng Li

Hi all: The core frequency is subjected to the process variation in semiconductors. Not all cores are able to reach the maximum frequency respecting the infrastructure limits. Consequently, AMD has redefined the concept of maximum frequency of a part. This means that a fraction of cores can reach maximum frequency. To find the best process scheduling policy for a given scenario, OS needs to know the core ordering informed by the platform through highest performance capability register of the CPPC interface. Earlier implementations of amd-pstate preferred core only support a static core ranking and targeted performance. Now it has the ability to dynamically change the preferred core based on the workload and platform conditions and accounting for thermals and aging. Amd-pstate driver utilizes the functions and data structures provided by the ITMT architecture to enable the scheduler to favor scheduling on cores which can be get a higher frequency with lower voltage. We call it amd-pstate preferred core. Here sched_set_itmt_core_prio() is called to set priorities and sched_set_itmt_support() is called to enable ITMT feature. Amd-pstate driver uses the highest performance value to indicate the priority of CPU. The higher value has a higher priority. Amd-pstate driver will provide an initial core ordering at boot time. It relies on the CPPC interface to communicate the core ranking to the operating system and scheduler to make sure that OS is choosing the cores with highest performance firstly for scheduling the process. When amd-pstate driver receives a message with the highest performance change, it will update the core ranking. Changes from V12->V13: - ACPI: CPPC: - - modify commit message. - - modify handle function of the notify(0x85). - cpufreq: amd-pstate: - - implement update_limits() callback function. - x86: - - pick up Acked-By flag added by Petkov.

Changes from V9->V10: - cpufreq: amd-pstate: - - add judgement for highest_perf. When it is less than 255, the preferred core feature is enabled. And it will set the priority. - - deleset "static u32 max_highest_perf" etc, because amd p-state perferred coe does not require specail process for hotpulg. Changes form V8->V9: - all: - - pick up Tested-By flag added by Oleksandr. - cpufreq: amd-pstate: - - pick up Review-By flag added by Wyes. - - ignore modification of bug. - - add a attribute of prefcore_ranking. - - modify data type conversion from u32 to int. - Documentation: amd-pstate: - - pick up Review-By flag added by Wyes.
