[PATCH 5.15 0/2] Fix kvm selftest build failures in linux-5.15.y

by Tyler Hicks

From: "Tyler Hicks" <code(a)tyhicks.com> The backport of commit 05c2224d4b04 ("KVM: selftests: Fix number of pages for memory slot in memslot_modification_stress_test") broke the build of the KVM selftest memslot_modification_stress_test.c source file in two ways: - Incorrectly assumed that max_t() was defined despite commit 5cf67a6051ea ("tools/include: Add _RET_IP_ and math definitions to kernel.h") not being present - Incorrectly assumed that kvm_vm struct members could be directly accessed despite b530eba14c70 ("KVM: selftests: Get rid of kvm_util_internal.h") not being present Backport the first commit, as it is simple enough. Work around the lack of the second commit by using the accessors to get to the kvm_vm struct members. Note that the linux-6.0.y backport of commit 05c2224d4b04 ("KVM: selftests: Fix number of pages for memory slot in memslot_modification_stress_test") is fine because the two prerequisite commits, mentioned above, are both present in v6.0.

[PATCH bpf-next v3 00/16] bpfilter

by Quentin Deslandes

The patchset is based on the patches from David S. Miller [1], Daniel Borkmann [2], and Dmitrii Banshchikov [3]. The main goal of the patchset is to prepare bpfilter for iptables' configuration blob parsing and code generation. The patchset introduces data structures and code for matches, targets, rules and tables. Beside that the code generation is introduced. The first version of the code generation supports only "inline" mode - all chains and their rules emit instructions in linear approach. Things that are not implemented yet: 1) The process of switching from the previous BPF programs to the new set isn't atomic. 2) No support of device ifindex - it's hardcoded 3) No helper subprog for counters update Another problem is using iptables' blobs for tests and filter table initialization. While it saves lines something more maintainable should be done here. The plan for the next iteration: 1) Add a helper program for counters update 2) Handle ifindex Patches 1/2 adds definitions of the used types. Patch 3 adds logging to bpfilter. Patch 4 adds an associative map. Patch 5 add runtime context structure. Patches 6/7 add code generation infrastructure and TC code generator. Patches 8/9/10/11/12 add code for matches, targets, rules and table. Patch 13 adds code generation for table. Patch 14 handles hooked setsockopt(2) calls. Patch 15 adds filter table Patch 16 uses prepared code in main(). Due to poor hardware availability on my side, I've not been able to benchmark those changes. I plan to get some numbers for the next iteration. FORWARD filter chain is now supported, however, it's attached to TC INGRESS along with INPUT filter chain. This is due to XDP not supporting multiple programs to be attached. I could generate a single program out of both INPUT and FORWARD chains, but that would prevent another BPF program to be attached to the interface anyway. If a solution exists to attach both those programs to XDP while allowing for other programs to be attached, it requires more investigation. In the meantime, INPUT and FORWARD filtering is supported using TC. Most of the code in this series was written by Dmitrii Banshchikov, my changes are limited to v3. I've tried to reflect this fact in the commits by adding 'Co-developed-by:' and 'Signed-off-by:' for Dmitrii, please tell me this was done the wrong way. v2 -> v3 Chains: * Add support for FORWARD filter chain. * Add generation of BPF bytecode to assess whether a packet should be forwarded or not, using bpf_fib_lookup(). * Allow for multiple programs to be attached to TC. * Allow for multiple TC hooks to be used. Code generation: * Remove duplicated BPF bytecode generation. * Fix a bug regarding jump offset during generation. * Remove support for XDP from the series, as it's not currently used. Table: * Add new filter_table_update_counters() virtual call. It updates the table's counter stored in the ipt_entry structure. This way, when iptables tries to fetch the values of the counters, bpfilter only has to copy the ipt_entry cached in the table structure. Logging: * Refactor logging primitives. Sockopts: * Add support for userspace counters querying. Rule: * Store the rule's index inside struct rule, to each counters' map usage. v1 -> v2 Maps: * Use map_upsert instead of separate map_insert and map_update Matches: * Add a new virtual call - gen_inline. The call is used for * inline generating of a rule's match. Targets: * Add a new virtual call - gen_inline. The call is used for inline generating of a rule's target. Rules: * Add code generation for rules Table: * Add struct table_ops * Add map for table_ops * Add filter table * Reorganize the way filter table is initialized Sockopts: * Install/uninstall BPF programs while handling IPT_SO_SET_REPLACE Code generation: * Add first version of the code generation Dependencies: * Add libbpf v0 -> v1 IO: * Use ssize_t in pvm_read, pvm_write for total_bytes * Move IO functions into sockopt.c and main.c Logging: * Use LOGLEVEL_EMERG, LOGLEVEL_NOTICE, LOGLEVE_DEBUG while logging to /dev/kmsg * Prepend log message with <n> where n is log level * Conditionally enable BFLOG_DEBUG messages * Merge bflog.{h,c} into context.h Matches: * Reorder fields in struct match_ops for tight packing * Get rid of struct match_ops_map * Rename udp_match_ops to xt_udp * Use XT_ALIGN macro * Store payload size in match size * Move udp match routines into a separate file Targets: * Reorder fields in struct target_ops for tight packing * Get rid of struct target_ops_map * Add comments for convert_verdict function Rules: * Add validation Tables: * Combine table_map and table_list into table_index * Add validation Sockopts: * Handle IPT_SO_GET_REVISION_TARGET 1. https://lore.kernel.org/patchwork/patch/902785/ 2. https://lore.kernel.org/patchwork/patch/902783/ 3. https://kernel.ubuntu.com/~cking/stress-ng/stress-ng.pdf Quentin Deslandes (16): bpfilter: add types for usermode helper tools: add bpfilter usermode helper header bpfilter: add logging facility bpfilter: add map container bpfilter: add runtime context bpfilter: add BPF bytecode generation infrastructure bpfilter: add support for TC bytecode generation bpfilter: add match structure bpfilter: add support for src/dst addr and ports bpfilter: add target structure bpfilter: add rule structure bpfilter: add table structure bpfilter: add table code generation bpfilter: add setsockopt() support bpfilter: add filter table bpfilter: handle setsockopt() calls include/uapi/linux/bpfilter.h | 154 +++ net/bpfilter/Makefile | 16 +- net/bpfilter/codegen.c | 1040 +++++++++++++++++ net/bpfilter/codegen.h | 183 +++ net/bpfilter/context.c | 168 +++ net/bpfilter/context.h | 24 + net/bpfilter/filter-table.c | 344 ++++++ net/bpfilter/filter-table.h | 18 + net/bpfilter/logger.c | 52 + net/bpfilter/logger.h | 80 ++ net/bpfilter/main.c | 132 ++- net/bpfilter/map-common.c | 51 + net/bpfilter/map-common.h | 19 + net/bpfilter/match.c | 55 + net/bpfilter/match.h | 37 + net/bpfilter/rule.c | 286 +++++ net/bpfilter/rule.h | 37 + net/bpfilter/sockopt.c | 533 +++++++++ net/bpfilter/sockopt.h | 15 + net/bpfilter/table.c | 391 +++++++ net/bpfilter/table.h | 59 + net/bpfilter/target.c | 203 ++++ net/bpfilter/target.h | 57 + net/bpfilter/xt_udp.c | 111 ++ tools/include/uapi/linux/bpfilter.h | 175 +++ .../testing/selftests/bpf/bpfilter/.gitignore | 8 + tools/testing/selftests/bpf/bpfilter/Makefile | 57 + .../selftests/bpf/bpfilter/bpfilter_util.h | 80 ++ .../selftests/bpf/bpfilter/test_codegen.c | 338 ++++++ .../testing/selftests/bpf/bpfilter/test_map.c | 63 + .../selftests/bpf/bpfilter/test_match.c | 69 ++ .../selftests/bpf/bpfilter/test_rule.c | 56 + .../selftests/bpf/bpfilter/test_target.c | 83 ++ .../selftests/bpf/bpfilter/test_xt_udp.c | 48 + 34 files changed, 4999 insertions(+), 43 deletions(-) create mode 100644 net/bpfilter/codegen.c create mode 100644 net/bpfilter/codegen.h create mode 100644 net/bpfilter/context.c create mode 100644 net/bpfilter/context.h create mode 100644 net/bpfilter/filter-table.c create mode 100644 net/bpfilter/filter-table.h create mode 100644 net/bpfilter/logger.c create mode 100644 net/bpfilter/logger.h create mode 100644 net/bpfilter/map-common.c create mode 100644 net/bpfilter/map-common.h create mode 100644 net/bpfilter/match.c create mode 100644 net/bpfilter/match.h create mode 100644 net/bpfilter/rule.c create mode 100644 net/bpfilter/rule.h create mode 100644 net/bpfilter/sockopt.c create mode 100644 net/bpfilter/sockopt.h create mode 100644 net/bpfilter/table.c create mode 100644 net/bpfilter/table.h create mode 100644 net/bpfilter/target.c create mode 100644 net/bpfilter/target.h create mode 100644 net/bpfilter/xt_udp.c create mode 100644 tools/include/uapi/linux/bpfilter.h create mode 100644 tools/testing/selftests/bpf/bpfilter/.gitignore create mode 100644 tools/testing/selftests/bpf/bpfilter/Makefile create mode 100644 tools/testing/selftests/bpf/bpfilter/bpfilter_util.h create mode 100644 tools/testing/selftests/bpf/bpfilter/test_codegen.c create mode 100644 tools/testing/selftests/bpf/bpfilter/test_map.c create mode 100644 tools/testing/selftests/bpf/bpfilter/test_match.c create mode 100644 tools/testing/selftests/bpf/bpfilter/test_rule.c create mode 100644 tools/testing/selftests/bpf/bpfilter/test_target.c create mode 100644 tools/testing/selftests/bpf/bpfilter/test_xt_udp.c -- 2.38.1

[V3 PATCH 0/2] Execute hypercalls from guests according to cpu

by Vishal Annapurve

Confidential VMs(CVMs) need to execute hypercall instruction as per the CPU type. Normally KVM emulates the vmcall/vmmcall instruction by patching the guest code at runtime. Such a guest memory manipulation by KVM is not allowed with CVMs. This series adds support of executing hypercall as per the native cpu type queried using cpuid instruction. CPU vendor type is stored after one time execution of cpuid instruction to be reused later. Changes in v3: 1) Guest logic is modified to not rely on host cpu type and instead query cpu vendor using cpuid instruction. 2) Existing callers of vmmcall/vmcall are not updated to avoid enforcing native hypercall instruction across all users which are mostly non-confidential usecases. v2: https://lore.kernel.org/all/20220915000448.1674802-1-vannapurve@google.com/ More discussion around this change: https://lore.kernel.org/lkml/Y1Hhw40H58EmZ6lK@google.com/ Vishal Annapurve (2): KVM: selftests: x86: Cache the cpu vendor type KVM: selftests: x86: Add native hypercall support .../selftests/kvm/include/x86_64/processor.h | 3 ++ .../selftests/kvm/lib/x86_64/processor.c | 51 +++++++++++++++++-- 2 files changed, 49 insertions(+), 5 deletions(-) -- 2.39.0.314.g84b9a713c41-goog

[PATCH v6 0/6] mm/memfd: introduce MFD_NOEXEC_SEAL and MFD_EXEC

by jeffxu＠chromium.org

From: Jeff Xu <jeffxu(a)google.com> Since Linux introduced the memfd feature, memfd have always had their execute bit set, and the memfd_create() syscall doesn't allow setting it differently. However, in a secure by default system, such as ChromeOS, (where all executables should come from the rootfs, which is protected by Verified boot), this executable nature of memfd opens a door for NoExec bypass and enables “confused deputy attack”. E.g, in VRP bug [1]: cros_vm process created a memfd to share the content with an external process, however the memfd is overwritten and used for executing arbitrary code and root escalation. [2] lists more VRP in this kind. On the other hand, executable memfd has its legit use, runc uses memfd’s seal and executable feature to copy the contents of the binary then execute them, for such system, we need a solution to differentiate runc's use of executable memfds and an attacker's [3]. To address those above, this set of patches add following: 1> Let memfd_create() set X bit at creation time. 2> Let memfd to be sealed for modifying X bit. 3> A new pid namespace sysctl: vm.memfd_noexec to control the behavior of X bit.For example, if a container has vm.memfd_noexec=2, then memfd_create() without MFD_NOEXEC_SEAL will be rejected. 4> A new security hook in memfd_create(). This make it possible to a new LSM, which rejects or allows executable memfd based on its security policy. This is V6 version of patch: see [4] [5] [6] [7] for previous versions.
