[PATCH v3 0/8] add UFFDIO_POISON to simulate memory poisoning with UFFD

by Axel Rasmussen

This series adds a new userfaultfd feature, UFFDIO_POISON. See commit 4 for a detailed description of the feature. The series is based on Linus master (partial 6.5 merge window), and structured like this: - Patches 1-3 are preparation / refactoring - Patches 4-6 implement and advertise the new feature - Patches 7-8 implement a unit test for the new feature Changelog: v2 -> v3: - Rebase onto current Linus master. - Don't overwrite existing PTE markers for non-hugetlb UFFDIO_POISON. Before, non-hugetlb would override them, but hugetlb would not. I don't think there's a use case where we *want* to override a UFFD_WP marker for example, so take the more conservative behavior for all kinds of memory. - [Peter] Drop hugetlb mfill atomic refactoring, since it isn't needed for this series (we don't touch that code directly anyway). - [Peter] Switch to re-using PTE_MARKER_SWAPIN_ERROR instead of defining new PTE_MARKER_UFFD_POISON. - [Peter] Extract start / len range overflow check into existing validate_range helper; this fixes the style issue of unnecessary braces in the UFFDIO_POISON implementation, because this code is just deleted. - [Peter] Extract file size check out into a new helper. - [Peter] Defer actually "enabling" the new feature until the last commit in the series; combine this with adding the documentation. As a consequence, move the selftest commits after this one. - [Randy] Fix typo in documentation. v1 -> v2: - [Peter] Return VM_FAULT_HWPOISON not VM_FAULT_SIGBUS, to yield the correct behavior for KVM (guest MCE). - [Peter] Rename UFFDIO_SIGBUS to UFFDIO_POISON. - [Peter] Implement hugetlbfs support for UFFDIO_POISON.

ww_mutex.sh hangs since v5.16-rc1

by Li Zhijian

Hi Folks LKP/0Day found that ww_mutex.sh cannot complete since v5.16-rc1, but I'm pretty sorry that we failed to bisect the FBC, instead, the bisection pointed to a/below merge commit(91e1c99e17) finally. Due to this hang, other tests in the same group are also blocked in 0Day, we hope we can fix this hang ASAP. So if you have any idea about this, or need more debug information, feel free to let me know :) BTW, ww_mutex.sh was failed in v5.15 without hang, and looks it cannot reproduce on a vm.

[RFC][PATCH 00/10] KEYS: Introduce user asymmetric keys and signatures

by Roberto Sassu

From: Roberto Sassu <roberto.sassu(a)huawei.com> Define a new TLV-based format for keys and signatures, aiming to store and use in the kernel the crypto material from other unsupported formats (e.g. PGP). TLV fields have been defined to fill the corresponding kernel structures public_key, public_key_signature and key_preparsed_payload. Keys: struct public_key { struct key_preparsed_payload { KEY_PUB --> void *key; u32 keylen; --> prep->payload.data[asym_crypto] KEY_ALGO --> const char *pkey_algo; KEY_KID0 KEY_KID1 --> prep->payload.data[asym_key_ids] KEY_KID2 KEY_DESC --> prep->description Signatures: struct public_key_signature { SIG_S --> u8 *s; u32 s_size; SIG_KEY_ALGO --> const char *pkey_algo; SIG_HASH_ALGO --> const char *hash_algo; u32 digest_size; SIG_ENC --> const char *encoding; SIG_KID0 SIG_KID1 --> struct asymmetric_key_id *auth_ids[3]; SIG_KID2 For keys, since the format conversion has to be done in user space, user space is assumed to be trusted, in this proposal. Without this assumption, a malicious conversion tool could make a user load to the kernel a different key than the one expected. That should not be a particular problem for keys that are embedded in the kernel image and loaded at boot, since the conversion happens in a trusted environment such as the building infrastructure of the Linux distribution vendor. In the other cases, such as enrolling a key through the Machine Owner Key (MOK) mechanism, the user is responsible to ensure that the crypto material carried in the original format remains the same after the conversion. For signatures, assuming the strength of the crypto algorithms, altering the crypto material is simply a Denial-of-Service (DoS), as data can be validated only with the right signature. This patch set also offers the following contributions: - An API similar to the PKCS#7 one, to verify the authenticity of system data through user asymmetric keys and signatures - A mechanism to store a keyring blob in the kernel image and to extract and load the keys at system boot - eBPF binding, so that data authenticity verification with user asymmetric keys and signatures can be carried out also with eBPF programs - A new command for gnupg (in user space), to convert keys and signatures from PGP to the new kernel format The primary use case for this patch set is to verify the authenticity of RPM package headers with the PGP keys of the Linux distribution. Once their authenticity is verified, file digests can be extracted from those RPM headers and used as reference values for IMA Appraisal. Compared to the previous patch set, the main difference is not relying on User Mode Drivers (UMDs) for the conversion from the original format to the kernel format, due to the concern that full isolation of the UMD process cannot be achieved against a fully privileged system user (root). The discussion is still ongoing here: https://lore.kernel.org/linux-integrity/eb31920bd00e2c921b0aa6ebed8745cb013… This however does not prevent the goal mentioned above of verifying the authenticity of RPM headers to be achieved. The fact that Linux distribution vendors do the conversion in their infrastructure is a good enough guarantee. A very quick way to test the patch set is to execute: # gpg --conv-kernel /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-rawhide-primary | keyctl padd asymmetric "" @u # keyctl show @u Keyring 762357580 --alswrv 0 65534 keyring: _uid.0 567216072 --als--v 0 0 \_ asymmetric: PGP: 18b8e74c Patches 1-2 preliminarly export some definitions to user space so that conversion tools can specify the right public key algorithms and signature encodings (digest algorithms are already exported). Patches 3-5 introduce the user asymmetric keys and signatures. Patches 6 introduces a system API for verifying the authenticity of system data through user asymmetric keys and signatures. Patch 7-8 introduce a mechanism to store a keyring blob with user asymmetric keys in the kernel image, and load them at system boot. Patches 9-10 introduce the eBPF binding and corresponding test (which can be enabled only after the gnupg patches are upstreamed). Patches 1-2 [GNUPG] introduce the new gpg command --conv-kernel to convert PGP keys and signatures to the new kernel format. Changelog v1: - Remove useless check in validate_key() (suggested by Yonghong) - Don't rely on User Mode Drivers for the conversion from the original format to the kernel format - Use the more extensible TLV format, instead of a fixed structure Roberto Sassu (10): crypto: Export public key algorithm information crypto: Export signature encoding information KEYS: asymmetric: Introduce a parser for user asymmetric keys and sigs KEYS: asymmetric: Introduce the user asymmetric key parser KEYS: asymmetric: Introduce the user asymmetric key signature parser verification: Add verify_uasym_signature() and verify_uasym_sig_message() KEYS: asymmetric: Preload user asymmetric keys from a keyring blob KEYS: Introduce load_uasym_keyring() bpf: Introduce bpf_verify_uasym_signature() kfunc selftests/bpf: Prepare a test for user asymmetric key signatures MAINTAINERS | 1 + certs/Kconfig | 11 + certs/Makefile | 7 + certs/system_certificates.S | 18 + certs/system_keyring.c | 166 +++++- crypto/Kconfig | 6 + crypto/Makefile | 2 + crypto/asymmetric_keys/Kconfig | 14 + crypto/asymmetric_keys/Makefile | 10 + crypto/asymmetric_keys/asymmetric_type.c | 3 +- crypto/asymmetric_keys/uasym_key_parser.c | 229 ++++++++ crypto/asymmetric_keys/uasym_key_preload.c | 99 ++++ crypto/asymmetric_keys/uasym_parser.c | 201 +++++++ crypto/asymmetric_keys/uasym_parser.h | 43 ++ crypto/asymmetric_keys/uasym_sig_parser.c | 491 ++++++++++++++++++ crypto/pub_key_info.c | 20 + crypto/sig_enc_info.c | 16 + include/crypto/pub_key_info.h | 15 + include/crypto/sig_enc_info.h | 15 + include/crypto/uasym_keys_sigs.h | 82 +++ include/keys/asymmetric-type.h | 1 + include/linux/verification.h | 50 ++ include/uapi/linux/pub_key_info.h | 22 + include/uapi/linux/sig_enc_info.h | 18 + include/uapi/linux/uasym_parser.h | 107 ++++ kernel/trace/bpf_trace.c | 68 ++- ...y_pkcs7_sig.c => verify_pkcs7_uasym_sig.c} | 159 +++++- ...s7_sig.c => test_verify_pkcs7_uasym_sig.c} | 18 +- .../testing/selftests/bpf/verify_sig_setup.sh | 82 ++- 29 files changed, 1924 insertions(+), 50 deletions(-) create mode 100644 crypto/asymmetric_keys/uasym_key_parser.c create mode 100644 crypto/asymmetric_keys/uasym_key_preload.c create mode 100644 crypto/asymmetric_keys/uasym_parser.c create mode 100644 crypto/asymmetric_keys/uasym_parser.h create mode 100644 crypto/asymmetric_keys/uasym_sig_parser.c create mode 100644 crypto/pub_key_info.c create mode 100644 crypto/sig_enc_info.c create mode 100644 include/crypto/pub_key_info.h create mode 100644 include/crypto/sig_enc_info.h create mode 100644 include/crypto/uasym_keys_sigs.h create mode 100644 include/uapi/linux/pub_key_info.h create mode 100644 include/uapi/linux/sig_enc_info.h create mode 100644 include/uapi/linux/uasym_parser.h rename tools/testing/selftests/bpf/prog_tests/{verify_pkcs7_sig.c => verify_pkcs7_uasym_sig.c} (69%) rename tools/testing/selftests/bpf/progs/{test_verify_pkcs7_sig.c => test_verify_pkcs7_uasym_sig.c} (82%) -- 2.34.1

[RESEND PATCH v3 0/2] RISC-V: mm: Make SV48 the default address space

by Charlie Jenkins

Make sv48 the default address space for mmap as some applications currently depend on this assumption. Also enable users to select desired address space using a non-zero hint address to mmap. Previous kernel changes caused Java and other applications to be broken on sv57 which this patch fixes. Documentation is also added to the RISC-V virtual memory section to explain these changes.

[PATCH bpf-next v2 0/6] Support defragmenting IPv(4|6) packets in BPF

by Daniel Xu

=== Context === In the context of a middlebox, fragmented packets are tricky to handle. The full 5-tuple of a packet is often only available in the first fragment which makes enforcing consistent policy difficult. There are really only two stateless options, neither of which are very nice: 1. Enforce policy on first fragment and accept all subsequent fragments. This works but may let in certain attacks or allow data exfiltration. 2. Enforce policy on first fragment and drop all subsequent fragments. This does not really work b/c some protocols may rely on fragmentation. For example, DNS may rely on oversized UDP packets for large responses. So stateful tracking is the only sane option. RFC 8900 [0] calls this out as well in section 6.3: Middleboxes [...] should process IP fragments in a manner that is consistent with [RFC0791] and [RFC8200]. In many cases, middleboxes must maintain state in order to achieve this goal. === BPF related bits === Policy has traditionally been enforced from XDP/TC hooks. Both hooks run before kernel reassembly facilities. However, with the new BPF_PROG_TYPE_NETFILTER, we can rather easily hook into existing netfilter reassembly infra. The basic idea is we bump a refcnt on the netfilter defrag module and then run the bpf prog after the defrag module runs. This allows bpf progs to transparently see full, reassembled packets. The nice thing about this is that progs don't have to carry around logic to detect fragments. === Changelog === Changes from v1: * Drop bpf_program__attach_netfilter() patches * static -> static const where appropriate * Fix callback assignment order during registration * Only request_module() if callbacks are missing * Fix retval when modprobe fails in userspace * Fix v6 defrag module name (nf_defrag_ipv6_hooks -> nf_defrag_ipv6) * Simplify priority checking code * Add warning if module doesn't assign callbacks in the future * Take refcnt on module while defrag link is active [0]: https://datatracker.ietf.org/doc/html/rfc8900 Daniel Xu (6): netfilter: defrag: Add glue hooks for enabling/disabling defrag netfilter: bpf: Support BPF_F_NETFILTER_IP_DEFRAG in netfilter link netfilter: bpf: Prevent defrag module unload while link active bpf: selftests: Support not connecting client socket bpf: selftests: Support custom type and proto for client sockets bpf: selftests: Add defrag selftests include/linux/netfilter.h | 15 + include/uapi/linux/bpf.h | 5 + net/ipv4/netfilter/nf_defrag_ipv4.c | 17 +- net/ipv6/netfilter/nf_defrag_ipv6_hooks.c | 11 + net/netfilter/core.c | 6 + net/netfilter/nf_bpf_link.c | 149 ++++++++- tools/include/uapi/linux/bpf.h | 5 + tools/testing/selftests/bpf/Makefile | 4 +- .../selftests/bpf/generate_udp_fragments.py | 90 ++++++ .../selftests/bpf/ip_check_defrag_frags.h | 57 ++++ tools/testing/selftests/bpf/network_helpers.c | 26 +- tools/testing/selftests/bpf/network_helpers.h | 3 + .../bpf/prog_tests/ip_check_defrag.c | 282 ++++++++++++++++++ .../selftests/bpf/progs/ip_check_defrag.c | 104 +++++++ 14 files changed, 752 insertions(+), 22 deletions(-) create mode 100755 tools/testing/selftests/bpf/generate_udp_fragments.py create mode 100644 tools/testing/selftests/bpf/ip_check_defrag_frags.h create mode 100644 tools/testing/selftests/bpf/prog_tests/ip_check_defrag.c create mode 100644 tools/testing/selftests/bpf/progs/ip_check_defrag.c -- 2.41.0
