[PATCH 0/3] Improvements to livepatch kselftests on top of kselftest-next

by Marcos Paulo de Souza

The changes doesn't change the current functionality. The changes on lib.mk are both for simplification and also clarification, like in the case of not handling TEST_GEN_MODS_DIR directly. These changes apply on top of the current kselftest-next branch. Please review!

[PATCH RFC] kunit: tool: add 'mte=on' qemu arg on arm64

by Paul Heidekrüger

Hi! I was running some KASan tests with kunit.py recently and noticed that when KASan is run in hw tags mode, we manually have to add the required `mte=on` option to kunit_tool's qemu invocation, as the tests will otherwise crash. To make life easier, I was looking into ways for kunit.py to recognise when MTE support was required and set the option automatically. All solutions I could come up with for having kunit_tool conditionally pass `mte=on` to qemu, either entailed duplicate code or required parsing of kernel's config file again. I was working under the assumption that only after configuring the kernel we would know whether the 'mte=on' option was necessary, as CONFIG_ARM64_MTE is not visible before. Only afterwads did I realise that the qemu arm64 config that kunit_tool falls back on, uses the `virt` machine, which supports MTE in any case. So, could it be as easy as just adding the `mte=on` option to kunit_tool's arm64 config? Would this be a welcome addition? What do you think? Many thanks, Paul Signed-off-by: Paul Heidekrüger <paul.heidekrueger(a)tum.de> --- tools/testing/kunit/qemu_configs/arm64.py | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/testing/kunit/qemu_configs/arm64.py b/tools/testing/kunit/qemu_configs/arm64.py index d3ff27024755..a525f7e1093b 100644 --- a/tools/testing/kunit/qemu_configs/arm64.py +++ b/tools/testing/kunit/qemu_configs/arm64.py @@ -9,4 +9,4 @@ CONFIG_SERIAL_AMBA_PL011_CONSOLE=y''', qemu_arch='aarch64', kernel_path='arch/arm64/boot/Image.gz', kernel_command_line='console=ttyAMA0', - extra_qemu_params=['-machine', 'virt', '-cpu', 'max,pauth-impdef=on']) + extra_qemu_params=['-machine', 'virt,mte=on', '-cpu', 'max,pauth-impdef=on']) -- 2.40.1

[PATCH v5] bpf: Replace bpf_lpm_trie_key 0-length array with flexible array

by Kees Cook

Replace deprecated 0-length array in struct bpf_lpm_trie_key with flexible array. Found with GCC 13: ../kernel/bpf/lpm_trie.c:207:51: warning: array subscript i is outside array bounds of 'const __u8[0]' {aka 'const unsigned char[]'} [-Warray-bounds=] 207 | *(__be16 *)&key->data[i]); | ^~~~~~~~~~~~~ ../include/uapi/linux/swab.h:102:54: note: in definition of macro '__swab16' 102 | #define __swab16(x) (__u16)__builtin_bswap16((__u16)(x)) | ^ ../include/linux/byteorder/generic.h:97:21: note: in expansion of macro '__be16_to_cpu' 97 | #define be16_to_cpu __be16_to_cpu | ^~~~~~~~~~~~~ ../kernel/bpf/lpm_trie.c:206:28: note: in expansion of macro 'be16_to_cpu' 206 | u16 diff = be16_to_cpu(*(__be16 *)&node->data[i] ^ | ^~~~~~~~~~~ In file included from ../include/linux/bpf.h:7: ../include/uapi/linux/bpf.h:82:17: note: while referencing 'data' 82 | __u8 data[0]; /* Arbitrary size */ | ^~~~ And found at run-time under CONFIG_FORTIFY_SOURCE: UBSAN: array-index-out-of-bounds in kernel/bpf/lpm_trie.c:218:49 index 0 is out of range for type '__u8 [*]' Changing struct bpf_lpm_trie_key is difficult since has been used by userspace. For example, in Cilium: struct egress_gw_policy_key { struct bpf_lpm_trie_key lpm_key; __u32 saddr; __u32 daddr; }; While direct references to the "data" member haven't been found, there are static initializers what include the final member. For example, the "{}" here: struct egress_gw_policy_key in_key = { .lpm_key = { 32 + 24, {} }, .saddr = CLIENT_IP, .daddr = EXTERNAL_SVC_IP & 0Xffffff, }; To avoid the build time and run time warnings seen with a 0-sized trailing array for struct bpf_lpm_trie_key, introduce a new struct that correctly uses a flexible array for the trailing bytes, struct bpf_lpm_trie_key_u8. As part of this, include the "header" portion (which is just the "prefixlen" member), so it can be used by anything building a bpf_lpr_trie_key that has trailing members that aren't a u8 flexible array (like the self-test[1]), which is named struct bpf_lpm_trie_key_hdr. Unfortunately, C++ refuses to parse the __struct_group() helper, so it is not possible to define struct bpf_lpm_trie_key_hdr directly in struct bpf_lpm_trie_key_u8, so we must open-code the union directly. Adjust the kernel code to use struct bpf_lpm_trie_key_u8 through-out, and for the selftest to use struct bpf_lpm_trie_key_hdr. Add a comment to the UAPI header directing folks to the two new options.

[PATCH rc 0/8] Add missing cache flush and dirty tracking set for nested parent domain

by Yi Liu

This series adds the missing cache flush and dirty track set for nested parent domain (it's s2_domain but used as parent) which has no insight into devices/DID's under the nested domain (a.k.a s1_domain). This results in missing cache flush per parent domain change and incomplete dirty tracking set on the parent domain. There was a discussion about this in the mailing list [1]. This series adds a s1_domains list in the parent domain to track the nested domains. Hence, the driver can loop the nested domains and use the DIDs of the nested domain to flush iotlb. The driver can also loop the nested domains and nested domain's devices list to flush device iotlb and set the dirty tracking completely. This series doesn't touch the pasid iotlb or the pasid devtlb as there is no support of attaching pasid to nested domain yet. It will be covered when that feature is enabled. The complete code can be found at[2], this has been tested with a hacky Qemu[3] to test the unmap on parent domain and dirty tracking set on parent domain. This just verifies the new path. So appreciated to see t-b with regression tests. This aims to the 6.8 rc#, so your special attention is welcomed.

[RFC PATCH v1 00/28] riscv control-flow integrity for usermode

by debug＠rivosinc.com

From: Deepak Gupta <debug(a)rivosinc.com> It's been almost an year since I posted my last patch series [1] to enable CPU assisted control-flow integrity for usermode on riscv. A lot has changed since then and so has the patches. It's been a while and since this is a reboot of series, starting with RFC and v1. Securing control-flow integrity for usermode requires following - Securing forward control flow : All callsites must reach reach a target that they actually intend to reach. - Securing backward control flow : All function returns must return to location where they were called from. This patch series use riscv cpu extension `zicfilp` [2] to secure forward control flow and `zicfiss` [2] to secure backward control flow. `zicfilp` enforces that all indirect calls or jmps must land on a landing pad instr and label embedded in landing pad instr must match a value programmed in `x7` register (at callsite via compiler). `zicfiss` introduces shadow stack which can only be writeable via shadow stack instructions (sspush and ssamoswap) and thus can't be tampered with via inadvertent stores. More details about extension can be read from [2] and there are details in documentation as well (in this patch series). Using config `CONFIG_RISCV_USER_CFI`, kernel support for riscv control flow integrity for user mode programs can be compiled in the kernel. Enabling of control flow integrity for user programs is left to user runtime (specifically expected from dynamic loader). There has been a lot of earlier discussion on the enabling topic around x86 shadow stack enabling [3, 4, 5] and overall consensus had been to let dynamic loader (or usermode) to decide for enabling the feature. This patch series introduces arch agnostic `prctls` to enable shadow stack and indirect branch tracking. And implements them on riscv. arm64 is expected to implement shadow stack part of these arch agnostic `prctls` [6] Changes since last time *********************** Spec changes ------------ - Forward cfi spec has become much simpler. `lpad` instruction is pseudo for `auipc rd, <20bit_imm>`. `lpad` checks x7 against 20bit embedded in instr. Thus label width is 20bit. - Shadow stack management instructions are reduced to sspush - to push x1/x5 on shadow stack sspopchk - pops from shadow stack and comapres with x1/x5. ssamoswap - atomically swap value on shadow stack. rdssp - reads current shadow stack pointer - Shadow stack accesses on readonly memory always raise AMO/store page fault. `sspopchk` is load but if underlying page is readonly, it'll raise a store page fault. It simplifies hardware and kernel for COW handling for shadow stack pages. - riscv defines a new exception type `software check exception` and control flow violations raise software check exception. - enabling controls for shadow stack and landing are in xenvcfg CSR and controls lower privilege mode enabling. As an example senvcfg controls enabling for U and menvcfg controls enabling for S mode. core mm shadow stack enabling ----------------------------- Shadow stack for x86 usermode are now in mainline and thus this patch series builds on top of that for arch-agnostic mm related changes. Big thanks and shout out to Rick Edgecombe for that. selftests --------- Created some minimal selftests to test the patch series.
