[PATCH] acpi/arm64: check the returned logical CPU number of 'acpi_map_cpuid()'
by Yang Yingliang 22 Sep '20

22 Sep '20

From: Xiongfeng Wang <wangxiongfeng2(a)huawei.com> hulk inclusion category: bugfix bugzilla: NA CVE: NA --------------------------- When we set 'nr_cpus=1' in kernel parameter, we get the following error. It's because 'acpi_map_cpuid()' return -ENODEV in 'acpi_map_cpu()' when there are not enough logical CPU numbers. So we need to check the returned logical CPU number and return error if it is negative.

[PATCH 1/2] random: only read from /dev/random after its pool has received 128 bits
by Yang Yingliang 15 Sep '20

15 Sep '20

From: Theodore Ts'o <tytso(a)mit.edu> mainline inclusion from mainline-v5.2-rc1 commit eb9d1bf079bb438d1a066d72337092935fc770f6 category: bugfix bugzilla: NA CVE: NA https://gitee.com/openeuler/kernel/issues/I1CVQ4?from=project-issue ------------------------------------------------- Immediately after boot, we allow reads from /dev/random before its entropy pool has been fully initialized. Fix this so that we don't allow this until the blocking pool has received 128 bits. We do this by repurposing the initialized flag in the entropy pool struct, and use the initialized flag in the blocking pool to indicate whether it is safe to pull from the blocking pool. To do this, we needed to rework when we decide to push entropy from the input pool to the blocking pool, since the initialized flag for the input pool was used for this purpose. To simplify things, we no longer use the initialized flag for that purpose, nor do we use the entropy_total field any more.

[PATCH] mm: slub: fix conversion of freelist_corrupted()

From: Eugeniu Rosca <erosca(a)de.adit-jv.com> mainline inclusion from mainline-v5.9-rc4 commit dc07a728d49cf025f5da2c31add438d839d076c0 category: bugfix bugzilla: NA CVE: NA ------------------------------------------------- Commit 52f23478081ae0 ("mm/slub.c: fix corrupted freechain in deactivate_slab()") suffered an update when picked up from LKML [1]. Specifically, relocating 'freelist = NULL' into 'freelist_corrupted()' created a no-op statement. Fix it by sticking to the behavior intended in the original patch [1]. In addition, make freelist_corrupted() immune to passing NULL instead of &freelist. The issue has been spotted via static analysis and code review.

[PATCH 0/6] arm64: Initial support for CVADP
by Yang Yingliang 09 Sep '20

09 Sep '20

ARMv8.5 introduces a DC CVADP instruction which cleans the data cache to the point of deep persistence. This series makes the instruction available to userspace and advertises the presence of this CPU feature. At present when CONFIG_ARM64_PMEM is enabled and the CVAP feature is present (ARMv8.2) the CVAP instruction is used (from memcpy_flushcache and arch_wb_cache_pmem). No changes have been made to use CVADP in these functions or similar. As we have moved beyond 32 capabilities we now begin using AT_HWCAP2 for userspace. Tested as follows: $ dmesg | grep "Deep" [ 0.166496] CPU features: detected: Data cache clean to Point of Deep Persistence $ LD_SHOW_AUXV=1 sleep 2>&1 | grep AT_HWCAP AT_HWCAP: ef91ff87 AT_HWCAP2: 0x1 Andrew Murray (6): arm64: HWCAP: add support for AT_HWCAP2 arm64: HWCAP: encapsulate elf_hwcap arm64: Handle trapped DC CVADP arm64: Expose DC CVADP to userspace arm64: add CVADP support to the cache maintenance helper arm64: Advertise ARM64_HAS_DCPODP cpu feature Documentation/arm64/elf_hwcaps.txt | 17 +++- arch/arm64/crypto/aes-ce-ccm-glue.c | 2 +- arch/arm64/crypto/aes-neonbs-glue.c | 2 +- arch/arm64/crypto/chacha20-neon-glue.c | 2 +- arch/arm64/crypto/ghash-ce-glue.c | 6 +- arch/arm64/crypto/sha256-glue.c | 4 +- arch/arm64/include/asm/assembler.h | 4 + arch/arm64/include/asm/cpucaps.h | 3 +- arch/arm64/include/asm/cpufeature.h | 21 ++--- arch/arm64/include/asm/esr.h | 3 +- arch/arm64/include/asm/hwcap.h | 54 +++++++++++- arch/arm64/include/uapi/asm/hwcap.h | 7 +- arch/arm64/kernel/cpufeature.c | 110 +++++++++++++++++-------- arch/arm64/kernel/cpuinfo.c | 3 +- arch/arm64/kernel/fpsimd.c | 4 +- arch/arm64/kernel/traps.c | 3 + drivers/clocksource/arm_arch_timer.c | 8 ++ 17 files changed, 186 insertions(+), 67 deletions(-) -- 2.25.1

BPF 新特性合入openEuler内核策略讨论
by 陆志浩 09 Sep '20

09 Sep '20

Hi： BPF 特性在上游内核社区非常活跃，该特性在网络、内核维护、容器、安全等方面都有使用价值，当前openEuler 4.19内核的BPF特性相较最新版本比较陈旧，不利于下游场景的一些价值场景的业务开发。我希望在openEuler 4.19内核版本逐步合入BPF最新特性，并且长期更新BPF最新特性及bugfix。 PS: 会上提供BPF新特性列表以及相关的文件列表范围，初步给出对周边模块的影响性。 by luzhihao

[PATCH 1/8] posix-cpu-timers: Stop disabling timers on mt-exec
by Yang Yingliang 08 Sep '20

08 Sep '20

From: "Eric W. Biederman" <ebiederm(a)xmission.com> mainline inclusion from mainline-v5.6 commit b95e31c07c5eb4f5c0769f12b38b0343d7961040 category: bugfix bugzilla: 32426 CVE: NA ------------------------ The reasons why the extra posix_cpu_timers_exit_group() invocation has been added are not entirely clear from the commit message. Today all that posix_cpu_timers_exit_group() does is stop timers that are tracking the task from firing. Every other operation on those timers is still allowed. The practical implication of this is posix_cpu_timer_del() which could not get the siglock after the thread group leader has exited (because sighand == NULL) would be able to run successfully because the timer was already dequeued. With that locking issue fixed there is no point in disabling all of the timers. So remove this ``tempoary'' hack.

[PATCH 00/28] ARMv8.3 pointer authentication
by Yang Yingliang 02 Sep '20

02 Sep '20

Firstly, this series improves function return address protection for the arm64 kernel, by compiling the kernel with ARMv8.3 Pointer Authentication instructions (referred ptrauth hereafter). This should help protect the kernel against attacks using return-oriented programming. Secondly, Suzuki's patches optimize checking and enabling cpu capabilities. Thirdly, three patches on kernel config enable ptrauth compiling and fix compile warnings. Finally, two patches of Mark Rutland and one patch of Marc Zyngier are necessary simplifications and cleanups.

[PATCH] delete python2 dependency
by Zhipeng Xie 01 Sep '20

01 Sep '20

Python2 is no longer supported by the upstream community. The dependency on python2 should be removed from the kernel code.

[PATCH 1/4] can: j1939: fix support for multipacket broadcast message
by Yang Yingliang 25 Aug '20

25 Aug '20

From: Zhang Changzhong <zhangchangzhong(a)huawei.com> mainline inclusion from mainline-v5.9-rc2 commit f4fd77fd87e9b214c26bb2ebd4f90055eaea5ade category: bugfix bugzilla: 39990 CVE: NA --------------------------- Currently j1939_tp_im_involved_anydir() in j1939_tp_recv() check the previously set flags J1939_ECU_LOCAL_DST and J1939_ECU_LOCAL_SRC of incoming skb, thus multipacket broadcast message was aborted by receive side because it may come from remote ECUs and have no exact dst address. Similarly, j1939_tp_cmd_recv() and j1939_xtp_rx_dat() didn't process broadcast message. So fix it by checking and process broadcast message in j1939_tp_recv(), j1939_tp_cmd_recv() and j1939_xtp_rx_dat().

[RESEND,PATCH 0/7] Improvements and fixes
by Roberto Sassu 25 Aug '20

25 Aug '20

Resending due to conflicts with existing code. This patch set provides some improvements and fixes. The first three patches solve a permission problem caused by EVM. EVM denies xattr operations also for files that are not appraised by IMA. If only executables are appraised, xattr operations on the other files should be allowed, even if metadata verification fails (for example due to missing security.evm). At the moment, in openEuler we use EVM_ALLOW_METADATA_WRITES to avoid this problem (EVM does not check metadata integrity), but it would be useful to do the verification for example to prevent accidental changes on immutable metadata. The fourth patch enables the choice of the algorithm for the HMAC and ensures that the parameters passed to the functions which handle the HMAC are consistent with the algorithm chosen. The last three patches are simple bug fixes. Roberto Sassu (7): evm: Move hooks outside LSM infrastructure evm: Extend API of post hooks to pass the result of pre hooks evm: Return -EAGAIN to ignore verification failures evm: Propagate choice of HMAC algorithm in evm_crypto.c ima: Fix datalen check in ima_write_data() evm: Fix validation of fake xattr passed by IMA evm: Initialize saved_evm_status fs/attr.c | 7 ++- fs/xattr.c | 65 +++++++++++++++++--------- include/linux/evm.h | 18 +++++--- security/integrity/evm/Kconfig | 32 +++++++++++++ security/integrity/evm/evm.h | 1 + security/integrity/evm/evm_crypto.c | 15 ++++-- security/integrity/evm/evm_main.c | 71 +++++++++++++++++++++-------- security/integrity/ima/ima_fs.c | 2 +- security/integrity/integrity.h | 2 +- security/security.c | 18 ++------ 10 files changed, 159 insertions(+), 72 deletions(-) -- 2.27.GIT
