perf spe-c2c record失败的问题
by haoxin 15 Dec '21

15 Dec '21

您好，我采用最细的openEuler-1.0测试perf spe-c2c的功能，但是发现/sys/devices下没有arm_spe_0这个目录执行perf spe-c2c record时显示： event syntax error: 'arm_spe_0/ts_enable=1,pct_enable=1,pa_enable=1,load_filter=1,jitter=1,store_filter=1,min_latency=0/' \___ Cannot find PMU `arm_spe_0'. Missing kernel support? 想问下您这是为什么？需要哪里开启spe功能吗？

[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

[PATCH 0/4] kvm: arm64: emulate ID registers
by Yang Yingliang 25 Aug '20

In AArch64, guest will read the same values of the ID regsiters with host. Both of them read the values from arm64_ftr_regs. This patch series add support to emulate and configure ID registers so that we can control the value of ID registers that guest read.

[PATCH 01/22] arm64: mm: define NET_IP_ALIGN to 0
by Yang Yingliang 25 Aug '20

25 Aug '20

From: Ard Biesheuvel <ard.biesheuvel(a)linaro.org> mainline inclusion from mainline-v4.20-rc2 commit 26a4676faa1ad5d99317e0cd701e5d6f3e716b77 category: feature bugzilla: NA CVE: NA --------------------------- On arm64, there is no need to add 2 bytes of padding to the start of each network buffer just to make the IP header appear 32-bit aligned. Since this might actually adversely affect DMA performance some platforms, let's override NET_IP_ALIGN to 0 to get rid of this padding.

We do not have a plan to support ARM32 at this point, and it would be great if you could help to do it. IMHO, the patches merged into the openEuler kernel do not break the support for ARM32. So, select a proper config would be helpful for building on arm32 platform. > > Looking for your rely. > > _______________________________________________ > Dev mailing list -- dev(a)openeuler.org > To unsubscribe send an email to dev-leave(a)openeuler.org >
