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 01/23] ima: Use buffer large enough to store fake IMA xattr for appraisal
by Roberto Sassu 06 Aug '20

06 Aug '20

hulk inclusion category: feature feature: digest-lists --------------------------- A fake IMA xattr is created to perform EVM verification even if security.ima is not present. Appraisal could succeed if EVM status is unknown and the file digest is found in a digest list. This patch allocates a larger buffer to store fake IMA xattrs (struct evm_ima_xattr_data can be used only for SHA1 digests).

[PATCH 01/35] selinux: allow labeling before policy is loaded
by Roberto Sassu 06 Aug '20

06 Aug '20

From: Jonathan Lebon <jlebon(a)redhat.com> mainline inclusion from mainline-v5.5-rc1 commit 3e3e24b42043eceb97ed834102c2d094dfd7aaa6 category: bugfix --------------------------- Currently, the SELinux LSM prevents one from setting the `security.selinux` xattr on an inode without a policy first being loaded. However, this restriction is problematic: it makes it impossible to have newly created files with the correct label before actually loading the policy. This is relevant in distributions like Fedora, where the policy is loaded by systemd shortly after pivoting out of the initrd. In such instances, all files created prior to pivoting will be unlabeled. One then has to relabel them after pivoting, an operation which inherently races with other processes trying to access those same files. Going further, there are use cases for creating the entire root filesystem on first boot from the initrd (e.g. Container Linux supports this today[1], and we'd like to support it in Fedora CoreOS as well[2]). One can imagine doing this in two ways: at the block device level (e.g. laying down a disk image), or at the filesystem level. In the former, labeling can simply be part of the image. But even in the latter scenario, one still really wants to be able to set the right labels when populating the new filesystem. This patch enables this by changing behaviour in the following two ways: 1. allow `setxattr` on mounts without `SBLABEL_MNT` (which is all of them if no policy is loaded yet) 2. don't try to set the in-core inode SID if we're not initialized; instead leave it as `LABEL_INVALID` so that revalidation may be attempted at a later time Note the first hunk of this patch is functionally the same as a previously discussed one[3], though it was part of a larger series which wasn't accepted.

[PATCH 1/3] arm64: Add support for SB barrier and patch in over DSB; ISB sequences
by Yang Yingliang 29 Jul '20

29 Jul '20

From: Will Deacon <will.deacon(a)arm.com> mainline inclusion from v5.0-rc1 commit bd4fb6d270bc423a9a4098108784f7f9254c4e6d category: feature bugzilla: 30102 CVE: NA ------------------------------------------------- We currently use a DSB; ISB sequence to inhibit speculation in set_fs(). Whilst this works for current CPUs, future CPUs may implement a new SB barrier instruction which acts as an architected speculation barrier. On CPUs that support it, patch in an SB; NOP sequence over the DSB; ISB sequence and advertise the presence of the new instruction to userspace.

[PATCH] kernel/notifier.c: intercept duplicate registrations to avoid infinite loops
by Yang Yingliang 29 Jul '20

29 Jul '20

From: Xiaoming Ni <nixiaoming(a)huawei.com> mainline inclusion from mainline-v5.5-rc1 commit 1a50cb80f219c44adb6265f5071b81fc3c1deced category: bugfix bugzilla: NA CVE: NA --------------------------------------------- [ Upstream commit 1a50cb80f219c44adb6265f5071b81fc3c1deced ] Registering the same notifier to a hook repeatedly can cause the hook list to form a ring or lose other members of the list. case1: An infinite loop in notifier_chain_register() can cause soft lockup atomic_notifier_chain_register(&test_notifier_list, &test1); atomic_notifier_chain_register(&test_notifier_list, &test1); atomic_notifier_chain_register(&test_notifier_list, &test2); case2: An infinite loop in notifier_chain_register() can cause soft lockup atomic_notifier_chain_register(&test_notifier_list, &test1); atomic_notifier_chain_register(&test_notifier_list, &test1); atomic_notifier_call_chain(&test_notifier_list, 0, NULL); case3: lose other hook test2 atomic_notifier_chain_register(&test_notifier_list, &test1); atomic_notifier_chain_register(&test_notifier_list, &test2); atomic_notifier_chain_register(&test_notifier_list, &test1); case4: Unregister returns 0, but the hook is still in the linked list, and it is not really registered. If you call notifier_call_chain after ko is unloaded, it will trigger oops. If the system is configured with softlockup_panic and the same hook is repeatedly registered on the panic_notifier_list, it will cause a loop panic.

[PATCH 001/132] net: rmnet: fix lower interface leak
by Yang Yingliang 24 Jul '20

24 Jul '20

From: Taehee Yoo <ap420073(a)gmail.com> commit 2a762e9e8cd1cf1242e4269a2244666ed02eecd1 upstream. There are two types of the lower interface of rmnet that are VND and BRIDGE. Each lower interface can have only one type either VND or BRIDGE. But, there is a case, which uses both lower interface types. Due to this unexpected behavior, lower interface leak occurs. Test commands: ip link add dummy0 type dummy ip link add dummy1 type dummy ip link add rmnet0 link dummy0 type rmnet mux_id 1 ip link set dummy1 master rmnet0 ip link add rmnet1 link dummy1 type rmnet mux_id 2 ip link del rmnet0 The dummy1 was attached as BRIDGE interface of rmnet0.

[PATCH] scsi: qedf: remove memset/memcpy to nfunc and use func instead
by Yang Yingliang 24 Jul '20

24 Jul '20

From: Colin Ian King <colin.king(a)canonical.com> mainline inclusion from mainline-v5.2-rc3 commit 65b1dc99008de592f7c1c8e5fad446824791b4da category: bugfix bugzilla: NA CVE: NA ------------------------------------------------- Currently the qedf_dbg_* family of functions can overrun the end of the source string if it is less than the destination buffer length because of the use of a fixed sized memcpy. Remove the memset/memcpy calls to nfunc and just use func instead as it is always a null terminated string.
