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] net: hns3: fix ping failed after S3 since removing HNAE3_RESTORE_CLIENT
by Yonglong Liu 09 Sep '20

09 Sep '20

commit: 412c29318f9b ("net: hns3: refactor the MAC address configure") removed the operation of HNAE3_RESTORE_CLIENT, so after S3 or S4, the MAC address is missing, then cause ping failed.

[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. Amit Daniel Kachhap (9): arm64: cpufeature: Fix meta-capability cpufeature check arm64: ptrauth: Add bootup/runtime flags for __cpu_setup arm64: cpufeature: Move cpu capability helpers inside C file arm64: initialize ptrauth keys for kernel booting task arm64: mask PAC bits of __builtin_return_address arm64: __show_regs: strip PAC from lr in printk arm64: suspend: restore the kernel ptrauth keys lkdtm: arm64: test kernel pointer authentication arm64: Kconfig: ptrauth: Add binutils version check to fix mismatch Catalin Marinas (1): kbuild: Add support for 'as-instr' to be used in Kconfig files Kristina Martsenko (7): arm64: cpufeature: add pointer auth meta-capabilities arm64: rename ptrauth key structures to be user-specific arm64: install user ptrauth keys at kernel exit time arm64: cpufeature: handle conflicts based on capability arm64: enable ptrauth earlier arm64: initialize and switch ptrauth kernel keys arm64: compile the kernel with ptrauth return address signing Marc Zyngier (1): arm64: Drop unnecessary include from asm/smp.h Mark Rutland (3): arm64: unwind: strip PAC from kernel addresses arm64: remove ptrauth_keys_install_kernel sync arg arm64: simplify ptrauth initialization Nick Desaulniers (1): arm64: Kconfig: verify binutils support for ARM64_PTR_AUTH Suzuki K Poulose (4): arm64: capabilities: Speed up capability lookup arm64: capabilities: Optimize this_cpu_has_cap arm64: capabilities: Use linear array for detection and verification arm64: capabilities: Batch cpu_enable callbacks Vincenzo Frascino (1): kconfig: Add support for 'as-option' Zheng Zengkai (1): config: enable ARM64 pointer authentication configs by default arch/arm64/Kconfig | 38 +++- arch/arm64/Makefile | 11 + arch/arm64/configs/hulk_defconfig | 7 + arch/arm64/configs/openeuler_defconfig | 7 + arch/arm64/include/asm/asm_pointer_auth.h | 98 ++++++++ arch/arm64/include/asm/compiler.h | 19 ++ arch/arm64/include/asm/cpucaps.h | 4 +- arch/arm64/include/asm/cpufeature.h | 42 ++-- arch/arm64/include/asm/pointer_auth.h | 50 ++--- arch/arm64/include/asm/processor.h | 3 +- arch/arm64/include/asm/stackprotector.h | 5 + arch/arm64/kernel/asm-offsets.c | 13 ++ arch/arm64/kernel/cpufeature.c | 258 ++++++++++++++-------- arch/arm64/kernel/entry.S | 6 + arch/arm64/kernel/head.S | 10 + arch/arm64/kernel/pointer_auth.c | 7 +- arch/arm64/kernel/process.c | 5 +- arch/arm64/kernel/ptrace.c | 16 +- arch/arm64/kernel/sleep.S | 1 + arch/arm64/kernel/stacktrace.c | 5 +- arch/arm64/mm/proc.S | 27 ++- drivers/misc/lkdtm/bugs.c | 36 +++ drivers/misc/lkdtm/core.c | 1 + drivers/misc/lkdtm/lkdtm.h | 1 + include/linux/stackprotector.h | 2 +- scripts/Kconfig.include | 10 + 26 files changed, 513 insertions(+), 169 deletions(-) create mode 100644 arch/arm64/include/asm/asm_pointer_auth.h -- 2.25.1

[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 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 >

[PATCH,V2,kernel-4.19 1/2] kexec: Add quick kexec support for kernel
by Sang Yan 18 Aug '20

18 Aug '20

euleros inclusion category: feature bugzilla: NA issues: #I1RC8Z CVE: NA In normal kexec, relocating kernel may cost 5 ~ 10 seconds, to copy all segments from vmalloced memory to kernel boot memory, because of disabled mmu. We introduce quick kexec to save time of copying memory as above, just like kdump(kexec on crash), by using reserved memory "Quick Kexec". Constructing quick kimage as the same as crash kernel, then simply copy all segments of kimage to reserved memroy. We also add this support in syscall kexec_load using flags of KEXEC_QUICK.

[PATCH kernel-4.19 1/2] kexec: Add quick kexec support for kernel
by Sang Yan 13 Aug '20

13 Aug '20

[PATCH 0/7] Improvements and fixes
by Roberto Sassu 07 Aug '20

07 Aug '20

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 | 64 +++++++++++++++++--------- 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, 158 insertions(+), 72 deletions(-) -- 2.27.GIT

[PATCH 01/23] ima: Use buffer large enough to store fake IMA xattr for appraisal
by Roberto Sassu 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 1/5] cgroup: memcg: net: do not associate sock with unrelated cgroup
by Yang Yingliang 04 Aug '20

04 Aug '20

From: Shakeel Butt <shakeelb(a)google.com> [ Upstream commit e876ecc67db80dfdb8e237f71e5b43bb88ae549c ] We are testing network memory accounting in our setup and noticed inconsistent network memory usage and often unrelated cgroups network usage correlates with testing workload. On further inspection, it seems like mem_cgroup_sk_alloc() and cgroup_sk_alloc() are broken in irq context specially for cgroup v1. mem_cgroup_sk_alloc() and cgroup_sk_alloc() can be called in irq context and kind of assumes that this can only happen from sk_clone_lock() and the source sock object has already associated cgroup. However in cgroup v1, where network memory accounting is opt-in, the source sock can be unassociated with any cgroup and the new cloned sock can get associated with unrelated interrupted cgroup. Cgroup v2 can also suffer if the source sock object was created by process in the root cgroup or if sk_alloc() is called in irq context. The fix is to just do nothing in interrupt.

[PATCH] netfilter: nat: check the bounds of nf_nat_l3protos and nf_nat_l4protos

hulk inclusion category: bugfix bugzilla: NA CVE: NA ------------------------------------------------- famliy can be passed from user space and will be out of range of nf_nat_l3protos or nf_nat_l4protos, so we need check the family when call __nf_nat_l3proto_find() or __nf_nat_l4proto_find(). nfnetlink_parse_nat_setup() need return EAGAIN, if __nf_nat_l3proto_find() returns null, so we return a error number to distinguish this case.

[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

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.

[PATCH] scsi: qedf: remove memset/memcpy to nfunc and use func instead

[PATCH 0/5] Adding Huawei BMA driver
by yunaixin03610＠163.com 10 Jul '20

10 Jul '20

From: Naixin Yu <yunaixin(a)huawei.com> This patch set contains 5 communication drivers for Huawei BMA software. The BMA software is a system management software. It supports the status monitoring, performance monitoring, and event monitoring of various components, including server CPUs, memory, hard disks, NICs, IB cards, PCIe cards, RAID controller cards, and optical modules. These 5 drivers are used to send/receive message through PCIe channel in different ways by BMA software.

For now it's only member is "struct can_dev_rcv_lists". The CAN midlayer private is allocated via alloc_netdev()'s private and assigned to "struct net_device::ml_priv" during device creation. This is done transparently for CAN drivers using alloc_candev(). The slcan, vcan and vxcan drivers which are not using alloc_candev() have been adopted manually. The memory layout of the netdev_priv allocated via alloc_candev() will looke like this: +-------------------------+ | driver's priv | +-------------------------+ | struct can_ml_priv | +-------------------------+ | array of struct sk_buff | +-------------------------+ Signed-off-by: Oleksij Rempel <o.rempel(a)pengutronix.de> Signed-off-by: Oliver Hartkopp <socketcan(a)hartkopp.net> Signed-off-by: Marc Kleine-Budde <mkl(a)pengutronix.de> Signed-off-by: Zhang Changzhong <zhangchangzhong(a)huawei.com> Reviewed-by: YueHaibing <yuehaibing(a)huawei.com> Signed-off-by: Yang Yingliang <yangyingliang(a)huawei.com> --- drivers/net/can/dev.c | 22 ++++++++++--- drivers/net/can/slcan.c | 5 ++- drivers/net/can/vcan.c | 6 ++-- drivers/net/can/vxcan.c | 3 +- include/linux/can/can-ml.h | 66 ++++++++++++++++++++++++++++++++++++++ net/can/af_can.c | 1 + net/can/af_can.h | 15 --------- net/can/proc.c | 1 + 8 files changed, 96 insertions(+), 23 deletions(-) create mode 100644 include/linux/can/can-ml.h diff --git a/drivers/net/can/dev.c b/drivers/net/can/dev.c index 1545f2b299d0..1723c848d0c4 100644 --- a/drivers/net/can/dev.c +++ b/drivers/net/can/dev.c @@ -23,6 +23,7 @@ #include <linux/if_arp.h> #include <linux/workqueue.h> #include <linux/can.h> +#include <linux/can/can-ml.h> #include <linux/can/dev.h> #include <linux/can/skb.h> #include <linux/can/netlink.h> @@ -729,11 +730,24 @@ struct net_device *alloc_candev_mqs(int sizeof_priv, unsigned int echo_skb_max, struct can_priv *priv; int size; + /* We put the driver's priv, the CAN mid layer priv and the + * echo skb into the netdevice's priv.

When --mss=XXX option is set, packetdrill always provide gso_type & gso_size for its inbound packets, regardless of packet size. if (packet->tcp && packet->mss) { if (packet->ipv4) gso.gso_type = VIRTIO_NET_HDR_GSO_TCPV4; else gso.gso_type = VIRTIO_NET_HDR_GSO_TCPV6; gso.gso_size = packet->mss; } Since many other programs could do the same, relax virtio_net_hdr_to_skb() to no longer return an error, but instead ignore gso settings. This keeps Willem intent to make sure no malicious packet could reach gso stack. Note that TCP stack has a special logic in tcp_set_skb_tso_segs() to clear gso_size for small packets.

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

06 Jul '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] perf top: Fix stdio interface input handling with glibc 2.28+

From: Tommi Rantala <tommi.t.rantala(a)nokia.com> mainline inclusion from mainline-5.6-rc6 commit 29b4f5f18857 category: bugfix bugzilla: 31774 CVE: NA ------------------------------------------------- Since glibc 2.28 when running 'perf top --stdio', input handling no longer works, but hitting any key always just prints the "Mapped keys" help text. To fix it, call clearerr() in the display_thread() loop to clear any EOF sticky errors, as instructed in the glibc NEWS file (https://sourceware.org/git/?p=glibc.git;a=blob;f=NEWS) * All stdio functions now treat end-of-file as a sticky condition. If you read from a file until EOF, and then the file is enlarged by another process, you must call clearerr or another function with the same effect (e.g. fseek, rewind) before you can read the additional data. This corrects a longstanding C99 conformance bug. It is most likely to affect programs that use stdio to read interactive input from a terminal. (Bug #1190.)

This leads to an unintended difference between PF and VF in hand-off state to the user. We can correct this by setting the initial value of the memory enable bit in our virtualized config space. There's really no need however to ever fault a user on a VF though as this would only indicate an error in the user's management of the enable bit, versus a PF where the same access could trigger hardware faults.

[PATCH] Disable cache readunique on 1620 which can cause performance decrease
by shenkai (D) 28 Jun '20

From 85f6f7c3bd13b3d6fd064899e2818ee70bdf29e2 Mon Sep 17 00:00:00 2001 euleros inclusion commit 85f6f7c3bd13b3d6fd064899e2818ee70bdf29e2 category: bugfix Random performance decreases appear on cases of Hackbench which test pipe or socket communication among multi-threads on Hisi 1620 SoC. Cache sharing which caused by the change of the data layout and the cache readunique mechanism both lead to this problem. Readunique mechanism which may caused by store operation will invalid cachelines on other cores during data fetching stage which can cause cacheline invalidation happens frequently in a sharing data access situation. Disable cache readunique can trackle this problem. Test cases are like: ./hackbench -pipe 20 thread 1000 On 128 cores 1620 machine, the time cost of above test cases is basicly 0.3s when RU is off while when RU is on the time cost can be over 1s. What's more, we disble readunique only in el2 for in el1 disabling readunique may cause panic due to lack of related priority which often be set in BIOS.

[PATCH 1/8] ovl: fix lookup failure on multi lower squashfs
by Yang Yingliang 24 Jun '20

24 Jun '20

From: Amir Goldstein <amir73il(a)gmail.com> mainline inclusion from mainline-5.5-rc2 commit 7e63c87fc2dcf3be9d3aab82d4a0ea085880bdca category: bugfix bugzilla: 37632 CVE: NA --------------------------- In the past, overlayfs required that lower fs have non null uuid in order to support nfs export and decode copy up origin file handles. Commit 9df085f3c9a2 ("ovl: relax requirement for non null uuid of lower fs") relaxed this requirement for nfs export support, as long as uuid (even if null) is unique among all lower fs. However, said commit unintentionally also relaxed the non null uuid requirement for decoding copy up origin file handles, regardless of the unique uuid requirement. Amend this mistake by disabling decoding of copy up origin file handle from lower fs with a conflicting uuid. We still encode copy up origin file handles from those fs, because file handles like those already exist in the wild and because they might provide useful information in the future. There is an unhandled corner case described by Miklos this way: - two filesystems, A and B, both have null uuid - upper layer is on A - lower layer 1 is also on A - lower layer 2 is on B In this case bad_uuid won't be set for B, because the check only involves the list of lower fs. Hence we'll try to decode a layer 2 origin on layer 1 and fail. We will deal with this corner case later.
