[PATCH 01/20] nvme-rdma: remove redundant reference between ib_device and tagset
by Yang Yingliang 22 Oct '20

22 Oct '20

From: Max Gurtovoy <maxg(a)mellanox.com> mainline inclusion from mainline-v5.2-rc1 commit 87fd125344d68adf7699ec7396aa9f905ce79a80 category: bugfix bugzilla: NA CVE: NA Link: https://gitee.com/openeuler/kernel/issues/I1WGZE ------------------------------------------------- In the past, before adding f41725bb ("nvme-rdma: Use mr pool") commit, we needed a reference on the ib_device as long as the tagset was alive, as the MRs in the request structures needed a valid ib_device. Now, we allocate/deallocate MR pool per QP and consume on demand. Also remove nvme_rdma_free_tagset function and use blk_mq_free_tag_set instead, as it unneeded anymore. This commit also fixes a memory leakage and possible segmentation fault. When configuring the system with NIC teaming (aka bonding), we use 1 network interface to create an HA connection to the target side. In case one connection breaks down, nvme-rdma driver will get notification from rdma-cm layer that underlying address was change and will start error recovery process. During this process, we'll reconnect to the target via the second interface in the bond without destroying the tagset. This will cause a leakage of the initial rdma device (ndev) and miscount in the reference count of the new created rdma device (new ndev). In the final destruction (or in another error flow), we'll get a warning dump from the ib_dealloc_pd that we still have inflight MR's related to that pd. This happens becasue of the miscount of the reference tag of the rdma device and causing access violation to it's elements (some queues are not destroyed yet).

[PATCH] perf/core: Fix race in the perf_mmap_close() function
by Yang Yingliang 16 Oct '20

16 Oct '20

From: Jiri Olsa <jolsa(a)redhat.com> mainline inclusion from mainline-v5.10 commit f91072ed1b7283b13ca57fcfbece5a3b92726143 category: bugfix bugzilla: NA CVE: CVE-2020-14351 -------------------------------- There's a possible race in perf_mmap_close() when checking ring buffer's mmap_count refcount value. The problem is that the mmap_count check is not atomic because we call atomic_dec() and atomic_read() separately. perf_mmap_close: ... atomic_dec(&rb->mmap_count); ... if (atomic_read(&rb->mmap_count)) goto out_put; <ring buffer detach> free_uid out_put: ring_buffer_put(rb); /* could be last */ The race can happen when we have two (or more) events sharing same ring buffer and they go through atomic_dec() and then they both see 0 as refcount value later in atomic_read(). Then both will go on and execute code which is meant to be run just once. The code that detaches ring buffer is probably fine to be executed more than once, but the problem is in calling free_uid(), which will later on demonstrate in related crashes and refcount warnings, like: refcount_t: addition on 0; use-after-free. ...

[PATCH] geneve: add transport ports in route lookup for geneve
by Yang Yingliang 15 Oct '20

15 Oct '20

From: Mark Gray <mark.d.gray(a)redhat.com> stable inclusion from linux-4.19.148 commit c797110d97c48054d1491251fd713900ff51615c CVE: CVE-2020-25645 -------------------------------- [ Upstream commit 34beb21594519ce64a55a498c2fe7d567bc1ca20 ] This patch adds transport ports information for route lookup so that IPsec can select Geneve tunnel traffic to do encryption. This is needed for OVS/OVN IPsec with encrypted Geneve tunnels. This can be tested by configuring a host-host VPN using an IKE daemon and specifying port numbers. For example, for an Openswan-type configuration, the following parameters should be configured on both hosts and IPsec set up as-per normal: $ cat /etc/ipsec.conf conn in ... left=$IP1 right=$IP2 ... leftprotoport=udp/6081 rightprotoport=udp ... conn out ... left=$IP1 right=$IP2 ... leftprotoport=udp rightprotoport=udp/6081 ... The tunnel can then be setup using "ip" on both hosts (but changing the relevant IP addresses): $ ip link add tun type geneve id 1000 remote $IP2 $ ip addr add 192.168.0.1/24 dev tun $ ip link set tun up This can then be tested by pinging from $IP1: $ ping 192.168.0.2 Without this patch the traffic is unencrypted on the wire.

[PATCH 01/11] xfs: Fix tail rounding in xfs_alloc_file_space()
by Yang Yingliang 15 Oct '20

15 Oct '20

From: Max Reitz <mreitz(a)redhat.com> mainline inclusion from mainline-v5.4-rc3 commit e093c4be760ebf46c131ae0dd6138865a22f46fa category: bugfix bugzilla: NA CVE: NA --------------------------- To ensure that all blocks touched by the range [offset, offset + count) are allocated, we need to calculate the block count from the difference of the range end (rounded up) and the range start (rounded down). Before this patch, we just round up the byte count, which may lead to unaligned ranges not being fully allocated: $ touch test_file $ block_size=$(stat -fc '%S' test_file) $ fallocate -o $((block_size / 2)) -l $block_size test_file $ xfs_bmap test_file test_file: 0: [0..7]: 1396264..1396271 1: [8..15]: hole There should not be a hole there. Instead, the first two blocks should be fully allocated. With this patch applied, the result is something like this: $ touch test_file $ block_size=$(stat -fc '%S' test_file) $ fallocate -o $((block_size / 2)) -l $block_size test_file $ xfs_bmap test_file test_file: 0: [0..15]: 11024..11039 Signed-off-by: Max Reitz <mreitz(a)redhat.com> Reviewed-by: Carlos Maiolino <cmaiolino(a)redhat.com> Reviewed-by: Christoph Hellwig <hch(a)lst.de> Reviewed-by: Darrick J.

[PATCH 1/6] blk-mq: insert passthrough request into hctx->dispatch directly
by Yang Yingliang 13 Oct '20

13 Oct '20

From: Ming Lei <ming.lei(a)redhat.com> mainline inclusion from mainline-5.6-rc4 commit 01e99aeca3979600302913cef3f89076786f32c8 category: bugfix bugzilla: 42777 CVE: NA --------------------------- For some reason, device may be in one situation which can't handle FS request, so STS_RESOURCE is always returned and the FS request will be added to hctx->dispatch. However passthrough request may be required at that time for fixing the problem. If passthrough request is added to scheduler queue, there isn't any chance for blk-mq to dispatch it given we prioritize requests in hctx->dispatch. Then the FS IO request may never be completed, and IO hang is caused. So passthrough request has to be added to hctx->dispatch directly for fixing the IO hang. Fix this issue by inserting passthrough request into hctx->dispatch directly together withing adding FS request to the tail of hctx->dispatch in blk_mq_dispatch_rq_list(). Actually we add FS request to tail of hctx->dispatch at default, see blk_mq_request_bypass_insert(). Then it becomes consistent with original legacy IO request path, in which passthrough request is always added to q->queue_head.

[PATCH] hdlc_ppp: add range checks in ppp_cp_parse_cr()

From: Dan Carpenter <dan.carpenter(a)oracle.com> stable inclusion from linux-4.19.148 commit 45676c0bc28eff8f46455b28e2db80a77676488b CVE: CVE-2020-25643 -------------------------------- [ Upstream commit 66d42ed8b25b64eb63111a2b8582c5afc8bf1105 ] There are a couple bugs here: 1) If opt[1] is zero then this results in a forever loop. If the value is less than 2 then it is invalid. 2) It assumes that "len" is more than sizeof(valid_accm) or 6 which can result in memory corruption. In the case of LCP_OPTION_ACCM, then we should check "opt[1]" instead of "len" because, if "opt[1]" is less than sizeof(valid_accm) then "nak_len" gets out of sync and it can lead to memory corruption in the next iterations through the loop. In case of LCP_OPTION_MAGIC, the only valid value for opt[1] is 6, but the code is trying to log invalid data so we should only discard the data when "len" is less than 6 because that leads to a read overflow.

[PATCH 01/65] mm: memcg: make memory.oom.group tolerable to task migration
by Yang Yingliang 10 Oct '20

10 Oct '20

From: Roman Gushchin <guro(a)fb.com> mainline inclusion from mainline-5.7-rc1 commit 48fe267c503ec22014ba4e83d002b07caad034d0 category: bugfix bugzilla: 33351 CVE: NA ------------------------------------------------- If a task is getting moved out of the OOMing cgroup, it might result in unexpected OOM killings if memory.oom.group is used anywhere in the cgroup tree. Imagine the following example: A (oom.group = 1) / \ (OOM) B C Let's say B's memory.max is exceeded and it's OOMing. The OOM killer selects a task in B as a victim, but someone asynchronously moves the task into C. mem_cgroup_get_oom_group() will iterate over all ancestors of C up to the root cgroup. In theory it had to stop at the oom_domain level - the memory cgroup which is OOMing. But because B is not an ancestor of C, it's not happening. Instead it chooses A (because it's oom.group is set), and kills all tasks in A. This behavior is wrong because the OOM happened in B, so there is no reason to kill anything outside. Fix this by checking it the memory cgroup to which the task belongs is a descendant of the oom_domain. If not, memory.oom.group should be ignored, and the OOM killer should kill only the victim task.

[PATCH 1/2] block: loop: set discard granularity and alignment for block device backed loop

From: Ming Lei <ming.lei(a)redhat.com> mainline inclusion from mainline-v5.9-rc3 commit bcb21c8cc9947286211327d663ace69f07d37a76 category: bugfix bugzilla: NA CVE: NA ------------------------------------------------- In case of block device backend, if the backend supports write zeros, the loop device will set queue flag of QUEUE_FLAG_DISCARD. However, limits.discard_granularity isn't setup, and this way is wrong, see the following description in Documentation/ABI/testing/sysfs-block: A discard_granularity of 0 means that the device does not support discard functionality. Especially 9b15d109a6b2 ("block: improve discard bio alignment in __blkdev_issue_discard()") starts to take q->limits.discard_granularity for computing max discard sectors. And zero discard granularity may cause kernel oops, or fail discard request even though the loop queue claims discard support via QUEUE_FLAG_DISCARD.

Block layer usually doesn't support or allow zero-length bvec. Since commit 1bdc76aea115 ("iov_iter: use bvec iterator to implement iterate_bvec()"), iterate_bvec() switches to bvec iterator. However, Al mentioned that 'Zero-length segments are not disallowed' in iov_iter. Fixes for_each_bvec() so that it can move on after seeing one zero length bvec.

[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.

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. 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

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

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,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

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 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

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. WARNING: Please note that about half of the TCP sockets are allocated from the IRQ context, so, memory used by such sockets will not be accouted by the memcg.

[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

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.

[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. Then, it also was attached as VND interface of rmnet1. This is unexpected behavior and there is no code for handling this case. So that below splat occurs when the rmnet0 interface is deleted. Splat looks like: [ 53.254112][ C1] WARNING: CPU: 1 PID: 1192 at net/core/dev.c:8992 rollback_registered_many+0x986/0xcf0 [ 53.254117][ C1] Modules linked in: rmnet dummy openvswitch nsh nf_conncount nf_nat nf_conntrack nf_defrag_ipv6 nfx [ 53.254182][ C1] CPU: 1 PID: 1192 Comm: ip Not tainted 5.8.0-rc1+ #620 [ 53.254188][ C1] Hardware name: innotek GmbH VirtualBox/VirtualBox, BIOS VirtualBox 12/01/2006 [ 53.254192][ C1] RIP: 0010:rollback_registered_many+0x986/0xcf0 [ 53.254200][ C1] Code: 41 8b 4e cc 45 31 c0 31 d2 4c 89 ee 48 89 df e8 e0 47 ff ff 85 c0 0f 84 cd fc ff ff 0f 0b e5 [ 53.254205][ C1] RSP: 0018:ffff888050a5f2e0 EFLAGS: 00010287 [ 53.254214][ C1] RAX: ffff88805756d658 RBX: ffff88804d99c000 RCX: ffffffff8329d323 [ 53.254219][ C1] RDX: 1ffffffff0be6410 RSI: 0000000000000008 RDI: ffffffff85f32080 [ 53.254223][ C1] RBP: dffffc0000000000 R08: fffffbfff0be6411 R09: fffffbfff0be6411 [ 53.254228][ C1] R10: ffffffff85f32087 R11: 0000000000000001 R12: ffff888050a5f480 [ 53.254233][ C1] R13: ffff88804d99c0b8 R14: ffff888050a5f400 R15: ffff8880548ebe40 [ 53.254238][ C1] FS: 00007f6b86b370c0(0000) GS:ffff88806c200000(0000) knlGS:0000000000000000 [ 53.254243][ C1] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 53.254248][ C1] CR2: 0000562c62438758 CR3: 000000003f600005 CR4: 00000000000606e0 [ 53.254253][ C1] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 53.254257][ C1] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 [ 53.254261][ C1] Call Trace: [ 53.254266][ C1] ? lockdep_hardirqs_on_prepare+0x379/0x540 [ 53.254270][ C1] ? netif_set_real_num_tx_queues+0x780/0x780 [ 53.254275][ C1] ? rmnet_unregister_real_device+0x56/0x90 [rmnet] [ 53.254279][ C1] ? __kasan_slab_free+0x126/0x150 [ 53.254283][ C1] ? kfree+0xdc/0x320 [ 53.254288][ C1] ? rmnet_unregister_real_device+0x56/0x90 [rmnet] [ 53.254293][ C1] unregister_netdevice_many.part.135+0x13/0x1b0 [ 53.254297][ C1] rtnl_delete_link+0xbc/0x100 [ 53.254301][ C1] ? rtnl_af_register+0xc0/0xc0 [ 53.254305][ C1] rtnl_dellink+0x2dc/0x840 [ 53.254309][ C1] ? find_held_lock+0x39/0x1d0 [ 53.254314][ C1] ? valid_fdb_dump_strict+0x620/0x620 [ 53.254318][ C1] ? rtnetlink_rcv_msg+0x457/0x890 [ 53.254322][ C1] ? lock_contended+0xd20/0xd20 [ 53.254326][ C1] rtnetlink_rcv_msg+0x4a8/0x890 [ ... ] [ 73.813696][ T1192] unregister_netdevice: waiting for rmnet0 to become free.

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

From: Marc Kleine-Budde <mkl(a)pengutronix.de> mainline inclusion from mainline-v5.4-rc1 commit ffd956eef69b212a724b1cc4cdc61828f3ad9104 category: feature bugzilla: 38684 CVE: NA --------------------------- This patch introduces the CAN midlayer private structure ("struct can_ml_priv") which should be used to hold protocol specific per device data structures. 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.

[PATCH 1/4] xfs: fix inode fork extent count overflow
by Yang Yingliang 16 Jun '20

16 Jun '20

From: Dave Chinner <dchinner(a)redhat.com> mainline inclusion from mainline-5.5-rc1 commit 3f8a4f1d876d3e3e49e50b0396eaffcc4ba71b08 category: bugfix bugzilla: 26723 CVE: NA --------------------------- [commit message is verbose for discussion purposes - will trim it down later. Some questions about implementation details at the end.] Zorro Lang recently ran a new test to stress single inode extent counts now that they are no longer limited by memory allocation. The test was simply: This test uncovered a problem where the hole punching operation appeared to finish with no error, but apparently only created 268M extents instead of the 10 billion it was supposed to. Further, trying to punch out extents that should have been present resulted in success, but no change in the extent count. It looked like a silent failure. While running the test and observing the behaviour in real time, I observed the extent coutn growing at ~2M extents/minute, and saw this after about an hour: > sleep 60 ; \ > xfs_io -f -c "stat" /mnt/scratch/big-file |grep next fsxattr.nextents = 127657993 fsxattr.nextents = 129683339 And a few minutes later this: fsxattr.nextents = 4177861124 Ah, what? Where did that 4 billion extra extents suddenly come from? Stop the workload, unmount, mount: fsxattr.nextents = 166044375 And it's back at the expected number. i.e. the extent count is correct on disk, but it's screwed up in memory. I loaded up the extent list, and immediately: fsxattr.nextents = 4192576215 It's bad again. So, where does that number come from? xfs_fill_fsxattr(): if (ip->i_df.if_flags & XFS_IFEXTENTS) fa->fsx_nextents = xfs_iext_count(&ip->i_df); else fa->fsx_nextents = ip->i_d.di_nextents; And that's the behaviour I just saw in a nutshell. The on disk count is correct, but once the tree is loaded into memory, it goes whacky. Clearly there's something wrong with xfs_iext_count(): inline xfs_extnum_t xfs_iext_count(struct xfs_ifork *ifp) { return ifp->if_bytes / sizeof(struct xfs_iext_rec); } Simple enough, but 134M extents is 2**27, and that's right about where things went wrong. A struct xfs_iext_rec is 16 bytes in size, which means 2**27 * 2**4 = 2**31 and we're right on target for an integer overflow. And, sure enough: struct xfs_ifork { int if_bytes; /* bytes in if_u1 */ .... Once we get 2**27 extents in a file, we overflow if_bytes and the in-core extent count goes wrong. And when we reach 2**28 extents, if_bytes wraps back to zero and things really start to go wrong there. This is where the silent failure comes from - only the first 2**28 extents can be looked up directly due to the overflow, all the extents above this index wrap back to somewhere in the first 2**28 extents. Hence with a regular pattern, trying to punch a hole in the range that didn't have holes mapped to a hole in the first 2**28 extents and so "succeeded" without changing anything. Hence "silent failure"... Fix this by converting if_bytes to a int64_t and converting all the index variables and size calculations to use int64_t types to avoid overflows in future. Signed integers are still used to enable easy detection of extent count underflows. This enables scalability of extent counts to the limits of the on-disk format - MAXEXTNUM (2**31) extents. Current testing is at over 500M extents and still going: fsxattr.nextents = 517310478 Reported-by: Zorro Lang <zlang(a)redhat.com> Signed-off-by: Dave Chinner <dchinner(a)redhat.com> Reviewed-by: Darrick J.

[PATCH 1/2] perf/x86: Make perf callchains work without CONFIG_FRAME_POINTER
by Yang Yingliang 15 Jun '20

15 Jun '20

From: Kairui Song <kasong(a)redhat.com> mainline inclusion from mainline-5.2-rc1 commit d15d356887e7 category: bugfix bugzilla: 35738 CVE: NA ------------------------------------------------- Currently perf callchain doesn't work well with ORC unwinder when sampling from trace point. We'll get useless in kernel callchain like this: perf 6429 [000] 22.498450: kmem:mm_page_alloc: page=0x176a17 pfn=1534487 order=0 migratetype=0 gfp_flags=GFP_KERNEL ffffffffbe23e32e __alloc_pages_nodemask+0x22e (/lib/modules/5.1.0-rc3+/build/vmlinux) 7efdf7f7d3e8 __poll+0x18 (/usr/lib64/libc-2.28.so) 5651468729c1 [unknown] (/usr/bin/perf) 5651467ee82a main+0x69a (/usr/bin/perf) 7efdf7eaf413 __libc_start_main+0xf3 (/usr/lib64/libc-2.28.so) 5541f689495641d7 [unknown] ([unknown]) The root cause is that, for trace point events, it doesn't provide a real snapshot of the hardware registers. Instead perf tries to get required caller's registers and compose a fake register snapshot which suppose to contain enough information for start a unwinding. However without CONFIG_FRAME_POINTER, if failed to get caller's BP as the frame pointer, so current frame pointer is returned instead. We get a invalid register combination which confuse the unwinder, and end the stacktrace early. So in such case just don't try dump BP, and let the unwinder start directly when the register is not a real snapshot. Use SP as the skip mark, unwinder will skip all the frames until it meet the frame of the trace point caller. Tested with frame pointer unwinder and ORC unwinder, this makes perf callchain get the full kernel space stacktrace again like this: perf 6503 [000] 1567.570191: kmem:mm_page_alloc: page=0x16c904 pfn=1493252 order=0 migratetype=0 gfp_flags=GFP_KERNEL ffffffffb523e2ae __alloc_pages_nodemask+0x22e (/lib/modules/5.1.0-rc3+/build/vmlinux) ffffffffb52383bd __get_free_pages+0xd (/lib/modules/5.1.0-rc3+/build/vmlinux) ffffffffb52fd28a __pollwait+0x8a (/lib/modules/5.1.0-rc3+/build/vmlinux) ffffffffb521426f perf_poll+0x2f (/lib/modules/5.1.0-rc3+/build/vmlinux) ffffffffb52fe3e2 do_sys_poll+0x252 (/lib/modules/5.1.0-rc3+/build/vmlinux) ffffffffb52ff027 __x64_sys_poll+0x37 (/lib/modules/5.1.0-rc3+/build/vmlinux) ffffffffb500418b do_syscall_64+0x5b (/lib/modules/5.1.0-rc3+/build/vmlinux) ffffffffb5a0008c entry_SYSCALL_64_after_hwframe+0x44 (/lib/modules/5.1.0-rc3+/build/vmlinux) 7f71e92d03e8 __poll+0x18 (/usr/lib64/libc-2.28.so) 55a22960d9c1 [unknown] (/usr/bin/perf) 55a22958982a main+0x69a (/usr/bin/perf) 7f71e9202413 __libc_start_main+0xf3 (/usr/lib64/libc-2.28.so) 5541f689495641d7 [unknown] ([unknown]) Co-developed-by: Josh Poimboeuf <jpoimboe(a)redhat.com> Signed-off-by: Kairui Song <kasong(a)redhat.com> Signed-off-by: Peter Zijlstra (Intel) <peterz(a)infradead.org> Cc: Alexander Shishkin <alexander.shishkin(a)linux.intel.com> Cc: Alexei Starovoitov <alexei.starovoitov(a)gmail.com> Cc: Arnaldo Carvalho de Melo <acme(a)kernel.org> Cc: Borislav Petkov <bp(a)alien8.de> Cc: Dave Young <dyoung(a)redhat.com> Cc: Jiri Olsa <jolsa(a)redhat.com> Cc: Linus Torvalds <torvalds(a)linux-foundation.org> Cc: Namhyung Kim <namhyung(a)kernel.org> Cc: Peter Zijlstra <peterz(a)infradead.org> Cc: Thomas Gleixner <tglx(a)linutronix.de> Link: https://lkml.kernel.org/r/20190422162652.15483-1-kasong@redhat.com Signed-off-by: Ingo Molnar <mingo(a)kernel.org> Signed-off-by: Wei Li <liwei391(a)huawei.com> Reviewed-by: Jian Cheng <cj.chengjian(a)huawei.com> Signed-off-by: Yang Yingliang <yangyingliang(a)huawei.com> --- arch/x86/events/core.c | 21 +++++++++++++++++---- arch/x86/include/asm/perf_event.h | 7 +------ arch/x86/include/asm/stacktrace.h | 13 ------------- include/linux/perf_event.h | 14 ++++++++++---- 4 files changed, 28 insertions(+), 27 deletions(-) diff --git a/arch/x86/events/core.c b/arch/x86/events/core.c index c89e6c6e26f6..0a6b48afeb05 100644 --- a/arch/x86/events/core.c +++ b/arch/x86/events/core.c @@ -2332,6 +2332,15 @@ void arch_perf_update_userpage(struct perf_event *event, cyc2ns_read_end();

[PATCH] panic/printk: fix zap_lock
by Yang Yingliang 15 Jun '20

15 Jun '20

From: Cheng Jian <cj.chengjian(a)huawei.com> hulk inclusion category: bugfix bugzilla: 34546 CVE: NA ---------------------------------------- There are two problems with the implementation and use of zap_lock(). Firstly, This console_sem does not require reinit in zap_lock(), this is because: 1). printk() itself does try_lock() and skips console handling when the semaphore is not available. 2). panic() tries to push the messages later in console_flush_on_panic(). It ignores the semaphore. Also most console drivers ignore their internal locks because oops_in_progress is set by bust_spinlocks(). Secondly, The situation is more complicated when NMI is not used. 1). Non-stopped CPUs are in unknown state, most likely in a busy loop. Nobody knows whether printk() is repeatedly called in the loop. When it was called, re-initializing any lock would cause double unlock and deadlock. 2). It would be possible to add some more hacks. One problem is that there are two groups of users. One prefer to risk a deadlock and have a chance to see the messages. Others prefer to always reach emergency_restart() and reboot the machine.

[PATCH] ALSA: proc: Avoid possible leaks of snd_info_entry objects
by Yang Yingliang 12 Jun '20

12 Jun '20

From: Takashi Iwai <tiwai(a)suse.de> mainline inclusion from mainline-v5.1-rc1 commit 3a55437141a1d287dead685b37fe240185144f15 category: bugfix bugzilla: 34614 CVE: NA ----------------------------------------------- This patch changes the parent pointer assignment of snd_info_entry object to be always non-NULL. More specifically,check the parent argument in snd_info_create_module_entry() & co, and assign snd_proc_root if NULL is passed there. This assures that the proc object is always freed when the root is freed, so avoid possible memory leaks. For example, some error paths (e.g. snd_info_register() error at snd_minor_info_init()) may leave snd_info_entry object although the proc file itself is freed.

[PATCH] irqchip/gic-v3-its: its supoport s3/s4
by Hongbo Yao 09 Jun '20

09 Jun '20

commit dba0bc7b76dcf(irqchip/gic-v3-its: add ability to save/restore ITS state) add support to save/restore its suspend state. However, it needs to set ITS_FLAGS_SAVE_SUSPEND_STATE to 1 when we want to resend MAPC. In GIC500, GITS_typer.HCC is not zero, and it can be used to judge if we can resend MAPC if the firmware restores the state, but when GITS_typer.HCC is zero, and it will never have chance to set the flag, which will lead to a failuer to power off GIC logic in suspend.

[PATCH v2] scsi: hisi_sas: directly trigger error handle of scsi instead of waiting for timeout
by Luo Jiaxing 05 Jun '20

05 Jun '20

We used timeout mechanism of scsi layer to trigger some IO's error handle, this type of abnormal IO require driver to enter error handle to clear the residue in the hardware. But timeout mechanism caught error handle time to be longer, some threads need to wait for tens of seconds when IO failed and enter error handle, so we try to trigger error handling directly.

[PATCH 01/76] net: dsa: Do not make user port errors fatal
by Yang Yingliang 01 Jun '20

From: Florian Fainelli <f.fainelli(a)gmail.com> commit 86f8b1c01a0a537a73d2996615133be63cdf75db upstream. Prior to 1d27732f411d ("net: dsa: setup and teardown ports"), we would not treat failures to set-up an user port as fatal, but after this commit we would, which is a regression for some systems where interfaces may be declared in the Device Tree, but the underlying hardware may not be present (pluggable daughter cards for instance).

[PATCH 1/9] net/hinic: Fix the firmware compatibility bug in the MAC reuse scenario
by Yang Yingliang 01 Jun '20

From: Chiqijun <chiqijun(a)huawei.com> driver inclusion category: bugfix bugzilla: 4472 ----------------------------------------------------------------------- 2.3.0.1 and later drivers and firmware add MAC reuse feature, when the driver is compatible with firmware version 2.3.0.0 and before, if the ip link command is used to configure the MAC and VLAN for the VF, it will cause the VF network anomaly. To solve this problem, the driver obtains the function capability from the firmware when loading, and determines whether to support MAC reuse for different processing.

[PATCH] irqchip/gic-v3-its: Probe ITS page size for all GITS_BASERn registers
by Yang Yingliang 01 Jun '20

01 Jun '20

From: Marc Zyngier <maz(a)kernel.org> mainline inclusion from mainline-v5.6-rc4 commit d5df9dc96eb7423d3f742b13d5e1e479ff795eaa category: bugfix bugzilla: NA CVE: NA --------------------------- The GICv3 ITS driver assumes that once it has latched on a page size for a given BASER register, it can use the same page size as the maximum page size for all subsequent BASER registers. Although it worked so far, nothing in the architecture guarantees this, and Nianyao Tang hit this problem on some undisclosed implementation. Let's bite the bullet and probe the the supported page size on all BASER registers before starting to populate the tables. This simplifies the setup a bit, at the expense of a few additional MMIO accesses.

[PATCH 1/4] vfio/mdev: Improve the create/remove sequence
by Yang Yingliang 01 Jun '20

01 Jun '20

From: Parav Pandit <parav(a)mellanox.com> mainline inclusion from mainline-5.2 commit 522ecce08ab20b57342d65b05601818e0f95fb2c category: bugfix bugzilla: NA CVE: NA ------------------------------------------------- This patch addresses below two issues and prepares the code to address 3rd issue listed below. 1. mdev device is placed on the mdev bus before it is created in the vendor driver. Once a device is placed on the mdev bus without creating its supporting underlying vendor device, mdev driver's probe() gets triggered. However there isn't a stable mdev available to work on. create_store() mdev_create_device() device_register() ... vfio_mdev_probe() [...] parent->ops->create() vfio_ap_mdev_create() mdev_set_drvdata(mdev, matrix_mdev); /* Valid pointer set above */ Due to this way of initialization, mdev driver who wants to use the mdev, doesn't have a valid mdev to work on. 2. Current creation sequence is, parent->ops_create() groups_register() Remove sequence is, parent->ops->remove() groups_unregister() However, remove sequence should be exact mirror of creation sequence. Once this is achieved, all users of the mdev will be terminated first before removing underlying vendor device. (Follow standard linux driver model). At that point vendor's remove() ops shouldn't fail because taking the device off the bus should terminate any usage. 3. When remove operation fails, mdev sysfs removal attempts to add the file back on already removed device. Following call trace [1] is observed. [1] call trace: kernel: WARNING: CPU: 2 PID: 9348 at fs/sysfs/file.c:327 sysfs_create_file_ns+0x7f/0x90 kernel: CPU: 2 PID: 9348 Comm: bash Kdump: loaded Not tainted 5.1.0-rc6-vdevbus+ #6 kernel: Hardware name: Supermicro SYS-6028U-TR4+/X10DRU-i+, BIOS 2.0b 08/09/2016 kernel: RIP: 0010:sysfs_create_file_ns+0x7f/0x90 kernel: Call Trace: kernel: remove_store+0xdc/0x100 [mdev] kernel: kernfs_fop_write+0x113/0x1a0 kernel: vfs_write+0xad/0x1b0 kernel: ksys_write+0x5a/0xe0 kernel: do_syscall_64+0x5a/0x210 kernel: entry_SYSCALL_64_after_hwframe+0x49/0xbe Therefore, mdev core is improved in following ways. 1. Split the device registration/deregistration sequence so that some things can be done between initialization of the device and hooking it up to the bus respectively after deregistering it from the bus but before giving up our final reference. In particular, this means invoking the ->create() and ->remove() callbacks in those new windows. This gives the vendor driver an initialized mdev device to work with during creation. At the same time, a bus driver who wish to bind to mdev driver also gets initialized mdev device. This follows standard Linux kernel bus and device model. 2. During remove flow, first remove the device from the bus. This ensures that any bus specific devices are removed. Once device is taken off the mdev bus, invoke remove() of mdev from the vendor driver. 3. The driver core device model provides way to register and auto unregister the device sysfs attribute groups at dev->groups. Make use of dev->groups to let core create the groups and eliminate code to avoid explicit groups creation and removal. To ensure, that new sequence is solid, a below stack dump of a process is taken who attempts to remove the device while device is in use by vfio driver and user application. This stack dump validates that vfio driver guards against such device removal when device is in use. cat /proc/21962/stack [<0>] vfio_del_group_dev+0x216/0x3c0 [vfio] [<0>] mdev_remove+0x21/0x40 [mdev] [<0>] device_release_driver_internal+0xe8/0x1b0 [<0>] bus_remove_device+0xf9/0x170 [<0>] device_del+0x168/0x350 [<0>] mdev_device_remove_common+0x1d/0x50 [mdev] [<0>] mdev_device_remove+0x8c/0xd0 [mdev] [<0>] remove_store+0x71/0x90 [mdev] [<0>] kernfs_fop_write+0x113/0x1a0 [<0>] vfs_write+0xad/0x1b0 [<0>] ksys_write+0x5a/0xe0 [<0>] do_syscall_64+0x5a/0x210 [<0>] entry_SYSCALL_64_after_hwframe+0x49/0xbe [<0>] 0xffffffffffffffff This prepares the code to eliminate calling device_create_file() in subsequent patch.

From: Wang ShaoBo <bobo.shaobowang(a)huawei.com> hulk inclusion category: bugfix bugzilla: 34588 CVE: NA ----------------------------------------------- There are two problems related to schemata: 1) When rmdir a group and then mkdir a new group under resctrl root directory, the new group still inherits the schemata configuration from old. e.g. > mount -t resctrl resctrl /sys/fs/resctrl > cd /sys/fs/resctrl > mkdir p1 && cd p1 > echo 'L3:0=7f' > schemata > cd .. && rmdir p1 && mkdir p1 && cd p1 > cat schemata L3:0=7f;1=7fff;2=7fff;3=7fff MB:0=100;1=100;2=100;3=100 2) It still exists when umount /sys/fs/resctrl and remount. e.g. > mount -t resctrl resctrl /sys/fs/resctrl > cd /sys/fs/resctrl > echo 'L3:0=7f' > schemata > umount /sys/fs/resctrl > mount -t resctrl resctrl /sys/fs/resctrl > cat schemata L3:0=7f;1=7fff;2=7fff;3=7fff MB:0=100;1=100;2=100;3=100 Firstly we make each resctrl resource obtains their corresponding default configuration. NOTE we use zero to initialize L3 default value instead of max cpbm bits, as zero configurarion equals to maximum configuration for L3 MSCs. And we use max-percentage masks of max bandwidth to generate maximum configuration for MB. Then we reset resources' configuration settings to default value and back MSCs to default state, when mkdir or umount happended.

From: Ben Hutchings <ben(a)decadent.org.uk> mainline inclusion from mainline-v5.3-rc1 commit 15b3cd8ef46ad1b100e0d3c7e38774f330726820 category: bugfix bugzilla: 34617 CVE: CVE-2019-12379 --------------------------- This reverts commit 84ecc2f6eb1cb12e6d44818f94fa49b50f06e6ac. con_insert_unipair() is working with a sparse 3-dimensional array: - p->uni_pgdir[] is the top layer - p1 points to a middle layer - p2 points to a bottom layer If it needs to allocate a new middle layer, and then fails to allocate a new bottom layer, it would previously free only p2, and now it frees both p1 and p2. But since the new middle layer was already registered in the top layer, it was not leaked. However, if it looks up an *existing* middle layer and then fails to allocate a bottom layer, it now frees both p1 and p2 but does *not* free any other bottom layers under p1. So it *introduces* a memory leak. The error path also cleared the wrong index in p->uni_pgdir[], introducing a use-after-free.

[PATCH 1/7] USB: gadget: fix illegal array access in binding with UDC
by Yang Yingliang 26 May '20

26 May '20

From: Kyungtae Kim <kt0755(a)gmail.com> mainline inclusion from mainline-v5.7-rc6 commit 15753588bcd4bbffae1cca33c8ced5722477fe1f category: bugfix bugzilla: 13690 CVE: CVE-2020-13143 ------------------------------------------------- FuzzUSB (a variant of syzkaller) found an illegal array access using an incorrect index while binding a gadget with UDC. Reference: https://www.spinics.net/lists/linux-usb/msg194331.html This bug occurs when a size variable used for a buffer is misused to access its strcpy-ed buffer. Given a buffer along with its size variable (taken from user input), from which, a new buffer is created using kstrdup(). Due to the original buffer containing 0 value in the middle, the size of the kstrdup-ed buffer becomes smaller than that of the original. So accessing the kstrdup-ed buffer with the same size variable triggers memory access violation. The fix makes sure no zero value in the buffer, by comparing the strlen() of the orignal buffer with the size variable, so that the access to the kstrdup-ed buffer is safe.

by Yang Yingliang 20 May '20

20 May '20

hulk inclusion category: kabi bugzilla: NA CVE: CVE-2020-10741, CVE-2020-12826 --------------------------- Commit d1e7fd6462ca ("signal: Extend exec_id to 64bits") can fixes CVE-2020-10741 and CVE-2020-12826, but it introduces a kabi change in struct task_strcut. Fix this kabi broken by using another new 64bits variables parent_exec_id_u64 and self_exec_id_u64.
