[PATCH OLK-5.10] coresight: Fix loss of connection info when a module is unloaded
by Junhao He 18 Oct '23

18 Oct '23

From: James Clark <james.clark(a)arm.com> mainline inclusion from mainline-v6.4-rc1 commit c45b2835e7b205783bdfe08cc98fa86a7c5eeb74 category: Bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I85PIL CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ---------------------------------------------------------------------- child_fwnode should be a read only property based on the DT or ACPI. If it's cleared on the parent device when a child is unloaded, then when the child is loaded again the connection won't be remade. child_dev should be cleared instead which signifies that the connection should be remade when the child_fwnode registers a new coresight_device. Similarly the reference count shouldn't be decremented as long as the parent device exists. The correct place to drop the reference is in coresight_release_platform_data() which is already done. Reproducible on Juno with the following steps: # load all coresight modules. $ cd /sys/bus/coresight/devices/ $ echo 1 > tmc_etr0/enable_sink $ echo 1 > etm0/enable_source # Works fine ^ $ echo 0 > etm0/enable_source $ rmmod coresight-funnel $ modprobe coresight-funnel $ echo 1 > etm0/enable_source -bash: echo: write error: Invalid argument Fixes: 37ea1ffddffa ("coresight: Use fwnode handle instead of device names") Fixes: 2af89ebacf29 ("coresight: Clear the connection field properly") Tested-by: Suzuki K Poulose <suzuki.poulose(a)arm.com> Reviewed-by: Mike Leach <mike.leach(a)linaro.org> Signed-off-by: James Clark <james.clark(a)arm.com> Signed-off-by: Suzuki K Poulose <suzuki.poulose(a)arm.com> Link: https://lore.kernel.org/r/20230425143542.2305069-2-james.clark@arm.com Signed-off-by: Junhao He <hejunhao3(a)huawei.com> --- drivers/hwtracing/coresight/coresight-core.c | 9 ++------- 1 file changed, 2 insertions(+), 7 deletions(-) diff --git a/drivers/hwtracing/coresight/coresight-core.c b/drivers/hwtracing/coresight/coresight-core.c index ee7b5cfcf786..9696f402a328 100644 --- a/drivers/hwtracing/coresight/coresight-core.c +++ b/drivers/hwtracing/coresight/coresight-core.c @@ -1443,13 +1443,8 @@ static int coresight_remove_match(struct device *dev, void *data) if (csdev->dev.fwnode == conn->child_fwnode) { iterator->orphan = true; coresight_remove_links(iterator, conn); - /* - * Drop the reference to the handle for the remote - * device acquired in parsing the connections from - * platform data. - */ - fwnode_handle_put(conn->child_fwnode); - conn->child_fwnode = NULL; + + conn->child_dev = NULL; /* No need to continue */ break; } -- 2.33.0

[PATCH OLK-5.10 00/24] coresight: Add new API to allocate trace source ID values
by Junhao He 17 Oct '23

17 Oct '23

From: xiabing <xiabing12(a)h-partners.com> The current method for allocating trace source ID values to sources is to use a fixed algorithm for CPU based sources of (cpu_num * 2 + 0x10). The STM is allocated ID 0x1. This fixed algorithm is used in both the CoreSight driver code, and by perf when writing the trace metadata in the AUXTRACE_INFO record. The method needs replacing as currently:- 1. It is inefficient in using available IDs. 2. Does not scale to larger systems with many cores and the algorithm has no limits so will generate invalid trace IDs for cpu number > 44. Additionally requirements to allocate additional system IDs on some systems have been seen. This patch set introduces an API that allows the allocation of trace IDs in a dynamic manner. Architecturally reserved IDs are never allocated, and the system is limited to allocating only valid IDs. Each of the current trace sources ETM3.x, ETM4.x and STM is updated to use the new API. For the ETMx.x devices IDs are allocated on certain events a) When using sysfs, an ID will be allocated on hardware enable, or a read of sysfs TRCTRACEID register and freed when the sysfs reset is written. b) When using perf, ID is allocated on during setup AUX event, and freed on event free. IDs are communicated using the AUX_OUTPUT_HW_ID packet. The ID allocator is notified when perf sessions start and stop so CPU based IDs are kept constant throughout any perf session.

[PATCH openEuler-1.0-LTS] ext4: fix rec_len verify error

16 Oct '23

From: Shida Zhang <zhangshida(a)kylinos.cn> stable inclusion from stable-v4.19.296 commit 996f30b44369fa2d1fe62d30a14ef27e05b30448 category: bugfix bugzilla: 189039, https://gitee.com/openeuler/kernel/issues/I7OXK8 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 7fda67e8c3ab6069f75888f67958a6d30454a9f6 upstream. With the configuration PAGE_SIZE 64k and filesystem blocksize 64k, a problem occurred when more than 13 million files were directly created under a directory: EXT4-fs error (device xx): ext4_dx_csum_set:492: inode #xxxx: comm xxxxx: dir seems corrupt? Run e2fsck -D. EXT4-fs error (device xx): ext4_dx_csum_verify:463: inode #xxxx: comm xxxxx: dir seems corrupt? Run e2fsck -D. EXT4-fs error (device xx): dx_probe:856: inode #xxxx: block 8188: comm xxxxx: Directory index failed checksum When enough files are created, the fake_dirent->reclen will be 0xffff. it doesn't equal to the blocksize 65536, i.e. 0x10000. But it is not the same condition when blocksize equals to 4k. when enough files are created, the fake_dirent->reclen will be 0x1000. it equals to the blocksize 4k, i.e. 0x1000. The problem seems to be related to the limitation of the 16-bit field when the blocksize is set to 64k. To address this, helpers like ext4_rec_len_{from,to}_disk has already been introduced to complete the conversion between the encoded and the plain form of rec_len. So fix this one by using the helper, and all the other in this file too.

[PATCH openEuler-1.0-LTS] efi: use 32-bit alignment for efi_guid_t literals
by Xia Fukun 11 Oct '23

11 Oct '23

From: Ard Biesheuvel <ardb(a)kernel.org> stable inclusion from stable-v5.10.198 commit 47ba0d4d2afb476e2a67f781166186e24b1e3bc1 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I878NW CVE: NA -------------------------------- commit fb98cc0b3af2ba4d87301dff2b381b12eee35d7d upstream. Commit 494c704f9af0 ("efi: Use 32-bit alignment for efi_guid_t") updated the type definition of efi_guid_t to ensure that it always appears sufficiently aligned (the UEFI spec is ambiguous about this, but given the fact that its EFI_GUID type is defined in terms of a struct carrying a uint32_t, the natural alignment is definitely >= 32 bits). However, we missed the EFI_GUID() macro which is used to instantiate efi_guid_t literals: that macro is still based on the guid_t type, which does not have a minimum alignment at all.

[PATCH openEuler-1.0-LTS] efi: use 32-bit alignment for efi_guid_t literals
by Xia Fukun 11 Oct '23

11 Oct '23

From: Ard Biesheuvel <ardb(a)kernel.org> stable inclusion from stable-5.10.198 commit 47ba0d4d2afb476e2a67f781166186e24b1e3bc1 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I878NW CVE: NA -------------------------------- commit fb98cc0b3af2ba4d87301dff2b381b12eee35d7d upstream. Commit 494c704f9af0 ("efi: Use 32-bit alignment for efi_guid_t") updated the type definition of efi_guid_t to ensure that it always appears sufficiently aligned (the UEFI spec is ambiguous about this, but given the fact that its EFI_GUID type is defined in terms of a struct carrying a uint32_t, the natural alignment is definitely >= 32 bits). However, we missed the EFI_GUID() macro which is used to instantiate efi_guid_t literals: that macro is still based on the guid_t type, which does not have a minimum alignment at all. This results in warnings such as In file included from drivers/firmware/efi/mokvar-table.c:35: include/linux/efi.h:1093:34: warning: passing 1-byte aligned argument to 4-byte aligned parameter 2 of 'get_var' may result in an unaligned pointer access [-Walign-mismatch] status = get_var(L"SecureBoot", &EFI_GLOBAL_VARIABLE_GUID, NULL, &size, ^ include/linux/efi.h:1101:24: warning: passing 1-byte aligned argument to 4-byte aligned parameter 2 of 'get_var' may result in an unaligned pointer access [-Walign-mismatch] get_var(L"SetupMode", &EFI_GLOBAL_VARIABLE_GUID, NULL, &size, &setupmode); The distinction only matters on CPUs that do not support misaligned loads fully, but 32-bit ARM's load-multiple instructions fall into that category, and these are likely to be emitted by the compiler that built the firmware for loading word-aligned 128-bit GUIDs from memory So re-implement the initializer in terms of our own efi_guid_t type, so that the alignment becomes a property of the literal's type.

[PATCH] RDMA/core: fix kabi compatibility for SRQ resource tracing
by Chengchang Tang 11 Oct '23

11 Oct '23

From: wenglianfa <wenglianfa(a)huawei.com> In the patch related to SRQ resource tracing, members are added to the structure, which causes Kapi incompatibility. To solve this problem, perform the following operations: First, make sure that the data structure of the new member has little impact and the risk is controllable, then Use the __GENKSYMS__ macro to shield the new structure members and place the new members at the end of the data structure. Fixes: d7b7ce53b3be ("RDMA/hns: Support SRQ restrack ops for hns driver") Fixes: 788310f83ffc ("RDMA/core: Add support to dump SRQ resource in RAW format") Fixes: 31cc28f1894f ("RDMA/core: Add dedicated SRQ resource tracker function") Fixes: f54d69b7874e ("RDMA/nldev: Add QP numbers to SRQ information") Fixes: 6102284160fd ("RDMA/nldev: Return SRQ information") Fixes: 4e38b5a1267f ("RDMA/restrack: Add support to get resource tracking for SRQ") Fixes: 0c32db26a6c4 ("RDMA/nldev: Return context information") Signed-off-by: wenglianfa <wenglianfa(a)huawei.com> --- include/rdma/ib_verbs.h | 9 +++++++-- include/rdma/restrack.h | 2 ++ include/uapi/rdma/rdma_netlink.h | 4 ++++ 3 files changed, 13 insertions(+), 2 deletions(-) diff --git a/include/rdma/ib_verbs.h b/include/rdma/ib_verbs.h index fc32b16d5bb3..db46f3150b99 100644 --- a/include/rdma/ib_verbs.h +++ b/include/rdma/ib_verbs.h @@ -1608,10 +1608,12 @@ struct ib_srq { }; } ext; +#ifndef __GENKSYMS__ /* * Implementation details of the RDMA core, don't use in drivers: */ struct rdma_restrack_entry res; +#endif }; enum ib_raw_packet_caps { @@ -2548,8 +2550,6 @@ struct ib_device_ops { int (*fill_res_qp_entry)(struct sk_buff *msg, struct ib_qp *ibqp); int (*fill_res_qp_entry_raw)(struct sk_buff *msg, struct ib_qp *ibqp); int (*fill_res_cm_id_entry)(struct sk_buff *msg, struct rdma_cm_id *id); - int (*fill_res_srq_entry)(struct sk_buff *msg, struct ib_srq *ib_srq); - int (*fill_res_srq_entry_raw)(struct sk_buff *msg, struct ib_srq *ib_srq); /* Device lifecycle callbacks */ /* @@ -2619,6 +2619,11 @@ struct ib_device_ops { DECLARE_RDMA_OBJ_SIZE(ib_srq); DECLARE_RDMA_OBJ_SIZE(ib_ucontext); DECLARE_RDMA_OBJ_SIZE(ib_xrcd); + +#ifndef __GENKSYMS__ + int (*fill_res_srq_entry)(struct sk_buff *msg, struct ib_srq *ib_srq); + int (*fill_res_srq_entry_raw)(struct sk_buff *msg, struct ib_srq *ib_srq); +#endif }; struct ib_core_device { diff --git a/include/rdma/restrack.h b/include/rdma/restrack.h index bdfb6fce0bed..57fca78afc47 100644 --- a/include/rdma/restrack.h +++ b/include/rdma/restrack.h @@ -49,10 +49,12 @@ enum rdma_restrack_type { * @RDMA_RESTRACK_COUNTER: Statistic Counter */ RDMA_RESTRACK_COUNTER, +#ifndef __GENKSYMS__ /** * @RDMA_RESTRACK_SRQ: Shared receive queue (SRQ) */ RDMA_RESTRACK_SRQ, +#endif /** * @RDMA_RESTRACK_MAX: Last entry, used for array dclarations */ diff --git a/include/uapi/rdma/rdma_netlink.h b/include/uapi/rdma/rdma_netlink.h index 05392cd8e627..5ab830103e32 100644 --- a/include/uapi/rdma/rdma_netlink.h +++ b/include/uapi/rdma/rdma_netlink.h @@ -293,11 +293,13 @@ enum rdma_nldev_command { RDMA_NLDEV_CMD_RES_MR_GET_RAW, +#ifndef __GENKSYMS__ RDMA_NLDEV_CMD_RES_CTX_GET, /* can dump */ RDMA_NLDEV_CMD_RES_SRQ_GET, /* can dump */ RDMA_NLDEV_CMD_RES_SRQ_GET_RAW, +#endif RDMA_NLDEV_NUM_OPS }; @@ -539,6 +541,7 @@ enum rdma_nldev_attr { RDMA_NLDEV_ATTR_RES_RAW, /* binary */ +#ifndef __GENKSYMS__ RDMA_NLDEV_ATTR_RES_CTX, /* nested table */ RDMA_NLDEV_ATTR_RES_CTX_ENTRY, /* nested table */ @@ -548,6 +551,7 @@ enum rdma_nldev_attr { RDMA_NLDEV_ATTR_MIN_RANGE, /* u32 */ RDMA_NLDEV_ATTR_MAX_RANGE, /* u32 */ +#endif /* * Always the end */ -- 2.33.0

[PATCH OLK-5.10] netfilter: nf_tables: disallow rule removal from chain binding
by Ziyang Xuan 10 Oct '23

10 Oct '23

From: Pablo Neira Ayuso <pablo(a)netfilter.org> mainline inclusion from mainline-v6.6-rc3 commit f15f29fd4779be8a418b66e9d52979bb6d6c2325 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I84NFY CVE: CVE-2023-5197 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… --------------------------- Chain binding only requires the rule addition/insertion command within the same transaction. Removal of rules from chain bindings within the same transaction makes no sense, userspace does not utilize this feature. Replace nft_chain_is_bound() check to nft_chain_binding() in rule deletion commands. Replace command implies a rule deletion, reject this command too. Rule flush command can also safely rely on this nft_chain_binding() check because unbound chains are not allowed since 62e1e94b246e ("netfilter: nf_tables: reject unbound chain set before commit phase").

[PATCH OLK-5.10 1/2] ring-buffer: Do not swap cpu_buffer during resize process
by Zheng Yejian 10 Oct '23

10 Oct '23

From: Chen Lin <chen.lin5(a)zte.com.cn> mainline inclusion from mainline-v6.5-rc3 commit 8a96c0288d0737ad77882024974c075345c72011 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I86Q1D Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ------------------------------------------------- When ring_buffer_swap_cpu was called during resize process, the cpu buffer was swapped in the middle, resulting in incorrect state. Continuing to run in the wrong state will result in oops. This issue can be easily reproduced using the following two scripts: /tmp # cat test1.sh //#! /bin/sh for i in `seq 0 100000` do echo 2000 > /sys/kernel/debug/tracing/buffer_size_kb sleep 0.5 echo 5000 > /sys/kernel/debug/tracing/buffer_size_kb sleep 0.5 done /tmp # cat test2.sh //#! /bin/sh for i in `seq 0 100000` do echo irqsoff > /sys/kernel/debug/tracing/current_tracer sleep 1 echo nop > /sys/kernel/debug/tracing/current_tracer sleep 1 done /tmp # ./test1.sh & /tmp # ./test2.sh & A typical oops log is as follows, sometimes with other different oops logs.

[PATCH OLK-5.10 01/24] vhost-vdpa: fix an iotlb memory leak
by Jiang Dongxu 09 Oct '23

09 Oct '23

From: jiangdongxu1 <jiangdongxu1(a)huawei.com> mainline inclusion from v6.2-rc3 commit c070c1912a83432530cbb4271d5b9b11fa36b67a category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I86ITO Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Before commit 3d5698793897 ("vhost-vdpa: introduce asid based IOTLB") we called vhost_vdpa_iotlb_unmap(v, iotlb, 0ULL, 0ULL - 1) during release to free all the resources allocated when processing user IOTLB messages through vhost_vdpa_process_iotlb_update(). That commit changed the handling of IOTLB a bit, and we accidentally removed some code called during the release. We partially fixed this with commit 037d4305569a ("vhost-vdpa: call vhost_vdpa_cleanup during the release") but a potential memory leak is still there as showed by kmemleak if the application does not send VHOST_IOTLB_INVALIDATE or crashes: unreferenced object 0xffff888007fbaa30 (size 16): comm "blkio-bench", pid 914, jiffies 4294993521 (age 885.500s) hex dump (first 16 bytes): 40 73 41 07 80 88 ff ff 00 00 00 00 00 00 00 00 @sA............. backtrace: [<0000000087736d2a>] kmem_cache_alloc_trace+0x142/0x1c0 [<0000000060740f50>] vhost_vdpa_process_iotlb_msg+0x68c/0x901 [vhost_vdpa] [<0000000083e8e205>] vhost_chr_write_iter+0xc0/0x4a0 [vhost] [<000000008f2f414a>] vhost_vdpa_chr_write_iter+0x18/0x20 [vhost_vdpa] [<00000000de1cd4a0>] vfs_write+0x216/0x4b0 [<00000000a2850200>] ksys_write+0x71/0xf0 [<00000000de8e720b>] __x64_sys_write+0x19/0x20 [<0000000018b12cbb>] do_syscall_64+0x3f/0x90 [<00000000986ec465>] entry_SYSCALL_64_after_hwframe+0x63/0xcd Let's fix this calling vhost_vdpa_iotlb_unmap() on the whole range in vhost_vdpa_remove_as(). We move that call before vhost_dev_cleanup() since we need a valid v->vdev.mm in vhost_vdpa_pa_unmap(). vhost_iotlb_reset() call can be removed, since vhost_vdpa_iotlb_unmap() on the whole range removes all the entries. The kmemleak log reported was observed with a vDPA device that has `use_va` set to true (e.g. VDUSE). This patch has been tested with both types of devices.

driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I86GWG CVE: NA ----------------------------------------------------------------------- We find that some disks use D2H frame instead of SDB frame to return NCQ error. Currently, only the I/O corresponding to the D2H frame is processed in this scenario, which does not meet the processing requirements of the NCQ error scenario. So we set dev_status to HISI_SAS_DEV_NCQ_ERR and abort all I/Os of the disk in this scenario.

[PATCH OLK-5.10 v2] RDMA/irdma: Prevent zero-length STAG registration
by Liu Jian 08 Oct '23

08 Oct '23

From: Christopher Bednarz <christopher.n.bednarz(a)intel.com> mainline inclusion from mainline-v6.6-rc1 commit bb6d73d9add68ad270888db327514384dfa44958 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I7YFVN CVE: CVE-2023-25775 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… --------------------------- Currently irdma allows zero-length STAGs to be programmed in HW during the kernel mode fast register flow. Zero-length MR or STAG registration disable HW memory length checks. Improve gaps in bounds checking in irdma by preventing zero-length STAG or MR registrations except if the IB_PD_UNSAFE_GLOBAL_RKEY is set. This addresses the disclosure CVE-2023-25775.
