[PATCH OLK-5.10 1/3] iommu/arm-smmu-v3: Fix ECMDQs is not initialized correctly
From: Zhen Lei <thunder.leizhen@huawei.com> hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6WAZX -------------------------------- When the number of cores is greater than the number of ECMDQs, the number of ECMDQs occupied by each NUMA node is less than the number of cores of the node. Therefore, the first smmu->nr_ecmdq cores do not cover all ECMDQs. For example: --------------------------------------- | Node0 | Node1 | |---------------------------------------| | 0 1 2 3 | 4 5 6 7 | CPU ID |---------------------------------------| | 0 1 | 2 3 | ECMDQ ID --------------------------------------- Fixes: 3965519baff5 ("iommu/arm-smmu-v3: Add support for less than one ECMDQ per core") Signed-off-by: Zhen Lei <thunder.leizhen@huawei.com> Reviewed-by: Xie XiuQi <xiexiuqi@huawei.com> Signed-off-by: Jialin Zhang <zhangjialin11@huawei.com> --- drivers/iommu/arm/arm-smmu-v3/arm-smmu-v3.c | 114 ++++++++++++-------- drivers/iommu/arm/arm-smmu-v3/arm-smmu-v3.h | 3 +- 2 files changed, 73 insertions(+), 44 deletions(-) diff --git a/drivers/iommu/arm/arm-smmu-v3/arm-smmu-v3.c b/drivers/iommu/arm/arm-smmu-v3/arm-smmu-v3.c index be8cc53659f8..1ee14a59a3d6 100644 --- a/drivers/iommu/arm/arm-smmu-v3/arm-smmu-v3.c +++ b/drivers/iommu/arm/arm-smmu-v3/arm-smmu-v3.c @@ -386,7 +386,7 @@ static struct arm_smmu_cmdq *arm_smmu_get_cmdq(struct arm_smmu_device *smmu) if (smmu->ecmdq_enabled) { struct arm_smmu_ecmdq *ecmdq;

The ondisk AGF has a higher LSN than the recovered log item. xlog_recover_buf_commit_pass2 reads the buffer, compares the LSNs, and decides to skip replay because the ondisk buffer appears to be newer. Unfortunately, the ondisk buffer is corrupt, but recovery just read the buffer with no buffer ops specified: error = xfs_buf_read(mp->m_ddev_targp, buf_f->blf_blkno, buf_f->blf_len, buf_flags, &bp, NULL); Skipping the buffer leaves its contents in memory unverified. This sets us up for a kernel crash because xfs_refcount_recover_cow_leftovers reads the buffer (which is still around in XBF_DONE state, so no read verification) and creates a refcountbt cursor of height 32. This is impossible so we run off the end of the cursor object and crash. Fix this by invoking the verifier on all skipped buffers and aborting log recovery if the ondisk buffer is corrupt. It might be smarter to force replay the log item atop the buffer and then see if it'll pass the write verifier (like ext4 does) but for now let's go with the conservative option where we stop immediately.
