概要
Linux/Unix 主機上安裝的一個或多個套件存有弱點，供應商表示將不會修補。說明
Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且廠商未提供可用的修補程式。- riscvcpu_ops_sbi使用 boot_data 的靜態陣列自從提交 6b9f29b81b15 (riscv啟用 pcpu 頁面第一個區塊配置器)如果已啟用 NUMA則頁面 percpu 配置器可能用於非常疏鬆的組態或在以 percpu_alloc=page 開機時提出要求時。在這種情況下percpu 資料會放置在 vmalloc 區域中。不過sbi_hsm_hart_start() 需要 sbi_hart_boot_data 的實體位址且只會假設 __pa() 會運作。這會造成剛啟動的 hart 立即存取無效位址並造成懸置。幸好 sbi_hart_boot_data 結構並不算大所以我們可以簡單地以靜態方式為 boot_data 配置陣列將其放置在核心影像中。這可修正 Sophgo 上的 NUMA=y SMP 開機 SG2042。若要在 QEMU 上重現設定 CONFIG_NUMA=y 和 CONFIG_DEBUG_VIRTUA=y然後透過以下項目執行 qemu-system-riscv64 -M virt -smp 2 -nographic\ -kernel arch/riscv/boot/Image \ -append percpu_alloc=page 核心輸出[ 0.000000] hartid 0 上的 Linux 開機 [ 0.000000] Linux 6.16.0-rc1 版 (dram@sakuya) (riscv64-unknown-linux-gnu-gcc (GCC) 14.2.1 20250322、GNU ld (GNU Binutils) 2.44) #11 SMP 6 月 24 日星期二14:56:22 CST 2025 ...
