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，且供應商未提供可用的修補程式。- btrfs略過在記錄清理失敗後對卸載提出的保留位元組警告在認可 c2e39305299f01 進行的最近變更之後 (btrfs 當我們無法寫入時清除範圍緩衝區 uptodate) 及其後續修正認可後 651740a5024117 (btrfs嘗試在讀取範圍緩衝區)時，我們現在可以在交易中止發生後，最終不清理記錄樹狀結構範圍緩衝區的空間保留，以及不清理靜止的已變更範圍緩衝區。會發生這種情況是因為如果記錄樹狀結構範圍緩衝區回寫失敗是因為我們已清除範圍緩衝區中的 EXTENT_BUFFER_UPTODATE 位元而且我們也已在其上設定 EXTENT_BUFFER_WRITE_ERR 位元。之後當嘗試使用 free_log_tree() 反覆使用樹狀結構來釋放記錄樹狀結構時我們最終可能會在嘗試讀取節點或分葉時遇到 -EIO 錯誤因為 read_extent_buffer_pages() 會在範圍緩衝區未設定 EXTENT_BUFFER_UPTODATE但已設定 EXTENT_BUFFER_WRITE_ERR 位元。取得 -EIO 表示我們會立即傳回因為我們無法逐一查看整個樹狀結構。在此情況下我們絕不會更新個別區塊群組與 space_info 物件中範圍緩衝區的保留空間。若發生此情況我們在卸載 fs 時會收到下列追踪[174957.284509] BTRFScleanup_transaction:1913 中的錯誤 (dm-0)errno=-5 IO 失敗 [174957.286497] ] BTRFS錯誤 (裝置 dm-0)在 free_log_tree:3420 中errno=-5 IO 失敗 [174957.399379] ------------[cut here ]------------ [174957.402497] 警告CPU 2 PID: 3206883@fs/btrfs/block-group.c:127 btrfs_put_block_group+0x77/0xb0 [btrfs] [174957.407523] 連結的模組btrfs overlay dm_zero (...)
