PMD - ソースコードアナライザ PMD は拡張可能な多言語対応静的コード解析ツールです。未使用変数、空の catch ブロック、不要なオブジェクト生成といった一般的なプログラミングの欠陥を検出します。主に Java と Apex を対象としていますが、他の16言語もサポート しています。400以上の組み込みルール が付属しており、カスタムルールで拡張することもできます。JavaCC と Antlr を使用してソースファイルを抽象構文木 AST に解析し、ルールを適用して違反を見つけます。ルールは Java または XPath クエリで記述できます。 現在、PMD は...

kernel: arm64: tlb: Flush walk cache when unsharing PMD tables

A flaw was found in the Linux kernel, specifically within the arm64 architecture's Translation Lookaside Buffer TLB management. When a Page Middle Directory PMD table was unshared, the TLB flush operation did not correctly invalidate entries in the walk cache. This oversight could leave stale PMD...
