Antes do lançamento do Kernel Linux 6.5-rc2, foi mesclado um conjunto de alterações no código do kernel x86/x86_64 durante a noite para lidar com algumas vulnerabilidades no código de Integridade do Fluxo de Controle (kCFI) / FineIBT (Indirect Branch Tracking) do kernel.
Embora haja muito o que amar no RISC-V, com a infinidade de extensões do RISC-V, alguns dos acrônimos são difíceis de digerir. O exemplo mais recente são os patches do kernel do Linux para "zisslpcfi", que é a extensão RISC-V em torno do suporte de integridade de fluxo de controle (CFI) para processadores RISC-V.
O Fwupd 1.8.10 foi lançado ontem de manhã para iniciar uma nova semana e continuar a aprimorar o suporte de atualização de firmware de código aberto em sistemas Linux.
Nos últimos anos, tornou-se possível compilar o kernel Linux principal com LLVM/Clang em comparação com a dependência de longa data do uso do compilador GCC. Embora tenha sido possível por mais de 3 anos usar o kernel Linux principal e o Clang principal para criar um kernel x86_64 e AArch64 funcional, o processo e o suporte continuam a amadurecer.
Na véspera de Ano Novo, Greg Kroah-Hartman lançou um novo conjunto de kernels estáveis com o Kernel Linux 6.1.2, 6.0.16 e 5.15.86 LTS sendo o novo conjunto.
