1. **修复:** 进程 CPU 时间统UserUContext 计精度，将统计基准调整为扣除 IRQ 和 Steal 时间后的净时间（accounted_cputime），避免将硬件中断处理时间错误计入进程的 utime/stime 2. **修复:** `sys_rt_sigtimedwait`: - 修复了信号等待逻辑，确保即使 等待信号集 为空也能正确进入 do_kernel_rt_sigtimedwait，符合 Linux 行为。 - 修复潜在的无限睡眠问题：当线程被非目标信号或非超时事件唤醒时，将正确返回 EINTR，避免进程一直挂起。 - 修复了bitflags错误移除的bug，应该使用remove()。 3. **修复:** `sys_rt_sigreturn:`: - 当从信号处理函数返回用户态时，内核错误地使用 sysretq 来处理 sys_rt_sigreturn 的返回，%rcx 和 %r11 这两个寄存器被意外破坏。 - 修复：如果待恢复的 %rcx / %r11 与 sysretq 的行为冲突，则强制跳转到 .L_syscall_must_use_iret 分支，使用 iretq 指令精确恢复完整的上下文。 TODO: 目标线程的 TGID 没有正确设置为 leader 的 PID，导致还有两个sys_rt_sigtimedwait的测例无法通过。 ```sh Value of: tgkill(getpid(), tid, kSigno) Expected: not -1 (success) Actual: -1 (of type int), with errno PosixError(errno=3 No such process) ``` --------- Signed-off-by: aLinChe <1129332011@qq.com> |

Lightweight Cloud-Native Kernel
DragonOS
Languages 中文|English
DragonOS is a 64-bit operating system with a completely independent kernel, designed for lightweight cloud computing scenarios, offering Linux binary compatibility. It aims to provide lightweight, high-performance solutions for containerized workloads. Developed using Rust for enhanced reliability.
The DragonOS open-source community was established in July 2022 and is entirely commercially neutral. We warmly welcome interested developers and enthusiasts to join us!
DragonOS features excellent and comprehensive architectural design. Compared to other systems of similar scale, DragonOS supports eBPF and virtualization. Currently, we are actively advancing container support, cloud platform compatibility, RISC-V support, as well as porting compilers and application software. Our goal is to achieve large-scale production environment deployment within five years.
DragonOS is rapidly evolving under community-driven development. Currently, DragonOS has implemented approximately 1/4 of Linux interfaces. In the future, we will provide 100% Linux compatibility along with new features.
