fix: solve SIGCHLD ignored in sigsuspend()
...
在如下场景signal可能得不到及时处理:
1、进程A设置信号a阻塞
2、进程A收到信号a
3、进程A调用sigsuspend结束阻塞
原则上,步骤三应该立刻处理之前被阻塞的信号a,调用信号处理函数,并且sigsuspend
返回。现在的问题是,信号a没有得到及时处理,并且进程A阻塞在sigsuspend()调用流程
。
本次修改,在1、2、3场景下,sigsuspend()处理过程中,如果发现已经收到信号,待处理
时,会立刻进行调度切换,再次调度回来时,在调度模块中,会先主动处理已经收到的信
号,最后sigsuspend返回用户态。

fix: 3518平台, 异常测试进程无法正常退出
...
用户态线程在用户态处于while(1), 在中断处理时使该线程处于READY状态,
此时进程退出时该线程无法被正常回收,导致进程无法合理退出。

feat: timer_create支持以SIGEV_THREAD方式创建定时器
...
【背景】当前timer_create接口不支持以SIGEV_THREAD的方式创建多个定时器
【修改方案】
1、内核timer_create接口在创建software timers相应的线程时,使用线程
taskCB所携带的信息识别各个线程的信号并依据该信息分别派发出信号。
2、关于用户任务操作许可验证的修改,现在允许同一用户线程向其自身派发信
号,软件定时器计时结束,向用户态发送相应的信号,完成用户态线程的回调。
【影响】
对现有的产品暂无影响。

fix: 解决kill进程时无法保证进程的已持有的内核资源合理释放.
...
背景: 当前信号实现原理是在系统调用结束和中断结束时检查是否有信号处理,
如果有信号处理就切去处理信号,信号处理结束后回来继续按原来流程执行。
问题:当用户态线程在执行系统调用或缺页异常时,运行在内核态,如果此时有信
号需要处理,且该线程已经持有了部分内核资源(如:锁,内存等), 此时如
果有中断发生,则在中断结束时,就会去处理该信号,此时用户态线程持有
了内核未释放的资源跑到了用户态去运行,如果该线程在用户态出现问题,
那么它持有的内核资源就无法被释放了。
方案:用户态线程在执行系统调用和缺页异常时暂时屏蔽信号,防止此时有中断去
处理信号,等系统调用结束或缺页异常结束时再去处理信号。
解决的问题:
1. 执行系统调用或缺页异常时屏蔽信号,防止中断去处理信号
2.解决无法kill 因为用户态的锁、ipc等阻塞的用户态线程
3.进程退出方式转变为: 依次通过kill去杀死该进程的所有线程
