6cfe56202d Backout 3f731241cb. It is a good idea, but has some unpleasant side effect... like SYSLOG and dbg() no longer work 2016-04-18 18:55:36 -06:00
Gregory Nutt
3f731241cb fs/inode/, fs/vfs/, and sched/task/: File and socket descriptors are no longer allocated for kernel threads. They must use SYSLOG for output and the low-level psock interfaces for network I/O. This saves a little memory which might be important for small footprint configurations. 2016-04-14 10:14:38 -06:00

a633353ec3 Add a CPU affinity set to the TCB if SMP is enable and use this CPU set as a mask for determining which CPUs the thread may run on. Add an affinity field to the attrributes to permit controlling which CPUs a pthread may run on. Implements pthread_att_setaffinity_np() and pthread_attr_getaffinity_np(). 2016-02-19 17:33:35 -06:00

937f9f23f1 strncpy will not copy the terminating \0 into the destination if the source is larger than the size of the destination. Ensure that the last byte is always zero and let strncpy only copy CONFIG_TASK_NAME_SIZE bytes. The issue of unterminated names can be observed in ps when creating a pthread while CONFIG_TASK_NAME_SIZE is set to 8. 2014-12-17 12:24:02 -06:00

1dc9768c1a Fix vfork(). Now that arguments are kept on the stack, the way that arguments are passed from parent to child in vfork() must change. This bug has always been present, but was not visible with the old strdup() way of passing arguments 2014-09-29 10:45:44 -06:00
