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

f8170550e1 ARMv7-A: Modify up_fullcontextrestore() for CONFIG_BUILD_KERNEL. It changed CPSR while in kernel. That will crash is the new CPSR is user mode while executing in kernel space. Fixed by adding a SYS_context_restore system call. There is an alternative, simpler modification to up_fullcontextrestore() that could have been done: It might have been possible to use the SPSR instead of the CPRSR and then do an exception return from up_fullcontextrestore(). That would be more efficient, but I never tried it. 2014-09-12 08:04:27 -06:00

Gregory Nutt
64ab35b399 There used to be two ways to pass parameters to new tasks, depending upon the configuration: Either (1) argv[] as created as an array with each string strdup'ed. Or (1) argv[] array and strings were created on the stack before the new task was started. Now, there is only one way, way (1). Way (2) might be slightly more compact, but this is not worth carry the complexity of two different ways of doing the same thing. 2014-09-01 15:39:34 -06:00

c9661ad5a7 Change all time conversions. Yech. New timer units in microseconds breaks all existing logic that used milliseconds in the conversions.
