Itamar	50fd2cabff	ptrace: Report error in PT_PEEK via errno ... The syscall wrapper for ptrace needs to return the peeked value when using PT_PEEK. Because of this, the user has to check errno to detect an error in PT_PEEK. This commit changes the actual syscall's interface (only for PT_PEEK) to allow the syscall wrapper to detect an error and change errno.	2020-04-13 00:53:22 +02:00
Itamar	9e51e295cf	ptrace: Add PT_SETREGS ... PT_SETTREGS sets the regsiters of the traced thread. It can only be used when the tracee is stopped. Also, refactor ptrace. The implementation was getting long and cluttered the alraedy large Process.cpp file. This commit moves the bulk of the implementation to Kernel/Ptrace.cpp, and factors out peek & poke to separate methods of the Process class.	2020-04-13 00:53:22 +02:00
