Previously, __export_parasite_cmd was located in parasite-head.S, and __export_parasite_args located exactly at the end of the parasite blob. This is not ideal for various reasons: 1) These two variables work together. It would be preferrable to have them in the same location 2) This prevent us from allocating another section betweeen the parasite blob and the args area. We'll need this to allocate a GOT table This commit changes the allocation of these symbols from assembly/linker script to a C file. Moreover, the assembly entry points that invoke parasite_service() prepares arguments with hand crafted assembly. This is unecessary. This commit rewrite this logic with regular C code. Note: if it wasn't for the x86 compat mode, we could remove all parasite-head.S files and directly jump to parasite_service() via ptrace. An int3 architecture specific equivalent could be called at the end of parasite_service() with an inline asm statement. Signed-off-by: Nicolas Viennot <Nicolas.Viennot@twosigma.com>
