However, if that has been installed relocatable, the above command fails.
It requires the relocatable path as the parameter
installp -R <relocation_path> -u <package_name>

Hi All,
Is there a max number of slabs that can be used per kernel module? I'm having a tough time finding out that kind of information, but the array 'node_zonelists' (mmzone.h) has a size of 5. I just want to avoid buffer overruns and other bad stuff.
Cheers,

RAGG2(1) BSD General Commands Manual RAGG2(1)
NAME
ragg2 -- radare2 utility to run programs in exotic environments
SYNOPSIS
ragg2 [-a arch] [-b bits] [-k kernel] [-f format] [-o file] [-i shellcode] [-I path] [-e encoder] [-B hexpairs] [-c k=v] [-C file]
[-d off:dword] [-D off:qword] [-w off:hexpair] [-p padding] [-FOLsrxvh]
DESCRIPTION
ragg2 is a frontend for r_egg, compile programs into tiny binaries for x86-32/64 and arm.
This tool is experimental and it is a rewrite of the old rarc2 and rarc2-tool programs as a library and integrated with r_asm and r_bin.
Programs generated by r_egg are relocatable and can be injected in a running process or on-disk binary file.
ragg2-cc is another tool that comes with r2 and it is used to generate shellcodes from C code. The final code can be linked with rabin2 and
it is relocatable, so it can be used to inject it on any remote process.
ragg2-cc is conceptually based on shellforge4, but only linux/osx x86-32/64 platforms are supported.
DIRECTIVES
The rr2 (ragg2) configuration file accepts the following directives, described as key=value entries and comments defined as lines starting
with '#'.
-a arch set architecture x86, arm
-b bits 32 or 64
-k kernel windows, linux or osx
-f format select binary format (pe, elf, mach0)
-o file output file to write result of compilation
-i shellcode
specify shellcode name to be used (see -L)
-e encoder specify encoder name to be used (see -L)
-B hexpair specify shellcode as hexpairs
-c k=v set configure option for the shellcode encoder. The argument must be key=value.
-C file include contents of file
-d off:dword
Patch final buffer with given dword at specified offset
-D off:qword
Patch final buffer with given qword at specified offset
-w off:hexpairs
Patch final buffer with given hexpairs at specified offset
-p padding Specify generic paddings with a format string.
-F autodetect native file format (osx=mach0, linux=elf, ..)
-O use default output file (filename without extension or a.out)
-I path add include path
-s show assembler code
-x execute (just-in-time)
EXAMPLE
$ cat hi.r
/* hello world in r_egg */
write@syscall(4);
exit@syscall(1);
main@global(128) {
.var0 = "hi!0;
write(1,.var0, 4);
exit(0);
}
$ ragg2 -O -F hi.r
$ ./hi
hi!
$ cat hi.c
main() {
write(1, "Hello0, 6);
exit(0);
}
$ ragg2 hi.c
$ ./hi.c.bin
Hello
