BUGS
|
|
----
|
|
* RBinCreate:
|
|
- mach0 create for darwin-ppc
|
|
- mz
|
|
- pe64
|
|
- plan9 bins
|
|
* Implement support for args in 'oo' (like in r1s !load debugger..)
|
|
* opening a file from inside r2 doesnt clears internal data (strings..)
|
|
* backtrace for linux or osx at least
|
|
* implement 'ax' to get/set xrefs (better than afl <addr>) .. or afx?
|
|
* shell encoder - get x86-64 one from twitter
|
|
- http://funoverip.net/2011/09/simple-shellcode-obfuscation/
|
|
- shellforge.. and review current shellcodes :?
|
|
* rasm2 must support binary creation help message or so..
|
|
- rabin2 integration must be easier
|
|
* rabin2 -z /dev/sda1 TAKES TOO LONG. opening r2 /tmp/fs is SLOW as shit.
|
|
|
|
* Add support for classes in c++, objc binaries
|
|
- command to add new classes
|
|
* Tracing support for the debugger
|
|
- "e cmd.trace=dr=;.dr*;pd 2@eip"
|
|
- dca sym.main imp.printf
|
|
- dbc
|
|
|
|
** BUG **
|
|
* fix for indirect list manipulations -- looks like a similar problem with r_cons recusivity
|
|
- when you are iterating a list you CANT remove items from it
|
|
- this is..you CANT call r_core_cmd() while iterating flags unless you want to crash
|
|
- we probably need to queue the deletions and use a commit-like methodology
|
|
- this way we avoid duplications
|
|
RListBox *b = r_flag_get_list ();
|
|
r_list_foreach (b, iter, item) {
|
|
r_list_delete_iter_later (b, iter);
|
|
}
|
|
r_list_commit (b);
|
|
|
|
* Add r_cons_prompt () ... calling set_prompt + fgets -- this api needs cleanup
|
|
- set prompt, set line, fgets
|
|
- strict width in visual
|
|
* REFACTOR of disasm loop XDDDDD -1 (r2<1.0 plzz)
|
|
- arch dependent anal code must be removed from disasm loop +1
|
|
|
|
nibble
|
|
------
|
|
* Analyze this opcode: ff2518130000 jmp qword [rip+0x1318]
|
|
* Support for proper analyze of TinyPE binaries
|
|
* Do not show XREF info if in the same function?
|
|
* r_anal
|
|
- Code analysis (detect when an argument is a flagmask or
|
|
enum and display text format) (ollydbg)
|
|
* r_bin
|
|
- PE: native subsystem? http://radare.org/get/w32/mrxnet.tgz
|
|
* Fix RAnalCond
|
|
* code analysis must resolve jump tables
|
|
* allow to hook r_asm_disassemble and assemble with custom callbacks
|
|
- extend a disassembler with own instructions.
|
|
* For each "call" or "push offset"+"ret" create a function.
|
|
- And, if deep code analysis is enabled:
|
|
- Search every possible function by searching typical prologs and put them in a queue.
|
|
- Perform the same actions as in the previous steps with the entry points.
|
|
* detect strings in code analysis
|
|
* register renaming (per-instruction or ranges)
|
|
- r_parser fun? a specific asm.parser plugin that does all this tricks?
|
|
* Display getsym() stuff in rabin2, not only legit syms
|
|
* dmi command must read from memory if no file path provided
|
|
- rabin from memory ftw, to get libnames of dll, so..
|
|
* add support for sign/unsigned registers..or at least a way to cast them
|
|
* use r_anal_value everywhere
|
|
* diff code analysis
|
|
- diff two programs
|
|
1st level:
|
|
- check all functions EQUAL, DIFFERENT, REMOVED, ADDED
|
|
- check all symbols
|
|
- check all imports
|
|
- check all strings
|
|
2nd level:
|
|
- basic block level diffing (output in graph mode)
|
|
|
|
earada
|
|
------
|
|
* Add print support for bitfields (pm b...)
|
|
* Fix io_haret memory dump
|
|
* refactor rap and raps
|
|
* remove all uses of alloca() // mingw and grep reports them all :)
|
|
* typedef all function pointers, like in r_bp
|
|
* Implement /. to search using a file .. isnt zignatures about this?
|
|
* Implement search and replace /s
|
|
- insert or append? (see r1 cfg vars)
|
|
|
|
Assembler
|
|
---------
|
|
* Embed bits/arch/endian in a separated structure
|
|
- So one can change from one arch to another with a pointer
|
|
- Cool for defining ranges of memory
|
|
|
|
* r_io
|
|
- We need a way to get the underlying file which responds
|
|
to the read call (this way we can know which library
|
|
lives at a specified offset. (is this already done?)
|
|
|
|
* radare2
|
|
- Use r_bin with r_io to get symbols
|
|
- The offset to read will define the module to analyze and retrieve syms
|
|
- Import msdn doc as comments
|
|
|
|
RDB
|
|
---
|
|
- Implement iterators r_db_next() and r_db_prev() (HIGH PRIO)
|
|
- Write test programs to ensure the data is stored correctly
|
|
|
|
RSearch
|
|
-------
|
|
* Test r_search_delta()
|
|
- The pattern finding functions are not following the design
|
|
of the rest of the library, it needs a redesign and code cleanup
|
|
(see bytepat.c)
|
|
- Implement radare/src/xrefs.c into r_search
|
|
- Add support to change the case sensitive of searchs (ignore case)
|
|
- This must be keyword-based. Not globally
|
|
- Sync vapi (r_search_regexp not implemented)
|
|
- Enable/disable nested hits? (discuss+ implement in parent app?)
|
|
- Just skip bytes until end of keyword
|
|
* AES/RSA Key finding
|
|
http://citp.princeton.edu/memory/code/ <- implement this stuff in r2
|
|
|
|
|
|
Binaries
|
|
--------
|
|
* add support for .a files (r_fs supports cpio and ar archives...)
|
|
* add support for .rar files
|
|
|
|
# Random
|
|
* Implement rap:// upload/download protocol commands (maybe just system() with rsc2+wget?
|
|
* Reimplement or fix the delta diffing in C - first we need to do it for ired..
|
|
* Ranged/scrollable zoom mode
|
|
|
|
* Add support for STATIC_PLUGINS in r_lang
|
|
- r_lang_define is implemented in lang.c, but requires the collaboration
|
|
of the plugins to properly setup the environment for the script execution.
|
|
- Add support for STATIC_PLUGINS in r_lang
|
|
- dlerror(/usr/lib/radare2/lang_perl.so): libperl.so: cannot open shared object file: No such file or directory
|
|
This issue is fixed by setting LD_LIBRARY_PATH...looks like dlopen ignores rpath
|
|
* gdiff
|
|
- graph based fingerprints? (cyclomatic complexity...)
|
|
* rcore
|
|
- do not allow to disassemble unaligned addresses (toggle)
|
|
- r_asm can reduce cpu without disasm on fixed size ops archs.
|
|
* Add support for templates -- like in 010
|
|
http://www.sweetscape.com/010editor/templates.html
|
|
* templates #!template peheader.template
|
|
- pT template.foo # r_print_template
|
|
translate into c code and gets compiled. use rcc+rasm?
|
|
it is like a extended regular expression engine
|
|
|
|
|
|
Debugger
|
|
--------
|
|
* Skip instruction
|
|
* Step until end of frame (stack pointer restored) (store sp, check if nsp>sp)
|
|
* stepover waits for one unknown event that cannot be stopped
|
|
* code injection facilities? (wtf? insert, execute, restore)
|
|
* Trace contents of buffers: filter search results..? cc 8080 @@ hit* .. check for values that has changed.
|
|
* Record trace of register status for each function when running
|
|
- r_reg_arena_copy();
|
|
* Implement list threads on ALL supported platforms (win,lin,osx)
|
|
* All threads must be stopped when a breakpoint is handled..
|
|
* Add support for windbg+virtualkd
|
|
* Floating point registers
|
|
* MMX/XMM/DRX control
|
|
* Implement dump+restore as macros (dump,)
|
|
* Implement software stepping (with code analysis+breakpoints)
|
|
* Implement dbg.bep - in r_core? in r_debug after attach? maybe only in r2 binr?
|
|
- must be refined.. and look for better names
|
|
|
|
pancake
|
|
-------
|
|
* Implement PTRACE_BLOCK on Linux
|
|
* fork/clone child . inject code to create new threads or pids
|
|
* Functions in r_util to get lil/big ut8,16,32 from ut8*
|
|
- already done..must find better names probably
|
|
* rarc2 allows to compile invalid code like calling puts() out of context
|
|
* Implement RAnalCall (analyze function arguments, return values, propagate types..)
|
|
- define number of arguments for given function
|
|
- warn if signature and analysis differs in number of args or so..
|
|
- when calling a function
|
|
- identify arguments passed and compare with arguments required
|
|
- if they do not match: we need to warn/ask user/store multiple options
|
|
- function signature comparsion if they dont match
|
|
r_anal_fcn_cmp (anal, f1, f2);
|
|
|
|
Analysis
|
|
--------
|
|
* split r_anal API functions (too much args) _new, _add...
|
|
* Initial analysis looking for xrefs to strings and so? ax? ./a@@entry0 - Launched at startup
|
|
|
|
To think
|
|
--------
|
|
* Ranged value:
|
|
- ut64 from, to
|
|
- restrict : %2 (module)
|
|
* Add support for aout binaries?
|
|
* eprintf should be modified to log into a file
|
|
- eprintf_open() -- start log to file
|
|
- eprintf_close() -- stop log to file
|
|
* Only use uppercase KMG for Kilo,Mega,Giga in r_num? - 'g' is for double
|
|
* radare2.c:217 . find name for maxfilesize to hash
|
|
* r_list_foreach_prev is buggy, review and remove..
|
|
* make symstall in r2-bindings/ ?
|
|
* Add deltified offset in PC? +10, +30 ... asm.reladdr
|
|
* regio not implemented // it is really necessary? imho no..
|
|
* distribute 'spp' with 'rarc2' ? imho no
|
|
* Add graph.nodecolor graph.bgcolor graph.edgecolor ??
|
|
|
|
Refactoring
|
|
-----------
|
|
* Rename r_hashtable -> r_ht
|
|
* Review the r_flags api
|
|
* Add pipe_to_buffer..not only file descriptors
|
|
* r_config set_int and so..simplify
|
|
- find/use more common cases for char* or &int maps
|
|
- automatic callbacks for most common usecases
|
|
* Merge r_socket inside r_util ?
|
|
* Is RCore->block and blocksize a RBuf ? refactor!11
|
|
* Discuss missing r_core_sysenv_update in core/file.c:33
|
|
* Add RLog API.. pipeable to disk and stderr..also hookable ..cool for ui (partially done)
|
|
* Redesign core/disasm.c to provide a pluggable api
|
|
* Move 'r_syscall_t' stuff into r_debug (sync r_core)
|
|
* Implement r_bind api to link multiple pointers
|
|
core->asm = r_bind_set (core->asm->bind, r_asm_new ());
|
|
* Find a better name for r_buf_fread (really?)
|
|
|
|
To wipe
|
|
-------
|
|
- Move manpages from man/ to binr/*/? (harder to maintain?)
|
|
- Move the content of libr/*/TODO here
|
|
- linestyle?? for disassembly lines
|
|
- remove libr/vm and libr/db
|
|
- imho we should not implement this:
|
|
- Implement BLOCK in r_core_sysenv_begin|end ()
|
|
* Deprecate CiU (remove) those APIs and dependencies!
|
|
- big-ssl.c big-gmp.c ...
|
|
- implement GMP in util/big.c
|
|
- http://etutorials.org/Programming/secure+programming/Chapter+7.+Public+Key+Cryptography/7.5+Generating+a+Prime+Number+Testing+for+Primality/
|
|
|
|
Optimizations
|
|
-------------
|
|
* Performance
|
|
- cons_visual_write() should do a single write instead of one per line
|
|
- Refactor get_sym() and so on...
|
|
- TODO: make elf/pe get_os() and others return const and not strdup
|
|
- RAnalValue must be static, not ref
|
|
- save memory and accelerate code analysis
|
|
- basicblock signatures must be just pointers to a big buf
|
|
* Optimize /m
|
|
- search only using given file, not loading default library
|
|
- do not read each block byte per byte
|
|
- do not show repeated consecutive hits
|
|
|
|
Future
|
|
------
|
|
* memset0 the op before calling the plugin analysis -- not really that is a performance cost..
|
|
* Add 'S' subcommand to display section size and get by perms rwx
|
|
* Implement r_flag_unset_i () ftw
|
|
* Honor string metadata for asmsteps ('jk' in visual)
|
|
* search.kwidx must be search.lastidx or search.idx ?
|
|
* asm.pseudo for brainfuck
|
|
* code analysis for msil
|
|
* rax2 -k by default?
|
|
* r_cons_visual_write_tail() -> fill end of screen with spaces \o/
|
|
* Add support for 'expect' like foo in rarun2
|
|
- make rarun live in a lib.. or at least be usable from r2
|
|
* use centralized pubsub or memcached to sync data // redis?
|
|
* r_file_slurp should work fine for big files (not prio) r_file_slurp_buf?
|
|
- mmap if supported - add r_file_mmap ? - read file in blocks instead of the whole file in a single syscall
|
|
* Realign flags when using project in debug mode
|
|
* FileDescriptors: dd -- copy from !fd in r1
|
|
* metaflags? support to define relations between flags
|
|
(flag hirearchies)
|
|
r_flagtree
|
|
- r_flags should have a tree construction to access to them faster
|
|
- btree? following pointers like bigger,smaller
|
|
{ struct r_flag_t *bigger, *smaller; }
|
|
- hooks r_flag_add to recalculate in r_flag_optimize(), bigger/smaller pointers
|
|
- hooks r_flag_del to recalculate too.
|
|
- the r_flag_get by string should have another construction with btree
|
|
for the string of the name
|
|
|
|
Threads
|
|
=======
|
|
* implement non-threaded thread api (dummy one, when no support)
|
|
* test w32 port
|
|
* Implement a pure clone(2) backend
|
|
* Added a threading pool super-api
|
|
|
|
# Debug information in binaries
|
|
* dwarf, pdb, def, lib
|
|
- from file, from section, ...
|
|
- load symbols from .lib or .def (find signatures)
|
|
.def -> .idt , .lib -> ar2idt
|
|
* Useful information in the PDB format
|
|
- programming language used (dwarf only?)
|
|
- offset - file:line
|
|
- elements { position, type, name, length, offset, delta }
|
|
- types // using the r_anal vartype API (not yet implemented)
|
|
- position = { inlined, global, local } enum
|
|
- function = { visibility, position, type, calltype (cc), arglist, return }
|
|
- visibility = { local, exported, qualified }
|
|
Types {
|
|
// element types
|
|
array, bitfield, class, struct, union, enum, pointer
|
|
procedure, function, arglist, vtshape, fieldlist
|
|
|
|
// data types
|
|
float, char, signed short, bool, address, ..
|
|
}
|
|
Type {
|
|
char, short, ushort, long, ulong,
|
|
}
