0.9.4
=====
* rap:/ doesnt works at all
tothink:
* Event system . allow to send and read queues of messages.. thats pubsub!
* search for CALL instructions in text segment.
- analyze the destination address of each call destination
* Analysis: assume there is a function at the end of each function
* Integrate dwarf parser with disassembler and debugger
* Step back .. log all state changes on every debugger stop
* Show analized functions in 'aa' -> discuss
* Timeout for code analysis (check timestamp)
* Allow to seek to branch N like in visual, but from cmdline
* Colorize multiple ranges of chars in hexdump
* Insert assembly in visual should be more userfriendly (keep unwritten bytes)
* refactor vmenus.c -> refresh function must be redefined for each menu
// show hints for
0x100005eca ff2540130000 jmp qword [rip+0x1340] [1]
* Fix ?-
* bar for cursor?
* p= show entropy of current block
- show number of occurrences for each byte
- maybe in 'ad' command, analyze data
* highlight search hits in hexdump
* Implement debugger backtrace properly
* _ -> write string does not obeys the cursor
* rep+ret instruction (f3c3) should be identified as RET
* p7 : 7bit encoding (sms)
- variant for stego print? LSB, MSB, ...
- add base85 api
* crackme mach0 happy with rbin
* if no debugger supported, say so... r_io must ?
* check search multiple keywords and signatures
* search for antidebug/disasm tricks opcodes
- allows to find interesting points to analyze
* use slices for r_list_iter primitives
BUGS
----
* If [0-9] keybindings in visual point to same address use same reference
* RBinCreate:
- mach0 create for darwin-ppc
- mz
- pe64
- plan9 bins
* Add !load in r2 (oo args)
* opening a file from inside r2 doesnt clears internal data (strings..)
* 'ao' must be for opcodes, not bytes
* backtrace for linux or osx at least
* implement 'ax' to get/set xrefs (better than afl ) .. 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
* implement aoe = anal op exec
- sync regs or what?
* 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 /p to search for patterns
- implement it in r_core ?? or add r_io_bind support
* 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
--------
* DEX parsing fail (invalid offset of symbols)
* add support for .a files (r_fs supports cpio and ar archives...)
# 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/ ?
* What about rsc2 ? deprecate, maintain? cleanup from 1? build? install?
* 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
-----------
* move r_th into r_util
* Merge javasm code (asm, bin -> shlr)
* Rename r_hashtable -> r_ht
* Remove/deprecate libr/vm
- Make ht64.c include ht.c
* 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?
* Merge libr/db inside libr/util ?
* implement code analysis using udis86.. is this necessary.. x86im works fine?
* 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
* acr -ldl check must be fixed for kfreebsd
* 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,
}
