disconnect3d	86e4679f79	add show-flags and show-compact-regs to ctx regs banner ... Hopefully his will improve the discoverability/UX for users who are not aware of those options. This is how the new registers banner looks like: ``` [ REGISTERS / show-flags off / show-compact-regs off ] ``` Fwiw it is 54 chars long (without "---" before and after) so its length should be fine.	3 years ago

disconnect3d	b209ada229	Fix disable_colors formatting & test ctx disasm showing fds ... This commit adds a test for context disasm showing of file descriptors file paths in syscalls like read() or close(). It also fixes a small issue when Pwndbg is run with PWNDBG_DISABLE_COLORS=1 This issue was that executing: ``` pi '{a:2}'.format(a=pwndbg.color.context.prefix(pwndbg.config.code_prefix)) ``` Failed when Pwndbg was run with disabled colors. It failed because our generate color functions in pwndbg/color/* ended up not processing the input argument -- which here is a Pwndbg config Paramater object -- so that we got a very non obvious exception: ``` Exception occurred: context: unsupported format string passed to Parameter.__format__ (<class 'TypeError'>) ``` This issue could hypothetically also exist if our config value would be empty I think. So with the fix in this commit, where we do str(x) over the color funciton argument should fix this issue in all cases.	3 years ago

disconnect3d	1ca4d2d33c	Enhance heap with for static-linked binaries & remove typeinfo bloat ... This commit enhances the heap commands UX for statically linked binaries and removes typeinfo module bloat. The typeinfo module had this typeinfo.load function that was looking up a given type. If it didn't find the type, it fallbacked to compiling many many system headers in order to add a symbol for a given type into the program. This was supposed to be used for missing glibc malloc symbols like malloc_chunk. However, the exact reason it was used: the struct malloc_chunk was never defined in a header file and was always defined in a malloc.c or another .c file in glibc sources. Another place the typeinfo.load logic of compiling headers was/is used is the `dt` command, which is a windbg alias for getting struct layout type information, e.g.: ``` pwndbg> dt 'struct malloc_chunk' struct malloc_chunk +0x0000 mchunk_prev_size : size_t +0x0008 mchunk_size : size_t +0x0010 fd : struct malloc_chunk * +0x0018 bk : struct malloc_chunk * +0x0020 fd_nextsize : struct malloc_chunk * +0x0028 bk_nextsize : struct malloc_chunk * pwndbg> ``` However, the whole big issue with typeinfo.load compilation of headers was that most of the time it didn't work because e.g. some headers defined in other paths were missing or that two different headers used the same struct/function name and the compilation failed. Since this logic almost never gave good results, I am removing it. Regarding UX for statically linked binaries: we use `info dll` command to see if a binary is statically linked. While this method is not robust, as it may give us wrong results if the statically linked binary used `dlopen(...)` it is probably good enough. Now, if a heap related command is executed on statically linked binaries, it will inform the user and set the resolving of libc heap symbols via heuristics. Then, it also says to the user they have to set the glibc version and re-run the command.	3 years ago

disconnect3d	3b2f7796d6	Fix #1165: set context-clear-screen on resetting scrollback ... This commit tries to fix the issue of our `set context-clear-screen on` option resetting the scrollback buffer on some terminals like gnome-terminal (fwiw it did not happen on terminator or on tmux). It also adds info to tips about that option.	3 years ago

Albert Koczy	9e84c18c44	fix: mprotect command and add tests for it ... Turns out the mprotect command didn't ever work, as it was amd64 only, but used x86 syscall numbers to call mprotect. I have refactored the command to use shellcraft to generate the shellcode that calls mprotect. I have also unit-tested this command.	3 years ago
