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

Disconnect3d	cc3f86d5bc	Improve vmmap on coredump files (#1149) ... * Improve vmmap on coredump files With this commit we now recognize coredumps better and also finally have a simple test for vmmap commands on: - a running binary - on a loaded coredump file with loaded binary - on a loaded coredump file without a loaded binary We also stop saving vmmaps for `maintenance info sections` sections which have a start address of 0x0. While there could potentially be a coredump file from a binary with start=0x0, this should work in most cases. We could in theory do a slighty better: we could take the vmmap at 0 and try to read memory from it. However, I am not sure if it is a good idea to try such memory read? * remove unused import * add missing crash_simple.asm * fix vmmap coredump test on different ubuntu mem layouts * use /proc/$pid/maps for vmmap tests * fix formatting * fix import * fix test * fix test * fix test * fix lint * fix test * fix test * fix test * fix test * fix lint * another fixup for ubuntu 22.04 * another fixup for ubuntu 22.04 * lint	3 years ago
CptGibbon	636db8b25f	Add regression test for `find_fake_fast` command (#1147) ... * Add a regression test for find_fake_fast The test program creates a fake chunk size field in its .data section with a set NON_MAIN_ARENA flag. The Python test runs the find_fake_fast command on an address succeeding the fake chunk. A gdb.MemoryError indicates regression - issue #1142 * Make linter happy	3 years ago

Disconnect3d	b7ddf3a070	fix #1111 errno command edge case (#1126) ... * fix #1111 errno command edge case This commit fixes the case when errno command causes a binary to segfault when the `__errno_location` symbol was defined but its .plt.got entry was not filled yet by the dynamic loader (ld.so), so e.g. when the glibc library was not loaded yet. In such a case, us triggering a call to `__errno_location` function triggered a jump to an unmapped address. Now, we dereference that .plt.got symbol and see if it lives in mapped memory. * add tip about errno command * errno: fix case when __errno_location@got.plt is missing * fix lint * fix sh lint * fix errno test	3 years ago

Artur Czepiel	4ee225b115	Make ZIGPATH configurable and provide defaults (#1090) ... * Make ZIGPATH configurable and provide defaults Mostly fixes docker/docker-compose environment where building zig into $pwd/.zig doesn't work well because it is later overwritten by mounting the volume in /pwndbg. With current approach during the docker build zig is put in /opt/zig instead, and when you run it without docker it's possible to configure a different path (with sane defaults) * remove Makefile * add ZIGPATH to tests.sh for CI * move ZIGPATH setting before make in tests	3 years ago

Disconnect3d	1d70e14418	Fix #932,#788: fix command parsing ... When we moved to argparse command parsing we introduced `gdb_sloppy_parse` which wasn't perfect: e.g. for `gdb.parse_and_eval("__libc_start_main")` would return a `gdb.Value()` whose `.type.name` was `long long`. As a result when code that used `gdb_sloppy_parse` then casted the result to `int(gdb_value)` it crashed because for some reason GDB errored. This commit fixes the issues related to it by adding `AddressExpr` and `HexOrAddressExpr` functions. It also adds tests for some of the windbg compatibility commands and fixes some nifty details here and there.	4 years ago
