Execstack is a great tool for learning and training on Linux. It is a program which sets, clears, or queries the executable stack flag of ELF binaries and shared libraries. When I was looking to install it I took me a bit to find which package to install it in.
You can install with :
Ubuntu
$ sudo apt-get install prelink
Arch Linux
| from collections import namedtuple, OrderedDict | |
| from functools import partial | |
| # important: pass (name, value) pairs as a tuple/sequence not as keyword args! | |
| # otherwise, order will not be preserved. | |
| fields = OrderedDict((('foo', "bar"), ('spamm', "eggs"), ('ham', None))) | |
| T = partial(namedtuple("T", fields), **fields) | |
| t1 = T() | |
| print(t1) | |
| t2 = T(ham="bacon") |
| all: list | |
| lv2_class: lv2_class.c | |
| gcc -std=gnu99 -O3 -o $@ $< $(shell pkg-config --cflags --libs lilv-0) | |
| list: lv2_class | |
| ./$< \ | |
| | sort \ | |
| | sed 's/,/\n/g' \ | |
