I feel like Linux is so incredibly popular that it does make it untrue, similar to the punchline of https://what-if.xkcd.com/49/ >. I use "pushover" because that's what the FSF uses: https://www.gnu.org/licenses/license-compatibility.en.html > > we call them “pushover licenses” because they can't say “no” when one user tries to deny freedom to others.

The point that Theo de Raadt is making is that this line of thinking is wrong*. Most of the FSF/GPL advocates never seem to look at the why's around people disliking their approach. See https://lkml.org/lkml/2007/9/1/102 as an example. OpenBSD helped the Linux project dual license the ath5k driver. They were thanked by GPL advocates illegally trying to strip the BSD license after the fact. Leaves a bad taste, and one…

Theo de Raadt is the one who's wrong. When code goes closed source, you're locked out and can't have it at all anymore. When it goes GPL, you can still have it just by going GPL yourself.

They maintained apache 1.x in base for a long time. For a small number of releases they switched to nginx and then i think they wrote their own.

Parent is referring to the Apache 2 license, not version 2 of the Apache HTTPD server.

I'm pretty sure parsing ELF binaries is out of scope for kdump(1), sorry, but I don't think that's going to happen. It's not that difficult to run addr2line yourself with the information provided, and that's really for the best.

You are arguing for a worse UX because of an arbitrary reason. Just link against the code in addr2line. Providing a good UX should always be in scope for a project.

To quota GNU libc manual: > There is no point in freeing blocks at the end of a program, because all of the program’s space is given back to the system when the process terminates. https://www.gnu.org/software/libc/manual/html_node/Freeing-a... I think many GNU tools just never free any memory. For example, GCC : https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66339 -- edit: added GCC as example.

The last time I used a leak finder, a memory allocation which still has a ptr to it is not a leak. You are conflating unfreed memory with unreferencable memory.
