linux-grsec's Issues

-fstack-protector-strong not supported by compiler

Despite gcc not protesting when compiling a sample program with the option -fstack-protector-strong, while building linux-grsec it complains about the aforementioned option.

Same happens when building from Arch Linux community repository.

I don't know if I didn't realize it before or if it's a new error.

This issue refers (at least) to 0d6b88f (linux 4.5.7, grsec 3.1/201606110914).

More of a question than an issue

I've been building my own grsecurity kernel for about a year that I forked from you.

Since ~4.8.10 or so, I've had regular boot issues. In particular, issues with systemd-logind repeatedly mounting and unmounting a tmpfs, then failing. After doing so thousands of times, it eventually failed and the computer hangs. I tried installing your precompiled package from the repos, and it booted fine. I then basically started moving my config closer to yours in groups of ~10-20 flags at a time. In the end, it seemed more random than anything. Some would boot, some wouldn't. My last one from the 22 Feb patchset booted, with all of my config switches identical to yours save a few in the grsecurity patch set. Now, in the 5 March patch, I once again cannot boot.

I've already reached out on the grsecurity forums, but since many users are on gentoo and other distros, I thought I'd see if you've had any similar issues and/or any advice.

Thanks so much for your time!

Error with Virtualbox and VM with VT-x enabled

Hello,

I'm not sure if this is the right place to ask.
I installed linux-grsec, added pax_nouderef as a kernel parameter because I have a sandybridge cpu and it wouldn't boot otherwise.
Besides that I didn't change anything else.
Everything works fine except from VirtualBox where the application itself starts but if I try to start a VM that has the VT-x acceleration enabled in its settings it will throw the error pasted bellow. If I disable VT-x it starts fine but of course works much slower.
Am I doing something wrong?

I tried setfattr -n user.pax.flags -v "mr" /usr/lib/virtualbox/VirtualBox as well but that didn't change anything.

Cheers and thx for maintaining the packet :)
