cannot enable executable stack as shared object requires: Invalid argument

[JMoVS]

• I am trying to get started with linuxbrew on lxss and stumbled into a couple of issues. With this one, the linuxbrew maintainer doesn't have a clue. https://github.com/Linuxbrew/homebrew-core/issues/765
• I'd expect a compilation of ruby to work. Maybe it is dependend on open-ssl having this (might be the case).
• Best and most complete info is in the bottom of the linked thread in the gist - there, pretty much all logs are in there. Also referenced is my original issue at linuxbrew trying to compile openssl.
• Install linuxbrew, set the environment variable to compile everything from source as described here https://github.com/Linuxbrew/homebrew-core/issues/761#issuecomment-239625103
• Strace of the failing command I don't know how to do that.

Thanks for reporting the issue. This is the same as #286 that you commented on earlier so closing this out as a duplicate. Please give us feedback on the user voice page so we can prioritize.

[JMoVS]

are you absolutely sure it is the exact same issue and not just the same symptom?

More seriously though :), the error string above is hardcoded into the glibc loader (see dl-load.c) so I'm pretty sure it's the same issue. If you want to confirm please take a strace and check for a failure with PROT_GROWSDOWN like the other post.

I just ran into this issue when trying to get Swift 3.0.1 running under WSL on Windows 14965.

Had to clear the executable stack flag in libFoundation.so ("execstack -c <pathToSwift>/usr/lib/swift/linux/libFoundation.so"), but once I did that helloworld.swift demo ran using "swift helloworld.swift".

Issue with ansible-vault. Here is the trace stack running Windows 10 Pro Build 15063

@Hickory420 I encounter the same problem with latest version of ansible. Downgrading cryptography fixed this problem for me.
pip install --upgrade --user 'cryptography==1.9'

ansible-vault is now working.

[GiedriusM]

Thanks, @guisea! Running pip install --upgrade --user 'cryptography==1.9' fixed the issue for me too.

The lastest cryptography release can be used, but it needs to be manually compiled:

# Install build dependencies - see https://cryptography.io/en/latest/installation/
sudo apt-get install build-essential libssl-dev libffi-dev python3-dev 
pip3 install cryptography --no-binary cryptography

[phuicy]

This error appears to be fixable, using execstack

sudo apt-get install prelink
sudeo execstack -c /usr/local/lib/opencv.so*

[JianyiH]

I solved that with execstack -c /usr/local/lib/opencv.so*

[sampleref]

I too faced same problem. Error as

"gst-inspect-1.0 dtls

(gst-plugin-scanner:26987): GStreamer-WARNING **: Failed to load plugin '/usr/local/lib/gstreamer-1.0/libgstdtls.so': libcrypto.so.1.1: cannot enable executable stack as shared object requires: Invalid argument

No such element or plugin 'dtls'
"

After giving below, it resolved

execstack -c /usr/local/lib/libcrypto.so.1.1
execstack -c /usr/local/lib/libcrypto.so
execstack -c /usr/local/lib/libssl.so.1.1
execstack -c /usr/local/lib/libssl.so

Hope this helps!
