Package: prosody [0.9.12]

For existing package:

• expected behavior: it runs.
• actual behavior: Segmentation fault.

Platform:

ASUS RT-N16 (MIPSR2 K26) with Tomato by Shibby 1.28.

Prosody is a Lua application, but Lua itself seems to be running fine, so I can't quite tell where exactly is the issue without debugger facilities. I had to build Prosody from sources myself (ugh...), and this one that I built runs just fine right now (same 0.9.12 version). I used this toolchain (it comes with Linux binaries), if that helps.

/opt/bin/prosody & /opt/bin/prosodyctl have incorrect shebang. This will be fixed. No segmentation fault when running prosody on a mipsel router with 3.4 kernel. Probably your kernel version is too old.

What firmware are you running? I still see Tomato project sticking with ancient 2.6 kernel. He backports some features though.

Probably your kernel version is too old.

It definitely is. I believe it's rather a subtle libc issue though. After all, the exactly same version built with Tomato toolchain does work without issues, and I built it with even more stuff (libevent, sqlite db support) than opkg provided version.

What is weird is that you'd expect everything else installed by opkg to randomly segfault, but no other installed package shows any sign of crashes: I tested NGINX, PHP 7, node.js, transmission, git, etc.

This is not a Broadcom based router.

shebang is fixed via https://github.com/Entware-for-kernel-3x/entware-packages-3x/commit/5d65e6da8a15cc1eb57eb4d600d5b6f1f38bc13e It will be in entware-ng soon

It seems that issue still actual. I'm catching "Segmentation fault" at Asus RT-N65u with 3x kernel and prosody_0.9.12-1a_mipselsf "

I strongly recommend to install Entware-3x on Padavan firmware https://github.com/ProBackup-nl/Entware-ng-3x/wiki/Install-on-Padavan

You will need to create user/group to run prosody

 # prosodyctl start
Warning: Couldn't switch to Prosody user/group 'prosody'/'prosody': no-such-group

No segmentation fault here!
