Unhandled relocation type of 'R_X86_64_IRELATIVE'

[Deepak Krishnan]

Hi,

I was playing around with OSv and came across an .so file with a ''R_X86_64_IRELATIVE' entry in PLTGOT - which seems to be crashing OSv because of this assert in core/elf.cc:relocate_pltgot() : assert(type == ARCH_JUMP_SLOT || type == ARCH_TLSDESC)

The binary itself seems to have been built using GCC 7.3.0 and isn't anything special as far as I can see. What's the reason behind the assert there? Is an IRELATIVE type relocation not expected or is it simply unhandled?

Thank You in advance.

Hi,

Yes indeed OSv does not support this relocation at this time. 

However I am working on the changes to support static executables that include adding support of these relocations. I should be sending corresponding PR soon. 

Regards,

Waldek

Hi,

I have created a pull request that should address this - https://github.com/cloudius-systems/osv/pull/1245. Please give it a try and let me know.
