[Jamvm-general] Executable stack markings on libjvm.so

[Andrew H. <gnu...@re...>]

Hi,

Because of the use of assembly code for callNative.S, gcc marks
the resulting object files as having executable stack. This leads
to libjvm.so being marked as such, and problems ensue when using
the library on hardened kernels.

IcedTea has been working around this for a while by passing
--noexecstack to the linker without problem. The attached patch
fixes the issue at its cause, adding the appropriate markings [0]
in the assembly code.

Please apply this patch to JamVM.
