I realize this problem was likely introduced by upsteam updates, but I
thought I'd point it out here anyway so you're aware of it. An
unintended consequence of this latest kernel update is that it breaks
recompilation of third-party kernel modules. The new kernel was built
with CONFIG_RETPOLINE enabled, so presumably with a compiler that
supports it, but that updated compiler hasn't been released through a
corresponding security ERRATA update. (Not yet, anyway.) When I try to
build a third-party device driver, I get the following error:
make[1]: Entering directory `/usr/src/kernels/3.10.0-693.21.1.el7.x86_64'
arch/x86/Makefile:166: *** CONFIG_RETPOLINE=y, but not supported by the
compiler. Toolchain update recommended.. Stop.
make[1]: Leaving directory `/usr/src/kernels/3.10.0-693.21.1.el7.x86_64'
make: *** [default] Error 2
Is an update of the compiler toolchain for RHEL7/SL7 through the usual
update repos forthcoming? Until then, I don't think I can use this
kernel update on systems that rely on that 3rd party driver.
Thanks,
Gilles
