Full Text Bug Listing

I've attempted to emerge pike 5 times now. Each and every time, even after
emerge sync, pike build fails. I've got hardened toolchain and kernel, not sure
if this affects things, but I attempted CFLAGS="-fno-stack-protector" and the
build still failed.

this does a simple check to see if the particular kernel is a hardened kernel. the problem is that when compiled --with-machine-code, pike trips PAX and is SIGKILL'd

if pike is build --without-machine-code it seems to run just fine on a PAX enabled kernel. If you can find a more elegant way of doing the same thing, please do, my ebuild is just a dirty hack to make it work right.

I found a more elegant way to do it:

btw. can you try without Nettle support (-crypt in USE)?
Just so we know it's only the Nettle part of Pike that is causing this problem...

I didn't have time to set up a hardened toolchain yet, I hope someone from our hardened team can look at this.

and the URL with the build log seems to be down, can you host it somewhere else
or attach to this bug?

change PaX flags on pike binary right after building it

skeleton patch to change PaX flags on the newly build pike binary, we'll need
to figure out what flags to set (just edit the patch, no need for re-diffing
stuff)

Created an attachment (id=50085) [details]
patch with working PaX flags (-pms)

compiles fine, but there's still a grsec message:

grsec: attempted resource overstep by requesting 8409088 for RLIMIT_STACK
against limit 8388608 by
/var/tmp/portage/pike-7.6.24/work/Pike-v7.6.24/build/linux-2.6.10-grsec-i686/conftest[conftest:17691]
uid/euid:0/0 gid/egid:0/0, parent /bin/bash[bash:17690] uid/euid:0/0
gid/egid:0/0

doesn't seem to cause any problems though

if this can be built as to not trigger PaX at all while still keeping PaX
enabled then the hardened team would like to go that route.
IUSE="... hardened"

src_compile() {
..
 use hardened && myconfig="--without-machine-code" \
  || myconfig="--with-machine-code"
}

Please only set PaX flags when we have no other option.

This still happens with pike-7.6.24, compiling --without-machine-code helps.

Fixed in 7.6.24 CVS rev. 1.7; --without-machine-code added when USE=hardened.
No change when not USE=hardened; keywords unchanged.
