Arch Linux

Yes, it builds; I forgot to upload the AURball.

https://grsecurity.net/~paxguy1/pax-linux-3.16.1-test2.patch

This should hopefully fix the compilation problems.

Hi, is anyone able to build this? Whenever I try, it stops at:

Aborting...

I also have this with my linux-ck-pax package at the same point.

Nice tip, thanks very much.

For when that happens it'd be better to preserve the latest working patch and just put that in the $srcdir instead of simply breaking the whole thing - even if not by your fault.

E: Actually it seems at least some of these are stockpiled in http://grsecurity.net/~paxguy1/. Might also be a better place to get the patch from because I don't know where are you getting the current link from in the new site.

3.11-test7 is still not booting, do not upgrade, yet.

3.11-test2 did not boot at all, 3.11-test3 did but both on x86_64 and i686 hardware and vms, very much errors showed up at boot. I uploaded the current PKGBUILD, but be warned.

SOLVED - Binary kernel from arsch for the Kontact Portion.
Note Kile is still seg faulting. Notes at bottom.

Valgrind for Kontact

[daipengg@gurka ~]$ valgrind kontact
==46753==
==46753== Valgrind's memory management: out of memory:
==46753== newSuperblock's request for 4194304 bytes failed.
==46753== 69898240 bytes have already been allocated.
==46753== Valgrind cannot continue. Sorry.
==46753==
==46753== There are several possible reasons for this.
==46753== - You have some kind of memory limit in place. Look at the
==46753== output of 'ulimit -a'. Is there a limit on the size of
==46753== virtual memory or address space?
==46753== - You have run out of swap space.
==46753== - Valgrind has a bug. If you think this is the case or you are
==46753== not sure, please let us know and we'll try to fix it.
==46753== Please note that programs can take substantially more memory than
==46753== normal when running under Valgrind tools, eg. up to twice or
==46753== more, depending on the tool. On a 64-bit machine, Valgrind
==46753== should be able to make use of up 32GB memory. On a 32-bit
==46753== machine, Valgrind should be able to use all the memory available
==46753== to a single process, up to 4GB if that's how you have your
==46753== kernel configured. Most 32-bit Linux setups allow a maximum of
==46753== 3GB per process.
==46753==
==46753== Whatever the reason, Valgrind cannot continue. Sorry.

I uploaded the new PKGBUILD a little hasty. The 3.8.2-test5 patch has problems with sysfs. Latest working patch is 3.8-test3 (linux-pax-3.8-3). It is current in arsch.orgizm.net and 619af646faa69e2a79c7982c0dd426cf56b9de80 in "git://git.orgizm.net/collective.git".
