When trying to emerge bestcrypt the compile stage returns the error: i686-pc-linux-gnu-gcc -c -D__KERNEL__ -DMODULE -I/usr/src/linux/include/asm/mach-default/ -D_NEED_THIS_MODULE -I/var/tmp/portage/bestcrypt-1.6_p5/work/bcrypt/mod/../include/ -I/usr/src/linux/include/ -march=pentium4 -O3 -pipe -mmmx -msse -msse2 -fomit-frame-pointer -fno-stack-protector-all -fno-stack-protector -DKBUILD_BASENAME=\"BestCrypt\" -DKBUILD_MODNAME=\"bc\" -D_KBUILD_QUOTES -o bc_dev26.o bc_dev26.c cc1: error: unrecognized command line option "-fno-stack-protector-all" make: *** [bc_dev26.o] Error 1 make: Leaving directory `/var/tmp/portage/bestcrypt-1.6_p5/work/bcrypt/mod' !!! ERROR: app-crypt/bestcrypt-1.6_p5 failed. Call stack: ebuild.sh, line 1539: Called dyn_compile ebuild.sh, line 939: Called src_compile bestcrypt-1.6_p5.ebuild, line 66: Called die !!! compile failed !!! If you need support, post the topmost build error, and the call stack if relevant. I remebered reading in forums that stack-protectors have changed in gcc-4.1.1 so changing the ebuild to: # Don't put stack protection in the kernel - it just is bad - append-flags -fno-stack-protector-all -fno-stack-protector + append-flags -fno-stack-protector allows it to at least compile cleanly. Testing the new module has so far not thrown up any errors.

FWIW... so far 4 days of pretty solid testing with 2.6.16-gentoo-r7 and the slightly modified ebuild in #1 has not turned up any problems *at all*. Container creation with all algorithms works perfectly. Hidden containers work. Mounting, umounting and fsck after a forced unmount work as expected. Multiple containers have been mounted at the same time. Mount after a trialled power failure recovered as would be expected. All other ancillary functions work as expected. Alot of data has been copied in and out and between containers without any loss. Containers in files plus block devices on HDD and removable media (LS-120) have been tested. I am now going back to normal light use.
I did it slightly differently to maintain compatibility with gcc-3* users. I needed to remove -Werror from the CFLAGS for the kgsha{,256} directories otherwise I got the following warnings (treated as errors). Hopefully there is no effect with this. >>> Unpacking BestCrypt-1.6-5.tar.gz to /var/tmp/portage/bestcrypt-1.6_p5/work >>> Unpacking bcrypt-rc6-serpent.diff.gz to /var/tmp/portage/bestcrypt-1.6_p5/work * Applying bestcrypt-1.6_p5-makefile_fix.patch ...
