Hi

I have tray install grsecurity to linux debian on the architecture sparc64
TI UltraSparc II

When I compiled the kernel , I got error

CC arch/sparc64/mm/fault.o
arch/sparc64/mm/fault.c: In function `do_sparc64_fault':
arch/sparc64/mm/fault.c:699: error: label `fault_done' used but not defined
make[2]: *** [arch/sparc64/mm/fault.o] Błąd 1
make[1]: *** [arch/sparc64/mm] Błąd 2

In file fault.c in 699 line is:
goto fault_done;
I can't find this function "fault_done" in all files kernel source.

looks like you're the first ever to try 2.6-grsec on sparc64 ;-)

. the following patch should fix up this bitrot (may apply with some offset on 2.6.14):

Thx it's working but now I have new problem, when I run gradm -E
I have get this messages

gradm -E
You are using incompatible versions of gradm and grsecurity.
Please update both versions to the ones available on the website.
Make sure your gradm has been compiled for the kernel you are currently running.

kernel currently runing - 2.6.14.6

gradm - gradm-2.1.8-200601212342.tar.gz

Maybe it's a problem , when I changed this ?:

Any ideas?

P.S It's working when installing libc6-dev-sparc64 (apt-get install libc6-dev-sparc64)

gradm is built as a 64 bit application (vs. a more usual 32 bit one) hence you need the 64 bit libc to link against, as you found it out apparently ;-)
