grsecurity forums

Hi.

I'm using a debian system with an grsecurity 2.0-rc3 enabled 2.4.22 kernel, gradm is version 2.0-rc3.
grsecurity for itself runs fine.
Recently i updated libc6 from 2.3.2-7 to 2.3.2.ds1-10.
I tried to compile gradm after the update.
It gave me the following error:

[...]
/usr/include/linux/compiler.h:17: warning: `__attribute_used__' redefined
/usr/include/sys/cdefs.h:195: warning: this is the location of the previous definition
gradm_res.c: In function `add_res_acl':
gradm_res.c:143: `NR_OPEN' undeclared (first use in this function)
gradm_res.c:143: (Each undeclared identifier is reported only once
gradm_res.c:143: for each function it appears in.)
make: *** [gradm_res.o] Error 1

This shows up with gcc 2.95.4 as well as with gcc 3.3.2.

did i forget something while updating libc6?
the old gradm-binary does run fine with the new libc, i just can't compile.

thank you for you time/help

add #include <linux/limits.h> to gradm.h

it's fixed in current CVS.

Thank you for the help.

I have the follwing:
Debian unstable uptodate
gradm-2.0-rc3
grsecurity-2.0-rc3-2.4.22
Kernel: 2.4.22

And i added #include <linux/limits.h> to gradm.h

I still get the same error:
---------------------------------------
/usr/bin/gcc -O2 -DGRSEC_DIR=\"/etc/grsec\" -c -o gradm_res.o gradm_res.c
gradm_res.c: In function `add_res_acl':
gradm_res.c:143: error: `NR_OPEN' undeclared (first use in this function)
gradm_res.c:143: error: (Each undeclared identifier is reported only once
gradm_res.c:143: error: for each function it appears in.)
make: *** [gradm_res.o] Error 1

Any ideas?
Thanks, Mario

I've got the same problem with Debian sid (testing). The NR_OPEN is solved by adding #define NR_OPEN 1024 to gradm.h, but then it gives a new set of errors:
