But, the error you're getting normally indicates that CONFIG_SECURITY_CAPABILITIES was not set to "m". Did you set these? CONFIG_MODULES=y CONFIG_MODULE_UNLOAD=y What does `grep Realtime /var/log/messages' say after modprobe fails? > When building LSM, I wasn't able de run make as a user : > > $ make > CONFIG_SECURITY_CAPABILITIES=m > make modules -C /usr/src/linux SUBDIRS=/home2/al/realtime-lsm-0.1.0 > make[1]: Entering directory `/usr/src/linux-2.6.5' > *** Warning: Overriding SUBDIRS on the command line can cause > *** inconsistencies > make[2]: `arch/i386/kernel/asm-offsets.s' is up to date. > CC [M] /home2/al/realtime-lsm-0.1.0/realcap.o > CC [M] /home2/al/realtime-lsm-0.1.0/commoncap.o > LD [M] /home2/al/realtime-lsm-0.1.0/realtime.o > /bin/sh: line 1: .tmp_versions/realtime.mod: Permission denied > Building modules, stage 2. > MODPOST > /bin/sh: line 1: ./.__modpost.cmd: Permission denied > make[2]: *** [__modpost] Error 1 > make[1]: *** [modules] Error 2 > make[1]: Leaving directory `/usr/src/linux-2.6.5' > make: *** [all] Error 2 > > But it works when make is run as root. The README file says that only make > install has to be run as superuser. The way the Makefile currently works, it needs write access to the kernel build tree. I'll update the README to make that clear. I hope some day we will figure out a way to avoid modifying the kernel build tree. -- joq
