Date: Thu, 13 Dec 2007 19:18:44 -0800 From: Darren Hart <dvhltc@...ux.vnet.ibm.com> To: "lkml, " <linux-kernel@...r.kernel.org> Cc: linux-rt-users@...r.kernel.org Subject: 2.6.24-rc2-rt1 build failure: mod_unreg_security security/realcaps.c still uses mod_unreg_security and unregister_security to try and unregister the realtime capabilities from LSM. Those functions appear to have been removed from security/security.c, so the build fails with: security/realcap.c: In function ‘realtime_exit’: security/realcap.c:129: error: implicit declaration of function ‘mod_unreg_security’ security/realcap.c:133: error: implicit declaration of function ‘unregister_security’ ‘mod_unreg_security’ only exists in the one place and in the lsm.tmpl I compared the security.c of 2.6.23.9-rt12 and it still has the two missing functions. Was there a change in how features are unregistered from LSM that was missed for the realcaps.c file perhaps? I commented out the unreg calls to try and build, it completed, but the realcap.ko had several undefined symbols.
