Yes, I did start that lovely thread on this issue. Nobody took me up yet on leading a project to get the api seperated from kernel stuff as suggested (a bit later in the thread than the 'sanitized' crap). For now whoever should please just apply the following patch to 2.5 kernels: ---------------------------------------------------------------------- --- linux-2.5.69-bk13/include/linux/sysctl.h 2003-05-19 22:29:18.000000000 +0200 +++ linux-2.5.69-bk14/include/linux/sysctl.h 2003-05-20 21:42:20.000000000 +0200 @@ -35,6 +35,10 @@ the largest acceptable value for the nlen member of a struct __sysctl_args to have? */ +#ifndef __user +#define __user +#endif + struct __sysctl_args { int __user *name; int nlen;
az seems to have provided the fix. closing.
That's not a real fix - it's a hack, what we need is to get an API to communicate with the kernel instead of using the kernel headers but this is not for Gentoo to fix.
agreed - i should have used "workaround"... nonetheless, this bug can be closed.
