Bug 42101 – gentoo-2.4.20-r13 has undefined reference to proc_mm_get_mm in sys_ptrace

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Holly 2004-02-18 17:58:44 UTC]

make bzImage complains about an undefined reference to "proc_mm_get_mm" in function "sys_ptrace".
i'll append the kernel .config soon.
the config is the same as i used with -r10. i just ran "make oldconfig" and went on with "make dep && make clean bzImage modules modules_install".

Reproducible: Always
Steps to Reproduce:
1. make bzImage
2.
3.

Actual Results:

If you enable CONFIG_PROC_MM it should go away.

Patch

This should solve it, the other option is to enable CONFIG_PROC_MM or to apply
this patch. If you could confirm this works, I'll add this to
gentoo-sources-2.4.20-r12 along with the grsec fix. Thanks.

- enable CONFIG_PROC_MM: works
- disable CONFIG_PROC_MM and apply patch: works
Thanks!

Fixed in CVS in -r13 along with #42141, should hit Portage within an hour. Thanks.
