Package: user-mode-linux
Version: 2.4.18.17um-1
Severity: normal
Tags: patch
The source of user-mode-linux 2.4.18.17um-1 (current stable uml) when
applied to kernel-source-2.4.18_2.4.18-9 (the current stable kernel
source) produces a kernel that can not be compiled:
gcc -D__KERNEL__
-I/root/installs/user-mode-linux-2.4.18.17um/kernel-source-2.4.18/include
-Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fomit-frame-pointer
-fno-strict-aliasing -fno-common -U__i386__ -Ui386 -DUM_FASTCALL
-D__arch_um__ -DSUBARCH=\"i386\" -DNESTING=0 -D_LARGEFILE64_SOURCE
-I/root/installs/user-mode-linux-2.4.18.17um/kernel-source-2.4.18/arch/um/include
-Derrno=kernel_errno -c mk_task_kern.c
In file included from mk_task_kern.c:1:
/root/installs/user-mode-linux-2.4.18.17um/kernel-source-2.4.18/include/linux/sched.h:799:
conflicting types for `kernel_thread'
/root/installs/user-mode-linux-2.4.18.17um/kernel-source-2.4.18/include/asm/processor-generic.h:95:
previous declaration of `kernel_thread'
make[1]: *** [mk_task_kern.o] Error 1
...
It seems that as of kernel-source-2.4.18_2.4.18-9 there is a generic
kernel_thread() defined in kernel/fork.c (line 557) and the architecture
speciffic implementation is left for arch_kernel_thread() - function
defined in arch/um/kernel/process_kern.c and declared in
arch/um/include/asm-um/processor-generic.h
Here is a patch that can be applied to uml-patch-2.4.18-13
(compressed in uml-patch-2.4.18-13.gz and part of the source
package):

After appluing this patch I was able to recompile and use uml.

Dear all,
since 2.4 u-m-l support is no more available in the upcoming releases,
I should say that the bug #200325 can be closed.
Cheers
