OpenAFS Gurus,
I spent a few hours today playing with Phoebe (the new beta
from Redhat), trying to get OpenAFS 1.2.8 to work. I started with the
RedHat 8.0 source RPMS from www.openafs.org. I've run into a few
problems that I was able to solve, but could use a quick hand with a
subject everyone on this list is rapidly becoming experts at - Linux
syscalls. First, the problems I've been able to solve.
=20
#1 - The first problem was the well documented issue of
src/pam/Makefile.in and the extra -I/usr/include line. This is already
fixed in CVS, so I just deleted the line on my local copy and re-ran
configure.
#2 - The second problem was the also documented problem with errno.h.
The two files that need errno.h included are src/sys/rmtsyss.c and
src/ptserver/pt_util.c.
#3 - Third, it seems some of the external functions OpenAFS use changed
names. To start with, recalc_sigpending() no longer takes any arguments;
it is assumed you want to act on the current task. If you want to act
on something other than the current task, you need to use
recalc_sigpending_tsk(task); Second, for_each_task() (a #define from
sched.h) changed names to for_each_process().
#4 - The names of some of the members of struct task changed. The
changes that affect OpenAFS are (I think I got this right - I had to do
some searching to find out):
sigmask_lock became sig->siglock
p_pptr became parent
p_opptr became real_parent
=20
With those four items fixed, I was able to build and install OpenAFS.
And then I tried to load it, and wouldn't you know it....
=20
libafs-2.4.20-2.2-i686.o: unresolved symbol sys_open
libafs-2.4.20-2.2-i686.o: unresolved symbol sys_exit
libafs-2.4.20-2.2-i686.o: unresolved symbol recalc_sigpending_tsk
libafs-2.4.20-2.2-i686.o:=20
Hint: You are trying to load a module without a GPL compatible license
and it has unresolved symbols. Contact the module supplier for
assistance, only they can help you.
=20
I know these needs to be fixed in osi_module.c, but I got lost in that
file. I'm giving up and going home.
=20
To help anyone else out who wants to work on this over the weekend, I'm
attaching my patches that apply cleanly to a fresh OpenAFS 1.2.8 Redhat
8.0 .src.rpm. The two patches are:
=20
Openafs-errno.patch - Includes the fixes for problems #1 and #2 listed
above. You can cleanly and safely apply this patch to any install.
Openafs-kern-struct-change.patch - Includes the fixes for problems #3
and #4 above. This patch is very specific to kernel 2.4.20 (and maybe
2.4.19). I haven't wrapped any of the functions with an #ifdef
NEW_LINUX_NAMES or anything like that, so once you install this patch on
your source tree you will be unable to compile OpenAFS for any other
kernels.
=20
Hopefully, someone on this list will find the info useful, and they will
be able to get OpenAFS working on Phoebe.
Sean
