Hello,
I asked over on 'users' a few days ago and no help yet. I hope you
don't mind my repeating the question here.
We're a small company using some altera-based boards and our own
driver to control them.
Fedora 7 was working well, but we are getting some unknown symbols
while evaluating an upgrade to F9.
Any help, comments, suggestions are greatly appreciated.

code and issues :
struct sched_param param = {70};
kernel_cap_t effective, inheritable, permitted, all;
cap_set_full(all); // be sure we have enough permissions to call
// sched_setscheduler.
// probably only need CAP_SYS_NICE, but let's be
// "(un)safe"
// save old permissions
cap_capget(current,&effective, &inheritable, &permitted);
// setup permissions to do this
cap_capset_set(current,&all, &all, &all);
// setup realtime priority
ret=sched_setscheduler(current,SCHED_RR,¶m);
// restore permissions
cap_capset_set(current,&effective, &inheritable, &permitted);
used to be able to do this in f7 / 2.6.23 kernel, now we get:
WARNING: "cap_capset_set" [/usr/CSM/src/ONI/oni_driver/oni.ko] undefined!
WARNING: "cap_capget" [/usr/CSM/src/ONI/oni_driver/oni.ko] undefined!
when building and of course:
oni: Unknown symbol cap_capget
oni: Unknown symbol cap_capset_set
when insmod'ing under f9 / 2.6.25
Now if you are writing drivers you are sophisticated users. I would
think you have already tried these, but just in case.
Have you looked on Fedora 7 kernel source to see if that module is there
and if it has those symbols. And read what they do.
Do a find from the top of the kernel source hierarchy on Fedora 9 to
see if oni is still there as a module, just a different path.
find /usr/src -iname "oni*"
Do a search for ONI on the web with linux and kernel to see if you find
anything related to the change.
The linux kernel lists are archived at gmane.org and you can search them
there. You might find messages as to why this was changed and what
replaced it or where it moved.
Post a message on one of the linux kernel lists, preferably the one
relevant to your hardware, asking about this.
