Description Dmitry Butskoy 2006-07-17 14:05:23 UTC 
Description of problem:
There are some unexpected kernel-API changes in 2.6.17-1.2157_FC5.

Compare file "include/linux/skbuff.h" from kernel-devel-2.6.17-1.{2139|2145} and
from 2157. At least "struct skb_shared_info" was changed (tso_size --> gso_size
etc.)

Some 3rd-party network card modules cannot be compiled easy any more because of
this.

IMHO it is not a good idea to do any API changes in the *same* kernel version
(2.6.17).

As these changes was for support Xen kernels only, maybe #ifdef them someway?



Version-Release number of selected component (if applicable):
2.6.17-1.2157_FC5
Comment 1 Dmitry Butskoy 2006-07-17 14:10:17 UTC 
Additional info:

The changes was inspired by the newest linux-2.6-xen.patch ...
Comment 2 Dmitry Butskoy 2006-07-27 11:36:05 UTC 
"gso_size" above appears in 2.6.18 ...


It seems that linux-2.6-xen.patch was generated by running "diff" with the
2.6.17 source and some Xen-modified 2.6.18 source (instead of some "Xen-modified
2.6.17 source").
Comment 3 Dave Jones 2006-09-11 01:46:45 UTC 
There is no stable kernel API across releases upstream, and hence, there isn't
one in Fedora either.
