el5.10 ofed build problem.


I updated to RHEL 5.10 and I’m trying to build ofed modules against the latest 2.6.18-371.1.2.el5 kernel.

./mlnx_add_kernel_support.sh -k 2.6.18-371.1.2.el5 -m /mnt/ofed --make-tgz

Below is the list of OFED packages that you have chosen

(some may have been added by the installer due to package dependencies):

What I’m doing wrong?



I’m having the same problem. Did you fix it yet?



I only have kernel-devel and kernel-headers for 2.6.18-371.1.2.el5 installed, so I don’t think there’s a conflict between different kernels I have installed.

The problem looks like in 2.6.18-371.1.2.el5 they added the definition of netid_is_bond_slave:

static inline bool netif_is_bond_slave(struct net_device *dev)


return dev->flags & IFF_SLAVE && dev->priv_flags & IFF_BONDING;


It doesn’t match the “backported” version in ofa-kernel-1.5.3:


static inline int netif_is_bond_slave(struct net_device *dev)


return dev->flags & IFF_SLAVE && dev->priv_flags & IFF_BONDING;


Same problem here, on RHEL 5.10 x86_64. Looks like the 2.6.18-371 kernel brought some header changes which MLNX_OFED_LINUX-1.5.3-4.0.42-rhel5.10-x86_64 was not prepared for.

Your logs point to conflicts in headers between different kernels you have on the system. Please make sure you install all rpms (including kernel-devel and kernel-headers) corresponding to your target kernel and resolve conflicts before using add_kernel_support (use rpm with “–replacefiles”). Also if you are running add_kernel_support under target kernel (that is what I’d do) you can skip “-k 2.6.18-371.1.2.el5” in command line, it will take “uname -r” value itself.

If you remove the conflicting definition of netif_is_bond_slave from ofa_kernel-1.5.3 (I actually created a kernel_addons/backpoint/2.6.18-EL5.10 directory and modified config.mk) it will build OK.

Going to run this in test for a while to see how it goes…

Hi Jubilex,

Can you explain what you did in bit more detail? I tried to do what you did. But config.mk keeps changing back and so I’m not able to remove the conflicting definition.

Thanks in advance,


It’s a bit involved… you end up having to repackage the SRPMS in MLNX_OFED_SRC so that you can run mlnx_add_kernel_support.sh. I cannot remember all the steps.

Here is a tarball of the modified MLNX_OFED_LINUX with added support for 2.6.18-371.1.2.el5. Hope this helps.

Thanks so much for doing this work. With a slight addition to mlnx_add_kernel_support, you distribution works for CentOS (and, I assume RH) 5.11.
