Hello , I’m new to netmap where I’m trying to insert netmap.ko module after compiling my kernel and I’m shown with the following error: netmap: Unknown symbol split_page (err 0) Here are the steps and different methods I followed: I. Compile Kernel 3.2.0 1. My Ubuntu 12.04 machine has a kernel version 3.2.0-90-generic, so i got the linux source by: sudo apt-get source linux-source-3.2.0 2. Then i work on trying to compile the kernel a. sudo make menuconfig — Keep default config b. sudo sed -i s/CONFIG_RTS5139=m/CONFIG_RTS5139=n/ .config - to avoid compilation errors c. sudo make clean d. sudo make -j10 e. sudo make bzImage f. sudo make modules g.sudo make modules_install h. sudo make install i. sudo update-grub2 j. sudo reboot. 2 b. On checking kernel version using name -r , this is the kernel version - 3.2.79 3. Then i download the netmap-master branch from git and upload it to my machine , cannot use git clone as it doesn’t support external connections. 4.Unzipping the bundle and switch to LINUX folder to run ./configure 5. Here i received errors where netmap-master/LINUX/drivers/ext-patch couldn’t be downloaded due to failure to connect. 6. I downloaded these drivers and placed them in that path. 7. I received a warning telling cannot find complete kernel sources, which i referenced later as ./configure —kernel-sources = /lib/modules/linux-source-(uname -r)/build 8. Then after clearing all warning and errors, the generated netmap.ko file I try to insert , which gives me the error netmap: Unknown symbol split_page (err 0) II. Avoid kernel compliation 1. Then i download the netmap-master branch from git and upload it to my machine , cannot use git clone as it doesn’t support external connections. 2.Unzipping the bundle and switch to LINUX folder to run ./configure 3. Here i received errors where netmap-master/LINUX/drivers/ext-patch couldn’t be downloaded due to failure to connect. 4. I downloaded these drivers and placed them in that path. 5. I received a warning telling cannot find complete kernel sources, which i referenced later as ./configure —kernel-sources = /lib/modules/linux-source-(uname -r)/build 6. Then after clearing all warning and errors, the generated netmap.ko file I try to insert , which gives me the error netmap: Unknown symbol split_page (err 0) III. Tried switching to FreeBSD Cannot download the FreeBSD 10.2 image due to security reasons mentioned in git / wget. I’m totally stuck for the past 2 weeks and would appreciate help on this. Thanks H
