 Posted: Wed Nov 22, 2017 3:14 pm Post subject: Can't install correct kernel option for docker |
 |
|
I'm trying to get Docker on my machine but I keep on failing 
When I select the kernel options as in here, then I rebuild my kernel using make, then make_modules and finally make install. That all goes well but when I restart my session, I only have one resolution for the screen which isn't my native resolution. I also think I don't have any network configuration anymore.
My only solution then is to use to recompile the kernel .
I'm using the kernel 12.12. Any solution to get docker to work :/? |

You can run genkernel with --menuconfig option for select correct config in kernel
| Code: | | # genkernel --menuconfig all |

Maybe I've been doing an extra step for 20 years or so. I do:
| Code: |
make menuconfig
mount /boot
make && make modules && make modules_install && make install
grub-mkconfig > /boot/grub/grub.cfg
|
And, if I'm doing this on a remote machine, I do it inside of tmux with top running in a nearby pane. Using tmux allows me to disconnect from the session -- voluntarily or accidentally -- and then reconnect later. Locally I do it that way because I'm used to tmux. Pretty much every terminal I use has it running. And that way if I get happy with the mouse and close the wrong terminal I still have my compile working. |

Yes it was | Code: | | make modules_install |
that was indeed a typo  . I'm trying again with genkernel before choosing the options.
I'll try the other options if that doesn't work. Thanks a lot for you help, keeping y'all updated
_____
EDIT: genkernel with menuconfig lead to the same result as before when I sellected what was needed for docker . I have an unknown display and only 640x480 is available
____
EDIT2: configuring grub2 to after didn't solve the problem either |

Actually I have a couple extra things I do to simplify configuration. People have commented that what I do is convoluted, but it works well for me.
My kernel sources, of course, go to /usr/src/ by default. As usual, you get multiple kernel sources after awhile.
| Code: |
root@spidermonkey /usr/src
# ll
total 40K
drwxr-xr-x 7 root root 4.0K Nov 6 14:49 .
drwxr-xr-x 12 root root 4.0K Aug 4 2015 ..
-rw-r--r-- 1 root root 0 Jul 30 2015 .keep
lrwxrwxrwx 1 root root 27 Nov 6 14:45 linux -> /usr/src/linux-4.12.12-gentoo
drwxr-xr-x 25 root root 4.0K Nov 6 14:16 linux-4.12.12-gentoo
drwxr-xr-x 22 root root 4.0K Nov 4 18:38 linux-4.12.12-g-k1
drwxr-xr-x 22 root root 4.0K Nov 6 14:16 linux-4.12.12-g-k2
drwxr-xr-x 3 root root 4.0K Nov 6 14:54 linux-4.12.12-g-k3
drwx------ 2 root root 16K Oct 1 2015 lost+found
lrwxrwxrwx 1 root root 20 Sep 14 13:04 master -> linux-4.12.12-gentoo
lrwxrwxrwx 1 root root 27 Nov 6 14:45 next -> /usr/src/linux-4.12.12-g-k3
lrwxrwxrwx 1 root root 27 Nov 4 18:40 previous -> /usr/src/linux-4.12.12-g-k2

The 'linux' symbolic link is the customary purpose.
The 'master' symbolic link points to the downloaded source I intend to use for the next build. Usually the same as 'linux'
The 'next' symbolic link points to the working build directory for the next kernel to be compiled.
The 'previous' symbolic link points to the one I used for the most recent built kernel.
I have a script called "kernel-setup" which is here:
| Code: |
#!/bin/bash
if [[ $# != 1 ]];then
echo "Usage: kernel-setup k2"
exit 1
fi
MASTER=$(readlink -e "/usr/src/master")
echo "Base kernel directory is $MASTER"
LBSD=${MASTER/gentoo/g}
echo $LBSD
SUFFIX="$1"
NKSD="$LBSD-$SUFFIX"
# Remove previous
NEXT='/usr/src/next'
PREVIOUS='/usr/src/previous'
if [ -e "$NEXT" ];then
echo "$NEXT exists"
if [ -e "$PREVIOUS" ];then
echo "$PREVIOUS exists"
if [ -L "$PREVIOUS" ];then
echo "Removing $PREVIOUS link"
rm -f $PREVIOUS
else
echo "$PREVIOUS is not a symbolic link!"
exit 1
fi
fi
if [ -L "$NEXT" ];then
echo "Moving $NEXT to $PREVIOUS"
mv $NEXT $PREVIOUS
else
echo "$NEXT is not a symbolic link!"
exit 2
fi
fi
echo "Creating $NKSD"
mkdir $NKSD
$MASTER/scripts/mkmakefile $MASTER $NKSD
cd /usr/src
echo "Marking $NKSD as 'next'"
ln -s $NKSD $NEXT
cd $NKSD
pwd
zcat /proc/config.gz > .config
|
I use kernel suffixes per build, which is the reason for the argument for the above script.
This script uses the 'master' as sources and puts all build products in the new work directory. Builds I make have /usr/src/linux-<version>-g-k# format. I change 'gentoo' to 'g' and then add my suffix that is then configured into the kernel by you.
Now, finally I have a script called kcheck:
| Code: |
#!/bin/bash
echo "Watched:"
cat .config \
| grep -f /root/kernel.grepf \
| grep -vf /root/kernel.grepv
echo "Not Found:"
cat .config \
| grep -Lf /root/kernel.grepf
|
I keep two files in /root/kernel.grepf and /root/kernel.grepv which have kernel options I need to have configured a certain way for the current host.
kernel.grepf looks like this:
| Code: |
CONFIG_64BIT\>
CONFIG_9P_FS\>
CONFIG_9P_FS_POSIX_ACL\>
CONFIG_BRIDGE_EBT_MARK_T\>
CONFIG_BRIDGE_EBT_T_NAT\>
CONFIG_BRIDGE_EBT_VLAN\>
CONFIG_BRIDGE_NF_EBTABLES\>
CONFIG_COMPILE_TEST\>
|
It contains all the kernel options I want to check with my script.
kernel.grepv looks like this:
| Code: |
CONFIG_64BIT=y
CONFIG_9P_FS_POSIX_ACL=y
CONFIG_9P_FS=y
CONFIG_BRIDGE_EBT_MARK_T=y
CONFIG_BRIDGE_EBT_T_NAT=y
CONFIG_BRIDGE_EBT_VLAN=y
CONFIG_BRIDGE_NF_EBTABLES=y
CONFIG_COMPILE_TEST=y
CONFIG_DCA=y
CONFIG_DM_MULTIPATH=y
|
So anything I'm not interested in is filtered out by grepf, and then anything whose value is not what I want is printed as output of grepv.
I cd to /usr/src/next, then run kcheck. The version suffix always prints, so I check that. Otherwise, the only things that print are things which are not configured the way I want. |

| Well I'll look at that tomorrow. And now I'm stuck with that kernel that do not detect my screen and give me the wrong resolution. I'm at a loss with what to do to solve this, and using old config files doesn't seem to work :/ |

For sake of simplicity, make invoked without specifying the target does make bzImage and make modules.
I personally do not do make install, I copy the image over by hand, it has always the same name and I do not have to reconfigure the bootloader afterwards.

I've made too many broken kernels to trust that approach. I keep at least 3 active, two working kernels and one test kernel. Sometimes the thought-to-be-working one has some secret time bomb I didn't think to test before deciding it was good. |

That's been my method for a long time too: `make install` manages the /boot/vmlinuz{,.old} symlinks automatically for me, and every so often I run `for i in config System.map vmlinuz; do cp -L /boot/$i{,.good}; done` manually. I have the default bootloader entry set to vmlinuz.good and use the oneshot feature in lilo/efibootmgr to boot into vmlinuz after an update.
It may sound like overkill, but when you're dealing with headless or remote systems it pays off. |

I never said I have no backup kernel. Actually I always keep a known good one.

Ok so I found the change that ruined my display:
| Code: |
CGROUP_DEBUG n -> y
CGROUP_HUGETLB n -> y
CGROUP_NET_PRIO n -> y
CGROUP_PIDS n -> y
CRYPTO_DH n -> y
ENCRYPTED_KEYS n -> m
IP_NF_NAT n -> m
KEY_DH_OPERATIONS n -> y
NETFILTER_XT_NAT n -> m
NETFILTER_XT_TARGET_NETMAP n -> m
NETFILTER_XT_TARGET_REDIRECT n -> m
NET_L3_MASTER_DEV n -> y
NF_NAT_MASQUERADE_IPV4 n -> m
NF_NAT_REDIRECT n -> m
OVERLAY_FS n -> y
PERSISTENT_KEYRINGS n -> y
+CRYPTO_KPP y
+IPVLAN m
+IPVTAP n
+IP_NF_TARGET_MASQUERADE m
+IP_NF_TARGET_NETMAP m
+IP_NF_TARGET_REDIRECT m
+NET_VRF n
+OVERLAY_FS_REDIRECT_DIR n
|
Not sure what happens here that made my display not being detected anymore :S. But I've inverted all those and now it's all good again  |
