Title:
dkms script is missing function find_module
Status in DKMS:
Fix Released
Status in dkms package in Ubuntu:
Confirmed
Status in dkms source package in Bionic:
Fix Released
Bug description:
update for SRU process:
[Impact]
1. dkms script is missing function find_module
2. priority of OBSOLETE_BY should higher than "force". #89
https://github.com/dell/dkms/issues/89
[Test case]
install the dkms which already patched (also can be found in my ppa[1])
1. install a dkms which for a kernel module system already installed.
e.g. ath10k of my testing ppa : [1]
1.1. the dkms can be installed well.
2. install a dkms which has OBSOLETE_BY and FORCE
e.g.ath10k of my testing ppa : [1] (source code in [2])
- the target dkms defined OBSOLETE_BY and FORCE
- user install dkms on a system which installed kernel version less than
OBSOLETE_BY and another kernel higher than OBSOLETE_BY
- the dkms can be installed well.
[Regression potential]
medium as it touched the version sanity. This change correct the code logic
and land one more change from upstream as well.
The logic has been verified by #5 and me.
------------------------------------------------------------------------
Building a kernel module using dkms in Linux Mint 19.1 shows the following
error:
Running module version sanity check.
/usr/sbin/dkms: Zeile 784: find_module: Befehl nicht gefunden
modinfo: ERROR: missing module or filename.
Checking the file the function is indeed missing and another user
confirmed, that it was removed at some point:
https://github.com/linuxmint/linuxmint/issues/142
Possible solution: Readd
find_module()
{
# tree = $1
# module = $2
find "$1" -name "$2$module_uncompressed_suffix" -o -name
"$2$module_suffix" -type f
return $?
}
