Bug ID: 1794886 Summary: modprobe by alias broken Product: Fedora Version: 31 Status: NEW Component: kmod Assignee: kmod-maint@lists.fedoraproject.org Reporter: doug@uq.edu.au QA Contact: extras-qa@fedoraproject.org CC: jonathan@jonmasters.org, kmod-maint@lists.fedoraproject.org, skozina@redhat.com, ykaliuta@redhat.com Target Milestone: --- Classification: Fedora

Description of problem: `modprobe net-l2tp-type-7` doesn't work, but `modprobe l2tp_ppp` does.

Note that net-l2tp-type-7 is an alias of l2tp_ppp : $ modinfo l2tp_ppp | grep alias alias: net-l2tp-type-7 alias: net-pf-24-proto-1

Version-Release number of selected component (if applicable):

How reproducible: always on Fedora 31, but works fine on Fedora 30.

Steps to Reproduce: 1. Ensure kernel-modules-extra is installed, as it has the l2tp_ppp kernel module.

2. sudo modprobe net-l2tp-type-7

Actual results:

No l2tp_ppp (or for that matter any l2tp) kernel module has been loaded:

$ lsmod | grep l2tp

Expected results:

This is the output on Fedora 30 : $ lsmod | grep l2tp l2tp_ppp 32768 0 l2tp_netlink 28672 1 l2tp_ppp l2tp_core 36864 2 l2tp_ppp,l2tp_netlink pppox 16384 1 l2tp_ppp ip6_udp_tunnel 16384 1 l2tp_core udp_tunnel 16384 1 l2tp_core ppp_generic 49152 2 pppox,l2tp_ppp

If `modprobe l2tp_ppp` is used instead, the lsmod output is the same as Fedora 30.

Additional info: I also tried using Fedora 30 kernels on Fedora 31, but same result, so can probably rule out the kernel and different kernel versions.
