Description Ross Burton 2024-05-01 13:32:54 UTC 
Right now the reproducer is poky scarthgap, meta-arm master (or scarthgap if it exists when you read this), MACHINE=sbsa-ref, linux-yocto-dev:

|   MODPOST vmlinux.symvers
| ERROR: modpost: vmlinux: local symbol 'security_path_rmdir' was exported

Comment 1 Ross Burton 2024-05-01 15:24:42 UTC 
Interestingly sbsa-ref is a qemu-based machine using the defconfig kernel, but if I add this then it doesn't fail:

KBUILD_DEFCONFIG:qemuarm46 = "defconfig"
KCONFIG_MODE:qemuarm46 = "--alldefconfig"


Why that is remains a mystery.
Comment 2 Randy MacLeod 2024-10-17 19:04:14 UTC 
Bulk move of medium importance bugs from 5.1 to 5.2 on behalf of Bruce.
Comment 3 Ross Burton 2026-03-05 16:17:18 UTC 
I can still replicate this with scarthgap and linux-yocto-dev.
Comment 4 Richard Purdie 2026-07-23 15:12:33 UTC 
What is qemuarm46?
Comment 5 Randy MacLeod 2026-07-23 15:13:09 UTC 
Ross to retest with a 64 bit system, rather than the mystery 46 bit system.
Comment 6 Ross Burton 2026-07-23 16:06:27 UTC 
Our CI still replicates this with sbsa-ref/alldefconfig/linux-yocto-dev on scarthgap, but not wrynose or master.

Testing qemuarm64 now...
Comment 7 Bruce Ashfield 2026-10-27 22:16:36 UTC 
This only reproduces with linux-yocto-dev on scarthgap; Ross confirmed it does not reproduce on wrynose or master. linux-yocto-dev tracks master and isn't a supported combination on the scarthgap release branch, so I'm closing this out. If it shows up with linux-yocto-dev on master, please reopen.
