I've fixed this issue upstream by instead wrapping `make modules` with `bwrap` that overlays the needed files in place, and tested to work on Linux 6.13 in experimental. (still hacky, but less prone to changes like this) I am planning on the next minor upstream release and respective Debian packaging, but for 0.6.3+ds-1 the attached patch could be used (in addition to adding bubblewrap to mimic-dkms' Depends). Bubblewrap is a ~100 KB package so it won't be too much bloat.
With the 0.7.* package I don't see any errors with the current kernels that have the btf bits in their linux-headers-* package, but with the older ones which didn't: DKMS (dkms-3.1.5) make.log for mimic/0.7.0+ds for kernel 6.12.15-amd64 (x86_64) Tue Mar 11 13:05:02 UTC 2025 Building module(s) # command: make -j14 KERNELRELEASE=6.12.15-amd64 KERNEL_UNAME=6.12.15-amd64 CHECKSUM_HACK=kfunc cp -rL /lib/modules/6.12.15-amd64/build overlay PATH="$PATH:/usr/lib/mimic:/var/lib/dkms/mimic/0.7.0+ds/build/../out:/var/lib/dkms/mimic/0.7.0+ds/build/../tools" vmlinux-to-btf >overlay/vmlinux Found vmlinuz at /boot/vmlinuz-6.12.15-amd64 Trying extract-vmlinux (only works on bzImage and with relevant decompressor installed)... tail: error writing 'standard output': Broken pipe install -Dm755 /usr/lib/mimic/resolve_btfids overlay/tools/bpf/resolve_btfids/resolve_btfids bwrap --dev-bind / / --ro-bind overlay /usr/src/linux-headers-6.12.15-amd64 make -C /lib/modules/6.12.15-amd64/build M=/var/lib/dkms/mimic/0.7.0+ds/build modules bwrap: pivot_root: Invalid argument make: *** [Makefile:73: build] Error 1 # exit code: 2 # elapsed time: 00:00:02 ---------------------------------------------------------------- Andreas
