Description rz-rpi03 2025-02-24 22:27:09 UTC 
Hello,

after updating CURRENT to main-n275634 loading the pf kernel modude failes now
with the error messages:

  link_elf_obj: symbol _libmd_SHA512_Init undefined
  linker_load_file: /boot/kernel/pf.ko - unsupported file type

SHA512 was introuduced to pf.c by commit
https://cgit.freebsd.org/src/commit/sys/netpfil/pf/pf.c?id=9d5c83a0b84caab2fbc4be22a7008b280aaedc80

Regards, Ralf

Do you have a non-default kernel configuration? The module loads just fine on my machines and in the CI builds, so there's a missing factor here.
Comment 2 rz-rpi03 2025-02-25 17:10:50 UTC 
(In reply to Kristof Provost from comment #1)
Exactly. It is based on the standard amd64 MINIMAL-NODEBUG configuration.
Added ROUTE_MPATH, FIB_ALGO, scbus, da, virtio_scsi and
switches off XEN plus COMPAT_FREEBSD*.

So everything extra needed has to be loaded as a kernel module.

Please attach your kernel config so I can attempt to reproduce this.

Used almost minimal kernel configuration.

Kernel configuration as explained.

    pf: list dependecy on crypto.ko

    Since 9d5c83a0b84c pf depends on the crypto module (for SHA512_*).
    Explicitly list this dependency.
