To reproduce, set debug.link_elf_leak_locals=3D0 debug.link_elf_obj_leak_locals=3D0 then # kldload tcp_bbr.ko TCP HPTS started 1 ((unbounded)) swi interrupt threads link_elf_obj: symbol tcp_hptsi_pace undefined linker_load_file: /boot/kernel/tcp_bbr.ko - unsupported file type kldload: an error occurred while loading module tcp_bbr.ko. Please check dmesg(8) for more details. # kldload tcp_rack.ko TCP HPTS started 1 ((unbounded)) swi interrupt threads link_elf_obj: symbol tcp_hptsi_pace undefined linker_load_file: /boot/kernel/tcp_rack.ko - unsupported file type kldload: an error occurred while loading module tcp_rack.ko. Please check dmesg(8) for more details. The dependent module's Makefile (i.e., the one containing tcp_hptsi_pace) should have an EXPORT_SYMS=3D line that lists all of the symbols to be intentionally exported. Another option is to just set EXPORT_SYMS=3DYES. An explicit export list is preferred over EXPORT_SYMS=3DYES, unless we explicitly want all symbols exp= orted. --=20 You are receiving this mail because: You are the assignee for the bug.=
