The commit cdd30ebb1b9f ("module: Convert symbol namespace to string
|
|
literal") makes the grammar of MODULE_IMPORT_NS and EXPORT_SYMBOL_NS
|
|
different between the stable branches and the mainline. But when
|
|
the commit 955f9ede52b8 ("bpf: Add namespace to BPF internal symbols")
|
|
was backported from mainline, only EXPORT_SYMBOL_NS instances are
|
|
adapted, leaving the MODULE_IMPORT_NS instance with the "new" grammar
|
|
and causing the module fails to build:
|
|
|
|
ERROR: modpost: module bpf_preload uses symbol bpf_link_get_from_fd from namespace BPF_INTERNAL, but does not import it.
|
|
ERROR: modpost: module bpf_preload uses symbol kern_sys_bpf from namespace BPF_INTERNAL, but does not import it.
