net: ipv6: unexport __init-annotated seg6_hmac_net_init()
commit 53ad46169fe2996fe1b623ba6c9c4fa33847876f upstream.
As of commit 5801f064e351 ("net: ipv6: unexport __init-annotated seg6_hmac_init()"),
EXPORT_SYMBOL and __init is a bad combination because the .init.text
section is freed up after the initialization. Hence, modules cannot
use symbols annotated __init. The access to a freed symbol may end up
with kernel panic.
This remove the EXPORT_SYMBOL to fix modpost warning:
WARNING: modpost: vmlinux.o(___ksymtab+seg6_hmac_net_init+0x0): Section mismatch in reference from the variable __ksymtab_seg6_hmac_net_init to the function .init.text:seg6_hmac_net_init()
The symbol seg6_hmac_net_init is exported and annotated __init
Fix this by removing the __init annotation of seg6_hmac_net_init or drop the export.
