The ebtables code relies on the `-nostartfiles` linker argument to execute the extension modules' `_init()` functions automatically which is not working reliably across all supported targets and gcc versions. Running an ebtables executable linked this way just crashes with a segmentation fault at runtime on program startup, e.g. on ARM architectures. In order to fix the issue ... - remove the use of the -nostartfiles linker flag - rename the init procedures to a generic name without implicit semantics - explicitely annotate those init procedures as constructors The patch has been taken from the Alpine Linux distribution at http://git.alpinelinux.org/cgit/aports/tree/main/ebtables/fix-extension-init.patch Signed-off-by: Jo-Philipp Wich <jo@mein.io>

The ebtables program is a filtering tool for a bridging firewall. The
|
|
filtering is focussed on the Link Layer Ethernet frame fields. Apart
|
|
from filtering, it also gives the ability to alter the Ethernet MAC
|
|
addresses and implement a brouter.
