Modified files:
sys/kern kern_module.c
sys/sys module.h
Log:
Add an automatic kernel module version dependency to prevent loading
modules using invalid ABI versions (e.g. a 7.x module with an 8.x kernel)
for a given kernel:
- Add a 'kernel' module version whose value is __FreeBSD_version.
- Add a version dependency on 'kernel' in every module that has an
acceptable version range of __FreeBSD_version up to the end of the
branch __FreeBSD_version is part of. E.g. a module compiled on 701000
would work on kernels with versions between 701000 and 799999 inclusive.
