There is only one functional change here - we don't allow SIOCSVH (or netlink request) to change sc->sc_version. I'm convinced that allowing such a change doesn't brings any practical value, but creates enless minefields in front of both developers and end users (sysadmins). If you want to switch from VRRP to CARP or vice versa, you'd need to recreate the VHID. Oh, one tiny funtional change: carp_ioctl_set() won't modify any fields if it returns EINVAL. Previously you could provide valid advbase with invalid advskew - that used to modify advbase and return EINVAL. All other changes is a sweep around not ever using CARP fields when we are in VRRP mode and vice versa. Also adding assertions on sc_version where necessary. Do not send VRRP vars in CARP mode via NetLink and vice versa. However in compat ioctl SIOCGVH for VRRP mode the CARP fields would be zeroes. This allows to declare softc as union and thus prevent any future logic deterioration wrt to mixing VRRP and CARP. Reviewed by: kp Differential Revision: https://reviews.freebsd.org/D45039 |

FreeBSD Kernel Source:
This directory contains the source files and build glue that make up the FreeBSD kernel and its modules, including both original and contributed software.
Kernel configuration files are located in the conf/
subdirectory of each
architecture. GENERIC
is the configuration used in release builds. NOTES
contains documentation of all possible entries. LINT
is a compile-only
configuration used to maximize build coverage and detect regressions.
Documentation:
Source code documentation is maintained in a set of man pages, under section 9.
These pages are located in share/man/man9
, from the
top-level of the src tree. Consult intro(9)
for an overview of existing pages.
Some additional high-level documentation of the kernel is maintained in the Architecture Handbook.
