* ifconfig: remove (most of) the usages of global 'struct ifreq ifr'.Alexander V. Chernikov2023-06-161-17/+18
| | | | | | | | | | | It is hard to reason about the contents of 'ifr' at any given time as nearly every function sets random fields or pointers in this structure. Use local on-stack clean 'struct ifreq' for each function instead. Reviewed by: kp Differential Revision: https://reviews.freebsd.org/D40534 MFC after: 2 weeks

* pf: make contents of struct pfsync_state configurableKajetan Staszkiewicz2023-05-301-1/+27
| | | | | | | | | | | | | | | | | | Make struct pfsync_state contents configurable by sending out new versions of the structure in separate subheader actions. Both old and new version of struct pfsync_state can be understood, so replication of states from a system running an older kernel is possible. The version being sent out is configured using ifconfig pfsync0 … version XXXX. The version is an user-friendly string - 1301 stands for FreeBSD 13.1 (I have checked synchronization against a host running 13.1), 1400 stands for 14.0. A host running an older kernel will just ignore the messages and count them as "packets discarded for bad action".

* ifconfig: introduce `ifconfig_context` to store current global state.Alexander V. Chernikov2023-05-241-41/+27
| | | | | | | | | | | | | | | | | The structure consists of all current context - arguments, open sockets, current family and so on. Pass this structure as a first argument to most of the af_ menthods. This allows to propagate and update shared data without using global variables. The diff is pretty large, but de-facto mechanical. All changes except the structure setup in ifconfig[_netlink].c are one-line mechanical changes. Reviewed by: kp Differential Revision: https://reviews.freebsd.org/D40239 MFC after: 2 weeks

* pfsync: prepare code to accommodate AF_INET6 familyLuiz Amaral2022-11-091-77/+245
| | | | | | | | | | | | Work is ongoing to add support for pfsync over IPv6. This required some changes to allow for differentiating between the two families in a more generic way. This patch converts the relevant ioctls to using nvlists, making future extensions (such as supporting IPv6 addresses) easier.

* pfsync: fix incorrect enabling of defer modeKristof Provost2021-12-061-1/+1
| | | | | | | | | | | | | When we exposed the PFSYNCF_OK flag to userspace in 5f5bf88949d we unintentionally caused defer mode to always be enabled. The ioctl check only looked for nonzero, not for the PFSYNCF_DEFER flag. Fix this check and ensure ifconfig sets the flag.

* various: general adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-271-1/+3
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. No functional change intended.
