* bsdinstall: draw attention to new network config optionsMike Karels2024-03-271-1/+1
| | | | | | | | | | | | The network configuration options have changed in bsdinstall, with an Auto option to proceed directly to DHCP and IPv6 autoconfig (which is the default) as well as Manual (the old mode). For users like me that were used to hitting return automatically to select an interface, but want manual configuration, attempt to call out the difference: Change the menu caption to say "Please select a network interface and configuration mode:" and not just an interface.

* diff: Integrate libdiff from OpenBSD GoT.Dag-Erling Smørgrav2024-03-2713-22/+502
| | | | | | | | | | | | | | | | | | | | | | | This adds support for two new diff algorithms, Myers diff and Patience diff. These algorithms perform a different form of search compared to the classic Stone algorithm and support escapes when worst case scenarios are encountered. Add the -A flag to allow selection of the algorithm, but default to using the new Myers diff implementation. The libdiff implementation currently only supports a subset of input and output options supported by diff. When these options are used, but the algorithm is not selected, automatically fallback to the classic Stone algorithm until support for these modes can be added.

| | | | | | | | | | | | | | | | | | | | | | | | | | | netmap_generic keeps a pool of mbufs for handling transfers, these mbufs have an external buffer attached to them. If some cases other parts of the network stack can chain these mbufs, when this happens the normal pool destructor function can end up free'ing the pool mbufs twice: - A first time if a pool mbuf has been chained with another mbuf when its chain is freed - A second time when its entry in the pool is freed Additionally, if other parts of the stack demote a pool mbuf its interface reference will be cleared. In this case we deference a NULL pointer when trying to free the mbuf through the destructor. Store a reference to the adapter in ext_arg1 with the destructor callback so we can find the correct adapter when free'ing a pool mbuf. This change enables using netmap with epair interfaces.

* kern linker: Do not touch userrefs of the kernel fileZhenlei Huang2024-03-261-0/+3
| | | | | | | | | | | | | | | A nonzero `userrefs` of a linker file indicates that the file, either loaded from kldload(2) or preloaded, can be unloaded via kldunload(2). As for the kernel file, it can be unloaded by the loader but should not be after initialization.
