spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch up to that fact and revert to their recommended match of BSD-2-Clause. Discussed with: pfg MFC After: 3 days Sponsored by: Netflix

Define a module version for accept filter modules. Otherwise accept filters compiled into the kernel do not preempt preloaded accept filter modules. Then, the preloaded file registers its accept filter module before the kernel, and the kernel's attempt fails since duplicate accept filter list entries are not permitted. This causes the preloaded file's module to be released, since module_register_init() does a lookup by name, so the preloaded file is unloaded, and the accept filter's callback points to random memory since preload_delete_name() unmaps the file on x86 as of r336505. Add a new ACCEPT_FILTER_DEFINE macro which wraps the accept filter and module definitions, and ensures that a module version is defined.

sys: general adoption of SPDX licensing ID tags. 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.

In preparation of merging projects/sendfile, transform bare access to sb_cc member of struct sockbuf to a couple of inline functions: sbavail() and sbused() Right now they are equal, but once notion of "not ready socket buffer data", will be checked in, they are going to be different.

Rework socket upcalls to close some races with setup/teardown of upcalls. - Each socket upcall is now invoked with the appropriate socket buffer locked. It is not permissible to call soisconnected() with this lock held; however, so socket upcalls now return an integer value. The two possible values are SU_OK and SU_ISCONNECTED. If an upcall returns SU_ISCONNECTED, then the soisconnected() will be invoked on the socket after the socket buffer lock is dropped. - A new API is provided for setting and clearing socket upcalls. The API consists of soupcall_set() and soupcall_clear(). - To simplify locking, each socket buffer now has a separate upcall. - When a socket upcall returns SU_ISCONNECTED, the upcall is cleared from the receive socket buffer automatically. Note that a SO_SND upcall should never return SU_ISCONNECTED. - All this means that accept filters should now return SU_ISCONNECTED instead of calling soisconnected() directly. They also no longer need to explicitly clear the upcall on the new socket. - The HTTP accept filter still uses soupcall_set() to manage its internal state machine, but other accept filters no longer have any explicit knowlege of socket upcall internals aside from their return value. - The various RPC client upcalls currently drop the socket buffer lock while invoking soreceive() as a temporary band-aid. The plan for the future is to add a new flag to allow soreceive() to be called with the socket buffer locked. - The AIO callback for socket I/O is now also invoked with the socket buffer locked. Previously sowakeup() would drop the socket buffer lock only to call aio_swake() which immediately re-acquired the socket buffer lock for the duration of the function call. Discussed with: rwatson, rmacklem

Correct the sense of a test so that this filter always waits for the full request to arrive. Previously it would end up returning as soon as the request length stored in the first two bytes had arrived. Reviewed by: dwmalone MFC after: 1 week

Add an accept filter for TCP based DNS requests. It waits until the whole first request is present before returning from accept.
