tcp_fill_info(): Change lock assertion on INPCB to locked only

2024-01-05T22:48:34+00:00

This function actually only ever reads from the TCP PCB. Consequently,
also make the pointer to its TCP PCB parameter const.

spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD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.

Initial support for kernel offload of TLS receive.

2020-04-27T23:17:19+00:00

- Add a new TCP_RXTLS_ENABLE socket option to set the encryption and
  authentication algorithms and keys as well as the initial sequence
  number.

- When reading from a socket using KTLS receive, applications must use
  recvmsg().  Each successful call to recvmsg() will return a single
  TLS record.  A new TCP control message, TLS_GET_RECORD, will contain
  the TLS record header of the decrypted record.  The regular message
  buffer passed to recvmsg() will receive the decrypted payload.  This
  is similar to the interface used by Linux's KTLS RX except that
  Linux does not return the full TLS header in the control message.

- Add plumbing to the TOE KTLS interface to request either transmit
  or receive KTLS sessions.

- When a socket is using receive KTLS, redirect reads from
  soreceive_stream() into soreceive_generic().

- Note that this interface is currently only defined for TLS 1.1 and
  1.2, though I believe we will be able to reuse the same interface
  and structures for 1.3.

Convert TOE routing lookups to the new routing KPI.

Add a TOE KTLS mode and a TOE hook for allocating TLS sessions.

2019-10-08T21:34:06+00:00

This adds the glue to allocate TLS sessions and invokes it from
the TLS enable socket option handler.  This also adds some counters
for active TOE sessions.

The TOE KTLS mode is returned by getsockopt(TLSTX_TLS_MODE) when
TOE KTLS is in use on a socket, but cannot be set via setsockopt().

To simplify various checks, a TLS session now includes an explicit
'mode' member set to the value returned by TLSTX_TLS_MODE.  Various
places that used to check 'sw_encrypt' against NULL to determine
software vs ifnet (NIC) TLS now check 'mode' instead.

Extract eventfilter declarations to sys/_eventfilter.h

2019-05-20T00:38:23+00:00

This allows replacing "sys/eventfilter.h" includes with "sys/_eventfilter.h"
in other header files (e.g., sys/{bus,conf,cpu}.h) and reduces header
pollution substantially.

EVENTHANDLER_DECLARE and EVENTHANDLER_LIST_DECLAREs were moved out of .c
files into appropriate headers (e.g., sys/proc.h, powernv/opal.h).

As a side effect of reduced header pollution, many .c files and headers no
longer contain needed definitions.  The remainder of the patch addresses
adding appropriate includes to fix those files.

LOCK_DEBUG and LOCK_FILE_LINE_ARG are moved to sys/_lock.h, as required by
sys/mutex.h since r326106 (but silently protected by header pollution prior
to this change).

No functional change (intended).  Of course, any out of tree modules that
relied on header pollution for sys/eventhandler.h, sys/lock.h, or
sys/mutex.h inclusion need to be fixed.  __FreeBSD_version has been bumped.

sys: general adoption of SPDX licensing ID tags.

2017-11-27T15:23:17+00:00

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.
