From: Frank Kühndel <frank.kuehn...@embedded-brains.de> The following patches extend the TFTP file system to support
* RFC 2347 TFTP Option Extension * RFC 2348 TFTP Blocksize Option * RFC 7440 TFTP Windowsize Option To benefit from improved download and upload speeds, a TFTP server which supports at least the blocksize option must be used. The code is still downward compatible to simple/old servers which implement only RFC 1350. The patches contain an extensive test suite. The original code was in the single file tftpDriver.c where the file system and the network aspects where entangled. The patches split the code into files tftpfs.c for the file system part and tftpDriver.c for the network related part. Since both files are derived from the original tftpDriver.c, it is possible to keep the git history working for both files when committing the patches to the git repository. For example, as described here: https://devblogs.microsoft.com/oldnewthing/20190919-00/?p=102904 Yet, this method requires a merge and the history gets lost when the commits are "rebased". I cannot say whether this would be worth the trouble. TFTP Files ---------- ``cpukit/include/rtems/tftp.h`` This file declares the public constants, structures, and functions of the Trivial File Transfer Protocol (TFTP) file system. ``cpukit/libfs/src/ftpfs/tftpDriver.c`` This source file contains the implementation of a Trivial File Transfer Protocol (TFTP) client library --- the network related part of the code. ``cpukit/libfs/src/ftpfs/tftp_driver.h`` This file declares private functions of the Trivial File Transfer Protocol (TFTP) client library. ``cpukit/libfs/src/ftpfs/tftpfs.c`` This source file contains the implementation of the Trivial File Transfer Protocol (TFTP) filesystem. The code in this file handles the file system operations (such as ``mount()``, ``open()``, ``read()``, ``write()``, ``close()`` etc.). ``spec/build/cpukit/libtftpfs.yml`` This file specifies how the RTEMS WAF build system has to compile, link and install ``libtftpfs``. ``spec/build/testsuites/fstests/grp.yml`` This file specifies how the RTEMS WAF build system has to compile, link and install all filesystem test suites. The TFTP test suite must be mentioned in this file to be build. ``spec/build/testsuites/fstests/tftpfs.yml`` This file specifies how the RTEMS WAF build system has to compile, link and install the TFTP test suite. ``testsuites/fstests/tftpfs/init.c`` This source file contains the test suite with all tests for ``libtftpfs``. The test suite uses functions from files ``tftpfs_interactions.c`` and ``tftpfs_udp_network_fake.c`` as private helpers. ``testsuites/fstests/tftpfs/tftpfs_interactions.h`` This header file provides definitions and declarations of data structures and functions used to implement network interactions of the UDP network fake for ``libtftpfs`` tests. ``testsuites/fstests/tftpfs/tftpfs_interactions.c`` This source file contains the implementation of network interaction functions related to the UDP network fake for ``libtftpfs`` tests. ``testsuites/fstests/tftpfs/tftpfs_udp_network_fake.h`` This header file provides definitions and declarations of data structures and functions used to implement the UDP network fake for ``libtftpfs`` tests. ``testsuites/fstests/tftpfs/tftpfs_udp_network_fake.c`` This source file contains the implementation of UDP network fake functions related to ``libtftpfs`` testing. This code provides fake implementations for functions like ``socket()``, ``bind()``, ``sendto()``, ``recvfrom()``, etc. which would normally be provided by libbsd.
