NS 2.70

Bugs

ID	Summary
NS-263	HttpClient: Connection to HTTPS web server through Proxy fails
NS-262	Improve SlNetIf_loadSecObj's parameter validation
NS-254	SlNetSock should use POSIX sem's rather than pthread_mutexes
NS-249	SlNetSock_close() leaks memory if underlying interface's close() fails
NS-248	SlNetUtil_getHostByName() should lookup IP addr names rather than delegate to lower stacks
NS-247	SlNetUtil_inetPton does not return 0 for invalid inputs or -1 for invalid family
NS-246	HTTP Server error response buffer is too small to fit its longest message
NS-244	Failed TLS handshake in HTTP Server can leak sockets
NS-227	HTTPClient gets stuck parsing headers when header data size == 256 bytes
NS-174	HTTPClient_connect() should allow users to specify acceptable security errors
NS-156	Missing typedef for struct linger in BSD layer
NS-103	SlNetIf_query() should find interfaces that are ‘Connected’, not ‘Not Disconnected’

Enhancements

ID	Summary
NS-261	SlNetIf_loadSecObj should enable unloading a secure object
NS-257	Add M33/M33F (TICLANG) library support
NS-250	Provide SysConfig support for generating SlNet init code
NS-168	HTTPClient should enable CC3xxx option to disable certificate store

NS 2.60

Bugs

ID	Summary
NS-209	HTTPClient documentation missing define explanations
NS-188	MQTTClient documentation missing functions

Enhancements

ID	Summary
NS-224	Move JSON library from Network Services to TI Utilties
NS-222	Explicitly document that NS requires an RTOS
NS-217	The HTTP Server shall support secure connections (HTTPS)

Compatibility Notes

• To address NS-224, the JSON builder/parser that was previously managed as part of the Network Services Component is now managed in the TI Utilities Component. You will now need to look there for documentation.

NS 2.50

Bugs

ID	Summary
NS-178	Internal global variables should be static to limit scope
NS-177	SlNetIf_setPriority() may corrupt interface list
NS-175	API Reference Guide documentation issues
NS-93	timeval definition conflict between POSIX <sys/time.h> and NS <sys/select.h>

Enhancements

ID	Summary
NS-184	Add C66 (ccs) and C647x (ccs) libraries
NS-183	Add Arm9 (ccs) libraries
NS-10	Add HTTP Server

Compatibility Notes

• To address NS-93, the SlNetSock headers introduced a dependency on the POSIX header <sys/time.h>. This avoids a previous conflict between time-related structures defined by both POSIX and SlNetSock - now they are all defined by POSIX. This change is often source compatible, but if you didn’t previously have the POSIX header directory on your include path, it will need to be added.

NS 2.40

Bugs

ID	Summary
NS-172	Introduce several SLNETSOCK TCP socket options
NS-167	HTTPClient reconnects fail for secure connections
NS-166	Add support for ENETDOWN in ErrnoUtil_set
NS-159	TCP_NODELAY should be defined in netinet/tcp.h
NS-157	SlNetSock_create() does not use the highest priority interface
NS-155	Memory leak in HTTPClient_connect's call to startSecureMode
NS-129	gethostbyname is not returning correct data structure
NS-124	Add support for SLNETSOCK_OPSOCK_BROADCAST socket option

Enhancements

ID	Summary
NS-107	Add A8F (gcc), A9F (gcc), A15F (gcc), A53F (gcc) and R5F (ccs) libraries

Compatibility Notes

• To address NS-129, gethostbyname() now correctly complies with the POSIX spec. Users should not expect the previous, errant implementation.
• To address NS-159, TCP_NODELAY is now correctly declared in netinet/tcp.h. Previously it was errantly declared in sys/socket.h. Users of this definition should update their code to use the new, now-POSIX-compliant header.h

NS 2.30

Bugs

ID	Summary
NS-136	accept() should return ENFILE when no more sockets available
NS-135	SlNetUtils_getHostByName() can fail when searching multiple interfaces
NS-133	Internal symbol to HTTPClient.c should be made static
NS-130	inet_ntop() should expect/accept addresses in network byte order
NS-128	Enable HTTPClient to send custom headers in HTTP requests
NS-126	Memory Leak in the JSON lib
NS-125	Closing secure sockets causes a memory leak
NS-118	getaddrinfo: IPv6 DNS resolution failure eclipses prior IPv4 DNS success
NS-104	Add getaddrinfo() and freeaddrinfo()
NS-94	getaddrinfo() doesn't support family type AF_INET6

Enhancements

ID	Summary
NS-78	Add gai_strerror()

NS 2.20

Bugs

ID	Summary
NS-111	SlNetUtil_getHostByName() ipaddr arg should be single pointer, not double pointer
NS-101	SlNetSock_secAttribSet and SlNetSock_startSec documentation needs improvement
NS-99	ADDRSTRLEN definitions (both POSIX and SLNETSOCK) are wrong
NS-98	SlNetIf_getIDByName() compares pointers when it should be comparing strings
NS-97	SlNetUtil_inetNtop() fails for IPv6 addrs
NS-96	SlNetUtil_inetNtop() fails for IPv4 addr segments equal to zero
NS-88	move NS header #includes outside of __cplusplus guards

NS-77	inet_pton() is not thread safe

Enhancements

ID	Summary
NS-86	Add MSG_WAITALL
NS-82	SlNetUtil_getHostByName() should return interface id
NS-81	Add SNTP client

NS 2.00

Bugs

ID	Summary
NS-47	Add debug/release libraries support to NS product

Enhancements

ID	Summary
NS-74	Introduce SlNetSock abstraction over network and TLS stacks

Compatibility Notes

The Network Services Modules have been “rebooted” to improve alignment across TI’s various networking stacks. As a result, NS 2.x is completely incompatible with NS 1.x releases, and there are gaps between the features available in NS 1.x and 2.x.
