++ Application changes: ++ Application changes:
* Replaced struct ip_addr by typedef ip_addr_t. * Replaced struct ip_addr by typedef ip_addr_t (struct ip_addr is kept for
compatibility to old applications, but will be removed in the future).
* Raw API: Changed the semantics of tcp_close() (since it was rather a
shutdown before): Now the application does *NOT* get any calls to the
recv callback after calling tcp_close() - this means that it also does
not get the NULL-pbuf which tells it the remote side has closed, too!
* Raw API: When calling tcp_abort() from a raw API TCP callback function,
make sure you return ERR_ABRT to prevent accessing unallocated memory.
(ERR_ABRT now means the applicaiton has called tcp_abort!)
* Renamed mem_realloc() to mem_trim() to prevent confusion with realloc() * Renamed mem_realloc() to mem_trim() to prevent confusion with realloc()
* Netconn API: Changed netconn_receive() and netconn_accept() to return +++ Raw API:
* Changed the semantics of tcp_close() (since it was rather a
shutdown before): Now the application does *NOT* get any calls to the recv
callback (aside from NULL/closed) after calling tcp_close() - this means
that it also does not get the NULL-pbuf which tells it the remote side has
closed, too!
* When calling tcp_abort() from a raw API TCP callback function,
make sure you return ERR_ABRT to prevent accessing unallocated memory.
(ERR_ABRT now means the applicaiton has called tcp_abort!)
+++ Netconn API:
* Changed netconn_receive() and netconn_accept() to return
err_t, not a pointer to new data/netconn. err_t, not a pointer to new data/netconn.
* Socket API / LWIP_SO_RCVTIMEO: when accept() or recv() time out, they +++ Socket API:
* LWIP_SO_RCVTIMEO: when accept() or recv() time out, they
now set errno to EWOULDBLOCK/EAGAIN, not ETIMEDOUT. now set errno to EWOULDBLOCK/EAGAIN, not ETIMEDOUT.
* Added a minimal version of posix fctl() to have a
standardised way to set O_NONBLOCK for nonblocking sockets.
+++ all APIs:
* correctly implemented SO(F)_REUSEADDR
++ Port changes ++ Port changes
* Added 4 new files: def.c, timers.c, timers.h, tcp_impl.h +++ new files:
* Added 4 new files: def.c, timers.c, timers.h, tcp_impl.h:
* Moved stack-internal parts of tcp.h to tcp_impl.h, tcp.h now only contains * Moved stack-internal parts of tcp.h to tcp_impl.h, tcp.h now only contains
the actual application programmer's API the actual application programmer's API
* Separated timer implementation from sys.h/.c, moved to timers.h/.c * Separated timer implementation from sys.h/.c, moved to timers.h/.c;
Added timer implementation for NO_SYS==1, set NO_SYS_NO_TIMERS==1 if you
still want to use your own timer implementation for NO_SYS==0 (as before).
* Converted and semaphore functions to take pointers to sys_mbox_t/sys_sem_t; +++ sys layer:
* Converted mbox- and semaphore-functions to take pointers to sys_mbox_t/
sys_sem_t;
* Converted sys_mbox_new/sys_sem_new to take pointers and return err_t; * Converted sys_mbox_new/sys_sem_new to take pointers and return err_t;
* Added Mutex concept in sys_arch (define LWIP_COMPAT_MUTEX to let sys.h use * Added Mutex concept in sys_arch (define LWIP_COMPAT_MUTEX to let sys.h use
binary semaphores instead of mutexes - as before) binary semaphores instead of mutexes - as before)
* Integrated loopif into netif.c - loopif does not have to be created by the +++ new options:
port any more, just define LWIP_HAVE_LOOPIF to 1.
* Don't waste memory when chaining segments, added option TCP_OVERSIZE to
prevent creating many small pbufs when calling tcp_write with many small
blocks of data. Instead, pbufs are allocated larger than needed and the
space is used for later calls to tcp_write.
* Added LWIP_NETIF_TX_SINGLE_PBUF to always copy to try to create single pbufs
in tcp_write/udp_send.
* Added an additional option LWIP_ETHERNET to support ethernet without ARP
(necessary for pure PPPoE)
* Add MEMP_SEPARATE_POOLS to place memory pools in separate arrays. This may
be used to place these pools into user-defined memory by using external
declaration.
* Added TCP_SNDQUEUELOWAT corresponding to TCP_SNDLOWAT
+++ new pools:
* Netdb uses a memp pool for allocating memory when getaddrinfo() is called, * Netdb uses a memp pool for allocating memory when getaddrinfo() is called,
so MEMP_NUM_NETDB has to be set accordingly. so MEMP_NUM_NETDB has to be set accordingly.
* Snmp-agent uses memp pools instead of the heap, so MEMP_NUM_SNMP_* have to * DNS_LOCAL_HOSTLIST_IS_DYNAMIC uses a memp pool instead of the heap, so

* Snmp-agent uses a memp pools instead of the heap, so MEMP_NUM_SNMP_* have
to be set accordingly.
* PPPoE uses a MEMP pool instead of the heap, so MEMP_NUM_PPPOE_INTERFACES
has to be set accordingly
* Integrated loopif into netif.c - loopif does not have to be created by the
port any more, just define LWIP_HAVE_LOOPIF to 1.
* Added define LWIP_RAND() for lwip-wide randomization (needs to be defined * Added define LWIP_RAND() for lwip-wide randomization (needs to be defined
in cc.h, e.g. used by igmp) in cc.h, e.g. used by igmp)
* Added printf-formatter X8_F to printf u8_t as hex * Added printf-formatter X8_F to printf u8_t as hex
* The heap now may be moved to user-defined memory by defining
LWIP_RAM_HEAP_POINTER as a void pointer to that memory's address
* added autoip_set_struct() and dhcp_set_struct() to let autoip and dhcp work
with user-allocated structs instead of calling mem_malloc
* Added const char* name to mem- and memp-stats for easier debugging.
* Calculate the TCP/UDP checksum while copying to only fetch data once:
Define LWIP_CHKSUM_COPY to a memcpy-like function that returns the checksum
* Added SO_REUSE_RXTOALL to pass received UDP broadcast/multicast packets to
more than one pcb.
++ Major bugfixes/improvements
* Implemented tcp_shutdown() to only shut down one end of a connection
* Implemented shutdown() at socket- and netconn-level
* Added errorset support to select() + improved select speed overhead
* Merged pppd to v2.3.11 (including some backported bugfixes from 2.4.x)
* Added timer implementation for NO_SYS==1 (may be disabled with NO_SYS_NO_TIMERS==1
* Use macros defined in ip_addr.h to work with IP addresses
* Implemented many nonblocking socket/netconn functions
* Fixed ARP input processing: only add a new entry if a request was directed as us
* mem_realloc() to mem_trim() to prevent confusion with realloc()
* Some improvements for AutoIP (don't route/forward link-local addresses, don't break
existing connections when assigning a routable address)
* Correctly handle remote side overrunning our rcv_wnd in ooseq case
* Removed packing from ip_addr_t, the packed version is now only used in protocol headers
* Corrected PBUF_POOL_BUFSIZE for ports where ETH_PAD_SIZE > 0
* Added support for static ARP table entries
