This file lists major changes between release versions that require
|
|
ports or applications to be changed. Use it to update a port or an
|
|
application written for an older version of lwIP to correctly work
|
|
with newer versions.

* [Enter new changes just after this line - do not remove this line]
|
|
|
|
(2.0.2)
|
|
|
|
++ Application changes:
|
|
|
|
* slipif: The way to pass serial port number has changed. netif->num is not
|
|
supported any more, netif->state is interpreted as an u8_t port number now
|
|
(it's not a POINTER to an u8_t any more!)
|
|
|
|
(2.0.1)
|
|
|
|
++ Application changes:
|
|
|
|
* UDP does NOT receive multicast traffic from ALL netifs on an UDP PCB bound to a specific
|
|
netif any more. Users need to bind to IP_ADDR_ANY to receive multicast traffic and compare
|
|
ip_current_netif() to the desired netif for every packet.
|
|
See bug #49662 for an explanation.
|
|
|
|
(2.0.0)
|
|
|
|
++ Application changes:
|
|
|
|
* Changed netif "up" flag handling to be an administrative flag (as opposed to the previous meaning of
|
|
"ip4-address-valid", a netif will now not be used for transmission if not up) -> even a DHCP netif
|
|
has to be set "up" before starting the DHCP client
|
|
* Added IPv6 support (dual-stack or IPv4/IPv6 only)
|
|
* Changed ip_addr_t to be a union in dual-stack mode (use ip4_addr_t where referring to IPv4 only).
|
|
* Major rewrite of SNMP (added MIB parser that creates code stubs for custom MIBs);
|
|
supports SNMPv2c (experimental v3 support)
|
|
* Moved some core applications from contrib repository to src/apps (and include/lwip/apps)
|
|
|
|
+++ Raw API:
|
|
* Changed TCP listen backlog: removed tcp_accepted(), added the function pair tcp_backlog_delayed()/
|
|
tcp_backlog_accepted() to explicitly delay backlog handling on a connection pcb
|
|
|
|
+++ Socket API:
|
|
* Added an implementation for posix sendmsg()
|
|
* Added LWIP_FIONREAD_LINUXMODE that makes ioctl/FIONREAD return the size of the next pending datagram
|
|
|
|
++ Port changes
|
|
|
|
+++ new files:
|
|
* MANY new and moved files!
|
|
* Added src/Filelists.mk for use in Makefile projects
|
|
* Continued moving stack-internal parts from abc.h to abc_priv.h in sub-folder "priv"
|
|
to let abc.h only contain the actual application programmer's API
|
|
|
|
+++ sys layer:
|
|
* Made LWIP_TCPIP_CORE_LOCKING==1 the default as it usually performs better than
|
|
the traditional message passing (although with LWIP_COMPAT_MUTEX you are still
|
|
open to priority inversion, so this is not recommended any more)
|
|
* Added LWIP_NETCONN_SEM_PER_THREAD to use one "op_completed" semaphore per thread
|
|
instead of using one per netconn (these semaphores are used even with core locking
|
|
enabled as some longer lasting functions like big writes still need to delay)
|
|
* Added generalized abstraction for itoa(), strnicmp(), stricmp() and strnstr()
|
|
in def.h (to be overridden in cc.h) instead of config
|
|
options for netbiosns, httpd, dns, etc. ...
|
|
* New abstraction for hton* and ntoh* functions in def.h.
|
|
To override them, use the following in cc.h:
|
|
#define lwip_htons(x) <your_htons>
|
|
#define lwip_htonl(x) <your_htonl>
|
|
|
|
+++ new options:
|
|
* TODO
|
|
|
|
+++ new pools:
|
|
* Added LWIP_MEMPOOL_* (declare/init/alloc/free) to declare private memp pools
|
|
that share memp.c code but do not have to be made global via lwippools.h
|
|
* Added pools for IPv6, MPU_COMPATIBLE, dns-api, netif-api, etc.
|
|
* added hook LWIP_HOOK_MEMP_AVAILABLE() to get informed when a memp pool was empty and an item
|
|
is now available
|
|
|
|
* Signature of LWIP_HOOK_VLAN_SET macro was changed
|
|
|
|
* LWIP_DECLARE_MEMORY_ALIGNED() may be used to declare aligned memory buffers (mem/memp)
|
|
or to move buffers to dedicated memory using compiler attributes
|
|
|
|
* Standard C headers are used to define sized types and printf formatters
|
|
(disable by setting LWIP_NO_STDINT_H=1 or LWIP_NO_INTTYPES_H=1 if your compiler
|
|
does not support these)
|
|
|
|
|
|
++ Major bugfixes/improvements
|
|
|
|
* Added IPv6 support (dual-stack or IPv4/IPv6 only)
|
|
* Major rewrite of PPP (incl. keep-up with apache pppd)
|
|
see doc/ppp.txt for an upgrading how-to
|
|
* Major rewrite of SNMP (incl. MIB parser)
|
|
* Fixed timing issues that might have lead to losing a DHCP lease
|
|
* Made rx processing path more robust against crafted errors
|
|
* TCP window scaling support
|
|
* modification of api modules to support FreeRTOS-MPU (don't pass stack-pointers to other threads)
|
|
* made DNS client more robust
|
|
* support PBUF_REF for RX packets
|
|
* LWIP_NETCONN_FULLDUPLEX allows netconn/sockets to be used for reading/writing from separate
|
|
threads each (needs LWIP_NETCONN_SEM_PER_THREAD)
|
|
* Moved and reordered stats (mainly memp/mib2)
|
|
|
|
(1.4.0)
|
|
|
|
++ Application changes:
|
|
|
|
* 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).
|
|
|
|
* Renamed mem_realloc() to mem_trim() to prevent confusion with realloc()
|
|
|
|
+++ 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()
|
|
|
|
* 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.
|
|
|
|
+++ Socket API:
|
|
* LWIP_SO_RCVTIMEO: when accept() or recv() time out, they
|
|
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
|
|
|
|
+++ 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
|
|
the actual application programmer's API
|
|
|
|
* 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).
|
|
|
|
+++ 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;
|
|
|
|
* Added Mutex concept in sys_arch (define LWIP_COMPAT_MUTEX to let sys.h use
|
|
binary semaphores instead of mutexes - as before)
|
|
|
|
+++ new options:
|
|
|
|
* 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,
|
|
so MEMP_NUM_NETDB has to be set accordingly.
|
|
|
|
* DNS_LOCAL_HOSTLIST_IS_DYNAMIC uses a memp pool instead of the heap, so
|
|
MEMP_NUM_LOCALHOSTLIST has to be set accordingly.
|
|
|
|
* 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
|
|
in cc.h, e.g. used by igmp)
|
|
|
|
* 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.
|
|
|
|
* Changed the semantics of ARP_QUEUEING==0: ARP_QUEUEING now cannot be turned
|
|
off any more, if this is set to 0, only one packet (the most recent one) is
|
|
queued (like demanded by RFC 1122).
|
|
|
|
|
|
++ 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
