2003-01-30  Jonathan Larmour  

        * src/sys/net/if_bridge.c (bridge_input): Learn source host addr,

        not dest host addr.

        Fix pointed to by Daniel Néri.

2002-12-14  Nick Garnett  

        * src/sys/netinet/tcp_usrreq.c (tcp_usrreq): Rearranged ifndef on

        PRU_SENSE case to keep the case in the switch and let it return a

        sensible result. Otherwise a stat() on a socket causes a panic().

2002-12-03  Gary Thomas  

        * src/ecos/support.c (show_network_tables): New function used

        to print network information (interface, routing).

2002-05-21  Jesper Skov  

        * src/lib/recv.c: Fix warning. socket.h declarations are not

        available to the kernel code. Added missing argument in the

        recvfrom call.

        changing macros to get the desired declarations, thus fixing

        compiler warnings.

2002-04-26  Gary Thomas  

        * src/sys/netinet/ip_input.c: Proper "extern" definition of 'ipstat'.

        * src/sys/netinet/raw_ip.c:

        * src/sys/netinet/ip_output.c:

        * include/netinet/ip_var.h: Use of ramdom IP packet id is optional.

2002-04-22  Gary Thomas  

        * src/sys/netinet/tcp_usrreq.c:

        * src/sys/netinet/tcp_output.c:

        * src/sys/netinet/tcp_input.c:

        * src/sys/netinet/tcp_debug.c:

        * include/netinet/tcp_debug.h: Fully conditionalize on TCPDEBUG.

2002-03-27  Jonathan Larmour  

        * doc/openbsd.sgml: Manpages now live in "common" BSD package.

2002-03-19  Gary Thomas  

        * src/sys/net/route.c (cyg_route_reinit): Renamed from route_reinit.

2002-03-11  Hugo Tyson  

        [Case 107110]

        * src/sys/netinet/in.c (in_control): SIOCSIFADDR switch entry

        moved to before the scan for this same address being in the list

        already, along with Add and Delete (SIOCAIFADDR,SIOCDIFADDR) arms.

        It falls through into the same alloc-if-needed code anyway.

        Thus repeatedly setting the same address does not leak store.

        * src/sys/net/route.c (route_reinit): Rewrite to delete all routes

        individually rather than en-masse (leaking store).

        (rt_reinit_rtdelete): New function; callback for individual

        deletion.

        (rtioctl): Do not pass in a "route **" to return a pointer to the

        route removed or added; this results in an extra reference, by the

        returned pointer, and so a storeleak.

        (rtrequest): RTM_DELETE arm: do not free a gateway route if the

        gateway pointer is the same as the route itself - it gets freed

        *again* at the end of the routine if you do.  Just dec the refcnt.

2002-03-07  Gary Thomas  

        * include/sys/param.h: Privatize route_reinit(), arc4random().

2002-02-28  Hugo Tyson  

2002-02-28  Martin Buck 

        * src/sys/net/if_ethersubr.c (ether_input): [Bugzilla 60318]

        ether_input() schedules processing by calling schednetisr(FOO) and

        then queues the frame afterwards.  Where we cannot be preempted

        eg. in a DSR or in the original BSD kernel, this is OK.  In eCos

        the call to schednetisr(FOO) might cause a context switch *before*

        the frame is enqueued.  This "jams" one packet in the queue,

        delaying it until the next packet, and so on.

        This change makes ether_input() store up the schednetisr() arg

        until the end, and do the call then, much like it does with the

        queue to use.  Thanks Martin!

2002-02-22  Hugo Tyson  

        * doc/openbsd.sgml: New file; separated stack-specific docs from

        monolithic net doc, and tidied up in various ways.

2002-02-15  Gary Thomas  

        * cdl/openbsd_net.cdl: Slight changes in layout required by split

        of network stacks.

2002-02-13  Jonathan Larmour  

2002-02-13  Andrew Lunn  

        * include/sys/mbuf.h: Declare variables as extern in header.

        * src/sys/kern/uipc_mbuf.c: Define mbtypes[] and init it.

2002-02-05  Hugo Tyson  

        * cdl/openbsd_net.cdl: Place this package below  CYGPKG_NET

        ie. the common networking package.  Only affects the view in the

        GUI CT, no big deal.

2002-01-28  Gary Thomas  

        * src/sys/netinet/ip_input.c: inet_ntoa() is now common.

        * cdl/openbsd_net.cdl: Renamed from net.cdl.  This package

        is now a proper sub-package, implementing a network stack.

2002-01-28  Jonathan Larmour  

        * cdl/net.cdl: Clarify CYGPKG_NET_ROUTING description.

2002-01-08  Jonathan Larmour  

        * tests/server_test.c (server_test): Correct port conversion.

2001-12-14  Hugo Tyson  

        * src/sys/net/if_ethersubr.c (ether_output): Never ever print

        anything!  It can recurse unexpectedly if debugging over net.

2001-12-10  Andrew Lunn 

        * cdl/net.cdl: Add configury to eliminate network timing stats.

        * src/include/machine/param.h: Timing statistics for things like

        memcpy, mbuf_alloc etc now use configury to determine if the

        statistics code should be compiled.

        * src/ecos/support.c: Ditto.

        * tests/nc_test_slave.c: Only print timing stats when they

        are enabled.

        * tests/tcp_echo.c: Ditto.

        * tests/nc_test_master.c: Allow building with SNMP lib which has

        its own gettimeofday(). This should be fixed better a different

        way but will do for now.

2001-12-06  Hugo Tyson  

        * src/lib/bootp_support.c (init_net): Just re-tabbed and checked

        the addition to initialize DNS from DHCP info - it had already

        snuck into the file in the previous change from Andrew.  Include

        of netdb.h added also, from the patch in Bug 57019.  Also check

        CYGINT_ISO_DNS for the setup code instead of CYGPKG_ISO_DNS.

2001-12-04  Jonathan Larmour  

        * src/lib/bootp_support.c: Check CYGINT_ISO_DNS (from

        ) instead of CYGPKG_ISO_DNS.

2001-12-03   Andrew Lunn  

        * src/lib/bootp_support.c: get_bootp_option(): Take the

        max length of data we want out of the bootp record.

        * src/lib/dhcp_prot.c: Pass the length we expect for an option.

2001-08-16  Anssi Pulkkinen 

        * src/lib/dhcp_prot.c: Make sure we use the newly calculated xid.

2001-08-02  Anand Srivastava 

        * src/lib/dhcp_prot.c do_dhcp: ID calculation must be done only

        once. moved it out the loop.

2001-11-21  Hugo Tyson  

        * src/lib/dhcp_support.c (dhcp_mgt_entry): If we have an

        SNMPAGENT, must recycle it whenever we reinitialize all

        interfaces; call SnmpdShutDown() to cause this.

        Also re-initialize all loopback interfaces here too.

2001-11-30  Hugo Tyson  

        * src/lib/dhcp_prot.c (set_default_dhcp_tags): New routine to

        insert all the extra woffle we need neatly each time, keeping the

        state machine's case arms to the real work.  The new thing this

        sets is TAG_DHCP_PARM_REQ_LIST, with a list that matches the

        default set we get from a LINUX dhcpd.  This is because M$ servers

        need explicit requests for eg. TAG_GATEWAY.  Note that I have

        included configuration to override the set of tags requested here

        in the source, but not yet backed up by CDL - we'll see whether

        anyone needs this.

        (set_variable_tag): New routine to insert a variable pointed-to

        data item rather than an int of 1,2 or 4 bytes.

        (do_dhcp): Call set_default_dhcp_tags() every time we send a

        packet, rather than ad hoc additions in each state.

2001-11-29  Jonathan Larmour  

        * include/machine/ansi.h: No longer require BSD string function

        compatibility macros (in fact they confuse things).

        * cdl/net.cdl: Require BSD compatibility functions from .

2001-11-19  Hugo Tyson  

        * include/bootp.h (BP_STD_TX_MINPKTSZ): New symbol defining the

        minimal DHCP packet size which we should send.

        * src/lib/dhcp_prot.c (scan_dhcp_size): New routine to scan up to

        the end of the packet, for length determination and padding.

        (dhcp_size): Now uses scan_dhcp_size().

        (dhcp_size_for_send): New, uses scan_dhcp_size() and pads with

        zero up to the min packet size that we should send.

        (do_dhcp): In every sendto() call, use dhcp_size_for_send(xmit) in

        order to send padded, full size packets as needed.  5 instances.

        Credit to "Anssi Pulkkinen"  for the

        original version of this patch.

2001-11-08  Jesper Skov  

        * tests/server_test.c (net_test): Fix compile error.

2001-11-02  Gary Thomas  

        * src/ecos/support.c:

        * include/machine/ansi.h: Add C++ support [externC].

2001-11-11  Andrew Lunn 

        *src/lib/recv.c: Implement the recv() call.

2001-10-29  Hugo Tyson  

        * src/sys/net/if_ethersubr.c (ether_output): [CASE 106613] Even if

        the queue is full, and we are dropping the packet, try to start

        the interface anyway, to give it a chance to empty the queue if

        the device has recovered from whatever made the queue fill up in

        the first place - being unplugged from the network for example.

        This change is belt & braces with a similar policy in the periodic

        tickle function in the logical ether driver in io/eth/... ; this

        change will recover the situation immediately if the application

        continues trying to send despite ENOBUFS.

2001-10-25  Hugo Tyson  

        * src/sys/net/if_bridge.c (bridge_broadcast): Count if_obytes in

        destination interfaces as well as the bridge interface; normally

        this is done in if_ethersubr.c but here we talk directly to the

        interface, bypassing that layer.  Thanks to Andrew Lunn for

        noticing that.

2001-10-18  Jonathan Larmour  

        * src/sys/netinet/in.c (in_lifaddr_ioctl): Silence warnings about

        trigraphs.

2001-10-10  Hugo Tyson  

        * tests/ftp_test.c (net_test): This was lacking #ifdefs for

        CYGHWR_NET_DRIVER_ETH0 and CYGHWR_NET_DRIVER_ETH1.  Ooops.

2001-10-05  Jonathan Larmour  

        * cdl/net.cdl (CYGPKG_NET_CFLAGS_ADD): Define __INSIDE_NET within

        this package to allow segregation of definitions only relevant for

        internal consumption, and definitions allowable for external

        consumption.

        * include/lib/libkern/libkern.h: Conditionalize on __INSIDE_NET.

2001-10-04  Jonathan Larmour  

        * cdl/net.cdl (CYGHWR_NET_DRIVER_ETH0): Make flavor bool so it isn't

        defined when 0.

        (CYGHWR_NET_DRIVER_ETH1): Ditto.

2001-10-04  Hugo Tyson  

        * src/lib/dhcp_support.c: Some conditional compilation tags were

        wrong vis a vis ETH1 versus ETH0.  Thanks to "Simon"

         for spotting it.

2001-10-04  Jesper Skov  

        * tests/multi_lo_select.c (cyg_user_start): Added CYG_TEST_INIT

        call.

        * tests/ping_lo_test.c (cyg_start): Same.

        * tests/tcp_lo_test.c (cyg_start): Same.

        * tests/udp_lo_test.c (cyg_start): Same.

        * tests/tcp_lo_select.c (cyg_start): Same.

2001-09-28  Jonathan Larmour  

        * cdl/net.cdl: Tell isoinfra we support getproto* and getserv*

        NS functionality.

        * include/netdb.h: Move to...

        * include/net/netdb.h: ...here.

2001-09-25  Jesper Skov  

        * cdl/net.cdl: Don't build tests/nc_test_master as it's a host

        side tool.

        * src/lib/getserv.c: Added domain service.

        * include/netdb.h: Moved getbyhost()/getbyaddr() declarations and

        hostent struct definition to the DNS package.

        * src/lib/gethost.c: Removed.

        * cdl/net.cdl: Removed gethost.c (replaced by proper

        implementation in CYGPKG_NS_DNS).

2001-09-17  Hugo Tyson  

2001-09-17  Andrew Lunn 

        * src/sys/net/if_bridge.c (bridge_broadcast): Fix a null pointer

        deference.  Supporting VLANs, it seems that during the net_init()

        function, it sends a packet to the bridge with the source

        interface being NULL.  Stats counting assumed otherwise.

2001-09-14  Jonathan Larmour  

        * src/sys/kern/uipc_syscalls.c: Last change to uipc_syscalls.c

        wasn't right. The parts that were __ECOS__ should simply have

        been completely removed.

2001-09-13  Hugo Tyson  

        * cdl/net.cdl: Add configury to control whether we can tickle the

        network devices if there's a lack of network traffic, and to

        control the delay time before so doing.

        * src/ecos/timeout.c (alarm_thread): Use a timed wait, if so

        configured, for the flag; and if it times out, tickle all the

        devices via the common ether driver routine for so doing.

2001-09-12  Jonathan Larmour  

        * include/sys/socketvar.h: Use __ECOS, not __ECOS__.

        * src/sys/kern/uipc_syscalls.c: Ditto.

        * src/sys/kern/uipc_socket2.c (sblock): Ditto.

2001-08-02  Jonathan Larmour  

        * tests/linux_echo.c (echo_test): Set socket options before bind.

        * tests/nc_test_slave.c (do_tcp_test): Ditto.

        * tests/server_test.c (server_test): Ditto.

        * tests/tcp_echo.c (echo_test): Ditto.

        * tests/tcp_lo_test.c (server): Ditto.

        * tests/tcp_sink.c (sink_test): Ditto.

        * tests/tcp_source.c (source_test): Ditto.

2001-07-27  Jonathan Larmour  

        * include/sys/select.h: Renamed to....

        * include/sys/bsdselect.h: New file.

        * include/sys/socketvar.h: Include  instead of

        * src/lib/select.c: Include 

2001-07-26  Jonathan Larmour  

        * cdl/net.cdl (CYGPKG_NET_API_LOCAL): Implements select()

        * include/sys/bsdtypes.h: No need for these select definitions.

2001-06-20  Grant Edwards 

2001-06-20  Hugo Tyson  

        * src/lib/dhcp_prot.c (alarm_function): Change the lease state

        before re-enabling the alarm so that if it somehow gets times of

        zero (ie. right now) it quickly completes the state machine rather

        than recursing to its doom.

        (new_lease): Test the retcode of get_bootp_option() and use

        obvious defaults if the T1 and T2 times are not provided - this is

        RFC compliant! - and use "infinite lease" if the lease time is not

        provided at all.

2001-06-19  Trenton D. Adams  

        * tests/server_test.c (server_test): Null terminate read string

        at right place.

2001-06-13  Jonathan Larmour  

        * cdl/net.cdl: Make debug output an option. Include DHCP.

        * src/lib/dhcp_prot.c: DHCP_CHATTER -> CYGDBG_NET_DHCP_CHATTER

        * src/ecos/support.c (cyg_kmem_init): Only print debug output if

        requested.

        * cdl/net.cdl: Make requirements on other eCos features more

        abstract.

2001-05-09  Robin Farine 

2001-05-09  Hugo Tyson  

        * src/lib/dhcp_prot.c (do_dhcp): In DHCPSTATE_INIT case, create a

        new xid.  Servers apparantly can use *only* this to distinguish

        machines, even with different MAC addresses!  Therefore we use

        both the most sensitive randomizer available (arc4random()) which

        in reality uses a finegrain clock, and salt the value further with

        the MAC address itself.  Thanks again Robin.

        * src/ecos/support.c (arc4random): Make arc4random not always be a

        multiple of 256; stir the clock into the low bits also.

2001-05-09  Robin Farine 

2001-05-09  Hugo Tyson  

        * src/sys/net/if_bridge.c: Patch from Robin; the route aging

        process took twice as long to timeout because an entry requires

        *two* executions of bridge_rtage() to actually get removed.

        Record the timeout over 2 to fix that and also define

        BRIDGE_RTABLE_TIMEOUT as 300s that the standard specifies as

        default aging time.

2001-05-09  Hugo Tyson  

        * src/lib/getserv.c (setreturned): New routine to set up a copy of

        the service data with the port converted to network order like the

        API demands.  It's this way to make the initialization of the

        table most readable.

        (services[]): Added an entry for snmp.

        (getservbyname): Use setreturned() to return adjusted info.

        (getservbyport): Use setreturned() to return adjusted info and

        compare with host-ordered version of the port.

        * src/lib/tftp_client.c (tftp_get):

        (tftp_put): Do not convert to net order from

        the getserv structure; it's already net order.

        * src/lib/tftp_server.c (tftpd_server): Convert the socket into

        host order; it's network order in the getserv API.

        * tests/ftp_test.c (ftp_test): Do not convert to net order from

        the getserv structure; it's already net order.

        * tests/tftp_client_test.c (PUTFILE): Changed the names of the

        test files to be fully qualified, this makes the test work with

        more server machines.  /tftpboot/tftp_get and /tftpboot/tftp_put.

2001-04-24  Bart Veer  

        * cdl/net.cdl:

        Prevent multiple device drivers from implementing the

        same eth0/eth1 device.

2001-03-30  Jonathan Larmour  

        * cdl/net.cdl (CYGPKG_NET_SYSCTL): Comment out - currently unsupported.

2001-03-28  Richard Panton  

        * include/bootp.h: Define func protos with C linkage

        * include/netdb.h: Ditto

        * include/network.h: Ditto

        * include/tftp_support.h: Ditto

        * src/lib/getserv.c: getservbynumber() -> getservbyport()

2001-03-12  Gary Thomas  

        * src/lib/network_support.c (init_all_network_interfaces):

        FIx slightly broken previous attempt in abort code.

2001-03-11  Gary Thomas  

        * src/lib/network_support.c (init_all_network_interfaces):

        Let initialization of PCMCIA devices abort after ~5 seconds.

2001-02-23  Jonathan Larmour  

        * src/lib/tftp_server.c (STACK_SIZE): Align

2001-02-20  Jonathan Larmour  

        * cdl/net.cdl: Avoid puts to the CDL header when a CDL

        define will do.

        Rename CYGPKG_NET_BRIDGE_CODE -> CYGPKG_NET_BRIDGE

        Rename CYGPKG_NET_NBRIDGE -> CYGNUM_NET_BRIDGES

        Rename CYGPKG_NET_BRIDGE_HANDLER -> CYGINT_NET_BRIDGE_HANDLER

        Make if_bridge.c compilation conditional on CYGPKG_NET_BRIDGE

        * src/sys/net/if_bridge.c: Reflect above renames.

2001-02-20  Hugo Tyson  

2001-02-15  Martin Buck  

        * cdl/net.cdl: Split up CYGPKG_NET_NBRIDGE into 2 parts:

        CYGPKG_NET_NBRIDGE and CYGPKG_NET_BRIDGE_HANDLER. If

        CYGPKG_NET_BRIDGE_HANDLER is nonzero, calls to an Ethernet

        bridge are inserted into the stack's data path. If

        CYGPKG_NET_NBRIDGE is nonzero, the standard OpenBSD bridge

        code is added. This setup allows you to implement your own

        bridge as a separate package which then implements

        CYGPKG_NET_BRIDGE_HANDLER so it gets called by the stack.

        NBRIDGE now is the same as CYGPKG_NET_BRIDGE_HANDLER instead

        of CYGPKG_NET_NBRIDGE. This means it's nonzero if the bridge

        is wanted, but it no longer contains the number of bridge

        buffers requested. This shouldn't be a problem, because the

        only place where the actual number of buffers is required is

        in if_bridge.c, which now uses CYGPKG_NET_NBRIDGE instead

        of NBRIDGE.

        * src/sys/net/if_bridge.c: Use CYGPKG_NET_NBRIDGE instead of

        NBRIDGE, because the latter one now only means that there is

        a bridge, not that we should implement it.

2001-01-07  Gary Thomas  

        * src/ecos/support.c:

        * cdl/net.cdl:  Add interface 'CYGPKG_NET_DRIVER_FRAMEWORK'

        to describe interdependencies between network stack and driver

        framework packages.

2001-01-03  Hugo Tyson  

        * tests/linux_echo.c: New file to test for network bandwidth

        limitations in host side.  Builds to a linux version of the

        tcp_echo middleman.

        * tests/make.linux (all): Build linux_echo.

2001-01-03  Hugo Tyson  

        * include/dhcp.h (struct dhcp_lease): Define the semaphore pointer

        field in each lease structure.

        * src/lib/dhcp_support.c: Initialize the dhcp_lease structs to

        point to the semaphore "dhcp_needs_attention".

        * src/lib/dhcp_prot.c (alarm_function): Post to the semaphore

        pointed to in the lease structure, rather than one hard-coded.

        This is much cleaner, in that dhcp_prot.c now uses no external

        variables, all state goes through the API.

2000-11-15  Hugo Tyson  

        * src/lib/bootp_support.c (init_net): Do a SIOCSIFADDR a 2nd time

        after setting the netmask (SIOCSIFNETMASK) in order for the newly

        set netmask to "take" - otherwise a bogus route based on the

        default netmask lurks within the system.

2000-11-10  Hugo Tyson  

        * src/ecos/support.c (cyg_net_get_mem_stats): New API for getting

        info on the various mem pools the stack uses to enable tests to

        spot store leaks.

        * include/network.h (cyg_net_get_mem_stats): Export this API for

        automated network testing.

2000-10-24  Hugo Tyson  

        * src/lib/tftp_server.c (tftpd_server): Cut down the chatter to

        nothing (unless there's an error) if running automated testing.

2000-10-17  Hugo Tyson  

2000-10-10  Andrew Lunn 

        * src/ecos/support.c (setsoftnet,cyg_panic): Less chatter,

        particularly not when we're out of MBUFs.

2000-10-17  Hugo Tyson  

2000-10-10  Andrew Lunn 

        * src/sys/net/if_bridge.c: Intergrated a more up to date version

        from the OpenBSD sources. This fixes a few bugs.

2000-10-17  Hugo Tyson  

        * src/ecos/support.c (cyg_ktime_init): Start time at 1 Second so

        that all visible time values are valid; offset time by 1 Second

        subsequently, for ever.

        * src/sys/netinet/if_ether.c (arpresolve): Undo the change below;

        instead make "kernel time" be valid ie. more than 1 second into

        its life.  Dumb stack assumes it takes UNIX-like time to start.

2000-10-16  Hugo Tyson  

        * src/sys/netinet/if_ether.c (arpresolve): Deal with the initial

        case when the route timeout is zero (as initialized).  Otherwise

        it never actually sent out the initial ARP request packet.  This

        caused connect() not to work, and thus ftp_test, for example.

        * src/lib/dhcp_support.c (dhcp_start_dhcp_mgt_thread): Also

        initialize the dhcp semaphore here.  The other place it is init'd

        [correctly] didn't fire if we use the standard support.  Fixed

        some absent return value warnings.

2000-10-10  Hugo Tyson  

        * src/lib/tftp_server.c (tftpd_server): Modify the server to

        support multiple sessions - ie. starting N servers at once.

        Mainly this means closing the initial socket whilst servicing a

        request, so that another server can then bind to it; tell another

        server to retry that bind via a semaphore, that it waited on when

        the bind failed initially, rather than just returning.

        * src/lib/tftp_dummy_file.c (dummy_open): Trivial bugfix: scan the

        list of files as well as incrementing the counter.

2000-10-05  Andrew Lunn 

        * src/ecos/support.c (cyg_ktime_func,cyg_ktime_init,cyg_net_init):

        Make 'ktime' value valid.

2000-10-05  Hugo Tyson  

        * src/lib/tftp_server.c (tftpd_write_file): Restructure this

        function to match the loop layout of the tftpd_read_file; so that

        it retries sensibly, and so that a delayed/duplicated packet does

        not cause a doubling of all traffic with a less smart host.

2000-10-05  Hugo Tyson  

        * include/tftp_support.h (TFTP_TIMEOUT_MAX): Change this to 50; it

        refers to total timeouts for a whole session, so it should be

        greater than the retry count for each packet.

2000-10-05  Hugo Tyson  

        * src/lib/tftp_dummy_file.c: Make the fake file slots be a Mb

        instead of 10k so that you can do meaningful timing tests with it.

        (dummy_open): Allow re-write of an existing file so that you can

        do repeated put tests without running out of slots.

2000-10-05  Hugo Tyson  

        * src/lib/select.c (_cyg_select): Unlock the scheduler in a couple

        of other places I missed.  Doh.

2000-09-28  Hugo Tyson  

        * src/lib/select.c (_cyg_select): Elect to wait for the flags

        atomically wrt sockets possibly becoming ready - this was a race

        condition that would apparently delay a packet until another

        arrived, eg. a tftp retry.  Then two came along all at once.

2000-09-28  Hugo Tyson  

        * src/lib/tftp_server.c: Add lots of instrumentation for

        debugging.  It's switched off, and doesn't have a real config opt,

        though it easily could have.

2000-09-26  Hugo Tyson  

        * src/lib/tftp_server.c (tftpd_read_file): Doh! TFTP_TIMEOUT is an

        internal API thing, not an error we can send in an ERROR packet.

        * include/tftp_support.h: Comment to this effect.

2000-09-26  Hugo Tyson  

2000-09-25  Andrew Lunn 

        * src/lib/tftp_server.c: Send an ERROR packet when giving up after

        too many timeouts.  This should cause the client to give up as

        well.  Also moved all the replicated code to send an ERROR packet

        into one function.

        [Huge] I collected another point where we can use the common

        function also, and used ETIMEOUT instead of EBADOP for the new

        error packet returns. Thanks Andrew!

2000-09-14  Hugo Tyson  

        * cdl/net.cdl (CYGOPT_NET_DHCP_DHCP_THREAD_PARAM): Set default to

        1 so that the DHCP management thread loops forever.  This allows

        it to recover from a DHCP renewal failure.

        * src/lib/dhcp_prot.c (next_timeout): Harden the DHCP protocol

        machine against [simulated] failures - otherwise the tests with

        simulated failures tend just to close down all the interfaces when

        DHCP packets are lost.

2000-09-11  Gary Thomas  

        * src/lib/bootp_support.c (init_net): Set default route correctly.

2000-09-01  Hugo Tyson  

        * src/ecos/support.c (cyg_net_init): You can't print things while

        initializing the network!  Well, not if connected to GDB over the

        network anyway.  The printf("Init device '%s'...); removed.

2000-09-01  Hugo Tyson  

        * OVERVIEW: This is part of the change to the network stack to

        greatly reduce latencies both of (other) DSRs and of thread

        scheduling.  All the work that the network stack *and* individual

        ether drivers used to do in DSRs (including alarm callbacks and

        data copies to/from the device memory) is moved into a "fast

        network thread" instead.  It calls a device's "deliver" function

        to do the work that was previously in the DSR.  This is a separate

        thread so that it can be set higher priority than application

        threads in order to minimize packet loss (depending on the

        driver), if required (the application threads presumed to be

        higher priority in turn than the network thread).  A crucial

        consequence of this is that we are no longer locking against DSRs,

        so a plain mutex can be used rather than the global scheduler

        lock, thus simplifying all the splfoo/splx() style functions.

        * src/ecos/timeout.c (alarm_thread): Addition of the "fast network

        thread" which runs DSR-like activities.

        (do_timeout): Timeout function morphed for calling from that.

        (do_alarm, ecos_synch_eth_drv_dsr): new DSR functions to signal to

        the thread.

        (timeout): Race condition fixed.  splinternal() used for locking

        instead of scheduler.

        * src/ecos/support.c (cyg_net_init): Splfoo/splx() functions,

        together with tsleep/wakeup functions, all removed to separate

        them from the mixed bag of utilities in this file.  What remains

        is mbuf wrapper routines and the like, plus the network "netisr"

        thread itself, the caller into the stack that does the slower

        priority work.

        * src/ecos/synch.c: New file; implemtation of new splfoo/splx()

        functions, together with tsleep/wakeup functions, since they are

        related now.

        * cdl/net.cdl: Compile new file synch.c; two new options, one for

        "fast thread" priority, and one for DHCP manager thread priority,

        as I was adding prio configury.  CYGPKG_NET_FAST_THREAD_PRIORITY

        and CYGPKG_NET_DHCP_THREAD_PRIORITY resp, with suitable default

        values relative to the CYGPKG_NET_THREAD_PRIORITY.

        * src/lib/dhcp_support.c (dhcp_start_dhcp_mgt_thread): Use the

        configured priority rather than just "net thread - 1"

2000-08-31  Hugo Tyson  

        * tests/tcp_echo.c: Change the priorities of the main and loading

        threads to accommodate the network having helper threads around at

        adjacent priorities to its main thread prio.

2000-08-24  Hugo Tyson  

        * src/sys/net/if.c (ifioctl): Support the two new ioctl() keys; at

        this level, the struct ifreq at the head of the data area must be

        filled to select an interface.

        * include/sys/sockio.h (SIOCGIFSTATSUD): Add two new eCos-only

        ioctl() keys, SIOCGIFSTATSUD and SIOCGIFSTATS, for reading

        statistical information out of ethernet devices, for SNMP. This

        should allow SNMP (a) to not explode, (b) to get useful info out

        of other device implementations than this one.

2000-08-17  Hugo Tyson  

        * src/ecos/timeout.c (timeout): Rework the timeout system to

        record last-time-we-set-the-alarm and whence values, so that new

        timeouts being added can be set up relative to the correct

        absolute time.  Otherwise adding a new timeout sets them *all*

        into the future by the expired portion of the previous minimum

        pending timeout.  Also deal better with recursion ie. timeout

        handlers themselves setting new timeouts as is only natural.

        Lots of asserts too.

        * src/ecos/support.c (cyg_splsoftnet): Use the new kernel facility

        to lock mutex &c atomically, with the scheduler locked already.

        (cyg_tsleep): Similarly, and reclaim the mutex likewise.

        Also added lots of asserts to both calls the better to document

        what's going on.

2000-08-17  Hugo Tyson  

        * src/lib/tftp_server.c: Fix contributors field.

2000-08-16  Hugo Tyson  

        * src/lib/tftp_server.c: Improvements to server wrt better error

        messages and detection of filesystem errors eg. on close-file.

        Contrib from ASCOM.  I tidied up some comments and indent to

        minimize the diff.  [CASE 104354]

2000-08-15  Hugo Tyson  

        * doc/bridge.html: New file...

        * doc/bridge.doc: New file...

        provided by ASCOM from the OpenBSD version.

2000-08-15  Hugo Tyson  

        * src/sys/net/if_bridge.c (bridge_ioctl): SIOCBRDGSTO takes

        argument in seconds not in ticks.  So move around some mul/div by

        hz ops to get this right.

2000-08-14  Gary Thomas  

        * src/ecos/support.c: Use new table definition mechanism.

2000-07-27  Hugo Tyson  

        * src/lib/dhcp_prot.c (do_dhcp): Use xmit->bp_htype =

        HTYPE_ETHERNET rather than ifr.ifr_hwaddr.sa_family; sa_family is

        in a different namespace, despite appearances.

        * src/lib/bootp_support.c (do_bootp): Use bp_htype =

        HTYPE_ETHERNET rather than ifr.ifr_hwaddr.sa_family; sa_family is

        in a different namespace, despite appearances.

2000-07-27  Nick Garnett  

        * cdl/net.cdl: Require the C library STDIO package to be present

        if there is more than one loopback interface. This is because it

        needs sprintf() to form the interface names.

        * src/sys/net/if_loop.c (loopattach):

        Only use sprintf() to form the loopback interface names when there

        is more than one. The CDL ensures that this will work.

        * src/lib/network_support.c:

        Added diag_printf() version of perror() for when STDIO package is

        absent.

        Only use sprintf() to form the loopback interface names when there

        is more than one. The CDL ensures that this will work.

        * tests/multi_lo_select.c:

        * tests/ping_lo_test.c:

        * tests/tcp_lo_test.c:

        Removed dependence on C library by adding a substitute perror()

        based on diag_printf() that is enabled when the STDIO package is

        absent.

2000-07-26  Hugo Tyson  

        * src/lib/dhcp_prot.c (do_dhcp): Set the broadcast flag where

        necessary, and the client address too.  This makes it talk to a

        greater range of servers OK.

2000-07-25  Nick Garnett  

        * tests/multi_lo_select.c: Changed definition of NLISTENERS to

        work correctly with FILEIO package.

        * src/sys/net/if_loop.c (loopattach): Changed initialization of

        if_xname to "lo0".

        * src/ecos/support.c (cyg_net_init): Removed redundant code to

        initialize loop-back interface.

2000-07-25  Hugo Tyson  

        * src/lib/getserv.c: Add a list terminator record with NULLs in it

        so that the search finishes (without throwing asserts about bad

        strings).

2000-07-21  Hugo Tyson  

        * src/sys/net/if_bridge.c: Move the include of stdio.h lower,

        apparently it confuses local x86 compilers if their host tree is

        malformed.  Or something.

2000-07-21  Hugo Tyson  

        * cdl/net.cdl: Add a lot of description about the way the various

        fields are used in interface initialization: specifically that

        "server" so-called is just "someone to talk to" in the absence of

        bootp - and our tests depend on it!

        * src/lib/bootp_support.c (init_net): Only set up a route if the

        route address is nonzero - or all manner of confusion occurs with
