* TFTP: allow for adjustable retransmission timoutWolfgang Denk2010-03-21-5/+18
| | | | | | | | | | | | | So far, TFTP negotiated a fixed retransmission timeout of 5 seconds. In some cases (busy networks, slow TFTP servers) this caused very slow transfers. A new environment variable "tftptimeout" allows to set this timeout. Lowering this value may make downloads succeed faster in networks with high packet loss rates or with unreliable TFTP servers.

* Make getenv_IPaddr() globalDirk Behme2010-01-17-26/+0
| | | | | | | | | | | | | | | | | | | There are boards out there that do not have network support in U-Boot (CONFIG_CMD_NET not set), but they do so in Linux. This makes it desirable to be able to port network configuration (like the IP address) to the Linux kernel. We should not make the passing of the IP configuration to Linux dependent on U-Boot features / settings. For this, make getenv_IPaddr() global. This fixes build error u-boot/lib_xxx/board.c:360: undefined reference to `getenv_IPaddr' on various architectures.

* nfs: NfsTimeout() updatesEvan Samanas2009-12-07-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - NfsTimeout() does not correctly update the NFS timeout value which results in NfsTimeout() only being called once in certain situations. This can result in the 'nfs' command hanging indefinetly. For example, the command: nfs 192.168.0.1:/home/user/file will not exit until ctrl-c is pressed if 192.168.0.1 does not have an NFS server running. This issue is resolved by reinitializting the NFS timeout value inside NfsTimeout() when a timeout occurs. - Make the 'nfs' command print the 'T' character when a timeout occurs. Previously there was no indication that timeouts were occuring. - Mimic the 'tftpboot' command and when a download fails print "Retry count exceeded; starting again", and restart the download taking the 'netretry' environment variable into account.

* Add Transfer Size Option to tftpRobin Getz2009-08-25-2/+36
| | | | | | | | | | | | | | | Optionally add RFC 2349 "Transfer Size Option", so we can minimize the time spent sending data over the UART (now print a single line during a tftp transfer). - If turned on (CONFIG_TFTP_TSIZE), U-Boot asks for the size of the file. - if receives the file size, a single line (50 chars) are printed. one hash mark == 2% of the file downloaded. - if it doesn't receive the file size (the server doesn't support RFC 2349, prints standard hash marks (one mark for each UDP frame).

| | | | | | | | | | | Increasing the block size is useful if CONFIG_IP_DEFRAG is used. Howerver, the last fragments in a burst may overflow the receiving ethernet, so the default is left at 1468, with thre new CONFIG_TFTP_BLOCKSIZE for config files.

* net: defragment IP packetsAlessandro Rubini2009-08-25-5/+183
| | | | | | | | | | | | | | | | | The defragmenting code is enabled by CONFIG_IP_DEFRAG; the code is useful for TFTP and NFS transfers. The user can specify the maximum defragmented payload as CONFIG_NET_MAXDEFRAG (default 16k). Since NFS has a bigger per-packet overhead than TFTP, the static reassembly buffer can hold CONFIG_NET_MAXDEFRAG + the NFS overhead. The packet buffer is used as an array of "hole" structures, acting as a double-linked list. Each new fragment can split a hole in two, reduce a hole or fill a hole. No support is there for a fragment overlapping two diffrent holes (i.e., thre new fragment is across an already-received fragment).

| | | | | | | | | | | | In the previous enetaddr refactoring, the assumption with commit 56b555a644 was that the eth layer would handle the env -> device enetaddr syncing.

* NetLoop initialization bugMichael Zaidman2009-04-19-59/+4
| | | | | | | | | | | | | | | | | | | | The patch fixes the bug of partial initialization of global network parameters. Upon u-boot's start up the first ping command causes a failure of the consequent TFTP command. It happens in the recently added mechanism of the NetLoop initialization where initialization of global network parameters is separated in the NetInitLoop routine which is called per env_id change. Thus, ping request will initialize the network parameters necessary for ping operation only, afterwards the env_changed_id will be set to the env_id that will prevent all following initialization requests from other protocols. The problem is that the initialized by ping subset of network parameters is not sufficient for other protocols and particularly for TFTP which requires the NetServerIp also.

* net: Make TFTP server timeout configurableBartlomiej Sieka2008-10-18-4/+24
| | | | | | | | | | | | | | | | | | | | | | | | | There are two aspects of a TFTP transfer involving timeouts: 1. timeout waiting for initial server reply after sending RRQ 2. timeouts while transferring actual data from the server Since the upcoming auto-update feature attempts a TFTP download during each boot, it is undesirable to have a long delay when the TFTP server is not available. Thus, this commit makes the server timeout (1.) configurable by two global variables: TftpRRQTimeoutMSecs TftpRRQTimeoutCountMax TftpRRQTimeoutMSecs overrides default timeout when trying to connect to a TFTP server, TftpRRQTimeoutCountMax overrides default number of connection retries. The total delay when trying to download a file from a non-existing TFTP server is TftpRRQTimeoutMSecs x TftpRRQTimeoutCountMax milliseconds. Timeouts during file transfers (2.) are unaffected.
