* net: tftp: fix type of block arg to store_blockJayachandran Chandrasekharan Nair2012-07-11-1/+1
| | | | | | | | | | | | | The block argument for store_block can be -1 when the tftp sequence number rolls over (i.e TftpBlock == 0), so the first argument to store_block has to be of type 'int' instead of 'unsigned'. In our environment (gcc 4.4.5 mips toolchain), this causes incorrect 'offset' to be generated for storing the block, and the tftp block with number 0 will be written elsewhere, resulting in a bad block in the downloaded file and a memory corruption.

* net: Make sure IPaddr_t is 32 bits in sizeMatthias Weisser2011-12-06-1/+1
| | | | | | | | | | | When building u-boot as 64 bit application (e.g. sandbox) ulong might be 64 bits in size. This breaks network code as IPaddr_t is 64 bytes in size then and an IPv4 address is 32 bits in size. This patch makes sure that IPaddr_t is always 32 bits in size. Also some warnings introduced by this patch are fixed. Signed-off-by: Matthias Weisser <weisserm@arcor.de> Acked-by: Mike Frysinger <vapier@gentoo.org>
* net: Add more #ifdefs for tftpput to reduce code sizeSimon Glass2011-10-27-1/+10

* net: Hide more code behind CONFIG_CMD_TFTPPUTSimon Glass2011-10-27-2/+4
| | | | | | | | This commit reduces code size a little by making the ICMP handler only available to tftpput. This is reasonable since it is the only user at present (ping just uses the normal handler). Signed-off-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | This is long over due. All but two net drivers have been converted, but those have now been dropped. The only thing left to do is actually delete all references to NET_MULTI and code that is compiled when that is not defined. So here we scrub the core code.

* 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.

* 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).

* tftp: get the tftp block size from config file and from the environmentAlessandro Rubini2009-08-25-2/+11
| | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The TftpStart() function modifies the 'BootFile' string when 'BootFile' contains both an IP address and filename (eg 1.2.3.4:/path/file). This causes subsequent calls to TftpStart to incorrectly parse the TFTP filename and server IP address to use. For example: => tftp 0x100000 10.52.0.62:/home/ptyser/non_existant Speed: 100, half duplex Using eTSEC1 device TFTP from server 10.52.0.62; our IP address is 10.52.253.79 ^^^^^^^^^^ CORRECT Filename '/home/ptyser/non_existant'. ^^^^^^^^^^^^^^^^^^^^^^^^^ CORRECT Load address: 0x100000 Loading: * TFTP error: 'File not found' (1) Starting again eTSEC2: No link.

* 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.

* Fix printf errors.Andrew Klossner2008-07-09-1/+1
| | | | | | | | | | | | The compiler will help find mismatches between printf formats and arguments if you let it. This patch adds the necessary attributes to declarations in include/common.h, then begins to correct the resulting compiler warnings. Some of these were bugs, e.g., "$d" instead of "%d" and incorrect arguments. Others were just annoying, like int-long mismatches on a system where both are 32 bits. It's worth fixing the annoying errors to catch the real ones. Signed-off-by: Andrew Klossner <andrew@cesa.opbu.xerox.com>

* Fix TFTP OACK code for short packets.Wolfgang Denk2007-08-31-2/+6
| | | | | | | | | | | The old code had a loop limit overflow bug which caused a semi- infinite loop for small packets, because in "i<len-8", "i" was signed, but "len" was unsigned, and "len-8" became a huge number for small values of "len".

| | | | | | | | | | | | The TFTP OACK code trusts that the incoming packet is formated as ASCII text and can be processed by string functions. It also has a loop limit overflow bug where if the packet length is less than 8, it ends up looping over *all* of memory to find the 'blksize' string. This patch solves the problem by forcing the packet to be null terminated and using strstr() to search for the sub string. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
