2016-09-09Revert "net: nfs: Use the tx buffer to construct rpc msgs"Joe Hershberger
This reverts commit 998372b4798fd7ebb666f571950df925b8d80f69. This caused a data abort on some platform. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Reported-by: Guillaume GARDET <guillaume.gardet@free.fr>
2016-08-22net: nfs: Simplify rpc_add_credentials()Joe Hershberger
We use an empty hostname, so remove all the "processing" of the known-to-be-empty hostname and just write 0's where needed. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
2016-08-22net: nfs: Use the tx buffer to construct rpc msgsJoe Hershberger
Instead of always allocating a huge temporary buffer on the stack and then memcpy()ing the result into the transmit buffer, simply figure out where in the transmit buffer the bytes will belong and write them there directly as each message is built. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
2016-08-22net: nfs: Move some prints to debug statementsJoe Hershberger
Much of the information is verbose and derived directly from the environment. Only output in debug mode. This also saves about 300 bytes from the code size. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
2016-08-22net: nfs: Use consistent names for the rpc_pktJoe Hershberger
Use the same name throughout the nfs code and use the same member of the union to avoid casts. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
2016-08-22net: nfs: Correct a commentJoe Hershberger
The buffer is of 32-bit elements, not bytes. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
2016-08-22net: nfs: Consolidate handling of NFSv3 attributesJoe Hershberger
Instead of repeating the same large snippet for dealing with attributes it should be shared with a helper function. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>

2016-08-22net: nfs: Share the file handle buffer for v2 / v3Joe Hershberger
The v3 handles can be larger than v2, but that doesn't mean we need a separate buffer. Reuse the same (larger) buffer for both. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
2016-08-22net: NFS: Add NFSv3 supportGuillaume GARDET
This patch enables NFSv3 support. If NFSv2 is available use it as usual. If NFSv2 is not available, but NFSv3 is available, use NFSv3. If NFSv2 and NFSv3 are not available, print an error message since NFSv4 is not supported. Tested on iMX6 sabrelite with 4 Linux NFS servers: * NFSv2 + NFSv3 + NFSv4 server: use NFSv2 protocol * NFSv2 + NFSv3 server: use NFSv2 protocol * NFSv3 + NFSv4 server: use NFSv3 protocol * NFSv3 server: use NFSv3 protocol Signed-off-by: Guillaume GARDET <guillaume.gardet@free.fr> Cc: Tom Rini <trini@konsulko.com> Cc: joe.hershberger@ni.com Acked-by: Joe Hershberger <joe.hershberger@ni.com>
2016-08-22net: nfs: Remove separate buffer for default nameJoe Hershberger
There is no reason to store the default filename in a separate buffer only to immediately copy it to the main name buffer. Just write it there directly and remove the other buffer. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>

2015-04-18net: cosmetic: Name ethaddr variables consistentlyJoe Hershberger

2015-04-18net: cosmetic: Change IPaddr_t to struct in_addrJoe Hershberger
This patch is simply clean-up to make the IPv4 type that is used match what Linux uses. It also attempts to move all variables that are IP addresses use good naming instead of CamelCase. No functional change. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Acked-by: Simon Glass <sjg@chromium.org>
2015-04-18net: Access mapped physmem in net functionsJoe Hershberger
Previously the net functions would access memory assuming physmem did not need to be mapped. In sandbox, that's not the case. Now we map the physmem specified by the user in loadaddr to the buffer that represents that space. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2013-06-24net: nfs: add dynamic wait periodMatthias Brugger
This patch tackles the time out problem which leads to break the boot process, when loading file over nfs. The patch does two things. First of all, we just ignore messages that arrive with a rpc_id smaller then the client id. We just interpret this messages as answers to formaly timed out messages. Second, when a time out occurs we double the time to wait, so that we do not stress the server resending the last message.

2012-07-12net: nfs: make NFS_TIMEOUT configurableTetsuyuki Kobayashi
NFS_TIMEOUT is constant value defined in net/nfs.c. But sometimes it needs to adjust. This patch enables to override NFS_TIMEOUT by defining CONFIG_NFS_TIMEOUT in a board specific config file. Signed-off-by: Tetsuyuki Kobayashi <koba@kmckk.co.jp>
2012-05-23net: Refactor to separate the UDP handler from the ARP handlerJoe Hershberger

2011-12-06net: Make sure IPaddr_t is 32 bits in sizeMatthias Weisser
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.

2011-10-05net: drop !NET_MULTI codeMike Frysinger
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.

2009-12-07nfs: NfsTimeout() updatesEvan Samanas
- 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.

2009-08-07minor debug cleanups in ./netRobin Getz
Minor ./net cleanups - no functional changes - change #ifdef DEBUG printf(); #endif to just debug() - changed __FUNCTION__ to __func__ - got rid of extra whitespace between function and opening brace - removed unnecessary braces on if statements gcc dead code elimination should make this functionally/size equivalent when DEBUG is not defined.

2008-10-18net: express the first argument to NetSetTimeout() in millisecondsBartlomiej Sieka
Enforce millisecond semantics of the first argument to NetSetTimeout() -- the change is transparent for well-behaving boards (CFG_HZ == 1000 and get_timer() countiing in milliseconds). Rationale for this patch is to enable millisecond granularity for network-related timeouts, which is needed for the upcoming automatic software update feature. Summary of changes: - do not scale the first argument to NetSetTimeout() by CFG_HZ - change timeout values used in the networking code to milliseconds Signed-off-by: Rafal Czubak <rcz@semihalf.com> Signed-off-by: Bartlomiej Sieka <tur@semihalf.com> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>
