2016-05-27efi_loader: Add network access supportAlexander Graf
We can now successfully boot EFI applications from disk, but users may want to also run them from a PXE setup. This patch implements rudimentary network support, allowing a payload to send and receive network packets. With this patch, I was able to successfully run grub2 with network access inside of QEMU's -M xlnx-ep108. Signed-off-by: Alexander Graf <agraf@suse.de>
2015-10-28net: TFTP: variables cleanup and additionAlbert ARIBAUD \(3ADEV\)
TFTP source and destination port variable names are 'tftpsrcp' and 'tftpdstp' in the code, but 'tftpsrcport' and 'tftpdstport' in the README file. Fix the README. Add environment variable 'tftptimeoutcountmax'. As per the comments about the global variable tftp_timeout_count_max, make sure tftptimeoutcountmax is nonnegative. Introduce configuration option CONFIG_NET_TFTP_VARS, which controls whether environment variables tftpblocksize, tftptimeout, and tftptimoueoutcountmax are read by the TFTP client code. CONFIG_NET_TFTP_VARS defaults to y but can be set to n by targets with to tight size contraints. Make bf527-ezkit set CONFIG_NET_TFTP_VARS to n to keep the target size below limit.
2015-09-09net: Revert "tftp: adjust settings to be suitable for 100Mbit ethernet"Bin Meng
Commit 620776d "tftp: adjust settings to be suitable for 100Mbit ethernet" causes the following error message when trying to load a file using 'tftp' command via a tftp server. TFTP error: 'Unsupported option(s) requested' (8) This is due to with commit 620776d changes, the tftp option 'timeout' value is now set to zero which is an invalid value as per RFC2349 [1]. Valid values range between "1" and "255" seconds, inclusive. With some tftp servers that strictly implement the RFC requirement, it reports such an error message. Revert commit 620776d for RFC compliance. [1] https://www.ietf.org/rfc/rfc2349.txt Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Joe Hershberger <joe.hershberger@ni.com>

2015-08-21tftp: adjust settings to be suitable for 100Mbit ethernetPavel Machek
Adjust timouts and retry counts to be suitable for loaded ethernet network. With 5 seconds timeout, 10 retries maximum, tftp is impossible even on local network with single full-speed TCP connection. 100msec timeout should be suitable for most networks tftp is used on, that is local ethernets. Timeout count really needs to be way higher, as lost packets are normal when TCP is running over the same network. Enforce 10msec minimum.

2015-08-12tftp.c: fix CONFIG_TFTP_TSIZE for small filesMax Krummenacher
CONFIG_TFTP_TSIZE should limit a tftp downloads progress to 50 '#' chars. Make this work also for small files. If the file size is small, i.e. smaller than 2 tftp block sizes the number of '#' can get much larger. i.e. with a 1 byte file 65000 characters are printed, with a 512 byte file around 500. When using CONFIG TFTP BLOCKSIZE together with CONFIG_IP_DEFRAG the issue is more notable.

2012-07-11net: tftp: fix type of block arg to store_blockJayachandran Chandrasekharan Nair
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.

2010-03-21TFTP: allow for adjustable retransmission timoutWolfgang Denk
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.
