| | | | | | | | | | | | | | | | While it sounds like a good idea to extract the RFC1048 data from PXE, in the end it is not and it is causing lots of issues. Our pxeloader might need options which are incompatible with other pxe servers (for example iPXE, but not only). Our pxe loaders are also now settings their own user class, so it is useful to issue our own pxe request at startup Reviewed by: tsoome Differential Revision: https://reviews.freebsd.org/D10953 Notes: svn path=/head/; revision=318990

This time decide on a proper URI parser rather than hacks. root-path can now be define the following way: For tftpfs: tftp://ip/path tftp:/path (this one will consider the tftp server is the same as the one where the pxeboot file was fetched from) For nfs: nfs:/path nfs://ip/path The historical ip:/path /path are kept on NFS Reviewed by: tsoom, rgrimes Differential Revision: https://reviews.freebsd.org/D10947 Notes: svn path=/head/; revision=318987

* loader: network read reworkToomas Soome2017-05-061-4/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current read from network is working from up to down - we have some protocol needing the data from the network, so we build the buffer space for that protocol, add the extra space for headers and pass this buffer down to be filled by nif get call in hope, we have guessed the incoming packet size right. Amazingly enough this approach mostly does work, but not always... So, this update does work from down to up - we allocate buffer (based on MTU or frame size info), fill it up, and pass on for upper layers. The obvious problem is that when we should free the buffer - if at all. In the current implementation the upper layer will free the packet on error or when the packet is no longer needed. While working on the issue, the additional issue did pop up - the bios implementation does not have generic get/put interface but is using pxe udpsend/udpreceive instead. So the udp calls are gone and undi interface is implemented instead. Which in turn means slight other changes as we do not need to have duplicated pxe implementation and can just use dev_net. To align packet content, the actual read from nic is using shifted buffer by ETHER_ALIGN (2).

| | | | | | | | | | | | | | | | | Don't use DHCP 150 option to decide which protocol use to netboot. When root-path includes ip address - go thru NFS, if ip address not exists in root-path - go thru TFTP from server which ip address is in next-server. But there is one limitation - only one tftp server in network to provide loader and everything else. Does enybody use more than only one?

"path" then the IP of the tftp server will be the one passed by the option 150, and the files will be retrieved under "path" on the tftp server 2. "ip:path" then the IP of the tftp server will be the one passed in the option "overwritting the IP from the option 150. We could not "abuse" the rootpath option in the form or tftp://ip:path because this is already used for other purpose by iPXE preventing any chainload from iPXE to the FreeBSD loader. Given at each open(), the loader loops over all available filesystems and keep the "best" error, we needed to prevent tftpfs to fallback on nfs and vice versa. the tftpfs and nfs implementation in libstand now return EINVAL early if 'netproto' for that purpose.

| | | | | | | | | | | | | | | | | | | | than bootp and rarp. The code which splits a serverip:/rootpath string into rootip and a plain pathname is now a separate net_parse_rootpath() function that can be called by others. The code that sets the kernel env vars needed for nfs_diskless is moved into net_open() so that the variables get set no matter where the params came from. There was already code in net_open() that allowed for the possibility that some other entity has set up the network-related global variables. It uses the rootip variable as the key, assuming that if it is set all the other required variables are set too. These changes don't alter the existing behavior, they just make it easier to actually write some new code to get the params from another source (such as the U-Boot environment).

* - Add code allowing a network device to only be open and closed onceMarius Strobl2010-01-091-9/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | by keeping it opened after the first open and closing it via the cleanup handler when NETIF_OPEN_CLOSE_ONCE is defined in order to avoid the open-close-dance on every file access which with firmware that for example performs an auto-negotiation on every open causes netbooting to take horribly long. Basically the behavior with this knob enabled resembles the one employed between r60506 and r177108 (and for sparc64 also again since r182919) with the addition that the network device now is closed eventually before entering the kernel and before rebooting. Actually I think this should be the desired MI behavior, however the U-Boot loader actually requires net_close() to be called after every transaction in order for some local shutdown operations to be performed (and which I think thus will break on concurrent opens, i.e. when netdev_opens is > 1, like the loader does at least for disks when LOADER_GZIP_SUPPORT is enabled). - Use NETIF_OPEN_CLOSE_ONCE to replace the hack, which artificially increased netdev_opens for sparc64 in order to keep the network device opened forever, as at least some firmware versions require the network device to be closed eventually before entering the kernel or otherwise will DMA received packets to stale memory. The powerpc OFW loader probably wants NETIF_OPEN_CLOSE_ONCE to be set as well for the same reasons. Notes: svn path=/head/; revision=201932
