Log: Add 'netserver' command to EFI loader. In some environments is difficult to access bootp/dhcp configuration as "standard user". Add a command that allows to set or display the URI of the network server used as "net:" device. Currently only tftp and nfs protocols are supported. Typical usage pattern is: netserver tftp://192.168.168.1/path_to_obj_dir/arm.armv7/sys/GENERIC/ boot net:kernel Reviewed by: imp, kevans MFC after: 4 weeks Differential Revision: https://reviews.freebsd.org/D26736 Modified: head/stand/efi/loader/main.c Modified: head/stand/efi/loader/main.c ============================================================================== --- head/stand/efi/loader/main.c Wed Oct 14 12:28:54 2020 (r366699) +++ head/stand/efi/loader/main.c Wed Oct 14 13:13:14 2020 (r366700) @@ -40,10 +40,14 @@ __FBSDID("$FreeBSD$"); #include <sys/zfs_bootenv.h> #endif #include <paths.h> +#include <netinet/in.h> +#include <netinet/in_systm.h> #include <stdint.h> #include <string.h> #include <setjmp.h> #include <disk.h> +#include <dev_net.h> +#include <net.h> #include <efi.h> #include <efilib.h> @@ -1594,3 +1598,34 @@ command_chain(int argc, char *argv[]) } COMMAND_SET(chain, "chain", "chain load file", command_chain); + +extern struct in_addr servip; +static int +command_netserver(int argc, char *argv[]) +{ + char *proto; + n_long rootaddr; + + if (argc > 2) { + command_errmsg = "wrong number of arguments"; + return (CMD_ERROR); + } + if (argc < 2) { + proto = netproto == NET_TFTP ?
