This reverts commits 47b2bee3ef
and 8d3c4544ff. It is not safe
to free allocated cards, dangling pointers main remain. Such
cleanup requires more changes in net core.
It enables net boot even when there is no bootp/dhcp server.
* grub-core/net/drivers/ieee1275/ofnet.c: Add grub_ieee1275_parse_bootpath and
call it at grub_ieee1275_net_config_real.
* grub-core/kern/ieee1275/init.c: Add bootpath to grub_ieee1275_net_config.
* include/grub/ieee1275/ieee1275.h: Likewise.
* Makefile.util.def (grub-mount): Add LIBGEOM to ldadd.
* grub-core/net/drivers/emu/emunet.c: Only include Linux-specific
headers on Linux.
(GRUB_MOD_INIT): Return immediately on non-Linux platforms; this
implementation is currently Linux-specific.
* util/getroot.c (exec_pipe): Define only on Linux or when either
libzfs or libnvpair is unavailable.
(find_root_devices_from_poolname): Remove unused path variable.
* include/grub/ieee1275/ieee1275.h (grub_ieee1275_flag): New enum values
GRUB_IEEE1275_FLAG_NO_OFNET_SUFFIX and
GRUB_IEEE1275_FLAG_VIRT_TO_REAL_BROKEN.
* grub-core/net/drivers/efi/efinet.c (grub_efinet_findcards): Use
txbufsize.
* grub-core/kern/ieee1275/cmain.c (grub_ieee1275_find_options): Use
compatible property to check for macs. Set
GRUB_IEEE1275_FLAG_NO_OFNET_SUFFIX and
GRUB_IEEE1275_FLAG_VIRT_TO_REAL_BROKEN on macs.
* grub-core/net/drivers/ieee1275/ofnet.c (card_open): Don't add suffix
if GRUB_IEEE1275_FLAG_NO_OFNET_SUFFIX is set.
(send_card_buffer): Use txbuf.
(grub_ofnet_findcards): Allocate txbuf. Simplify code flow and move
nested function out of the parent while on it.
* include/grub/net.h (grub_net_card_driver): Allow driver to modify
card. All users updated.
(grub_net_card): New members txbuf, rcvbuf, rcvbufsize and txbusy.
* grub-core/net/drivers/efi/efinet.c (send_card_buffer): Reuse buffer.
(get_card_packet): Likewise.
(grub_efinet_findcards): Init new fields.
with DMA.
* grub-core/commands/boot.c (grub_loader_noreturn): Rename to ...
(grub_loader_flags): ... this. All users updated.
(grub_loader_boot): Check for GRUB_LOADER_FLAG_NORETURN.
* grub-core/loader/i386/pc/pxechainloader.c (grub_cmd_pxechain): Mark
loader as GRUB_LOADER_FLAG_PXE_NOT_UNLOAD.
* grub-core/net/drivers/i386/pc/pxe.c (grub_pxe_shutdown): New
function.
(grub_pxe_restore): Likewise.
(fini_hnd): New var.
(GRUB_MOD_INIT): Register shutdown hook.
(GRUB_MOD_FINI): Shutdown and unregister shutdown hook.
* include/grub/loader.h (GRUB_LOADER_FLAG_NORETURN): New const.
(GRUB_LOADER_FLAG_PXE_NOT_UNLOAD): Likewise.
(grub_loader_set): Rename second argument to flags.
* grub-core/loader/i386/pc/pxechainloader.c: New file.
* grub-core/net/drivers/i386/pc/pxe.c (grub_pxe_get_cached): New
function.
(grub_pc_net_config_real): Use grub_pxe_get_cached.
* include/grub/i386/pc/pxe.h (grub_pxe_get_cached): New proto.
