From Ilguiz Latypov:
* configure.in: Fix a syntax error in a sed script.
* stage2/bios.c (get_diskinfo): PhoenixBIOS 4.0 Revision 6.0
for ZF Micro might understand the greater buffer size for the
"get drive parameters" int 0x13 call in its own way.
Supposedly the BIOS assumes even bigger space is available and
thus corrupts the stack. This is why we specify the exactly
necessary size of 0x42 bytes.
From Steven Dick <ssd.gnu@mmae.ucf.edu>:
* stage2/pc_slice.h (PC_SLICE_TYPE_DELL_UTIL): New macro.
(IS_PC_SLICE_TYPE_FAT): Recognize PC_SLIDE_TYPE_DELL_UTIL as
well.
From H.J. Lu <hjl@gnu.org>:
* stage2/disk_io.c (part_start): Use unsigned long to support
large disks.
(part_length): Likewise.
* stage2/shared.h (part_start): Likewise.
(part_length): Likewise.
Add a workaround for buggy BIOSes which don't pass boot drive
correctly. The idea is that GRUB forces the fixed disk flag
when booted from a hard disk. When BIOS loads GRUB directly,
the boot drive must be either of 0x00 and 0x80, so this should
work, if those BIOSes always pass zero to %dl. AFAIK, this
assumption is always correct.
* stage2/builtins.c (install_func): Store the fixed disk flag of
the destination drive in BOOT_DRIVE_MASK in Stage 1.
* stage1/stage1.h (STAGE1_BOOT_DRIVE_MASK): New macro.
* stage1/stage1.S (boot_drive_mask): New variable. It is or'ed
to %dl.
* stage2/char_io.c (init_page): Change the software name from
"GRUB" to "GNU GRUB". This was inaccurate. Reported by Ciaran
O'Riordan <coriordan@compsoc.com>.
Change the terminal structure a bit, to turn the cursor state
explicitly. Suggested by Pavel Roskin.
* stage2/term.h (struct term_entry): Remove the member
`nocursor' and add `setcursor'.
[!STAGE1_5] (console_setcursor): New prototype.
[SUPPORT_HERCULES] (hercules_setcursor): Likewise.
[!STAGE1_5] (console_nocursor): Removed.
[SUPPORT_HERCULES] (hercules_nocursor): Likewise.
* stage2/stage2.c (run_menu): Call setcursor instead of
nocursor.
Call setcursor with 1 before starting a boot entry.
* stage2/shared.h (nocursor): Removed.
(setcursor): New prototype.
* stage2/hercules.c (herc_cursor_state): New variable.
(herc_turn_cursor): Removed.
(hercules_nocursor): Likewise.
(hercules_setcursor): New function.
* stage2/char_io.c (get_cmdline): Turn on the cursor at the
beginning, and restore it before returning.
(nocursor): Removed.
(setcursor): New function.
* stage2/asm.S (console_cursor_state): New variable.
(console_cursor_shape): Likewise.
(console_setcursor): New function.
(console_nocursor): Removed.
* grub/asmstub.c (console_setcursor): New function.
(hercules_setcursor): Likewise.
(console_nocursor): Removed.
(hercules_nocursor): Likewise.
From Alexander Langer <alex@big.endian.de>:
* stage2/freebsd.h (RB_GDB): New macro.
(RB_MUTE): Likewise.
(RB_MULTIPLE): Likewise.
* stage2/boot.c (bsd_boot): Set the bits of RB_MULTIPLE, RB_GDB
and RB_MUTE when "-D", "-g" and "-m" are specified,
respectively.
* stage2/disk_io.c (rawread): Make sure that SECTOR is valid.
If not, set ERRNUM to ERR_GEOM and return zero. This check is
critical when a partition table is corrupted.
* stage2/asm.S (console_cls): Write spaces to the entire screen
instead of getting/setting the video mode, because this flickers
the screen and is quite annoying, if using a LCD.
* grub/asmstub.c (console_translate_key): Deal with KEY_PPAGE
and KEY_NPAGE.
* stage2/serial.c (serial_translate_key_sequence): Added two new
codes for Page Up and Page Down.
* stage2/asm.S (translation_table): Added entries for KEY_PPAGE
and KEY_NPAGE.
* stage2/stage2.c (run_menu): Deal with Page Up and Page Down.
Also recognize the right key for the selection of a boot entry.
Suggested by Adam Lackorzynski <adam@os.inf.tu-dresden.de>.
* stage2/asm.S (gateA20): Output a dummy command (0xff), as a
workaround for USB keyboard hanging problem. Suggested by
Hidetoshi Nishimaki <nishimaki@mxs.nes.nec.co.jp>.
* configure.in (falign_loop_flag): New variable. Set to if GCC
supports `-falign-*'. If true, use `-falign-jumps',
`-falign-loops' and `-falign-functions' instead of
`-malign-jumps', `-malign-loops' and `-malign-functions',
because `-malign-*' are obsolete in GCC 3.x. Reported by Jeremy
Katz.
* stage2/boot.c (load_image): Rewrite the Linux booting support
radically. Now it should work even on a machine having, say,
only 128KB, theoretically. Of course, GRUB itself doesn't work
on such a system, though.
(load_initrd): Initialize LH based on CUR_ADDR, because the
location becomes dynamic.
* stage2/shared.h (LINUX_MAX_SETUP_SECTS): Set to 64.
(LINUX_HEAP_END_OFFSET): Set to (0x9000 - 0x200).
(LINUX_STAGING_AREA): Removed.
(LINUX_SETUP): Likewise.
(LINUX_KERNEL): Likewise.
(LINUX_KERNEL_MAXLEN): Likewise.
(LINUX_SETUP_SEG): Likewise.
(LINUX_INIT_SEG): Likewise.
(LINUX_SETUP_STACK): Set to 0x9000.
(LINUX_BZIMAGE_ADDR): New macro.
(LINUX_ZIMAGE_ADDR): Likewise.
(LINUX_OLD_REAL_MODE_ADDR): Likewise.
(CL_MY_LOCATION): Removed.
(CL_MY_END_ADDR): Likewise.
(CL_BASE_ADDR): Likewise.
(CL_MAGIC): Renamed to ...
(LINUX_CL_MAGIC): ... this.
(LINUX_CL_OFFSET): New macro.
(LINUX_CL_END_OFFSET): Likewise.
(LINUX_SETUP_MOVE_SIZE): Likewise.
(struct linux_kernel_header): Change the type of the member
"cmd_line_ptr" to char *.
(linux_data_tmp_addr): Declared.
(linux_data_real_addr): Likewise.
* stage2/asm.S [!STAGE1_5] (linux_data_tmp_addr): New variable.
[!STAGE1_5] (linux_data_real_addr): Likewise.
[!STAGE1_5] (big_linux_boot): Copy the real mode part from
LINUX_DATA_TMP_ADDR to LINUX_DATA_REAL_ADDR.
* grub/asmstub.c (linux_data_tmp_addr): New variable.
(linux_data_real_addr): Likewise.
From Mark Kettenis <kettenis@chello.nl>:
* stage2/boot.c (load_image): Recognize newer FreeBSD kernels.
* stage2/i386-elf.h (EI_OSABI): New macro.
(EI_ABIVERSION): Likewise.
(ELFOSABI_FREEBSD): Likewise.
(EI_PAD): Set to 9.
* stage2/shared.h (boot_part_offset): Removed.
* stage2/disk_io.c (set_bootdev): Copy the partition information
here. Now this function can call rawread, so it can fail.
(boot_part_offset): Removed.
* stage2/builtins.c (boot_func): Don't copy the partition
information here.
(real_root_func): Check ERRNUM after calling set_bootdev.
* stage2/serial.c [!GRUB_UTIL] (inb): Added a delay into this
function itself.
[!GRUB_UTIL] (outb): Likewise.
[!GRUB_UTIL] (serial_hw_put): Increase the timeout value, and
don't call serial_hw_delay explicitly any longer.
(fill_input_buf): Increase the maximum number of retries, reset
the counter to zero after getting a valid character, and don't
call serial_hw_delay explicitly any longer.
* stage2/builtins.c [SUPPORT_SERIAL || SUPPORT_HERCULES]
(terminal_func): Set CURRENT_TERM to each of selected terminals
before calling grub_printf, and restore CURRENT_TERM after it.
Reported by Ilguiz Latypov.
Prepend a carriage return to the prompting message, because it
is ugly that the same messages fulfill the whole screen.
* stage2/disk_io.c [SUPPORT_NETBOOT] (GRUB): Defined.
[SUPPORT_NETBOOT]: Include etherboot.h.
[!STAGE1_5] (print_completions) [SUPPORT_NETBOOT]: When
completing a disk name, if NETWORK_READY is true, add "nd" as a
completion.
* netboot/main.c (ifconfig): If GW is specified, clear out the
ARP entry for the gateway. If SVR is specified, clear out the
ARP entry for the server. Reported by Uwe Dannowski
<ud3@ira.uka.de>.
* util/grub-md5-crypt.in: Prompt to retype a password, and check
if the passwords matches. Suggested by Matt Perry
<matt@primefactor.com>.
Also, don't use Perl any longer, because *BSD's sh and GNU
support ``read -r'', and GRUB doesn't support any other
operating system anyway.
* stage2/builtins.c (boot_func): Load the boot partition
information, only if the address of the boot partition entry is
set appropriately.
(real_root_func): If ATTEMPT_MOUNT is false, call open_partition
and if successful, call set_bootdev, to set the offset of the
boot partition and the address of the boot paetition entry.
IF ATTEMPT_MOUNT is false, don't set BOOTDEV. The BSD evil hack
is useless with the command "rootnoverify" anyway.
* stage2/disk_io.c (boot_part_addr): Initialized with zero
explicitly, to emphasize that it is invalid.
Define the behavior of the boot loader when the load end address
and the bss end address are zero in the Multiboot Specification,
and add the support into GRUB. I've modified a patch from Yuri
Zaporogets <yuriz@ukr.net>.
* stage2/boot.c (load_image): In the case of Multiboot a.out
kludge, set the load end address to the load address plus the
size of the OS image file, if it is zero. Similarly, set the bss
end address to the load end address, if it is zero.
* util/mbchk.c (check_multiboot): Don't check if the load
address is greater than or equal to the load end address, if the
load end address is zero. Don't check if the load end address is
greater than the bss end address, if the bss end address is
zero. And, don't check if the load end address is less than or
equal to the entry address, if the load end address is zero.
* docs/multiboot.texi (The address fields of Multiboot header):
Added descriptions about the behavior of the boot loader when
LOAD_END_ADDR is zero and BSS_END_ADDR is zero.
* stage2/builtins.c (boot_func): If DEBUG is true, print
BOOT_DRIVE and BOOT_PART_OFFSET.
Don't set ERRNUM after rawread failed, because rawread should
set ERRNUM itself.
* lib/device.c (read_device_map): Show an error message and exit
abnormally, if MAP[DRIVE] has already been filled.
* util/grub-install.in: If there is any dulicated entry, print
an error message and exit abnormally.
* netboot/etherboot.h (ETH_MAX_MTU): Because some DHCP/BOOTP
servers don't treat the maximum length the same as Etherboot,
subtract the size of an IP header and that of an UDP header.
From Jean-Jacques Michel <jjmichel@linbox.com>:
* stage2/boot.c (load_image): For Linux, check if DATA_LEN is
greater than MULTIBOOT_SEARCH. If that's true, read the rest
after copying data already read in BUFFER.
* stage2/boot.c (load_image): For Linux, don't check if the
length of protected mode code is greater than or equal to the
expected length minus 16. Instead, just check if no error
occurred. That was problematic, because memdisk has no protected
mode code. Also, I don't see what the magic number 16 was for.
* stage2/builtins.c [GRUB_UTIL] (dump_func): New function.
[GRUB_UTIL] (builtin_dump): New variable.
(builtin_table) [GRUB_UTIL]: Added a pointer to BUILTIN_DUMP.
* util/grub-install.in: Make sure that GRUB reads the same
images as the host operating system by comparing the result of
running the command "dump" with the contents of the OS file.
* docs/grub.texi (General commands): Added ``pager'' into the
menu.
(pager): New subsection.
(terminal): Added a description about the option
``--lines=LINES''.
* configure.in (AC_INIT_AUTOMAKE): Set the version number to
0.92.
* stage2/boot.c (linux_mem_size): New variable.
(load_image): Check a mem= option and set LINUX_MEM_SIZE to the
specified memory size, if any. Otherwise, to zero. When an
overflow is detected, use LINUX_INITRD_MAX_ADDRESS instead.
(load_initrd): If LINUX_MEM_SIZE is non-zero, use it instead of
the actual memory size.
* stage2/char_io.c (safe_parse_maxint): Use ERR_NUMBER_OVERFLOW
instead of ERR_NUMBER_PARSING, when an overflow occurs.
* stage2/common.c [!STAGE1_5] (err_list): Added
ERR_NUMBER_OVERFLOW.
* stage2/shared.h (ERR_NUMBER_OVERFLOW): New constant.
* stage2/stage2.c (run_menu): Call cls outside the loop to run
scripts.
* stage2/cmdline.c (run_script): Prompt a user's intervention,
only when FALLBACK_ENTRY is negative.
* grub/main.c (OPT_NO_PAGER): New macro.
(longopts): Added an entry for "--no-pager".
(usage): Added a description about "--no-pager".
(main): In case of OPT_NO_PAGER, set USE_PAGER to zero. The same
thing is done with OPT_BATCH, because the pager is just harmful
in batch mode.
An internal pager is implemented.
* stage2/builtins.c (pager_func): New function.
(builtin_pager): New variable.
(terminal_func): New option, "--lines=LINES" is added. If this
option is specified, set MAX_LINES to the value. Otherwise, set
MAX_LINES to 24.
(vbeprobe_func): Remove the pager code specific to this
function.
(builtin_table): Added a pointer to BUILTIN_PAGER.
* stage2/char_io.c (max_lines) [!STAGE1_5]: New variable.
(count_lines) [!STAGE1_5]: Likewise.
(use_pager) [!STAGE1_5]: Likewise.
(grub_putchar) [!STAGE1_5]: if C is a newline and COUNT_LINES is
not -1, count up the number of lines. If it exceeds the maximum
number of lines minus 2, show a message and wait for input of
return key. "minus 2" is to reserve space for the message
printed by this internal pager.
* stage2/cmdline.c (enter_cmdline): If USE_PAGER is true, set
COUNT_LINES to zero, before running a command, and reset
COUNT_LINES to -1 after that.
* stage2/shared.h (max_lines) [!STAGE1_5]: Declared.
(count_lines) [!STAGE1_5]: Likewise.
(use_pager) [!STAGE1_5]: Likewise.
* stage2/fsys_jfs.c (jfs_read) [STAGE1_5]: Set and reset
DISK_READ_FUNC even in Stage 1.5.
* stage2/fsys_xfs.c (xfs_read) [STAGE1_5]: Likewise.
* stage2/stage1_5.c (saved_sector): Initialized with -1.
(cmain): Check if SAVED_SECTOR was set appropriately after
reading the second sector of Stage 2. If SAVED_SECTOR is not
set (i.e. it is equal to -1), print an error and stop.
