Re: grub-fstest build issue in grub2-r2071 +
An update: I looked at the change between r2077 and r2104 and it looks
like the relevant code is util/hostdisk.c; I've attached a patch that
appears to fix the problem.

Hi Again,
Thanks, r2104 builds with --enable-grub-fstest now, but a new problem,
not present in r2101 has surfaced: the command grub-probe now aborts on
my system with xfs filesystems. Therefore, I cannot run grub-install
(even with --modules=xfs). With rev's 2101, 2087, 2077, 2071, and 2065
grub-probe ran without error. Here's my hd config:
#device mount-point fs type options dumpfsck
/dev/hda1 swapswapdefaults0 0
/dev/hda2 / xfs defaults1 1
and here's the output of grub-probe (r2104):
# grub-probe -v --target=fs --device /dev/hda2

Hi all,
I have built grub2-r2065 and it works nicely for me so far for linux
boots (love the graphics!!). However, beginning with r2071, I am unable
to build it with the --enable-grub-fstest option due to several
undefined refs:
It started in r2067.
To handle this (I'm now building r2101), I add normal/datetime to the
grub-fstest build specs,
Fixed in subversion. Thank you!

For example when building certain grub-* tools there is no way to get around the current redefinitions we get of LONG_MAX and friends.

Maybe this is not necessary nowadays, but my old lesson was to use test x$target_alias != x instead for portability. Well, != was not very portable, either, maybe. I believe both -n and != are found in Autoconf sources that are turned into configure scripts. Anyway, I'll use the syntax you want. Even if this looks obsolete, I think it is better to follow the chapter Limitations of Builtins in the autoconf manual: `test' (strings) Posix says that `test STRING' succeeds if STRING is not null, but this usage is not portable to traditional platforms like Solaris 10 `/bin/sh', which mishandle strings like `!' and `-n'. Posix also says that `test ! STRING', `test -n STRING' and `test -z STRING' work with any string, but many shells (such as Solaris, AIX 3.2, UNICOS 10.0.0.6, Digital Unix 4, etc.) get confused if STRING looks like an operator: $ test -n = test: argument expected $ test ! -n test: argument expected Similarly, Posix says that both `test STRING1 = STRING2' and `test STRING1 != STRING2' work for any pairs of strings, but in practice this is not true for troublesome strings that look like operators or parentheses, or that begin with `-'. It is best to protect such strings with a leading `X', e.g., `test XSTRING != X' rather than `test -n STRING' or `test ! STRING'.

+ (*argn) += 3;
I myself feel that these parentheses are redundant, but I don't know how
others think. For C programmers, it is well known that * has a very high
priority.
These parenthesis are necessary if doing sth like
(*argn)++
since ++ and += are logically and visually similar I prefer to put the
parenthesis
OK.
Getting tired, so I skip the same criticism from here.
Actually it would have been enough to say same applies further on in
patch
+ if (*argn + 1 argc !grub_strcmp (args[*argn], -s))
+ {
+ grub_file_t file;
+ file = grub_file_open (args[*argn + 1]);
+ update_val (file grub_file_size (file));
This is not very safe, because grub_file_size returns grub_off_t which is
a 64-bit unsigned int. By converting it into 32-bit signed int
implicitly, the result can be zero, even when the size is not zero. So it
is better to say explicitly, != 0.
BTW, I think you can simplify test_parse. For example, you write if (*argn +
2 argc ...) many times, but it should be possible to test this condition
only once per loop.

Kexec loading grub2
For a number of weird reasons, I would find the ability to kexec into grub2 from a running linux system useful. In looking at the current code out there, there seems to be two ways to make grub2 able to support this: 1) Add a 32-bit load segment to boot/i386/pc/lnxboot.S as described by http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=Documentation/x86/boot.txt (at the bottom) grub4dos (which is kexec'able) implements this in startup_32: @ http://svn.gna.org/viewcvs/grub4dos/trunk/stage2/dosstart.S?view=markup 2) Adjust the ELF images made by grub-mkimage (for coreboot) to be loaded by kexec-tools's ELF loader (or vice-versa). I figure this is the best route to go about adding kexec boot ability to grub2 since the BIOS-services-less kexec environment may be similar to coreboot's environment. Currently, loading this image: grub-mkelfimage --directory=/usr/lib/grub/i386-coreboot --prefix=/boot/grub --output=grub2.elf --memdisk=memdisk.cpio memdisk cpio #readelf -l grub2.elf Elf file type is EXEC (Executable file) Entry point 0x8200 There are 3 program headers, starting at offset 52 Program Headers: Type Offset VirtAddr PhysAddr FileSiz MemSiz Flg Align LOAD 0x94 0x8200 0x8200 0x06fd8 0x0e86c RWE 0x20 GNU_STACK 0x00706c 0x 0x 0x0 0x0 RWE 0x4 LOAD 0x00706c 0x00017000 0x00017000 0x73fb0 0x73fb0 RWE 0x4 #file -k grub2.elf grub2.elf: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), statically linked, stripped like so: (using latest git://git.kernel.org/pub/scm/linux/kernel/git/horms/kexec-tools.git) # kexec --type multiboot-x86 --load grub2.elf issues this error: Base address: 8200 is not page aligned The original kexec kernel patch maintainer had these things to say about that: https://lists.linux-foundation.org/pipermail/fastboot/2005-August/008743.html http://www.mail-archive.com/fastb...@lists.linux-foundation.org/msg00249.html I noticed this line in the grub2 src: ./conf/i386-coreboot.rmk:36:kernel_elf_LDFLAGS = $(COMMON_LDFLAGS) -Wl,-N,-S,-Ttext,0x8200,-Bstatic but I'm sure there's gonna be more involved than just changing that to 0x8000. kexec_test is an example of a kexec-loadable elf: (http://git.kernel.org/?p=linux/kernel/git/horms/kexec-tools.git;a=tree;f=kexec_test;hb=HEAD) #file -k kexec-tools.git/build/lib/kexec-tools/kexec_test kexec_test: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), statically linked, not stripped #readelf -l /tmp/kexec-tools/build/lib/kexec-tools/kexec Elf file type is EXEC (Executable file) Entry point 0x109c4 There are 2 program headers, starting at offset 52 Program Headers: Type Offset VirtAddr PhysAddr FileSiz MemSiz Flg Align LOAD 0x001000 0x0001 0x0001 0x00e40 0x00e40 R E 0x1000 LOAD 0x002000 0x00011000 0x00011000 0x0 0x0102c RW 0x1000 Section to Segment mapping: Segment Sections... 00 .text 01 .bss I don't have the know-how currently to implement either route but I may be able to learn with a little guidance.

You can make a minimal fbsd system in the mfsroot that is smart enough to init_chroot from a SMB/NFS netmount, or from a cloop file stored a CD or http-sever (cached to a tmpfs (ramdisk)). Mine also unionfs-mounts a tmpfs to what ever root that is used so you can make changes in ram and not on the source root mount. This is also what Frenzy does - http://frenzy.org.ua/eng/ I don't know if HeX unionfs-mounts or not - http://www.rawpacket.org/projects/hex Also, will it be advantageous to me? I find it useful for executing FreeBSD rescues and where I need to pkg_add tools that are not already on the rootfs. (FreeBSD installations contained within a UFS, UFS2 /or ZFS logical partition) I didn't think of it at first, but the mfsroot could also have all the smarts contained in it for mounting and init_chroot'ing a ZFS root. You still have to load grub and the kernel/mfsroot from a grub-supported fs, but I was very pleased to hear that phcoder is working on that! -joey ___ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel ___ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel

You can checkout the code via: svn co svn://svn.savannah.gnu.org/grub/trunk/grub2 Then use the autocompile.sh script that was posted earlier to make builds of grub2 or you can wait for the nightly autobuilder to be set-up and just download its results (from wherever they will be announced).

Maybe this is not necessary nowadays, but my old lesson was to use test x$target_alias != x instead for portability. Well, != was not very portable, either, maybe. I believe both -n and != are found in Autoconf sources that are turned into configure scripts. Anyway, I'll use the syntax you want. Even if this looks obsolete, I think it is better to follow the chapter Limitations of Builtins in the autoconf manual: Thanks. The Autoconf code I was referring to didn't involve any possibility of pathological arguments.
