similar to: [PULL 0/8] MultiFS suppport for BIOS and EFI

Hello, the following patches should get multidisk access working. The syntax accepted is the following: (hdx,y)/path/to/file where x is the disk number and start at 0 and the y is the partition number starting at 1. So (hd0,1) is the first partition of the first disk. the other accepted syntax is using MBR's 32 bits disk signature so for example: (mbr:0x12345678,2)/foo/bar would address

This is a bit updated set of chain.c32 changes that simplifies a few things (and in partiter part), fixes few minor issues and adds a few new features. Details are in the following commits, below is the summary and pull details at the end. Shao - any chance to peek over them ? Most of those are relatively simple changes and well tested, though of course something might have slipped my attention.

1) code split and move Iterator related functionality is yanked from chain.c and moved to iterator.{c,h}. Both are moved to com32/chain and this way chain.c is ready for further splitting. Alternatively, partiter could be moved to com32/lib at any time in the future. It's potentially useful for other modules (e.g. if someone wanted to code partition dumper or editor). 2) Iterator updates

This small set fixes few bugs, improves gpt handling (under buggy conditions) and implements strict flag with more fine grained control which should fix issues with sanity checks against disk sizes. If this set is allright I'd want to do what I mentioned in older discussion with Ady - backport missing patches from 6.x to 5.x and 4.x so all versions have up to date chain version. Michal

From: Raphael S. Carvalho <raphael.scarv at gmail.com> This patch finishes the MultiFS support. init_multifs gets called in the main (startup) function of ldlinux.c32, so MultiFS will be initialized automatically. init_multifs calls enable_multifs (lives in the core) to hook get_fs_info. Subsequent accesses will callback the get_fs_info living in ldlinux.c32. Signed-off-by: Raphael S.

Previous version had some issues in case of error situations, among those: - backup gpt header was not read if reading of primary failed - alternating nature of lba_cur and lba_alt was ignored This patch fixes this and extends the gpt handling. The current behavior is: - try primary header; if unreadable or checksum fails (or sanity checks fail unless relax flag is set) - try secondary header

From: Raphael S. Carvalho <raphael.scarv at gmail.com> MULTIFS SYNTAX: (hd[disk number]:[partition number])/path/to/file The meaning of this_fs was changed to improve the flexibility of the support.

Check if fs_ops->readdir is available before calling it. At least PXELINUX doesn't implement it.

Hello Everyone Sometime ago there was some discussion about Syslinux multifs support. I've tested it for some time using qemu and it seems to be working. Lately I've started testing it with my real hardware and for some reason it doesn't work. I don't really know how to debug Syslinux (aside from using printf), so what I've succeeded to discover with is that the

Before proceeding with the MultiFS patchset, let's discuss the MultiFS syntax. It's currently as follows: (hd[disk number]:[partition number])/path/to/file Any objections? Regards, Raphael S. Carvalho
