similar to: [PATCH] chain.c: allocation fixes

This patch introduces extra functionality to chain.c, mainly with reference to BPB adjustments, but not only that. It expects 3 small patches I sent earlier (they are included for easy reference, patches 1-3/4). The changes introduced are: 1) file and boot sector use separate options to control load address and jump address (if applicable). Options are as described below: *

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

1) public index in gpt iterator should not skip empty partitions, e.g. if we have 1st and 3rd gpt entry used, we expect the numbers to be 1 and 3, not 1 and 2 (similary to how linux sees it e.g. /dev/sda1 and /dev/sda3). It's analogous to index / mbr_index fix. 2) free(ebr_part); in mbr iterator was not reachable. ebr iterator takes care of freeing itself and its parent. 3) in ebr iterator,

>From the earlier patches - that simple fix for indexes not counting non-data partitions in gpt and mbr cases. Patches don't touch any other parts of the code at this stage - bigger stuff later for disklib as we agreed - but this is potentially useful right now.

In add_disk(), don't send uevent to userspace when gen_uevent is true; also export the refactored function disk_gen_uevents for later use.

While playing with some less than usual configurations, I've got bitten few times by geometry settings in case of, usually, microsoft[ish] systems. First two examples, then the improvement idea. Example #1 My usb stick has zip-compatible geometry, which should work fine both in hdd and zip modes. It usually does, at least as far as syslinux and normal software is considered - excluding

Here is the patch for making syslinux enable opening partitions with fat filesystems (well, the architecture is in place to make it open other filesystems too). Usage is like this: #include <syslinux/io.h> #include <syslinux/partitions.h> #include <fs/fat/libfat.h> syslinux_devdesc dfd; struct libfat_filesystem* fs; diskinfo disk_info; char mbr[512]; static part_entry

This is a continuation to the library creation effort for syslinux. I added the necessary ops required to read partitions and sectors off the disk. I'm using it with my com32 module. I did change the interface for read_disk a bit, so it takes a disk_info argument. This way I can maintain multiple instances of read handlers, for example if I'm reading and comparing stuff from two different

Hi all, I use XP on my laptop PC, with 30 GB HD (single partition), and a 3.5" hard drive (not a stick), accessed through a USB encasing, partitioned as five logical drives. I have successfully set up syslinux to boot several Ubuntu versions from the primary USB hard drive partition, and no problems there. The problem is, I would like to have an entry in the menu, like "Boot from

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.

Fix breakage in the "hide" option support patch: - The code which initialized the global variable "dapa" was lost in commit 81c203f2, therefore EBIOS access did not work properly. Fixed by removing the global variable completely and moving all bounce buffer handling into read_sector() and write_sector(). - write_sector() copied data to the bounce buffer, but then

The race condition is noticed between disk_add() and disk attributes, on virtio-blk hotplug. Userspace listens to the KOBJ_ADD uevent generated in add_disk(). At that point we haven't created the serial attribute file, therefore depending on how fast udev reacts, the /dev/disk/by-id/ entry doesn't always get created. As pointed out by Christoph Hellwig in the specific fix [1], virtio-blk

First it strips /sysroot and then finds common prefix aligned on slashes. Next it produces ../ for each slash found in common prefix and concatenates them with the rest of resolved link.
