similar to: [PATCH] Unification of ext_(write/read)_adv

Merge btrfs_read_adv and xfs_read_adv into a single generic function ext_read_adv and split ext_write_adv_offset out of ext_write_adv. Use those new functions in rewrite_boot_image and btrfs_install_file where it is actually hardcoded.

Hi, looking at ext_read_adv code (extlinux/main.c) static int ext_read_adv(const char *path, int devfd, const char **namep) { int err; const char *name; if (fs_type == BTRFS) { /* btrfs "ldlinux.sys" is in 64k blank area */ return btrfs_read_adv(devfd); } else if (fs_type == XFS) { /* XFS "ldlinux.sys" is in the first 2048 bytes of

This is part of some patches to support sectors > 512. Currently I'm able to boot a Ubuntu kernel but seems that mboot is not working for some reason. This patch try to fix ADV size problem.

Hello syslinux, Merry Christmas! These patches will make extlinux work with umounted ext2/3/4 filesystem, for example: $ extlinux -i /dev/sdXN or $ extlinux -i file_block Also it can work with something like: $ extlinux /dev/sdXN --reset-adv or $ extlinux file_block --reset-adv We don't use a new option (I planed to use "-d" but it is already in use), it will check whether the

Hello, Happy New Year! These patches make syslinux/linux support ext2/3/4, and it doesn't require the root privilege, I'd like to add a separate e2fs/syslinux, if that is more appropriate, it should be easy to do that. I put these patches on github so that you can easily get them in case you'd like to test them. (The repo's name is sys_tmp, which avoids confusing others, I will

It's needed to enumerate both UFS1/2 since they have different magic numbers and super block offsets. Besides, UFS2 can be installed in the 0-64k range like BTRFS, whereas UFS1 can't.

It's needed to enumerate both UFS1/2 since they have different magic numbers and super block offsets. Besides, UFS2 can be installed in the 0-64k range like BTRFS, whereas UFS1 can't.

From: Raphael S. Carvalho <raphael.scarv at gmail.com> v2: Extract ADV_SIZE automatically from libinstaller/setadv.h. Calc the size of ldlinux.sys from ldlinux.bin, and check if it exceeds the limit. ldlinux.sys must fit between the bootsector and two copies of ADV whose size may vary. Thus, the size of ldlinux.sys can be at most: 65536 - 2 * ADV_SIZE - 512 (limit). Certain file systems

Calc the size of ldlinux.sys from ldlinux.bin, and check if it exceeds the limit. ldlinux.sys must fit between the bootsector and two copies of ADV whose size may vary. Thus, the size of ldlinux.sys (limit) can be at most: 65536 - 2 * ADV_SIZE - 512. Certain file systems (such as BTRFS and UFS2) will rely on ldlinux.sys being installed on the 0-64k range, thus it can't exceed the limit,

Matt, ADV_SIZE is currently a constant value, but it may change in the future. So it would need some care. Regards, Raphael S. Carvalho

Add install_file_to_device() to support unmounted ext2, ext3 and ext4 filesystem. Usage: $ extlinux -i /dev/sdXN or $ extlinux -i file_block We don't need any new options, it will check whether the target is a directory or device and decide what to do, it would stop and error if the device is mounted. More info: * It will use libext2fs to read and write the file. * It will be used when the

This set of patches add some support for sector size >512. Currently it fixes extlinux, MBR for GPT and ext partitions. Other code is unaffected. This set of patches has been tested on a read Dell machine running a beta firmware.

This pull request contains the XFS filesystem driver for Syslinux. Due to historical reasons (SGI IRIX's design of disk layouts), the first sector in the primary AG on XFS filesystems contains the superblock, which is a problem with BIOSes, since VBRs must be loaded up from the first sector of the active partition. Thus, we needed to handle this issue by putting the Syslinux bootsector
