libinstaller: introduce syslxrw library

2015-11-11T00:14:30+00:00

Due to size constraints on DOS systems, do not include whole syslxcom
into DOS-based installer for using xpread() and xpwrite() functions,
instead make them part of another separate library and include it only.

libinstaller: Explicit failure if path isn't writable

2015-09-08T18:30:47+00:00

As per bug #4, we should report a clear failure if the target path is
not writable.

The current code was catching the fact the file was not writable
but it didn't wrote an explicit message and even more confusing, was
trying to process the file descriptor leading to a creepy "Bad file
descriptor" error message.

This patch does return EACCES to avoid process the file description.
It also print an explicit message saying a particular file isn't
writable which generates a fatal error.

A typical output looks like :
	[root@host]: extlinux --once=plop /boot
	/boot is device /dev/sda
	Cannot open file '/boot/ldlinux.sys' in read/write mode !
	Fatal error, exiting.

define _DEFAULT_SOURCE for glibc-2.20

2014-09-29T15:49:32+00:00

_BSD_SOURCE was deprecated in favour of _DEFAULT_SOURCE since glibc
2.20[1]. To avoid build warning on glibc2.20, _DEFAULT_SOURCE should
also be defined.

installer: Add UFS1/2 support for Extlinux installer

2014-06-02T21:02:36+00:00

It's needed to enumerate both UFS1 and UFS2 as they have different magic numbers
and super block offsets.

Neither UFS1 nor UFS2 move files around, therefore, ldlinux.sys can be
installed as a regular file.

installer: Add sparse address space annotations to the syslinux image

2014-01-18T00:55:34+00:00

Add sparse address space annotations for the syslinux boot image, to
make it easier to catch errors that break the DOS installer build
again.  Use "make CC=cgcc" to run sparse.

dos: We cannot use memset() for a far object, introduce memset_sl()

2014-01-16T18:56:29+00:00

We started using memset() on the extents buffer in ldlinux.sys, which
doesn't reside in the main segment, which worked on all the installer
platforms except DOS.  Fix DOS by introducing memset_sl() for this
case.

dos: obtain the executable pathname, cleanups

2013-01-17T17:34:59+00:00

DOS actually does provide the fully qualified pathname to the
executable, which would be useful to make ldlinux.c32 data rather than
live inside the executable itself -- it has gotten too large.

Also, move some DOS internals -- inline functions only used inside the
dos directory -- out of libinstaller.
