* libinstaller: introduce syslxrw libraryPaulo Alcantara2015-11-105-65/+106
| | | | | | | | 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. Signed-off-by: Paulo Alcantara <pcacjr@zytor.com>
* libinstaller: Explicit failure if path isn't writableErwan Velu2015-09-081-1/+2
| | | | | | | | | | | | | | | | | | | | 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.

* installer: Add UFS1/2 support for Extlinux installerRaphael S. Carvalho2014-06-021-1/+3
| | | | | | | | | | | It's needed to enumerate both UFS1 and UFS2 as they have different magic numbers and super block offsets.

| | * EXTLINUX: Initial XFS filesystem supportPaulo Alcantara2012-07-211-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | XFS filesystems are divided into a number of equally sized chunks called Allocation Groups (AGs). Each AG can almost be thought of as an individual filesystem that maintains its own's space usage. Each AG has the following structure: - A super block describing the overall filesystem info - Free space management - Inode allocation and tracking So, 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 bootloaders that rely on BIOSes (that load VBRs which are located in the first sector of the partition). This patch adds support to the EXTLINUX installer to be able to install Syslinux in an XFS partition, but with a limitation (temporarily) of relying on the filesystem block size being 4+ KiB, otherwise there won't be enough space to store the Syslinux boot sector in the blank area around the 2048 to 4096 bytes of the primary AG/superblock.

A better solution is to write the object files to a per-firmware directory under a top-level object directory. The top-level object directory can be specified on the command-line with the O= variable, e.g. make O=/tmp/obj. If no top-level object directory is specified an 'obj' directory is created in the top-level of the Syslinux source repository. All the existing make targets continue to work as before, however now they apply to all firmware backends, e.g. 'make installer' will build the BIOS, 32-bit EFI and 64-bit EFI installers and place them under $(OBJ)/bios, $(OBJ)/efi32 and $(OBJ)/efi64 respectively. Note unlike every other bit of Syslinux, the gpxe objects are still kept in the src directory, e.g. gpxe/src, since gpxe is only required by the BIOS backend. It is possible to specify a make target for a specific firmware or list of firmware with the following syntax, make [firmware[,firmware]] [target[,target]] To clean the object directory for just the BIOS firmware type, 'make bios clean' To build both the 32-bit and 64-bit EFI installers type, 'make efi32 efi64 installer' Since the Syslinux make infrastructure is now more complex a new file doc/building.txt has been created to explain how to build Syslinux. The top-level Makefile now exports some make variables for use in module Makefiles, - topdir - the top-level source directory of the Syslinux repository, e.g. /usr/src/syslinux - objdir - the top-level object directory for the firmware backend currently being built, e.g. /obj/syslinux/bios - SRC - the source directory in the Syslinux repository for the module currently being built, e.g. /usr/src/syslinux/com32/libupload - OBJ - the object directory for the module currently being built, e.g. /obj/syslinux/bios/com32/libupload Since we're rewriting the Makefile infrastructure anyway it seemed like a good idea to add parallel support. By writing subdirectories as prequisites for make targets the objects in those subdirectories can be built in parallel. Signed-off-by: Matt Fleming <matt.fleming@intel.com>
