* extlinux: code cleanup and simplificationNicolas Cornu via Syslinux2015-11-251-58/+55
| | | | | | | | | | | 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.

* installer: Add UFS1/2 support for Extlinux installerRaphael S. Carvalho2014-06-021-9/+42
| | | | | | | | | | | It's needed to enumerate both UFS1 and UFS2 as they have different magic numbers and super block offsets.

* btrfs: Move ldlinux.sys to Boot Area BH. Peter Anvin2014-05-201-6/+9
| | | | | | | | | | ldlinux.sys is frequently too big to fit into Boot Area A (64K). Per a recent ruling by Chris Mason, we have a 768K Boot Area B at offset 256K, so use that to store ldlinux.sys. In theory we could split it up and make it slightly larger, however, ldlinux.sys is loaded below the 640K mark so it has to be smaller than that size anyway. Signed-off-by: H.

| * extlinux: Fix installation subdirectory patchingMatt Fleming2013-01-101-7/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit a126f17f663c ("EXTLINUX: Initial XFS filesystem support") broke the code that inserts the installation subdirectory into the Extended Patch Area (EPA). The EPA entry is used to set the initial working directory on boot. This caused boot failures for users that chose an install directory other than /boot/syslinux (technically, it failed for any path not in 'search_directories' in load_env32()) due to ldlinux.c32 failing to load because the initial working directory was not set correctly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Syslinux won't work on >4 KiB filesystem block sizes since there is no left space in MBR to determine where to install Syslinux bootsector. If one is trying to install Syslinux in a XFS partition with a filesystem block size different of 4 KiB, a proper error will be returned to the user informing that the current filesystem block size isn't supported by Syslinux.

| | * EXTLINUX: Initial XFS filesystem supportPaulo Alcantara2012-07-211-39/+184
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

This means that a pointer containing random data from the stack is passed to ext_write_adv(). Just delete the opt.reset_adv logic since modify_adv() handles that case anyway.

* | Add per-firmware object directory supportMatt Fleming2012-10-161-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that we have multiple firmware backends it no longer makes sense to write object files to the same directory as their source. 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>

* installers: handle asprintf() correctlyH. Peter Anvin2010-07-021-5/+6
| | | | | | | | | | | | | It appears that the glibc version of asprintf() is braindamaged, and doesn't set the target pointer to NULL in the event of an error (only returns -1). Therefore we need to check the return value. Just in case someone else made the *opposite* error, also check the pointer. Bleh.
