* extlinux: use sysfs to find the device node if need beH. Peter Anvin2012-02-081-10/+66
| | | | | | | | If neither /proc/mounts nor /etc/mtab contains a functional pointer to the device node for the installer, try to see if we can find the device node by looking for a symlink in /sys/dev/block. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

| | | | | | | Remove some dead code in the installer, which caused build error with gcc 4.6 and -Werror. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
* btrfs: Correctly determine the installation subvolumeYi Yang2011-07-282-32/+376
| | | | | | | There are multiple ways to set up subvolumes in btrfs. Use a general determination method which works for all schemes. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
* extlinux: remove wrong use of strstr()syslinux-4.05-pre4Paulo Alcantara2011-07-051-3/+1
| | | | | | | | strstr() is only used for zero-terminated strings, so OEM Name is not guaranteed to be zero-terminated. Instead, use fat_check_sb_fields() to sanity check FAT superblock. Signed-off-by: Paulo Alcantara <pcacjr@gmail.com>

* Add "make strip" targetH. Peter Anvin2011-05-091-0/+3
| | | | | | | | Add a "make strip" target, to make doing the official build easier. We want the official build to have stripped binaries for size reasons, so do it right and make it an actual build target. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* Remove -s for host binariesH. Peter Anvin2011-05-091-1/+1
| | | | | | | | Remove -s for host binaries; current practice is to let the distro packaging systems do that themselves. For the official binaries, we should probably strip them, but via an external tool. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the MCONFIG files into a mk/ directory and give them more descriptive names. This is purely a cosmetic change to make the 'include' directives a bit more coherent by making it obvious exactly which MCONFIG file we're including. For example, in com32/lua/src/Makefile we exchange the line, include ../../MCONFIG for the much more comprehensible, include $(MAKEDIR)/com32.mk Signed-off-by: Matt Fleming <matt.fleming@linux.intel.com>

* extlinux: try to get the disk offset from sysfsH. Peter Anvin2010-08-131-5/+38
| | | | | | | | | | | It is possible(?) that HDIO_GETGEO can't return the full offset, and in either case it is too small -- only 32 bits on 32-bit platforms. Thus query sysfs for the real value, if available. sysfs also contains information for slave devices -- this is going to really matter for the md/lvm issues. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
* extlinux, linux: Ignore --force in these installerssyslinux-4.02-pre4Shao Miller2010-07-191-1/+1

* libinstaller: Add --mbr, --active, and --force optionsShao Miller2010-07-031-1/+1
| | | | | | | | | | | | | | In order to consolidate the installer option-parsing system, we add the --mbr (-m), --active (-a), and --force (-f) options from the DOS, Win32, and mtools installers to libinstaller. Since the -m and -a options are not currently valid for the Linux 'syslinux' and 'extlinux' installers, we add error messages to both of these. The -f option is allowed but does nothing for them.

* 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. The glibc documentation states that *BSD sets the pointer to NULL, but instead of following that, the glibc people put warn_unused_result on asprintf. Sigh. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* extlinux: set bsHidden for loop devicesH. Peter Anvin2010-06-261-5/+8

* extlinux: modify the layout for btrfsH. Peter Anvin2010-06-251-9/+13
| | | | | | | | | Put the btrfs boot code right after the boot sector (they are really one image anyway). Align the ADV with the end of the boot region, so we can locate it for modification as necessary, and the offset don't end up shifting with different boot image sizes. Signed-off-by: H.

* Reduce sector 1 space pressure; further merge installer codesyslinux-4.00-pre52H. Peter Anvin2010-06-201-57/+70
| | | | | | | | | | Reduce sector 1 space pressure by moving objects that aren't needed by Sector 1 proper into an "extended patch area". While we're mucking with the installer code, make the syslxint and extlinux installer code even more similar. It should now be pretty straightforward to outright merge the code. Signed-off-by: H.

* Switch to 64-bit sector pointers everywhereH. Peter Anvin2010-06-152-9/+71
| | | | | | | | | | | | Switch to consistent use of 64-bit sector pointers; this should enable booting even for individual *partitions* larger than 2 TB. In order to not slow down the boot too much, switch the initial load from an enumeration to an extent map. This means the table gets larger (since we have to assume the worst case), but it simplifies the Sector 1 code (since we can push all the hard stuff into the installer), and will speed up booting in the general case. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
* Implement !GPT protocol in Syslinux core; handle offset > 2 TBH. Peter Anvin2010-06-141-3/+4
| | | | | | | | | | | | | | | Implement the !GPT handover protocol in the Syslinux core, and handle partition offsets above 2 TB. We do not yet handle filesystem sizes above 2 TB, but that should be a reasonably straightforward extension at this time (need to switch to 8-byte block pointers). This finally meant moving getlinsec out of the boot sector, since it no longer fits. Instead have a very simple getonesec implementation in the boot sector. getlinsec still fits in Sector 1, although it doesn't leave space for very many block pointers. That's still better than adding yet another boot loader stage, however. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
