* Packed definition: workaround for mingw + gcc 4.7H. Peter Anvin2012-10-221-6/+17
| | | | | | | | | | | | __attribute__((packed)) does the wrong thing when in ms-struct mode; this breaks compiling on mingw-w64. Therefore force gcc struct mode when we use packed. This obsoletes checkin 7d9ee65 win: Add -mno-ms-bitfields Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>

* libinstaller: Avoid using <linux/ext2_fs.h>syslinux-4.06-pre3H. Peter Anvin2012-03-263-11/+886
| | | | | | | | | | | | | Don't use <linux/ext2_fs.h> if we can avoid it. The ioctl constants have been globalized and moved to <linux/fs.h>. Use a private copy of ext2_fs.h from e2fsprogs with the ioctl constants removed for the data structures. Do at least attempt backward compatibility for old kernel headers, but no real hope of proper operation there... Signed-off-by: H. Peter Anvin <hpa@zytor.com>

| | | | | | | | 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>

| | | | | | | | | | | | | | | | syslinux_already_installed function will be used in both extlinux and syslinux for checking if the boot sector has either the string "SYSLINUX" or "EXTLINUX" in the OEMID field. Signed-off-by: Paulo Alcantara <pcacjr@gmail.com>

* disk: put a magic at the end of the boot sectorH. Peter Anvin2011-01-251-2/+6
| | | | | | | | | Put a magic signature at the end of the boot sector, and a backpointer to the code that contains the pointer to the main code extent. This is useful for integrity-checking tools, and could help the installer in the future. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
* Fix missing option -s in libinstallersyslinux-4.03-pre3Arwin Vosselman2010-09-091-1/+1
| | | | | | | | In 'libinstaller/syslxopt.c' on line 71 the "s" (undercast) is missing in: const char short_options[] = "t:fid:UuzS:H:rvho:OM:ma"; Adding the 's' there seems to solve our problem.
* syslxopt: remove lengthy warning messageH. Peter Anvin2010-07-301-10/+0
| | | | | | | Remove a lengthy warning message which cause the actual command reference to overflow a 24-line screen. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* syslxopt: fix fatal warningsH. Peter Anvin2010-07-301-9/+12
| | | | | | | | | | | Fix fatal warnings in syslxopt.c partly due to legal but non-idiomatic use of switch(). Since the only purpose was to conditionalize single output statements, just do it explicitly. In addition, since they are conditional messages, there is no need to explain when they apply.

* dos: change the link procedure to use negative pointers below DGROUPH. Peter Anvin2010-07-191-3/+1
| | | | | | | | | Use negative pointer values below DGROUP, i.e. for the .payload segment. This makes it a lot easier to figure out if we are dealing with pointers that shouldn't come from where they do, since the DGROUP and .payload segments no longer overlap, and in fact are congruent.

* libinstaller: Add --mbr, --active, and --force optionsShao Miller2010-07-032-2/+20
| | | | | | | | | | | | | | 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. Signed-off-by: Shao Miller <shao.miller@yrdsb.edu.on.ca>
* installers: handle asprintf() correctlyH. Peter Anvin2010-07-021-6/+8
| | | | | | | | | | | | | 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.

* <linux/loop.h>: deal with really ancient Linux kernel headersH. Peter Anvin2010-06-271-0/+6

* Reduce sector 1 space pressure; further merge installer codesyslinux-4.00-pre52H. Peter Anvin2010-06-202-140/+99
| | | | | | | | | | 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 Anvin2010-06-155-63/+266
| | | | | | | | | | | | 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 Anvin2010-06-142-10/+11
| | | | | | | | | | | | | | | 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>
