Change our ELF binary branding to something more acceptable to the Binutils maintainers. After we established our branding method of writing upto 8 characters of the OS name into the ELF header in the padding; the Binutils maintainers and/or SCO (as USL) decided that instead the ELF header should grow two new fields -- EI_OSABI and EI_ABIVERSION. Each of these are an 8-bit unsigned integer. SCO has assigned official values for the EI_OSABI field. In addition to this, the Binutils maintainers and NetBSD decided that a better ELF branding method was to include ABI information in a ".note" ELF section. With this set of changes, we will now create ELF binaries branded using both "official" methods. Due to the complexity of adding a section to a binary, binaries branded with ``brandelf'' will only brand using the EI_OSABI method. Also due to the complexity of pulling a section out of an ELF file vs. poking around in the ELF header, our image activator only looks at the EI_OSABI header field. Note that a new kernel can still properly load old binaries except for Linux static binaries branded in our old method. * * For a short period of time, ``ld'' will also brand ELF binaries * using our old method. This is so people can still use kernel.old * with a new world. This support will be removed before 5.0-RELEASE, * and may not last anywhere upto the actual release. My expiration * time for this is about 6mo. * 2000-04-18 02:39:26 +00:00			`# $FreeBSD$`

Utility to "brand" ELF binaries. Man page to come... For now use: <brandelf -t Linux linuxbin> to brand, and just <brandelf> to verify branding on a ELF file. FreeBSD native is set with <brandelf -t FreeBSD freebsdbin>. 1996-10-16 18:16:22 +00:00			`PROG= brandelf`
