Raw Normal View History

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. *

# $FreeBSD$
Quiet compiler warnings by making `WARNS 2' clean. Submitted by: Mike Barcroft <mike@q9media.com> Set maintainer to myself. This needs to stay in sync with what Buntils does, and it would be best to pass functionality changes thru me to make sure future plans are taken into account.

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>.
