H.J,
I think we are fragmenting with too many standards and mailing lists.
This
new discussion group and eventually the resulting standards, all might be
put under LSB http://refspecs.linuxfoundation.org/lsb.shtml
The Intro on LSB says:
http://refspecs.linuxfoundation.org/LSB_5.0.0/LSB-Core-generic/LSB-Core-generic/elfintro.html
And thats what this proposal is intended for.
And we can use the LSB mailing list
https://lists.linux-foundation.org/mailman/listinfo/lsb-discuss for all
discussions.
What do you think?
LSB lists extensions which have been implemented. But it isn't a spec
you can use to implement them. For example:
http://refspecs.linuxbase.org/LSB_3.1.0/LSB-Core-generic/LSB-Core-generic/progheader.html
lists PT_GNU_EH_FRAME, PT_GNU_STACK and PT_GNU_RELRO.
But it gives no details. Linux ABI group is the place where we propose
extensions before they get implemented.
How to implement, according to me, is design details of a particular
product. It also depends on the language used to develop the product.
Standards, in most cases, are not tied to a language and hence do not
enforce implementation details.
That is exactly what Linux ABI group tries to address. Please see
the Linux gABI extension draft at
https://github.com/hjl-tools/linux-abi/wiki/Linux-Extensions-to-gABI
It describes the conventions and constraints on the implementa-
tion of these extensions for interoperability between various tools.
Intel ABI allows abi for binary compatibility on intel machines - just
copy bins no need to target compile.
Linux ABI? linus already suggested this in even 1990's releases:
warning: do not share your kernel headers with applications, they might
abuse it and anyway software relying on it would break soon (be a waste
of time) when new releases released
i just noticed myself the BEST PROTECTION against the need of ABI: is a
kernel that has abi inside and offers fast exported features on "well
known unix interfaces" to what otherwise would make software "machine
dependant, fallible, and short lived"
