[openFATE 312460] port issetugid() syscall to linux
Feature changed by: Jan Engelhardt (jengelh)
Feature #312460, revision 2
Title: port issetugid() syscall to linux

openSUSE Distribution: Unconfirmed
Priority
Requester: Important

Requested by: Ludwig Nussel (lnussel)
Partner organization: openSUSE.org

Description:
BSD has a issetugid() syscall that allows programs and libraries to
reliably determine whether they were started in a setuid context:
http://www.manpagez.com/man/2/issetugid/
This or a similar syscall would be valuable on Linux too, especially in
the advent of fscaps where the traditional uid != euid check doesn't
work anymore.

+ Discussion:
+ #1: Jan Engelhardt (jengelh) (2011-06-06 13:16:18)
+ This should be brought to the linux-security@vger mailing list.
