Bug ID: 16124
Summary: ld.so should allow to change argv[0]
Product: glibc
Version: 2.19
Status: NEW
Severity: enhancement
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: piotr.roszatycki at gmail dot com
CC: drepper.fsp at gmail dot com
Created attachment 7267
--> https://sourceware.org/bugzilla/attachment.cgi?id=7267&action=edit
--argv0 option for ld.so
Any program can be started via dynamic loader explicitly, ie.
/lib64/ld-linux-x86-64.so.2. Unfortunately, there is no possibility to change
argv[0]. It makes this loader not so useful as it might be.
It would be nice if ld.so had an additional option which would replace argv[0].

Changing argv[0] is lying about binary name, how this would be used?

As you have a patch for this next step is send it to libc-alpha.
You need to follow
https://sourceware.org/glibc/wiki/Contribution%20checklist
including changelog entries like
2008-12-12 John Doe <johndoe@some.email.address>
[BZ #9999]
* login/utmp_file.c (pututline_file): Replace call to 'dup()'
with libc internal symbol '__dup()' to avoid access through
the PLT.
* manual/install.texi: Minimum version updated.
* INSTALL: Regenerated.
