            Bug ID: 29498
           Summary: Is it expected that eu-strip strips .note.GNU-stack
           Product: elfutils
           Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: tools
          Assignee: unassigned at sourceware dot org
          Reporter: jpalus at fastmail dot com
                CC: elfutils-devel at sourceware dot org
  Target Milestone: ---

Accidentally we've started to strip crt*.o files produced by glibc and were
surprised by the fact that eu-strip gets rid of .note.GNU-stack section
resulting in incorrect linking.

$ gcc -c test.c -o test.o
$ readelf -S test.o|grep GNU-stack
  [ 5] .note.GNU-stack   PROGBITS         0000000000000000  00000074
$ eu-strip test.o
$ readelf -S test.o|grep GNU-stack
(empty)

I see following comment in strip.c:

> - special sections named ".comment" and ".note" are kept


https://sourceware.org/git/?p=3Delfutils.git;a=3Dblob;f=3Dsrc/strip.c;h=3D4=
52b12796dd3b7ff3a46d13a2bfb9aa0f5c93ac9;hb=3DHEAD#l1361

The question is whether observed behavior is expected or rather .note.GNU-s=
tack
should be kept?
