--- Comment #2 from Mark Wielaard <mark at klomp dot org> --- (In reply to Fangrui Song from comment #1) > You can additionally link an object file with an artificial long symbol > name. Since that symbol is not used, you can change its .dynstr I think that is really fragile. The way Solaris does this (what I assume Ben, the original reporter, is after) is by introducing a new dynamic section entry that provides the padding that is still available. That way tools know where and how much space they can use for dynamic strings. We could introduce DT_GNU_STRPAD and suggest that linkers initially set it to 256 (and add that to DT_STRSZ) to make such manipulations easy and robust. Any tool manipulating the .dynstr segement can then use (and update) that when adding a new string.
