Bug #: 14512
Summary: -z nodelete should be default for shared libraries
Product: binutils
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: ld
AssignedTo: unassig...@sourceware.org
ReportedBy: bug...@aerifal.cx
Classification: Unclassified
See glibc bug #14511:
http://sourceware.org/bugzilla/show_bug.cgi?id=14511
If this can't/won't be fixed at the dynamic linker level, it should be fixed in
binutils. Relying on every library, which might not even be intended for use
with dlopen but might get loaded implicitly as a dependency of a dlopened
library, is unsafe and unpractical; it leads to obscure crash bugs that may
only arise for certain configurations of the underlying dependencies of a
library. Since unloading a library is unsafe by default unless it was
explicitly designed to be unloadable, -z nodelete should be the default option
and -z delete should be needed to override it and specify that a .so being
generated is intended for use as an unloadable plugin.
