Subject: [PATCH] 51889: fix module loading problem with full RELRO
|
|
|
|
If full RELRO (relocation read-only, one of the security enhancement
|
|
methods for ELF-based systems) is used when building zsh (as in binary
|
|
packages of most Linuxes), loading a module (e.g. zsh/zftp) fails unless
|
|
all the modules it depends on are already loaded. With this patch the
|
|
necessary modules are automatically loaded.
|
