Import the #'clear-string API from GNU, use it in tls.c
src/ChangeLog addition:
2015-04-18 Aidan Kehoe <kehoea@parhasard.net>
* sequence.c (Fclear_string): New, API from GNU. Zero a string's
contents, making sure the text is not kept around even when the
string's data is reallocated because of a changed character
length.
* sequence.c (syms_of_sequence): Make it available to Lisp.
* lisp.h: Make it available to C code.
* tls.c (nss_pk11_password): Use it.
* tls.c (gnutls_pk11_password): Use it.
* tls.c (openssl_password): Use it.
tests/ChangeLog addition:
2015-04-18 Aidan Kehoe <kehoea@parhasard.net>
* automated/lisp-tests.el:
Test #'clear-string, just added. Unfortunately there's no way to
be certain from Lisp that the old password data has been erased
after realloc; it may be worth adding a test to tests.c, but
*we'll be reading memory we shouldn't be*, so that gives me pause.

The files of Emacs are written so as to have no initialized data that can ever need to be altered except at the first startup. This is so that those words can be dumped as sharable text. It is not possible to exercise such control over library files. So it is necessary to refrain from making their data areas shared. Therefore, this file is loaded following all the files of Emacs but before library files. As a result, the symbol my_edata indicates the point in data space between data coming from Emacs and data coming from libraries. */ #include <config.h> char my_edata[] = "End of Emacs initialized data"; /* Ensure there is enough slack in the .bss to pad with. */ #ifdef HEAP_IN_DATA #define BSS_PADDING 0x1000 #else #define BSS_PADDING 1 #endif char my_ebss [BSS_PADDING];
