description: "Bug summary: RELRO is not read-only on PowerLE\nBugzilla link: https://bugzilla.redhat.com/show_bug.cgi?id=1174826\n\
|
|
\n/* \
|
|
\ \n * Test to exercise PIE and RELRO provided by Roland McGrath <roland@redhat.com>.\n\
|
|
\ * \
|
|
\ \n * Description: \
|
|
\ \n * Simple test for RELRO, which happens to be a PIE too,\
|
|
\ but that's only \n * because this kind of example has to be in PIC\
|
|
\ code to make RELRO relevant, \n * and PIE makes it simpler to write a standalone\
|
|
\ one-file test than writing \n * a DSO. \
|
|
\ \n * \
|
|
\ \n * The \"const\" makes \"\
|
|
foo\" .rodata material, and the init to an external symbol\n * reference makes\
|
|
\ it require a data relocation. Enabling -z relro for this \n * link puts\
|
|
\ that .rodata into a RELRO area. This program will crash because \n * the\
|
|
\ page containing \"foo\" has been made read-only when \"main\" runs. \
|
|
\ \n * Without RELRO, it would let you modify \"foo\" even though it's supposed\
|
|
\ to \n * be const. \
|
|
\ \n * \
|
|
\ \n * Test with RELRO should fail: \
|
|
\ \n * $ gcc -pie -fPIE -g -Wl,-z,relro -o relro\
|
|
\ relro.c \n * $ ./relro \
|
|
\ \n * Segmentation fault (core\
|
|
\ dumped) \n * \
|
|
\ \n * Test without\
|
|
\ RELRO should pass: \n * $\
|
|
\ gcc -pie -fPIE -g -Wl,-z,norelro -o no-relro relro.c \
|
|
\ \n * $ ./no-relro \
|
|
\ \n * \
|
|
\ \n**/\n\n\n"
