The sections that contain paths have been allocated a 4096 +byte section, which is the maximum path length in linux. This will allow the +relocating script to parse the ELF binary, detect the section and easily replace +the strings in a certain path. + +Upstream-Status: Inappropriate [SDK specific] + +Signed-off-by: Laurentiu Palcu <laurentiu.palcu@intel.com> +Signed-off-by: Khem Raj <raj.khem@gmail.com> +--- + elf/dl-cache.c | 4 ++++ + elf/dl-load.c | 4 ++-- + elf/interp.c | 2 +- + elf/ldconfig.c | 3 +++ + elf/rtld.c | 5 +++-- + iconv/gconv_conf.c | 2 +- + sysdeps/generic/dl-cache.h | 4 ---- + 7 files changed, 14 insertions(+), 10 deletions(-) + +diff --git a/elf/dl-cache.c b/elf/dl-cache.c +index 6ee5153ff9..37a5f701fa 100644 +--- a/elf/dl-cache.c ++++ b/elf/dl-cache.c +@@ -133,6 +133,10 @@ do \ + while (0) + + ++const char LD_SO_CACHE[4096] __attribute__ ((section (".ldsocache"))) = ++ SYSCONFDIR "/ld.so.cache"; ++ ++ + int + _dl_cache_libcmp (const char *p1, const char *p2) + { +diff --git a/elf/dl-load.c b/elf/dl-load.c +index 62e3eee478..6ddba73650 100644 +--- a/elf/dl-load.c ++++ b/elf/dl-load.c +@@ -109,8 +109,8 @@ static size_t max_capstrlen attribute_relro; + gen-trusted-dirs.awk. */ + #include "trusted-dirs.h" + +-static const char system_dirs[] = SYSTEM_DIRS; +-static const size_t system_dirs_len[] = ++static const char system_dirs[4096] __attribute__ ((section (".sysdirs"))) = SYSTEM_DIRS; ++volatile static const size_t system_dirs_len[] __attribute__ ((section (".sysdirslen"))) = + { + SYSTEM_DIRS_LEN + }; +diff --git a/elf/interp.c b/elf/interp.c +index 9cd50c7291..fc2f39d73c 100644 +--- a/elf/interp.c ++++ b/elf/interp.c +@@ -18,5 +18,5 @@ + + #include <runtime-linker.h> + +-const char __invoke_dynamic_linker__[] __attribute__ ((section (".interp"))) ++const char __invoke_dynamic_linker__[4096] __attribute__ ((section (".interp"))) + = RUNTIME_LINKER; +diff --git a/elf/ldconfig.c b/elf/ldconfig.c +index fbdd814edf..9f4d8d69b1 100644 +--- a/elf/ldconfig.c ++++ b/elf/ldconfig.c +@@ -168,6 +168,9 @@ static struct argp argp = + options, parse_opt, NULL, doc, NULL, more_help, NULL + }; + ++ ++extern const char LD_SO_CACHE[4096] __attribute__ ((section (".ldsocache"))); ++ + /* Check if string corresponds to an important hardware capability or + a platform. */ + static int +diff --git a/elf/rtld.c b/elf/rtld.c +index 453f56eb15..08e0c4c94b 100644 +--- a/elf/rtld.c ++++ b/elf/rtld.c +@@ -128,6 +128,7 @@ dso_name_valid_for_suid (const char *p) + } + return *p != '\0'; + } ++extern const char LD_SO_CACHE[4096] __attribute__ ((section (".ldsocache"))); + + /* LD_AUDIT variable contents.
