RELRO（ReLocation Read-Only）机制的提出就是为了解决延迟绑定的安全问题，它最初于2004年由Redhat的工程师Jakub Jelínek实现，它将符号重定向表设置为只读，或者在程序启动时就解析并绑定所有动态符号，从而避免GOT上的地址被篡改。如今，RELOR有两种形式：? Partial RELRO：一些段（包括.dynamic、.got等）在初始化后...
relocation against stdout in read-only section "relocation against stdout in read-only section" 是一个在编译和链接过程中可能出现的错误消息。它通常出现在尝试将代码或数据段标记为只读,但链接器(linker)在尝试解析符号引用时遇到了问题。 简单地说,当你尝试在一个只读(或受保护)的内存区域中写入数据时,就...
In partial RELRO, the non-PLT part of the GOT section (.got from readelf output) is read only but .got.plt is still writeable. Whereas in complete RELRO, the entire GOT (.got and .got.plt both) is marked as read-only. Both partial and full RELRO reorder the ELF internal data secti...
We develop a new system startup mechanism, to reduce the boot time by using selectively relocating read-only sections in NVRAM. We develop a model to determine the set of segments to be loaded into NVRAM given the maximum launch latency constraint and the physical latency of NVRAM. We ...
1. 解决方案 在链接生成动态库时,指定下面的链接选项: LDFLAG+=-read_only_relocs suppress https://blog.csdn.net/shengpeng3344/article/details/52998224 2. 这里有关于illegal text-relocation的说明 大致意思:当一个全局变量被编译到动态库中,而第三方asm代码需要引用该变量时,连接器会把相对地址付给相应引用...

When this option is on, the compiler places these tables in a read-only section (.rodata), allowing the linker to place this object code in a ROM image instead of RAM. When this option isoff, the compiler places these switch tables in an object code section that is readable and ...
