Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[IA64] Change SET_PERSONALITY to comply with comment in binfmt_elf.c. We have a customer application which trips a bug. The problem arises when a driver attempts to call do_munmap on an area which is mapped, but because current->thread.task_size has been set to 0xC0000000, the call to do_munmap fails thinking it is an unmap beyond the user's address space. The comment in fs/binfmt_elf.c in load_elf_library() before the call to SET_PERSONALITY() indicates that task_size must not be changed for the running application until flush_thread, but is for ia64 executing ia32 binaries. This patch moves the setting of task_size from SET_PERSONALITY() to flush_thread() as indicated. The customer application no longer is able to trip the bug.
