Ian Wienand e384f41409 [IA64] set_thread_area fails in IA32 chroot ... I tried to upgrade an IA32 chroot on my IA64 to a new glibc with TLS. It kept dying because set_thread_area was returning -ESRCH (bugs.debian.org/451939). I instrumented arch/ia64/ia32/sys_ia32.c:get_free_idx() and ended up seeing output like [pid] idx desc->a desc->b ----------------------------- [2710] 0 -> c6b0ffff 40dff31b [2710] 1 -> 0 0 [2710] 2 -> 0 0 [2710] 0 -> c6b0ffff 40dff31b [2710] 1 -> c6b0ffff 40dff31b [2710] 2 -> 0 0 [2711] 0 -> c6b0ffff 40dff31b [2711] 1 -> c6b0ffff 40dff31b [2711] 2 -> 48c0ffff 40dff317 which suggested to me that TLS pointers were surviving exec() calls, leading to GDT pointers filling up and the eventual failure of get_free_idx(). I think the solution is flushing the tls array on exec. Signed-Off-By: Ian Wienand <ianw@gelato.unsw.edu.au> Signed-off-by: Tony Luck <tony.luck@intel.com>		2007-12-19 11:06:40 -08:00
