Mike Frysinger [Mon, 21 Feb 2011 22:19:35 +0000 (17:19 -0500)]
linuxthreads.old: fix nommu initial thread stack detection
Because the nommu address space is flat, and the application stack can
literally be located anywhere, we cannot rely on the assumptions that the
mmu port gets away with. Namely, that the first thread's stack lives at
the top of memory and nothing will be created above it.
Currently, the code rounds the current stack up a page and sets that as
the "top" of the stack, and then marks the "bottom" of the stack as "1".
Then as new threads are created, this assumption is further refined by
slowly backing off the "bottom" when a new stack is created within the
range of the initial stack.
Simple ascii example (tid0 is the initial thread):
1 thread:
[bos tid0 stack tos]
2 threads:
[ tid0 stack ]
[tid1 stack]
3 threads:
[ tid0 stack ]
[tid1 stack]
[tid2 stack]
As you can kind of see, this algorithm operates on one basic assumption:
the initial top of stack calculation is the absolute top of the stack.
While this assumption was fairly safe in the original nommu days of yore
where the only file format was FLAT (which defaults to a 4KiB stack --
exactly 1 page), and memory was fairly tight, we can see that this falls
apart pretty quickly as soon as the initial stack is larger than a page.
The issue that crops up now is simple to hit: start an application with
an 8KiB stack, execute some functions that put pressure on the stack so
that it exceeds 4KiB, then start up some threads. The initial tos will
be rounded up by a page, but this is actually the middle of the stack.
Now when the initial thread returns from its functions (thus unwinding
the stack) and tries to call something which calls back into libpthread,
the thread_self() func fails to detect itself as the initial thread as
the current stack is now above the tos. The __pthread_find_self() func
kicks in, walks all the thread arrays, fails to find a hit, and then
walks into uninitialized memory for the thread descriptor. Use of this
garbage memory has obvious results -- things fall down & go boom.
To address this, I extend the current algorithm to automatically scale
back both the bottom and the top stack limits of the initial thread.
We use the current stack pointer at "thread boot time" only as a single
known point. The initial thread stack bottom is set to the bottom of
memory and the initial thread stack top is set to the top of memory.
Then as we create new stack threads, we figure out whether the new stack
is above or below the single known good address, and then scale back
either the tos or the bos accordingly.

ldso: fix fdpic builds
Commit
33cb7f0b4 tried to add a small optimization for skipping unnecessary
.dynamic adjustments, but did so by referencing an opaque type. While this
works for non-fdpic targets (since the type can be cast to an integer), it
falls apart for fdpic targets where the type is actually a structure.
Since FDPIC can't support this optimization without walking a series of
linked structures, just skip it.

*printf: Violation of precision with null string
When a string format is processed and the argument is NULL, this yields
"(null)" regardless of precision. This does not make sense, precision
should not be exceeded. A simple test shows that glibc outputs nothing
if precision is smaller than six and the attached patch implements this
same behaviour.
Consider the not uncommon case of strings implemented like this:
struct string { int len; char *ptr; };
There is often no nultermination and they may be printed like this:
printf("%.*s", string.len, string.ptr);
If len is 0 then ptr may be anything, but NULL is a common value.
Obviously the empty string would be expected, not "(null)".
