Thomas Gleixner [Thu, 11 Jun 2009 21:15:43 +0000 (23:15 +0200)]
futex: Fix the write access fault problem for real
commit
64d1304a64 (futex: setup writeable mapping for futex ops which
modify user space data) did address only half of the problem of write
access faults.
The patch was made on two wrong assumptions:
1) access_ok(VERIFY_WRITE,...) would actually check write access.
On x86 it does _NOT_. It's a pure address range check.
2) a RW mapped region can not go away under us.
That's wrong as well. Nobody can prevent another thread to call
mprotect(PROT_READ) on that region where the futex resides. If that
call hits between the get_user_pages_fast() verification and the
actual write access in the atomic region we are toast again.
The solution is to not rely on access_ok and get_user() for any write
access related fault on private and shared futexes. Instead we need to
fault it in with verification of write access.
There is no generic non destructive write mechanism which would fault
the user page in trough a #PF, but as we already know that we will
fault we can as well call get_user_pages() directly and avoid the #PF
overhead.
If get_user_pages() returns -EFAULT we know that we can not fix it
anymore and need to bail out to user space.
Remove a bunch of confusing comments on this issue as well.

The existing code had the following race:
Thread-1 Thread-2
inc/read in_use
inc/read in_use
inc tx_free_list[qos].len
inc tx_free_list[qos].len
The actual in_use value was incremented twice, but thread-1 is going
to free memory based on its stale value, and will free one too many
times. The result is that memory is freed back to the kernel while
its packet is still in the transmit buffer. If the memory is
overwritten before it is transmitted, the hardware will put a valid
checksum on it and send it out (just like it does with good packets).
If by chance the TCP flags are clobbered but not the addresses or
ports, the result can be a broken TCP stream.
The fix is to track the number of freed packets in a single location
(a Fetch-and-Add Unit register). That way it can never get out of sync
with itself.
We try to free up to MAX_SKB_TO_FREE (currently 10) buffers at a time.
If fewer are available we adjust the free count with the difference.
The action of claiming buffers to free is atomic so two threads cannot
claim the same buffers.

reiserfs: minimal fix for ACL caching
reiserfs uses NULL as "unknown" and ERR_PTR(-ENODATA) as "no ACL";
several codepaths store the former instead of the latter.
All those codepaths go through iset_acl() and all cases when it's
called with NULL acl are for the second variety, so the minimal
fix is to teach iset_acl() to deal with that.
Proper fix is to switch to more usual conventions and avoid back

Make allocation of anon devices cheaper
Standard trick - add a new variable (start) such that
for each n < start n is known to be busy. Allocation can
skip checking everything in [0..start) and if it returns
n, we can set start to n + 1. Freeing below start sets
start to what we'd just freed.
Of course, it still sucks if we do something like
free 0

drm/radeon: fix driver initialization order so radeon kms can be builtin
TTM need to be initialized before radeon if KMS is enabled otherwise
the kernel will crash hard.

drm: Fix shifts which were miscalculated when converting from bitfields.
Looks like I managed to mess up most shifts when converting from bitfields. :(
The patch below works on my Thinkpad T500 (as well as on my PowerBook,
where the previous change worked as well, maybe out of luck...). I'd
appreciate more testing and eyes looking over it though.

drm/radeon: Clear surface registers at initialization time.
Some PowerMac firmwares set up a tiling surface at the beginning of VRAM
which messes us up otherwise.

drm/radeon: Don't initialize acceleration related fields of struct fb_info.
Might lure userspace into trying silly things otherwise.

drm/radeon: fix radeon kms framebuffer device
smem.start is a physical address which kernel can remap to access
video memory of the fb buffer. We now pin the fb buffer into vram
by doing so we are loosing vram but fbdev need to be reworked to
allow change in framebuffer address.
