By changing the exit condition of this loop, we ensure that a minimum of one data block will always be returned.

803bf5e | Michael Neuling | 10 February 2010, 21:56:42 UTC | fs/exec.c: restrict initial stack space expansion to rlimit When reserving stack space for a new process, make sure we're not attempting to expand the stack by more than rlimit allows. This fixes a bug caused by b6a2fea39318e43fee84fa7b0b90d68bed92d2ba ("mm: variable length argument support") and unmasked by fc63cf237078c86214abcb2ee9926d8ad289da9b ("exec: setup_arg_pages() fails to return errors"). This bug means that when limiting the stack to less the 20*PAGE_SIZE (eg. 80K on 4K pages or 'ulimit -s 79') all processes will be killed before they start. This is particularly bad with 64K pages, where a ulimit below 1280K will kill every process. To test, do: 'ulimit -s 15; ls' before and after the patch is applied. Before it's applied, 'ls' should be killed. After the patch is applied, 'ls' should no longer be killed. A stack limit of 15KB since it's small enough to trigger 20*PAGE_SIZE. Also 15KB not a multiple of PAGE_SIZE, which is a trickier case to handle correctly with this code. 4K pages should be fine to test with.

77c1ff3 | Andy Getzendanner | 11 February 2010, 04:04:48 UTC | vgaarb: fix incorrect dereference of userspace pointer. This patch corrects a userspace pointer dereference in the VGA arbiter in 2.6.32.1. copy_from_user() is used at line 822 to copy the contents of buf into kbuf, but a call to strncmp() on line 964 uses buf rather than kbuf. This problem led to a GPF in strncmp() when X was started on my x86_32 systems. X triggered the behavior with a write of "target PCI:0000:01:00.0" to /dev/vga_arbiter. The patch has been tested against 2.6.32.1 and observed to correct the GPF observed when starting X or manually writing the string "target PCI:0000:01:00.0" to /dev/vga_arbiter.

Fix this issue by splitting the i915 suspend into a freeze part a suspend part, where the latter is not executed before creating a hibernation image, and the i915 resume into a "low-level" resume part and a thaw part, where the former is not executed after the image has been created.

99fcb76 | Daniel Vetter | 07 February 2010, 15:20:18 UTC | drm/i915: Update write_domains on active list after flush. Before changing the status of a buffer with a pending write we will await upon a new flush for that buffer. So we can take advantage of any flushes posted whilst the buffer is active and pending processing by the GPU, by clearing its write_domain and updating its last_rendering_seqno -- thus saving a potential flush in deep queues and improves flushing behaviour upon eviction for both GTT space and fences. In order to reduce the time spent searching the active list for matching write_domains, we move those to a separate list whose elements are the buffers belong to the active/flushing list with pending writes. Orignal patch by Chris Wilson <chris@chris-wilson.co.uk>, forward-ported by me. In addition to better performance, this also fixes a real bug. Before this changes, i915_gem_evict_everything didn't work as advertised. When the gpu was actually busy and processing request, the flush and subsequent wait would not move active and dirty buffers to the inactive list, but just to the flushing list. Which triggered the BUG_ON at the end of this function. With the more tight dirty buffer tracking, all currently busy and dirty buffers get moved to the inactive list by one i915_gem_flush operation. I've left the BUG_ON I've used to prove this in there.

(ie they weren't just trying to reserve a port) Currently, if the loopback address is passed to rdma_bind_addr, no device is associated with the rdma_cm_id. Fix this. It turns out that important apps such as Open MPI depend on rdma_bind_addr() NOT associating any RDMA device when binding to a loopback address. Open MPI is being updated to deal with this, but at least until a new Open MPI release is available, maintain the previous behavior: allow rdma_bind_addr() to succeed, but do not bind to a device.

In this case, we emulate 64k pages with multiple 4k hash PTEs, however in hpte_need_flush() we incorrectly only mask the hardware page size from the address, instead of the logical page size.

ef286f6 | NeilBrown | 09 February 2010, 05:34:14 UTC | md: fix some lockdep issues between md and sysfs. ====== This fix is related to http://bugzilla.kernel.org/show_bug.cgi?id=15142 but does not address that exact issue. ====== sysfs does like attributes being removed while they are being accessed (i.e. read or written) and waits for the access to complete. As accessing some md attributes takes the same lock that is held while removing those attributes a deadlock can occur. This patch addresses 3 issues in md that could lead to this deadlock. Two relate to calling flush_scheduled_work while the lock is held. This is probably a bad idea in general and as we use schedule_work to delete various sysfs objects it is particularly bad. In one case flush_scheduled_work is called from md_alloc (called by md_probe) called from do_md_run which holds the lock. This call is only present to ensure that ->gendisk is set. However we can be sure that gendisk is always set (though possibly we couldn't when that code was originally written. This is because do_md_run is called in three different contexts: 1/ from md_ioctl. This requires that md_open has succeeded, and it fails if ->gendisk is not set. 2/ from writing a sysfs attribute. This can only happen if the mddev has been registered in sysfs which happens in md_alloc after ->gendisk has been set. 3/ from autorun_array which is only called by autorun_devices, which checks for ->gendisk to be set before calling autorun_array. So the call to md_probe in do_md_run can be removed, and the check on ->gendisk can also go. In the other case flush_scheduled_work is being called in do_md_stop, purportedly to wait for all md_delayed_delete calls (which delete the component rdevs) to complete. However there really isn't any need to wait for them - they have already been disconnected in all important ways. The third issue is that raid5->stop() removes some attribute names while the lock is held. There is already some infrastructure in place to delay attribute removal until after the lock is released (using schedule_work). So extend that infrastructure to remove the raid5_attrs_group. This does not address all lockdep issues related to the sysfs "s_active" lock. The rest can be address by splitting that lockdep context between symlinks and non-symlinks which hopefully will happen.
