2011-03-08Btrfs: make sure not to return overlapping extents to fiemapChris Mason1-6/+27
The btrfs fiemap code was incorrectly returning duplicate or overlapping extents in some cases. cp was blindly trusting this result and we would end up with a destination file that was bigger than the original because some bytes were copied twice. The fix here adjusts our offsets to make sure we're always moving forward in the fiemap results. Signed-off-by: Chris Mason <[email protected]>
2011-03-08unfuck proc_sysctl ->d_compare()Al Viro4-13/+31
a) struct inode is not going to be freed under ->d_compare(); however, the thing PROC_I(inode)->sysctl points to just might. Fortunately, it's enough to make freeing that sucker delayed, provided that we don't step on its ->unregistering, clear the pointer to it in PROC_I(inode) before dropping the reference and check if it's NULL in ->d_compare(). b) I'm not sure that we *can* walk into NULL inode here (we recheck dentry->seq between verifying that it's still hashed / fetching dentry->d_inode and passing it to ->d_compare() and there's no negative hashed dentries in /proc/sys/*), but if we can walk into that, we really should not have ->d_compare() return 0 on it! Said that, I really suspect that this check can be simply killed. Nick? Signed-off-by: Al Viro <[email protected]>

2011-03-07bonding 802.3ad: Fix the state machine locking v2Nils Carlson1-5/+11
Changes since v1: * Clarify an unclear comment * Move a (possible) name change to a separate patch The ad_rx_machine, ad_periodic_machine and ad_port_selection_logic functions all inspect and alter common fields within the port structure. Previous to this patch, only the ad_rx_machines were mutexed, and the periodic and port_selection could run unmutexed against an ad_rx_machine trigged by an arriving LACPDU. This patch remedies the situation by protecting all the state machines from concurrency. This is accomplished by locking around all the state machines for a given port, which are executed at regular intervals; and the ad_rx_machine when handling an incoming LACPDU.

2011-03-07net: fix multithreaded signal handling in unix recv routinesRainer Weikusat1-4/+13
The unix_dgram_recvmsg and unix_stream_recvmsg routines in net/af_unix.c utilize mutex_lock(&u->readlock) calls in order to serialize read operations of multiple threads on a single socket. This implies that, if all n threads of a process block in an AF_UNIX recv call trying to read data from the same socket, one of these threads will be sleeping in state TASK_INTERRUPTIBLE and all others in state TASK_UNINTERRUPTIBLE. Provided that a particular signal is supposed to be handled by a signal handler defined by the process and that none of this threads is blocking the signal, the complete_signal routine in kernel/signal.c will select the 'first' such thread it happens to encounter when deciding which thread to notify that a signal is supposed to be handled and if this is one of the TASK_UNINTERRUPTIBLE threads, the signal won't be handled until the one thread not blocking on the u->readlock mutex is woken up because some data to process has arrived (if this ever happens). The included patch fixes this by changing mutex_lock to mutex_lock_interruptible and handling possible error returns in the same way interruptions are handled by the actual receive-code.

2011-03-07Btrfs: deal with short returns from copy_from_userChris Mason1-0/+13
When copy_from_user is only able to copy some of the bytes we requested, we may end up creating a partially up to date page. To avoid garbage in the page, we need to treat a partial copy as a zero length copy. This makes the rest of the file_write code drop the page and retry the whole copy instead of marking the partially up to date page as dirty.

2011-03-07Btrfs: fix regressions in copy_from_user handlingChris Mason1-42/+59
Commit 914ee295af418e936ec20a08c1663eaabe4cd07a fixed deadlocks in btrfs_file_write where we would catch page faults on pages we had locked. But, there were a few problems: 1) The x86-32 iov_iter_copy_from_user_atomic code always fails to copy data when the amount to copy is more than 4K and the offset to start copying from is not page aligned. The result was btrfs_file_write looping forever retrying the iov_iter_copy_from_user_atomic We deal with this by changing btrfs_file_write to drop down to single page copies when iov_iter_copy_from_user_atomic starts returning failure. 2) The btrfs_file_write code was leaking delalloc reservations when iov_iter_copy_from_user_atomic returned zero. The looping above would result in the entire filesystem running out of delalloc reservations and constantly trying to flush things to disk. 3) btrfs_file_write will lock down page cache pages, make sure any writeback is finished, do the copy_from_user and then release them. Before the loop runs we check the first and last pages in the write to see if they are only being partially modified. If the start or end of the write isn't aligned, we make sure the corresponding pages are up to date so that we don't introduce garbage into the file. With the copy_from_user changes, we're allowing the VM to reclaim the pages after a partial update from copy_from_user, but we're not making sure the page cache page is up to date when we loop around to resume the write. We deal with this by pushing the up to date checks down into the page prep code. This fits better with how the rest of file_write works.

Andi Kleen narrowed his GPU hangs on his Sugar Bay (SNB desktop) rev 09 down to the use of GPU semaphores, and we already know that they appear broken up to Huron River (mobile) rev 08. (I'm optimistic that disabling GPU semaphores is simply hiding another bug by the latency and side-effects of the additional device interaction it introduces...) However, use of semaphores is a massive performance improvement... Only as long as the system remains stable. Enable at your peril.

Whilst the GT is powered down (rc6), writes to MMADDR are placed in a FIFO by the System Agent. This is a limited resource, only 64 entries, of which 20 are reserved for Display and PCH writes, and so we must take care not to queue up too many writes. To avoid this, there is counter which we can poll to ensure there are sufficient free entries in the fifo.

2011-03-04mm: use correct numa policy node for transparent hugepagesAndi Kleen2-8/+19
Pass down the correct node for a transparent hugepage allocation. Most callers continue to use the current node, however the hugepaged daemon now uses the previous node of the first to be collapsed page instead. This ensures that khugepaged does not mess up local memory for an existing process which uses local policy. The choice of node is somewhat primitive currently: it just uses the node of the first page in the pmd range. An alternative would be to look at multiple pages and use the most popular node. I used the simplest variant for now which should work well enough for the case of all pages being on the same node.

2011-03-04mm: preserve original node for transparent huge page copiesAndi Kleen1-2/+2
This makes a difference for LOCAL policy, where the node cannot be determined from the policy itself, but has to be gotten from the original page.

2011-03-04mm: add alloc_page_vma_node()Andi Kleen1-0/+2
Add a alloc_page_vma_node that allows passing the "local" node in. Used in a followon patch.

2011-03-04mm: change alloc_pages_vma to pass down the policy node for local policyAndi Kleen3-11/+11
Currently alloc_pages_vma() always uses the local node as policy node for the LOCAL policy. Pass this node down as an argument instead. No behaviour change from this patch, but will be needed for followons.

2011-03-04pps: make pps_gen_parport depend on BROKENThomas Gleixner1-1/+1
This driver causes hard lockups, when the active clock soure is jiffies. The reason is that it loops with interrupts disabled waiting for a timestamp to be reached by polling getnstimeofday(). Though with a jiffies clocksource, when that code runs on the same CPU which is responsible for updating jiffies, then we loop in circles for ever simply because the timer interrupt cannot update jiffies. So both UP and SMP can be affected. There is no easy fix for that problem so make it depend on BROKEN for now.
