So there is no free space that can be allocated now. find no space and don't try to alloc new chunk, and then return ENOSPC BUG_ON() in __finish_chunk_alloc() was triggered. Fix this bug by allocating a new system metadata chunk before relocating the old one if we find there is no free space which can be allocated after setting the old block group to be read-only.

2011-07-27Btrfs: tag pages for writeback in syncJosef Bacik
Everybody else does this, we need to do it too. If we're syncing, we need to tag the pages we're going to write for writeback so we don't end up writing the same stuff over and over again if somebody is constantly redirtying our file.

2011-07-27Btrfs: fix enospc problems with delallocJosef Bacik
So I had this brilliant idea to use atomic counters for outstanding and reserved extents, but this turned out to be a bad idea. Consider this where we have 1 outstanding extent and 1 reserved extent Reserver Releaser atomic_dec(outstanding) now 0 atomic_read(outstanding)+1 get 1 atomic_read(reserved) get 1 don't actually reserve anything because they are the same atomic_cmpxchg(reserved, 1, 0) atomic_inc(outstanding) atomic_add(0, reserved) free reserved space for 1 extent Then the reserver now has no actual space reserved for it, and when it goes to finish the ordered IO it won't have enough space to do it's allocation and you get those lovely warnings.

2011-07-27Btrfs: use a worker thread to do cachingJosef Bacik
A user reported a deadlock when copying a bunch of files. This is because they were low on memory and kthreadd got hung up trying to migrate pages for an allocation when starting the caching kthread. The page was locked by the person starting the caching kthread. To fix this we just need to use the async thread stuff so that the threads are already created and we don't have to worry about deadlocks.

2011-07-27[SCSI] ipr: reorder error handling code to include iounmapJulia Lawall
The out_msi_disable label should be before cleanup_nomem to additionally benefit from the call to iounmap. Subsequent gotos are adjusted to go to out_msi_disable instead of cleanup_nomem, which now follows it. This is safe because pci_disable_msi does nothing if pci_enable_msi was not called. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ expression e1,e2; statement S; @@ e1 = pci_ioremap_bar(...); ... when != e1 = e2 when != iounmap(e1) when any ( if (<+...e1...+>) S | if(...) { ... return 0; } | if (...) { ... when != iounmap(e1) when != if (...) { ... iounmap(e1) ... } * return ...; } else S ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Acked-by: Brian King <brking@linux.vnet.ibm.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
2011-07-27[SCSI] pmcraid: reject negative request sizeDan Rosenberg
There's a code path in pmcraid that can be reached via device ioctl that causes all sorts of ugliness, including heap corruption or triggering the OOM killer due to consecutive allocation of large numbers of pages. First, the user can call pmcraid_chr_ioctl(), with a type PMCRAID_PASSTHROUGH_IOCTL. This calls through to pmcraid_ioctl_passthrough(). Next, a pmcraid_passthrough_ioctl_buffer is copied in, and the request_size variable is set to buffer->ioarcb.data_transfer_length, which is an arbitrary 32-bit signed value provided by the user. If a negative value is provided here, bad things can happen. For example, pmcraid_build_passthrough_ioadls() is called with this request_size, which immediately calls pmcraid_alloc_sglist() with a negative size. The resulting math on allocating a scatter list can result in an overflow in the kzalloc() call (if num_elem is 0, the sglist will be smaller than expected), or if num_elem is unexpectedly large the subsequent loop will call alloc_pages() repeatedly, a high number of pages will be allocated and the OOM killer might be invoked. It looks like preventing this value from being negative in pmcraid_ioctl_passthrough() would be sufficient.

2011-07-27[SCSI] bnx2fc: Introduce interface structure for each vlan interfaceBhanu Prakash Gollapudi
Currently, bnx2fc has a hba structure that can work with only a single vlan interface. When there is a change in vlan id, it does not have the capability to switch to different vlan interface. To solve this problem, a new structure called 'interface' has been introduced, and each hba can now have multiple interfaces, one per vlan id. Most of the patch is a moving the interface specific fields from hba to the interface structure, and appropriately modifying the dereferences. A list of interfaces (if_list) is maintained along with adapter list. During a create call, the interface structure is allocated and added to if_list and deleted & freed on a destroy call. Link events are propagated to all interfaces belonging to the hba. Signed-off-by: Bhanu Prakash Gollapudi <bprakash@broadcom.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
