2010-07-14xfrm: do not assume that template resolving always returns xfrmsTimo Teräs1-2/+13
xfrm_resolve_and_create_bundle() assumed that, if policies indicated presence of xfrms, bundle template resolution would always return some xfrms. This is not true for 'use' level policies which can result in no xfrm's being applied if there is no suitable xfrm states. This fixes a crash by this incorrect assumption.

2010-07-14hostap_pci: set dev->base_addr during probeJohn W. Linville1-0/+1
"hostap: Protect against initialization interrupt" (which reinstated "wireless: hostap, fix oops due to early probing interrupt") reintroduced Bug 16111. This is because hostap_pci wasn't setting dev->base_addr, which is now checked in prism2_interrupt. As a result, initialization was failing for PCI-based hostap devices. This corrects that oversight.

The commit 83ba9ea8a04b72dfee2515428c15e7414ba4fc61 ommitted the return line for the old synaptics model accidentally. This resulted in a wrong check, namely, the dimensions are checked for the old devices that don't support the query properly. This patch adds the return line back.

2010-07-12ocfs2: tighten up strlen() checkingDan Carpenter1-1/+1
This function is only called from one place and it's like this: dlm_register_domain(conn->cc_name, dlm_key, &fs_version); The "conn->cc_name" is 64 characters long. If strlen(conn->cc_name) were equal to O2NM_MAX_NAME_LEN (64) that would be a bug because strlen() doesn't count the NULL character. In fact, if you look how O2NM_MAX_NAME_LEN is used, it mostly describes 64 character buffers. The only exception is nd_name from struct o2nm_node. Anyway I looked into it and in this case the domain string comes from osb->uuid_str in ocfs2_setup_osb_uuid(). That's 32 characters and NULL which easily fits into O2NM_MAX_NAME_LEN. This patch doesn't change how the code works, but I think it makes the code a little cleaner. Signed-off-by: Dan Carpenter <[email protected]> Signed-off-by: Joel Becker <[email protected]>
2010-07-12ocfs2: Make xattr reflink work with new local alloc reservation.Tao Ma1-36/+90
The new reservation code in local alloc has add the limitation that the caller should handle the case that the local alloc doesn't give use enough contiguous clusters. It make the old xattr reflink code broken. So this patch udpate the xattr reflink code so that it can handle the case that local alloc give us one cluster at a time.

2010-07-12ocfs2: make xattr extension work with new local alloc reservation.Tao Ma1-29/+45
The old ocfs2_xattr_extent_allocation is too optimistic about the clusters we can get. So actually if the file system is too fragmented, ocfs2_add_clusters_in_btree will return us with EGAIN and we need to allocate clusters once again. So this patch change it to a while loop so that we can allocate clusters until we reach clusters_to_add.

2010-07-12ocfs2: No need to zero pages past i_size.Joel Becker1-4/+18
When ocfs2 fills a hole, it does so by allocating clusters. When a cluster is larger than the write, ocfs2 must zero the portions of the cluster outside of the write. If the clustersize is smaller than a pagecache page, this is handled by the normal pagecache mechanisms, but when the clustersize is larger than a page, ocfs2's write code will zero the pages adjacent to the write. This makes sure the entire cluster is zeroed correctly. Currently ocfs2 behaves exactly the same when writing past i_size. However, this means ocfs2 is writing zeroed pages for portions of a new cluster that are beyond i_size. The page writeback code isn't expecting this. It treats all pages past the one containing i_size as left behind due to a previous truncate operation. Thankfully, ocfs2 calculates the number of pages it will be working on up front. The rest of the write code merely honors the original calculation. We can simply trim the number of pages to only cover the actual file data.

2010-07-11powerpc/fsl-booke: Fix address issue when using relocatable kernelsMatthew McClintock1-3/+1
When booting a relocatable kernel it needs to jump to the correct start address, which for BookE parts is usually unchanged regardless of the physical memory offset. Recent changes cause problems with how we calculate the start address, it was always adding the RMO into the start address which is incorrect. This patch only adds in the RMO offset if we are in the kexec code path, as it needs the RMO to work correctly. Instead of adding the RMO offset in in the common code path, we can just set r6 to the RMO offset in the kexec code path instead of to zero, and finally perform the masking in the common code path Signed-off-by: Matthew McClintock <[email protected]> Signed-off-by: Kumar Gala <[email protected]>

We essentially treat userspace as an entirely separate environment which isn't relevant to lockdep (lockdep doesn't monitor userspace.) We don't tell lockdep that IRQs will be enabled in that environment. Instead, when creating kernel threads (which is a rare event compared to entering/leaving userspace) we have to update the lockdep state. Do this by starting threads with IRQs disabled, and in the kthread helper, tell lockdep that IRQs are enabled, and enable them. This provides lockdep with a consistent view of the current IRQ state in kernel space. This also revert portions of 0d928b0b616d1c5c5fe76019a87cba171ca91633 which didn't fix the problem.

2010-07-09tracing: Add alignment to syscall metadata declarationsSteven Rostedt1-2/+4
For some reason if we declare a static variable and then assign it later, and the assignment contains a __attribute__((__aligned__(#))), some versions of gcc will ignore it. This caused the syscall meta data to not be compact in its section and caused a kernel oops when the section was being read. The fix for these versions of gcc seems to be to add the aligned attribute to the declaration as well. This fixes the BZ regression: https://bugzilla.kernel.org/show_bug.cgi?id=16353 Reported-by: Zeev Tarantov <[email protected]> Tested-by: Zeev Tarantov <[email protected]> Acked-by: Frederic Weisbecker <[email protected]> LKML-Reference: <[email protected]> Signed-off-by: Steven Rostedt <[email protected]>
