2007-10-22[NET]: Fix SKB_WITH_OVERHEAD calculationHerbert Xu
The calculation in SKB_WITH_OVERHEAD is incorrect in that it can cause an overflow across a page boundary which is what it's meant to prevent. In particular, the header length (X) should not be lumped together with skb_shared_info. The latter needs to be aligned properly while the header has no choice but to sit in front of wherever the payload is. Therefore the correct calculation is to take away the aligned size of skb_shared_info, and then subtract the header length. The resulting quantity L satisfies the following inequality: SKB_DATA_ALIGN(L + X) + sizeof(struct skb_shared_info) <= PAGE_SIZE This is the quantity used by alloc_skb to do the actual allocation.

2007-10-22[Bluetooth] Add support for handling simple eSCO linksMarcel Holtmann
With the Bluetooth 1.2 specification the Extended SCO feature for better audio connections was introduced. So far the Bluetooth core wasn't able to handle any eSCO connections correctly. This patch adds simple eSCO support while keeping backward compatibility with older devices. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2007-10-22[Bluetooth] Fall back to L2CAP in basic modeMarcel Holtmann

2007-10-22[Bluetooth] Retrieve L2CAP features mask on connection setupMarcel Holtmann
The Bluetooth 1.2 specification introduced a specific features mask value to interoperate with newer versions of the specification. So far this piece of information was never needed, but future extensions will rely on it. This patch adds a generic way to retrieve this information only once per connection setup. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2007-10-22[Bluetooth] Remove global conf_mtu variable from L2CAPMarcel Holtmann
After the change to the L2CAP configuration parameter handling the global conf_mtu variable is no longer needed and so remove it. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2007-10-22[Bluetooth] Switch from OGF+OCF to using only opcodesMarcel Holtmann
The Bluetooth HCI commands are divided into logical OGF groups for easier identification of their purposes. While this still makes sense for the written specification, its makes the code only more complex and harder to read. So instead of using separate OGF and OCF values to identify the commands, use a common 16-bit opcode that combines both values. As a side effect this also reduces the complexity of OGF and OCF calculations during command header parsing. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

2007-10-21[PATCH] audit: watching subtreesAl Viro
New kind of audit rule predicates: "object is visible in given subtree". The part that can be sanely implemented, that is. Limitations: * if you have hardlink from outside of tree, you'd better watch it too (or just watch the object itself, obviously) * if you mount something under a watched tree, tell audit that new chunk should be added to watched subtrees * if you umount something in a watched tree and it's still mounted elsewhere, you will get matches on events happening there. New command tells audit to recalculate the trees, trimming such sources of false positives. Note that it's _not_ about path - if something mounted in several places (multiple mount, bindings, different namespaces, etc.), the match does _not_ depend on which one we are using for access.

2007-10-20dm io:ctl use constant struct sizeMilan Broz
Make size of dm_ioctl struct always 312 bytes on all supported architectures. This change retains compatibility with already-compiled code because it uses an embedded offset to locate the payload that follows the structure. On 64-bit architectures there is no change at all; on 32-bit we are increasing the size of dm-ioctl from 308 to 312 bytes. Currently with 32-bit userspace / 64-bit kernel on x86_64 some ioctls (including rename, message) are incorrectly rejected by the comparison against 'param + 1'. This breaks userspace lvrename and multipath 'fail_if_no_path' changes, for example. (BTW Device-mapper uses its own versioning and ignores the ioctl size bits. Only the generic ioctl compat code on mixed arches checks them, and that will continue to accept both sizes for now, but we intend to list 308 as deprecated and eventually remove it.)
