Recently the LE passive scanning and auto-connections feature was introduced. It uses the hci_connect_le() API which returns a hci_conn along with a reference count to that object. All previous users would tie this returned reference to some existing object, such as an L2CAP channel, and there'd be no leaked references this way. For auto-connections however the reference was returned but not stored anywhere, leaving established connections with one higher reference count than they should have. Instead of playing special tricks with hci_conn_hold/drop this patch associates the returned reference from hci_connect_le() with the object that in practice does own this reference, i.e. the hci_conn_params struct that caused us to initiate a connection in the first place. Once the connection is established or fails to establish this reference is removed appropriately. One extra thing needed is to call hci_pend_le_actions_clear() before calling hci_conn_hash_flush() so that the reference is cleared before the hci_conn objects are fully removed.

This patch drops the userspace accessable sysfs entry for the maximum datagram size of a 6LoWPAN fragment packet. A fragment should not have a datagram size value greater than 1280 byte. Instead of make this value configurable, we accept 1280 datagram size fragment packets only.

This patch changes the 1281 MTU to 1280. Others stack have only a 1280 byte array for uncompressed 6LoWPAN packets, this avoid that these stacks have an overflow.

The driver assumes that endpoint 4 is always an interrupt endpoint. Unfortunately the type differs between high-speed and full-speed configurations while in the former case it is indeed an interrupt endpoint this is not true for the latter case - here it is a bulk endpoint. When sending URBs with the wrong type the kernel will generate a warning message including backtrace. In this specific case there will be a huge amount of warnings which can bring the system to freeze. To fix this we are now sending URBs to endpoint 4 using the type found in the endpoint descriptor. A side note: The carl9170 firmware currently specifies endpoint 4 as interrupt endpoint even in the full-speed configuration but this has no relevance because before this firmware is loaded the endpoint type is as described above and after the firmware is running the stick is not reenumerated and so the old descriptor is used.

Pull ACPI and power management updates from Rafael Wysocki: "Again, ACPICA leads the pack (47 commits), followed by cpufreq (18 commits) and system suspend/hibernation (9 commits). From the new code perspective, the ACPICA update brings ACPI 5.1 to the table, including a new device configuration object called _DSD (Device Specific Data) that will hopefully help us to operate device properties like Device Trees do (at least to some extent) and changes related to supporting ACPI on ARM. Apart from that we have hibernation changes making it use radix trees to store memory bitmaps which should speed up some operations carried out by it quite significantly. We also have some power management changes related to suspend-to-idle (the "freeze" sleep state) support and more preliminary changes needed to support ACPI on ARM (outside of ACPICA). The rest is fixes and cleanups pretty much everywhere. Specifics: - ACPICA update to upstream version 20140724. That includes ACPI 5.1 material (support for the _CCA and _DSD predefined names, changes related to the DMAR and PCCT tables and ARM support among other things) and cleanups related to using ACPICA's header files. A major part of it is related to acpidump and the core code used by that utility.

Although RCU protection would be possible during diag dump, doing so allows for concurrent table mutations which can render the in-table offset between individual Netlink messages invalid and thus cause legitimate sockets to be skipped in the dump.

c90 section "6.7.2 Type Specifiers" says: "type specifiers may occur in any order" That means that: short int is the same as int short unsigned short int is the same as int unsigned short etc... checkpatch currently parses only a subset of these allowed types. For instance: "unsigned short" and "signed short" are found by checkpatch as a specific type, but none of the or "int short" or "int signed short" variants are found. Add another table for the "kernel style misordered" variants. Add this misordered table to the findable types. Warn when the misordered style is used. This improves the "Missing a blank line after declarations" test as it depends on the correct parsing of the $Declare variable which looks for "$Type $Ident;" (ie: declarations like "int foo;").

This can be valuable to insert or delete blank lines as well as fix misplaced brace or else uses. Store indexes of lines to be added/deleted and the new lines. When creating the --fix file, insert or delete the appropriate lines and update the patch range information.

Make the fix code a bit easier to read. This should also start to allow an easier mechanism to insert/delete lines eventually too.

Using break; after a goto or return is unnecessary so emit a warning when the break is at the same indent level. So this emits a warning on: switch (foo) { case 1: goto err; break; } but not on: switch (foo) { case 1: if (bar()) goto err; break; } Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Whenever files are added, moved, or deleted, the MAINTAINERS file patterns can be out of sync or outdated. To try to keep MAINTAINERS more up-to-date, add a one-time warning whenever a patch does any of those.

Commit logs have various forms of commit id references. Try to standardize on a 12 character long lower case commit id along with a description of parentheses and the quoted subject line. ie: commit 0123456789ab ("commit description") If git and a git tree exists, look up the commit id and emit the appropriate line as part of the message.

Avoid matching allocs that appear to be known small multiplications of a sizeof with a constant because gcc as of 4.8 cannot optimize the code in a calloc() exactly the same way as an alloc(). Look for numeric constants or what appear to be upper case only macro #defines.
