* netlink: make nlmsg_end() and genlmsg_end() voidJohannes Berg2015-01-184-14/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Contrary to common expectations for an "int" return, these functions return only a positive value -- if used correctly they cannot even return 0 because the message header will necessarily be in the skb. This makes the very common pattern of if (genlmsg_end(...) < 0) { ... } be a whole bunch of dead code. Many places also simply do return nlmsg_end(...); and the caller is expected to deal with it. This also commonly (at least for me) causes errors, because it is very common to write if (my_function(...)) /* error condition */ and if my_function() does "return nlmsg_end()" this is of course wrong. Additionally, there's not a single place in the kernel that actually needs the message length returned, and if anyone needs it later then it'll be very easy to just use skb->len there. Remove this, and make the functions void. This removes a bunch of dead code as described above. The patch adds lines because I did - return nlmsg_end(...); + nlmsg_end(...); + return 0; I could have preserved all the function's return values by returning skb->len, but instead I've audited all the places calling the affected functions and found that none cared. A few places actually compared the return value with <= 0 in dump functionality, but that could just be changed to < 0 with no change in behaviour, so I opted for the more efficient version. One instance of the error I've made numerous times now is also present in net/phonet/pn_netlink.c in the route_dumpit() function - it didn't check for <0 or <=0 and thus broke out of the loop every single time. I've preserved this since it will (I think) have caused the messages to userspace to be formatted differently with just a single message for every SKB returned to userspace. It's possible that this isn't needed for the tools that actually use this, but I don't even know what they are so couldn't test that changing this behaviour would be acceptable.

* ieee802154: 6lowpan: fix Makefile entryAlexander Aring2015-01-082-2/+2
| | | | | | | | | | | | | Since commit ea81ac2e7050798109356150ea16e71622a5c329 ("ieee802154: create 6lowpan sub-directory") we have a subdirectory for the ieee802154 6lowpan implementation. This commit also moves the Kconfig entry inside of net/ieee802154/6lowpan/ and forgot to rename the Makefile entry from obj-$(CONFIG_IEEE802154_6LOWPAN) to obj-y and handle the obj-$(CONFIG_IEEE802154_6LOWPAN) inside the created 6lowpan directory. This will occur that the ieee802154_6lowpan can't be build. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

Linville says: ==================== pull request: wireless-next 2014-12-08 Please pull this last batch of pending wireless updates for the 3.19 tree... For the wireless bits, Johannes says: "This time I have Felix's no-status rate control work, which will allow drivers to work better with rate control even if they don't have perfect status reporting. In addition to this, a small hwsim fix from Patrik, one of the regulatory patches from Arik, and a number of cleanups and fixes I did myself. Of note is a patch where I disable CFG80211_WEXT so that compatibility is no longer selectable - this is intended as a wake-up call for anyone who's still using it, and is still easily worked around (it's a one-line patch) before we fully remove the code as well in the future." For the Bluetooth bits, Johan says: "Here's one more bluetooth-next pull request for 3.19: - Minor cleanups for ieee802154 & mac802154 - Fix for the kernel warning with !TASK_RUNNING reported by Kirill A. Shutemov - Support for another ath3k device - Fix for tracking link key based security level - Device tree bindings for btmrvl + a state update fix - Fix for wrong ACL flags on LE links" And... "In addition to the previous one this contains two more cleanups to mac802154 as well as support for some new HCI features from the Bluetooth 4.2 specification. From the original request: 'Here's what should be the last bluetooth-next pull request for 3.19. It's rather large but the majority of it is the Low Energy Secure Connections feature that's part of the Bluetooth 4.2 specification. The specification went public only this week so we couldn't publish the corresponding code before that. The code itself can nevertheless be considered fairly mature as it's been in development for over 6 months and gone through several interoperability test events. Besides LE SC the pull request contains an important fix for command complete events for mgmt sockets which also fixes some leaks of hci_conn objects when powering off or unplugging Bluetooth adapters. A smaller feature that's part of the pull request is service discovery support. This is like normal device discovery except that devices not matching specific UUIDs or strong enough RSSI are filtered out. Other changes that the pull request contains are firmware dump support to the btmrvl driver, firmware download support for Broadcom BCM20702A0 variants, as well as some coding style cleanups in 6lowpan & ieee802154/mac802154 code.'" For the NFC bits, Samuel says: "With this one we get: - NFC digital improvements for DEP support: Chaining, NACK and ATN support added. - NCI improvements: Support for p2p target, SE IO operand addition, SE operands extensions to support proprietary implementations, and a few fixes. - NFC HCI improvements: OPEN_PIPE and NOTIFY_ALL_CLEARED support, and SE IO operand addition. - A bunch of minor improvements and fixes for STMicro st21nfcb and st21nfca" For the iwlwifi bits, Emmanuel says: "Major works are CSA and TDLS. On top of that I have a new firmware API for scan and a few rate control improvements. Johannes find a few tricks to improve our CPU utilization and adds support for a new spin of 7265 called 7265D. Along with this a few random things that don't stand out." And... "I deprecate here -8.ucode since -9 has been published long ago. Along with that I have a new activity, we have now better a infrastructure for firmware debugging. This will allow to have configurable probes insides the firmware. Luca continues his work on NetDetect, this feature is now complete. All the rest is minor fixes here and there." For the Atheros bits, Kalle says: "Only ath10k changes this time and no major changes. Most visible are: o new debugfs interface for runtime firmware debugging (Yanbo) o fix shared WEP (Sujith) o don't rebuild whenever kernel version changes (Johannes) o lots of refactoring to make it easier to add new hw support (Michal) There's also smaller fixes and improvements with no point of listing here." In addition, there are a few last minute updates to ath5k, ath9k, brcmfmac, brcmsmac, mwifiex, rt2x00, rtlwifi, and wil6210. Also included is a pull of the wireless tree to pick-up the fixes originally included in "pull request: wireless 2014-12-03"...

Most of it is again fixes and cleanups to ieee802154 related code from Alexander Aring. We've also got better handling of hardware error events along with a proper API for HCI drivers to notify the HCI core of such situations. There's also a minor fix for mgmt events as well as a sparse warning fix. The code for sending HCI commands synchronously also gets a fix where we might loose the completion event in the case of very fast HW (particularly easily reproducible with an emulated HCI device)." And... "Here's another bluetooth-next pull request for 3.19. We've got: - Various fixes, cleanups and improvements to ieee802154/mac802154 - Support for a Broadcom BCM20702A1 variant - Lots of lockdep fixes - Fixed handling of LE CoC errors that should trigger SMP" For the Atheros bits, Kalle says: "One ath6kl patch and rest for ath10k, but nothing really major which stands out. Most notable: o fix resume (Bartosz) o firmware restart is now faster and more reliable (Michal) o it's now possible to test hardware restart functionality without crashing the firmware using hw-restart parameter with simulate_fw_crash debugfs file (Michal)" On top of that...both ath9k and mwifiex get their usual level of updates.

| | | | | | | | | | | | | | | | | | This patch adds a new cfg802154_rdev_list to remember all registered cfg802154_registered_device structs. This is needed to prepare the upcomming nl802154 framework. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
| * ieee802154: rename wpan_phy_allocAlexander Aring2014-11-091-2/+2
| | | | | | | | | | | | | | | | This patch renames the wpan_phy_alloc function to wpan_phy_new. This naming convention is like wireless and "wiphy_new" function. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
| * 6lowpan: move skb_free from error paths in decompressionMartin Townsend2014-11-061-10/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently we ensure that the skb is freed on every error path in IPHC decompression which makes it easy to introduce skb leaks. By centralising the skb_free into the receive function it makes future decompression routines easier to maintain. It does come at the expense of ensuring that the skb passed into the decompression routine must not be copied.

| * ieee802154: remove mlme get_phy callbackAlexander Aring2014-11-053-11/+6
| | | | | | | | | | | | | | | | | | | | This patch removes the get_phy callback from mlme ops structure. Instead we doing a dereference via ieee802154_ptr dev pointer. For backwards compatibility we need to run get_device after dereference wpan_phy via ieee802154_ptr.

| * mac802154: move dev_hold out of ieee802154_if_addAlexander Aring2014-11-051-0/+1
| | | | | | | | | | | | | | | | | | This patch moves the dev_hold call inside of nl-phy ieee802154_add_iface function. The ieee802154_add_iface is the only one function which use the ieee802154_if_add function and contains the corresponding dev_put call.

| * ieee802154: remove nl802154 unused functionsAlexander Aring2014-11-051-181/+6
| | | | | | | | | | | | | | | | | | | | The include/net/nl802154.h file contains a lot of prototypes which are not used inside of ieee802154 subsystem. This patch removes this file and make the only one used prototype "ieee802154_nl_start_confirm" as static declaration in ieee802154/nl-mac.c Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
| * ieee802154: rework wpan_phy index assignmentAlexander Aring2014-11-052-19/+14
| | | | | | | | | | | | | | | | | | | | This patch reworks the wpan_phy index incrementation. It's now similar like wireless wiphy index incrementation. We move the wpan_phy index attribute inside of cfg802154_registered_device and use atomic operations instead locking mechanism via wpan_phy_mutex.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Running make C=2 occurs in warnings: symbol 'wpan_phy_class' was not declared. Should it be static? symbol 'wpan_phy_sysfs_init' was not declared. Should it be static? symbol 'wpan_phy_sysfs_exit' wasnot declared. Should it be static? This patch adds a missing include "sysfs.h" to solve these warnings.

| * ieee802154: 6lowpan: remove set of mac addressAlexander Aring2014-11-021-14/+0
| | | | | | | | | | | | | | | | | | | | Currently the ieee802154 6lowpan interface operates on wpan interfaces only. Setting the wpan mac address over 6lowpan interface is complex and maybe we can't never do this. This patch removes the set of mac address handling in ieee802154 6lowpan interface for now.
