dc8c814ca3 Squashed commit of the following:
Fixed coding standard error in several files.  Use of while( is incorrect; a space is required between while and (.  Also ran tools/nxstyle and fix thoses complaints as well in most files.

    Changes to comply with coding standard.  Mostly focused on files with missing space after keyword in if(, switch(, and for(.  Offending files also got changes to comply with tools nxstyle.  If there were logs of nxstyle complaints, the file also got a taste of tools/indent.sh.  Still need to fix occurrences of while( with missing space.  There are a lot of them.

* sixlowpan: Fixes logic surrounding the Universal/Local bit. This bit represents whether the IID is locally/globally administered. The U/L bit is bit 1 of the MSB of the EUI-64. It should only be inverted in cases where there is a full EUI-64. In cases where the IID is derived from say, a short address, this bit should be forced to 0, indicating that it is locally administered.

Xbee getset txpwr

* drivers/wireless/ieee802154/xbee: Minor improvements to debug facilities.

* drivers/wireless/ieee802154/xbee: Add support for setting/getting tx power.

    TODO: The input/output arguments from the MLME primitive are intended to be an int32_t dbm value. However this change simply reports the power level register of the XBee. Need to add look-up table to back calculate the dbm value.

a8b6be4aaf The existence of the network driver ioctl() method should depend on CONFIG_NETDEV_IOCTL rather than CONFIG_NETDEV_PHY_IOCTL. The former enables the method, the later enables a subset of possible driver IOCTLs. This change should be basically a no-operation. The affected ioctl methods only support those subset of driver IOCTLs selected by CONFIG_NETDEV_PHY_IOCTL and the network logic will tolerate a nul ioctl method. 2018-01-22 08:17:45 -06:00

ieee802154: Simplifies notify() and rxframe() calls to a single notify() call. dataind's and all other "notifs" are now "primitives" which aligns with standard terminology

* mac802154: Adds missing breaks from case statement

* sixlowpan: Fixes bad logic where ACK is not requested if address is not a broadcast

* ieee802154: Simplification of "notifs" and "datainds" to generic primitives passed via a single notify call to the layer above the MAC

* Directories.mk should reference CONFIG_WIRELESS instead of CONFIG_DRIVERS_WIRELESS

* xbee_netdev: Network must be locked when calling sixlowpan_input

* sixlowpan: Reassembly buffer can't be freed if provided by radio driver

* sixlowpan: Don't free IOB if there is an error processing it as the MAC will try to pass it along to another receiver

* ieee802154: Adds basic logging to ieee802154_primitive.c

* Minor fixes after rebase

* xbee: Adds AT query timeout to retry if XBee doesn't respond to request

* same70-xplained: Adds Xbee support. Makes mikroBus slot Kconfig 'choice'

* mac802154: Removes unused function declaration

* drivers/mrf24j40: Fixes compilation error using . operator rather than -> operator

* mac802154_device: Changes a few mac802154_primtive_free's to ieee802154_primitive_free() and changes notif to primitive in a couple places.

* mac802154: Adds promiscous mode logic to bypass parsing of incoming frames. MAC char device also checks for promiscous mode and passes whole frames including header and FCS to the application if promiscous mode is enabled.

* sixlowpan: Fixes logic to correctly check if packet is large enough to include header.  This would cause packets to be considered too small when they are sufficiently sized.

* sixlowpan: Fixes forwarding logic to use forwarding device rather than received device to look up destination link layer address

* net/ipforward: Fixes typo that caused build error when IP forwarding was enabled with CONFIG_NET_ICMPv6_NEIGHBOR enabled as well.

7cc63f90d9 sched/semaphore: sem_trywait() modifies the errno value and, hence, should not be used within the OS. Use nxsem_trywait() instead. 2017-10-05 07:59:06 -06:00

9568600ab1 Squashed commit of the following:
This commit backs out most of commit b4747286b1.  That change was added because sem_wait() would sometimes cause cancellation points inappropriated.  But with these recent changes, nxsem_wait() is used instead and it is not a cancellation point.

    In the OS, all calls to sem_wait() changed to nxsem_wait().  nxsem_wait() does not return errors via errno so each place where nxsem_wait() is now called must not examine the errno variable.

    In all OS functions (not libraries), change sem_wait() to nxsem_wait().  This will prevent the OS from creating bogus cancellation points and from modifying the per-task errno variable.

    sched/semaphore:  Add the function nxsem_wait().  This is a new internal OS interface.  It is functionally equivalent to sem_wait() except that (1) it is not a cancellation point, and (2) it does not set the per-thread errno value on return.

    We discovered a problem with the samv7 mcan driver which results, under some circumstances, in a very high CPU load.

    The problem occurs, and is easily reproducible, if the device is connected to a CAN network with a wrongly configured CAN speed (baud rate). In our tests we set the CAN speed of the device to 1000000 and the speed of the other CAN nodes to 500000. The device is restarted and sends a CANopen “bootup message” to the CAN network. This results in huge amount of errors messages on the CAN bus, probably because of the CAN feature for acknowledging error messages. The error messages can’t be read by the device because of the misconfigured CAN speed, instead the CAN chip reports lots of errors, which are reported to the application which uses the CAN driver (CONFIG_CAN_ERRORS is enabled).

    The CAN errors are reported from the CAN chip via interrupts and thus the interrupt load is very high in this scenario. To fix the problem the driver now disables each RX error interrupt after it is occurred. The RX error interrupts are turned back on if at least one CAN message is received successfully.
