20a86dfc1b binfmt/ and sched/group: Re-architect the way that loadable ELF or NXFLAT modules are unloaded. Memory resources must be recovered when the task loaded into memory exits. The originmal implementatino used the death-of-child SIGCHLD signal to perform the unload. There are several problems with this: It is overly complex, it requires that the parent task stay resident while the loaded task runs, and it has fatal logic flaws in the protected and kernel model builds because the user signal handler attempts to run in the kernel address space. This commit corrects with using a mindlessly simply BINFMT callback when the task exits. 2018-08-05 08:09:54 -06:00

056d704cf9 This commit brings in a fragmentary, experimental implementation of NETLINK sockets. There is not too much to that socket support on this initial commit, just the netlink socketer framework. However, I decided to bring it into master because there is a enough that I would not want to lose what is in place. And since it is dependent on CONFIG_EXPERIMENATL, its presence on master should be innocuous.
Squashed commit of the following:

    net/netlink:  Mark netlink support as EXPERIMENTAL.
    net/netlink/netlink_sockif.c:  Add netlink_getpeername to the socket interface.
    net:  Add getpeeername() support for netlink sockets.
    include/netpacket/netlink.h:  Add a few more definitions and structures used at the NetLink interface.  Still missing many.
    net/netlink:  Add basic framework for Netlink socket support.
    include/:  Add basic Netlink definitions.

09ccd43d61 arch/arm/include/armv7-m, arch/arm/include/armv7-m, arch/arm/include/stm32f7: Add a configuration to enable workaround for r0p1 Errata 837070: Increasing priority usingwrite to BASEPRI does not take effect immediately.
This update is required to be serialized to the instruction stream meaning that after this update completes, it takes effect immediately and no exceptions of lower priority than the new boosted priority can pre-empt execution.  Because of this erratum, the priority boosting does not take place immediately, allowing the instruction after the MSR to be interrupted by an exception of lower priority than the new boosted priority. This effect is only limited to the next instruction. Subsequent instructions are guaranteed to see the new boosted priority.

This was raised in Bitbucket issue 113 from Vadzim Dambrouski.

22cd0d47fa This commit attempts remove some long standard confusion in naming and some actual problems that result from the naming confusion. The basic problem is the standard MTU does not include the size of the Ethernet header. For clarity, I changed the naming of most things called MTU to PKTSIZE. For example, CONFIG_NET_ETH_MTU is now CONFIG_NET_ETH_PKTSIZE.
This makes the user interface a little hostile.  People thing of an MTU of 1500 bytes, but the corresponding packet is really 1514 bytes (including the 14 byte Ethernet header).  A more friendly solution would configure the MTU (as before), but then derive the packet buffer size by adding the MAC header length.  Instead, we define the packet buffer size then derive the MTU.

The MTU is not common currency in networking.  On the wire, the only real issue is the MSS which is derived from MTU by subtracting the IP header and TCP header sizes (for the case of TCP).  Now it is derived for the PKTSIZE by subtracting the IP header, the TCP header, and the MAC header sizes.  So we should be all good and without the recurring 14 byte error in MTU's and MSS's.

Squashed commit of the following:

    Trivial update to fix some spacing issues.
    net/: Rename several macros containing _MTU to _PKTSIZE.
    net/: Rename CONFIG_NET_SLIP_MTU to CONFIG_NET_SLIP_PKTSIZE and similarly for CONFIG_NET_TUN_MTU.  These are not the MTU which does not include the size of the link layer header.  These are the full size of the packet buffer memory (minus any GUARD bytes).
    net/: Rename CONFIG_NET_6LOWPAN_MTU to CONFIG_NET_6LOWPAN_PKTSIZE and similarly for CONFIG_NET_TUN_MTU.  These are not the MTU which does not include the size of the link layer header.  These are the full size of the packet buffer memory (minus any GUARD bytes).
    net/: Rename CONFIG_NET_ETH_MTU to CONFIG_NET_ETH_PKTSIZE.  This is not the MTU which does not include the size of the link layer header.  This is the full size of the packet buffer memory (minus any GUARD bytes).
    net/: Rename the file d_mtu in the network driver structure to d_pktsize.  That value saved there is not the MTU.  The packetsize is the memory large enough to hold the maximum packet PLUS the size of the link layer header.  The MTU does not include the link layer header.

317c7c2aff arch/arm/src/samv7: Add ability for CAN BUS_OFF autorecovery according ISO11898-1:2015. With this change we added an ioctl for triggering the autorecovery sequence for BUS_OFF to the CAN-driver and the SAMV7 low-level driver. According the datasheet: If the device goes Bus_Off, it will set MCAN_CCCR.INIT of its own accord, stopping all bus activities. Once MCAN_CCCR.INIT has been cleared by the processor (application), the device will then wait for 129 occurrences of Bus Idle (129 * 11 consecutive recessive bits) before resuming normal operation. At the end of the Bus_Off recovery sequence, the Error Management Counters will be reset. During the waiting time after the resetting of MCAN_CCCR.INIT, each time a sequence of 11 recessive bits has been monitored, a Bit0 Error code is written to MCAN_PSR.LEC, enabling the processor to readily check up whether the CAN bus is stuck at dominant or continuously disturbed and to monitor the Bus_Off recovery sequence. MCAN_ECR.REC is used to count these sequences. 2018-07-04 07:48:59 -06:00

Squashed commit of the following:

    arch/arm/src/stm32:  Add Kconfig options needed by the HCI UART.  Various fixes to finally get a clean error free compile with no unexpected warnings.
    arch/arm/src/stm32:  In HCI UART, use spin_lock_irqsave() instead of enter_critical_section() whenever possible.
    arch/arm/src/stm32:  In HCI UART, fix up naming of configurations so that they are unique.  Still needs Kconfig settings.  Modify logic so that there can be multiple HCI UARTs, some supporting DMA and some not.
    arch/arm/src/stm32:  Integrate watermarks and software Rx flow control into the HCI UART driver.
    arch/arm/src/stm32:  Eliminate some HCI UART UART configuration options.  Per the HCI UART spec, the link will b 8 data bits, no parity, 1 stop bit... Always.
    arch/arm/src/stm32:  Trivial cleanup
    arch/arm/src/stm32:  Fixes most initial compilation issues STM32 HCI UART driver.  Still need to set up USART configuration parmeters for HCI UART
    arch/arm/src/stm32:  Completes first cut at STM32 HCI UART driver.
    arch/arm/src/stm32:  Completes most of read logic for HCI UART.  Still needs to be able to block if no read data is available.  Still missing write and flush logic.
    drivers/wireless:    Remove txenable from HCI UART methods.  arch/arm/src/stm32:  Reorganize some structures in HCI UART.
    arch/arm/src/stm32:  Still messaging the HCI uart driver.
    arch/arm/src/stm32:  Some trivial renaming.
    arch/arm/src/stm32:  A little more HCI-UART logic.
    arch/arm/src/stm32:  Initial setup to support HCI-UART.  Little more than the serial driver with some name changes and a few things removed.

0c007be4bd This comment adds (1) basic support for AF_BLUETOOTH sockets. The logic compiles but is still incomplete. Support for Bluetooth is general is still dependent on CONFIG_EXPERMIMENTAL because it is not yet ready for used.
Squashed commit of the following:

    wireless/bluetooth:  Some small changes that gets to a clean compile by just eliminating some incorrect implementations (still with a lot of warnings.  The logic is still incomplete but now not so lethal.
    wireless/bluetooth:  Restructuring:  Connection interfaces should internal to wireless/bluetooth.  include/nuttx/wireless/bt_conn.h removed and merged with wireless/bluetooth/bt_conn.h.  Several fix to get closer to bt_netdev.c compiling.  Need to design some not interfaces and use some existing interfaces to send and receiv packets.
    wireless/bluetooth: Some organization with some network device compile errors fixed.  Still not even close to compiling.
    net/bluetooth:  Fix numerous compile issues; Still open design issues with regard to the interface with the Bluetooth stack.
    wireless/bluetooth:  Create bt_netdev.c with a crude copy of mac802154_netdev.c.  Does not not even compile yet.
    include/nuttx/net:  Add bluetooth.h.  Content is not yet correct.

accef0ca9e This commit brings in the Bluetooth stack from the Intel/Zephyr arduino101_firmware_source-v1.tar package.
NOTE: This selection is marked EXPERIMENTAL.  It is incomplete and, hence, untested.  It still lacks any low-level Bluetooth drivers and is missing the network interface driver.

Squashed commit of the following:

    wireless/bluetooth:  Fixe last of compile issues.  Now compiles without errors or warnings.
    wireless/blutooth:  Add macros BT_GETUINT16() and BT_PUTUINT16().  Fix more compile errors.  Only one file now generates compile errors.
    wireless/bluetooth:  Add macros BT_LE162HOST() and BT_HOST2LE16().
    wireless/bluetooth:  Add bt_queue.c; begin fixing comple errors.  Many more compile problems yet to resolve.
    Kconfig edited online with Bitbucket
    wireless/bluetooth:  Struggling to remove nano_fifo logic:  Replace buffer management with IOB allocate... this changes some logic and might have some side effects.  Use messages queues instead of nano-fifos to inter-task communications.  nano-fifos still used in 'frag' logic... whatever that is.
    wireless/bluetooth:  Fix numerous typos introduced by an ill conceived search-and-replace.
    wireless/bluetooth:  Add message queue support to manage interthread buffer transfers.
    wireless/bluetooth:  Replace fibers with kernel threads.
    wireless/bluetooth:  Fix a few initial compile errors.  Just the tip of the iceberg.
    wireless/bluetooth:  Complete leveage of the bluetooth stack including public header files.
    wireless/bluetooth:  Complete leverage of all Bluetooth source files.  Still missing header files that defines the driver interface.  Also missing the network driver implementation.

6a405ead67 This commit adds a barbones FTDI FT80x driver. It is untested (I don't even have hardware yet and, hence, it is marked as EXPERIMENTAL
Squashed commit of the following:

    drivers/lcd:  Finishes off basic FT80X.  Still missing some niceties.
    drivers/lcd: Rethink FT80X display list interface.
    drivers/lcd:  More FT800x display list logic.  Still not complete.
    drivers/lcd:  Add some basic FT80x initialization logic.
    drivers/lcd:  Add ft80x display list IOCTL framework.  Still missing low level display list operations.
    drivers/lcd:  FT80x driver cannot be a standard LCD driver but must, instead, be a custom character driver.
    drivers/lcd:  Add FT800 co-processor commands and display list helpers.
    drivers/lcd:  Add SPI interface and framework for the initialization and the basic LCD driver.
    drivers/lcd:  Add beginnings of some FT80x implementation.
    drivers/lcd:  Add definitions for the FTDI FT801 part
    include/nuttx/lcd/ft800.h:  Add initial FT800 interface definition.
    drivers/lcd:  Add ft800 header file.

37c9b3d54a sched/sched: Implements a global scheduler lock capability as part of SMP support. This allows the scheduler to be locked with no knowledge or access to the TCB of the currently running task. This is necessary because accessing the TCB of the currenlty running task is, itself, a non-atomic operation. This global scheduler lock cpability was add just to support that atomic access to the TCB. 2018-02-05 13:12:36 -06:00
