* net/, include/, various files: Rename CONFIG_NET_RECEIVE_WINDOW to
CONFIG_NET_ETH_TCP_RECVWNDO and CONFIG_NET_SLIP_TCP_RECVWNDO. Add
data structures and logic to handler different TCP receive windows
when both Ethernet and SLIP are enabled (2014-11-16).
* configs/sama5d4-ek/bridge: Add a simple test for the dual EMACs on
the SAMA5D4 (2014-11-17).
* arch/arm/src/sama5/sam_emacb.c: Fix several typos that will prevent
EMAC1 from initializing properly (2014-11-17).
* include/nuttx/net/ip.h and tcp.h, net/icmp/icmp_send.c and
igmp/igmp_send.c: Move IP header flags from tcp.h to ip.h and rename
IP_FLAGS vs TCPFLAGS. The problem fixed here is that there IP flags
were not available when TCP was disabled. The IP flags are used in
ICMP and IGMP (2014-11-17).
* sched/clock/clock_abstime2ticks.c: Calling mq_timedreceived() with
immediate timeout was getting stuck and not timing out. Immediate
timeout is achieved by setting absolute timeout value to past time,
for example abstime={ .tv_sec=0, .tv_nsec=0 }. However absolute
time was converted to relative time using unsigned integer arithmetic
and resulted large ticks count by clock_abstime2ticks, instead of
expected negative ticks value. Change corrects clock_abstime2ticks()
to return negative ticks, if absolute time is in the past. From
Jussi Kivilinna (2014-11-19).
* fs/vfs/fs_poll.c: poll() was not waking up from signals (for example
mq_notify() events). From Jussi Kivilinna (2014-11-19).
* arch/arm/src/stm32/stm32_otghs.c, Make.defs,
configs/stm32f429i-disco/src/stm32_usb.c and Makefile: STM32 F4 OTGHS
device controller driver from Brennan Ashton (2014-11-20).
* configs/sama5d3-xplained/bridge: Add a simple test for the the EMAC
and GMAC on the SAMA5D3 working together (2014-11-20).
* libnx/nxtk/nxtk_drawframe.c: Remove warnings when CONFIG_NXTK_BORDERWIDTH
is set to zero. From Pierre-Noel Bouteville (2014-11-20).
* fs/vfs/fs_poll.c: Add proper handling for sem_timedwait errnos.
From Jussi Kivilinna (2014-11-21).
* net/udp/udp_conn.c and udp.h: Extensions to UDP "connection" structure
for the case of multiple networks. In this case, assigned port numbers
only have to be unique with respect to the IP address. So, for
example, you could have multiple port 80's, one on each network
(2014-11-21).
* net/tcp/tcp_conn.c and tcp.h: Make tcp_listener static scope; it is
not used outside of tcp_conn.c (2014-11-22).
* net/udp/tcp_conn.c and tcp.h: Extensions to TCP connection structure
for the case of multiple networks. See the description of the similar
change for UDP above (2014-11-22).
* net/route/net_router.c: Refuse to perform routing table lookups for
the Broadcast IP address. From Brennan Ashton.
* net/netdev/netdev_findbyaddr.c and netdev: Add logic to netdev_findbyaddr()
to return the correct network device for the case where a broadcast
address is used. This change caused trivial ripples through other
files because additional parameters are required for netdev_findbyaddr()
when CONFIG_NET_MULTINIC. Those other file include net/netdev/netdev_rxnotify.c,
netdev_txnotify.c which, in turn, for changes to arp/arp_send.c,
icmp/icmp_ping.c, socket/net_sendfile.c, recvfrom.c, sendto.c,
tcp/tcp_send_buffered.c, and tcp_send_unbuffered.c (2014-11-23).
* arch/arm/src/kl/chip/kl_i2c.h: I2C header file for the Freescale KL
* include/nuttx/fs/fs.h: Fix typo in conditional compilation. From
7.7 2015-xx-xx Gregory Nutt <gnutt@nuttx.org>
* nuttx/drivers/eeprom and include/nuttx/eeprom/: Add support for generic
EEPROM access via a character driver. Add also the EEPROM driver itself.
From Sébastien Lorquet (2014-11-26).
* libnx/nxfonts/nxfonts_pixel-lcd-machine.h and nxfonts_pixel-unicode.h,
include/nuttx/nx/nxfonts.h, graphpics/Kconfig, and build-related files
in libnx/nxfonts: Two new fonts from Pierre-noel Bouteville (2014-11-26).
* configs/lpc4357-evb, arch/arm/src/pc43xx/chip/, configs/Kconfig, and
and other related files: A port of NuttX to the LPC4357-EVB from
Toby Duckworth. This port is a leverage of the LPC3330-Xplorer port
and still have a some misinformation from that port that needs to be
updated for the LPC4357-EVB (2014-11-26).
* arch/arm/include/stm32/chip.h, src/stm32/Kconfig, chip.h, and
chip/stm32f102_pinmap.h: Enable support for the STM32 F102. From
https://github.com/PX4/NuttX/pull/28.diff (2014-11-27).
* drivers/loop.c: Loop device should return -EINTR is interrupt by a
signal (2014-11-27).
* drivers/input/djoystick.c and include/nuttx/input/djoystick.h. Also
drivers/input/Kconfig and Make.defs, and include/nuttx/fs/ioctl.h: Add
an interface definition and upper half driver for a discrete joystick
device (2014-11-27).
* arch/arm/src/efm32/Kconfig and efm32_serial.c: Add support for serial
termios TCGET and TCSET. For the moment, only set/get speed is
implemented. From Pierre-noel Bouteville (2014-11-27).

* drivers/wireless/ and include/nuttx/wireless/cc3000.h: A set of 11
patches correcting issues with the CC3000 networking. All from Jussi
Kivilinna (2014-11-28). Among these:
03/11: CC3000 driver was getting stuck at recv() when remote host
closed connection and application tried to read data from remotely
shutdown socket. This patch adds proper handling for remotely closed
socket event.
07/11: Socket state initialization was done in 'register', while it
should be initialized in 'open' and deinitialized in 'close'. Old
way caused problems when device is closed, power-cycled and then
reopened as old socket state was left enabled.
08/11: Select thread was getting stuck after 'close, power-cycle,
reopen', since selectsem was not properly setup and cleaned up.
09/11: 'maxFD' was not properly reset in select worker and not checked
for before calling cc3000_select().
10/11: After wlan_stop()/cc3000_close(), irqsem was left with count
'-1'. Therefore on next wlan_start()/cc3000_open(), initial value
for irqsem was wrong. Additional repeated wlan_start()/wlan_stop()
decreased irqsem value further. Obviously this causes driver not to
function correctly and freeze. Patch moves initialization and
destruction of waitsem, irqsem and readysem to
cc3000_open/cc3000_close.
* include/cxx/cctype: Undefine macros defined ctype.h so that builtin
C++ implementations will be used intead. From Lorenz Meier
(2014-11-28).
* configs/stm3210e-eval/src/stm32_djoystick.c: Add a discrete Joystick
supportfor the STM3210E-EVAL (2014-11-28).
* drivers/input/djoystick.c include/nuttx/input/djoystick.h: Add a new
ioctl to get the supported joystick discrete signals (2014-11-28).
* drivers/input/ajoystick.c and include/nuttx/input/ajoystick.h. Also
drivers/input/Kconfig and Make.defs, and include/nuttx/fs/ioctl.h: Add
an interface definition and upper half driver for an analog joystick
device. Initial check-in is only a little more of a clone of the
discrete joystick driver and is as-of-yet untested (2014-11-27).
* libc/Kconfig, misc/Make.defs, misc/lib_ioctl.c, fs/vfs/fs_ioctl.c,
include/nuttx/fs/fs.h, include/sys/ioctl.h, syscall.h, and several
files in syscall/: Add support for a variadic ioctl() function. The
ioctl() interface is a non-standard, Unix interface. NuttX has always
used the older, three-parameter version. Most contemporary systems
now, however, use a variadic form of the ioctl() function. Added an
option to insert a shim layer to adapt the three-parameter ioctl() to
use the variadic interface form. Internally, the ioctl handling is
the same three-parameter logic. The only real complexity to the shim
is in how the system calls must be handled (2014-11-29).
* arch/arm/src/stm32/stm32_i2c.c: Port Tridge's I2C noise resilience
logic from the PX4 repository (2014-11-29).
* arch/arm/src/stm32/chip/stm32l15xxx_pinmap.h: Fix a typo in the
MCO pin definition. From Jussi Kivilinna (2014-12-02).
* arch/arm/src/stm32/stm32_rcc.h: Add missing MCO configuration for
the STM32L1xxx. From Jussi Kivilinna (2014-12-02).
* configs/sama5d3-xplained/src/sam_ajoystick.c: Add analog Joystick
shield support for the SAMA5D3 Xplained board (2014-12-3).
* configs/ucleo-f4x1re/src/sam_ajoystick.c and sam_adc.c: Add
analog Joystick shield support for the Nucleo F4x1RE boards. There
are still some ADC issues to be worke through as of the initial
commit (2014-12-3).
* /drivers/eeprom/spi_xx25xx.c and /include/nuttx/eeprom/spi_xx25xx.h:
Add support for ST Micro EEPROM device geometries. From Sebastien
Lorquet (2014-12-5).
* sched/mqueue: msg type should be char * not void * in mq_send,
mq_timedsend, mq_receive, and mq_timedreceive. Noted by Pierre-Noel
Bouteville (2014-12-05).
* fs/mqueue/mq_open.c and sched/mqueue/mq_msgqalloc.c: In message queue
creation return ENOSPC error if size exceeds the configured size of
pre-allocated messages; Use ENOSPC vs ENOMEM per OpenGroup.org. From
Pierre-Noel Bouteville (2014-12-6).
* Add sys/custom_file.h. Used when CUSTOM_FILE_IO is define and avoids
re-definition errors about the FILE define. From Thomas Gruber via
the PX4 repository (2014-12-06).
* tools/bfd-converter.c and mkdeps.c: Eliminate a warnging about
redefined strtok_r on some platforms (2014-12-8).
* arch/sim/Kconfig: Allow building the simulated framebuffer driver
even if NX is not enabled (12014-12-8).
* configs/sim/traveler and README.txt: Add a configuration build and test
the Traveler firt person game using the simualtor (2014-12-8).
* arch/arm/src/stm32/chip/stm32f20xxx_pinmap.h and stm32f40xxx_pinmap.h:
Set the GPIO_SPEED_50MHz on all F2 and F4 SPI pin configurations.
This is based on an F411 SPI1 errata but the fixed is generalized to
all SPI and all F2 and F4 (let me know if this introduces any other
issues). Discovered and fixed by Sebastien Lorquet after much
consternation (2014-12-8).
* libc/stdio/lib_avsprintf.c: avsprintf(): Fix a bug in usage of
va_list on x86. On x86, va_list is a pointer to a single copy on the
stack. avsprintf() calls lib_vsprintf() twice and so traverses the
va_list twice using va_start. va_start modifies that single copy on
he stack so that the second call to lib_vsprintf() fails. This appears
to be an issue with x86 only so far (2014-12-8).
* stdint.h: Don't use hex values to specify minimum values of fixed
width, signed values. Hex values are inherently unsigned and not
usable for this purpose in all contexts (2014-12-8).
* arch/arm/src/tiva/tiva_i2c.c, tiva_i2c.h, Kconfig, and Make.defs: Add
build framework and skeleton files for Tiva I2C driver. Initial
commit is just the STM32 I2C driver with name changes and STM32-
specific logic removed (2014-12-9).
* fs/procfs/fs_procfs.c: Add procfs write support. From Ken Petit
(2014-12-9).
* include/crc8.h, libc/misc/lib_crc8.c, and Make.defs: Add CRC8 support.
From Ken Pettit (2014-12-9).
* drivers/mtd/smart.c, Kconfig, fs/smartfs/smartfs_smart.c,
smartfs_procfs.c, smartfs_utils.c, smartfs.h, Kconfig,
include/nuttx/fs/ioctl.h, smart.h, and mtd/smart.h: Implements wear-
leveling in the SmartFS. From Ken Pettit (2014-12-9).
* arch/arm/src/tiva/tiva_i2c.c: Drive is code complete but still
untested (2014-12-10).
* configs/tm4c123g-launchpad/src/tm4c_at24.c, tm4c_bringup.c, and other
files: Add initialization logic for an external AT24 EEPROM. This
is intended only to suppport testing of the Tiva I2C driver
(2014-12-10).
* libnx/Makefile, libnx/nxfonts/nxfonts_x11-misc-fixed-*.h, Make.defs,
Makefile.sources, nxfonts_bitmaps.c, graphics/Kconfig, and
include/nuttx/nx/nxfonts.h: Lots of fonts that derive from
X11-misc-fixed-* fonts. Converted for use by NuttX by Pierre-Noel
Bouteville (2014-12-10).
* nuttx/drivers/mtd/m25px.c; M25P serial flash driver: Add subsector
size of the M24P16 part. From Lazlo (2014-12-10).
* libc/string/lib_strncpy.c: Commit d0c76ccacf0dc8988f9617ad82bf4349f456bb08
will trash a lot of memory if n == 0. From Yasuhiro Osaki (2014-12-11).
* arch/arm/src/stm32/stm32_otghsdev.c. Fix for OTGHS device driver
working in FS mode. From Ken Pettit (2014-12-12).
* libc/stdio/lib_sscanf.c: Accept %X as well as %x as a format
specifier. From Sébastien Lorquet (2014-12-12).
* libc/stdio/lib_sscanf.c: Also accept %F as well as %f (2014-12-12).
* arch/arm/src/stm32/stm32_otghsdev.c: For STM32 OTG HS DEV (in FS
mode): Disable ULPI clock enable in RCC AHB1 Register. If Both ULPI
and the FS clock enable bits are set in FS mode, then the ARM never
awakens from WFI due to a chip issue. This is only an issue if you
are using the internal PHY. From Ken Pettit (2014-12-13).
* drivers/serial/serial.c: In case a thread is doing a blocking
operation (e.g. read()) on a serial device, while it is being
terminated by pthread_cancel(), then uart_close() gets called, but
the semaphore (dev->recv.sem in the above example) is still blocked.
This means that once the serial device is opened next time, data will
arrive on the serial port (and driver interrupts handled as normal),
but the received characters never arrive in the reader thread.
Th problem was fixed by re-initializing the semaphores on the last
uart_close() on the device. From Harald Welte (2014-12-13).
* sched/semaphore/sem_recover.c, Make.defs, seamphore.c,
sched/wdog/wd_recover.c, Make.defs, wdog.h, sched/task/task_recover.c:
Add logic to clean up after task_delete() or pthread_cancel() if the
task happens to be waiting on a semaphore when it is cancelled
(2014-12-13).
* arch/arm/src/kl/kl_gpioirq.c, Kconfig, Make.defs, and kl_irq.c: Add
GPIO interrupt capability for the KL architecture. The patch is
almost the same as kinetis_pinirq.c, just minor modifications and
rename kl_pinirq to kl_gpioirq to make it more generic to developers.
From Alan Carvalho de Assis (2014-12-13).
* arch/sim/src/up_ajoystick.c, Kconfig, Makefile, up_idle.c,
up_internal.h, up_x11eventloop.c, up_x11framebuffer.c,
configs/sim/src/Makefile, sim_boot.c, and traveler/defconfig: Add an
X11 mouse-based simulation of an analog joystick device (2014-12-14).
* drivers/sensors/adxl345*, include/nuttx/sensors/adxl345.h and other
files: Add driver support for the ADXL345 accelerometer. From Alan
Carvalho de Assis (2014-12-16).
* configs/freedom-kl25z: Add board support for the ADXL345 accelerometer.
From Alan Carvalho de Assis (2014-12-16).
* Kconfig, include/debug.h, drivers/sensors/*, and Qencoder logic in
arch/arm/src/stm32 and various QEncoder board support files under
config/: Unify sensor debug. ADX driver was using input debug; LM75
and QENCODE that their own custom debug. Now all use
CONFIG_DEBUG_SENSOR, sndbg() (2014-12-16).
* configs/dk-tm4c129x: Initial board support for the Tiva DK-TM4C129x
Connected Development Kit. The initial commit is just the Tiva
TM4C123G-Launchpad board support with naming changes (2014-12-16).
* include/nuttx/sched.h, sched/Kconfig, sched/init/os_start.c,
sched/pthread/pthread_create.c, sched/task/task_prctl.c,
sched/task/task_setup.c: strncpy() will not copy the terminating \0
into the destination if the source is larger than the size of the
destination. Ensure that the last byte is always zero and let strncpy
only copy CONFIG_TASK_NAME_SIZE bytes. The issue of unterminated names
can be observed in ps when creating a pthread while
CONFIG_TASK_NAME_SIZE is set to 8. From Daniel Willmann (2014-12-17).
* configs/*/*/defconfig: The previous change increased the task name
size allocation by one to hold a NUL terminator. This changes reduces
the configured name size by one so that no additional memory is used
(2014-12-17).
* drivers/wireless/cc3000/cc3000.c: CC3000 Fix: Data can be unaligned.
When dereferenced as an input ntosh(), a bad value is returned.
Reported by Alan Carvalho de Assis (2014-12-18).
* configs/freedom-kl25z: Update the Freedom KL25Z board CC3000 support
to use the current CC300 interfaces. From Alan Carvalho de Assis
(2014-12-18).
* arch/arm/src/tiva, include/tiva, and many configurations: Change
negative Tiva logic CONFIG_TIVA_DISABLE_GPIOx_IRQS to positive logic
CONFIG_TIVA_GPIOx_IRQ (2014-12-18).
* arch/arm/src/tiva/Kconfig: Fix configuration logic for IRQ interrupts.
The various parts support varying numbers of GPIO blocks and with varying
capabilities to support interrupts on the pins of different GPIO blocks
(2014-12-18).
* arch/arm/src/stm32/chip/stm32f40xxx_rcc.h: PLLSAI register name to
this one in the reference manual. From Marco Krahl (2014-12-19).
* arch/arm/src/stm32/chip/stm32_ltdc.h: Rename CFBLR register name to
the name used in the reference manual. From Marco Krahl (2014-12-19).
* arch/arm/src/stm32/chip/stm32_ltdc.h: Add missing clut register
* arch/arm/src/stm32/stm32f40xxx_rcc.c: Configure PLLSAI clock to
enable ltdc register access. From Marco Krahl (2014-12-19).
* configs/stm32f429i-disco/include/board.h: Update board definition for
the ili9341 LCD display. This configures all LCD settings for the RGB
interface. Also adds a customer LCD display template. From Marco Krahl
* arch/arm/src/stm32/stm32_ltdc.h: Define a common layer description for
the ltdc and dma2d controller. From Marco Krahl (2014-12-19).
* arch/arm/src/stm32/stm32_dma2d.c/.h and related files: Add
infrastructure for dma2d support. From Marco Krahl (2014-12-19).
* arch/arm/include/stm32/ltdc.h: Add interface to perform hardware
accelerated layer operation. The following methods must be supported
by the implementation: gevideoinfo, getplaneinfo, getlid, setclut,
getclut, setcolor, getcolor, setcolorkey, getcolorkey, setalpha,
getalpha, setblendmode, getblendmode, setarea, getarea, and update.
And if DMA2D is supported: blit and blend. The method up_ltdcgetlayer
provides access to a reference of a specific ltdc layer. From Marco
* arch/arm/src/stm32/stm32_ltdc.c: Implements ltdc frambuffer support
for the generic nuttx framebuffer interface, (see nuttx/video/fb.h).
This also implements the interface to perform hardware accelerated
layer operation by the ltdc controller and dma2d controller later
(see nuttx/video/ltdc.h). The following methods are supported by the
ltdc interface: getvideoinfo, getplaneinfo, getlid, setclut, getclut,
setcolor, getcolor, setcolorkey, getcolorkey, setalpha, getalpha,
setblendmode, getblendmode, setarea, getarea, and update. From Marco
* include/nuttx/lcd/ili9341.h: Update interface control definitions.
* configs/stm32f429i-disco/src/stm32_lcd.c: Add support for
initializing ltdc framebuffer and the configured lcd display. This
adds support for initializing of the ltdc controller and the lcd
device connected on the stm32f429i-disco. The following methods are
provided for the generic fb interface: up_fbinitialize,
up_fbgetvplane, and fb_uninitialize. The following methods are
provided for the ltdc interface: up_ltdcgetlayer. From Marco Krahl
* zrch/arm/src/stm32/Kconfig: Add configuration option for ltdc. This
adds the following ltdc configuration options: dither support, cmap
support, is this the right place for CONFIG_FB_CMAP?, support for
extended ltdc interface. From Marco Krahl (2014-12-19).
* nuttx/configs/stm32f429i-disco: Enable configuration of framebuffer
support for the ltdc controller. From Marco Krahl (2014-12-19).

* configs/stm32f429i-disco/ltdc: Add default platform configuration to
test framebuffer support for the ltdc. . From Marco Krahl
(2014-12-19).
* libnx/nxfonts/nxfonts_getfont.c: A patch to add previous added font
into nxf_getfonthandle function. From Pierre-Noel Bouteville
(2014-12-19).
* arch/arm/src/tiva, include/tiva, and many configurations: Change
negative Tiva logic CONFIG_SSIx_DISABLE to positive logic
CONFIG_TIVA_SSIx. Add support for SSI2 and SSI3 (2014-12-21).
* arch/arm/src/efm32/efm32_pwm.c/.h, efm32_timer.c/.h, and related
build files: Add support for timer/PWM on the EFM32GG. From
Pierre-noel Bouteville (2014-12-26).
* drivers/serial/Kconfig, serial.c, serialirq.c, and
include/nuttx/serial/serial.h: Add watermark levels to the serial
RX flow control logic. Modify the rxflowcontrol method to accept
the number of bytes in the buffer and a boolean indication of which
watermark was crossed (2014-12-27).
* sched/semaphore/sem_waitirq.c must be built when signals are disabled.
That is because not handles not only the case of semaphore wait
being awakened by a signal, but also the case with sem_timedwait.c
when the semaphore wait is awakened by a timeout (2014-12-28).
* arch/arm/src/stm32/stm32_ltdc.c: stm32: fix faulty access to non-
existing layer. This disables operation that requires double layer
support, when configured for single layer only. From Marco Krahl
(2014-12-29).
* arch/arm/src/stm32/stm32_ltdc.c: stm32: fix wait upon vertical blank.
This should never have occurred before. From Marco Krahl (2014-12-29).
* configs/stm32f429i-disco/ltdc/defconfig and src/stm32_boot.c:
stm32f429i-disco: change ltdc initializing during boot up. This moves
initializing of the ili9341 lcd and ltdc driver to the board specific
initializing routine. From Marco Krahl (2014-12-29).
* arch/arm/src/stm32/stm32_ltdc.c: Clean up documentation, some
formatting improvements. From Marco Krahl (2014-12-29).
* arch/arm/src/tiva/chip/tiva_ethernet.h, lm3s_ethernet.c, and
tm4c_ethernet.h: Add logic to discriminate betwen LM3S class Ethernet
register definitions and TM4C129X class Ethernet register definitions.
Add TM4C129X Ethernet register definitions (2014-12-30).
* arch/arm/src/tiva/tm4c_ethernet.c, lm3s_ethernet.c, Kconfig, and
Make.defs: First cut at TM4C129X Ethernet driver. Initial commit is
basically just the STM32 Ethernet driver with modifications for a clean
compilation in the Tiva environment (2014-12-31).
* arch/arm/src/stm32/stm32_rtc.c, stm32_rcc.c, Kconfig: Add support for
the internal low speed clock (LSI) as a source of the RTC clock. Some
boards do not have the external 32khz oscillator installed, for those
boards we must fallback to the crummy internal RC clock. Turn on by
defining CONFIG_RTC_LSICLOCK. From Kevin Hester (2015-01-02).
* net/tcp/tcp_conn.c: Fix a logic error when CONFIG_NETDEV_MULTINIC is
selected: net_unlock(flags) will be called will an uninitialized
variable (2015-01-03).
* arch/arm/src/tiva/tiva_irq.c: Fix Tiva IRQ control logic; was limited
to only 64 IRQs. That is a problem for higher numbered IRQs on many
platforms (2015-01-06).
* arch/arm/src/stm32/stm32_sdio.c, drivers/mmcsd/mmcsd_sdio.c and Kconfig,
and include/nuttx/sdio.h: MMCSD SDIO: Add support for a new
SDWAIT_WRCOMPLETE condition. The previous logic used a busy-wait loop
to poll the card R1 status to determine when the card was ready for
the next transfer. That busy-wait can be quite long -- up to hundreds
of milliseconds. An alternative is to look the the SD D0 pin which
will change state when the card is no longer busy. This change avoids
the busy-wait poll by reconfiguring the SD D0 pin as a GPIO interrupt,
then waiting for the card to become ready without taking up CPU
cycles. This change is conditioned on CONFIG_MMCSD_SDIOWATI_WRCOMPLETE
and is currently only implemented for the STM32 SDIO driver. From
David Sidrane (2015-01-08).
* arch/arm/src/tiva/tiva_timerlib.c and .h: Add a timer library for
* arch/arm/src/tiva/tiva_timerlow32.c: Add a driver lower half for
drivers/timer.c. Only 32-bit periodic timers are supported. This
provides userspace access to timers.
* configs/px4-v2_upstream, Kconfig, README.txt: Remove the px4-v2_upstream
configuration. Moved to misc/Obsoleted/configs. This was not the
official configuration for the PX4 board and has led to confusion by
NuttX users. The board configuration also requires some ongoing
maintenance and customization to support ongoing PX4 testing and
evaluation. It is best retained the PX4 repositories where it can be
properly maintained and not in the upstream NuttX repository
(2015-01-14).
* net/netdev/netdev_ioctl.c and include/nuttx/net/ioctl.h: Add support
for IPv6 ioctls to manipulate IP addresses (2015-01-14).
* net/icmpv6: Create a future home for ICMPv6 (2015-01-14).
* net/icmp: Remove all logic conditioned on CONFIG_NET_IPv6
(2015-01-14).
* net/, include/nuttx/net, and a few other files: (1) Copied all ICMP
sources files to net/icmpv6 with proper renaming and removal of IPv4
logic, (2) remove IPv6 logic from files in net/icmp, (3) copied
include/nuttx/icmp.h to icmpv6.h and removed IPv4 specific logic, (4)
removed all IPv6 logic from icmp.h, (5) IP_HDRLEN became IPv4_HDRLEN
and IPv6_HDRLEN, (6) ip_chksum() became ipv4_chksum() and
ipv6_chksum(), and (7) added partial support for ICMPv6 statistics
(2015-01-14).
* arch/, drivers/net/, include/nuttx/net, and net/devif: (1) Rename
devif_input() ipv4_input(), (2) copy net/devif/devif_input.c to
ipv6_input.c, remove all IPv4-specific logic, (3) rename
net/devif/devif_input.c to ipv4_input.c, remove all IPv6-specific
logic, and (4) xplit IPv4 header structure out as net_ipv4hdr_s from
net_iphdr_s (2015-01-15).
* arch/ and drivers/net: All Ethernet drivers: Call ipv6_input() if
IPv6 is enabled and an IPv6 packet is received (2015-01-15).
* net/devif, net/tcp, net/ucp, include/nuttx/net: Separate tcp_input()
and udp_input() into seprate functions tcp_ipv4_input(),
tcp_ipv6_input(), udp_ipv4_input(), and upd_ipv6_input() than can deal
will the data offsets caused by the differing sizes of the IP header
(2015-01-15).
* net/utils/net_ipv6_maskcmp.c: Add missing implementation of
net_ipv6_maskcmp() (2015-01-15).
* Networking: Drivers can have both IPv4 and IPv6 addresses, but a
socket can only only one or the other; The socket connection
structures need to include a union of IPv4 and IPv6 addresses for
the local address binding and for the remote address connections
(2015-01-16).
* Networking: Replace all references to net_ipaddr_t with either
in_addr_t on net_ipv6addr_t. The goal is to support both IPv4 and
IPv6 simultaneously. This requires that the two types be distinct
and not conditionally typedef'ed to net_ipaddr_t (2015-01-16).
* Networking: Replace all references to the macros net_ipaddr_copy,
net_ipaddr_hdrcopy, net_ipaddr_cmp, net_ipaddr_hdrcmp, and
net_ipaddr_maskcmp with the appropriate IPv4 or IPv6 version of the
macro (such as net_ipv4addr_copy). The goal is to support both
IPv4 and IPv6 simultaneously. This requires that the macros be
distinct and not conditionally defined to one on or the other
(2015-01-16).
* Networking: UDP and TCP MSS depends on the IP header size (as well
as the link layer header size) and cannot be represented with a
single value (2015-01-16).
* net/neighbor: Move net/ipv6 to net/neighbor (2015-01-16).
* include/net/if.h: Add a bit to the device flags to indicate if the
device packet buffer holds an IPv4 or an IPv6 domain packet.
Set/clear the flag along with the correct offset to the application
payload data as each packet is received (2015-01-17).
* net/socket, net/tcp, net/udp: Add logic to select the domain of the
outgoing packet before sending any UDP or TCP packet. This sets the
bit to indicate the IPv4 or IPv6 domain and the correct offset to the
output going payload data (2015-01-17).
* net/socket and net/tcp: When we are ready to receive data or when we
have outgoing data ready to be sent, we need to the notify the
appropriate device driver of this condition. The notifying socket
will be configured as either PF_INET or PF_INET6 and must look up the
correct driver using the correct IP domain (2015-01-17).
* net/socket/accept.c: Fix accept() so that it returns the correct IP
address for the selected socket IP domain (2015-01-17).
* Networking: Final detangling off IPv4 and IPv6 TCP/UDP send logic.
The networking subsystem now compiles with IPv6 enabled (2015-01-18).
* arch/arm/src/tiva/tm4c_ethernet.c: When calling into the stack
from the worker thread, it is necessary to have the stack locked
(2015-01-18).
* nuttx/arch/arm/src/stm32/stm32_serial.c: fix declaration and
definition of up_receive() and up_dma_receive() to match fields of
uart_ops_s from nuttx/include/nuttx/serial/serial.h. From Freddie
Chopin (2015-01-19).
* drivers/pipes/pipe.c, drivers/usbdev/cdcacm.c, and
mm/mm_gran/mm_granalloc.c: Fixes some issues found by the PX4 team
using Coverity. From Pavel Krienko (2015-01-19).
* net/icmpv6/icmpv6_solicit.c, net/neighbor/neighbor_out.c, and other
files: Add logic to search the Neighbor Table and update the
destination address in the output Ethernet header OR to send an
ICMPv6 Neighbor Solicitation if there is no entry in the Neighbor
table for the IPv6 address (2015-01-20).
* arch/ and drivers/net: Add missing raw/packet socket support toi
all Ethernet driverss (2015-01-20).
* arch/ and drivers/net: "Networking: Modify all Ethernet drivers:
Do neighbor look-up on all outgoing IPv6 packs in order to properly
set the destination link layer address (2015-01-20).
* Networking: When sending ICMPv6 advertisements and solicitations,
set the NOARP bit so that we don't overwrite the destination MAC
address (2015-01-20).
* Many files: Correct name of fields in struct sockaddr_in6: sin6_port
and sin6_family, not sin_port and sin_family (2015-01-20).
* net/socket/accept.c: Correct the value returned by accept() in the
case where net_lockingwait() is called. It was returning -1 and
losing the errno value. Noted by Rony Xln (2015-01-22).
* net/: After some significant effort, ICMPv6 and TCP are both
functional when IPv6 is selected. UDP still requies testing
* configs/dk-tm4c129x/ipv6: Add an IPv6-enabled NSH configruation
* include/nuttx/net/icmpv6.h and net/icmpv6/icmpv6_ping.c: First cut
at ICMPv6 ping logic. It works in both directions! (2015-01-23).
* arch/arm/src/efm32/efm32_rmu.c and .h: Add support for the EFM32
reset management unit (RMU). From Pierre-noel Bouteville
(2015-01-23).
* include/nuttx/math.h: Adds support for the expm1 functions:
http://pubs.opengroup.org/onlinepubs/009695399/functions/expm1.html.
From Brennan Ashton (2015-01-23).
* Many file: Add CONFIG_STACK_COLORATION that does the same thing as
CONFIG_DEBUG_STACK but without enabling debug. From David Sidrane
(2015-01-24).
