It is possible that a context switch + occurs after I2C registers are read but before elapsed time is saved + in stm32_i2c_sem_waitstop(). It is then possible that the registers + were read only once with "elapsed time" equal 0. When scheduler + resumes this thread it is quite possible that now "elapsed time" will + be well above timeout threshold. In that case the function returns + and reports a timeout, even though the registers were not read + "recently".

The call + to sem_restorebaseprio() must be one of the last things the + sem_wait() does because it can cause the task to be suspended.

The call to + sem_restorebaseprio_task context switches in the + sem_foreachholder(sem, sem_restoreholderprioB, stcb); call prior to + releasing the holder. So the running task is left as a holder as is + the started task. Leaving both slots filled thus failing to perform + the boost/or restoration on the correct tcb. This PR fixes this by + releasing the running task slot prior to reprioritization that can + lead to the context switch. To faclitate this, the interface to + sem_restorebaseprio needed to take the tcb from the holder prior to + the holder being freed. In the failure case where sched_verifytcb + fails it added the overhead of looking up the holder. There is also + the additional thunking on the foreach to get from holer to + holder->tcb. An alternate approach could be to leve the interface + the same and allocate a holder on the stack of sem_restoreholderprioB + copy the sem's holder to it, free it as is done in this pr and and + then pass that address sem_restoreholderprio as the holder. It could + then get the holder's tcb but we would keep the same sem_findholder + in sched_verifytcb. From David Sidrane (2017-03-15). + * ARM: Remove redundant interrupt stack coloring.

This was a consequence of + the recent robust mutex changes. If robust mutexes are selected, + then each mutex that a thread takes is retained in a list in threads + TCB. If the thread exits and that list is not empty, then we know + that the thread exitted while holding mutexes. And, in that case, + each will be marked as inconsistent and the any waiter for the thread + is awakened. For the case of pthread_mutex_trywait(), the mutex was + not being added to the list! while not usually a fatal error, this + was caught by an assertion when pthread_mutex_unlock() was called: + It tried to remove the mutex from the TCB list and it was not there + when, of course, it shoule be. The fix was to add + pthread_mutex_trytake() which does sem_trywait() and if successful, + does correctly add the mutext to the TCB list.

From Jussi Kivilinna (2017-04-06). + * sim/sixlowpan: Now supports apps/examples/udpblaster too (2017-04-06). + * SAMV7: Watchdog: Fix Forbidden Window Value. According the Datasheet + the WDD Value is the lower bound of a so called Forbidden Window and + to disable this we have to set the WDD Value greater than or equal to + the WDV Value.

From + Juha Niskanen (2017-05-12). + * syslog: Avoid flushing syslog_stream buffer, if possible, until + lib_vsprintf() completely parses the format. This assures that the + flush will flush the entire output, even data that may potentially + follow the linefeed. And, in that case, it cannot be interleaved + with other devug output. Suggested by Jussi Kivilinna (2017-05-12). + * syslog: There is yet another place where the output can get split. + That is in syslog_dev_write(): It will break up the stream to insert + a CR before the LF. This can that can be avoid be generating the + CR-LF sequence in the buffer and then detecting and ignoring valid + CR-LF sequences, rather than expecting syslog_dev_write() to insert + the CR in this case. I don't like the idea that syslog_dev_write() + still scans the entire output buffer to expand CR-LF sequence. This + seems really wasteful, especially in this case where we can be sure + that the is no CR or LF without a matching LF or CR.

From Juha Niskanen (2017-05-15). + * drivers: rename newly introduced up_i2creset to I2C_RESET. From + Juha Niskanen (2017-05-15). + * TCP: An RST received during the 3-way handshake requires a little + more clean-up (2017-05-15). + * STM32 CAN: I had the problem that the transmit FIFO size (= actual + elements in FIFO) was slowly increasing over time, and was full after + a few hours. The reason was that the code hit the line + "canerr("ERROR: No available mailbox\n");" in stm32_cansend, so + can_xmit thinks it has sent the packet to the hardware, but actually + has not. Therefore the transmit interrupt never happens which would + call can_txdone, and so the size of the FIFO size does not decrease. + The reason why the code actually hit the mentioned line above, is + because stm32can_txready uses a different (incomplete) condition than + stm32can_send to determine if the mailbox can be used for sending, + and thus can_xmit forwards the packet to stm32can_send. + stm32can_txready considered mailboxes OK for sending if the mailbox + was empty, but did not consider that mailboxes may not yet be used if + the request completed bit is set - stm32can_txinterrupt has to + process these mailboxes first. Note that I have also modified + stm32can_txinterrupt - I removed the if condition, because the CAN + controller retries to send the packet until it succeeds. Also if the + condition would not evaluate to true, can_txdone would not be called + and the FIFO size would not decrease also. From Lederhilger Martin + (2017-05-16). + * drivers/bch: BCH character driver bch_ioctl() always returns -ENOTTY + for DIOC_GETPRIV command. It should returns OK if DIOC_GETPRIV + command succeeds. From EunBong Song (2017-05-16). + * There can be a failure in IOB allocation to some asynchronous + behavior caused by the use of sem_post(). Consider this scenario: + (1) Task A holds an IOB.  There are no further IOBs.  The value of + semcount is zero. Task B calls iob_alloc().  Since there are not + IOBs, it calls sem_wait().  The value of semcount is now -1. (2) + Task A frees the IOB.  iob_free() adds the IOB to the free list and + calls sem_post() this makes Task B ready to run and sets semcount to + zero NOT 1.  There is one IOB in the free list and semcount is zero. + When Task B wakes up it would increment the sem_count back to the + correct value. (3) But an interrupt or another task runs occurs + before Task B executes.  The interrupt or other tak takes the IOB off + of the free list and decrements the semcount.  But since semcount is + then < 0, this causes the assertion because that is an invalid state + in the interrupt handler. So I think that the root cause is that + there the asynchrony between incrementing the semcount. This change + separates the list of IOBs: Currently there is only a free list of + IOBs. The problem, I believe, is because of asynchronies due + sem_post() post cause the semcount and the list content to become out + of sync. This change adds a new 'committed' list: When there is a + task waiting for an IOB, it will go into the committed list rather + than the free list before the semaphore is posted. On the waiting + side, when awakened from the semaphore wait, it will expect to find + its IOB in the committed list, rather than free list. In this way, + the content of the free list and the value of the semaphore count + always remain in sync (2017-05-16). + * stm32_serial: Fix freezing serial port. Serial interrupt + enable/disable functions do not disable interrupts and can freeze + device when serial interrupt is received while execution is at those + functions. Trivially triggered with two or more threads write to + regular syslog stream and to emergency stream. In this case, freeze + happens because of mismatch of priv->ie (TXEIE == 0) and actually + enabled interrupts in USART registers (TXEIE == 1), which leads to + unhandled TXE interrupt and causes interrupt storm for USART. From + Jussi Kivilinna (2017-05-17). + * STM32 Ethernet: Add support for KSZ8081 PHY interrupts. From + Sebastien Lorquet (2017-05-17). + * IPv6: Fix net_ipv6_pref2mask().

Note +that release consists of two tarballs: nuttx-7.21.tar.gz and +apps-7.21.tar.gz. These are available from: + + https://bitbucket.org/nuttx/nuttx/downloads + https://bitbucket.org/nuttx/apps/downloads + +Both may be needed (see the top-level nuttx/README.txt file for build +information). + +Additional new features and extended functionality: + + * Core OS: + + - pthread rwlocks: Add an implementation for read/write locks + (rwlocks) into the pthread library. These locks are writer + priority, such that if any writers come in they are given priority + for writing. From Mark Schulte. + - pthread robust mutexes: Implement robust mutex support: + pthread_mutex_lock() and trylock() will return EOWNERDEAD if the + mutex is locked by a thread that no longer exists. Add + pthread_mutex_consistent() to recover from this situation. Keep + list of all mutexes held by a thread in a list in the pthread's TCB. + When pthread exits or is cancelled, mutexes held by thread are + marked inconsistent and the highest priority thread waiting for the + mutex is awakened. There is a configuration option to (a) support + only robust mutexes, (b) support only traditional unsafe mutexes, + or (c) Support both unsafe and robust mutexes via + pthread_mutexattr_get/setrobust(). + - pthread cancellation points: Add logic to disable cancellation + points within the OS. This is useful when an internal OS function + that is NOT a cancellation point calls an OS function which is a + cancellation point. In that case, irrecoverable states may occur if + the cancellation is within the OS. From Juha Niskanen. + - clock: Add clock_resynchronize and use subseconds RTC. Add + clock_resynchronize for better synchronization of CLOCK_REALTIME and + CLOCK_MONOTONIC to match RTC after resume from low-power state. Add + up_rtc_getdatetime_with_subseconds under + CONFIG_ARCH_HAVE_RTC_SUBSECONDS to allow initializing (and + resynchronizing) system clock with subseconds accuracy RTC. From + Jussi Kivilinna. + - clock: Add new type ssystime_t for relative 64-bit ticks, change + ticks<->time conversion functions to use ssystime_t. From Jussi + Kivilinna. + - clock: Add testing for 32-bit overflow of 64-bit system timer. From + Jussi Kivilinna. + + * File Systems/Block and MTD Drivers + + - drivers/mtd/w25.c: Erase sector only if it is not in erased state. + From Jussi Kivilinna. + + * Graphics/Display Drivers: + + - drivers/lcd: Extend st7565 driver to include support for the + AQM_1248A. From Masayuki Ishikawa. + - drivers/lcd: Add driver for Nokia 5110 (Philips PCD8544). From Alan + Carvalho de Assis. + + * Networking/Network Drivers: + + - Extensive modifications to support wireless network (see below). + - TUN driver: Implement TAP (OSI layer 2) mode. Enable by setting the + IFF_TAP flag instead of the IFF_TUN flag in ifr_flags. From Thomas + Keh. + - Add user-space networking stack API (usrsock). User-space + networking stack API allows user-space daemon to provide TCP/IP + stack implementation for NuttX network. Main use for this is to + allow use and seamless integration of HW-provided TCP/IP stacks to + NuttX. For example, user-space daemon can translate /dev/usrsock + API requests to HW TCP/IP API requests while rest of the user-space + can access standard socket API, with socket descriptors that can be + used with NuttX system calls. From Jussi Kivilinna. + - net/: Network driver now retains Ethernet MAC address in a union so + that other link layer addresses may be used in a MULTILINK + environment. + + * Wireless Networking/Wireless Drivers: + + - BCM43362: Support for Broadcom's BCM43362 WiFi chip was contributed + by Simon Piriou as part of the port of the Particle Photon board. + Only station functionality is available at present. This work + includes not on the WiFi driver, but the support Particle Photon + board, the infrasture for IEEE 802.11 FullMAC networking including + the network device interface, WiFi configuration, AP scanning and + authentication and association with an AP. + - IEEE 802.11 networking tools and support. + - IEEE 802.15.4 MAC support. This is an effort that was started some + time back by Sebastien Lorquet (with some help from Matte Poppe). + Recently, Anthony Merlino has taken on this effort and has made + some significant progress. Using the Microchip MRF24J40 module with + the Mikroe Clicker2-STM32 board along with a PC-based IEEE 802.15.4 + sniffer, Anthonly has verified correct transmittion and receipt of + basic frames. + - Microchip MRF24J40: As mentioned above, this IEEE 802.15.4 radio + driver is now basically functional. + - IEEE 802.15.4 Network Driver: A driver that interfaces the NuttX + network with the IEEE 802.15.4 MAC has been developed but is still + incomplete and has not been verified. + - IEEE 802.15.4 Network Loopback Driver: A simple IEEE 802.15.4 MAC + loopback driver was developed. This driver allowed for parallel + development of the IEEE 802.15.4 MAC and 6loWPAN. + - 6loWPAN: The Contiki 6loWPAN stack has been ported so that works + within the NuttX networking framework and interfaces with the new + IEEE 802.15.4 MAC via the network driver. Live testing with + IEEE 802.15.4 radios has not yet been done; all testing has used + the loopback driver. There are no known problems and the stack + is ready for additional testing. + - Add option to enable wireless debug output. + + * Other Common Device Drivers: + + - Add entropy pool and strong random number generator. Entropy pool + gathers environmental noise from device drivers, user-space, etc., + and returns good random numbers, suitable for cryptographic use. + Based on entropy pool design from *BSDs and uses BLAKE2Xs algorithm + for CSPRNG output. Patch also adds /dev/urandom support for using + entropy pool RNG and new 'getrandom' system call for getting + randomness without file-descriptor usage (thus avoiding file- + descriptor exhaustion attacks). The 'getrandom' interface is similar + as 'getentropy' and 'getrandom' available on OpenBSD and Linux + respectively. From Jussi Kivilinna. + - XBox One controller: Adds USB host driver support for the XBox One + controller. Currently only the latest version (XBox One X) + controller works. The older XBox One controllers do not enumerate + correctly. From Brian Webb. + - drivers/analog: Add basic COMP driver. From Mateusz Szafoni. + - drivers/analog: Add driver for the LTC1767L ADC. From Martin + Lederhilger. + - drivers/analog: Add basic OPAMP driver. From Mateusz Szafoni. + - drivers/sensors: Add driver for ST HTS221 humidity sensor. From + Juha Niskanen. + - drivers/sensors: Add driver for ST LPS25H pressure sensor. From + Juha Niskanen. + - drivers/sensors: Add driver for ST LIS2DH accelerometer. From Timo + Voutilainen. + - drivers/usbmisc: Add driver for Fairchild FUSB301 USB type-C + controller. From Harri Luhtala. + - RTC: Add interface for check if RTC time has been set. New + interface allows checking if RTC time has been set. This allows to + application to detect if RTC has valid time (after reset) or should + application attempt to get real time by other means (for example, by + launching ntpclient or GPS). From Jussi Kivilinna. + - Buttons: Change return value of board_buttons() and the type of + btn_buttonset_t to uint32_t so that more than 8 buttons can be + supported. + - drivers/syslog: Use monotonic clock for timestamp when available. + From Jussi Kivilinna. + - SPI: Add an instance argument to the SPIDEV definitions. Thus, + instead of specifying a FLASH device, for example, as SPI_FLASH, you + would now use SPI_FLASH(0) where the "instance" argument now + distinguishes multiple FLASH devices on the same SPI bus. From + Sebastien Lorquet. + - IOBs: Move from net/iob to a better location in mm/iob where they + can be shared outside of the networking logic. Current also used + by IEEE 802.15.4 MAC and by syslog (when buffering enabled). + - syslog: Add option to buffer SYSLOG output to avoid interleaving. + Uses new shareable IOBs. Additional logic to assure that the the + write from the buffer is a single atomic write in normal debug + output. + - drivers/can: Move CAN subsystem to its own directory and put device + drivers there. From Alan Carvalho de Assis. + - drivers/can: Add Microchip MCP2515 CAN Bus controller driver. From + Alan Carvalho de Assis. + - drivers/audio: Add cs43l22 audio driver. From Taras Drozdovsky. + - drivers/input: Add Cypress MBR3108 CapSense touch button driver. + From Juha Niskanen. + + * Simulation + + - configs/sim/sixlowpan: Configuration for testing the 6loWPAN with + the IEEE 802.15.4 loopback network driver. + + * Infineon XMC4xxx: + + - arch/arm/src/xmc4: Initial, partial support for Infineon XMC4xxx. + + * Infineon XMC4xxx Boards: + + - XMC4500 Relax: Add basic board support infrastructure of Infineon + XMC4500 Relax Lite v1. Basic serial, LED, and button button support + for a simple NSH configuration. There are still stome remaining + issues with serial communications. + + * MicroChip PIC32MX Boards: + + - pic32mx7mmb: Add support for the Pinquino toolchain. + - pic32mx7mmb: Add support for PROCFS file system. + + * NXP Freescale Kinetis: + + - Kinetis: Allow board to add pullups on SDHC lines. From David + Sidrane. + - Kinetis: Use optional BOARD_OSC_CR and BOARD_OSC_DIV in clock + configuration. From David Sidrane. + + * NXP Freescale Kinetis Drivers: + + - Kinetis: Add Timer PWM Module (TPM) to K66 chip. From David + Sidrane. + - Kinetis: Added HW flow control and termios. From David Sidrane. + - Kinetis: Add ARCH_HAVE_I2CRESET. From David Sidrane. + + * NXP Freescale LPC43xx: + + - Add support for LPC4337FET256. From Andreas Bihlmaier. + + * STMicro STM32: + + - Change STM32 tickless to use only one timer. From Konstantin + Berezenko. + - STM32 F7: Add support for LSE RTC and enable RTC subseconds. From + Jussi Kivilinna. + - STM32 L1: stm32l15xx_rcc: Add support for using MSI as system + clock. From Juha Niskanen. + - STM32 L1: stm32l15xxx_rcc: configure medium performance voltage + range and zero wait-state when allowed by SYSCLK setting. Zero + wait-state for flash can be configured when: (1) Range 1 and + SYSCLK <= 16 Mhz, (2) Range 2 and SYSCLK <= 8 Mhz, or (3) Range 3 + and SYSCLK <= 4.2 Mhz. Medium performance voltage range (1.5V) + can be configured when SYSCLK is up to 16 Mhz and PLLVCO up to + 48 Mhz. From Juha Niskanen. + - STM32 F0: Add basic support for STM32F0. From Alan Carvalho de + Assis. + - STM32 F0: Add basic support for STM32F07x family. + - STM32 L1: stm32l15xx_rcc: Allow board to configure HSE clock in + bypass-mode. Allows using MCO output from ST-link chip (on Nucleo + and Discovery boards) as HSE input.

From Juha + Niskanen. + - STM32 L4: modularize Kconfig to support different product + lines/families. This is modeled after STM32F7. Idea is to declare + each chip in Kconfig but allow for flash size override. Commit adds + many STM32L4_HAVE_XXX feature test macros. From Juha Niskanen. + - STM32 L4: Separate SYSCFG into product line specific files for + clarity. From Juha Niskanen. + - STM32 L4: Add support for many new MCUs from the STM32L4X3XX + product line. From Juha Niskanen. + - STM32 L4: Add dbgmcu header files. From Juha Niskanen. + - STM32 F410: Add support for STM32F410. STM32F410 is a version of + STM32F4 with 32 KB of RAM and 62 or 128 KB of flash. From Gwenhael + Goavec-Merou. + + * STMicro STM32 Drivers: + + - SDIO: Extensions to support the SDIO interface to the BCM43362 from + Simon Piriou. + - STM32 F2: Add USB OTG HS support for stm32f20xxx cores.

This is in addition to the + CPU-specific versions of the same definition. + - Move prototype for up_cxxinitialize() from nuttx/include/nuttx/arch.h + to apps/include/platform/cxxinitialize.h. + + * Tools: + + - Add initialconfig.c so that perhaps in the future we will be able to + use this to generate a new configuration from scratch (rather than + having to derive new configurations from existing configurations). + NOTE: Not yet intregated into the build system. + + * NSH: apps/nshlib: + + - Added support for set [{+|-}{e|x|xe|ex}] [ ]. Set the + 'exit on error control' and/or 'print a trace' of commands when + parsing scripts in NSH. The settinngs are in effect from the point + of exection, until they are changed again, or in the case of the init + script, the settings are returned to the default settings when it + exits. Included child scripts will run with the parents settings and + changes made in the child script will effect the parent on return. + Use 'set -e' to enable and 'set +e' to disable (ignore) the exit + condition on commands. The default is -e. Errors cause script to + exit. Use 'set -x' to enable and 'set +x' to disable (silence) + printing a trace of the script commands as they are ececuted. The + default is +x. No printing of a trace of script commands as they are + executed. From David Sidrane. + - Print expanded variables if -x. From David Sidrane. + - ifconfig command: Extend ifconfig to support 6loWPAN. Adapt to + some changes in configuration variable usage. + - Network initialization: If IEEE802.11 selected use wlan0 instead of + eth0 for network device name. + - Network initialization: NSH now has configuration options to select + the wireless properties. It builds the configuration structure and + passes this to wpa_driver_wext_associate() so that it will set the + network as configured. + - Network initialization: Add a new option CONFIG_NSH_NETLOCAL that + will suppress some built in operations and will support manual + configuration of a wireless network through command line tools. + + * Examples/Tests: apps/examples: + + - examples/xbc_text: Adds a test program for the XBox One controller + driver. From Brian Webb. + - examples/ostest: Add a test of robust mutexes. + - examples/ostest: Add tests for pthread_rwlock. Adding tests to be + used to verify the pthread_rwlock lock works. From Mark Schulte. + - examples/ostest: Additional test for rwlock and one for cancel + cleanup handlers. From Juha Niskanen. + - examples/usrsocktest: Add application for USRSOCK testing. From + Jussi Kivilinna. + - examples/nettest: Adapt for use in testing 6loWPAN. + - examples/nettest: If doing loopback, but not using the official + loopback device, then use the server should use the configured client + IP address. + - examples/udpblaster: Several fixes to work with 6loWPAN. + - examples/udpblaster: Add logic to bind the local UDP socket to a + well-known address. + - examples/configdata: Add stacksize and priority. From Juha Niskanen. + + * Network Utilies: apps/netuils: + + - netutils/netlib: Add IEEE 802.11 wireless IOCTL wrappers. + - netutils/netlib: Add a helper function to convert a string to a + 6loWPAN node address. + - netlib and NSH: Add logic to get/set the IEEE802.15.4 PAN ID. + - netutils/dhcpc: Make the network device name a configuration + option. Was hardcoded to eth0 but may, instead, need to be wlan0. + - netutils/dhcpc: Remove hard-coded interface device. Now passed as + a parameter to dhcpc_open(). From Sebastien Lorquet. + + * Wireless Utilies: apps/wireless: + + - wireless/wapi: Port of Wapi wireless services. The original + depended on features not supported by NuttX: Removed logic that + depends on Linux netlink. Removed functionality that depended on + the Linux procfs: This includes only 1) listing of available + interfaces and 2) listing of all routes. + - wireless/wapi: Create command line Wapi application based on + Wapi sample code. + - wireless/wapi: wpa_driver_wext_associate() now accepts a + configuration parameter that can be used to specify the wireless + properties. + - wireless/wapi: Add basic wapi_event_stream_extract implementation. + From Simon Piriou. + - wireless/ieee802154: Add iwpan and i8sak tools. iwpan is similar + in concept to wapi. From Anthony Merlino (i8sak was originally + by Sebastien Lorquet). + - wireless/ieee802154/libmac: IEEE 802.15.4 MAC library. + - wireless/wext: Add drivers_wext from the WPA supplicant; Integrate + into NSH. From Simon Piriou. + + * System Unitilities (apps/system) + + - apps/system/dhcpc: Add a command to renew or establish a lease on an + IPv4 address. + - apps/system/ntpc: Add a command to start or stop the NTPC daemon. + - apps/system/ramtest: Make stacksize and priority conigurable. + + * Platform-Specific Support (apps/platform) + + - apps/platform: Create gnu/ subdirectory that contains the one and + only GNU C++ initialization function. Remove all other C++ + initialization functions. + +Bugfixes. Only the most critical bugfixes are listed here (see the +ChangeLog for the complete list of bugfixes and for additional, more +detailed bugfix information): + + * Core OS: + + - Priority inheritance: When CONFIG_SEM_PREALLOCHOLDERS==0, there is + only a single, hard-allocated holder structure. This is problem + because in sem_wait() the holder is released, but needs to remain in + the holder container until sem_restorebaseprio() is called. The call + to sem_restorebaseprio() must be one of the last things the + sem_wait() does because it can cause the task to be suspended. If in + sem_wait(), a new task gets the semaphore count then it will fail to + allocate the holder and will not participate in priority + inheritance. This fix is to add two hard-allocated holders in the + sem_t structure: One of the old holder and one for the new holder. + - Priority inheritance: sem_holder sem_findholder missing + inintalization of pholder. sem_findholder would fail and code + optimization covered this up. From David Sidrane. + - Partial Fix priority inheritance CONFIG_SEM_PREALLOCHOLDERS=0. From + David Sidrane. + - Priority inheritance: sem_boostholderprio prevent overrun of + pend_reprios. The second case rtcb->sched_priority <= + htcb->sched_priority did not check if there is sufficient space in + the pend_reprios array. From David Sidrane. + - lp_worker: Guard from pend_reprios overlow. From David Sidrane. + - Priority inheritance: Fixes improper restoration of base_priority in + the case of CONFIG_SEM_PREALLOCHOLDERS=0. The call to + sem_restorebaseprio_task context switches in the + sem_foreachholder(sem, sem_restoreholderprioB, stcb); call prior to + releasing the holder. So the running task is left as a holder as is + the started task. Leaving both slots filled thus failing to perform + the boost/or restoration on the correct tcb. This PR fixes this by + releasing the running task slot prior to reprioritization that can + lead to the context switch. To faclitate this, the interface to + sem_restorebaseprio needed to take the tcb from the holder prior to + the holder being freed. In the failure case where sched_verifytcb + fails it added the overhead of looking up the holder. There is also + the additional thunking on the foreach to get from holer to + holder->tcb. An alternate approach could be to leve the interface + the same and allocate a holder on the stack of sem_restoreholderprioB + copy the sem's holder to it, free it as is done in this pr and and + then pass that address sem_restoreholderprio as the holder. It could + then get the holder's tcb but we would keep the same sem_findholder + in sched_verifytcb.

From Masayuki Ishikawa. + - binfmt/elf: Fix offset value when calling elf_read() in + elf_sectname(). From Masayuki Ishikawa. + - There can be a failure in IOB allocation to some asynchronous + behavior caused by the use of sem_post(). Consider this scenario: + (1) Task A holds an IOB.  There are no further IOBs.  The value of + semcount is zero. Task B calls iob_alloc().  Since there are not + IOBs, it calls sem_wait().  The value of semcount is now -1. (2) + Task A frees the IOB.  iob_free() adds the IOB to the free list and + calls sem_post() this makes Task B ready to run and sets semcount to + zero NOT 1.  There is one IOB in the free list and semcount is zero. + When Task B wakes up it would increment the sem_count back to the + correct value. (3) But an interrupt or another task runs occurs + before Task B executes.  The interrupt or other tak takes the IOB off + of the free list and decrements the semcount.  But since semcount is + then < 0, this causes the assertion because that is an invalid state + in the interrupt handler. So I think that the root cause is that + there the asynchrony between incrementing the semcount. This change + separates the list of IOBs: Currently there is only a free list of + IOBs. The problem, I believe, is because of asynchronies due + sem_post() post cause the semcount and the list content to become out + of sync. This change adds a new 'committed' list: When there is a + task waiting for an IOB, it will go into the committed list rather + than the free list before the semaphore is posted. On the waiting + side, when awakened from the semaphore wait, it will expect to find + its IOB in the committed list, rather than free list. In this way, + the content of the free list and the value of the semaphore count + always remain in sync. + - binfmt: Fix .dtor memory allocation.

From David + Sidrane. + - STM32 CAN: I had the problem that the transmit FIFO size (= actual + elements in FIFO) was slowly increasing over time, and was full after + a few hours. The reason was that the code hit the line + "canerr("ERROR: No available mailbox\n");" in stm32_cansend, so + can_xmit thinks it has sent the packet to the hardware, but actually + has not. Therefore the transmit interrupt never happens which would + call can_txdone, and so the size of the FIFO size does not decrease. + The reason why the code actually hit the mentioned line above, is + because stm32can_txready uses a different (incomplete) condition than + stm32can_send to determine if the mailbox can be used for sending, + and thus can_xmit forwards the packet to stm32can_send. + stm32can_txready considered mailboxes OK for sending if the mailbox + was empty, but did not consider that mailboxes may not yet be used if + the request completed bit is set - stm32can_txinterrupt has to + process these mailboxes first. Note that I have also modified + stm32can_txinterrupt - I removed the if condition, because the CAN + controller retries to send the packet until it succeeds. Also if the + condition would not evaluate to true, can_txdone would not be called + and the FIFO size would not decrease also. From Lederhilger Martin. + - STM32 Serial: Fix freezing serial port.
