It was just a simple + wrapper around kill() but since the correct dispatching of signals + for multi-threaded task groups has been implemented, calling kill() + does not do what pthread_kill() is supposed to do. The corrected + implementation of pthread_kill() will direct the signal specifically + to the specific pthread and no other. + - uint32_t callbacks: Update the type passed to watchdog timer + handlers. Using uint32_t is a problem for 64-bit machines because + it it too small to pass a pointer. uintptr_t is a more appropriate + type. + - mq_timedreceive(): move the location where the errno value is set; + the ETIMEDOUT errno setting was being overwritten by subsequent + actions before returning. Noted by Freddie Chopin. + - POSIX message queues: Move mq_setattr() and mq_getattr() from + nuttx/libc/mqueue to nuttx/sched/mqueue. Also add syscall support + for mq_setattr() and mq_getattr(). This is necessary in protected + and kernel builds because in those cases the message queue + structure is protected and cannot be accessed directly from user + mode code. Noted by Jouko Holopainen. + + * File Systems/Block Drivers/MTD: + + - MTD: Increase the size of the fields in the geometry structure + (again) to support larger FLASH sizes. Needed by Sebastien Lorquet. + + * Common Drivers: + + - poll(): Fix resource leak and memory corruption on poll failure. + From Jussi Kivilinna. + + * USB Host: + + - LPC31xx and SAMA5Dx EHCI: Fix cache related problem in LPC31 and + SAMA5Dx EHCI drivers. All buffers are now aligned with the cache + line size in both starting address and in length. This cause major + problems in unlucky builds where the USB host buffers where + unaligned and abutting other data. The cache flush and invalidate + operations could be subverted by accesses to adjacent data or could + have unexpected side effects. This bug has been in the ECHI drivers + forever, but was only revealed due to unlucky memory allocations + during the integration of the hub feature. + + * USB Device: + + - All USB device class drivers: There needs to be a check to make + sure that the size of a returned string does not exceed the size of + the allocated request buffer. Strings such as vendor names or + product names will be truncated to fit in the request buffer. + + * Networking: + + - TCP: Correct failures in long Telnet sessions by increasing th + size of the number of bytes sent from uint16_t to uint32_t. This + avoids an integer overflow that causes a long Telnet session to be + closed unexpectedly. From Rony XLN. + - Network locks: Correct some network lock logic: Two error + conditions where the network was not being unlocked and one where it + was getting unlocked twice. From Jussi Kivilinna. + - Local Sockets: Local stream sockets had problem of double releasing + pipes (both server and client attempt release), which causes wrong + pipe pair being closed in multi-client case. Solve by adding per + connection instance ID to pipe names. From Jussi Kivilinna. + - TCP: Fix an important TCP networking bug: 16-bit flags was being + converted to 8-bits in a few locations, causing loss of status + indications. + - TCP: net_startmonitor() always returned OK. In the race case + where a socket has already been closed, it correctly handled the + disconnection event but still returned OK. Returning OK caused the + callers of net_startmonitor() to assume that the connection was + okay, undoing the good things that net_startmonitor() did and + causing the socket to be incorrectly marked as connected. This + behavior was noted by Pelle Windestam. + - setsockopt() failed when setting timeouts to values less tha 100 + msec. That is because the timeout is limited to stops of 1 + decisecond and because the conversion of structure timeval was + truncating the microsecond remainder. The utility + net_timeval2dsec() now accepts and option to determine how it + handles the remainder: truncate, discarding the remainder, use + the remainder to round to the closed decisecond value, or use any + non-zero remainder to the next larger whole decisecond value. Bug + discovered by Librae. + - TCP: In the TCP connection operation, it was trying to setup the + network monitor BEFORE the socket was successfully connected. This, + of course, has ALWAYS failed because the socket is not yet connected + and the TCP state is not yet correct for a connected socket. However, + because of other changes net_startmonitor() now returns a failure + condition that causes worse problems when trying to connect. The fix + is to move the logic that starts the network monitor to AFTER the + socket has been successfully connected. + + * Atmel SAM3/4 Drivers: + + - SAM4CM and SAMA5D Free-running timer: Logic that samples the free + running counter reads the pending interrupt status register and can + cause interrupts to be lost. So, if when the status register is + read, the logic must also handle the timer overflow event. Found + and fixed by Max Neklyudov. + + * Atmel SAMA5 Drivers: + + - SAM3/4 Serial: When reconfigured, serial does not receive bytes + from UART. This happens because RX interrupt was disabled in the + setup routine. Fixed this I save interrupt configuration before + UART shutdown and restore it after. From Max Neklyudov. + + * NXP LPC17xx Drivers: + + - LPC176x GPIO: Reorder steps when an output GPIO is configured in + order to avoid transient bad values from being output. From Hal + Glenn. + - LPC17 USB OHCI: Correct some initialization of data structures. + When hub support is enabled, it would overwrite the end of an array + and clobber some OS data structures. + - LPC17xx Ethernet: Review, update, and modify the Ethernet driver so + that it works better with CONFIG_NET_NOINTS=y. Also, update all + LPC17xx networking configurations so that they have + CONFIG_NET_NOTINTS=y selected. + + * SiLabs EMF32 Drivers: + + - EFM32 SPI: Add missing SPI GPIO pin initialization. From Pierre-noel + Bouteville. + + * STMicro STM32: + + - STM32 F3: Added missing EXTI definitions for the STM32 F3; Correct + an error the port D base address in the STM32 F30x and F37x memory + maps. From Greg Meiste. + + * STMicro STM32 Drivers: + + - STM23 RTC: Fix an error introduced into stm32_pwr_enablebkp(). + That function must preserve the previous state of backup domain + access on return. + - STM32 RTC counter: Now need to enable backup domain write access + when setting the time. From Darcy Gong. + - STM32 OTG FS and HS: Added protection in the event that out-of-bound + endpoint numbers are received. From David Sidrane. + + * STMicro STM32 Boards: + + - STM32F429i Disco: (1) Fix a bad return value if the LCD driver is + already initialized. (2) The LCD driver initialization is now + performed during the early boot sequence. (3) Increased the size + of the message queue from 32 to 64 in the lcd configuration. From + Marco Krahl. + + * TI Tiva + + - Fixes for Tiva TM4C1294NCPDT. From Frank Sautter. + + * Atmel SAMV71 Drivers: + + - SAMV7 TWIHS: Fix SAMV TWIHS logic that performs multi-message + transfers with and without repeated starts. + + * Atmel SAMA5D3/4 Dirvers: + + - SAMA5 CAN: Fix SAMA5 CAN frame construction. From Max Holtzberg. + + * C Library/Header Files: + + - stdlib.h: MAX_RAND should be RAND_MAX. + - assert.h: Wrap definitions of assertion macros in do while so that + they are valid C statements. Numerous places throughout the code + where semicolons were missing at the end of an assertion also had to + be fixed. Suggested by orbitalfox. + - inetntoa(): Correct errors in printing IP address when type char is + signed and the value is >= 128. From Max Neklyudov. + + * Tools: + + - Tools: Fix test for the existence of the apps/ directory in + configure.c. Fix backward interpretation of options, -l was selecting + Windows and -w was selecting Linux. This was SourceForege Ticket #39. + + * Applications: apps/nshlib: + + - apps/nshlib/nsh_timcmds.c: Check return values from time functions. + - apps/nshlib/: Fix handling of gmtime_r return value in time commands. + gmtime_r returns a pointer, not an int. + + * Applications: apps/netutils: + + - apps/netutils/ntp: Fix mismatched sched_lock/unlock. Noted by Juha + Niskanen. + + * Applications: apps/examples: + + - apps/examples/nxlines: Fix missing right bracket that causes + compile error when CONFIG_NX_XYINPUT=y. From Librae. + - apps/examples: When boardctl() fails, need to print errno not the + returned value which will always be -1. + - apps/examples: Correct use of the BOARDIOC_GRAPHICS_SETUP boardctl() + call. diff --git a/configs/teensy-lc/README.txt b/configs/teensy-lc/README.txt index c40610e3eb..94c8890a50 100644 --- a/configs/teensy-lc/README.txt +++ b/configs/teensy-lc/README.txt @@ -1,9 +1,9 @@ Teensy LC README ================ - This is the README file for NuttX on the Teensy LC.
