3e6c196ffa arch/ and config/ files: All board interfaces (those starting with board_) must be defined in board-specific logic. Otherwise, they cannot be customized of specialized usage by different boards. The board_reset() interface was defined in architecture-specific logic that only called up_systemreset(). That is useless!
This change removes the board_reset() implementation from the architecture-specific code and re-implements in the src/ directory of each board that has CONFIG_BOARDCTL_RESET enabled.  That is the correct functional partitioning.

a77c073797 arch/: Fix an interlock that was broken by commit 641a98a434 in all implementations of up_sigdeliver. 2019-02-03 17:14:32 -06:00
Gregory Nutt
641a98a434 arch/: The saved return register state is available on the user stack. Thic commit reorders some logic so that certain, critical registers are preserved in the TCB. This does not make the logic 100% secure, but does prevent some obvious things. sched/signal/sig_delivery: Add a flag to the TCB to indicate that we are in a signal handler. Use this flag to assure that a there a never attempts to nest signal handling operations on a thread. This was guaranteed before but when locking of pre-emption during signal delivering was eliminated in a previous commit, there was a remote possibility of an attempt to do nested signal handling. This flag assures that there is only one signal handled at a time. 2019-02-03 15:29:47 -06:00

763ba51b78 arch/xxx/src/xxx/up_assert.c: Dump CPU0 IDLE stack only when PID equals 0. IDLE threads of other CPUs do not need this special check 2019-01-26 10:59:23 -06:00

db24306435 arch/assertion logic: Fix additional places where the test for an IDLE task is incorrect. It is not invalid in all configurations to check for PID==0. However, the logic fixed in these places lackes sufficient intelligence to find the right stack for the CPU IDLE thread and could still show the wrong stack. 2018-12-18 17:45:46 -06:00

ec9265aa95 arch assertions: Correct duplicated logic from commit dbf01d12b7. Checking for PID == zero is not a valid way to test for the IDLE task in all configurations! This is only true in the single CPU configuration. In multiple CPU configurations, there will be a separate IDLE task for each CPU with a different PID. 2018-12-18 17:35:42 -06:00

dbf01d12b7 Assertions: Identify the running task correctly when dumping task state information. It takes time to switch to the target task after g_readytorun has been modified. If panic/assert happen during this period, the dump will contain the incorrect and confusing information due to the difference between the real running task and the return value of this_task(). This change resolve this problem by adding g_running_task to track the real running task through the context switch. 2018-11-15 07:11:51 -06:00

a94e3284b3 syslog: Enable is partial, crippled version of syslog_flush(); arch/: Call syslog_flush() from assertion handling logic. 2018-06-07 16:29:16 -06:00
Gregory Nutt
977d41d519 Based on a change recommended by Mark Shulte:
Signal handlers maybe run with interrupts enabled or disabled, depending on how the task the received the signal was blocked. (i.e.: If sem_wait() is called, then we disable interrupts, then block the currently running task). This could be dangerous, because user code would be running with interrupts disabled.

This change forces interrupts to be enabled in up_sigdeliver() before executing the signal handler calling up_irq_enable() explicitly.  This is safe because, when we return to normal execution, interrupts will be restored to their previous state when the signal handler returns.
