69318b1024 Re-implements reverted commit 344f7bc9f61d139b932bf6c6a5001e7a8e54409d in a way that should not have the undesired side-effect. include/nuttx/sched.h: Add a bit to the TCB flags to indicat the thread is a user thread in a syscall. sched/nuttx/nxsig_dispatch.c: Delay dispatching to signal handlers if within a system call. In all syscall implementations: Process delayed signal handling when exiting system call. 2019-11-28 12:47:36 -06:00

cbdd590c82 Revert "include/nuttx/sched.h: Add storage for a previous signal mask. arch/: In all syscall implementations, block all signals before dispatching a system call; resotre signal mask when the system call returns." 
Using the sigprocmask() for this purpose has too many side-effects.

This reverts commit 344f7bc9f61d139b932bf6c6a5001e7a8e54409d.

bb623d1e04 This commit renames all internal OS functions defined under sched/task so that they begin with the prefix. For example, nxtask_exit() vs. task_exit().

    Trivial, cosmetic
    sched/, arch/, and include:  Rename task_vforkstart() as nxtask_vforkstart()
    sched/, arch/, and include:  Rename task_vforkabort() as nxtask_vforkabort()
    sched/, arch/, and include:  Rename task_vforksetup() as nxtask_vfork_setup()
    sched/:  Rename notify_cancellation() as nxnotify_cancellation()
    sched/:  Rename task_recover() to nxtask_recover()
    sched/task, sched/pthread/, Documentation/:  Rename task_argsetup() and task_terminate() to nxtask_argsetup() and nxtask_terminate(), respectively.
    sched/task:  Rename task_schedsetup() to nxtask_schedsetup()
    sched/ (plus some binfmt/, include/, and arch/):  Rename task_start() and task_starthook() to nxtask_start() and nxtask_starthook().

a77c073797 arch/: Fix an interlock that was broken by commit 641a98a434b5819eba15b6ad494f0e3a8fa33978 in all implementations of up_sigdeliver. 2019-02-03 17:14:32 -06:00

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
Gregory Nutt
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 dbf01d12b7321d1b48b68d3b69842a853b049376. 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

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.

de6b13b3ab Per OpenGroup.org, syslog -- and, hence, nonstandard vsyslog, and debug wrappers -- does not return a value. Rename _vsyslog to nx_vsyslog. Use internal nx_vsyslog in the few cases where a return value is required. 2018-03-04 08:07:07 -06:00

passed back when the isr is called.

For Cygwin, that support depends on the 'cygpath -w' tool to convert POSIX paths to Windows paths. There is no corresponding tool for Ubuntu under Windows 10. 2017-01-01 16:29:03 -06:00
