* score: Fix watchdog insertSebastian Huber2016-01-051-4/+12
| | | | | | | | | Under certain conditions a new watchdog was inserted with a wrong and very large delta interval due to a wrong iterator update. Bug was introduced by 1ccbd052910ed16131c74b0d5595c8a94066942d. Close #2507.
* score: Fix watchdog removalSebastian Huber2015-12-211-1/+10
| | | | | | | | | Under certain conditions a new watchdog was inserted with a wrong and very large delta interval due to an incomplete iterator update. Bug was introduced by 1ccbd052910ed16131c74b0d5595c8a94066942d. Close #2501.

* untar: do not exit with error when created directory already exists.Pavel Pisa2015-11-232-2/+46
| | | | | | | | | | | | | | The problem exists for both RTEMS untar implementations and their variants: Untar_FromMemory(), Untar_FromFile() and rtems_tarfs_load(). If filesystem object already exists at extracted directory path then if it is directory, creation is ignored. Attempt to delete/unlink object and make directory is tried for other cases. This simple approach problem reported in ticket fixes #2413. Behavior follows GNU tar and BSD tar practice for directories but much more work is required to achieve full semantics of the full featured tar implementation still.
* sparc: Fix context switch on SMPDaniel Cederman2015-11-171-0/+3
| | | | | | | | | | | | | | | | | | We must not load registers (e.g. PSR) from the heir context area before the heir stopped execution. With this patch the write to PSR is divided into two steps. We first update the current window pointer and then we restore the status registers and enable traps. This allows us to move the first write to PSR to be before the write to WIM, as there is now no risk that we get an interrupt where the CWP and WIM would be inconsistent. We only need to make sure that we do not use any of the non-global registers or instructions that affects CWP for three instructions after the write. In the earlier code the non-global %o1 register was used right after the write to PSR, which required the use of three nop:s. Close #2472.
* score: Fix race condition on SMPSebastian Huber2015-11-173-41/+67
| | | | | | | | We must ensure that the Thread_Control::Wait information update is visible to the target thread before we update its wait flags, otherwise we may return out of date events or a wrong status. Close #2471.
* Fix interrupt epilogue for ARMv7-AR and PowerPCSebastian Huber2015-11-171-0/+27

* ada: Add missing includeJan Sommer2015-10-301-0/+1
| | | | | Include stackimpl.h otherwise PTHREAD_MINIMUM_STACK_SIZE cannot be evaluated.

* rbheap: Fix rtems_rbheap_free()Sebastian Huber2015-09-111-23/+15
| | | | | | | Remove unused descriptor of merged free chunks from the free chain and add them to the spare descriptors. Update #2417.
* cpukit/libmisc/dumpbuf/dumpbuf.c: Fix compilation warningsMartin Galvan2015-09-031-1/+1
| | | | | | | | | | Compiling dumpbuf.c causes the following warning to be issued: warning: pointer targets in passing argument 1 of 'snprintf' differ in signedness [-Wpointer-sign] This happens because line_buffer is declared as unsigned. Closes #2411.
* cpukit/libnetworking/rtems/rtems_dhcp.c: Fix compilation errorMartin Galvan2015-09-031-1/+1
| | | | | | | | Apparently 'free' is defined as a macro which takes two arguments and calls rtems_bsdnet_free. When fixing #2405 I added a missing 'free' but didn't notice it was non-standard. Closes #2410.
* cpukit/libmisc/dumpbuf/dumpbuf.c: Fix undefined behavior for sprintf()Martin Galvan2015-09-031-46/+75
| | | | | | | I also used the 'n' versions of the string functions, #define'd magic numbers and added a few comments. Updates #2405.
* cpukit/libnetworking/rtems/rtems_dhcp.c: Fix leak on realloc failure for ↵Martin Galvan2015-09-031-5/+13
| | | | | | dhcp_hostname. Closes #2405.

* powerpc: Do not use the ATB for e500 multilibSebastian Huber2015-07-151-1/+1
| | | | | | The e500v1 has no support for the ATB. Update #2369.
* powerpc: Fix _CPU_Counter_read()Nick Withers2015-07-151-1/+1
| | | | | | The mftb is not available on Book E processors. Use SPR 268 instead. Close #2369.
* libcsupport: Workaround for GCC 5.1 and laterSebastian Huber2015-07-152-2/+7
| | | | | Disable an optimization which would lead to a recursive calloc() call in calloc().
* libnetworking: Send the hostname if set in the network configuration.Chris Johns2015-07-141-2/+16
| | | | | This allows a suitably configured DHCP server with DDNS to enter the name into the DNS table making it addressiable via it's host name.
* score: Simplify _Thread_Lock_set()Sebastian Huber2015-07-131-11/+56
| | | | | Exploit the fact that the current thread lock must be the default thread lock and interrupts are disabled if we call _Thread_Lock_set().

* score: Simplify _SMP_ticket_lock_Release()Sebastian Huber2015-07-012-12/+13
| | | | | Add a SMP lock statistics pointer to SMP_lock_Stats_context and drop the SMP lock statistics parameter from _SMP_ticket_lock_Release().
* score: Accept NULL pointer in _Freechain_Put()Sebastian Huber2015-07-012-2/+5
| | | | With this a _Freechain_Put( _Freechain_Get() ) works always.
* score: Freechain handler API changesSebastian Huber2015-07-014-81/+85
| | | | | Replace the extend function with an allocator since this fits better to the current use case.
* score: Hide SMP lock profiling impl if disabledSebastian Huber2015-06-264-82/+131
| | | | The problem is that empty structures have a different size in C and C++.
* libmisc: Simplify <rtems/stackchk.h>Sebastian Huber2015-06-262-1/+2
| | | | | Drop the <rtems/score/percpu.h> include since this file exposes a lot of implementation details.

| | | | | Drop the <rtems/score/percpu.h> include since this file exposes a lot of implementation details.

* score: Simplify <rtems/score/thread.h>Sebastian Huber2015-06-255-44/+44
| | | | | | Avoid Thread_Control typedef in <rtems/score/percpu.h>. This helps to get rid of the <rtems/score/percpu.h> include in <rtems/score/thread.h> which exposes a lot of implementation details.

* rtems: Add rtems_interrupt_local_disable|enable()Sebastian Huber2015-06-222-2/+45
| | | | | | | | Add rtems_interrupt_local_disable|enable() as suggested by Pavel Pisa to emphasize that interrupts are only disabled on the current processor. Do not define the rtems_interrupt_disable|enable|flash() macros and functions on SMP configurations since they don't ensure system wide mutual exclusion.
