This is actually an illegal use of strcpy() because one is not allowed to
use this function with overlapping source and destination buffers; whereas
memmove() is explicitly designed to handle such cases.
The compiler warning was:
../../../cpukit/libmisc/monitor/mon-editor.c:342:15: warning:
'strcpy' accessing 1 byte at offsets [0, 75] and [0, 75] overlaps
1 byte at offset [0, 74] [-Wrestrict]
|
|
The qsort() in sparse_disk_get_new_block() may move the appended key
which invalidates the pointer.
Close #4142.

The manager documentation is a consolidation of the comments in Doxygen
markup and the documentation sources in Sphinx markup. The
documentation was transfered to interface specification items. This
header file was generated from the items by a script.

This fixes the compiler warning below.
../../../cpukit/mghttpd/mongoose.c:1919:45: warning:
'.gz' directive output may be truncated writing 3 bytes into a region
of size between 1 and 255 [-Wformat-truncation=]
|

This patch does not only fix the compiler warning below. memcpy() is the
better function at this place as the terminating NUL character is never
copied here. Instead more characters will be appended to the
'logical_disk_name' later on.
../../../cpukit/libblock/src/bdpart-register.c:41:5:
warning: 'strncpy' output truncated before terminating nul copying
as many bytes from a string as its length [-Wstringop-truncation]

rtems_name is a four byte integer.
Giving an rtems_name as value instead of a pointer to ctrace_task_name_add()
fixes not only the compiler warning but it is also a bit more safe
For those who have asked for the warning:
../../../cpukit/libmisc/capture/capture_support.c:352:49: warning:
taking address of packed member of 'struct rtems_capture_task_record'
may result in an unaligned pointer value [-Waddress-of-packed-member]

Provide RTEMS_NO_RETURN also in case RTEMS_DEBUG is defined to prevent errors
like this:
error: no return statement in function returning non-void [-Werror=return-type]
Use C11 and C++11 standard means to declare a no-return function.

Before this patch RTEMS_Malloc_Initialize() had a fixed dependency on
_Workspace_Area. Introduce _Workspace_Malloc_initializer to have this
dependency only if CONFIGURE_UNIFIED_WORK_AREAS is defined by the
application configuration.

This patch fixes a tiny bug in the command line editing of the RTEMS shell.
Typing CTRL-U in the shell should remove all characters left of the cursor.
After pressing CTRL-U, the current implementation does wrongly place the cursor
at the end of the line instead at its beginning.
To reproduce the bug, start the shell and type 'abc123' (no <RETURN>):

> SHLL [/] # abc123
Then move the cursor onto the '1' by hitting three times the <ARROW-LEFT> key.
Next type <CTRL>-U:
> SHLL [/] # 123
Note that the cursor is at the end of the line (after '3') instead of correctly
at the beginning (on the '1'), now.
Continuing typing 'echo ' incorrectly results in the output:
> SHLL [/] # 123echo 123
The patch changes this behavior so that the cursor in the second last step will
be on the '1' and typing 'echo ' will then correctly reflected as:
> SHLL [/] # echo 123
Close #4097.

In contrast to message queues created by rtems_message_queue_create(), the
message queues constructed by this directive use a user-provided message buffer
storage area.
Add RTEMS_MESSAGE_QUEUE_BUFFER() to define a message buffer type for message
buffer storage areas.
Update #4007.
|
|
Add Message_queue_Control::is_global if RTEMS_MULTIPROCESSING is defined. This
reduces the Message_queue_Control size in standard RTEMS configurations.
Update #4007.
|
|
Move the CORE_message_queue_Buffer definition to a separate header file to be
able to use it independent of the remaining Message Queue Handler API.
Change license to BSD-2-Clause according to file history.
Update #3053.
Update #4007.
|
|
Merge CORE_message_queue_Buffer structure into
CORE_message_queue_Buffer_control.
Use a zero-length array for the actual message buffer. This reduces the
structure size on all targets.
Update #4007.

Return a status code and differentiate between error conditions.
Update #4007.
|
|
Initialize the structure in a single code block after the error checks and
calculations.
Update #4007.

The previous multiplication error check is broken on 64-bit machines. Use the
recommended check from SEI CERT C Coding Standard, "INT30-C. Ensure that
unsigned integer operations do not wrap".
Make sure the message size computation does not overflow.

In contrast to rtems_task_create() this function constructs a task with
a user-provided task storage area. The new directive uses a
configuration structure instead of individual parameters.
Add RTEMS_TASK_STORAGE_SIZE() to calculate the recommended size of a
task storage area based on the task attributes and the size dedicated to
the task stack and thread-local storage. This macro may allow future
extensions without breaking the API.
Add application configuration option
CONFIGURE_MINIMUM_TASKS_WITH_USER_PROVIDED_STORAGE to adjust RTEMS
Workspace size estimate.
Update #3959.
|
|
Add this application configuration option. This configuration option can be
used to reserve space for the dynamic linking of modules with thread-local
storage objects.
Add RTEMS_TASK_STORAGE_ALIGNMENT to define the minium alignment of a
thread-local storage size.
