Compilers allocate some section of memory without using wrapper function,
which is later freed when wrappers were initialized. Since the allocated
memory didn;t contain wrapper header the pointer got corrupt when calling to free.
This implementation of signature addition during malloc and signature check during
free helps in freeing the memory allocated by wrapper functions properly and
also the internal memory allocated by compilers (without malloc wrappers).
malloc guarantees aligned memory. If we add an alignment here, we are adding
additonal unused 4 bytes. Each allocator has its own 4/8 byte header
(GGC / ARM have 4 bytes).
So if user request for 8 bytes of memory stats will add 8 + allocator 8.
However if we remove the alignment in stats header, allocator will consider
add 4 bytes to 12 byte request and zero padding.
It will be beneficial to leave the padding to allocator.
New classes covered with unit tests: SocketAddress, EthernetInterface, EMACInterface, WiFiAccessPoint.
Also added missing namespace in front of mbed::Callback usages.
EMACInterface is covered by the EthernetInterface unit tests.
When socket created using accept() is closed by calling the close()
method, "delete this" is executed which triggers the destructor call
on TCPSocket which in turn calls close() once again. Because _stack
is already 0 this results in a hard-fault.
Add a check that skips the rest of the close() method is the _stack
is already 0.
You are allowed in POSIX / ANSI C to read and write on the same stream, but you
have to do an fseek in between read and write call (getc->fseek->putc)
Thanks @Alex-EEE for sharing the fix: https://github.com/ARMmbed/mbed-os/pull/7749
Added test case for verification of the behavior
### Description
The error message when you invoke `mbed dm update prepare` without a payload
is particularly obtuse, and provides a user with no indication that the
payload is missing. This change makes that error message not stink.
### Pull request type
[x] Fix
[ ] Refactor
[ ] Target update
[ ] Functionality change
[ ] Breaking change
Set the ISR stack to be 1KB. https://github.com/ARMmbed/mbed-os/pull/7238
Set the heap size to 3KB(2KB + overhead + spare) so that atleast 2KB free ram is
available for testing.
With dynamic heap size, explicit size is not required. IAR 7.8 supports
static heap, hence the change is needed in IAR linker files.
