itest: allow map_physmem to return 0 in limited cases
On some systems, RAM starts at address 0. If the user executes itest
against address 0 on such a system, it will call map_physmem(0, ...)
which will return 0 back; mapping only changes the address on sandbox.
This causes itest to believe map_physmem() has failed, and hence fails
the comparison.
Fix itest so that it allows map_physmem() to return 0 /if/ the orignal
address passed to it was also 0.
This fixes "tegra-uboot-flasher flash" on Tegra20.
This has the disadvantage that on sandbox, failed mapping attempts for
address 0 are not detected. Instead, should the code only call
map_physmem() on sandbox? Or, should map_physmem() return its error status
some other way. Or, should the special case only be allowed on systems
where the base of RAM is 0 somehow?

gunzip: remove avail_in recalculation
Current, the following passes:
./u-boot -d arch/sandbox/dts/test.dtb -c 'ut_image_decomp'
but the following fails:
./u-boot -d arch/sandbox/dts/test.dtb -c 'ut dm; ut_image_decomp'
This is because the gunzip code reads input data beyond the end of its
input buffer. In the first case above, this data just happens to be 0,
which just happens to trigger gzip to signal the error the decompression
unit test expects. In the second case above, the "ut dm" test has written
data to the accidentally-read memory, which causes the gzip code to take a
different path and so return a different value, which triggers the test
failure.
The cause of gunzip reading past its input buffer is the re-calculation of
s.avail_in in zunzip(), since it can underflow. Not only is the formula
non-sensical (it uses the delta between two output buffer pointers to
calculate available input buffer size), it also appears to be unnecessary,
since the gunzip code already maintains this value itself. This patch
removes this re-calculation to avoid the underflow and redundant work.
The loop exit condition is also adjusted so that if inflate() has consumed
the entire input buffer, without indicating returning Z_STREAM_END (i.e.
decompression complete without error), an error is raised. There is still
opportunity to simplify the code here by splitting up the loop exit
condition into separate tests. However, this patch makes the minimum
modifications required to solve the problem at hand, in order to keep the Acked-by: Kees Cook <keescook@chromium.org>
diff simple.
I am not entirely convinced that the loop in zunzip() is necessary at all.
It could only be useful if inflate() can return Z_BUF_ERROR (which
typically means that it needs more data in the input buffer, or more space
in the output buffer), even though Z_FINISH is set /and/ the full input is
available in the input buffer /and/ there is enough space to store the
decompressed output in the output buffer. The comment in zlib.h after the
prototype of inflate() implies this is never the case. However, I assume
there must have been some reason for introducing this loop in the first
place, as part of commit "Fix gunzip to work for any gziped uImage size".
This patch is similar to the earlier b75650d84d4b "gzip: correctly
bounds-check output buffer", which corrected a similar issue for
s.avail_out.

test/py: support running sandbox under gdbserver
Implement command--line option --gdbserver COMM, which does two things:
a) Run the sandbox process under gdbserver, using COMM as gdbserver's
communication channel.
b) Disables all timeouts, so that if U-Boot is halted under the debugger,
tests don't fail. If the user gives up in the middle of a debugging
session, they can simply CTRL-C the test script to abort it.
This allows easy debugging of test failures without having to manually
re-create the failure conditions. Usage is:
When using this option, it likely makes sense to use pytest's -k option
to limit the set of tests that are executed.
Simply running U-Boot directly under gdb (rather than gdbserver) was
also considered. However, this was rejected because:
a) gdb's output would then be processed by the test script, and likely
confuse it causing false failures.
b) pytest by default hides stdout from tests, which would prevent the
user from interacting with gdb.
While gdb can be told to redirect the debugee's stdio to a separate
PTY, this would appear to leave gdb's stdio directed at the test
scripts and the debugee's stdio directed elsewhere, which is the
opposite of the desired effect. Perhaps some complicated PTY muxing
and process hierarchy could invert this. However, the current scheme
is simple to implement and use, so it doesn't seem worth complicating
matters.
c) Using gdbserver allows arbitrary debuggers to be used, even those with
a GUI. If the test scripts invoked the debugger themselves, they'd have
to know how to execute arbitary applications. While the user could hide
this all in a wrapper script, this feels like extra complication.
An interesting future idea might be a --gdb-screen option, which could
spawn both U-Boot and gdb separately, and spawn the screen into a newly
created window under screen. Similar options could be envisaged for
creating a new xterm/... too.
--gdbserver currently only supports sandbox, and not real hardware.
That's primarily because the test hooks are responsible for all aspects of
hardware control, so there's nothing for the test scripts themselves can
do to enable gdbserver on real hardware. We might consider introducing a
separate --disable-timeouts option to support use of debuggers on real
hardware, and having --gdbserver imply that option.

malloc: solve dead code issue in memalign()

code to be dead code; the "retry" logic is always activated under the same
condition that the original failure detection code is, and also fully
handles any possible failures. This patch solves the presence of dead
code.
Two alternatives are possible:
a) Delete the now-dead test, and rely on the "retry" path to handle any
allocation problems, as it does.
b) Make the "retry" path fall through to the existing (currently dead)
failure detection code, thus making it not-dead.
(b) was chosen since it reduces the diff between U-Boot's and the upstream
dlmalloc. This should make it marginally easier to import a new version of
