The new core-internal 'Address_space' interface enables cores RM service
to flush mappings of a PD in which a given 'Rm_client' thread resides.
Prior this patch, each platform invented their own way to flush mappings
in the respective 'rm_session_support.cc' implementation. However, those
implementations used to deal poorly with some corner cases. In
particular, if a PD session was destroyed prior a RM session, the RM
session would try to use no longer existing PD session. The new
'Address_space' uses the just added weak-pointer mechanism to deal with
this issue.
Furthermore, the generic 'Rm_session_component::detach' function has
been improved to avoid duplicated unmap operations for platforms that
implement the 'Address_space' interface. Therefore, it is related to
issue #595. Right now, this is OKL4 only, but other platforms will follow.
This enables us to use the run scripts applied to a native machine equipped
with Intel's AMT. If the environment variables are correctly set up, the remote
test machine is reseted via 'amttool', then via 'amtterm' the serial output
is collected and the normal run script matching pattern for success/failure of
the run script are applied.
'amttool' and 'amtterm' are part of the package called 'amtterm' shipped with
the Linux distributions like Ubuntu, Debian and lot more.
Following environment variables are required, to run the run scripts with a
native AMT test machine:
PXE_TFTP_DIR_BASE - absolute path of TFTP directory
PXE_TFTP_DIR_OFFSET - relative path to PXE_TFTP_DIR_BASE where the config file
will be generated - named 'config-00-00-00-00-00-00'
AMT_TEST_MACHINE_IP - TCP/IP address of target AMT test machine
AMT_TEST_MACHINE_PWD - password of target AMT test machine
Issue #679
Since checking if the certificate is valid is not that important
(we currently do not check the signature of the archive which is the
bigger issue) we disable the checking to prevent certain wget version
from refusing to download the archive.

mkisofs is the original ISO creation tool from cdrtools available on
many UNIX systems. genisoimage on the other hand is part of a mostly
unmaintained fork of cdrtools very specific to Debian Linux and its
derivates (e.g., Ubuntu). Fortunately, genisoimage (as we used it) is
completely invocation-compatible to mkisofs.
Fixes#627.
Instead of trying all PCI devices by a specific PCI driver, now the device or
the device class can be limited to the one actually supported by the specific
driver.
The "strncpy - not implemented" message appeared on the use of libpng.
Even though it did not cause trouble, spilling the log with such
easy-to-fix issues should better be avoided.
Bender fixes the serial output on modern PC hardware. Prior this patch,
it was used only when combined with pulsar. Now, we also use it when
booting via GRUB.
Allocate ever an extra page behind the commandline pointer. If it turns out
that this page is unused, because commandline was short enough, unmap the
memory and put the virtual and physical regions back to the allocator.
Fix#664
With this patch, the 'futex' syscall gets used for blocking and unblocking
of threads in the Linux-specific lock implementation.
The 'Native_thread_id' type, which was previously used in the
lock-internal 'Applicant' class to identify a thread to be woken up,
was not suitable anymore for implementing this change. With this patch,
the 'Thread_base*' type gets used instead, which also has the positive
effect of making the public 'cancelable_lock.h' header file
platform-independent.
Fixes#646.
Revoke the right to set the portal id (aka label) when it is not needed
anymore. Otherwise everybody in the system having a mapping of the portal can
reset the label to something we don't expect.
Issue #667
In base-fiasco, base-foc and base-pistachio, physical memory gets mapped
1:1 to core virtual memory. When the 'Ram_session_component' allocates
physical memory for a client, it zeroes out the corresponding area in
core's virtual address space and then maps the area to the client. If this
area overlaps with core's virtual thread context area (usually at
0x40000000-0x4fffffff), the stack of one or more core threads can get
overwritten.
To avoid this problem, with this patch, the thread context area gets
removed from the physical RAM allocator on these platforms.
Fixes#660.
Without the patch the signal cap was ever transferred to the timer session
when a usleep/msleep was called, even when unneeded. On base-nova this
causes the allocation of new capability indexes which are not freed up.
So the timer service run quickly out of indexes and get out of order...
