The downloaded archives for building the tool chain are checked for its
signature before using them. In case of a signature failure, the build
is interrupted.
Issue #748
The signature verification tool uses gpg to verify the detached
signature of the given file.
It also tries to obtain the signing key if it is not part of the local
key ring.
Signature verification implies the verification of the integrity and
authenticity of a given file.
Issue #748
Instead of using a fixed command like picocom in the run tool,
it's better to have the flexibility to set the whole command that
connects to the serial device. Therefore, it's possible for instance
to connect to a remote serial device exported via TCP/IP by using tools
like socat.
This patch introduces a new platform 'linux_arm' for building and running
Genode/Linux on an ARM device.
Known limitations:
- libc 'setjmp()'/'longjmp()' doesn't currently save/restore floating
point registers
Fixes#746.
If the target machine is connected locally one may specify
"serial" as target in the RUN_OPT variable to get the test output.
Used for panda and arndale on foc and hw.
Use RUN_OPT="--target ..." to select the backend test method.
Supported values so far:
qemu - qemu + grub bootloader (default)
qemu+pxe - qemu + pulsar bootloader (PXE)
amt - Intel AMT (reset+serial output) + pulsar bootloader

genode_until_run can be called now with a spawn id to able to reattach to a
spawned process (amt, serial output). Run scripts can now call genode_until_run
multiple times.
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.
This base platform is no longer maintained.
For supporting the Microblaze CPU in the future, we might consider
integrating support for this architecture into base-hw. Currently
though, there does not seem to be any demand for it.
The 'Timer::Session::msleep' function is one of the last occurrences of
long-blocking RPC calls. Synchronous blocking RPC interfaces turned out
to be constant source of trouble and code complexity. I.e., a timer
client that also wants to respond to non-timer events was forced to be a
multi-threaded process. This patch replaces the blocking 'msleep' call
by a mechanism for programming timeouts and receiving wakeup signals in
an asynchronous fashion. Thereby signals originating from the timer can
be handled along with signals from other signal sources by a single
thread.
The changed interface has been tested on Linux, L4/Fiasco, OKL4, NOVA,
L4ka::Pistachio, Codezero, Fiasco.OC, and hw_pbxa9. Furthermore, this
patch adds the timer test to autopilot.

This should ensure that the directory is created before trying to
create a file within it.
This hopefully fixes errors like the following when using parallel
builds:
checking library dependencies...
/bin/bash: line 19: var/libdeps: No such file or directory
make[5]: *** [init_libdep_file] Error 1
'Bender' can detect serial ports accessible via PCI and writes the I/O ports
to the Bios Data area (BDA).
Usage together with the PXE bootloader ease life running Genode/NOVA on native
hardware, where a standard serial device isn't available anymore anywhere.
There is no obvious reason for having two different SPEC variables, definitions,
and pathes for the Pandaboard platform. It even lead to problems regarding the
omap4 framebuffer driver (look at issue #505 and #506).
Using the new 'join()' function, the caller can explicitly block for the
completion of the thread's 'entry()' function. The test case for this
feature can be found at 'os/src/test/thread_join'. For hybrid
Linux/Genode programs, the 'Thread_base::join()' does not map directly
to 'pthread_join'. The latter function gets already called by the
destructor of 'Thread_base'. According to the documentation, subsequent
calls of 'pthread_join' for one thread may result in undefined behaviour.
So we use a 'Genode::Lock' on this platform, which is in line with the
other platforms.

The bash-builtin 'pwd' command uses the 'st_dev' and 'st_ino' members of
the 'stat' struct to compare the path from the 'PWD' environment variable
with the path returned by 'getcwd()'. These members don't get set
correctly in Noux and therefore the 'pwd' command sometimes returns wrong
results when building Genode in Noux. With this patch the 'CURDIR' make
variable gets used instead of calling 'pwd'.
Fixes#454.
The 'build.mk' file checks if the tool chain to be used supports the
'-static' and '-fno-stack-protector' flags, but this check always fails
for the current Genode tool chain because it cannot create executable
files without explicitly specifying the 'crt0' and library files to be
linked, which the check doesn't.
This patch removes the compiler check.
Fixes#358.
