Unless '-ignorestderr' is set on 'exec' in expect, any output on stderr
is interpreted as execution failure. In this case, 'create_iso' logs
some diagnostics but does not fail.
We repeatedly promote our ISOs to be bootable from USB storage.
Therefore, we have a hard dependency on 'isohybrid' and should fail in
the case that the tool is missing.
Access to a block session is provided by using the block file system.
By specifying the label, each block session request can be routed to
the proper block session provider:
! <fstab>
! ...
! <dir name="dev">
! <block name="blkdev0" label="block_session_0" />
! </dir>
! ...
! </fstab>
In addition to this file system, support for the DIOCGMEDIASIZE ioctl
request was added. This request is used by FreeBSD and therefore our
libc to query the size of the block device in bytes.
Fixes#1010.
All source codes of the glue code between Vancouver and Genode that were
based on existing GPL code had already stated that Genode Labs is not
the sole owner of the code. To make the distinction between the Genode
OS framework and the glue code more clear, this patch removes the text
"is part of the Genode OS framework" from the glue code.
Instead of, passing responsibility to manage and dissolve Signal_rpc_member
objects at a corresponding entrypoint to the user, hand over entrypoint's
reference to the constructor, and do it in the constructor resp. destructor
of the class.
Fixes#1022
Both base/src/test/thread and base-okl4/src/test/okl4_03_thread used the
same target name, which ultimately confused the build system when
building on OKL4.
File systems using the File_system_session interface can now be
synchronized by using this syscall. This is needed for file system
that maintain an internal cache, which should be flushed.
Fixes#1008.
Users of a File_system_session might want to force a file system
to flush or rather to synchronize its internal cache. A concret
default implementation is provided because not all file systems
maintain an internal cache and are not required to synchronize
caches.
Fixes#1007.
Fail hard if no large enough virtual memory area can be found where to map
the memory from the kernel to core.
Additionally clear dataspaces in junks if it can't be done in one large junk.
Fixes#1011
Make 'set_program_var' accessible outside of 'rtld.c'. Also, compile
dynamically linked programs with the '-fPIC' option. Doing not so,
yields to program-global symbols being put in the '.symtab' section
(which can be stripped) only. In order to get access to global
variables from the dynamic linker, the symbols need to reside within
the '.dynsym' section additionally. Hence the '-fPIC'.
ref #989fix#1002
If an RM client gets dissolved the RM server tries to first
dissolve and then destruct the according pager object. As pager objects
previously cancelled unresolved faults only in destructor the dissolve
operation blocked forever when an unresolved fault existed.
As every pager object should get dissolved before it gets destructed
(signal-context complains otherwise) no more unresolved-fault cancelling
is needed in the destructor.
ref #989
As synchronization of signal contexts is now the users business instead of
cores and the signal framework ensures that every context of a receiver gets
synchronously destructed before the destruction of the receiver itself
synchronization and thus blocking at the destruction of a kernel
receiver-object isn't necessary anymore.
ref #989
Kernel::signal_context_kill can be used by any program to halt the processing
of a signal context synchronously to prevent broken refs when core destructs
the according kernel object. In turn, Kernel::bin_signal_context doesn't block
anymore and destructs a signal context no matter if there are unacknowledged
signals. This way, cores entrypoint doesn't depend on signal acks of a
untrustworthy client anymore.
ref #989
In the future bin_* means the direct destruction of a kernel object
without any blocking. kill_* in contrast is used for bringing a
kernel object such as signal contexts synchronized into a sleeping
state from where they can be destructed without the risk of getting
broken refs in userland.
ref #989
To remap its UTCB to its context area later, a main thread needs
to know the according dataspace capability. This is done through
the start-info it receives from its creator at startup.
ref #989
I have no idea where the previous default alignment = 2 in the unsynchronized
singleton came from but as at least the Arndale IC-driver in base-hw needs an
alignment of 4 = address width, unmanaged singleton now uses sizeof(addr_t)
as default alignment.
