Within the central security unit of the i.MX53 SoC, one can set protection
level of various DMA bus master requests, distinguishing them between normal,
and secure access. Although, the access level was meant to be set correctly,
the enumeration values that denoted the kind of access were incorrect. Thereby,
until now every DMA requests was set as being secure. This commit corrects
the enumeration values, and sets all DMA operations as being unsecure, accept
from the graphical subsystem which is controlled by the secure world only.
Thanks to Andrea Barisani and Andrej Rosano from Inverse Path for discovering
this bug, as well as the hardware limitation!
The timed semaphore supports a minimum timeout of 10 ms and logs a
warning if the timeout is lower than the minimum. To prevent the
warning, we limit timeouts to >= 10 ms.
Adding this function eases the implementation of realloc based on
'Libc::Mem_alloc'. Note that this allocator is not used by libc's
default malloc implementation but it is useful for customized C
runtimes, e.g., for the runtime of VirtualBox.
This function provides a way to request the size of an previously
allocated block. It is useful to to ease the implementation of realloc
functionality based on Allocator_avl.
This information is useful if 'libc-common.inc' is included from
another repository, i.e., for building stripped-down libc variants
tailored to an individual application.
Out of laziness we only provide two dummy functions for all FUSE
operations, which are used in case the FUSE file system does not
implement them itself.
Fixes#1058.
Omit the main rountine in fuse-ext2.c. Otherwise using fuse-ext2 with
fuse_fs is not possible because the server framework already defines
a main routine.
Fixes#1058.
* add sync method:
Since file systems tend to have a inbuild caching mechansim we need to
sync these caches at the end of session when using the fuse_fs server.
Therefore each FUSE file system port has to implement a Fuse::sync_fs()
function that executes the necessary actions if requested.
* add symlink check
* allow to check FUSE fs initialization
This changes the private API of the FUSE implementation. The init_fs
method now has to return true if the initialization was successful and
otherwise false. All current users of the API are also changed
accordingly.
Fixes#1058.
Noux generates 'argv[0]' for the initial child automatically (in contrast
to the 'config_args' library), so the first argument stated in the
configuration should not be the GDB program name.
Fixes#1062.
On Genode/Fiasco.OC, when an unresolved page fault occurs, only the IP and
SP registers are valid in the thread state read by GDB monitor. This was
not taken into account so far and the other (possibly outdated) register
values got reported to the client, too.
With this patch, only IP and SP get reported to the client in the page
fault case.
Fixes#1063.
For further information see: http://wiki.netbsd.org/rumpkernel/. In this version
I ported the central rump components to Genode in order to take advantage of
NetBSD file system implementation. The new 'dde_rump' repository contains the
Genode version of the rump libraries and a 'rump_fs' server that implements
Genode file-system-session interface. Currently ext2, iso9660, and fat
file-systems are supported.
Issue #1048
'check_installed' takes a command name as argument and tries to call 'which' in
order to find the command path. If that does not succeed, paths like '/sbin' are
'/usr/sbin' searched. On success the absolute path of the command is returned,
on failure 'exit' is called with an error message.
