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not taken into account so far and the other (possibly outdated) register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.
Issue #1048
Previously we used to many registers in syscalls with much arguments
to build with optimization level O0. Additionally this fix fastens the
userland backend of syscalls.
All the pre- and post-processing of the startup lib around the main
function of a dynamic program is now done by LDSO. Hence LDSO directly
calls the main function of the program.
Issue #1042
This is needed later when eliminating the need for a startup lib in
dynamic programs to enable LDSO to call ctors and dtors of the program.
Issue #1042
After some research we found that the stack pointer on ARM platforms must be
at least double word aligned (See: "Procedure Call Standard for the ARM
Architecture" - 5.2.1.1). Since a 'call' on ARM will not result in a stack pointer
change (like on x86), the current behavior resulted in a 4 Byte aligned stack
only.

This commit generalizes the bit array in 'base/util/bit_array.h',
so that it can be used in a statically, when the array size is known
at compile time, or dynamically. It uses the dynamic approach of the
bit array for a more generalized version of the packet allocator,
formerly only used by NIC session clients. The more generic packet
allocator is used by the block cache to circumvent the allocation
deadlock described in issue #1059.
Fixes#1059
Base libraries are already contained within ldso.lib.so. Remove unnecessary
filtering from 'dep_lib.mk', make ldso depend on base libs.
