Until now, there was not exception type for the condition where a
symlink was created on a file system w/o supporting symlinks, e.g., FAT.
The corresponding file-system server (ffat_fs) used to return a negative
handle as a work around. I added 'Permission_denied' to the list of
exceptions thrown by 'File_system::Session::symlink' to handle this case
in a clean way.
The test used to rely on a writable root directory. To reuse the test
for the new VFS, where '/' is never writable, I changed all absolute
paths to relative paths.
The 'tinfo.cc' file needs to get built, because it implements
'std::type_info::operator==(std::type_info const&) const', which
is needed by the 'icu' library on ARM.
Fixes#1109.
This patch removes the 'Framebuffer::Session::release()' function from
the interface to make the mode-change protocol consistent with the way
the Rom_session interface handles ROM-module changes. That is, the
client acknowledges the release of its current dataspace by requesting a
new dataspace via the 'Framebuffer::Session::dataspace()' function.
Fixes#1057
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 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.
Base libraries are already contained within ldso.lib.so. Remove unnecessary
filtering from 'dep_lib.mk', make ldso depend on base libs.
Issue #1017
Issue #989
For a main thread a thread object is created by the CRT0 before _main gets
called so that _main can already run in a generic environment that, e.g.,
catches stack overflows as a page-fault instead of corrupting the BSS.
Additionally dynamic programs have only one CRT0 - the one of the LDSO -
which does the initialization for both LDSO and program.

With this patch, the liquid_fb title bar height gets reserved at the top of the
screen, so if a Qt application wants to position a window at (0,0), there's
still enough space to show the title bar above.
Issue #1054.
On 64-bit platforms Qt's JavaScript engine tries to reserve 1GiB of
virtual memory via 'mmap()', to be backed by physical memory on demand.
Genode's 'mmap()' implementation currently does not support on-demand
allocation of physical memory and tries to allocate the whole amount at
once, which is usually far more than needed.
With this patch, the amount to be reserved gets decreased to 32MiB.
Fixes#1041.
