There is a bug in the LwIP VFS plugin, the chained buffers used by Lwip
use sizes expressed in sixteen bits, and under conditions such as a read
of 1<<16 the higher bits are lost and the plugin performs a zero length
read, and the application interprets this as a closed connection.
Fix#2947
A 'QThread' can be reused when its execution is finished by calling
'QThread::start()' again. Before this commit, this created a new Genode
thread, but did not destroy a previously finished Genode thread first.
Fixes#2928
This patch reintroduces the LwIP stack to libc as a VFS plugin
implementing the socket_fs interface. Rather than use LwIP's socket
emulation layer this plugin interfaces directly to LwIP raw API and is
single threaded.
The internal TCP parameters of the stack are untuned.
Fix#2050Fix#2335
Calling 'handle_io_response()' in a regular VFS function (in contrast to a
post-signal hook) can cause problems if the caller of the VFS function holds
a lock which prevents the io response handler from returning.
With this commit, the user of the VFS becomes responsible for unblocking
threads which might be blocking after a failed 'queue_read()', 'queue_sync()'
or 'write()' call.
Fixes#2896
- initialize the stack size attribute with `Libc::Component::stack_size()`
as default value
- remove the possibly uninitialized `pthread` member from the attribute
structure and obtain current attribute values in the
`pthread_attr_get_np()` function, where the `pthread` object reference
is given as argument
- let each thread obtain its stack address and actual stack size at thread
start to have the information available for other threads
Fixes#2865
The libc will now use the file given by the 'nameserver_file' attribute
to get the DNS nameserver address instead of reading '/etc/resolv.conf'.
It defaults to '/socket/nameserver' which is the common location when
using the lxip VFS plugin. As a constraint the libc will read the first
line and expects the nameserver address without any keywords in front of
it.
Fixes#2861.
- support saving of files with no file name extension
- make the the "All Files (*)" file selection filter the default to see
configuration files immediately
Fixes#2844
Properly initialize and reset the _owner member, otherwise
correlating the unlock operation with the respective read/write
lock does not work.
Move locking the _nbr_mutex in the unlock operation after the
owner check. Otherwise, a reader holding that mutex and waiting
for the write lock would deadlock a writer trying to unlock the
_global_mutex.

Rename LwIP library in preparation for removal of LwIP libc plugin. The
current LwIP library will be replaced with a new version stripped of its
synchronous socket support. The next version will be incompatible with
the current, so removing 'lwip.lib.so' completely for a period makes it
easy to identify legacy users.
Fix#2797
Generic code that operates over both UDP and TCP sockets might use
'sendto', but in the case of TCP the destination address ought to be
safely discarded. This seems to be the case for certain DNS software
that operates over both UDP and TCP.
Fix#2807
issue #2791
pthread_attr is not associated with any thread, the statistics must be
gathered at runtime, while 'pthread_attr_get_np' may retrieve attributes
by from any thread. Addtionally, the attributes given to
'pthread_create' will most likely be deleted after the creation call.
Socket_fs sockets are now created each time a 'new_socket' control file
is opened, not each time a 'new_socket' file is read. When a handle on a
'new_socket' file is closed the socket and its socket files are
destroyed. The accept control file on a listening socket reads "1" or
reads nothing to indicate a client connection is queued. Client sockets
are accepted by opening an 'accept_socket' file in the listen socket
directory. This file behaves like the aforementioned 'new_socket' file.

This commit changes the 'Input::Event' type to be more safe and to
deliver symbolic character information along with press events.

Reduce the size and forward compatibility of VFS file-system
constructors by passing an object holding accessors for 'Genode::Env',
'Genode::Allocator', response handlers, and the root file-system.
Fix#2742
In other words: Loosen the former property that suspend can only be
called from the first user stack and, thus, enable additional user
stacks, e.g., in coroutine libraries.
Fix#2737
This patch enables the use of the VFS from VFS plugins by passing a
reference of the root directory to the constructors of file-system
instances. Since it changes the signature of 'Vfs::Dir_file_system',
any code that uses the VFS directly requires an adaptation.
Fixes#2701
Link the EGL library with Mesa. SDL's `GL_GetProcAddress` now calls
`eglGetProcAddress` rather than lookup procedures directly in the Mesa
library.
Components may still wish to list 'mesa_api' in LIBS to access OpenGL
headers.
Fix#2711
This prevents diagnostic messages like
Error: partial write detected 0 vs 31
for writes into already released socket directories due to a still-open
handle to the socket data file.
The new 'verify' component facilitates the code of GnuPG to verify
detached OpenPGP signatures against public keys.
Since GnuPG depends on libgcrypt and libgpg-error, the patch adds these
libraries to the libports repository.
Fixes#2640
This is a follow-up commit to "Increase default warning level", which
overrides Genode's new default warning level for targets contained in
higher-level repositories. By explicitly whitelisting all those targets,
we can selectively adjust them to the new strictness over time - by
looking out for 'CC_CXX_WARN_STRICT' in the target description files.
Issue #465
Stdin, stdout, and stderr are mapped to descriptors 0, 1, and 2
respectively. If these first three descriptors are not allocated before
the application becomes active then normal files and sockets can be
opened under these numbers, potentially causing unexpected application
behavior.
Fix#2628
This patch makes the creation of the libc's timer session depend on
whether or not the 'rtc' attribute of the <libc> configuration is
defined. If not configured, 'clock_gettime' returns 0.
Fixes#2625
The synchronization with the ACPI driver is not needed when starting
acpica at a later stage. It could already be disabled via the
'acpi_ready="yes"' config attribute. However, acpica still
unconditionally requests the so-called "Acpi" service, which is an
alias for the platform_drv's "Platform" service. This patch disables the
use of this alias when the 'acpi_ready' synchronization is disabled.
This makes '/' and the actual root of VFS distinguishable. A VFS root
may contain one ore more '/' entries for each file system. 'opendir' for
the VFS root opens all file systems via 'open_composite_dir', while
'opendir' for '/' only returns a VFS handle.
Fixes#2569
