Issue #814
This avoids a deadlock if during issuing a printf the low level IPC fails.
. Printf uses an address space local lock and if we are trying again
to make a printf we deadlock forever ...
This patch eliminates the "no attachment at..." warnings, which
were caused by a use-after-free problem of dataspaces. When a
dataspace was destroyed, the users of the dataspace were not
informed and therefore could not revert possible attachments to
RM sessions. The fix introduces a callback mechanism that allows
dataspace users (i.e., RM regions) to register for the event that
a dataspace vanishes.
The following types of dataspaces are handled:
* RAM dataspaces
* ROM dataspaces
* The process binary
* The binary of the dynamic linker
* Args dataspace
* Sysio dataspace
* Env dataspace
* managed RM dataspaces
The handling of ROM dataspaces is still not complete. When forking,
the ROM dataspace of the parent process gets just reused without
creating proper meta data ('Dataspace_info') for the forked process.
Similar issues might arise from other special dataspaces (e.g.,
args, env, sysio).
This patch removes all "no attachment at..." warnings except for
one (an attachment at 0).
Issue #485
The 'check_dev_tty()' function calls 'ttyname()', which calls the pthread
stub function 'pthread_main_np()', which prints a 'not implemented'
message. Calling 'check_dev_tty()' doesn't seem to be necessary, so this
patch removes the call.
Issue #815.
With this patch, the 'not implemented' messages of the pthread function
stubs always get printed to the Genode log console instead of stdout.
Issue #815.
Previous commit denies the creation of regions larger then the dataspace.
Noux does it by setting the default size to the dataspace size without
subtracting the offset.
Fixes#591
The rm_session implementation expects that offset + size must be
part of one dataspace. Unfortunately the parameters are not checked
properly during an rm::attach.
During an detach memory behind the actual region can be unmapped by such
bogus region entries.
Issues #591
Since RM sessions can be used as dataspaces and dataspace sizes are
supposed to have page granularity, RM session sizes should have page
granularity, too.
Fixes#799.
Forgetting to restore the old utcb content results in hard to debug bugs.
Save only the amount of word items which are actually on the UTCB.
Issue #806
Avoids the message
cxx: operator delete (void *) called - not implemented. A working implementation is available in the 'stdcxx' library
during a " new ..." which causes exceptions. Happens for seoul in disk.cc
Issue #806
The Rpc_exit call is delivered via RPC which results in a deadlock
if the Rpc_entrypoint has not been started yet. To prevent this
situation we active the Rpc_entrypoint explicitly before we call
Rpc_exit.
Fixes#811.
'alloc_skb' might now fail, the Nic component will then send a 'packet
available' signal and return. Fix broken SKB list implementation as well as
completely bogus initialization of SKBs.
Related to #778.
In this case "mv A B" works slightly different than "cp A B; rm A" as
symbolic links come into play. The statements should copy the contents
of A into the symboliv link at B (preserving it as is) and remove A. The
mv would replace the link B by the binary A.
Fixes#805.
