Do not use two times the RTT for the lifetime of links but use it as
it is configured to simplify the usage of the router. Internally, use
Microseconds/Duration type instead of plain integers.
Ref #2490
The remote shell facilities are past deprecation and there is an
obligation to prevent their use rather than to support them. This patch
removes the related function definitions from 'unistd.h', which have not
been been included in the Genode libc ABI regardless.
Fix#2530
Remove getaddrinfo and freeaddrinfo from the Libc::Plugin and get rid of
the extra libc_resolv library. Remove getaddrinfo/freeaddrinfo symbol
hiding patch for FreeBSD sources. Remove libc_resolv from Makefiles and
run scenarios.
Fix#2273
This recipe copies the entire stdcxx library into the API archive, which
is an interim solution until we introduce a proper ABI for stdcxx. With
this current version, every user of the stdcxx ABI will implicitly build
the stdcxx library.
The timer driver should always be of the highest priority to avoid
problem with timers that have low max-counter values like the PIT
with only 53 ms.
Ref #2400
Add a "writeable" policy option to the ahci_drv and part_blk Block
servers and default from writeable to ready-only. Should a policy
permit write acesss the session request argument "writeable" may still
downgrade a session to ready-only.
Fix#2469
The files are generated via flex and bison. Until now, this step was
performed when preparing the libc port. Unfortunately, the generated
files have subtle differences depending on the flex/bison versions
installed in the host. For example, the bison version number appears in
the generated code. This, in turn, breaks the hash mechanism of the
depot where a src/libc archive ends up being slightly different when
created on different hosts.
By moving the code generation to the build stage, the src/libc archive
merely contains the nslexer.l and nsparser.y source files but not the
generated files.
The VFS library can be used in single-threaded or multi-threaded
environments and depending on that, signals are handled by the same thread
which uses the VFS library or possibly by a different thread. If a VFS
plugin needs to block to wait for a signal, there is currently no way
which works reliably in both environments.
For this reason, this commit makes the interface of the VFS library
nonblocking, similar to the File_system session interface.
The most important changes are:
- Directories are created and opened with the 'opendir()' function and the
directory entries are read with the recently introduced 'queue_read()'
and 'complete_read()' functions.
- Symbolic links are created and opened with the 'openlink()' function and
the link target is read with the 'queue_read()' and 'complete_read()'
functions and written with the 'write()' function.
- The 'write()' function does not wait for signals anymore. This can have
the effect that data written by a VFS library user has not been
processed by a file system server yet when the library user asks for the
size of the file or closes it (both done with RPC functions at the file
system server). For this reason, a user of the VFS library should
request synchronization before calling 'stat()' or 'close()'. To make
sure that a file system server has processed all write request packets
which a client submitted before the synchronization request,
synchronization is now requested at the file system server with a
synchronization packet instead of an RPC function. Because of this
change, the synchronization interface of the VFS library is now split
into 'queue_sync()' and 'complete_sync()' functions.
