* Patch from Eric Norum <eric@skatter.usask.ca> to make m68360.h usableJoel Sherrill1999-01-201-357/+366
| | | | | | | | outside RTEMS. Comment: I found a couple of places other than RTEMS where I'd like to use the declarations supplied in m68360.h. To make this easier to do, I've redone the declarations in m68360.h to use standard C types.
* More general fix based on bug report and patch from Ian Lance TaylorJoel Sherrill1999-01-2014-2/+42
| | | | | | | | | | <ian@airs.com> to fix this problem: There is a small bug in __rtems_close in c/src/lib/libc/libio.c. It does not check whether the file descriptor it is passed is open. This can cause it to make a null dereference if it is passed a file descriptor which is in the valid range but which was not opened, or which was already closed.

| | | | | | | | getting the spurious trap handling to work required a couple more fixes - I have attached a patch against rtems-4.0.0 with the necessary changes. I also added functionality so that the address of the trapped instruction is reported and in case of a data access error, the data address is also reported.

DEBUG_puts() seems to be the only user of ERC32_Restore_interrupt() anyway ...

* Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de> to reorganize POSIXJoel Sherrill1998-12-152-2/+2
| | | | | | | | | | | | | | | | | | | | | | directory in preparation for automake: Here is a shell script which reorganizes some parts of the exec/posix source tree. This shell scripts moves include files below exec/posix to different locations than now. It doesn't yet apply automake, but still use the old autoconf configuration scheme. It doesn't influence the build scheme at all (unless I corrupted something), only the location of the header files is different, which would ease applying automake later. The purpose of this shell script is to demonstrate the style of structural changes I would like to see in rtems in near future to prepare a smooth transition to automake. Then CC could pickup rtems' header files from their location inside of the source tree in future, instead of the build tree as it is done now. In case you would accept this patch/script, there would be more similiar ones to come.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From: Eric Norum <eric@skatter.usask.ca> Date: Sat, 5 Dec 98 13:20:51 -0600 What do you think of this patch? It implements your `tap' suggestion in a way that adds support for all ethernet devices with no driver modifications. I also added a return value from the tap function. If the return value is zero, the packet will be passed up the chain as usual. If the return value is non-zero the mbuf holding the packet will be freed and the packet will be dropped. If you like it, please submit it to Joel. I guess there needs to be an addition to the network documentation describing the additional ioctl's -- and a big warning that the tap function is called from a context that holds the network semaphore. Here is Eric's patch. I've tested it a bit, and made a couple of trivial changes. This is certainly better than mine: it should work for all Ethernet drivers. ================================================== The only concern I have about this patch is that the tap function may want to fiddle with the mbuf, calling functions like m_pullup and the like. If those force the networking code to rearrange the mbuf structure, then the caller's call to m_freem may crash. I don't know if this is a realistic concern--I don't know enough about the mbuf layer.

* Patch from Ian Lance Taylor <ian@airs.com>:Joel Sherrill1998-12-073-5/+12
| | | | | | | | | | | | | RTEMS permits using the SO_SNDTIMEO and SO_RCVTIMEO socket options to set a timeout for most socket I/O operations. However, in RTEMS 4.0.0, those options do not affect connect or accept. I don't know of any way to put a timeout on those calls in RTEMS 4.0.0; can anybody point to one. Since it is frequently useful to have a timeout on accept, and sometimes useful to have a timeout on connect shorter than the BSD system default of 75 seconds, the following patch causes SO_RCVTIMEO to affect connect and accept.

* Patch from Emmanuel Raguet <raguet@crf.canon.fr> to add remote debug serverJoel Sherrill1998-12-0310-19/+1491
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and RPC support to RTEMS. Thanks. :) Email follows: Hello, For Xmas, here is the Remote Debugger on RTEMS ! Here are 2 patches for the Remote Debugger on RTEMS for pc386 from Linux host : - one for RTEMS it self, - one for GDB-4.17. 1/ RTEMS patch -------------- This patch adds 2 libraries : - a simplified SUN RPC library - the Remote Debugger library The configuration command is the following : ../rtems4/configure --target=i386-rtemself --enable-rtemsbsp=pc386 --enable-rdbg The SUN RPC library is built only if networking is set. The RDBG library is built if networking and enable-rdbg are set. The function used to initialize the debugger is : rtems_rdbg_initialize (); A special function has been created to force a task to be in a "debug" state : enterRdbg(). The use of this function is not mandatory. 2/ GDB-4.17 patch ----------------- This patch create a new RTEMS target for GDB-4.17. The configuration command is the following : ./configure --enable-shared --target=i386RTEMS To connect to a target, use : target rtems [your_site_address] Then, attach the target using : attach 1 And... Debug ;) You can obtain the original GDB-4.17 on ftp://ftp.debian.org/debian/dists/stable/main/source/devel/gdb_4.17.orig.tar.gz This has been tested from a Debian 2.0.1 linux host.

* Added base version of file system infrastructure. This includes a majorJoel Sherrill1998-11-2398-644/+8995
| | | | | | | | | | | | | | | | | | | | | | | | overhaul of the RTEMS system call interface. This base file system is the "In-Memory File System" aka IMFS. The design and implementation was done by the following people: + Joel Sherrill (joel@OARcorp.com) + Jennifer Averett (jennifer@OARcorp.com) + Steve "Mr Mount" Salitasc (salitasc@OARcorp.com) + Kerwin Wade (wade@OARcorp.com) PROBLEMS ======== + It is VERY likely that merging this will break the UNIX port. This can/will be fixed. + There is likely some reentrancy/mutual exclusion needed. + Eventually, there should be a "mini-IMFS" description table to eliminate links, symlinks, etc to save memory. All you need to have "classic RTEMS" functionality is technically directories and device IO. All the rest could be left out to save memory.

* Patch from Eric Norum <eric@skatter.usask.ca>:Joel Sherrill1998-11-199-175/+243
| | | | | | | | | | | | | | | 1) Socket timeout field changed from `short' to `long'. This makes longer timeouts possible. With a 1 kHz system clock the old system allowed timeouts only up to a little over 30 seconds! This change is a slightly cleaned-up version of the patch proposed by Ian Lance Taylor. 2) Major changes to BOOTP/DHCP reply handling. Now supports much of RFC2132. These changes were done at the request of, and with the assistance of, Erik Ivanenko. If you're making changes, you might want to change the network supplement Essentially just do a global search and replace of BOOTP with BOOTP/DHCP.
* changed version to 4.0.0-AFCCJoel Sherrill1998-10-292-2/+2
