* Update of network driver from Erik Ivanenko <erik.ivanenko@utoronto.ca>.Joel Sherrill1999-01-206-165/+399
| | | | | | | | | | | Comments follow: Here is the contents of the network directory of the i386ex BSP. The reset function has been recently added, and tested through a command line interface. A reset event to the reset thread to reset the NIC. This is done when the ISR detects that the NIC is in an invalid state. It has not been tested "in real life" since the board has not seen an invalid state since the reset function was implemented.
* 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.

Just let me > know which you think is more correct and the source will change. :) Hmmm, just removing the '~' should be OK. DEBUG_puts() seems to be the only user of ERC32_Restore_interrupt() anyway ...
* Patch from Chris Johns <ccj@acm.org> to get around a C++ problem with psim.Joel Sherrill1999-01-051-13/+13
| | | | | | | | | | | | | | | | | | This problem should and likely was occurring with other BSPs. This is from Chris' email: I had a look in the psim bsp for the older snapshot I have and it looks like you are using the `libbsp/shared/main.c' and this is known to work. I have just built the powerpc tools, and compiled the bsp. I have not added the linker command file patch so got the list of linker warnings. It looks to me like a compiler bug. The `main' call is being inlined and when that happens the special code to call `__eabi' is not being added to the inlined version. I have attached a patch which places `main' after `boot_card' and a call to main is now generated. I have not tested it but it should work. I also include a dump of `boot_card' and `main' showing the bug.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
