The racoon session code copies an fd_set from one variable into another
prior to calling select. That works well for simple structures.
In libbsd we have to allocate fd_sets instead of using fixed structures
to avoid a problem with file numbers bigger than FD_SETSIZE. The simple
assignment didn't work in that case.
This patch makes sure that a memcpy is used instead.
Close#4914
Under unknown conditions the receive path ended up in a frozen state.
In this state, the DMA and driver descriptor head were equal and all
receive descriptors had the used bit set. So, the DMA was unable to
store received frames. However, the receive daemon was never woken up
to refill the receive buffers. It seems that the RXUBR interrupt can be
used to recover from this state.
Update #4651.
Do not use the interface mutex in the receive loop. Avoid multiple
reads of DMA descriptor words. Use a compile-time constant for the
receive DMA descriptor count to simplify calculations.
Update #4651.
Use the transmit interface handler to avoid a transmit task/interrupt.
Use a compile-time constant for the transmit DMA descriptor count to
simplify calculations.
Update #4651.
The pppstart expected that a driver write would somehow magically
process all data passed to the write function. Because ppp disables all
buffering that originally has been in termios, that assumption is not
true for all but polled drivers.
With this patch, the pppstart now gets and processes the feedback that
is returned from the driver via rtems_termios_dequeue_characters.
Fixes#4494
- Add PCI IO region support
- Add support map buffers to PCI address space
- Add BSP conditional IO space support. Some PC implementations
have PCI IO space mapped differently to memory space and this needs
to be reflected in the busspace.
- Include bsp.h to pick per BSP configuration.
Closes#4514
setkey uses pfkey_open to open a socket. But setkey doesn't close the
socket.
The libipsec functions are used only by user space applications (setkey
and racoon). Adding the wrapper for socket makes sure that the opened
socket is registered and closes if the application exits.
Fixes#4404
