Is there a problem connecting a client running 2.1.4 (the one with polarssl) to a server running 2.0.9?
How would the flow typically be? I see client sending P_CONTROL_HARD_RESET_CLIENT_V2, and then immediately starts the ssl session (which writes the client hello, but fails to read the server hello). Shouldn't it be that after sending the P_CONTROL_HARD_RESET_CLIENT_V2 the client will need to wait for P_CONTROL_HARD_RESET_SERVER_V2? I do see the P_CONTROL_HARD_RESET_SERVER_V2 comes after some time, but there is always an attempt to start the ssl session from the client side.

I do have a problem with returning structures with my 16 bit machine, seems some of the data not being copied (probably need to define far segment). -----Original Message----- From: Fabian Knittel [mailto:fabian.knit...@avona.com] Sent: Monday, December 12, 2011 12:11 AM To: Tiran Kaskas Cc: openvpn-devel@lists.sourceforge.net Subject: Re: [Openvpn-devel] Problem with alloc_buf_gc function Hi Tiran, Am 11.12.2011 21:57, schrieb Tiran Kaskas: > Looking into the function alloc_buf_gc() in file buffer.c, it returns > a struct buffer, which seems to me is allocated on the stack, which is > causing an issue, I believe, since the function calling alloc_buf_gc() > will work on a buffer which becomes garbage. 'alloc_buf_gc()' is returning 'buf' (of type 'struct buffer') by value, not by pointer, so there is no problem here. If it were returning 'buf' by pointer your observation would be correct. (In C++ a typical mistake would be to return 'buf' by reference.) The function calling 'alloc_buf_gc()' will copy the contents of 'buf' to its local instance of 'struct buffer' before continuing. (An optimised build might even eliminate the copy.) Are you observing a specific problem with buffers or did you just happen to stumble over this piece of code?
