Re: [lwip-users] netconn_delete and _recv not thread safe

[Rob Duncan]

This is possibly related to an older thread:

http://www.mail-archive.com/address@hidden/msg01479.html

I'm seeing a similar problem (under eCos) where I'm in the middle of netconn_delete and a RST for that connection arrives.  I end up with an extra message in conn->mbox (the one from lwip_close(), and another that err_tcp() adds for the RST).  This means that the mbox is not empty when sys_mbox_free() is called, and I get an assertion failure.

Does this analysis seem right?  And if so what would be the best way of correcting the problem?  I'm a bit fuzzy on how thread safety is supposed to be done here, so any hints or pointers to more information would be very useful.

Thanks,

Rob.
