But I can see your point now, if it is an OpenSSL problem you are pretty
much stuck. For example if OpenSSL uses select() to sleep for
/dev/random but your application is already into the 1500th active file
descritor. Then OpenSSL is pretty much hosed for using select() inside
itself, infact it should do a sanity check internally otherwise random
corruption/crashes will occur because FD_SET() may scribble on memory.
Heh, nice... maybe this is a candidate:
rand/rand_unix.c:211: if (select(fd+1,&fset,NULL,NULL,&t) < 0)
You are safe if you don't increase your ulimit -n above the standard
default of 1024. Above that OpenSSL may not be safe anymore. Try
adding stack padding around the "fset" variable and see if your crashes
go away to prove the solution.
Then maybe we can patch this for a poll() on platforms that support poll
and do a sanity check of:
if(fd > __FD_SETSIZE) { do_error(); }
on platforms that dont.
