[OpenSIPS-Devel] [OpenSIPS-Users] [Releases] Scheduling OpenSIPS 1.10 beta

[Vlad Paiu]

Hello Saúl,

The TCP reads optimizations have already been pushed to OpenSIPS trunk ( 
in commits [1] and [2] )
The read improvements cover :
     - the TCP read buffer has been moved from a per connection basis to 
a per process basis
         Advantages here cover : less memory used by OpenSIPS for a 
large number of processes ( 64 KB of SHM memory saved per TCP connection )
                                               : faster acceptance of 
new TCP connections ( less SHM memory that needs to be allocated )
     - make the TCP read part in OpenSIPS less vulnerable to attacks
         Improvements here are : put a limit on max number of chunks 
that a TCP message can arrive in ( thus blocking attacks where the 
attacker would open                     the connection and then just 
push SIP messages byte by byte )
                                                : put a limit on max 
number of seconds that a TCP message can arrive in

For the TCP write part, we're now finalizing asynchronous writing ( both 
for actual writes and also for connects ) - will be implementing by 
moving the currently blocking writes and connects attempts from the TCP 
children to a separate process.
