dtrace and follow fork
I am trying to use dtrace to trace all sscanf calls. I am able to use pid provider for this. But my application forks off children at times to handle requests.

I have tried using the "create" probe but that did not help.

monitoring tcp writes
i''m using the following probe to calculate how many bytes are being written by tcp write calls, by process and total: fbt:ip:tcp_output:entry { this->tcpout_size = msgdsize(args[1]); @tcpout_size[execname] = sum(this->tcpout_size); @tcpout_size["TOTAL_TCP_OUT"] = sum(this->tcpout_size); } I run this probe for N seconds. I suppose that if i get the tcpout_size["TOTAL_TCP_OUT"] value and...

...p disclosure, or further impact was found in setsockopt(). The function call is normally restricted to root, however some processes with cap_sys_admin may also be able to trigger this flaw in privileged container environments. (CVE-2016-4998, Moderate) * A use-after-free vulnerability was found in tcp_xmit_retransmit_queue and other tcp_* functions. This condition could allow an attacker to send an incorrect selective acknowledgment to existing connections, possibly resetting a connection. (CVE-2016-6828, Moderate) Bug Fix(es): * When parallel NFS returned a file layout, a kernel crash sometime...

UDP for data?
Hi, I'm very interested in making SSH use UDP for large data chunks. Maybe you know FASP (https://en.wikipedia.org/wiki/Fast_and_Secure_Protocol), but that is proprietary, although the website says it's based upon open source methods. Is it possible to make openssh work with UDP for this purpose? Thanks in advance, Stef Bon
