...ew intrinsic: void @llvm.invariant(i1 %cond) which declares that the %cond is defined to be true. First, we need to make sure that instructions that contribute only to forming the invariant conditions don't interfere with optimization and code generation. We'll call these instructions 'ephemeral' (this was Chandler's idea). An analysis pass can walk instructions starting from the @llvm.invariant calls and record those instructions as ephemeral those used only by other ephemeral instructions (the invariant call is also ephemeral). This analysis pass will be used by: - The inliner (...

...e) with kernel 3.10.0-514.16.1.el7.x86_64 Using iperf for bond benchmarking, and opening several sockets, I noticed a strange behavior. My Centos using iperf as a client to connect to an iperf server (running either CentOS or Debian) requesting N parallel TCP connections. I notice that the local ephemeral ports used are not consecutive and are always even ports numbers. This can change to "only odd ports numbers" depending on the setting net.ipv4.ip_local_port_range, but basically, the idea is the Centos kernel does "+2" when finding a local port for socket, not doing +1.

...I always see DTLS ECDH initialized (automatic), faster PFS enabled any idea? Thanks! res_rtp_asterisk ------------------ * The DTLS part in Asterisk now supports Perfect Forward Secrecy (PFS). Enabling PFS is attempted by default, and is dependent on the configuration of the module using TLS. - Ephemeral ECDH (ECDHE) is enabled by default. To disable it, do not specify a ECDHE cipher suite in sip.conf, for example: dtlscipher=AES128-SHA - Ephemeral DH (DHE) is disabled by default. To enable it, add DH parameters into the private key file, e.g., sip.conf dtlsprivatekey. For example: openssl dhparam...

...ts behavior given <args>? If so, then I think this is pretty bad. If we ever want to parallelize function passes, then they can't inspect the innards of other functions. So this would significantly constrain the utility here. Also, this would create uses of the arguments that were "ephemeral" uses. It's not clear how that is better than any of the other proposals to represent constraint systems in the IR via "ephemeral" uses. -------------- next part -------------- An HTML attachment was scrubbed...

This makes the amount of time between starting the daemon and the creation / update of the sshd.pid file variable, and can cause a race condition with e.g. /sbin/init.d scripts which start the daemon and then want to check to see that the start was successful. Please move the sshd.p...

...0-length recv. The DOS box flails away attempting to reconnect forever, and the server never seems to get any type of signal that the DOS box is attempting to reconnect. Possibly relevant facts: - The DOS box uses the same local port (1025) every time it tries to connect. It does not use a random ephemeral port. - The exact same code was tested on a CentOS 6.5 and 6.6 box, resulting in the described behavior. The boxes were identical clones except for the O/S upgrade. - The Python interpreter was not changed during the upgrade, because I run this code using my own 2.7.2 install. However, both glibc a...

Hi! Previously in the "Add a 'notrap' function attribute?” thread we had discussed a way to use meta-data to specify that a load does not trap under certain conditions. Andy and Hal and I talked about this more in private and I just wanted to summarize what I think we arrived at. First I’ll summarize the original !notrap meta-data, then I’ll just mention why it’s hard to get it

...ty adjusts the permanent configuration, the one that will be applied at startup. Another changes the current running environment without altering the startup config. From a sysadmin point of view this is desirable since changes to a running system are often performed for empirical testing. Leaving ephemeral state changes permanently fixed in the startup config could, and almost certainly would eventually, lead to serious problem during a reboot. Likewise, immediately introducing a state change to a running system when reconfiguring system startup options is just begging for an operations incident rep...
