A question about shmat and processes

Reddit - Mon, 2017-03-27 19:46

Hey guys,

I have a question about shmat, the function used for linking a proccess to a shared memory segment.

I have a program that goes like this:

int* segment; void proccess() { //... } int main() { int Id = shmget(IPC_PRIVATE, sizeof(INT), 0600); segment = shmat(Id, NULL, 0); if (fork() == 0) { proccess(); exit(0); } if (fork() == 0) { proccess(); exit(0); } }

My questions are:

1) How can the two forked processes access segment? Shouldn't I call fork in my proccess?

2) Do these forked processes run concurrently in memory? ps says they do.

Thanks in advance!

  • Hurrah! Dash to Dock Now Supports GNOME 3.24

    The Dash to Dock GNOME Shell Extension has been updated to support GNOME 3.24, and improves its app launch keyboard shortcut feature.

  • openSUSE Tumbleweed Is the First to Offer the GNOME 3.24 Desktop Environment

    openSUSE Project's Dominique Leuenberger was proud to announce the availability of the recently released GNOME 3.24 desktop environment into the software repositories of the openSUSE Tumbleweed rolling release.

    According to the developer, and to our knowledge, openSUSE Tumbleweed is now the first GNU/Linux distributions to offer the GNOME 3.24 packages to their users. We know that openSUSE is a distro mostly oriented towards the KDE Plasma desktop, but support for GNOME is provided at the same level of quality.

Linux Action Show ends after 10-year run

TuxMachines - Mon, 2017-03-27 17:56

This past Sunday, Jupiter Broadcasting announced the Linux Action Show—one of the longest-running podcasts in the Linux world, which has aired almost continuously since June 10, 2006—is coming to an end and closing down production.

Over a decade. That is a seriously good run for any show—podcast, TV, radio or otherwise. When I and my co-host created the Linux Action Show (typically abbreviated as LAS) nearly 11 years ago, we had no idea it would last this long. Nor did we have any idea of how far it would grow.

Process startup testing

Reddit - Mon, 2017-03-27 17:54

I'm seeking a method for running tests on our custom Linux OS, developed using the Yocto Project, that will help us gauge process startup time. Preferably this will be done through forking.

Does anyone have any recommendations on open source test platforms that can help test this?

We've been looking through phoronix Test Suite though there seems to not be any of use there.

Tool to monitor process network connections?

Reddit - Mon, 2017-03-27 17:41

Short version: I am looking for a linux utility similar to the windows tcpview utility from sysinternals.

Long version:

I have an odd problem with an application. We have a commercial application that replicates its proprietary database across a network connection. This is running on two suse enterprise servers. The servers each have 10Gb connections to their local switches, but the switches only a have a 1Gb link between them (this is across datacenters). They connect at layer 2 (they are on the same subnet).

The replication processes consistently transfer around 200GB of data, then errors out. After sending numerous debug logs and wireshark packet captures to the vendor, their opinion is "network error". They base this off the numerous dropped packets and retransmission shown in the packet captures. I can't get them to understand that you'd expect to see lots of dropped packets with a 1Gb link in between two 10Gb links.

iperf3 shows a continuous 900Mb or better throughput between the two systems. I can successfully sftp a 250GB file both ways. No other systems that operate across the two datacenters are having problems, including backups which send a considerable amount data across every day (Yes, I have tried the replication with backups quiesced) .

I am looking for some sort of utility that can monitor the vendor processes and show me how they are opening sockets to each other (what options are used), and whether the socket is erroring out, or if the application is just getting confused somehow and closing the socket. I am hoping that the vendor is doing something goofy with tcp options in an attempt to boost performance.
