fedora 14 kernel performance with ip forwarding workload
by Jesse Brandeburg 05 Jun '15

05 Jun '15

The other day I was running the stock fedora kernel on my ip forwarding setup, to see what the performance was, and the performance wasn't very good. system is S5520HC dual socket 2.93GHz Xeon 5570 (Nehalem) with 3 quad port 82580 adapters (12 ports). Traffic is bidirectional 64 byte packets being forwarded and received on each port, basically port to port routing. I am only using 12 flows currently. The driver is igb, and I am using an affinity script that lines up each pair of ports that are forwarding traffic into optimal configurations for cache locality. I am also disabling remote_node_defrag_ratio to stop cross node traffic. With the fedora default kernel from F14 it appears that CONFIG_NETFILTER=y means that I cannot unload all of netfilter even if I stop iptables service. perf showed netfilter being prominent, and removing it gives me much higher throughput. Is there a reason CONFIG_NETFILTER=y ? Isn't it a good thing to be able to disable netfilter if you want to? Jesse

[PATCH v3] kernel.spec: let flavors/variants end with "+$flavor" in the uname
by Harald Hoyer 22 Jul '13

22 Jul '13

From: Harald Hoyer <harald(a)redhat.com> This patch changes the version of kernel flavor/variants to end in "+$flavor" instead of ".$flavor". This makes it easier to detect a flavor and a parser can separate it from the architecture. With that change we can correct kernel-install (of systemd) to call new-kernel-package with --package kernel-$flavor, because the $flavor can easily be extracted from the version string. --- Rebased for current git. commit 69c0bf478219b2fbb38fb3c707b220b75bfa4129 Date: Wed Jun 26 07:50:55 2013 -0400 kernel.spec | 74 ++++++++++++++++++++++++++++++------------------------------- 1 file changed, 37 insertions(+), 37 deletions(-) diff --git a/kernel.spec b/kernel.spec index 27fd3f2..ecce9f2 100644 --- a/kernel.spec +++ b/kernel.spec @@ -473,17 +473,17 @@ Summary: The Linux kernel # %define kernel_reqprovconf \ Provides: kernel = %{rpmversion}-%{pkg_release}\ -Provides: kernel-%{_target_cpu} = %{rpmversion}-%{pkg_release}%{?1:.%{1}}\ +Provides: kernel-%{_target_cpu} = %{rpmversion}-%{pkg_release}%{?1:+%{1}}\ Provides: kernel-drm = 4.3.0\ Provides: kernel-drm-nouveau = 16\ Provides: kernel-modeset = 1\ -Provides: kernel-uname-r = %{KVERREL}%{?1:.%{1}}\ +Provides: kernel-uname-r = %{KVERREL}%{?1:+%{1}}\ Provides: kernel-highbank\ -Provides: kernel-highbank-uname-r = %{KVERREL}%{?1:.%{1}}\ +Provides: kernel-highbank-uname-r = %{KVERREL}%{?1:+%{1}}\ Provides: kernel-omap\ -Provides: kernel-omap-uname-r = %{KVERREL}%{?1:.%{1}}\ +Provides: kernel-omap-uname-r = %{KVERREL}%{?1:+%{1}}\ Provides: kernel-tegra\ -Provides: kernel-tegra-uname-r = %{KVERREL}%{?1:.%{1}}\ +Provides: kernel-tegra-uname-r = %{KVERREL}%{?1:+%{1}}\ Requires(pre): %{kernel_prereq}\ Requires(pre): %{initrd_prereq}\ Requires(pre): linux-firmware >= 20120206-0.1.git06c8f81\ @@ -953,7 +953,7 @@ AutoReqProv: no\ %description -n %{name}%{?1:-%{1}}-debuginfo\ This package provides debug information for package %{name}%{?1:-%{1}}.\ This is required to use SystemTap with %{name}%{?1:-%{1}}-%{KVERREL}.\ -%{expand:%%global debuginfo_args %{?debuginfo_args} -p '/.*/%%{KVERREL}%{?1:\.%{1}}/.*|/.*%%{KVERREL}%{?1:\.%{1}}(\.debug)?' -o debuginfo%{?1}.list}\ +%{expand:%%global debuginfo_args %{?debuginfo_args} -p '/.*/%%{KVERREL}%{?1:\+%{1}}/.*|/.*%%{KVERREL}%{?1:\+%{1}}(\.debug)?' -o debuginfo%{?1}.list}\ %{nil} # @@ -965,9 +965,9 @@ This is required to use SystemTap with %{name}%{?1:-%{1}}-%{KVERREL}.\ Summary: Development package for building kernel modules to match the %{?2:%{2} }kernel\ Group: System Environment/Kernel\ Provides: kernel%{?1:-%{1}}-devel-%{_target_cpu} = %{version}-%{release}\ -Provides: kernel-devel-%{_target_cpu} = %{version}-%{release}%{?1:.%{1}}\ -Provides: kernel-devel = %{version}-%{release}%{?1:.%{1}}\ -Provides: kernel-devel-uname-r = %{KVERREL}%{?1:.%{1}}\ +Provides: kernel-devel-%{_target_cpu} = %{version}-%{release}%{?1:+%{1}}\ +Provides: kernel-devel = %{version}-%{release}%{?1:+%{1}}\ +Provides: kernel-devel-uname-r = %{KVERREL}%{?1:+%{1}}\ AutoReqProv: no\ Requires(pre): /usr/bin/find\ Requires: perl\ @@ -985,11 +985,11 @@ against the %{?2:%{2} }kernel package.\ Summary: Extra kernel modules to match the %{?2:%{2} }kernel\ Group: System Environment/Kernel\ Provides: kernel%{?1:-%{1}}-modules-extra-%{_target_cpu} = %{version}-%{release}\ -Provides: kernel-modules-extra-%{_target_cpu} = %{version}-%{release}%{?1:.%{1}}\ -Provides: kernel-modules-extra = %{version}-%{release}%{?1:.%{1}}\ +Provides: kernel-modules-extra-%{_target_cpu} = %{version}-%{release}%{?1:+%{1}}\ +Provides: kernel-modules-extra = %{version}-%{release}%{?1:+%{1}}\ Provides: installonlypkg(kernel-module)\ -Provides: kernel-modules-extra-uname-r = %{KVERREL}%{?1:.%{1}}\ -Requires: kernel-uname-r = %{KVERREL}%{?1:.%{1}}\ +Provides: kernel-modules-extra-uname-r = %{KVERREL}%{?1:+%{1}}\ +Requires: kernel-uname-r = %{KVERREL}%{?1:+%{1}}\ AutoReqProv: no\ %description -n kernel%{?variant}%{?1:-%{1}}-modules-extra\ This package provides less commonly used kernel modules for the %{?2:%{2} }kernel package.\ @@ -1578,7 +1578,7 @@ BuildKernel() { MakeTarget=$1 KernelImage=$2 Flavour=$3 - Flav=${Flavour:+.${Flavour}} + Flav=${Flavour:++${Flavour}} InstallName=${4:-vmlinuz} # Pick the right config file for the kernel we're building @@ -1898,13 +1898,13 @@ find Documentation -type d | xargs chmod u+w %define __modsign_install_post \ if [ "%{signmodules}" -eq "1" ];

18 Jun '13

Hello kernel list, as mentioned on the Frenoode IRC channel I would like to ask to have some backported (from 3.10) patches to be included in the Fedora 19 kernel. These patches are needed to fully complete the server side part of http://fedoraproject.org/wiki/Features/gss-proxy I am sorry coming late, but this work has been underway for very long (patches originally against 3.9.0) and I did not realize it wasn't going to end up in Fedora 19 kernel without proactive action until now. The patches are quite self-contained and tested. Bruce has kindly agree to backport them to 3.9.x (and we do not expect major difficulties there) and Jeff has agreed to review the backport. The list of upstream patches is the following: 030d794bf498 SUNRPC: Use gssproxy upcall for server RPCGSS authentication. 1d658336b05f SUNRPC: Add RPC based upcall mechanism for RPCGSS auth 400f26b542e8 SUNRPC: conditionally return endtime from import_sec_context 33d90ac0581c SUNRPC: allow disabling idle timeout 7073ea8799a8 SUNRPC: attempt AF_LOCAL connect on setup d28fcc830c2e svcrpc: fix gss-proxy to respect user namespaces 6278b62aa8f9 SUNRPC: gssp_procedures[] can be static 9fd40c5a66be SUNRPC: Refactor gssx_dec_option_array() to kill uninitialized warning fb43f11c666a SUNRPC: fix decoding of optional gss-proxy xdr fields 625cdd78d119 svcauth_gss: fix error code in use_gss_proxy() Please let me know if more information is needed, and what is the deadline, should you accept the proposal to have this included. Please keep me in CC as I am not subscribed to the list. Regards, Simo Sorce -- Simo Sorce * Red Hat, Inc * New York

[PATCH] kernel.spec: let flavors/variants end with "-$flavor" in the uname
by Harald Hoyer 12 Jun '13

12 Jun '13

From: Harald Hoyer <harald(a)redhat.com> This patch changes the version of kernel flavor/variants to end in "-$flavor" instead of ".$flavor". This makes it easier to detect a flavor and a parser can separate it from the architecture. With that change we can correct kernel-install (of systemd) to call new-kernel-package with --package kernel-$flavor, because the $flavor can easily be extracted from the version string. --- kernel.spec | 74 ++++++++++++++++++++++++++++++------------------------------- 1 file changed, 37 insertions(+), 37 deletions(-) diff --git a/kernel.spec b/kernel.spec index f85ba9a..9e17710 100644 --- a/kernel.spec +++ b/kernel.spec @@ -464,17 +464,17 @@ Summary: The Linux kernel # %define kernel_reqprovconf \ Provides: kernel = %{rpmversion}-%{pkg_release}\ -Provides: kernel-%{_target_cpu} = %{rpmversion}-%{pkg_release}%{?1:.%{1}}\ +Provides: kernel-%{_target_cpu} = %{rpmversion}-%{pkg_release}%{?1:-%{1}}\ Provides: kernel-drm = 4.3.0\ Provides: kernel-drm-nouveau = 16\ Provides: kernel-modeset = 1\ -Provides: kernel-uname-r = %{KVERREL}%{?1:.%{1}}\ +Provides: kernel-uname-r = %{KVERREL}%{?1:-%{1}}\ Provides: kernel-highbank\ -Provides: kernel-highbank-uname-r = %{KVERREL}%{?1:.%{1}}\ +Provides: kernel-highbank-uname-r = %{KVERREL}%{?1:-%{1}}\ Provides: kernel-omap\ -Provides: kernel-omap-uname-r = %{KVERREL}%{?1:.%{1}}\ +Provides: kernel-omap-uname-r = %{KVERREL}%{?1:-%{1}}\ Provides: kernel-tegra\ -Provides: kernel-tegra-uname-r = %{KVERREL}%{?1:.%{1}}\ +Provides: kernel-tegra-uname-r = %{KVERREL}%{?1:-%{1}}\ Requires(pre): %{kernel_prereq}\ Requires(pre): %{initrd_prereq}\ Requires(pre): linux-firmware >= 20120206-0.1.git06c8f81\ @@ -930,7 +930,7 @@ AutoReqProv: no\ %description -n %{name}%{?1:-%{1}}-debuginfo\ This package provides debug information for package %{name}%{?1:-%{1}}.\ This is required to use SystemTap with %{name}%{?1:-%{1}}-%{KVERREL}.\ -%{expand:%%global debuginfo_args %{?debuginfo_args} -p '/.*/%%{KVERREL}%{?1:\.%{1}}/.*|/.*%%{KVERREL}%{?1:\.%{1}}(\.debug)?' -o debuginfo%{?1}.list}\ +%{expand:%%global debuginfo_args %{?debuginfo_args} -p '/.*/%%{KVERREL}%{?1:\-%{1}}/.*|/.*%%{KVERREL}%{?1:\-%{1}}(\.debug)?' -o debuginfo%{?1}.list}\ %{nil} # @@ -942,9 +942,9 @@ This is required to use SystemTap with %{name}%{?1:-%{1}}-%{KVERREL}.\ Summary: Development package for building kernel modules to match the %{?2:%{2} }kernel\ Group: System Environment/Kernel\ Provides: kernel%{?1:-%{1}}-devel-%{_target_cpu} = %{version}-%{release}\ -Provides: kernel-devel-%{_target_cpu} = %{version}-%{release}%{?1:.%{1}}\ -Provides: kernel-devel = %{version}-%{release}%{?1:.%{1}}\ -Provides: kernel-devel-uname-r = %{KVERREL}%{?1:.%{1}}\ +Provides: kernel-devel-%{_target_cpu} = %{version}-%{release}%{?1:-%{1}}\ +Provides: kernel-devel = %{version}-%{release}%{?1:-%{1}}\ +Provides: kernel-devel-uname-r = %{KVERREL}%{?1:-%{1}}\ AutoReqProv: no\ Requires(pre): /usr/bin/find\ Requires: perl\ @@ -962,11 +962,11 @@ against the %{?2:%{2} }kernel package.\ Summary: Extra kernel modules to match the %{?2:%{2} }kernel\ Group: System Environment/Kernel\ Provides: kernel%{?1:-%{1}}-modules-extra-%{_target_cpu} = %{version}-%{release}\ -Provides: kernel-modules-extra-%{_target_cpu} = %{version}-%{release}%{?1:.%{1}}\ -Provides: kernel-modules-extra = %{version}-%{release}%{?1:.%{1}}\ +Provides: kernel-modules-extra-%{_target_cpu} = %{version}-%{release}%{?1:-%{1}}\ +Provides: kernel-modules-extra = %{version}-%{release}%{?1:-%{1}}\ Provides: installonlypkg(kernel-module)\ -Provides: kernel-modules-extra-uname-r = %{KVERREL}%{?1:.%{1}}\ -Requires: kernel-uname-r = %{KVERREL}%{?1:.%{1}}\ +Provides: kernel-modules-extra-uname-r = %{KVERREL}%{?1:-%{1}}\ +Requires: kernel-uname-r = %{KVERREL}%{?1:-%{1}}\ AutoReqProv: no\ %description -n kernel%{?variant}%{?1:-%{1}}-modules-extra\ This package provides less commonly used kernel modules for the %{?2:%{2} }kernel package.\ @@ -1544,7 +1544,7 @@ BuildKernel() { MakeTarget=$1 KernelImage=$2 Flavour=$3 - Flav=${Flavour:+.${Flavour}} + Flav=${Flavour:+-${Flavour}} InstallName=${4:-vmlinuz} # Pick the right config file for the kernel we're building @@ -1871,13 +1871,13 @@ find Documentation -type d | xargs chmod u+w %define __modsign_install_post \ if [ "%{signmodules}" -eq "1" ];

What is "TCP Application Buffer?"
by Maurizio Pagani 12 Jun '13

12 Jun '13

Hi Everybody, Someone, do you know what is in deep "TCP Application Buffer"? I'll want tuning my system but i'm reading on the web, that when i modify this parameter: . tcp_rmem . tcp_wmem in particular, this: tcp_app_win - INTEGER Reserve max(window/2^tcp_app_win, mss) of window for application buffer. Value 0 is special, it means that nothing is reserved. Default: 31 But unfortunatly, i don't know what is "application buffer". Someone can help me? Thanks a lot in advance. Maurizio

Patch for kernel variants/flavors
by Harald Hoyer 11 Jun '13

11 Jun '13

Here is a patch for the kernel.spec, which changes the version of kernel flavor/variants to end in "-$flavor" instead of ".$flavor". This change makes it easier to detect a flavor and a parser can separate it from the architecture. With that change we can correct kernel-install (of systemd) to call new-kernel-package with --package kernel-$flavor, because the $flavor can easily be extracted from the version string. Another solution would be to name the default kernel to have a flavor "default" like SUSE does, but this does not look nice. Another solution would be a hardcoded list of flavors in kernel-install. The last solution would be to add a flavor argument to kernel-install, which has no purpose other than to pass it through to new-kernel-package.
