Revision 9cc20b268a5a14f5e57b8ad405a83513ab0d78dc authored by Eric Dumazet on 18 November 2011, 20:24:32 UTC, committed by David S. Miller on 18 November 2011, 20:24:32 UTC
commit f39925dbde77 (ipv4: Cache learned redirect information in inetpeer.) introduced a regression in ICMP redirect handling. It assumed ipv4_dst_check() would be called because all possible routes were attached to the inetpeer we modify in ip_rt_redirect(), but thats not true. commit 7cc9150ebe (route: fix ICMP redirect validation) tried to fix this but solution was not complete. (It fixed only one route) So we must lookup existing routes (including different TOS values) and call check_peer_redir() on them.

Mono(tm) Binary Kernel Support for Linux
-----------------------------------------
To configure Linux to automatically execute Mono-based .NET binaries
(in the form of .exe files) without the need to use the mono CLR
wrapper, you can use the BINFMT_MISC kernel support.
This will allow you to execute Mono-based .NET binaries just like any
other program after you have done the following:
1) You MUST FIRST install the Mono CLR support, either by downloading
a binary package, a source tarball or by installing from CVS. Binary
packages for several distributions can be found at:
http://go-mono.com/download.html
Instructions for compiling Mono can be found at:
http://www.go-mono.com/compiling.html
Once the Mono CLR support has been installed, just check that
/usr/bin/mono (which could be located elsewhere, for example
/usr/local/bin/mono) is working.
2) You have to compile BINFMT_MISC either as a module or into
the kernel (CONFIG_BINFMT_MISC) and set it up properly.
If you choose to compile it as a module, you will have
to insert it manually with modprobe/insmod, as kmod
cannot be easily supported with binfmt_misc.
Read the file 'binfmt_misc.txt' in this directory to know
more about the configuration process.
3) Add the following entries to /etc/rc.local or similar script
to be run at system startup:
# Insert BINFMT_MISC module into the kernel
if [ ! -e /proc/sys/fs/binfmt_misc/register ]; then
/sbin/modprobe binfmt_misc
# Some distributions, like Fedora Core, perform
# the following command automatically when the
# binfmt_misc module is loaded into the kernel.
# Thus, it is possible that the following line
# is not needed at all. Look at /etc/modprobe.conf
# to check whether this is applicable or not.
mount -t binfmt_misc none /proc/sys/fs/binfmt_misc
fi
# Register support for .NET CLR binaries
if [ -e /proc/sys/fs/binfmt_misc/register ]; then
# Replace /usr/bin/mono with the correct pathname to
# the Mono CLR runtime (usually /usr/local/bin/mono
# when compiling from sources or CVS).
echo ':CLR:M::MZ::/usr/bin/mono:' > /proc/sys/fs/binfmt_misc/register
else
echo "No binfmt_misc support"
exit 1
fi
4) Check that .exe binaries can be ran without the need of a
wrapper script, simply by launching the .exe file directly
from a command prompt, for example:
/usr/bin/xsd.exe
NOTE: If this fails with a permission denied error, check
that the .exe file has execute permissions.
