- Report all suspected Security issues to security@samba.org to allow us to follow our Security Process.
- Read the instructions: https://www.samba.org/~asn/reporting_samba_bugs.txt
- Report the problem in the Samba bug tracking system: https://bugzilla.samba.org/
- Always include the Samba version number in your bug reports!
Before you report a bug, verify that you are running a maintained version of Samba and update, if necessary. |

If you run into problems with the SMB client in the Linux kernel (cifs.ko, mount.cifs) don't hesitate to report it.
Similarly, please report all security issues or defects in the kernel client or its userspace tools (cifs-utils, mount.cifs, ...) to security@samba.org and never on IRC, public mailing lists or in Bugzilla. |
For the kernel client things are a bit more complex. There are 2 bug tracking systems which you should look at to see if your problem has already been reported:
You can also ask questions on the linux-cifs mailing-list (linux-cifs@vger.kernel.org ) (web archive here).
If you report a bug, a network capture and a kernel console log output is always helpful.
# make the kernel as verbose as possible echo 'module cifs +p' > /sys/kernel/debug/dynamic_debug/control echo 'file fs/cifs/* +p' > /sys/kernel/debug/dynamic_debug/control echo 1 > /proc/fs/cifs/cifsFYI echo 1 > /sys/module/dns_resolver/parameters/debug # get kernel output + network trace dmesg --clear tcpdump -s 0 -w trace.pcap & pid=$! sleep 3 mount.cifs ....cd ... ls.. etc.. (the thing that fails) sleep 3 kill $pid dmesg > trace.log
This should produce a trace.pcap and a trace.log file.
Be sure to mention your kernel version, server software and version.
