Hi everybody ! I am encountering performance problem on my bridgehead DC. I have 19 DC (Debian Stretch / Samba 4.6.7 from Tranquil.it repo) and they all synchronized on a main bridgehead DC. This performance problem first appears when the bridgehead DC was on Debian Jessie and kernel was updated with meltdown/spectre patch from Debian (3.16.51-3+deb8u1) I added "nopti" option to grub

Jessie also has the problem, even before the meltdown patches. The kernel 3.16.x had ksoftirqd probems, eating up cpu cicles. Make sure you use kernel 4.9.0-6 And i suggest move up to samba 4.7.x or 4.7.4 from debian/buster, Or use my 4.6.12/4.7.6 packages for stretch, or ask if Tranquil.it can make them. The 4.6.14 is still in the make atm for stretch, 4.6.14 for jessie is done. And last,

Unprivileged user can crash kernel by using DRM_IOCTL_NOUVEAU_CHANNEL_ALLOC ioctl. This was reported by trinity[1] fuzzer.

Hi Louis, Move up to 4.7 is planned soon but I'm little scared to update bridgehead if it actually had performance problem. I would like to fix all problem before updating. My smb.conf is really simple: [global] workgroup = PR realm = pr.educationetformation.fr netbios name = DC000 server role = active directory domain controller bind interfaces only

hey, I'm seeing an Oops when nouveau loads (see below). I've verified that this is because both device->chip and device->name are NULL prior to the strncpy()s at the end of nvkm_udevice_info(). Bisect shows that this started happening after: commit 24d5ff40a732633dceab68c6559ba723784f4a68 Author: Karol Herbst <kherbst at redhat.com> Date: Tue Apr 28 18:54:02 2020 +0200

...wordless logins for menus and interfaces, and take out the unlikely exploitation vector of the PTY (along with saving resources and potential complications). Of course, this can be used in other scenarios as well. I wrote a patch and submitted it to the mailing list. I originally called the option NoPty, but was advised by Iain Morgan to change it to PermitTTY. I've done so, and have tested it. It works perfectly in my own testing, though it has not been tested in any other environments as far as I know. The changes are pretty simple, and I've also touched the man pages. I was unable to fi...
