The instruction sequence used is minimal to reduce overhead. Crucially, a stackframe is not created for the function being traced. This breaks stack unwinding since the function being traced does not have a stackframe for itself.

[PATCH 5.15.x] RDMA/irdma: Prevent zero-length STAG registration

by Shiraz Saleem

From: Christopher Bednarz <christopher.n.bednarz(a)intel.com> [Upstream commit bb6d73d9add68ad270888db327514384dfa44958] Currently irdma allows zero-length STAGs to be programmed in HW during the kernel mode fast register flow. Zero-length MR or STAG registration disable HW memory length checks. Improve gaps in bounds checking in irdma by preventing zero-length STAG or MR registrations except if the IB_PD_UNSAFE_GLOBAL_RKEY is set. This addresses the disclosure CVE-2023-25775. The kernel version to apply this patch is 5.15.x.

Apply b8ec60e1186cdcfce41e7db4c827cb107e459002 to linux-6.6.y

by Nathan Chancellor

Hi Greg and Sasha, Please consider applying commit b8ec60e1186c ("x86/speculation, objtool: Use absolute relocations for annotations") to linux-6.6.y, which is the only supported stable version that has the prerequisite commit 1c0c1faf5692 ("objtool: Use relative pointers for annotations"). This fixes a bunch of warnings along the lines of the one in the commit message that are seen when linking ARCH=i386 kernels with ld.lld 18+. It picks cleanly for me. Cheers, Nathan

[PATCH] ksmbd: Mark as BROKEN in the 5.15.y kernel

by Greg Kroah-Hartman

Due to many known bugfixes not being backported properly to the 5.15.y kernel tree, the ksmbd code in this branch is just not safe to be used at this point in time at all. So mark it as BROKEN so it will not be used. This can be changed in the future if all needed backports are made by anyone who cares about this code in this stable kernel branch.
