Subject: [PATCH 4.19 stable v2 0/3] net: ip6 defrag: backport fixes
Date: Tue, 23 Apr 2019 10:25:30 -0700 [thread overview]
Message-ID: <20190423172533.245939-1-posk@google.com> (raw)
Lars Persson <lists@bofh.nu> reported that a label was unused in
the 4.14 version of this patchset, and the issue was present in
the 4.19 patchset as well, so I'm sending a v2 that fixes it.
The original 4.19 patchset queued for stable is OK, and
can be used as is, but this v2 is a bit better: it fixes the
unused label issue and handles overlapping fragments better.
Sorry for the mess/v2.
=======================
Currently, 4.19 and earlier stable kernels contain a security fix
that is not fully IPv6 standard compliant.
This patchset backports IPv6 defrag fixes from 5.1rc that restore
standard-compliance.
Original 5.1 patchet: https://patchwork.ozlabs.org/cover/1029418/
v2 changes: handle overlapping fragments the way it is done upstream
