[net-next v3 0/4] seg6: add support for SRv6 Headend Reduced Encapsulation

by Andrea Mayer

This patchset adds support for SRv6 Headend behavior with Reduced Encapsulation. It introduces the H.Encaps.Red and H.L2Encaps.Red versions of the SRv6 H.Encaps and H.L2Encaps behaviors, according to RFC 8986 [1]. In details, the patchset is made of: - patch 1/4: add support for SRv6 H.Encaps.Red behavior; - Patch 2/4: add support for SRv6 H.L2Encaps.Red behavior; - patch 2/4: add selftest for SRv6 H.Encaps.Red behavior; - patch 3/4: add selftest for SRv6 H.L2Encaps.Red behavior. The corresponding iproute2 patch for supporting SRv6 H.Encaps.Red and H.L2Encaps.Red behaviors is provided in a separated patchset. [1] - https://datatracker.ietf.org/doc/html/rfc8986 v2 -> v3: - Keep SRH when HMAC TLV is present; - Split the support for H.Encaps.Red and H.L2Encaps.Red behaviors in two patches (respectively, patch 1/4 and patch 2/4); - Add selftests for SRv6 H.Encaps.Red and H.L2Encaps.Red. v1 -> v2: - Fixed sparse warnings; - memset now uses sizeof() instead of hardcoded value; - Removed EXPORT_SYMBOL_GPL. Andrea Mayer (4): seg6: add support for SRv6 H.Encaps.Red behavior seg6: add support for SRv6 H.L2Encaps.Red behavior selftests: seg6: add selftest for SRv6 H.Encaps.Red behavior selftests: seg6: add selftest for SRv6 H.L2Encaps.Red behavior include/uapi/linux/seg6_iptunnel.h | 2 + net/ipv6/seg6_iptunnel.c | 138 +++- .../net/srv6_hencap_red_l3vpn_test.sh | 742 ++++++++++++++++++ .../net/srv6_hl2encap_red_l2vpn_test.sh | 674 ++++++++++++++++ 4 files changed, 1554 insertions(+), 2 deletions(-) create mode 100755 tools/testing/selftests/net/srv6_hencap_red_l3vpn_test.sh create mode 100755 tools/testing/selftests/net/srv6_hl2encap_red_l2vpn_test.sh -- 2.20.1

[PATCH MANUALSEL 5.4] selftests: KVM: Handle compiler optimizations in ucall

by Sasha Levin

From: Raghavendra Rao Ananta <rananta(a)google.com> [ Upstream commit 9e2f6498efbbc880d7caa7935839e682b64fe5a6 ] The selftests, when built with newer versions of clang, is found to have over optimized guests' ucall() function, and eliminating the stores for uc.cmd (perhaps due to no immediate readers). This resulted in the userspace side always reading a value of '0', and causing multiple test failures. As a result, prevent the compiler from optimizing the stores in ucall() with WRITE_ONCE().

THIS IS VERY CONFIDENTIAL

by Steve Dibenedetto

Hello, My name is Steve Dibenedetto. I apologize to have contacted you this way without a direct relationship. There is an opportunity to collaborate with me in the sourcing of some materials needed by our company for production of the different medicines we are researching. I'm aware that this might be totally outside your professional specialization, but it will be a great source for generating extra revenue. I discovered a manufacturer who can supply us at a lower rate than our company's previous purchases. I will give you more specific details when/if I receive feedback from you showing interest. Warm Regards Steve Dibenedetto Production & Control Manager, Green Field Laboratories Gothic House, Barker Gate, Nottingham, NG1 1JU, United Kingdom.
