Have you had this? It is for your Benefit

by Private Mail

Our Ref: BG/WA0151/2022 Dear Beneficiary Subject: An Estate of US$15.8 Million Blount and Griffin Genealogical Investigators specializes in probate research to locate missing heirs and beneficiaries to estates in the United Kingdom and Europe. We can also help you find wills, obtain copies of certificates, help you to administer an estate, as well as calculating how an estate, intestacy or trust should be distributed. You may be entitled to a large pay out for an inheritance in Europe worth US$15.8 million. We have discovered an estate belonging to the late Depositor has remained unclaimed since he died in 2011 and we have strong reasons to believe you are the closest living relative to the deceased we can find. You may unknowingly be the heir of this person who died without leaving a will (intestate). We will conduct a probate research to prove your entitlement, and can submit a claim on your behalf all at no risk to yourselves. Our service fee of 10% will be paid to us after you have received the estate. The estate transfer process should take just a matter of days as we have the mechanism and expertise to get this done very quickly. This message may come to you as a shock, however we hope to work with you to transfer the estate to you as quickly as possible. Feel free to email our senior case worker Mr. Malcolm Casey on email: malcolmcasey68(a)yahoo.com for further discussions. With warm regards, Mr. Blount W. Gort, CEO. Blount and Griffin Associates Inc

using mbuto to run kselftests

by Stefano Brivio

Hi, Thanks to a substantial contribution by Sevinj Aghayeva during the Outreachy contribution phase, mbuto (a shell script building initramfs images that can be loaded by qemu) can now be used to conveniently run kernel selftests in VMs. The website at: https://mbuto.sh/ shows examples with kselftests and a link to the man page. Comments, bug reports and patches are all very welcome! -- Stefano

I would expect them to work, they seemed happy when I was doing the async mode support IIRC and a quick spin with -next in qemu everything seems fine, I'm travelling so don't have the environment for models to hand right now. > [1] Command line: > "$MODEL" \ > -C cache_state_modelled=0 \ > -C bp.refcounter.non_arch_start_at_default=1 \ > -C bp.secure_memory=false \ > -C cluster0.has_arm_v8-1=1 \ > -C cluster0.has_arm_v8-2=1 \ > -C cluster0.has_arm_v8-3=1 \ > -C cluster0.has_arm_v8-4=1 \ > -C cluster0.has_arm_v8-5=1 \ > -C cluster0.has_amu=1 \ > -C cluster0.NUM_CORES=4 \ > -C cluster0.memory_tagging_support_level=2 \ > -a "cluster0.*=$AXF" \ > where $AXF contains a kernel at v5.18-rc5-16-g107c948d1d3e[2] and an > initrd built by mbuto[3] from that level with a slightly tweaked "kselftests" > profile (adding /dev/shm). What are you using for EL3 with the model? Both TF-A and boot-wrapper are in regular use, TF-A gets *way* more testing than boot-wrapper which is mostly used by individual developers.

[PATCH v2 0/5] binder: extended error and logging enhancements

This is a followup from [1], in which a split of commits was suggested by Greg. Additionally, the following changes were removed and not included in this v2 version: - dropped the binder_transaction_log_entry->strerr[] logic - dropped the binder_transaction_error() do-it-all function - dropped the re-work of current binder_user_error() messages [1] https://lore.kernel.org/r/20220421042040.759068-1-cmllamas@google.com/ Carlos Llamas (5): binder: add failed transaction logging info binder: add BINDER_GET_EXTENDED_ERROR ioctl binderfs: add extended_error feature entry binder: convert logging macros into functions binder: additional transaction error logs drivers/android/binder.c | 153 ++++++++++++++++-- drivers/android/binder_internal.h | 3 + drivers/android/binderfs.c | 8 + include/uapi/linux/android/binder.h | 16 ++ .../filesystems/binderfs/binderfs_test.c | 1 + 5 files changed, 165 insertions(+), 16 deletions(-) base-commit: 8013d1d3d2e33236dee13a133fba49ad55045e79 -- 2.36.0.464.gb9c8b46e94-goog

[PATCH v6 1/2] net: fix wrong network header length

by Lina Wang

When clatd starts with ebpf offloaing, and NETIF_F_GRO_FRAGLIST is enable, several skbs are gathered in skb_shinfo(skb)->frag_list. The first skb's ipv6 header will be changed to ipv4 after bpf_skb_proto_6_to_4, network_header\transport_header\mac_header have been updated as ipv4 acts, but other skbs in frag_list didnot update anything, just ipv6 packets. udp_queue_rcv_skb will call skb_segment_list to traverse other skbs in frag_list and make sure right udp payload is delivered to user space. Unfortunately, other skbs in frag_list who are still ipv6 packets are updated like the first skb and will have wrong transport header length. e.g.before bpf_skb_proto_6_to_4,the first skb and other skbs in frag_list has the same network_header(24)& transport_header(64), after bpf_skb_proto_6_to_4, ipv6 protocol has been changed to ipv4, the first skb's network_header is 44,transport_header is 64, other skbs in frag_list didnot change.After skb_segment_list, the other skbs in frag_list has different network_header(24) and transport_header(44), so there will be 20 bytes different from original,that is difference between ipv6 header and ipv4 header. Just change transport_header to be the same with original. Actually, there are two solutions to fix it, one is traversing all skbs and changing every skb header in bpf_skb_proto_6_to_4, the other is modifying frag_list skb's header in skb_segment_list. Considering efficiency, adopt the second one--- when the first skb and other skbs in frag_list has different network_header length, restore them to make sure right udp payload is delivered to user space.
