Не просто OpenBMC: как мы сделали свой BMC
Привет, Хабр! Летом мы рассказывали о сложном, но очень интересном пути в создании UEFI-загрузчика для серверных продуктов компании OpenYard. Теперь хочется перейти к его постоянному спутнику ― BMC, без которого сегодня трудно представить полноценную серверную платформу.

Alrighty, I've merged the recipe bump to migrate the #OpenBMC kernel from v6.6 stable to v6.12 stable

@dexter well this is nice to see again, home sweet home in the Talos II bootloader - with a FreeBSD ISO installer ...
Left: OpenBMC interface w/ iKVM
Right: standard term via SSH to BMC and "obmc-console-client"14.2 is installing now, no surprises. tomorrow, more fun!

Next is "OpenBMC - The state of multi-host platform support" by Oliver Brewka
Multi-host in this context means having a single BMC managing multiple host nodes.
First multi-host system Yosemite appeared in 2015; the platform support was maintained in Meta-OpenBMC, and for the latest version it migrated to LF-OpenBMC.
One of the challenges was to go from a static to a dynamic design: the 1<->1 relation is broken, and the number of hosts might change (empty node slot). Changing the design in OpenBMC without breaking the many single-host platforms was the hard part.
As of lately, multi-host has been getting more attention in OpenBMC; Aspeed announced new multi-host capabilities for their next BMC SoC, for example.
Oliver says that multi-host in OpenBMC will improve the design, getting rid of much hard-coding, and getting closer the Redfish specification.

Tom takes over to talk about the firmware update side of the AMC with OpenBMC.
At NVIDIA, they have strong KPIs for firmware update performance and reliability, while still using standard, PLDM type 5 firmware update with Redfish.

Critical Vulnerability In OpenBMCs For Servers, Leads To Full Compromise https://cybersecuritynews.com/openbmcs-server-vulnerability/ #CyberSecurityNews #cybersecuritynews #NetworkSecurity #CyberSecurity #Vulnerability #cybersecurity #vulnerability #OpenBMC

Thanks to tremendous help from @zev & @arj I’ve managed to re-flash BMC. I almost succeeded with chain loaded openbmc to burn FW with amazing https://github.com/amboar/culvert, but accidentally fried UART on BMC. While I was looking for VGA→HDMI adapter in local groups to boot from USB pen drive, one person suggested to try to boot using PXE (mobo POSTed). And after some unpleasant time figuring out right set of pxe bootloaders it booted and I reflashed stock FW! #linux #bmc #openbmc #devops #hardware

Chipping away at some of the #OpenBMC kernel backlog ... linux-aspeed now integrates v6.6.16

The Open Source Firmware Foundation (https://osfw.foundation) invited to their fall community hackathon in #bochum.
It's #hackathon time: day 2.
Coffee machine is at the ready. Cold caffeinated beverages as well.
A lot of people brought #hardware to hack on. Yesterday people discussed not only technical details, but also strategies and politics to drive Open Source #Firmware forward on various popular architectures like x86, RISC-V and ARM for hosts and BMC. -

Konstantin did a write-up of getting PLDM going over the MCTP KCS binding (DSP0254) between EDK2 and #OpenBMC https://github.com/Kostr/PLDM
-
Asus just pushed a patch to #OpenBMC adding bitbake metadata for their X4TF platform
-
Looks like Akamai will be contributing to upstream #openbmc. Good to see the community continuing to expand
-
There's a sense of satisfaction moderating AMI posts through to the OpenBMC list. I feel like we've succeeded

#OpenBMC 2.14 Apparently Released

HPE is still making custom ASICs for its BMCs instead of buying off-the-shelf SoCs from Aspeed or Nuvoton.
So they had to do Linux enablement and upstreaming is ongoing.

Jean-Marie Verdun on bringing #OpenBMC in the HPE ProLiant server line.

Very nice first presentation by Erwan Velu on Open Source Firmware at the #OpenBMC meetup.
Withe the And launch of the hardware Operating Principles Manifesto. https://github.com/criteo/hardware-manifesto -
#EverythingOpen I see all these new #OpenBMC projects and then look at my homelab, which seems like it'll be stuck with ancient AST2400/AST2500 chips forever.

Interesting: an #OpenBMC meetup in Paris ! https://www.eventbrite.com/e/billets-rencontre-de-la-communaute-openbmc-parisienne-560881931957
I'll be there ! -
@kernellogger good to see HPE's GXP SoC support getting merged. Progress towards an upstream #OpenBMC port!
-
Discovered some interesting aspeed patches that Google keeps in their openbmc fork. The team there have made efforts to ensure all of their code is upstream, but it is a constant battle.
Perhaps a bot that scrapes Intel, Google, IBM and others who have public forks for out of tree patches would be interesting for discovering fixed that might be of benefit to the wider community.

A few weeks back I noticed the NCSI networking code in the kernel was hitting one of the new array length checks that the kernel now performs.
[ 44.642387] memcpy: detected field-spanning write (size 7) of
single field "&cmd->mfr_id" at net/ncsi/ncsi-cmd.c:231 (size 4)https://lore.kernel.org/netdev/CACPK8X[email protected]/
@kees looked at it for me and said that it was a case where we could tell the kernel to ignore the error.

Just reviewed a patch for an I2C driver by Nick from HPE. He's part of a team who are upstreaming kernel support for HPE's BMC ASIC so they can support OpenBMC on their hardware.
-
Just reviewed a patch set from Peter, a BMC developer at Facebook, who is improving support for emulating the various "FRU" EEPROMs attached to BMCs. They usually contain board-specific data programmed at manufacturing time, and the BMC userspace uses this data to configure itself.

#OpenBMC 2.12 Released For This #OpenSource, #Linux-Powered baseboard management controller (#BMC) Software Stack.
Lots of work to add OpenBMC support to various Meta (#Facebook) #motherboard and other #hyperscaler hardware

Pants down: #Sicherheitslücke in #Server-Fernwartung
Die #BMC-Chips #Aspeed #AST2400 und #AST2500 mit #OpenBMC-Firmware sowie mit Firmwares von #AMI und #Supermicro sind vom Hostprozessor aus angreifbar. Über PCI Express oder das Low-Pin-Count-(LPC-)Interface kann ein Angreifer den BMC komplett übernehmen.
Dadurch wiederum ließe sich die BMC-Firmware manipulieren, um Malware oder Spionagesoftware dauerhaft auf dem Server zu verankern.
