[Bug 2051876] Re: tpm2_nvwrite using an offset causes a TPM error
Hello again, Sudip, hope this message finds you well! I attempted to recreate the issue using a cert whose footprint exceeds the 1,024 byte TPM data bus by using two tpm2_nvwrite commands (the second of which specifying --offset=1024) and I'm happy to report that it's working! However, we were experiencing the issue on HP gear and this is a Dell laptop.. so I still need to test it on HP. thanks again! -andy -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2051876 Title: tpm2_nvwrite using an offset causes a TPM error To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/tpm2-tools/+bug/2051876/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 2051876] Re: tpm2_nvwrite using an offset causes a TPM error
Thanks for looking into this, Sudip! I will need to write up explicit instructions, but the issue only shows up when you attempt to write to an offset, which (I would presume) is why your test didn't produce any issues. My usecase is storing a DER encoded x509 certificate whose footprint exceeds the TPM data bus size, thus requiring multiple tpm2_nvwrite calls, with any call other than the initial, requiring the --offset flag and the appropriate offset starting point. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2051876 Title: tpm2_nvwrite using an offset causes a TPM error To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/tpm2-tools/+bug/2051876/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 2051876] Re: tpm2_nvwrite using an offset causes a TPM error
Thanks for reporting the bug. I tried to reproduce the issue on Jammy but could not reproduce it. The following is from my session: # tpm2_nvdefine -C o -s 32 -a "ownerread|policywrite|ownerwrite" 1 nv-index: 0x101 # echo "please123abc" > nv.dat # tpm2_nvwrite -C o -i nv.dat 1 # tpm2_nvread -C o -s 32 1 please123abc # apt-cache policy tpm2-tools tpm2-tools: Installed: 5.2-1build1 Candidate: 5.2-1build1 Version table: *** 5.2-1build1 500 500 http://archive.ubuntu.com/ubuntu jammy/universe amd64 Packages 100 /var/lib/dpkg/status It will really help us if can please give the steps that you followed to reproduce the issue. I am marking the bug as Incomplete till then, please change the status back to New when you add the steps. ** Changed in: tpm2-tools (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2051876 Title: tpm2_nvwrite using an offset causes a TPM error To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/tpm2-tools/+bug/2051876/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
