Branches merging from 'feature-ipc' to 'master' is happening

by Ken Liu (Arm Technology China)

Hi TF-M Subscribers, The branch 'feature-ipc' is going to be merged into 'master', and here is the patch: https://review.trustedfirmware.org/c/trusted-firmware-m/+/677 After the merging, the IPC feature will be available in the 'master' branch, future updates on the IPC part will happen in 'master' branch, too. For those patches pushed towards 'feature-ipc' will be reviewed and we suggest push new patchset to 'master' branch. Please reply to this thread without hesitation if there are any questions. Thanks. -Ken

Re: [TF-M] Trusted boot - rollback protection

by David Brown

On Mon, Mar 11, 2019 at 01:43:19PM +0000, Tamas Ban via TF-M wrote: >https://developer.trustedfirmware.org/w/tf_m/design/trusted_boot/rollback_p… Oh, and a little terminology comment about the Trusted non-volatile (NV) counters. This section should use "increase" and "decrease" not "increment" and "decrement". There is no requirement that the counter only be incremented (having 1 added to the value), only that it be set to a larger value than the current value. You should probably also add a discussion as to how testing will be done with a HW security counter. Again, my suggestion is to not add an additional counter, but just use the existing version field (minus the build number) as the security counter value. David

Re: [TF-M] multiple services within the same SP

by Andrew Thoelke

Hi Alan, I can answer this from the PSA Firmware Framework specification point of view, Ken (or others in the TF-M team) can clarify how closely the TF-M behaviour matches this. In the manifest each service has a "signal" attribute which is a C identifier that is given the signal value for that service. The value is allocated by the TF-M tools and should be available to the SP source code via a generated header file - the specification places these definitions in the psa_manifest/<manifestfilename>.h header file, matching the name of the manifest file itself. When the SP receives a set of signals from psa_wait(), it can identify which signals are asserted using these identifiers to test the signal bits. The example RoT Service in Appendix D of the PSA Firmware Framework demonstrates this.

Re: [TF-M] multiple services within the same SP

by Ken Liu (Arm Technology China)

Hi Alan, Services are listed in SP. SPM could enumerate the services in a SP by the list. You can check the member variable ' service_list' of ' tfm_spm_ipc_partition_t' to know details. -Ken > -----Original Message----- > From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of DeMars, > Alan via TF-M > Sent: Friday, March 8, 2019 9:52 PM > To: tf-m(a)lists.trustedfirmware.org > Subject: [TF-M] multiple services within the same SP > > In a multi-service SP, how does the SP know which SID has been used to connect > to it? > -- > TF-M mailing list > TF-M(a)lists.trustedfirmware.org > https://lists.trustedfirmware.org/mailman/listinfo/tf-m IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.

multiple services within the same SP

by DeMars, Alan

In a multi-service SP, how does the SP know which SID has been used to connect to it?

Re: [TF-M] META: TF-M Mailing list configuration
