@june:mlp.chatJune [she/they] 🏳️‍⚧️♒ AFAIK, Pixel 6 and Pixel 6 Pro's processors should support Memory Tagging Extensions 06:58:02
@june:mlp.chatJune [she/they] 🏳️‍⚧️♒hardened_malloc will eventually implement it06:58:13

In reply to @graeme22:matrix.org
So do we have any info yet on the pixel 6 changes, namely the titan M2 and tensor chip? As in, what are the security improvements, if any? I'm assuming getting GOS on it will take a while.

@strcat:grapheneos.orgstrcat June [she/they] 🏳️‍⚧️♒: I don't think so 06:59:52
@strcat:grapheneos.orgstrcatthe next generation likely will06:59:56
@june:mlp.chatJune [she/they] 🏳️‍⚧️♒They don't?07:00:00
@june:mlp.chatJune [she/they] 🏳️‍⚧️♒ What does at this point? 07:00:05
@strcat:grapheneos.orgstrcatwell Apple skipped it since it's optional07:00:16
@strcat:grapheneos.orgstrcatApple calls their chips ARMv8.4 or w/e but skipped all the interesting stuff07:00:27
@strcat:grapheneos.orgstrcatthe ARM standard cores are ARMv8.2 with backported ARMv8.4 features07:00:43
@strcat:grapheneos.orgstrcatI can't really tell you why that is07:00:46
@june:mlp.chatJune [she/they] 🏳️‍⚧️♒Interesting07:00:56
@strcat:grapheneos.orgstrcatit will seemingly not have memory tagging until they move to X2 next year07:01:24
@strcat:grapheneos.orgstrcatI think that's just how it is07:01:26
@strcat:grapheneos.orgstrcatdon't know for sure07:01:31
@strcat:grapheneos.orgstrcatthey could have added tagging as a backported extension07:01:38
@strcat:grapheneos.orgstrcatI doubt it though07:01:40

I'm disappointed to recently learn that GrapheneOS won't support yubikeys when it implements FIDO support
the yubikey will no longer work? that's a problem
07:03:14
@strcat:grapheneos.orgstrcatno07:04:36
@strcat:grapheneos.orgstrcatour own FIDO2 library will use the secure element in the phone07:04:58
@strcat:grapheneos.orgstrcatno impact on other FIDO2 implementations07:05:05
@strcat:grapheneos.orgstrcator other uses of YubiKeys/whatever07:05:11
@strcat:grapheneos.orgstrcatwe only support phones with a secure element already in them07:05:41
@strcat:grapheneos.orgstrcatwe don't need to bother with USB, Bluetooth, NFC, etc. to use a secure element07:05:53
@thatcher:matrix.orgthatcherHell yeah!!!07:06:07
@strcat:grapheneos.orgstrcatwe want to make something different and better07:06:55
@strcat:grapheneos.orgstrcatinstead of making another take on the same thing07:07:03
@anupritaisno1:grapheneos.orgrandomhydrosolIronically more secure than some secure elements already07:07:20
@strcat:grapheneos.orgstrcatmore secure than nearly all of them in all likelihood07:07:31
@anupritaisno1:grapheneos.orgrandomhydrosolTitan M has updatable firmware to fix issues in the first place07:07:43
