Palimerlin1991: why are calendar-backend, cityinfo, mce, osso-product-info, pulseaudio-policy-enforcement and telepathy-gabble not included in CSSU-T?09:43
Palitelepathy-gabble fix video calls with gmail web plugin, pulseaudio-policy-enforcement just disable useless logs in syslos and calendar-backend fix bug 1268209:45
povbot_Bug https://bugs.maemo.org/12682 calendar-backend's ICalConverter class does not export proper iCal data09:45

freemangordonPali: didn't you receive merlin1991's mail where he asked us to check if anything is missing?11:35
Palido not see it :-(11:35
Palisubject/message-id?11:35
freemangordonjust a second11:35
freemangordonsubject: "CSSU T10 packages"11:36
freemangordonPali: also, what am y supposed to look for in nishanth's log?11:37
freemangordons/y/I11:37
Palifreemangordon: do you have account on that TI forum?11:38
freemangordonIIRC yes11:38
freemangordonforum?11:38
Sicelofreemangordon: quick question -- i was on thumb, then updated to the latest CSSU-T .. now there are no thumb packages on my system .. is this expected?11:39
freemangordonSicelo: no11:39
freemangordonPali: e2e.ti.com is not a forum afaik11:39
Palifreemangordon: e2e.ti.com or whatever it is11:39
Palican you ask question how to check at runtime if L3 firewall is enabled for omap sha/aes/md5 crypto driver?11:40
freemangordonI guess I can :)11:41
freemangordonwill do, after having a lunch as I am starving11:41
Siceloi guess i must reinstall thumb again .. otherwise i didn't have any bad effects from this 'downgrade'11:42
Siceloor is there another way to check if i'm still on thumb?11:42
Paliok, here is kernel panic log which is generated when L3 firewall is not enabled on HS device and omap-aes.ko is loaded: http://thread.gmane.org/gmane.linux.ports.arm.omap/108397/11:42
PaliSicelo: check if is deb package has *thumb* in version string11:42
Palithats all... if package has thumb substring in version, then it is thumb compiled, otherwise not11:43
freemangordonPali: BTW can't you ask on #armlinux?12:00
Paliwe already asked on linux arm and omap ML ...12:01
freemangordonSicelo: do as Pali said, it makes no sense -testing to overwrite -thumb, unless you have very old version12:01
freemangordonPali: ok12:01
freemangordonneed to figure out how to ask questions on e2e12:01
freemangordonhmm, only omap4 and omap5 forums12:04
freemangordon:(12:04
Sicelowell, it did, curious12:06

freemangordonPali: http://e2e.ti.com/support/dsp/omap_applications_processors/f/447/t/39146712:12
Palifreemangordon: thanks!12:13
sixwheeledbeastSicelo: you definitely have no thumb packages at all?12:23
Siceloi know .. that's why i was asking if the update should have done this. i *did* have thumb before updating to cssu-t. of course it's too late now, haha .. will just reinstall thumb  sometime soon12:35
bencohwhat do you mean by "updating to cssu-t" ?12:37

freemangordonPali: for that aes to function, what was needed - new NOLO or new xloader?13:25
Paliboth13:25
freemangordonhmm, doesn't make sense13:25
Paliand even new flasher.rover binary :D13:25
freemangordonI know those are packaged together, but is everything different?13:26
Paliyes, both nolo and xloader are different13:26
PaliI can send binaries via emails13:26
freemangordonI have them13:27
freemangordonRX-51_2009SE_crypto.tar.gz ?13:27
freemangordonPali: did you try to flash only xloader or only nolo?13:28
PaliI have n900-crypto.tar.gz, omap-hw.tar.gz, nolo.tar.gz, omap-sha1-md5-standalone.diff, omap-aes-standalone.diff13:29
PaliI did not tried to flash that images yet13:29
freemangordonPali: my idea is - find how is that FW enabled and where (nolo or xloader), then find a way to do it from the kernel itself13:30
Palibut I will try on testing N900 from Doc in January13:30
freemangordonI bet there is some SMC that can be (ab)used13:30
Palitmlind suggested to dump some omap regs on normal xloader and that patched xloader if they are different13:30
freemangordonBTW ARM hexrays works on both nolo and xloader13:30
freemangordonPali: yep, makes sense13:31
Palimaybe it can be used for that runtime detection13:31
PaliI was told that new patched xloader (or NOLO??) has linked some binary blob from TI which doing something13:31
Palineeded for omap aes13:31
freemangordonhmm13:32
PaliI think it will be just example blob which enable L3 firewall13:32
freemangordonenable?13:32
freemangordonor rather disable13:32
Palienable access13:33
Paliin public TRM is written something about configuring L3 firewall for GP devices13:33
freemangordonwhich TRM, 35xx?13:34
PaliOMAP34xx_ES3.1.x_PUBLIC_TRM_vZT.pdf13:35
freemangordonI have ZM here, shouldnt be that much different13:35
Pali5.2 L3 Interconnect13:36
freemangordonyeah, I am reading through it13:37
freemangordonnot that I understand what is written there :D13:38
Pali5.2.5.4.1 Protection Mechanism (PM) Register Description13:39
Palithere is L3_PM_REQ_INFO_PERMISSION_i and L3_PM_READ_PERMISSION_i13:39
Paliand L3_PM_ADDR_MATCH_k13:40
PaliI think some of those registers we should use13:40
Palibut I do not understand that documents too :-(13:41
freemangordonhmm, xloader and nolo are SMALLER in RX-51_2009SE_crypto.tar.gz than in PR1.3 fiasko13:47
*** dhbiker has quit IRC13:56
Palifreemangordon: can you tell me sha1sum of RX-51_2009SE_crypto.tar.gz?13:59
PaliI have: cf6eac7aed41b5161d50c0361378f6bd1cc06d28  n900-crypto.tar.gz14:00
*** dhbiker has joined #maemo-ssu14:09
freemangordonPali: same here14:16
*** _rd has quit IRC14:31
freemangordonPali: hmm, I can;t see anything different in xloader, besides date string and some other trivial stuff14:32
freemangordonso it must be in nolo14:32
Palireally? xloader is same?14:37
Palifreemangordon: then we should be able to enable aes from kernel...14:38
PaliI still do not know why was needed new flasher binary for flashing...14:39
PaliI think it is doing same calls14:39
Paliit just extend Mk II flashing protocol which is used in PC-Suite and Update mode14:39
Palibut I did not see anything new in normal flashing14:40
freemangordonPali: I guess dmitry just packaged it all together, for consistency14:44
freemangordonit was dmitry, correct?14:44
Paliyes14:45
Pali"In order to use AES hw it is necessary to enable it during boot from Secure side."14:45
Pali"It is done by special code which is compiled as part of bootloader."14:45
Pali"You need special boot loader, because it has secure code to enable it.."14:46
Pali"You cannot do it from non-secure side."14:46
Pali"Nolo has binary blob for that."14:46
freemangordonsee, it is nolo14:46
Palifrom Dmitry Kasatkin14:46
*** _rd has joined #maemo-ssu14:47
PaliI think that with NOLO he means both xloader+secondary images14:47
Palibut do not know now...14:47
freemangordonmaybe there is modified PPA in NOLO which enables it14:47
* freemangordon checks NOLO14:48
Paliis NOLO running as secure or non secure?14:48
freemangordonnon-secure AFAIK14:48
freemangordonbut PPA runs in secure mode14:48
freemangordonand afaik PPA is loaded by SMC call14:48
Palithen only x-loader can set own PPA call14:49
freemangordonhmm, no, nolo can do it as well14:49
freemangordonit just needs to issue the correct SMC14:49
Palithen you should do it also from kernel14:49
freemangordonnot sure we can do it, as PPA is signed14:50
freemangordonbut yes, I guess we can load PPA from kernel14:50
Palihttp://www.droid-developers.org/wiki/Category:Security14:50
freemangordonif we have the blob and the signature14:50
Palihttp://www.droid-developers.org/wiki/Secure_Services14:50
Palilooks like some services are SW14:51
freemangordonSW?14:52
Paliloaded by SW14:52
freemangordonyep, my point exactly14:52
freemangordonyou can load PA by issuing a SMC call14:53
Palithen it looks like NOLO loads its own service for HW rng and allow kernel to use it via SMC14:53
freemangordonso, maybe it is possible to strip that blob (and signature) from NOLO and load it from kernel14:53
freemangordon:nod:14:53
Palipossible14:54
freemangordonhmm, NOLO is completely different, from the start14:56
freemangordonPali: do you remember at which address is NOLO loaded?14:59
Palimaybe 0x8040000015:01
freemangordonthanks15:01
Paliit is what I have in unfinished spl port of uboot15:02
Pali~ping15:05
infobot~pong15:05
*** M4rtinK has joined #maemo-ssu15:06
Paliyes, in uboot is comment that Nokia X-Loader loads secondary image to address 0x8040000015:07

merlin1991Pali: I'll prepare a T10.1 in jan that will include the missing bits16:14
Paliok16:15
merlin1991I'd do it this week, but starting with the 27th I'll be gone untill the 1st, don't want to risk it that I botch something and the repo is foobar for so long16:18
*** _rd has quit IRC16:34
freemangordonPali: oh, modified nolo seems to set IBE bit in aux CR :)16:45
*** sparetire_ has joined #maemo-ssu17:08
freemangordonPali: dammit, I can't find significant differences in NOLO either, besides this IBE bit in ACR, but it should be unrelated :(17:47
