No need to update ps3tools readself & readself2, it is still 0016 for 3.73 (same as 3.70/3.72) which afaik also means no new keys where added...Code:release:03.7300: build:52870,20111004:tetsu@tetsu-linux20 target:0001:CEX-ww security:4605@security/sdk_branches/release_373/trunk: system:48231[MENTION=199279]SyS[/MENTION]/sdk_branches/release_373/trunk: x3:15897@x3/branches/target37x: paf:6161@paf/branches/target37x: vsh:87088@vsh/branches/target37x: sys_jp:78[MENTION=199279]SyS[/MENTION]_jp/branches/target37x: ps1emu:7628@emu/branches/target101/ps1: ps1netemu:7630@emu/branches/target370/ps1_net: ps1newemu:6705@emu/branches/target202/ps1_new: ps2emu:6766@emu/branches/target360/ps2: ps2gxemu:14788[MENTION=69462]bran[/MENTION]ches/target360/gx: ps2softemu:15529[MENTION=69462]bran[/MENTION]ches/soft190/soft: pspemu:7830@emu/branches/target373/psp: emerald:3829[MENTION=109881]eme[/MENTION]rald/target37x: bdp:16885@bdp/prof5/branches/target37x: patch:: auth:52870:From Sony PlayStation 3 hacker Mathieulh via IRC on signing PS3 executables for 3.73+ Firmware:Code:struct id2name_tbl t_sdk_type[] = { {0, "Retail (Type 0)"}, {1, "Retail"}, {2, "Retail (Type 1)"}, {3, "Unknown SDK3"}, {4, "Retail >=3.40"}, {5, "Unknown SDK5"}, {6, "Unknown SDK6"}, {7, "Retail >=3.50"}, {8, "Unknown SDK8"}, {9, "Unknown SDK9"}, {10, "Retail >=3.55"}, {11, "Unknown SDK11"}, {12, "Unknown SDK12"}, {13, "Retail >=3.56"}, {14, "Unknown SDK14"}, {15, "Unknown SDK15"}, {16, "Retail >=3.60"}, {17, "Unknown SDK17"}, {18, "Unknown SDK18"}, {19, "Retail >=3.65"}, {20, "Unknown SDK20"}, {21, "Unknown SDK21"}, {22, "Retail >=3.70"}, {23, "Unknown SDK23"}, {24, "Unknown SDK24"}, {0x8000, "Devkit"}, {0, NULL} };As always, more details will be posted below as they are available on the update should any hidden features surface.Code:[21:00:58] <Mathieulh> selfs are a mess to generate properly because a lot of values need to be calculated from the original elf file [21:01:11] <Mathieulh> the problem is right now all the public tools use hardcoded values [21:01:19] <Mathieulh> that are grabbed from various self files [21:01:21] <Mathieulh> but are not calculated [21:01:34] <Mathieulh> well that's one of the many problems actually [21:01:35] <jevin> Mathieulh, things other than elf offsets? [21:01:40] <Mathieulh> yah [21:02:03] <Mathieulh> sony also did some fancy things with the compression self format [21:02:12] <Mathieulh> where values are off by a certain offset etc etc [21:02:38] <Mathieulh> if you want to make a proper self tool [21:02:44] <Mathieulh> you first need to reverse make_fself [21:03:06] <jevin> not too hard with hexrays *cough* [21:03:09] <Mathieulh> that's the initial step [21:03:15] <Mathieulh> yeah it's not that hard [21:03:29] <Mathieulh> then you'll figure what a big fck up the self format really is :D [21:05:14] <Mathieulh> but yeah just my self.cpp is 5 times larger than the entire source for geohot make_self/make_self_npdrm [21:05:27] <Mathieulh> in terms of lines of code [21:05:48] <Mathieulh> so his is missing shitloads of stuffs and only relies on hardcoded values [21:06:06] <jevin> entire headers copypasta'ed from existing selfs [21:06:11] <Mathieulh> pretty much yah :D [21:06:23] <Mathieulh> the ones on the tool I use are generated [21:06:32] <Mathieulh> as in calculated and generated [21:06:36] <Mathieulh> from the original elf [21:06:52] <Mathieulh> btw unself is buggy too [21:06:54] <Mathieulh> just so you know [21:07:16] <jevin> why haven't you labeled the control flags? :) [21:08:16] <Mathieulh> jevin I didn't feel the need to, I already know what they do anyway [21:08:37] <Mathieulh> for example 0x40 is root rights, 0x20 is debugger rights and so on [21:09:07] <jevin> i'm guessing the self capabilities flags are offset 0x20 in the self header [21:09:18] <Mathieulh> capabilities aren't in the header [21:09:23] <Mathieulh> they are part of the metadata [21:09:28] <Mathieulh> as in, they are encrypted and signed [21:10:16] <jevin> offset 0x10 in the section header? [21:10:29] <Mathieulh> it's after the metadata keys [21:10:33] <jevin> no, they wouldn't be per section [21:10:50] <Mathieulh> as in, right after them [21:11:09] <jevin> i see. so unself doesn't have enough fields in the metadata header [21:11:35] <jevin> i really should color in the hex values that are mapped to structures in unself vs ones that arent [21:11:42] <jevin> seems like it is missing a lot [21:11:49] <Mathieulh> everything public is missing tons [21:12:15] <Mathieulh> capabilities are optional mind you [21:12:35] <jevin> are they restrictive or permissive? [21:13:11] <Mathieulh> restrictive [21:13:16] <Mathieulh> (for most) [21:42:15] <jevin> Mathieulh, you said that the geohot npdrm keypair is blacklisted in 3.56 [21:42:30] <jevin> i couldnt find the decrypted or encrypted metadata keypair in 3.56 files [21:42:47] <jevin> where does the blacklisting occur? is it a hash that is blacklisted? [21:43:08] <jevin> its interesting to me because we can make our own keypairs now with juan nadie's work [21:48:45] <Mathieulh> <jevin> Mathieulh, you said that the geohot npdrm keypair is blacklisted in 3.56 <== not only that [21:49:03] <Mathieulh> geohot stuff doesn't generate some of the npdrm specific values [21:49:08] <Mathieulh> those were not checked in 3.55 [21:49:13] <Mathieulh> but they are checked in 3.56 now [21:49:55] <jevin> Mathieulh, gotcha [21:50:09] <jevin> is his keypair actually blacklisted somewhere though? [21:50:10] <Mathieulh> there is no whitelist for npdrm [21:50:22] <Mathieulh> so it's actually possible to generate valid npdrm self for 3.56+ [21:50:42] <jevin> is it a check in appldr? [21:50:43] <Mathieulh> that tool I made a screenshot of actually does that [21:51:02] <Mathieulh> jevin yeah, it's enforced by lv1 though [21:51:16] <jevin> a hash comparison? [21:51:27] <Mathieulh> yeah it's a hash [21:51:30] <Mathieulh> but I won't say more [21:51:35] <jevin> ok :) [21:51:55] <Mathieulh> everything you need is in the 3.56 fw :p [21:52:16] <jevin> rgr, i will poke around later [21:52:34] <jevin> the checks are unmodified in 3.60+? [21:52:43] <jevin> + new keys of course [21:52:51] <Mathieulh> same checks [21:54:53] <Mathieulh> jevin you won't get around crafting valid 3.56+ npdrm selfs without a proper makeself tool though [21:57:18] <jevin> would SCE make npdrm selfs work if actually signed? [21:57:25] <jevin> + crypted
