8.1.0

2019-08-06T09:52:02Z

Minus256: /* See Also */

The Switch 8.1.0 system update was released on June 17, 2019. This Switch update was released for the following regions: ALL.

Security flaws fixed: yes.

==Change-log==
[https://en-americas-support.nintendo.com/app/answers/detail/a_id/22525/p/897 Official] ALL change-log:
* General system stability improvements to enhance the user's experience.
*

==FIRM==
All files in RomFS were updated.

====Package1ldr====
package1ldr was updated. The TSEC secureboot firmware was updated.

====NX_BOOTLOADER====
NX bootloader was updated.

<check back later for diff>

====Secure Monitor====
The Secure Monitor was updated.

* The SE key read disable function no longer writes zero to AES_KEY_READ_DISABLE/RSA_KEY_READ_DISABLE.
* Functions for locking/checking PMC secure scratch now have additional bitmasks 0x40/0x80 for locking more secure scratch registers.
* NVDEC/TSECB access to the kernel carveout was removed.
* On suspend (SC7 Entry), SWR_USBD_RST is now checked, and AHB arbitration disable is now checked to be COP, ARC, USB, USB2.
** This further mitigates against Deja Vu.
* TZ/SE context save logic has been changed.
** The context save function now first generates 16 random bytes, and securely saves them to scratch (using the usual write-writelock-check-readlock-checklocked pattern).
** It then generates a random aes-256 key, and derives an actual encryption/MAC key by decrypting the random data with that key.
*** Previously, it generated a random aes-256 key and used it directly.
*** This prevents attacks that might coerce the usage of a specific aes-256 key instead of a random one.
** Calls into the check scratch locked/lock scratch function which previously passed one bitmask at a time now pass multiple
*** Accordingly, the lock/check locked functions now support multiple bitmasks instead of single bitmasks at a time.
* The function that initializes the SE/derives keys now sets flag 0x100 on AES keyslots 8-15, and RSA keyslots 0-1.

====Kernel====
Kernel was not changed.

====Warmboot====
* The firmware revision magic was changed from 0x129 to 0x14A.
* Security Engine state validation was changed (first six keyslots now expected to read zeroes instead of FFs).
* <check back for more diffs later>

====FIRM Sysmodules====
FIRM sysmodules were updated. Specific diffs available below:

=====[[Boot]]=====
Only GNU build hash was updated.

=====[[Filesystem services|FS]]=====
Only GNU build hash was updated.

=====[[Loader services|Loader]]=====
*ldr:pm->CreateProcess() now performs additional validation on the NPDM header.
** When the title id is one of certain hardcoded titles, Loader now validates that the version field at NPDM header is non-zero. This prevents selectively downgrading those titles to versions vulnerable to known exploits.
** The titles checked are:
*** settings
*** bus
*** audio
*** nvservices
*** ns
*** ssl
*** es
*** creport
*** ro

=====[[NCM services|NCM]]=====
Only GNU build hash was updated.

=====[[Process Manager services|PM]]=====
Only GNU build hash was updated.

=====[[Services_API|SM]]=====
SM was not updated.

=====[[SPL services|SPL]]=====
SPL was not updated.

==System Titles==
Updated titles:
* Sysmodules:
** settings Rebuilt.
** bus Identical codebin.
** bcat .text updated.
** hid .text updated.
** audio Identical codebin.
** wlan .text updated.
** nvservices Only GNU build hash was updated.
** nvnflinger .text updated.
** account .text updated.
** ns .text updated.
** am .text updated.
** ssl Rebuilt.
** vi .text updated.
** es .text updated.
** fatal .text updated.
** creport Identical codebin.
** ro Identical codebin.
** grc .text updated.
* ErrorMessage, BrowserDll, [[System_Version_Title]], FIRM, qlaunch, web-applets (main codebin rebuilt), and RebootlessSystemUpdateVersion.

No changes with IPC service commands.

Titles' RomFS changes, besides [[System_Version_Title]]:
* ErrorMessage: Error 2124-4517 was updated with actual strings etc. "/2181/4017/common" and "/DatabaseInfo" were updated.
* BrowserDll: the NROs and buildinfo were updated.
* RebootlessSystemUpdateVersion: The "/version" file was updated.
* qlaunch: "/lyt/Notification.szs" was updated.
* Web-applets: "/buildinfo/buildinfo.dat" and "/.nrr/netfront.nrr" were updated.

==Keys==
Keys were updated.
