Dopamine 2.4: Fix for spinlock panics, miscellaneous improvements
13 days uptime without a single panic or high ram usage or battery 🔋 draining or bugs WOUAH 😎
Dopamine 2.3~28aa20 ✅ beta
This version has fixed bugs 👍
After almost 2 years of on-and-off trying to workaround the spinlock panic bug (race condition) on iOS 15 arm64e, I have finally managed to trigger the bug on-demand.
TimeBomb 2: Spinlock panic on demand
https://www.reddit.com/r/jailbreak/comments/1ip8rj0/timebomb_2_spinlock_panic_on_demand/
As usual this workaround did not work.
I believe the reason is that my "shared cache mlock" solution does not fully work, since I got one panic where the kernel tried to fault in a page that should definitely have been wired down. It's annoying because given this ability I believe it would work, but I cannot see any way I could possibly properly wire down DSC pages, even wiring down executable pages in general seems to be outright impossible based on comments in XNU.
So I think I'm going to give up and release 2.3.1 without this workaround and without integrated oldabi and just give up on this issue. Wasted too much time on this already anyways.
Dopamine 2.3 is out now
https://github.com/opa334/Dopamine/releases/tag/2.3
Changelog:
- Add an oldABI implementation that doesn't use C function hooks and therefore (unlike the ellekit oldABI) should not affect spinlock panics on iOS 15 arm64e, accessible via Dopamine settings as "Allow Legacy arm64e Libraries" (NOTE: There is no need to remove the old ellekit oldABI package, since if the option is turned on, the ellekit oldABI will automatically be disabled. This is done because some tweaks may depend on the oldABI package.)
- Rework forkfix to not do any C function hooks on iOS 15 arm64e in an attempt to reduce spinlock panics on iOS 15 arm64e
- Wire down libraries whose text page faults are known to cause the stock bug (race condition) that results in a spinlock panic on iOS 15 arm64e, this should reduce spinlock panics by a considerable amount (Note that there is nothing special about these libraries except that they are used in a lot of processes at the same time, so there might still be more triggers for the issue) ((It still has to be confirmed whether this change actually reduces spinlock panics, but in theory it should))
- Fix a rare system deadlock during "Initializing Jailbreak"
Aaand I just submitted 1.5.1 to fix an issue where all arm64e processes would crash loop on iOS <15, wooops (Apparently dyld_dynamic_interpose never worked on arm64e, which is probably why Apple stubbed it out in iOS 15).
If you have TrollStore on your device then ur lucky & you’ve to know that it’s the craziest thing which happened to the jailbreak community🥰
FYI : TrollStore is Jailed iOS app that can install IPAs permanently with arbitary entitlements and root helpers because it trolls Apple
Certainly we all do remember the day TrollStore got released and it’s was mind blowing to see this jailed iOS app 🤩
Thanks @opa334 everyone involved
The community won’t forget the gift and everything you’ve done especially Dopamine on iOS 16 🫡
In other news, Choicy 1.5 is out with the changes described here.
