From 0e3443d157b9d18bc1d9d6a26becb1ff930efa0d Mon Sep 17 00:00:00 2001 From: Li Li Date: Wed, 7 Dec 2022 21:51:19 -0800 Subject: Support BR_TRANSACTION_PENDING_FROZEN When an async binder transaction is sent to a frozen process, the kernel binder driver returns BR_TRANSACTION_PENDING_FROZEN. This tells the user space app that pending async binder transaction won't be processed until the target process is unfrozen at an unspecified time in the future. Generally all binder transactions to frozen processes should be avoided to prevent the kernel async binder buffer from running out. Bug: 253913841 Test: freeze process and check logcat Change-Id: Ie0191b0b3b6b0a4a8481f27f3b0e64e4c1279cb5 --- libs/binder/IPCThreadState.cpp | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'libs/binder/IPCThreadState.cpp') diff --git a/libs/binder/IPCThreadState.cpp b/libs/binder/IPCThreadState.cpp index 77703749a1..c0f3e3060e 100644 --- a/libs/binder/IPCThreadState.cpp +++ b/libs/binder/IPCThreadState.cpp @@ -1017,6 +1017,10 @@ status_t IPCThreadState::waitForResponse(Parcel *reply, status_t *acquireResult) if (!reply && !acquireResult) goto finish; break; + case BR_TRANSACTION_PENDING_FROZEN: + ALOGW("Sending oneway calls to frozen process."); + goto finish; + case BR_DEAD_REPLY: err = DEAD_OBJECT; goto finish; -- cgit v1.2.3-59-g8ed1b
