patch "android: binder: fix the race mmap and alloc_new_buf_locked" added to char-misc-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled android: binder: fix the race mmap and alloc_new_buf_locked to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From da1b9564e85b1d7baf66cbfabcab27e183a1db63 Mon Sep 17 00:00:00 2001 From: Minchan Kim <minchan(a)kernel.org> Date: Thu, 23 Aug 2018 14:29:56 +0900 Subject: android: binder: fix the race mmap and alloc_new_buf_locked There is RaceFuzzer report like below because we have no lock to close below the race between binder_mmap and binder_alloc_new_buf_locked.

However the removal is not instant. A client may be visible on the client list when the mei driver requests for enumeration, while the subsequent request for properties will be answered with client not found error value. The default behavior for an error is to perform client reset while this error is harmless and the link reset should be prevented. This issue started to be visible due to suspend/resume timing changes. Currently reported only on the Haswell based system.

[PATCH for-rc 0/2] IB/hfi1: RC patches

by Dennis Dalessandro

Hi Doug and Jason, Here are two patches that should probably land in the RC. The first one ensures we don't index beyond the end of an array. The other is more subtle but arguably more important. The bug it fixes results in incorrect IRQ bits to be set and the result is we do not get an interrupt for an error and have to wait for another interrupt to fire to see said error. --- Dennis Dalessandro (1): IB/hfi1: Ensure ucast_dlid access doesnt exceed bounds Michael J.

[PATCH] of: fix phandle cache creation for DTs with no phandles

by Rob Herring

With commit 0b3ce78e90fc ("of: cache phandle nodes to reduce cost of of_find_node_by_phandle()"), a G3 PowerMac fails to boot. The root cause is the DT for this system has no phandle properties when booted with BootX. of_populate_phandle_cache() does not handle the case of no phandles correctly. The problem is roundup_pow_of_two() for 0 is undefined. The implementation subtracts 1 underflowing and then things are in the weeds.

Missing mei patches

by Georg Müller

Is there a chance of getting the two mei patches into 4.19 and 4.18.y? https://www.spinics.net/lists/stable/msg253484.html https://www.spinics.net/lists/stable/msg253485.html Bugzilla entries: https://bugzilla.kernel.org/show_bug.cgi?id=200455 https://bugzilla.redhat.com/show_bug.cgi?id=1597481 Even if maybe only a couple of systems are affected, this is causing a dead system on second suspend which could cause data loss. Maybe the patches were not merged because of a typo in the subject (4.9 instead of 4.19)? Best regards, Georg
