Patch "ALSA: seq: Don't allow resizing pool in use" has been added to the 4.14-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled ALSA: seq: Don't allow resizing pool in use to the 4.14-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: alsa-seq-don-t-allow-resizing-pool-in-use.patch and it can be found in the queue-4.14 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From d85739367c6d56e475c281945c68fdb05ca74b4c Mon Sep 17 00:00:00 2001 From: Takashi Iwai <tiwai(a)suse.de> Date: Mon, 5 Mar 2018 22:00:55 +0100 Subject: ALSA: seq: Don't allow resizing pool in use MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit From: Takashi Iwai <tiwai(a)suse.de> commit d85739367c6d56e475c281945c68fdb05ca74b4c upstream. This is a fix for a (sort of) fallout in the recent commit d15d662e89fc ("ALSA: seq: Fix racy pool initializations") for CVE-2018-1000004. As the pool resize deletes the existing cells, it may lead to a race when another thread is writing concurrently, eventually resulting a UAF. A simple workaround is not to allow the pool resizing when the pool is in use. It's an invalid behavior in anyway.

The dock line-out pin (NID 0x17 of ALC3254 codec) on Dell Precision 7520 may route to three different DACs, 0x02, 0x03 and 0x06. The first two DACS have the volume amp controls while the last one doesn't. And unfortunately, the auto-parser assigns this pin to DAC3, resulting in the non-working volume control for the line out. Fix it by disabling the routing to DAC3 on the corresponding pin.

This platform was only one phone Jack. Add dummy lineout verb to fix automute mode disable. This just the workaround. [ More background information: since the platform has only a headphone jack without speaker, the driver doesn't create the auto-mute control. Meanwhile we do update the headset mode via the automute hook in the driver, thus with this setup, the headset won't be updated any longer. By adding a dummy line-out pin here, the auto-mute is added by the driver, and the headset update is triggered properly. Note that this is different from the other ALC274_FIXUP_DELL_AIO_LINEOUT_VERB, which has the real line-out pin, while this quirk adds a dummy line-out pin. -- tiwai ] Signed-off-by: Kailang Yang <kailang(a)realtek.com> Cc: <stable(a)vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai(a)suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> --- sound/pci/hda/patch_realtek.c | 11 +++++++++++ 1 file changed, 11 insertions(+) --- a/sound/pci/hda/patch_realtek.c +++ b/sound/pci/hda/patch_realtek.c @@ -5340,6 +5340,7 @@ enum { ALC274_FIXUP_DELL_BIND_DACS, ALC274_FIXUP_DELL_AIO_LINEOUT_VERB, ALC298_FIXUP_TPT470_DOCK, + ALC255_FIXUP_DUMMY_LINEOUT_VERB, }; static const struct hda_fixup alc269_fixups[] = { @@ -6187,6 +6188,15 @@ static const struct hda_fixup alc269_fix .chained = true, .chain_id = ALC293_FIXUP_LENOVO_SPK_NOISE }, + [ALC255_FIXUP_DUMMY_LINEOUT_VERB] = { + .type = HDA_FIXUP_PINS, + .v.pins = (const struct hda_pintbl[]) { + { 0x14, 0x0201101f }, + { } + }, + .chained = true, + .chain_id = ALC255_FIXUP_DELL1_MIC_NO_PRESENCE + }, }; static const struct snd_pci_quirk alc269_fixup_tbl[] = { @@ -6240,6 +6250,7 @@ static const struct snd_pci_quirk alc269 SND_PCI_QUIRK(0x1028, 0x082a, "Dell XPS 13 9360", ALC256_FIXUP_DELL_XPS_13_HEADPHONE_NOISE), SND_PCI_QUIRK(0x1028, 0x084b, "Dell", ALC274_FIXUP_DELL_AIO_LINEOUT_VERB), SND_PCI_QUIRK(0x1028, 0x084e, "Dell", ALC274_FIXUP_DELL_AIO_LINEOUT_VERB), + SND_PCI_QUIRK(0x1028, 0x0873, "Dell Precision 3930", ALC255_FIXUP_DUMMY_LINEOUT_VERB), SND_PCI_QUIRK(0x1028, 0x164a, "Dell", ALC293_FIXUP_DELL1_MIC_NO_PRESENCE), SND_PCI_QUIRK(0x1028, 0x164b, "Dell", ALC293_FIXUP_DELL1_MIC_NO_PRESENCE), SND_PCI_QUIRK(0x103c, 0x1586, "HP", ALC269_FIXUP_HP_MUTE_LED_MIC2), Patches currently in stable-queue which might be from kailang(a)realtek.com are queue-4.14/alsa-hda-realtek-add-support-headset-mode-for-dell-wyse.patch queue-4.14/alsa-hda-realtek-add-headset-mode-support-for-dell-laptop.patch queue-4.14/alsa-hda-fix-a-wrong-fixup-for-alc289-on-dell-machines.patch

With the alc289, the Pin 0x1b is Headphone-Mic, so we should assign ALC269_FIXUP_DELL4_MIC_NO_PRESENCE rather than ALC225_FIXUP_DELL1_MIC_NO_PRESENCE to it. And this change is suggested by Kailang of Realtek and is verified on the machine.

Patch "x86/MCE: Serialize sysfs changes" has been added to the 3.18-stable tree

This is a note to let you know that I've just added the patch titled x86/MCE: Serialize sysfs changes to the 3.18-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: x86-mce-serialize-sysfs-changes.patch and it can be found in the queue-3.18 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From b3b7c4795ccab5be71f080774c45bbbcc75c2aaf Mon Sep 17 00:00:00 2001 From: Seunghun Han <kkamagui(a)gmail.com> Date: Tue, 6 Mar 2018 15:21:43 +0100 Subject: x86/MCE: Serialize sysfs changes From: Seunghun Han <kkamagui(a)gmail.com> commit b3b7c4795ccab5be71f080774c45bbbcc75c2aaf upstream. The check_interval file in /sys/devices/system/machinecheck/machinecheck<cpu number> directory is a global timer value for MCE polling. If it is changed by one CPU, mce_restart() broadcasts the event to other CPUs to delete and restart the MCE polling timer and __mcheck_cpu_init_timer() reinitializes the mce_timer variable. If more than one CPU writes a specific value to the check_interval file concurrently, mce_timer is not protected from such concurrent accesses and all kinds of explosions happen. Since only root can write to those sysfs variables, the issue is not a big deal security-wise. However, concurrent writes to these configuration variables is void of reason so the proper thing to do is to serialize the access with a mutex.
