[PATCH] binderfs: use refcount for binder control devices too

by Christian Brauner

Binderfs binder-control devices are cleaned up via binderfs_evict_inode too() which will use refcount_dec_and_test(). However, we missed to set the refcount for binderfs binder-control devices and so we underflowed when the binderfs instance got unmounted. Pretty obvious oversight and should have been part of the more general UAF fix. The good news is that having test cases (suprisingly) helps. Technically, we could detect that we're about to cleanup the binder-control dentry in binderfs_evict_inode() and then simply clean it up. But that makes the assumption that the binder driver itself will never make use of a binderfs binder-control device after the binderfs instance it belongs to has been unmounted and the superblock for it been destroyed. While it is unlikely to ever come to this let's be on the safe side. Performance-wise this also really doesn't matter since the binder-control device is only every really when creating the binderfs filesystem or creating additional binder devices. Both operations are pretty rare.

[PATCH] ath9k: Handle txpower changes even when TPC is disabled

by Remi Pommarel

When TPC is disabled IEEE80211_CONF_CHANGE_POWER event can be handled to reconfigure HW's maximum txpower. This fixes 0dBm txpower setting when user attaches to an interface for the first time with the following scenario: ieee80211_do_open() ath9k_add_interface() ath9k_set_txpower() /* Set TX power with not yet initialized sc->hw->conf.power_level */ ieee80211_hw_config() /* Iniatilize sc->hw->conf.power_level and raise IEEE80211_CONF_CHANGE_POWER */ ath9k_config() /* IEEE80211_CONF_CHANGE_POWER is ignored */ This issue can be reproduced with the following: $ modprobe -r ath9k $ modprobe ath9k $ wpa_supplicant -i wlan0 -c /tmp/wpa.conf & $ iw dev /* Here TX power is either 0 or 3 depending on RF chain */ $ killall wpa_supplicant $ iw dev /* TX power goes back to calibrated value and subsequent calls will be fine */ Fixes: 283dd11994cde ("ath9k: add per-vif TX power capability") Cc: stable(a)vger.kernel.org Signed-off-by: Remi Pommarel <repk(a)triplefau.lt> --- drivers/net/wireless/ath/ath9k/main.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/drivers/net/wireless/ath/ath9k/main.c b/drivers/net/wireless/ath/ath9k/main.c index 0548aa3702e3..ef2b856670e1 100644 --- a/drivers/net/wireless/ath/ath9k/main.c +++ b/drivers/net/wireless/ath/ath9k/main.c @@ -1457,6 +1457,9 @@ static int ath9k_config(struct ieee80211_hw *hw, u32 changed) ath_chanctx_set_channel(sc, ctx, &hw->conf.chandef); } + if (changed & IEEE80211_CONF_CHANGE_POWER) + ath9k_set_txpower(sc, NULL); + mutex_unlock(&sc->mutex); ath9k_ps_restore(sc); -- 2.25.0

[tip: x86/urgent] x86/ioremap: Map EFI runtime services data as encrypted for SEV

by tip-bot2 for Tom Lendacky

The following commit has been merged into the x86/urgent branch of tip: Commit-ID: 985e537a4082b4635754a57f4f95430790afee6a Gitweb: https://git.kernel.org/tip/985e537a4082b4635754a57f4f95430790afee6a Author: Tom Lendacky <thomas.lendacky(a)amd.com> AuthorDate: Tue, 10 Mar 2020 18:35:57 +01:00 Committer: Borislav Petkov <bp(a)suse.de> CommitterDate: Wed, 11 Mar 2020 15:54:54 +01:00 x86/ioremap: Map EFI runtime services data as encrypted for SEV The dmidecode program fails to properly decode the SMBIOS data supplied by OVMF/UEFI when running in an SEV guest. The SMBIOS area, under SEV, is encrypted and resides in reserved memory that is marked as EFI runtime services data. As a result, when memremap() is attempted for the SMBIOS data, it can't be mapped as regular RAM (through try_ram_remap()) and, since the address isn't part of the iomem resources list, it isn't mapped encrypted through the fallback ioremap(). Add a new __ioremap_check_other() to deal with memory types like EFI_RUNTIME_SERVICES_DATA which are not covered by the resource ranges. This allows any runtime services data which has been created encrypted, to be mapped encrypted too.

[PATCH 2/2] usb: typec: ucsi: displayport: Fix a potential race during registration

Locking the connector in ucsi_register_displayport() to make sure that nothing can access the displayport alternate mode before the function has finished and the alternate mode is actually ready.

[PATCH 1/2] usb: typec: ucsi: displayport: Fix NULL pointer dereference

by Heikki Krogerus

If the registration of the DisplayPort was not successful, or if the port does not support DisplayPort alt mode in the first place, the function ucsi_displayport_remove_partner() will fail with NULL pointer dereference when it attempts to access the driver data. Adding a check to the function to make sure there really is driver data for the device before modifying it.

[PATCH] gpiolib: Fix irq_disable() semantics

by Linus Walleij

The implementation if .irq_disable() which kicks in between the gpiolib and the driver is not properly mimicking the expected semantics of the irqchip core: the irqchip will call .irq_disable() if that exists, else it will call mask_irq() which first checks if .irq_mask() is defined before calling it. Since we are calling it unconditionally, we get this bug from drivers/pinctrl/qcom/pinctrl-ssbi-gpio.c, as it only defines .irq_mask_ack and not .irq_mask: Unable to handle kernel NULL pointer dereference at virtual address 00000000 pgd = (ptrval) (...) PC is at 0x0 LR is at gpiochip_irq_disable+0x20/0x30 Fix this by only calling .irq_mask() if it exists.
