2016-03-02mips/kvm: fix ioctl error handlingMichael S. Tsirkin
Returning directly whatever copy_to_user(...) or copy_from_user(...) returns may not do the right thing if there's a pagefault: copy_to_user/copy_from_user return the number of bytes not copied in this case, but ioctls need to return -EFAULT instead. Fix up kvm on mips to do return copy_to_user(...)) ? -EFAULT : 0; and return copy_from_user(...)) ? -EFAULT : 0; everywhere. Cc: stable@vger.kernel.org Signed-off-by: Michael S.

2016-03-01parisc: Fix ptrace syscall number and return value modificationHelge Deller
Mike Frysinger reported that his ptrace testcase showed strange behaviour on parisc: It was not possible to avoid a syscall and the return value of a syscall couldn't be changed. To modify a syscall number, we were missing to save the new syscall number to gr20 which is then picked up later in assembly again. The effect that the return value couldn't be changed is a side-effect of another bug in the assembly code. When a process is ptraced, userspace expects each syscall to report entrance and exit of a syscall. If a syscall number was given which doesn't exist, we jumped to the normal syscall exit code instead of informing userspace that the (non-existant) syscall exits. This unexpected behaviour confuses userspace and thus the bug was misinterpreted as if we can't change the return value. This patch fixes both problems and was tested on 64bit kernel with 32bit userspace.

2016-03-01phy: micrel: Disable auto negotiation on startupAlexandre Belloni
Disable auto negotiation on init to properly detect an already plugged cable at boot. At boot, when the phy is started, it is in the PHY_UP state. However, if a cable is plugged at boot, because auto negociation is already enabled at the time we get the first interrupt, the phy is already running. But the state machine then switches from PHY_UP to PHY_AN and calls phy_start_aneg(). phy_start_aneg() will not do anything because aneg is already enabled on the phy. It will then wait for a interrupt before going further. This interrupt will never happen unless the cable is unplugged and then replugged. It was working properly before 321beec5047a (net: phy: Use interrupts when available in NOLINK state) because switching to NOLINK meant starting polling the phy, even if IRQ were enabled.

2016-03-01ppp: lock ppp->flags in ppp_read() and ppp_poll()Guillaume Nault
ppp_read() and ppp_poll() can be called concurrently with ppp_ioctl(). In this case, ppp_ioctl() might call ppp_ccp_closed(), which may update ppp->flags while ppp_read() or ppp_poll() is reading it. The update done by ppp_ccp_closed() isn't atomic due to the bit mask operation ('ppp->flags &= ~(SC_CCP_OPEN | SC_CCP_UP)'), so concurrent readers might get transient values. Reading incorrect ppp->flags may disturb the 'ppp->flags & SC_LOOP_TRAFFIC' test in ppp_read() and ppp_poll(), which in turn can lead to improper decision on whether the PPP unit file is ready for reading or not. Since ppp_ccp_closed() is protected by the Rx and Tx locks (with ppp_lock()), taking the Rx lock is enough for ppp_read() and ppp_poll() to guarantee that ppp_ccp_closed() won't update ppp->flags concurrently. The same reasoning applies to ppp->n_channels. The 'n_channels' field can also be written to concurrently by ppp_ioctl() (through ppp_connect_channel() or ppp_disconnect_channel()). These writes aren't atomic (simple increment/decrement), but are protected by both the Rx and Tx locks (like in the ppp->flags case). So holding the Rx lock before reading ppp->n_channels also prevents concurrent writes. Signed-off-by: Guillaume Nault <g.nault@alphalink.fr> Signed-off-by: David S. Miller <davem@davemloft.net>

2016-03-01ALSA: seq: oss: Don't drain at closing a clientTakashi Iwai
The OSS sequencer client tries to drain the pending events at releasing. Unfortunately, as spotted by syzkaller fuzzer, this may lead to an unkillable process state when the event has been queued at the far future. Since the process being released can't be signaled any longer, it remains and waits for the echo-back event in that far future. Back to history, the draining feature was implemented at the time we misinterpreted POSIX definition for blocking file operation. Actually, such a behavior is superfluous at release, and we should just release the device as is instead of keeping it up forever. This patch just removes the draining call that may block the release for too long time unexpectedly.

2016-03-01mac80211: Fix Public Action frame RX in AP modeJouni Malinen
Public Action frames use special rules for how the BSSID field (Address 3) is set. A wildcard BSSID is used in cases where the transmitter and recipient are not members of the same BSS. As such, we need to accept Public Action frames with wildcard BSSID. Commit db8e17324553 ("mac80211: ignore frames between TDLS peers when operating as AP") added a rule that drops Action frames to TDLS-peers based on an Action frame having different DA (Address 1) and BSSID (Address 3) values. This is not correct since it misses the possibility of BSSID being a wildcard BSSID in which case the Address 1 would not necessarily match. Fix this by allowing mac80211 to accept wildcard BSSID in an Action frame when in AP mode.

2016-03-01drm/exynos: dsi: restore support for drm bridgeMarek Szyprowski
This patch fixes issue introduced by commit cf67cc9a29ac19c98bc4fa0e6d14b0c1f592d322 ("drm/exynos: remove struct exynos_drm_display"), which removed assigning of drm bridge to drm encoder. Lack of it caused that no bridge callbacks were called on encoder enable/disable actions. Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>

2016-03-01drm/exynos: mic: convert to component frameworkMarek Szyprowski
MIC is SoC component and important part of kms pipeline on Exynos5433, so convert it to use component framework like other KMS/CRTC drivers. MIC driver is already listed on KMS component driver list in Exynos DRM core, so without this conversion, initialization of Exynos DRM core fails on Exynos 5433 SoC.
