The mgmt_ev_device_connected signal must be sent before any event indications happen for sockets associated with the connection. Otherwise e.g. device authorization for the sockets will fail with ENOTCONN as user space things that there is no baseband link. This patch fixes the issue by ensuring that the device_connected event if sent (if it hasn't been so already) as soon as the first ACL data packet arrives from the remote device.

It fixes L2CAP socket based security level elevation during a connection. The HID profile needs this (for keyboards) and it is the only way to achieve the security level elevation when using the management interface to talk to the kernel (hence the management enabling patch being the one that exposes this issue). It enables the userspace a security level change when the socket is already connected and create a way to notify the socket the result of the request. At the moment of the request the socket is made non writable, if the request fails the connections closes, otherwise the socket is made writable again, POLL_OUT is emmited.

So we have another case of paca->irq_happened getting out of sync with the HW irq state. This can happen when a perfmon interrupt occurs while soft disabled, as it will return to a soft disabled but hard enabled context while leaving a stale PACA_IRQ_HARD_DIS flag set. This patch fixes it, and also adds a test for the condition of those flags being out of sync in arch_local_irq_restore() when CONFIG_TRACE_IRQFLAGS is enabled. This helps catching those gremlins faster (and so far I can't seem see any anymore, so that's good news). Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org>

Since commit 3aba891d, bonding processes LACP frames (802.3ad mode) with bond_handle_frame(). Currently a copy of the skb is made and the original is left to be processed by other rx_handlers and the rest of the network stack by returning RX_HANDLER_ANOTHER. As there is no protocol handler for PKT_TYPE_LACPDU, the frame is dropped and dev->rx_dropped increased. Fix this by making bond_handle_frame() return RX_HANDLER_CONSUMED if bonding has processed the LACP frame. Signed-off-by: NJiri Bohac <jbohac@suse.cz> Signed-off-by: NDavid S.

In 2009 Philip Reiser notied that a few users of netlink connector interface needed a capability check and added the idiom cap_raised(nsp->eff_cap, CAP_SYS_ADMIN) to a few of them, on the premise that netlink was asynchronous. In 2011 Patrick McHardy noticed we were being silly because netlink is synchronous and removed eff_cap from the netlink_skb_params and changed the idiom to cap_raised(current_cap(), CAP_SYS_ADMIN). Looking at those spots with a fresh eye we should be calling capable(CAP_SYS_ADMIN). The only reason I can see for not calling capable is that it once appeared we were not in the same task as the caller which would have made calling capable() impossible. In the initial user_namespace the only difference between between cap_raised(current_cap(), CAP_SYS_ADMIN) and capable(CAP_SYS_ADMIN) are a few sanity checks and the fact that capable(CAP_SYS_ADMIN) sets PF_SUPERPRIV if we use the capability. Since we are going to be using root privilege setting PF_SUPERPRIV seems the right thing to do. The motivation for this that patch is that in a child user namespace cap_raised(current_cap(),...) tests your capabilities with respect to that child user namespace not capabilities in the initial user namespace and thus will allow processes that should be unprivielged to use the kernel services that are only protected with cap_raised(current_cap(),..). To fix possible user_namespace issues and to just clean up the code replace cap_raised(current_cap(), CAP_SYS_ADMIN) with capable(CAP_SYS_ADMIN). Signed-off-by: NEric W.

The NEQ interrupt is only triggered when there was no previous pending interrupt. If we request irq handling after an interrupt has occurred, we will never get an interrupt until we call H_RESET_EVENTS. Events seem to be cleared when we first register the NEQ. So, when we requested irq handling right after registering it, a possible race with an interrupt was much less likely. Now, there is a chance we may lose this race and never get any events. The fix here is to poll and acknowledge any events that might have happened right after registering the irq handler.
