2019-03-22xhci: Don't let USB3 ports stuck in polling state prevent suspendMathias Nyman
Commit 2f31a67f01a8 ("usb: xhci: Prevent bus suspend if a port connect change or polling state is detected") was intended to prevent ports that were still link training from being forced to U3 suspend state mid enumeration. This solved enumeration issues for devices with slow link training. Turns out some devices are stuck in the link training/polling state, and thus that patch will prevent suspend completely for these devices. This is seen with USB3 card readers in some MacBooks. Instead of preventing suspend, give some time to complete the link training. On successful training the port will end up as connected and enabled. If port instead is stuck in link training the bus suspend will continue suspending after 360ms (10 * 36ms) timeout (tPollingLFPSTimeout).

Host controller driver only checks for U0 state, and might miss the finished resume, leaving flags unclear and skip notifying usb code of the wake.

2019-03-22ALSA: pcm: Fix possible OOB access in PCM oss pluginsTakashi Iwai
The PCM OSS emulation converts and transfers the data on the fly via "plugins". The data is converted over the dynamically allocated buffer for each plugin, and recently syzkaller caught OOB in this flow. Although the bisection by syzbot pointed out to the commit 65766ee0bf7f ("ALSA: oss: Use kvzalloc() for local buffer allocations"), this is merely a commit to replace vmalloc() with kvmalloc(), hence it can't be the cause. The further debug action revealed that this happens in the case where a slave PCM doesn't support only the stereo channels while the OSS stream is set up for a mono channel. Below is a brief explanation: At each OSS parameter change, the driver sets up the PCM hw_params again in snd_pcm_oss_change_params_lock(). This is also the place where plugins are created and local buffers are allocated. The problem is that the plugins are created before the final hw_params is determined. Namely, two snd_pcm_hw_param_near() calls for setting the period size and periods may influence on the final result of channels, rates, etc, too, while the current code has already created plugins beforehand with the premature values. So, the plugin believes that channels=1, while the actual I/O is with channels=2, which makes the driver reading/writing over the allocated buffer size. The fix is simply to move the plugin allocation code after the final hw_params call.

2019-03-22iwlwifi: mvm: fix TX crypto on 22560+ devicesJohannes Berg
In the old days, we could transmit with HW crypto with an arbitrary key by filling it into TX_CMD. This was broken first with the advent of CCMP/GCMP-256 keys which don't fit there. This was broken *again* with the newer TX_CMD format on 22560+, where we simply cannot pass key material anymore. However, we forgot to update all the cases when we get a key from mac80211 and don't program it into the hardware but still return 0 for HW crypto on TX. In AP mode with WEP, we tried to fix this by programming the keys separately for each station later, but this ultimately turns out to be buggy, for example now it leaks memory when we have more than one WEP key. Fix this by simply using only SW crypto for WEP in newer devices by returning -EOPNOTSUPP instead of trying to program WEP keys later.

2019-03-21bpf: verifier: propagate liveness on all framesJakub Kicinski
Commit 7640ead93924 ("bpf: verifier: make sure callees don't prune with caller differences") connected up parentage chains of all frames of the stack. It didn't, however, ensure propagate_liveness() propagates all liveness information along those chains. This means pruning happening in the callee may generate explored states with incomplete liveness for the chains in lower frames of the stack. The included selftest is similar to the prior one from commit 7640ead93924 ("bpf: verifier: make sure callees don't prune with caller differences"), where callee would prune regardless of the difference in r8 state. Now we also initialize r9 to 0 or 1 based on a result from get_random(). r9 is never read so the walk with r9 = 0 gets pruned (correctly) after the walk with r9 = 1 completes. The selftest is so arranged that the pruning will happen in the callee. Since callee does not propagate read marks of r8, the explored state at the pruning point prior to the callee will now ignore r8. Propagate liveness on all frames of the stack when pruning.
