2020-12-02net/x25: prevent a couple of overflowsDan Carpenter
The .x25_addr[] address comes from the user and is not necessarily NUL terminated. This leads to a couple problems. The first problem is that the strlen() in x25_bind() can read beyond the end of the buffer. The second problem is more subtle and could result in memory corruption. The call tree is: x25_connect() --> x25_write_internal() --> x25_addr_aton() The .x25_addr[] buffers are copied to the "addresses" buffer from x25_write_internal() so it will lead to stack corruption. Verify that the strings are NUL terminated and return -EINVAL if they are not.

Without these patches, lockdep is hopelessly unreliable in some configurations [1,2] and syzkaller is therefore not a lot of use because it's so noisy. Although much of this has always been broken, it appears to have been exposed more readily by other changes such as 044d0d6de9f5 ("lockdep: Only trace IRQ edges") and general lockdep improvements around IRQ tracing and NMIs. Fixing this properly required moving much of the instrumentation hooks from our entry assembly into C, which Mark has been working on for the last few weeks. We're not quite ready to move to the recently added generic functions yet, but the code here has been deliberately written to mimic that closely so we can look at cleaning things up once we have a bit more breathing room. Having said all that, the second version of these patches was posted last week and I pushed it into our CI (kernelci and cki) along with a commit which forced on PROVE_LOCKING, NOHZ_FULL and CONTEXT_TRACKING_FORCE.

Add modifications for A2DP interoperability issue of TWS earphones. Some TWS earphones has low buffer size, so it's necessary to reduce the slot period to let it get data more frequently. (e.g. use 4-slot to replace the original 2-slot method).

2020-12-02rtw88: coex: add action for coexistence in hardware initialChing-Te Ku
The original setting misses some necessary configuration. Make coexistence slot align to beacon and check the connection situation to know if we need to extend WLAN slot or not.

2020-12-02rtw88: coex: add function to avoid cck lockChing-Te Ku
Some AP will not follow the power save request, or it cannot stop transmission until its queue is empty. It may bring the decreasing of data rate. WLAN firmware will count is the AP still leaked packet after power save handshake was done or not to enable WLAN slot extend mechanism. The extend WLAN slot mechanism will extend the WLAN slot after power save handshake, 5 ms per times, maximum is 5 times to received the leaked packet to avoid the rate lower down. And if the transmission was already locked at CCK rate. The extended WLAN slot can also increase the opportunity that we can received the CCK's long packet and be released from CCK rate. While BT multi-link status was finished, there is possible that it still has some packet remained for seconds. Add a timer to remain the multi-link mechanism to protect WLAN Rx.

2020-12-02rtw88: coex: change the coexistence mechanism for HIDChing-Te Ku
Add TDMA slot type setting for later usage. Since the transmission of HID profile is very frequently, it may bring a big impact to WLAN performance. To change slot type, it can make mechanism be more flexible.

2020-12-02Revert "rtl8xxxu: Add Buffalo WI-U3-866D to list of supported devices"Tokunori Ikegami
This reverts commit 28606150768a20b291a35dbbbb0ab4dd7d4739db. Since actually Buffalo WI-U3-866D is falied to power on with the change. The rtl8812au driver code to power on is same with the rtl8821a code. But the rtl8821ae included rtl8821a does not support USB interface. So seems that rtl8812au should be supported by rt1l8821a code with USB.
