2023-04-20wifi: iwlwifi: mvm: fix RFKILL report when driver is going downAvraham Stern
When CSME takes ownership, the driver sets RFKILL on, and this triggers driver unload and sending the confirmation SAP message. However, when IWL_MVM_MEI_REPORT_RFKILL is set, RFKILL was not reported and as a result, the driver did not confirm the ownership transition. Fix it.

2023-04-20wifi: iwlwifi: mei: re-ask for ownership after it was taken by CSMEAvraham Stern
When the host disconnects from the AP CSME takes ownership right away. Since the driver never asks for ownership again wifi is left in rfkill until CSME releases the NIC, although in many cases the host could re-connect shortly after the disconnection. To allow the host to recover from occasional disconnection, re-ask for ownership to let the host connect again. Allow one minute before re-asking for ownership to avoid too frequent ownership transitions.

When mei filtered scan is performed, it must find the AP on the first scan, otherwise CSME will take the ownership of the NIC. Make this scan more aggressive by scanning the channel the AP is supposed to be on (as reported by CSME) several times.

2023-04-20wifi: iwlwifi: modify scan request and results when in link protectionAvraham Stern
When CSME is connected and has link protection set, the driver must connect to the same AP CSME is connected to. When in link protection, modify scan request parameters to include only the channel of the AP CSME is connected to and scan for the same SSID. In addition, filter the scan results to include only results from the same AP. This will make sure the driver will connect to the same AP and will do it fast enough to keep the session alive.

2023-04-20wifi: iwlwifi: mvm: fix MIC removal confusionJohannes Berg
The RADA/firmware collaborate on MIC stripping in the following way: - the firmware fills the IWL_RX_MPDU_MFLG1_MIC_CRC_LEN_MASK value for how many words need to be removed at the end of the frame, CRC and, if decryption was done, MIC - if the RADA is active, it will - remove that much from the end of the frame - zero the value in IWL_RX_MPDU_MFLG1_MIC_CRC_LEN_MASK As a consequence, the only thing the driver should need to do is to - unconditionally tell mac80211 that the MIC was removed if decryption was already done - remove as much as IWL_RX_MPDU_MFLG1_MIC_CRC_LEN_MASK says at the end of the frame, since either RADA did it and then the value is 0, or RADA was disabled and then the value is whatever should be removed to strip both CRC & MIC However, all this code was historically grown and getting a bit confused. Originally, we were indicating that the MIC was not stripped, which is the version of the code upstreamed in commit 780e87c29e77 ("iwlwifi: mvm: add 9000 series RX processing") which indicated RX_FLAG_DECRYPTED in iwl_mvm_rx_crypto(). We later had a commit to change that to also indicate that the MIC was stripped, adding RX_FLAG_MIC_STRIPPED. However, this was then "fixed" later to only do that conditionally on RADA being enabled, since otherwise RADA didn't strip the MIC bytes yet. At the time, we were also always including the FCS if the RADA was not enabled, so that was still broken wrt. the FCS if the RADA isn't enabled - but that's a pretty rare case. Notably though, it does happen for management frames, where we do need to remove the MIC and CRC but the RADA is disabled. Later, in commit 40a0b38d7a7f ("iwlwifi: mvm: Fix calculation of frame length"), we changed this again, upstream this was just a single commit, but internally it was split into first the correct commit and then an additional fix that reduced the number of bytes that are removed by crypt_len. Note that this is clearly wrong since crypt_len indicates the length of the PN header (always 8), not the length of the MIC (8 or 16 depending on algorithm). However, this additional fix mostly canceled the other bugs, apart from the confusion about the size of the MIC. To fix this correctly, remove all those additional workarounds. We really should always indicate to mac80211 the MIC was stripped (it cannot use it anyway if decryption was already done), and also always actually remove it and the CRC regardless of the RADA being enabled or not. That's simple though, the value indicated in the metadata is zeroed by the RADA if it's enabled and used the value, so there's no need to check if it's enabled or not. Notably then, this fixes the MIC size confusion, letting us receive GCMP-256 encrypted management frames correctly that would otherwise be reported to mac80211 8 bytes too short since the RADA is turned off for them, crypt_len is 8, but the MIC size is 16, so when we do the adjustment based on IWL_RX_MPDU_MFLG1_MIC_CRC_LEN_MASK (which indicates 20 bytes to remove) we remove 12 bytes but indicate then to mac80211 the MIC is still present, so mac80211 again removes the MIC of 16 bytes, for an overall removal of 28 rather than 20 bytes.

2023-04-20net: bridge: switchdev: don't notify FDB entries with "master dynamic"Vladimir Oltean
There is a structural problem in switchdev, where the flag bits in struct switchdev_notifier_fdb_info (added_by_user, is_local etc) only represent a simplified / denatured view of what's in struct net_bridge_fdb_entry :: flags (BR_FDB_ADDED_BY_USER, BR_FDB_LOCAL etc). Each time we want to pass more information about struct net_bridge_fdb_entry :: flags to struct switchdev_notifier_fdb_info (here, BR_FDB_STATIC), we find that FDB entries were already notified to switchdev with no regard to this flag, and thus, switchdev drivers had no indication whether the notified entries were static or not. For example, this command: ip link add br0 type bridge && ip link set swp0 master br0 bridge fdb add dev swp0 00:01:02:03:04:05 master dynamic has never worked as intended with switchdev. It causes a struct net_bridge_fdb_entry to be passed to br_switchdev_fdb_notify() which has a single flag set: BR_FDB_ADDED_BY_USER. This is further passed to the switchdev notifier chain, where interested drivers have no choice but to assume this is a static (does not age) and sticky (does not migrate) FDB entry. So currently, all drivers offload it to hardware as such, as can be seen below ("offload" is set). bridge fdb get 00:01:02:03:04:05 dev swp0 master 00:01:02:03:04:05 dev swp0 offload master br0 The software FDB entry expires $ageing_time centiseconds after the kernel last sees a packet with this MAC SA, and the bridge notifies its deletion as well, so it eventually disappears from hardware too. This is a problem, because it is actually desirable to start offloading "master dynamic" FDB entries correctly - they should expire $ageing_time centiseconds after the *hardware* port last sees a packet with this MAC SA - and this is how the current incorrect behavior was discovered. With an offloaded data plane, it can be expected that software only sees exception path packets, so an otherwise active dynamic FDB entry would be aged out by software sooner than it should. With the change in place, these FDB entries are no longer offloaded: bridge fdb get 00:01:02:03:04:05 dev swp0 master 00:01:02:03:04:05 dev swp0 master br0 and this also constitutes a better way (assuming a backport to stable kernels) for user space to determine whether the kernel has the capability of doing something sane with these or not. As opposed to "master dynamic" FDB entries, on the current behavior of which no one currently depends on (which can be deduced from the lack of kselftests), Ido Schimmel explains that entries with the "extern_learn" flag (BR_FDB_ADDED_BY_EXT_LEARN) should still be notified to switchdev, since the spectrum driver listens to them (and this is kind of okay, because although they are treated identically to "static", they are expected to not age, and to roam).

2023-04-19x86: remove 'zerorest' argument from __copy_user_nocache()Linus Torvalds
Every caller passes in zero, meaning they don't want any partial copy to zero the remainder of the destination buffer. Which is just as well, because the implementation of that function didn't actually even look at that argument, and wasn't even aware it existed, although some misleading comments did mention it still. The 'zerorest' thing is a historical artifact of how "copy_from_user()" worked, in that it would zero the rest of the kernel buffer that it copied into. That zeroing still exists, but it's long since been moved to generic code, and the raw architecture-specific code doesn't do it. See _copy_from_user() in lib/usercopy.c for this all. However, while __copy_user_nocache() shares some history and superficial other similarities with copy_from_user(), it is in many ways also very different. In particular, while the code makes it *look* similar to the generic user copy functions that can copy both to and from user space, and take faults on both reads and writes as a result, __copy_user_nocache() does no such thing at all. __copy_user_nocache() always copies to kernel space, and will never take a page fault on the destination. What *can* happen, though, is that the non-temporal stores take a machine check because one of the use cases is for writing to stable memory, and any memory errors would then take synchronous faults. So __copy_user_nocache() does look a lot like copy_from_user(), but has faulting behavior that is more akin to our old copy_in_user() (which no longer exists, but copied from user space to user space and could fault on both source and destination). And it very much does not have the "zero the end of the destination buffer", since a problem with the destination buffer is very possibly the very source of the partial copy. So this whole thing was just a confusing historical artifact from having shared some code with a completely different function with completely different use cases.

2023-04-19net/handshake: Create a NETLINK service for handling handshake requestsChuck Lever
When a kernel consumer needs a transport layer security session, it first needs a handshake to negotiate and establish a session. This negotiation can be done in user space via one of the several existing library implementations, or it can be done in the kernel. No in-kernel handshake implementations yet exist. In their absence, we add a netlink service that can: a. Notify a user space daemon that a handshake is needed. b. Once notified, the daemon calls the kernel back via this netlink service to get the handshake parameters, including an open socket on which to establish the session. c. Once the handshake is complete, the daemon reports the session status and other information via a second netlink operation. This operation marks that it is safe for the kernel to use the open socket and the security session established there. The notification service uses a multicast group. Each handshake mechanism (eg, tlshd) adopts its own group number so that the handshake services are completely independent of one another. The kernel can then tell via netlink_has_listeners() whether a handshake service is active and prepared to handle a handshake request. A new netlink operation, ACCEPT, acts like accept(2) in that it instantiates a file descriptor in the user space daemon's fd table. If this operation is successful, the reply carries the fd number, which can be treated as an open and ready file descriptor. While user space is performing the handshake, the kernel keeps its muddy paws off the open socket. A second new netlink operation, DONE, indicates that the user space daemon is finished with the socket and it is safe for the kernel to use again. The operation also indicates whether a session was established successfully. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2023-04-19net: dsa: mt7530: fix support for MT7531BEDaniel Golle
There are two variants of the MT7531 switch IC which got different features (and pins) regarding port 5: * MT7531AE: SGMII/1000Base-X/2500Base-X SerDes PCS * MT7531BE: RGMII Moving the creation of the SerDes PCS from mt753x_setup to mt7530_probe with commit 6de285229773 ("net: dsa: mt7530: move SGMII PCS creation to mt7530_probe function") works fine for MT7531AE which got two instances of mtk-pcs-lynxi, however, MT7531BE requires mt7531_pll_setup to setup clocks before the single PCS on port 6 (usually used as CPU port) starts to work and hence the PCS creation failed on MT7531BE. Fix this by introducing a pointer to mt7531_create_sgmii function in struct mt7530_priv and call it again at the end of mt753x_setup like it was before commit 6de285229773 ("net: dsa: mt7530: move SGMII PCS creation to mt7530_probe function").

2023-04-19rpmsg: glink: Propagate TX failures in intentless mode as wellBjorn Andersson
As support for splitting transmission over several messages using TX_DATA_CONT was introduced it does not immediately return the return value of qcom_glink_tx(). The result is that in the intentless case (i.e. intent == NULL), the code will continue to send all additional chunks. This is wasteful, and it's possible that the send operation could incorrectly indicate success, if the last chunk fits in the TX fifo. Fix the condition.

2023-04-19rpmsg: glink: Wait for intent, not just request ackBjorn Andersson
In some implementations of the remote firmware, an intent request acknowledgment is sent when it's determined if the intent allocation will be fulfilled, but then the intent is queued after the acknowledgment. The result is that upon receiving a granted allocation request, the search for the newly allocated intent will fail and an additional request will be made. This will at best waste memory, but if the second request is rejected the transaction will be incorrectly rejected. Take the incoming intent into account in the wait to mitigate this problem. The above scenario can still happen, in the case that, on that same channel, an unrelated intent is delivered prior to the request acknowledgment and a separate process enters the send path and picks up the intent. Given that there's no relationship between the acknowledgment and the delivered (or to be delivered intent), there doesn't seem to be a solution to this problem.
