[ Upstream commit aeabb3c9 ] Fix a deadlock whereby the NFSv4 state manager can get stuck in the delegation return code, waiting for a layout return to complete in another thread. If the server reboots before that other thread completes, then we need to be able to start a second state manager thread in order to perform recovery. Signed-off-by:

[ Upstream commit e76ad21d ] During resume from hibernation if ena_restore_device fails, ena_com_dev_reset() is called, and uses the readless read mechanism, which was already destroyed by the call to ena_com_mmio_reg_read_request_destroy(). This causes a NULL pointer reference. In this commit we switch the call order of the above two functions to avoid this crash.

[ Upstream commit 4d26d1d1 ] This reverts commit 336fd4f5. Please note that `strlcpy()` does *NOT* do what you think it does. strlcpy() *ALWAYS* reads the full input string, regardless of the 'length' parameter. That is, if the input is not zero-terminated, strlcpy() will *READ* beyond input boundaries. It does this, because it always returns the size it *would* copy if the target was big enough, not the truncated size it actually copied. The original code was perfectly fine. The hid device is zero-initialized and the strncpy() functions copied up to n-1 characters. The result is always zero-terminated this way. This is the third time someone tried to replace strncpy with strlcpy in this function, and gets it wrong. I now added a comment that should at least make people reconsider. Signed-off-by:

[ Upstream commit d98ccfc3 ] Currently the ti-cpufreq driver blindly registers a 'ti-cpufreq' to force the driver to probe on any platforms where the driver is built in. However, this should only happen on platforms that actually can make use of the driver. There is already functionality in place to match the SoC compatible so let's factor this out into a separate call and make sure we find a match before creating the ti-cpufreq platform device.

[ Upstream commit 70cdb6ad ] As pointed out by Gregor, spitz keyboard matrix is broken, with or without CONFIG_PINCTRL set, quoting : "The gpio matrix keypard on the Zaurus C3x00 (see spitz.c) does not work properly. Noticeable are that rshift+c does nothing where as lshift+c creates C. Opposite it is for rshift+a vs lshift+a, here only rshift works. This affects a few other combinations using the rshift or lshift buttons." As a matter of fact, as for platform_data based builds CONFIG_PINCTRL=n is required for now (as opposed for devicetree builds where it should be set), this means gpio driver should change the direction, which is what was attempted by commit c4e5ffb6 ("gpio: pxa: fix legacy non pinctrl aware builds"). Unfortunately, the input case was inverted, and the direction change was never done. This wasn't seen up until now because the initial platform setup (MFP) was setting this direction. Yet in Gregory's case, the matrix-keypad driver changes back and forth the direction dynamically, and this is why he's the first to report it.

[ Upstream commit bd85fbc2 ] When re-registering a user mr, the mpt information for the existing mr when running SRIOV is obtained via the QUERY_MPT fw command. The returned information includes the mpt's lkey. This retrieved mpt information is used to move the mpt back to hardware ownership in the rereg flow (via the SW2HW_MPT fw command when running SRIOV). The fw API spec states that for SW2HW_MPT, the lkey field must be zero. Any ConnectX-3 PF driver which checks for strict spec adherence will return failure for SW2HW_MPT if the lkey field is not zero (although the fw in practice ignores this field for SW2HW_MPT). Thus, in order to conform to the fw API spec, set the lkey field to zero before invoking SW2HW_MPT when running SRIOV.

[ Upstream commit 07e3a1cf ] [Why] Many panels support more than 8bpc but some modes are unavailable while running at greater than 8bpc due to DP/HDMI bandwidth constraints. Support for more than 8bpc was added recently in the driver but it defaults to the maximum supported bpc - locking out these modes. This should be a user configurable option such that the user can select what bpc configuration they would like. [How] This patch adds support for getting and setting the amdgpu driver specific "max bpc" property on the connector. It also adds support for limiting the output bpc based on the property value. The default limitation is the lowest value in the range, 8bpc. This was the old value before the range was uncapped. This patch should be updated/replaced later once common drm support for max bpc lands.

[ Upstream commit 4cff280a ] If an io error occurs on an io issued while connecting, recovery of the io falls flat as the state checking ends up nooping the error handler. Create an err_work work item that is scheduled upon an io error while connecting. The work thread terminates all io on all queues and marks the queues as not connected. The termination of the io will return back to the callee, which will then back out of the connection attempt and will reschedule, if possible, the connection attempt. The changes: - in case there are several commands hitting the error handler, a state flag is kept so that the error work is only scheduled once, on the first error. The subsequent errors can be ignored. - The calling sequence to stop keep alive and terminate the queues and their io is lifted from the reset routine. Made a small service routine used by both reset and err_work. - During debugging, found that the teardown path can reference an uninitialized pointer, resulting in a NULL pointer oops. The aen_ops weren't initialized yet. Add validation on their initialization before calling the teardown routine. Signed-off-by:

Otherwise there are small windows possible with missing interrupts for incoming data. SMC-D currently does not care about the old value of the SBA DMBE mask. Acked-by:

[ Upstream commit 291d57f6 ] Certain flows need to access the rdma-info structure, for example dcbx update flows. In some cases there can be a race between the allocation or deallocation of the structure which was done in roce start / roce stop and an asynchrounous dcbx event that tries to access the structure. For this reason, we move the allocation of the rdma_info structure to be similar to the iscsi/fcoe info structures which are allocated during device setup. We add a new field of "active" to the struct to define whether roce has already been started or not, and this is checked instead of whether the pointer to the info structure.

[ Upstream commit 77e461d1 ] Driver assigns DMAE channel 0 for FW as part of START_RAMROD command. FW uses this channel for DMAE operations (e.g., TIME_SYNC implementation). Driver also uses the same channel 0 for DMAE operations for some of the PFs (e.g., PF0 on Port0). This could lead to concurrent access to the DMAE channel by FW and driver which is not legal. Hence need to assign unique DMAE id for FW. Currently following DMAE channels are used by the clients, MFW - OCBB/OCSD functionality uses DMAE channel 14/15 Driver 0-3 and 8-11 (for PF dmae operations) 4 and 12 (for stats requests) Assigning unique dmae_id '13' to the FW.

[ Upstream commit d7d8bbb4 ] The complete size ("total_size") of the fragmented packet is stored in the fragment header and in the size of the fragment chain. When the fragments are ready for merge, the skbuff's tail of the first fragment is expanded to have enough room after the data pointer for at least total_size. This means that it gets expanded by total_size - first_skb->len. But this is ignoring the fact that after expanding the buffer, the fragment header is pulled by from this buffer. Assuming that the tailroom of the buffer was already 0, the buffer after the data pointer of the skbuff is now only total_size - len(fragment_header) large. When the merge function is then processing the remaining fragments, the code to copy the data over to the merged skbuff will cause an skb_over_panic when it tries to actually put enough data to fill the total_size bytes of the packet. The size of the skb_pull must therefore also be taken into account when the buffer's tailroom is expanded. Fixes: 610bfc6b ("batman-adv: Receive fragmented packets and merge") Reported-by:

[ Upstream commit f4156f96 ] The announcement messages of batman-adv COMPAT_VERSION 15 have the possibility to announce additional information via a dynamic TVLV part. This part is optional for the ELP packets and currently not parsed by the Linux implementation. Still out-of-tree versions are using it to transport things like neighbor hashes to optimize the rebroadcast behavior. Since the ELP broadcast packets are smaller than the minimal ethernet packet, it often has to be padded. This is often done (as specified in RFC894) with octets of zero and thus work perfectly fine with the TVLV part (making it a zero length and thus empty). But not all ethernet compatible hardware seems to follow this advice. To avoid ambiguous situations when parsing the TVLV header, just force the 4 bytes (TVLV length + padding) after the required ELP header to zero.

[ Upstream commit 32388d6e ] While there are issues related to object lifetime management, unregister the media device first, followed immediately by other device nodes when the driver is being unbound.
