2023-09-11cxl/pci: Fix appropriate checking for _OSC while handling CXL RAS registersSmita Koralahalli
cxl_pci fails to unmask CXL protocol errors when CXL memory error reporting is not granted native control. Given that CXL memory error reporting uses the event interface and protocol errors use AER, unmask protocol errors based only on the native AER setting. Without this change end user deployments will fail to report protocol errors in the case where native memory error handling is not granted to Linux. Also, return zero instead of an error code to not block the communication with the cxl device when in native memory error reporting mode.

2023-09-11drm/amd/display: Adjust the MST resume flowWayne Lin
[Why] In drm_dp_mst_topology_mgr_resume() today, it will resume the mst branch to be ready handling mst mode and also consecutively do the mst topology probing. Which will cause the dirver have chance to fire hotplug event before restoring the old state. Then Userspace will react to the hotplug event based on a wrong state. [How] Adjust the mst resume flow as: 1. set dpcd to resume mst branch status 2. restore source old state 3. Do mst resume topology probing For drm_dp_mst_topology_mgr_resume(), it's better to adjust it to pull out topology probing work into a 2nd part procedure of the mst resume. Will have a follow up patch in drm.

2023-09-11clk: si521xx: Fix regmap write accessorMarek Vasut
Rework the write operation such that the Byte Count register is written with a single raw i2c write outside of regmap using transfer which does specify the number of bytes to be transfered, one in this case, and which makes the expected subsequent write transfer look like address+register+data, and then make use of this method. Without this change, the Byte Count register write in probe() would succeed as it would provide the byte count as part of its write payload, but any subsequent writes would fail due to this Byte Count register programming. Such failing writes happens e.g. during resume, when restoring the regmap content.

2023-09-11mtd: rawnand: marvell: Ensure program page operations are successfulMiquel Raynal
The NAND core complies with the ONFI specification, which itself mentions that after any program or erase operation, a status check should be performed to see whether the operation was finished *and* successful. The NAND core offers helpers to finish a page write (sending the "PAGE PROG" command, waiting for the NAND chip to be ready again, and checking the operation status). But in some cases, advanced controller drivers might want to optimize this and craft their own page write helper to leverage additional hardware capabilities, thus not always using the core facilities. Some drivers, like this one, do not use the core helper to finish a page write because the final cycles are automatically managed by the hardware. In this case, the additional care must be taken to manually perform the final status check. Let's read the NAND chip status at the end of the page write helper and return -EIO upon error.

2023-09-11of: dynamic: Fix potential memory leak in of_changeset_action()Dan Carpenter
Smatch complains that the error path where "action" is invalid leaks the "ce" allocation: drivers/of/dynamic.c:935 of_changeset_action() warn: possible memory leak of 'ce' Fix this by doing the validation before the allocation. Note that there is not any actual problem with upstream kernels. All callers of of_changeset_action() are static inlines with fixed action values.

2023-09-11wifi: iwlwifi: mvm: Fix a memory corruption issueChristophe JAILLET
A few lines above, space is kzalloc()'ed for: sizeof(struct iwl_nvm_data) + sizeof(struct ieee80211_channel) + sizeof(struct ieee80211_rate) 'mvm->nvm_data' is a 'struct iwl_nvm_data', so it is fine. At the end of this structure, there is the 'channels' flex array. Each element is of type 'struct ieee80211_channel'. So only 1 element is allocated in this array. When doing: mvm->nvm_data->bands[0].channels = mvm->nvm_data->channels; We point at the first element of the 'channels' flex array. So this is fine. However, when doing: mvm->nvm_data->bands[0].bitrates = (void *)((u8 *)mvm->nvm_data->channels + 1); because of the "(u8 *)" cast, we add only 1 to the address of the beginning of the flex array. It is likely that we want point at the 'struct ieee80211_rate' allocated just after. Remove the spurious casting so that the pointer arithmetic works as expected.

The iwl_fw_ini_error_dump_range structure has conflicting alignment requirements for the inner union and the outer struct: In file included from drivers/net/wireless/intel/iwlwifi/fw/dbg.c:9: drivers/net/wireless/intel/iwlwifi/fw/error-dump.h:312:2: error: field within 'struct iwl_fw_ini_error_dump_range' is less aligned than 'union iwl_fw_ini_error_dump_range::(anonymous at drivers/net/wireless/intel/iwlwifi/fw/error-dump.h:312:2)' and is usually due to 'struct iwl_fw_ini_error_dump_range' being packed, which can lead to unaligned accesses [-Werror,-Wunaligned-access] union { As the original intention was apparently to make the entire structure unaligned, mark the innermost members the same way so the union becomes packed as well.

2023-09-11RDMA/siw: Fix connection failure handlingBernard Metzler
In case immediate MPA request processing fails, the newly created endpoint unlinks the listening endpoint and is ready to be dropped. This special case was not handled correctly by the code handling the later TCP socket close, causing a NULL dereference crash in siw_cm_work_handler() when dereferencing a NULL listener. We now also cancel the useless MPA timeout, if immediate MPA request processing fails. This patch furthermore simplifies MPA processing in general: Scheduling a useless TCP socket read in sk_data_ready() upcall is now surpressed, if the socket is already moved out of TCP_ESTABLISHED state.

2023-09-11RDMA/srp: Do not call scsi_done() from srp_abort()Bart Van Assche
After scmd_eh_abort_handler() has called the SCSI LLD eh_abort_handler callback, it performs one of the following actions: * Call scsi_queue_insert(). * Call scsi_finish_command(). * Call scsi_eh_scmd_add(). Hence, SCSI abort handlers must not call scsi_done(). Otherwise all the above actions would trigger a use-after-free. Hence remove the scsi_done() call from srp_abort(). Keep the srp_free_req() call before returning SUCCESS because we may not see the command again if SUCCESS is returned.

Add a "disable" event with event_number 0 for all blocks. - The enable bit for each counter need not be checked before reading the event info, and hence removed.
