Both bareudp_xmit_skb() and bareudp6_xmit_skb() read their skb's inner IP header to get its ECN value (with ip_tunnel_ecn_encap()).

The benefit is that events of interest are still logged and the entire trace buffer is not dumped with extraneous logging information when using default lpfc_log_verbose driver parameter settings. Also, delete the keyword "fail" from such log messages as they aren't really causes for concern. The log messages are more for warnings to a SAN admin about SAN activity.

2024-09-12scsi: lpfc: Fix kref imbalance on fabric ndlps from dev_loss_tmo handlerJustin Tee
With a FLOGI outstanding and loss of physical link connection to the fabric for the duration of dev_loss_tmo, there is a fabric ndlp kref imbalance that decrements the kref and sets the NLP_IN_RECOV_POST_DEV_LOSS flag at the same time. The issue is that when the FLOGI completion routine executes, the fabric ndlp could already be freed because of the final kref put from the dev_loss_tmo handler. Fix by early returning before the ndlp kref put if the ndlp is deemed a candidate for NLP_IN_RECOV_POST_DEV_LOSS in the FLOGI completion routine.

During HBA stress testing, a spam of received PLOGIs exposes a resource recovery bug causing leakage of lpfc_sqlq entries from the global phba->sli4_hba.lpfc_els_sgl_list. The issue is in lpfc_els_flush_cmd(), where the driver attempts to recover outstanding ELS sgls when walking the txcmplq. Only CMD_ELS_REQUEST64_CRs and CMD_GEN_REQUEST64_CRs are added to the abort and cancel lists. A check for CMD_XMIT_ELS_RSP64_WQE is missing in order to recover LS_ACC usages of the phba->sli4_hba.lpfc_els_sgl_list too. Fix by adding CMD_XMIT_ELS_RSP64_WQE as part of the txcmplq walk when adding WQEs to the abort and cancel list in lpfc_els_flush_cmd(). Also, update naming convention from CRs to WQEs.

During controller transitioning to READY state, if the controller is found in transient states ("becoming ready" or "reset requested"), driver waits for 510 secs even if the controller transitions out of these states early. This causes an unnecessary delay of 510 secs in the overall firmware initialization sequence. Poll the controller state periodically (every 100 milliseconds) while waiting for the controller to come out of the mentioned transient states. Once the controller transits out of the transient states, come out of the wait loop.

2024-09-12scsi: sd: Fix off-by-one error in sd_read_block_characteristics()Martin Wilck
Ff the device returns page 0xb1 with length 8 (happens with qemu v2.x, for example), sd_read_block_characteristics() may attempt an out-of-bounds memory access when accessing the zoned field at offset 8.

2024-09-12scsi: scsi_debug: Remove a useless memset()Christophe JAILLET
'arr' is kzalloc()'ed, so there is no need to call memset(.., 0, ...) on it. It is already cleared.

2024-09-12scsi: pmcraid: Convert comma to semicolonChen Ni
Replace comma between expressions with semicolons. Using a ',' in place of a ';' can have unintended side effects. Although that is not the case here, it is seems best to use ';' unless ',' is intended. Found by inspection. No functional change intended. Compile tested only.

2024-09-12scsi: sd: Retry START STOP UNIT commandsBart Van Assche
During system resume, sd_start_stop_device() submits a START STOP UNIT command to the SCSI device that is being resumed. That command is not retried in case of a unit attention and hence may fail. An example: [16575.983359] sd 0:0:0:3: [sdd] Starting disk [16575.983693] sd 0:0:0:3: [sdd] Start/Stop Unit failed: Result: hostbyte=0x00 driverbyte=DRIVER_OK [16575.983712] sd 0:0:0:3: [sdd] Sense Key : 0x6 [16575.983730] sd 0:0:0:3: [sdd] ASC=0x29 ASCQ=0x0 [16575.983738] sd 0:0:0:3: PM: dpm_run_callback(): scsi_bus_resume+0x0/0xa0 returns -5 [16575.983783] sd 0:0:0:3: PM: failed to resume async: error -5 Make the SCSI core retry the START STOP UNIT command if the device reports that it has been powered on or that it has been reset.

2024-09-12scsi: mpi3mr: A performance fixTomas Henzl
Commit 0c52310f2600 ("hrtimer: Ignore slack time for RT tasks in schedule_hrtimeout_range()") effectivelly shortens a sleep in a polling function in the driver. That is causing a performance regression as the new value of just 2us is too low, in certain tests the perf drop is ~30%. Fix this by adjusting the sleep to 20us (close to the previous value).
