Fix the firmware selection by adding files for the B-steps; add configuration for some integrated devices; and add a bunch of PCI IDs (mostly for integrated devices) that were missing from the driver's list. Without this patch, a lot of devices will not be recognized or will try to load the wrong firmware file.

[Linux-stable-mirror] Patch "iwlwifi: pcie: sort IDs for the 9000 series for easier comparisons" has been added to the 4.14-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled iwlwifi: pcie: sort IDs for the 9000 series for easier comparisons to the 4.14-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: iwlwifi-pcie-sort-ids-for-the-9000-series-for-easier-comparisons.patch and it can be found in the queue-4.14 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From 1105a337375258515ed09b92a83fd7bfd6775958 Mon Sep 17 00:00:00 2001 From: Luca Coelho <luciano.coelho(a)intel.com> Date: Thu, 12 Oct 2017 11:20:50 +0300 Subject: iwlwifi: pcie: sort IDs for the 9000 series for easier comparisons From: Luca Coelho <luciano.coelho(a)intel.com> commit 1105a337375258515ed09b92a83fd7bfd6775958 upstream. It's hard to find values that are missing in the list, so sorting the values and comparing them makes it much easier. To simplify this task, sort the devices in the list.

Newer firmware versions (such as iwlwifi-8000C-34.ucode) have introduced an API change in the SCAN_REQ_UMAC command that is not backwards compatible. The driver needs to detect and use the new API format when the firmware reports it, otherwise the scan command will not work properly, causing a command timeout. Fix this by adding a TLV that tells the driver that the new API is in use and use the correct structures for it.

[Linux-stable-mirror] Patch "iwlwifi: fix PCI IDs and configuration mapping for 9000 series" has been added to the 4.14-stable tree

A lot of PCI IDs were missing and there were some problems with the configuration and firmware selection for devices on the 9000 series. Fix the firmware selection by adding files for the B-steps; add configuration for some integrated devices; and add a bunch of PCI IDs (mostly for integrated devices) that were missing from the driver's list. Without this patch, a lot of devices will not be recognized or will try to load the wrong firmware file.

Re: [Linux-stable-mirror] [PATCH] Ensure that the SCSI error handler gets woken up

by Pavel Tikhomirov

Sorry, missed the thread, resending. 1-st, Stuart - thanks for adding me to CC, 2-nd Bart - no idea why you didn't? =) > If scsi_eh_scmd_add() is called concurrently with scsi_host_queue_ready() > while shost->host_blocked > 0 then it can happen that neither function > wakes up the SCSI error handler. Fix this by making every function that > decreases the host_busy counter to wake up the error handler if necessary. Bart, you've added a comment to my initial patch() about performance, let me quote it here: > An important achievement of the scsi-mq code was removal of all > spin_lock_irq(shost->host_lock) statements from the hot path. The above > changes will have a significant negative performance impact, especially if > multiple LUNs associated with the same SCSI host are involved. Can the > reported race be fixed without slowing down the hot path significantly? I > think that both adding spin lock or smp_mb() calls in the hot path will > have a significant negative performance impact. These was a tricky question so I had no immediate answer. Here is the one: a) We need to check if scsi_eh_wakeup needs to wake up error handler thread in every place where we change host_busy. Else we have a chance that these change will break the wake up check in other existing places and will lead to deadlock. b) If we have several variables and change them (one different variable in in different thread) and after that we want to check the joint state of these variables, we sould surely have some kind of memory barriers to have a consistent state at some point. c) We already have spinlocks in scsi_schedule_eh, scsi_eh_scmd_add and scsi_device_unbusy, so it seems the good thing to reuse them for new checks too. I don't see another way to fix these problem. Your patch puts spinlocks under check which should itself be under spinlock, and breaks the initial fix (see Stuart's comment that the problem still reproduces). And you does _not_ answer your own question. > > Reported-by: Pavel Tikhomirov <ptikhomirov@xxxxxxxxxxxxx> > Fixes: commit 746650160866 ("scsi: convert host_busy to atomic_t") > Signed-off-by: Bart Van Assche <bart.vanassche@xxxxxxx> As your patch is based on my initial patch (https://patchwork.kernel.org/patch/9938919/), when all problems will be resolved with it, can you please add here: Signed-off-by: Pavel Tikhomirov <ptikhomirov(a)virtuozzo.com> > Cc: Konstantin Khorenko <khorenko@xxxxxxxxxxxxx> > Cc: Stuart Hayes <stuart.w.hayes@xxxxxxxxx> > Cc: Christoph Hellwig <hch@xxxxxx> > Cc: Hannes Reinecke <hare@xxxxxxxx> > Cc: Johannes Thumshirn <jthumshirn@xxxxxxx> > Cc: <stable@xxxxxxxxxxxxxxx> > --- > drivers/scsi/scsi_error.c | 3 ++- > drivers/scsi/scsi_lib.c | 22 ++++++++++++++-------- > 2 files changed, 16 insertions(+), 9 deletions(-) > > diff --git a/drivers/scsi/scsi_error.c b/drivers/scsi/scsi_error.c > index 5e89049e9b4e..f7f014c755d7 100644 > --- a/drivers/scsi/scsi_error.c > +++ b/drivers/scsi/scsi_error.c > @@ -61,9 +61,10 @@ static int scsi_eh_try_stu(struct scsi_cmnd *scmd); > static int scsi_try_to_abort_cmd(struct scsi_host_template *, > struct scsi_cmnd *); > > -/* called with shost->host_lock held */ > void scsi_eh_wakeup(struct Scsi_Host *shost) > { > + lockdep_assert_held(shost->host_lock); > + > if (atomic_read(&shost->host_busy) == shost->host_failed) { > trace_scsi_eh_wakeup(shost); > wake_up_process(shost->ehandler); I also think these hunk is just an additional precaution and should be in separate patch. > diff --git a/drivers/scsi/scsi_lib.c b/drivers/scsi/scsi_lib.c > index 1e05e1885ac8..abd37d77af2d 100644 > --- a/drivers/scsi/scsi_lib.c > +++ b/drivers/scsi/scsi_lib.c > @@ -318,22 +318,28 @@ static void scsi_init_cmd_errh(struct scsi_cmnd *cmd) > cmd->cmd_len = scsi_command_size(cmd->cmnd); > } > > -void scsi_device_unbusy(struct scsi_device *sdev) > +static void scsi_dec_host_busy(struct Scsi_Host *shost) > { > - struct Scsi_Host *shost = sdev->host; > - struct scsi_target *starget = scsi_target(sdev); > unsigned long flags; > > atomic_dec(&shost->host_busy); > - if (starget->can_queue > 0) > - atomic_dec(&starget->target_busy); > - > if (unlikely(scsi_host_in_recovery(shost) && > (shost->host_failed || shost->host_eh_scheduled))) { As I've wrote above you do wrong locking here in scsi_dec_host_busy.
