We forgot to do this for the ->get_direction() callback, which means we can sometimes [1] get incorrect results [2] from, e.g., /sys/kernel/debug/gpio. Enable the clock, so we get the right results! [1] Sometimes, because many systems have 1 or mor interrupt requested on each GPIO bank, so they always leave their clock on.

Patch "pinctrl: Really force states during suspend/resume" has been added to the 4.9-stable tree

This is a note to let you know that I've just added the patch titled pinctrl: Really force states during suspend/resume to the 4.9-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: pinctrl-really-force-states-during-suspend-resume.patch and it can be found in the queue-4.9 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 foo@baz Thu Mar 22 14:40:24 CET 2018 From: Florian Fainelli <f.fainelli(a)gmail.com> Date: Wed, 1 Mar 2017 10:32:57 -0800 Subject: pinctrl: Really force states during suspend/resume From: Florian Fainelli <f.fainelli(a)gmail.com> [ Upstream commit 981ed1bfbc6c4660b2ddaa8392893e20a6255048 ] In case a platform only defaults a "default" set of pins, but not a "sleep" set of pins, and this particular platform suspends and resumes in a way that the pin states are not preserved by the hardware, when we resume, we would call pinctrl_single_resume() -> pinctrl_force_default() -> pinctrl_select_state() and the first thing we do is check that the pins state is the same as before, and do nothing. In order to fix this, decouple the actual state change from pinctrl_select_state() and move it pinctrl_commit_state(), while keeping the p->state == state check in pinctrl_select_state() not to change the caller assumptions. pinctrl_force_sleep() and pinctrl_force_default() are updated to bypass the state check by calling pinctrl_commit_state(). [Linus Walleij] The forced pin control states are currently only used in some pin controller drivers that grab their own reference to their own pins. This is equal to the pin control hogs: pins taken by pin control devices since there are no corresponding device in the Linux device hierarchy, such as memory controller lines or unused GPIO lines, or GPIO lines that are used orthogonally from the GPIO subsystem but pincontrol-wise managed as hogs (non-strict mode, allowing simultaneous use by GPIO and pin control). For this case forcing the state from the drivers' suspend()/resume() callbacks makes sense and should semantically match the name of the function.

From: Jarno Rajahalme <jarno(a)ovn.org> [ Upstream commit cf5d70918877c6a6655dc1e92e2ebb661ce904fd ] Conntrack helpers do not check for a potentially clashing conntrack entry when creating a new expectation. Also, nf_conntrack_in() will check expectations (via init_conntrack()) only if a conntrack entry can not be found. The expectation for a packet which also matches an existing conntrack entry will not be removed by conntrack, and is currently handled inconsistently by OVS, as OVS expects the expectation to be removed when the connection tracking entry matching that expectation is confirmed. It should be noted that normally an IP stack would not allow reuse of a 5-tuple of an old (possibly lingering) connection for a new data connection, so this is somewhat unlikely corner case. However, it is possible that a misbehaving source could cause conntrack entries be created that could then interfere with new related connections. Fix this in the OVS module by deleting the clashing conntrack entry after an expectation has been matched. This causes the following nf_conntrack_in() call also find the expectation and remove it when creating the new conntrack entry, as well as the forthcoming reply direction packets to match the new related connection instead of the old clashing conntrack entry.

The result is that for layouts that have more than one layout segment per file, the pg_lseg is not cleared, so we can end up hitting the WARN_ON_ONCE(req_start >= seg_end) in pnfs_generic_pg_test since the pg_lseg will be pointing to that previously-flushed layout segment.

From: NeilBrown <neilb(a)suse.com> [ Upstream commit 99bbf6ecc694dfe0b026e15359c5aa2a60b97a93 ] consider the sequence of commands: mkdir -p /import/nfs /import/bind /import/etc mount --bind / /import/bind mount --make-private /import/bind mount --bind /import/etc /import/bind/etc exportfs -o rw,no_root_squash,crossmnt,async,no_subtree_check localhost:/ mount -o vers=4 localhost:/ /import/nfs ls -l /import/nfs/etc You would not expect this to report a stale file handle. Yet it does. The manipulations under /import/bind cause the dentry for /etc to get the DCACHE_MOUNTED flag set, even though nothing is mounted on /etc. This causes nfsd to call nfsd_cross_mnt() even though there is no mountpoint. So an upcall to mountd for "/etc" is performed. The 'crossmnt' flag on the export of / causes mountd to report that /etc is exported as it is a descendant of /. It assumes the kernel wouldn't ask about something that wasn't a mountpoint. The filehandle returned identifies the filesystem and the inode number of /etc. When this filehandle is presented to rpc.mountd, via "nfsd.fh", the inode cannot be found associated with any name in /etc/exports, or with any mountpoint listed by getmntent(). So rpc.mountd says the filehandle doesn't exist. Hence ESTALE. This is fixed by teaching nfsd not to trust DCACHE_MOUNTED too much. It is just a hint, not a guarantee. Change nfsd_mountpoint() to return '1' for a certain mountpoint, '2' for a possible mountpoint, and 0 otherwise. Then change nfsd_crossmnt() to check if follow_down() actually found a mountpount and, if not, to avoid performing a lookup if the location is not known to certainly require an export-point.

Patch "netfilter: nf_ct_helper: permit cthelpers with different names via nfnetlink" has been added to the 4.9-stable tree

So even with the different names, we will also fail to add them: # nfct helper add ssdp inet udp # nfct helper add tftp inet udp nfct v1.4.3: netlink error: File exists So in order to avoid unpredictable behaviour, we should: 1. cthelpers can be selected by nft ct helper obj or xt_CT target, so report error if duplicated { name, l3proto, l4proto } tuple exist. 2. cthelpers can be selected by nf_ct_tuple_src_mask_cmp when nf_ct_auto_assign_helper is enabled, so also report error if duplicated { l3proto, l4proto, src-port } tuple exist. Also note, if the cthelper is added from userspace, then the src-port will always be zero, it's invalid for nf_ct_auto_assign_helper, so there's no need to check the second point listed above.

After suspend/resume, the wifi and bluetooth interfaces disappear and do not get probed again. The conditions here are: 1. During suspend, we reach mmc_pm_notify() 2. mmc_pm_notify() calls mmc_sdio_pre_suspend() to see if we can suspend the SDIO host. However, mmc_sdio_pre_suspend() returns -ENOSYS because btsdio_driver does not have a suspend method. 3. mmc_pm_notify() proceeds to remove the card 4. Upon resume, mmc_rescan() does nothing with this host, because of the rescan_entered check which aims to only scan a non-removable device a single time (i.e. during boot). Fix the loss of functionality by detecting that we are unable to suspend a non-removable host, so avoid the forced removal in that case. The comment above this function already indicates that this code was only intended for removable devices.
