With a basic Linux userspace, the messages "Calling CRDA to update world regulatory domain" appears 10 times after boot every second or so, followed by a final "Exceeded CRDA call max attempts. Not calling CRDA". For those of us not having the corresponding userspace parts, having those messages repeatedly displayed at boot time is a bit annoying, so this commit reduces their log level to pr_debug().

If the hardware is unregistered while interfaces are up, mac80211 will unregister all interfaces, which in turns causes mac80211 to be called again to remove them all from the driver and eventually shut down the hardware. During this shutdown, however, it's currently already unsafe to iterate the list of interfaces atomically, as the list is manipulated in an unsafe manner. This puts an undue burden on the driver - it must stop all its activities before calling ieee80211_unregister_hw(), while in the normal stop path it can do all cleanup in the stop method. If, for example, it's using the iteration during RX for some reason, it would have to stop RX before unregistering to avoid crashes. Fix this problem by closing all interfaces before unregistering them. This will cause the driver stop to have completed before we manipulate the interface list, and after the driver is stopped *and* has called ieee80211_unregister_hw() it really musn't be iterating any more as the memory will be freed as well.

If for any reason we're in the middle of PS-polling or awake after TX due to dynamic powersave while going to suspend, go back to save power. This might cause a response frame to get lost, but since we can't really wait for it while going to suspend that's still better than not enabling powersave which would cause higher power usage during (and possibly even after) suspend. Note that this really only affects the very few drivers that use the powersave implementation in mac80211.

When acting as AP and a PS-Poll frame is received associated station is marked as one in a Service Period. This state is kept until Tx status for released frame is reported. While a station is in Service Period PS-Poll frames are ignored. However if PS-Poll was received during A-MPDU teardown it was possible to have the to-be released frame re-queued back to pending queue. In such case the frame was stripped of 2 important flags: (a) IEEE80211_TX_CTL_NO_PS_BUFFER (b) IEEE80211_TX_STATUS_EOSP Stripping of (a) led to the frame that was to be released to be queued back to ps_tx_buf queue. If station remained to use only PS-Poll frames the re-queued frame (and new ones) was never actually transmitted because mac80211 would ignore subsequent PS-Poll frames due to station being in Service Period. There was nothing left to clear the Service Period bit (no xmit -> no tx status -> no SP end), i.e. the AP would have the station stuck in Service Period. Beacon TIM would repeatedly prompt station to poll for frames but it would get none. Once (a) is not stripped (b) becomes important because it's the main condition to clear the Service Period bit of the station when Tx status for the released frame is reported back. This problem was observed with ath9k acting as P2P GO in some testing scenarios but isn't limited to it. AP operation with mac80211 based Tx A-MPDU control combined with clients using PS-Poll frames is subject to this race.

This reverts commit dec4f799. Jörg Otte reports a NULL pointder dereference due to this commit, as 'crtc_state' very much can be NULL: crtc_state = state->base.state ? intel_atomic_get_crtc_state(state->base.state, intel_crtc) : NULL; So the change to test 'crtc_state->base.active' cannot possibly be correct as-is. There may be some other minimal fix (like just checking crtc_state for NULL), but I'm just reverting it now for the rc2 release, and people like Daniel Vetter who actually know this code will figure out what the right solution is in the longer term.

Commit 514ac99c "can: fix multiple delivery of a single CAN frame for overlapping CAN filters" requires the skb->tstamp to be set to check for identical CAN skbs. Without timestamping to be required by user space applications this timestamp was not generated which lead to commit 36c01245 "can: fix loss of CAN frames in raw_rcv" - which forces the timestamp to be set in all CAN related skbuffs by introducing several __net_timestamp() calls. This forces e.g. out of tree drivers which are not using alloc_can{,fd}_skb() to add __net_timestamp() after skbuff creation to prevent the frame loss fixed in mainline Linux. This patch removes the timestamp dependency and uses an atomic counter to create an unique identifier together with the skbuff pointer. Btw: the new skbcnt element introduced in struct can_skb_priv has to be initialized with zero in out-of-tree drivers which are not using alloc_can{,fd}_skb() too.

Driver core sets "default" pinmux on on probe and CAN driver sets "sleep" pinmux during register. This causes a small window where the CAN pins are in "default" state with the DCAN module being disabled. Change the "default" state to be like sleep so this glitch is avoided. Add a new "active" state that is used by the driver when CAN is actually active.

J.D. Schroeder authored
The previous change 3973c526 (net: can: c_can: Disable pins when CAN interface is down) causes a slight glitch on the pinctrl settings when used. Since commit ab78029e (drivers/pinctrl: grab default handles from device core), the device core will automatically set the default pins. This causes the pins to be momentarily set to the default and then to the sleep state in register_c_can_dev(). By adding an optional "enable" state, boards can set the default pin state to be disabled and avoid the glitch when the switch from default to sleep first occurs. If the "enable" state is not available c_can_pinctrl_select_state() falls back to using the "default" pinctrl state. [Roger Q] - Forward port to v4.2 and use pinctrl_get_select(). Signed-off-by: J.D.

rcar_can_probe() regards 0 as a wrong IRQ #, despite platform_get_irq() that it calls returns negative error code in that case. This leads to the following being printed to the console when attempting to open the device: error requesting interrupt fffffffa because rcar_can_open() calls request_irq() with a negative IRQ #, and that function naturally fails with -EINVAL.

Normally opening a file, unlinking it and then closing will have the inode freed upon close() (provided that it's not otherwise busy and has no remaining links, of course). However, there's one case where that does *not* happen. Namely, if you open it by fhandle with cold dcache, then unlink() and close(). In normal case you get d_delete() in unlink(2) notice that dentry is busy and unhash it; on the final dput() it will be forcibly evicted from dcache, triggering iput() and inode removal. In this case, though, we end up with *two* dentries - disconnected (created by open-by-fhandle) and regular one (used by unlink()). The latter will have its reference to inode dropped just fine, but the former will not - it's considered hashed (it is on the ->s_anon list), so it will stay around until the memory pressure will finally do it in. As the result, we have the final iput() delayed indefinitely. It's trivial to reproduce - void flush_dcache(void) { system("mount -o remount,rw /"); } static char buf[20 * 1024 * 1024]; main() { int fd; union { struct file_handle f; char buf[MAX_HANDLE_SZ]; } x; int m; x.f.handle_bytes = sizeof(x); chdir("/root"); mkdir("foo", 0700); fd = open("foo/bar", O_CREAT | O_RDWR, 0600); close(fd); name_to_handle_at(AT_FDCWD, "foo/bar", &x.f, &m, 0); flush_dcache(); fd = open_by_handle_at(AT_FDCWD, &x.f, O_RDWR); unlink("foo/bar"); write(fd, buf, sizeof(buf)); system("df ."); /* 20Mb eaten */ close(fd); system("df ."); /* should've freed those 20Mb */ flush_dcache(); system("df ."); /* should be the same as #2 */ } will spit out something like Filesystem 1K-blocks Used Available Use% Mounted on /dev/root 322023 303843 1131 100% / Filesystem 1K-blocks Used Available Use% Mounted on /dev/root 322023 303843 1131 100% / Filesystem 1K-blocks Used Available Use% Mounted on /dev/root 322023 283282 21692 93% / - inode gets freed only when dentry is finally evicted (here we trigger than by remount; normally it would've happened in response to memory pressure hell knows when).

Now that those apis are merged we implement them in the BLK driver to guarantee that mmio aperture moves stay ordered with respect to incoming read/write requests, and that writes are flushed through those mmio-windows and platform-buffers to be persistent on media.
