* vfs: do bulk POLL* -> EPOLL* replacementLinus Torvalds2018-02-111-2/+2
| | | | | | | | | | | | | | | | | | | | | | | This is the mindless scripted replacement of kernel use of POLL* variables as described by Al, done by this script: for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'` for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done done with de-mangling cleanups yet to come. NOTE! On almost all architectures, the EPOLL* constants have the same values as the POLL* constants do. But they keyword here is "almost". For various bad reasons they aren't the same, and epoll() doesn't actually work quite correctly in some cases due to this on Sparc et al. The next patch from Al will sort out the final differences, and we should be all done. Scripted-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* rfkill: remove rfkill-regulatorJohannes Berg2017-01-243-166/+0
| | | | | | | | | | | | | There are no users of this ("vrfkill") in the tree, so it's just dead code - remove it. This also isn't really how rfkill is supposed to be used - it's intended as a signalling mechanism to/from the device, which the driver (and partially cfg80211) will handle - having a separate rfkill instance for a regulator is confusing, the driver should use the regulator instead to turn off the device when requested.

* rfkill: Add rfkill-any LED triggerMichał Kępień2017-01-091-1/+71
| | | | | | | | | | | Add a new "global" (i.e. not per-rfkill device) LED trigger, rfkill-any, which may be useful on laptops with a single "radio LED" and multiple radio transmitters. The trigger is meant to turn a LED on whenever there is at least one radio transmitter active and turn it off otherwise.

* Revert "rfkill: Add rfkill-any LED trigger"Johannes Berg2016-12-201-74/+1
| | | | | | | | | | | | | This reverts commit 73f4f76a196d7adb11a1e192bd8024fe0bc83910. As Mike reported, and I should've seen in review, we can't call the new LED functions, which acquire the mutex, from places like rfkill_set_sw_state() that are documented to be callable from any context the user likes to use. For Mike's case it led to a deadlock, but other scenarios are possible. Reported-by: Михаил Кринкин <krinkin.m.u@gmail.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

* rfkill: Add rfkill-any LED triggerMichał Kępień2016-12-131-0/+73
| | | | | | | | | | | | | | | | Add a new "global" (i.e. not per-rfkill device) LED trigger, rfkill-any, which may be useful on laptops with a single "radio LED" and multiple radio transmitters. The trigger is meant to turn a LED on whenever there is at least one radio transmitter active and turn it off otherwise. This requires taking rfkill_global_mutex before calling rfkill_set_block() in rfkill_resume(): since __rfkill_any_led_trigger_event() is called from rfkill_set_block() unconditionally, each caller of the latter needs to take care of locking rfkill_global_mutex.

Since we re-check the list_empty() in a loop after the wait, it's safe to simply use list_empty() without locking. This bug has existed forever, but was only discovered now because all userspace implementations, including the default 'rfkill' tool, use poll() or select() to get a readable fd before attempting to read.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | The driver uses devm_gpiod_get_index(..., index) so that the index refers directly to the GpioIo resource under the ACPI device. The problem with this is that if the ordering changes we get wrong GPIOs. With ACPI 5.1 _DSD we can now use names instead to reference GPIOs analogous to Device Tree. However, we still have systems out there that do not provide _DSD at all. These systems must be supported as well. Luckily we now have acpi_dev_add_driver_gpios() that can be used to provide mappings for systems where _DSD is not provided and still take advantage of _DSD if it exists. This patch changes the driver to create default GPIO mappings if we are running on ACPI system. While there we can drop the indices completely and use devm_gpiod_get() with name instead.

From Ben Hutchings. 5) Add better trace events for debugging driver datapath problems, also from Ben Hutchings. 6) Implement auto corking in TCP, from Eric Dumazet. Basically, if we have a small send and a previous packet is already in the qdisc or device queue, defer until TX completion or we get more data. 7) Allow userspace to manage ipv6 temporary addresses, from Jiri Pirko. 8) Add a qdisc bypass option for AF_PACKET sockets, from Daniel Borkmann. 9) Share IP header compression code between Bluetooth and IEEE802154 layers, from Jukka Rissanen. 10) Fix ipv6 router reachability probing, from Jiri Benc. 11) Allow packets to be captured on macvtap devices, from Vlad Yasevich. 12) Support tunneling in GRO layer, from Jerry Chu. 13) Allow bonding to be configured fully using netlink, from Scott Feldman. 14) Allow AF_PACKET users to obtain the VLAN TPID, just like they can already get the TCI. From Atzm Watanabe. 15) New "Heavy Hitter" qdisc, from Terry Lam. 16) Significantly improve the IPSEC support in pktgen, from Fan Du. 17) Allow ipv4 tunnels to cache routes, just like sockets. From Tom Herbert. 18) Add Proportional Integral Enhanced packet scheduler, from Vijay Subramanian. 19) Allow openvswitch to mmap'd netlink, from Thomas Graf. 20) Key TCP metrics blobs also by source address, not just destination address. From Christoph Paasch. 21) Support 10G in generic phylib. From Andy Fleming. 22) Try to short-circuit GRO flow compares using device provided RX hash, if provided. From Tom Herbert. The wireless and netfilter folks have been busy little bees too. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (2064 commits) net/cxgb4: Fix referencing freed adapter ipv6: reallocate addrconf router for ipv6 address when lo device up fib_frontend: fix possible NULL pointer dereference rtnetlink: remove IFLA_BOND_SLAVE definition rtnetlink: remove check for fill_slave_info in rtnl_have_link_slave_info qlcnic: update version to 5.3.55 qlcnic: Enhance logic to calculate msix vectors. qlcnic: Refactor interrupt coalescing code for all adapters. qlcnic: Update poll controller code path qlcnic: Interrupt code cleanup qlcnic: Enhance Tx timeout debugging. qlcnic: Use bool for rx_mac_learn. bonding: fix u64 division rtnetlink: add missing IFLA_BOND_AD_INFO_UNSPEC sfc: Use the correct maximum TX DMA ring size for SFC9100 Add Shradha Shah as the sfc driver maintainer. net/vxlan: Share RX skb de-marking and checksum checks with ovs tulip: cleanup by using ARRAY_SIZE() ip_tunnel: clear IPCB in ip_tunnel_xmit() in case dst_link_failure() is called net/cxgb4: Don't retrieve stats during recovery ...

| | | | | | | | | | | | | | | | | | | | | | Several files refer to an old address for the Free Software Foundation in the file header comment. Resolve by replacing the address with the URL <http://www.gnu.org/licenses/> so that we do not have to keep updating the header comments anytime the address changes.
