IB/mlx5: Replace tunnel mpls capability bits for tunnel_offloads

2020-04-13T11:16:41Z

commit 41e684ef3f37ce6e5eac3fb5b9c7c1853f4b0447 upstream. Until now the flex parser capability was used in ib_query_device() to indicate tunnel_offloads_caps support for mpls_over_gre/mpls_over_udp. Newer devices and firmware will have configurations with the flexparser but without mpls support. Testing for the flex parser capability was a mistake, the tunnel_stateless capability was intended for detecting mpls and was introduced at the same time as the flex parser capability. Otherwise userspace will be incorrectly informed that a future device supports MPLS when it does not.

ACPI: PM: Add acpi_[un]register_wakeup_handler()

2020-04-13T11:16:39Z

commit ddfd9dcf270ce23ed1985b66fcfa163920e2e1b8 upstream. Since commit fdde0ff8590b ("ACPI: PM: s2idle: Prevent spurious SCIs from waking up the system") the SCI triggering without there being a wakeup cause recognized by the ACPI sleep code will no longer wakeup the system. This works as intended, but this is a problem for devices where the SCI is shared with another device which is also a wakeup source. In the past these, from the pov of the ACPI sleep code, spurious SCIs would still cause a wakeup so the wakeup from the device sharing the interrupt would actually wakeup the system. This now no longer works. This is a problem on e.g. Bay Trail-T and Cherry Trail devices where some peripherals (typically the XHCI controller) can signal a Power Management Event (PME) to the Power Management Controller (PMC) to wakeup the system, this uses the same interrupt as the SCI. These wakeups are handled through a special INT0002 ACPI device which checks for events in the GPE0a_STS for this and takes care of acking the PME so that the shared interrupt stops triggering. The change to the ACPI sleep code to ignore the spurious SCI, causes the system to no longer wakeup on these PME events. To make things worse this means that the INT0002 device driver interrupt handler will no longer run, causing the PME to not get cleared and resulting in the system hanging. Trying to wakeup the system after such a PME through e.g. the power button no longer works. Add an acpi_register_wakeup_handler() function which registers a handler to be called from acpi_s2idle_wake() and when the handler returns true, return true from acpi_s2idle_wake(). The INT0002 driver will use this mechanism to check the GPE0a_STS register from acpi_s2idle_wake() and to tell the system to wakeup if a PME is signaled in the register.

include/uapi/linux/swab.h: fix userspace breakage, use __BITS_PER_LONG for swap

commit 467d12f5c7842896d2de3ced74e4147ee29e97c8 upstream. QEMU has a funny new build error message when I use the upstream kernel headers: CC block/file-posix.o In file included from /home/cborntra/REPOS/qemu/include/qemu/timer.h:4, from /home/cborntra/REPOS/qemu/include/qemu/timed-average.h:29, from /home/cborntra/REPOS/qemu/include/block/accounting.h:28, from /home/cborntra/REPOS/qemu/include/block/block_int.h:27, from /home/cborntra/REPOS/qemu/block/file-posix.c:30: /usr/include/linux/swab.h: In function `__swab': /home/cborntra/REPOS/qemu/include/qemu/bitops.h:20:34: error: "sizeof" is not defined, evaluates to 0 [-Werror=undef] 20 | #define BITS_PER_LONG (sizeof (unsigned long) * BITS_PER_BYTE) | ^~~~~~ /home/cborntra/REPOS/qemu/include/qemu/bitops.h:20:41: error: missing binary operator before token "(" 20 | #define BITS_PER_LONG (sizeof (unsigned long) * BITS_PER_BYTE) | ^ cc1: all warnings being treated as errors make: *** [/home/cborntra/REPOS/qemu/rules.mak:69: block/file-posix.o] Error 1 rm tests/qemu-iotests/socket_scm_helper.o This was triggered by commit d5767057c9a ("uapi: rename ext2_swab() to swab() and share globally in swab.h").

uapi: rename ext2_swab() to swab() and share globally in swab.h

2020-04-13T11:16:34Z

commit d5767057c9a76a29f073dad66b7fa12a90e8c748 upstream. ext2_swab() is defined locally in lib/find_bit.c However it is not specific to ext2, neither to bitmaps. There are many potential users of it, so rename it to just swab() and move to include/uapi/linux/swab.h ABI guarantees that size of unsigned long corresponds to BITS_PER_LONG, therefore drop unneeded cast.

libceph: fix alloc_msg_with_page_vector() memory leaks

2020-04-02T13:09:53Z

commit e886274031200bb60965c1b9c49b7acda56a93bd upstream. Make it so that CEPH_MSG_DATA_PAGES data item can own pages, fixing a bunch of memory leaks for a page vector allocated in alloc_msg_with_page_vector(). Currently, only watch-notify messages trigger this allocation, and normally the page vector is freed either in handle_watch_notify() or by the caller of ceph_osdc_notify(). But if the message is freed before that (e.g. if the session faults while reading in the message or if the notify is stale), we leak the page vector. This was supposed to be fixed by switching to a message-owned pagelist, but that never happened.
