Because thermal_zone_trip_id() does not update the thermal zone object
passed to it, its pointer argument representing the thermal zone can be
const, so adjust its definition accordingly.
No functional impact.

CSR.OPS bits specify the current operating mode and (according to
documentation) they are updated by HW when the operating mode change
request is processed. To comply with this check CSR.OPS before proceeding.
Commit introduces ravb_set_opmode() that does all the necessities for
setting the operating mode (set CCC.OPC (and CCC.GAC, CCC.CSEL, if any) and
wait for CSR.OPS) and call it where needed. This should comply with all the
HW manuals requirements as different manual variants specify that different
modes need to be checked in CSR.OPS when setting CCC.OPC.
If gPTP active in config mode is supported and it needs to be enabled, the
CCC.GAC and CCC.CSEL needs to be configured along with CCC.OPC in the same
write access. For this, ravb_set_opmode() allows passing GAC and CSEL as
part of opmode and the function updates accordingly CCC register.

During QoS scheduling testing with multiple strict priority flows, the
netdev tx watchdog timeout routine is invoked when a low priority QoS
queue doesn't get a chance to transmit the packets because other high
priority flows are completely subscribing the transmit link. The netdev
tx watchdog timeout routine will stop MAC RX and TX functionality in
otx2_stop() routine before cleanup of HW TX queues which results in SMQ
flush errors because the packets belonging to low priority queues will
never gets flushed since MAC TX is disabled. This patch fixes the issue
by re-enabling MAC TX to ensure the packets in HW pipeline gets flushed
properly.

Currently the NIX TX link credits are initialized based on the max frame
size that can be transmitted on a link but when the MTU is changed, the
NIX TX link credits are reprogrammed by the SW based on the new MTU value.
Since SMQ max packet length is programmed to max frame size by default,
there is a chance that NIX TX may stall while sending a max frame sized
packet on the link with insufficient credits to send the packet all at
once. This patch avoids stall issue by not changing the link credits
dynamically when the MTU is changed.

When running the instruction decoder selftest with LLVM=1 and
CONFIG_PVH=y, there is a series of warnings:
arch/x86/tools/insn_decoder_test: warning: Found an x86 instruction decoder bug, please report this.
arch/x86/tools/insn_decoder_test: warning: ffffffff81000050 ea <unknown>
arch/x86/tools/insn_decoder_test: warning: objdump says 1 bytes, but insn_get_length() says 7
arch/x86/tools/insn_decoder_test: warning: Decoded and checked 7214721 instructions with 1 failures
GNU objdump outputs "(bad)" instead of "<unknown>", which is already
handled in the bad_expr regex, so there is no warning.
$ objdump -d arch/x86/platform/pvh/head.o | grep -E '50:\s+ea'
50: ea (bad)
$ llvm-objdump -d arch/x86/platform/pvh/head.o | grep -E '50:\s+ea'
50: ea <unknown>
Add "<unknown>" to the bad_expr regex to clear up the warning, allowing
the instruction decoder selftest to fully pass with llvm-objdump.

kprobe_emulate_call_indirect
kprobe_emulate_call_indirect currently uses int3_emulate_call to emulate
indirect calls. However, int3_emulate_call always assumes the size of
the call to be 5 bytes when calculating the return address. This is
incorrect for register-based indirect calls in x86, which can be either
2 or 3 bytes depending on whether REX prefix is used. At kprobe runtime,
the incorrect return address causes control flow to land onto the wrong
place after return -- possibly not a valid instruction boundary. This
can lead to a panic like the following:

The relevant assembly code is (from objdump, faulting address
highlighted):
ffffffff8102ed9d: 41 ff d3 call *%r11
ffffffff8102eda0: 65 48 <8b> 05 30 c7 ff mov %gs:0x7effc730(%rip),%rax
The emulation incorrectly sets the return address to be ffffffff8102ed9d
+ 0x5 = ffffffff8102eda2, which is the 8b byte in the middle of the next
mov. This in turn causes incorrect subsequent instruction decoding and
eventually triggers the page fault above.
Instead of invoking int3_emulate_call, perform push and jmp emulation
directly in kprobe_emulate_call_indirect. At this point we can obtain
the instruction size from p->ainsn.size so that we can calculate the
correct return address.

A crash was found when dumping SMC-R connections. It can be reproduced
by following steps:
- environment: two RNICs on both sides.
- run SMC-R between two sides, now a SMC_LGR_SYMMETRIC type link group
will be created.
- set the first RNIC down on either side and link group will turn to
SMC_LGR_ASYMMETRIC_LOCAL then.
- run 'smcss -R' and the crash will be triggered.

When the first RNIC is set down, the lgr->lnk[0] will be cleared and an

For rq, we have three cases getting buffers from virtio core:
1. virtqueue_get_buf{,_ctx}
2. virtqueue_detach_unused_buf
3. callback for virtqueue_resize
But in commit 295525e29a5b("virtio_net: merge dma operations when
filling mergeable buffers"), I missed the dma unmap for the #3 case.
That will leak some memory, because I did not release the pages referred
by the unused buffers.
If we do such script, we will make the system OOM.

apparmor: Fix move_mount mediation by detecting if source is detached
|
|
Prevent move_mount from applying the attach_disconnected flag
to move_mount(). This prevents detached mounts from appearing
as / when applying mount mediation, which is not only incorrect
but could result in bad policy being generated.
Basic mount rules like
allow mount,
allow mount options=(move) -> /target/,
will allow detached mounts, allowing older policy to continue
to function. New policy gains the ability to specify `detached` as
a source option
allow mount detached -> /target/,
In addition make sure support of move_mount is advertised as
a feature to userspace so that applications that generate policy
can respond to the addition.
Note: this fixes mediation of move_mount when a detached mount is used,
it does not fix the broader regression of apparmor mediation of
mounts under the new mount api.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing fixes from Steven Rostedt:
- Fix a NULL kernel dereference in set_gid() on tracefs mounting.
When tracefs is mounted with "gid=1000", it will update the existing
dentries to have the new gid. The tracefs_inode which is retrieved by
a container_of(dentry->d_inode) has flags to see if the inode belongs
to the eventfs system.
The issue that was fixed was if getdents() was called on tracefs that
was previously mounted, and was not closed. It will leave a "cursor
dentry" in the subdirs list of the current dentries that set_gid()
walks. On a remount of tracefs, the container_of(dentry->d_inode)
will dereference a NULL pointer and cause a crash when referenced.
Simply have a check for dentry->d_inode to see if it is NULL and if
so, skip that entry.
- Fix the bits of the eventfs_inode structure.
The "is_events" bit was taken from the nr_entries field, but the
nr_entries field wasn't updated to be 30 bits and was still 31.
Including the "is_freed" bit this would use 33 bits which would make
the structure use another integer for just one bit.

According to the Intel Software Manual for I225, Section 7.5.2.7,
hicredit should be multiplied by the constant link-rate value, 0x7736.
Currently, the old constant link-rate value, 0x7735, from the boards
supported on igb are being used, most likely due to a copy'n'paste, as
the rest of the logic is the same for both drivers.
Update hicredit accordingly.

During a PCI FLR the MSI-X Enable flag in the VF PCI MSI-X capability
register will be cleared. This can lead to issues when a VF is
assigned to a VM because in these cases the VF driver receives no
indication of the PF PCI error/reset and additionally it is incapable
of restoring the cleared flag in the hypervisor configuration space
without fully reinitializing the driver interrupt functionality.
Since the VF driver is unable to easily resolve this condition on its own,
restore the VF MSI-X flag during the PF PCI reset handling.
