There are only 4 different definitions between the client and server:
- STATUS_SERVER_UNAVAILABLE: from client/smb2status.h
- STATUS_FILE_NOT_AVAILABLE: from client/smb2status.h
- STATUS_NO_PREAUTH_INTEGRITY_HASH_OVERLAP: from server/smbstatus.h
- STATUS_INVALID_LOCK_RANGE: from server/smbstatus.h
Rename client/smb2status.h to common/smb2status.h, and merge the
2 different definitions of server to common header file.

Pull kvm fix from Paolo Bonzini:
"Do not always honor guest PAT on CPUs that support self-snoop.
This triggers an issue in the bochsdrm driver, which used ioremap()
instead of ioremap_wc() to map the video RAM.
The revert lets video RAM use the WB memory type instead of the slower
UC memory type"
* tag 'for-linus-6.11' of git://git.kernel.org/pub/scm/virt/kvm/kvm:
Revert "KVM: VMX: Always honor guest PAT on CPUs that support self-snoop"
|
|
This reverts commit 377b2f359d1f71c75f8cc352b5c81f2210312d83.
This caused a regression with the bochsdrm driver, which used ioremap()
instead of ioremap_wc() to map the video RAM. After the commit, the
WB memory type is used without the IGNORE_PAT, resulting in the slower
UC memory type. In fact, UC is slow enough to basically cause guests
to not boot... but only on new processors such as Sapphire Rapids and
Cascade Lake. Coffee Lake for example works properly, though that might
also be an effect of being on a larger, more NUMA system.
The driver has been fixed but that does not help older guests. Until we
figure out whether Cascade Lake and newer processors are working as
intended, revert the commit. Long term we might add a quirk, but the
details depend on whether the processors are working as intended: for
example if they are, the quirk might reference bochs-compatible devices,
e.g. in the name and documentation, so that userspace can disable the
quirk by default and only leave it enabled if such a device is being
exposed to the guest.
If instead this is actually a bug in CLX+, then the actions we need to
take are different and depend on the actual cause of the bug.

As Jann points out, PFN mappings are special, because unlike normal
memory mappings, there is no lifetime information associated with the
mapping - it is just a raw mapping of PFNs with no reference counting of
a 'struct page'.
That's all very much intentional, but it does mean that it's easy to
mess up the cleanup in case of errors. Yes, a failed mmap() will always
eventually clean up any partial mappings, but without any explicit
lifetime in the page table mapping itself, it's very easy to do the
error handling in the wrong order.
In particular, it's easy to mistakenly free the physical backing store
before the page tables are actually cleaned up and (temporarily) have
stale dangling PTE entries.
To make this situation less error-prone, just make sure that any partial
pfn mapping is torn down early, before any other error handling.

There is a real deadlock as well as sleeping in atomic() bug in here, if
the bo put happens to be the last ref, since bo destruction wants to
grab the same spinlock and sleeping locks. Fix that by dropping the ref
using xe_bo_put_deferred(), and moving the final commit outside of the
lock. Dropping the lock around the put is tricky since the bo can go
out of scope and delete itself from the list, making it difficult to
navigate to the next list entry.

nf_flow_table_module_init()
Move nf flowtable bpf initialization in nf_flow_table module load
routine since nf_flow_table_bpf is part of nf_flow_table module and not
nf_flow_table_inet one. This patch allows to avoid the following kernel
warning running the reproducer below:

$modprobe nf_flow_table_inet

25216afc9db5 ("PCI: Add managed pcim_intx()") moved the allocation step for
pci_intx()'s device resource from pcim_enable_device() to pcim_intx(). As
before, pcim_enable_device() sets pci_dev.is_managed to true; and it is
never set to false again.
Due to the lifecycle of a struct pci_dev, it can happen that a second
driver obtains the same pci_dev after a first driver ran. If one driver
uses pcim_enable_device() and the other doesn't, this causes the other
driver to run into managed pcim_intx(), which will try to allocate when
called for the first time.
Allocations might sleep, so calling pci_intx() while holding spinlocks
becomes then invalid, which causes lockdep warnings and could cause
deadlocks:
========================================================
WARNING: possible irq lock inversion dependency detected
6.11.0-rc6+ #59 Tainted: G W
--------------------------------------------------------
CPU 0/KVM/1537 just changed the state of lock:
ffffa0f0cff965f0 (&vdev->irqlock){-...}-{2:2}, at:
vfio_intx_handler+0x21/0xd0 [vfio_pci_core] but this lock took another,
HARDIRQ-unsafe lock in the past: (fs_reclaim){+.+.}-{0:0}
and interrupts could create inverse lock ordering between them.
other info that might help us debug this:
Possible interrupt unsafe locking scenario:

lock(fs_reclaim);
<Interrupt>

*** DEADLOCK ***
Have pcim_enable_device()'s release function, pcim_disable_device(), set
pci_dev.is_managed to false so that subsequent drivers using the same
struct pci_dev do not implicitly run into managed code.

With debuging and analysis, worker_thread() accesses to the nullified
worker->pool when the newly created worker is destroyed before being
waken-up, in which case worker_thread() can see the result detach_worker()
reseting worker->pool to NULL at the begining.
Move the code "worker->pool = NULL;" out from detach_worker() to fix the
problem.
worker->pool had been designed to be constant for regular workers and
changeable for rescuer. To share attaching/detaching code for regular
and rescuer workers and to avoid worker->pool being accessed inadvertently
when the worker has been detached, worker->pool is reset to NULL when
detached no matter the worker is rescuer or not.
To maintain worker->pool being reset after detached, move the code
"worker->pool = NULL;" in the worker thread context after detached.
It is either be in the regular worker thread context after PF_WQ_WORKER
is cleared or in rescuer worker thread context with wq_pool_attach_mutex
held. So it is safe to do so.

The referenced commit drops bad input, but has false positives.
Tighten the check to avoid these.
The check detects illegal checksum offload requests, which produce
csum_start/csum_off beyond end of packet after segmentation.
But it is based on two incorrect assumptions:
1. virtio_net_hdr_to_skb with VIRTIO_NET_HDR_GSO_TCP[46] implies GSO.
True in callers that inject into the tx path, such as tap.
But false in callers that inject into rx, like virtio-net.
Here, the flags indicate GRO, and CHECKSUM_UNNECESSARY or
CHECKSUM_NONE without VIRTIO_NET_HDR_F_NEEDS_CSUM is normal.
2. TSO requires checksum offload, i.e., ip_summed == CHECKSUM_PARTIAL.
False, as tcp[46]_gso_segment will fix up csum_start and offset for
all other ip_summed by calling __tcp_v4_send_check.
Because of 2, we can limit the scope of the fix to virtio_net_hdr
that do try to set these fields, with a bogus value.
