mm/migrate.c: remove MIGRATE_PFN_LOCKED
MIGRATE_PFN_LOCKED is used to indicate to migrate_vma_prepare() that a
source page was already locked during migrate_vma_collect(). If it
wasn't then the a second attempt is made to lock the page. However if
the first attempt failed it's unlikely a second attempt will succeed,
and the retry adds complexity. So clean this up by removing the retry
and MIGRATE_PFN_LOCKED flag.
Destination pages are also meant to have the MIGRATE_PFN_LOCKED flag

There is no need to validate the file-backed page's refcount before
trying to freeze the page's expected refcount, instead we can rely on
the folio_ref_freeze() to validate if the page has the expected refcount
before migrating its mapping.
Moreover we are always under the page lock when migrating the page
mapping, which means nowhere else can remove it from the page cache, so
we can remove the xas_load() validation under the i_pages lock.

mm: allow only SLUB on PREEMPT_RT
Memory allocators may disable interrupts or preemption as part of the
allocation and freeing process. For PREEMPT_RT it is important that
these sections remain deterministic and short and therefore don't depend
on the size of the memory to allocate/ free or the inner state of the
algorithm.
Until v3.12-RT the SLAB allocator was an option but involved several
changes to meet all the requirements. The SLUB design fits better with
PREEMPT_RT model and so the SLAB patches were dropped in the 3.12-RT
patchset. Comparing the two allocator, SLUB outperformed SLAB in both
throughput (time needed to allocate and free memory) and the maximal
latency of the system measured with cyclictest during hackbench.
SLOB was never evaluated since it was unlikely that it preforms better
than SLAB. During a quick test, the kernel crashed with SLOB enabled
during boot.
Disable SLAB and SLOB on PREEMPT_RT.

net: fix premature exit from NAPI state polling in napi_disable()
Commit fcf38d026808 ("net: make napi_disable() symmetric with

BUG when bringing an iface up/down under heavy traffic load.
Prior to this commit, napi_disable() was polling n->state until
none of (NAPIF_STATE_SCHED | NAPIF_STATE_NPSVC) is set and then
always flip them. Now there's a possibility to get away with the
NAPIF_STATE_SCHE unset as 'continue' drops us to the cmpxchg()
call with an uninitialized variable, rather than straight to
another round of the state check.
Error path looks like:
napi_disable():
unsigned long val, new; /* new is uninitialized */
do {
val = READ_ONCE(n->state); /* NAPIF_STATE_NPSVC and/or
NAPIF_STATE_SCHED is set */
if (val & (NAPIF_STATE_SCHED | NAPIF_STATE_NPSVC)) { /* true */
usleep_range(20, 200);
continue; /* go straight to the condition check */
}
new = val | <...>
} while (cmpxchg(&n->state, val, new) != val); /* state == val, cmpxchg()
writes garbage */
napi_enable():

Pull exit cleanups from Eric Biederman:
"While looking at some issues related to the exit path in the kernel I
found several instances where the code is not using the existing
abstractions properly.
This set of changes introduces force_fatal_sig a way of sending a
signal and not allowing it to be caught, and corrects the misuse of
the existing abstractions that I found.
A lot of the misuse of the existing abstractions are silly things such
as doing something after calling a no return function, rolling BUG by
hand, doing more work than necessary to terminate a kernel thread, or
calling do_exit(SIGKILL) instead of calling force_sig(SIGKILL).
In the review a deficiency in force_fatal_sig and force_sig_seccomp
where ptrace or sigaction could prevent the delivery of the signal was
found. I have added a change that adds SA_IMMUTABLE to change that
makes it impossible to interrupt the delivery of those signals, and
allows backporting to fix force_sig_seccomp
And Arnd found an issue where a function passed to kthread_run had the
wrong prototype, and after my cleanup was failing to build."

would indicate that the new core scheduling domain encompasses all
tasks in the process group of <pid>. Specifying 0 would only create a
core scheduling domain for the thread identified by <pid> and 2 would
encompass the whole thread-group of <pid>.
Note, the values 0, 1, and 2 correspond to PIDTYPE_PID, PIDTYPE_TGID,
and PIDTYPE_PGID. A first version tried to expose those values
directly to which I objected because:
- PIDTYPE_* is an enum that is kernel internal which we should not
expose to userspace directly.
- PIDTYPE_* indicates what a given struct pid is used for it doesn't
express a scope.
But what the 4th argument of PR_SCHED_CORE prctl() expresses is the
scope of the operation, i.e. the scope of the core scheduling domain
at creation time. So Eugene's patch now simply introduces three new
defines PR_SCHED_CORE_SCOPE_THREAD, PR_SCHED_CORE_SCOPE_THREAD_GROUP,
and PR_SCHED_CORE_SCOPE_PROCESS_GROUP. They simply express what
happens.
This has been on the mailing list for quite a while with all relevant
scheduler folks Cced. I announced multiple times that I'd pick this up
if I don't see or her anyone else doing it. None of this touches
proper scheduler code but only concerns uapi so I think this is fine.
With core scheduling being quite common now for vm managers (e.g.
moving individual vcpu threads into their own core scheduling domain)
and container managers (e.g. moving the init process into its own core
scheduling domain and letting all created children inherit it) having
to rely on raw numbers passed as the 4th argument in prctl() is a bit
annoying and everyone is starting to come up with their own defines"

"Various places in the kernel have picked up pidfds.
The two most recent additions have probably been the ability to use
pidfds in bpf maps and the usage of pidfds in mm-based syscalls such
as process_mrelease() and process_madvise().
The same pattern to turn a pidfd into a struct task exists in two
places. One of those places used PIDTYPE_TGID while the other one used
PIDTYPE_PID even though it is clearly documented in all pidfd-helpers
that pidfds __currently__ only refer to thread-group leaders (subject
to change in the future if need be).
This isn't a bug per se but has the potential to be one if we allow
pidfds to refer to individual threads. If that happens we want to
audit all codepaths that make use of them to ensure they can deal with
pidfds refering to individual threads.
This adds a simple helper to turn a pidfd into a struct task making it
easy to grep for such places. Plus, it gets rid of code-duplication"

But this was very slow, due to performing a synchronization for each CPU.
The code was reshuffled to do one disabling of all CPU buffers, followed
by a single RCU synchronization, and then the resetting of each of the CPU
buffers. But unfortunately, the mutex that prevented multiple occurrences

net/smc: fix sk_refcnt underflow on linkdown and fallback
We got the following WARNING when running ab/nginx
test with RDMA link flapping (up-down-up).
The reason is when smc_sock fallback and at linkdown
happens simultaneously, we may got the following situation:
smc_sock was set to SMC_CLOSED and sock_put() been called
when terminate the link group. But later application call
close() on the socket, then we got:
__smc_release():
if (smc_sock->fallback)
smc_sock->sk_state = SMC_CLOSED
sock_put(smc_sock)
Again we set the smc_sock to CLOSED through it's already

selftests: forwarding: Fix packet matching in mirroring selftests
In commit 1008761ac751 ("cls_flower: Fix inability to match GRE/IPIP
packets"), cls_flower was fixed to match an outer packet of a tunneled
packet as would be expected, rather than dissecting to the inner packet and
matching on that.
This fix uncovered several issues in packet matching in mirroring
selftests:
- in mirror_gre_bridge_1d_vlan.sh and mirror_gre_vlan_bridge_1q.sh, the
vlan_ethtype match is copied around as "ip", even as some of the tests
are running over ip6gretap. This is fixed by using an "ipv6" for
vlan_ethtype in the ip6gretap tests.
- in mirror_gre_changes.sh, a filter to count GRE packets is set up to
match TTL of 50. This used to trigger in the offloaded datapath, where
the envelope TTL was matched, but not in the software datapath, which
considered TTL of the inner packet. Now that both match consistently, all
the packets were double-counted. This is fixed by marking the filter as
skip_hw, leaving only the SW datapath component active.

net: marvell: mvpp2: Fix wrong SerDes reconfiguration order
Commit 5481a219583b ("net: mvpp2: convert to use
mac_prepare()/mac_finish()") introduced a bug wherein it leaves the MAC
RESET register asserted after mac_finish(), due to wrong order of
function calls.
Before it was:
.mac_config()
mvpp22_mode_reconfigure()
assert reset
mvpp2_xlg_config()
deassert reset
Now it is:
.mac_prepare()
.mac_config()
mvpp2_xlg_config()
deassert reset
.mac_finish()
mvpp2_xlg_config()
assert reset
Obviously this is wrong.
This bug is triggered when phylink tries to change the PHY interface
mode from a GMAC mode (sgmii, 1000base-x, 2500base-x) to XLG mode
(10gbase-r, xaui). The XLG mode does not work since reset is left
asserted. Only after
ifconfig down && ifconfig up
is called will the XLG mode work.
Move the call to mvpp22_mode_reconfigure() to .mac_prepare()
implementation. Since some of the subsequent functions need to know
whether the interface is being changed, we unfortunately also need to
pass around the new interface mode before setting port->phy_interface.

Fix by setting a unique MAC address on each simulated VM interface.
