====================
sctp: enhancements for the verification tag
This patchset is to address CVE-2021-3772:
A flaw was found in the Linux SCTP stack. A blind attacker may be able to
kill an existing SCTP association through invalid chunks if the attacker
knows the IP-addresses and port numbers being used and the attacker can
send packets with spoofed IP addresses.
This is caused by the missing VTAG verification for the received chunks
and the incorrect vtag for the ABORT used to reply to these invalid
chunks.
This patchset is to go over all processing functions for the received
chunks and do:
1. Make sure sctp_vtag_verify() is called firstly to verify the vtag from
the received chunk and discard this chunk if it fails. With some
exceptions:
a. sctp_sf_do_5_1B_init()/5_2_2_dupinit()/9_2_reshutack(), processing
INIT chunk, as sctphdr vtag is always 0 in INIT chunk.
b. sctp_sf_do_5_2_4_dupcook(), processing dupicate COOKIE_ECHO chunk,
as the vtag verification will be done by sctp_tietags_compare() and
then it takes right actions according to the return.
c. sctp_sf_shut_8_4_5(), processing SHUTDOWN_ACK chunk for cookie_wait
and cookie_echoed state, as RFC demand sending a SHUTDOWN_COMPLETE
even if the vtag verification failed.
d. sctp_sf_ootb(), called in many types of chunks for closed state or
no asoc, as the same reason to c.
2. Always use the vtag from the received INIT chunk to make the response
ABORT in sctp_ootb_pkt_new().
3. Fix the order for some checks and add some missing checks for the
received chunk.
This patch series has been tested with SCTP TAHI testing to make sure no
regression caused on protocol conformance.

sctp_sf_ootb() is called when processing DATA chunk in closed state,
and many other places are also using it.
The vtag in the chunk's sctphdr should be verified, otherwise, as
later in chunk length check, it may send abort with the existent
asoc's vtag, which can be exploited by one to cook a malicious
chunk to terminate a SCTP asoc.
When fails to verify the vtag from the chunk, this patch sets asoc
to NULL, so that the abort will be made with the vtag from the
received chunk later.

SHUTDOWN COMPLETE message will still be sent back to peer, but
with the vtag from SHUTDOWN-ACK chunk, as said in 5) of
rfc4960#section-8.4.
While at it, also remove the unnecessary chunk length check from
sctp_sf_shut_8_4_5(), as it's already done in both places where
it calls sctp_sf_shut_8_4_5().

1. In closed state: in sctp_sf_do_5_1D_ce():
When asoc is NULL, making packet for abort will use chunk's vtag
in sctp_ootb_pkt_new(). But when asoc exists, vtag from the chunk
should be verified before using peer.i.init_tag to make packet
for abort in sctp_ootb_pkt_new(), and just discard it if vtag is
not correct.
2. In the other states: in sctp_sf_do_5_2_4_dupcook():
asoc always exists, but duplicate cookie_echo's vtag will be
handled by sctp_tietags_compare() and then take actions, so before
that we only verify the vtag for the abort sent for invalid chunk
length.

Currently INIT_ACK chunk in non-cookie_echoed state is processed in
sctp_sf_discard_chunk() to send an abort with the existent asoc's
vtag if the chunk length is not valid. But the vtag in the chunk's
sctphdr is not verified, which may be exploited by one to cook a
malicious chunk to terminal a SCTP asoc.
sctp_sf_discard_chunk() also is called in many other places to send
an abort, and most of those have this problem. This patch is to fix
it by sending abort with the existent asoc's vtag only if the vtag
from the chunk's sctphdr is verified in sctp_sf_discard_chunk().
Note on sctp_sf_do_9_1_abort() and sctp_sf_shutdown_pending_abort(),
the chunk length has been verified before sctp_sf_discard_chunk(),
so replace it with sctp_sf_discard(). On sctp_sf_do_asconf_ack() and
sctp_sf_do_asconf(), move the sctp_chunk_length_valid check ahead of
sctp_sf_discard_chunk(), then replace it with sctp_sf_discard().

This patch fixes the problems below:
1. In non-shutdown_ack_sent states: in sctp_sf_do_5_1B_init() and
sctp_sf_do_5_2_2_dupinit():
chunk length check should be done before any checks that may cause
to send abort, as making packet for abort will access the init_tag
from init_hdr in sctp_ootb_pkt_new().
2. In shutdown_ack_sent state: in sctp_sf_do_9_2_reshutack():
The same checks as does in sctp_sf_do_5_2_2_dupinit() is needed
for sctp_sf_do_9_2_reshutack().

Currently Linux SCTP uses the verification tag of the existing SCTP
asoc when failing to process and sending the packet with the ABORT
chunk. This will result in the peer accepting the ABORT chunk and
removing the SCTP asoc. One could exploit this to terminate a SCTP
asoc.
This patch is to fix it by always using the initiate tag of the
received INIT chunk for the ABORT chunk to be sent.

Christoph Paasch reports [1] about incorrect skb->truesize
after skb_expand_head() call in ip6_xmit.
This may happen because of two reasons:
- skb_set_owner_w() for newly cloned skb is called too early,
before pskb_expand_head() where truesize is adjusted for (!skb-sk) case.
- pskb_expand_head() does not adjust truesize in (skb->sk) case.
In this case sk->sk_wmem_alloc should be adjusted too.

The PIO scratch buffer is larger than a single page, and therefore
it is not possible to copy it in a single step to vcpu->arch/pio_data.
Bound each call to emulator_pio_in/out to a single page; keep
track of how many I/O operations are left in vcpu->arch.sev_pio_count,
so that the operation can be restarted in the complete_userspace_io
callback.
For OUT, this means that the previous kvm_sev_es_outs implementation
becomes an iterator of the loop, and we can consume the sev_pio_data
buffer before leaving to userspace.
For IN, instead, consuming the buffer and decreasing sev_pio_count
is always done in the complete_userspace_io callback, because that
is when the memcpy is done into sev_pio_data.

emulator_pio_in handles both the case where the data is pending in
vcpu->arch.pio.count, and the case where I/O has to be done via either
an in-kernel device or a userspace exit. For SEV-ES we would like
to split these, to identify clearly the moment at which the
sev_pio_data is consumed. To this end, create two different
functions: __emulator_pio_in fills in vcpu->arch.pio.count, while
complete_emulator_pio_in clears it and releases vcpu->arch.pio.data.
Because this patch has to be backported, things are left a bit messy.
kernel_pio() operates on vcpu->arch.pio, which leads to emulator_pio_in()
having with two calls to complete_emulator_pio_in(). It will be fixed
in the next release.
While at it, remove the unused void* val argument of emulator_pio_in_out.
The function currently hardcodes vcpu->arch.pio_data as the
source/destination buffer, which sucks but will be fixed after the more
severe SEV-ES buffer overflow.
No functional change intended.

A few very small cleanups to the functions, smushed together because
the patch is already very small like this:
- inline emulator_pio_in_emulated and emulator_pio_out_emulated,
since we already have the vCPU
- remove the data argument and pull setting vcpu->arch.sev_pio_data into
the caller
- remove unnecessary clearing of vcpu->arch.pio.count when
emulation is done by the kernel (and therefore vcpu->arch.pio.count
is already clear on exit from emulator_pio_in and emulator_pio_out).
No functional change intended.

We will be using this field for OUTS emulation as well, in case the
data that is pushed via OUTS spans more than one page. In that case,
there will be a need to save the data pointer across exits to userspace.
So, change the name to something that refers to any kind of PIO.
Also spell out what it is used for, namely SEV-ES.

intel-gfx CI didn't spot this because we run each selftest in each own

we cross over the hardcoded limited of how many properties can be

Fix this by resetting the property count. Nothing else to clean up

operating on physical addresses can use __va() conversion.
Make sure that functions that mark allocated memory as MEMBLOCK_NOMAP
take care of informing kmemleak to ignore such memory.

Pull ucounts fixes from Eric Biederman:
"There has been one very hard to track down bug in the ucount code that
we have been tracking since roughly v5.14 was released. Alex managed
to find a reliable reproducer a few days ago and then I was able to
instrument the code and figure out what the issue was.
It turns out the sigqueue_alloc single atomic operation optimization
did not play nicely with ucounts multiple level rlimits. It turned out
that either sigqueue_alloc or sigqueue_free could be operating on
multiple levels and trigger the conditions for the optimization on
more than one level at the same time.
To deal with that situation I have introduced inc_rlimit_get_ucounts
and dec_rlimit_put_ucounts that just focuses on the optimization and
the rlimit and ucount changes.
While looking into the big bug I found I couple of other little issues
so I am including those fixes here as well.
When I have time I would very much like to dig into process ownership
of the shared signal queue and see if we could pick a single owner for
the entire queue so that all of the rlimits can count to that owner.
That should entirely remove the need to call get_ucounts and
put_ucounts in sigqueue_alloc and sigqueue_free. It is difficult
because Linux unlike POSIX supports setuid that works on a single
thread"

Another change to the API io-wq worker limitation API added in 5.15,
apply the limit to all prior users that already registered a tctx. It
may be confusing as it's now, in particular the change covers the
following 2 cases:
TASK1 | TASK2
_________________________________________________
ring = create() |
| limit_iowq_workers()
*not limited* |
TASK1 | TASK2
_________________________________________________
ring = create() |
| issue_requests()
limit_iowq_workers() |
| *not limited*
A note on locking, it's safe to traverse ->tctx_list as we hold
->uring_lock, but do that after dropping sqd->lock to avoid possible
problems. It's also safe to access tctx->io_wq there because tasks
kill it only after removing themselves from tctx_list, see
io_uring_cancel_generic() -> io_uring_clean_tctx()

PSP encrypts the data with the guest's key when writing to guest memory.
If the target memory was not previously encrypted, the cache may contain
dirty, unecrypted data that will persist on non-coherent systems.

When updating mmu->pkru_mask, the value can only be added but it isn't
reset in advance. This will make mmu->pkru_mask keep the stale data.
Fix this issue.

The enetc driver does not implement .ndo_change_mtu, instead it
configures the MAC register field PTC{Traffic Class}MSDUR[MAXSDU]
statically to a large value during probe time.
The driver used to configure only the max SDU for traffic class 0, and
that was fine while the driver could only use traffic class 0. But with
the introduction of mqprio, sending a large frame into any other TC than
0 is broken.
This patch fixes that by replicating per traffic class the static
configuration done in enetc_configure_port_mac().

There are two counters named "MAC tx frames", one of them is actually
incorrect. The correct name for that counter should be "MAC tx error
frames", which is symmetric to the existing "MAC rx error frames".
