As preparation for adding RTNL to make (*cmd->transcode)() and
(*cmd->transcode)() constantly protected by RTNL lock, we move out of
memory allocations existing between them as many as possible so that
the time of holding RTNL can be minimized in __tipc_nl_compat_doit().

netif_set_real_num_tx_queues() can be called when netdev is up.
That usually happens when user requests change of number of
channels/rings with ethtool -L. The procedure for changing
the number of queues involves resetting the qdiscs and setting
dev->num_tx_queues to the new value. When the new value is
lower than the old one, extra care has to be taken to ensure
ordering of accesses to the number of queues vs qdisc reset.
Currently the queues are reset before new dev->num_tx_queues
is assigned, leaving a window of time where packets can be
enqueued onto the queues going down, leading to a likely
crash in the drivers, since most drivers don't check if TX
skbs are assigned to an active queue.

Commit ebeeb1ad9b8a ("rds: tcp: use rds_destroy_pending() to synchronize
netns/module teardown and rds connection/workq management")
adds an rcu read critical section to __rd_conn_create. The
memory allocations in that critcal section need to use
GFP_ATOMIC to avoid sleeping.

The offending commit wrongly assumes 1:1 mapping between block and q.
However, there are multiple blocks for a single q for classful qdiscs.
Since the obscure tc_u_common sharing mechanism expects it to be shared
among a qdisc, fix it by storing q pointer in case the block is not
shared.

It is pointless to set block->q for block which are shared among
multiple qdiscs. So remove the assignment in that case. Do a bit of code
reshuffle to make block->index initialized at that point so we can use

for using rhashtable/rhlist.
The err '-EEXIST' introduced in Commit cd2b70875058 ("sctp: check

to that case.

Now br_sysfs_if file flush doesn't have attr show. To read it will
cause kernel panic after users chmod u+r this file.

chmod u+r /sys/devices/virtual/net/veth0/brport/flush
timeout 3 cat /sys/devices/virtual/net/veth0/brport/flush

This is the mindless scripted replacement of kernel use of POLL*
variables as described by Al, done by this script:
for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do
L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'`
for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done
done
with de-mangling cleanups yet to come.
NOTE! On almost all architectures, the EPOLL* constants have the same
values as the POLL* constants do. But they keyword here is "almost".
For various bad reasons they aren't the same, and epoll() doesn't
actually work quite correctly in some cases due to this on Sparc et al.
The next patch from Al will sort out the final differences, and we
should be all done.

Basically, that's what you suggested wrt KPOLL..., except that we can
use EPOLL... instead - they already are arch-independent (and equal to
what is currently kernel-side POLL...).
After the preparations (in this series) switch to returning EPOLL...
from ->poll() instances is completely mechanical and kernel-side
POLL... can go away. The last step (killing kernel-side POLL... and
unifying {de,}mangle_poll() has to be done after the
search-and-replace job, since we need userland-side POLL... for
unified {de,}mangle_poll(), thus the cherry-pick at the last step.
After that we will have:
- POLL{IN,OUT,...} *not* in __poll_t, so any stray instances of
->poll() still using those will be caught by sparse.
- eventpoll.c and select.c warning-free wrt __poll_t
- no more kernel-side definitions of POLL... - userland ones are
visible through the entire kernel (and used pretty much only for
mangle/demangle)
- same behavior as after the first series (i.e. sparc et.al. epoll(2)

When SCTP makes INIT or INIT_ACK packet the total chunk length

Here the chunk size for INIT_ACK packet becomes too big, mostly
because of the state cookie (INIT packet has large size with
many address parameters), plus additional server parameters.
Later this chunk causes the panic in skb_put_data():
skb_packet_transmit()
sctp_packet_pack()
skb_put_data(nskb, chunk->skb->data, chunk->skb->len);
'nskb' (head skb) was previously allocated with packet->size
from u16 'chunk->chunk_hdr->length'.
As suggested by Marcelo we should check the chunk's length in
_sctp_make_chunk() before trying to allocate skb for it and
discard a chunk if its size bigger than SCTP_MAX_CHUNK_LEN.

Daniel Borkmann says:
====================
pull-request: bpf 2018-02-09
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) Two fixes for BPF sockmap in order to break up circular map references
from programs attached to sockmap, and detaching related sockets in
case of socket close() event. For the latter we get rid of the
smap_state_change() and plug into ULP infrastructure, which will later
also be used for additional features anyway such as TX hooks. For the
second issue, dependency chain is broken up via map release callback
to free parse/verdict programs, all from John.
2) Fix a libbpf relocation issue that was found while implementing XDP
support for Suricata project. Issue was that when clang was invoked
with default target instead of bpf target, then various other e.g.
debugging relevant sections are added to the ELF file that contained
relocation entries pointing to non-BPF related sections which libbpf
trips over instead of skipping them. Test cases for libbpf are added
as well, from Jesper.
3) Various misc fixes for bpftool and one for libbpf: a small addition
to libbpf to make sure it recognizes all standard section prefixes.
Then, the Makefile in bpftool/Documentation is improved to explicitly
check for rst2man being installed on the system as we otherwise risk
installing empty man pages; the man page for bpftool-map is corrected
and a set of missing bash completions added in order to avoid shipping
bpftool where the completions are only partially working, from Quentin.
4) Fix applying the relocation to immediate load instructions in the
nfp JIT which were missing a shift, from Jakub.
5) Two fixes for the BPF kernel selftests: handle CONFIG_BPF_JIT_ALWAYS_ON=y
gracefully in test_bpf.ko module and mark them as FLAG_EXPECTED_FAIL
in this case; and explicitly delete the veth devices in the two tests
test_xdp_{meta,redirect}.sh before dismantling the netnses as when
selftests are run in batch mode, then workqueue to handle destruction
might not have finished yet and thus veth creation in next test under
same dev name would fail, from Yonghong.
6) Fix test_kmod.sh to check the test_bpf.ko module path before performing
an insmod, and fallback to modprobe. Especially the latter is useful
when having a device under test that has the modules installed instead,
from Naresh.

Hi folks,
On a multi-core machine, is it expected that we can have parallel RPCs
handled by each of the per-core workqueue?
In testing a read workload, observing via "top" command that a single
"kworker" thread is running servicing the requests (no parallelism).
It's more prominent while doing these operations over krb5p mount.
What has been suggested by Bruce is to try this and in my testing I
see then the read workload spread among all the kworker threads.

In commit d618d09a68e4 ("tipc: enforce valid ratio between skb truesize
and contents") we introduced a test for ensuring that the condition
truesize/datasize <= 4 is true for a received buffer. Unfortunately this
test has two problems.
- Because of the integer arithmetics the test
if (skb->truesize / buf_roundup_len(skb) > 4) will miss all
ratios [4 < ratio < 5], which was not the intention.
- The buffer returned by skb_copy() inherits skb->truesize of the
original buffer, which doesn't help the situation at all.
In this commit, we change the ratio condition and replace skb_copy()
with a call to skb_copy_expand() to finally get this right.

The error comes from u32_change() when comparing new and

mpls_label_ok() validates that the 'platform_label' array index from a
userspace netlink message payload is valid. Under speculation the
mpls_label_ok() result may not resolve in the CPU pipeline until after
the index is used to access an array element. Sanitize the index to zero
to prevent userspace-controlled arbitrary out-of-bounds speculation, a
precursor for a speculative execution side channel vulnerability.

An rds_connection can get added during netns deletion between lines 528
and 529 of
506 static void rds_tcp_kill_sock(struct net *net)
:
/* code to pull out all the rds_connections that should be destroyed */
:
528 spin_unlock_irq(&rds_tcp_conn_lock);
529 list_for_each_entry_safe(tc, _tc, &tmp_list, t_tcp_node)
530 rds_conn_destroy(tc->t_cpath->cp_conn);
Such an rds_connection would miss out the rds_conn_destroy()
loop (that cancels all pending work) and (if it was scheduled
after netns deletion) could trigger the use-after-free.
A similar race-window exists for the module unload path
in rds_tcp_exit -> rds_tcp_destroy_conns
Concurrency with netns deletion (rds_tcp_kill_sock()) must be handled
by checking check_net() before enqueuing new work or adding new
connections.
Concurrency with module-unload is handled by maintaining a module
specific flag that is set at the start of the module exit function,
and must be checked before enqueuing new work or adding new connections.
This commit refactors existing RDS_DESTROY_PENDING checks added by
commit 3db6e0d172c9 ("rds: use RCU to synchronize work-enqueue with
connection teardown") and consolidates all the concurrency checks
listed above into the function rds_destroy_pending().

Most callers of put_cmsg() use a "sizeof(foo)" for the length argument.
Within put_cmsg(), a copy_to_user() call is made with a dynamic size, as a
result of the cmsg header calculations. This means that hardened usercopy
will examine the copy, even though it was technically a fixed size and
should be implicitly whitelisted. All the put_cmsg() calls being built
from values in skbuff_head_cache are coming out of the protocol-defined
"cb" field, so whitelist this field entirely instead of creating per-use
bounce buffers, for which there are concerns about performance.
Original report was:
Bad or missing usercopy whitelist? Kernel memory exposure attempt detected from SLAB object 'skbuff_head_cache' (offset 64, size 16)!

Since we've added support for IFLA_IF_NETNSID for RTM_{DEL,GET,SET,NEW}LINK
it is possible for userspace to send us requests with three different
properties to identify a target network namespace. This affects at least
RTM_{NEW,SET}LINK. Each of them could potentially refer to a different
network namespace which is confusing. For legacy reasons the kernel will
pick the IFLA_NET_NS_PID property first and then look for the
IFLA_NET_NS_FD property but there is no reason to extend this type of
behavior to network namespace ids. The regression potential is quite
minimal since the rtnetlink requests in question either won't allow
IFLA_IF_NETNSID requests before 4.16 is out (RTM_{NEW,SET}LINK) or don't
support IFLA_NET_NS_{PID,FD} (RTM_{DEL,GET}LINK) in the first place.

However, there was no reason to stop the loop if a netns does not have

To avoid having the same problem in the future, I didn't take the

A single NFSv4 WRITE compound can often have three operations:
PUTFH, WRITE, then GETATTR.
When the WRITE payload is sent in a Read chunk, the client places
the GETATTR in the inline part of the RPC/RDMA message, just after
the WRITE operation (sans payload). The position value in the Read
chunk enables the receiver to insert the Read chunk at the correct
place in the received XDR stream; that is between the WRITE and
GETATTR.
According to RFC 8166, an NFS/RDMA client does not have to add XDR
round-up to the Read chunk that carries the WRITE payload. The
receiver adds XDR round-up padding if it is absent and the
receiver's XDR decoder requires it to be present.
Commit 193bcb7b3719 ("svcrdma: Populate tail iovec when receiving")
attempted to add support for receiving such a compound so that just
the WRITE payload appears in rq_arg's page list, and the trailing
GETATTR is placed in rq_arg's tail iovec. (TCP just strings the
whole compound into the head iovec and page list, without regard
to the alignment of the WRITE payload).
The server transport logic also had to accommodate the optional XDR
round-up of the Read chunk, which it did simply by lengthening the
tail iovec when round-up was needed. This approach is adequate for
the NFSv2 and NFSv3 WRITE decoders.
Unfortunately it is not sufficient for nfsd4_decode_write. When the
Read chunk length is a couple of bytes less than PAGE_SIZE, the
computation at the end of nfsd4_decode_write allows argp->pagelen to
go negative, which breaks the logic in read_buf that looks for the
tail iovec.
The result is that a WRITE operation whose payload length is just
less than a multiple of a page succeeds, but the subsequent GETATTR
in the same compound fails with NFS4ERR_OP_ILLEGAL because the XDR
decoder can't find it. Clients ignore the error, but they must
update their attribute cache via a separate round trip.
As nfsd4_decode_write appears to expect the payload itself to always
have appropriate XDR round-up, have svc_rdma_build_normal_read_chunk
add the Read chunk XDR round-up to the page_len rather than
lengthening the tail iovec.

Because of differences in how ipv4 and ipv6 handle fib lookups,
verification of nexthops with onlink flag need to default to the main
table rather than the local table used by IPv4. As it stands an
address within a connected route on device 1 can be used with
onlink on device 2. Updating the table properly rejects the route
due to the egress device mismatch.
Update the extack message as well to show it could be a device
mismatch for the nexthop spec.

AF_RXRPC is incorrectly sending back to the server any abort it receives
for a client connection. This is due to the final-ACK offload to the
connection event processor patch. The abort code is copied into the
last-call information on the connection channel and then the event
processor is set.
Instead, the following should be done:
(1) In the case of a final-ACK for a successful call, the ACK should be
scheduled as before.
(2) In the case of a locally generated ABORT, the ABORT details should be
cached for sending in response to further packets related to that
call and no further action scheduled at call disconnect time.
(3) In the case of an ACK received from the peer, the call should be
considered dead, no ABORT should be transmitted at this time. In
response to further non-ABORT packets from the peer relating to this
call, an RX_USER_ABORT ABORT should be transmitted.
(4) In the case of a call killed due to network error, an RX_USER_ABORT
ABORT should be cached for transmission in response to further
packets, but no ABORT should be sent at this time.

3) Flowtable infrastructure depends on NETFILTER_INGRESS as it registers
a hook for each flowtable, reported by John Crispin.
4) Missing initialization of info->priv in xt_cgroup version 1, from

5) Give a chance to garbage collector to run after scheduling flowtable
cleanup.
6) Releasing flowtable content on nft_flow_offload module removal is
not required at all, there is not dependencies between this module
and flowtables, remove it.
7) Fix missing xt_rateest_mutex grabbing for hash insertions, also from
Cong Wang.
8) Move nf_flow_table_cleanup() routine to flowtable core, this patch is
a dependency for the next patch in this list.
9) Flowtable resources are not properly released on removal from the
control plane. Fix this resource leak by scheduling removal of all
entries and explicit call to the garbage collector.
10) nf_ct_nat_offset() declaration is dead code, this function prototype
is not used anywhere, remove it. From Taehee Yoo.

flow_offload_del frees the flow, so all associated resource must be
freed before.
Since the ct entry in struct flow_offload_entry was allocated by
flow_offload_alloc, it should be freed by flow_offload_free to take care
of the error handling path when flow_offload_add fails.
While at it, make flow_offload_del static, since it should never be
