      net: cdc_ncm: Allow for dwNtbOutMaxSize to be unset or zero · 2be6d4d1
      Lee Jones authored 
      Currently, due to the sequential use of min_t() and clamp_t() macros,
in cdc_ncm_check_tx_max(), if dwNtbOutMaxSize is not set, the logic
sets tx_max to 0.  This is then used to allocate the data area of the
SKB requested later in cdc_ncm_fill_tx_frame().

This does not cause an issue presently because when memory is
allocated during initialisation phase of SKB creation, more memory
(512b) is allocated than is required for the SKB headers alone (320b),
leaving some space (512b - 320b = 192b) for CDC data (172b).

However, if more elements (for example 3 x u64 = [24b]) were added to
one of the SKB header structs, say 'struct skb_shared_info',
increasing its original size (320b [320b aligned]) to something larger
(344b [384b aligned]), then suddenly the CDC data (172b) no longer
fits in the spare SKB data area (512b - 384b = 128b).

Consequently the SKB bounds checking semantics fails and panics:

  skbuff: skb_over_panic: text:ffffffff830a5b5f len:184 put:172   \
     head:ffff888119227c00 data:ffff888119227c00 tail:0xb8 end:0x80 dev:<NULL>

By overriding the max value with the default CDC_NCM_NTB_MAX_SIZE_TX
when not offered through the system provided params, we ensure enough
data space is allocated to handle the CDC data, meaning no crash will
occur.

      qede: validate non LSO skb length · 8e227b19
      Manish Chopra authored 
      Although it is unlikely that stack could transmit a non LSO
skb with length > MTU, however in some cases or environment such
occurrences actually resulted into firmware asserts due to packet
length being greater than the max supported by the device (~9700B).

This patch adds the safeguard for such odd cases to avoid firmware
asserts.

v2: Added "Fixes" tag with one of the initial driver commit
    which enabled the TX traffic actually (as this was probably
    day1 issue which was discovered recently by some customer
    environment)

      tcp: fix another uninit-value (sk_rx_queue_mapping) · 03cfda4f
      Eric Dumazet authored 
      KMSAN is still not happy [1].

I missed that passive connections do not inherit their
sk_rx_queue_mapping values from the request socket,
but instead tcp_child_process() is calling
sk_mark_napi_id(child, skb)

We have many sk_mark_napi_id() callers, so I am providing
a new helper, forcing the setting sk_rx_queue_mapping
and sk_napi_id.

Note that we had no KMSAN report for sk_napi_id because
passive connections got a copy of this field from the listener.
sk_rx_queue_mapping in the other hand is inside the
sk_dontcopy_begin/sk_dontcopy_end so sk_clone_lock()
leaves this field uninitialized.

We might remove dead code populating req->sk_rx_queue_mapping
in the future.

      selftests/fib_tests: Rework fib_rp_filter_test() · f6071e5e
      Peilin Ye authored 
      Currently rp_filter tests in fib_tests.sh:fib_rp_filter_test() are
failing.  ping sockets are bound to dummy1 using the "-I" option
(SO_BINDTODEVICE), but socket lookup is failing when receiving ping
replies, since the routing table thinks they belong to dummy0.

For example, suppose ping is using a SOCK_RAW socket for ICMP messages.
When receiving ping replies, in __raw_v4_lookup(), sk->sk_bound_dev_if
is 3 (dummy1), but dif (skb_rtable(skb)->rt_iif) says 2 (dummy0), so the
raw_sk_bound_dev_eq() check fails.  Similar things happen in
ping_lookup() for SOCK_DGRAM sockets.

These tests used to pass due to a bug [1] in iputils, where "ping -I"
actually did not bind ICMP message sockets to device.  The bug has been
fixed by iputils commit f455fee41c07 ("ping: also bind the ICMP socket
to the specific device") in 2016, which is why our rp_filter tests
started to fail.  See [2] .

Fixing the tests while keeping everything in one netns turns out to be
nontrivial.  Rework the tests and build the following topology:

 ┌─────────────────────────────┐    ┌─────────────────────────────┐
 │  network namespace 1 (ns1)  │    │  network namespace 2 (ns2)  │

Consider sending an ICMP_ECHO packet A in ns2.  Both source and
destination IP addresses are 192.0.2.1, and we use strict mode rp_filter
in both ns1 and ns2:

  1. A is routed to lo since its destination IP address is one of ns2's
     local addresses (veth2);
  2. A is redirected from lo's egress to veth2's egress using mirred;
  3. A arrives at veth1's ingress in ns1;
  4. A is redirected from veth1's ingress to lo's ingress, again, using
     mirred;
  5. In __fib_validate_source(), fib_info_nh_uses_dev() returns false,
     since A was received on lo, but reverse path lookup says veth1;
  6. However A is not dropped since we have relaxed this check for lo in
     commit 66f82095 ("fib: relax source validation check for loopback
     packets");

Making sure A is not dropped here in this corner case is the whole point
of having this test.

  7. As A reaches the ICMP layer, an ICMP_ECHOREPLY packet, B, is
     generated;
  8. Similarly, B is redirected from lo's egress to veth1's egress (in
     ns1), then redirected once again from veth2's ingress to lo's
     ingress (in ns2), using mirred.

Also test "ping 127.0.0.1" from ns2.  It does not trigger the relaxed
check in __fib_validate_source(), but just to make sure the topology
works with loopback addresses.

Tested with ping from iputils 20210722-41-gf9fb573:

$ ./fib_tests.sh -t rp_filter

IPv4 rp_filter tests
    TEST: rp_filter passes local packets		[ OK ]
    TEST: rp_filter passes loopback packets		[ OK ]

      Pull networking fixes from Jakub Kicinski:
 "Including fixes from wireless, and wireguard.

  Mostly scattered driver changes this week, with one big clump in
  mv88e6xxx. Nothing of note, really.

  Current release - regressions:

   - smc: keep smc_close_final()'s error code during active close

  Current release - new code bugs:

   - iwlwifi: various static checker fixes (int overflow, leaks, missing
     error codes)

   - rtw89: fix size of firmware header before transfer, avoid crash

   - mt76: fix timestamp check in tx_status; fix pktid leak;

   - mscc: ocelot: fix missing unlock on error in ocelot_hwstamp_set()

  Previous releases - regressions:

   - smc: fix list corruption in smc_lgr_cleanup_early

   - ipv4: convert fib_num_tclassid_users to atomic_t

  Previous releases - always broken:

   - tls: fix authentication failure in CCM mode

   - vrf: reset IPCB/IP6CB when processing outbound pkts, prevent
     incorrect processing

   - dsa: mv88e6xxx: fixes for various device errata

   - rds: correct socket tunable error in rds_tcp_tune()

   - ipv6: fix memory leak in fib6_rule_suppress

   - wireguard: reset peer src endpoint when netns exits

   - wireguard: improve resilience to DoS around incoming handshakes

   - tcp: fix page frag corruption on page fault which involves TCP

   - mpls: fix missing attributes in delete notifications

   - mt7915: fix NULL pointer dereference with ad-hoc mode

  Misc:

   - rt2x00: be more lenient about EPROTO errors during start

   - mlx4_en: update reported link modes for 1/10G"
