      igc: Fix not considering the TX delay for timestamps · 4406e977
      Vinicius Costa Gomes authored 
      When timestamping a packet there's a delay between the start of the
packet and the point where the hardware actually captures the
timestamp. This difference needs to be considered if we want accurate
timestamps.

This was done on the RX side, but not on the TX side.

      igc: Fix wrong timestamp latency numbers · f03369b9
      Vinicius Costa Gomes authored 
      The previous timestamping latency numbers were obtained by
interpolating the i210 numbers with the i225 crystal clock value. That
calculation was wrong.

Use the correct values from real measurements.

      i40e: always propagate error value in i40e_set_vsi_promisc() · b6f23d38
      Stefan Assmann authored 
      The for loop in i40e_set_vsi_promisc() reports errors via dev_err() but
does not propagate the error up the call chain. Instead it continues the
loop and potentially overwrites the reported error value.
This results in the error being recorded in the log buffer, but the
caller might never know anything went the wrong way.

To avoid this situation i40e_set_vsi_promisc() needs to temporarily store
the error after reporting it. This is still not optimal as multiple
different errors may occur, so store the first error and hope that's
the main issue.

      i40e: fix return of uninitialized aq_ret in i40e_set_vsi_promisc · e1e1b535
      Stefan Assmann authored 
      drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c: In function ‘i40e_set_vsi_promisc’:
drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c:1176:14: error: ‘aq_ret’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
  i40e_status aq_ret;

In case the code inside the if statement and the for loop does not get
executed aq_ret will be uninitialized when the variable gets returned at
the end of the function.

Avoid this by changing num_vlans from int to u16, so aq_ret always gets
set. Making this change in additional places as num_vlans should never
be negative.

====================
wireguard fixes for 5.9-rc5

Yesterday, Eric reported a race condition found by syzbot. This series
contains two commits, one that fixes the direct issue, and another that
addresses the more general issue, as a defense in depth.

1) The basic problem syzbot unearthed was that one particular mutation
   of handshake->entry was not protected by the handshake mutex like the
   other cases, so this patch basically just reorders a line to make
   sure the mutex is actually taken at the right point. Most of the work
   here went into making sure the race was fully understood and making a
   reproducer (which syzbot was unable to do itself, due to the rarity
   of the race).

2) Eric's initial suggestion for fixing this was taking a spinlock
   around the hash table replace function where the null ptr deref was
   happening. This doesn't address the main problem in the most precise
   possible way like (1) does, but it is a good suggestion for
   defense-in-depth, in case related issues come up in the future, and
   basically costs nothing from a performance perspective. I thought it
   aided in implementing a good general rule: all mutators of that hash
   table take the table lock. So that's part of this series as a
   companion.

Both of these contain Fixes: tags and are good candidates for stable.

      wireguard: peerlookup: take lock before checking hash in replace operation · 6147f7b1
      Jason A. Donenfeld authored 
      Eric's suggested fix for the previous commit's mentioned race condition
was to simply take the table->lock in wg_index_hashtable_replace(). The
table->lock of the hash table is supposed to protect the bucket heads,
not the entires, but actually, since all the mutator functions are
already taking it, it makes sense to take it too for the test to
hlist_unhashed, as a defense in depth measure, so that it no longer
races with deletions, regardless of what other locks are protecting
individual entries. This is sensible from a performance perspective
because, as Eric pointed out, the case of being unhashed is already the
unlikely case, so this won't add common contention. And comparing
instructions, this basically doesn't make much of a difference other
than pushing and popping %r13, used by the new `bool ret`. More
generally, I like the idea of locking consistency across table mutator
functions, and this might let me rest slightly easier at night.

      wireguard: noise: take lock when removing handshake entry from table · 9179ba31
      Jason A. Donenfeld authored 
      Eric reported that syzkaller found a race of this variety:

CPU 1                                       CPU 2
-------------------------------------------|---------------------------------------
wg_index_hashtable_replace(old, ...)       |
  if (hlist_unhashed(&old->index_hash))    |
                                           | wg_index_hashtable_remove(old)
                                           |   hlist_del_init_rcu(&old->index_hash)
				           |     old->index_hash.pprev = NULL
  hlist_replace_rcu(&old->index_hash, ...) |
    *old->index_hash.pprev                 |

Syzbot wasn't actually able to reproduce this more than once or create a
reproducer, because the race window between checking "hlist_unhashed" and
calling "hlist_replace_rcu" is just so small. Adding an mdelay(5) or
similar there helps make this demonstrable using this simple script:

    #!/bin/bash
    set -ex
    trap 'kill $pid1; kill $pid2; ip link del wg0; ip link del wg1' EXIT
    ip link add wg0 type wireguard
    ip link add wg1 type wireguard
    wg set wg0 private-key <(wg genkey) listen-port 9999
    wg set wg1 private-key <(wg genkey) peer $(wg show wg0 public-key) endpoint 127.0.0.1:9999 persistent-keepalive 1
    wg set wg0 peer $(wg show wg1 public-key)
    ip link set wg0 up
    yes link set wg1 up | ip -force -batch - &
    pid1=$!
    yes link set wg1 down | ip -force -batch - &
    pid2=$!
    wait

The fundumental underlying problem is that we permit calls to wg_index_
hashtable_remove(handshake.entry) without requiring the caller to take
the handshake mutex that is intended to protect members of handshake
during mutations. This is consistently the case with calls to wg_index_
hashtable_insert(handshake.entry) and wg_index_hashtable_replace(
handshake.entry), but it's missing from a pertinent callsite of wg_
index_hashtable_remove(handshake.entry). So, this patch makes sure that
mutex is taken.

The original code was a little bit funky though, in the form of:

    remove(handshake.entry)
    lock(), memzero(handshake.some_members), unlock()
    remove(handshake.entry)

The original intention of that double removal pattern outside the lock
appears to be some attempt to prevent insertions that might happen while
locks are dropped during expensive crypto operations, but actually, all
callers of wg_index_hashtable_insert(handshake.entry) take the write
lock and then explicitly check handshake.state, as they should, which
the aforementioned memzero clears, which means an insertion should
already be impossible. And regardless, the original intention was
necessarily racy, since it wasn't guaranteed that something else would
run after the unlock() instead of after the remove(). So, from a
soundness perspective, it seems positive to remove what looks like a
hack at best.

The crash from both syzbot and from the script above is as follows:
