UPSTREAM: inet: fully convert sk->sk_rx_dst to RCU rules
commit 8f905c0e7354ef261360fb7535ea079b1082c105 upstream. syzbot reported various issues around early demux, one being included in this changelog [1] sk->sk_rx_dst is using RCU protection without clearly documenting it. And following sequences in tcp_v4_do_rcv()/tcp_v6_do_rcv() are not following standard RCU rules. [a] dst_release(dst); [b] sk->sk_rx_dst = NULL; They look wrong because a delete operation of RCU protected pointer is supposed to clear the pointer before the call_rcu()/synchronize_rcu() guarding actual memory freeing. In some cases indeed, dst could be freed before [b] is done. We could cheat by clearing sk_rx_dst before calling dst_release(), but this seems the right time to stick to standard RCU annotations and debugging facilities.

tcp: fix early ETIMEDOUT after spurious non-SACK RTO
[ Upstream commit 686dc2db2a0fdc1d34b424ec2c0a735becd8d62b ]
Fix a bug reported and analyzed by Nagaraj Arankal, where the handling
of a spurious non-SACK RTO could cause a connection to fail to clear
retrans_stamp, causing a later RTO to very prematurely time out the
connection with ETIMEDOUT.
Here is the buggy scenario, expanding upon Nagaraj Arankal's excellent
report:
(*1) Send one data packet on a non-SACK connection
(*2) Because no ACK packet is received, the packet is retransmitted
and we enter CA_Loss; but this retransmission is spurious.
(*3) The ACK for the original data is received. The transmitted packet
is acknowledged. The TCP timestamp is before the retrans_stamp,
so tcp_may_undo() returns true, and tcp_try_undo_loss() returns
true without changing state to Open (because tcp_is_sack() is
false), and tcp_process_loss() returns without calling
tcp_try_undo_recovery(). Normally after undoing a CA_Loss
episode, tcp_fastretrans_alert() would see that the connection
has returned to CA_Open and fall through and call
tcp_try_to_open(), which would set retrans_stamp to 0. However,
for non-SACK connections we hold the connection in CA_Loss, so do
not fall through to call tcp_try_to_open() and do not set
retrans_stamp to 0. So retrans_stamp is (erroneously) still
non-zero.
At this point the first "retransmission event" has passed and
been recovered from. Any future retransmission is a completely
new "event". However, retrans_stamp is erroneously still
set. (And we are still in CA_Loss, which is correct.)
(*4) After 16 minutes (to correspond with tcp_retries2=15), a new data
packet is sent. Note: No data is transmitted between (*3) and
(*4) and we disabled keep alives.
The socket's timeout SHOULD be calculated from this point in
time, but instead it's calculated from the prior "event" 16
minutes ago (step (*2)).
(*5) Because no ACK packet is received, the packet is retransmitted.
(*6) At the time of the 2nd retransmission, the socket returns
ETIMEDOUT, prematurely, because retrans_stamp is (erroneously)
too far in the past (set at the time of (*2)).
This commit fixes this bug by ensuring that we reuse in
tcp_try_undo_loss() the same careful logic for non-SACK connections
that we have in tcp_try_undo_recovery(). To avoid duplicating logic,
we factor out that logic into a new
tcp_is_non_sack_preventing_reopen() helper and call that helper from
both undo functions.

tcp: annotate data-race around challenge_timestamp
[ Upstream commit 8c70521238b7863c2af607e20bcba20f974c969b ]
challenge_timestamp can be read an written by concurrent threads.
This was expected, but we need to annotate the race to avoid potential issues.
Following patch moves challenge_timestamp and challenge_count
to per-netns storage to provide better isolation.

tcp: tweak len/truesize ratio for coalesce candidates
[ Upstream commit 240bfd134c592791fdceba1ce7fc3f973c33df2d ] tcp_grow_window() is using skb->len/skb->truesize to increase tp->rcv_ssthresh which has a direct impact on advertized window sizes. We added TCP coalescing in linux-3.4 & linux-3.5: Instead of storing skbs with one or two MSS in receive queue (or OFO queue), we try to append segments together to reduce memory overhead. High performance network drivers tend to cook skb with 3 parts : 1) sk_buff structure (256 bytes) 2) skb->head contains room to copy headers as needed, and skb_shared_info 3) page fragment(s) containing the ~1514 bytes frame (or more depending on MTU) Once coalesced into a previous skb, 1) and 2) are freed. We can therefore tweak the way we compute len/truesize ratio knowing that skb->truesize is inflated by 1) and 2) soon to be freed. This is done only for in-order skb, or skb coalesced into OFO queue. The result is that low rate flows no longer pay the memory price of having low GRO aggregation factor. Same result for drivers not using GRO. This is critical to allow a big enough receiver window, typically tcp_rmem[2] / 2. We have been using this at Google for about 5 years, it is due time to make it upstream.

tcp: fix tcp_mtup_probe_success vs wrong snd_cwnd
commit 11825765291a93d8e7f44230da67b9f607c777bf upstream.
syzbot got a new report [1] finally pointing to a very old bug,
added in initial support for MTU probing.
tcp_mtu_probe() has checks about starting an MTU probe if
tcp_snd_cwnd(tp) >= 11.
But nothing prevents tcp_snd_cwnd(tp) to be reduced later
and before the MTU probe succeeds.
This bug would lead to potential zero-divides.
Debugging added in commit 40570375356c ("tcp: add accessors
to read/set tp->snd_cwnd") has paid off :)
While we are at it, address potential overflows in this code.

tcp: fix F-RTO may not work correctly when receiving DSACK
[ Upstream commit d9157f6806d1499e173770df1f1b234763de5c79 ]
Currently DSACK is regarded as a dupack, which may cause
F-RTO to incorrectly enter "loss was real" when receiving
DSACK.
Packetdrill to demonstrate:
// Enable F-RTO and TLP
0 `sysctl -q net.ipv4.tcp_frto=2`
0 `sysctl -q net.ipv4.tcp_early_retrans=3`
0 `sysctl -q net.ipv4.tcp_congestion_control=cubic`
// Establish a connection
+0 socket(..., SOCK_STREAM, IPPROTO_TCP) = 3
+0 setsockopt(3, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0
+0 bind(3, ..., ...) = 0
+0 listen(3, 1) = 0
// RTT 10ms, RTO 210ms
+.1 < S 0:0(0) win 32792 <mss 1000,sackOK,nop,nop,nop,wscale 7>
+0 > S. 0:0(0) ack 1 <...>
+.01 < . 1:1(0) ack 1 win 257
+0 accept(3, ..., ...) = 4
// Send 2 data segments
+0 write(4, ..., 2000) = 2000
+0 > P. 1:2001(2000) ack 1
// TLP
+.022 > P. 1001:2001(1000) ack 1
// Continue to send 8 data segments
+0 write(4, ..., 10000) = 10000
+0 > P. 2001:10001(8000) ack 1
// RTO
+.188 > . 1:1001(1000) ack 1
// The original data is acked and new data is sent(F-RTO step 2.b)
+0 < . 1:1(0) ack 2001 win 257
+0 > P. 10001:12001(2000) ack 1
// D-SACK caused by TLP is regarded as a dupack, this results in
// the incorrect judgment of "loss was real"(F-RTO step 3.a)
+.022 < . 1:1(0) ack 2001 win 257 <sack 1001:2001,nop,nop>
// Never-retransmitted data(3001:4001) are acked and

commit b67985be400969578d4d4b17299714c0e5d2c07b upstream. tcp_shift_skb_data() might collapse three packets into a larger one. P_A, P_B, P_C -> P_ABC Historically, it used a single tcp_skb_can_collapse_to(P_A) call, because it was enough. In commit |

tcp: fix tcp_init_transfer() to not reset icsk_ca_initialized
commit be5d1b61a2ad28c7e57fe8bfa277373e8ecffcdc upstream. This commit fixes a bug (found by syzkaller) that could cause spurious double-initializations for congestion control modules, which could cause memory leaks or other problems for congestion control modules (like CDG) that allocate memory in their init functions. The buggy scenario constructed by syzkaller was something like: (1) create a TCP socket (2) initiate a TFO connect via sendto() (3) while socket is in TCP_SYN_SENT, call setsockopt(TCP_CONGESTION), which calls: tcp_set_congestion_control() -> tcp_reinit_congestion_control() -> tcp_init_congestion_control() (4) receive ACK, connection is established, call tcp_init_transfer(), set icsk_ca_initialized=0 (without first calling cc->release()), call tcp_init_congestion_control() again. Note that in this sequence tcp_init_congestion_control() is called twice without a cc->release() call in between. Thus, for CC modules that allocate memory in their init() function, e.g, CDG, a memory leak may occur. The syzkaller tool managed to find a reproducer that triggered such a leak in CDG. The bug was introduced when that commit |

net: tcp better handling of reordering then loss cases
[ Upstream commit a29cb6914681a55667436a9eb7a42e28da8cf387 ] This patch aims to improve the situation when reordering and loss are ocurring in the same flight of packets. Previously the reordering would first induce a spurious recovery, then the subsequent ACK may undo the cwnd (based on the timestamps e.g.). However the current loss recovery does not proceed to invoke RACK to install a reordering timer. If some packets are also lost, this may lead to a long RTO-based recovery. An example is https://groups.google.com/g/bbr-dev/c/OFHADvJbTEI The solution is to after reverting the recovery, always invoke RACK to either mount the RACK timer to fast retransmit after the reordering window, or restarts the recovery if new loss is identified. Hence it is possible the sender may go from Recovery to Disorder/Open to Recovery again in one ACK.

tcp: fix TLP timer not set when CA_STATE changes from DISORDER to OPEN
commit 62d9f1a6945ba69c125e548e72a36d203b30596e upstream.
Upon receiving a cumulative ACK that changes the congestion state from
Disorder to Open, the TLP timer is not set. If the sender is app-limited,
it can only wait for the RTO timer to expire and retransmit.
The reason for this is that the TLP timer is set before the congestion
state changes in tcp_ack(), so we delay the time point of calling
tcp_set_xmit_timer() until after tcp_fastretrans_alert() returns and
remove the FLAG_SET_XMIT_TIMER from ack_flag when the RACK reorder timer
is set.
This commit has two additional benefits:
1) Make sure to reset RTO according to RFC6298 when receiving ACK, to
avoid spurious RTO caused by RTO timer early expires.
2) Reduce the xmit timer reschedule once per ACK when the RACK reorder
timer is set.

tcp: make TCP_USER_TIMEOUT accurate for zero window probes
commit 344db93ae3ee69fc137bd6ed89a8ff1bf5b0db08 upstream. The TCP_USER_TIMEOUT is checked by the 0-window probe timer. As the timer has backoff with a max interval of about two minutes, the actual timeout for TCP_USER_TIMEOUT can be off by up to two minutes. In this patch the TCP_USER_TIMEOUT is made more accurate by taking it into account when computing the timer value for the 0-window probes. This patch is similar to and builds on top of the one that made TCP_USER_TIMEOUT accurate for RTOs in commit |

tcp: fix TCP_USER_TIMEOUT with zero window
commit 9d9b1ee0b2d1c9e02b2338c4a4b0a062d2d3edac upstream.
The TCP session does not terminate with TCP_USER_TIMEOUT when data
remain untransmitted due to zero window.
The number of unanswered zero-window probes (tcp_probes_out) is
reset to zero with incoming acks irrespective of the window size,
as described in tcp_probe_timer():
RFC 1122 4.2.2.17 requires the sender to stay open indefinitely
as long as the receiver continues to respond probes. We support
this by default and reset icsk_probes_out with incoming ACKs.
This counter, however, is the wrong one to be used in calculating the
duration that the window remains closed and data remain untransmitted.
Thanks to Jonathan Maxwell <jmaxwell37@gmail.com> for diagnosing the
actual issue.
In this patch a new timestamp is introduced for the socket in order to
track the elapsed time for the zero-window probes that have not been
answered with any non-zero window ack.

tcp: Prevent low rmem stalls with SO_RCVLOWAT.
With SO_RCVLOWAT, under memory pressure,
it is possible to enter a state where:
1. We have not received enough bytes to satisfy SO_RCVLOWAT.
2. We have not entered buffer pressure (see tcp_rmem_pressure()).
3. But, we do not have enough buffer space to accept more packets.
In this case, we advertise 0 rwnd (due to #3) but the application does
not drain the receive queue (no wakeup because of #1 and #2) so the
flow stalls.
Modify the heuristic for SO_RCVLOWAT so that, if we are advertising
rwnd<=rcv_mss, force a wakeup to prevent a stall.
Without this patch, setting tcp_rmem to 6143 and disabling TCP
autotune causes a stalled flow. With this patch, no stall occurs. This
is with RPC-style traffic with large messages.

tcp: fix to update snd_wl1 in bulk receiver fast path
In the header prediction fast path for a bulk data receiver, if no
data is newly acknowledged then we do not call tcp_ack() and do not
call tcp_ack_update_window(). This means that a bulk receiver that
receives large amounts of data can have the incoming sequence numbers
wrap, so that the check in tcp_may_update_window fails:
after(ack_seq, tp->snd_wl1)
If the incoming receive windows are zero in this state, and then the
connection that was a bulk data receiver later wants to send data,
that connection can find itself persistently rejecting the window
updates in incoming ACKs. This means the connection can persistently
fail to discover that the receive window has opened, which in turn
means that the connection is unable to send anything, and the
connection's sending process can get permanently "stuck".
The fix is to update snd_wl1 in the header prediction fast path for a
bulk data receiver, so that it keeps up and does not see wrapping
problems.
This fix is based on a very nice and thorough analysis and diagnosis
by Apollon Oikonomopoulos (see link below).
This is a stable candidate but there is no Fixes tag here since the
bug predates current git history. Just for fun: looks like the bug
dates back to when header prediction was added in Linux v2.1.8 in Nov
1996. In that version tcp_rcv_established() was added, and the code
only updates snd_wl1 in tcp_ack(), and in the new "Bulk data transfer:
receiver" code path it does not call tcp_ack(). This fix seems to
apply cleanly at least as far back as v3.2.
