skb->truesize is not meant to be tracking amount of used bytes in a skb, but amount of reserved/consumed bytes in memory. For instance, if we use a single byte in last page fragment, we have to account the full size of the fragment. So skb_add_rx_frag needs to calculate the length of the entire buffer into turesize.

Kevin Yang says: ==================== tcp_bbr: PROBE_RTT minor bug fixes This series includes two minor bug fixes for the TCP BBR PROBE_RTT mechanism, and one preparatory patch: (1) A preparatory patch to reorganize the PROBE_RTT logic by refactoring (into its own function) the code to exit PROBE_RTT, since the next patch will be using that code in a new context. (2) Fix: When BBR restarts from idle and if BBR is in PROBE_RTT mode, BBR should check if it's time to exit PROBE_RTT. If yes, then BBR should exit PROBE_RTT mode and restore the cwnd to its full value. (3) Fix: Apply the PROBE_RTT cwnd cap even if the count of fully-ACKed packets is 0. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

由 Kevin Yang 提交于
This commit fixes a corner case where TCP BBR would enter PROBE_RTT mode but not reduce its cwnd. If a TCP receiver ACKed less than one full segment, the number of delivered/acked packets was 0, so that bbr_set_cwnd() would short-circuit and exit early, without cutting cwnd to the value we want for PROBE_RTT. The fix is to instead make sure that even when 0 full packets are ACKed, we do apply all the appropriate caps, including the cap that applies in PROBE_RTT mode.

tcp uses per-cpu (and per namespace) sockets (net->ipv4.tcp_sk) internally to send some control packets. 1) RST packets, through tcp_v4_send_reset() 2) ACK packets in SYN-RECV and TIME-WAIT state, through tcp_v4_send_ack() These packets assert IP_DF, and also use the hashed IP ident generator to provide an IPv4 ID number. Geoff Alexander reported this could be used to build off-path attacks. These packets should not be fragmented, since their size is smaller than IPV4_MIN_MTU. Only some tunneled paths could eventually have to fragment, regardless of inner IPID. We really can use zero IPID, to address the flaw, and as a bonus, avoid a couple of atomic operations in ip_idents_reserve() Signed-off-by: NEric Dumazet <edumazet@google.com> Reported-by: NGeoff Alexander <alexandg@cs.unm.edu> Tested-by: NGeoff Alexander <alexandg@cs.unm.edu> Signed-off-by: NDavid S.

The TC filter flow mapping override completely skipped the call to cake_hash(); however that meant that the internal state was not being updated, which ultimately leads to deadlocks in some configurations. Fix that by passing the overridden flow ID into cake_hash() instead so it can react appropriately. In addition, the major number of the class ID can now be set to override the host mapping in host isolation mode. If both host and flow are overridden (or if the respective modes are disabled), flow dissection and hashing will be skipped entirely; otherwise, the hashing will be kept for the portions that are not set by the filter.

use_all_metadata() acquires read_lock(&ife_mod_lock), then calls add_metainfo() which calls find_ife_oplist() which acquires the same lock again. Deadlock! Introduce __add_metainfo() which accepts struct tcf_meta_ops *ops as an additional parameter and let its callers to decide how to find it. For use_all_metadata(), it already has ops, no need to find it again, just call __add_metainfo() directly. And, as ife_mod_lock is only needed for find_ife_oplist(), this means we can make non-atomic allocation for populate_metalist() now.

tcf_action_put_many() is mostly called to clean up actions on failure path, but tcf_action_put_many(&actions[acts_deleted]) is used in the ugliest way: it passes a slice of the array and uses an additional NULL at the end to avoid out-of-bound access. acts_deleted is completely unnecessary since we can teach tcf_action_put_many() scan the whole array and checks against NULL pointer. Which also means tcf_action_delete() should set deleted action pointers to NULL to avoid double free.
