Structure 'tls_rec' contains sg_aead_in and sg_aead_out which point to a aad_space and then chain scatterlists sg_plaintext_data, sg_encrypted_data respectively. Rather than using chained scatterlists for plaintext and encrypted data in aead_req, it is efficient to store aad_space in sg_encrypted_data and sg_plaintext_data itself in the first index and get rid of sg_aead_in, sg_aead_in and further chaining. This requires increasing size of sg_encrypted_data & sg_plaintext_data arrarys by 1 to accommodate entry for aad_space. The code which uses sg_encrypted_data and sg_plaintext_data has been modified to skip first index as it points to aad_space. Signed-off-by:

Jon Maloy says: ==================== tipc: make connection setup more robust In this series we make a few improvements to the connection setup and probing mechanism, culminating in the last commit where we make it possible for a client socket to make multiple setup attempts in case it encounters receive buffer overflow at the listener socket. ==================== Signed-off-by: -
Tung Nguyen authored
Default socket receive buffer size for a listener socket is 2Mb. For each arriving empty SYN, the linux kernel allocates a 768 bytes buffer. This means that a listener socket can serve maximum 2700 simultaneous empty connection setup requests before it hits a receive buffer overflow, and much fewer if the SYN is carrying any significant amount of data. When this happens the setup request is rejected, and the client receives an ECONNREFUSED error. This commit mitigates this problem by letting the client socket try to retransmit the SYN message multiple times when it sees it rejected with the code TIPC_ERR_OVERLOAD. Retransmission is done at random intervals in the range of [100 ms, setup_timeout / 4], as many times as there is room for within the setup timeout limit. Signed-off-by:

Messages intended for intitating a connection are currently indistinguishable from regular datagram messages. The TIPC protocol specification defines bit 17 in word 0 as a SYN bit to allow sanity check of such messages in the listening socket, but this has so far never been implemented. We do that in this commit. Acked-by:

The function tipc_msg_reverse() is reversing the header of a message while reusing the original buffer. We have seen at several occasions that this may have unfortunate side effects when the buffer to be reversed is a clone. In one of the following commits we will again need to reverse cloned buffers, so this is the right time to permanently eliminate this problem. In this commit we let the said function always consume the original buffer and replace it with a new one when applicable. Acked-by:

Previously TCP initial receive buffer is ~87KB by default and the initial receive window is ~29KB (20 MSS). This patch changes the two numbers to 128KB and ~64KB (rounding down to the multiples of MSS) respectively. The patch also simplifies the calculations s.t. the two numbers are directly controlled by sysctl tcp_rmem[1]: 1) Initial receiver buffer budget (sk_rcvbuf): while this should be configured via sysctl tcp_rmem[1], previously tcp_fixup_rcvbuf() always override and set a larger size when a new connection establishes. 2) Initial receive window in SYN: previously it is set to 20 packets if MSS <= 1460. The number 20 was based on the initial congestion window of 10: the receiver needs twice amount to avoid being limited by the receive window upon out-of-order delivery in the first window burst. But since this only applies if the receiving MSS <= 1460, connection using large MTU (e.g. to utilize receiver zero-copy) may be limited by the receive window. With this patch TCP memory configuration is more straight-forward and more properly sized to modern high-speed networks by default. Several popular stacks have been announcing 64KB rwin in SYNs as well. Signed-off-by:Yuchung Cheng <ycheng@google.com> Signed-off-by:

Jeff Kirsher says: ==================== 100GbE Intel Wired LAN Driver Updates 2018-09-27 This series contains fixes to the ice driver only. Jake fixes a potential crash due to attempting to access the mutex which is already destroyed. Fix this by using rq.count and sq.count to determine if the queue was initialized. Fixed the current logic for checking the firmware version to properly handle situations when firmware major/minor versions differ and when the branch version differs. Bruce replaces a memcpy() with a direct assignment, which is preferred. Also updated the branding strings and device ids supported by the driver. Fixed the "ethtool -G" command in the driver, which was always returning EINVAL when changing the descriptor ring size. Brett update and clarified code comments. Anirudh updates the driver to ensure we query the firmware for the transmit scheduler node information before adding it to the driver database, to ensure we have the current information. Also update the "get capabilities" command to get device and function capabilities. ==================== Signed-off-by: -

Johannes Berg says: ==================== netlink: nested policy validation This adds nested policy validation, which lets you specify the nested attribute type, e.g. NLA_NESTED with sub-policy, or the new NLA_NESTED_ARRAY with sub-sub-policy. Changes in v2: * move setting the bad attr pointer/message into validate_nla() * remove the recursion patch since that's no longer needed * simply skip the generic bad attr pointer/message setting in case of nested nla_validate() failing since that could fail only due to validate_nla() failing inside, which already sets the extack information Changes in v3: * fix NLA_REJECT to have an error message if none is in policy ==================== Signed-off-by: -

Sometimes nested netlink attributes are just used as arrays, with the nla_type() of each not being used; we have this in nl80211 and e.g. NFTA_SET_ELEM_LIST_ELEMENTS. Add the ability to validate this type of message directly in the policy, by adding the type NLA_NESTED_ARRAY which does exactly this: require a first level of nesting but ignore the attribute type, and then inside each require a second level of nested and validate those attributes against a given policy (if present). Note that some nested array types actually require that all of the entries have the same index, this is possible to express in a nested policy already, apart from the validation that only the one allowed type is used.

Now that we have a validation_data pointer, and the len field in the policy is unused for NLA_NESTED, we can allow using them both to have nested validation. This can be nice in code, although we still have to use nla_parse_nested() or similar which would also take a policy; however, it also serves as documentation in the policy without requiring a look at the code.
