2019-11-08sctp: add support for Primary Path SwitchoverXin Long1-0/+12
This is a new feature defined in section 5 of rfc7829: "Primary Path Switchover". By introducing a new tunable parameter: Primary.Switchover.Max.Retrans (PSMR) The primary path will be changed to another active path when the path error counter on the old primary path exceeds PSMR, so that "the SCTP sender is allowed to continue data transmission on a new working path even when the old primary destination address becomes active again". This patch is to add this tunable parameter, 'ps_retrans' per netns, sock, asoc and transport. It also allows a user to change ps_retrans per netns by sysctl, and ps_retrans per sock/asoc/transport will be initialized with it. The check will be done in sctp_do_8_2_transport_strike() when this feature is enabled. Note this feature is disabled by initializing 'ps_retrans' per netns as 0xffff by default, and its value can't be less than 'pf_retrans' when changing by sysctl. v3->v4: - add define SCTP_PS_RETRANS_MAX 0xffff, and use it on extra2 of sysctl 'ps_retrans'. - add a new entry for ps_retrans on ip-sysctl.txt.

2019-11-08sctp: add pf_expose per netns and sock and asocXin Long1-0/+22
As said in rfc7829, section 3, point 12: The SCTP stack SHOULD expose the PF state of its destination addresses to the ULP as well as provide the means to notify the ULP of state transitions of its destination addresses from active to PF, and vice versa. However, it is recommended that an SCTP stack implementing SCTP-PF also allows for the ULP to be kept ignorant of the PF state of its destinations and the associated state transitions, thus allowing for retention of the simpler state transition model of [RFC4960] in the ULP. Not only does it allow to expose the PF state to ULP, but also allow to ignore sctp-pf to ULP. So this patch is to add pf_expose per netns, sock and asoc. And in sctp_assoc_control_transport(), ulp_notify will be set to false if asoc->expose is not 'enabled' in next patch. It also allows a user to change pf_expose per netns by sysctl, and pf_expose per sock and asoc will be initialized with it. Note that pf_expose also works for SCTP_GET_PEER_ADDR_INFO sockopt, to not allow a user to query the state of a sctp-pf peer address when pf_expose is 'disabled', as said in section 7.3. v1->v2: - Fix a build warning noticed by Nathan Chancellor. v2->v3: - set pf_expose to UNUSED by default to keep compatible with old applications. v3->v4: - add a new entry for pf_expose on ip-sysctl.txt, as Marcelo suggested. - change this patch to 1/5, and move sctp_assoc_control_transport change into 2/5, as Marcelo suggested. - use SCTP_PF_EXPOSE_UNSET instead of SCTP_PF_EXPOSE_UNUSED, and set SCTP_PF_EXPOSE_UNSET to 0 in enum, as Marcelo suggested.

atlantic hardware does support UDP hardware segmentation offload. This allows user to specify one large contiguous buffer with data which then will be split automagically into multiple UDP packets of specified size. Bulk sending of large UDP streams lowers CPU usage and increases bandwidth. We did estimations both with udpgso_bench_tx test tool and with modified iperf3 measurement tool (4 streams, multithread, 200b packet size) over AQC<->AQC 10G link.

Add layer 3 generic packet exception traps that can report trapped packets and documentation of the traps. Unlike drop traps, these exception traps also need to inject the packet to the kernel's receive path. For example, a packet that was trapped due to unreachable neighbour need to be injected into the kernel so that it will trigger an ARP request or a neighbour solicitation message.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2019-11-01 This series contains updates to e1000, igb, igc, ixgbe, i40e and driver documentation. Lyude Paul fixes an issue where a fatal read error occurs when the device is unplugged from the machine. So change the read error into a warn while the device is still present. Manfred Rudigier found that the i350 device was not apart of the "Media Auto Sense" feature, yet the device supports it. So add the missing i350 device to the check and fix an issue where the media auto sense would flip/flop when no cable was connected to the port causing spurious kernel log messages. I fixed an issue where the fix to resolve receive buffer starvation was applied in more than one place in the driver, one being the incorrect location in the i40e driver. Wenwen Wang fixes a potential memory leak in e1000 where allocated memory is not properly cleaned up in one of the error paths. Jonathan Neuschäfer cleans up the driver documentation to be consistent and remove the footnote reference, since the footnote no longer exists in the documentation. Igor Pylypiv cleans up a duplicate clearing of a bit, no need to clear it twice. v2: Fixed alignment issue in patch 3 of the series based on community feedback. ==================== Signed-off-by: David S.

2019-10-31net: increase SOMAXCONN to 4096Eric Dumazet1-2/+2
SOMAXCONN is /proc/sys/net/core/somaxconn default value. It has been defined as 128 more than 20 years ago. Since it caps the listen() backlog values, the very small value has caused numerous problems over the years, and many people had to raise it on their hosts after beeing hit by problems. Google has been using 1024 for at least 15 years, and we increased this to 4096 after TCP listener rework has been completed, more than 4 years ago. We got no complain of this change breaking any legacy application. Many applications indeed setup a TCP listener with listen(fd, -1); meaning they let the system select the backlog. Raising SOMAXCONN lowers chance of the port being unavailable under even small SYNFLOOD attack, and reduces possibilities of side channel vulnerabilities.

2019-10-14mm, page_owner: decouple freeing stack trace from debug_pageallocVlastimil Babka1-0/+3
Commit 8974558f49a6 ("mm, page_owner, debug_pagealloc: save and dump freeing stack trace") enhanced page_owner to also store freeing stack trace, when debug_pagealloc is also enabled. KASAN would also like to do this [1] to improve error reports to debug e.g. UAF issues. Kirill has suggested that the freeing stack trace saving should be also possible to be enabled separately from KASAN or debug_pagealloc, i.e. with an extra boot option. Qian argued that we have enough options already, and avoiding the extra overhead is not worth the complications in the case of a debugging option. Kirill noted that the extra stack handle in struct page_owner requires 0.1% of memory. This patch therefore enables free stack saving whenever page_owner is enabled, regardless of whether debug_pagealloc or KASAN is also enabled. KASAN kernels booted with page_owner=on will thus benefit from the improved error reports.
