The Time-Aware Shaper (TAS) is a key feature of the Enhanced Scheduled
Traffic (EST) mechanism defined in IEEE 802.1Q-2018. This patch adds TAS
support for the ICSSG driver by interacting with the ICSSG firmware to
manage gate control lists, cycle times, and other TAS parameters.
The firmware maintains active and shadow lists. The driver updates the
operating list using API `tas_update_oper_list()` which,
- Updates firmware list pointers via `tas_update_fw_list_pointers`.
- Writes gate masks, window end times, and clears unused entries in the
shadow list.
- Updates gate close times and Max SDU values for each queue.
- Triggers list changes using `tas_set_trigger_list_change`, which
- Computes cycle count (base-time % cycle-time) and extend (base-time %
cycle-time)
- Writes cycle time, cycle count, and extend values to firmware memory.
- base-time being in past or base-time not being a multiple of
cycle-time is taken care by the firmware. Driver just writes these
variable for firmware and firmware takes care of the scheduling.
- If base-time is not a multiple of cycle-time, the value of extend
(base-time % cycle-time) is used by the firmware to extend the last
cycle.
- Sets `config_change` and `config_pending` flags to notify firmware of
the new shadow list and its readiness for activation.
- Sends the `ICSSG_EMAC_PORT_TAS_TRIGGER` r30 command to ask firmware to
swap active and shadow lists.
- Waits for the firmware to clear the `config_change` flag before
completing the update and returning successfully.
This implementation ensures seamless TAS functionality by offloading
scheduling complexities to the firmware.

mptcp_lib_get_info_value() will only print the first entry that match the filter because of the ';q' at the end. As a consequence, the 'sed' command could finish before the previous 'grep' one and print a 'write error' warning because it is trying to write data to the closed pipe. Such warnings are not interesting, they can be hidden by muting stderr here for grep. While at it, clearly indicate that mptcp_lib_get_info_value() will only print the first matched entry to avoid confusions later on.

This patch introduces the '__u32 proto' variable to the 'send_query' and 'recv_nlmsg' functions for further extending function. In the 'send_query' function, the inclusion of this variable makes the structure clearer and more readable. In the 'recv_nlmsg' function, the '__u32 proto' variable ensures that the 'diag_info' field remains unmodified when processing IPPROTO_TCP data, thereby preventing unintended transformation into 'mptcp_info' format. While at it, increment iovlen directly when an item is added to simplify this portion of the code and improve its readaility.

This patch adds 'get_subflow_info' in 'mptcp_diag', which can check whether a TCP connection is an MPTCP subflow based on the "INET_ULP_INFO_MPTCP" with tcp_diag method. The helper 'print_subflow_info' in 'mptcp_diag' can print the subflow_filed of an MPTCP subflow for further checking the 'subflow_info' through inet_diag method. The example of the whole output should be: $ ./mptcp_diag -s "127.0.0.1:10000 127.0.0.1:38984" 127.0.0.1:10000 -> 127.0.0.1:38984 It's a mptcp subflow, the subflow info: flags:Mec token:0000(id:0)/4278e77e(id:0) seq:9288466187236176036 \ sfseq:1 ssnoff:2317083055 maplen:215 Co-developed-by: Geliang Tang <[email protected]> Signed-off-by: Geliang Tang <[email protected]> Signed-off-by: Gang Yan <[email protected]> Reviewed-by: Matthieu Baerts (NGI0) <[email protected]> Signed-off-by: Matthieu Baerts (NGI0) <[email protected]> Signed-off-by: NipaLocal <nipa@local>

Use addrconf_addr_gen() to generate IPv6 link-local addresses on GRE devices in most cases and fall back to using add_v4_addrs() only in case the GRE configuration is incompatible with addrconf_addr_gen(). GRE used to use addrconf_addr_gen() until commit e5dd729 ("ip/ip6_gre: use the same logic as SIT interfaces when computing v6LL address") restricted this use to gretap and ip6gretap devices, and created add_v4_addrs() (borrowed from SIT) for non-Ethernet GRE ones. The original problem came when commit 9af2851 ("addrconf: refuse isatap eui64 for INADDR_ANY") made __ipv6_isatap_ifid() fail when its addr parameter was 0. The commit says that this would create an invalid address, however, I couldn't find any RFC saying that the generated interface identifier would be wrong. Anyway, since gre over IPv4 devices pass their local tunnel address to __ipv6_isatap_ifid(), that commit broke their IPv6 link-local address generation when the local address was unspecified. Then commit e5dd729 ("ip/ip6_gre: use the same logic as SIT interfaces when computing v6LL address") tried to fix that case by defining add_v4_addrs() and calling it to generate the IPv6 link-local address instead of using addrconf_addr_gen() (apart for gretap and ip6gretap devices, which would still use the regular addrconf_addr_gen(), since they have a MAC address). That broke several use cases because add_v4_addrs() isn't properly integrated into the rest of IPv6 Neighbor Discovery code. Several of these shortcomings have been fixed over time, but add_v4_addrs() remains broken on several aspects. In particular, it doesn't send any Router Sollicitations, so the SLAAC process doesn't start until the interface receives a Router Advertisement. Also, add_v4_addrs() mostly ignores the address generation mode of the interface (/proc/sys/net/ipv6/conf/*/addr_gen_mode), thus breaking the IN6_ADDR_GEN_MODE_RANDOM and IN6_ADDR_GEN_MODE_STABLE_PRIVACY cases. Fix the situation by using add_v4_addrs() only in the specific scenario where the normal method would fail. That is, for interfaces that have all of the following characteristics: * run over IPv4, * transport IP packets directly, not Ethernet (that is, not gretap interfaces), * tunnel endpoint is INADDR_ANY (that is, 0), * device address generation mode is EUI64. In all other cases, revert back to the regular addrconf_addr_gen(). Also, remove the special case for ip6gre interfaces in add_v4_addrs(), since ip6gre devices now always use addrconf_addr_gen() instead. Note: This patch was originally applied as commit 183185a ("gre: Fix IPv6 link-local address generation."). However, it was then reverted by commit fc486c2 ("Revert "gre: Fix IPv6 link-local address generation."") because it uncovered another bug that ended up breaking net/forwarding/ip6gre_custom_multipath_hash.sh. That other bug has now been fixed by commit 4d0ab3a ("ipv6: Start path selection from the first nexthop"). Therefore we can now revive this GRE patch (no changes since original commit 183185a ("gre: Fix IPv6 link-local address generation.").

GRE devices have their special code for IPv6 link-local address generation that has been the source of several regressions in the past. Add selftest to check that all gre, ip6gre, gretap and ip6gretap get an IPv6 link-link local address in accordance with the net.ipv6.conf.<dev>.addr_gen_mode sysctl. Note: This patch was originally applied as commit 6f50175 ("selftests: Add IPv6 link-local address generation tests for GRE devices."). However, it was then reverted by commit 355d940 ("Revert "selftests: Add IPv6 link-local address generation tests for GRE devices."") because the commit it depended on was going to be reverted. Now that the situation is resolved, we can add this selftest again (no changes since original patch, appart from context update in tools/testing/selftests/net/Makefile).

ksft runner sends 2 SIGTERMs in a row if a test runs out of time. Handle this in a similar way we handle SIGINT - cleanup and stop running further tests. Because we get 2 signals we need a bit of logic to ignore the subsequent one, they come immediately one after the other (due to commit 9616cb3 ("kselftest/runner.sh: Propagate SIGTERM to runner child")). This change makes sure we run cleanup (scheduled defer()s) and also print a stack trace on SIGTERM, which doesn't happen by default. Tests occasionally hang in NIPA and it's impossible to tell what they are waiting from or doing. Signed-off-by: Jakub Kicinski <[email protected]> Signed-off-by: NipaLocal <nipa@local>
The `get_interface_info` call has ip version hard-coded which leads to
failures on an IPV6 system. The NetDrvEnv class already gathers
information about remote interface, so instead of fixing the local
implementation switch to using cfg.remote_ifname.
