When IGC is built-in but LEDS_CLASS is a loadable module, there is a link failure: x86_64-linux-ld: drivers/net/ethernet/intel/igc/igc_leds.o: in function `igc_led_setup': igc_leds.c:(.text+0x75c): undefined reference to `devm_led_classdev_register_ext' Add another dependency that prevents this combination.

Added support for 1000BASE-BX, i.e. Gigabit Ethernet over single strand of single-mode fiber. The initialization of a 1000BASE-BX SFP is the same as 1000BASE-SX/LX with the only difference that the Bit Rate Nominal Value must be checked to make sure it is a Gigabit Ethernet transceiver, as described by the SFF-8472 specification.

Linux users sometimes need an easy way to check current values of module parameters. For example the module may be manually reloaded with different parameters. Make these visible and readable in the /sys filesystem to allow that. But don't make the "debug" module parameter visible as debugging is enabled via ethtool msglvl. Signed-off-by:

Matthieu Baerts says: ==================== mptcp: userspace pm: 'dump addrs' and 'get addr' This series from Geliang adds two new Netlink commands to the userspace PM: - one to dump all addresses of a specific MPTCP connection: - feature added in patches 3 to 5 - test added in patches 7, 8 and 10 - and one to get a specific address for an MPTCP connection: - feature added in patches 11 to 13 - test added in patches 14 and 15 These new Netlink commands can be useful if an MPTCP daemon lost track of the different connections, e.g. after having been restarted. The other patches are some clean-ups and small improvements added while working on the new features. ==================== Signed-off-by:Matthieu Baerts (NGI0) <matttbe@kernel.org>

This patch adds the address flag MPTCP_PM_ADDR_FLAG_SUBFLOW in csf() in pm_nl_ctl.c when subflow is created by a userspace PM. Signed-off-by:
-
Geliang Tang authored
Just like MPTCP_PM_ADDR_FLAG_SIGNAL flag is checked in userspace PM announce mptcp_pm_nl_announce_doit(), PM flags should be checked in mptcp_pm_nl_subflow_create_doit() too. If MPTCP_PM_ADDR_FLAG_SUBFLOW flag is not set, there's no flags field in the output of dump_addr. This looks a bit strange: id 10 flags 10.0.3.2 This patch uses mptcp_pm_parse_entry() instead of mptcp_pm_parse_addr() to get the PM flags of the entry and check it. MPTCP_PM_ADDR_FLAG_SIGNAL flag shouldn't be set here, and if MPTCP_PM_ADDR_FLAG_SUBFLOW flag is missing from the netlink attribute, always set this flag. Signed-off-by: -

Alex Elder says: ==================== net: ipa: simplify device pointer access This version of this patch series fixes the bugs in the first patch (which were fixed in the second), where ipa_interrupt_config() had two remaining spots that returned a pointer rather than an integer. Outside of initialization, all uses of the platform device pointer stored in the IPA structure determine the address of device structure embedded within the platform device structure. By changing some of the initialization functions to take a platform device as argument we can simplify getting at the device structure address by storing it (instead of the platform device pointer) in the IPA structure. The first two patches split the interrupt initialization code into two parts--one done earlier than before. The next four patches update some initialization functions to take a platform device pointer as argument. And the last patch replaces the platform device pointer with a device pointer, and converts all remaining references to the &ipa->pdev->dev to use ipa->dev. ==================== Signed-off-by: -

Create a new function ipa_interrupt_init() that is called at probe time to allocate and initialize the IPA interrupt data structure. Create ipa_interrupt_exit() as its inverse.

Matthieu Baerts says: ==================== mptcp: add TCP_NOTSENT_LOWAT sockopt support Patch 3 does the magic of adding TCP_NOTSENT_LOWAT support, all the other ones are minor cleanup seen along when working on the new feature. Note that this feature relies on the existing accounting for snd_nxt. Such accounting is not 110% accurate as it tracks the most recent sequence number queued to any subflow, and not the actual sequence number sent on the wire. Paolo experimented a lot, trying to implement the latter, and in the end it proved to be both "too complex" and "not necessary". The complexity raises from the need for additional lock and a lot of refactoring to introduce such protections without adding significant overhead. Additionally, snd_nxt is currently used and exposed with the current semantic by the internal packet scheduling. Introducing a different tracking will still require us to keep the old one. More interestingly, a more accurate tracking could be not strictly necessary: as the MPTCP socket enqueues data to the subflows only up to the available send window, any enqueue data is sent on the wire instantly, without any blocking operation short or a drop in the tx path at the nft or TC layer. ==================== Signed-off-by: -

Add support for such socket option storing the user-space provided value in a new msk field, and using such data to implement the _mptcp_stream_memory_free() helper, similar to the TCP one. To avoid adding more indirect calls in the fast path, open-code a variant of sk_stream_memory_free() in mptcp_sendmsg() and add direct calls to the mptcp stream memory free helper where possible.

With commit 34d21de9 ("net: Move {l,t,d}stats allocation to core and convert veth & vrf"), stats allocation could be done on net core instead of this driver. With this new approach, the driver doesn't have to bother with error handling (allocation failure checking, making sure free happens in the right spot, etc). This is core responsibility now. Remove the allocation in the nlmon driver and leverage the network core allocation. Signed-off-by:
