This also replaces spots that used for_primary_ifa(). for_primary_ifa() aborts the loop on the first secondary address seen. Replace it with either the rcu or rtnl variant of in_dev_for_each_ifa(), but two places will now also consider secondary addresses too: inet_addr_onlink() and inet_ifa_byprefix(). I do not understand why they should ignore secondary addresses. Why would a secondary address not be considered 'on link'? When matching a prefix, why ignore a matching secondary address? Other places get converted as well, but gain "->flags & SECONDARY" check. Signed-off-by:

The ifa_list is protected either by rcu or rtnl lock, but the current iterators do not account for this. This adds two iterators as replacement, a later patch in the series will update them with the needed rcu/rtnl_dereference calls. Its not done in this patch yet to avoid sparse warnings -- the fields lack the proper __rcu annotation. Signed-off-by:

David Howells says: I'm told that there's not really any point populating the list. Current OpenAFS ignores it, as does AuriStor - and IBM AFS 3.6 will do the right thing. The list is actually useless as it's the client's view of the world, not the servers, so if there's any NAT in the way its contents are invalid. Further, it doesn't support IPv6 addresses. On that basis, feel free to make it an empty list and remove all the interface enumeration. V1 of this patch reworked the function to use a new helper for the ifa_list iteration to avoid sparse warnings once the proper __rcu annotations get added in struct in_device later. But, in light of the above, just remove afs_get_ipv4_interfaces. Compile tested only. Cc: David Howells <dhowells@redhat.com> Cc: linux-afs@lists.infradead.org Signed-off-by:

Arnd Bergmann says: ==================== isdn: deprecate non-mISDN drivers When isdn4linux came up in the context of another patch series, I remembered that we had discussed removing it a while ago. It turns out that the suggestion from Karsten Keil wa to remove I4L in 2018 after the last public ISDN networks are shut down. This has happened now (with a very small number of exceptions), so I guess it's time to try again. We currently have three ISDN stacks in the kernel: the original isdn4linux (with the hisax driver), the newer CAPI (with four drivers), and finally the mISDN stack (supporting roughly the same hardware as hisax). As far as I can tell, anyone using ISDN with mainline kernel drivers in the past few years uses mISDN, and this is typically used for voice-only PBX installations that don't require a public network. The older stacks support additional features for data networks, but those typically make no sense any more if there is no network to connect to. My proposal for this time is to kill off isdn4linux entirely, as it seems to have been unusable for quite a while. This code has been abandoned for many years and it does cause problems for treewide maintenance as it tends to do everything that we try to stop doing. Birger Harzenetter mentioned that is is still using i4l in order to make use of the 'divert' feature that is not part of mISDN, but has otherwise moved on to mISDN for normal operation, like apparently everyone else. CAPI in turn is not quite as obsolete, but two of the drivers (avm and hysdn) don't seem to be used at all, while another one (gigaset) will stop being maintained as Paul Bolle is no longer able to test it after the network gets shut down in September. All three are now moved into drivers/staging to let others speak up in case there are remaining users. This leaves Bluetooth CMTP as the only remaining user of CAPI, but Marcel Holtmann wishes to keep maintaining it. For the discussion on version 1, see [2] Unfortunately, Karsten Keil as the maintainer has not participated in the discussion.

If run in client mode (the default), it will add a map entry keyed by the target IP address; this map will store RTT measurements, current sequence number etc. Finally in client mode the ping command is executed, and the xdping BPF program will use the last ICMP reply, reformulate it as an ICMP request with the next sequence number and XDP_TX it. After the reply to that request is received we can measure RTT and repeat until the desired number of measurements is made. This is why the sequence numbers in the normal ping are 1, 2, 3 and 8. We XDP_TX a modified version of ICMP reply 4 and keep doing this until we get the 4 replies we need; hence the networking stack only sees reply 8, where we have XDP_PASSed it upstream since we are done. In server mode (-s), xdping simply takes ICMP requests and replies to them in XDP rather than passing the request up to the networking stack. No map entry is required. xdping can be run in native XDP mode (the default, or specified via -N) or in skb mode (-S). A test program test_xdping.sh exercises some of these options. Note that native XDP does not seem to XDP_TX for veths, hence -N is not tested. Looking at the code, it looks like XDP_TX is supported so I'm not sure if that's expected. Running xdping in native mode for ixgbe as both client and server works fine. Changes since v4 - close fds on cleanup (Song Liu) Changes since v3 - fixed seq to be __be16 (Song Liu) - fixed fd checks in xdping.c (Song Liu) Changes since v2 - updated commit message to explain why seq number of last ICMP reply is 8 not 4 (Song Liu) - updated types of seq number, raddr and eliminated csum variable in xdpclient/xdpserver functions as it was not needed (Song Liu) - added XDPING_DEFAULT_COUNT definition and usage specification of default/max counts (Song Liu) Changes since v1 - moved from RFC to PATCH - removed unused variable in ipv4_csum() (Song Liu) - refactored ICMP checks into icmp_check() function called by client and server programs and reworked client and server programs due to lack of shared code (Song Liu) - added checks to ensure that SKB and native mode are not requested together (Song Liu) Signed-off-by:

Roman Gushchin says: ==================== During my work on memcg-based memory accounting for bpf maps I've done some cleanups and refactorings of the existing memlock rlimit-based code. It makes it more robust, unifies size to pages conversion, size checks and corresponding error codes. Also it adds coverage for cgroup local storage and socket local storage maps. It looks like some preliminary work on the mm side might be required to start working on the memcg-based accounting, so I'm sending these patches as a separate patchset. ==================== Signed-off-by: -

Roman Gushchin authored
In order to unify the existing memlock charging code with the memcg-based memory accounting, which will be added later, let's rework the current scheme. Currently the following design is used: 1) .alloc() callback optionally checks if the allocation will likely succeed using bpf_map_precharge_memlock() 2) .alloc() performs actual allocations 3) .alloc() callback calculates map cost and sets map.memory.pages 4) map_create() calls bpf_map_init_memlock() which sets map.memory.user and performs actual charging; in case of failure the map is destroyed <map is in use> 1) bpf_map_free_deferred() calls bpf_map_release_memlock(), which performs uncharge and releases the user 2) .map_free() callback releases the memory The scheme can be simplified and made more robust: 1) .alloc() calculates map cost and calls bpf_map_charge_init() 2) bpf_map_charge_init() sets map.memory.user and performs actual charge 3) .alloc() performs actual allocations <map is in use> 1) .map_free() callback releases the memory 2) bpf_map_charge_finish() performs uncharge and releases the user The new scheme also allows to reuse bpf_map_charge_init()/finish() functions for memcg-based accounting. Because charges are performed before actual allocations and uncharges after freeing the memory, no bogus memory pressure can be created. In cases when the map structure is not available (e.g. it's not created yet, or is already destroyed), on-stack bpf_map_memory structure is used. The charge can be transferred with the bpf_map_charge_move() function. Signed-off-by: -

Group "user" and "pages" fields of bpf_map into the bpf_map_memory structure. Later it can be extended with "memcg" and other related information. The main reason for a such change (beside cosmetics) is to pass bpf_map_memory structure to charging functions before the actual allocation of bpf_map. Signed-off-by:

Lawrence Brakmo says: ==================== This patchset adds support for propagating congestion notifications (cn) to TCP from cgroup inet skb egress BPF programs. Current cgroup skb BPF programs cannot trigger TCP congestion window reductions, even when they drop a packet. This patch-set adds support for cgroup skb BPF programs to send congestion notifications in the return value when the packets are TCP packets. Rather than the current 1 for keeping the packet and 0 for dropping it, they can now return: NET_XMIT_SUCCESS (0) - continue with packet output NET_XMIT_DROP (1) - drop packet and do cn NET_XMIT_CN (2) - continue with packet output and do cn -EPERM - drop packet Finally, HBM programs are modified to collect and return more statistics. There has been some discussion regarding the best place to manage bandwidths. Some believe this should be done in the qdisc where it can also be managed with a BPF program. We believe there are advantages for doing it with a BPF program in the cgroup/skb callback. For example, it reduces overheads in the cases where there is on primary workload and one or more secondary workloads, where each workload is running on its own cgroupv2. In this scenario, we only need to throttle the secondary workloads and there is no overhead for the primary workload since there will be no BPF program attached to its cgroup. Regardless, we agree that this mechanism should not penalize those that are not using it. We tested this by doing 1 byte req/reply RPCs over loopback. Each test consists of 30 sec of back-to-back 1 byte RPCs. Each test was repeated 50 times with a 1 minute delay between each set of 10. We then calculated the average RPCs/sec over the 50 tests. We compare upstream with upstream + patchset and no BPF program as well as upstream + patchset and a BPF program that just returns ALLOW_PKT. Here are the results: upstream 80937 RPCs/sec upstream + patches, no BPF program 80894 RPCs/sec upstream + patches, BPF program 80634 RPCs/sec These numbers indicate that there is no penalty for these patches The use of congestion notifications improves the performance of HBM when using Cubic. Without congestion notifications, Cubic will not decrease its cwnd and HBM will need to drop a large percentage of the packets. The following results are obtained for rate limits of 1Gbps, between two servers using netperf, and only one flow. We also show how reducing the max delayed ACK timer can improve the performance when using Cubic. Command used was: ./do_hbm_test.sh -l -D --stats -N -r=<rate> [--no_cn] [dctcp] \ -s=<server running netserver> where: <rate> is 1000 --no_cn specifies no cwr notifications dctcp uses dctcp Cubic DCTCP Lim, DA Mbps cwnd cred drops Mbps cwnd cred drops -------- ---- ---- ---- ----- ---- ---- ---- ----- 1G, 40 35 462 -320 67% 995 1 -212 0.05% 1G, 40,cn 736 9 -78 0.07 995 1 -212 0.05 1G, 5,cn 941 2 -189 0.13 995 1 -212 0.05 Notes: --no_cn has no effect with DCTCP Lim = rate limit DA = maximum delay ack timer cred = credit in packets drops = % packets dropped v1->v2: Insures that only BPF_CGROUP_INET_EGRESS can return values 2 and 3 New egress values apply to all protocols, not just TCP Cleaned up patch 4, Update BPF_CGROUP_RUN_PROG_INET_EGRESS callers Removed changes to __tcp_transmit_skb (patch 5), no longer needed Removed sample use of EDT v2->v3: Removed the probe timer related changes v3->v4: Replaced preempt_enable_no_resched() by preempt_enable() in BPF_PROG_CGROUP_INET_EGRESS_RUN_ARRAY() macro ==================== Acked-by:Martin KaFai Lau <kafai@fb.com> Signed-off-by:

For egress packets, this function can return: NET_XMIT_SUCCESS (0) - continue with packet output NET_XMIT_DROP (1) - drop packet and notify TCP to call cwr NET_XMIT_CN (2) - continue with packet output and notify TCP to call cwr -EPERM - drop packet For ingress packets, this function will return -EPERM if any attached program was found and if it returned != 1 during execution.

Allows cgroup inet skb programs to return values in the range [0, 3]. The second bit is used to deterine if congestion occurred and higher level protocol should decrease rate. E.g. TCP would call tcp_enter_cwr() The bpf_prog must set expected_attach_type to BPF_CGROUP_INET_EGRESS at load time if it uses the new return values (i.e. 2 or 3). The expected_attach_type is currently not enforced for BPF_PROG_TYPE_CGROUP_SKB. e.g Meaning the current bpf_prog with expected_attach_type setting to BPF_CGROUP_INET_EGRESS can attach to BPF_CGROUP_INET_INGRESS. Blindly enforcing expected_attach_type will break backward compatibility. This patch adds a enforce_expected_attach_type bit to only enforce the expected_attach_type when it uses the new return value. Signed-off-by:

Create new macro BPF_PROG_CGROUP_INET_EGRESS_RUN_ARRAY() to be used by __cgroup_bpf_run_filter_skb for EGRESS BPF progs so BPF programs can request cwr for TCP packets. Current cgroup skb programs can only return 0 or 1 (0 to drop the packet. This macro changes the behavior so the low order bit indicates whether the packet should be dropped (0) or not (1) and the next bit is used for congestion notification (cn). Hence, new allowed return values of CGROUP EGRESS BPF programs are: 0: drop packet 1: keep packet 2: drop packet and call cwr 3: keep packet and call cwr This macro then converts it to one of NET_XMIT values or -EPERM that has the effect of dropping the packet with no cn. 0: NET_XMIT_SUCCESS skb should be transmitted (no cn) 1: NET_XMIT_DROP skb should be dropped and cwr called 2: NET_XMIT_CN skb should be transmitted and cwr called 3: -EPERM skb should be dropped (no cn) Note that when more than one BPF program is called, the packet is dropped if at least one of programs requests it be dropped, and there is cn if at least one program returns cn.

Russell King says: ==================== phylink/sfp updates This is a series of updates to phylink and sfp: - Remove an unused net device argument from the phylink MII ioctl emulation code. - add support for using interrupts when using a GPIO for link status tracking, rather than polling it at one second intervals. This reduces the need to wakeup the CPU every second. - add support to the MII ioctl API to read and write Clause 45 PHY registers. I don't know how desirable this is for mainline, but I have used this facility extensively to investigate the Marvell 88x3310 PHY. A recent illustration of use for this was debugging the PHY-without-firmware problem recently reported. - add mandatory attach/detach methods for the upstream side of sfp bus code, which will allow us to remove the "netdev" structure from the SFP layers. - remove the "netdev" structure from the SFP upstream registration calls, which simplifies PHY to SFP links. ==================== Signed-off-by: -
