2024-10-09Merge wireless-next into staging-nextGreg Kroah-Hartman25-289/+140
This merges up to commit a0efa2f362a6 ("Merge net-next/main to resolve conflicts") from wireless-next into the staging-next branch to handle the removal of a staging driver easier (it happened in the wireless-next branch). That way we don't have developers confused and start submitting changes for this driver that is now deleted. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2024-10-08rtnetlink: Add assertion helpers for per-netns RTNL.Kuniyuki Iwashima1-4/+41
Once an RTNL scope is converted with rtnl_net_lock(), we will replace RTNL helper functions inside the scope with the following per-netns alternatives: ASSERT_RTNL() -> ASSERT_RTNL_NET(net) rcu_dereference_rtnl(p) -> rcu_dereference_rtnl_net(net, p) Note that the per-netns helpers are equivalent to the conventional helpers unless CONFIG_DEBUG_NET_SMALL_RTNL is enabled.

2024-10-08rtnetlink: Add per-netns RTNL.Kuniyuki Iwashima2-0/+25
The goal is to break RTNL down into per-netns mutex. This patch adds per-netns mutex and its helper functions, rtnl_net_lock() and rtnl_net_unlock(). rtnl_net_lock() acquires the global RTNL and per-netns RTNL mutex, and rtnl_net_unlock() releases them. We will replace 800+ rtnl_lock() with rtnl_net_lock() and finally removes rtnl_lock() in rtnl_net_lock(). When we need to nest per-netns RTNL mutex, we will use __rtnl_net_lock(), and its locking order is defined by rtnl_net_lock_cmp_fn() as follows: 1. init_net is first 2. netns address ascending order Note that the conversion will be done under CONFIG_DEBUG_NET_SMALL_RTNL with LOCKDEP so that we can carefully add the extra mutex without slowing down RTNL operations during conversion.

2024-10-05net_sched: sch_fq: add the ability to offload pacingJeffrey Ji1-0/+2
Some network devices have the ability to offload EDT (Earliest Departure Time) which is the model used for TCP pacing and FQ packet scheduler. Some of them implement the timing wheel mechanism described in https://saeed.github.io/files/carousel-sigcomm17.pdf with an associated 'timing wheel horizon'. This patchs adds to FQ packet scheduler TCA_FQ_OFFLOAD_HORIZON attribute. Its value is capped by the device max_pacing_offload_horizon, added in the prior patch. It allows FQ to let packets within pacing offload horizon to be delivered to the device, which will handle the needed delay without host involvement.

2024-10-05tcp: add a fast path in tcp_delack_timer()Eric Dumazet1-2/+3
delack timer is not stopped from inet_csk_clear_xmit_timer() because we do not define INET_CSK_CLEAR_TIMERS. This is a conscious choice : inet_csk_clear_xmit_timer() is often called from another cpu. Calling del_timer() would cause false sharing and lock contention. This means that very often, tcp_delack_timer() is called at the timer expiration, while there is no ACK to transmit. This can be detected very early, avoiding the socket spinlock. Notes: - test about tp->compressed_ack is racy, but in the unlikely case there is a race, the dedicated compressed_ack_timer hrtimer would close it. - Even if the fast path is not taken, reading icsk->icsk_ack.pending and tp->compressed_ack before acquiring the socket spinlock reduces acquisition time and chances of contention.

2024-10-04net_tstamp: add SCM_TS_OPT_ID to provide OPT_ID in control messageVadim Fedorenko3-1/+12
SOF_TIMESTAMPING_OPT_ID socket option flag gives a way to correlate TX timestamps and packets sent via socket. Unfortunately, there is no way to reliably predict socket timestamp ID value in case of error returned by sendmsg. For UDP sockets it's impossible because of lockless nature of UDP transmit, several threads may send packets in parallel. In case of RAW sockets MSG_MORE option makes things complicated. More details are in the conversation [1]. This patch adds new control message type to give user-space software an opportunity to control the mapping between packets and values by providing ID with each sendmsg for UDP sockets. The documentation is also added in this patch.

We just need to remove the inet_dscp_to_dsfield() conversion. * ipvlan_l3_rcv(), bpf_lwt_input_reroute(), ip_expire(), ip_rcv_finish_core(), xfrm4_rcv_encap_finish() and xfrm4_rcv_encap(), which get the DSCP directly from IPv4 headers and can simply use the ip4h_dscp() helper. While there, declare the IPv4 header pointers as const in ipvlan_l3_rcv() and bpf_lwt_input_reroute(). Also, modify the declaration of ip_route_input_noref() in include/net/route.h so that it matches the prototype of its implementation in net/ipv4/route.c.

2024-10-04ipv4: Convert ip_route_input() to dscp_t.Guillaume Nault2-2/+8
Pass a dscp_t variable to ip_route_input(), instead of a plain u8, to prevent accidental setting of ECN bits in ->flowi4_tos. Callers of ip_route_input() to consider are: * input_action_end_dx4_finish() and input_action_end_dt4() in net/ipv6/seg6_local.c. These functions set the tos parameter to 0, which is already a valid dscp_t value, so they don't need to be adjusted for the new prototype. * icmp_route_lookup(), which already has a dscp_t variable to pass as parameter. We just need to remove the inet_dscp_to_dsfield() conversion. * br_nf_pre_routing_finish(), ip_options_rcv_srr() and ip4ip6_err(), which get the DSCP directly from IPv4 headers. Define a helper to read the .tos field of struct iphdr as dscp_t, so that these function don't have to do the conversion manually. While there, declare *iph as const in br_nf_pre_routing_finish(), declare its local variables in reverse-christmas-tree order and move the "err = ip_route_input()" assignment out of the conditional to avoid checkpatch warning.

2024-10-04lib: packing: duplicate pack() and unpack() implementationsVladimir Oltean1-2/+2
packing() is now used in some hot paths, and it would be good to get rid of some ifs and buts that depend on "op", to speed things up a little bit. With the main implementations now taking size_t endbit, we no longer have to check for negative values. Update the local integer variables to also be size_t to match.

2024-10-04lib: packing: add pack() and unpack() wrappers over packing()Vladimir Oltean1-0/+6
Geert Uytterhoeven described packing() as "really bad API" because of not being able to enforce const correctness. The same function is used both when "pbuf" is input and "uval" is output, as in the other way around. Create 2 wrapper functions where const correctness can be ensured. Do ugly type casts inside, to be able to reuse packing() as currently implemented - which will _not_ modify the input argument. Also, take the opportunity to change the type of startbit and endbit to size_t - an unsigned type - in these new function prototypes. When int, an extra check for negative values is necessary. Hopefully, when packing() goes away completely, that check can be dropped. My concern is that code which does rely on the conditional directionality of packing() is harder to refactor without blowing up in size. So it may take a while to completely eliminate packing(). But let's make alternatives available for those who do not need that.

git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs Pull generic unaligned.h cleanups from Al Viro: "Get rid of architecture-specific <asm/unaligned.h> includes, replacing them with a single generic <linux/unaligned.h> header file. It's the second largest (after asm/io.h) class of asm/* includes, and all but two architectures actually end up using exact same file. Massage the remaining two (arc and parisc) to do the same and just move the thing to from asm-generic/unaligned.h to linux/unaligned.h" [ This is one of those things that we're better off doing outside the merge window, and would only cause extra conflict noise if it was in linux-next for the next release due to all the trivial #include line updates. Rip off the band-aid. - Linus ] * tag 'pull-work.unaligned' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: move asm/unaligned.h to linux/unaligned.h arc: get rid of private asm/unaligned.h parisc: get rid of private asm/unaligned.h

asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h
