2025-03-03Merge branch 'add-sock_kmemdup-helper'Jakub Kicinski
Geliang Tang says: ==================== add sock_kmemdup helper While developing MPTCP BPF path manager [1], I found it's useful to add a new sock_kmemdup() helper. My use case is this: In mptcp_userspace_pm_append_new_local_addr() function (see patch 3 in this patchset), it uses sock_kmalloc() to allocate an address entry "e", then immediately duplicate the input "entry" to it: ''' e = sock_kmalloc(sk, sizeof(*e), GFP_ATOMIC); if (!e) { ret = -ENOMEM; goto append_err; } *e = *entry; ''' When I implemented MPTCP BPF path manager, I needed to implement a code similar to this in BPF. The kfunc sock_kmalloc() can be easily invoked in BPF to allocate an entry "e", but the code "*e = *entry;" that assigns "entry" to "e" is not easy to implemented. I had to implement such a "copy entry" helper in BPF: ''' static void mptcp_pm_copy_addr(struct mptcp_addr_info *dst, struct mptcp_addr_info *src) { dst->id = src->id; dst->family = src->family; dst->port = src->port; if (src->family == AF_INET) { dst->addr.s_addr = src->addr.s_addr; } else if (src->family == AF_INET6) { dst->addr6.s6_addr32[0] = src->addr6.s6_addr32[0]; dst->addr6.s6_addr32[1] = src->addr6.s6_addr32[1]; dst->addr6.s6_addr32[2] = src->addr6.s6_addr32[2]; dst->addr6.s6_addr32[3] = src->addr6.s6_addr32[3]; } } static void mptcp_pm_copy_entry(struct mptcp_pm_addr_entry *dst, struct mptcp_pm_addr_entry *src) { mptcp_pm_copy_addr(&dst->addr, &src->addr); dst->flags = src->flags; dst->ifindex = src->ifindex; } ''' And add "write permission" for BPF to each field of mptcp_pm_addr_entry: ''' @@ static int bpf_mptcp_pm_btf_struct_access(struct bpf_verifier_log *log, case offsetof(struct mptcp_pm_addr_entry, addr.port): end = offsetofend(struct mptcp_pm_addr_entry, addr.port); break; #if IS_ENABLED(CONFIG_MPTCP_IPV6) case offsetof(struct mptcp_pm_addr_entry, addr.addr6.s6_addr32[0]): end = offsetofend(struct mptcp_pm_addr_entry, addr.addr6.s6_addr32[0]); break; case offsetof(struct mptcp_pm_addr_entry, addr.addr6.s6_addr32[1]): end = offsetofend(struct mptcp_pm_addr_entry, addr.addr6.s6_addr32[1]); break; case offsetof(struct mptcp_pm_addr_entry, addr.addr6.s6_addr32[2]): end = offsetofend(struct mptcp_pm_addr_entry, addr.addr6.s6_addr32[2]); break; case offsetof(struct mptcp_pm_addr_entry, addr.addr6.s6_addr32[3]): end = offsetofend(struct mptcp_pm_addr_entry, addr.addr6.s6_addr32[3]); break; #else case offsetof(struct mptcp_pm_addr_entry, addr.addr.s_addr): end = offsetofend(struct mptcp_pm_addr_entry, addr.addr.s_addr); break; #endif ''' But if there's a sock_kmemdup() helper, it will become much simpler, only need to call kfunc sock_kmemdup() instead in BPF. So this patchset adds this new helper and uses it in several places.

2025-03-03mptcp: use sock_kmemdup for address entryGeliang Tang
Instead of using sock_kmalloc() to allocate an address entry "e" and then immediately duplicate the input "entry" to it, the newly added sock_kmemdup() helper can be used in mptcp_userspace_pm_append_new_local_addr() to simplify the code. More importantly, the code "*e = *entry;" that assigns "entry" to "e" is not easy to implemented in BPF if we use the same code to implement an append_new_local_addr() helper of a BFP path manager.

2025-02-28inet: ping: avoid skb_clone() dance in ping_rcv()Eric Dumazet
ping_rcv() callers currently call skb_free() or consume_skb(), forcing ping_rcv() to clone the skb. After this patch ping_rcv() is now 'consuming' the original skb, either moving to a socket receive queue, or dropping it.

2025-02-28Merge branch 'net-stmmac-cleanup-transmit-clock-setting'Jakub Kicinski
Russell King says: ==================== net: stmmac: cleanup transmit clock setting A lot of stmmac platform code which sets the transmit clock is very similar - they decode the speed to the clock rate (125, 25 or 2.5 MHz) and then set a clock to that rate. The DWMAC core appears to have a clock input for the transmit section called clk_tx_i which requires this rate. This series moves the code which sets this clock into the core stmmac code. Patch 1 adds a hook that platforms can use to configure the clock rate. Patch 2 adds a generic implementation. The remainder of the patches convert the glue code for various platforms to use this new infrastructure. ==================== Link: https://patch.msgid.link/Z8AtX-wyPal1auVO@shell.armlinux.org.uk Signed-off-by: Jakub Kicinski <kuba@kernel.org>

Use the generic stmmac_set_clk_tx_rate() to configure the MAC transmit clock. Note that given the current unpatched driver structure, plat_dat->fix_mac_speed will always be populated with kmb_eth_fix_mac_speed(), even when no clock is present. We preserve this behaviour in this patch by always initialising plat_dat->clk_tx_i and plat_dat->set_clk_tx_rate.

Provide a generic implementation for the set_clk_tx_rate method introduced by the previous patch, which is capable of configuring the MAC transmit clock for 10M, 100M and 1000M speeds for at least MII, GMII, RGMII and RMII interface modes.
