split __bpf_prog_run() interpreter into stack allocation and execution parts.

Back in commit f60e599 ("ipv6: protect skb->sk accesses from recursive dereference inside the stack") Hannes added code so that IPv6 stack would not trust skb->sk for typical cases where packet goes through 'standard' xmit path (__dev_queue_xmit()) Alas af_packet had a dev_direct_xmit() path that was not dealing yet with xmit_recursion level. Also change sk_mc_loop() to dump a stack once only.

Back in commit f60e599 ("ipv6: protect skb->sk accesses from recursive dereference inside the stack") Hannes added code so that IPv6 stack would not trust skb->sk for typical cases where packet goes through 'standard' xmit path (__dev_queue_xmit()) Alas af_packet had a dev_direct_xmit() path that was not dealing yet with xmit_recursion level. Also change sk_mc_loop() to dump a stack once only. Without this patch, syzbot was able to trigger : [1] [ 153.567378] WARNING: CPU: 7 PID: 11273 at net/core/sock.c:721 sk_mc_loop+0x51/0x70 [ 153.567378] Modules linked in: nfnetlink ip6table_raw ip6table_filter iptable_raw iptable_nat nf_nat nf_conntrack nf_defrag_ipv4 nf_defrag_ipv6 iptable_filter macsec macvtap tap macvlan 8021q hsr wireguard libblake2s blake2s_x86_64 libblake2s_generic udp_tunnel ip6_udp_tunnel libchacha20poly1305 poly1305_x86_64 chacha_x86_64 libchacha curve25519_x86_64 libcurve25519_generic netdevsim batman_adv dummy team bridge stp llc w1_therm wire i2c_mux_pca954x i2c_mux cdc_acm ehci_pci ehci_hcd mlx4_en mlx4_ib ib_uverbs ib_core mlx4_core [ 153.567386] CPU: 7 PID: 11273 Comm: b159172088 Not tainted 5.8.0-smp-DEV torvalds#273 [ 153.567387] RIP: 0010:sk_mc_loop+0x51/0x70 [ 153.567388] Code: 66 83 f8 0a 75 24 0f b6 4f 12 b8 01 00 00 00 31 d2 d3 e0 a9 bf ef ff ff 74 07 48 8b 97 f0 02 00 00 0f b6 42 3a 83 e0 01 5d c3 <0f> 0b b8 01 00 00 00 5d c3 0f b6 87 18 03 00 00 5d c0 e8 04 83 e0 [ 153.567388] RSP: 0018:ffff95c69bb93990 EFLAGS: 00010212 [ 153.567388] RAX: 0000000000000011 RBX: ffff95c6e0ee3e00 RCX: 0000000000000007 [ 153.567389] RDX: ffff95c69ae50000 RSI: ffff95c6c30c3000 RDI: ffff95c6c30c3000 [ 153.567389] RBP: ffff95c69bb93990 R08: ffff95c69a77f000 R09: 0000000000000008 [ 153.567389] R10: 0000000000000040 R11: 00003e0e00026128 R12: ffff95c6c30c3000 [ 153.567390] R13: ffff95c6cc4fd500 R14: ffff95c6f84500c0 R15: ffff95c69aa13c00 [ 153.567390] FS: 00007fdc3a283700(0000) GS:ffff95c6ff9c0000(0000) knlGS:0000000000000000 [ 153.567390] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 153.567391] CR2: 00007ffee758e890 CR3: 0000001f9ba20003 CR4: 00000000001606e0 [ 153.567391] Call Trace: [ 153.567391] ip6_finish_output2+0x34e/0x550 [ 153.567391] __ip6_finish_output+0xe7/0x110 [ 153.567391] ip6_finish_output+0x2d/0xb0 [ 153.567392] ip6_output+0x77/0x120 [ 153.567392] ? __ip6_finish_output+0x110/0x110 [ 153.567392] ip6_local_out+0x3d/0x50 [ 153.567392] ipvlan_queue_xmit+0x56c/0x5e0 [ 153.567393] ? ksize+0x19/0x30 [ 153.567393] ipvlan_start_xmit+0x18/0x50 [ 153.567393] dev_direct_xmit+0xf3/0x1c0 [ 153.567393] packet_direct_xmit+0x69/0xa0 [ 153.567394] packet_sendmsg+0xbf0/0x19b0 [ 153.567394] ? plist_del+0x62/0xb0 [ 153.567394] sock_sendmsg+0x65/0x70 [ 153.567394] sock_write_iter+0x93/0xf0 [ 153.567394] new_sync_write+0x18e/0x1a0 [ 153.567395] __vfs_write+0x29/0x40 [ 153.567395] vfs_write+0xb9/0x1b0 [ 153.567395] ksys_write+0xb1/0xe0 [ 153.567395] __x64_sys_write+0x1a/0x20 [ 153.567395] do_syscall_64+0x43/0x70 [ 153.567396] entry_SYSCALL_64_after_hwframe+0x44/0xa9 [ 153.567396] RIP: 0033:0x453549 [ 153.567396] Code: Bad RIP value.

The function meson_clk_pll_enable() can be invoked under the enable_lock spinlock from the clk core logic, which risks a kernel panic during the usleep_range() call: BUG: scheduling while atomic: kworker/u4:2/36/0x00000002 Modules linked in: g_ffs usb_f_fs libcomposite CPU: 1 PID: 36 Comm: kworker/u4:2 Not tainted 6.4.0-rc5 torvalds#273 Workqueue: events_unbound async_run_entry_fn Call trace: dump_backtrace+0x9c/0x128 show_stack+0x20/0x38 dump_stack_lvl+0x48/0x60 dump_stack+0x18/0x28 __schedule_bug+0x58/0x78 __schedule+0x828/0xa88 schedule+0x64/0xd8 schedule_hrtimeout_range_clock+0xd0/0x208 schedule_hrtimeout_range+0x1c/0x30 usleep_range_state+0x6c/0xa8 meson_clk_pll_enable+0x1f4/0x310 clk_core_enable+0x78/0x200 clk_core_enable+0x58/0x200 clk_core_enable+0x58/0x200 clk_core_enable+0x58/0x200 clk_enable+0x34/0x60 So it is required to use the udelay() function instead of usleep_range() for the atomic context safety.
