Make the entire combination of plls to be one single clock. The parents used for bypasses are specified each as an index in the parents list. The determine_rate does a lookup throughout all the possible combinations for all the divs and returns the best possible 'setup' which in turn is used by set_rate later to set up all the divs and bypasses.

On NXP's i.MX SoCs with system controller inside, CPU frequency scaling can ONLY be done by system controller firmware, and it can ONLY be requested from secure mode, so Linux kernel has to call ARM SMC to trap to ARM-Trusted-Firmware to request system controller firmware to do CPU frequency scaling. This patch adds i.MX system controller CPU frequency scaling support, it reuses cpufreq-dt driver and implement the CPU frequency scaling inside SCU clock driver. Signed-off-by:

This fixes a regression introduced by commit 0d2e778e "net: phy: replace PHY_HAS_INTERRUPT with a check for config_intr and ack_interrupt". This assumes that a PHY cannot trigger interrupt unless it has .config_intr() or .ack_interrupt() implemented. A later patch makes the code assume both need to be implemented for interrupts to be present. But this PHY (which is inside a DSA) will happily fire interrupts without either callback. Implement dummy callbacks for .config_intr() and .ack_interrupt() in the phy header to fix this. Tested on the RTL8366RB on D-Link DIR-685.

syzbot was able to trigger another soft lockup [1] I first thought it was the O(N^2) issue I mentioned in my prior fix (f657d22ee1f "net/x25: do not hold the cpu too long in x25_new_lci()"), but I eventually found that x25_bind() was not checking SOCK_ZAPPED state under socket lock protection. This means that multiple threads can end up calling x25_insert_socket() for the same socket, and corrupt x25_list [1] watchdog: BUG: soft lockup - CPU#0 stuck for 123s!

This reverts commit 5a2de63f ("bridge: do not add port to router list when receives query with source 0.0.0.0") and commit 0fe5119e ("net: bridge: remove ipv6 zero address check in mcast queries") The reason is RFC 4541 is not a standard but suggestive. Currently we will elect 0.0.0.0 as Querier if there is no ip address configured on bridge. If we do not add the port which recives query with source 0.0.0.0 to router list, the IGMP reports will not be about to forward to Querier, IGMP data will also not be able to forward to dest. As Nikolay suggested, revert this change first and add a boolopt api to disable none-zero election in future if needed. Reported-by:

Just like commit e2ba732a ("selftests: fib_tests: sleep after changing carrier"), wait one second to allow linkwatch to propagate the carrier change to the stack. There are two sets of carrier tests. The first slept after the carrier was set to off, and when the second set ran, it was likely that the linkwatch would be able to run again without much delay, reducing the likelihood of a race. However, if you run 'fib_tests.sh -t carrier' on a loop, you will quickly notice the failures. Sleeping on the second set of tests make the failures go away.

We recently created a bpf@vger.kernel.org list (https://lore.kernel.org/bpf/) for BPF related discussions, originally in context of BPF track at LSF/MM for topic discussions. It's *optional* but *desirable* to keep it in Cc for BPF related kernel/loader/llvm/tooling threads, meaning also infrastructure like llvm that sits on top of kernel but is crucial to BPF. In any case, netdev with it's bpf delegate is *as-is* today primary list for patches, so nothing changes in the workflow. Main purpose is to have some more awareness for the bpf@vger.kernel.org list that folks can Cc for BPF specific topics. Acked-by:

KASAN has found use-after-free in fixed_mdio_bus_init, commit 0c692d07 ("drivers/net/phy/mdio_bus.c: call put_device on device_register() failure") call put_device() while device_register() fails,give up the last reference to the device and allow mdiobus_release to be executed ,kfreeing the bus. However in most drives, mdiobus_free be called to free the bus while mdiobus_register fails. use-after-free occurs when access bus again, this patch revert it to let mdiobus_free free the bus. KASAN report details as below: BUG: KASAN: use-after-free in mdiobus_free+0x85/0x90 drivers/net/phy/mdio_bus.c:482 Read of size 4 at addr ffff8881dc824d78 by task syz-executor.0/3524 CPU: 1 PID: 3524 Comm: syz-executor.0 Not tainted 5.0.0-rc7+ #45 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.10.2-1ubuntu1 04/01/2014 Call Trace: __dump_stack lib/dump_stack.c:77 [inline] dump_stack+0xfa/0x1ce lib/dump_stack.c:113 print_address_description+0x65/0x270 mm/kasan/report.c:187 kasan_report+0x149/0x18d mm/kasan/report.c:317 mdiobus_free+0x85/0x90 drivers/net/phy/mdio_bus.c:482 fixed_mdio_bus_init+0x283/0x1000 [fixed_phy] ? 0xffffffffc0e40000 ? 0xffffffffc0e40000 ? 0xffffffffc0e40000 do_one_initcall+0xfa/0x5ca init/main.c:887 do_init_module+0x204/0x5f6 kernel/module.c:3460 load_module+0x66b2/0x8570 kernel/module.c:3808 __do_sys_finit_module+0x238/0x2a0 kernel/module.c:3902 do_syscall_64+0x147/0x600 arch/x86/entry/common.c:290 entry_SYSCALL_64_after_hwframe+0x49/0xbe RIP: 0033:0x462e99 Code: f7 d8 64 89 02 b8 ff ff ff ff c3 66 0f 1f 44 00 00 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d 89 c2 4d 89 c8 4c 8b 4c 24 08 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 c7 c1 bc ff ff ff f7 d8 64 89 01 48 RSP: 002b:00007f6215c19c58 EFLAGS: 00000246 ORIG_RAX: 0000000000000139 RAX: ffffffffffffffda RBX: 000000000073bf00 RCX: 0000000000462e99 RDX: 0000000000000000 RSI: 0000000020000080 RDI: 0000000000000003 RBP: 00007f6215c19c70 R08: 0000000000000000 R09: 0000000000000000 R10: 0000000000000000 R11: 0000000000000246 R12: 00007f6215c1a6bc R13: 00000000004bcefb R14: 00000000006f7030 R15: 0000000000000004 Allocated by task 3524: set_track mm/kasan/common.c:85 [inline] __kasan_kmalloc.constprop.3+0xa0/0xd0 mm/kasan/common.c:496 kmalloc include/linux/slab.h:545 [inline] kzalloc include/linux/slab.h:740 [inline] mdiobus_alloc_size+0x54/0x1b0 drivers/net/phy/mdio_bus.c:143 fixed_mdio_bus_init+0x163/0x1000 [fixed_phy] do_one_initcall+0xfa/0x5ca init/main.c:887 do_init_module+0x204/0x5f6 kernel/module.c:3460 load_module+0x66b2/0x8570 kernel/module.c:3808 __do_sys_finit_module+0x238/0x2a0 kernel/module.c:3902 do_syscall_64+0x147/0x600 arch/x86/entry/common.c:290 entry_SYSCALL_64_after_hwframe+0x49/0xbe Freed by task 3524: set_track mm/kasan/common.c:85 [inline] __kasan_slab_free+0x130/0x180 mm/kasan/common.c:458 slab_free_hook mm/slub.c:1409 [inline] slab_free_freelist_hook mm/slub.c:1436 [inline] slab_free mm/slub.c:2986 [inline] kfree+0xe1/0x270 mm/slub.c:3938 device_release+0x78/0x200 drivers/base/core.c:919 kobject_cleanup lib/kobject.c:662 [inline] kobject_release lib/kobject.c:691 [inline] kref_put include/linux/kref.h:67 [inline] kobject_put+0x146/0x240 lib/kobject.c:708 put_device+0x1c/0x30 drivers/base/core.c:2060 __mdiobus_register+0x483/0x560 drivers/net/phy/mdio_bus.c:382 fixed_mdio_bus_init+0x26b/0x1000 [fixed_phy] do_one_initcall+0xfa/0x5ca init/main.c:887 do_init_module+0x204/0x5f6 kernel/module.c:3460 load_module+0x66b2/0x8570 kernel/module.c:3808 __do_sys_finit_module+0x238/0x2a0 kernel/module.c:3902 do_syscall_64+0x147/0x600 arch/x86/entry/common.c:290 entry_SYSCALL_64_after_hwframe+0x49/0xbe The buggy address belongs to the object at ffff8881dc824c80 which belongs to the cache kmalloc-2k of size 2048 The buggy address is located 248 bytes inside of 2048-byte region [ffff8881dc824c80, ffff8881dc825480) The buggy address belongs to the page: page:ffffea0007720800 count:1 mapcount:0 mapping:ffff8881f6c02800 index:0x0 compound_mapcount: 0 flags: 0x2fffc0000010200(slab|head) raw: 02fffc0000010200 0000000000000000 0000000500000001 ffff8881f6c02800 raw: 0000000000000000 00000000800f000f 00000001ffffffff 0000000000000000 page dumped because: kasan: bad access detected Memory state around the buggy address: ffff8881dc824c00: fc fc fc fc fc fc fc fc fc fc fc fc fc fc fc fc ffff8881dc824c80: fb fb fb fb fb fb fb fb fb fb fb fb fb fb fb fb >ffff8881dc824d00: fb fb fb fb fb fb fb fb fb fb fb fb fb fb fb fb ^ ffff8881dc824d80: fb fb fb fb fb fb fb fb fb fb fb fb fb fb fb fb ffff8881dc824e00: fb fb fb fb fb fb fb fb fb fb fb fb fb fb fb fb Fixes: 0c692d07 ("drivers/net/phy/mdio_bus.c: call put_device on device_register() failure") Signed-off-by:

Set rtm_table to RT_TABLE_COMPAT for ipv6 for tables > 255 to keep legacy software happy. This is similar to what was done for ipv4 in commit 709772e6 ("net: Fix routing tables with id > 255 for legacy software"). Signed-off-by:

The code waits up to 20 usec for the firmware response to complete once we've seen the valid response header in the buffer. It turns out that in some scenarios, this wait time is not long enough. Extend it to 150 usec and use usleep_range() instead of udelay(). Fixes: 9751e8e7 ("bnxt_en: reduce timeout on initial HWRM calls") Signed-off-by:

The logic that polls for the firmware message response uses a shorter sleep interval for the first few passes. But there was a typo so it was using the wrong counter (larger counter) for these short sleep passes. The result is a slightly shorter timeout period for these firmware messages than intended. Fix it by using the proper counter. Fixes: 9751e8e7 ("bnxt_en: reduce timeout on initial HWRM calls") Signed-off-by:
