2022-06-03perf record: Support sample-read topdown metric group for hybrid platformsZhengjun Xing
With the hardware TopDown metrics feature, the sample-read feature should be supported for a TopDown group, e.g., sample a non-topdown event and read a Topdown metric group. But the current perf record code errors are out. For a TopDown metric group,the slots event must be the leader of the group, but the leader slots event doesn't support sampling. To support sample-read the TopDown metric group, uses the 2nd event of the group as the "leader" for the purposes of sampling. Only the platform with the TopDown metric feature supports sample-read the topdown group. In commit acb65150a47c ("perf record: Support sample-read topdown metric group"), it adds arch_topdown_sample_read() to indicate whether the TopDown group supports sample-read, it should only work on the non-hybrid systems, this patch extends the support for hybrid platforms. Before: # ./perf record -e "{cpu_core/slots/,cpu_core/cycles/,cpu_core/topdown-retiring/}:S" -a sleep 1 Error: The sys_perf_event_open() syscall returned with 22 (Invalid argument) for event (cpu_core/topdown-retiring/). /bin/dmesg | grep -i perf may provide additional information.

2022-06-03perf unwind: Fix segbase for ld.lld linked objectsFangrui Song
segbase is the address of .eh_frame_hdr and table_data is segbase plus the header size. find_proc_info computes segbase as `map->start + segbase - map->pgoff` which is wrong when * .eh_frame_hdr and .text are in different PT_LOAD program headers * and their p_vaddr difference does not equal their p_offset difference Since 10.0, ld.lld's default --rosegment -z noseparate-code layout has such R and RX PT_LOAD program headers. ld.lld (default) => perf report fails to unwind `perf record --call-graph dwarf` recorded data ld.lld --no-rosegment => ok (trivial, no R PT_LOAD) ld.lld -z separate-code => ok but by luck: there are two PT_LOAD but their p_vaddr difference equals p_offset difference ld.bfd -z noseparate-code => ok (trivial, no R PT_LOAD) ld.bfd -z separate-code (default for Linux/x86) => ok but by luck: there are two PT_LOAD but their p_vaddr difference equals p_offset difference To fix the issue, compute segbase as dso's base address plus PT_GNU_EH_FRAME's p_vaddr. The base address is computed by iterating over all dso-associated maps and then subtract the first PT_LOAD p_vaddr (the minimum guaranteed by generic ABI) from the minimum address. In libunwind, find_proc_info transitively called by unw_step is cached, so the iteration overhead is acceptable.

2022-06-03perf evlist: Extend arch_evsel__must_be_in_group to support hybrid systemsZhengjun Xing
For the hybrid system, the "slots" event changes to "cpu_core/slots/", need extend API arch_evsel__must_be_in_group() to support hybrid systems. In the origin code, for hybrid system event "cpu_core/slots/", the output of the API arch_evsel__must_be_in_group() is "false" (in fact,it should be "true"). Currently only one API evsel__remove_from_group() calls it. In evsel__remove_from_group(), it adds the second condition to check, so the output of evsel__remove_from_group() still is correct. That's the reason why there isn't an instant error. I'd like to fix the issue found in API arch_evsel__must_be_in_group() in case someone else using the function in the other place.

2022-06-03driver core: Set default deferred_probe_timeout back to 0.Saravana Kannan
Since we had to effectively reverted commit 35a672363ab3 ("driver core: Ensure wait_for_device_probe() waits until the deferred_probe_timeout fires") in an earlier patch, a non-zero deferred_probe_timeout will break NFS rootfs mounting [1] again. So, set the default back to zero until we can fix that.

2022-06-03driver core: Fix wait_for_device_probe() & deferred_probe_timeout interactionSaravana Kannan
Mounting NFS rootfs was timing out when deferred_probe_timeout was non-zero [1]. This was because ip_auto_config() initcall times out waiting for the network interfaces to show up when deferred_probe_timeout was non-zero. While ip_auto_config() calls wait_for_device_probe() to make sure any currently running deferred probe work or asynchronous probe finishes, that wasn't sufficient to account for devices being deferred until deferred_probe_timeout. Commit 35a672363ab3 ("driver core: Ensure wait_for_device_probe() waits until the deferred_probe_timeout fires") tried to fix that by making sure wait_for_device_probe() waits for deferred_probe_timeout to expire before returning. However, if wait_for_device_probe() is called from the kernel_init() context: - Before deferred_probe_initcall() [2], it causes the boot process to hang due to a deadlock. - After deferred_probe_initcall() [3], it blocks kernel_init() from continuing till deferred_probe_timeout expires and beats the point of deferred_probe_timeout that's trying to wait for userspace to load modules. Neither of this is good. So revert the changes to wait_for_device_probe().

Lots of tiny driver core changes and cleanups happened this cycle, but the two major things are: - firmware_loader reorganization and additions including the ability to have XZ compressed firmware images and the ability for userspace to initiate the firmware load when it needs to, instead of being always initiated by the kernel. FPGA devices specifically want this ability to have their firmware changed over the lifetime of the system boot, and this allows them to work without having to come up with yet-another-custom-uapi interface for loading firmware for them. - physical location support added to sysfs so that devices that know this information, can tell userspace where they are located in a common way. Some ACPI devices already support this today, and more bus types should support this in the future. Smaller changes include: - driver_override api cleanups and fixes - error path cleanups and fixes - get_abi script fixes - deferred probe timeout changes. It's that last change that I'm the most worried about. It has been reported to cause boot problems for a number of systems, and I have a tested patch series that resolves this issue.

Lots of forward progress happened this development cycle, one driver (wfx wireless driver) got merged into the real portion of the kernel, and another one (unisys) was removed as no one is around anymore to take care of it and no one has the hardware.

2022-06-02block: Fix potential deadlock in blk_ia_range_sysfs_show()Damien Le Moal
When being read, a sysfs attribute is already protected against removal with the kobject node active reference counter. As a result, in blk_ia_range_sysfs_show(), there is no need to take the queue sysfs lock when reading the value of a range attribute. Using the queue sysfs lock in this function creates a potential deadlock situation with the disk removal, something that a lockdep signals with a splat when the device is removed: [ 760.703551] Possible unsafe locking scenario: [ 760.703551] [ 760.703554] CPU0 CPU1 [ 760.703556] ---- ---- [ 760.703558] lock(&q->sysfs_lock); [ 760.703565] lock(kn->active#385); [ 760.703573] lock(&q->sysfs_lock); [ 760.703579] lock(kn->active#385); [ 760.703587] [ 760.703587] *** DEADLOCK *** Solve this by removing the mutex_lock()/mutex_unlock() calls from blk_ia_range_sysfs_show().

2022-06-02module: Fix prefix for module.sig_enforce module paramSaravana Kannan
Commit cfc1d277891e ("module: Move all into module/") changed the prefix of the module param by moving/renaming files. A later commit also moves the module_param() into a different file, thereby changing the prefix yet again. This would break kernel cmdline compatibility and also userspace compatibility at /sys/module/module/parameters/sig_enforce. So, set the prefix back to "module.".

Eric Dumazet says: ==================== net: af_packet: be careful when expanding mac header size A recent regression in af_packet needed a preliminary debug patch, which will presumably be useful for next bugs hunting. The af_packet fix is to make sure MAC headers are contained in skb linear part, as GSO stack requests. v2: CONFIG_DEBUG_NET depends on CONFIG_NET to avoid compile errors found by kernel bots. ==================== Link: https://lore.kernel.org/r/20220602161859.2546399-1-eric.dumazet@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2022-06-02net/af_packet: make sure to pull mac headerEric Dumazet
GSO assumes skb->head contains link layer headers. tun device in some case can provide base 14 bytes, regardless of VLAN being used or not. After blamed commit, we can end up setting a network header offset of 18+, we better pull the missing bytes to avoid a posible crash in GSO. syzbot report was: kernel BUG at include/linux/skbuff.h:2699! invalid opcode: 0000 [#1] PREEMPT SMP KASAN CPU: 1 PID: 3601 Comm: syz-executor210 Not tainted 5.18.0-syzkaller-11338-g2c5ca23f7414 #0 Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 01/01/2011 RIP: 0010:__skb_pull include/linux/skbuff.h:2699 [inline] RIP: 0010:skb_mac_gso_segment+0x48f/0x530 net/core/gro.c:136 Code: 00 48 c7 c7 00 96 d4 8a c6 05 cb d3 45 06 01 e8 26 bb d0 01 e9 2f fd ff ff 49 c7 c4 ea ff ff ff e9 f1 fe ff ff e8 91 84 19 fa <0f> 0b 48 89 df e8 97 44 66 fa e9 7f fd ff ff e8 ad 44 66 fa e9 48 RSP: 0018:ffffc90002e2f4b8 EFLAGS: 00010293 RAX: 0000000000000000 RBX: 0000000000000012 RCX: 0000000000000000 RDX: ffff88805bb58000 RSI: ffffffff8760ed0f RDI: 0000000000000004 RBP: 0000000000005dbc R08: 0000000000000004 R09: 0000000000000fe0 R10: 0000000000000fe4 R11: 0000000000000000 R12: 0000000000000fe0 R13: ffff88807194d780 R14: 1ffff920005c5e9b R15: 0000000000000012 FS: 000055555730f300(0000) GS:ffff8880b9d00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00000000200015c0 CR3: 0000000071ff8000 CR4: 0000000000350ee0 Call Trace: <TASK> __skb_gso_segment+0x327/0x6e0 net/core/dev.c:3411 skb_gso_segment include/linux/netdevice.h:4749 [inline] validate_xmit_skb+0x6bc/0xf10 net/core/dev.c:3669 validate_xmit_skb_list+0xbc/0x120 net/core/dev.c:3719 sch_direct_xmit+0x3d1/0xbe0 net/sched/sch_generic.c:327 __dev_xmit_skb net/core/dev.c:3815 [inline] __dev_queue_xmit+0x14a1/0x3a00 net/core/dev.c:4219 packet_snd net/packet/af_packet.c:3071 [inline] packet_sendmsg+0x21cb/0x5550 net/packet/af_packet.c:3102 sock_sendmsg_nosec net/socket.c:714 [inline] sock_sendmsg+0xcf/0x120 net/socket.c:734 ____sys_sendmsg+0x6eb/0x810 net/socket.c:2492 ___sys_sendmsg+0xf3/0x170 net/socket.c:2546 __sys_sendmsg net/socket.c:2575 [inline] __do_sys_sendmsg net/socket.c:2584 [inline] __se_sys_sendmsg net/socket.c:2582 [inline] __x64_sys_sendmsg+0x132/0x220 net/socket.c:2582 do_syscall_x64 arch/x86/entry/common.c:50 [inline] do_syscall_64+0x35/0xb0 arch/x86/entry/common.c:80 entry_SYSCALL_64_after_hwframe+0x46/0xb0 RIP: 0033:0x7f4b95da06c9 Code: 28 c3 e8 4a 15 00 00 66 2e 0f 1f 84 00 00 00 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 c0 ff ff ff f7 d8 64 89 01 48 RSP: 002b:00007ffd7defc4c8 EFLAGS: 00000246 ORIG_RAX: 000000000000002e RAX: ffffffffffffffda RBX: 00007ffd7defc4f0 RCX: 00007f4b95da06c9 RDX: 0000000000000000 RSI: 0000000020000140 RDI: 0000000000000003 RBP: 0000000000000003 R08: bb1414ac00000050 R09: bb1414ac00000050 R10: 0000000000000004 R11: 0000000000000246 R12: 0000000000000000 R13: 00007ffd7defc4e0 R14: 00007ffd7defc4d8 R15: 00007ffd7defc4d4 </TASK> Fixes: dfed913e8b55 ("net/af_packet: add VLAN support for AF_PACKET SOCK_RAW GSO") Signed-off-by: Eric Dumazet <edumazet@google.com> Reported-by: syzbot <syzkaller@googlegroups.com> Acked-by: Hangbin Liu <liuhangbin@gmail.com> Acked-by: Willem de Bruijn <willemb@google.com> Cc: Michael S.

I have a board where these two lines are always printed during boot: imx-dwmac 30bf0000.ethernet: Cannot register the MDIO bus imx-dwmac 30bf0000.ethernet: stmmac_dvr_probe: MDIO bus (id: 1) registration failed It's perfectly fine, and the device is successfully (and silently, as far as the console goes) probed later. Use dev_err_probe() instead, which will demote these messages to debug level (thus removing the alarming messages from the console) when the error is -EPROBE_DEFER, and also has the advantage of including the error code if/when it happens to be something other than -EPROBE_DEFER.

2022-06-02binder: fix sender_euid type in uapi headerCarlos Llamas
The {pid,uid}_t fields of struct binder_transaction were recently replaced to use kernel types in commit 169adc2b6b3c ("android/binder.h: add linux/android/binder(fs).h to UAPI compile-test coverage"). However, using __kernel_uid_t here breaks backwards compatibility in architectures using 16-bits for this type, since glibc and some others still expect a 32-bit uid_t. Instead, let's use __kernel_uid32_t which avoids this compatibility problem.
