This v6.8 change didn't make it into the release, send it as a fix for v6.9.
2024-04-03thermal: gov_power_allocator: Allow binding without trip pointsNikita Travkin1-8/+4
IPA probe function was recently refactored to perform extra error checks and make sure the thermal zone has trip points necessary for the IPA operation. With this change, if a thermal zone is probed such that it has no trip points that IPA can use, IPA will fail and the TZ won't be created. This is the case if a platform defines a TZ without cooling devices and only with "hot"/"critical" trip points, often found on some Qualcomm devices [1]. Documentation across IPA code (notably get_governor_trips() kerneldoc) suggests that IPA is supposed to handle such TZ even if it won't actually do anything. This commit partially reverts the previous change to allow IPA to bind to such "empty" thermal zones.

2024-04-03thermal: gov_power_allocator: Allow binding without cooling devicesNikita Travkin1-1/+1
IPA was recently refactored to split out memory allocation into a separate funciton. That funciton was made to return -EINVAL if there is zero power_actors and thus no memory to allocate. This causes IPA to fail probing when the thermal zone has no attached cooling devices. Since cooling devices can attach after the thermal zone is created and the governer is attached to it, failing probe due to the lack of cooling devices is incorrect. Change the allocate_actors_buffer() to return success when there is no cooling devices present.

2024-04-03arm64/ptrace: Use saved floating point state type to determine SVE layoutMark Brown1-4/+1
The SVE register sets have two different formats, one of which is a wrapped version of the standard FPSIMD register set and another with actual SVE register data. At present we check TIF_SVE to see if full SVE register state should be provided when reading the SVE regset but if we were in a syscall we may have saved only floating point registers even though that is set. Fix this and simplify the logic by checking and using the format which we recorded when deciding if we should use FPSIMD or SVE format.

2024-04-03s390/mm: fix NULL pointer dereferenceHeiko Carstens1-1/+1
The recently added check to figure out if a fault happened on gmap ASCE dereferences the gmap pointer in lowcore without checking that it is not NULL. For all non-KVM processes the pointer is NULL, so that some value from lowcore will be read. With the current layouts of struct gmap and struct lowcore the read value (aka ASCE) is zero, so that this doesn't lead to any observable bug; at least currently. Fix this by adding the missing NULL pointer check.

2024-04-03net: bcmgenet: Reset RBUF on first openPhil Elwell1-4/+12
If the RBUF logic is not reset when the kernel starts then there may be some data left over from any network boot loader. If the 64-byte packet headers are enabled then this can be fatal. Extend bcmgenet_dma_disable to do perform the reset, but not when called from bcmgenet_resume in order to preserve a wake packet. N.B. This different handling of resume is just based on a hunch - why else wouldn't one reset the RBUF as well as the TBUF? If this isn't the case then it's easy to change the patch to make the RBUF reset unconditional.

In function pci1xxxx_spi_probe, there is a potential null pointer that may be caused by a failed memory allocation by the function devm_kzalloc. Hence, a null pointer check needs to be added to prevent null pointer dereferencing later in the code. To fix this issue, spi_bus->spi_int[iter] should be checked. The memory allocated by devm_kzalloc will be automatically released, so just directly return -ENOMEM without worrying about memory leaks.

2024-04-03perf/x86/intel/ds: Don't clear ->pebs_data_cfg for the last PEBS eventKan Liang1-4/+4
The MSR_PEBS_DATA_CFG MSR register is used to configure which data groups should be generated into a PEBS record, and it's shared among all counters. If there are different configurations among counters, perf combines all the configurations. The first perf command as below requires a complete PEBS record (including memory info, GPRs, XMMs, and LBRs). The second perf command only requires a basic group. However, after the second perf command is running, the MSR_PEBS_DATA_CFG register is cleared. Only a basic group is generated in a PEBS record, which is wrong. The required information for the first perf command is missed. $ perf record --intr-regs=AX,SP,XMM0 -a -C 8 -b -W -d -c 100000003 -o /dev/null -e cpu/event=0xd0,umask=0x81/upp & $ sleep 5 $ perf record --per-thread -c 1 -e cycles:pp --no-timestamp --no-tid taskset -c 8 ./noploop 1000 The first PEBS event is a system-wide PEBS event. The second PEBS event is a per-thread event. When the thread is scheduled out, the intel_pmu_pebs_del() function is invoked to update the PEBS state. Since the system-wide event is still available, the cpuc->n_pebs is 1. The cpuc->pebs_data_cfg is cleared. The data configuration for the system-wide PEBS event is lost. The (cpuc->n_pebs == 1) check was introduced in commit: b6a32f023fcc ("perf/x86: Fix PEBS threshold initialization") At that time, it indeed didn't hurt whether the state was updated during the removal, because only the threshold is updated. The calculation of the threshold takes the last PEBS event into account. However, since commit: b752ea0c28e3 ("perf/x86/intel/ds: Flush PEBS DS when changing PEBS_DATA_CFG") we delay the threshold update, and clear the PEBS data config, which triggers the bug. The PEBS data config update scope should not be shrunk during removal.

Because the kernel is configured with CONFIG_NO_HZ_FULL the search for another CPU (in its effort to prefer those CPUs that aren't marked nohz_full) consults the mask representing the nohz_full CPUs, tick_nohz_full_mask. On a kernel with CONFIG_CPUMASK_OFFSTACK=y tick_nohz_full_mask is not allocated unless the kernel is booted with the "nohz_full=" parameter and because of that any access to tick_nohz_full_mask needs to be guarded with tick_nohz_full_enabled(). Replace the IS_ENABLED(CONFIG_NO_HZ_FULL) with tick_nohz_full_enabled(). The latter ensures tick_nohz_full_mask can be accessed safely and can be used whether kernel is built with CONFIG_NO_HZ_FULL enabled or not.

2024-04-03ipv6: Fix infinite recursion in fib6_dump_done().Kuniyuki Iwashima1-7/+7
syzkaller reported infinite recursive calls of fib6_dump_done() during netlink socket destruction. [1] From the log, syzkaller sent an AF_UNSPEC RTM_GETROUTE message, and then the response was generated. The following recvmmsg() resumed the dump for IPv6, but the first call of inet6_dump_fib() failed at kzalloc() due to the fault injection. [0] 12:01:34 executing program 3: r0 = socket$nl_route(0x10, 0x3, 0x0) sendmsg$nl_route(r0, ... snip ...) recvmmsg(r0, ... snip ...) (fail_nth: 8) Here, fib6_dump_done() was set to nlk_sk(sk)->cb.done, and the next call of inet6_dump_fib() set it to nlk_sk(sk)->cb.args[3]. syzkaller stopped receiving the response halfway through, and finally netlink_sock_destruct() called nlk_sk(sk)->cb.done(). fib6_dump_done() calls fib6_dump_end() and nlk_sk(sk)->cb.done() if it is still not NULL. fib6_dump_end() rewrites nlk_sk(sk)->cb.done() by nlk_sk(sk)->cb.args[3], but it has the same function, not NULL, calling itself recursively and hitting the stack guard page. To avoid the issue, let's set the destructor after kzalloc().

If we look up the kbuf, ensure that it doesn't get unregistered until after we're done with it. Since we're inside mmap, we cannot safely use the io_uring lock. Rely on the fact that we can lookup the buffer list under RCU now and grab a reference to it, preventing it from being unregistered until we're done with it. The lookup returns the io_buffer_list directly with it referenced.

2024-04-03vsock/virtio: fix packet delivery to tap deviceMarco Pinna1-1/+2
Commit 82dfb540aeb2 ("VSOCK: Add virtio vsock vsockmon hooks") added virtio_transport_deliver_tap_pkt() for handing packets to the vsockmon device. However, in virtio_transport_send_pkt_work(), the function is called before actually sending the packet (i.e. before placing it in the virtqueue with virtqueue_add_sgs() and checking whether it returned successfully). Queuing the packet in the virtqueue can fail even multiple times. However, in virtio_transport_deliver_tap_pkt() we deliver the packet to the monitoring tap interface only the first time we call it. This certainly avoids seeing the same packet replicated multiple times in the monitoring interface, but it can show the packet sent with the wrong timestamp or even before we succeed to queue it in the virtqueue. Move virtio_transport_deliver_tap_pkt() after calling virtqueue_add_sgs() and making sure it returned successfully.

2024-04-03ax25: fix use-after-free bugs caused by ax25_ds_del_timerDuoming Zhou1-1/+1
When the ax25 device is detaching, the ax25_dev_device_down() calls ax25_ds_del_timer() to cleanup the slave_timer. When the timer handler is running, the ax25_ds_del_timer() that calls del_timer() in it will return directly. As a result, the use-after-free bugs could happen, one of the scenarios is shown below: (Thread 1) | (Thread 2) | ax25_ds_timeout() ax25_dev_device_down() | ax25_ds_del_timer() | del_timer() | ax25_dev_put() //FREE | | ax25_dev-> //USE In order to mitigate bugs, when the device is detaching, use timer_shutdown_sync() to stop the timer.
