2024-05-27af_unix: Read sk->sk_hash under bindlock during bind().Kuniyuki Iwashima
syzkaller reported data-race of sk->sk_hash in unix_autobind() [0], and the same ones exist in unix_bind_bsd() and unix_bind_abstract(). The three bind() functions prefetch sk->sk_hash locklessly and use it later after validating that unix_sk(sk)->addr is NULL under unix_sk(sk)->bindlock. The prefetched sk->sk_hash is the hash value of unbound socket set in unix_create1() and does not change until bind() completes. There could be a chance that sk->sk_hash changes after the lockless read. However, in such a case, non-NULL unix_sk(sk)->addr is visible under unix_sk(sk)->bindlock, and bind() returns -EINVAL without using the prefetched value. The KCSAN splat is false-positive, but let's silence it by reading sk->sk_hash under unix_sk(sk)->bindlock.

2024-05-27af_unix: Annotate data-race around unix_sk(sk)->addr.Kuniyuki Iwashima
Once unix_sk(sk)->addr is assigned under net->unx.table.locks and unix_sk(sk)->bindlock, *(unix_sk(sk)->addr) and unix_sk(sk)->path are fully set up, and unix_sk(sk)->addr is never changed. unix_getname() and unix_copy_addr() access the two fields locklessly, and commit ae3b564179bf ("missing barriers in some of unix_sock ->addr and ->path accesses") added smp_store_release() and smp_load_acquire() pairs. In other functions, we still read unix_sk(sk)->addr locklessly to check if the socket is bound, and KCSAN complains about it. [0] Given these functions have no dependency for *(unix_sk(sk)->addr) and unix_sk(sk)->path, READ_ONCE() is enough to annotate the data-race. Note that it is safe to access unix_sk(sk)->addr locklessly if the socket is found in the hash table. For example, the lockless read of otheru->addr in unix_stream_connect() is safe. Note also that newu->addr there is of the child socket that is still not accessible from userspace, and smp_store_release() publishes the address in case the socket is accept()ed and unix_getname() / unix_copy_addr() is called.

2024-05-27platform/x86: touchscreen_dmi: Add support for setting touchscreen ↵Hans de Goede
properties from cmdline On x86/ACPI platforms touchscreens mostly just work without needing any device/model specific configuration. But in some cases (mostly with Silead and Goodix touchscreens) it is still necessary to manually specify various touchscreen-properties on a per model basis. touchscreen_dmi is a special place for DMI quirks for this, but it can be challenging for users to figure out the right property values, especially for Silead touchscreens where non of these can be read back from the touchscreen-controller. ATM users can only test touchscreen properties by editing touchscreen_dmi.c and then building a completely new kernel which makes it unnecessary difficult for users to test and submit properties when necessary for their laptop / tablet model. Add support for specifying properties on the kernel commandline to allow users to easily figure out the right settings. See the added documentation in kernel-parameters.txt for the commandline syntax.

2024-05-27enic: Validate length of nl attributes in enic_set_vf_portRoded Zats
enic_set_vf_port assumes that the nl attribute IFLA_PORT_PROFILE is of length PORT_PROFILE_MAX and that the nl attributes IFLA_PORT_INSTANCE_UUID, IFLA_PORT_HOST_UUID are of length PORT_UUID_MAX. These attributes are validated (in the function do_setlink in rtnetlink.c) using the nla_policy ifla_port_policy. The policy defines IFLA_PORT_PROFILE as NLA_STRING, IFLA_PORT_INSTANCE_UUID as NLA_BINARY and IFLA_PORT_HOST_UUID as NLA_STRING. That means that the length validation using the policy is for the max size of the attributes and not on exact size so the length of these attributes might be less than the sizes that enic_set_vf_port expects. This might cause an out of bands read access in the memcpys of the data of these attributes in enic_set_vf_port.

2024-05-27ata: ahci: Do not apply Intel PCS quirk on Intel Alder LakeJason Nader
Commit b8b8b4e0c052 ("ata: ahci: Add Intel Alder Lake-P AHCI controller to low power chipsets list") added Intel Alder Lake to the ahci_pci_tbl. Because of the way that the Intel PCS quirk was implemented, having an explicit entry in the ahci_pci_tbl caused the Intel PCS quirk to be applied. (The quirk was not being applied if there was no explict entry.) Thus, entries that were added to the ahci_pci_tbl also got the Intel PCS quirk applied. The quirk was cleaned up in commit 7edbb6059274 ("ahci: clean up intel_pcs_quirk"), such that it is clear which entries that actually applies the Intel PCS quirk. Newer Intel AHCI controllers do not need the Intel PCS quirk, and applying it when not needed actually breaks some platforms. Do not apply the Intel PCS quirk for Intel Alder Lake. This is in line with how things worked before commit b8b8b4e0c052 ("ata: ahci: Add Intel Alder Lake-P AHCI controller to low power chipsets list"), such that certain platforms using Intel Alder Lake will work once again.

2024-05-27ALSA: core: Remove debugfs at disconnectionTakashi Iwai
The card-specific debugfs entries are removed at the last stage of card free phase, and it's performed after synchronization of the closes of all opened fds. This works fine for most cases, but it can be potentially problematic for a hotplug device like USB-audio. Due to the nature of snd_card_free_when_closed(), the card free isn't called immediately after the driver removal for a hotplug device, but it's left until the last fd is closed. It implies that the card debugfs entries also remain. Meanwhile, when a new device is inserted before the last close and the very same card slot is assigned, the driver tries to create the card debugfs root again on the very same path. This conflicts with the remaining entry, and results in the kernel warning such as: debugfs: Directory 'card0' with parent 'sound' already present! with the missing debugfs entry afterwards. For avoiding such conflicts, remove debugfs entries at the device disconnection phase instead. The jack kctl debugfs entries get removed in snd_jack_dev_disconnect() instead of each kctl private_free.

2024-05-27regmap-i2c: Subtract reg size from max_writeJim Wylder
Currently, when an adapter defines a max_write_len quirk, the data will be chunked into data sizes equal to the max_write_len quirk value. But the payload will be increased by the size of the register address before transmission. The resulting value always ends up larger than the limit set by the quirk. Avoid this error by setting regmap's max_write to the quirk's max_write_len minus the number of bytes for the register and padding. This allows the chunking to work correctly for this limited case without impacting other use-cases.

2024-05-26hwrng: core - Remove add_early_randomnessHerbert Xu
A potential deadlock was reported with the config file at https://web.archive.org/web/20240522052129/https://0x0.st/XPN_.txt In this particular configuration, the deadlock doesn't exist because the warning triggered at a point before modules were even available. However, the deadlock can be real because any module loaded would invoke async_synchronize_full. The issue is spurious for software crypto algorithms which aren't themselves involved in async probing. However, it would be hard to avoid for a PCI crypto driver using async probing. In this particular call trace, the problem is easily avoided because the only reason the module is being requested during probing is the add_early_randomness call in the hwrng core. This feature is vestigial since there is now a kernel thread dedicated to doing exactly this. So remove add_early_randomness as it is no longer needed. Reported-by: Nícolas F. R. A.

2024-05-25netkit: Fix pkt_type override upon netkit pass verdictDaniel Borkmann
When running Cilium connectivity test suite with netkit in L2 mode, we found that compared to tcx a few tests were failing which pushed traffic into an L7 proxy sitting in host namespace. The problem in particular is around the invocation of eth_type_trans() in netkit. In case of tcx, this is run before the tcx ingress is triggered inside host namespace and thus if the BPF program uses the bpf_skb_change_type() helper the newly set type is retained. However, in case of netkit, the late eth_type_trans() invocation overrides the earlier decision from the BPF program which eventually leads to the test failure. Instead of eth_type_trans(), split out the relevant parts, meaning, reset of mac header and call to eth_skb_pkt_type() before the BPF program is run in order to have the same behavior as with tcx, and refactor a small helper called eth_skb_pull_mac() which is run in case it's passed up the stack where the mac header must be pulled. With this all connectivity tests pass.

This checks correct libbpf fallback to singular uprobes (when run on older kernels with buggy PID filtering).

Extend existing multi-uprobe tests to test that PID filtering works correctly. We already have child *process* tests, but we need also child *thread* tests. This patch adds spawn_thread() helper to start child thread, wait for it to be ready, and then instruct it to trigger desired uprobes. Additionally, we extend BPF-side code to track thread ID, not just process ID. Also we detect whether extraneous triggerings with unexpected process IDs happened, and validate that none of that happened in practice. These changes prove that fixed PID filtering logic for multi-uprobe works as expected. These tests fail on old kernels.

2024-05-25libbpf: detect broken PID filtering logic for multi-uprobeAndrii Nakryiko
Libbpf is automatically (and transparently to user) detecting multi-uprobe support in the kernel, and, if supported, uses multi-uprobes to improve USDT attachment speed. USDTs can be attached system-wide or for the specific process by PID. In the latter case, we rely on correct kernel logic of not triggering USDT for unrelated processes. As such, on older kernels that do support multi-uprobes, but still have broken PID filtering logic, we need to fall back to singular uprobes. Unfortunately, whether user is using PID filtering or not is known at the attachment time, which happens after relevant BPF programs were loaded into the kernel. Also unfortunately, we need to make a call whether to use multi-uprobes or singular uprobe for SEC("usdt") programs during BPF object load time, at which point we have no information about possible PID filtering. The distinction between single and multi-uprobes is small, but important for the kernel. Multi-uprobes get BPF_TRACE_UPROBE_MULTI attach type, and kernel internally substitiute different implementation of some of BPF helpers (e.g., bpf_get_attach_cookie()) depending on whether uprobe is multi or singular. So, multi-uprobes and singular uprobes cannot be intermixed. All the above implies that we have to make an early and conservative call about the use of multi-uprobes. And so this patch modifies libbpf's existing feature detector for multi-uprobe support to also check correct PID filtering. If PID filtering is not yet fixed, we fall back to singular uprobes for USDTs. This extension to feature detection is simple thanks to kernel's -EINVAL addition for pid < 0.

2024-05-25bpf: fix multi-uprobe PID filtering logicAndrii Nakryiko
Current implementation of PID filtering logic for multi-uprobes in uprobe_prog_run() is filtering down to exact *thread*, while the intent for PID filtering it to filter by *process* instead. The check in uprobe_prog_run() also differs from the analogous one in uprobe_multi_link_filter() for some reason. The latter is correct, checking task->mm, not the task itself. Fix the check in uprobe_prog_run() to perform the same task->mm check. While doing this, we also update get_pid_task() use to use PIDTYPE_TGID type of lookup, given the intent is to get a representative task of an entire process. This doesn't change behavior, but seems more logical. It would hold task group leader task now, not any random thread task. Last but not least, given multi-uprobe support is half-broken due to this PID filtering logic (depending on whether PID filtering is important or not), we need to make it easy for user space consumers (including libbpf) to easily detect whether PID filtering logic was already fixed. We do it here by adding an early check on passed pid parameter. If it's negative (and so has no chance of being a valid PID), we return -EINVAL. Previous behavior would eventually return -ESRCH ("No process found"), given there can't be any process with negative PID. This subtle change won't make any practical change in behavior, but will allow applications to detect PID filtering fixes easily. Libbpf fixes take advantage of this in the next patch.

2024-05-25afs: Don't cross .backup mountpoint from backup volumeMarc Dionne
Don't cross a mountpoint that explicitly specifies a backup volume (target is <vol>.backup) when starting from a backup volume. It it not uncommon to mount a volume's backup directly in the volume itself. This can cause tools that are not paying attention to get into a loop mounting the volume onto itself as they attempt to traverse the tree, leading to a variety of problems. This doesn't prevent the general case of loops in a sequence of mountpoints, but addresses a common special case in the same way as other afs clients.
