2023-05-01driver core: Don't require dynamic_debug for initcall_debug probe timingStephen Boyd1-1/+6
commit e2f06aa885081e1391916367f53bad984714b4db upstream. Don't require the use of dynamic debug (or modification of the kernel to add a #define DEBUG to the top of this file) to get the printk message about driver probe timing. This printk is only emitted when initcall_debug is enabled on the kernel commandline, and it isn't immediately obvious that you have to do something else to debug boot timing issues related to driver probe. Add a comment too so it doesn't get converted back to pr_debug().

2023-05-01mm/mremap: fix vm_pgoff in vma_merge() case 3Vlastimil Babka1-1/+1
commit 7e7757876f258d99266e7b3c559639289a2a45fe upstream. After upgrading build guests to v6.3, rpm started segfaulting for specific packages, which was bisected to commit 0503ea8f5ba7 ("mm/mmap: remove __vma_adjust()"). rpm is doing many mremap() operations with file mappings of its db. The problem is that in vma_merge() case 3 (we merge with the next vma, expanding it downwards) vm_pgoff is not adjusted as it should when vm_start changes. As a result the rpm process most likely sees data from the wrong offset of the file. Fix the vm_pgoff calculation. For case 8 this is a non-functional change as the resulting vm_pgoff is the same.

2023-05-01wifi: brcmfmac: add Cypress 43439 SDIO idsMarek Vasut2-2/+12
commit cc4cffc3c142d57df48c07851862444e1d33bdaa upstream. Add SDIO ids for use with the muRata 1YN (Cypress CYW43439). The odd thing about this is that the previous 1YN populated on M.2 card for evaluation purposes had BRCM SDIO vendor ID, while the chip populated on real hardware has a Cypress one. The device ID also differs between the two devices. But they are both 43439 otherwise, so add the IDs for both. On-device 1YN (43439), the new one, chip label reads "1YN": ``` /sys/.../mmc_host/mmc2/mmc2:0001 # cat vendor device 0x04b4 0xbd3d ``` EA M.2 evaluation board 1YN (43439), the old one, chip label reads "1YN ES1.4": ``` /sys/.../mmc_host/mmc0/mmc0:0001/# cat vendor device 0x02d0 0xa9a6 ``` Reviewed-by: Hans de Goede <hdegoede@redhat.com> Cc: stable@vger.kernel.org Signed-off-by: Marek Vasut <marex@denx.de> Reviewed-by: Simon Horman <simon.horman@corigine.com> Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://lore.kernel.org/r/20230407203752.128539-1-marex@denx.de Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2023-05-01bluetooth: Perform careful capability checks in hci_sock_ioctl()Ruihan Li1-1/+8
commit 25c150ac103a4ebeed0319994c742a90634ddf18 upstream. Previously, capability was checked using capable(), which verified that the caller of the ioctl system call had the required capability. In addition, the result of the check would be stored in the HCI_SOCK_TRUSTED flag, making it persistent for the socket. However, malicious programs can abuse this approach by deliberately sharing an HCI socket with a privileged task. The HCI socket will be marked as trusted when the privileged task occasionally makes an ioctl call. This problem can be solved by using sk_capable() to check capability, which ensures that not only the current task but also the socket opener has the specified capability, thus reducing the risk of privilege escalation through the previously identified vulnerability.

2023-05-01gpiolib: acpi: Add a ignore wakeup quirk for Clevo NL5xNUWerner Sembach1-0/+13
commit 782eea0c89f7d071d6b56ecfa1b8b0c81164b9be upstream. commit 1796f808e4bb ("HID: i2c-hid: acpi: Stop setting wakeup_capable") changed the policy such that I2C touchpads may be able to wake up the system by default if the system is configured as such. However on Clevo NL5xNU there is a mistake in the ACPI tables that the TP_ATTN# signal connected to GPIO 9 is configured as ActiveLow and level triggered but connected to a pull up. As soon as the system suspends the touchpad loses power and then the system wakes up. To avoid this problem, introduce a quirk for this model that will prevent the wakeup capability for being set for GPIO 9. This patch is analoge to a very similar patch for NL5xRU, just the DMI string changed.

2023-05-01fsverity: explicitly check for buffer overflow in build_merkle_tree()Eric Biggers1-0/+10
commit 39049b69ec9fc125fa1f314165dcc86f72cb72ec upstream. The new Merkle tree construction algorithm is a bit fragile in that it may overflow the 'root_hash' array if the tree actually generated does not match the calculated tree parameters. This should never happen unless there is a filesystem bug that allows the file size to change despite deny_write_access(), or a bug in the Merkle tree logic itself. Regardless, it's fairly easy to check for buffer overflow here, so let's do so. This is a robustness improvement only; this case is not currently known to be reachable. I've added a Fixes tag anyway, since I recommend that this be included in kernels that have the mentioned commit.

2023-05-01fsverity: reject FS_IOC_ENABLE_VERITY on mode 3 fdsEric Biggers1-0/+7
commit 04839139213cf60d4c5fc792214a08830e294ff8 upstream. Commit 56124d6c87fd ("fsverity: support enabling with tree block size < PAGE_SIZE") changed FS_IOC_ENABLE_VERITY to use __kernel_read() to read the file's data, instead of direct pagecache accesses. An unintended consequence of this is that the 'WARN_ON_ONCE(!(file->f_mode & FMODE_READ))' in __kernel_read() became reachable by fuzz tests. This happens if FS_IOC_ENABLE_VERITY is called on a fd opened with access mode 3, which means "ioctl access only". Arguably, FS_IOC_ENABLE_VERITY should work on ioctl-only fds. But ioctl-only fds are a weird Linux extension that is rarely used and that few people even know about. (The documentation for FS_IOC_ENABLE_VERITY even specifically says it requires O_RDONLY.) It's probably not worthwhile to make the ioctl internally open a new fd just to handle this case. Thus, just reject the ioctl on such fds for now.

2023-04-23gcc: disable '-Warray-bounds' for gcc-13 tooLinus Torvalds1-7/+3
We started disabling '-Warray-bounds' for gcc-12 originally on s390, because it resulted in some warnings that weren't realistically fixable (commit 8b202ee21839: "s390: disable -Warray-bounds"). That s390-specific issue was then found to be less common elsewhere, but generic (see f0be87c42cbd: "gcc-12: disable '-Warray-bounds' universally for now"), and then later expanded the version check was expanded to gcc-11 (5a41237ad1d4: "gcc: disable -Warray-bounds for gcc-11 too"). And it turns out that I was much too optimistic in thinking that it's all going to go away, and here we are with gcc-13 showing all the same issues. So instead of expanding this one version at a time, let's just disable it for gcc-11+, and put an end limit to it only when we actually find a solution. Yes, I'm sure some of this is because the kernel just does odd things (like our "container_of()" use, but also knowingly playing games with things like linker tables and array layouts). And yes, some of the warnings are likely signs of real bugs, but when there are hundreds of false positives, that doesn't really help. Oh well.

2023-04-23kbuild: use proper prefix for tarballs to fix rpm-pkg build errorMasahiro Yamada1-3/+3
Since commit f8d94c4e403c ("kbuild: do not create intermediate *.tar for source tarballs"), 'make rpm-pkg' fails because the prefix of the source tarball is 'linux.tar/' instead of 'linux/'. $(basename $@) strips only '.gz' from the filename linux.tar.gz. You need to strip two suffixes from compressed tarballs and one suffix from uncompressed tarballs (for example 'perf-6.3.0.tar' generated by 'make perf-tar-src-pkg'). One tricky fix might be --prefix=$(firstword $(subst .tar, ,$@))/ but I think it is better to hard-code the prefix.

2023-04-21btrfs: reinterpret async discard iops_limit=0 as no delayBoris Burkov1-7/+12
Currently, a limit of 0 results in a hard coded metering over 6 hours. Since the default is a set limit, I suspect no one truly depends on this rather arbitrary setting. Repurpose it for an arguably more useful "unlimited" mode, where the delay is 0. Note that if block groups are too new, or go fully empty, there is still a delay associated with those conditions. Those delays implement heuristics for not trimming a region we are relatively likely to fully overwrite soon.

2023-04-21btrfs: set default discard iops_limit to 1000Boris Burkov1-1/+1
Previously, the default was a relatively conservative 10. This results in a 100ms delay, so with ~300 discards in a commit, it takes the full 30s till the next commit to finish the discards. On a workstation, this results in the disk never going idle, wasting power/battery, etc. Set the default to 1000, which results in using the smallest possible delay, currently, which is 1ms. This has shown to not pathologically keep the disk busy by the original reporter.

Turns out the channelmap variable is not actually read-only, it's modified through the MCI_GPM_CLR_CHANNEL_BIT() macro further down in the function, so making it read-only causes page faults when that code is hit.

2023-04-20PCI: Restrict device disabled status check to DTRob Herring3-12/+30
Commit 6fffbc7ae137 ("PCI: Honor firmware's device disabled status") checked the firmware device status for both DT and ACPI devices. That caused a regression in some ACPI systems. The exact reason isn't clear. It's possibly a firmware bug. For now, at least, refactor the check to be for DT based systems only. Note that the original implementation leaked a refcount which is now correctly handled.

2023-04-20net: bridge: switchdev: don't notify FDB entries with "master dynamic"Vladimir Oltean1-0/+11
There is a structural problem in switchdev, where the flag bits in struct switchdev_notifier_fdb_info (added_by_user, is_local etc) only represent a simplified / denatured view of what's in struct net_bridge_fdb_entry :: flags (BR_FDB_ADDED_BY_USER, BR_FDB_LOCAL etc). Each time we want to pass more information about struct net_bridge_fdb_entry :: flags to struct switchdev_notifier_fdb_info (here, BR_FDB_STATIC), we find that FDB entries were already notified to switchdev with no regard to this flag, and thus, switchdev drivers had no indication whether the notified entries were static or not. For example, this command: ip link add br0 type bridge && ip link set swp0 master br0 bridge fdb add dev swp0 00:01:02:03:04:05 master dynamic has never worked as intended with switchdev. It causes a struct net_bridge_fdb_entry to be passed to br_switchdev_fdb_notify() which has a single flag set: BR_FDB_ADDED_BY_USER. This is further passed to the switchdev notifier chain, where interested drivers have no choice but to assume this is a static (does not age) and sticky (does not migrate) FDB entry. So currently, all drivers offload it to hardware as such, as can be seen below ("offload" is set). bridge fdb get 00:01:02:03:04:05 dev swp0 master 00:01:02:03:04:05 dev swp0 offload master br0 The software FDB entry expires $ageing_time centiseconds after the kernel last sees a packet with this MAC SA, and the bridge notifies its deletion as well, so it eventually disappears from hardware too. This is a problem, because it is actually desirable to start offloading "master dynamic" FDB entries correctly - they should expire $ageing_time centiseconds after the *hardware* port last sees a packet with this MAC SA - and this is how the current incorrect behavior was discovered. With an offloaded data plane, it can be expected that software only sees exception path packets, so an otherwise active dynamic FDB entry would be aged out by software sooner than it should. With the change in place, these FDB entries are no longer offloaded: bridge fdb get 00:01:02:03:04:05 dev swp0 master 00:01:02:03:04:05 dev swp0 master br0 and this also constitutes a better way (assuming a backport to stable kernels) for user space to determine whether the kernel has the capability of doing something sane with these or not. As opposed to "master dynamic" FDB entries, on the current behavior of which no one currently depends on (which can be deduced from the lack of kselftests), Ido Schimmel explains that entries with the "extern_learn" flag (BR_FDB_ADDED_BY_EXT_LEARN) should still be notified to switchdev, since the spectrum driver listens to them (and this is kind of okay, because although they are treated identically to "static", they are expected to not age, and to roam).
