2023-01-30ublk_drv: add mechanism for supporting unprivileged ublk deviceMing Lei1-2/+34
unprivileged ublk device is helpful for container use case, such as: ublk device created in one unprivileged container can be controlled and accessed by this container only. Implement this feature by adding flag of UBLK_F_UNPRIVILEGED_DEV, and if this flag isn't set, any control command has been run from privileged user. Otherwise, any control command can be sent from any unprivileged user, but the user has to be permitted to access the ublk char device to be controlled. In case of UBLK_F_UNPRIVILEGED_DEV: 1) for command UBLK_CMD_ADD_DEV, it is always allowed, and user needs to provide owner's uid/gid in this command, so that udev can set correct ownership for the created ublk device, since the device owner uid/gid can be queried via command of UBLK_CMD_GET_DEV_INFO. 2) for other control commands, they can only be run successfully if the current user is allowed to access the specified ublk char device, for running the permission check, path of the ublk char device has to be provided by these commands. Also add one control of command UBLK_CMD_GET_DEV_INFO2 which always include the char dev path in payload since userspace may not have knowledge if this device is created in unprivileged mode. For applying this mechanism, system administrator needs to take the following policies: 1) chmod 0666 /dev/ublk-control 2) change ownership of ublkcN & ublkbN - chown owner_uid:owner_gid /dev/ublkcN - chown owner_uid:owner_gid /dev/ublkbN Both can be done via one simple udev rule. Userspace: https://github.com/ming1/ubdsrv/tree/unprivileged-ublk 'ublk add -t $TYPE --un_privileged=1' is for creating one un-privileged ublk device if the user is un-privileged.

With major/minor, it is easy to find the device node path.

2023-01-30block: save user max_sectors limitKeith Busch1-0/+1
The user can set the max_sectors limit to any valid value via sysfs /sys/block/<dev>/queue/max_sectors_kb attribute. If the device limits are ever rescanned, though, the limit reverts back to the potentially artificially low BLK_DEF_MAX_SECTORS value. Preserve the user's setting as the max_sectors limit as long as it's valid. The user can reset back to defaults by writing 0 to the sysfs file.

2023-01-24platform/x86: apple-gmux: Add apple_gmux_detect() helperHans de Goede1-2/+84
Add a new (static inline) apple_gmux_detect() helper to apple-gmux.h which can be used for gmux detection instead of apple_gmux_present(). The latter is not really reliable since an ACPI device with a HID of APP000B is present on some devices without a gmux at all, as well as on devices with a newer (unsupported) MMIO based gmux model. This causes apple_gmux_present() to return false-positives on a number of different Apple laptop models. This new helper uses the same probing as the actual apple-gmux driver, so that it does not return false positives. To avoid code duplication the gmux_probe() function of the actual driver is also moved over to using the new apple_gmux_detect() helper. This avoids false positives (vs _HID + IO region detection) on: MacBookPro5,4 https://pastebin.com/8Xjq7RhS MacBookPro8,1 https://linux-hardware.org/?probe=e513cfbadb&log=dmesg MacBookPro9,2 https://bugzilla.kernel.org/attachment.cgi?id=278961 MacBookPro10,2 https://lkml.org/lkml/2014/9/22/657 MacBookPro11,2 https://forums.fedora-fr.org/viewtopic.php?id=70142 MacBookPro11,4 https://raw.githubusercontent.com/im-0/investigate-card-reader-suspend-problem-on-mbp11.4/master/test-16/dmesg Fixes: 21245df307cb ("ACPI: video: Add Apple GMUX brightness control detection") Link: https://lore.kernel.org/platform-driver-x86/20230123113750.462144-1-hdegoede@redhat.com/ Reported-by: Emmanouil Kouroupakis <kartebi@gmail.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Link: https://lore.kernel.org/r/20230124105754.62167-3-hdegoede@redhat.com

2023-01-24drm/fb-helper: Use a per-driver FB deferred I/O handlerJavier Martinez Canillas1-0/+12
The DRM fbdev emulation layer sets the struct fb_info .fbdefio field to a struct fb_deferred_io pointer, that is shared across all drivers that use the generic drm_fbdev_generic_setup() helper function. It is a problem because the fbdev core deferred I/O logic assumes that the struct fb_deferred_io data is not shared between devices, and it's stored there state such as the list of pages touched and a mutex that is use to synchronize between the fb_deferred_io_track_page() function that track the dirty pages and fb_deferred_io_work() workqueue handler doing the actual deferred I/O. The latter can lead to the following error, since it may happen that two drivers are probed and then one is removed, which causes the mutex bo be destroyed and not existing anymore by the time the other driver tries to grab it for the fbdev deferred I/O logic: [ 369.756553] ------------[ cut here ]------------ [ 369.756604] DEBUG_LOCKS_WARN_ON(lock->magic != lock) [ 369.756631] WARNING: CPU: 2 PID: 1023 at kernel/locking/mutex.c:582 __mutex_lock+0x348/0x424 [ 369.756744] Modules linked in: nf_conntrack_netbios_ns nf_conntrack_broadcast nft_fib_inet nft_fib_ipv4 nft_fib_ipv6 nft_fib nft_reject_inet nf_reject_ipv4 nf_reject_ipv6 nft_reject nft_ct nft_chain_nat nf_nat nf_conntrack nf_defrag_ip v6 nf_defrag_ipv4 ip_set nf_tables nfnetlink qrtr btsdio bluetooth sunrpc brcmfmac snd_soc_hdmi_codec cpufreq_dt cfg80211 vfat fat vc4 rfkill brcmutil raspberrypi_cpufreq i2c_bcm2835 iproc_rng200 bcm2711_thermal snd_soc_core snd_pcm_dmaen gine leds_gpio nvmem_rmem joydev hid_cherry uas usb_storage gpio_raspberrypi_exp v3d snd_pcm raspberrypi_hwmon gpu_sched bcm2835_wdt broadcom bcm_phy_lib snd_timer genet snd mdio_bcm_unimac clk_bcm2711_dvp soundcore drm_display_helper pci e_brcmstb cec ip6_tables ip_tables fuse [ 369.757400] CPU: 2 PID: 1023 Comm: fbtest Not tainted 5.19.0-rc6+ #94 [ 369.757455] Hardware name: raspberrypi,4-model-b Raspberry Pi 4 Model B Rev 1.4/Raspberry Pi 4 Model B Rev 1.4, BIOS 2022.10 10/01/2022 [ 369.757538] pstate: 00400005 (nzcv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) [ 369.757596] pc : __mutex_lock+0x348/0x424 [ 369.757635] lr : __mutex_lock+0x348/0x424 [ 369.757672] sp : ffff80000953bb00 [ 369.757703] x29: ffff80000953bb00 x28: ffff17fdc087c000 x27: 0000000000000002 [ 369.757771] x26: ffff17fdc349f9b0 x25: fffffc5ff72e0100 x24: 0000000000000000 [ 369.757838] x23: 0000000000000000 x22: 0000000000000002 x21: ffffa618df636f10 [ 369.757903] x20: ffff80000953bb68 x19: ffffa618e0f18138 x18: 0000000000000001 [ 369.757968] x17: 0000000020000000 x16: 0000000000000002 x15: 0000000000000000 [ 369.758032] x14: 0000000000000000 x13: 284e4f5f4e524157 x12: 5f534b434f4c5f47 [ 369.758097] x11: 00000000ffffdfff x10: ffffa618e0c79f88 x9 : ffffa618de472484 [ 369.758162] x8 : 000000000002ffe8 x7 : c0000000ffffdfff x6 : 00000000000affa8 [ 369.758227] x5 : 0000000000001fff x4 : 0000000000000000 x3 : 0000000000000027 [ 369.758292] x2 : 0000000000000001 x1 : ffff17fdc087c000 x0 : 0000000000000028 [ 369.758357] Call trace: [ 369.758383] __mutex_lock+0x348/0x424 [ 369.758420] mutex_lock_nested+0x4c/0x5c [ 369.758459] fb_deferred_io_mkwrite+0x78/0x1d8 [ 369.758507] do_page_mkwrite+0x5c/0x19c [ 369.758550] wp_page_shared+0x70/0x1a0 [ 369.758590] do_wp_page+0x3d0/0x510 [ 369.758628] handle_pte_fault+0x1c0/0x1e0 [ 369.758670] __handle_mm_fault+0x250/0x380 [ 369.758712] handle_mm_fault+0x17c/0x3a4 [ 369.758753] do_page_fault+0x158/0x530 [ 369.758792] do_mem_abort+0x50/0xa0 [ 369.758831] el0_da+0x78/0x19c [ 369.758864] el0t_64_sync_handler+0xbc/0x150 [ 369.758904] el0t_64_sync+0x190/0x194 [ 369.758942] irq event stamp: 11395 [ 369.758973] hardirqs last enabled at (11395): [<ffffa618de472554>] __up_console_sem+0x74/0x80 [ 369.759042] hardirqs last disabled at (11394): [<ffffa618de47254c>] __up_console_sem+0x6c/0x80 [ 369.760554] softirqs last enabled at (11392): [<ffffa618de330a74>] __do_softirq+0x4c4/0x6b8 [ 369.762060] softirqs last disabled at (11383): [<ffffa618de3c9124>] __irq_exit_rcu+0x104/0x214 [ 369.763564] ---[ end trace 0000000000000000 ]--- Fixes: d536540f304c ("drm/fb-helper: Add generic fbdev emulation .fb_probe function") Signed-off-by: Javier Martinez Canillas <javierm@redhat.com> Reviewed-by: Thomas Zimmermann <tzimmermann@suse.de> Link: https://patchwork.freedesktop.org/patch/msgid/20230121192418.2814955-4-javierm@redhat.com
2023-01-24netfilter: conntrack: unify established states for SCTP pathsSriram Yagnaraman2-2/+2
An SCTP endpoint can start an association through a path and tear it down over another one. That means the initial path will not see the shutdown sequence, and the conntrack entry will remain in ESTABLISHED state for 5 days. By merging the HEARTBEAT_ACKED and ESTABLISHED states into one ESTABLISHED state, there remains no difference between a primary or secondary path. The timeout for the merged ESTABLISHED state is set to 210 seconds (hb_interval * max_path_retrans + rto_max). So, even if a path doesn't see the shutdown sequence, it will expire in a reasonable amount of time. With this change in place, there is now more than one state from which we can transition to ESTABLISHED, COOKIE_ECHOED and HEARTBEAT_SENT, so handle the setting of ASSURED bit whenever a state change has happened and the new state is ESTABLISHED. Removed the check for dir==REPLY since the transition to ESTABLISHED can happen only in the reply direction. Fixes: 9fb9cbb1082d ("[NETFILTER]: Add nf_conntrack subsystem.")

This reverts commit (bff3d0534804: "netfilter: conntrack: add sctp DATA_SENT state") Using DATA/SACK to detect a new connection on secondary/alternate paths works only on new connections, while a HEARTBEAT is required on connection re-use. It is probably consistent to wait for HEARTBEAT to create a secondary connection in conntrack.

2023-01-19scsi: ufs: core: Fix devfreq deadlocksJohan Hovold1-0/+2
There is a lock inversion and rwsem read-lock recursion in the devfreq target callback which can lead to deadlocks. Specifically, ufshcd_devfreq_scale() already holds a clk_scaling_lock read lock when toggling the write booster, which involves taking the dev_cmd mutex before taking another clk_scaling_lock read lock. This can lead to a deadlock if another thread: 1) tries to acquire the dev_cmd and clk_scaling locks in the correct order, or 2) takes a clk_scaling write lock before the attempt to take the clk_scaling read lock a second time. Fix this by dropping the clk_scaling_lock before toggling the write booster as was done before commit 0e9d4ca43ba8 ("scsi: ufs: Protect some contexts from unexpected clock scaling"). While the devfreq callbacks are already serialised, add a second serialising mutex to handle the unlikely case where a callback triggered through the devfreq sysfs interface is racing with a request to disable clock scaling through the UFS controller 'clkscale_enable' sysfs attribute. This could otherwise lead to the write booster being left disabled after having disabled clock scaling. Also take the new mutex in ufshcd_clk_scaling_allow() to make sure that any pending write booster update has completed on return. Note that this currently only affects Qualcomm platforms since commit 87bd05016a64 ("scsi: ufs: core: Allow host driver to disable wb toggling during clock scaling"). The lock inversion (i.e. 1 above) was reported by lockdep as: ====================================================== WARNING: possible circular locking dependency detected 6.1.0-next-20221216 #211 Not tainted ------------------------------------------------------ kworker/u16:2/71 is trying to acquire lock: ffff076280ba98a0 (&hba->dev_cmd.lock){+.+.}-{3:3}, at: ufshcd_query_flag+0x50/0x1c0 but task is already holding lock: ffff076280ba9cf0 (&hba->clk_scaling_lock){++++}-{3:3}, at: ufshcd_devfreq_scale+0x2b8/0x380 which lock already depends on the new lock.

2023-01-17USB: fix misleading usb_set_intfdata() kernel docJohan Hovold1-8/+7
The struct device driver-data pointer is used for any data that a driver may need in various callbacks while bound to the device. For convenience, subsystems typically provide wrappers such as usb_set_intfdata() of the generic accessor functions for use in bus callbacks. There is generally no longer any need for a driver to clear the pointer, but since commit 0998d0631001 ("device-core: Ensure drvdata = NULL when no driver is bound") the driver-data pointer is set to NULL by driver core post unbind anyway. For historical reasons, USB core also clears this pointer when an explicitly claimed interface is released. Due to a misunderstanding, a misleading kernel doc comment for usb_set_intfdata() was recently added which claimed that the driver data pointer must not be cleared during disconnect before "all actions [are] completed", which is both imprecise and incorrect. Specifically, drivers like cdc-acm which claim additional interfaces use the driver-data pointer as a flag which is cleared when the first interface is unbound. As long as a driver does not do something odd like dereference the pointer in, for example, completion callbacks, this can be done at any time during disconnect. And in any case this is no different than for any other resource, like the driver data itself, which may be freed by the disconnect callback. Note that the comment actually also claimed that the interface itself was somehow being set to NULL by driver core. Fix the kernel doc by removing incorrect, overly specific and misleading details and adding a comment about why some drivers do clear the driver-data pointer.

2023-01-16net/sched: sch_taprio: fix possible use-after-freeEric Dumazet1-0/+7
syzbot reported a nasty crash [1] in net_tx_action() which made little sense until we got a repro. This repro installs a taprio qdisc, but providing an invalid TCA_RATE attribute. qdisc_create() has to destroy the just initialized taprio qdisc, and taprio_destroy() is called. However, the hrtimer used by taprio had already fired, therefore advance_sched() called __netif_schedule(). Then net_tx_action was trying to use a destroyed qdisc. We can not undo the __netif_schedule(), so we must wait until one cpu serviced the qdisc before we can proceed. Many thanks to Alexander Potapenko for his help.

2023-01-13efi: tpm: Avoid READ_ONCE() for accessing the event logArd Biesheuvel1-2/+2
Nathan reports that recent kernels built with LTO will crash when doing EFI boot using Fedora's GRUB and SHIM. The culprit turns out to be a misaligned load from the TPM event log, which is annotated with READ_ONCE(), and under LTO, this gets translated into a LDAR instruction which does not tolerate misaligned accesses. Interestingly, this does not happen when booting the same kernel straight from the UEFI shell, and so the fact that the event log may appear misaligned in memory may be caused by a bug in GRUB or SHIM. However, using READ_ONCE() to access firmware tables is slightly unusual in any case, and here, we only need to ensure that 'event' is not dereferenced again after it gets unmapped, but this is already taken care of by the implicit barrier() semantics of the early_memunmap() call.

git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 fixes from Will Deacon: "Here's a sizeable batch of Friday the 13th arm64 fixes for -rc4. What could possibly go wrong? The obvious reason we have so much here is because of the holiday season right after the merge window, but we've also brought back an erratum workaround that was previously dropped at the last minute and there's an MTE coredumping fix that strays outside of the arch/arm64 directory. Summary: - Fix PAGE_TABLE_CHECK failures on hugepage splitting path - Fix PSCI encoding of MEM_PROTECT_RANGE function in UAPI header - Fix NULL deref when accessing debugfs node if PSCI is not present - Fix MTE core dumping when VMA list is being updated concurrently - Fix SME signal frame handling when SVE is not implemented by the CPU - Fix asm constraints for cmpxchg_double() to hazard both words - Fix build failure with stack tracer and older versions of Clang - Bring back workaround for Cortex-A715 erratum 2645198" * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64: Fix build with CC=clang, CONFIG_FTRACE=y and CONFIG_STACK_TRACER=y arm64/mm: Define dummy pud_user_exec() when using 2-level page-table arm64: errata: Workaround possible Cortex-A715 [ESR|FAR]_ELx corruption firmware/psci: Don't register with debugfs if PSCI isn't available firmware/psci: Fix MEM_PROTECT_RANGE function numbers arm64/signal: Always allocate SVE signal frames on SME only systems arm64/signal: Always accept SVE signal frames on SME only systems arm64/sme: Fix context switch for SME only systems arm64: cmpxchg_double*: hazard against entire exchange variable arm64/uprobes: change the uprobe_opcode_t typedef to fix the sparse warning arm64: mte: Avoid the racy walk of the vma list during core dump elfcore: Add a cprm parameter to elf_core_extra_{phdrs,data_size} arm64: mte: Fix double-freeing of the temporary tag storage during coredump arm64: ptrace: Use ARM64_SME to guard the SME register enumerations arm64/mm: add pud_user_exec() check in pud_user_accessible_page() arm64/mm: fix incorrect file_map_count for invalid pmd
