[ Upstream commit f78bbcae ] When binding the function to usb_configuration, check whether the thread is running before starting another one. Without that, when function instance is added to multiple configurations, fsg_bing starts multiple threads with all but the latest one being forgotten by the driver. This leads to obvious thread leaks, possible lockups when trying to halt the machine and possible more issues. This fixes issues with legacy/multi¹ gadget as well as configfs gadgets when mass_storage function is added to multiple configurations. This change also simplifies API since the legacy gadgets no longer need to worry about starting the thread by themselves (which was where bug in legacy/multi was in the first place). N.B., this patch doesn’t address adding single mass_storage function instance to a single configuration twice. Thankfully, there’s no legitimate reason for such setup plus, if I’m not mistaken, configfs gadget doesn’t even allow it to be expressed. ¹ I have no example failure though. Conclusion that legacy/multi has a bug is based purely on me reading the code.

[ Upstream commit 5542f58c ] Use device_is_registered() instad of sysfs flag to determine if we should free sysfs representation of particular LUN. sysfs flag in fsg common determines if luns attributes should be exposed using sysfs. This flag is used when creating and freeing luns. Unfortunately there is no guarantee that this flag will not be changed between creation and removal of particular LUN. Especially because of lun.0 which is created during allocating instance of function. This may lead to resource leak or NULL pointer dereference: [ 62.539925] Unable to handle kernel NULL pointer dereference at virtual address 00000044 [ 62.548014] pgd = ec994000 [ 62.550679] [00000044] *pgd=6d7be831, *pte=00000000, *ppte=00000000 [ 62.556933] Internal error: Oops: 17 [#1] PREEMPT SMP ARM [ 62.562310] Modules linked in: g_mass_storage(+) [ 62.566916] CPU: 2 PID: 613 Comm: insmod Not tainted 4.2.0-rc4-00077-ge29ee91-dirty #125 [ 62.574984] Hardware name: SAMSUNG EXYNOS (Flattened Device Tree) [ 62.581061] task: eca56e80 ti: eca76000 task.ti: eca76000 [ 62.586450] PC is at kernfs_find_ns+0x8/0xe8 [ 62.590698] LR is at kernfs_find_and_get_ns+0x30/0x48 [ 62.595732] pc : [<c01277c0>] lr : [<c0127b88>] psr: 40010053 [ 62.595732] sp : eca77c40 ip : eca77c38 fp : 000008c1 [ 62.607187] r10: 00000001 r9 : c0082f38 r8 : ed41ce40 [ 62.612395] r7 : c05c1484 r6 : 00000000 r5 : 00000000 r4 : c0814488 [ 62.618904] r3 : 00000000 r2 : 00000000 r1 : c05c1484 r0 : 00000000 [ 62.625417] Flags: nZcv IRQs on FIQs off Mode SVC_32 ISA ARM Segment user [ 62.632620] Control: 10c5387d Table: 6c99404a DAC: 00000015 [ 62.638348] Process insmod (pid: 613, stack limit = 0xeca76210) [ 62.644251] Stack: (0xeca77c40 to 0xeca78000) [ 62.648594] 7c40: c0814488 00000000 00000000 c05c1484 ed41ce40 c0127b88 00000000 c0824888 [ 62.656753] 7c60: ed41d038 ed41d030 ed41d000 c012af4c 00000000 c0824858 ed41d038 c02e3314 [ 62.664912] 7c80: ed41d030 00000000 ed41ce04 c02d9e8c c070eda8 eca77cb4 000008c1 c058317c [ 62.673071] 7ca0: 000008c1 ed41d030 ed41ce00 ed41ce04 ed41d000 c02da044 ed41cf48 c0375870 [ 62.681230] 7cc0: ed9d3c04 ed9d3c00 ed52df80 bf000940 fffffff0 c03758f4 c03758c0 00000000 [ 62.689389] 7ce0: bf000564 c03614e0 ed9d3c04 bf000194 c0082f38 00000001 00000000 c0000100 [ 62.697548] 7d00: c0814488 c0814488 c086b1dc c05893a8 00000000 ed7e8320 00000000 c0128b88 [ 62.705707] 7d20: ed8a6b40 00000000 00000000 ed410500 ed8a6b40 c0594818 ed7e8320 00000000 [ 62.713867] 7d40: 00000000 c0129f20 00000000 c082c444 ed8a6b40 c012a684 00001000 00000000 [ 62.722026] 7d60: c0594818 c082c444 00000000 00000000 ed52df80 ed52df80 00000000 00000000 [ 62.730185] 7d80: 00000000 00000000 00000001 00000002 ed8e9b70 ed52df80 bf0006d0 00000000 [ 62.738345] 7da0: ed8e9b70 ed410500 ed618340 c036129c ed8c1c00 bf0006d0 c080b158 ed8c1c00 [ 62.746504] 7dc0: bf0006d0 c080b158 ed8c1c08 ed410500 c0082f38 ed618340 000008c1 c03640ac [ 62.754663] 7de0: 00000000 bf0006d0 c082c8dc c080b158 c080b158 c03642d4 00000000 bf003000 [ 62.762822] 7e00: 00000000 c0009784 00000000 00000001 00000000 c05849b0 00000002 ee7ab780 [ 62.770981] 7e20: 00000002 ed4105c0 0000c53e 000000d0 c0808600 eca77e5c 00000004 00000000 [ 62.779140] 7e40: bf000000 c0095680 c08075a0 ee001f00 ed4105c0 c00cadc0 ed52df80 bf000780 [ 62.787300] 7e60: ed4105c0 bf000780 00000001 bf0007c8 c0082f38 ed618340 000008c1 c0083e24 [ 62.795459] 7e80: 00000001 bf000780 00000001 eca77f58 00000001 bf000780 00000001 c00857f4 [ 62.803618] 7ea0: bf00078c 00007fff 00000000 c00835b4 eca77f58 00000000 c0082fac eca77f58 [ 62.811777] 7ec0: f05038c0 0003b008 bf000904 00000000 00000000 bf00078c 6e72656b 00006c65 [ 62.819936] 7ee0: 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 [ 62.828095] 7f00: 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 [ 62.836255] 7f20: 00000000 00000000 00000000 00000000 00000000 00000000 00000003 0003b008 [ 62.844414] 7f40: 0000017b c000f5c8 eca76000 00000000 0003b008 c0085df8 f04ef000 0001b8a9 [ 62.852573] 7f60: f0503258 f05030c2 f0509fe8 00000968 00000dc8 00000000 00000000 00000000 [ 62.860732] 7f80: 00000029 0000002a 00000011 00000000 0000000a 00000000 33f6eb00 0003b008 [ 62.868892] 7fa0: bef01cac c000f400 33f6eb00 0003b008 00000003 0003b008 00000000 00000003 [ 62.877051] 7fc0: 33f6eb00 0003b008 bef01cac 0000017b 00000000 0003b008 0000000b 0003b008 [ 62.885210] 7fe0: bef01ae0 bef01ad0 0001dc23 b6e8c162 800b0070 00000003 c0c0c0c0 c0c0c0c0 [ 62.893380] [<c01277c0>] (kernfs_find_ns) from [<c0824888>] (pm_qos_latency_tolerance_attr_group+0x0/0x10) [ 62.903005] Code: e28dd00c e8bd80f0 e92d41f0 e2923000 (e1d0e4b4) [ 62.909115] ---[ end trace 02fb4373ef095c7b ]--- Acked-by: Michal Nazarewicz <mina86@mina86.com> Signed-off-by: Krzysztof Opasiak <k.opasiak@samsung.com> Signed-off-by: Felipe Balbi <balbi@ti.com> Signed-off-by: Sasha Levin <sasha.levin@oracle.com>

[ Upstream commit c998c078 ] Currently the 'registered' member of the cpuidle_device struct is set to 1 during cpuidle_register_device. In this same function there are checks to see if the device is already registered to prevent duplicate calls to register the device, but this value is never set to 0 even on unregister of the device. Because of this, any attempt to call cpuidle_register_device after a call to cpuidle_unregister_device will fail which shouldn't be the case. To prevent this, set registered to 0 when the device is unregistered.

[ Upstream commit 13407376 ] The write handler allocates skbs and queues them into data->readq. Read side should read them, if there is any. If there is none, skbs should be dropped by hdev->flush. But this happens only if the device is HCI_UP, i.e. hdev->power_on work was triggered already. When it was not, skbs stay allocated in the queue when /dev/vhci is closed. So purge the queue in ->release. Program to reproduce: #include <err.h> #include <fcntl.h> #include <stdio.h> #include <unistd.h> #include <sys/stat.h> #include <sys/types.h> #include <sys/uio.h> int main() { char buf[] = { 0xff, 0 }; struct iovec iov = { .iov_base = buf, .iov_len = sizeof(buf), }; int fd; while (1) { fd = open("/dev/vhci", O_RDWR); if (fd < 0) err(1, "open"); usleep(50); if (writev(fd, &iov, 1) < 0) err(1, "writev"); usleep(50); close(fd); } return 0; } Result: kmemleak: 4609 new suspected memory leaks unreferenced object 0xffff88059f4d5440 (size 232): comm "vhci", pid 1084, jiffies 4294912542 (age 37569.296s) hex dump (first 32 bytes): 20 f0 23 87 05 88 ff ff 20 f0 23 87 05 88 ff ff .#..... .#..... 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace: ...

[ Upstream commit 373a32c8 ] Both vhci_get_user and vhci_release race with open_timeout work. They both contain cancel_delayed_work_sync, but do not test whether the work actually created hdev or not. Since the work can be in progress and _sync will wait for finishing it, we can have data->hdev allocated when cancel_delayed_work_sync returns. But the call sites do 'if (data->hdev)' *before* cancel_delayed_work_sync. As a result: * vhci_get_user allocates a second hdev and puts it into data->hdev. The former is leaked. * vhci_release does not release data->hdev properly as it thinks there is none. Fix both cases by moving the actual test *after* the call to cancel_delayed_work_sync. This can be hit by this program: #include <err.h> #include <fcntl.h> #include <stdio.h> #include <stdlib.h> #include <time.h> #include <unistd.h> #include <sys/stat.h> #include <sys/types.h> int main(int argc, char **argv) { int fd; srand(time(NULL)); while (1) { const int delta = (rand() % 200 - 100) * 100; fd = open("/dev/vhci", O_RDWR); if (fd < 0) err(1, "open"); usleep(1000000 + delta); close(fd); } return 0; } And the result is: BUG: KASAN: use-after-free in skb_queue_tail+0x13e/0x150 at addr ffff88006b0c1228 Read of size 8 by task kworker/u13:1/32068 ============================================================================= BUG kmalloc-192 (Tainted: G E ): kasan: bad access detected ----------------------------------------------------------------------------- Disabling lock debugging due to kernel taint INFO: Allocated in vhci_open+0x50/0x330 [hci_vhci] age=260 cpu=3 pid=32040 ... kmem_cache_alloc_trace+0x150/0x190 vhci_open+0x50/0x330 [hci_vhci] misc_open+0x35b/0x4e0 chrdev_open+0x23b/0x510 ...

[ Upstream commit c18d8f50 ] A number of new laptops have been delivered with only a single antenna. In principle, this is OK; however, a problem arises when the on-board EEPROM is programmed to use the other antenna connection. The option of opening the computer and moving the connector is not always possible as it will void the warranty in some cases. In addition, this solution breaks the Windows driver when the box dual boots Linux and Windows. A fix involving a new module parameter has been developed. This commit adds the new parameter and implements the changes needed for the driver.

[ Upstream commit 96f859d5 ] Because struct xfs_agfl is 36 bytes long and has a 64-bit integer inside it, gcc will quietly round the structure size up to the nearest 64 bits -- in this case, 40 bytes. This results in the XFS_AGFL_SIZE macro returning incorrect results for v5 filesystems on 64-bit machines (118 items instead of 119). As a result, a 32-bit xfs_repair will see garbage in AGFL item 119 and complain. Therefore, tell gcc not to pad the structure so that the AGFL size calculation is correct. cc: <stable@vger.kernel.org> # 3.10 - 4.4 Signed-off-by: Darrick J.

[ Upstream commit ad747e3b ] Commit 96f859d5 ("libxfs: pack the agfl header structure so XFS_AGFL_SIZE is correct") allowed the freelist to use the empty slot at the end of the freelist on 64 bit systems that was not being used due to sizeof() rounding up the structure size. This has caused versions of xfs_repair prior to 4.5.0 (which also has the fix) to report this as a corruption once the filesystem has been grown. Older kernels can also have problems (seen from a whacky container/vm management environment) mounting filesystems grown on a system with a newer kernel than the vm/container it is deployed on. To avoid this problem, change the initial free list indexes not to wrap across the end of the AGFL, hence avoiding the initialisation of agf_fllast to the last index in the AGFL. cc: <stable@vger.kernel.org> # 4.4-4.5 Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Carlos Maiolino <cmaiolino@redhat.com> Signed-off-by: Dave Chinner <david@fromorbit.com> Signed-off-by: Sasha Levin <sasha.levin@oracle.com>

[ Upstream commit d0a58e83 ] Today, a kernel which refuses to mount a filesystem read-write due to unknown ro-compat features can still transition to read-write via the remount path. The old kernel is most likely none the wiser, because it's unaware of the new feature, and isn't using it. However, writing to the filesystem may well corrupt metadata related to that new feature, and moving to a newer kernel which understand the feature will have problems. Right now the only ro-compat feature we have is the free inode btree, which showed up in v3.16. It would be good to push this back to all the active stable kernels, I think, so that if anyone is using newer mkfs (which enables the finobt feature) with older kernel releases, they'll be protected.

[ Upstream commit 5e3ca2b3 ] Commit 6261b06d ("regulator: Defer lookup of supply to regulator_get") moved the regulator supplies lookup logic from the regulators registration to the regulators get time. Unfortunately, that changed the behavior of the regulator core since now a parent supply with a child regulator marked as always-on, won't be enabled unless a client driver attempts to get the child regulator during boot. This patch tries to resolve the parent supply for the already registered regulators each time that a new regulator is registered. So the regulators that have child regulators marked as always on will be enabled regardless if a driver gets the child regulator or not. That was the behavior before the mentioned commit, since parent supplies were looked up at regulator registration time instead of during child get. Since regulator_resolve_supply() checks for rdev->supply, most of the times it will be a no-op. Errors aren't checked to keep the possible out of order dependencies which was the motivation for the mentioned commit. Also, the supply being available will be enforced on regulator get anyways in case the resolve fails on regulators registration.

[ Upstream commit ab92b232 ] Currently, the PT driver always sets the PMI bit one region (page) before the STOP region so that we can wake up the consumer before we run out of room in the buffer and have to disable the event. However, we also need an interrupt in the last output region, so that we actually get to disable the event (if no more room from new data is available at that point), otherwise hardware just quietly refuses to start, but the event is scheduled in and we end up losing trace data till the event gets removed. For a cpu-wide event it is even worse since there may not be any re-scheduling at all and no chance for the ring buffer code to notice that its buffer is filled up and the event needs to be disabled (so that the consumer can re-enable it when it finishes reading the data out). In other words, all the trace data will be lost after the buffer gets filled up. This patch makes PT also generate a PMI when the last output region is full.

[ Upstream commit c25a1e06 ] Commit 702e5bc6 ("ocfs2: use generic posix ACL infrastructure") refactored code to use posix_acl_create. The problem with this function is that it is not mindful of the cluster wide inode lock making it unsuitable for use with ocfs2 inode creation with ACLs. For example, when used in ocfs2_mknod, this function can cause deadlock as follows. The parent dir inode lock is taken when calling posix_acl_create -> get_acl -> ocfs2_iop_get_acl which takes the inode lock again. This can cause deadlock if there is a blocked remote lock request waiting for the lock to be downconverted. And same deadlock happened in ocfs2_reflink. This fix is to revert back using ocfs2_init_acl.

[ Upstream commit 5ee0fbd5 ] Commit 743b5f14 ("ocfs2: take inode lock in ocfs2_iop_set/get_acl()") introduced this issue. ocfs2_setattr called by chmod command holds cluster wide inode lock when calling posix_acl_chmod. This latter function in turn calls ocfs2_iop_get_acl and ocfs2_iop_set_acl. These two are also called directly from vfs layer for getfacl/setfacl commands and therefore acquire the cluster wide inode lock. If a remote conversion request comes after the first inode lock in ocfs2_setattr, OCFS2_LOCK_BLOCKED will be set. And this will cause the second call to inode lock from the ocfs2_iop_get_acl() to block indefinetly. The deleted version of ocfs2_acl_chmod() calls __posix_acl_chmod() which does not call back into the filesystem. Therefore, we restore ocfs2_acl_chmod(), modify it slightly for locking as needed, and use that instead.

The hotplug rework will solve this problem because | the callbacks become symetric, but for the existing mess, we need some | workaround in the workqueue code. The boot CPU handles housekeeping duty(unbound timers, workqueues, timekeeping, ...) on behalf of full dynticks CPUs. It must remain online when nohz full is enabled. There is a priority set to every notifier_blocks: workqueue_cpu_up > tick_nohz_cpu_down > workqueue_cpu_down So tick_nohz_cpu_down callback failed when down prepare cpu 0, and notifier_blocks behind tick_nohz_cpu_down will not be called any more, which leads to workers are actually not unbound. Then hotplug state machine will fallback to undo and online cpu 0 again. Workers will be rebound unconditionally even if they are not unbound and trigger the warning in this progress.

At this point the consumer still has to be woken up and the event has to be disabled, otherwise the event will just keep spinning between perf_aux_output_begin() and perf_aux_output_end() until its context gets unscheduled. Again, for cpu-wide events this means never, so once in this condition, they will be forever losing data. Fix this by disabling the event and waking up the consumer in case of a truncated AUX record.

Although the commit above removed the calls of snd_hda_codec_build_pcms() and *_build_controls() at the controller driver probe, the similar calls in the reconfig were still left forgotten.
