CONFIG_MODVERSIONS has been broken for pretty much the whole 4.9 series, and quite frankly, nobody has cared very deeply. We absolutely know how to fix it, and it's not _complicated_, but it's not exactly pretty either. This oneliner fixes it without the ugliness, and allows for further future cleanups.

One of them reverts a recent ACPI commit that attempted to improve reboot/power-off on some systems, but introduced problems elsewhere, and the other one fixes kernel builds with the new WDAT watchdog driver enabled in some configurations.

The kernel WARNs and then crashes today if wm8994_device_init() fails after calling devm_regulator_bulk_get(). That happens because there are multiple devices involved here and the order in which managed resources are freed isn't correct. The regulators are added as children of wm8994->dev. Whereas, devm_regulator_bulk_get() receives wm8994->dev as the device, though it gets the same regulators which were added as children of wm8994->dev earlier. During failures, the children are removed first and the core eventually calls regulator_unregister() for them. As regulator_put() was never done for them (opposite of devm_regulator_bulk_get()), the kernel WARNs at WARN_ON(rdev->open_count); And eventually it crashes from debugfs_remove_recursive(). --------x------------------x---------------- wm8994 3-001a: Device is not a WM8994, ID is 0 ------------[ cut here ]------------ WARNING: CPU: 0 PID: 1 at /mnt/ssd/all/work/repos/devel/linux/drivers/regulator/core.c:4072 regulator_unregister+0xc8/0xd0 Modules linked in: CPU: 0 PID: 1 Comm: swapper/0 Not tainted 4.8.0-rc6-00154-g54fe84cbd50b #41 Hardware name: SAMSUNG EXYNOS (Flattened Device Tree) [<c010e24c>] (unwind_backtrace) from [<c010af38>] (show_stack+0x10/0x14) [<c010af38>] (show_stack) from [<c032a1c4>] (dump_stack+0x88/0x9c) [<c032a1c4>] (dump_stack) from [<c011a98c>] (__warn+0xe8/0x100) [<c011a98c>] (__warn) from [<c011aa54>] (warn_slowpath_null+0x20/0x28) [<c011aa54>] (warn_slowpath_null) from [<c0384a0c>] (regulator_unregister+0xc8/0xd0) [<c0384a0c>] (regulator_unregister) from [<c0406434>] (release_nodes+0x16c/0x1dc) [<c0406434>] (release_nodes) from [<c04039c4>] (__device_release_driver+0x8c/0x110) [<c04039c4>] (__device_release_driver) from [<c0403a64>] (device_release_driver+0x1c/0x28) [<c0403a64>] (device_release_driver) from [<c0402b24>] (bus_remove_device+0xd8/0x104) [<c0402b24>] (bus_remove_device) from [<c03ffcd8>] (device_del+0x10c/0x218) [<c03ffcd8>] (device_del) from [<c0404e4c>] (platform_device_del+0x1c/0x88) [<c0404e4c>] (platform_device_del) from [<c0404ec4>] (platform_device_unregister+0xc/0x20) [<c0404ec4>] (platform_device_unregister) from [<c0428bc0>] (mfd_remove_devices_fn+0x5c/0x64) [<c0428bc0>] (mfd_remove_devices_fn) from [<c03ff9d8>] (device_for_each_child_reverse+0x4c/0x78) [<c03ff9d8>] (device_for_each_child_reverse) from [<c04288c4>] (mfd_remove_devices+0x20/0x30) [<c04288c4>] (mfd_remove_devices) from [<c042758c>] (wm8994_device_init+0x2ac/0x7f0) [<c042758c>] (wm8994_device_init) from [<c04f14a8>] (i2c_device_probe+0x178/0x1fc) [<c04f14a8>] (i2c_device_probe) from [<c04036fc>] (driver_probe_device+0x214/0x2c0) [<c04036fc>] (driver_probe_device) from [<c0403854>] (__driver_attach+0xac/0xb0) [<c0403854>] (__driver_attach) from [<c0401a74>] (bus_for_each_dev+0x68/0x9c) [<c0401a74>] (bus_for_each_dev) from [<c0402cf0>] (bus_add_driver+0x1a0/0x218) [<c0402cf0>] (bus_add_driver) from [<c040406c>] (driver_register+0x78/0xf8) [<c040406c>] (driver_register) from [<c04f20a0>] (i2c_register_driver+0x34/0x84) [<c04f20a0>] (i2c_register_driver) from [<c01017d0>] (do_one_initcall+0x40/0x170) [<c01017d0>] (do_one_initcall) from [<c0a00dbc>] (kernel_init_freeable+0x15c/0x1fc) [<c0a00dbc>] (kernel_init_freeable) from [<c06e07b0>] (kernel_init+0x8/0x114) [<c06e07b0>] (kernel_init) from [<c0107978>] (ret_from_fork+0x14/0x3c) ---[ end trace 0919d3d0bc998260 ]--- [snip..] Unable to handle kernel NULL pointer dereference at virtual address 00000078 pgd = c0004000 [00000078] *pgd=00000000 Internal error: Oops: 5 [#1] PREEMPT SMP ARM Modules linked in: CPU: 0 PID: 1 Comm: swapper/0 Tainted: G W 4.8.0-rc6-00154-g54fe84cbd50b #41 Hardware name: SAMSUNG EXYNOS (Flattened Device Tree) task: ee874000 task.stack: ee878000 PC is at down_write+0x14/0x54 LR is at debugfs_remove_recursive+0x30/0x150 [snip..] [<c06e489c>] (down_write) from [<c02e9954>] (debugfs_remove_recursive+0x30/0x150) [<c02e9954>] (debugfs_remove_recursive) from [<c0382b78>] (_regulator_put+0x24/0xac) [<c0382b78>] (_regulator_put) from [<c0382c1c>] (regulator_put+0x1c/0x2c) [<c0382c1c>] (regulator_put) from [<c0406434>] (release_nodes+0x16c/0x1dc) [<c0406434>] (release_nodes) from [<c04035d4>] (driver_probe_device+0xec/0x2c0) [<c04035d4>] (driver_probe_device) from [<c0403854>] (__driver_attach+0xac/0xb0) [<c0403854>] (__driver_attach) from [<c0401a74>] (bus_for_each_dev+0x68/0x9c) [<c0401a74>] (bus_for_each_dev) from [<c0402cf0>] (bus_add_driver+0x1a0/0x218) [<c0402cf0>] (bus_add_driver) from [<c040406c>] (driver_register+0x78/0xf8) [<c040406c>] (driver_register) from [<c04f20a0>] (i2c_register_driver+0x34/0x84) [<c04f20a0>] (i2c_register_driver) from [<c01017d0>] (do_one_initcall+0x40/0x170) [<c01017d0>] (do_one_initcall) from [<c0a00dbc>] (kernel_init_freeable+0x15c/0x1fc) [<c0a00dbc>] (kernel_init_freeable) from [<c06e07b0>] (kernel_init+0x8/0x114) [<c06e07b0>] (kernel_init) from [<c0107978>] (ret_from_fork+0x14/0x3c) Code: e1a04000 f590f000 e3a03001 e34f3fff (e1902f9f) ---[ end trace 0919d3d0bc998262 ]--- --------x------------------x---------------- Fix the kernel warnings and crashes by using regulator_bulk_get() instead of devm_regulator_bulk_get() and explicitly freeing the supplies in exit paths.

The commit 8dfbcc43 ("[media] xc2028: avoid use after free") tried to address the reported use-after-free by clearing the reference. However, it's clearing the wrong pointer; it sets NULL to priv->ctrl.fname, but it's anyway overwritten by the next line memcpy(&priv->ctrl, p, sizeof(priv->ctrl)). OTOH, the actual code accessing the freed string is the strcmp() call with priv->fname: if (!firmware_name[0] && p->fname && priv->fname && strcmp(p->fname, priv->fname)) free_firmware(priv); where priv->fname points to the previous file name, and this was already freed by kfree(). For fixing the bug properly, this patch does the following: - Keep the copy of firmware file name in only priv->fname, priv->ctrl.fname isn't changed; - The allocation is done only when the firmware gets loaded; - The kfree() is called in free_firmware() commonly Fixes: commit 8dfbcc43 ('[media] xc2028: avoid use after free') Cc: <stable@vger.kernel.org> Signed-off-by: NTakashi Iwai <tiwai@suse.de> Signed-off-by: NMauro Carvalho Chehab <mchehab@s-opensource.com>

Pull arch/tile bugfix from Chris Metcalf: "This fixes a bug that causes reboots after 208 days of uptime :-)" * 'stable' of git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile: tile: avoid using clocksource_cyc2ns with absolute cycle count
-
由 Chris Metcalf 提交于
For large values of "mult" and long uptimes, the intermediate result of "cycles * mult" can overflow 64 bits. For example, the tile platform calls clocksource_cyc2ns with a 1.2 GHz clock; we have mult = 853, and after 208.5 days, we overflow 64 bits. Since clocksource_cyc2ns() is intended to be used for relative cycle counts, not absolute cycle counts, performance is more importance than accepting a wider range of cycle values. So, just use mult_frac() directly in tile's sched_clock(). Commit 4cecf6d4 ("sched, x86: Avoid unnecessary overflow in sched_clock") by Salman Qazi results in essentially the same generated code for x86 as this change does for tile. In fact, a follow-on change by Salman introduced mult_frac() and switched to using it, so the C code was largely identical at that point too. Peter Zijlstra then added mul_u64_u32_shr() and switched x86 to use it. This is, in principle, better; by optimizing the 64x64->64 multiplies to be 32x32->64 multiplies we can potentially save some time. However, the compiler piplines the 64x64->64 multiplies pretty well, and the conditional branch in the generic mul_u64_u32_shr() causes some bubbles in execution, with the result that it's pretty much a wash. If tilegx provided its own implementation of mul_u64_u32_shr() without the conditional branch, we could potentially save 3 cycles, but that seems like small gain for a fair amount of additional build scaffolding; no other platform currently provides a mul_u64_u32_shr() override, and tile doesn't currently have an <asm/div64.h> header to put the override in. Additionally, gcc currently has an optimization bug that prevents it from recognizing the opportunity to use a 32x32->64 multiply, and so the result would be no better than the existing mult_frac() until such time as the compiler is fixed. For now, just using mult_frac() seems like the right answer. Cc: stable@kernel.org [v3.4+] Signed-off-by: NChris Metcalf <cmetcalf@mellanox.com>

When user tried to read some fields like hysteresis from IIO sysfs on some systems, it fails. The reason is that this field is a byte field and caller of sensor_hub_get_feature() passes a buffer of 4 bytes. Here the function sensor_hub_get_feature() copies the single byte from the report to the caller buffer and returns "1" as the number of bytes copied. So caller can use the return value. But this is done by multiple callers, so if we just change the sensor_hub_get_feature so that caller buffer is initialized with 0s then we don't to change all functions.

Kernel v4.9 strictly enforces DMA capable buffers, so we need to remove buffers allocated on the stack. Use a spinlock to prevent concurrent accesses to the buffer. Signed-off-by: NBenjamin Tissoires <benjamin.tissoires@redhat.com> Signed-off-by: NJiri Kosina <jkosina@suse.cz>

Pull crypto fixes from Herbert Xu: "The last push broke algif_hash for all shash implementations, so this is a follow-up to fix that.

Pull thermal management fix from Zhang Rui: "We only have one urgent fix this time. Commit 3105f234 ("thermal/powerclamp: correct cpu support check"), which is shipped in 4.9-rc3, fixed a problem introduced by commit b721ca0d ("thermal/powerclamp: remove cpu whitelist"). But unfortunately, it broke intel_powerclamp driver module auto- loading at the same time. Thus we need this change to add back module auto-loading for 4.9" * 'for-rc' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux: thermal/powerclamp: add back module device table

Pull SCSI fixes from James Bottomley: "Two small fixes. One prevents timeouts on mpt3sas when trying to use the secure erase protocol which causes the erase protocol to be aborted. The second is a regression in a prior fix which causes all commands to abort during PCI extended error recovery, which is incorrect because PCI EEH is independent from what's happening on the FC transport" * tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: scsi: qla2xxx: do not abort all commands in the adapter during EEH recovery scsi: mpt3sas: Fix secure erase premature termination

A correct bugfix introduced a harmless warning that shows up with gcc-7: fs/nfs/callback.c: In function 'nfs_callback_up': fs/nfs/callback.c:214:14: error: array subscript is outside array bounds [-Werror=array-bounds] What happens here is that the 'minorversion == 0' check tells the compiler that we assume minorversion can be something other than 0, but when CONFIG_NFS_V4_1 is disabled that would be invalid and result in an out-of-bounds access. The added check for IS_ENABLED(CONFIG_NFS_V4_1) tells gcc that this really can't happen, which makes the code slightly smaller and also avoids the warning. The bugfix that introduced the warning is marked for stable backports, we want this one backported to the same releases.
