[PATCH] clk: fix leak on devm_clk_bulk_get_all() unwind

by Brian Norris

clk_bulk_get_all() allocates an array of struct clk_bulk data for us (unlike clk_bulk_get()), so we need to free it. Let's use the clk_bulk_put_all() helper. kmemleak complains, on an RK3399 Gru/Kevin system: unreferenced object 0xffffff80045def00 (size 128): comm "swapper/0", pid 1, jiffies 4294667682 (age 86.394s) hex dump (first 32 bytes): 44 32 60 fe fe ff ff ff 00 00 00 00 00 00 00 00 D2`............. 48 32 60 fe fe ff ff ff 00 00 00 00 00 00 00 00 H2`............. backtrace: [<00000000742860d6>] __kmalloc+0x22c/0x39c [<00000000b0493f2c>] clk_bulk_get_all+0x64/0x188 [<00000000325f5900>] devm_clk_bulk_get_all+0x58/0xa8 [<00000000175b9bc5>] dwc3_probe+0x8ac/0xb5c [<000000009169e2f9>] platform_drv_probe+0x9c/0xbc [<000000005c51e2ee>] really_probe+0x13c/0x378 [<00000000c47b1f24>] driver_probe_device+0x84/0xc0 [<00000000f870fcfb>] __device_attach_driver+0x94/0xb0 [<000000004d1b92ae>] bus_for_each_drv+0x8c/0xd8 [<00000000481d60c3>] __device_attach+0xc4/0x150 [<00000000a163bd36>] device_initial_probe+0x1c/0x28 [<00000000accb6bad>] bus_probe_device+0x3c/0x9c [<000000001a199f89>] device_add+0x218/0x3cc [<000000001bd84952>] of_device_add+0x40/0x50 [<000000009c658c29>] of_platform_device_create_pdata+0xac/0x100 [<0000000021c69ba4>] of_platform_bus_create+0x190/0x224 Fixes: f08c2e2865f6 ("clk: add managed version of clk_bulk_get_all") Cc: Dong Aisheng <aisheng.dong(a)nxp.com> Cc: stable(a)vger.kernel.org Signed-off-by: Brian Norris <briannorris(a)chromium.org> --- Never mind that kmemleak appears broken on 5.14-rc3+... but I caught the leak on an earlier kernel. drivers/clk/clk-devres.c | 9 ++++++++- 1 file changed, 8 insertions(+), 1 deletion(-) diff --git a/drivers/clk/clk-devres.c b/drivers/clk/clk-devres.c index be160764911b..f9d5b7334341 100644 --- a/drivers/clk/clk-devres.c +++ b/drivers/clk/clk-devres.c @@ -92,13 +92,20 @@ int __must_check devm_clk_bulk_get_optional(struct device *dev, int num_clks, } EXPORT_SYMBOL_GPL(devm_clk_bulk_get_optional); +static void devm_clk_bulk_release_all(struct device *dev, void *res) +{ + struct clk_bulk_devres *devres = res; + + clk_bulk_put_all(devres->num_clks, devres->clks); +} + int __must_check devm_clk_bulk_get_all(struct device *dev, struct clk_bulk_data **clks) { struct clk_bulk_devres *devres; int ret; - devres = devres_alloc(devm_clk_bulk_release, + devres = devres_alloc(devm_clk_bulk_release_all, sizeof(*devres), GFP_KERNEL); if (!devres) return -ENOMEM; -- 2.32.0.554.ge1b32706d8-goog

FAILED: patch "[PATCH] blk-iocost: fix operation ordering in iocg_wake_fn()" failed to apply to 5.4-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 5.4-stable tree.

The operation order was wrong and the regular list_del_init() was used. The result is that if a waiter wakes up racing the waker, it can free pop the wq_entry off stack before the waker is still looking at it, which can lead to a backtrace like the following.
