[PATCH 1/3] drm: Restore driver.preclose() for all to use

by Chris Wilson

An unfortunate sequence of events, but it turns out there is a valid usecase for being able to free/decouple the driver objects before they are freed by the DRM core. In particular, if we have a pointer into a drm core object from inside a driver object, that pointer needs to be nerfed *before* it is freed so that concurrent access (e.g. debugfs) does not following the dangling pointer. The legacy marker was adding in the code movement from drp_fops.c to drm_file.c References: 9acdac68bcdc ("drm: rename drm_fops.c to drm_file.c") Signed-off-by: Chris Wilson <chris(a)chris-wilson.co.uk> Cc: Daniel Vetter <daniel.vetter(a)intel.com> Cc: Gustavo Padovan <gustavo.padovan(a)collabora.com> Cc: CQ Tang <cq.tang(a)intel.com> Cc: <stable(a)vger.kernel.org> # v4.12+ --- drivers/gpu/drm/drm_file.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/drivers/gpu/drm/drm_file.c b/drivers/gpu/drm/drm_file.c index 0ac4566ae3f4..7b4258d6f7cc 100644 --- a/drivers/gpu/drm/drm_file.c +++ b/drivers/gpu/drm/drm_file.c @@ -258,8 +258,7 @@ void drm_file_free(struct drm_file *file) (long)old_encode_dev(file->minor->kdev->devt), atomic_read(&dev->open_count)); - if (drm_core_check_feature(dev, DRIVER_LEGACY) && - dev->driver->preclose) + if (dev->driver->preclose) dev->driver->preclose(dev, file); if (drm_core_check_feature(dev, DRIVER_LEGACY)) -- 2.20.1

[PATCH v2 1/2] media: uvcvideo: Fix uvc_ctrl_fixup_xu_info() not having any effect

by Hans de Goede

uvc_ctrl_add_info() calls uvc_ctrl_get_flags() which will override the fixed-up flags set by uvc_ctrl_fixup_xu_info(). uvc_ctrl_init_xu_ctrl() already calls uvc_ctrl_get_flags() before calling uvc_ctrl_add_info(), so the uvc_ctrl_get_flags() call in uvc_ctrl_add_info() is not necessary for xu ctrls. This commit moves the uvc_ctrl_get_flags() call for normal controls from uvc_ctrl_add_info() to uvc_ctrl_init_ctrl(), so that we no longer call uvc_ctrl_get_flags() twice for xu controls and so that we no longer override the fixed-up flags set by uvc_ctrl_fixup_xu_info(). This fixes the xu motor controls not working properly on a Logitech 046d:08cc, and presumably also on the other Logitech models which have a quirk for this in the uvc_ctrl_fixup_xu_info() function.

[PATCH] iscsi-target: fix hang in iscsit_access_np() when getting tpg->np_login_sem

by Hou Pu

The iscsi target login thread might stuck in following stack: cat /proc/`pidof iscsi_np`/stack [<0>] down_interruptible+0x42/0x50 [<0>] iscsit_access_np+0xe3/0x167 [<0>] iscsi_target_locate_portal+0x695/0x8ac [<0>] __iscsi_target_login_thread+0x855/0xb82 [<0>] iscsi_target_login_thread+0x2f/0x5a [<0>] kthread+0xfa/0x130 [<0>] ret_from_fork+0x1f/0x30 This could be reproduced by following steps: 1. Initiator A try to login iqn1-tpg1 on port 3260. After finishing PDU exchange in the login thread and before the negotiation is finished, at this time the network link is down. In a production environment, this could happen. I could emulated it by bring the network card down in the initiator node by ifconfig eth0 down. (Now A could never finish this login. And tpg->np_login_sem is hold by it). 2. Initiator B try to login iqn2-tpg1 on port 3260. After finishing PDU exchange in the login thread. The target expect to process remaining login PDUs in workqueue context. 3. Initiator A' try to re-login to iqn1-tpg1 on port 3260 from a new socket. It will wait for tpg->np_login_sem with np->np_login_timer loaded to wait for at most 15 second. (Because the lock is held by A. A never gets a change to release tpg->np_login_sem. so A' should finally get timeout). 4. Before A' got timeout. Initiator B gets negotiation failed and calls iscsi_target_login_drop()->iscsi_target_login_sess_out(). The np->np_login_timer is canceled. And initiator A' will hang there forever. Because A' is now in the login thread. All other login requests could not be serviced. Fix this by moving iscsi_stop_login_thread_timer() out of iscsi_target_login_sess_out(). Also remove iscsi_np parameter from iscsi_target_login_sess_out().

[PATCH 01/11] evm: Execute evm_inode_init_security() only when the HMAC key is loaded

by Roberto Sassu

evm_inode_init_security() requires the HMAC key to calculate the HMAC on initial xattrs provided by LSMs. Unfortunately, with the evm_key_loaded() check, the function continues even if the HMAC key is not loaded (evm_key_loaded() returns true also if EVM has been initialized only with a public key). If the HMAC key is not loaded, evm_inode_init_security() returns an error later when it calls evm_init_hmac(). Thus, this patch replaces the evm_key_loaded() check with a check of the EVM_INIT_HMAC flag in evm_initialized, so that evm_inode_init_security() returns 0 instead of an error.

I hope the "Fixes" tag will work, but yeah, my bad, cc:stable is definitely a good idea here. Added stable@ to cc. Thanks!
