USB: Push BKL on open down into the drivers

2010-03-02T22:54:23+00:00

Straightforward push into the drivers to allow auditing individual drivers separately Signed-off-by: Oliver Neukum Acked-by: Mauro Carvalho Chehab Cc: Jiri Kosina Signed-off-by: Greg Kroah-Hartman

USB misc: make USB device id constant

2010-03-02T22:54:17+00:00

The id_table field of the struct usb_device_id is constant in so it is worth to make the initialization data also constant. The semantic match that finds this kind of pattern is as follows: (http://coccinelle.lip6.fr/) // @r@ disable decl_init,const_decl_init; identifier I1, I2, x; @@ struct I1 { ... const struct I2 *x; ... }; @s@ identifier r.I1, y; identifier r.x, E; @@ struct I1 y = { .x = E, }; @c@ identifier r.I2; identifier s.E; @@ const struct I2 E[] = ... ; @depends on !c@ identifier r.I2; identifier s.E; @@ + const struct I2 E[] = ...; // Signed-off-by: Németh Márton Cc: Julia Lawall Cc: cocci@diku.dk Signed-off-by: Greg Kroah-Hartman

USB: remove info() macro from usb/misc drivers

2008-10-17T21:41:09+00:00

USB should not be having it's own printk macros, so remove info() and use the system-wide standard of dev_info() wherever possible. Signed-off-by: Greg Kroah-Hartman

USB: fix locking in idmouse

2007-10-25T19:18:44+00:00

Pete caused me to lock at buggy drivers in this respect. The idmouse has a race between open and disconnect. This patch - solves the open/disconnect race - switches locking to mutexes Signed-off-by: Oliver Neukum Signed-off-by: Greg Kroah-Hartman

USB: prevent char device open/deregister race

2007-07-12T23:29:48+00:00

This patch (as908) adds central protection in usbcore for the prototypical race between opening and unregistering a char device. The spinlock used to protect the minor-numbers array is replaced with an rwsem, which can remain locked across a call to a driver's open() method. This guarantees that open() and deregister() will be mutually exclusive. The private locks currently used in several individual drivers for this purpose are no longer necessary, and the patch removes them. The following USB drivers are affected: usblcd, idmouse, auerswald, legousbtower, sisusbvga/sisusb, ldusb, adutux, iowarrior, and usb-skeleton. As a side effect of this change, usb_deregister_dev() must not be called while holding a lock that is acquired by open(). Unfortunately a number of drivers do this, but luckily the solution is simple: call usb_deregister_dev() before acquiring the lock. In addition to these changes (and their consequent code simplifications), the patch fixes a use-after-free bug in adutux and a race between open() and release() in iowarrior.

header cleaning: don't include smp_lock.h when not used

Remove includes of where it is not used/needed. Suggested by Al Viro. Builds cleanly on x86_64, i386, alpha, ia64, powerpc, sparc, sparc64, and arm (all 59 defconfigs). Signed-off-by: Randy Dunlap Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
