USB: fix pm counter leak in usblp

2008-02-21T23:38:48Z

if you fail in open() you must decrement the pm counter again. Signed-off-by: Oliver Neukum Cc: stable Signed-off-by: Pete Zaitcev

Add missing newlines to some uses of dev_ messages

usblp: Fix a double kfree

2007-10-12T21:55:15Z

If submit fails, slab hits a BUG() because of a double kfree. The today's lesson is, you cannot just slap USB_FREE_BUFFER on code without adjusting the error paths. The patch is made bigger by opportunistic refactoring. Signed-Off-By: Pete Zaitcev Signed-off-by: Greg Kroah-Hartman

usblp: Cosmetics

2007-10-12T21:55:14Z

This is a small bunch of cosmetic fixes: - Timeout is not a write timeout anymore, rename - Condition in poll was confusingly backwards, invert and simplify - The comment log gave a wrong impression of version 0.13, terminate it. Signed-off-by: Pete Zaitcev Signed-off-by: Greg Kroah-Hartman

usblp: mutex in usblp_check_status

2007-10-12T21:55:14Z

Add a mutex to protect the ->statusbuf. Not really an issue, because CUPS is single-threaded when it talks to the printer, but I feel safer this way. This should be deadlock-free, but I kept this as a separate patch in case someone ends running a git bisect. Signed-off-by: Pete Zaitcev Signed-off-by: Greg Kroah-Hartman

usblp: Make use of URB_FREE_BUFFER

2007-10-12T21:54:58Z

Employ the new API URB_FREE_BUFFER that we've got. There was talk of a combined constructor for this case, but apparently it's not happening, so just set the flag explicitly for now. Signed-off-by: Pete Zaitcev Signed-off-by: Greg Kroah-Hartman

usblp: Implement the ENOSPC convention

2007-10-12T21:54:58Z

This patch implements a mode when a printer returns ENOSPC when it runs out of paper. The default remains the same as before. An application which wishes to use this function has to enable it explicitly with an ioctl LPABORT. This is done on a request by our (Fedora) CUPS guy, Tim Waugh. The API is similar enough to the lp0's one that CUPS works with both (but see below), but it's has some differences. Most importantly, the abort mode is persistent in case of lp0: once tunelp was run your cat fill blow up until you reboot or run tunelp again. For usblp, I made it so the abort mode is only in effect as long as device is open. This way you can mix and match CUPS and cat(1) freely and nothing bad happens even if you run out of paper. It is also safer in the face of any unexpected crashes. It has to be noted that mixing LPABORT and O_NONBLOCK is not advised. It probably does not do what you want: instead of returning -ENOSPC it will always return -EAGAIN (because it would otherwise block while waiting for the paper). Applications which use O_NONBLOCK should continue to use LPGETSTATUS like before. Finally, CUPS actually requires patching to take full advantage of this. It has several components; those which invoke LPABORT work, but some of them need the ioctl added. This is completely compatible, you can mix old CUPS and new kernels or vice versa.
