* fs: add basic sanity check before accessing the files arrayBaruch Siach2010-07-281-0/+34
| | | | | | | | | This patch adds some basic file descriptor sanity checks to the file access routines. Check whether the given file descriptor is in the files array range, and whether the file entry is valid.

* cramfs: probe(): fix cdev lookupPeter Korsgaard2009-12-161-1/+1
| | | | | | | | Strip /dev/ part of backing store before passing cdev_by_name, as cramfs_probe() will otherwise always fail. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* devfs: add open counterSascha Hauer2009-09-111-7/+29
| | | | | | | Add an open counter for device files so that we cannot accidently remove an opened device. This happened with bb devices. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* fs: write: fix writing on devicesSascha Hauer2009-07-301-3/+9
| | | | | | | | We can't truncate device files. Make sure that if we want to write beyond the device that the bytes that still fit into the device get written. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* [general] Fixed crash in fs.h, when called with fsdrv.create == NULLCarsten Schlote2008-02-191-2/+5
| | | | | | | | | | When a nor0 devices has no partitions assigned, then a call to open() to create a file will jump with a NULL fct ptr. Much more cheching code is missing and pointers to function are jumped without any NULL ptr check. This must be fixed as well later. Signed-off-by: Carsten Schlote <c.schlote@konzeptpark.de>
