* fs: fix standard zero, full devicesSascha Hauer2012-07-042-5/+6
| | | | | | | | | | | | | | | | The standard devices are currently broken since they have the size ~0. As now files use loff_t as file size which is a signed type the read implementation gets confused and now returns -1. The current implementation also has the (somewhat theorical) problem that we do not have real streaming devices, so /dev/zero went out of zeroes after reading 4GB (or now LLONG_MAX). This patch introduces a new cdev flag DEVFS_IS_CHARACTER_DEV and a new file size flag FILE_SIZE_STREAM which makes it possible to create real stream devices instead.

| * resource: store 'end' instead of 'size' in struct resourceSascha Hauer2012-07-012-3/+3
| | | | | | | | | | | | | | | | | | | | Storing the size instead of the resource end in struct resource was a mistake. 'size' ranges from 0 to UINT[32|64]_MAX + 1 which obviously leads to problems. 'end' on the other hand will never exceed UINT[32|64]_MAX. Also this way we can express a iomem region covering the whole address space. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* | mtd: fix arguments to bad block ioctlsSascha Hauer2012-06-301-3/+3
|/ | | | | | | | | In the Kernel the mtd ioctls expect a pointer to the offset, whereas barebox interprets the pointer itself as an offset. Since we want to add 64bit support for file sizes a pointer may not be sufficient, so align with the kernel and convert it to a pointer to the offset.

* fs: limit flash erase and protect to the partiton boundaryJohannes Stezenbach2012-06-071-10/+8
| | | | | | | | | | | | | Passing a too large size or offset to erase could affect flash outside the partition boundary. Addresses for SPI flash wrap around, thus giving a count + offset going past the end of the flash would wrap around and erase flash at offset 0. Add the same check for protect.

| * lseek: return -1 instead of -errnoSascha Hauer2012-05-181-2/+2
| | | | | | | | | | | | | | | | | | | | The patch making errno a positive value has another bug: lseek was switched to return -errno instead of -1. This does not work since we can lseek we can address the whole 4G address space, have of which has a negative offset when interpreted as a signed integer. Let lseek return -1 on failure again instead. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* Add automount supportSascha Hauer2012-03-182-0/+122
| | | | | | | | | | | | | | This patch adds an automount command which makes it possible to execute a script when a certain directory is first accessed. It's the commands responsibility to make this directory available (bringing devices up and mounting it). This results in automount support which makes sure that from the shell every file can be accessed without having to care for device bringup. Bringing up devices may be expensive (USB, dhcp). The automount support makes it easy for the environment to bringup devices when they are actually needed. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* fs: drop struct mtab_entrySascha Hauer2012-03-171-45/+43
| | | | | | | | | | every struct fs_device_d contains a struct mtab_entry, so they have a 1:1 relationship. Instead of having to use container_of to get from a struct mtab_entry to a struct fs_device_d we can better embed the members of struct mtab_entry into struct fs_device_d directly.

This patch changes the name of this function to get_fs_device_and_root_path to better reflect what the function does and changes the return type to struct fs_device_d.
