* remove checks for xzalloc() returning NULLUwe Kleine-König2017-09-262-4/+0

* fs: Don't bother filesystems without link support with additional stat() callsSascha Hauer2017-09-061-0/+10
| | | | | | | | | | | | | In __canonicalize_path() we only call stat() to know if the path is a link or not. When the filesystem doesn't support links we already know that it's not a link, so we do not need to call stat(). This helps the tftp filesystem since the parent directories of a file to be opened won't be stat()ed anymore, something tftp does not support.

* fs: avoid pathes with '//' in __canonicalize_path()Sascha Hauer2017-09-061-2/+7
| | | | | | | | | In __canonicalize_path pathes beginning with '//' can occur. This is normally not a problem since normalize_path() will clean this up, but it means we cannot call get_fsdevice_by_path() on these pathes in this function, as needed in the next patch.

| * fs: Create automount entries for the default mount pathesSascha Hauer2017-05-102-0/+16
| | | | | | | | | | | | | | | | | | | | In barebox the default mount path for a cdev is /mnt/<cdevname> which can be mounted with "mount <cdevname>" without specifying a target path explicitly. Simplify this further by creating automount entries for the default mount pathes which makes a manual mount completely unnecessary. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* | fs: drop path_check_prereq()Sascha Hauer2017-05-111-65/+48
|/ | | | | | | | | | | | | | | | | path_check_prereq() has some bugs: - It's called with S_IFLNK, but this is effectively a no-op because this case is not implemented in the function - It uses lstat, but if stat or lstat should be used depends on the usecase: For opendir() stat() must be used, since we are not interested in the link, but in the target. For readlink() lstat() must be used since we are indeed interested in the link, not the target. It's easier and better understandable to open code the functionality where it's needed, so drop path_check_prereq() and do the right thing where called.

This currently matches on the `hsqs` start sequence of an image file. Additionally, the newly introduced filetype is registered as the type of the squashfs_driver which allows, for example, to mount squashfs without the need to specify a type parameter. This changes enable booting a squashfs with the simple `boot` command pointing to the location (device) that holds the squashfs. Note that booting with blspec is limited as the current squashfs driver is not capable of handling symbolic links.
