* lib: include sys/stat.h for struct statRuediger Meier2016-03-071-0/+1
| | | | | | | Compiler warning: 'struct stat' will not be visible outside of this function [-Wvisibility] Signed-off-by: Ruediger Meier <ruediger.meier@ga-group.nl>
* lib/blkdev: add open_blkdev_or_file() functionSami Kerola2015-11-221-0/+3
| | | | | | | | | Purpose of this function is to open a path that is potentially pointing to a block device or file without races. The function also proper open(3) flags are used to check the device is not busy, and finally warning is been printed if a block device happens to be misaligned.

* mount: retry on ENOMEDIUMMatthias Koenig2008-07-301-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to a change in kernel behaviour when opening CDROM devices, we need to retry the open/mount call when ENOMEDIUM is returned. Explanation from Tejun Heo: Okay, the difference is from the addition of cdrom_get_media_event() call to both sr_drive_status() and ide_cdrom_drive_status(). Previously, the cdrom driver can't differentiate between tray closed w/ no media and tray open and always returned tray open, which triggers close and retry in the open logic which probably have delayed things enough to get the media recognized. Now the cdrom driver can discern between tray closed w/o media and device not ready for other reasons and returns -ENOMEDIUM on the former. This is all good and dandy but the problem seems that some drives report no media right after the tray is closed but it hasn't properly detected the media yet. It seems the only way to work around the problem is via sensible retries (e.g. try three times 5 secs apart) and I don't think we can add that type of retry logic into cdrom open path. Please note that the previous logic wasn't water proof. Some drives can take longer to recognize the media is there and could have failed the in-kernel retry too. Also, reading the media can take quite some time and during that period the drive reports media present but device not ready. The driver will retry the command (e.g. READ TOC for open) five times but all of them can fail w/ EMEDIUMTYPE.
