| * [PATCH 1/2] proc: fix inode number bogorithmeticAlexey Dobriyan2008-08-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Id which proc gets from IDR for inode number and id which proc removes from IDR do not match. E.g. 0x11a transforms into 0x8000011a. Which stayed unnoticed for a long time because, surprise, idr_remove() masks out that high bit before doing anything. All of this due to "| ~MAX_ID_MASK" in release_inode_number(). I still don't understand how it's supposed to work, because "| ~MASK" is not an inversion for "& MAX" operation. So, use just one nice, working addition. Make start offset unsigned int, while I'm at it. It's longness is not used anywhere.

I do not know from how many places the function is called from, but for example, SELinux Access Vector Cache tries to log untrusted filenames via call path: avc_audit() audit_log_untrustedstring() audit_log_n_untrustedstring() audit_string_contains_control() If audit_string_contains_control() detects control characters, then the string is hex-encoded. But the hex=0x7f dec=127, DEL-character, is not detected. I guess this could have at least some minor security implications, since a user can create a filename with 0x7f in it, causing logged filename to possibly look different when someone reads it on the terminal.

This framework is designed to provide a generic interface to voltage and current regulators within the Linux kernel. It's intended to provide voltage and current control to client or consumer drivers and also provide status information to user space applications through a sysfs interface. The intention is to allow systems to dynamically control regulator output in order to save power and prolong battery life. This applies to both voltage regulators (where voltage output is controllable) and current sinks (where current output is controllable). This framework safely compiles out if not selected so that client drivers can still be used in systems with no software controllable regulators.

This also compiles out if not in use so drivers can be reused in systems with no regulator based power control.

This is a configuration problem but we can certainly be more graceful. This patch just ignores -EINVAL when displaying LSM options and causes /proc/mounts display everything else it can. If policy isn't loaded the obviously there are no options, so we aren't really loosing any information here. This is safe as the only other return of EINVAL comes from security_sid_to_context_core() in the case of an invalid sid. Even if a FS was mounted with a now invalidated context that sid should have been remapped to unlabeled and so we won't hit the EINVAL and will work like we should.
