The default for llseek will change to no_llseek, so securityfs users need to add explicit .llseek assignments. Since we're dealing with regular files from a VFS perspective, use generic_file_llseek.

TOMOYO does not deal offset pointer. Thus seek operation makes no sense. Changing default seek operation from default_llseek() to no_llseek() might break some applications. Thus, explicitly set noop_llseek(). Signed-off-by: NTetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp> Signed-off-by: NJames Morris <jmorris@namei.org>

In commit bb952bb9 there was the accidental deletion of a statement from call_sbin_request_key() to render the process keyring ID to a text string so that it can be passed to /sbin/request-key. With gcc 4.6.0 this causes the following warning: CC security/keys/request_key.o security/keys/request_key.c: In function 'call_sbin_request_key': security/keys/request_key.c:102:15: warning: variable 'prkey' set but not used This patch reinstates that statement. Without this statement, /sbin/request-key will get some random rubbish from the stack as that parameter. Signed-off-by: NJustin P.

keyctl_describe_key() turns the key reference it gets into a usable key pointer and assigns that to a variable called 'key', which it then ignores in favour of recomputing the key pointer each time it needs it. Make it use the precomputed pointer instead. Without this patch, gcc 4.6 reports that the variable key is set but not used: building with gcc 4.6 I'm getting a warning message: CC security/keys/keyctl.o security/keys/keyctl.c: In function 'keyctl_describe_key': security/keys/keyctl.c:472:14: warning: variable 'key' set but not used Reported-by: NJustin P.

When userspace program reads policy from /sys/kernel/security/tomoyo/ interface, TOMOYO uses line buffered mode. A line has at least one word. Commit 006dacc "TOMOYO: Support longer pathname." changed a word's max length from 4000 bytes to max kmalloc()able bytes. By that commit, a line's max length changed from 8192 bytes to more than max kmalloc()able bytes. Max number of words in a line remains finite. This patch changes the way of buffering so that all words in a line are firstly directly copied to userspace buffer as much as possible and are secondly queued for next read request. Words queued are guaranteed to be valid until /sys/kernel/security/tomoyo/ interface is close()d.

Some programs behave differently depending on argv[0] passed to execve(). TOMOYO has "alias" keyword in order to allow administrators to define different domains if requested pathname passed to execve() is a symlink. But "alias" keyword is incomplete because this keyword assumes that requested pathname and argv[0] are identical. Thus, remove "alias" keyword (by this patch) and add syntax for checking argv[0] (by future patches).

At present, the socket related access controls use a mix of inode and socket labels; while there should be no practical difference (they _should_ always be the same), it makes the code more confusing. This patch attempts to convert all of the socket related access control points (with the exception of some of the inode/fd based controls) to use the socket's own label. In the process, I also converted the socket_has_perm() function to take a 'sock' argument instead of a 'socket' since that was adding a bit more overhead in some cases.

Make /proc/keys check to see if the calling process possesses each key before performing the security check.

Authorise a process to perform keyctl_set_timeout() on an uninstantiated key if that process has the authorisation key for it. This allows the instantiator to set the timeout on a key it is instantiating - provided it does it before instantiating the key. For instance, the test upcall script provided with the keyutils package could be modified to set the expiry to an hour hence before instantiating the key: [/usr/share/keyutils/request-key-debug.sh] if [ "$3" != "neg" ] then + keyctl timeout $1 3600 keyctl instantiate $1 "Debug $3" $4 || exit 1 else Signed-off-by: NDavid Howells <dhowells@redhat.com> Signed-off-by: NJames Morris <jmorris@namei.org>

This patch allows users to change access control mode for per-operation basis. This feature comes from non LSM version of TOMOYO which is designed for permitting users to use SELinux and TOMOYO at the same time. SELinux does not care filename in a directory whereas TOMOYO does. Change of filename can change how the file is used. For example, renaming index.txt to .htaccess will change how the file is used. Thus, letting SELinux to enforce read()/write()/mmap() etc. restriction and letting TOMOYO to enforce rename() restriction is an example usage of this feature. What is unfortunate for me is that currently LSM does not allow users to use SELinux and LSM version of TOMOYO at the same time...
