2013-03-19Fix NULL pointer dereference in smack_inode_unlink() and smack_inode_rmdir()Igor Zhbanov
This patch fixes kernel Oops because of wrong common_audit_data type in smack_inode_unlink() and smack_inode_rmdir(). When SMACK security module is enabled and SMACK logging is on (/smack/logging is not zero) and you try to delete the file which 1) you cannot delete due to SMACK rules and logging of failures is on or 2) you can delete and logging of success is on, you will see following: Unable to handle kernel NULL pointer dereference at virtual address 000002d7 [<...>] (strlen+0x0/0x28) [<...>] (audit_log_untrustedstring+0x14/0x28) [<...>] (common_lsm_audit+0x108/0x6ac) [<...>] (smack_log+0xc4/0xe4) [<...>] (smk_curacc+0x80/0x10c) [<...>] (smack_inode_unlink+0x74/0x80) [<...>] (security_inode_unlink+0x2c/0x30) [<...>] (vfs_unlink+0x7c/0x100) [<...>] (do_unlinkat+0x144/0x16c) The function smack_inode_unlink() (and smack_inode_rmdir()) need to log two structures of different types. First of all it does: smk_ad_init(&ad, __func__, LSM_AUDIT_DATA_DENTRY); smk_ad_setfield_u_fs_path_dentry(&ad, dentry); This will set common audit data type to LSM_AUDIT_DATA_DENTRY and store dentry for auditing (by function smk_curacc(), which in turn calls dump_common_audit_data(), which is actually uses provided data and logs it). /* * You need write access to the thing you're unlinking */ rc = smk_curacc(smk_of_inode(ip), MAY_WRITE, &ad); if (rc == 0) { /* * You also need write access to the containing directory */ Then this function wants to log anoter data: smk_ad_setfield_u_fs_path_dentry(&ad, NULL); smk_ad_setfield_u_fs_inode(&ad, dir); The function sets inode field, but don't change common_audit_data type. rc = smk_curacc(smk_of_inode(dir), MAY_WRITE, &ad); } So the dump_common_audit() function incorrectly interprets inode structure as dentry, and Oops will happen. This patch reinitializes common_audit_data structures with correct type. Also I removed unneeded smk_ad_setfield_u_fs_path_dentry(&ad, NULL); initialization, because both dentry and inode pointers are stored in the same union.

2012-07-13Smack: don't show empty rules when /smack/load or /smack/load2 is readRafal Krypa
This patch removes empty rules (i.e. with access set to '-') from the rule list presented to user space. Smack by design never removes labels nor rules from its lists. Access for a rule may be set to '-' to effectively disable it. Such rules would show up in the listing generated when /smack/load or /smack/load2 is read. This may cause clutter if many rules were disabled. As a rule with access set to '-' is equivalent to no rule at all, they may be safely hidden from the listing.

2012-07-13Smack: onlycap limits on CAP_MAC_ADMINCasey Schaufler
Smack is integrated with the POSIX capabilities scheme, using the capabilities CAP_MAC_OVERRIDE and CAP_MAC_ADMIN to determine if a process is allowed to ignore Smack checks or change Smack related data respectively. Smack provides an additional restriction that if an onlycap value is set by writing to /smack/onlycap only tasks with that Smack label are allowed to use CAP_MAC_OVERRIDE. This change adds CAP_MAC_ADMIN as a capability that is affected by the onlycap mechanism.

The locking is removed. Since this is the only place that lock was used the lock is removed from the superblock_smack structure. 3. smk_fill_super() incorrectly and unnecessarily set the Smack label for the smackfs root inode.

2012-05-14Smack: allow for significantly longer Smack labels v4Casey Schaufler
V4 updated to current linux-security#next Targeted for git://gitorious.org/smack-next/kernel.git Modern application runtime environments like to use naming schemes that are structured and generated without human intervention. Even though the Smack limit of 23 characters for a label name is perfectly rational for human use there have been complaints that the limit is a problem in environments where names are composed from a set or sources, including vendor, author, distribution channel and application name. Names like softwarehouse-pgwodehouse-coolappstore-mellowmuskrats are becoming harder to avoid. This patch introduces long label support in Smack. Labels are now limited to 255 characters instead of the old 23. The primary reason for limiting the labels to 23 characters was so they could be directly contained in CIPSO category sets. This is still done were possible, but for labels that are too large a mapping is required. This is perfectly safe for communication that stays "on the box" and doesn't require much coordination between boxes beyond what would have been required to keep label names consistent. The bulk of this patch is in smackfs, adding and updating administrative interfaces. Because existing APIs can't be changed new ones that do much the same things as old ones have been introduced. The Smack specific CIPSO data representation has been removed and replaced with the data format used by netlabel. The CIPSO header is now computed when a label is imported rather than on use. This results in improved IP performance. The smack label is now allocated separately from the containing structure, allowing for larger strings. Four new /smack interfaces have been introduced as four of the old interfaces strictly required labels be specified in fixed length arrays. The access interface is supplemented with the check interface: access "Subject Object rwxat" access2 "Subject Object rwaxt" The load interface is supplemented with the rules interface: load "Subject Object rwxat" load2 "Subject Object rwaxt" The load-self interface is supplemented with the self-rules interface: load-self "Subject Object rwxat" load-self2 "Subject Object rwaxt" The cipso interface is supplemented with the wire interface: cipso "Subject lvl cnt c1 c2 ..." cipso2 "Subject lvl cnt c1 c2 ..." The old interfaces are maintained for compatibility. Signed-off-by: Casey Schaufler <casey@schaufler-ca.com>

2012-04-03LSM: shrink the common_audit_data data unionEric Paris
After shrinking the common_audit_data stack usage for private LSM data I'm not going to shrink the data union. To do this I'm going to move anything larger than 2 void * ptrs to it's own structure and require it to be declared separately on the calling stack. Thus hot paths which don't need more than a couple pointer don't have to declare space to hold large unneeded structures. I could get this down to one void * by dealing with the key struct and the struct path. We'll see if that is helpful after taking care of networking.

2011-10-12Smack: Repair processing of fcntlCasey Schaufler
Al Viro pointed out that the processing of fcntl done by Smack appeared poorly designed. He was right. There are three things that required change. Most obviously, the list of commands that really imply writing is limited to those involving file locking and signal handling. The initialization if the file security blob was incomplete, requiring use of a heretofore unused LSM hook. Finally, the audit information coming from a helper masked the identity of the LSM hook.

2011-10-12Smack: Rule list lookup performanceCasey Schaufler
This patch is targeted for the smack-next tree. Smack access checks suffer from two significant performance issues. In cases where there are large numbers of rules the search of the single list of rules is wasteful. Comparing the string values of the smack labels is less efficient than a numeric comparison would. These changes take advantage of the Smack label list, which maintains the mapping of Smack labels to secids and optional CIPSO labels. Because the labels are kept perpetually, an access check can be done strictly based on the address of the label in the list without ever looking at the label itself. Rather than keeping one global list of rules the rules with a particular subject label can be based off of that label list entry. The access check need never look at entries that do not use the current subject label. This requires that packets coming off the network with CIPSO direct Smack labels that have never been seen before be treated carefully. The only case where they could be delivered is where the receiving socket has an IPIN star label, so that case is explicitly addressed. On a system with 39,800 rules (200 labels in all permutations) a system with this patch runs an access speed test in 5% of the time of the old version. That should be a best case improvement. If all of the rules are associated with the same subject label and all of the accesses are for processes with that label (unlikely) the improvement is about 30%.
