The userspace cifs.idmap program generally works with the wbclient libs to generate binary SIDs in userspace. That program defines the struct that holds these values as having a max of 15 subauthorities. The kernel idmapping code however limits that value to 5. When the kernel copies those values around though, it doesn't sanity check the num_subauths value handed back from userspace or from the server. It's possible therefore for userspace to hand us back a bogus num_subauths value (or one that's valid, but greater than 5) that could cause the kernel to walk off the end of the cifs_sid->sub_auths array. Fix this by defining a new routine for copying sids and using that in all of the places that copy it. If we end up with a sid that's longer than expected then this approach will just lop off the "extra" subauths, but that's basically what the code does today already. Better approaches might be to fix this code to reject SIDs with >5 subauths, or fix it to handle the subauths array dynamically. At the same time, change the kernel to check the length of the data returned by userspace. If it's shorter than struct cifs_sid, reject it and return -EIO. If that happens we'll end up with fields that are basically uninitialized. Long term, it might make sense to redefine cifs_sid using a flexarray at the end, to allow for variable-length subauth lists, and teach the code to handle the case where the subauths array being passed in from userspace is shorter than 5 elements. Note too, that I don't consider this a security issue since you'd need a compromised cifs.idmap program. If you have that, you can do all sorts of nefarious stuff. Still, this is probably reasonable for stable. Cc: stable@kernel.org Reviewed-by: NShirish Pargaonkar <shirishpargaonkar@gmail.com> Signed-off-by: NJeff Layton <jlayton@redhat.com>

Give the key type the opportunity to preparse the payload prior to the instantiation and update routines being called. This is done with the provision of two new key type operations: int (*preparse)(struct key_preparsed_payload *prep); void (*free_preparse)(struct key_preparsed_payload *prep); If the first operation is present, then it is called before key creation (in the add/update case) or before the key semaphore is taken (in the update and instantiate cases). The second operation is called to clean up if the first was called. preparse() is given the opportunity to fill in the following structure: struct key_preparsed_payload { char *description; void *type_data[2]; void *payload; const void *data; size_t datalen; size_t quotalen; }; Before the preparser is called, the first three fields will have been cleared, the payload pointer and size will be stored in data and datalen and the default quota size from the key_type struct will be stored into quotalen. The preparser may parse the payload in any way it likes and may store data in the type_data[] and payload fields for use by the instantiate() and update() ops. The preparser may also propose a description for the key by attaching it as a string to the description field. This can be used by passing a NULL or "" description to the add_key() system call or the key_create_or_update() function. This cannot work with request_key() as that required the description to tell the upcall about the key to be created. This, for example permits keys that store PGP public keys to generate their own name from the user ID and public key fingerprint in the key. The instantiate() and update() operations are then modified to look like this: int (*instantiate)(struct key *key, struct key_preparsed_payload *prep); int (*update)(struct key *key, struct key_preparsed_payload *prep); and the new payload data is passed in *prep, whether or not it was preparsed.

Now build security descriptor to change either owner or group at the server. Initially security descriptor was built to change only (D)ACL, that functionality has been extended. When either an Owner or a Group of a file object at the server is changed, rest of security descriptor remains same (DACL etc.). To set security descriptor, it is necessary to open that file with permission bits of either WRITE_DAC if DACL is being modified or WRITE_OWNER (Take Ownership) if Owner or Group is being changed. It is the server that decides whether a set security descriptor with either owner or group change succeeds or not.

Add data structures and functions necessary to map a uid and gid to SID. These functions are very similar to the ones used to map a SID to uid and gid. This time, instead of storing sid to id mapping sorted on a sid value, id to sid is stored, sorted on an id. A cifs upcall sends an id (uid or gid) and expects a SID structure in return, if mapping was done successfully. A failed id to sid mapping to EINVAL. This patchset aims to enable chown and chgrp commands when cifsacl mount option is specified, especially to Windows SMB servers. Currently we can't do that. So now along with chmod command, chown and chgrp work. Winbind is used to map id to a SID. chown and chgrp use an upcall to provide an id to winbind and upcall returns with corrosponding SID if any exists. That SID is used to build security descriptor. The DACL part of a security descriptor is not changed by either chown or chgrp functionality. cifs client maintains a separate caches for uid to SID and gid to SID mapping. This is similar to the one used earlier to map SID to id (as part of ID mapping code). I tested it by mounting shares from a Windows (2003) server by authenticating as two users, one at a time, as Administrator and as a ordinary user. And then attempting to change owner of a file on the share. Depending on the permissions/privileges at the server for that file, chown request fails to either open a file (to change the ownership) or to set security descriptor. So it all depends on privileges on the file at the server and what user you are authenticated as at the server, cifs client is just a conduit. I compared the security descriptor during chown command to that what smbcacls sends when it is used with -M OWNNER: option and they are similar.

Set security descriptor using path name instead of a file handle. We can't be sure that the file handle has adequate permission to set a security descriptor (to modify DACL). Function set_cifs_acl_by_fid() has been removed since we can't be sure how a file was opened for writing, a valid request can fail if the file was not opened with two above mentioned permissions. We could have opted to add on WRITE_DAC and WRITE_OWNER permissions to file opens and then use that file handle but adding addtional permissions such as WRITE_DAC and WRITE_OWNER could cause an any open to fail. And it was incorrect to look for read file handle to set a security descriptor anyway.

rb tree search and insertion routines. A SID which needs to be mapped, is looked up in one of the rb trees depending on whether SID is either owner or group SID. If found in the tree, a (mapped) id from that node is assigned to uid or gid as appropriate. If unmapped, an upcall is attempted to map the SID to an id. If upcall is successful, node is marked as mapped. If upcall fails, node stays marked as unmapped and a mapping is attempted again only after an arbitrary time period has passed. To map a SID, which can be either a Owner SID or a Group SID, key description starts with the string "os" or "gs" followed by SID converted to a string. Without "os" or "gs", cifs.upcall does not know whether SID needs to be mapped to either an uid or a gid. Nodes in rb tree have fields to prevent multiple upcalls for a SID. Searching, adding, and removing nodes is done within global locks. Whenever a node is either found or inserted in a tree, a reference is taken on that node. Shrinker routine prunes a node if it has expired but does not prune an expired node if its refcount is not zero (i.e. sid/id of that node is_being/will_be accessed). Thus a node, if its SID needs to be mapped by making an upcall, can safely stay and its fields accessed without shrinker pruning it. A reference (refcount) is put on the node without holding the spinlock but a reference is get on the node by holding the spinlock. Every time an existing mapped node is accessed or mapping is attempted, its timestamp is updated to prevent it from getting erased or a to prevent multiple unnecessary repeat mapping retries respectively. For now, cifs.upcall is only used to map a SID to an id (uid or gid) but it would be used to obtain an SID for an id.

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

Thus spake Christoph: "But this whole set_cifs_acl function is a real mess anyway and needs some splitting up." With this change too, it's possible to call acl_to_uid_mode() with a NULL inode pointer. That (or something close to it) will eventually be necessary when cifs_get_inode_info is reorganized.

The current definition of wksidarr works fine on little endian arches (since cpu_to_le32 is a no-op there), but on big-endian arches, it fails to compile with this error: error: braced-group within expression allowed only inside a function The problem is that this static declaration has cpu_to_le32 embedded within it, and that expands into a function macro. We need to use __constant_cpu_to_le32() instead.
