[Samba] ANNOUNCE: cifs-utils release 5.8 is ready for download
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Time for another cifs-utils release!
Most of the patches in this release are for cifs.idmap, getcifsacl and
setcifsacl. There were many bugs in those tools, so anyone that's
deploying or using them is highly encouraged to upgrade.
Highlights:
* NFS-style device names are being deprecated in 6.0. Anyone using that
sort of device name should move to the UNC-style syntax that the manpage
has always documented.
* Many bugs in cifs.idmap, getcifsacl and setcifsacl have been fixed.
These tools should also be more efficient now and work correctly on
big-endian architectures.

cifs.idmap: make sure cifsacl structs are packed
The kernel equivalent definitions are defined with
__attribute__((packed)), and the code seems to assume the userspace and
kernel ones will be properly aligned. Fix the userspace definitions in a
similar fashion.
Given the way these structs are, there is probably not any padding
between fields on most arches, but it's best to be safe here.

cifs.idmap: get rid of useless strcmp prior to idmapping
The code copies off the key description and then ensures that it's
prefixed with "cifs.idmap". What's the point of that?
Presumably request-key would never have called this otherwise. There's
little harm in going ahead and doing the idmapping if this is called
with the wrong string.
Also, the error handling here is wrong. If the prefix doesn't match
the code will exit 0 without doing any mapping. Just remove it.

setcifsacl: clean up sizing of cifs_sid
The max number of subauthorities on windows and in winbind is generally
15, not 5. If winbind sends more than 5, then this code may end up
overrunning the buffer. Also, define some preprocessor constants and
use those instead of hardcoding '5' and '6' all over the
place.

setcifsacl: fix overrun of subauths array when copying SIDs
copy_sec_desc() copies the owner and group SIDs from one security
descriptor to another. Unfortunately, it doesn't take into account the
fact that these are variable length and routinely overruns the SID
structure when doing this copy and scribbles over the destination ACL.
This wasn't noticed before the change in the maximum number of subauths
because the code either overwrote the damage afterward, or the overrun
part was the same between source and destination anyway. Now that the
max number of subauths is 15, it's more noticable.
Fix it to only copy the number of subauths that claimed in the buffer
instead.

setcifsacl: fix up getopt() usage
'?' has a special meaning in getopt(). It means that the option
character was not recognized. You can override that behavior by making
':' the first character of the optstring, but that wasn't done
here. I'm
not sure what the effect of having '?' in the actual optstring is in
this case, but it's probably best not to put it in there.
Remove '?' from the optstring and replace it 'h'. Also add
'-h' as a
valid option to the manpage.
'-v' doesn't require an argument, so fix the optstring to
reflect that.
Finally declare a new variable to hold optarg. Currently we only call
getopt() once, which is a little odd. Eventually we may want to make it
call it more than once, in which case we'll need some way to store the
optarg on each pass.

setcifsacl: fix endianness on SIDs provided by winbind routines
Winbind keeps SID fields in host-endian format, but setcifsacl doesn't

the server will expect. The other fields are single bytes and don't
need conversion.

in all of these structs are always kept in little-endian.

setcifsacl: clean up parse_cmdline_aces
One of the reasons to use "goto" in an error condition is to
eliminate
unnecessary indentation. Fix that here by revering some error checks
end getting rid of some unneeded "else" cases.
After using strstr() to find "ACL:", there's no need to then
use
strchr() to find ':'. We know where it is -- it's 3 bytes past
the
current position.
Finally, there's no need to copy these strings into new buffers,
just set the pointers in the array to their original values.

setcifsacl: fix verify_ace_sid
The current method of trying to convert a name to a password struct and
then back to a SID is just weird. It also doesn't seem to work
correctly.
Instead, look for a '\\' in the string. If there isn't one then
try to
convert it directly to a SID.
If there is a '\\' or the direct-to-SID conversion didn't work,
then
use wbcLookupName to do the conversion directly to a SID instead.
Also, fix the error handling. These routines return a wbcErr, so we
should use their macros to check whether it worked or not.

setcifsacl: fix some bugs in build_fetched_aces
Pavel Raiskup reported the following defects that he found with Coverity:
"If the variable 'facesptr' on line
cifs-utils-4.8.1/setcifsacl.c|365|
has not enough memory to be allocated, program 'setcifsacl' will
fail
with segfault on line 365 (dereferencing facesptr)."
"you may return freed pointer here. There is some kind of return code
('rc') which should be transferred to >NULL< when is rc
nonzero (and
returned)"
There are also a couple of other bugs here:
malloc doesn't necessarily set errno to anything when an allocation
fails, so having the error handling rely on that is wrong.
Fix all of these bugs by reorganzing this function to fix up the error
handling.

setcifsacl: fix some bugs in build_cmdline_aces
Pavel Raiskup found the following defect in setcifsacl with Coverity:
"segfault may occur also in cifs-utils-4.8.1/setcifsacl.c|644| because
of casesptr dereferencing. When you look e.g. at the line 605, in this
time any part of 'caseptr' may be yet uninitialized and program is
going
through 'goto' to freeing -> and there you are freeing the
'caseptr[i]'
address."
The analysis there seems a little off, but is basically correct. The
freeing loop counts down from the current value of i to free the
secondary allocations here.
There is one situation though where this could go badly. If the strtok
parsing near the beginning of the loop fails, then we could end up
trying to free an uninitialized pointer.
Fix this by changing the cacesptr allocation to use calloc(), and stop
trying to be clever with the freeing loop. Just have it walk the
entire array and attempt to free each slot.
