9 years agovolser: restructure GetNextVol and clients to remove duplicate code
Garrett Wollman [Sat, 28 Jul 2012 05:10:09 +0000]
volser: restructure GetNextVol and clients to remove duplicate code

There are several odd-looking but stylized loops involving GetNextVol()
which can be radically simplified if only GetNextVol() would return
a meaningful value.  Move all of the code that skips non-volume-header
files in the directory into GetNextVol and have it return a truth value
(instead of always returning zero) that indicates whether it saw
something that looks like a volume header.  Then all the odd while
loops and strcmps just collapse into while(GetNextVol(...)).

GetNextVol() had external scope, but there are no callers in the
tree that use it outside of volprocs.c, and it's not part of a
public library interface, so make it static.

While here, don't strcmp() past the end of a filename that begins with
'V' but is too short to be a valid volume name.

9 years agovos: Minimize release impact for new RO sites
Andrew Deason [Wed, 9 May 2012 23:45:51 +0000]
vos: Minimize release impact for new RO sites

Currently, if a new RO site is added with 'vos addsite', the only way
to populate the new site with data is a 'vos release' (excepting hacks
using 'vos restore' and 'vos addsite -live', etc). Due to safeguards
in 'vos' ensuring that RO sites always all contain the same data when
marked as up-to-date in the VLDB, such a release always incurs some
amount of data to be transmitted to all sites, as well as remote sites
being brought offline briefly, even when the RW data has not changed
in very long time.

To alleviate this situation, make 'vos release' detect if new,
unpopulated RO sites have been added, and if the RW volume has not
changed since the release of any existing RO sites. If both of these
conditions are true, do not update any of the existing sites, but only
transmit volume data to the sites that did not already contain RO
volumes.

vlserver: always use the hostaddress table in GetAddrsU

Use the hostaddress (IpMappedAddr) table when looking up hosts by IP
address and when listing addresses by index, instead of accessing
the multi-homed extensions directly.

The existing vos client calls the old GetAddrs rpc to first retrieve
a count of the number of addresses expected. This count is the
number of addresses in the hostaddress table.  If there are
unreferenced entries in the mh extension blocks, then vos can return
an incorrect or incomplete list of addresses.

To be consistent with the rest of the host address processing, use
the hostaddress table in GetAddrsU to lookup hosts by index or by IP
address.

The hostaddress table is already used when looking up addresses by
UUID.

not allocating any memory in this case but returning success, and in
the caller check for an empty list and avoid the pointless RPC to
translate no IDs into no names.  pr_IDListExpandedMembers() will return
success, as it previously did in the non-PRNOMEM case.

a function, so make sure that all of its callers cast NULL appropriately.
(None of them did.)  This may be an opportune time to change all of

9 years agoxdr: fix two old FIXMEs related to signed/unsigned arithmetic
Garrett Wollman [Sat, 21 Jul 2012 04:04:58 +0000]
xdr: fix two old FIXMEs related to signed/unsigned arithmetic

It's implementation-defined whether the C '>>' operator, when
applied to a signed integer, is sign-extending or zero-filling.
If you want unsigned arithmetic, you have to ask for it explicitly.
One assumes the reason for the shift is to avoid overflow if the
returned size/count is later converted to a signed int, in which
case maybe it would be better to use INT_MAX here.  This is the
minimal change necessary for correctness.

of making the store to "code" live again (and also makes it less

rx: eliminate dead variable sdl in rx_getAllAddr_internal()

Near as I can tell, sdl is only assigned once, and is never read.

9 years agoutil: LogCommandLine: argc is an int, so assert that it's positive
Garrett Wollman [Sun, 15 Jul 2012 18:09:11 +0000]
util: LogCommandLine: argc is an int, so assert that it's positive

In practice, argc should never be negative, but by convention it's
a signed int, so change the assertion to require it to be positive
rather than merely nonzero to get some help to the static analyzer.

malloc(0) is non-portable (may return a pointer to no space, or it

rx: don't leak a connection hash table in unlikely error condition

If getsockname() returns an error (which shouldn't be possible),
rx_InitHost would leak a connection hash table (which probably
doesn't matter because the caller will just exit anyway).  Make
the analyzer happy by freeing the memory anyway.

9 years agoviced: RXAFS_GetVolumeStatus remove access check
Jeffrey Altman [Tue, 3 Jul 2012 19:58:01 +0000]
viced: RXAFS_GetVolumeStatus remove access check

The AFS file server had always performed a PRSFS_READ permission
check on the volume's root directory (1.1) vnode before responding
succesfully to the client.  A successful response contains the
following volume state information:

  Message of the day (if any)
  Offline message (if any)
  Online flag
  InService flag
  Blessed flag
  NeedsSalvage flag
  Type
  MinQuota
  MaxQuota
  BlocksInUse
  PartBlocksAvail
  PartMaxBlocks

All of this information is publicly available to anonymous users
via other services so it is odd that it is hidden from anonymous
cache managers.

As sites begin to tighten the ACLs on volumes due to privacy
and security concerns this READ permission check is begin to
cause problems for Windows clients that rely upon the quota and
block counts to determine whether or not it is likely to be safe
to perform an extending write.  In many environments volumes are
being configured such that the root directory is 'l' for all and
only the subdirectories provide for 'ridw'.  Under these situations
the user is able to read/write the data but cannot determine how
much free space is available.  Since all of the data returned by
RXAFS_GetVolumeStatus is publicly available, the patchset removes
the access check entirely.
