Stephan Wiesand [Wed, 7 May 2014 13:20:51 +0000]
redhat: Use the right path to depmod

As of Fedora 17 and RHEL 7, depmod has moved from /sbin to /usr/sbin.
The full path to depmod is used in package scripts and as a dependency.
This hasn't caused problems in most cases because on an installed
system a link /sbin -> /usr/sbin is present and during ordinary package
installations yum/rpm correctly then figure out that /sbin/depmod is
actually provided. But in other situations, the dependency check is not
that clever and (incorrectly) fails.

Add a macro to the spec defining the full path to depmod, use the macro
rather than plain /sbin/depmod throughout the spec, and also pass it to
kmodtool when required to generate the kmod package scripts and
requirements.

Linux: Prevent some fakestat data inconsistencies

When fakestat is enabled for a mount point, the parent vcache
entry is not the right place to find the DataVersion of
the target volume root directory.  This can lead to data
inconsistency since the revalidation checks rely on the parent's
DataVersion to determine if a file entry is still valid.  If the
file was replaced or deleted remotely, the only callback we
get is for the parent directory, and in that case the client
will think the file entry is still valid and give back stale
data to the user.

If fakestat is enabled and we have a mountpoint, always use
the parent vcache pointer returned by FakeStat before using it
to either store (in the lookup and create ops) or compare
(in the revalidate op) the DataVersion.

Rod Widdowson [Sun, 4 May 2014 18:33:11 +0000]
Windows: Adjust Last Write time handling for -1

The "what date/time gets changed when and by whom" in Windows is badly
defined, but all filesystems support the semantic that if a date is set
using a specific file object (or the timestamp is set to the magic number
-1)
then other changes provoked by that file object will be ignored.

AFS redirector timestamp handling does not support this behavior.
For the LastWrite timestamp (other timestamps are pretty much advisory and
maintained on a best effort basis) the timestamp would be updated by a
write operation even after -1 is set via the file handle.

This patchset implements the -1 behavior for LastWrite.  It also follows
the standard Windows practice of setting the LastWrite timestamp to be the
time of close of the handle that performed the write, not the time of the
write itself.

Finally, it should be noted that since RX*FS_StoreXXX operations update
the last write time on the server the client must restore the LastWrite
timestamp at handle close if -1 was specified.

10 years agoFix rx_EndCall error precedence
Andrew Deason [Thu, 30 Jan 2014 19:50:11 +0000]
Fix rx_EndCall error precedence

Callers of rx_EndCall in various parts of the code handle errors a bit
differently from each other. The correct way to use rx_EndCall is
almost always some form of:

    code = rx_EndCall(call, code);

This will cause the call to abort with 'code' if the call is not
already aborted, and will return the abort code for the call (or 0 if
the call ended successfully). It is thus impossible for 'code' to
start out with a non-zero value in the code snippet above, and end up
with a value of 0 after the code snippet.

Most code follows this pattern, because this is how the
rxgen-generated client RPC wrappers are written. So for any non-split
Rx call, this is how the error precedence works.

However, some code (mostly for Rx split calls), needs to handle
calling rx_EndCall itself, and some code appears to think it is
possible for rx_EndCall to return 0 when we already had a non-zero
error. Such code tries to ensure that we don't ignore an error we
already got by doing something like this:

    code2 = rx_EndCall(call, code);
    if (code2 && !code) {
        code = code2;
    }

However, this is not correct. If a call gets killed with an abort code
partway through executing an RPC, and the client tries to end the RPC
with e.g. EndRXAFS_FetchData, the client will get an error code of
-451 (RXGEN_CC_UNMARSHAL). The actual error code is in the abort code
for the call, but with the above 'code2' snippet, we can easily return
an error of -451 instead, which will usually get interpreted as some
unknown network-related error.

This can manifest as a problem in the unix client, where if a
FetchData call fails due to, for example, an "idle dead" timeout, we
should result with an error code of RX_CALL_TIMEOUT. But because of
the above issue, we'll instead yield an error of -451, causing the
server to be marked down with the following message:

    afs: Lost contact with file server ... (code -451) ...

So, fix most rx_EndCall callers to follow the 'code = rx_EndCall(call,
code);' pattern. Not all of the changes here are to "wrong" code, but
try to make all of the rx_EndCall call sites look more consistent.
There are a few exceptions to this pattern, which warrant some
variations:

 - A few instances in src/WINNT/afsd/cm_dcache.c do seem to want to
   record the original error before we ran rx_EndCall, instead of
   seeing the rx abort code. We still return the rx_EndCall-returned
   value to the caller, though.

 - Any caller of RXAFS_FetchData* needs to read a 'length' raw from
   the rx split stream. If this fails, we need to abort the call, but
   we don't really have an error code to give to rx_EndCall. Failure
   to read a length indicates that the server is not following
   protocol properly, so give rx_EndCall RX_PROTOCOL_ERROR in these
   instances. The call should already be aborted by this point, so
   most of the time this code will be ignored; it will only make a
   difference if the server tries to end the call successfully without
   sending a length, which is indeed a protocol error.

 - Some Rx clients can encounter a local error they don't want to send
   to the server via an abort, so they just end the call successfully,
   and only use the rx abort code if they don't already have a local
   error. This is in a few places like src/butc/dump.c and
   src/volser/vsprocs.c.

 - Several places don't care what the error from rx_EndCall is, such
   as various call sites in server-side code.

The behavior of the Windows client w.r.t rx_EndCall was changed a bit
into its current behavior in commit
a50fa631cad6919d15721ac2c234ebbdda2b4031 (ticket 125018), which just
appears to be wrong. This was partially reverted by commit
ae7ef5f5b963a5c8ce4110a7352e0010cb6cdbc1 (ticket 125351), but some of
the other call sites were unchanged. The Unix client appears to have
been doing this incorrectly for at least FetchData calls since OpenAFS
1.0.

To make it hopefully more clear that rx_EndCall cannot return 0 if
given a non-zero error code, add an assert to rx_EndCall that asserts
that fact.

viced: disable hot threads

Turn off the rx hot threads feature in the file server.  This feature
was an old optimization intended to reduce context switching, however
generally makes performance worse on modern hardware.

Performance improvements from disabling hot threads was identified by

2014 at CERN.

10 years agoviced: Restore some previous log message language
Andrew Deason [Wed, 26 Feb 2014 17:42:16 +0000]
viced: Restore some previous log message language

Before commit 6c41b1f740e16b5b9adfe9026630595be6f0699e, we logged
these three messages in the fileserver in different situations:

  CallPreamble: Couldn't get client.
  CallPreamble: Couldn't get CPS. Fail
  CallPreamble: couldn't reconnect to ptserver

After commits 6c41b1f740e16b5b9adfe9026630595be6f0699e and
0a5e878aa0a71c4dfaef1806744ed78bcc13b9f4, these messages were changed
to contain more useful information, but the language was also changed.
The messages now look like:

  Client host too busy while handling request from host %s:%d viceid %d fid %lu.%lu.%lu, failing request
  Cannot get CPS for client while handling request [...], failing request
  Cannot reconnect to ptserver while handling request [...], failing request

While the new messages are more informative, and (in my opinion)
better describe what is happening in those situations, they do look
very different from the old messages. This can break scripts that try
to parse these logs, but in general it is also not clear to
administrators that these messages still refer to the same events.

So instead, put these messages back the way they were. Still include
the extra information, of course, but revert the language to look more
like the old messages. Now we log:

  CallPreamble: Couldn't get client while handling request from host %s:%d viceid %d fid %lu.%lu.%lu, failing request
  CallPreamble: Couldn't get CPS while handling request [...], failing request
  CallPreamble: couldn't reconnect to ptserver while handling request [...], failing request

Thanks to Ben Kaduk for bringing this up.

Linux: Do drop dentry if lookup returns ENOENT

Commit 997f7fce437787a45ae0584beaae43affbd37cce switched to using
d_invalidate instead of d_drop to prevent unhashing dentries
which are only temporarily invalid and may still be referenced
by someone having a current working directory pointing to it.
This could result in getting ENOENT from getcwd() after some
transient problems, even when the directory is there and
accessible.

The change had the side effect of potentially leaving something
visible when it has actually been removed, for instance a mountpoint
removed by "fs rm".

If afs_lookup returns ENOENT, we want to forcibly drop (unhash)
the dentry, even if it has current users.

10 years agovos: GetServer search for non-loopback address
Jeffrey Altman [Sun, 15 Dec 2013 00:38:50 +0000]
vos: GetServer search for non-loopback address

GetServer() is used to obtain an IP address for the 'aname' parameter.
'aname' can be either a dotted address or a host name.   If it is a dotted
address, it is returned immediately.  If it is a host name, then
gethostbyname() is used to obtain an IP address.

The prior version of this function had two failings:

1. It assumed that a struct hostent only contained a single address.
   It used the former h_addr field.  For all platforms supported by
   OpenAFS h_addr is a macro referencing the first address in the
   h_addr_list array.  If h_addr was a loopback address, it would
   ignore any additional addresses that might be in the list.

2. It assumed that if gethostbyname(aname) returned a loopback
   address as h_addr that 'aname' must be referring to the machine
   that the vos command is being executed on.  It therefore used
   gethostname() to obtain an alternate name to use for a gethostbyname()
   query.  The results of this query were not checked to be a loopback.
   As a result, a loopback address could be returned to the caller which
   in turn could be set into the VLDB.

10 years agolibafs: DARWIN: update for Xcode 5.1
Benjamin Kaduk [Fri, 14 Mar 2014 15:13:15 +0000]
libafs: DARWIN: update for Xcode 5.1

(1) remove -mlong-branch from amd64 build

Random internet postings suggest that it has triggered a warning
since at least Xcode 3.2, and the gcc manual page suggests that
it is only applicable on ppc, anyway.

(2) remove -mpreferred-stack-boundary=4 from the amd64 build

The evidence here shows up less readily in an internet search,
but it seems that Apple's compilers will force the stack alignment
to 16 bytes regardless of what is passed here.  One poster had
trouble with -mpreferred-stack-boundary being unused in Xcode 4.4.1

This change only fixes warnings reported as errors by buildbot; it
does not attempt to fully synchronize with the flags that Xcode 5.1
uses for kernel module builds.

afs_fetchstore: re-avoid uninitialized variable

As noted in the gerrit comments for change 10742, commit
baf6af8a8f2207ce39b746d59ca4bc661c002883 does not handle the case
where the second rx_Read() call fails, and the 'length' variable
can still be used uninitialized.

Instead of using an err label and jumping to it on the case of
errors, initialize length to zero and take care to neither
set nor access *alength if an error has occurred.  This is
more consistent with the style of the surrounding code while still
avoiding the use of an uninitialized variable.
