9 years agocmd: Add accessor functions for options
Simon Wilkinson [Tue, 19 Apr 2011 10:41:54 +0000]
cmd: Add accessor functions for options

Add a load of accessor functions to help with pulling values out
from the the cmd_syndesc structure. The idea here is to make it
simpler to manipulate command line values, as well as starting to
hide the structure of the cmd_syndesc structure from callers, with
a view to eventually making it private to the cmd library.

9 years agocmd: Add option to add a param at a specific pos
Simon Wilkinson [Tue, 19 Apr 2011 08:01:25 +0000]
cmd: Add option to add a param at a specific pos

Rather than having to use cmd_Seek, followed by cmd_AddParam,
followed by another cmd_Seek, add a function which permits parameters
to be added at specific reference points. This allows programs to
declare a list (either as an enum or specific #defines) of parameter
code points, rather than using raw numbers.

9 years agoAdd -usetokens option to libadmin test 'afscp'
Thomas L. Kula [Sun, 6 Feb 2011 01:11:56 +0000]
Add -usetokens option to libadmin test 'afscp'

This adds a -usetokens option to poorly named libadmin test 'afscp' program.
If called with this flag, 'afscp' will assume you have already acquired
tokens, and will fetch and use them. If ran with the -authcell option,
it will look for tokens for that cell, otherwise it will look for tokens
in the local cell. Since the function used to fetch local tokens is
incompatable with the kas functions, all of the kas commands have been
modified to complain and exit if any of them all called with -usetokens.

Fixed whitespace, again.

ubik: always hold DB lock for urecovery_ResetState()

ubik_ResetState requires callers to hold the DB lock, since it modifies

call to ResetState, and have the callers take the DB lock and call
ResetState themselves if needed.  They can take the lock in this case
because we know we're not the sync site.  Refactor the exported

Marc Dionne [Sat, 16 Apr 2011 16:56:05 +0000]
ubik: set UBIK_RECLABELDB before propagating version

Quoting Jeffrey Hutzelman:

In udisk_commit(), when committing the first write transaction
after becoming sync site, the database is relabelled.  In this
case, the UBIK_RECLABELDB recovery state bit should be set before
propagating the label change to other servers, rather than after.

This is because ContactQuorum_DISK_Setversion() will
release the database lock, at which point the recovery state may
be cleared by urecovery_ResetState() running in another thread.
It is important that a relabelling which occurs before recovery
state is cleared not result in the UBIK_RECLABELDB recovery state
bit being set after; otherwise, the server may fail to correctly
relabel the database the next time it becomes sync site.

This clears up the warnings by doing the following:
- Cast "user" to char * when kalling ka* functions
- Change the signature of pam_afs_prompt and pam_afs_printf to use
PAM_CONST

9 years agoLinux: Restrict # of cbrs we allocate at once
Simon Wilkinson [Thu, 21 Apr 2011 15:07:05 +0000]
Linux: Restrict # of cbrs we allocate at once

With commit a309e274632993c5aeec04c6e090f5ac95837a40, we changed the
number of CBRs that we allocate in a chunk from 300 to 1024. However,
this change takes the amount of memory requried to allocate a chunk
of CBRs above PAGE_SIZE on Linux. This changes the allocator that we
use from kmalloc to vmalloc. Whilst we can, and do, prevent kmalloc
from flushing filesystem pages when we invoke it, we don't have a
similar level of control over vmalloc.

In one reported case, clients deadlock whilst attempting to allocate
this memory, in a call stack that looks something like:

  afs_Daemon -> afs_ShakeLooseVCaches -> osi_TryEvictVCache
      -> afs_FlushVCache -> afs_QueueVCB -> afs_AllocCBR
      -> osi_linux_alloc -> ... -> __vmalloc_node -> ...
      -> try_to_free_pages

This is probably because we end up deadlocking in the writeback
invoked by try_to_free_pages, likely due to locks which are held
by ShakeLooseVCaches.

As a quick fix for the problem, make sure that the memory we
allocate always fits within a page, so we always use kmalloc for
it.

afsio: rewrite using libafscp

afsio is a utility for file transfer to and from AFS file space
without the help of the AFS client/cache manager.  Using libafscp,
this (partially rewritten) version of afsio is able to accomplish
(1) authenticated access to an AFS path or FID (an existing
KerberosV ticket is required), (2) fall back on unauthenticated
("anonymous") access if authentication (token acquisition) fails,
and (3) work independtly of the AFS cache manager (afsd need not
be running, though CellServDB and ThisCell are currently required).

issues:
1) libvldbint and libafsint are not compiled pthreaded. we link in
what we need. this should be changed when we are all-pthreaded.
2) venus is not a pthreaded-directory otherwise. same deal:

3) venus is not an all-krb5 directory either. slight ick.

Andrew Deason [Wed, 6 Apr 2011 21:56:22 +0000]
afsd: Trim trailing slashes on Linux mntent

When we write a mount entry on Linux when mounting /afs, trim trailing
slashes on the mount path. Otherwise, the umount utility can get
slightly confused, and leave the /afs mount entry in /etc/mtab after
it's been unmounted.

For full correctness we should probably completely canonicalize the
path like the mount utility does, but it's unlikely that anyone will
provide significantly weird paths for cacheMountDir, so don't bother.

9 years agosalvager: Do not AskDelete on GetInodeSummary fail
Andrew Deason [Thu, 31 Mar 2011 17:51:44 +0000]
salvager: Do not AskDelete on GetInodeSummary fail

GetInodeSummary can fail due to a number of different reasons, not
just because the VG doesn't exist. If, for example, we just fail to
write the temporary inode file, we will return with an error, but we
should not AskDelete the volume in that instance.

GetInodeSummary already has code to delete the volumes in question
when no inodes are found, so remove the extra AskDelete after
GetInodeSummary returns.

9 years agosalvager: Error volumes on GetInodeSummary errors
Andrew Deason [Thu, 31 Mar 2011 22:22:12 +0000]
salvager: Error volumes on GetInodeSummary errors

When GetInodeSummary fails due to an internal failure (not from just
failing to find applicable inodes), currently it just returns an
error, and does not return the checked-out singleVolumeNumber back to
the fileserver.

When we fail to gather inodes, we should force the volume to an error
state, since we haven't salvaged the volume. But if we fail to find
any applicable inodes, we just want to VOL_DONE the volume, since the
header has possibly been destroyed, and the volume doesn't exist.

So, issue an FSYNC_VOL_FORCE_ERROR command when we encounter errors in
GetInodeSummary, except when we fail to find applicable inodes.

9 years agoubik: don't rely on timeout value after select()
Marc Dionne [Wed, 6 Apr 2011 01:30:20 +0000]
ubik: don't rely on timeout value after select()

The value of timeout after a select() call should be considered
undefined; relying on its value is not portable.
Since IOMGR_Select doesn't modify the timeout it is given, the
intention of the code seems to be to wait for gradually increasing
timeout values, starting at 50ms.  At least under Linux, the
timeout gets set to 0 by select() if it waited for the full specified
time, resulting in a much shorter maximum possible wait period.

Initialize the timeout value for each loop according to the existing
logic, to get consistent behaviour between the lwp and pthreaded code.
