This series replaces the usage of linked list in secret driver with a
hashed object list as was suggested in the review in the last patch of
the previous secret driver changes series:
http://www.redhat.com/archives/libvir-list/2016-February/msg01274.html
Patch 1 - starts the ball rolling
Patch 2 - is yet another code optimization (as found in bridge_driver)
Patches 3-8 - Add the new API's "slowly" (for review purposes)
Patch 9 - replaces the usage of linked lists with the hashed object
Patch 10 - moves the secretLoadAllConfigs to secret_conf
The changes are loosely modeled after both virdomainobj and network_conf
functionality. The real meat and potato(e)s is found in patches 5 and 9.
Other functions should be relatively straightforward.
I've done testing of various virsh secret-* commands (both valid and invalid
options) as well as performing driver start, stop, and reload testing.
Each patch was built using 'check' and 'syntax-check'.
The end result is much more code in secret_conf and much less in secret_driver.
John Ferlan (10):
secret: Move virSecretObj to secret_conf.h
Add secretObjFromSecret
secret: Add hashed virSecretObj and virSecretObjList
secret: Introduce virSecretObjListFindBy{UUID|Usage} support
secret: Introduce virSecretObjListAdd* and virSecretObjListRemove
secret: Introduce virSecretObjListNumOfSecrets
secret: Introduce virSecretObjListExport
secret: Introduce virSecretObjListGetUUIDs
secret: Use the hashed virSecretObjList
secret: Move and rename secretLoadAllConfigs

New subject: [libvirt] [PATCH 01/10] secret: Move virSecretObj to secret_conf.h
To support being able to create a hashed secrets list, move the
virSecretObj to secret_conf.h so that secret_conf.c can at least find
the definition.

I don't think this is necessary. You still can create accessors and have
the actual implementation of the struct private in the .c file. That way
it's guaranteed that nobody will touch the fields directly accross the
source files.

Suffice to say there's still more work to do; however, short term I
think it needs to move so I can make some progress. I will have a
followup series that will move _virSecretObj into secret_conf.c.
The goal for this series was to build up the code to support a hashed
secret object while still having that linked list in the driver. Patch
10 was added to this series mainly since it was discussed in danpb's
review of my last set of secret driver changes. Moving the saving of the
config file and secret data file was next on the todo list.
I should note that the existing model has virDomainObj in
src/conf/domain_conf.h and virNetworkObj in src/conf/network_conf.h, so
virSecretObj wouldn't be unique...
I honestly didn't want another 15-20 patch series floating around. Make
some progress, share, get buy in, continue. The question then becomes
does the rest of the series look good?

Precedence is a strong argument; so make mention of that in the commit
message. I'm personally okay with this patch, but I'll go ahead and
review the rest of the series first before deciding if attempting to use
accessors and keeping the struct private is worth a respin, or whether
to ack this as-is.

I'm comparing against src/conf/network_conf.c, which lists the two
objects prior to the two function forward declarations (that is, swap
lines 2 and 3 of the above).

I might have dropped the '!= NULL', but that's cosmetic.
+ memset(secret->value, 0, secret->value_size);
+ VIR_FREE(secret->value);
Maybe worth a comment that we intentionally wipe before free, to
minimize the chance of leaving a no-longer-used secret on the heap? The
name 'Secret' kind of makes it apparent why we spend the extra time
doing that, when most uses of VIR_FREE intentionally avoid the extra
wipe in the name of speed, but the comment may still be useful.
Addressing any of my comments shouldn't affect behavior, so:

It's safe to write:
return virObjectRef(virHashLookup(...));
since virObjectRef intentionally has sane handling of NULL. Of course,
you were just copying existing practice, and maybe the more verbose form
is arguably more legible, so I don't care if you change it. (Or maybe a
followup patch the other code you were copying from to use the compact
form...)

New subject: [libvirt] [PATCH 05/10] secret: Introduce virSecretObjListAdd* and virSecretObjListRemove
Add the functions to add/remove elements from the hashed secret obj list.
These will replace secret_driver functions secretAssignDef and secretObjRemove.
The virSecretObjListAddLocked will perform the necessary lookups and
decide whether to replace an existing hash entry or create a new one.
This includes setting up the configPath and base64Path as well as being
able to support the caller's need to restore from a previous definition
in case something goes wrong in the caller.
Need to also move and make global virSecretUsageIDForDef since it'll
be used by both secret_driver.c and secret_conf.c

This says we can't turn an existing public secret into a private one,
but nothing is protecting us from the converse of someone attempting to
redefine a private secret into a public one. I think this should be:

+

{

Redundant; the cleanup label also takes care of freeing configFile.
+ goto cleanup;
+ }
+
Everything else looked okay.

This says we can't turn an existing public secret into a private one,
but nothing is protecting us from the converse of someone attempting to
redefine a private secret into a public one. I think this should be:
if (secret->def->private != def->private)
This is a copy of current check in secretDefineXML...
The secret->def->private is our stored one and def->private is the new
one. As I'm reading it, it looks right; however, going with the
suggestion means one could not change either way (e.g. public->private
or private->public). Then again maybe I'm reading your comment wrong.
FWIW: I've changed the name later to "isprivate" to make it clearer (and
to avoid that potential magic word private).

On 03/02/2016 11:55 AM, John Ferlan wrote:
Add function to return a "match" filtered list of secret
objects. This
function replaces the guts of secretConnectListAllSecrets.
Need to also move and make global virSecretUsageIDForDef since it'll
be used by both secret_driver.c and secret_conf.c

I could go the route of a "virsecretobj.c" (to partially mimic the
virdomainobjlist.c) instead of cramming everything into secret_conf -
there's about 1000 new lines in secret_conf just for this series (with
the reduction of lines in secret_driver).
It would mean a complete v2 of this series - although considering most
things have been ACK'd the second review should be easier. I think
there's only a couple of issues/questions to resolve from reviews.
Thanks for the review -

Oh I wasn't trying to imply making it a requirement of this series. Definitely
an additive thing, and I'm not even trying to pin you with the work, just

Understood - I'd rather do it now than take a hit at some unknown future
point in time to essentially do the same thing. In the long run it's the
"right thing" to do.

Yeah but I hate to see self contained changes get held up just to accommodate
an additional cleanup. Reviewer bandwidth is the bottleneck here

This comment seems weirdly placed now. If it's kept at all it should be placed
at the ObjDeleteData call sites. Or rework it as a comment in ObjDeleteData to
explain why we don't care about failure in this case.

This should report have a virReportSystemError call. The original code doesn't
have one, but that's a bug
Minor stuff though so ACK in general, I don't care if you fix before pushing
but not sure if there's a formal policy on that

Though there should probably be explicit virfile.c support for a generic

'rewrite file with this passed string', rather than requiring a callback.
src/network/leaseshelper.c already has something similar
This patch was just moving existing code. I cannot say for sure, but if
the 'opaque' data had some formatting considerations rather than just a
string, such as virXMLSaveFile which also uses virFileRewrite, then the
existing virFileRewrite is doing just what it was designed to do. I
didn't spend any cycles looks which came first.

New subject: [libvirt] [PATCH 14/10] secret: Introduce virSecretObjGetValue and virSecretObjGetValueSize
Introduce the final accessor's to _virSecretObject data and move the
structure from secret_conf.h to secret_conf.c
The virSecretObjSetValue logic will handle setting both the secret
value and the value_size. Some slight adjustments to the error path
over what was in secretSetValue were made.
Additionally, a slight logic change in secretGetValue where we'll
check for the internalFlags and error out before checking for
and erroring out for a NULL secret->value. That way, it won't be
obvious to anyone that the secret value wasn't set rather they'll
just know they cannot get the secret value since it's private.

This series replaces the usage of linked list in secret driver with

hashed object list as was suggested in the review in the last patch of
the previous secret driver changes series:
http://www.redhat.com/archives/libvir-list/2016-February/msg01274.html
Patch 1 - starts the ball rolling
Patch 2 - is yet another code optimization (as found in bridge_driver)
Patches 3-8 - Add the new API's "slowly" (for review purposes)
Patch 9 - replaces the usage of linked lists with the hashed object
Patch 10 - moves the secretLoadAllConfigs to secret_conf
The changes are loosely modeled after both virdomainobj and network_conf
functionality. The real meat and potato(e)s is found in patches 5 and 9.
Other functions should be relatively straightforward.
I've done testing of various virsh secret-* commands (both valid and invalid
options) as well as performing driver start, stop, and reload testing.
Each patch was built using 'check' and 'syntax-check'.
The end result is much more code in secret_conf and much less in secret_driver.
John Ferlan (10):
secret: Move virSecretObj to secret_conf.h
Add secretObjFromSecret
secret: Add hashed virSecretObj and virSecretObjList
secret: Introduce virSecretObjListFindBy{UUID|Usage} support
secret: Introduce virSecretObjListAdd* and virSecretObjListRemove
secret: Introduce virSecretObjListNumOfSecrets
secret: Introduce virSecretObjListExport
secret: Introduce virSecretObjListGetUUIDs
secret: Use the hashed virSecretObjList
secret: Move and rename secretLoadAllConfigs

Ping - any chance these can be finished up? Would it be better to
repost the entire series. It should apply cleanly as there hasn't been
changes in this space.
