scsi: libfc: Move scsi/fc_encode.h to libfc

2020-10-30T01:49:25+00:00

Most of this file is only used inside of libfc, so move it to where it is actually used, with only fc_fill_fc_hdr() left inside of the header.

networking: convert many more places to skb_put_zero()

2017-06-16T15:48:35+00:00

There were many places that my previous spatch didn't find, as pointed out by yuan linyu in various patches. The following spatch found many more and also removes the now unnecessary casts: @@ identifier p, p2; expression len; expression skb; type t, t2; @@ ( -p = skb_put(skb, len); +p = skb_put_zero(skb, len); | -p = (t)skb_put(skb, len); +p = skb_put_zero(skb, len); ) ... when != p ( p2 = (t2)p; -memset(p2, 0, len); | -memset(p, 0, len); ) @@ type t, t2; identifier p, p2; expression skb; @@ t *p; ...

scsi: libfc: Replace ->seq_start_next callback with function call

2016-11-08T22:29:56+00:00

The ->seq_start_next callback only ever had one implementation, so call the function directly and drop the callback. Signed-off-by: Hannes Reinecke Acked-by: Johannes Thumshirn Signed-off-by: Martin K. Petersen

libfc: Replace rcu_assign_pointer() with RCU_INIT_POINTER()

2014-09-30T07:28:36+00:00

The uses of "rcu_assign_pointer()" are NULLing out the pointers. According to RCU_INIT_POINTER()'s block comment: "1. This use of RCU_INIT_POINTER() is NULLing out the pointer" it is better to use it instead of rcu_assign_pointer() because it has a smaller overhead. The following Coccinelle semantic patch was used: @@ @@ - rcu_assign_pointer + RCU_INIT_POINTER (..., NULL) Signed-off-by: Andreea-Cristina Bernat Acked-by: Vasu Dev Signed-off-by: Christoph Hellwig

scsi: Fix up files implicitly depending on module.h inclusion

2011-10-31T23:31:24+00:00

The module.h header was implicitly present everywhere, so files with no explicit include of the module infrastructure would build anyway. We are now removing the implicit include, and so we need to call out the module.h file that we need explicitly. Signed-off-by: Paul Gortmaker

[SCSI] libfc: Extending lport's roles for target if there is a registered target.

2011-02-12T17:08:22+00:00

Problem: From initaitor machine, when queried role of target (other end of connection), it is "initiator", hence SCSI-ml doesn't send any LUN Inquiry commands. Fix: If there is a registered target for FC_TYPE_FCP, extend lport's params (capability) to be target as well, By default lport params are INITIATOR only. Having this fix, caused initiator to send SCSI LUN inquiry command to target. Signed-off-by: Kiran Patil Signed-off-by: Robert Love Signed-off-by: James Bottomley

[SCSI] libfc: add hook to notify providers of local port changes

2011-02-12T17:02:20+00:00

When an SCST provider is registered, it needs to know what local ports are available for configuration as targets. Add a notifier chain that is invoked when any local port that is added or deleted. Maintain a global list of local ports and add an interator function that calls a given function for every existing local port. This is used when first loading a provider.

[SCSI] libfc: add hook for FC-4 provider registration

2011-02-12T17:00:40+00:00

Allow FC-4 provider modules to hook into libfc, mostly for targets. This should allow any FC-4 module to handle PRLI requests and maintain process-association states. Each provider registers its ops with libfc and then will be called for any incoming PRLI for that FC-4 type on any instance. The provider can decide whether to handle that particular instance using any method it likes, such as ACLs or other configuration information. A count is kept of the number of successful PRLIs from the remote port. Providers are called back with an implicit PRLO when the remote port is about to be deleted or has been reset. fc_lport_recv_req() now sends incoming FC-4 requests to FC-4 providers, and there is a built-in provider always registered for handling incoming ELS requests. The call to provider recv() routines uses rcu_read_lock() so that providers aren't removed during the call. That lock is very cheap and shouldn't affect any performance on ELS requests. Providers can rely on the RCU lock to protect a session lookup as well. Signed-off-by: Joe Eykholt Signed-off-by: Robert Love Signed-off-by: James Bottomley
