2012-10-07[SCSI] libfc: fix lun reset failure bugs in fc_fcp_resp handling of FCP_RSP_INFOYi Zou
In LUN RESET testing involving NetApp targets, it is observed that LUN RESET is failing. The fc_fcp_resp() is not completing the completion for the LUN RESET task since fc_fcp_resp assumes that the FCP_RSP_INFO is 8 bytes with the 4 byte reserved field, where in case of NetApp targets the FCP_RSP to LUN RESET only has 4 bytes of FCP_RSP_INFO. This leads fc_fcp_resp to error out w/o completing the task completion, eventually causing LUN RESET to be escalated to host reset, which is not very nice. Per FCP-3 r04, clause 9.5.15 and Table 23, the FCP_RSP_INFO field can be either 4 bytes or 8 bytes, with the last 4 bytes as "Reserved (if any)". Therefore it is valid to have 4 bytes FCP_RSP_INFO like some of the NetApp targets behave. Fixing this by validating the FCP_RSP_INFO against both the two spec allowed length.

2012-10-07[SCSI] fcoe: Fix write errors on NPIV portsNeerav Parikh
SCSI errors were generated while writing to LUNs connected via NPIV ports. Debugging this it was found that the FCoE packets transmitted via the NPIV ports were not tagged with correct user priority as negotiated with peer by DCB agent. This resulted in FCoE traffic going with priority zero(0) that did not have priority flow control (PFC) enabled for it. The initiator after transferring data to the target never saw any reply indicating the transfer was complete. This resulted in error recovery (ABTS) and SCSI command retries by the scsi-mid layer; eventually resulting in I/O errors. This patch fixes this issue by keeping the FCoE user priority information in the fcoe_interface instance that is common for both the physical port as well as NPIV ports connected to that physical port; instead of storing it in fcoe_port structure that has a per port instance.

A lot of stray ends got cleaned up and converted to saner primitives, disgusting mess in android/binder.c is still disgusting, but at least doesn't poke so much in descriptor table guts anymore. A bunch of relatively minor races got fixed in process, plus an ext4 struct file leak. - related thing - fget_light() partially unuglified; see fdget() in there (and yes, it generates the code as good as we used to have). - also related - bits of Cyrill's procfs stuff that got entangled into that work; _not_ all of it, just the initial move to fs/proc/fd.c and switch of fdinfo to seq_file. - Alex's fs/coredump.c spiltoff - the same story, had been easier to take that commit than mess with conflicts.

2012-10-02compat: fs: Generic compat_sys_sendfile implementationCatalin Marinas
This function is used by sparc, powerpc and arm64 for compat support. The patch adds a generic implementation which calls do_sendfile() directly and avoids set_fs(). The sparc architecture has wrappers for the sign extensions while powerpc relies on the compiler to do the this. The patch adds wrappers for powerpc to handle the u32->int type conversion. compat_sys_sendfile64() can be replaced by a sys_sendfile() call since compat_loff_t has the same size as off_t on a 64-bit system. On powerpc, the patch also changes the 64-bit sendfile call from sys_sendile64 to sys_sendfile. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Acked-by: David S.

2012-10-02fs: push rcu_barrier() from deactivate_locked_super() to filesystemsKirill A. Shutemov
There's no reason to call rcu_barrier() on every deactivate_locked_super(). We only need to make sure that all delayed rcu free inodes are flushed before we destroy related cache. Removing rcu_barrier() from deactivate_locked_super() affects some fast paths. E.g. on my machine exit_group() of a last process in IPC namespace takes 0.07538s. rcu_barrier() takes 0.05188s of that time. Signed-off-by: Kirill A.
