Pull SCSI target fixes from Nicholas Bellinger: "Mostly minor fixes this time around. The highlights include: - iscsi-target CHAP authentication fixes to enforce explicit key values (Tejas Vaykole + rahul.rane) - fix a long-standing OOPs in target-core when a alua configfs attribute is accessed after port symlink has been removed. (Sebastian Herbszt) - fix a v3.10.y iscsi-target regression causing the login reject status class/detail to be ignored (Christoph Vu-Brugier) - fix a v3.10.y iscsi-target regression to avoid rejecting an existing ITT during Data-Out when data-direction is wrong (Santosh Kulkarni + Arshad Hussain) - fix a iscsi-target related shutdown deadlock on UP kernels (Mikulas Patocka) - fix a v3.16-rc1 build issue with vhost-scsi + !CONFIG_NET (MST)" * git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: iscsi-target: fix iscsit_del_np deadlock on unload iovec: move memcpy_from/toiovecend to lib/iovec.c iscsi-target: Avoid rejecting incorrect ITT for Data-Out tcm_loop: Fix memory leak in tcm_loop_submission_work error path iscsi-target: Explicily clear login response PDU in exception path target: Fix left-over se_lun->lun_sep pointer OOPs iscsi-target; Enforce 1024 byte maximum for CHAP_C key value iscsi-target: Convert chap_server_compute_md5 to use kstrtoul

iovec: move memcpy_from/toiovecend to lib/iovec.c

ERROR: "memcpy_fromiovecend" [drivers/vhost/vhost_scsi.ko] undefined! commit 9f977ef7b671f6169eca78bf40f230fe84b7c7e5 vhost-scsi: Include prot_bytes into expected data transfer length in target-pending makes drivers/vhost/scsi.c call memcpy_fromiovecend(). This function is not available when CONFIG_NET is not enabled. socket.h already includes uio.h, so no callers need updating. Reported-by: Randy Dunlap Cc: Stephen Rothwell Cc: "David S.

lz4: fix another possible overrun

2014-06-27T18:21:07Z

There is one other possible overrun in the lz4 code as implemented by Linux at this point in time (which differs from the upstream lz4 codebase, but will get synced at in a future kernel release.) As pointed out by Don, we also need to check the overflow in the data itself. While we are at it, replace the odd error return value with just a "simple" -1 value as the return value is never used for anything other than a basic "did this work or not" check.

lz4: ensure length does not wrap

Given some pathologically compressed data, lz4 could possibly decide to wrap a few internal variables, causing unknown things to happen. Catch this before the wrapping happens and abort the decompression. Reported-by: "Don A. Bailey" Cc: stable Signed-off-by: Greg Kroah-Hartman

lzo: properly check for overruns

swiotlb: don't assume PA 0 is invalid

2014-06-20T20:04:32Z

In 2.6.29 io_tlb_orig_addr[] got converted from storing virtual addresses to storing physical ones. While checking virtual addresses against NULL is a legitimate thing to catch invalid entries, checking physical ones against zero isn't: There's no guarantee that PFN 0 is reserved on a particular platform. Since it is unclear whether the check in swiotlb_tbl_unmap_single() is actually needed, retain it but check against a guaranteed invalid physical address. This requires setting up the array in a suitable fashion. And since the original code failed to invalidate array entries when regions get unmapped, this is being fixed at once along with adding a similar check to swiotlb_tbl_sync_single(). Obviously the less intrusive change would be to simply drop the check in swiotlb_tbl_unmap_single(). Signed-off-by: Jan Beulich Signed-off-by: Konrad Rzeszutek Wilk
