2012-11-07target: pass sense_reason as a return valueChristoph Hellwig24-1059/+841
Pass the sense reason as an explicit return value from the I/O submission path instead of storing it in struct se_cmd and using negative return values. This cleans up a lot of the code pathes, and with the sparse annotations for the new sense_reason_t type allows for much better error checking. (nab: Convert spc_emulate_modesense + spc_emulate_modeselect to use sense_reason_t with Roland's MODE SELECT changes) Signed-off-by: Christoph Hellwig <hch@lst.de> Cc: Roland Dreier <roland@purestorage.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
2012-11-07target: Fix incorrect starting offset after MODE_SENSE refactoringNicholas Bellinger1-2/+5
This patch fixes a new off-by-one bug in the hardcoded starting offset of spc_emulate_modesense() code that causes BLOCK DESCRIPTOR to be incorrectly written within the MEDIUM TYPE buffer area of the mode parameter header. According to spc4r30, Section 7.5.4, BLOCK DESCRIPTOR for MODE_SENSE_10 starts at byte 3, and BLOCK_DESCRIPTOR for MODE_SENSE (6) starts at byte 2.

2012-11-07target: Add emulation for MODE SELECTRoland Dreier1-0/+53
This is another thing that compliance tests try, and it's easy to implement on top of the MODE SENSE refactoring; since we don't claim to support any changeable values, all we need to do is check that the page contents sent by the initiator match what we would return.

2012-11-07target: Implement mode page 0x1c, "Informational Exceptions"Roland Dreier1-0/+14
The Windows SCSI compliance test asks for this mode page, and it's easy to implement: we can just return all 0s to show we don't support any of these features. Signed-off-by: Roland Dreier <roland@purestorage.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
2012-11-07target: Refactor MODE SENSE emulationRoland Dreier1-59/+176
Convert spc_emulate_modesense() to use a table of mode pages, rather than a switch statement. This makes it possible to add more pages sanely -- in particular we no longer need to make sure we keep the 0x3f (return all mode pages) case in sync. While we're touching this code, make our MODE SENSE emulation a bit better in a couple of ways: - When the initiator passes PC == 1 asking for changeable values, return all 0s to show we don't support setting anything. - Return a block descriptor for disk devices.

2012-11-03l2tp: fix oops in l2tp_eth_create() error pathTom Parkin1-0/+1
When creating an L2TPv3 Ethernet session, if register_netdev() should fail for any reason (for example, automatic naming for "l2tpeth%d" interfaces hits the 32k-interface limit), the netdev is freed in the error path. However, the l2tp_eth_sess structure's dev pointer is left uncleared, and this results in l2tp_eth_delete() then attempting to unregister the same netdev later in the session teardown. This results in an oops. To avoid this, clear the session dev pointer in the error path. Signed-off-by: Tom Parkin <tparkin@katalix.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2012-11-02hashtable: introduce a small and naive hashtableSasha Levin1-0/+192
This hashtable implementation is using hlist buckets to provide a simple hashtable to prevent it from getting reimplemented all over the kernel. Signed-off-by: Sasha Levin <levinsasha928@gmail.com> [ Merging this now, so that subsystems can start applying Sasha's patches that use this - Linus ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2012-11-02frv: fix the broken preemptAl Viro1-20/+3
Just get %icc2 into the state we would have after local_irq_disable() and physical IRQ having happened since then. Then we can simply use preempt_schedule_irq() and be done with the whole mess. Acked-by: David Howells <dhowells@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2012-11-02FRV: Fix the new-style kernel_thread() stuffDavid Howells1-2/+3
The kernel_thread() changes for FRV don't work, and FRV fails to boot, starting with: commit 02ce496f152df87be081a64796498942c433a2fd Author: Al Viro <viro@zeniv.linux.org.uk> Date: Tue Sep 18 22:18:51 2012 -0400 Subject: frv: split ret_from_fork, simplify kernel_thread() a lot The problem is that the userspace registers are completely cleared when a kernel thread is created and all subsequent user threads are then copied from that. Unfortunately, however, the TBR and PSR registers are restored from the pt_regs and the values they should be set to are clobbered by the memset. Instead, copy across the old user registers as normal, and then merely alter GR8 and GR9 in it if we're going to execute a kernel thread. Signed-off-by: David Howells <dhowells@redhat.com>
2012-11-02FRV: Fix the preemption handlingDavid Howells1-1/+1
Fix the preemption handling in FRV code where the PREEMPT_ACTIVE value is incorrectly loaded into the threadinfo flags rather than the threadinfo preemption count. Unfortunately, the code cannot be simply converted to use preempt_schedule_irq() as is because FRV uses virtual interrupt disablement to cut down on the cost of actually disabling interrupts and thus local_irq_enable() doesn't actually enable interrupts.

2012-11-02FRV: gcc-4.1.2 also inlines weak functionsDavid Howells1-0/+2
gcc-4.1.2 inlines weak functions, which causes FRV to fail when the dummy thread_info_cache_init() gets inlined into start_kernel(). Signed-off-by: David Howells <dhowells@redhat.com>
2012-11-02FRV: Don't objcopy the GNU build_id noteDavid Howells1-4/+6
Don't let objcopy transfer the GNU build_id note into the loadable image as it is located at address 0 and the image ends up >3G in size. Signed-off-by: David Howells <dhowells@redhat.com>
