2015-11-28target: fix COMPARE_AND_WRITE non zero SGL offset data corruptionJan Engelhardt
target_core_sbc's compare_and_write functionality suffers from taking data at the wrong memory location when writing a CAW request to disk when a SGL offset is non-zero. This can happen with loopback and vhost-scsi fabric drivers when SCF_PASSTHROUGH_SG_TO_MEM_NOALLOC is used to map existing user-space SGL memory into COMPARE_AND_WRITE READ/WRITE payload buffers. Given the following sample LIO subtopology, % targetcli ls /loopback/ o- loopback ................................. [1 Target] o- naa.6001405ebb8df14a ....... [naa.60014059143ed2b3] o- luns ................................... [2 LUNs] o- lun0 ................ [iblock/ram0 (/dev/ram0)] o- lun1 ................

The page of the first entry of cmd->t_data_sg includes the CDB, and sg->offset is set to a position past the CDB. I presume that sg->offset is also the right choice to use for subsequent sglist members.

2015-11-28target: Fix race for SCF_COMPARE_AND_WRITE_POST checkingNicholas Bellinger
This patch addresses a race + use after free where the first stage of COMPARE_AND_WRITE in compare_and_write_callback() is rescheduled after the backend sends the secondary WRITE, resulting in second stage compare_and_write_post() callback completing in target_complete_ok_work() before the first can return. Because current code depends on checking se_cmd->se_cmd_flags after return from se_cmd->transport_complete_callback(), this results in first stage having SCF_COMPARE_AND_WRITE_POST set, which incorrectly falls through into second stage CAW processing code, eventually triggering a NULL pointer dereference due to use after free. To address this bug, pass in a new *post_ret parameter into se_cmd->transport_complete_callback(), and depend upon this value instead of ->se_cmd_flags to determine when to return or fall through into ->queue_status() code for CAW.

2015-11-28iscsi-target: Fix rx_login_comp hang after login failureNicholas Bellinger
This patch addresses a case where iscsi_target_do_tx_login_io() fails sending the last login response PDU, after the RX/TX threads have already been started. The case centers around iscsi_target_rx_thread() not invoking allow_signal(SIGINT) before the send_sig(SIGINT, ...) occurs from the failure path, resulting in RX thread hanging indefinately on iscsi_conn->rx_login_comp. Note this bug is a regression introduced by: commit e54198657b65625085834847ab6271087323ffea Author: Nicholas Bellinger <nab@linux-iscsi.org> Date: Wed Jul 22 23:14:19 2015 -0700 iscsi-target: Fix iscsit_start_kthreads failure OOPs To address this bug, complete ->rx_login_complete for good measure in the failure path, and immediately return from RX thread context if connection state did not actually reach full feature phase (TARG_CONN_STATE_LOGGED_IN).

2015-11-28ARM: 8454/1: OF implies OF_FLATTREEArnd Bergmann
On the ARM architecture, individual platforms select CONFIG_USE_OF if they need it, but all device tree code is keyed off CONFIG_OF. When building a platform without DT support and manually enabling CONFIG_OF, we now get a number of build errors, e.g. arch/arm/kernel/devtree.c: In function 'setup_machine_fdt': arch/arm/kernel/devtree.c:215:19: error: implicit declaration of function 'early_init_dt_verify' [-Werror=implicit-function-declaration] We could now try to separate the use case of booting from DT vs. the case of using the dynamic implementation, but that seems more complicated than it can gain us. This simply changes the ARM Kconfig file to always enable OF_RESERVED_MEM and OF_EARLY_FLATTREE when CONFIG_OF is enabled. These options add a little extra code when we just want the dynamic OF implementation, but that seems like a rather obscure case, and this version solves all CONFIG_OF related randconfig regressions.

2015-11-26xen/evtchn: dynamically grow pending event channel ringDavid Vrabel
If more than 1024 event channels are bound to a evtchn device then it possible (even with well behaved applications) for the ring to overflow and events to be lost (reported as an -EFBIG error). Dynamically increase the size of the ring so there is always enough space for all bound events. Well behaved applicables that only unmask events after draining them from the ring can thus no longer lose events. However, an application could unmask an event before draining it, allowing multiple entries per port to accumulate in the ring, and a overflow could still occur. So the overflow detection and reporting is retained. The ring size is initially only 64 entries so the common use case of an application only binding a few events will use less memory than before. The ring size may grow to 512 KiB (enough for all 2^17 possible channels). This order 7 kmalloc() may fail due to memory fragmentation, so we fall back to trying vmalloc().

2015-11-26xen/gntdev: Grant maps should not be subject to NUMA balancingBoris Ostrovsky
Doing so will cause the grant to be unmapped and then, during fault handling, the fault to be mistakenly treated as NUMA hint fault. In addition, even if those maps could partcipate in NUMA balancing, it wouldn't provide any benefit since we are unable to determine physical page's node (even if/when VNUMA is implemented). Marking grant maps' VMAs as VM_IO will exclude them from being part of NUMA balancing.

2015-11-26Revert "arm64: Mark kernel page ranges contiguous"Catalin Marinas
This reverts commit 348a65cdcbbf243073ee39d1f7d4413081ad7eab. Incorrect page table manipulation that does not respect the ARM ARM recommended break-before-make sequence may lead to TLB conflicts. The contiguous PTE patch makes the system even more susceptible to such errors by changing the mapping from a single page to a contiguous range of pages. An additional TLB invalidation would reduce the risk window, however, the correct fix is to switch to a temporary swapper_pg_dir. Once the correct workaround is done, the reverted commit will be re-applied. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Reported-by: Jeremy Linton <jeremy.linton@arm.com>
2015-11-26arm64: mm: keep reserved ASIDs in sync with mm after multiple rolloversWill Deacon
Under some unusual context-switching patterns, it is possible to end up with multiple threads from the same mm running concurrently with different ASIDs: 1. CPU x schedules task t with mm p containing ASID a and generation g This task doesn't block and the CPU doesn't context switch. So: * per_cpu(active_asid, x) = {g,a} * p->context.id = {g,a} 2. Some other CPU generates an ASID rollover. The global generation is now (g + 1). CPU x is still running t, with no context switch and so per_cpu(reserved_asid, x) = {g,a} 3. CPU y schedules task t', which shares mm p with t. The generation mismatches, so we take the slowpath and hit the reserved ASID from CPU x. p is then updated so that p->context.id = {g + 1,a} 4. CPU y schedules some other task u, which has an mm != p. 5. Some other CPU generates *another* CPU rollover. The global generation is now (g + 2). CPU x is still running t, with no context switch and so per_cpu(reserved_asid, x) = {g,a}. 6. CPU y once again schedules task t', but now *fails* to hit the reserved ASID from CPU x because of the generation mismatch. This results in a new ASID being allocated, despite the fact that t is still running on CPU x with the same mm. Consequently, TLBIs (e.g. as a result of CoW) will not be synchronised between the two threads. This patch fixes the problem by updating all of the matching reserved ASIDs when we hit on the slowpath (i.e. in step 3 above). This keeps the reserved ASIDs in-sync with the mm and avoids the problem.
