commit aeb6641f upstream. gcc-6 complains about the indentation of the lpfc_destroy_vport_work_array() call in lpfc_online(), which clearly doesn't look right: drivers/scsi/lpfc/lpfc_init.c: In function 'lpfc_online': drivers/scsi/lpfc/lpfc_init.c:2880:3: warning: statement is indented as if it were guarded by... [-Wmisleading-indentation] lpfc_destroy_vport_work_array(phba, vports); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/scsi/lpfc/lpfc_init.c:2863:2: note: ...this 'if' clause, but it is not if (vports != NULL) ^~ Looking at the patch that introduced this code, it's clear that the behavior is correct and the indentation is wrong. This fixes the indentation and adds curly braces around the previous if() block for clarity, as that is most likely what caused the code to be misindented in the first place. Signed-off-by:

commit 7b0883f3 upstream. When converting period and duty_cycle from nanoseconds to fclk cycles, the error introduced by the integer division can be appreciable, especially in the case of slow fclk or short period. Use DIV_ROUND_CLOSEST_ULL() so that the error is kept to +/- 0.5 clock cycles. Fixes: 6604c655 ("pwm: Add PWM driver for OMAP using dual-mode timers") Signed-off-by:

commit cd378881 upstream. Add sanity checking to ensure that we do not program load or match values that are out of range if a user requests period or duty_cycle values which are not achievable. The match value cannot be less than the load value (but can be equal), and neither can be 0xffffffff. This means that there must be at least one fclk cycle between load and match, and another between match and overflow.

commit f8caa792 upstream. Fix the calculation of load_value and match_value. Currently they are slightly too low, which produces a noticeably wrong PWM rate with sufficiently short periods (i.e. when 1/period approaches clk_rate/2). Example: clk_rate=32768Hz, period=122070ns, duty_cycle=61035ns (8192Hz/50% PWM) Correct values: load = 0xfffffffc, match = 0xfffffffd Current values: load = 0xfffffffa, match = 0xfffffffc effective PWM: period=183105ns, duty_cycle=91553ns (5461Hz/50% PWM) Fixes: 6604c655 ("pwm: Add PWM driver for OMAP using dual-mode timers") Signed-off-by:

commit ec7957a6 upstream. Despite care take to allocate clocks state containers the SP810 driver actually just supports creating one instance: all clocks registered for every instance will end up with the exact same name and __clk_init() will fail. Rename the timclken<0> .. timclken<n> to sp810_<instance>_<n> so every clock on every instance gets a unique name. This is necessary for the RealView PBA8 which has two SP810 blocks: the second block will not register its clocks unless every clock on every instance is unique and results in boot logs like this: ------------[ cut here ]------------ WARNING: CPU: 0 PID: 0 at ../drivers/clk/versatile/clk-sp810.c:137 clk_sp810_of_setup+0x110/0x154() Modules linked in: CPU: 0 PID: 0 Comm: swapper/0 Not tainted 4.5.0-rc2-00030-g352718fc39f6-dirty #225 Hardware name: ARM RealView Machine (Device Tree Support) [<c00167f8>] (unwind_backtrace) from [<c0013204>] (show_stack+0x10/0x14) [<c0013204>] (show_stack) from [<c01a049c>] (dump_stack+0x84/0x9c) [<c01a049c>] (dump_stack) from [<c0024990>] (warn_slowpath_common+0x74/0xb0) [<c0024990>] (warn_slowpath_common) from [<c0024a68>] (warn_slowpath_null+0x1c/0x24) [<c0024a68>] (warn_slowpath_null) from [<c051eb44>] (clk_sp810_of_setup+0x110/0x154) [<c051eb44>] (clk_sp810_of_setup) from [<c051e3a4>] (of_clk_init+0x12c/0x1c8) [<c051e3a4>] (of_clk_init) from [<c0504714>] (time_init+0x20/0x2c) [<c0504714>] (time_init) from [<c0501b18>] (start_kernel+0x244/0x3c4) [<c0501b18>] (start_kernel) from [<7000807c>] (0x7000807c) ---[ end trace cb88537fdc8fa200 ]--- Cc: Michael Turquette <mturquette@baylibre.com> Cc: Pawel Moll <pawel.moll@arm.com> Fixes: 6e973d2c "clk: vexpress: Add separate SP810 driver" Signed-off-by:

commit 50359819 upstream. Commit e6d5e7d9 ("clk-divider: Fix READ_ONLY when divider > 1") removed the special ops struct for read-only clocks and instead opted to handle them inside the regular ops. On the rk3368 this results in breakage as aclkm now gets set a value. While it is the same divider value, the A53 core still doesn't like it, which can result in the cpu ending up in a hang. The reason being that "ACLKENMasserts one clock cycle before the rising edge of ACLKM" and the clock should only be touched when STANDBYWFIL2 is asserted. To fix this, reintroduce the read-only ops but do include the round_rate callback. That way no writes that may be unsafe are done to the divider register in any case. The Rockchip use of the clk_divider_ops is adapted to this split again, as is the nxp, lpc18xx-ccu driver that was included since the original commit. On lpc18xx-ccu the divider seems to always be read-only so only uses the new ops now. Fixes: e6d5e7d9 ("clk-divider: Fix READ_ONLY when divider > 1") Reported-by:

commit da6ccaaa upstream. Make the "Attempted send on closed socket" error messages generated in nbd_request_handler() ratelimited. When the nbd socket is shutdown, the nbd_request_handler() function emits an error message for every request remaining in its queue. If the queue is large, this will spam a large amount of messages to the log. There's no need for a separate error message for each request, so this patch ratelimits it. In the specific case this was found, the system was virtual and the error messages were logged to the serial port, which overwhelmed it.

commit f719e375 upstream. Jiri Bohac is reporting for a problem where the attempt to reschedule existing connection to another real server needs proper redirect for the conntrack used by the IPVS connection. For example, when IPVS connection is created to NAT-ed real server we alter the reply direction of conntrack. If we later decide to select different real server we can not alter again the conntrack. And if we expire the old connection, the new connection is left without conntrack. So, the only way to redirect both the IPVS connection and the Netfilter's conntrack is to drop the SYN packet that hits existing connection, to wait for the next jiffie to expire the old connection and its conntrack and to rely on client's retransmission to create new connection as usually. Jiri Bohac provided a fix that drops all SYNs on rescheduling, I extended his patch to do such drops only for connections that use conntrack. Here is the original report from Jiri Bohac: Since commit dc7b3eb9 ("ipvs: Fix reuse connection if real server is dead"), new connections to dead servers are redistributed immediately to new servers. The old connection is expired using ip_vs_conn_expire_now() which sets the connection timer to expire immediately. However, before the timer callback, ip_vs_conn_expire(), is run to clean the connection's conntrack entry, the new redistributed connection may already be established and its conntrack removed instead. Fix this by dropping the first packet of the new connection instead, like we do when the destination server is not available. The timer will have deleted the old conntrack entry long before the first packet of the new connection is retransmitted.

commit 7617a24f upstream. The IPVS SIP persistence engine is not able to parse the SIP header "Call-ID" when such header is inserted in the first positions of the SIP message. When IPVS is configured with "--pe sip" option, like for example: ipvsadm -A -u 1.2.3.4:5060 -s rr --pe sip -p 120 -o some particular messages (see below for details) do not create entries in the connection template table, which can be listed with: ipvsadm -Lcn --persistent-conn Problematic SIP messages are SIP responses having "Call-ID" header positioned just after message first line: SIP/2.0 200 OK [Call-ID header here] [rest of the headers] When "Call-ID" header is positioned down (after a few other headers) it is correctly recognized. This is due to the data offset used in get_callid function call inside ip_vs_pe_sip.c file: since dptr already points to the start of the SIP message, the value of dataoff should be initially 0. Otherwise the header is searched starting from some bytes after the first character of the SIP message. Fixes: 758ff033 ("IPVS: sip persistence engine") Signed-off-by:

commit 32cc92c7 upstream. For T4, kernel mode qps don't use the user doorbell. User mode qps during flow control db ringing are forced into kernel, where user doorbell is treated as kernel doorbell and proper bar2 offset in bar2 virtual space is calculated, which incase of T4 is a bogus address, causing a kernel panic due to illegal write during doorbell ringing. In case of T4, kernel mode qp bar2 virtual address should be 0. Added T4 check during bar2 virtual address calculation to return 0. Fixed Bar2 range checks based on bar2 physical address. The below oops will be fixed <1>BUG: unable to handle kernel paging request at 000000000002aa08 <1>IP: [<ffffffffa011d800>] c4iw_uld_control+0x4e0/0x880 [iw_cxgb4] <4>PGD 1416a8067 PUD 15bf35067 PMD 0 <4>Oops: 0002 [#1] SMP <4>last sysfs file: /sys/devices/pci0000:00/0000:00:03.0/0000:02:00.4/infiniband/cxgb4_0/node_guid <4>CPU 5 <4>Modules linked in: rdma_ucm rdma_cm ib_cm ib_sa ib_mad ib_uverbs ip6table_filter ip6_tables ebtable_nat ebtables ipt_MASQUERADE iptable_nat nf_nat nf_conntrack_ipv4 nf_defrag_ipv4 xt_state nf_conntrack ipt_REJECT xt_CHECKSUM iptable_mangle iptable_filter ip_tables bridge autofs4 target_core_iblock target_core_file target_core_pscsi target_core_mod configfs bnx2fc cnic uio fcoe libfcoe libfc scsi_transport_fc scsi_tgt 8021q garp stp llc cpufreq_ondemand acpi_cpufreq freq_table mperf vhost_net macvtap macvlan tun kvm uinput microcode iTCO_wdt iTCO_vendor_support sg joydev serio_raw i2c_i801 i2c_core lpc_ich mfd_core e1000e ptp pps_core ioatdma dca i7core_edac edac_core shpchp ext3 jbd mbcache sd_mod crc_t10dif pata_acpi ata_generic ata_piix iw_cxgb4 iw_cm ib_core ib_addr cxgb4 ipv6 dm_mirror dm_region_hash dm_log dm_mod [last unloaded: scsi_wait_scan] <4> Supermicro X8ST3/X8ST3 <4>RIP: 0010:[<ffffffffa011d800>] [<ffffffffa011d800>] c4iw_uld_control+0x4e0/0x880 [iw_cxgb4] <4>RSP: 0000:ffff880155a03db0 EFLAGS: 00010006 <4>RAX: 000000000000001d RBX: ffff88013ae5fc00 RCX: ffff880155adb180 <4>RDX: 000000000002aa00 RSI: 0000000000000001 RDI: ffff88013ae5fdf8 <4>RBP: ffff880155a03e10 R08: 0000000000000000 R09: 0000000000000001 <4>R10: 0000000000000000 R11: 0000000000000000 R12: 0000000000000000 <4>R13: 000000000000001d R14: ffff880156414ab0 R15: ffffe8ffffc05b88 <4>FS: 0000000000000000(0000) GS:ffff8800282a0000(0000) knlGS:0000000000000000 <4>CS: 0010 DS: 0018 ES: 0018 CR0: 000000008005003b <4>CR2: 000000000002aa08 CR3: 000000015bd0e000 CR4: 00000000000007e0 <4>DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 <4>DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 <4>Process cxgb4 (pid: 394, threadinfo ffff880155a00000, task ffff880156414ab0) <4>Stack: <4> ffff880156415068 ffff880155adb180 ffff880155a03df0 ffffffffa00a344b <4><d> 00000000000003e8 ffff880155920000 0000000000000004 ffff880155920000 <4><d> ffff88015592d438 ffffffffa00a3860 ffff880155a03fd8 ffffe8ffffc05b88 <4>Call Trace: <4> [<ffffffffa00a344b>] ? enable_txq_db+0x2b/0x80 [cxgb4] <4> [<ffffffffa00a3860>] ? process_db_full+0x0/0xa0 [cxgb4] <4> [<ffffffffa00a38a6>] process_db_full+0x46/0xa0 [cxgb4] <4> [<ffffffff8109fda0>] worker_thread+0x170/0x2a0 <4> [<ffffffff810a6aa0>] ? autoremove_wake_function+0x0/0x40 <4> [<ffffffff8109fc30>] ? worker_thread+0x0/0x2a0 <4> [<ffffffff810a660e>] kthread+0x9e/0xc0 <4> [<ffffffff8100c28a>] child_rip+0xa/0x20 <4> [<ffffffff810a6570>] ? kthread+0x0/0xc0 <4> [<ffffffff8100c280>] ? child_rip+0x0/0x20 <4>Code: e9 ba 00 00 00 66 0f 1f 44 00 00 44 8b 05 29 07 02 00 45 85 c0 0f 85 71 02 00 00 8b 83 70 01 00 00 45 0f b7 ed c1 e0 0f 44 09 e8 <89> 42 08 0f ae f8 66 c7 83 82 01 00 00 00 00 44 0f b7 ab dc 01 <1>RIP [<ffffffffa011d800>] c4iw_uld_control+0x4e0/0x880 [iw_cxgb4] <4> RSP <ffff880155a03db0> <4>CR2: 000000000002aa08` Based on original work by Bharat Potnuri <bharat@chelsio.com> Fixes: 74217d4c ("iw_cxgb4: support for bar2 qid densities exceeding the page size") Signed-off-by:

commit 16eeed7e upstream. Commit 0881841f introduced a regression by inverting a test check after calling clocksource_mmio_init(). That results on the system to hang at boot time. Fix it by inverting the test again. Fixes: 0881841f ("Replace code by clocksource_mmio_init") Reported-by:

commit c283e41e upstream. The DMA chip has a fixed number of requestor lines used for flow control. This number is platform dependent. The pxa_dma dma driver will use this value to activate or not the flow control. There won't be any impact on mmp_pdma driver. Signed-off-by:

commit 042d4460 upstream. The newly added STM code uses SRCU, but does not ensure that this code is part of the kernel: drivers/built-in.o: In function `stm_source_link_show': include/linux/srcu.h:221: undefined reference to `__srcu_read_lock' include/linux/srcu.h:238: undefined reference to `__srcu_read_unlock' drivers/built-in.o: In function `stm_source_link_drop': include/linux/srcu.h:221: undefined reference to `__srcu_read_lock' include/linux/srcu.h:238: undefined reference to `__srcu_read_unlock' This adds a Kconfig 'select' statement like all the other SRCU using drivers have.

commit c0b5eed1 upstream. It's better to set the continueSession attribute for the unseal operation so that the session object is not removed as a side-effect when the operation is successful. Since a user process created the session, it should be also decide when the session is destroyed. Signed-off-by:

commit f3c82ade upstream. In my original patch sealing with policy was done with dynamically allocated buffer that I changed later into an array so the checks in tpm2-cmd.c became invalid.

commit 3deb9438 upstream. gcc-6 found a dubious indentation in the megasas_mgmt_fw_ioctl function: drivers/scsi/megaraid/megaraid_sas_base.c: In function 'megasas_mgmt_fw_ioctl': drivers/scsi/megaraid/megaraid_sas_base.c:6658:4: warning: statement is indented as if it were guarded by...

This clarifies the code and avoids the warning by adding extra curly braces. Signed-off-by:

commit a6ab1e81 upstream. sunrpc_cache_pipe_upcall() can detect a race if CACHE_PENDING is no longer set. In this case it aborts the queuing of the upcall. However it has already taken a new counted reference on "h" and doesn't "put" it, even though it frees the data structure holding the reference. So let's delay the "cache_get" until we know we need it. Fixes: f9e1aedc ("sunrpc/cache: remove races with queuing an upcall.") Signed-off-by:
