rdma_nl_rcv_msg() checks to see if it should use the .dump() callback or the .doit() callback. The check is done with this check: if (flags & NLM_F_DUMP) ... The NLM_F_DUMP flag is two bits (NLM_F_ROOT | NLM_F_MATCH). When an RDMA_NL_LS message (response) is received, the bit used for indicating an error is the same bit as NLM_F_ROOT. NLM_F_ROOT == (0x100) == RDMA_NL_LS_F_ERR. ibacm sends a response with the RDMA_NL_LS_F_ERR bit set if an error occurs in the service. The current code then misinterprets the NLM_F_DUMP bit and trys to call the .dump() callback. If the .dump() callback for the specified request is not available (which is true for the RDMA_NL_LS messages) the following Oops occurs: [ 4555.960256] BUG: unable to handle kernel NULL pointer dereference at (null) [ 4555.969046] IP: (null) [ 4555.972664] PGD 10543f1067 P4D 10543f1067 PUD 1033f93067 PMD 0 [ 4555.979287] Oops: 0010 [#1] SMP [ 4555.982809] Modules linked in: rpcrdma ib_isert iscsi_target_mod target_core_mod ib_iser libiscsi scsi_transport_iscsi ib_ipoib rdma_ucm ib_ucm ib_uverbs ib_umad rdma_cm ib_cm iw_cm dm_mirror dm_region_hash dm_log dm_mod dax sb_edac x86_pkg_temp_thermal intel_powerclamp coretemp kvm irqbypass crct10dif_pclmul crc32_pclmul ghash_clmulni_intel pcbc aesni_intel crypto_simd glue_helper cryptd hfi1 rdmavt iTCO_wdt iTCO_vendor_support ib_core mei_me lpc_ich pcspkr mei ioatdma sg shpchp i2c_i801 mfd_core wmi ipmi_si ipmi_devintf ipmi_msghandler acpi_power_meter acpi_pad nfsd auth_rpcgss nfs_acl lockd grace sunrpc ip_tables ext4 mbcache jbd2 sd_mod mgag200 drm_kms_helper syscopyarea sysfillrect sysimgblt fb_sys_fops ttm igb ahci crc32c_intel ptp libahci pps_core drm dca libata i2c_algo_bit i2c_core [ 4556.061190] CPU: 54 PID: 9841 Comm: ibacm Tainted: G I 4.14.0-rc2+ #6 [ 4556.069667] Hardware name: Intel Corporation S2600WT2/S2600WT2, BIOS SE5C610.86B.01.01.0008.021120151325 02/11/2015 [ 4556.081339] task: ffff880855f42d00 task.stack: ffffc900246b4000 [ 4556.087967] RIP: 0010: (null) [ 4556.092166] RSP: 0018:ffffc900246b7bc8 EFLAGS: 00010246 [ 4556.098018] RAX: ffffffff81dbe9e0 RBX: ffff881058bb1000 RCX: 0000000000000000 [ 4556.105997] RDX: 0000000000001100 RSI: ffff881058bb1320 RDI: ffff881056362000 [ 4556.113984] RBP: ffffc900246b7bf8 R08: 0000000000000ec0 R09: 0000000000001100 [ 4556.121971] R10: ffff8810573a5000 R11: 0000000000000000 R12: ffff881056362000 [ 4556.129957] R13: 0000000000000ec0 R14: ffff881058bb1320 R15: 0000000000000ec0 [ 4556.137945] FS: 00007fe0ba5a38c0(0000) GS:ffff88105f080000(0000) knlGS:0000000000000000 [ 4556.147000] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 4556.153433] CR2: 0000000000000000 CR3: 0000001056f5d003 CR4: 00000000001606e0 [ 4556.161419] Call Trace: [ 4556.164167] ? netlink_dump+0x12c/0x290 [ 4556.168468] __netlink_dump_start+0x186/0x1f0 [ 4556.173357] rdma_nl_rcv_msg+0x193/0x1b0 [ib_core] [ 4556.178724] rdma_nl_rcv+0xdc/0x130 [ib_core] [ 4556.183604] netlink_unicast+0x181/0x240 [ 4556.187998] netlink_sendmsg+0x2c2/0x3b0 [ 4556.192392] sock_sendmsg+0x38/0x50 [ 4556.196299] SYSC_sendto+0x102/0x190 [ 4556.200308] ? __audit_syscall_entry+0xaf/0x100 [ 4556.205387] ? syscall_trace_enter+0x1d0/0x2b0 [ 4556.210366] ? __audit_syscall_exit+0x209/0x290 [ 4556.215442] SyS_sendto+0xe/0x10 [ 4556.219060] do_syscall_64+0x67/0x1b0 [ 4556.223165] entry_SYSCALL64_slow_path+0x25/0x25 [ 4556.228328] RIP: 0033:0x7fe0b9db2a63 [ 4556.232333] RSP: 002b:00007ffc55edc260 EFLAGS: 00000293 ORIG_RAX: 000000000000002c [ 4556.240808] RAX: ffffffffffffffda RBX: 0000000000000010 RCX: 00007fe0b9db2a63 [ 4556.248796] RDX: 0000000000000010 RSI: 00007ffc55edc280 RDI: 000000000000000d [ 4556.256782] RBP: 00007ffc55edc670 R08: 00007ffc55edc270 R09: 000000000000000c [ 4556.265321] R10: 0000000000000000 R11: 0000000000000293 R12: 00007ffc55edc280 [ 4556.273846] R13: 000000000260b400 R14: 000000000000000d R15: 0000000000000001 [ 4556.282368] Code: Bad RIP value.

Failure to tune PCIe capabilities should not fail driver load. This can cause the driver load to fail on systems with any of the following: 1. HFI's parent is not root. Example: HFI card is behind a PCIe bridge. 2. HFI's parent is not PCI Express capable. In these situations, failure to tune PCIe capabilities should be logged in the system message logs but not cause the driver load to fail. This patch also ensures pcie capability word DevCtl is written only after a successful read and the capability tuning process continues even if read/write of the pcie capability word DevCtl fails.

commit 9a9b8112 will cause core to fail UD QP from being destroyed on ipoib unload, therefore cause resources leakage. On pkey change event above patch modifies mgid before calling underlying driver to detach it from QP. Drivers' detach_mcast() will fail to find modified mgid it was never given to attach in a first place. Core qp->usecnt will never go down, so ib_destroy_qp() will fail. IPoIB driver actually does take care of new broadcast mgid based on new pkey by destroying an old mcast object in ipoib_mcast_dev_flush()) .... if (priv->broadcast) { rb_erase(&priv->broadcast->rb_node, &priv->multicast_tree); list_add_tail(&priv->broadcast->list, &remove_list); priv->broadcast = NULL; } ... then in restarted ipoib_macst_join_task() creating a new broadcast mcast object, sending join request and on completion tells the driver to attach to reinitialized QP: ... if (!priv->broadcast) { ... broadcast = ipoib_mcast_alloc(dev, 0); ... memcpy(broadcast->mcmember.mgid.raw, priv->dev->broadcast + 4, sizeof (union ib_gid)); priv->broadcast = broadcast; ...

The patch simplifies mlx5_ib_cont_pages and fixes the following issues in the original implementation: First issues is related to alignment of the PFNs. After the check base + p != PFN, the alignment of the PFN wasn't checked. So the PFN sequence 0, 1, 1, 2 would result in a page_shift of 13 even though the 3rd PFN is not 8KB aligned. This wasn't actually a bug because it was supported by all the existing mlx5 compatible device, but we don't want to require this support in all future devices. Another issue is because the inner loop didn't advance PFN so the test "if (base + p != pfn)" always failed for SGE with len > (1<<page_shift).

I ended up cherry-picking them as other changes had been made in Jarkko's branch after he sent me his original pull request. I plan on maintaining a separate branch for TPM (and other security subsystems) from now on. From Jarkko: 'Not much this time except a few fixes'" * 'next-tpm' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: tpm: ibmvtpm: simplify crq initialization and document crq format tpm: replace msleep() with usleep_range() in TPM 1.2/2.0 generic drivers Documentation: tpm: add powered-while-suspended binding documentation tpm: tpm_crb: constify acpi_device_id. tpm: vtpm: constify vio_device_id

The crq is passed in registers and is the same on BE and LE hosts. However, current implementation allocates a structure on-stack to represent the crq, initializes the members swapping them to BE, and loads the structure swapping it from BE. This is pointless and causes GCC warnings about ununitialized members. Get rid of the structure and the warnings.

The patch simply replaces all msleep function calls with usleep_range calls in the generic drivers. Tested with an Infineon TPM 1.2, using the generic tpm-tis module, for a thousand PCR extends, we see results going from 1m57s unpatched to 40s with the new patch. We obtain similar results when using the original and patched tpm_infineon driver, which is also part of the patch. Similarly with a STM TPM 2.0, using the CRB driver, it takes about 20ms per extend unpatched and around 7ms with the new patch. Note that the PCR consistency is untouched with this patch, each TPM has been tested with 10 million extends and the aggregated PCR value is continuously verified to be correct. As an extension of this work, this could potentially and easily be applied to other vendor's drivers. Still, these changes are not included in the proposed patch as they are untested.

For inline asm statements which have a CALL instruction, we list the stack pointer as a constraint to convince GCC to ensure the frame pointer is set up first: static inline void foo() { register void *__sp asm(_ASM_SP); asm("call bar" : "+r" (__sp)) } Unfortunately, that pattern causes Clang to corrupt the stack pointer. The fix is easy: convert the stack pointer register variable to a global variable. It should be noted that the end result is different based on the GCC version. With GCC 6.4, this patch has exactly the same result as before: defconfig defconfig-nofp distro distro-nofp before 9820389 9491555 8816046 8516940 after 9820389 9491555 8816046 8516940 With GCC 7.2, however, GCC's behavior has changed. It now changes its behavior based on the conversion of the register variable to a global. That somehow convinces it to *always* set up the frame pointer before inserting *any* inline asm. (Therefore, listing the variable as an output constraint is a no-op and is no longer necessary.) It's a bit overkill, but the performance impact should be negligible. And in fact, there's a nice improvement with frame pointers disabled: defconfig defconfig-nofp distro distro-nofp before 9796316 9468236 9076191 8790305 after 9796957 9464267 9076381 8785949 So in summary, while listing the stack pointer as an output constraint is no longer necessary for newer versions of GCC, it's still needed for older versions.
