This is not necessary, because we must already be soft-disabled in the interrupt context, it also may be causing crashes in the irq tracing code to re-enter as an nmi.

'perf annotate' displays annotated assembler output by reading output of command objdump and parsing the disassembled lines. For each shown mnemonic this function sequence is executed: disasm_line__new() | +--> disasm_line__init_ins() | +--> ins__find() | +--> arch->associate_instruction_ops() The s390x specific function assigned to function pointer associate_instruction_ops refers to function s390__associate_ins_ops(). This function checks for supported mnemonics and assigns a NULL pointer to unsupported mnemonics. However even the NULL pointer is added to the architecture dependend instruction array. This leads to an extremely large architecture instruction array (due to array resize logic in function arch__grow_instructions()). Depending on the objdump output being parsed the array can end up with several ten-thousand elements. This patch checks if a mnemonic is supported and only adds supported ones into the architecture instruction array. The array does not contain elements with NULL pointers anymore. Before the patch (With some debug printf output): [root@s35lp76 perf]# time ./perf annotate --stdio > /tmp/xxxbb real 8m49.679s user 7m13.008s sys 0m1.649s [root@s35lp76 perf]# fgrep '__ins__find sorted:1 nr_instructions:' /tmp/xxxbb | tail -1 __ins__find sorted:1 nr_instructions:87433 ins:0x341583c0 [root@s35lp76 perf]# The number of different s390x branch/jump/call/return instructions entered into the array is 87433.

For example the output of objdump produces (on x86): 23eee: 4c 8b 3d 13 01 21 00 mov 0x210113(%rip),%r15 # 234008 <stderr@@GLIBC_2.2.5+0x9a8> and the function mov__parse() is called to investigate the complete line. Mov__parse() breaks this line into several parts and finally calls function comment__symbol() to parse the data after the comment character '#'. Comment__symbol() expects a hexadecimal address followed by a symbol in '<' and '>' brackets. However the 2nd parameter given to function comment__symbol() always points to the comment character '#'. The address parsing always returns 0 because the character '#' is not a digit and strtoull() fails without being noticed. Fix this by advancing the second parameter to function comment__symbol() by one byte before invocation and add an error check after strtoull() has been called.

From: Lorenzo Colitti <lorenzo(a)google.com> [ Upstream commit be8f8284cd897af2482d4e54fbc2bdfc15557259 ] Currently it is possible to add or update socket policies, but not clear them. Therefore, once a socket policy has been applied, the socket cannot be used for unencrypted traffic. This patch allows (privileged) users to clear socket policies by passing in a NULL pointer and zero length argument to the {IP,IPV6}_{IPSEC,XFRM}_POLICY setsockopts. This results in both the incoming and outgoing policies being cleared. The simple approach taken in this patch cannot clear socket policies in only one direction. If desired this could be added in the future, for example by continuing to pass in a length of zero (which currently is guaranteed to return EMSGSIZE) and making the policy be a pointer to an integer that contains one of the XFRM_POLICY_{IN,OUT} enum values. An alternative would have been to interpret the length as a signed integer and use XFRM_POLICY_IN (i.e., 0) to clear the input policy and -XFRM_POLICY_OUT (i.e., -1) to clear the output policy.

The destroy operation will wait a rcu grace period and call qdisc_rcu_free(). At which point gso_cpu_skb is free'd along with all stats so no need to zero stats and gso_cpu_skb from the graft operation itself. Further after dropping the qdisc locks we can not continue to call qdisc_reset before waiting an rcu grace period so that the qdisc is detached from all cpus. By removing the qdisc_reset() here we get the correct property of waiting an rcu grace period and letting the qdisc_destroy operation clean up the qdisc correctly. Note, a refcnt greater than 1 would cause the destroy operation to be aborted however if this ever happened the reference to the qdisc would be lost and we would have a memory leak.

Right now, the default ->cmdfunc() implementations provided by the core do not filter out the command cycle in this case and forwards the request to the controller driver through the ->cmd_ctrl() method. The thing is, NAND controller drivers can get this wrong and send a command cycle with a NAND_CMD_NONE opcode and since NAND_CMD_NONE is -1, and the command field is usually casted to an u8, we end up sending the 0xFF command which is actually a RESET operation.

If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From foo@baz Fri Mar 16 15:43:16 CET 2018 From: Emmanuel Grumbach <emmanuel.grumbach(a)intel.com> Date: Thu, 19 Oct 2017 21:36:04 +0300 Subject: iwlwifi: mvm: rs: don't override the rate history in the search cycle From: Emmanuel Grumbach <emmanuel.grumbach(a)intel.com> [ Upstream commit 992172e3aec19e5b0ea5b757ba40a146b9282d1e ] When we are in a search cycle, we try different combinations of parameters. Those combinations are called 'columns'. When we switch to a new column, we first need to check if this column has a suitable rate, if not, we can't try it. This means we must not erase the statistics we gathered for the previous column until we are sure that we are indeed switching column. The code that tries to switch to a new column first sets a whole bunch of things for the new column, and only then checks that we can find suitable rates in that column. While doing that, the code mistakenly erased the rate statistics. This code was right until struct iwl_scale_tbl_info grew up for TPC. Fix this to make sure we don't erase the rate statistics until we are sure that we can indeed switch to the new column.

In that case the driver will detect a defective value and will try to reset the HW, assuming it is only a bus issue. The driver than proceeds with the dumping. The result has two side effects: 1. The device won't be stopped again, since the transport status is already stopped, so the device remains powered on while it actually should be stopped. 2. The dump in that case is completely garbaged and useless. Detect and avoid this. It will also make debugging such issues easier.

These files are normally created and only afterwards labeled, requiring them to be signed. Instead of requiring file signatures based on LSM labels, entire filesystems could require file signatures. In this case, we need the ability of writing new files without requiring file signatures. The definition of a "new" file was originally defined as any file with a length of zero. Subsequent patches redefined a "new" file to be based on the FILE_CREATE open flag. By combining the open flag with a file size of zero, this patch relaxes the file signature requirement.

If we fence_add_callback() on an array-fence, the array-fence's lock is acquired first, and in it's ->enable_signaling() callback, it will install cbs on it's array-member fences, so the array-member's lock is acquired second. But in the signal path, the array-member's lock is acquired first, and the array-fence's lock acquired second." Rob proposed either extensive changes to dma-fence to unnest the fence-array signaling, or to defer the signaling onto a workqueue. This is a more refined version of the later, that should keep the latency of the fence signaling to a minimum by using an irq-work, which is executed asap.

Prevent that from happening by acquiring an extra reference to the governor module temporarily in cpufreq_parse_governor(), under cpufreq_governor_mutex, and dropping it in store_scaling_governor(), when cpufreq_set_policy() returns. Note that the second cpufreq_parse_governor() call site is fine, because it only cares about the policy member of new_policy. Signed-off-by: Rafael J.

This information is useful for the target to perform some cleanups wrt the tdls peer.

Patch "arm64: dts: renesas: salvator-common: Add EthernetAVB PHY reset" has been added to the 4.14-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled arm64: dts: renesas: salvator-common: Add EthernetAVB PHY reset to the 4.14-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: arm64-dts-renesas-salvator-common-add-ethernetavb-phy-reset.patch and it can be found in the queue-4.14 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From foo@baz Fri Mar 16 15:43:17 CET 2018 From: Geert Uytterhoeven <geert+renesas(a)glider.be> Date: Mon, 4 Dec 2017 11:34:51 +0100 Subject: arm64: dts: renesas: salvator-common: Add EthernetAVB PHY reset From: Geert Uytterhoeven <geert+renesas(a)glider.be> [ Upstream commit f5bbcd533a9d1af97b8a0862a421bb8455f1bf6d ] Describe the GPIO used to reset the Ethernet PHY for EthernetAVB. This allows the driver to reset the PHY during probe and after system resume. This fixes Ethernet operation after resume from s2ram on Salvator-XS, where the enable pin of the regulator providing PHY power is connected to PRESETn, and PSCI powers down the SoC during system suspend.

In commit 3497971a71d8 ("agp/intel: Flush chipset writes after updating a single PTE"), we noticed corruption of the uploads for pwrite and for capturing GPU error states, but it was presumed that the explicit calls to intel_gtt_chipset_flush() were sufficient for the execbuffer path. However, we have not been flushing the chipset between the PTE writes and access via the GTT itself. For simplicity, do the flush after any PTE update rather than try and batch the flushes on a just-in-time basis.

The test was never about any security concerns and was always about how do we implement this for filesystems whose s_user_ns != &init_user_ns. At the moment this check makes no difference as there are no filesystems that both set FS_USERNS_MOUNT and implement d_automount. Remove this check now while I am thinking about it so there will not be odd booby traps for someone who does want to make this combination work. vfs_submount still needs improvements to allow this combination to work, and vfs_submount contains a check that presents a warning. The autofs4 filesystem could be modified to set FS_USERNS_MOUNT and it would need not work on this code path, as userspace performs the mounts.

However in some circumstances it is possible to see the hardware raise a GCRCSENT event before a TX_SUCCESS event is raised. The upshot of this is that the GCRCSENT handling portion of code ends up reporting the GoodCRC message to TCPM because the TX_SUCCESS event hasn't yet arrived to trigger a consumption of it. When TX_SUCCESS is then raised by the chip it ends up consuming the actual message that was meant for TCPM, and this incorrect sequence results in a hard reset from TCPM. To avoid this problem, this commit updates the message reading code to check whether a GoodCRC message was received or not. Based on this check it will either report that the previous transmission has completed or it will pass the msg data to TCPM for futher processing. This way the incorrect ordering of the events no longer matters.

The fw_filesystem.sh script creates a temporary directory to add a test firmware file to be used during testing, in order for this to work it uses the custom path syfs file and it was supposed to reset back the file on execution exit. The script failed to do this due to a typo, it was using OLD_PATH instead of OLD_FWPATH, since its inception since v3.17. Its not as easy to just keep the old setting, it turns out that resetting an empty setting won't actually do what we want, we need to check if it was empty and set an empty space.

But this doesn't work, as spi_bitbang_start() has to be called before requesting GPIOs because the GPIO data in the spi master is populated when the master is registed, and that doesn't happen until spi_bitbang_start() is called. The default only works if one uses one CS. So add a failure path call to spi_bitbang_stop() to fix the leak.

The driver's abort and request entry points currently is ignorant of the unloading state and is starting the requests even though the infrastructure to complete them continues to teardown. Change the entry points for new requests to check whether unloading and if so, reject the requests. Abort routines check unloading, and if so, noop the request.

But the CPU is offline, which presumably means that the task must be migrated to some other CPU, and that this other CPU will undertake any needed preemption at the time of migration. Because the runqueue lock is held when resched_curr() is invoked, we know that the boosted task cannot go anywhere, so it is not necessary to invoke resched_curr() in this particular case. This commit therefore makes switched_to_rt() refrain from invoking resched_curr() when the target CPU is offline. Signed-off-by: Paul E.

'perf annotate' displays annotated assembler output by reading output of command objdump and parsing the disassembled lines. For each shown mnemonic this function sequence is executed: disasm_line__new() | +--> disasm_line__init_ins() | +--> ins__find() | +--> arch->associate_instruction_ops() The s390x specific function assigned to function pointer associate_instruction_ops refers to function s390__associate_ins_ops(). This function checks for supported mnemonics and assigns a NULL pointer to unsupported mnemonics. However even the NULL pointer is added to the architecture dependend instruction array. This leads to an extremely large architecture instruction array (due to array resize logic in function arch__grow_instructions()). Depending on the objdump output being parsed the array can end up with several ten-thousand elements. This patch checks if a mnemonic is supported and only adds supported ones into the architecture instruction array. The array does not contain elements with NULL pointers anymore. Before the patch (With some debug printf output): [root@s35lp76 perf]# time ./perf annotate --stdio > /tmp/xxxbb real 8m49.679s user 7m13.008s sys 0m1.649s [root@s35lp76 perf]# fgrep '__ins__find sorted:1 nr_instructions:' /tmp/xxxbb | tail -1 __ins__find sorted:1 nr_instructions:87433 ins:0x341583c0 [root@s35lp76 perf]# The number of different s390x branch/jump/call/return instructions entered into the array is 87433.

For example the output of objdump produces (on x86): 23eee: 4c 8b 3d 13 01 21 00 mov 0x210113(%rip),%r15 # 234008 <stderr@@GLIBC_2.2.5+0x9a8> and the function mov__parse() is called to investigate the complete line. Mov__parse() breaks this line into several parts and finally calls function comment__symbol() to parse the data after the comment character '#'. Comment__symbol() expects a hexadecimal address followed by a symbol in '<' and '>' brackets. However the 2nd parameter given to function comment__symbol() always points to the comment character '#'. The address parsing always returns 0 because the character '#' is not a digit and strtoull() fails without being noticed. Fix this by advancing the second parameter to function comment__symbol() by one byte before invocation and add an error check after strtoull() has been called.

From: Lorenzo Colitti <lorenzo(a)google.com> [ Upstream commit be8f8284cd897af2482d4e54fbc2bdfc15557259 ] Currently it is possible to add or update socket policies, but not clear them. Therefore, once a socket policy has been applied, the socket cannot be used for unencrypted traffic. This patch allows (privileged) users to clear socket policies by passing in a NULL pointer and zero length argument to the {IP,IPV6}_{IPSEC,XFRM}_POLICY setsockopts. This results in both the incoming and outgoing policies being cleared. The simple approach taken in this patch cannot clear socket policies in only one direction. If desired this could be added in the future, for example by continuing to pass in a length of zero (which currently is guaranteed to return EMSGSIZE) and making the policy be a pointer to an integer that contains one of the XFRM_POLICY_{IN,OUT} enum values. An alternative would have been to interpret the length as a signed integer and use XFRM_POLICY_IN (i.e., 0) to clear the input policy and -XFRM_POLICY_OUT (i.e., -1) to clear the output policy.

The destroy operation will wait a rcu grace period and call qdisc_rcu_free(). At which point gso_cpu_skb is free'd along with all stats so no need to zero stats and gso_cpu_skb from the graft operation itself. Further after dropping the qdisc locks we can not continue to call qdisc_reset before waiting an rcu grace period so that the qdisc is detached from all cpus. By removing the qdisc_reset() here we get the correct property of waiting an rcu grace period and letting the qdisc_destroy operation clean up the qdisc correctly. Note, a refcnt greater than 1 would cause the destroy operation to be aborted however if this ever happened the reference to the qdisc would be lost and we would have a memory leak.
