From 9e8925b67a809bb27ce4b7d352d67f25cf1d7fc5 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Mon, 16 Nov 2015 09:49:34 -0500 Subject: locks: Allow disabling mandatory locking at compile time Mandatory locking appears to be almost unused and buggy and there appears no real interest in doing anything with it. Since effectively no one uses the code and since the code is buggy let's allow it to be disabled at compile time. I would just suggest removing the code but undoubtedly that will break some piece of userspace code somewhere. For the distributions that don't care about this piece of code this gives a nice starting point to make mandatory locking go away. Cc: Benjamin Coddington Cc: Dmitry Vyukov Cc: Jeff Layton Cc: J.

Additionally, by folding it in to arm_pmu_device_probe we can allow drivers to override struct pmu fields without getting blatted by the armpmu code. This patch folds armpmu_register into arm_pmu_device_probe. The logging to the console is moved to after the PMU is successfully registered with the core perf code.

include/media: split I2C headers from V4L2 core Currently, include/media is messy, as it contains both the V4L2 core headers and some driver-specific headers on the same place. That makes harder to identify what core headers should be documented and what headers belong to I2C drivers that are included only by bridge/main drivers that would require the functions provided by them. Let's move those i2c specific files to its own subdirectory. The files to move were produced via the following script: mkdir include/media/i2c (cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done) (cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/*/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done) for i in include/media/*.h; do n=`basename $i`; (for j in $(git grep -l $n); do dirname $j; done)|sort|uniq|grep -ve '^.$' > list; num=$(wc -l list|cut -d' ' -f1); if [ $num == 1 ]; then if [ "`grep i2c list`" != "" ]; then git mv $i include/media/i2c; fi; fi; done And the references corrected via this script: MAIN_DIR="media/" PREV_DIR="media/" DIRS="i2c/" echo "Checking affected files" >&2 for i in $DIRS; do for j in $(find include/$MAIN_DIR/$i -type f -name '*.h'); do n=`basename $j` git grep -l $n done done|sort|uniq >files && ( echo "Handling files..." >&2; echo "for i in \$(cat files|grep -v Documentation); do cat \$i | \\"; ( cd include/$MAIN_DIR; for j in $DIRS; do for i in $(ls $j); do echo "perl -ne 's,(include [\\\"\\<])$PREV_DIR($i)([\\\"\\>]),\1$MAIN_DIR$j\2\3,; print \$_' |\\"; done; done; echo "cat > a && mv a \$i; done"; ); echo "Handling documentation..." >&2; echo "for i in MAINTAINERS \$(cat files); do cat \$i | \\"; ( cd include/$MAIN_DIR; for j in $DIRS; do for i in $(ls $j); do echo " perl -ne 's,include/$PREV_DIR($i)\b,include/$MAIN_DIR$j\1,; print \$_' |\\"; done; done; echo "cat > a && mv a \$i; done" ); ) >script && . ./script Merged Sakari Ailus patch that moves smiapp.h to include/media/i2c.

The - selected tuner input, the selected SCART input and all I2S inputs go to - the DSP (the tuner input first goes through the demodulator). - - The DSP handles things like volume, bass/treble, balance, and some chips - have support for surround sound. It has several outputs: MAIN, AUX, I2S - and SCART1/2. Each output can select which DSP input to use. So the MAIN - output can select the tuner input while at the same time the SCART1 output - uses the I2S input. - - Outputs - ======= - - Most DSP outputs are also the outputs of the msp3400. However, the SCART - outputs of the msp3400 can select which input to use: either the SCART1 or - SCART2 output from the DSP, or the msp3400 SCART inputs, thus completely - bypassing the DSP. - - Summary - ======= - - So to specify a complete routing scheme for the msp3400 you will have to - specify in the 'input' arg of the s_routing function: - - 1) which tuner input to use - 2) which SCART input to use - 3) which DSP input to use for each DSP output - - And in the 'output' arg of the s_routing function you specify: - - 1) which SCART input to use for each SCART output - - Depending on how the msp is wired to the other components you can - ignore or mute certain inputs or outputs. - - Also, depending on the msp version only a subset of the inputs or - outputs may be present.

The uvcvideo driver only matches on bInterfaceProtocol 0, preventing those devices from being detected. More changes to the driver are needed for full UVC 1.5 compatibility. However, at least the UVC 1.5 Microsoft Surface Pro 3 cameras have been reported to work out of the box with the driver with an updated match table. Enable UVC 1.5 support in the match table to support the devices that can work with the current driver implementation.

All messages from the logging channel are timestamped and with that allow an easy correlation between userspace messages and hardware events. This will increase the ability to debug problems faster.

This patch adds cgroup->ancestor_ids[] which records the IDs of all ancestors including self and cgroup->level for the nesting level. This allows testing whether a given cgroup is a descendant of another in three finite steps - testing whether the two belong to the same hierarchy, whether the descendant candidate is at the same or a higher level than the ancestor and comparing the recorded ancestor_id at the matching level. cgroup_is_descendant() is accordingly reimplmented and made inline.

This makes it more useful, for example now you can alloc cpu_stop_work for stop_one_cpu_nowait() and free it in the callback or if stop_one_cpu_nowait() fails, currently this is impossible because you can't know if @fn will be called or not.

For callstack mode we don't need any of this information; so we can avoid the unnecessary MSR read. Add flags to the perf interface where perf record can request not collecting this information. Add branch_sample_type flags for CYCLES and FLAGS. It's a bit unusual for branch_sample_types to be negative (disable), not positive (enable), but since the legacy ABI reported the flags we need some form of explicit disabling to avoid breaking the ABI. After we have the flags the x86 perf code can keep track if any users need the flags. If noone needs it the information is not collected. This cuts down the cost of LBR callstack on Skylake significantly. Profiling a kernel build with LBR call stack the average run time of the PMI handler drops by 43%.

So rather than keeping the original skbs around just to discard them afterwards just use the original skbs directly for the fraglist of the newly assembled skb and remove the extra clone/free operations. The skb that completes the fragment queue is morphed into a the reassembled one instead, just like ipv4 defrag. openvswitch doesn't need any additional skb_morph magic anymore to deal with this situation so just remove that. A followup patch can then also remove the NF_HOOK (re)invocation in the ipv6 netfilter defrag hook.

McKenney" Date: Sun, 20 Sep 2015 17:03:16 -0700 Subject: list: Use READ_ONCE() when testing for empty lists Most of the list-empty-check macros (list_empty(), hlist_empty(), hlist_bl_empty(), hlist_nulls_empty(), and hlist_nulls_empty()) use an unadorned load to check the list header. Given that these macros are sometimes invoked without the protection of a lock, this is not sufficient. This commit therefore adds READ_ONCE() calls to them.

This is essential as modifying running code can be extremely dangerous to the system. When an anomaly is detected, ftrace_bug() is called which sends a splat to the console and disables function tracing. There's some extra information that is printed to help diagnose the issue. One thing that is missing though is output of what ftrace was doing at the time of the crash. Was it updating a call site or perhaps converting a call site to a nop? A new global enum variable is created to state what ftrace was doing at the time of the anomaly, and this is reported in ftrace_bug().

This gives an interface to underlying layers of the storage stack which can copy without reading and writing all the data. There are a few candidates that should support copy offloading in the nearer term: - btrfs shares extent references with its clone ioctl - NFS has patches to add a COPY command which copies on the server - SCSI has a family of XCOPY commands which copy in the device This system call avoids the complexity of also accelerating the creation of the destination file by operating on an existing destination file descriptor, not a path. Currently the high level vfs entry point limits copy offloading to files on the same mount and super (and not in the same file). This can be relaxed if we get implementations which can copy between file systems safely.

The same driver is used for both PFs and VFs; VFs are identified by the driver through the flag MLX5_PCI_DEV_IS_VF added to the pci table entries. Virtual functions are created as usual through writing a value to the sriov_numvs sysfs file of the PF device. Upon instantiating VFs, they will all be probed by the driver on the hypervisor. One can gracefully unbind them through /sys/bus/pci/drivers/mlx5_core/unbind. mlx5_wait_for_vf_pages() was added to ensure that when a VF dies without executing proper teardown, the hypervisor driver waits till all of the pages that were allocated at the hypervisor to maintain its operation are returned. In order for the VF to be operational, the PF needs to call enable_hca for it. This can be done before the VFs are created through a call to pci_enable_sriov. If the there are VFs assigned to a VMs when the driver of the PF is unloaded, all the VF will experience system error and PF driver unloads cleanly; in this case pci_disable_sriov is not called and the devices will show when running lspci. Once the PF driver is reloaded, it will sync its data structures which maintain state on its VFs. Signed-off-by: Eli Cohen Signed-off-by: Or Gerlitz Signed-off-by: David S.

E-Switch has its own Virtual Ports, each Vport/vNIC/VF can be connected to the device through a vport of an e-switch. Each e-switch is managed by one vNIC identified by HCA_CAP.vport_group_manager (usually it is the PF/vport[0]), and its main responsibility is to forward each packet to the right vport. e-Switch needs to manage its own l2-table and FDB tables. L2 table is a flow table that is managed by FW, it is needed for Multi-host (Multi PF) configuration for inter HCA switching between PFs. FDB table is a flow table that is totally managed by e-Switch driver, its main responsibility is to switch packets between e-Swtich internal vports and uplink vport that belong to the same. This patch introduces only e-Swtich l2 table management, FDB managemnt will come later when ethernet SRIOV/VFs will be enabled. preperation for ethernet sriov and l2 table management.

Create E-Switch FDB for L2 UC/MC mac steering between VFs/PF and external vport (Uplink). FDB contains forwarding rules such as: UC MAC0 -> vport0(PF). UC MAC1 -> vport1. UC MAC2 -> vport2. MC MACX -> vport0, vport2, Uplink. MC MACY -> vport1, Uplink. For unmatched traffic FDB has the following default rules: Unmached Traffic (src vport != Uplink) -> Uplink. Unmached Traffic (src vport == Uplink) -> vport0(PF). FDB rules population: Each NIC vport (VF) will notify E-Switch manager of its UC/MC vport context changes via modify vport context command, which will be translated to an event that will be handled by E-Switch manager (PF) which will update FDB table accordingly.

This commit therefore adds a rcu_normal kernel boot parameter (which can also be manipulated via sysfs) to suppress expedited grace periods, that is, to treat requests for expedited grace periods as if they were requests for normal grace periods. If both rcu_expedited and rcu_normal are specified, rcu_normal wins. This means that if you are relying on expedited grace periods to speed up boot, you will want to specify rcu_expedited on the kernel command line, and then specify rcu_normal via sysfs once boot completes.

Unfortunately this is difficult for some headers (such as x86 asm/msr.h) because including tracepoint.h includes so many other headers that it causes include loops. The main problem is the include of linux/rcupdate.h, which pulls in a lot of other headers. The rcu header is only needed when actually defining trace points. Move the struct tracepoint into a separate tracepoint-defs.h header that can be included without pulling in all of RCU.

When device nodes being passed, this is not true: the caller should pass its refcount to the component helper, and there should be a way to drop the refcount when the matching information is destroyed. This patch provides a per-match release method in addition to the match method to solve this issue. Rather than using component_match_add(), users should use component_match_add_release() which takes an additional function pointer for releasing this reference.

So, if a resource holds an index to a table, it may refer to different values during the lifetime of the resource, unless the tables are mirrored. Also, even when driver is not in HA mode the policy of allocating an index to these tables is such to make sure, as much as possible, that when the time comes the mirroring will be successful. This means that in multifunction mode the allocation of a free index in a port's table tries to make sure that the same index in the other's port table is also free.

It encompasses both the actual recvmsg code and a surrounding 'sleep until data is available' loop. This is inconvenient if a protocol module has to use additional locking in order to maintain some per-socket state the generic datagram socket code is unaware of (as the af_unix code does). The patch below moves the recvmsg proper code into a new __skb_try_recv_datagram routine which doesn't sleep and renames wait_for_more_packets to __skb_wait_for_more_packets, both routines being exported interfaces.

To avoid growth of various slightly incompatible implementations, add one to the VFS. Note that clones are different from file copies in several ways: - they are atomic vs other writers - they support whole file clones - they support 64-bit legth clones - they do not allow partial success (aka short writes) - clones are expected to be a fast metadata operation Because of that it would be rather cumbersome to try to piggyback them on top of the recent clone_file_range infrastructure. The converse isn't true and the clone_file_range system call could try clone file range as a first attempt to copy, something that further patches will enable. Based on earlier work from Peng Tao.

At resume time, such drivers rely on the core kernel irq subsystem to tell whether such or such interrupt is enabled or not, in order to restore the proper state in the interrupt controller register. While the irqd_irq_disabled() provides the relevant information for global interrupts, there is no similar function to query the enabled/disabled state of a per-CPU interrupt. Therefore, this commit complements the percpu_irq API with an irq_percpu_is_enabled() function.

One group of usage is from paths where the task may not be able to yield for a long time such as performing slow PIO to finicky device and coming out of suspend. The other is to account for scheduler and timer going idle. For scheduler softlockup detection, there's no reason to distinguish the two cases; however, workqueue lockup detector is planned and it can use the same signals from the former group while the latter would spuriously prevent detection. This patch introduces a new function touch_softlockup_watchdog_sched() and convert the latter group to call it instead. For now, it just calls touch_softlockup_watchdog() and there's no functional difference.

The array is allocated using kzalloc() effectively limiting the maximum ID supported to some thousand range. This patch caps the maximum supported css->id to USHRT_MAX which should be way above what is actually useable. This allows reducing sock->sk_cgrp_prioidx to u16 from u32. The freed up part will be used to overload the cgroup related fields. sock->sk_cgrp_prioidx's position is swapped with sk_mark so that the two cgroup related fields are adjacent.

As a result, cgroup v1 grew several controllers whose primary purpose is either tagging membership or pull in configuration knobs from other subsystems so that cgroup membership test can be avoided. net_cls and net_prio controllers are examples of the latter. They allow configuring network-specific attributes from cgroup side so that network subsystem can avoid testing cgroup membership; unfortunately, these are not only cumbersome but also problematic. Both net_cls and net_prio aren't properly hierarchical. Both inherit configuration from the parent on creation but there's no interaction afterwards. An ancestor doesn't restrict the behavior in its subtree in anyway and configuration changes aren't propagated downwards. Especially when combined with cgroup delegation, this is problematic because delegatees can mess up whatever network configuration implemented at the system level. net_prio would allow the delegatees to set whatever priority value regardless of CAP_NET_ADMIN and net_cls the same for classid. While it is possible to solve these issues from controller side by implementing hierarchical allowable ranges in both controllers, it would involve quite a bit of complexity in the controllers and further obfuscate network configuration as it becomes even more difficult to tell what's actually being configured looking from the network side. While not much can be done for v1 at this point, as membership handling is sane on cgroup v2, it'd be better to make cgroup matching behave like other network matches and classifiers than introducing further complications. In preparation, this patch updates sock->sk_cgrp_data handling so that it points to the v2 cgroup that sock was created in until either net_prio or net_cls is used. Once either of the two is used, sock->sk_cgrp_data reverts to its previous role of carrying prioidx and classid. This is to avoid adding yet another cgroup related field to struct sock. As the mode switching can happen at most once per boot, the switching mechanism is aimed at lowering hot path overhead. It may leak a finite, likely small, number of cgroup refs and report spurious prioidx or classid on switching; however, dynamic updates of prioidx and classid have always been racy and lossy - socks between creation and fd installation are never updated, config changes don't update existing sockets at all, and prioidx may index with dead and recycled cgroup IDs. Non-critical inaccuracies from small race windows won't make any noticeable difference. This patch doesn't make use of the pointer yet. The following patch will implement netfilter match for cgroup2 membership. v2: Use sock_cgroup_data to avoid inflating struct sock w/ another cgroup specific field. v3: Add comments explaining why sock_data_prioidx() and sock_data_classid() use different fallback values.

This way an RSA cipher with padding can be obtained by instantiating "pkcs1pad(rsa)". The reason for adding this is that RSA is almost never used without this padding (or OAEP) so it will be needed for either certificate work in the kernel or the userspace, and I also hear that it is likely implemented by hardware RSA in which case hardware implementations of the whole of pkcs1pad(rsa) can be provided.

Parts of LL/Network/Transport headers are provided as separate attributes. Otherwise, printing IP address data becomes virtually impossible for userspace since in the case of the netdev family we really don't want userspace to have to know all the possible link layer types and/or sizes just to display/print an ip address. We also don't want userspace to have to follow ipv6 header chains to get the s/dport info, the kernel already did this work for us. To avoid bloating nft_do_chain all data required for tracing is encapsulated in nft_traceinfo. The structure is initialized unconditionally(!) for each nft_do_chain invocation.

This way we also eliminate potential races with incoming mgmt commands or other actions while powering on. Part of this refactoring is the splitting of mgmt_powered() into mgmt_power_on() and __mgmt_power_off() functions. The main reason is the different requirements as far as hdev locking is concerned, as highlighted with the __ prefix of the power off API. Since the power on in the case of clearing the AUTO_OFF flag cannot be done synchronously in the set_powered mgmt handler, the hci_power_on work callback is extended to cover this (which also simplifies the set_powered helper a lot).

Commit 905e75c46dba ("powerpc/fsl-pci: Unify pci/pcie initialization code") turned the PCI controller code into a platform device. Since we can't have two drivers binding to the same device, the EDAC code was changed to be called into as a library-style submodule. However, this doesn't work if the EDAC driver is built as a module. Commit 8d8fcba6d1ea ("EDAC: Rip out the edac_subsys reference counting") exposed another problem with this approach -- mpc85xx_pci_err_probe() was being called in the same early boot phase that the PCI controller is initialized, rather than in the device_initcall phase that the EDAC layer expects. This caused a crash on boot. To fix this, the PCI controller code now creates a child platform device specifically for EDAC, which the mpc85xx-pci-edac driver binds to.

Looking at that code in more detail to fix the warnings, I see multiple related problems: * The conversion functions are not endian-safe, as the DMA descriptors are almost certainly fixed-endian, but the CPU is not. * On 64-bit machines, passing a pointer through a u32 variable is a bug, accessing an indirect pointer as a u32 pointer even more so. * The handling of epib and psdata mixes native-endian and device-endian data. In this patch, I try to sort out the types for most accesses here, adding le32_to_cpu/cpu_to_le32 where appropriate, and passing pointers through two 32-bit words in the descriptor padding, to make it plausible that the driver does the right thing if compiled for big-endian or 64-bit systems.

When there are a large number of directory entries, the likelihood of a collision goes up way too quickly. GFS2 will now return cookies that are guaranteed unique for a while, and then fail back to using 30 bits of filename hash. Specifically, the directory leaf blocks are divided up into chunks based on the minimum size of a gfs2 directory entry (48 bytes). Each entry's cookie is based off the chunk where it starts, in the linked list of leaf blocks that it hashes to (there are 131072 hash buckets). Directory entries will have unique names until they take reach chunk 8192. Assuming the largest filenames possible, and the least efficient spacing possible, this new method will still be able to return unique names when the previous method has statistically more than a 99% chance of a collision. The non-unique names it fails back to are guaranteed to not collide with the unique names. unique cookies will be in this format: - 1 bit "0" to make sure the the returned cookie is positive - 17 bits for the hash table index - 1 bit for the mode "0" - 13 bits for the offset non-unique cookies will be in this format: - 1 bit "0" to make sure the the returned cookie is positive - 17 bits for the hash table index - 1 bit for the mode "1" - 13 more bits of the name hash Another benefit of location based cookies, is that once a directory's exhash table is fully extended (so that multiple hash table indexs do not use the same leaf blocks), gfs2 can skip sorting the directory entries until it reaches the non-unique ones, and then it only needs to sort these. This provides a significant speed up for directory reads of very large directories. The only issue is that for these cookies to continue to point to the correct entry as files are added and removed from the directory, gfs2 must keep the entries at the same offset in the leaf block when they are split (see my previous patch). This means that until all the nodes in a cluster are running with code that will split the directory leaf blocks this way, none of the nodes can use the new cookie code. To deal with this, gfs2 now has the mount option loccookie, which, if set, will make it return these new location based cookies. This option must not be set until all nodes in the cluster are at least running this version of the kernel code, and you have guaranteed that there are no outstanding cookies required by other software, such as NFS. gfs2 uses some of the extra space at the end of the gfs2_dirent structure to store the calculated readdir cookies. This keeps us from needing to allocate a seperate array to hold these values. gfs2 recomputes the cookie stored in de_cookie for every readdir call. The time it takes to do so is small, and if gfs2 expected this value to be saved on disk, the new code wouldn't work correctly on filesystems created with an earlier version of gfs2. One issue with adding de_cookie to the union in the gfs2_dirent structure is that it caused the union to align itself to a 4 byte boundary, instead of its previous 2 byte boundary. This changed the offset of de_rahead. To solve that, I pulled de_rahead out of the union, since it does not need to be there.

Redirect output destination to console: no file redirection will be needed by an in-kernel debugger, there is even no file can be accessed when the debugger is running in the kernel mode. 2. Output command prompts: programs other than acpiexec can have different prompt characters and the prompt characters may be implemented as a special character sequence to form a char device IO protocol. 3. Command ready/complete handshake: OSPM debugger may wait more conditions to implement OSPM specific semantics (for example, FIFO full/empty conditions for O_NONBLOCK or IO open/close conditions). Leaving such OSPM specific stuffs in the ACPICA debugger core blocks Linux debugger IO driver implementation. Several new OSL APIs are provided by this patch: 1. acpi_os_initialize_command_signals: initialize command handshake mechanism or any other OSPM specific stuffs. 2. acpi_os_terminate_command_signals: reversal of acpi_os_initialize_command_signals. 3. acpi_os_wait_command_ready: putting debugger task into wait state when a command is not ready. OSPMs can terminate command loop by returning AE_CTRL_TERMINATE from this API. Normally, wait_event() or wait_for_multiple_object() may be used to implement this API. 4. acpi_os_notify_command_complete: putting user task into running state when a command has been completed. OSPMs can terminate command loop by returning AE_CTRL_TERMINATE from this API. Normally, wake_up() or set_event() may be used to implement this API. This patch also converts current command signaling implementation into a generic debugger layer (osgendbg.c) to be used by the existing OSPMs or acpiexec, in return, Linux can have chance to implement its own command handshake mechanism. This patch also implements acpiexec batch mode in a multi-threading mode comaptible style as a demo (this can be confirmed by configuring acpiexec into DEBUGGER_MULTI_THREADED mode where the batch mode is still working). Lv Zheng. Note that the OSPM specific command handshake mechanism is required by Linux kernel because: 1. Linux kernel trends to use wait queue to synchronize two threads, using mutexes to achieve that will cause false "dead lock" warnings. 2. The command handshake mechanism implemented by ACPICA is implemented in this way because of a design issue in debugger IO streaming. Debugger IO outputs are simply cached using a giant buffer, this should be tuned by Linux in the future. Signed-off-by: Lv Zheng Signed-off-by: Rafael J.

They actually will get executed in this situation.

The register is also used to enable FIQ. Since the platform will not boot unless this register is set up to "new with DCC" mode, we need a special quirk to be compiled-in for the RealView platforms. If we find the right compatible string on the GIC TestChip, we enable this quirk by looking up the system controller and enabling the special bits. We depend on the CONFIG_REALVIEW_DT Kconfig symbol as the old boardfile code has the same fix hardcoded, and this is only needed for the attempts to modernize the RealView code using device tree. After fixing this, the PB11MPCore boots with device tree only.

The variables of pf_retrans and max_retrans_path can be changed by the userspace application. Sometimes the user expects to disable pf state while the 2 variables are changed to enable pf state. So it is necessary to introduce a new variable to disable pf state. According to the suggestions from Vlad Yasevich, extra1 and extra2 are removed. The initialization of pf_enable is added.

The idea was that drivers would use the information from that struct to buffers suitable for the requested format. After the vb2 split series this pointer is now a void pointer, which is ugly, and the reality is that all existing drivers will effectively just look at the sizeimage field of v4l2_format. To make this more generic the queue_setup callback is changed: the void pointer is dropped, instead if the *num_planes argument is 0, then use the current format size, if it is non-zero, then it contains the number of requested planes and the sizes array contains the requested sizes. If either is unsupported, then return -EINVAL, otherwise use the requested size(s).

The q->plane_sizes array was global and it was overwritten by create_bufs. So if reqbufs was called with e.g. size 100000 then q->plane_sizes[0] would be set to 100000. If create_bufs was called afterwards with size 200000, then q->plane_sizes[0] would be overwritten with the new value. Calling create_bufs again for size 100000 would cause an error since 100000 is now less than q->plane_sizes[0]. This patch fixes this problem by 1) removing q->plane_sizes and using the vb->planes[].length field instead, and 2) by introducing a min_length field in struct vb2_plane. This field is set to the plane size as returned by the queue_setup op and is the minimum required plane size. So user pointers or dmabufs should all be at least this size.

This is intended as a default address generator mode for device types with no EUI64 implementation. The new generator is used for ARPHRD_NONE interfaces initially, adding default IPv6 autoconf support to e.g. tun interfaces. If the addrgenmode is set to 'random', either by default or manually, and no stable secret is available, then a random secret is used as input for the stable-privacy address generator. The secret can be read and modified like manually configured secrets, using the proc interface. Modifying the secret will change the addrgen mode to 'stable-privacy' to indicate that it operates on a known secret. Existing behaviour of the 'stable-privacy' mode is kept unchanged. If a known secret is available when the device is created, then the mode will default to 'stable-privacy' as before. The mode can be manually set to 'random' but it will behave exactly like 'stable-privacy' in this case. The secret will not change.

This effectively allow a process to have a "VRF-global" listen socket, with child sockets bound to the VRF device in which the packet originated. A similar behavior can be achieved using sk_mark, but a solution using marks is incomplete as it does not handle duplicate addresses in different L3 domains/VRFs.

In eBPF as in classic BPF, we have BPF_LD | BPF_ABS | BPF_{B,H,W} instructions that extract a byte, half-word or word out of the skb data though helpers such as bpf_load_pointer() (interpreter case). F.e. extracting a whole IPv6 address could possibly look like ... union v6addr { struct { __u32 p1; __u32 p2; __u32 p3; __u32 p4; }; __u8 addr[16]; }; [...] a.p1 = htonl(load_word(skb, off)); a.p2 = htonl(load_word(skb, off + 4)); a.p3 = htonl(load_word(skb, off + 8)); a.p4 = htonl(load_word(skb, off + 12)); [...] /* access to a.addr[...] */ This work adds a complementary helper bpf_skb_load_bytes() (we also have bpf_skb_store_bytes()) as an alternative where the same call would look like from an eBPF program: ret = bpf_skb_load_bytes(skb, off, addr, sizeof(addr)); Same verifier restrictions apply as in ffeedafbf023 ("bpf: introduce current->pid, tgid, uid, gid, comm accessors") case, where stack memory access needs to be statically verified and thus guaranteed to be initialized in first use (otherwise verifier cannot tell whether a subsequent access to it is valid or not as it's runtime dependent).

However, if such a CPU is infinitely looping in NMI context, we fail to save its register information into the crash dump. For example, this can happen when unknown NMIs are broadcast to all CPUs as follows: CPU 0 CPU 1 =========================== ========================== receive an unknown NMI unknown_nmi_error() panic() receive an unknown NMI spin_trylock(&panic_lock) unknown_nmi_error() crash_kexec() panic() spin_trylock(&panic_lock) panic_smp_self_stop() infinite loop kdump_nmi_shootdown_cpus() issue NMI IPI -----------> blocked until IRET infinite loop... Here, since CPU 1 is in NMI context, the second NMI from CPU 0 is blocked until CPU 1 executes IRET. However, CPU 1 never executes IRET, so the NMI is not handled and the callback function to save registers is never called. In practice, this can happen on some servers which broadcast NMIs to all CPUs when the NMI button is pushed. To save registers in this case, we need to: a) Return from NMI handler instead of looping infinitely or b) Call the callback function directly from the infinite loop Inherently, a) is risky because NMI is also used to prevent corrupted data from being propagated to devices. So, we chose b). This patch does the following: 1. Move the infinite looping of CPUs which haven't called panic() in NMI context (actually done by panic_smp_self_stop()) outside of panic() to enable us to refer pt_regs. Please note that panic_smp_self_stop() is still used for normal context. 2.

For example (x86 case): CPU 0: oops_end() crash_kexec() mutex_trylock() // acquired nmi_shootdown_cpus() // stop other CPUs CPU 1: panic() crash_kexec() mutex_trylock() // failed to acquire smp_send_stop() // stop other CPUs infinite loop If CPU 1 calls smp_send_stop() before nmi_shootdown_cpus(), kdump fails.

Supporting this bit adds new intermediate huge page sizes. The set of huge page sizes available depends on the base page size. Without using contiguous pages the huge page sizes are as follows. 4KB: 2MB 1GB 64KB: 512MB With a 4KB granule, the contiguous bit groups together sets of 16 pages and with a 64KB granule it groups sets of 32 pages. This enables two new huge page sizes in each case, so that the full set of available sizes is as follows. 4KB: 64KB 2MB 32MB 1GB 64KB: 2MB 512MB 16GB If a 16KB granule is used then the contiguous bit groups 128 pages at the PTE level and 32 pages at the PMD level. If the base page size is set to 64KB then 2MB pages are enabled by default. It is possible in the future to make 2MB the default huge page size for both 4KB and 64KB granules.

It uses something called the "control_ops" which is used to iterate over ops under it with the control_list_func(). The problem is that this control_ops and control_list_func unnecessarily complicates the code. By replacing FTRACE_OPS_FL_CONTROL with two new flags (FTRACE_OPS_FL_RCU and FTRACE_OPS_FL_PER_CPU) we can remove all the code that is special with the control ops and add the needed checks within the generic ftrace_list_func().

As creating the control causes a potential mutex inversion with the handler, creating the control will take the controls_rwsem under the dapm_mutex and accessing the control will take the dapm_mutex under controls_rwsem. All the users look like they want to be using the runtime class of the lock anyway, so this patch just changes snd_soc_dapm_mutex_lock to use the nested call, with the SND_SOC_DAPM_CLASS_RUNTIME class.

Currently these driver use this construct for this: if (acpi_video_get_backlight_type() == acpi_backlight_vendor) report_brightness_key_event(); This indirect way of detecting if acpi-video is active does not make the code easier to understand, and in some cases it is wrong because just because the preferred type != vendor does not mean that acpi-video is actually listening for brightness events, e.g. there may be no acpi-video bus on the system at all.

The _SUB method was found to be problematic for this interface because some implementations use control methods. Therefore, it is being removed. Operations cannot be used because this interface is called during the device discovery scan and the region handlers are not fully installed at that time.

This patch introduces support for binary attributes in a somewhat similar manner of sysfs binary attributes albeit with changes that fit the configfs usage model. Problems that configfs binary attributes fix are everything that requires a binary blob as part of the configuration of a resource, such as bitstream loading for FPGAs, DTBs for dynamically created devices etc. Look at Documentation/filesystems/configfs/configfs.txt for internals and howto use them.

However, that wasn't necessary, since the ACPI sleep support code in Linux can be modified to use the upstream ACPICA's API easily and the additional functions may be dropped which reduces the code size and puts the kernel's ACPICA code more in line with the upstream.

When a socket is bound to an address/port not yet in use and the reuseport flag has been set, the structure will be allocated and attached to the newly bound socket. When subsequent calls to bind are made for the same address/port, the shared structure will be updated to include the new socket and the newly bound socket will reference the group structure. Usually, when an incoming packet was destined for a reuseport group, all sockets in the same group needed to be considered before a dispatching decision was made. With this structure, an appropriate socket can be found after looking up just one socket in the group.

When selecting a socket for an incoming UDP packet, use the information available in sock_reuseport if present. This required adding an additional field to the UDP source address equality function to differentiate between exact and wildcard matches. The original use case allowed wildcard matches when checking for existing port uses during bind. The new use case of adding a socket to a reuseport group requires exact address matching. Performance test (using a machine with 2 CPU sockets and a total of 48 cores): Create reuseport groups of varying size. Use one socket from this group per user thread (pinning each thread to a different core) calling recvmmsg in a tight loop. Record number of messages received per second while saturating a 10G link. 10 sockets: 18% increase (~2.8M -> 3.3M pkts/s) 20 sockets: 14% increase (~2.9M -> 3.3M pkts/s) 40 sockets: 13% increase (~3.0M -> 3.4M pkts/s) This work is based off a similar implementation written by Ying Cai for implementing policy-based reuseport selection.

The new vma has a new pfnmap to the same pfn & cache type with VM_PAT set. Therefore, we only need to clear VM_PAT from the old vma in this case. Add untrack_pfn_moved(), which clears VM_PAT from a given old vma. move_vma() is changed to call this function with the old vma when VM_PFNMAP is set. move_vma() then calls do_munmap(), and untrack_pfn() is a no-op since VM_PAT is cleared.

Particularly, writing SR=0 seems to break read access for Spansion's s25fl064k. Unfortunately, we don't currently have a way to differentiate these Spansion and Winbond parts, so rather than regressing support for these Spansion flash, let's drop the new Winbond lock/unlock support for now. We can try to address Winbond support during the next release cycle.

We shouldn't export of_irq_count() to modules because it's an internal OF API that shouldn't be used by drivers. Platform drivers should use platform device APIs instead. Therefore, add a platform_irq_count() API that mirrors the of_irq_count() API so that platform drivers can stay DT agnostic.

This interface is similar to the GNTTABOP_copy hypercall ABI except the local buffers are provided using a virtual address (instead of a GFN and offset). To avoid userspace from having to page align its buffers the driver will use two or more ops if required. If the ioctl returns 0, the application must check the status of each segment with the segments status field. If the ioctl returns a -ve error code (EINVAL or EFAULT), the status of individual ops is undefined.

This is because ftrace_module_init() allocates pages to store the locations that ftrace hooks are placed in the module text. If do_init_module() fails, it still calls the MODULE_GOING notifiers which will tell ftrace to do a clean up of the pages it allocated for the module. But if load_module() fails before then, the pages allocated by ftrace_module_init() will never be freed. Call ftrace_release_mod() on the module if load_module() fails before getting to do_init_module().

In order to make the modifications of converting nops in the prologue of functions into callbacks, the text needs to be converted from read-only to read-write. When enabling function tracing, the text permission is updated, the functions are modified, and then they are put back. When loading a module, the updates to convert function calls to mcount is done before the module text is set to read-only. But after it is done, the module text is visible by the function tracer. Thus we have the following race: CPU 0 CPU 1 ----- ----- start function tracing set text to read-write load_module add functions to ftrace set module text read-only update all functions to callbacks modify module functions too < Can't it's read-only > When this happens, ftrace detects the issue and disables itself till the next reboot. To fix this, a new DISABLED flag is added for ftrace records, which all module functions get when they are added. Then later, after the module code is all set, the records will have the DISABLED flag cleared, and they will be enabled if any callback wants all functions to be traced. Note, this doesn't add the delay to later. It simply changes the ftrace_module_init() to do both the setting of DISABLED records, and then immediately calls the enable code. This helps with testing this new code as it has the same behavior as previously. Another change will come after this to have the ftrace_module_enable() called after the text is set to read-only.

The rationale behind that delay is to accommodate some PHYs that behave badly if their SStatus/ SControl registers are pounded immediately on resume. The Broadcom STB SATA PHY does not seem to have this issue. This patch introduces a new link flag that allows platforms to skip the debounce delay if it isn't needed.

If we don't already have that information cached, we may have to ask (and wait for) rpc.mountd. In both cases we currently hold the i_mutex on the parent of the directory we're asking rpc.mountd about. We've seen situations where rpc.mountd performs some operation on that directory that tries to take the i_mutex again, resulting in deadlock. With some care, we may be able to avoid that in rpc.mountd. But it seems better just to avoid holding a mutex while waiting on userspace. It appears that lookup_one_len is pretty much the only operation that needs the i_mutex. So we could just drop the i_mutex elsewhere and do something like mutex_lock() lookup_one_len() mutex_unlock() In many cases though the lookup would have been cached and not required the i_mutex, so it's more efficient to create a lookup_one_len() variant that only takes the i_mutex when necessary.

The clsact qdisc works on ingress, but also on egress. In both cases, it's execution happens without taking the qdisc lock, and the main difference for the egress part compared to prior version of [1] is that this can be applied with _any_ underlying real egress qdisc (also classless ones). Besides solving the use-case of [1], that is, allowing for more programmability on assigning skb->priority for the mqprio case that is supported by most popular 10G+ NICs, it also opens up a lot more flexibility for other tc applications. The main work on classification can already be done at clsact egress time if the use-case allows and state stored for later retrieval f.e. again in skb->priority with major/minors (which is checked by most classful qdiscs before consulting tc_classify()) and/or in other skb fields like skb->tc_index for some light-weight post-processing to get to the eventual classid in case of a classful qdisc. Another use case is that the clsact egress part allows to have a central egress counterpart to the ingress classifiers, so that classifiers can easily share state (e.g. in cls_bpf via eBPF maps) for ingress and egress. Currently, default setups like mq + pfifo_fast would require for this to use, for example, prio qdisc instead (to get a tc_classify() run) and to duplicate the egress classifier for each queue. With clsact, it allows for leaving the setup as is, it can additionally assign skb->priority to put the skb in one of pfifo_fast's bands and it can share state with maps. Moreover, we can access the skb's dst entry (f.e. to retrieve tclassid) w/o the need to perform a skb_dst_force() to hold on to it any longer. In lwt case, we can also use this facility to setup dst metadata via cls_bpf (bpf_skb_set_tunnel_key()) without needing a real egress qdisc just for that (case of IFF_NO_QUEUE devices, for example). The realization can be done without any changes to the scheduler core framework. All it takes is that we have two a-priori defined minors/child classes, where we can mux between ingress and egress classifier list (dev->ingress_cl_list and dev->egress_cl_list, latter stored close to dev->_tx to avoid extra cacheline miss for moderate loads). The egress part is a bit similar modelled to handle_ing() and patched to a noop in case the functionality is not used. Both handlers are now called sch_handle_ingress() and sch_handle_egress(), code sharing among the two doesn't seem practical as there are various minor differences in both paths, so that making them conditional in a single handler would rather slow things down. Full compatibility to ingress qdisc is provided as well. Since both piggyback on TC_H_CLSACT, only one of them (ingress/clsact) can exist per netdevice, and thus ingress qdisc specific behaviour can be retained for user space. This means, either a user does 'tc qdisc add dev foo ingress' and configures ingress qdisc as usual, or the 'tc qdisc add dev foo clsact' alternative, where both, ingress and egress classifier can be configured as in the below example. ingress qdisc supports attaching classifier to any minor number whereas clsact has two fixed minors for muxing between the lists, therefore to not break user space setups, they are better done as two separate qdiscs. I decided to extend the sch_ingress module with clsact functionality so that commonly used code can be reused, the module is being aliased with sch_clsact so that it can be auto-loaded properly. Alternative would have been to add a flag when initializing ingress to alter its behaviour plus aliasing to a different name (as it's more than just ingress). However, the first would end up, based on the flag, choosing the new/old behaviour by calling different function implementations to handle each anyway, the latter would require to register ingress qdisc once again under different alias. So, this really begs to provide a minimal, cleaner approach to have Qdisc_ops and Qdisc_class_ops by its own that share callbacks used by both. Example, adding qdisc: # tc qdisc add dev foo clsact # tc qdisc show dev foo qdisc mq 0: root qdisc pfifo_fast 0: parent :1 bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1 qdisc pfifo_fast 0: parent :2 bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1 qdisc pfifo_fast 0: parent :3 bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1 qdisc pfifo_fast 0: parent :4 bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1 qdisc clsact ffff: parent ffff:fff1 Adding filters (deleting, etc works analogous by specifying ingress/egress): # tc filter add dev foo ingress bpf da obj bar.o sec ingress # tc filter add dev foo egress bpf da obj bar.o sec egress # tc filter show dev foo ingress filter protocol all pref 49152 bpf filter protocol all pref 49152 bpf handle 0x1 bar.o:[ingress] direct-action # tc filter show dev foo egress filter protocol all pref 49152 bpf filter protocol all pref 49152 bpf handle 0x1 bar.o:[egress] direct-action A 'tc filter show dev foo' or 'tc filter show dev foo parent ffff:' will show an empty list for clsact. Either using the parent names (ingress/egress) or specifying the full major/minor will then show the related filter lists. Prior work on a mqprio prequeue() facility [1] was done mainly by John Fastabend.
