mm, slab/slub: introduce kmalloc-reclaimable caches
Kmem caches can be created with a SLAB_RECLAIM_ACCOUNT flag, which
indicates they contain objects which can be reclaimed under memory
pressure (typically through a shrinker). This makes the slab pages
accounted as NR_SLAB_RECLAIMABLE in vmstat, which is reflected also the
MemAvailable meminfo counter and in overcommit decisions. The slab pages
are also allocated with __GFP_RECLAIMABLE, which is good for
anti-fragmentation through grouping pages by mobility.
The generic kmalloc-X caches are created without this flag, but sometimes
are used also for objects that can be reclaimed, which due to varying size
cannot have a dedicated kmem cache with SLAB_RECLAIM_ACCOUNT flag. A
prominent example are dcache external names, which prompted the creation
of a new, manually managed vmstat counter NR_INDIRECTLY_RECLAIMABLE_BYTES

mm, slab: combine kmalloc_caches and kmalloc_dma_caches
Patch series "kmalloc-reclaimable caches", v4. As discussed at LSF/MM [1] here's a patchset that introduces kmalloc-reclaimable caches (more details in the second patch) and uses them for dcache external names. That allows us to repurpose the NR_INDIRECTLY_RECLAIMABLE_BYTES counter later in the series. With patch 3/6, dcache external names are allocated from kmalloc-rcl-* caches, eliminating the need for manual accounting. More importantly, it also ensures the reclaimable kmalloc allocations are grouped in pages separate from the regular kmalloc allocations. The need for proper accounting of dcache external names has shown it's easy for misbehaving process to allocate lots of them, causing premature OOMs. Without the added grouping, it's likely that a similar workload can interleave the dcache external names allocations with regular kmalloc allocations (note: I haven't searched myself for an example of such regular kmalloc allocation, but I would be very surprised if there wasn't some). A pathological case would be e.g. one 64byte regular allocations with 63 external dcache names in a page (64x64=4096), which means the page is not freed even after reclaiming after all dcache names, and the process can thus "steal" the whole page with single 64byte allocation. If other kmalloc users similar to dcache external names become identified, they can also benefit from the new functionality simply by adding __GFP_RECLAIMABLE to the kmalloc calls. Side benefits of the patchset (that could be also merged separately) include removed branch for detecting __GFP_DMA kmalloc(), and shortening kmalloc cache names in /proc/slabinfo output. The latter is potentially an ABI break in case there are tools parsing the names and expecting the values to be in bytes. This is how /proc/slabinfo looks like after booting in virtme: ... kmalloc-rcl-4M 0 0 4194304 1 1024 : tunables 1 1 0 : slabdata 0 0 0 ... kmalloc-rcl-96 7 32 128 32 1 : tunables 120 60 8 : slabdata 1 1 0 kmalloc-rcl-64 25 128 64 64 1 : tunables 120 60 8 : slabdata 2 2 0 kmalloc-rcl-32 0 0 32 124 1 : tunables 120 60 8 : slabdata 0 0 0 kmalloc-4M 0 0 4194304 1 1024 : tunables 1 1 0 : slabdata 0 0 0 kmalloc-2M 0 0 2097152 1 512 : tunables 1 1 0 : slabdata 0 0 0 kmalloc-1M 0 0 1048576 1 256 : tunables 1 1 0 : slabdata 0 0 0 ... /proc/vmstat with renamed nr_indirectly_reclaimable_bytes counter: ... nr_slab_reclaimable 2817 nr_slab_unreclaimable 1781 ... nr_kernel_misc_reclaimable 0 ... /proc/meminfo with new KReclaimable counter: ... Shmem: 564 kB KReclaimable: 11260 kB Slab: 18368 kB SReclaimable: 11260 kB SUnreclaim: 7108 kB KernelStack: 1248 kB ... This patch (of 6): The kmalloc caches currently mainain separate (optional) array kmalloc_dma_caches for __GFP_DMA allocations. There are tests for __GFP_DMA in the allocation hotpaths. We can avoid the branches by combining kmalloc_caches and kmalloc_dma_caches into a single two-dimensional array where the outer dimension is cache "type". This will also allow to add kmalloc-reclaimable caches as a third type.

mm: don't miss the last page because of round-off error
I've noticed, that dying memory cgroups are often pinned in memory by a single pagecache page. Even under moderate memory pressure they sometimes stayed in such state for a long time. That looked strange. My investigation showed that the problem is caused by applying the LRU pressure balancing math: scan = div64_u64(scan * fraction[lru], denominator), where denominator = fraction[anon] + fraction[file] + 1. Because fraction[lru] is always less than denominator, if the initial scan size is 1, the result is always 0. This means the last page is not scanned and has no chances to be reclaimed. Fix this by rounding up the result of the division. In practice this change significantly improves the speed of dying cgroups reclaim.

mm: rework memcg kernel stack accounting
If CONFIG_VMAP_STACK is set, kernel stacks are allocated using
__vmalloc_node_range() with __GFP_ACCOUNT. So kernel stack pages are
charged against corresponding memory cgroups on allocation and uncharged
on releasing them.
The problem is that we do cache kernel stacks in small per-cpu caches and
do reuse them for new tasks, which can belong to different memory cgroups.
Each stack page still holds a reference to the original cgroup, so the
cgroup can't be released until the vmap area is released.
To make this happen we need more than two subsequent exits without forks
in between on the current cpu, which makes it very unlikely to happen. As
a result, I saw a significant number of dying cgroups (in theory, up to 2
* number_of_cpu + number_of_tasks), which can't be released even by
significant memory pressure.
As a cgroup structure can take a significant amount of memory (first of
all, per-cpu data like memcg statistics), it leads to a noticeable waste
of memory.

include/linux/pfn_t.h: force '~' to be parsed as an unary operator
Tracing the event "fs_dax:dax_pmd_insert_mapping" with perf produces this
warning:
[fs_dax:dax_pmd_insert_mapping] unknown op '~'
It is printed in process_op (tools/lib/traceevent/event-parse.c) because
'~' is parsed as a binary operator.
perf reads the format of fs_dax:dax_pmd_insert_mapping ("print fmt") from
/sys/kernel/debug/tracing/events/fs_dax/dax_pmd_insert_mapping/format .
The format contains:
~(((u64) ~(~(((1UL) << 12)-1)))
^
\ interpreted as a binary operator by process_op().
This part is generated in the declaration of the event class
dax_pmd_insert_mapping_class in include/trace/events/fs_dax.h :
__print_flags_u64(__entry->pfn_val & PFN_FLAGS_MASK, "|",
PFN_FLAGS_TRACE),
This patch adds a pair of parentheses in the declaration of PFN_FLAGS_MASK
to make sure that '~' is parsed as a unary operator by perf.
The part of the format that was problematic is now:
~(((u64) (~(~(((1UL) << 12)-1))))
Now, all the '~' are parsed as unary operators.

Pull rdma updates from Jason Gunthorpe:
"This has been a smaller cycle with many of the commits being smallish
code fixes and improvements across the drivers.
- Driver updates for bnxt_re, cxgb4, hfi1, hns, mlx5, nes, qedr, and
rxe
- Memory window support in hns
- mlx5 user API 'flow mutate/steering' allows accessing the full
packet mangling and matching machinery from user space
- Support inter-working with verbs API calls in the 'devx' mlx5 user
API, and provide options to use devx with less privilege
- Modernize the use of syfs and the device interface to use attribute
groups and cdev properly for uverbs, and clean up some of the core
code's device list management
- More progress on net namespaces for RDMA devices
- Consolidate driver BAR mmapping support into core code helpers and
rework how RDMA holds poitners to mm_struct for get_user_pages
cases
- First pass to use 'dev_name' instead of ib_device->name
- Device renaming for RDMA devices"

sound updates for 4.20
There have been little changes in ALSA core stuff, but ASoC core still
kept rolling for the continued restructuring. The rest are lots of
small driver-specific changes and some minor API updates.
Here are highlights:
General:
- Appropriate fall-through annotations everywhere
- Some code cleanup in memalloc code, handling non-cacahed pages more
commonly in the helper
- Deployment of SNDRV_PCM_INFO_SYNC_APPLPTR flag consistently
Drivers:
- More HD-audio CA0132 codec improvement for supporting other Creative
boards
- Plumbing legacy HD-audio codecs as ASoC BE on Intel SST; this will
give move support of existing HD-audio devices with DSP
- A few device-specific HD-audio quirks as usual
- New quirk for RME CC devices and correction for B&W PX for USB-audio
- FireWire: code refactoring including devres usages
ASoC Core:
- Continued componentization works; it's almost done!
- A bunch of new for_each_foo macros
- Cleanups and fixes in DAPM code
ASoC Drivers:
- MCLK support for several different devices, including CS42L51, STM32
SAI, and MAX98373
- Support for Allwinner A64 CODEC analog, Intel boards with DA7219 and
MAX98927, Meson AXG PDM inputs, Nuvoton NAU8822, Renesas R8A7744 and
TI PCM3060

SCSI misc on 20181024
This is mostly updates of the usual drivers: UFS, esp_scsi, NCR5380, qla2xxx, lpfc, libsas, hisi_sas. In addition there's a set of mostly small updates to the target subsystem a set of conversions to the generic DMA API, which do have some potential for issues in the older drivers but we'll handle those as case by case fixes. A new myrs for the DAC960/mylex raid controllers to replace the block based DAC960 which is also being removed by Jens in this merge window. Plus the usual slew of trivial changes.

"The EDAC tree was busier than usual this cycle as the shortlog below
shows.
Also, this pull request is carrying an ACPI DSM driver which is used
to ask the platform to supply the DIMM location of a reported hardware
error and thus simplify all the EDAC logic when trying to map the
error address to the respective DIMM.

libnvdimm for 4.20
* Improve the efficiency and performance of reading nvdimm-namespace labels. Reduce the amount of label data read at driver load time by a few orders of magnitude. Reduce heavyweight call-outs to platform-firmware routines. * Handle media errors located in the 'struct page' array stored on a persistent memory namespace. Let the kernel clear these errors rather than an awkward userspace workaround. * Fix Address Range Scrub (ARS) completion tracking. Correct occasions where the kernel indicates completion of ARS before submission. * Fix asynchronous device registration reference counting. * Add support for reporting an nvdimm dirty-shutdown-count via sysfs. * Fix various small libnvdimm core and uapi issues. -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJb0NuwAAoJEB7SkWpmfYgCjUYP/1RK35zXBJSArGE3CUkap/zp exuqUzhisiE3RER13hNvC59AxXB9QuIbzuR5bzWm+Lawuuaozn3iL2oKn3Gy0inl yE3m/1Hx43FTkYdH86K9bpaXtRfymppJiR475jRFin17xWL3UP2JJgYtGwoRfO4p OL1aLcGo04Y1E2h6sVx97DjiwWN5uTaG9jCciZr2w+s5pg1seuEOJcAayp+6D0Tq i2hZvQ6nyxxF2WzGqRk3ABbRySpQ5o4b33I/jjOKEFwYoB8UiZQeLuL2WRr1ztfz jo+aalLJjZTOMgeWPIYSuV+U8vySVUwXpMhfrMGnIRm5BuE9JUlHrYkMLcLZJyei 2qgQ65mDmoViBVx0w5k2nUjP8Ju5lC7fZTaLU60vf+3FZvBbSTtmog2+P0xMLg17 AHebl9slzJPO4r/z4XY+n9Bk/qOz6sfWk07LugfNcMdeZriJKr7BUclZVZDYiPJA /Rtnd8XRu8hS5Kfj7wK2QD5sVklS5VQhho/zzBZHQcQkQBfRo6f6YQ83N/6yoTKD p6nel3uRMX2n8+EPyODYt9j0cF7JupWqlSpRKUORrdSz85gt4D6W578tkJCEOCm0 JOm5HdLlwIhlIcam/w0blLOr+a0sISS4cWR72Vc/lSZHoM8ouQiQC/lplpiAAWwI 7pSmlYEEbZRQCy6ZrlVy =0FtE -----END PGP SIGNATURE----- Merge tag 'libnvdimm-for-4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm Pull libnvdimm updates from Dan Williams: - Improve the efficiency and performance of reading nvdimm-namespace labels.

In this round, we've added 1) superblock checksum feature, 2) implemented new mount option which we can disable/enable checkpoint to provide atomic updates of entire filesystem, 3) refactored quota operations to enhance its consistency along with checkpoint, 4) fixed subtle IO hang conditions and roll-forward recovery flow to resurrect any fsync'ed inode metadata. Enhancement: - add checksum to keep superblock contents more safe - add checkpoint=disable/enable to support A/B update of entire filesystem - use plug for readahead IO in readdir - add more IO counts to avoid block layer hacks Bug fix: - prevent data corruption issue for hardware encryption - fix IO hang issues when GC is heavily triggered - add missing up_read in __write_node_page - recover inode metadata during roll-forward recovery flow - fix null pointer dereference issue in wrongly configured discard map There are some more sanity checks and minor bug fixes as well. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAlvPzt4ACgkQQBSofoJI UNJLfg/8Ch9TWfbeUEH+6ioJ4pdURHmb/gFOQRSGX8Nu+HkuPJQD8pqlheK7n5g7 Pw3K6NLXHmL2d8xSNFbBwYmUSAeoXTc0J4nqX0sUJ6m7SKsuQ45Qe3A90faKEoAA ce7flWKVI+aJcGurBe99GOM69ptfyjb1w/8UGB0pcXUDq4oaRv5a1UtAAm92WF7H 4/7jYD3ub5aeSynwe16wWR4B5aXJT0l0FcZYicI6IRY1mOjMtXuQt72AY+ffSzBt yQ6qb8OEl3xpfQZHHH00ZfvarkTBzXJGZwquiPX/CPzVcee8cOqPp+XZqN7CXBEr 9ItezxYiUxOkKCl12Al8DynHZa6o2kEnWxgd49WkL/cNdInnvf5MD0kdfCV3KfQa CAR0UVe2yTg5mGLemtTSWveLdHfI7+LhDmURuXmoTUa9GWldw0413qqVVypcsizv QOAS86hSicrVK+bDnCA70i8Xxw7YEnAyrfCcgihU84NZSi7nTPUYj4xtMd9SzRnK JO8gA79D7lcWaxUS4r9I+JBDwWcfMQZRPS7PFbvoGWilIwsEaocCPYNgtjCTsAsK 1fePqiF/265Q4lapmEhEjhuQSNH2xfJQZ4ux1OU+eS3OTDjbEAFBeVPZImh7Mo7F dkpXQwfcqAXPzOM4QAJ6hFX40D8SWMAlId6XGiIfJlrFmEUAxBk= =VDw4 -----END PGP SIGNATURE----- Merge tag 'f2fs-for-4.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "In this round, we've added 1) superblock checksum feature, 2) implemented new mount option which we can disable/enable checkpoint to provide atomic updates of entire filesystem, 3) refactored quota operations to enhance its consistency along with checkpoint, 4) fixed subtle IO hang conditions and roll-forward recovery flow to resurrect any fsync'ed inode metadata.

Pul xfs updates from Dave Chinner:
"There's not a huge amount of change in this cycle - Darrick has been
out of action for a couple of months (hence me sending the last few
pull requests), so we decided a quiet cycle mainly focussed on bug
fixes was a good idea. Darrick will take the helm again at the end of
this merge window.
FYI, I may be sending another update later in the cycle - there's a
pending rework of the clone/dedupe_file_range code that fixes numerous
bugs that is spread amongst the VFS, XFS and ocfs2 code. It has been
reviewed and tested, Al and I just need to work out the details of the
merge, so it may come from him rather than me.
Summary:
- only support filesystems with unwritten extents
- add definition for statfs XFS magic number
- remove unused parameters around reflink code
- more debug for dangling delalloc extents
- cancel COW extents on extent swap targets
- fix quota stats output and clean up the code
- refactor some of the attribute code in preparation for parent
pointers
- fix several buffer handling bugs"

Pull btrfs updates from David Sterba:
"This is the first batch with fixes and some nice performance
improvements.
Preliminary results show eg. more files/sec in fsmark, better perf on
multi-threaded workloads (filebench, dbench), fewer context switches
and overall better memory allocation characteristics (multiple
benchmarks).
Apart from general performance, there's an improvement for qgroups +
balance workload that's been troubling our users.
Note for stable: there are 20+ patches tagged for stable, out of 90.
Not all of them apply cleanly on all stable versions but the conflicts
are mostly due to simple cleanups and resolving should be obvious. The
fixes are otherwise independent.
Performance improvements:
- transition between blocking and spinning modes of path is gone,
which originally resulted to more unnecessary wakeups and updates
to the path locks, the effects are measurable and improve latency
and scalability
- qgroups: first batch of changes that should speedup balancing with
qgroups on, skip quota accounting on unchanged subtrees, overall
gain is about 30+% in runtime
- use rb-tree with cached first node for several structures, small
improvement to avoid pointer chasing
Fixes:
- trim
- fix: some blockgroups could have been missed if their logical
address was past the total filesystem size (ie. after a lot of
balancing)
- better error reporting, after processing blockgroups and whole
device
- fix: continue trimming block groups after an error is
encountered
- check for trim support of the device earlier and avoid some
unnecessary work
- less interaction with transaction commit that improves latency
on slower storage (eg. image files over NFS)
- fsync
- fix warning when replaying log after fsync of a O_TMPFILE
- fix wrong dentries after fsync of file that got its parent
replaced
- qgroups: fix rescan that might misc some dirty groups
- don't clean dirty pages during buffered writes, this could lead to
lost updates in some corner cases
- some block groups could have been delayed in creation, if the
allocation triggered another one
- error handling improvements
Cleanups:
- removed unused struct members and variables
- function return type cleanups
- delayed refs code refactoring
- protect against deadlock that could be caused by crafted image that
tries to allocate from a tree that's locked already"

Merge branch 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull siginfo updates from Eric Biederman: "I have been slowly sorting out siginfo and this is the culmination of that work. The primary result is in several ways the signal infrastructure has been made less error prone. The code has been updated so that manually specifying SEND_SIG_FORCED is never necessary. The conversion to the new siginfo sending functions is now complete, which makes it difficult to send a signal without filling in the proper siginfo fields. At the tail end of the patchset comes the optimization of decreasing the size of struct siginfo in the kernel from 128 bytes to about 48 bytes on 64bit. The fundamental observation that enables this is by definition none of the known ways to use struct siginfo uses the extra bytes. This comes at the cost of a small user space observable difference. For the rare case of siginfo being injected into the kernel only what can be copied into kernel_siginfo is delivered to the destination, the rest of the bytes are set to 0. For cases where the signal and the si_code are known this is safe, because we know those bytes are not used. For cases where the signal and si_code combination is unknown the bits that won't fit into struct kernel_siginfo are tested to verify they are zero, and the send fails if they are not. I made an extensive search through userspace code and I could not find anything that would break because of the above change. If it turns out I did break something it will take just the revert of a single change to restore kernel_siginfo to the same size as userspace siginfo. Testing did reveal dependencies on preferring the signo passed to sigqueueinfo over si->signo, so bit the bullet and added the complexity necessary to handle that case. Testing also revealed bad things can happen if a negative signal number is passed into the system calls. Something no sane application will do but something a malicious program or a fuzzer might do. So I have fixed the code that performs the bounds checks to ensure negative signal numbers are handled" * 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (80 commits) signal: Guard against negative signal numbers in copy_siginfo_from_user32 signal: Guard against negative signal numbers in copy_siginfo_from_user signal: In sigqueueinfo prefer sig not si_signo signal: Use a smaller struct siginfo in the kernel signal: Distinguish between kernel_siginfo and siginfo signal: Introduce copy_siginfo_from_user and use it's return value signal: Remove the need for __ARCH_SI_PREABLE_SIZE and SI_PAD_SIZE signal: Fail sigqueueinfo if si_signo != sig signal/sparc: Move EMT_TAGOVF into the generic siginfo.h signal/unicore32: Use force_sig_fault where appropriate signal/unicore32: Generate siginfo in ucs32_notify_die signal/unicore32: Use send_sig_fault where appropriate signal/arc: Use force_sig_fault where appropriate signal/arc: Push siginfo generation into unhandled_exception signal/ia64: Use force_sig_fault where appropriate signal/ia64: Use the force_sig(SIGSEGV,...) in ia64_rt_sigreturn signal/ia64: Use the generic force_sigsegv in setup_frame signal/arm/kvm: Use send_sig_mceerr signal/arm: Use send_sig_fault where appropriate signal/arm: Use force_sig_fault where appropriate ... |

tcp: add tcp_reset_xmit_timer() helper
With EDT model, SRTT no longer is inflated by pacing delays. This means that RTO and some other xmit timers might be setup incorrectly. This is particularly visible with either : - Very small enforced pacing rates (SO_MAX_PACING_RATE) - Reduced rto (from the default 200 ms) This can lead to TCP flows aborts in the worst case, or spurious retransmits in other cases. For example, this session gets far more throughput than the requested 80kbit : $ netperf -H 127.0.0.2 -l 100 -- -q 10000 MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 127.0.0.2 () port 0 AF_INET Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 540000 262144 262144 104.00 2.66 With the fix : $ netperf -H 127.0.0.2 -l 100 -- -q 10000 MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 127.0.0.2 () port 0 AF_INET Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 540000 262144 262144 104.00 0.12 EDT allows for better control of rtx timers, since TCP has a better idea of the earliest departure time of each skb in the rtx queue. We only have to eventually add to the timer the difference of the EDT time with current time. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net> |
