xen/blkfront: limit allocated memory size to actual use case
Today the Xen blkfront driver allocates memory for one struct blkfront_ring_info for each communication ring. This structure is statically sized for the maximum supported configuration resulting in a size of more than 90 kB. As the main size contributor is one array inside the struct, the memory allocation can easily be limited by moving this array to be the last structure element and to allocate only the memory for the actually needed array size.

nbd: add a flush_workqueue in nbd_start_device
When kzalloc fail, may cause trying to destroy the
workqueue from inside the workqueue.
If num_connections is m (2 < m), and NO.1 ~ NO.n
(1 < n < m) kzalloc are successful. The NO.(n + 1)
failed. Then, nbd_start_device will return ENOMEM
to nbd_start_device_ioctl, and nbd_start_device_ioctl
will return immediately without running flush_workqueue.
However, we still have n recv threads. If nbd_release
run first, recv threads may have to drop the last
config_refs and try to destroy the workqueue from
inside the workqueue.
To fix it, add a flush_workqueue in nbd_start_device.
Fixes:

drbd: fifo_alloc() should use struct_size
Switching to struct_size for the allocation in fifo_alloc avoids hard-coding the type of fifo_buffer.values in fifo_alloc. It also provides overflow protection; to avoid pessimistic code being generated by the compiler as a result, this patch also switches fifo_size to unsigned, propagating the change as appropriate.

It has been a relatively quiet cycle for documentation, but there's still a
couple of things of note:
- Conversion of the NFS documentation to RST
- A new document on how to help with documentation (and a maintainer
profile entry too)
Plus the usual collection of typo fixes, etc.

y2038: core, driver and file system changes
These are updates to device drivers and file systems that for some reason or another were not included in the kernel in the previous y2038 series. I've gone through all users of time_t again to make sure the kernel is in a long-term maintainable state, replacing all remaining references to time_t with safe alternatives. Some related parts of the series were picked up into the nfsd, xfs, alsa and v4l2 trees. A final set of patches in linux-mm removes the now unused time_t/timeval/timespec types and helper functions after all five branches are merged for linux-5.6, ensuring that no new users get merged. As a result, linux-5.6, or my backport of the patches to 5.4 [1], should be the first release that can serve as a base for a 32-bit system designed to run beyond year 2038, with a few remaining caveats: - All user space must be compiled with a 64-bit time_t, which will be supported in the coming musl-1.2 and glibc-2.32 releases, along with installed kernel headers from linux-5.6 or higher. - Applications that use the system call interfaces directly need to be ported to use the time64 syscalls added in linux-5.1 in place of the existing system calls. This impacts most users of futex() and seccomp() as well as programming languages that have their own runtime environment not based on libc. - Applications that use a private copy of kernel uapi header files or their contents may need to update to the linux-5.6 version, in particular for sound/asound.h, xfs/xfs_fs.h, linux/input.h, linux/elfcore.h, linux/sockios.h, linux/timex.h and linux/can/bcm.h. - A few remaining interfaces cannot be changed to pass a 64-bit time_t in a compatible way, so they must be configured to use CLOCK_MONOTONIC times or (with a y2106 problem) unsigned 32-bit timestamps. Most importantly this impacts all users of 'struct input_event'. - All y2038 problems that are present on 64-bit machines also apply to 32-bit machines. In particular this affects file systems with on-disk timestamps using signed 32-bit seconds: ext4 with ext3-style small inodes, ext2, xfs (to be fixed soon) and ufs. Changes since v1 [2]: - Add Acks I received - Rebase to v5.5-rc1, dropping patches that got merged already - Add NFS, XFS and the final three patches from another series - Rewrite etnaviv patches - Add one late revert to avoid an etnaviv regression [1] https://git.kernel.org/pub/scm/linux/kernel/git/arnd/playground.git/log/?h=y2038-endgame [2] https://lore.kernel.org/lkml/20191108213257.3097633-1-arnd@arndb.de/ -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABCAAGBQJeMYy3AAoJEGCrR//JCVInEGwP/0R+S+ok7vw9OdLVT0lFl07D IcVabgOWf24imN7m7L7Mlt3nDfxIT4tMpiAXq7eMO3spcyViG18O2LXdSQ4/7QBp +BlhoMjOP9w34Jyd7mnkFr4vqQALvfIqkS8rFObDtDub2Rfj9PC36MRMIu8BPXlv RK8bigwJeH/DV38yc5/JeUcD+WuewYLsK9XPWN+4yB4vgGsNU3ZQQ6nnzbR3hMsN DN8WZ68Y7IBs0Kyxkf+s2zmRXtCa2RiFg/2TUsk5olVAJVaenvte69hq5RSbg1vW vLi6K8cBoPWL59nqCzcNE+TUhSUg3LOj/a/KWyl76yovz7AlJaNjssOf8ZjHw6sL MhQqz3hXTxiJDS2Jvbf1yojiYGlzrq/gqcRFGe9jPcZdieMc4/yZCx60G/Exa5Pu YdMcqMyDWPFyUAFQNWEF59HPheOdj6tb1KpJ6bwgCo3P7QqhLrU4z9w3Py4/ZfBO 4sWcWteSsD6MN/ADJ2WQ56nNxzM2AvkeVJKcF6FCkdngXX9T0GExmZz7SqB5Du99 9lNjIiD5E+LBa/Swo/7n49aYa8x06V1pmHYTZVh9Wkl+CZiO21umezQFrWsfaMTp xt3c6pFdMG5xNMGpreTAXOmf2R+T6O8IO2qQq/TYjzqOLH7QC830P7avkmml+cK1 LjOBE2TfSeO8Ru1dXV4t =wx0A -----END PGP SIGNATURE----- Merge tag 'y2038-drivers-for-v5.6-signed' of git://git.kernel.org:/pub/scm/linux/kernel/git/arnd/playground Pull y2038 updates from Arnd Bergmann: "Core, driver and file system changes These are updates to device drivers and file systems that for some reason or another were not included in the kernel in the previous y2038 series.

Merge branch 'work.openat2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull openat2 support from Al Viro:
"This is the openat2() series from Aleksa Sarai.
I'm afraid that the rest of namei stuff will have to wait - it got
zero review the last time I'd posted #work.namei, and there had been a
leak in the posted series I'd caught only last weekend. I was going to
repost it on Monday, but the window opened and the odds of getting any
review during that... Oh, well.
Anyway, openat2 part should be ready; that _did_ get sane amount of
review and public testing, so here it comes"
From Aleksa's description of the series:
"For a very long time, extending openat(2) with new features has been
incredibly frustrating. This stems from the fact that openat(2) is
possibly the most famous counter-example to the mantra "don't silently
accept garbage from userspace" -- it doesn't check whether unknown
flags are present[1].
This means that (generally) the addition of new flags to openat(2) has
been fraught with backwards-compatibility issues (O_TMPFILE has to be
defined as __O_TMPFILE|O_DIRECTORY|[O_RDWR or O_WRONLY] to ensure old
kernels gave errors, since it's insecure to silently ignore the
flag[2]). All new security-related flags therefore have a tough road
to being added to openat(2).
Furthermore, the need for some sort of control over VFS's path
resolution (to avoid malicious paths resulting in inadvertent
breakouts) has been a very long-standing desire of many userspace
applications.
This patchset is a revival of Al Viro's old AT_NO_JUMPS[3] patchset
(which was a variant of David Drysdale's O_BENEATH patchset[4] which
was a spin-off of the Capsicum project[5]) with a few additions and
changes made based on the previous discussion within [6] as well as
others I felt were useful.
In line with the conclusions of the original discussion of
AT_NO_JUMPS, the flag has been split up into separate flags. However,
instead of being an openat(2) flag it is provided through a new
syscall openat2(2) which provides several other improvements to the
openat(2) interface (see the patch description for more details). The
following new LOOKUP_* flags are added:
LOOKUP_NO_XDEV:
Blocks all mountpoint crossings (upwards, downwards, or through
absolute links). Absolute pathnames alone in openat(2) do not
trigger this. Magic-link traversal which implies a vfsmount jump is
also blocked (though magic-link jumps on the same vfsmount are
permitted).
LOOKUP_NO_MAGICLINKS:
Blocks resolution through /proc/$pid/fd-style links. This is done
by blocking the usage of nd_jump_link() during resolution in a
filesystem. The term "magic-links" is used to match with the only
reference to these links in Documentation/, but I'm happy to change
the name.
It should be noted that this is different to the scope of
~LOOKUP_FOLLOW in that it applies to all path components. However,
you can do openat2(NO_FOLLOW|NO_MAGICLINKS) on a magic-link and it
will *not* fail (assuming that no parent component was a
magic-link), and you will have an fd for the magic-link.
In order to correctly detect magic-links, the introduction of a new
LOOKUP_MAGICLINK_JUMPED state flag was required.
LOOKUP_BENEATH:
Disallows escapes to outside the starting dirfd's
tree, using techniques such as ".." or absolute links. Absolute
paths in openat(2) are also disallowed.
Conceptually this flag is to ensure you "stay below" a certain
point in the filesystem tree -- but this requires some additional
to protect against various races that would allow escape using
"..".
Currently LOOKUP_BENEATH implies LOOKUP_NO_MAGICLINKS, because it
can trivially beam you around the filesystem (breaking the
protection). In future, there might be similar safety checks done
as in LOOKUP_IN_ROOT, but that requires more discussion.
In addition, two new flags are added that expand on the above ideas:
LOOKUP_NO_SYMLINKS:
Does what it says on the tin. No symlink resolution is allowed at
all, including magic-links. Just as with LOOKUP_NO_MAGICLINKS this
can still be used with NOFOLLOW to open an fd for the symlink as
long as no parent path had a symlink component.
LOOKUP_IN_ROOT:
This is an extension of LOOKUP_BENEATH that, rather than blocking
attempts to move past the root, forces all such movements to be
scoped to the starting point. This provides chroot(2)-like
protection but without the cost of a chroot(2) for each filesystem
operation, as well as being safe against race attacks that
chroot(2) is not.
If a race is detected (as with LOOKUP_BENEATH) then an error is
generated, and similar to LOOKUP_BENEATH it is not permitted to
cross magic-links with LOOKUP_IN_ROOT.
The primary need for this is from container runtimes, which
currently need to do symlink scoping in userspace[7] when opening
paths in a potentially malicious container.
There is a long list of CVEs that could have bene mitigated by
having RESOLVE_THIS_ROOT (such as CVE-2017-1002101,
CVE-2017-1002102, CVE-2018-15664, and CVE-2019-5736, just to name a
few).
In order to make all of the above more usable, I'm working on
libpathrs[8] which is a C-friendly library for safe path resolution.
It features a userspace-emulated backend if the kernel doesn't support
openat2(2). Hopefully we can get userspace to switch to using it, and
thus get openat2(2) support for free once it's ready.
Future work would include implementing things like
RESOLVE_NO_AUTOMOUNT and possibly a RESOLVE_NO_REMOTE (to allow
programs to be sure they don't hit DoSes though stale NFS handles)"

core hierarchical irqdomain code.
- Fix a rare race condition while initializing the descriptor
array.
New drivers:
- Xylon LogiCVC GPIO driver.
- WDC934x GPIO controller driver.
Driver improvements:
- Implemented suspend/resume in the Tegra driver.
- MPC8xx edge detection fixup.
- Properly convert ThunderX to use hierarchical irqdomain
with GPIOLIB_IRQCHIP on top of the revert of the previous
buggy switchover. This time it works (hopefully).
Misc:
- Drop a FMC remnant file <linux/ipmi-fru.h>
- A slew of fixes.

Merge tag 'gpio-v5.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v5.6 kernel cycle.
This is a pretty calm cycle so far, nothing special going on really.
Some more changes will come in from the irqchip and pin control trees.
I also deleted an orphan include file for FMC that was dangling since
subsystem was removed.
Core changes:
- Document the usecases for the kernelspace vs userspace handling of
GPIOs.
- Handle MSI (message signalled interrupts) properly in the core
hierarchical irqdomain code.
- Fix a rare race condition while initializing the descriptor array.
New drivers:
- Xylon LogiCVC GPIO driver.
- WDC934x GPIO controller driver.
Driver improvements:
- Implemented suspend/resume in the Tegra driver.
- MPC8xx edge detection fixup.
- Properly convert ThunderX to use hierarchical irqdomain with
GPIOLIB_IRQCHIP on top of the revert of the previous buggy
switchover. This time it works (hopefully).
Misc:
- Drop a FMC remnant file <linux/ipmi-fru.h>
- A slew of fixes"

Merge branch 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity
Pull IMA updates from Mimi Zohar:
"Two new features - measuring certificates and querying IMA for a file
hash - and three bug fixes:
- Measuring certificates is like the rest of IMA, based on policy,
but requires loading a custom policy. Certificates loaded onto a
keyring, for example during early boot, before a custom policy has
been loaded, are queued and only processed after loading the custom
policy.
- IMA calculates and caches files hashes. Other kernel subsystems,
and possibly kernel modules, are interested in accessing these
cached file hashes.
The bug fixes prevent classifying a file short read (e.g. shutdown) as
an invalid file signature, add a missing blank when displaying the
securityfs policy rules containing LSM labels, and, lastly, fix the
handling of the IMA policy information for unknown LSM labels"
* 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity:
IMA: Defined delayed workqueue to free the queued keys
IMA: Call workqueue functions to measure queued keys

sound updates for 5.6-rc1
As diffstat shows we've had again a lot of works done for this cycle:
majority of changes are the continued componentization and code
refactoring in ASoC, the tree-wide PCM API updates and cleanups
and SOF updates while a few ASoC driver updates are seen, too.
Here we go, some highlights:
Core:
- Finally y2038 support landed to ALSA ABI;
some ioctls have been extended and lots of tricks were applied
- Applying the new managed PCM buffer API to all drivers;
the API itself was already merged in 5.5
- The already deprecated dimension support in ALSA control API is
dropped completely now
- Verification of ALSA control elements to catch API misuses
ASoC:
- Further code refactorings and moving things to the component level
- Lots of updates and improvements on SOF / Intel drivers;
now including common HDMI driver and SoundWire support
- New driver support for Ingenic JZ4770, Mediatek MT6660, Qualcomm
WCD934x and WSA881x, and Realtek RT700, RT711, RT715, RT1011, RT1015
and RT1308
HD-audio:
- Improved ring-buffer communications using waitqueue
- Drop the superfluous buffer preallocation on x86
Others:
- Many code cleanups, mostly constifications over the whole tree
- USB-audio: quirks for MOTU, Corsair Virtuoso, Line6 Helix
- FireWire: code refactoring for oxfw and dice drivers

Pull btrfs updates from David Sterba:
"Features, highlights:
- async discard
- "mount -o discard=async" to enable it
- freed extents are not discarded immediatelly, but grouped
together and trimmed later, with IO rate limiting
- the "sync" mode submits short extents that could have been
ignored completely by the device, for SATA prior to 3.1 the
requests are unqueued and have a big impact on performance
- the actual discard IO requests have been moved out of
transaction commit to a worker thread, improving commit latency
- IO rate and request size can be tuned by sysfs files, for now
enabled only with CONFIG_BTRFS_DEBUG as we might need to
add/delete the files and don't have a stable-ish ABI for
general use, defaults are conservative
- export device state info in sysfs, eg. missing, writeable
- no discard of extents known to be untouched on disk (eg. after
reservation)
- device stats reset is logged with process name and PID that called
the ioctl
Fixes:
- fix missing hole after hole punching and fsync when using NO_HOLES
- writeback: range cyclic mode could miss some dirty pages and lead
to OOM
- two more corner cases for metadata_uuid change after power loss
during the change
- fix infinite loop during fsync after mix of rename operations
Core changes:
- qgroup assign returns ENOTCONN when quotas not enabled, used to
return EINVAL that was confusing
- device closing does not need to allocate memory anymore
- snapshot aware code got removed, disabled for years due to
performance problems, reimplmentation will allow to select wheter
defrag breaks or does not break COW on shared extents
- tree-checker:
- check leaf chunk item size, cross check against number of
stripes
- verify location keys for DIR_ITEM, DIR_INDEX and XATTR items
- new self test for physical -> logical mapping code, used for super
block range exclusion
- assertion helpers/macros updated to avoid objtool "unreachable
code" reports on older compilers or config option combinations"
