Merge tag 'ceph-for-5.11-rc1' of git://github.com/ceph/ceph-client
Pull ceph updates from Ilya Dryomov:
"The big ticket item here is support for msgr2 on-wire protocol, which
adds the option of full in-transit encryption using AES-GCM algorithm
(myself).
On top of that we have a series to avoid intermittent errors during
recovery with recover_session=clean and some MDS request encoding work
from Jeff, a cap handling fix and assorted observability improvements
from Luis and Xiubo and a good number of cleanups.
Luis also ran into a corner case with quotas which sadly means that we
are back to denying cross-quota-realm renames"

Merge tag 'ovl-update-5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs
Pull overlayfs updates from Miklos Szeredi: - Allow unprivileged mounting in a user namespace. For quite some time the security model of overlayfs has been that operations on underlying layers shall be performed with the privileges of the mounting task. This way an unprvileged user cannot gain privileges by the act of mounting an overlayfs instance. A full audit of all function calls made by the overlayfs code has been performed to see whether they conform to this model, and this branch contains some fixes in this regard. - Support running on copied filesystem images by optionally disabling UUID verification. - Bug fixes as well as documentation updates. * tag 'ovl-update-5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs: ovl: unprivieged mounts ovl: do not get metacopy for userxattr ovl: do not fail because of O_NOATIME ovl: do not fail when setting origin xattr ovl: user xattr ovl: simplify file splice ovl: make ioctl() safe ovl: check privs before decoding file handle vfs: verify source area in vfs_dedupe_file_range_one() vfs: move cap_convert_nscap() call into vfs_setxattr() ovl: fix incorrect extent info in metacopy case ovl: expand warning in ovl_d_real() ovl: document lower modification caveats ovl: warn about orphan metacopy ovl: doc clarification ovl: introduce new "uuid=off" option for inodes index feature ovl: propagate ovl_fs to ovl_decode_real_fh and ovl_encode_real_fh |

Merge tag 'f2fs-for-5.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim: "In this round, we've made more work into per-file compression support. For example, F2FS_IOC_GET | SET_COMPRESS_OPTION provides a way to change the algorithm or cluster size per file. F2FS_IOC_COMPRESS | DECOMPRESS_FILE provides a way to compress and decompress the existing normal files manually. There is also a new mount option, compress_mode=fs|user, which can control who compresses the data. Chao also added a checksum feature with a mount option so that we are able to detect any corrupted cluster. In addition, Daniel contributed casefolding with encryption patch, which will be used for Android devices. Summary: Enhancements: - add ioctls and mount option to manage per-file compression feature - support casefolding with encryption - support checksum for compressed cluster - avoid IO starvation by replacing mutex with rwsem - add sysfs, max_io_bytes, to control max bio size Bug fixes: - fix use-after-free issue when compression and fsverity are enabled - fix consistency corruption during fault injection test - fix data offset for lseek - get rid of buffer_head which has 32bits limit in fiemap - fix some bugs in multi-partitions support - fix nat entry count calculation in shrinker - fix some stat information And, we've refactored some logics and fix minor bugs as well" * tag 'f2fs-for-5.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (36 commits) f2fs: compress: fix compression chksum f2fs: fix shift-out-of-bounds in sanity_check_raw_super() f2fs: fix race of pending_pages in decompression f2fs: fix to account inline xattr correctly during recovery f2fs: inline: fix wrong inline inode stat f2fs: inline: correct comment in f2fs_recover_inline_data f2fs: don't check PAGE_SIZE again in sanity_check_raw_super() f2fs: convert to F2FS_*_INO macro f2fs: introduce max_io_bytes, a sysfs entry, to limit bio size f2fs: don't allow any writes on readonly mount f2fs: avoid race condition for shrinker count f2fs: add F2FS_IOC_DECOMPRESS_FILE and F2FS_IOC_COMPRESS_FILE f2fs: add compress_mode mount option f2fs: Remove unnecessary unlikely() f2fs: init dirty_secmap incorrectly f2fs: remove buffer_head which has 32bits limit f2fs: fix wrong block count instead of bytes f2fs: use new conversion functions between blks and bytes f2fs: rename logical_to_blk and blk_to_logical f2fs: fix kbytes written stat for multi-device case ... |

Merge tag 'pinctrl-v5.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control updates from Linus Walleij:
"This is the bulk of pin control changes for the v5.11 kernel.
Drivers, drivers and drivers. Not a single core change.
Some new stuff, especially a bunch of new Intel, Qualcomm and Ocelot
SoCs.
As part of the modularization attempt, I applied one patch affecting
the firmware subsystem as a functional (not syntactic/semantic)
dependency and then it blew up in our face, so I had to revert it,
bummer. It will come in later, through that subsystem, I guess.
New drivers:
- New driver for the Microchip Serial GPIO "SGPIO".
- Qualcomm SM8250 LPASS (Low Power Audio Subsystem) GPIO driver.
New subdrivers:
- Intel Lakefield subdriver.
- Intel Elkhart Lake subdriver.
- Intel Alder Lake-S subdriver.
- Qualcomm MSM8953 subdriver.
- Qualcomm SDX55 subdriver.
- Qualcomm SDX55 PMIC subdriver.
- Ocelot Luton SoC subdriver.
- Ocelot Serval SoC subdriver.
Modularization:
- The Meson driver can now be built as modules.
- The Qualcomm driver(s) can now be built as modules.
Incremental improvements:
- The Intel driver now supports pin configuration for GPIO-related
configurations.
- A bunch of Renesas PFC drivers have been augmented with support for
QSPI pins, groups and functions.
- Non-critical fixes to the irq handling in the Allwinner Sunxi
driver"

- Add timeout support for io_uring_enter(2), which enables us to
clean up liburing and avoid a timeout sqe submission in the

The big win here is that it allows setups that split SQ and CQ

Merge tag 'tif-task_work.arch-2020-12-14' of git://git.kernel.dk/linux-block
Pull TIF_NOTIFY_SIGNAL updates from Jens Axboe: "This sits on top of of the core entry/exit and x86 entry branch from the tip tree, which contains the generic and x86 parts of this work. Here we convert the rest of the archs to support TIF_NOTIFY_SIGNAL. With that done, we can get rid of JOBCTL_TASK_WORK from task_work and signal.c, and also remove a deadlock work-around in io_uring around knowing that signal based task_work waking is invoked with the sighand wait queue head lock. The motivation for this work is to decouple signal notify based task_work, of which io_uring is a heavy user of, from sighand. The sighand lock becomes a huge contention point, particularly for threaded workloads where it's shared between threads. Even outside of threaded applications it's slower than it needs to be. Roman Gershman <romger@amazon.com> reported that his networked workload dropped from 1.6M QPS at 80% CPU to 1.0M QPS at 100% CPU after io_uring was changed to use TIF_NOTIFY_SIGNAL. The time was all spent hammering on the sighand lock, showing 57% of the CPU time there [1]. There are further cleanups possible on top of this. One example is TIF_PATCH_PENDING, where a patch already exists to use TIF_NOTIFY_SIGNAL instead. Hopefully this will also lead to more consolidation, but the work stands on its own as well" [1] https://github.com/axboe/liburing/issues/215 * tag 'tif-task_work.arch-2020-12-14' of git://git.kernel.dk/linux-block: (28 commits) io_uring: remove 'twa_signal_ok' deadlock work-around kernel: remove checking for TIF_NOTIFY_SIGNAL signal: kill JOBCTL_TASK_WORK io_uring: JOBCTL_TASK_WORK is no longer used by task_work task_work: remove legacy TWA_SIGNAL path sparc: add support for TIF_NOTIFY_SIGNAL riscv: add support for TIF_NOTIFY_SIGNAL nds32: add support for TIF_NOTIFY_SIGNAL ia64: add support for TIF_NOTIFY_SIGNAL h8300: add support for TIF_NOTIFY_SIGNAL c6x: add support for TIF_NOTIFY_SIGNAL alpha: add support for TIF_NOTIFY_SIGNAL xtensa: add support for TIF_NOTIFY_SIGNAL arm: add support for TIF_NOTIFY_SIGNAL microblaze: add support for TIF_NOTIFY_SIGNAL hexagon: add support for TIF_NOTIFY_SIGNAL csky: add support for TIF_NOTIFY_SIGNAL openrisc: add support for TIF_NOTIFY_SIGNAL sh: add support for TIF_NOTIFY_SIGNAL um: add support for TIF_NOTIFY_SIGNAL ... |

This patch was discussed both with Herbert Xu (representing team

This lets all relay users make their struct rchan_callbacks const data. This series starts with a number of cleanups first based on Christoph's feedback.

lib: string.h: detect intra-object overflow in fortified string functions
Patch series "Fortify strscpy()", v7.
This patch implements a fortified version of strscpy() enabled by setting
CONFIG_FORTIFY_SOURCE=y. The new version ensures the following before
calling vanilla strscpy():
1. There is no read overflow because either size is smaller than src
length or we shrink size to src length by calling fortified strnlen().
2. There is no write overflow because we either failed during
compilation or at runtime by checking that size is smaller than dest
size. Note that, if src and dst size cannot be got, the patch defaults
to call vanilla strscpy().
The patches adds the following:
1. Implement the fortified version of strscpy().
2. Add a new LKDTM test to ensures the fortified version still returns
the same value as the vanilla one while panic'ing when there is a write
overflow.
3. Correct some typos in LKDTM related file.
I based my modifications on top of two patches from Daniel Axtens which
modify calls to __builtin_object_size, in fortified string functions, to
ensure the true size of char * are returned and not the surrounding
structure size.
About performance, I measured the slow down of fortified strscpy(), using
the vanilla one as baseline. The hardware I used is an Intel i3 2130 CPU
clocked at 3.4 GHz. I ran "Linux 5.10.0-rc4+ SMP PREEMPT" inside qemu
3.10 with 4 CPU cores. The following code, called through LKDTM, was used
as a benchmark:
#define TIMES 10000
char *src;
char dst[7];
int i;
ktime_t begin;
src = kstrdup("foobar", GFP_KERNEL);
if (src == NULL)
return;
begin = ktime_get();
for (i = 0; i < TIMES; i++)
strscpy(dst, src, strlen(src));
pr_info("%d fortified strscpy() tooks %lld", TIMES, ktime_get() - begin);
begin = ktime_get();
for (i = 0; i < TIMES; i++)
__real_strscpy(dst, src, strlen(src));
pr_info("%d vanilla strscpy() tooks %lld", TIMES, ktime_get() - begin);
kfree(src);
I called the above code 30 times to compute stats for each version (in ns,
round to int):
| version | mean | std | median | 95th |
| --------- | ------- | ------ | ------- | ------- |
| fortified | 245_069 | 54_657 | 216_230 | 331_122 |
| vanilla | 172_501 | 70_281 | 143_539 | 219_553 |
On average, fortified strscpy() is approximately 1.42 times slower than
vanilla strscpy(). For the 95th percentile, the fortified version is
about 1.50 times slower.
So, clearly the stats are not in favor of fortified strscpy(). But, the
fortified version loops the string twice (one in strnlen() and another in
vanilla strscpy()) while the vanilla one only loops once. This can
explain why fortified strscpy() is slower than the vanilla one.
This patch (of 5):
When the fortify feature was first introduced in commit

ilog2: improve ilog2 for constant arguments
As discussed in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97445 the const_ilog2 macro generates a lot of code which interferes badly with GCC inlining heuristics, until it can be proven that the ilog2 argument can or can't be simplified into a constant. It can be expressed using __builtin_clzll builtin which is supported by GCC 3.4 and later and when used only in the __builtin_constant_p guarded code it ought to always fold back to a constant. Other compilers support the same builtin for many years too. Other option would be to change the const_ilog2 macro, though as the description says it is meant to be used also in C constant expressions, and while GCC will fold it to constant with constant argument even in those, perhaps it is better to avoid using extensions in that case.

Merge tag 'nfsd-5.11' of git://git.linux-nfs.org/projects/cel/cel-2.6
Pull nfsd updates from Chuck Lever:
"Several substantial changes this time around:
- Previously, exporting an NFS mount via NFSD was considered to be an
unsupported feature. With v5.11, the community has attempted to
make re-exporting a first-class feature of NFSD.
This would enable the Linux in-kernel NFS server to be used as an
intermediate cache for a remotely-located primary NFS server, for
example, even with other NFS server implementations, like a NetApp
filer, as the primary.
- A short series of patches brings support for multiple RPC/RDMA data
chunks per RPC transaction to the Linux NFS server's RPC/RDMA
transport implementation.
This is a part of the RPC/RDMA spec that the other premiere
NFS/RDMA implementation (Solaris) has had for a very long time, and
completes the implementation of RPC/RDMA version 1 in the Linux
kernel's NFS server.
- Long ago, NFSv4 support was introduced to NFSD using a series of C
macros that hid dprintk's and goto's. Over time, the kernel's XDR
implementation has been greatly improved, but these C macros have
remained and become fallow. A series of patches in this pull
request completely replaces those macros with the use of current
kernel XDR infrastructure. Benefits include:
- More robust input sanitization in NFSD's NFSv4 XDR decoders.
- Make it easier to use common kernel library functions that use
XDR stream APIs (for example, GSS-API).
- Align the structure of the source code with the RFCs so it is
easier to learn, verify, and maintain our XDR implementation.
- Removal of more than a hundred hidden dprintk() call sites.
- Removal of some explicit manipulation of pages to help make the
eventual transition to xdr->bvec smoother.
- On top of several related fixes in 5.10-rc, there are a few more
fixes to get the Linux NFSD implementation of NFSv4.2 inter-server
copy up to speed.
And as usual, there is a pinch of seasoning in the form of a
collection of unrelated minor bug fixes and clean-ups.
Many thanks to all who contributed this time around!"
