Pull xfs updates from Darrick Wong:
"Here's a big pile of new stuff for XFS for 5.2. XFS has grown the
ability to report metadata health status to userspace after online
fsck checks the filesystem. The online metadata checking code is (I
really hope) feature complete with the addition of checks for the
global fs counters, though it'll remain EXPERIMENTAL for now.
There are also fixes for thundering herds of writeback completions and
some other deadlocks, fixes for theoretical integer overflow attacks
on space accounting, and removal of the long-defunct 'mntpt' option
which was deprecated in the mid-2000s and (it turns out) totally
broken since 2011 (and nobody complained...).
Summary:
- Fix some more buffer deadlocks when performing an unmount after a
hard shutdown.
- Fix some minor space accounting issues.
- Fix some use after free problems.
- Make the (undocumented) FITRIM behavior consistent with other
filesystems.
- Embiggen the xfs geometry ioctl's data structure.
- Introduce a new AG geometry ioctl.
- Introduce a new online health reporting infrastructure and ioctl
for userspace to query a filesystem's health status.
- Enhance online scrub and repair to update the health reports.
- Reduce thundering herd problems when writeback io completes.
- Fix some transaction reservation type errors.
- Fix integer overflow problems with delayed alloc reservation
counters.
- Fix some problems where we would exit to userspace without
unlocking.
- Fix inconsistent behavior when finishing deferred ops fails.
- Strengthen scrub to check incore data against ondisk metadata.
- Remove long-broken mntpt mount option.
- Add an online scrub function for the filesystem summary counters,
which should make online metadata scrub more or less feature
complete for now.
- Various cleanups"

Pull btrfs updates from David Sterba:
"This time the majority of changes are cleanups, though there's still a
number of changes of user interest.
User visible changes:
- better read time and write checks to catch errors early and before
writing data to disk (to catch potential memory corruption on data
that get checksummed)
- qgroups + metadata relocation: last speed up patch int the series
to address the slowness, there should be no overhead comparing
balance with and without qgroups
- FIEMAP ioctl does not start a transaction unnecessarily, this can
result in a speed up and less blocking due to IO
- LOGICAL_INO (v1, v2) does not start transaction unnecessarily, this
can speed up the mentioned ioctl and scrub as well
- fsync on files with many (but not too many) hardlinks is faster,
finer decision if the links should be fsynced individually or
completely
- send tries harder to find ranges to clone
- trim/discard will skip unallocated chunks that haven't been touched
since the last mount
Fixes:
- send flushes delayed allocation before start, otherwise it could
miss some changes in case of a very recent rw->ro switch of a
subvolume
- fix fallocate with qgroups that could lead to space accounting
underflow, reported as a warning
- trim/discard ioctl honours the requested range
- starting send and dedupe on a subvolume at the same time will let
only one of them succeed, this is to prevent changes that send
could miss due to dedupe; both operations are restartable
Core changes:
- more tree-checker validations, errors reported by fuzzing tools:
- device item
- inode item
- block group profiles
- tracepoints for extent buffer locking
- async cow preallocates memory to avoid errors happening too deep in
the call chain
- metadata reservations for delalloc reworked to better adapt in
many-writers/low-space scenarios
- improved space flushing logic for intense DIO vs buffered workloads
- lots of cleanups
- removed unused struct members
- redundant argument removal
- properties and xattrs
- extent buffer locking
- selftests
- use common file type conversions
- many-argument functions reduction"

When desc filling fails in hns3_nic_net_xmit, it will call
hns3_clear_desc to unmap the dma mapping. But currently the
ring->next_to_use points to the desc where the desc filling
or dma mapping return error, which means the desc that
ring->next_to_use points to has not done the dma mapping,
the desc that need unmapping is before the ring->next_to_use.
This patch fixes it by calling ring_ptr_move_bw(next_to_use)
before doing unmapping operation, and set desc_cb->dma to
zero to avoid freeing it again when unloading.
Also, when filling skb head or frag fails, both need to unmap
all the way back to next_to_use_head, so remove one desc filling
error handling.

So this patch adds hns3_set_l2l3l4 to fill the inner(/normal)

According to hardware user manual, the tunnel packet type is

The VLAN aware bridge offloading is similar to the VLAN unaware
offloading, this makes it possible to offload the VLAN bridge
functionalities.
The hardware supports up to 64 VLAN bridge entries, we already use one
entry for each LAN port to prevent forwarding of packets between the
ports when the ports are not in a bridge, so in the end we have 57
possible VLANs.
The VLAN filtering is currently only active when the ports are in a
bridge, VLAN filtering for ports not in a bridge is not implemented.
It is currently not possible to change between VLAN filtering and not
filtering while the port is already in a bridge, this would make the
driver more complicated.
The VLANs are only defined on bridge entries, so we will not add
anything into the hardware when the port joins a bridge if it is doing
VLAN filtering, but only when an allowed VLAN is added.

This allows to offload bridges with DSA to the switch hardware and do
the packet forwarding in hardware.
This implements generic functions to access the switch hardware tables,
which are used to control many features of the switch.
This patch activates the MAC learning by removing the MAC address table
lock, to prevent uncontrolled forwarding of packets between all the LAN
ports, they are added into individual bridge tables entries with
individual flow ids and the switch will do the MAC learning for each
port separately before they are added to a real bridge.
Each bridge consist of an entry in the active VLAN table and the VLAN
mapping table, table entries with the same index are matching. In the
VLAN unaware mode we configure everything with VLAN ID 0, but we use
different flow IDs, the switch should handle all VLANs as normal payload
and ignore them. When the hardware looks for the port of the destination
MAC address it only takes the entries which have the same flow ID of the
ingress packet.
The bridges are configured with 64 possible entries with these
information:
Table Index, 0...63
VLAN ID, 0...4095: VLAN ID 0 is untagged
flow ID, 0..63: Same flow IDs share entries in MAC learning table
port map, one bit for each port number
tagged port map, one bit for each port number

Allow the special tag in ingress only on the CPU port and not on all

Pull x86 FPU state handling updates from Borislav Petkov:
"This contains work started by Rik van Riel and brought to fruition by
Sebastian Andrzej Siewior with the main goal to optimize when to load
FPU registers: only when returning to userspace and not on every
context switch (while the task remains in the kernel).
In addition, this optimization makes kernel_fpu_begin() cheaper by
requiring registers saving only on the first invocation and skipping
that in following ones.
What is more, this series cleans up and streamlines many aspects of
the already complex FPU code, hopefully making it more palatable for
future improvements and simplifications.
Finally, there's a __user annotations fix from Jann Horn"

Implement the setting of YFS ACLs in AFS through the interface of setting
the afs.yfs.acl extended attribute on the file.
Signed-off-by: David Howells <[email protected]>
|
|
The YFS/AuriStor variant of AFS provides more capable ACLs and provides
per-volume ACLs and per-file ACLs as well as per-directory ACLs. It also
provides some extra information that can be retrieved through four ACLs:
(1) afs.yfs.acl
The YFS file ACL (not the same format as afs.acl).
(2) afs.yfs.vol_acl
The YFS volume ACL.
(3) afs.yfs.acl_inherited
"1" if a file's ACL is inherited from its parent directory, "0"
otherwise.
(4) afs.yfs.acl_num_cleaned
The number of of ACEs removed from the ACL by the server because the
PT entries were removed from the PTS database (ie. the subject is no
longer known).

Implement an xattr on AFS files called "afs.acl" that retrieves a file's
ACL. It returns the raw AFS3 ACL from the result of calling FS.FetchACL,
leaving any interpretation to userspace.
Note that whilst YFS servers will respond to FS.FetchACL, this will render
a more-advanced YFS ACL down. Use "afs.yfs.acl" instead for that.

The AFS3 FID is three 32-bit unsigned numbers and is represented as three
up-to-8-hex-digit numbers separated by colons to the afs.fid xattr.
However, with the advent of support for YFS, the FID is now a 64-bit volume
number, a 96-bit vnode/inode number and a 32-bit uniquifier (as before).
Whilst the sprintf in afs_xattr_get_fid() has been partially updated (it
currently ignores the upper 32 bits of the 96-bit vnode number), the size
of the stack-based buffer has not been increased to match, thereby allowing
stack corruption to occur.
Fix this by increasing the buffer size appropriately and conditionally
including the upper part of the vnode number if it is non-zero. The latter
requires the lower part to be zero-padded if the upper part is non-zero.

While it's not possible to give an accurate number for the blocks
used on the server, populate i_blocks based on the file size so
that 'du' can give a reasonable estimate.
The value is rounded up to 1K granularity, for consistency with
what other AFS clients report, and the servers' 1K usage quota
unit. Note that the value calculated by 'du' at the root of a
volume can still be slightly lower than the quota usage on the
server, as 0-length files are charged 1 quota block, but are
reported as occupying 0 blocks. Again, this is consistent with
other AFS clients.

Log more information when "kAFS: AFS vnode with undefined type\n" is
displayed due to a vnode record being retrieved from the server that
appears to have a duff file type (usually 0). This prints more information
to try and help pin down the problem.

This issue is found by running liburing/test/io_uring_setup test.
When test run, the testcase "attempt to bind to invalid cpu" would not
pass with messages like:
io_uring_setup(1, 0xbfc2f7c8), \
flags: IORING_SETUP_SQPOLL|IORING_SETUP_SQ_AFF, \
resv: 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000, \
sq_thread_cpu: 2
expected -1, got 3
FAIL
On my system, there is:
CPU(s) possible : 0-3
CPU(s) online : 0-1
CPU(s) offline : 2-3
CPU(s) present : 0-1
The sq_thread_cpu 2 is offline on my system, so the bind should fail.
But cpu_possible() will pass the check. We shouldn't be able to bind
to an offline cpu. Use cpu_online() to do the check.
After the change, the testcase run as expected: EINVAL will be returned
for cpu offlined.

Problem:
When a kernel module is compiled as a separate module, some important
information about the kernel module is available via .modinfo section of
the module. In contrast, when the kernel module is compiled into the
kernel, that information is not available.
Information about built-in modules is necessary in the following cases:
1. When it is necessary to find out what additional parameters can be
passed to the kernel at boot time.
2. When you need to know which module names and their aliases are in
the kernel. This is very useful for creating an initrd image.
Proposal:
The proposed patch does not remove .modinfo section with module
information from the vmlinux at the build time and saves it into a
separate file after kernel linking. So, the kernel does not increase in
size and no additional information remains in it. Information is stored
in the same format as in the separate modules (null-terminated string
array). Because the .modinfo section is already exported with a separate
modules, we are not creating a new API.
It can be easily read in the userspace:
$ tr '\0' '\n' < modules.builtin.modinfo

These files do not define (USBHS_)DRIVER_NAME. Yet, they can be
successfully compiled because they are never built as a module by
anyone, i.e, the MODULE_ALIAS() calls are always no-op.
A problem showed up when a patch "moduleparam: Save information about
built-in modules in separate file" was applied. With this new feature,
MODULE_*() will be populated even if the callers are built-in.
To avoid the build errors, the lines referencing to the undefined
macro must be removed.
The complete fix is to remove all MODULE_* and #include <linux/module.h>
like many "make ... explicitly non-modular" commits did.
For now, I am touching only the offending lines.
