fortify: fix warnings in fortify tests with KASAN
kbuild: rpm-pkg: avoid the warnings with dtb's listed twice
kbuild: Make ld-version.sh more robust against version string changes
|
|
When a software KASAN mode is enabled, the fortify tests emit warnings
on some architectures.
For example, for ARCH=arm, the combination of CONFIG_FORTIFY_SOURCE=y
and CONFIG_KASAN=y produces the following warnings:
TEST lib/test_fortify/read_overflow-memchr.log
warning: unsafe memchr() usage lacked '__read_overflow' warning in lib/test_fortify/read_overflow-memchr.c
TEST lib/test_fortify/read_overflow-memchr_inv.log
warning: unsafe memchr_inv() usage lacked '__read_overflow' symbol in lib/test_fortify/read_overflow-memchr_inv.c
TEST lib/test_fortify/read_overflow-memcmp.log
warning: unsafe memcmp() usage lacked '__read_overflow' warning in lib/test_fortify/read_overflow-memcmp.c
TEST lib/test_fortify/read_overflow-memscan.log
warning: unsafe memscan() usage lacked '__read_overflow' symbol in lib/test_fortify/read_overflow-memscan.c
TEST lib/test_fortify/read_overflow2-memcmp.log
warning: unsafe memcmp() usage lacked '__read_overflow2' warning in lib/test_fortify/read_overflow2-memcmp.c
[ more and more similar warnings... ]
Commit 9c2d1328f88a ("kbuild: provide reasonable defaults for tool
coverage") removed KASAN flags from non-kernel objects by default.
It was an intended behavior because lib/test_fortify/*.c are unit
tests that are not linked to the kernel.
As it turns out, some architectures require -fsanitize=kernel-(hw)address
to define __SANITIZE_ADDRESS__ for the fortify tests.
Without __SANITIZE_ADDRESS__ defined, arch/arm/include/asm/string.h
defines __NO_FORTIFY, thus excluding <linux/fortify-string.h>.
This issue does not occur on x86 thanks to commit 4ec4190be4cf
("kasan, x86: don't rename memintrinsics in uninstrumented files"),
but there are still some architectures that define __NO_FORTIFY
in such a situation.
Set KASAN_SANITIZE=y explicitly to the fortify tests.

After 8d1001f7bdd0 (kbuild: rpm-pkg: fix build error with CONFIG_MODULES=n),
the following warning "warning: File listed twice: *.dtb" is appearing for
every dtb file that is included.
The reason is that the commented commit already adds the folder
/lib/modules/%{KERNELRELEASE} in kernel.list file so the folder
/lib/modules/%{KERNELRELEASE}/dtb is no longer necessary, just remove it.

After [1] in upstream LLVM, ld.lld's version output became slightly
different when the cmake configuration option LLVM_APPEND_VC_REV is
disabled.
Before:
Debian LLD 19.0.0 (compatible with GNU linkers)
After:
Debian LLD 19.0.0, compatible with GNU linkers
This results in ld-version.sh failing with
scripts/ld-version.sh: 18: arithmetic expression: expecting EOF: "10000 * 19 + 100 * 0 + 0,"
because the trailing comma is included in the patch level part of the
expression. While [1] has been partially reverted in [2] to avoid this
breakage (as it impacts the configuration stage and it is present in all
LTS branches), it would be good to make ld-version.sh more robust
against such miniscule changes like this one.
Use POSIX shell parameter expansion [3] to remove the largest suffix
after just numbers and periods, replacing of the current removal of
everything after a hyphen. ld-version.sh continues to work for a number
of distributions (Arch Linux, Debian, and Fedora) and the kernel.org
toolchains and no longer errors on a version of ld.lld with [1].

If you try to set /proc/fs/cifs/SecurityFlags to 1 it
will set them to CIFSSEC_MUST_NTLMV2 which no longer is
relevant (the less secure ones like lanman have been removed
from cifs.ko) and is also missing some flags (like for
signing and encryption) and can even cause mount to fail,
so change this to set it to Kerberos in this case.
Also change the description of the SecurityFlags to remove mention
of flags which are no longer supported.

Pull btrfs fixes from David Sterba:
"Fix a regression in extent map shrinker behaviour.
In the past weeks we got reports from users that there are huge
latency spikes or freezes. This was bisected to newly added shrinker
of extent maps (it was added to fix a build up of the structures in
memory).
I'm assuming that the freezes would happen to many users after release
so I'd like to get it merged now so it's in 6.10. Although the diff
size is not small the changes are relatively straightforward, the
reporters verified the fixes and we did testing on our side.
The fixes:
- adjust behaviour under memory pressure and check lock or scheduling
conditions, bail out if needed
- synchronize tracking of the scanning progress so inode ranges are
not skipped or work duplicated
- do a delayed iput when scanning a root so evicting an inode does
not slow things down in case of lots of dirty data, also fix
lockdep warning, a deadlock could happen when writing the dirty
data would need to start a transaction"

QUICC ENGINE LIBRARY has Qiang Zhao as maintainer but he hasn't
responded for years and when Li Yang was still maintaining FREESCALE
SOC DRIVERS he was also handling QUICC ENGINE LIBRARY directly.
As a maintainer of LINUX FOR POWERPC EMBEDDED PPC8XX AND PPC83XX, I
also need FREESCALE SOC DRIVERS to be actively maintained, so add
myself as maintainer of FREESCALE SOC DRIVERS and QUICC ENGINE LIBRARY.

There are many generations of omaps to maintain, and I will be only active
as a hobbyist with time permitting. Let's add more maintainers to ensure
continued Linux support.
TI is interested in maintaining the active SoCs such as am3, am4 and
dra7. And the hobbyists are interested in maintaining some of the older
devices, mainly based on omap3 and 4 SoCs.
Kevin and Roger have agreed to maintain the active TI parts. Both Kevin
and Roger have been working on the omap variants for a long time, and
have a good understanding of the hardware.
Aaro and Andreas have agreed to maintain the community devices. Both Aaro
and Andreas have long experience on working with the earlier TI SoCs.
While at it, let's also change me to be a reviewer for the omap1, and
drop the link to my old omap web page.

Remove wrong EIO to EGAIN conversion and pass all errors as is.
After commit 230f3d53a547 ("i40e: remove i40e_status"), which should only
replace F/W specific error codes with Linux kernel generic, all EIO errors
suddenly started to be converted into EAGAIN which leads nvmupdate to retry
until it timeouts and sometimes fails after more than 20 minutes in the
middle of NVM update, so NVM becomes corrupted.
The bug affects users only at the time when they try to update NVM, and
only F/W versions that generate errors while nvmupdate. For example, X710DA2
with 0x8000ECB7 F/W is affected, but there are probably more...
Command for reproduction is just NVM update:
./nvmupdate64
In the log instead of:
i40e_nvmupd_exec_aq err I40E_ERR_ADMIN_QUEUE_ERROR aq_err I40E_AQ_RC_ENOMEM)
appears:
i40e_nvmupd_exec_aq err -EIO aq_err I40E_AQ_RC_ENOMEM
i40e: eeprom check failed (-5), Tx/Rx traffic disabled
The problematic code did silently convert EIO into EAGAIN which forced
nvmupdate to ignore EAGAIN error and retry the same operation until timeout.
That's why NVM update takes 20+ minutes to finish with the fail in the end.

When user submits a rxfh set command without touching XFRM_SYM_XOR,
rxfh.input_xfrm is set to RXH_XFRM_NO_CHANGE, which is equal to 0xff.
Testing if (rxfh.input_xfrm & RXH_XFRM_SYM_XOR &&
!ops->cap_rss_sym_xor_supported)
return -EOPNOTSUPP;
Will always be true on devices that don't set cap_rss_sym_xor_supported,
since rxfh.input_xfrm & RXH_XFRM_SYM_XOR is always true, if input_xfrm
was not set, i.e RXH_XFRM_NO_CHANGE=0xff, which will result in failure
of any command that doesn't require any change of XFRM, e.g RSS context
or hash function changes.
To avoid this breakage, test if rxfh.input_xfrm != RXH_XFRM_NO_CHANGE
before testing other conditions. Note that the problem will only trigger
with XFRM-aware userspace, old ethtool CLI would continue to work.

The other is a series of fixes from David Lechner for his recent

We store the progress (root and inode numbers) of the extent map shrinker
in fs_info without any synchronization but we can have multiple tasks
calling into the shrinker during memory allocations when there's enough
memory pressure for example.
This can result in a task A reading fs_info->extent_map_shrinker_last_ino
after another task B updates it, and task A reading
fs_info->extent_map_shrinker_last_root before task B updates it, making
task A see an odd state that isn't necessarily harmful but may make it
skip certain inode ranges or do more work than necessary by going over
the same inodes again. These unprotected accesses would also trigger
warnings from tools like KCSAN.
So add a lock to protect access to these progress fields.

The extent map shrinker can be called in a variety of contexts where we
are under memory pressure, and of them is when a task is trying to
allocate memory. For this reason the shrinker is typically called with a
value of struct shrink_control::nr_to_scan that is much smaller than what
we return in the nr_cached_objects callback of struct super_operations
(fs/btrfs/super.c:btrfs_nr_cached_objects()), so that the shrinker does
not take a long time and cause high latencies. However we can still take
a lot of time in the shrinker even for a limited amount of nr_to_scan:
1) When traversing the red black tree that tracks open inodes in a root,
as for example with millions of open inodes we get a deep tree which
takes time searching for an inode;
2) Iterating over the extent map tree, which is a red black tree, of an
inode when doing the rb_next() calls and when removing an extent map
from the tree, since often that requires rebalancing the red black
tree;
3) When trying to write lock an inode's extent map tree we may wait for a
significant amount of time, because there's either another task about
to do IO and searching for an extent map in the tree or inserting an
extent map in the tree, and we can have thousands or even millions of
extent maps for an inode. Furthermore, there can be concurrent calls
to the shrinker so the lock might be busy simply because there is
already another task shrinking extent maps for the same inode;
4) We often reschedule if we need to, which further increases latency.
So improve on this by stopping the extent map shrinking code whenever we
need to reschedule and make it skip an inode if we can't immediately lock
its extent map tree.

When putting an inode during extent map shrinking we're doing a standard
iput() but that may take a long time in case the inode is dirty and we are
doing the final iput that triggers eviction - the VFS will have to wait
for writeback before calling the btrfs evict callback (see
fs/inode.c:evict()).
This slows down the task running the shrinker which may have been
triggered while updating some tree for example, meaning locks are held
as well as an open transaction handle.
Also if the iput() ends up triggering eviction and the inode has no links
anymore, then we trigger item truncation which requires flushing delayed
items, space reservation to start a transaction and that may trigger the
space reclaim task and wait for it, resulting in deadlocks in case the
reclaim task needs for example to commit a transaction and the shrinker
is being triggered from a path holding a transaction handle.
Syzbot reported such a case with the following stack traces:
