5f8d411729 bpf: Fix handling maps with no BTF and non-constant offsets for the bpf_wq
Fix handling maps with no BTF and non-constant offsets for the bpf_wq.

This de-duplicates logic with other internal structs (task_work, timer),
keeps error reporting consistent, and makes future changes to the layout
handling centralized.

Paul Chaignon says:

====================
Support non-linear skbs for BPF_PROG_TEST_RUN

This patchset adds support for non-linear skbs when running tc programs
with BPF_PROG_TEST_RUN.

We've had multiple bugs in the past few years in Cilium caused by
missing calls to bpf_skb_pull_data(). Daniel suggested to support
non linear skb in BPF_PROG_TEST_RUN to uncover these bugs in
our BPF tests.

Changes in v8:
  - Fix uninitialized data pointer spotted by Martin.
  - Error out in test_loader if __linear_size tag is used on unsupported
    program types.
Changes in v7:
  - Refactor use of 'size' variable as suggested by Martin.
  - Support copying back the non-linear area to data_out.
  - Minor code changes for readability, suggested by Martin.
Changes in v6:
  - Disallow non-linear skb in prog_run_skb only for LWT programs
    instead of all non-L2 program types, on suggestion from Martin.
  - Reject non-null ctx->data and ctx->data_meta, as suggested by Amery.
  - Bound linear_size to 'PAGE_SIZE - headroom - tailroom' to be
    consistent with prog_run_xdp, as suggested by Martin.
  - Allocate exactly linear_size bytes in bpf_test_init, spotted by
    Martin.
  - Fix wrong conflict resolution on double-free fix, spotted by Amery.
  - Rebased.
Changes in v5:
  - Fix double free on data in first patch.
Changes in v4:
  - Per Martin's suggestion, follow the XDP code pattern and use
    bpf_test_init only to initialize the linear area. That way data is
    directly copied to the right areas and we avoid the call to
    __pskb_pull_tail.
  - Fixed outdated commit descriptions.
  - Rebased.
Changes in v3:
  - Dropped BPF_F_TEST_SKB_NON_LINEAR and used the ctx->data_end to
    determine if the user wants non-linear skb, as suggested by Amery.
  - Introduced a second commit with a bit of refactoring to allow for
    the above requested change.
  - Fix bug found by syzkaller on third commit.
  - Rebased.
Changes in v2:
  - Made the linear size configurable via ctx->data_end, as suggested
    by Amery.
  - Reworked the selftests to allow testing the configurable linear
    size.
  - Fix warnings reported by kernel test robot on first commit.
  - Rebased.

bc3eeb4259 selftests/bpf: Test direct packet access on non-linear skbs
This patch adds new selftests in the direct packet access suite, to
cover the non-linear case. The first six tests cover the behavior of
the bounds check with a non-linear skb. The last test adds a call to
bpf_skb_pull_data() to be able to access the packet.

Note that the size of the linear area includes the L2 header, but for
some program types like cgroup_skb, ctx->data points to the L3 header.
Therefore, a linear area of 22 bytes will have only 8 bytes accessible
to the BPF program (22 - ETH_HLEN). For that reason, the cgroup_skb test
cases access the packet at an offset of 8 bytes.

8d45d0398d selftests/bpf: Support non-linear flag in test loader
This patch adds support for a new tag __linear_size in the test loader,
to specify the size of the linear area in case of non-linear skbs. If

838baa351c bpf: Craft non-linear skbs in BPF_PROG_TEST_RUN
This patch adds support for crafting non-linear skbs in BPF test runs
for tc programs. The size of the linear area is given by ctx->data_end,
with a minimum of ETH_HLEN always pulled in the linear area. If ctx or
ctx->data_end are null, a linear skb is used.

This is particularly useful to test support for non-linear skbs in large
codebases such as Cilium. We've had multiple bugs in the past few years
where we were missing calls to bpf_skb_pull_data(). This support in
BPF_PROG_TEST_RUN would allow us to automatically cover this case in our
BPF tests.

LWT program types are currently excluded in this patch. Allowing
non-linear skbs for these programs would require a bit more care because
they are able to call helpers (ex., bpf_clone_redirect, bpf_redirect)
that themselves call eth_type_trans(). eth_type_trans() assumes there
are at least ETH_HLEN bytes in the linear area. That may not be true
for LWT programs as we already pulled the L2 header via the
eth_type_trans() call in bpf_prog_test_run_skb().

In addition to the selftests introduced later in the series, this patch
was tested by enabling non-linear skbs for all tc selftests programs
and checking test failures were expected.

57bb2f6717 bpf: Reorder bpf_prog_test_run_skb initialization
This patch reorders the initialization of bpf_prog_test_run_skb to
simplify the subsequent patch. Program types are checked first, followed
by the ctx init, and finally the data init. With the subsequent patch,
program types and the ctx init provide information that is used in the
data init. Thus, we need the data init to happen last.

4b471b736e ext4, doc: fix and improve directory hash tree description
Some of the details about how directory hash trees work were confusing or
outright wrong, this patch should fix those.

A note on dx_tail's dt_reserved member, as far as I can tell the kernel
never sets this explicitly, so its content is apparently left-overs from
what was there before (for the dx_root I've seen remnants of a
ext4_dir_entry_tail struct from when the dir was not yet a hash dir).

328a782cb1 ext4: wait for ongoing I/O to complete before freeing blocks
When freeing metadata blocks in nojournal mode, ext4_forget() calls
bforget() to clear the dirty flag on the buffer_head and remvoe
associated mappings. This is acceptable if the metadata has not yet
begun to be written back. However, if the write-back has already started
but is not yet completed, ext4_forget() will have no effect.
Subsequently, ext4_mb_clear_bb() will immediately return the block to
the mb allocator. This block can then be reallocated immediately,
potentially causing an data corruption issue.

Fix this by clearing the buffer's dirty flag and waiting for the ongoing
I/O to complete, ensuring that no further writes to stale data will
occur.

Merge patch series "kbuild: Fixes for fallout from recent modules.builtin.modinfo series"
This is a series to address some problems that were exposed by the
recent modules.builtin.modinfo series that landed in commit c7d3dd9163
("Merge patch series "Add generated modalias to
modules.builtin.modinfo"").

The third patch is not directly related to the aforementioned series, as
the warning it fixes happens prior to the series but commit 8d18ef04f9
("s390: vmlinux.lds.S: Reorder sections") from the series creates
conflicts in this area, so I included it here.

s390/vmlinux.lds.S: Move .vmlinux.info to end of allocatable sections
When building s390 defconfig with binutils older than 2.32, there are
several warnings during the final linking stage:

  s390-linux-ld: .tmp_vmlinux1: warning: allocated section `.got.plt' not in segment
  s390-linux-ld: .tmp_vmlinux2: warning: allocated section `.got.plt' not in segment

  s390-linux-objcopy: vmlinux: warning: allocated section `.got.plt' not in segment
  s390-linux-objcopy: st7afZyb: warning: allocated section `.got.plt' not in segment

binutils commit afca762f598 ("S/390: Improve partial relro support for
64 bit") [1] in 2.32 changed where .got.plt is emitted, avoiding the
warning.

The :NONE in the .vmlinux.info output section description changes the
segment for subsequent allocated sections. Move .vmlinux.info right
above the discards section to place all other sections in the previously
defined segment, .data.

kbuild: Add '.rel.*' strip pattern for vmlinux
Prior to binutils commit c12d9fa2afe ("Support objcopy
--remove-section=.relaFOO") [1] in 2.32, stripping relocation sections
required the trailing period (i.e., '.rel.*') to work properly.

After commit 3e86e4d74c ("kbuild: keep .modinfo section in
vmlinux.unstripped"), there is an error with binutils 2.31.1 or earlier
because these sections are not properly removed:

  s390-linux-objcopy: st6tO8Ev: symbol `.modinfo' required but not present
  s390-linux-objcopy:st6tO8Ev: no symbols

Add the old pattern to resolve this issue (along with a comment to allow
cleaning this when binutils 2.32 or newer is the minimum supported
version). While the aforementioned kbuild change exposes this, the
pattern was originally changed by commit 71d815bf5d ("kbuild: Strip
runtime const RELA sections correctly"), where it would still be
incorrect with binutils older than 2.32.

4f375ade6a bpf: Avoid RCU context warning when unpinning htab with internal structs
When unpinning a BPF hash table (htab or htab_lru) that contains internal
structures (timer, workqueue, or task_work) in its values, a BUG warning
is triggered:
 BUG: sleeping function called from invalid context at kernel/bpf/hashtab.c:244
 in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 14, name: ksoftirqd/0
 ...

The issue arises from the interaction between BPF object unpinning and
RCU callback mechanisms:
1. BPF object unpinning uses ->free_inode() which schedules cleanup via
   call_rcu(), deferring the actual freeing to an RCU callback that
   executes within the RCU_SOFTIRQ context.
2. During cleanup of hash tables containing internal structures,
   htab_map_free_internal_structs() is invoked, which includes
   cond_resched() or cond_resched_rcu() calls to yield the CPU during
   potentially long operations.

However, cond_resched() or cond_resched_rcu() cannot be safely called from
atomic RCU softirq context, leading to the BUG warning when attempting
to reschedule.

Fix this by changing from ->free_inode() to ->destroy_inode() and rename
bpf_free_inode() to bpf_destroy_inode() for BPF objects (prog, map, link).
This allows direct inode freeing without RCU callback scheduling,
avoiding the invalid context warning.

3c652c3a71 jbd2: ensure that all ongoing I/O complete before freeing blocks
When releasing file system metadata blocks in jbd2_journal_forget(), if
this buffer has not yet been checkpointed, it may have already been
written back, currently be in the process of being written back, or has
not yet written back.  jbd2_journal_forget() calls
jbd2_journal_try_remove_checkpoint() to check the buffer's status and
add it to the current transaction if it has not been written back. This
buffer can only be reallocated after the transaction is committed.

jbd2_journal_try_remove_checkpoint() attempts to lock the buffer and
check its dirty status while holding the buffer lock. If the buffer has
already been written back, everything proceeds normally. However, there
are two issues. First, the function returns immediately if the buffer is
locked by the write-back process. It does not wait for the write-back to
complete. Consequently, until the current transaction is committed and
the block is reallocated, there is no guarantee that the I/O will
complete. This means that ongoing I/O could write stale metadata to the
newly allocated block, potentially corrupting data. Second, the function
unlocks the buffer as soon as it detects that the buffer is still dirty.
If a concurrent write-back occurs immediately after this unlocking and
before clear_buffer_dirty() is called in jbd2_journal_forget(), data
corruption can theoretically still occur.

Although these two issues are unlikely to occur in practice since the
undergoing metadata writeback I/O does not take this long to complete,
it's better to explicitly ensure that all ongoing I/O operations are
completed.

07ca98f906 xsk: Harden userspace-supplied xdp_desc validation
Turned out certain clearly invalid values passed in xdp_desc from
userspace can pass xp_{,un}aligned_validate_desc() and then lead
to UBs or just invalid frames to be queued for xmit.

desc->len close to ``U32_MAX`` with a non-zero pool->tx_metadata_len
can cause positive integer overflow and wraparound, the same way low
enough desc->addr with a non-zero pool->tx_metadata_len can cause
negative integer overflow. Both scenarios can then pass the
validation successfully.
This doesn't happen with valid XSk applications, but can be used
to perform attacks.

Always promote desc->len to ``u64`` first to exclude positive
overflows of it. Use explicit check_{add,sub}_overflow() when
validating desc->addr (which is ``u64`` already).

bloat-o-meter reports a little growth of the code size:

add/remove: 0/0 grow/shrink: 2/1 up/down: 60/-16 (44)
Function                                     old     new   delta

xsk_generic_xmit                            3148    3132     -16

but hopefully this doesn't hurt the performance much.

Kumar Kartikeya Dwivedi says:

====================
Fix sleepable context tracking for async callbacks

Currently, asynchronous execution primitives set up their callback
execution simulation using push_async_cb, which will end up inheriting
the sleepable or non-sleepable bit from the program triggering the
simulation of the callback. This is incorrect, as the actual execution
context of the asynchronous callback has nothing to do with the program
arming its execution.

This set fixes this oversight, and supplies a few test cases ensuring
the correct behavior is tested across different types of primitives
(i.e. timer, wq, task_work).

While looking at this bug, it was noticed that the GFP flag setting
logic for storage_get helpers is also broken, hence fix it while we
are at it.

PSA: These fixes and unit tests were primarily produced by prompting an
AI assistant (Claude), and then modified in minor ways, in an exercise
to understand how useful it can be at general kernel development tasks.

5b1b5d380a selftests/bpf: Add tests for async cb context
Add tests to verify that async callback's sleepable attribute is
correctly determined by the callback type, not the arming program's
context, reflecting its true execution context.

Introduce verifier_async_cb_context.c with tests for all three async
callback primitives: bpf_timer, bpf_wq, and bpf_task_work. Each
primitive is tested when armed from both sleepable (lsm.s/file_open) and
non-sleepable (fentry) programs.

Test coverage:
- bpf_timer callbacks: Verify they are never sleepable, even when armed
  from sleepable programs. Both tests should fail when attempting to use
  sleepable helper bpf_copy_from_user() in the callback.

- bpf_wq callbacks: Verify they are always sleepable, even when armed
  from non-sleepable programs. Both tests should succeed when using
  sleepable helpers in the callback.

- bpf_task_work callbacks: Verify they are always sleepable, even when
  armed from non-sleepable programs. Both tests should succeed when
  using sleepable helpers in the callback.

f233d48559 bpf: Refactor storage_get_func_atomic to generic non_sleepable flag
Rename the storage_get_func_atomic flag to a more generic non_sleepable
flag that tracks whether a helper or kfunc may be called from a
non-sleepable context. This makes the flag more broadly applicable
beyond just storage_get helpers. See [0] for more context.

The flag is now set unconditionally for all helpers and kfuncs when:
- RCU critical section is active.
- Preemption is disabled.
- IRQs are disabled.
- In a non-sleepable context within a sleepable program (e.g., timer
  callbacks), which is indicated by !in_sleepable().

Previously, the flag was only set for storage_get helpers in these
contexts. With this change, it can be used by any code that needs to
differentiate between sleepable and non-sleepable contexts at the
per-instruction level.

The existing usage in do_misc_fixups() for storage_get helpers is
preserved by checking is_storage_get_function() before using the flag.

469d638d15 bpf: Fix sleepable context for async callbacks
Fix the BPF verifier to correctly determine the sleepable context of
async callbacks based on the async primitive type rather than the arming
program's context.

The bug is in in_sleepable() which uses OR logic to check if the current
execution context is sleepable. When a sleepable program arms a timer
callback, the callback's state correctly has in_sleepable=false, but
in_sleepable() would still return true due to env->prog->sleepable being
true. This incorrectly allows sleepable helpers like
bpf_copy_from_user() inside timer callbacks when armed from sleepable
programs, even though timer callbacks always execute in non-sleepable
context.

Fix in_sleepable() to rely solely on env->cur_state->in_sleepable, and
initialize state->in_sleepable to env->prog->sleepable in
do_check_common() for the main program entry. This ensures the sleepable
context is properly tracked per verification state rather than being
overridden by the program's sleepability.

The env->cur_state NULL check in in_sleepable() was only needed for
do_misc_fixups() which runs after verification when env->cur_state is
set to NULL. Update do_misc_fixups() to use env->prog->sleepable
directly for the storage_get_function check, and remove the redundant
NULL check from in_sleepable().

Introduce is_async_cb_sleepable() helper to explicitly determine async
callback sleepability based on the primitive type:
  - bpf_timer callbacks are never sleepable
  - bpf_wq and bpf_task_work callbacks are always sleepable

Add verifier_bug() check to catch unhandled async callback types,
ensuring future additions cannot be silently mishandled. Move the
is_task_work_add_kfunc() forward declaration to the top alongside other
callback-related helpers. We update push_async_cb() to adjust to the new
changes.

At the same time, while simplifying in_sleepable(), we notice a problem
in do_misc_fixups. Fix storage_get helpers to use GFP_ATOMIC when called
from non-sleepable contexts within sleepable programs, such as bpf_timer
callbacks.

Currently, the check in do_misc_fixups assumes that env->prog->sleepable,
previously in_sleepable(env) which only resolved to this check before
last commit, holds across the program's execution, but that is not true.
Instead, the func_atomic bit must be set whenever we see the function
being called in an atomic context. Previously, this is being done when
the helper is invoked in atomic contexts in sleepable programs, we can
simply just set the value to true without doing an in_sleepable() check.

We must also do a standalone in_sleepable() check to handle cases where
the async callback itself is armed from a sleepable program, but is
itself non-sleepable (e.g., timer callback) and invokes such a helper,
thus needing the func_atomic bit to be true for the said call.

Adjust do_misc_fixups() to drop any checks regarding sleepable nature of
the program, and just depend on the func_atomic bit to decide which GFP
flag to pass.

84d4e8b613 Hi,
Round #2.
 
 O_EXCL patches will be postponed to 6.19 as they need some restructuring.
 E.g., there's in-between series regression breaking the user space as lack
 of O_EXCL flag handling causes obviously unconditional O_EXCL.
 
 As per Chris' feedback, commands fail because it is based on Google's a
 non-standard proprietary TPM alike implementation. And the issue is not
 PC Client Profile specific. "typical profiles" are fine when they become
 "typical profiles".
 
 The null key can be verified with vendor certificate tied keys, and there's
 challenge-response process using them for certifying any other key by a
 remote party.
 
 Performance hit on generation aside, if really starting to cut hairs null
 keys are the most secure option, and it's a non-debatable fact: they have
 shortest expiration times as seed changes per power cycle.
 
 Based on this TCG_TPM2_HMAC is disabled from defconfig exactly for the sake
 of the performance issues.
 
 BR, Jarkko

75188605c5 drm/xe: Handle mixed mappings and existing VRAM on atomic faults
Moving to VRAM will fail if mixed mappings are present or if the page is
already located in VRAM. Atomic faults that require a move to VRAM
currently retry without attempting to evict mixed mappings or locate
existing VRAM mappings.

This patch fixes the issue by attempting to evict mixed mappings or find
existing VRAM pages when a move to VRAM fails during atomic fault
handling.
