selftests/mm: fix potential wild pointer access of getline due to missing init
This is another occurrence of using getline where the code assumes that
getline allocates memory to store the line, but the pointer passed to it
is uninitialized and potentially a non-null pointer. This violates the
Open Group Spec[1] and caused a segfault in a similar situation in
selftest/clone3/clone3_set_tid. Fix it by initializing the line pointer
to NULL.
The issue has been found by simply grepping through the selftest code
after running into the issue in clone3_set_tid. Whether it segfaults in
its current state is unknown to me. But it's good to be addressed due to
defensive reasons.

selftests/clone3: fix wild pointer access of getline due to missing init
Patch series "selftests: Add missing initalization of pointer passed to
getline", v2.
This patch (of 2):
Clone3_set_tid uses getline(&line, ...) in a loop to read the child's
process status. The code expects that getline allocates the buffer for
the line on the first loop iteration. According to the Open Group
Spec[1], char *line has to be null pointer for this:
> ssize_t getline(char **restrict lineptr, ...);
> If *lineptr is a null pointer or if the object pointed to by *lineptr
> is of insufficient size, an object shall be allocated as if by
malloc()
> or the object shall be reallocated as if by realloc()[...].
However, char *line is only declared, leading to an undefined value that
is potentially non-null. In an example run with Musl v1.2.6, the realloc
call[2] of getdelim, which implements getline, triggers a segfault:
./run_kselftest.sh --test clone3:clone3_set_tid
[ 1366.165898] kselftest: Running tests in clone3
...
[ 1367.799244] clone3_set_tid[811]: unhandled signal 11 code 0x1 at

[ 1367.805314] t0 : 0x0000003fbf63d000
...
Looking at the realloc implementation, Musl mallocs for a null pointer
memory. But for a non-null pointer, it assumes it's passed a valid
pointer to the heap and tries to access its meta-data. This leads to the
segfault we see:
void *realloc(void *p, size_t n)
{
if (!p) return malloc(n);
if (size_overflows(n)) return 0;
struct meta *g = get_meta(p);
...
}
Fix this by properly initializing the line pointer to NULL.

Pull vfs fixes from Christian Brauner:
- vfs: Preserve the ACL_DONT_CACHE state in forget_cached_acl().
ACL_DONT_CACHE is meant to be a permanent opt-out from ACL caching
which FUSE relies on for servers that don't negotiate FUSE_POSIX_ACL.
The helper replaced it with ACL_NOT_CACHED, silently re-enabling the
cache, and as fuse doesn't invalidate the cache for such servers a
properly timed get_acl() returned stale ACLs. Comes with a fuse
selftest reproducing this.
- pidfs:
- Preserve PIDFD_THREAD when a thread pidfd is reopened via
open_by_handle_at(). PIDFD_THREAD shares the O_EXCL bit which
do_dentry_open() strips after the flags have been validated, so
the reopened pidfd silently became a process pidfd. Comes with a
selftest.
- Add a pidfs_dentry_open() helper so the regular pidfd allocation
path and the file handle path share the code that forces O_RDWR
and reapplies the pidfd flags that do_dentry_open() strips.
- Handle FS_IOC32_GETVERSION in the compat ioctl path.
- Make pidfs_ino_lock static.
- iomap:
- Fix the block range calculation in ifs_clear_range_dirty() so a
partial clear doesn't drop the dirty state of blocks the range
only partially covers.
- Support invalidating partial folios so a partial truncate or hole
punch with blocksize < foliosize doesn't leave stale dirty bits
behind.
- Only set did_zero when iomap_zero_iter() actually zeroed
something.
- Guard ifs_set_range_dirty() and ifs_set_range_uptodate() against
zero-length ranges where the unsigned last-block calculation
underflows and bitmap_set() writes far beyond the ifs->state
allocation.
- Don't merge ioends with different io_private values as the merge
could leak or corrupt the private data of the individual ioends.
- exec:
- Raise bprm->have_execfd only once the binfmt_misc interpreter has
actually been opened. The flag was set as soon as a matching 'O'
or 'C' entry was found. If the interpreter open failed with
ENOEXEC the exec fell through to the next binary format with
have_execfd raised but no executable staged and begin_new_exec()
NULL derefed past the point of no return.
- Fix an unsigned loop counter wrap in transfer_args_to_stack() on
nommu. An overlong argument or environment string pushes bprm->p
below PAGE_SIZE, the stop index becomes zero, and the loop never
terminates, wrapping its counter and copying garbage from in
front of the page array into the new process stack.
- Make binfmt_elf_fdpic only honour the first PT_INTERP like
binfmt_elf does. Each additional PT_INTERP overwrote the previous
interpreter, leaking the name allocation and the interpreter file
reference together with the write denial open_exec() took,
leaving the file unwritable for as long as the system runs.
- overlayfs:
- Compare the full escaped xattr prefix including the trailing dot.
An xattr like "trusted.overlay.overlayfoo" was misclassified as
an escaped overlay xattr.
- Check read access to the copy_file_range() source with the
source's mounter credentials.
- super: Thawing a filesystem whose block device was frozen with
bdev_freeze() deadlocked. Dropping the last block layer freeze
reference from under s_umount ends up in fs_bdev_thaw() which
reacquires s_umount on the same task. Pin the superblock with an
active reference instead and call bdev_thaw() without holding
s_umount.
- procfs: Return EACCES instead of success when the ptrace access check
for namespace links fails.
- afs: Use afs_dir_get_block() rather than afs_dir_find_block() for
block 0 in afs_edit_dir_remove(), matching afs_edit_dir_add().
- Push the memcg gating of ->nr_cached_objects() down into the btrfs
and shmem callbacks instead of skipping every callback during
non-root memcg reclaim. The blanket check short-circuited XFS whose
inode reclaim hook is intentionally driven from per-memcg contexts to
free memcg-charged slab.
- eventpoll: Pin files while checking reverse paths.
Since struct file became SLAB_TYPESAFE_BY_RCU a concurrent close
could free and recycle the file under the check which then took and
dropped the f_lock of whatever live file now occupies that slot.

tracing fix for 7.2:
- Move rb_desc->nr_page_va before updating dynamic array The rb_descr->page_va is a dynamic array counted by nr_page_va. But the updating of the page_va[] is done before the nr_page_va is incremented causing a build with CONFIG_UBSAN_BOUNDS to flag it as an overflow. Move the increment of the counted by value before the array element is updated. - Propagate errors from remote event bulk updates The return value of trace_remote_enable_event() was not being checked by remote_events_dir_enable_write() where it would silently fail. Have it check the return value and propagate that back up to user space. - Fix resource leak on mmiotrace trace_pipe close The mmiotrace tracer was created in 2008 before the trace_pipe had a close callback to allow tracers to do clean up from trace_pipe open. The trace_pipe close cleanup callback was added in 2009 but the mmiotrace tracer was not updated. It had a hack to do the cleanup in the read call, where it may leak if user space did not read the entire buffer. Add a callback to mmiotrace trace_pipe close do to the cleanup properly. - Fix a possible NULL pointer dereference in the mmiotrace tracer If the mmio_pipe_open() fails to find a PCI device, it will set the hiter->dev pointer to NULL. The read function will blindly dereference that pointer. Fix the read call to check to see if that pointer is populated before dereferencing it. - Fix union collision of module and refcnt for dynamic events In 'struct trace_event_call', the 'module' pointer and the 'refcnt' atomic variable share the same memory space in a union. The filter on module logic only checked if the 'module' was set to determine if the event belonged to the module. As dynamic events are always builtin, it doesn't need the 'module' field of the structure and used a refcount. But the module filtering logic would then mistaken these dynamic events as a module and call module_name(event->module) on it. Add a check to see if the event is a dynamic event and if so, do not check it for being part of the given module. - Reset the top level buffer in selftests before running instances The ftracetest selftest initializes each instance before executing the tests. But it does not reset the top level buffer. Dynamic events are only added and removed by the top level so any left over dynamic events will not be removed by the reset in the instances. Left over dynamic events can cause the tests to incorrectly fail. Reset the top level buffer before running the instances. - Make the context_switch counter 64 bit The code to read user space for a system call trace event or for a trace_marker will disable migration, enable preemption, read user space into a per CPU buffer, disable preemption and enable migration again. It checks if the per CPU context switch counter to see if it changed, and if it did not, it would know that the per CPU buffer was not touched by another task. But the save counter was 32 bit and it would compare it to the 64 bit context_switch variable. A long running system could have the context_switch variable greater that 1<<32 in which case the compare will always fail. The compare will promote the 32 bit int saved value to 64 bit and compare it to the full 64 bit counter. Since the top 32 bits of the saved value was zero, it would never match. - Fix a use-after-free of the event_enable trigger The event_enable trigger allows for enabling one event when another event is triggered. When the trigger is removed, it must go through a synchronization phase to make sure it is not triggered again. The trigger itself is delayed by the "bulk delay" logic that was recently added. But the code that frees the event_enable data used to rely on the trigger code to do the synchronization. Now that the code uses the call RCU functions (and a workqueue), that delay no longer is there. Add a callback private_data_free() function that allows triggers to clean up data after the synchronization phase has completed. - Move the module_ref counter into the delay callback Since an event of the event_enable trigger can enable an event for a module, it ups the module ref count for that event's module. This prevents the event from trying to enable an event that no longer exists and cause a use-after-free bug. The ref counter was set back down when the trigger was removed but not after thy synchronization phase. This could lead to the module data being accessed after module was unloaded. Move the module ref decrement into the private_data_free() callback of the event_enable trigger. - Add mutex to protect parser in ftrace filtering The set_ftrace_filter file uses a parsing descriptor that is allocated at open and modified by writes. If multiple threads were to write to the descriptor at the same time, it can corrupt the parser. Add a mutex around the modifications of the parser descriptor. - Fix possible corruption in perf syscall tracing The perf system call trace events can now read user space. To do so, the reads of user space enable preemption and disables it again. During this time that preemption is enabled, the task can migrate. The perf event list head is assigned via a per CPU pointer. It is done before the user space part is called. If the user space reading migrates the task to another CPU, then the head pointer is no longer valid. Re-assign the head pointer after the reading of user space to keep it using the correct data. -----BEGIN PGP SIGNATURE----- iIoEABYKADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCamYDGhQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qkhYAP9G5wDTVQQzitl900iWp9rvQ2Qm5UWN JDnK2HO1elmj0AD8CRiHBI5W3O2yUmoO4bOFZ9YFXz+DqJ1jwkDs5FfqjAU= =EMD9 -----END PGP SIGNATURE----- Merge tag 'trace-v7.2-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Move rb_desc->nr_page_va before updating dynamic array The rb_descr->page_va is a dynamic array counted by nr_page_va. But the updating of the page_va[] is done before the nr_page_va is incremented causing a build with CONFIG_UBSAN_BOUNDS to flag it as an overflow. Move the increment of the counted by value before the array element is updated. - Propagate errors from remote event bulk updates The return value of trace_remote_enable_event() was not being checked by remote_events_dir_enable_write() where it would silently fail.

The trace_pipe close cleanup callback was added in 2009 but the mmiotrace tracer was not updated.

====================
Netfilter/IPVS fixes for net
The following batch contains Netfilter/IPVS fixes for net. This batch
includes a mix of IPVS follow ups related to Sashiko reports, as well as
crash fixes for connection tracking expectation, helpers, ipset and
nf_tables mostly for old bugs. This also includes a fix for the
flowtable tunnel selftest.
1) Use s32 instead of s16 to calculate the remaining payload containing
SIP messages, otherwise underflow is possible allowing out-of-bound
memory access beyond the skb->data area. From Xiang Mei.
2) Fix the counter check in the flowtable selftest for tunnels, from
Lorenzo Bianconi.
3) Add and use nf_ct_expect_related_pair() to add the RTP and RTCP
expectations under the expectation lock, this is required by the SIP
and H.323 NAT helpers. This fixes a possible reinsertion of an
expectation with the DEAD flag set on while looping to find
consecutive ports.
4) Fix ipset UaF during table resize by blocking comment updates on
kernel-side adds. From David Lee.
5) Do not propagate the IP_VS_CONN_F_ONE_PACKET flag when using IPVS
state synchronization, otherwise reaching stale freed from
ip_vs_conn struct is possible, Zhiling Zou.
6) Adjust the hn1 hash node when the forwarding method changes between
MASQ and non-MASQ for an already hashed connection. This can leave
stale hash nodes pointing to a freed struct ip_vs_conn and trigger
UaF while reading /proc/net/ip_vs_conn. From Julian Anastasov.
7) nft_object rhltable needs to be per table, just like chain rhltable,
otherwise UaF from object lookup path while netns is being released.
There is also the nlevent path that can reach stale objects. Placing
this rhltable under the table hierarchy fixes this issue.
8) Reject invalid combined usage of hashlimit tables with and without
XT_HASHLIMIT_RATE_MATCH flag mode, otherwise access to uninitialized
.burst field of dsthash_ent is possible.
9) Fix checksum validations in IPVS performed from LOCAL_IN,
from Julian Anastasov.
10) Fix incorrect packet offset to layer 4 protocol in IPVS, uncovered
by Sashiko, from Julian Anastasov.
11) Skip the mangling of ICMP replies for non-first fragments, also
reported by Sashiko. Also from Julian.
12) Clear ip_vs_conn flags under the spinlock to fix a possible data
race. From Julian Anastasov.
13) Fix incorrect calculation of the payload bitmask in the nf_tables
hardware offload support, leading to UBSAN splat. From Xiang Mei.

selftests/xsk: account reclaimed invalid Tx descriptors
Invalid Tx descriptors are now returned through the completion ring, regardless of whether they form a standalone packet or belong to an invalid multi-buffer packet. The selftests previously counted only descriptors belonging to valid packets, with a special exception for some invalid multi-buffer packets in verbatim streams. This undercounts completion entries when a standalone invalid descriptor or another invalid packet is reclaimed by the kernel. Keep valid_pkts as the number of packets expected on the Rx side, but count every descriptor submitted to the Tx ring in valid_frags, as every such descriptor is now expected to be returned through the completion ring. Make fragment counting in verbatim mode follow the packet boundary instead of stopping at the first invalid fragment. Update custom stream generation so an invalid middle fragment terminates the generated Rx packet while Tx completion accounting still covers the complete invalid packet. Also add explicit end fragments after invalid middle descriptors. This exercises the kernel drain logic and verifies that subsequent valid packets are not interpreted as continuations of the invalid packet.

selftests/xsk: fix too-many-frags multi-buffer Tx test
The too-many-frags test describes a packet that is valid from the Tx ring ownership point of view, but invalid for transmission because it exceeds the supported number of fragments. Keep the generated Tx descriptors valid so that __send_pkts() accounts them as outstanding descriptors that must be reclaimed through the CQ. Then mark the corresponding Rx packet invalid so the test still does not expect the oversized packet to appear on the receive side. Add a valid synchronization packet after the oversized packet so the test can verify that the Tx path drains the bad packet and resumes at the next packet boundary.

selftests/net/af_unix: test listen() rejects wrong socket states
Add a regression test for the unix_listen() state check. The key case is
listen() on a bound socket that has already been connected: it is no
longer in TCP_CLOSE or TCP_LISTEN, so it must fail with EINVAL. A
prepare_peercred() call slipped in ahead of that check once left err at 0
and made listen() silently succeed there instead; this guards against a
repeat.
The neighbouring outcomes are covered too so they cannot regress the same
way: a bound socket in TCP_CLOSE listens fine, calling listen() again on a
socket already in TCP_LISTEN is allowed, and an unbound socket fails with
EINVAL.
Each case runs for both listenable socket types (SOCK_STREAM and
SOCK_SEQPACKET) and both pathname and abstract addresses.

selftests/ftrace: Reset triggers at top level before instance loop
When running instance tests, 'ftracetest' creates a new ftrace instance
and runs the tests inside it. Before starting each test, it executes
'initialize_system()' to reset the ftrace state to initial-state.
However, since 'initialize_system()' is executed in the context of the
instance directory, it only cleans up triggers and filters of that
instance.
Any triggers or dynamic events left behind in the top-level instance by
previous failed top-level tests, are left completely untouched. These
top-level leftovers can cause subsequent instance-based tests to fail
or even crash the kernel.
Fix this by executing 'initialize_system()' in the top-level tracing
directory once before entering the instance loop.

selftests/net: packetdrill: cover RST validation in SYN-RECEIVED
Add packetdrill coverage for the RFC 9293 reset checks on request sockets in SYN-RECEIVED. Verify that an exact RST removes the request, a non-exact in-window RST sends a challenge ACK without removing it, and an out-of-window RST is silently discarded. Also cover an RST|ACK with an unacceptable ACK number to ensure RST sequence validation runs before ACK-field validation.

selftests: netfilter: nft_flowtable.sh: fix offload counter verification for tunnel tests
The IPIP and IP6IP6 tunnel tests call check_counters() to verify flowtable offloading occurred, but the flow-add rule only matches meta oif "veth1". When traffic is routed through a tunnel device, oif is the tunnel interface (tun0, tun6, etc.), not veth1, so the flow-add rule never fires, no flowtable entry is created, and counters stay at zero — producing a silent false pass. Fix by adding tunnel-specific flow-add rules for each tunnel interface. These match TCP dport 12345 traffic before the bare accept rule, set ct mark, add the flow to the flowtable, and increment routed_orig. The existing routed_repl rule on veth0 already handles the reply direction since decapsulated reply packets exit through the physical interface. Also add check_counters() for the IP6IP6 non-VLAN and IP6IP6-over-VLAN tests which previously used a bare PASS message. Fixes: |

The kselftests doc mentions that a config file should be present "if a

requires some kernel config, but no config file was provided.
We could say that a sub-target could use the parent's config file, but
the kselftests doc doesn't mention anything about that. Plus the
net/openvswitch target is the only net target without a config file.
Here is a new config file, which is a trimmed version of the net one,

selftests/fuse: add ACL_DONT_CACHE regression test
Add a test that reproduces the stale ACL bug fixed by:
"fs: preserve ACL_DONT_CACHE state in forget_cached_acl()"
A FUSE mount that does not negotiate FUSE_POSIX_ACL initialises inodes
with i_acl = ACL_DONT_CACHE. Before the fix, calling
forget_all_cached_acls() (e.g. from fuse_update_get_attr() on a
statx(AT_STATX_FORCE_SYNC)) would silently replace ACL_DONT_CACHE with
ACL_NOT_CACHED, enabling the kernel ACL cache. A subsequent getxattr
would populate the cache, and because fuse_set_acl() skips
forget_all_cached_acls() for !fc->posix_acl, later ACL changes were
not visible to callers — getxattr returned stale data.
The test mounts a minimal libfuse3 lowlevel filesystem (no
FUSE_POSIX_ACL negotiated) and:
1. Issues two getxattrs — both must reach the daemon, proving
ACL_DONT_CACHE suppresses caching before any trigger.
2. Calls statx(AT_STATX_FORCE_SYNC) to trigger forget_all_cached_acls().
3. Issues another getxattr (populates the cache on a buggy kernel).
4. Switches the daemon to a different-sized ACL (ACL_B).
5. Issues a final getxattr — expects ACL_B (44 bytes) and daemon
call count 4; a buggy kernel returns stale ACL_A (28 bytes).
fuse_acl_cache_test is only built when libfuse3 is detected via
pkg-config.
Christian Brauner <brauner@kernel.org> says:
Changed do_force_statx() to call the statx() libc wrapper instead of
syscall(SYS_statx, ...) as requested by Amir after review feedback from
Luis Henriques, and dropped the now unused <sys/syscall.h> include.

KVM: selftests: sev_init2_tests: Derive SEV availability from KVM
The test asserted that the X86_FEATURE_SEV CPUID bit exactly matches whether KVM offers KVM_X86_SEV_VM. That is not an invariant: when all SEV ASIDs are assigned to SEV-SNP, KVM does not offer the SEV VM type even though CPUID reports SEV, so the test aborts on an SNP-only host. Derive SEV availability from KVM_CAP_VM_TYPES (as already done for SEV-ES and SNP), assert only the one-way implication that a type offered by KVM is also reported in CPUID, and TEST_REQUIRE() the SEV VM type so the test skips cleanly when it is unavailable.

sev_smoke_test ran the plain SEV subtest unconditionally, gated only on the X86_FEATURE_SEV CPUID bit, while gating SEV-ES and SNP on the KVM_CAP_VM_TYPES bits. CPUID reporting SEV does not mean KVM offers the SEV VM type: when all SEV ASIDs are assigned to SEV-SNP, KVM_X86_SEV_VM is unavailable even though X86_FEATURE_SEV is set. On such a host the test aborts in KVM_CREATE_VM instead of exercising the available modes.

selftests/net: Fix tun IPv6 test addresses to avoid 6to4 range
The IPv6 addresses used for the tun_vnet_udptnl fixture currently fall in
the 2002::/16 prefix, which is reserved for the 6to4 transition mechanism
(RFC 3056).
On systems where the sit module is loaded, the kernel automatically claims
2002::/16 as a 6to4 tunnel prefix. When the test assigns a 2002:: address
to a TUN interface, sit registers a competing local route for the same
address. This ambiguity breaks the GENEVE decapsulation path: packets
injected via the TUN fd are not delivered to the test socket, causing the
IPv6-outer gtgso send_gso_packet variants to fail.
Replace all four IPv6 test addresses with addresses from the fd00:db8::/32
range, which is part of the ULA space (fc00::/7, RFC 4193) and carries no
special kernel semantics.

fs/proc/task_mmu: fix PAGEMAP_SCAN written state for unpopulated ptes
PAGEMAP_SCAN reports an unpopulated pte differently depending on which
path serves the request. The PAGE_IS_WRITTEN fast path in
pagemap_scan_pmd_entry() reports a pte_none as written (and, under
PM_SCAN_WP_MATCHING, arms a marker); pagemap_page_category() returns 0 for
the same pte_none. A request that cannot take the fast path (an extra
category bit, category_anyof_mask or category_inverted) therefore reports
the pte as clean and skips arming it.
A range that was populated and then MADV_DONTNEED'd reads as written via
one mask and clean via another, and in the latter case is not re-armed for
the next round -- an incremental-dump consumer (e.g. CRIU) using a richer
mask drops the zapped range and stops tracking writes to it.
Report pte_none as written in pagemap_page_category() too. A pte_none
carries no uffd-wp marker, i.e. it is not write-protected -- the same
condition under which the present and swap cases already report
PAGE_IS_WRITTEN. The fast path applies no VMA test, so neither does this.
The hugetlb and fully-unpopulated-PMD (no page table) scans have no
PAGE_IS_WRITTEN fast path, so they do not exhibit the per-entry divergence
and are left unchanged.
Add a pagemap_ioctl selftest that populates a range, drops it with
MADV_DONTNEED, and checks that the fast path and the generic
(category_anyof_mask) path both report every page written.

selftests/net: ovpn: fix getaddrinfo memory leak in ovpn_parse_remote()
The ovpn_parse_remote() function has two memory management issues:
1. When both 'host' and 'vpnip' are non-NULL, the first getaddrinfo()
allocation is leaked because 'result' is overwritten by the second
getaddrinfo() call without freeing the first allocation.
2. When both 'host' and 'vpnip' are NULL, 'result' is an uninitialized
stack variable passed to freeaddrinfo(), which is undefined behavior.
Fix by initializing 'result' to NULL and calling freeaddrinfo() after
the first getaddrinfo() result is consumed.

selftests: ntsync: correct CONFIG_NTSYNC name
The config fragment for these tests defines CONFIG_WINESYNC, which
refers to an earlier name for the ntsync driver before it was merged
[1]. Correct it to define CONFIG_NTSYNC instead.

selftests: netconsole: only restore MAC when it changed on resume
The "mac" bind mode reactivation downs the interface, restores the saved
MAC and renames it to trigger a target resume. This assumes the recreated
interface comes back with a different MAC, which is true under
MACAddressPolicy=none (as on the Netdev CI) but not when MACs are
persistent. In the persistent case netconsole resumes the target on its
own, and the down/restore/rename flow instead drops it and fails the test.
Guard the block on the MAC having actually changed so the test passes
under both policies.

selftests/bpf: Cover tracing implicit kfunc args
KF_IMPLICIT_ARGS kfuncs have a BPF-call prototype and a real kernel target prototype. Add a tracing selftest that attaches fentry and fexit programs to bpf_kfunc_implicit_arg(), runs a syscall BPF program that calls it, and checks that the tracing context exposes both the explicit argument and the implicit prog aux pointer.
