2024-07-25net: mediatek: Fix potential NULL pointer dereference in dummy net_device ↵Breno Leitao
handling Move the freeing of the dummy net_device from mtk_free_dev() to mtk_remove(). Previously, if alloc_netdev_dummy() failed in mtk_probe(), eth->dummy_dev would be NULL. The error path would then call mtk_free_dev(), which in turn called free_netdev() assuming dummy_dev was allocated (but it was not), potentially causing a NULL pointer dereference. By moving free_netdev() to mtk_remove(), we ensure it's only called when mtk_probe() has succeeded and dummy_dev is fully allocated. This addresses a potential NULL pointer dereference detected by Smatch[1]. Fixes: b209bd6d0bff ("net: mediatek: mtk_eth_sock: allocate dummy net_device dynamically") Reported-by: Dan Carpenter <dan.carpenter@linaro.org> Closes: https://lore.kernel.org/all/4160f4e0-cbef-4a22-8b5d-42c4d399e1f7@stanley.mountain/ [1] Suggested-by: Dan Carpenter <dan.carpenter@linaro.org> Reviewed-by: Dan Carpenter <dan.carpenter@linaro.org> Signed-off-by: Breno Leitao <leitao@debian.org> Reviewed-by: Simon Horman <horms@kernel.org> Link: https://patch.msgid.link/20240724080524.2734499-1-leitao@debian.org Signed-off-by: Paolo Abeni <pabeni@redhat.com>

2024-07-24drm/amdgpu: reset vm state machine after gpu reset(vram lost)ZhenGuo Yin
[Why] Page table of compute VM in the VRAM will lost after gpu reset. VRAM won't be restored since compute VM has no shadows. [How] Use higher 32-bit of vm->generation to record a vram_lost_counter. Reset the VM state machine when vm->genertaion is not equal to the new generation token. v2: Check vm->generation instead of calling drm_sched_entity_error in amdgpu_vm_validate. v3: Use new generation token instead of vram_lost_counter for check.

2024-07-24sysctl: treewide: constify the ctl_table argument of proc_handlersJoel Granados
const qualify the struct ctl_table argument in the proc_handler function signatures. This is a prerequisite to moving the static ctl_table structs into .rodata data which will ensure that proc_handler function pointers cannot be modified. This patch has been generated by the following coccinelle script: ``` virtual patch @r1@ identifier ctl, write, buffer, lenp, ppos; identifier func !~ "appldata_(timer|interval)_handler|sched_(rt|rr)_handler|rds_tcp_skbuf_handler|proc_sctp_do_(hmac_alg|rto_min|rto_max|udp_port|alpha_beta|auth|probe_interval)"; @@ int func( - struct ctl_table *ctl + const struct ctl_table *ctl ,int write, void *buffer, size_t *lenp, loff_t *ppos); @r2@ identifier func, ctl, write, buffer, lenp, ppos; @@ int func( - struct ctl_table *ctl + const struct ctl_table *ctl ,int write, void *buffer, size_t *lenp, loff_t *ppos) { ... } @r3@ identifier func; @@ int func( - struct ctl_table * + const struct ctl_table * ,int , void *, size_t *, loff_t *); @r4@ identifier func, ctl; @@ int func( - struct ctl_table *ctl + const struct ctl_table *ctl ,int , void *, size_t *, loff_t *); @r5@ identifier func, write, buffer, lenp, ppos; @@ int func( - struct ctl_table * + const struct ctl_table * ,int write, void *buffer, size_t *lenp, loff_t *ppos); ``` * Code formatting was adjusted in xfs_sysctl.c to comply with code conventions. The xfs_stats_clear_proc_handler, xfs_panic_mask_proc_handler and xfs_deprecated_dointvec_minmax where adjusted. * The ctl_table argument in proc_watchdog_common was const qualified. This is called from a proc_handler itself and is calling back into another proc_handler, making it necessary to change it as part of the proc_handler migration.

Commit 7572fea31e3e ("apparmor: convert fperm lookup to use accept as an index") made the verification check more rigourous regressing old userspaces with the bug. For compatibility reasons allow the orphaned transition table during unpack and discard.

2024-07-24apparmor: try to avoid refing the label in apparmor_file_openMateusz Guzik
If the label is not stale (which is the common case), the fact that the passed file object holds a reference can be leverged to avoid the ref/unref cycle. Doing so reduces performance impact of apparmor on parallel open() invocations.

However, we started counting one id too late and thus lost 4294967296 as the first valid id. Fix that. - Update a few comments on some vfs_*() creation helpers. - Move copying of the xattr name out from the locks required to start a filesystem write. - Extend the filelock lock UAF fix to the compat code as well. - Now that we added the ability to look up an inode under RCU it's possible that lockless hash lookup can find and lock an inode after it gets I_FREEING set. It then waits until inode teardown in evict() is finished. The flag however is still set after evict() has woken up all waiters. If the inode lock is taken late enough on the waiting side after hash removal and wakeup happened the waiting thread will never be woken. Before RCU based lookup this was synchronized via the inode_hash_lock. But since unhashing requires the inode lock as well we can check whether the inode is unhashed while holding inode lock even without holding inode_hash_lock. pidfd: - The nsproxy structure contains nearly all of the namespaces associated with a task. When a namespace type isn't supported nsproxy might contain a NULL pointer or always point to the initial namespace type. The logic isn't consistent. So when deriving namespace fds we need to ensure that the namespace type is supported. First, so that we don't risk dereferncing NULL pointers. The correct bigger fix would be to change all namespaces to always set a valid namespace pointer in struct nsproxy independent of whether or not it is compiled in. But that requires quite a few changes. Second, so that we don't allow deriving namespace fds when the namespace type doesn't exist and thus when they couldn't also be derived via /proc/self/ns/. - Add missing selftests for the new pidfd ioctls to derive namespace fds. This simply extends the already existing testsuite. netfs: - Fix debug logging and fix kconfig variable name so it actually works. - Fix writeback that goes both to the server and cache. The streams are only activated once a subreq is added. When a server write happens the subreq doesn't need to have finished by the time the cache write is started. If the server write has already finished by the time the cache write is about to start the cache write will operate on a folio that might already have been reused.

2024-07-24hostfs: fix folio conversionLinus Torvalds
Commit e3ec0fe944d2 ("hostfs: Convert hostfs_read_folio() to use a folio") simplified hostfs_read_folio(), but in the process of converting to using folios natively also mis-used the folio_zero_tail() function due to the very confusing API of that function. Very arguably it's folio_zero_tail() API itself that is buggy, since it would make more sense (and the documentation kind of implies) that the third argument would be the pointer to the beginning of the folio buffer. But no, the third argument to folio_zero_tail() is where we should start zeroing the tail (even if we already also pass in the offset separately as the second argument). So fix the hostfs caller, and we can leave any folio_zero_tail() sanity cleanup for later.

2024-07-24landlock: Don't lose track of restrictions on cred_transferJann Horn
When a process' cred struct is replaced, this _almost_ always invokes the cred_prepare LSM hook; but in one special case (when KEYCTL_SESSION_TO_PARENT updates the parent's credentials), the cred_transfer LSM hook is used instead. Landlock only implements the cred_prepare hook, not cred_transfer, so KEYCTL_SESSION_TO_PARENT causes all information on Landlock restrictions to be lost. This basically means that a process with the ability to use the fork() and keyctl() syscalls can get rid of all Landlock restrictions on itself. Fix it by adding a cred_transfer hook that does the same thing as the existing cred_prepare hook. (Implemented by having hook_cred_prepare() call hook_cred_transfer() so that the two functions are less likely to accidentally diverge in the future.)

The perfect_match parameter of the update_vlan_hash operation is __le16, and is correctly converted from host byte-order in the lone caller, stmmac_vlan_update(). However, the implementations of this caller, dwxgmac2_update_vlan_hash() and dwxgmac2_update_vlan_hash(), both treat this parameter as host byte order, using the following pattern: u32 value = ... ... writel(value | perfect_match, ...); This is not correct because both: 1) value is host byte order; and 2) writel expects a host byte order value as it's first argument I believe that this will break on big endian systems. And I expect it has gone unnoticed by only being exercised on little endian systems. The approach taken by this patch is to update the callback, and it's caller to simply use a host byte order value.

2024-07-24io_uring: tighten task exit cancellationsPavel Begunkov
io_uring_cancel_generic() should retry if any state changes like a request is completed, however in case of a task exit it only goes for another loop and avoids schedule() if any tracked (i.e. REQ_F_INFLIGHT) request got completed. Let's assume we have a non-tracked request executing in iowq and a tracked request linked to it. Let's also assume io_uring_cancel_generic() fails to find and cancel the request, i.e. via io_run_local_work(), which may happen as io-wq has gaps. Next, the request logically completes, io-wq still hold a ref but queues it for completion via tw, which happens in io_uring_try_cancel_requests(). After, right before prepare_to_wait() io-wq puts the request, grabs the linked one and tries executes it, e.g. arms polling. Finally the cancellation loop calls prepare_to_wait(), there are no tw to run, no tracked request was completed, so the tctx_inflight() check passes and the task is put to indefinite sleep.

2024-07-24trace: riscv: Remove deprecated kprobe on ftrace supportJinjie Ruan
Since commit 7caa9765465f60 ("ftrace: riscv: move from REGS to ARGS"), kprobe on ftrace is not supported by riscv, because riscv's support for FTRACE_WITH_REGS has been replaced with support for FTRACE_WITH_ARGS, and KPROBES_ON_FTRACE will be supplanted by FPROBES. So remove the deprecated kprobe on ftrace support, which is misunderstood.
