2023-12-09GPIO descriptor cleanup for some Wolfson codecsMark Brown5-39/+0
Merge series from Linus Walleij <linus.walleij@linaro.org>: This converts the remaining Wolfson ASoC codecs to use GPIO descriptors. These Wolfson codecs are mostly used with different Samsung S3C (especially Cragganmore 6410) board files, so the in-tree users are fixed up in the process.
2023-12-08ASoC: wm8996: Convert to GPIO descriptorsLinus Walleij1-3/+0
This converts the WM8996 codec to use GPIO descriptors, an a similar way to WM5100. The driver is instantiating a GPIO chip named wm8996, and we get rid of the base address for the GPIO chip from the platform data and just use dynamic numbering. Move base and ngpio into the static gpio_chip template. Fix up the only in-tree user which is the Cragganmore 6410 module.

2023-12-08ASoC: wm5100: Convert to GPIO descriptorsLinus Walleij1-4/+0
This converts the WM5100 codec to use GPIO descriptors, a pretty straight-forward conversion with the following peculiarities: - The driver is instantiating a GPIO chip named wm5100, and the headphone polarity detection GPIO is lifted from there. We add this to the GPIO descriptor table as well, and we can then get rid of also the base address for the GPIO chip from the platform data and just use dynamic numbering. - Fix up the only in-tree user which is the Cragganmore 6410 module.

2023-12-08ASoC: wm2200: Convert to GPIO descriptorsLinus Walleij1-2/+0
This converts the WM2200 codec to use GPIO descriptors. This is a pretty straight-forward conversion, and it also switches over the single in-tree user in the S3C Cragganmore module for S3C 6410. This coded does not seem to get selected or be selectable through Kconfig, I had to hack another soundcard Kconfig entry to select it for compile tests.

2023-12-08ASoC: wm1250-ev1: Convert to GPIO descriptorsLinus Walleij1-24/+0
This converts the WM1250-EV1 codec to use GPIO descriptors. It turns out that the platform data was only used to pass some global GPIO numbers from a board file, so we get rid of this and also switch over the single in-tree user in the S3C Cragganmore module for S3C 6410. The driver obtains two GPIO lines named OSR and master and just pull them low, we leave this behaviour as it was.

By this patch, not only N:M connection, but all existing connection (1:1, 1:N, N:N) will use same connection mapping. Then, because it will use default mapping, no conversion patch is needed to exising drivers.

git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs Pull vfs fixes from Christian Brauner: - Avoid calling back into LSMs from vfs_getattr_nosec() calls. IMA used to query inode properties accessing raw inode fields without dedicated helpers. That was finally fixed a few releases ago by forcing IMA to use vfs_getattr_nosec() helpers. The goal of the vfs_getattr_nosec() helper is to query for attributes without calling into the LSM layer which would be quite problematic because incredibly IMA is called from __fput()... __fput() -> ima_file_free() What it does is to call back into the filesystem to update the file's IMA xattr. Querying the inode without using vfs_getattr_nosec() meant that IMA didn't handle stacking filesystems such as overlayfs correctly. So the switch to vfs_getattr_nosec() is quite correct. But the switch to vfs_getattr_nosec() revealed another bug when used on stacking filesystems: __fput() -> ima_file_free() -> vfs_getattr_nosec() -> i_op->getattr::ovl_getattr() -> vfs_getattr() -> i_op->getattr::$WHATEVER_UNDERLYING_FS_getattr() -> security_inode_getattr() # calls back into LSMs Now, if that __fput() happens from task_work_run() of an exiting task current->fs and various other pointer could already be NULL. So anything in the LSM layer relying on that not being NULL would be quite surprised. Fix that by passing the information that this is a security request through to the stacking filesystem by adding a new internal ATT_GETATTR_NOSEC flag. Now the callchain becomes: __fput() -> ima_file_free() -> vfs_getattr_nosec() -> i_op->getattr::ovl_getattr() -> if (AT_GETATTR_NOSEC) vfs_getattr_nosec() else vfs_getattr() -> i_op->getattr::$WHATEVER_UNDERLYING_FS_getattr() - Fix a bug introduced with the iov_iter rework from last cycle. This broke /proc/kcore by copying too much and without the correct offset. - Add a missing NULL check when allocating the root inode in autofs_fill_super(). - Fix stable writes for multi-device filesystems (xfs, btrfs etc) and the block device pseudo filesystem. Stable writes used to be a superblock flag only, making it a per filesystem property. Add an additional AS_STABLE_WRITES mapping flag to allow for fine-grained control. - Ensure that offset_iterate_dir() returns 0 after reaching the end of a directory so it adheres to getdents() convention. * tag 'vfs-6.7-rc3.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: libfs: getdents() should return 0 after reaching EOD xfs: respect the stable writes flag on the RT device xfs: clean up FS_XFLAG_REALTIME handling in xfs_ioctl_setattr_xflags block: update the stable_writes flag in bdev_add filemap: add a per-mapping stable writes flag autofs: add: new_inode check in autofs_fill_super() iov_iter: fix copy_page_to_iter_nofault() fs: Pass AT_GETATTR_NOSEC flag to getattr interface function

2023-11-22asm-generic: qspinlock: fix queued_spin_value_unlocked() implementationLinus Torvalds1-1/+1
We really don't want to do atomic_read() or anything like that, since we already have the value, not the lock. The whole point of this is that we've loaded the lock from memory, and we want to check whether the value we loaded was a locked one or not. The main use of this is the lockref code, which loads both the lock and the reference count in one atomic operation, and then works on that combined value. With the atomic_read(), the compiler would pointlessly spill the value to the stack, in order to then be able to read it back "atomically". This is the qspinlock version of commit c6f4a9002252 ("asm-generic: ticket-lock: Optimize arch_spin_value_unlocked()") which fixed this same bug for ticket locks.

2023-11-21bpf: keep track of max number of bpf_loop callback iterationsEduard Zingerman1-0/+11
In some cases verifier can't infer convergence of the bpf_loop() iteration. E.g. for the following program: static int cb(__u32 idx, struct num_context* ctx) { ctx->i++; return 0; } SEC("?raw_tp") int prog(void *_) { struct num_context ctx = { .i = 0 }; __u8 choice_arr[2] = { 0, 1 }; bpf_loop(2, cb, &ctx, 0); return choice_arr[ctx.i]; } Each 'cb' simulation would eventually return to 'prog' and reach 'return choice_arr[ctx.i]' statement. At which point ctx.i would be marked precise, thus forcing verifier to track multitude of separate states with {.i=0}, {.i=1}, ... at bpf_loop() callback entry. This commit allows "brute force" handling for such cases by limiting number of callback body simulations using 'umax' value of the first bpf_loop() parameter. For this, extend bpf_func_state with 'callback_depth' field. Increment this field when callback visiting state is pushed to states traversal stack. For frame #N it's 'callback_depth' field counts how many times callback with frame depth N+1 had been executed. Use bpf_func_state specifically to allow independent tracking of callback depths when multiple nested bpf_loop() calls are present.

2023-11-21bpf: verify callbacks as if they are called unknown number of timesEduard Zingerman1-0/+5
Prior to this patch callbacks were handled as regular function calls, execution of callback body was modeled exactly once. This patch updates callbacks handling logic as follows: - introduces a function push_callback_call() that schedules callback body verification in env->head stack; - updates prepare_func_exit() to reschedule callback body verification upon BPF_EXIT; - as calls to bpf_*_iter_next(), calls to callback invoking functions are marked as checkpoints; - is_state_visited() is updated to stop callback based iteration when some identical parent state is found. Paths with callback function invoked zero times are now verified first, which leads to necessity to modify some selftests: - the following negative tests required adding release/unlock/drop calls to avoid previously masked unrelated error reports: - cb_refs.c:underflow_prog - exceptions_fail.c:reject_rbtree_add_throw - exceptions_fail.c:reject_with_cp_reference - the following precision tracking selftests needed change in expected log trace: - verifier_subprog_precision.c:callback_result_precise (note: r0 precision is no longer propagated inside callback and I think this is a correct behavior) - verifier_subprog_precision.c:parent_callee_saved_reg_precise_with_callback - verifier_subprog_precision.c:parent_stack_slot_precise_with_callback Reported-by: Andrew Werner <awerner32@gmail.com> Closes: https://lore.kernel.org/bpf/CA+vRuzPChFNXmouzGG+wsy=6eMcfr1mFG0F3g7rbg-sedGKW3w@mail.gmail.com/ Acked-by: Andrii Nakryiko <andrii@kernel.org> Signed-off-by: Eduard Zingerman <eddyz87@gmail.com> Link: https://lore.kernel.org/r/20231121020701.26440-7-eddyz87@gmail.com Signed-off-by: Alexei Starovoitov <ast@kernel.org>

2023-11-20filemap: add a per-mapping stable writes flagChristoph Hellwig1-0/+17
folio_wait_stable waits for writeback to finish before modifying the contents of a folio again, e.g. to support check summing of the data in the block integrity code. Currently this behavior is controlled by the SB_I_STABLE_WRITES flag on the super_block, which means it is uniform for the entire file system. This is wrong for the block device pseudofs which is shared by all block devices, or file systems that can use multiple devices like XFS witht the RT subvolume or btrfs (although btrfs currently reimplements folio_wait_stable anyway). Add a per-address_space AS_STABLE_WRITES flag to control the behavior in a more fine grained way. The existing SB_I_STABLE_WRITES is kept to initialize AS_STABLE_WRITES to the existing default which covers most cases.

2023-11-18fs: Pass AT_GETATTR_NOSEC flag to getattr interface functionStefan Berger1-0/+3
When vfs_getattr_nosec() calls a filesystem's getattr interface function then the 'nosec' should propagate into this function so that vfs_getattr_nosec() can again be called from the filesystem's gettattr rather than vfs_getattr(). The latter would add unnecessary security checks that the initial vfs_getattr_nosec() call wanted to avoid. Therefore, introduce the getattr flag GETATTR_NOSEC and allow to pass with the new getattr_flags parameter to the getattr interface function. In overlayfs and ecryptfs use this flag to determine which one of the two functions to call. In a recent code change introduced to IMA vfs_getattr_nosec() ended up calling vfs_getattr() in overlayfs, which in turn called security_inode_getattr() on an exiting process that did not have current->fs set anymore, which then caused a kernel NULL pointer dereference. With this change the call to security_inode_getattr() can be avoided, thus avoiding the NULL pointer dereference.

2023-11-16net: sched: do not offload flows with a helper in act_ctXin Long1-0/+9
There is no hardware supporting ct helper offload. However, prior to this patch, a flower filter with a helper in the ct action can be successfully set into the HW, for example (eth1 is a bnxt NIC): # tc qdisc add dev eth1 ingress_block 22 ingress # tc filter add block 22 proto ip flower skip_sw ip_proto tcp \ dst_port 21 ct_state -trk action ct helper ipv4-tcp-ftp # tc filter show dev eth1 ingress filter block 22 protocol ip pref 49152 flower chain 0 handle 0x1 eth_type ipv4 ip_proto tcp dst_port 21 ct_state -trk skip_sw in_hw in_hw_count 1 <---- action order 1: ct zone 0 helper ipv4-tcp-ftp pipe index 2 ref 1 bind 1 used_hw_stats delayed This might cause the flower filter not to work as expected in the HW. This patch avoids this problem by simply returning -EOPNOTSUPP in tcf_ct_offload_act_setup() to not allow to offload flows with a helper in act_ct.

2023-11-15bpf: Do not allocate percpu memory at init stageYonghong Song1-1/+1
Kirill Shutemov reported significant percpu memory consumption increase after booting in 288-cpu VM ([1]) due to commit 41a5db8d8161 ("bpf: Add support for non-fix-size percpu mem allocation"). The percpu memory consumption is increased from 111MB to 969MB. The number is from /proc/meminfo. I tried to reproduce the issue with my local VM which at most supports upto 255 cpus. With 252 cpus, without the above commit, the percpu memory consumption immediately after boot is 57MB while with the above commit the percpu memory consumption is 231MB. This is not good since so far percpu memory from bpf memory allocator is not widely used yet. Let us change pre-allocation in init stage to on-demand allocation when verifier detects there is a need of percpu memory for bpf program. With this change, percpu memory consumption after boot can be reduced signicantly.

2023-11-14netfilter: nf_tables: fix pointer math issue in nft_byteorder_eval()Dan Carpenter1-2/+2
The problem is in nft_byteorder_eval() where we are iterating through a loop and writing to dst[0], dst[1], dst[2] and so on... On each iteration we are writing 8 bytes. But dst[] is an array of u32 so each element only has space for 4 bytes. That means that every iteration overwrites part of the previous element. I spotted this bug while reviewing commit caf3ef7468f7 ("netfilter: nf_tables: prevent OOB access in nft_byteorder_eval") which is a related issue. I think that the reason we have not detected this bug in testing is that most of time we only write one element.

2023-11-14xen/events: reduce externally visible helper functionsJuergen Gross1-2/+2
get_evtchn_to_irq() has only one external user while irq_from_evtchn() provides the same functionality and is exported for a wider user base. Modify the only external user of get_evtchn_to_irq() to use irq_from_evtchn() instead and make get_evtchn_to_irq() static. evtchn_from_irq() and irq_from_virq() have a single external user and can easily be combined to a new helper irq_evtchn_from_virq() allowing to drop irq_from_virq() and to make evtchn_from_irq() static.
