https://git.linaro.org/people/jens.wiklander/linux-tee Pull TEE update from Jens Wiklander: "Remove get_kernel_pages() Vmalloc page support is removed from shm_get_kernel_pages() and the get_kernel_pages() call is replaced by calls to get_page(). With no remaining callers of get_kernel_pages() the function is removed" [ This looks like it's just some random 'tee' cleanup, but the bigger picture impetus for this is really to to to remove historical confusion with mixed use of kernel virtual addresses and 'struct page' pointers. Kernel virtual pointers in the vmalloc space is then particularly confusing - both for looking up a page pointer (when trying to then unify a "virtual address or page" interface) and _particularly_ when mixed with HIGHMEM support and the kmap*() family of remapping. This is particularly true with HIGHMEM getting much less test coverage with 32-bit architectures being increasingly legacy targets. So we actively wanted to remove get_kernel_pages() to make sure nobody else used it too, and thus the 'tee' part is "finally remove last user". See also commit 6647e76ab623 ("v4l2: don't fall back to follow_pfn() if pin_user_pages_fast() fails") for a totally different version of a conceptually similar "let's stop this confusion of different ways of referring to memory". - Linus ] * tag 'remove-get_kernel_pages-for-6.3' of https://git.linaro.org/people/jens.wiklander/linux-tee: mm: Remove get_kernel_pages() tee: Remove call to get_kernel_pages() tee: Remove vmalloc page support highmem: Enhance is_kmap_addr() to check kmap_local_page() mappings

2023-02-17nilfs2: fix underflow in second superblock position calculationsRyusuke Konishi3-1/+23
Macro NILFS_SB2_OFFSET_BYTES, which computes the position of the second superblock, underflows when the argument device size is less than 4096 bytes. Therefore, when using this macro, it is necessary to check in advance that the device size is not less than a lower limit, or at least that underflow does not occur. The current nilfs2 implementation lacks this check, causing out-of-bound block access when mounting devices smaller than 4096 bytes: I/O error, dev loop0, sector 36028797018963960 op 0x0:(READ) flags 0x0 phys_seg 1 prio class 2 NILFS (loop0): unable to read secondary superblock (blocksize = 1024) In addition, when trying to resize the filesystem to a size below 4096 bytes, this underflow occurs in nilfs_resize_fs(), passing a huge number of segments to nilfs_sufile_resize(), corrupting parameters such as the number of segments in superblocks. This causes excessive loop iterations in nilfs_sufile_resize() during a subsequent resize ioctl, causing semaphore ns_segctor_sem to block for a long time and hang the writer thread: INFO: task segctord:5067 blocked for more than 143 seconds.

2023-02-17hugetlb: check for undefined shift on 32 bit architecturesMike Kravetz1-1/+4
Users can specify the hugetlb page size in the mmap, shmget and memfd_create system calls. This is done by using 6 bits within the flags argument to encode the base-2 logarithm of the desired page size. The routine hstate_sizelog() uses the log2 value to find the corresponding hugetlb hstate structure. Converting the log2 value (page_size_log) to potential hugetlb page size is the simple statement: 1UL << page_size_log Because only 6 bits are used for page_size_log, the left shift can not be greater than 63. This is fine on 64 bit architectures where a long is 64 bits. However, if a value greater than 31 is passed on a 32 bit architecture (where long is 32 bits) the shift will result in undefined behavior. This was generally not an issue as the result of the undefined shift had to exactly match hugetlb page size to proceed. Recent improvements in runtime checking have resulted in this undefined behavior throwing errors such as reported below. Fix by comparing page_size_log to BITS_PER_LONG before doing shift.

2023-02-17mm/migrate: fix wrongly apply write bit after mkdirty on sparc64Peter Xu2-2/+6
Nick Bowler reported another sparc64 breakage after the young/dirty persistent work for page migration (per "Link:" below). That's after a similar report [2]. It turns out page migration was overlooked, and it wasn't failing before because page migration was not enabled in the initial report test environment. David proposed another way [2] to fix this from sparc64 side, but that patch didn't land somehow. Neither did I check whether there's any other arch that has similar issues. Let's fix it for now as simple as moving the write bit handling to be after dirty, like what we did before. Note: this is based on mm-unstable, because the breakage was since 6.1 and we're at a very late stage of 6.2 (-rc8), so I assume for this specific case we should target this at 6.3.

2023-02-16mm/MADV_COLLAPSE: set EAGAIN on unexpected page refcountZach O'Keefe1-0/+1
During collapse, in a few places we check to see if a given small page has any unaccounted references. If the refcount on the page doesn't match our expectations, it must be there is an unknown user concurrently interested in the page, and so it's not safe to move the contents elsewhere. However, the unaccounted pins are likely an ephemeral state. In this situation, MADV_COLLAPSE returns -EINVAL when it should return -EAGAIN. This could cause userspace to conclude that the syscall failed, when it in fact could succeed by retrying.

2023-02-16mm/filemap: fix page end in filemap_get_read_batchQian Yingjin1-2/+3
I was running traces of the read code against an RAID storage system to understand why read requests were being misaligned against the underlying RAID strips. I found that the page end offset calculation in filemap_get_read_batch() was off by one. When a read is submitted with end offset 1048575, then it calculates the end page for read of 256 when it should be 255. "last_index" is the index of the page beyond the end of the read and it should be skipped when get a batch of pages for read in @filemap_get_read_batch(). The below simple patch fixes the problem. This code was introduced in kernel 5.12.

2023-02-16arm64: perf: reject CHAIN events at creation timeMark Rutland1-0/+8
Currently it's possible for a user to open CHAIN events arbitrarily, which we previously tried to rule out in commit: ca2b497253ad01c8 ("arm64: perf: Reject stand-alone CHAIN events for PMUv3") Which allowed the events to be opened, but prevented them from being scheduled by by using an arm_pmu::filter_match hook to reject the relevant events. The CHAIN event filtering in the arm_pmu::filter_match hook was silently removed in commit: bd27568117664b8b ("perf: Rewrite core context handling") As a result, it's now possible for users to open CHAIN events, and for these to be installed arbitrarily. Fix this by rejecting CHAIN events at creation time. This avoids the creation of events which will never count, and doesn't require using the dynamic filtering. Attempting to open a CHAIN event (0x1e) will now be rejected: | # ./perf stat -e armv8_pmuv3/config=0x1e/ ls | perf | | Performance counter stats for 'ls': | | <not supported> armv8_pmuv3/config=0x1e/ | | 0.002197470 seconds time elapsed | | 0.000000000 seconds user | 0.002294000 seconds sys Other events (e.g. CPU_CYCLES / 0x11) will open as usual: | # ./perf stat -e armv8_pmuv3/config=0x11/ ls | perf | | Performance counter stats for 'ls': | | 2538761 armv8_pmuv3/config=0x11/ | | 0.002227330 seconds time elapsed | | 0.002369000 seconds user | 0.000000000 seconds sys Fixes: bd2756811766 ("perf: Rewrite core context handling") Signed-off-by: Mark Rutland <mark.rutland@arm.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Ravi Bangoria <ravi.bangoria@amd.com> Cc: Will Deacon <will@kernel.org> Link: https://lore.kernel.org/r/20230216141240.3833272-3-mark.rutland@arm.com Signed-off-by: Will Deacon <will@kernel.org>
2023-02-16arm_pmu: fix event CPU filteringMark Rutland3-15/+1
Janne reports that perf has been broken on Apple M1 as of commit: bd27568117664b8b ("perf: Rewrite core context handling") That commit replaced the pmu::filter_match() callback with pmu::filter(), whose return value has the opposite polarity, with true implying events should be ignored rather than scheduled. While an attempt was made to update the logic in armv8pmu_filter() and armpmu_filter() accordingly, the return value remains inverted in a couple of cases: * If the arm_pmu does not have an arm_pmu::filter() callback, armpmu_filter() will always return whether the CPU is supported rather than whether the CPU is not supported. As a result, the perf core will not schedule events on supported CPUs, resulting in a loss of events. Additionally, the perf core will attempt to schedule events on unsupported CPUs, but this will be rejected by armpmu_add(), which may result in a loss of events from other PMUs on those unsupported CPUs. * If the arm_pmu does have an arm_pmu::filter() callback, and armpmu_filter() is called on a CPU which is not supported by the arm_pmu, armpmu_filter() will return false rather than true. As a result, the perf core will attempt to schedule events on unsupported CPUs, but this will be rejected by armpmu_add(), which may result in a loss of events from other PMUs on those unsupported CPUs. This means a loss of events can be seen with any arm_pmu driver, but with the ARMv8 PMUv3 driver (which is the only arm_pmu driver with an arm_pmu::filter() callback) the event loss will be more limited and may go unnoticed, which is how this issue evaded testing so far. Fix the CPU filtering by performing this consistently in armpmu_filter(), and remove the redundant arm_pmu::filter() callback and armv8pmu_filter() implementation. Commit bd2756811766 also silently removed the CHAIN event filtering from armv8pmu_filter(), which will be addressed by a separate patch without using the filter callback.

2023-02-16ASoC: SOF: Intel: hda-dai: fix possible stream_tag leakPierre-Louis Bossart1-4/+4
The HDaudio stream allocation is done first, and in a second step the LOSIDV parameter is programmed for the multi-link used by a codec. This leads to a possible stream_tag leak, e.g. if a DisplayAudio link is not used. This would happen when a non-Intel graphics card is used and userspace unconditionally uses the Intel Display Audio PCMs without checking if they are connected to a receiver with jack controls. We should first check that there is a valid multi-link entry to configure before allocating a stream_tag. This change aligns the dma_assign and dma_cleanup phases.

2023-02-16devlink: Fix netdev notifier chain corruptionIdo Schimmel3-14/+1
Cited commit changed devlink to register its netdev notifier block on the global netdev notifier chain instead of on the per network namespace one. However, when changing the network namespace of the devlink instance, devlink still tries to unregister its notifier block from the chain of the old namespace and register it on the chain of the new namespace. This results in corruption of the notifier chains, as the same notifier block is registered on two different chains: The global one and the per network namespace one. In turn, this causes other problems such as the inability to dismantle namespaces due to netdev reference count issues. Fix by preventing devlink from moving its notifier block between namespaces. Reproducer: # echo "10 1" > /sys/bus/netdevsim/new_device # ip netns add test123 # devlink dev reload netdevsim/netdevsim10 netns test123 # ip netns del test123 [ 71.935619] unregister_netdevice: waiting for lo to become free.

2023-02-15igb: conditionalize I2C bit banging on external thermal sensor supportCorinna Vinschen1-10/+32
Commit a97f8783a937 ("igb: unbreak I2C bit-banging on i350") introduced code to change I2C settings to bit banging unconditionally. However, this patch introduced a regression: On an Intel S2600CWR Server Board with three NICs: - 1x dual-port copper Intel I350 Gigabit Network Connection [8086:1521] (rev 01) fw 1.63, 0x80000dda - 2x quad-port SFP+ with copper SFP Avago ABCU-5700RZ Intel I350 Gigabit Fiber Network Connection [8086:1522] (rev 01) fw 1.52.0 the SFP NICs no longer get link at all. Reverting commit a97f8783a937 or switching to the Intel out-of-tree driver both fix the problem. Per the igb out-of-tree driver, I2C bit banging on i350 depends on support for an external thermal sensor (ETS). However, commit a97f8783a937 added bit banging unconditionally. Additionally, the out-of-tree driver always calls init_thermal_sensor_thresh on probe, while our driver only calls init_thermal_sensor_thresh only in igb_reset(), and only if an ETS is present, ignoring the internal thermal sensor. The affected SFPs don't provide an ETS. Per Intel, the behaviour is a result of i350 firmware requirements. This patch fixes the problem by aligning the behaviour to the out-of-tree driver: - split igb_init_i2c() into two functions: - igb_init_i2c() only performs the basic I2C initialization. - igb_set_i2c_bb() makes sure that E1000_CTRL_I2C_ENA is set and enables bit-banging. - igb_probe() only calls igb_set_i2c_bb() if an ETS is present. - igb_probe() calls init_thermal_sensor_thresh() unconditionally. - igb_reset() aligns its behaviour to igb_probe(), i. e., call igb_set_i2c_bb() if an ETS is present and call init_thermal_sensor_thresh() unconditionally.
