2021-07-17platform/x86: think-lmi: Move pending_reboot_attr to the attributes sysfs dirMark Pearson
Move the pending_reboot node under attributes dir where it should live, as documented in: Documentation/ABI/testing/sysfs-class-firmware-attributes. Also move the create / remove code to be together with the other code populating / cleaning the attributes sysfs dir. In the removal path this is necessary so that the remove is done before the kset_unregister(tlmi_priv.attribute_kset) call.

2021-07-17ALSA: sb: Fix potential ABBA deadlock in CSP driverTakashi Iwai
SB16 CSP driver may hit potentially a typical ABBA deadlock in two code paths: In snd_sb_csp_stop(): spin_lock_irqsave(&p->chip->mixer_lock, flags); spin_lock(&p->chip->reg_lock); In snd_sb_csp_load(): spin_lock_irqsave(&p->chip->reg_lock, flags); spin_lock(&p->chip->mixer_lock); Also the similar pattern is seen in snd_sb_csp_start(). Although the practical impact is very small (those states aren't triggered in the same running state and this happens only on a real hardware, decades old ISA sound boards -- which must be very difficult to find nowadays), it's a real scenario and has to be fixed. This patch addresses those deadlocks by splitting the locks in snd_sb_csp_start() and snd_sb_csp_stop() for avoiding the nested locks.

Ronak Doshi says: ==================== vmxnet3: upgrade to version 6 vmxnet3 emulation has recently added several new features which includes increase in queues supported, remove power of 2 limitation on queues, add RSS for ESP IPv6, etc. This patch series extends the vmxnet3 driver to leverage these new features. Compatibility is maintained using existing vmxnet3 versioning mechanism as follows: - new features added to vmxnet3 emulation are associated with new vmxnet3 version viz. vmxnet3 version 6. - emulation advertises all the versions it supports to the driver. - during initialization, vmxnet3 driver picks the highest version number supported by both the emulation and the driver and configures emulation to run at that version. In particular, following changes are introduced: Patch 1: This patch introduces utility macros for vmxnet3 version 6 comparison and updates Copyright information. Patch 2: This patch adds support to increase maximum Tx/Rx queues from 8 to 32. Patch 3: This patch removes the limitation of power of 2 on the queues. Patch 4: Uses existing get_rss_hash_opts and set_rss_hash_opts methods to add support for ESP IPv6 RSS. Patch 5: This patch reports correct RSS hash type based on the type of RSS performed. Patch 6: This patch updates maximum configurable mtu to 9190. Patch 7: With all vmxnet3 version 6 changes incorporated in the vmxnet3 driver, with this patch, the driver can configure emulation to run at vmxnet3 version 6. ==================== Signed-off-by: David S.

2021-07-16tipc: keep the skb in rcv queue until the whole data is readXin Long
Currently, when userspace reads a datagram with a buffer that is smaller than this datagram, the data will be truncated and only part of it can be received by users. It doesn't seem right that users don't know the datagram size and have to use a huge buffer to read it to avoid the truncation. This patch to fix it by keeping the skb in rcv queue until the whole data is read by users. Only the last msg of the datagram will be marked with MSG_EOR, just as TCP/SCTP does. Note that this will work as above only when MSG_EOR is set in the flags parameter of recvmsg(), so that it won't break any old user applications.

As the name implies, Flex Filters are more flexible than using Layer-2, VLAN or MAC address filters, one of the reasons is that they allow "AND" operations more easily, e.g. when the user wants to steer some traffic based on the source MAC address and the packet ethertype. Future work include adding support for offloading tc-u32 filters to the hardware. The series is divided as follows: Patch 1/5, add the low level primitives for configuring Flex filters. Patch 2/5 and 3/5, allow ethtool to manage Flex filters. Patch 4/5, when specifying filters that have multiple predicates, use Flex filters.

2021-07-16libbpf: Clarify/fix unaligned data issues for btf typed dumpAlan Maguire
If data is packed, data structures can store it outside of usual boundaries. For example a 4-byte int can be stored on a unaligned boundary in a case like this: struct s { char f1; int f2; } __attribute((packed)); ...the int is stored at an offset of one byte. Some platforms have problems dereferencing data that is not aligned with its size, and code exists to handle most cases of this for BTF typed data display. However pointer display was missed, and a simple function to test if "ptr_is_aligned(data, data_sz)" would help clarify this code.

2021-07-16Merge branch 'libbpf: BTF dumper support for typed data'Andrii Nakryiko
Alan Maguire says: ==================== Add a libbpf dumper function that supports dumping a representation of data passed in using the BTF id associated with the data in a manner similar to the bpf_snprintf_btf helper. Default output format is identical to that dumped by bpf_snprintf_btf() (bar using tabs instead of spaces for indentation, but the indent string can be customized also); for example, a "struct sk_buff" representation would look like this: (struct sk_buff){ (union){ (struct){ .next = (struct sk_buff *)0xffffffffffffffff, .prev = (struct sk_buff *)0xffffffffffffffff, (union){ .dev = (struct net_device *)0xffffffffffffffff, .dev_scratch = (long unsigned int)18446744073709551615, }, }, ... Patch 1 implements the dump functionality in a manner similar to that in kernel/bpf/btf.c, but with a view to fitting into libbpf more naturally. For example, rather than using flags, boolean dump options are used to control output. In addition, rather than combining checks for display (such as is this field zero?) and actual display - as is done for the kernel code - the code is organized to separate zero and overflow checks from type display. Patch 2 adds ASSERT_STRNEQ() for use in the following BTF dumper tests. Patch 3 consists of selftests that utilize a dump printf function to snprintf the dump output to a string for comparison with expected output. Tests deliberately mirror those in snprintf_btf helper test to keep output consistent, but also cover overflow handling, var/section display. Changes since v5 [1] - readjust dump options to avoid unnecessary padding (Andrii, patch 1). - tidied up bitfield data checking/retrieval using Andrii's suggestions. Removed code where we adjust data pointer prior to calling bitfield functions as this adjustment is not needed, provided we use the type size as the number of bytes to iterate over when retrieving the full value we apply bit shifting operations to retrieve the bitfield value. With these chances, the *_int_bits() functions were no longer needed (Andrii, patch 1). - coalesced the "is zero" checking for ints, floats and pointers into btf_dump_base_type_check_zero(), using a memcmp() of the size of the data. This can be derived from t->size for ints and floats, and pointer size is retrieved from dump's ptr_sz field (Andrii, patch 1). - Added alignment-aware handling for int, enum, float retrieval. Packed data structures can force ints, enums and floats to be aligned on different boundaries; for example, the struct p { char f1; int f2; } __attribute__((packed)); ...will have the int f2 field offset at byte 1, rather than at byte 4 for an unpacked structure. The problem is directly dereferencing that as an int is problematic on some platforms. For ints and enums, we can reuse bitfield retrieval to get the value for display, while for floats we use a local union of the floating-point types and memcpy into it, ensuring we can then dereference pointers into that union which will have safe alignment (Andrii, patch 1). - added comments to explain why we increment depth prior to displaying opening parens, and decrement it prior to displaying closing parens for structs, unions and arrays. The reason is that we don't want to have a trailing newline when displaying a type. The logic that handles this says "don't show a newline when the depth we're at is 0". For this to work for opening parens then we need to bump depth before showing opening parens + newline, and when we close out structure we need to show closing parens after reducing depth so that we don't append a newline to a top-level structure. So as a result we have struct foo {\n struct bar {\n }\n } - silently truncate provided indent string with strncat() if > 31 bytes (Andrii, patch 1). - fixed ASSERT_STRNEQ() macro to show only n bytes of string (Andrii, patch 2). - fixed strncat() of type data string to avoid stack corruption (Andrii, patch 3). - removed early returns from dump type tests (Andrii, patch 3). - have tests explicitly specify prefix (enum, struct, union) (Andrii, patch 3). - switch from CHECK() to ASSERT_* where possible (Andrii, patch 3). Changes since v4 [2] - Andrii kindly provided code to unify emitting a prepended cast (for example "(int)") with existing code, and this had the nice benefit of adding array indices in type specifications (Andrii, patches 1, 3) - Fixed indent_str option to make it a const char *, stored in a fixed-length buffer internally (Andrii, patch 1) - Reworked bit shift logic to minimize endian-specific interactions, and use same macros as found elsewhere in libbpf to determine endianness (Andrii, patch 1) - Fixed type emitting to ensure that a trailing '\n' is not displayed; newlines are added during struct/array display, but for a single type the last character is no longer a newline (Andrii, patches 1, 3) - Added support for ASSERT_STRNEQ() macro (Andrii, patch 2) - Split tests into subtests for int, char, enum etc rather than one "dump type data" subtest (Andrii, patch 3) - Made better use of ASSERT* macros (Andrii, patch 3) - Got rid of some other TEST_* macros that were unneeded (Andrii, patch 3) - Switched to using "struct fs_context" to verify enum bitfield values (Andrii, patch 3) Changes since v3 [3] - Retained separation of emitting of type name cast prefixing type values from existing functionality such as btf_dump_emit_type_chain() since initial code-shared version had so many exceptions it became hard to read. For example, we don't emit a type name if the type to be displayed is an array member, we also always emit "forward" definitions for structs/unions that aren't really forward definitions (we just want a "struct foo" output for "(struct foo){.bar = ...". We also always ignore modifiers const/volatile/restrict as they clutter output when emitting large types. - Added configurable 4-char indent string option; defaults to tab (Andrii) - Added support for BTF_KIND_FLOAT and associated tests (Andrii) - Added support for BTF_KIND_FUNC_PROTO function pointers to improve output of "ops" structures; for example: (struct file_operations){ .owner = (struct module *)0xffffffffffffffff, .llseek = (loff_t(*)(struct file *, loff_t, int))0xffffffffffffffff, ... Added associated test also (Andrii) - Added handling for enum bitfields and associated test (Andrii) - Allocation of "struct btf_dump_data" done on-demand (Andrii) - Removed ".field = " output from function emitting type name and into caller (Andrii) - Removed BTF_INT_OFFSET() support (Andrii) - Use libbpf_err() to set errno for error cases (Andrii) - btf_dump_dump_type_data() returns size written, which is used when returning successfully from btf_dump__dump_type_data() (Andrii) Changes since v2 [4] - Renamed function to btf_dump__dump_type_data, reorganized arguments such that opts are last (Andrii) - Modified code to separate questions about display such as have we overflowed?/is this field zero? from actual display of typed data, such that we ask those questions separately from the code that actually displays typed data (Andrii) - Reworked code to handle overflow - where we do not provide enough data for the type we wish to display - by returning -E2BIG and attempting to present as much data as possible. Such a mode of operation allows for tracers which retrieve partial data (such as first 1024 bytes of a "struct task_struct" say), and want to display that partial data, while also knowing that it is not the full type. Such tracers can then denote this (perhaps via "..." or similar). - Explored reusing existing type emit functions, such as passing in a type id stack with a single type id to btf_dump_emit_type_chain() to support the display of typed data where a "cast" is prepended to the data to denote its type; "(int)1", "(struct foo){", etc. However the task of emitting a ".field_name = (typecast)" did not match well with model of walking the stack to display innermost types first and made the resultant code harder to read. Added a dedicated btf_dump_emit_type_name() function instead which is only ~70 lines (Andrii) - Various cleanups around bitfield macros, unneeded member iteration macros, avoiding compiler complaints when displaying int da ta by casting to long long, etc (Andrii) - Use DECLARE_LIBBPF_OPTS() in defining opts for tests (Andrii) - Added more type tests, overflow tests, var tests and section tests. Changes since RFC [5] - The initial approach explored was to share the kernel code with libbpf using #defines to paper over the different needs; however it makes more sense to try and fit in with libbpf code style for maintenance. A comment in the code points at the implementation in kernel/bpf/btf.c and notes that any issues found in it should be fixed there or vice versa; mirroring the tests should help with this also (Andrii) [1] https://lore.kernel.org/bpf/1624092968-5598-1-git-send-email-alan.maguire@oracle.com/ [2] https://lore.kernel.org/bpf/CAEf4BzYtbnphCkhz0epMKE4zWfvSOiMpu+-SXp9hadsrRApuZw@mail.gmail.com/T/ [3] https://lore.kernel.org/bpf/1622131170-8260-1-git-send-email-alan.maguire@oracle.com/ [4] https://lore.kernel.org/bpf/1610921764-7526-1-git-send-email-alan.maguire@oracle.com/ [5] https://lore.kernel.org/bpf/1610386373-24162-1-git-send-email-alan.maguire@oracle.com/ ==================== Signed-off-by: Andrii Nakryiko <andrii@kernel.org>

2021-07-16libbpf: BTF dumper support for typed dataAlan Maguire
Add a BTF dumper for typed data, so that the user can dump a typed version of the data provided. The API is int btf_dump__dump_type_data(struct btf_dump *d, __u32 id, void *data, size_t data_sz, const struct btf_dump_type_data_opts *opts); ...where the id is the BTF id of the data pointed to by the "void *" argument; for example the BTF id of "struct sk_buff" for a "struct skb *" data pointer. Options supported are - a starting indent level (indent_lvl) - a user-specified indent string which will be printed once per indent level; if NULL, tab is chosen but any string <= 32 chars can be provided. - a set of boolean options to control dump display, similar to those used for BPF helper bpf_snprintf_btf(). Options are - compact : omit newlines and other indentation - skip_names: omit member names - emit_zeroes: show zero-value members Default output format is identical to that dumped by bpf_snprintf_btf(), for example a "struct sk_buff" representation would look like this: struct sk_buff){ (union){ (struct){ .next = (struct sk_buff *)0xffffffffffffffff, .prev = (struct sk_buff *)0xffffffffffffffff, (union){ .dev = (struct net_device *)0xffffffffffffffff, .dev_scratch = (long unsigned int)18446744073709551615, }, }, ... If the data structure is larger than the *data_sz* number of bytes that are available in *data*, as much of the data as possible will be dumped and -E2BIG will be returned. This is useful as tracers will sometimes not be able to capture all of the data associated with a type; for example a "struct task_struct" is ~16k. Being able to specify that only a subset is available is important for such cases. On success, the amount of data dumped is returned.

2021-07-16mt7530 fix mt7530_fdb_write vid missing ivl bitEric Woudstra
According to reference guides mt7530 (mt7620) and mt7531: NOTE: When IVL is reset, MAC[47:0] and FID[2:0] will be used to read/write the address table. When IVL is set, MAC[47:0] and CVID[11:0] will be used to read/write the address table. Since the function only fills in CVID and no FID, we need to set the IVL bit. The existing code does not set it. This is a fix for the issue I dropped here earlier: http://lists.infradead.org/pipermail/linux-mediatek/2021-June/025697.html With this patch, it is now possible to delete the 'self' fdb entry manually. However, wifi roaming still has the same issue, the entry does not get deleted automatically. Wifi roaming also needs a fix somewhere else to function correctly in combination with vlan.
