* ioctl: fix printing of ioctl numbers in -Xverbose modeEugene Syromyatnikov2021-10-121-4/+4
| | | | | | | | | | | When NULL is passed as dflt to printflags, nothing is printed at all if flags is 0. (Ab)use the fact that comment printing is not triggered for an empty string and pass "" instead of NULL. * src/ioctl.c (ioctl_print_code, evdev_decode_number, evdev_decode_number): Pass "" as dflt instead of NULL if abbrev is false. Fixes: v5.3~10 "ioctl: do not print comments twice in -Xverbose"
* util: handle QUOTE_0_TERMINATED|QUOTE_EXPECT_TRAILING_0 in printstr_exEugene Syromyatnikov2021-10-121-0/+6
| | | | | | | | | | | | | There is a number of places in kernel where the last character of a string-typed structure field is not fetched and/or overwritten with '\0'. So far, it was difficult to signify this in strace output done via printstr_ex; this commit adds logic that decreases size passed to print_quoted_string in order to signify that, while there is an additional non-NUL character in the field, it will be ignored by the kernel. * src/util.c (printstr_ex): Decrease size before print_quoted_string call if both QUOTE_0_TERMINATED and QUOTE_EXPECT_TRAILING_0 set.

While at it, print some additional information about the time spent. * tests/pidns-cache.c (SYSCALL_COUNT): Change from 1000 to 10000. (main): Store original run time in orig_us variable, print it along with the run time under the PID NS test harness in a message to stderr.

* io_uring: print struct io_cqring_offsets.flags as integer and not flagsEugene Syromyatnikov2021-10-123-10/+5
| | | | | | | | | | | | | Since this is the offset of the cq_flags field in struct io_rings and not the flags themselves. * src/xlat/uring_cqring_flags.in: Remove. * src/io_uring.c: Remove "xlat/uring_cqring_flags.h" include. (print_io_cqring_offsets): Print flags using PRINT_FIELD_U. * tests/io_uring_setup.c: Remove "xlat/uring_cqring_flags.h"; update expected output. Fixes: v5.8~57 "io_uring: Add io_cqring_offset flags"
* io_uring: cap io_uring_probe element count to nargs on exitingEugene Syromyatnikov2021-10-121-3/+5
| | | | | | | | | | | | While a sane kernel would set ops_len to a sane value, its tampering may lead to strace reading out of probe value bounds. While at it, set PAF_ARRAY_TRUNCATED in cases when nargs is less than probe->ops_len. * src/io_uring.c (print_io_uring_probe): Print minimum of nargs and probe->ops_len probe->ops array elements on exiting, set PAF_ARRAY_TRUNCATED flag if nargs is less than probe->ops_len. Fixes: v5.6~94 "io_uring: support IORING_REGISTER_PROBE io_uring_register command"
* util: print ellipsis inside an empty array if PAF_ARRAY_TRUNCATED is setEugene Syromyatnikov2021-10-121-0/+2

* affinity: print cpuset of len 0 as "[]"Eugene Syromyatnikov2021-10-122-1/+25
| | | | | | | | To be consistent with print_array_ex behaviour. * src/affinity.c (print_affinitylist): Handle "!len" and "!cpu" cases separately; print "[]" in the former. * tests/sched_xetaffinity.c: Add a check for a cpuset of size 0.
* affinity: use MIN and ROUNDUP macros in print_affinitylistEugene Syromyatnikov2021-10-121-3/+2

* xlat: no longer interpret NULL xlat as continuationEugene Syromyatnikov2021-10-122-17/+4
| | | | | | | | | | | | | | | | | | | | | | | | This feature, originally introduced by commit v4.23~52 "xlat.c: handle NULL xlat in lookup routines as incremental search", was poorly documented, was of limited use (the only use case was in print_array_ex, introduced in commit v4.23~91 "print_array: add support for printing array indices" (which means that between the two aforementioned commits printing xlats in indices was broken)), of limited value (it was actually useful only for sorted xlats, which are lg2(N) anyway, and even there an iteration from the saved cursor position is preferable for search continuation rather than bsearch), and ultimately was rendered non-operational by commit v5.3~105 "Add xlat description structure". * src/util.c (print_array_ex): Do not pass NULL as xlat in printxval_ex call. * src/xlat.c (xlookup): Remove x local static variable; remove static qualifier from idx and init it to 0; remove x, idx initialisation when xlat in non-NULL; remove xlat argument to x. (printxvals_ex): Remove the last local static variable and related logic. Reverts: v4.23~52 "xlat.c: handle NULL xlat in lookup routines as incremental search"

(SYS_FUNC(io_uring_register)) <case IORING_REGISTER_FILES2, case IORING_REGISTER_BUFFERS2>: Call print_io_uring_register_rsrc. (SYS_FUNC(io_uring_register)) <case IORING_REGISTER_FILES_UPDATE2, case IORING_REGISTER_BUFFERS_UPDATE>: Call print_io_uring_update_rsrc. * tests/io_uring_register.c (BIG_ADDR_MASK): New macro. (path_null, path_full): New constants, moved out of main. (print_rsrc_data, print_rsrc_tags): New functions. (main): Add checks for new decoders.

(SYS_FUNC(io_uring_register)) <case IORING_REGISTER_RESTRICTIONS>: New decoder, calls print_io_uring_restrictions. * src/xlat/uring_restriction_opcodes.in: New file. * src/xlat/uring_sqe_flags.in: Likewise. * tests/io_uring_register.c: Add checks for IORING_REGISTER_RESTRICTIONS. * NES: Mention this.
* src: use is_bigendianEugene Syromyatnikov2021-10-122-12/+3
| | | | | | | | * src/disable_ptrace_request.c (ARG_OFFSET): Remove. (main): Use is_bigendian-conditioned ternary operator instead of ARG_OFFSET. * src/sockaddr.c (btohs): Conditionalise return value on is_bigendian value.

* io_uring: explicitly list io_uring_register ops without argEugene Syromyatnikov2021-10-112-0/+9
| | | | | | | | | | * src/io_uring.c (SYS_FUNC(io_uring_register)): Add IORING_UNREGISTER_BUFFERS, IORING_UNREGISTER_FILES, IORING_UNREGISTER_EVENTFD, IORING_REGISTER_PERSONALITY, IORING_UNREGISTER_PERSONALITY, IORING_REGISTER_ENABLE_RINGS, and IORING_UNREGISTER_IOWQ_AFF to the opcode switch statement. * tests/io_uring_register.c: Add checks for IORING_REGISTER_ENABLE_RINGS and IORING_UNREGISTER_IOWQ_AFF.

| | | | | | * src/io_uring.c: Move "xlat/uring_enter_flags.h" and "xlat/uring_cqring_flags.h" forward to establish a lexicographical order of includes.
* defs: update print_array_ex doxygenEugene Syromyatnikov2021-10-111-13/+16
| | | | | | | | | | | | | | This change updates the description of index_xlat (as xlat is no longer a naked array, but rather a description structure), removes index_xlat_size description, and adds description for the return value semantics. Interestingly, the change that introduced index_xlat_size description (v5.3~15 "Add support for printing local arrays to print_array") was applied after the change that removed the argument (v5.3~105 "Add xlat description structure"). Complements: v5.3~15 "Add support for printing local arrays to print_array" * src/defs.h (print_array_ex): Update description.
* util: unify differently-sized variants of print_{,u,x}int_array_memberEugene Syromyatnikov2021-10-1135-169/+102

* bpf: fix bpf_prog_info.map_ids array printingEugene Syromyatnikov2021-10-113-87/+150
| | | | | | | | | | | | | | map_id_buf had an incorrect storage size (8 bytes instead of 4), which led to incorrect fetching of map_ids array elements, so only odd/even-indexed elements (on big/little-endian architectures, respectively) were printed. * src/bpf.c (print_bpf_prog_info): Change map_id_buf type from uint64_t to uint32_t. * tests/bpf-obj_get_info_by_fd.c: Create second bpf map, use it in the bpf program, and add additional checks regarding map_ids printing. * NEWS: Mention this. Fixes: v4.23~99 "bpf: decode bpf_attr.info field used by BPF_OBJ_GET_INFO_BY_FD command"
* Decode process_mrelease syscallEugene Syromyatnikov2021-10-118-0/+84
| | | | | | | | | | | | | | Introduced by Linux commits v5.14-159-g884a7e5964e0 and v5.14-160-gdce491039628. * src/linux/generic/syscallent-common.h ([BASE_NR + 448]): Add process_mrelease syscall entry. * src/mem.c (SYS_FUNC(process_mrelease)): New syscall decoder. * tests/.gitignore: Add process_mrelease and process_mrelease-y. * tests/gen_tests.in (process_mrelease, process_mrelease-y): New tests. * tests/process_mrelease.c: New file. * tests/process_mrelease-y.c: Likewise. * NEWS: Mention it.
* xlat: add MPOL_PREFERRED_MANY to mpol_modesEugene Syromyatnikov2021-10-114-11/+19

* bundled: update linux UAPI headers to v5.15-rc4Dmitry V. Levin2021-10-1015-12/+148
| | | | | | | | | | | | | | | | | | | | * bundled/linux/include/uapi/linux/btrfs.h: Update to headers_install'ed Linux kernel v5.15-rc4. * bundled/linux/include/uapi/linux/btrfs_tree.h: Likewise. * bundled/linux/include/uapi/linux/dm-ioctl.h: Likewise. * bundled/linux/include/uapi/linux/fs.h: Likewise. * bundled/linux/include/uapi/linux/if_bridge.h: Likewise. * bundled/linux/include/uapi/linux/if_link.h: Likewise. * bundled/linux/include/uapi/linux/in6.h: Likewise. * bundled/linux/include/uapi/linux/io_uring.h: Likewise. * bundled/linux/include/uapi/linux/mount.h: Likewise. * bundled/linux/include/uapi/linux/netfilter/nfnetlink_conntrack.h: Likewise. * bundled/linux/include/uapi/linux/pkt_sched.h: Likewise. * bundled/linux/include/uapi/linux/prctl.h: Likewise. * bundled/linux/include/uapi/linux/socket.h: Likewise. * bundled/linux/include/uapi/linux/v4l2-controls.h: Likewise. * bundled/linux/include/uapi/linux/version.h: Likewise.
* tests: use BE_LE macro in more placesEugene Syromyatnikov2021-10-095-64/+19
| | | | | | | | | | | It makes reading the code where only little pieces are switched on WORDS_BIGENDIAN a little bit easier. * tests/io_uring_register.c (BE_LE): Move it... * tests/tests.h (BE_LE): ...here. * tests/bpf.c (bpf_attr_check): Use BE_LE instead of #ifdef WORDS_BIGENDIAN. * tests/clone3.c: Likewise. * tests/nlattr_ifla_linkinfo.c: Likewise.
* tests/test_nlattr.h: helper macros for integer attr testingEugene Syromyatnikov2021-10-091-0/+49
| | | | | | | | | | It is one of the most common attribute type decoder flavours, so it should be as trivial to test as possible. * tests/test_nlattr.h (DEF_NLATTR_INTEGER_CHECK_, TEST_NLATTR_VAL): New macros. (check_u32_nlattr, check_x32_nlattr): New functions, defined using DEF_NLATTR_INTEGER_CHECK_.
* tests/test_nlattr.h: provide TEST_NLATTR_OBJECT_ and TEST_NLATTR_ARRAY_Eugene Syromyatnikov2021-10-091-7/+25
| | | | | | | | | | So they can be used along with custom nla_type string format. * tests/test_nlattr.h (TEST_NLATTR_OBJECT_): New macro, a wrapper for TEST_NLATTR_OBJECT_EX_. (TEST_NLATTR_ARRAY_): Rename from TEST_NLATTR_ARRAY, add nla_type_str_ argument. (TEST_NLATTR_ARRAY): New macro, a wrapper for TEST_NLATTR_ARRAY_.
* tests/tests.h: add struct strval16 typeEugene Syromyatnikov2021-10-091-0/+5
| | | | | | Analogous to strval32 and strval64. * tests/tests.h (struct strval16): New type.
* tests/test_nlattr: allow TEST_NLATTR_EX_ usage with various xlat verbosityEugene Syromyatnikov2021-10-091-2/+2
| | | | | | * tests/test_nlattr.h (TEST_NLATTR_EX_): Wrap MSG_DONTWAIT printing in XLAT_FMT/XLAT_ARG so it can be used with different xlat verbosity levels.
* rtnl_route: make encap type decoder globally availableEugene Syromyatnikov2021-10-092-6/+7
| | | | | | | | | And rename it to decode_nla_lwt_encap_type. * src/nlattr.h (DECL_NLA(lwt_encap_type)): New declaration. * src/rtnl_route.c (decode_rta_encap_type): Rename it to... (decode_nla_lwt_encap_type): ...this. (rtmsg_nla_decoders) <[RTA_ENCAP_TYPE]>: Use decode_nla_lwt_encap_type.
* nlattr: make xval/flag nlattr printing a bit more structuredEugene Syromyatnikov2021-10-092-12/+10
| | | | | | | | | | | | | | | Since the only usage for prefix/suffix was to enframe the xval/flag output in a function call syntax (that is inverse to process_fn), let's simply provide fn_str and print it using tprints_arg_begin and tprint_arg_end. * src/nlattr.h (decode_nla_xlat_opts): Remove prefix and suffix fields, add fn_str field. * src/nlattr.c (decode_nla_xval, decode_nla_flags): Output fn_str using tprints_arg_begin, call tprint_arg_end if fn_str is non-NULL. (decode_nla_ether_proto): Pass "htons" in fn_str field of the opts structure instead of "htons(" and ")" as prefix and suffix, respectively.
* ipc_msg: sign-extend msgtypEugene Syromyatnikov2021-10-091-1/+1
| | | | | | | | | | | Most of the architectures have indirect IPC calls for compat, but not ARM, and that unraveled a missing sign extension of the msgtyp argument before printing. * src/ipc_msg.c (tprint_msgrcv): Sign-extend msgtyp using truncate_klong_to_current_klongsize.
