Subject: [PATCH] util: update dumpstr
Use a buffer of a limited size, use proper type for dump amount, avoid
hard-coding of byte counts, calculate output buffer size more accurately
and minimise its rewriting, pad offset with zeros in accordance
with expected output amount.
* defs.h (dumpstr): Change the type of len argument from int to
kernel_ulong_t.
* macros.h (ROUNDUP_DIV): New macro.
(ROUNDUP): Rewrite using ROUNDUP_DIV.
* util.c (ILOG2_ITER_): New macro.
(ilog2_64, ilog2_32): New functions.
(ilog2_klong): New macro, wrapper around ilog2_32/ilog2_64, so (potentially
more expensive) ilog2_64 is not used for ilog2 calculation
of a kernel_ulong_t-typed variable on architectures with 32-bit kernel long.
(dumpstr): Update.

Subject: [PATCH 2/3] evdev: fix array size calculation in decode_bitset_
max_nr is in bits (as it is a number of flags), result is in bytes, and
the array allocation has to be in personality words.
There's still an open question, however, what to do on big-endian
architectures when a non-divisible-by-4 value is returned.
* evdev.c (decode_bitset_): Declare size_bits, initialise it and use it
later instead of size; round up size by personality's word boundary.

Subject: [PATCH 3/3] tests: test evdev bitset decoding more thoroughly
* tests/ioctl_evdev-success-v.test: Inject various values.
* tests/ioctl_evdev-success.test: Likewise.
* tests/ioctl_evdev-success.c (NUM_WORDS): New macro.
(struct evdev_check): Constify arg_ptr and print_arg args.
(invoke_test_syscall, test_evdev, print_input_absinfo, print_input_id,
print_mtslots): Add const qualifiers.
(print_getbit): Add const qualifiers, rewrite to expect trailing NULL
in the string array instead of leading string count.
(main): Set size for ev_more, ev_less, ev_zero arrays; replace leading
count element in ev_more_str, ev_less_str, ev_zero_str with trailing
NULL; replace ev_more_str and ev_less_str with ev_more_str_2/ev_less_str_2
and ev_more_str_3/ev_less_str_3 that differ by presence of flags that reside
beyond first two bytes; add static and const qualifiers where possible;
add key/key_sts_8/key_str_16 values; update a to provide either ev_more_str_2
or ev_more_str_3 and either key_str_8 or key_str_16 depending on inject_retval
value.

Subject: [PATCH] s390x: beautify sthyi data tail prints
The test already expects a ", " before the print of struct
padding. Let's add it to s390.c to make the output look a bit nicer and
fix test runs on z/VM that have padding at the end of the STHYI structs.
* s390.c (decode_ebcdic): Add missing comma.

Subject: [PATCH] unwind-libdw: fix initialization of libdwfl cache
This fixes stack trace printing for early syscalls that precede
the first syscall from memory mapping or execve families.
* unwind-libdw.c (tcb_init): Set struct ctx.last_proc_updating
to a value different from mapping_generation so that libdwfl cache
is properly initialized before the first use.
* NEWS: Mention this fix.
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1788636

Subject: [PATCH] tests: add strace-k-p test
Add a check of the stack unwinding for attached processes.
* tests/stack-fcall-attach.c: New file.
* tests/strace-k-p.expected: Likewise.
* tests/strace-k-p.test: New test.
* tests/Makefile.am (EXTRA_DIST): Add strace-k-p.expected and strace-k-p.test.
(STACKTRACE_TESTS): Add strace-k-p.test
(check_PROGRAMS): Add stack-fcall-attach.
(stack_fcall_attach_SOURCES): New variable.
* tests/stack-fcall.c: Include "tests.h" and <unistd.h>.
[!ATTACH_MODE] (ATTACH_MODE): Define to 0.
(main) [ATTACH_MODE]: Wait a bit.
* tests/strace-k.test: Add attach mode.
Complements: v5.4-18-g69b2c33 "unwind-libdw: fix initialization of libdwfl cache"
---
Backport changes:
* "SIGURG" line has been removed from tests/strace-k-p.expected, as it requires
v4.25~22 "Print stack traces on signals" and v4.25~21 "tests: check stack
unwinding for signals".
* "chdir" usage in tests/strace-k-p.expected has been replaced with "getpid",
as it is the syscall that was used in the stack-fcall.c at the time.
* Added the respective changes to tests/Makefile.in file.
* The changes to tests/stack-fcall-attach.c, tests/strace-k-p.expected,
tests/strace-k-p.test, tests/Makefile.am, tests/stack-fcall.c,
and tests/strace-k.test have been copied over to tests-m32 and tests-mx32
directories.

Subject: [PATCH] sockaddr: properly decode sockaddr_hci addresses without
hci_channel
Before Linux commit v2.6.38-rc1~476^2~14^2~3^2~43^2~9,
struct sockaddr_hci did not contain hci_channel field.
* configure.ac (AC_CHECK_HEADERS([bluetooth/bluetooth.h])): Add check
for struct sockaddr_hci.hci_channel.
* sockaddr.c (print_sockaddr_data_bt): Decode struct sockaddr_hci
without hci_channel field.
* tests/net-sockaddr.c (check_hci): Add check for struct sockaddr_hci
decoding without hci_channel field; guard hci_channel with #ifdef
HAVE_STRUCT_SOCKADDR_HCI_HCI_CHANNEL.
(check_raw): Remove "len++", as 4-byte AF_BLUETOOTH socket addresses are
interpreted as struct sockaddr_hci without hci_channel field.

Subject: [PATCH] bpf: add support for btf_* fields in BPF_MAP_CREATE
* bpf_attr.h (struct BPF_MAP_CREATE_struct): Add btf_fd,
btf_key_type_id, and btf_value_type_id fields.
* bpf.c (BEGIN_BPF_CMD_DECODER(BPF_MAP_CREATE)): Decode btf_fd,
btf_key_type_id, and btf_value_type_id fields introduced by Linux
commits v4.18-rc1~114^2~417^2~1^2~3 and v4.18-rc1~114^2~148^2~7^2~2.
* tests/bpf.c (BPF_MAP_CREATE_checks): Check it.
* tests/bpf-obj_get_info_by_fd.c (print_map_create): Update expected
output.

Subject: [PATCH] bpf: add support for *jited_ksyms and *jited_func_lens fields
in struct bpf_prog_info
* bpf_attr.h (struct bpf_prog_info_struct): Add nr_jited_ksyms,
nr_jited_func_lens, jited_ksyms, and jited_func_lens fields.
* bpf.c (struct obj_get_info_saved): Likewise.
(print_bpf_prog_info): Decode these fields introduced by Linux commits
v4.18-rc1~114^2~148^2~3^2~6 and v4.18-rc1~114^2~148^2~3^2~2.
* tests/bpf-obj_get_info_by_fd.c (main): Update expected output.

Subject: [PATCH] bpf: add support for new twelve fields in struct
bpf_prog_info
* bpf_attr.h (struct bpf_prog_info_struct): Add btf_id,
func_info_rec_size, func_info, nr_func_info, nr_line_info, line_info,
jited_line_info, nr_jited_line_info, line_info_rec_size,
jited_line_info_rec_size, nr_prog_tags, and prog_tags fields.
* bpf.c (struct obj_get_info_saved): Add func_info_rec_size,
nr_func_info, nr_line_info, jited_line_info, nr_jited_line_info,
line_info_rec_size, jited_line_info_rec_size, and nr_prog_tags fields.
(print_bpf_prog_info): Decode the twelve fields introduced by Linux
commits v5.0-rc1~129^2~209^2~16^2~8, v5.0-rc1~129^2~114^2~5^2~6,
v5.0-rc1~129^2~114^2^2~2, and v5.0-rc1~129^2~15^2~22.
* NEWS: Mention the latest bpf decoding enhancements.
* tests/bpf-obj_get_info_by_fd.c (main): Update expected output.

Unfortunately, strace 5.1 rebase didn't make it into RHEL 8.2.
As a result, ksystent tests now fails due to presence of new io_uring* syscalls.
Disable it for 8.2 in anticipation of a rebase in 8.3 timeframe.
