In cross builds, a target version of readelf has to be used
instead of a native one.
* configure.ac (AC_CHECK_TOOL): Add readelf.
* Makefile.am (READELF): New variable.
(mpers-m%.stamp): Pass it to $(srcdir)/mpers.sh.
* m4/mpers.m4 (st_MPERS): Pass READELF environment variable
to $srcdir/mpers_test.sh.
* mpers.sh (READELF): New variable.
Use it instead of readelf.
* maint/ioctls_sym.sh: Likewise.
* NEWS: Mention this fix.
Reported-by: Rolf Eike Beer <eb@emlix.com>
* tests/bpf.c (DEF_BPF_INIT_FIRST): New macro.
(init_BPF_MAP_CREATE_first, init_BPF_MAP_LOOKUP_ELEM_first,
init_BPF_PROG_LOAD_first, init_BPF_OBJ_PIN_first,
init_BPF_PROG_ATTACH_first, init_BPF_PROG_TEST_RUN_first,
init_BPF_PROG_GET_NEXT_ID_first, init_BPF_OBJ_GET_INFO_BY_FD_first):
Use it.
* configure.ac: Use AC_CHECK_MEMBERS instead of st_CHECK_UNION_BPF_ATTR
for union bpf_attr field checks as the former seems to be enough
for the case.
* m4/st_bpf.m4: Remove.
* configure.ac: Check for union bpf_attr.test.duration.
* bpf.c (decode_BPF_PROG_TEST_RUN): New function.
(SYS_FUNC(bpf)) <bpf_cmd_decoders>: Use it.
* NEWS: Mention this.
* tests/bpf.c: Include "print_fields.h".
Add macro guard for BPF_PROG_TEST_RUN decoder test.
[HAVE_UNION_BPF_ATTR_TEST_DURATION] (sample_BPF_PROG_TEST_RUN_attr):
New variable.
[HAVE_UNION_BPF_ATTR_TEST_DURATION] (init_BPF_PROG_TEST_RUN_first,
print_BPF_PROG_TEST_RUN_first, init_BPF_PROG_TEST_RUN_attr,
print_BPF_PROG_TEST_RUN_attr): New functions.
(main) [HAVE_UNION_BPF_ATTR_TEST_DURATION]: Use them.
Implement decoding of union bpf_attr.numa_node field for BPF_MAP_CREATE
command introduced by linux kernel commit v4.14-rc1~130^2~196^2~1.
* configure.ac: Check for numa_node member of union bpf_attr
instead of inner_map_fd.
(decode_BPF_MAP_CREATE): Add numa_node field to the structure, print it.
* NEWS: Mention this.
* tests/bpf.c: Update macro guards of BPF_MAP_CREATE decoder test.
(init_BPF_MAP_CREATE_first, print_BPF_MAP_CREATE_attr): Update expected
output.
(init_BPF_MAP_CREATE_attr): Initialize numa_node field, update offset.
The limit imposed by the kernel on the length of memfd_create first
argument is NAME_MAX - strlen("memfd:").
* memfd_create.c (SYS_FUNC(memfd_create)): Print the first argument
using printpathn.
* tests/memfd_create.c: Check it.
Since linux kernel provided a definition of MAP_TYPE in <asm/mman.h>
as long ago as in v2.4.0, it's safe to assume that MAP_TYPE is defined.
* mem.c (print_mmap_flags) [!MAP_TYPE]: Remove.
Although SHM_EXEC is available in <linux/shm.h> since kernel commit
v2.6.9-rc2~23^2~93^2~78, the glibc version of <sys/shm.h> did not
provide SHM_EXEC until commit glibc-2.10~238.
* xlat/shm_flags.in (SHM_EXEC): Add fallback definition.
* tests/shmxt.c (SHM_EXEC): Likewise.
These constants are universally available for quite a long time
and are used unconditionally in tests without any complaints.
* xlat/shmctl_flags.in: Remove fallback definitions.
NETLINK_LIST_MEMBERSHIPS, unlike all other SOL_NETLINK options, requests
not just a single integer but an array of integers. The kernel also
supports a zero optlen NETLINK_LIST_MEMBERSHIPS request.
* net.c (print_uint32): New function.
(print_getsockopt): Add ulen argument, rename len argument to rlen,
<SOL_NETLINK> Handle NETLINK_LIST_MEMBERSHIPS using print_array
and print_uint32.
(SYS_FUNC(getsockopt)): Pass ulen to print_getsockopt.
* tests/sockopt-sol_netlink.c (main): Check NETLINK_LIST_MEMBERSHIPS
decoding.
Tweak the parser to follow the kernel behaviour.
* net.c (print_getsockopt, print_setsockopt) <SOL_NETLINK>: Fetch and
print returned value as integer iff the length is >= sizeof(int),
otherwise print the address.
* NEWS: Mention this.
* xlat/socknetlinkoptions.in: New file.
* net.c: Include "xlat/socknetlinkoptions.h".
(print_sockopt_fd_level_name) <SOL_NETLINK>: Print name using
socknetlinkoptions.
* NEWS: Metnion this.
Analogous to the way it is done in xlat/gen.sh.
* maint/update_copyright_years.sh (MAX_JOBS): New variable, initialize
it to double the CPU count.
<while [ -n "${1:-}" ]; do case "$1" in>: Add -j option parsing.
(jobs, pids): New variables.
<git ls-files -- "$@" | grep -vFx "$IGNORED_FILES" | while read f; do>:
Execute process_file in background, count background jobs and wait
if there are too many.
Implement various features in order to make it suitable for the
generation of the CREDITS file:
- add an option for including contributor e-mail;
- add an option to read additional list of contributors from stdin;
- add shorthand for referring to the initial commit of the branch;
- document all of the above in a help message.
* maint/gen-contributors-list.sh (print_help): New function.
(script): Rename to SCRIPT.
(SCRIPT_NORM_EMAILS, MATCH_OUT, OUT_EMAILS, OUT_NO_EMAILS, read_stdin,
include_email): New variables.
Add parsing of options, rewrite input processing.
Unfortunately, he wasn't mentioned in the message of the commit
v4.19-68-g48cb633, so let's fix that omission.

This commit implements the following changes:
- increases the number of concurrent jobs to twice the CPU count;
- creates a circular buffer, so instead of running multiple jobs
at once, the generator tries to keep about the same number of jobs
being run concurrently;
- runs gen_git and gen_make concurrently in order to squeeze in
one more bit of concurrency.
With my deeply scientific measurements, this approach achieves
up to 15% speedup with dash and about 30-40% with bash as /bin/sh
on a 4-core machine.
* xlat/gen.sh (main): Declare pids local variable, append pid of every
run job to it; increase the limit of jobs to ncpus * 2; when the limit
is reached, wait for the first pid in pids instead of resetting jobs
to zero and waiting for all the run jobs; put gen_git and gen_make
into background.
