GNU LESSER GENERAL PUBLIC LICENSE
Version 2.1, February 1999
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies of this
license document, but changing it is not allowed.
[This is the first released version of the Lesser GPL. It also counts
as the successor of the GNU Library Public License, version 2, hence
the version number 2.1.]
Preamble
The licenses for most software are designed to take away your freedom
to share and change it. By contrast, the GNU General Public Licenses are
intended to guarantee your freedom to share and change free software--to
make sure the software is free for all its users.
This license, the Lesser General Public License, applies to some specially
designated software packages--typically libraries--of the Free Software
Foundation and other authors who decide to use it. You can use it too,
but we suggest you first think carefully about whether this license or
the ordinary General Public License is the better strategy to use in
any particular case, based on the explanations below.
When we speak of free software, we are referring to freedom of use,
not price. Our General Public Licenses are designed to make sure that
you have the freedom to distribute copies of free software (and charge
for this service if you wish); that you receive source code or can get it
if you want it; that you can change the software and use pieces of it in
new free programs; and that you are informed that you can do these things.
To protect your rights, we need to make restrictions that forbid
distributors to deny you these rights or to ask you to surrender these
rights. These restrictions translate to certain responsibilities for
you if you distribute copies of the library or if you modify it.
For example, if you distribute copies of the library, whether gratis
or for a fee, you must give the recipients all the rights that we gave
you. You must make sure that they, too, receive or can get the source
code. If you link other code with the library, you must provide complete
object files to the recipients, so that they can relink them with the
library after making changes to the library and recompiling it. And you
must show them these terms so they know their rights.
We protect your rights with a two-step method: (1) we copyright the
library, and (2) we offer you this license, which gives you legal
permission to copy, distribute and/or modify the library.
To protect each distributor, we want to make it very clear that there
is no warranty for the free library. Also, if the library is modified
by someone else and passed on, the recipients should know that what they
have is not the original version, so that the original author's reputation
will not be affected by problems that might be introduced by others.
Finally, software patents pose a constant threat to the existence of
any free program. We wish to make sure that a company cannot effectively
restrict the users of a free program by obtaining a restrictive license
from a patent holder. Therefore, we insist that any patent license
obtained for a version of the library must be consistent with the full
freedom of use specified in this license.
Most GNU software, including some libraries, is covered by the ordinary
GNU General Public License. This license, the GNU Lesser General
Public License, applies to certain designated libraries, and is quite
different from the ordinary General Public License. We use this license
for certain libraries in order to permit linking those libraries into
non-free programs.
When a program is linked with a library, whether statically or using a
shared library, the combination of the two is legally speaking a combined
work, a derivative of the original library. The ordinary General Public
License therefore permits such linking only if the entire combination
fits its criteria of freedom. The Lesser General Public License permits
more lax criteria for linking other code with the library.
We call this license the "Lesser" General Public License because it
does Less to protect the user's freedom than the ordinary General
Public License. It also provides other free software developers Less
of an advantage over competing non-free programs. These disadvantages
are the reason we use the ordinary General Public License for many
libraries. However, the Lesser license provides advantages in certain
special circumstances.
For example, on rare occasions, there may be a special need to encourage
the widest possible use of a certain library, so that it becomes a
de-facto standard. To achieve this, non-free programs must be allowed
to use the library. A more frequent case is that a free library does
the same job as widely used non-free libraries. In this case, there
is little to gain by limiting the free library to free software only,
so we use the Lesser General Public License.
In other cases, permission to use a particular library in non-free
programs enables a greater number of people to use a large body of free
software. For example, permission to use the GNU C Library in non-free
programs enables many more people to use the whole GNU operating system,
as well as its variant, the GNU/Linux operating system.
Although the Lesser General Public License is Less protective of the
users' freedom, it does ensure that the user of a program that is linked
with the Library has the freedom and the wherewithal to run that program
using a modified version of the Library.
The precise terms and conditions for copying, distribution and
modification follow. Pay close attention to the difference between a
"work based on the library" and a "work that uses the library". The
former contains code derived from the library, whereas the latter must
be combined with the library in order to run.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library or other
program which contains a notice placed by the copyright holder or
other authorized party saying it may be distributed under the terms of
this Lesser General Public License (also called "this License"). Each
licensee is addressed as "you".
A "library" means a collection of software functions and/or data
prepared so as to be conveniently linked with application programs
(which use some of those functions and data) to form executables.
The "Library", below, refers to any such software library or work
which has been distributed under these terms. A "work based on
the Library" means either the Library or any derivative work under
copyright law: that is to say, a work containing the Library or a
portion of it, either verbatim or with modifications and/or translated
straightforwardly into another language. (Hereinafter, translation
is included without limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for
making modifications to it. For a library, complete source code
means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the library.
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of running
a program using the Library is not restricted, and output from such
a program is covered only if its contents constitute a work based
on the Library (independent of the use of the Library in a tool for
writing it). Whether that is true depends on what the Library does
and what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's
complete source code as you receive it, in any medium, provided
that you conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep intact
all the notices that refer to this License and to the absence of any
warranty; and distribute a copy of this License along with the Library.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Library or any portion of
it, thus forming a work based on the Library, and copy and distribute
such modifications or work under the terms of Section 1 above,
provided that you also meet all of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices
stating that you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no charge
to all third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a
table of data to be supplied by an application program that uses
the facility, other than as an argument passed when the facility
is invoked, then you must make a good faith effort to ensure that,
in the event an application does not supply such function or table,
the facility still operates, and performs whatever part of its
purpose remains meaningful.
(For example, a function in a library to compute square roots
has a purpose that is entirely well-defined independent of
the application. Therefore, Subsection 2d requires that any
application-supplied function or table used by this function must
be optional: if the application does not supply it, the square root
function must still compute square roots.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Library,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work
based on the Library, the distribution of the whole must be on the
terms of this License, whose permissions for other licensees extend
to the entire whole, and thus to each and every part regardless of
who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is
to exercise the right to control the distribution of derivative or
collective works based on the Library.
In addition, mere aggregation of another work not based on the Library
with the Library (or with a work based on the Library) on a volume
of a storage or distribution medium does not bring the other work
under the scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library. To
do this, you must alter all the notices that refer to this License,
so that they refer to the ordinary GNU General Public License,
version 2, instead of to this License. (If a newer version than
version 2 of the ordinary GNU General Public License has appeared,
then you can specify that version instead if you wish.) Do not make
any other change in these notices.
Once this change is made in a given copy, it is irreversible for
that copy, so the ordinary GNU General Public License applies to all
subsequent copies and derivative works made from that copy.
This option is useful when you wish to copy part of the code of the
Library into a program that is not a library.
4. You may copy and distribute the Library (or a portion or derivative
of it, under Section 2) in object code or executable form under the
terms of Sections 1 and 2 above provided that you accompany it with
the complete corresponding machine-readable source code, which must
be distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange.
If distribution of object code is made by offering access to copy from
a designated place, then offering equivalent access to copy the source
code from the same place satisfies the requirement to distribute the
source code, even though third parties are not compelled to copy the
source along with the object code.
5. A program that contains no derivative of any portion of the Library,
but is designed to work with the Library by being compiled or linked
with it, is called a "work that uses the Library". Such a work, in
isolation, is not a derivative work of the Library, and therefore
falls outside the scope of this License.
However, linking a "work that uses the Library" with the Library
creates an executable that is a derivative of the Library (because it
contains portions of the Library), rather than a "work that uses the
library". The executable is therefore covered by this License. Section
6 states terms for distribution of such executables.
When a "work that uses the Library" uses material from a header
file that is part of the Library, the object code for the work may
be a derivative work of the Library even though the source code is
not. Whether this is true is especially significant if the work can
be linked without the Library, or if the work is itself a library. The
threshold for this to be true is not precisely defined by law.
If such an object file uses only numerical parameters, data structure
layouts and accessors, and small macros and small inline functions
(ten lines or less in length), then the use of the object file
is unrestricted, regardless of whether it is legally a derivative
work. (Executables containing this object code plus portions of the
Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may
distribute the object code for the work under the terms of Section
6. Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.
6. As an exception to the Sections above, you may also combine or link
a "work that uses the Library" with the Library to produce a work
containing portions of the Library, and distribute that work under
terms of your choice, provided that the terms permit modification
of the work for the customer's own use and reverse engineering for
debugging such modifications.
You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered
by this License. You must supply a copy of this License. If the work
during execution displays copyright notices, you must include the
copyright notice for the Library among them, as well as a reference
directing the user to the copy of this License. Also, you must do
one of these things:
a) Accompany the work with the complete corresponding
machine-readable source code for the Library including whatever
changes were used in the work (which must be distributed under
Sections 1 and 2 above); and, if the work is an executable linked
with the Library, with the complete machine-readable "work that
uses the Library", as object code and/or source code, so that the
user can modify the Library and then relink to produce a modified
executable containing the modified Library. (It is understood
that the user who changes the contents of definitions files in the
Library will not necessarily be able to recompile the application
to use the modified definitions.)
b) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (1) uses at run time a
copy of the library already present on the user's computer system,
rather than copying library functions into the executable, and
(2) will operate properly with a modified version of the library,
if the user installs one, as long as the modified version is
interface-compatible with the version that the work was made with.
c) Accompany the work with a written offer, valid for at least three
years, to give the same user the materials specified in Subsection
6a, above, for a charge no more than the cost of performing this
distribution.
d) If distribution of the work is made by offering access to copy
from a designated place, offer equivalent access to copy the above
specified materials from the same place.
e) Verify that the user has already received a copy of these
materials or that you have already sent this user a copy.
For an executable, the required form of the "work that uses the
Library" must include any data and utility programs needed for
reproducing the executable from it. However, as a special exception,
the materials to be distributed need not include anything that is
normally distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on
which the executable runs, unless that component itself accompanies
the executable.
It may happen that this requirement contradicts the license
restrictions of other proprietary libraries that do not normally
accompany the operating system. Such a contradiction means you
cannot use both them and the Library together in an executable that
you distribute.
7. You may place library facilities that are a work based on the
Library side-by-side in a single library together with other library
facilities not covered by this License, and distribute such a combined
library, provided that the separate distribution of the work based on
the Library and of the other library facilities is otherwise permitted,
and provided that you do these two things:
a) Accompany the combined library with a copy of the same work based
on the Library, uncombined with any other library facilities. This
must be distributed under the terms of the Sections above.
b) Give prominent notice with the combined library of the fact
that part of it is a work based on the Library, and explaining
where to find the accompanying uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute the
Library except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense, link with, or distribute the
Library is void, and will automatically terminate your rights under
this License. However, parties who have received copies, or rights,
from you under this License will not have their licenses terminated
so long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify
or distribute the Library or its derivative works. These actions
are prohibited by law if you do not accept this License. Therefore,
by modifying or distributing the Library (or any work based on the
Library), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Library or works based on it.
10. Each time you redistribute the Library (or any work based on
the Library), the recipient automatically receives a license from
the original licensor to copy, distribute, link with or modify the
Library subject to these terms and conditions. You may not impose
any further restrictions on the recipients' exercise of the rights
granted herein. You are not responsible for enforcing compliance by
third parties with this License.
11. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement
or otherwise) that contradict the conditions of this License, they
do not excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence
you may not distribute the Library at all. For example, if a patent
license would not permit royalty-free redistribution of the Library
by all those who receive copies directly or indirectly through you,
then the only way you could satisfy both it and this License would
be to refrain entirely from distribution of the Library.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended
to apply, and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of
any such claims; this section has the sole purpose of protecting
the integrity of the free software distribution system which
is implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed
to be a consequence of the rest of this License.
12. If the distribution and/or use of the Library is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Library under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
13. The Free Software Foundation may publish revised and/or new
versions of the Lesser General Public License from time to time. Such
new versions will be similar in spirit to the present version, but
may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Library
specifies a version number of this License which applies to it and
"any later version", you have the option of following the terms and
conditions either of that version or of any later version published
by the Free Software Foundation. If the Library does not specify a
license version number, you may choose any version ever published by
the Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free
programs whose distribution conditions are incompatible with these,
write to the author to ask for permission. For software which is
copyrighted by the Free Software Foundation, write to the Free Software
Foundation; we sometimes make exceptions for this. Our decision will
be guided by the two goals of preserving the free status of all
derivatives of our free software and of promoting the sharing and
reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE
LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS
AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF
ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO
IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY
MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE
TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE
THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR
A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN
IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES. END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest
possible use to the public, we recommend making it free software that
everyone can redistribute and change. You can do so by permitting
redistribution under these terms (or, alternatively, under the terms of
the ordinary General Public License).
To apply these terms, attach the following notices to the library. It is
safest to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.
<one line to give the library's name and an idea of what it does.>
Copyright (C) <year> <name of author>
This library is free software; you can redistribute it and/or modify it
under the terms of the GNU Lesser General Public License as published
by the Free Software Foundation; either version 2.1 of the License, or
(at your option) any later version.
This library is distributed in the hope that it will be useful, but
WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY
or FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public
License for more details.
You should have received a copy of the GNU Lesser General Public License
along with this library; if not, write to the Free Software Foundation,
Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Also add information on how to contact you by electronic and paper mail.
You should also get your employer (if you work as a programmer) or
your school, if any, to sign a "copyright disclaimer" for the library,
if necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in
the library `Frob' (a library for tweaking knobs) written

===============================================
* Changes in behaviour
* On x32 personality, 64-bit syscalls (such as readv) are now shown with "#64"
suffix instead of "64:" prefix. Unlike the old names, these new names
can be used in syscall qualification expressions.
* Changed error number output format: error numbers are consistently

regardless of -e raw qualification settings. One can specify
-X raw for displaying raw error numbers unconditionally.

Debian bug #692915).
* Added support for personality designation ("64", "32", or "x32") to syscall
qualifications in -e trace expressions.
* Implemented injection of syscalls with no side effects as an alternative
to injection of an invalid syscall (-e inject=SET:syscall= expression).

ioctl commands.
* Enhanced decoding of AF_BLUETOOTH socket addresses.
* Implemented decoding of io_pgetevent syscall.
* Wired up rseq syscall.
* Updated lists of ADJ_*, BPF_*, BPF_F_*, BPF_PROG_TYPE_*, ETH_P_*, FPE_*,
IFF_*, IPPROTO_*, MAP_*, MS_*, MSG_*, NETLINK_*, PACKET_*, PROT_*, SCTP_*,
SECCOMP_FILTER_FLAG_*, SEGV_*, SEM_*, SHM_*, SW_*, V4L2_CID_*,

Noteworthy changes in release 4.22 (2018-04-05)
===============================================
* Changes in infrastructure
* The mailing list was moved to strace-devel@lists.strace.io.
* SourceForge git repository
(https://sourceforge.net/p/strace/code/ci/master/tree/) is no longer
maintained. Please use GitLab (https://gitlab.com/strace/strace/)
or GitHub (https://github.com/strace/strace/) repository instead.
* Changes in behaviour
* When printing string data, '8' and '9' following an octal escape sequence
no longer lead to unabbreviated octal escape sequence output, as they used
to do.
* Angle brackets are now printed as octal number escape sequences
in the output of paths associated with file descriptors.
* Data dump for write syscalls (-e write) is performed regardless
of successfulness of these syscall (addresses Debian bug #436284).
* -r and -t options are now affect output independently. Previously,
-r option led to ignoring of the -t option (addresses Debian bug #466195).
* Improvements
* Implemented delay injection (-e inject=SET:delay_enter= and
-e inject=SET:delay_exit= options).
* Added -A option for opening output files in append mode
(addresses Debian bug #528488).
* IPv6 addresses shown in socket information in -yy mode are now printed
in brackets.
* Enhanced decoding of bpf, prctl and ptrace syscalls.
* Enhanced decoding of BTRFS_IOC_INO_PATHS, BTRFS_IOC_LOGICAL_INO, and PTP_*
ioctl commands.

in v4l2 structures.
* Enhanced decoding of kern_features syscall.
* Enhanced NETLINK_NETFILTER netlink protocol decoder.
* Optimized handling of large number of tracees.
* Improved wall clock time measurement in syscall count statistics
(-c -w option).
* Extended the range of allowed values in -e inject=...:retval= expression.
* Added i18n support.
* Updated lists of ioctl commands from Linux 4.16.
* Enhanced manual page.
* Bug fixes
* Fixed build on m68k.
* Fixed v4l2 pixelformat decoding on big-endian architectures.
* Fixed -O option.
Noteworthy changes in release 4.21 (2018-02-13)
===============================================
* Changes in behaviour
* Warning is now issued when -F option is used.
* Warning is now issued when a tracee with unsupported personality
is attached.
* Unknown syscall numbers are now printed in hexadecimal form.
* Improvements
* Implemented decoding of netlink descriptor attributes as file descriptors.
* Implemented decoding of hugetlb page size selection flags.
* Implemented decoding of BPF_PROG_TEST_RUN, BPF_PROG_GET_NEXT_ID,
BPF_MAP_GET_NEXT_ID, BPF_PROG_GET_FD_BY_ID, BPF_MAP_GET_FD_BY_ID,
and BPF_OBJ_GET_INFO_BY_FD commands of bpf syscall.
* Enhanced decoding of get_thread_area, memfd_create, modify_ldt,
perf_event_open, reboot, s390_guarded_storage, s390_pcio_mmio_read,
s390_pci_mmio_write, s390_runtime_instr, s390_sthyi, set_thread_area,
and shmget syscalls.
* Implemented decoding of KVM_* and DM_LIST_DEVICES ioctl commands.
* Implemented decoding of riscv_flush_icache syscall.
* Enhanced decoding of getsockopt and setsockopt syscalls for SOL_NETLINK
level.
* Enhanced decoding of BPF_MAP_CREATE command of bpf syscall.
* Print values returned by mq_open syscall and first arguments
of mq_getsetattr, mq_notify, mq_timedreceive, and mq_timedsend syscalls
as file descriptors.
* Added decoding of get_tls syscall on arm.
* Added -e trace=%pure option for tracing system calls with no arguments that
never fail.
* Updated lists of IPV6_*, MAP_*, MEMBARRIER_CMD_*, MSG_*, NT_*, PKEY_*,
SHM_*, and TCP_* constants.
* Added manual page for the strace-log-merge command.
* Updated lists of ioctl commands from Linux 4.15.
* Implemented biarch support for s390x.
* Implemented an optional support for symbol demangling in strace -k output
(activated by --with-libiberty configure option).
* Information about availability of demangling and reliable personality
decoding (on architectures with multiple personalities) is now available
in strace -V output.
* Added decoding of pkey_alloc, pkey_free, and pkey_mprotect syscalls on
powerpc and powerpc64.
* Enhanced manual page.
* Bug fixes
* Fixed multi-personality support in cross builds.
* Added mq_getsetattr, mq_notify, mq_open, mq_timedreceive, and mq_timedsend
syscalls to %desc tracing set.
* Fixed path tracing support for mmap syscalls with indirect arguments and
for old select syscall.
* Fixed decoding of arm-specific (__ARM_NR_*) syscalls.
* Fixed open mode flags decoding.
* Fixed corner cases in handling of strace -ff -ttt logs by strace-log-merge.
* Error counts that exceed one billion are now printed correctly in call
summary output.
* Fixed call summary header for x32 personality.
* Changes of tracee personalities are reported more reliably.
* Fixed the case when strace attaches to a tracee being inside exec and its
first syscall stop is syscall-exit-stop instead of syscall-enter-stop,
which messed up all the syscall state tracking.
* Fixed printing of higher 32 bits of the return value for x32 personality.
* Portability
* A C compiler that supports "for" loop initial declarations is now required.
* Inability to configure multiple personality support on architectures where
multiple personalities are supported leads to configuration failure during
build now. Use --enable-mpers=check to revert to the old behaviour.
* Build-time requirement for the mpers support has been lowered from gawk 4
to gawk 3.
* Removed incomplete and non-functional support for the CRIS architecture.
* Removed incomplete and unused support for IA-32 mode on the IA-64
architecture.

github/gitlab autogenerated archives are not supported
======================================================
This information applies to bundles automatically generated
by github and gitlab.
strace's program version is maintained using git-version-gen script, therefore,
building strace depends on "git describe" (a full git clone is needed for this)
or, alternatively, a .tarball-version file. Neither github nor gitlab can
provide the latter, they also do not allow to inject a .tarball-version file
during export archiving.

=======================
Each commit log should always start with a one-line summary, the second
line should be blank, and the remaining lines are usually ChangeLog-style
entries for all affected files, except the leading TABs which should
be omitted.
Changes must not introduce whitespace errors in git sense (trailing
whitespace, spaces before tabs, spaces for indentation, blank lines
at the end of file), this can be checked with the following command:
git -c core.whitespace=space-before-tab,trailing-space diff-index \
--check 4b825dc642cb6eb9a060e54bf8d69288fbee4904
It is also preferred (but not required) that commit patches pass
scripts/checkpatch.pl script from the Linux kernel[1], as currently established
coding style quite closely resembles the one used in Linux kernel[2], with some
exceptions.

0. BUILD REQUIREMENTS
- Sane POSIX shell.
- gcc-like compiler that supports C99 and some GNU extensions (namely, empty
structures, empty definitions, zero length arrays, ranged designated
initialisers).
- libc. GNU libc and musl are supported.
- Linux UAPI headers.
- GNU Make.
- GNU coreutils.
- For running test suite: gawk, grep, sed, runtime environment for all
personalities.
- Requirements for optional features are documented in their description.
1. CONFIGURATION AND OPTIONAL FEATURES
Configuration is done using GNU Autoconf-generated configure script.
Please refer to the README-configure file for generic information regarding
configure usage.
In addition to standard configure options, strace's configure file provides
the following options:
1.1. Additional build and testing hardening
--enable-gcc-Werror turn on gcc's -Werror option
--enable-code-coverage Whether to enable code coverage support
--with-gcov=GCOV use given GCOV for coverage (GCOV=gcov).
--enable-valgrind Whether to enable Valgrind on the unit tests
--disable-valgrind-memcheck
Whether to skip memcheck during the Valgrind tests
--disable-valgrind-helgrind
Whether to skip helgrind during the Valgrind tests
--disable-valgrind-drd Whether to skip drd during the Valgrind tests
--enable-valgrind-sgcheck
Whether to use sgcheck during the Valgrind tests
1.2. Optional features
1.2.1. Multiple personalities support
--enable-mpers=yes|no|check|m32|mx32
whether to enable multiple personalities support
required for proper decoding of structures used by
tracees with personalities that differ from the
personality of strace, default is yes.
Personality is a way system call is performed (in terms of ABI). For example,
Linux kernel on multiple 64-bit architectures that evolve from their 32-bit
counterparts have support for running 32-bit binaries with 32-bit system call
ABI, and that system call ABI constitutes a separate personality in strace's
terms. Another example is 32-on-64 bit ABI; while exploiting the same way for
performing system calls as native 64-bit system calls, this ABI has different
type sizes and, as a result, also constitutes a separate personality; the only
such ABI that is currently supported by strace is x32 on x86_64. This is
important as different ABIs use different alignments and type sizes, as a
result, fields in structures in unions have different offsets on different
ABIs. In order to be able to correctly parse all the structures used in various
system calls and ioctl commands, strace compiles these structure definitions
for these different ABI and then parses DWARF of these compiled definitions in
order to generate proper structure definitions that compiled with decoder code.
Taking the aforementioned into account, there are the following requirements:
- gawk (at least version 3)
- Ability to compile for m32 personality (on architectures where it is supported)
- On x86_64, x32, powerpc64, sparc64, riscv64, tile64: gcc -m32
- s390x: gcc -m31
- AArch64: a separate compiler for armv7 EABI
- See information about configuration in "1.3.2. AArch64: AArch32 support"
- Ability to compile for mx32 personality (on architectures where it is supported)
- On x86_64: gcc -mx32
- For tests: runtime support (linker, libc, and loader)
1.2.2. Stack unwinding (-k option)
--with-libunwind use libunwind to implement stack tracing support
--with-libiberty use libiberty to demangle symbols in stack trace
1.3. Architecture-specific features
1.3.1. ARMv7: OABI support
--enable-arm-oabi enable OABI support on ARM EABI
1.3.2. AArch64: AArch32 support
CC_FOR_M32
CPP_FOR_M32
CFLAGS_FOR_M32
CPPFLAGS_FOR_M32
1.4. Miscellanea
1.4.1. Static build configuration
For static linking, provide LDFLAGS='-static -pthread'.
1.4.2. Cross-compilation configuration
2. BUILDING
make
make V=1
3. TESTING
make check
TESTS='list of tests'
VALGRIND_FLAGS
TIMEOUT_DURATION
BTRFS_MOUNTPOINT
4. ADDITIONAL TARGETS
make code-coverage-capture
make code-coverage-capture CODE_COVERAGE_BRANCH_COVERAGE=
5. INSTALLATION
make install
6. PACKAGING
6.1. Distribution tarball
./make-dist
Requires git
6.2. dpkg package
6.3. RPM package

This is strace - a diagnostic, debugging and instructional userspace utility
with a traditional command-line interface for Linux. It is used to monitor
and tamper with interactions between processes and the Linux kernel, which
include system calls, signal deliveries, and changes of process state.
The operation of strace is made possible by the kernel feature known as ptrace.
strace is released under the terms of the GNU Lesser General Public License
version 2.1 or later; see the file COPYING for details.
strace test suite is released under the terms of the GNU General Public License
version 2 or later; see the file tests/COPYING for details.
See the file CREDITS for a list of authors and other contributors.
See the file INSTALL for compilation and installation instructions.
See the file NEWS for information on what has changed in recent versions.
See the file README-hacking for information related to strace development.
The project's homepage is at
https://strace.io
The GIT repository of strace is available at
https://github.com/strace/strace/ and https://gitlab.com/strace/strace/
strace has a mailing list:
strace-devel@lists.strace.io
Everyone is welcome to post bug reports, feature requests, comments
and patches to the list. The mailing list archives are available at
https://lists.strace.io/pipermail/strace-devel/
System requirements:
* Linux kernel >= 2.6.18 is recommended. Older versions might still work
but they haven't been thoroughly tested with this release.
* Linux kernel >= 2.5.46 is required.
Older versions without a decent PTRACE_SETOPTIONS support will not work.
* On mips, Linux kernel >= 2.6.15 is required.
Older versions without a decent PTRACE_GETREGS support will not work.
* On s390 and s390x, Linux kernel >= 2.6.27 is required.
Older versions without a decent PTRACE_GETREGSET support will not work.
