+
+According to drivers/input/evdev.c:bits_to_user(),
+the Linux kernel returns the number of bytes, not bits.
+
+* evdev.c (decode_bitset_): Treat syscall return value as the number
+of bytes.
+
+Co-Authored-by: Dmitry V. Levin <ldv@altlinux.org>

+Subject: [PATCH 02/27] evdev: fix decoding of EVIOCGBIT(0, ...)
+
+There is a comment in drivers/input/evdev.c which says:
+/* EV_SYN==0 is EV_CNT, _not_ SYN_CNT, see EVIOCGBIT */
+
+That is, EVIOCGBIT(0, ...) should return a bit mask with supported
+event types instead of SYN_* event codes.
+
+* defs.h (evdev_ev): New prototype.
+* evdev.c: Include "xlat/evdev_ev.h" and remove "xlat/evdev_sync.h".
+(bit_ioctl) <case EV_SYN>: Replace EV_SYN with 0, use evdev_ev
+with XT_SORTED in decode_bitset invocation instead.
+* ioctl.c: Do not include "xlat/evdev_ev.h".
+(evdev_decode_number): Print nr == 0x20 as "0" instead of "EV_SYN".
+* tests/ioctl_evdev.c (main): Use 0 instead of EV_SYN in EVIOCGBIT
+output.
+* xlat/evdev_sync.in: Remove.
+
+Additional changes:
+ xlat/evdev_ev.h (auto-generated from xlat/evdev_ev.in)
+
+Co-Authored-by: Dmitry V. Levin <ldv@altlinux.org>

+Subject: [PATCH 04/27] strace.c: introduce struct tcb_wait_data
+
+Introduce a new structure to pass information between next_event(),
+restart_delayed_tcb(), and dispatch_event().
+
+This is going to be used by a subsequent change of next_event().
+
+* strace.c (struct tcb_wait_data): New type.
+(next_event): Remove parameters, return a pointer
+to const struct tcb_wait_data. Return NULL instead of TE_BREAK.
+(dispatch_event): Replace all parameters with a pointer
+to const struct tcb_wait_data, obtain the trace event, siginfo,
+and status from its fields.
+(restart_delayed_tcb): Add local struct tcb_wait_data variable
+with te field set to TE_RESTART, pass it to dispatch_event().
+(main): Remove status and si variables, update next_event()
+and dispatch_event() invocations.

++GNU GENERAL PUBLIC LICENSE
++
++Version 2, June 1991
++
++Copyright (C) 1989, 1991 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.
++
++Preamble
++
++The licenses for most software are designed to take away your freedom
++to share and change it. By contrast, the GNU General Public License is
++intended to guarantee your freedom to share and change free software--to
++make sure the software is free for all its users. This General Public
++License applies to most of the Free Software Foundation's software and
++to any other program whose authors commit to using it. (Some other Free
++Software Foundation software is covered by the GNU Lesser General Public
++License instead.) You can apply it to your programs, too.
++
++When we speak of free software, we are referring to freedom, 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 or use pieces of it in
++new free programs; and that you know you can do these things.
++
++To protect your rights, we need to make restrictions that forbid anyone
++to deny you these rights or to ask you to surrender the rights. These
++restrictions translate to certain responsibilities for you if you
++distribute copies of the software, or if you modify it.
++
++For example, if you distribute copies of such a program, whether gratis or
++for a fee, you must give the recipients all the rights that you have. You
++must make sure that they, too, receive or can get the source code. And
++you must show them these terms so they know their rights.
++
++We protect your rights with two steps: (1) copyright the software, and
++(2) offer you this license which gives you legal permission to copy,
++distribute and/or modify the software.
++
++Also, for each author's protection and ours, we want to make certain
++that everyone understands that there is no warranty for this free
++software. If the software is modified by someone else and passed on,
++we want its recipients to know that what they have is not the original,
++so that any problems introduced by others will not reflect on the original
++authors' reputations.
++
++Finally, any free program is threatened constantly by software
++patents. We wish to avoid the danger that redistributors of a free
++program will individually obtain patent licenses, in effect making the
++program proprietary. To prevent this, we have made it clear that any
++patent must be licensed for everyone's free use or not licensed at all.
++
++The precise terms and conditions for copying, distribution and
++modification follow.
++
++TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
++
++ 0. This License applies to any program or other work which contains
++ a notice placed by the copyright holder saying it may be distributed
++ under the terms of this General Public License. The "Program", below,
++ refers to any such program or work, and a "work based on the Program"
++ means either the Program or any derivative work under copyright law:
++ that is to say, a work containing the Program or a portion of it,
++ either verbatim or with modifications and/or translated into another
++ language. (Hereinafter, translation is included without limitation
++ in the term "modification".) Each licensee is addressed as "you".
++
++ Activities other than copying, distribution and modification are not
++ covered by this License; they are outside its scope. The act of running
++ the Program is not restricted, and the output from the Program is
++ covered only if its contents constitute a work based on the Program
++ (independent of having been made by running the Program). Whether
++ that is true depends on what the Program does.
++
++ 1. You may copy and distribute verbatim copies of the Program's 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 give any
++ other recipients of the Program a copy of this License along with
++ the Program.
++
++ 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 Program or any portion of
++ it, thus forming a work based on the Program, 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) You must cause the modified files to carry prominent notices
++ stating that you changed the files and the date of any change.
++
++ b) You must cause any work that you distribute or publish, that
++ in whole or in part contains or is derived from the Program or
++ any part thereof, to be licensed as a whole at no charge to all
++ third parties under the terms of this License.
++
++ c) If the modified program normally reads commands interactively
++ when run, you must cause it, when started running for such
++ interactive use in the most ordinary way, to print or display
++ an announcement including an appropriate copyright notice and
++ a notice that there is no warranty (or else, saying that you
++ provide a warranty) and that users may redistribute the program
++ under these conditions, and telling the user how to view a copy
++ of this License. (Exception: if the Program itself is interactive
++ but does not normally print such an announcement, your work based
++ on the Program is not required to print an announcement.)
++
++ These requirements apply to the modified work as a whole. If
++ identifiable sections of that work are not derived from the Program,
++ 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 Program, 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 Program.
++
++ In addition, mere aggregation of another work not based on the Program
++ with the Program (or with a work based on the Program) on a volume
++ of a storage or distribution medium does not bring the other work
++ under the scope of this License.
++
++ 3. You may copy and distribute the Program (or a work based on it,
++ under Section 2) in object code or executable form under the terms of
++ Sections 1 and 2 above provided that you also do one of the following:
++
++ a) 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;
++ or,
++
++ b) Accompany it with a written offer, valid for at least three
++ years, to give any third party, for a charge no more than your
++ cost of physically performing source distribution, a complete
++ machine-readable copy of the corresponding source code, to be
++ distributed under the terms of Sections 1 and 2 above on a medium
++ customarily used for software interchange; or,
++
++ c) Accompany it with the information you received as to the offer to
++ distribute corresponding source code. (This alternative is allowed
++ only for noncommercial distribution and only if you received the
++ program in object code or executable form with such an offer,
++ in accord with Subsection b above.)
++
++ The source code for a work means the preferred form of the work
++ for making modifications to it. For an executable work, 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 executable. However,
++ as a special exception, the source code 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.
++
++ If distribution of executable or 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 counts as distribution of
++ the source code, even though third parties are not compelled to copy
++ the source along with the object code.
++
++ 4. You may not copy, modify, sublicense, or distribute the Program
++ except as expressly provided under this License. Any attempt otherwise
++ to copy, modify, sublicense or distribute the Program 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.
++
++ 5. 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 Program or its derivative works. These actions
++ are prohibited by law if you do not accept this License. Therefore,
++ by modifying or distributing the Program (or any work based on the
++ Program), you indicate your acceptance of this License to do so, and
++ all its terms and conditions for copying, distributing or modifying
++ the Program or works based on it.
++
++ 6. Each time you redistribute the Program (or any work based on the
++ Program), the recipient automatically receives a license from the
++ original licensor to copy, distribute or modify the Program 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 to this License.
++
++ 7. 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 Program at all. For example, if a patent
++ license would not permit royalty-free redistribution of the Program
++ 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 Program.
++
++ 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.
++
++ 8. If the distribution and/or use of the Program is restricted in
++ certain countries either by patents or by copyrighted interfaces, the
++ original copyright holder who places the Program 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.
++
++ 9. The Free Software Foundation may publish revised and/or new versions
++ of the 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 Program
++ 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 Program does not specify
++ a version number of this License, you may choose any version ever
++ published by the Free Software Foundation.
++
++ 10. If you wish to incorporate parts of the Program into other free
++ programs whose distribution conditions are different, 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
++
++ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO
++ WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
++ LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS
++ AND/OR OTHER PARTIES PROVIDE THE PROGRAM "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
++ PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME
++ THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
++
++ 12. 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 PROGRAM 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 PROGRAM (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 PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), 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 Programs
++
++If you develop a new program, and you want it to be of the greatest
++possible use to the public, the best way to achieve this is to make it
++free software which everyone can redistribute and change under these
++terms.
++
++To do so, attach the following notices to the program. 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 program's name and an idea of what it does.>
++
++Copyright (C) <yyyy> <name of author>

++This program is distributed in the hope that it will be useful, but
++WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY

++You should have received a copy of the GNU General Public License along

++51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 , USA.
++
++Also add information on how to contact you by electronic and paper mail.
++
++If the program is interactive, make it output a short notice like this
++when it starts in an interactive mode:
++
++Gnomovision version 69, Copyright (C) year name of author Gnomovision
++comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is
++free software, and you are welcome to redistribute it under certain
++conditions; type `show c' for details.
++
++The hypothetical commands `show w' and `show c' should show the
++appropriate parts of the General Public License. Of course, the commands
++you use may be called something other than `show w' and `show c'; they
++could even be mouse-clicks or menu items--whatever suits your program.
++
++You should also get your employer (if you work as a programmer) or
++your school, if any, to sign a "copyright disclaimer" for the program,
++if necessary. Here is a sample; alter the names:
++
++Yoyodyne, Inc., hereby disclaims all copyright interest in the program
++`Gnomovision' (which makes passes at compilers) written by James Hacker.

++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.>
++

+Subject: [PATCH 16/27] tests: fix prog_info initialization in
+ bpf-obj_get_info_by_fd-prog*
+
+The sys_bpf(BPF_OBJ_GET_INFO_BY_FD, &bpf_prog_get_info_attr, ...) is
+called in a loop. The bpf_prog_get_info_attr.info object is in size 104
+but bpf_prog_get_info_attr.info_len is in size 168. Hence, if the prog
+is jited, the second iteration onwards will have nr_jited_ksyms == 1
+which is asking the kernel to fill the
+bpf_prog_get_info_attr.info.jited_ksyms and it is NULL.
+
+* tests/bpf-obj_get_info_by_fd.c (main): Clear memory beyond prog_info
+at the start of every iteration.
+
+Additional changes:

+Subject: [PATCH 17/27] Merge "<... resumed>" printing
+
+Apparently, it was slightly different with no apparent reason.
+Use a single routine to print this message now.
+
+* defs.h (print_syscall_resume): New function declaration.
+* strace.c (print_event_exit): Replace open-coding of "<... resumed>"
+message printing with a print_syscall_resume() call.
+* syscall.c (syscall_exiting_trace): Likewise.
+(print_syscall_resume): New function.
+* tests/threads-execve.c: Update expected output.

+Date: Tue, 29 Jan 2019 14:40:11 +0100
+Subject: [PATCH 18/27] Use accessors for tcp->s_ent, return a stub struct if
+ it is NULL
+
+Since code paths are non-trivial, it's an attempt to future-proof
+and prevent improper access of tcp->s_ent fields.
+
+* defs.h (struct tcb): Update the description of s_ent field.
+(stub_sysent): New declaration.
+(tcp_sysent, n_args): New macro functions.
+(indirect_ipccall): Use tcp_sysent() instead of tcp->s_ent.
+* ipc.c (SYS_FUNC(ipc)): Use n_args() instead of tcp->s_ent->nargs.
+* linux/alpha/get_syscall_args.c (get_syscall_args): Likewise.
+* linux/bfin/get_syscall_args.c (get_syscall_args): Likewise.
+* linux/hppa/get_syscall_args.c (get_syscall_args): Likewise.
+* linux/ia64/get_syscall_args.c (get_syscall_args): Likewise.
+* linux/microblaze/get_syscall_args.c (get_syscall_args): Likewise.
+* linux/mips/get_syscall_args.c (get_syscall_args): Likewise.
+* linux/sh/get_syscall_args.c (get_syscall_args): Likewise.
+* linux/sh64/get_syscall_args.c (get_syscall_args): Likewise.
+* linux/x86_64/get_syscall_args.c (get_syscall_args): Likewise.
+* linux/xtensa/get_syscall_args.c (get_syscall_args): Likewise.
+* prctl.c (print_prctl_args): Likewise.
+* signal.c (SYS_FUNC(sgetmask)): Likewise.
+* util.c (printargs, printargs_u, printargs_d): Likewise.
+* syscall.c (decode_ipc_subcall, decode_syscall_subcall: Likewise.
+(dumpio, tamper_with_syscall_exiting, syscall_entering_decode,
+syscall_entering_decode, syscall_entering_trace, syscall_entering_trace,
+syscall_exiting_decode, print_syscall_resume, syscall_exiting_trace,
+get_syscall_result): Use tcp_sysent() instead of tcp->s_ent.
+(stub_sysent): New stub sysent.
+(get_scno): Reset scno, s_ent, qual_flg; initialise s->ent from
+stub_sysent.
+* pathtrace.c (pathtrace_match_set): Use tcp_sysent() instead of
+tcp->s_ent.

+Subject: [PATCH 22/27] tests: add kill_child test
+
+This tests repeatedly creates and kills children, so some corner
+cases in handling of not-quite-existing processes can be observed.
+
+Previously, strace was crashing in the following situation:
+
+ 13994 ????( <unfinished ...>
+ ...
+ 13994 <... ???? resumed>) = ?
+
+as tcp->s_ent wasn't initialised on syscall entering and
+strace.c:print_event_exit segfaulted when tried to access
+tcp->s_ent->sys_name.
+
+* tests/kill_child.c: New file.
+* tests/kill_child.test: New test.
+* tests/.gitignore: Add kill_child.
+* tests/Makefile.am (check_PROGRAMS): Likewise.
+(MISC_TESTS): Add kill_child.test.
+
+Skipped files (not present in dist tarball):
+ tests/.gitignore
+
+Additional changes:
+ tests/Makefile.in (auto-generated from tests/Makefile.am)
+ tests-m32/Makefile.in (auto-generated from tests-m32/Makefile.am)
+ tests-m32/kill_child.c (copy of tests/kill_child.c)

++/*
++ * struct list_item and related macros and functions provide an interface
++ * for manipulating and iterating linked lists. In order to have list
++ * associated with its payload, struct list_item has to be embedded into
++ * a structure type representing payload, and (optionally) an additional
++ * struct list_item should be added somewhere as a starting point for list
++ * iteration (creating a list with a designated head). A situation where
++ * no designated head exists, and each embedded struct list_head is considered
++ * a head (i.e. starting point for list iteration), is also possible.
++ *
++ * List head has to be initialised with list_init() call. Statically allocated
++ * list heads can also be defined with an EMPTY_LIST() macro.
++ *
++ * In order to get a pointer to list item from a struct list_item, list_elem
++ * macro is used.
++ *
++ * When a designated head is used, list_head() and list_tail() can be used
++ * for getting pointer to the first and the last list item, respectively.
++ *
++ * list_next() and list_prev() macros can be used for obtaining pointers
++ * to the next and the previous items in the list, respectively. Note that
++ * they do not perform additional checks for the validity of these pointers,
++ * so they have to be guarded with respective list_head/list_tail checks in case
++ * of lists with designated heads (where the list's head is not embedded withing
++ * a list item.
++ *
++ * list_{insert,append,remove,remove_tail,remove_head,replace} provide some
++ * basic means of list manipulation.
++ *
++ * list_foreach() and list_foreach_safe() are wrapper macros for simplifying
++ * iteration over a list, with the latter having an additional argument
++ * for storing temporary pointer, thus allowing list manipulations during
++ * its iteration.
++ *
++ * A simple example:
++ *
++ * struct my_struct {
++ * int a;
++ * struct list_item l1;
++ * struct list_item l2;
++ * };
++ *
++ * EMPTY_LIST(list_1); <--- Defining a designated head for list
++ *
++ * struct my_struct *item =
++ * calloc(1, sizeof(*item));
++ * list_init(&item->l2); <--- Initialising structure field that
++ * is used for lists without designated
++ * head.
++ * list_insert(&list_1, &item->l1); <--- Inserting an item into the list
++ *
++ * item = calloc(1, sizeof(*item));
++ * list_init(&item->l2);
++ *
++ * list_append(&(list_head(list_1, struct my_struct, l1)->l2), &item->l2);
++ *
++ * struct my_struct *cur = item; <--- Iteration over a headless list
++ * do {
++ * printf("%d\n", cur->a);
++ * } while ((cur = list_next(&cur, l2)) != item);
++ *
++ * struct my_struct *i;
++ * list_foreach(i, list_1, l1) { <--- Iteration over list_1 without list
++ * printf("%d\n", i->a); modification
++ * }
++ *
++ * struct my_struct *tmp; <--- Iteration with modification
++ * list_foreach_safe(i, list_1, l1, tmp) {
++ * list_remove(&i->l1);
++ * free(i);
++ * }
++ *

+Subject: [PATCH 27/27] Implement queueing of threads before dispatching them
+
+It is possible that some tracees call a lot of cheap syscalls too fast,
+and that can stress the tracer to the point some tracees are not served
+for indefinite amount of time. In order to avoid that unfairness, try
+to collect all the pending tracees first along with the relevant
+information and only then dispatch the events.
+
+* defs.h: Include "list.h".
+(struct tcb): Add wait_data_idx, delayed_wait_data, and wait_list
+fields.
+* strace.c (struct tcb_wait_data): Add "msg" field.
+(tcb_wait_tab, tcb_wait_tab_size): New static variables.
+(alloctcb): Initialize wait_list.
+(droptcb): Remove tcp from wait_list.
+(maybe_switch_tcbs): Get old pid from
+tcb_wait_tab[tcp->wait_data_idx].msg instead of calling
+ptrace(PTRACE_GETEVENTMSG).
+(trace_wait_data_size, init_trace_wait_data, copy_trace_wait_data,
+free_trace_wait_data, tcb_wait_tab_check_size): New functions, in order
+to allow the code outside next_event to operate with wait_data as with
+an opaque object (needed for dispatch_event and restart_delayed_tcb).
+(next_event): Add pending_tcps, extra_tcp, wait_nohang, elem, and
+wait_tab_pos variables; check for elements in pending_tcps and skip
+waiting if the list is not empty; check for extra_tcp and skip waiting
+along with swapping wait_data_idx with wait_extra_data_idx;
+after the initial wait4(), call wait4() in loop with WNOHANG flag set;
+fetch siginfo on signal and eventmsg on PTRACE_EVENT_EXEC;
+return the first tcp in pending_tcps list.
+(dispatch_event): Store a pointer to a copy of tcb_wait_data in
+tcp->delayed_wait_data if tcp's restart has to be delayed.
+(restart_delayed_tcb): Use tcp->delayed_wait_data, create a stub
+tcb_wait_data if it is NULL, free temporary trace_wait_data.
+* tests/Makefile.am (XFAIL_TEST): Remove looping_threads.test.

-From: "Dmitry V. Levin" <ldv@altlinux.org>
-Date: Tue, 14 Aug 2018 13:43:34 +0000
-Subject: [PATCH] strace.c: introduce struct tcb_wait_data
-
-Introduce a new structure to pass information between next_event(),
-restart_delayed_tcb(), and dispatch_event().
-
-This is going to be used by a subsequent change of next_event().
-
-* strace.c (struct tcb_wait_data): New type.
-(next_event): Remove parameters, return a pointer
-to const struct tcb_wait_data. Return NULL instead of TE_BREAK.
-(dispatch_event): Replace all parameters with a pointer
-to const struct tcb_wait_data, obtain the trace event, siginfo,
-and status from its fields.
-(restart_delayed_tcb): Add local struct tcb_wait_data variable
-with te field set to TE_RESTART, pass it to dispatch_event().
-(main): Remove status and si variables, update next_event()
-and dispatch_event() invocations.

-Subject: [PATCH 3/3] Implement queueing of threads before dispatching them
-
-It is possible that some tracees call a lot of cheap syscalls too fast,
-and that can lead to starvation to the point some tracees are not served
-for indefinite amount of time. In order to solve that unfairness, try
-to collect all the pending tracees first along with the relevant
-information and only then dispatch the events.
-
-* defs.h: Include "list.h".
-(struct tcb): Add wait_data_idx and wait_list fields.
-* strace.c (struct tcb_wait_data): Add "msg" field.
-(tcb_wait_tab): New static variable.
-(expand_tcbtab): Resize tcb_wait_tab along with tcbtab, provide
-an additional slot for extra event.
-(droptcb): Remove tcp from wait_list.
-(maybe_switch_tcbs): Get old pid from
-tcb_wait_tab[tcp->wait_data_idx].msg.
-(next_event): Add pending_tcps, extra_tcp, wait_nohang, elem, and
-wait_tab_pos variables; check for elements in pending_tcps and skip
-waiting if the list is not empty; check for extra_tcp and skip waiting
-along with swapping wait_data_idx with wait_extra_data_idx;
-after the initial wait, call wait4() in loop with WNOHANG flag set;
-fetch siginfo on signal and eventmsg on PTRACE_EVENT_EXEC;
-return the first tcp in pending_tcps list.
-* tests/Makefile.am (XFAIL_TEST): Remove looping_threads.test.
