gdbreplay had its own implementation of fromhex. This patch changes
it to use the one in common/.
gdb/gdbserver/ChangeLog
2019-06-02 Tom Tromey <tom@tromey.com>
* gdbreplay.c (fromhex): Remove.
* Makefile.in (GDBREPLAY_OBS): Add rsp-low.o.
This changeset defines _WIN32_WINNT to at least 0x0501, the level
of Windows XP, unless defined to a higher level, in a single
place. It then removes all the overrides of _WIN32_WINNT in
individual files as no longer needed. Doing this also solves
compilation of windows-nat.c with mingw.org's MinGW, as that
file uses CONSOLE_FONT_INFO which needs the XP level to become
exposed in the Windows headers, while mingw.org defaults to
Windows 9X.

As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header

This patch implements IPv6 support for both GDB and gdbserver. Based
on my research, it is the fourth attempt to do that since 2006. Since
I used ideas from all of the previous patches, I also added their
authors's names on the ChangeLogs as a way to recognize their
efforts. For reference sake, you can find the previous attempts at:
https://sourceware.org/ml/gdb-patches/2006-09/msg00192.htmlhttps://sourceware.org/ml/gdb-patches/2014-02/msg00248.htmlhttps://sourceware.org/ml/gdb-patches/2016-02/msg00226.html
The basic idea behind the patch is to start using the new
'getaddrinfo'/'getnameinfo' calls, which are responsible for
translating names and addresses in a protocol-independent way. This
means that if we ever have a new version of the IP protocol, we won't
need to change the code again (or, at least, won't have to change the
majority of the code).
The function 'getaddrinfo' returns a linked list of possible addresses
to connect to. Dealing with multiple addresses proved to be a hard
task with the current TCP auto-retry mechanism implemented on
ser-tcp:net_open. For example, when gdbserver listened only on an
IPv4 socket:
$ ./gdbserver --once 127.0.0.1:1234 ./a.out
and GDB was instructed to try to connect to both IPv6 and IPv4
sockets:
$ ./gdb -ex 'target extended-remote localhost:1234' ./a.out
the user would notice a somewhat big delay before GDB was able to
connect to the IPv4 socket. This happened because GDB was trying to
connect to the IPv6 socket first, and had to wait until the connection
timed out before it tried to connect to the IPv4 socket.
For that reason, I had to rewrite the main loop and implement a new
method for handling multiple connections. After some discussion,
Pedro and I agreed on the following algorithm:
1) For each entry returned by 'getaddrinfo', we try to open a socket
and connect to it.
2.a) If we have a successful 'connect', we just use that connection.
2.b) If we don't have a successfull 'connect', but if we've got a
ECONNREFUSED (meaning the the connection was refused), we keep track
of this fact by using a flag.
2.c) If we don't have a successfull 'connect', but if we've got a
EINPROGRESS (meaning that the connection is in progress), we perform
a 'select' call on the socket until we have a result (either a
successful connection, or an error on the socket).
3) If tcp_auto_retry is true, and we haven't gotten a successful
connection, and at least one of our attempts failed with
ECONNREFUSED, then we wait a little bit (i.e., call
'wait_for_connect'), check to see if there was a
timeout/interruption (in which case we bail out), and then go back
to (1).
After multiple tests, I was able to connect without delay on the
scenario described above, and was also able to connect in all other
types of scenarios.
I also implemented some hostname parsing functions (along with their
corresponding unit tests) which are used to help GDB and gdbserver to
parse hostname strings provided by the user. These new functions are
living inside common/netstuff.[ch]. I've had to do that since IPv6
introduces a new URL scheme, which defines that square brackets can be
used to enclose the host part and differentiate it from the
port (e.g., "[::1]:1234" means "host ::1, port 1234"). I spent some
time thinking about a reasonable way to interpret what the user wants,
and I came up with the following:
- If the user has provided a prefix that doesn't specify the protocol
version (i.e., "tcp:" or "udp:"), or if the user has not provided
any prefix, don't make any assumptions (i.e., assume AF_UNSPEC when
dealing with 'getaddrinfo') *unless* the host starts with "[" (in
which case, assume it's an IPv6 host).
- If the user has provided a prefix that does specify the protocol
version (i.e., "tcp4:", "tcp6:", "udp4:" or "udp6:"), then respect
that.
This method doesn't follow strictly what RFC 2732 proposes (that
literal IPv6 addresses should be provided enclosed in "[" and "]")
because IPv6 addresses still can be provided without square brackets
in our case, but since we have prefixes to specify protocol versions I
think this is not an issue.
Another thing worth mentioning is the new 'GDB_TEST_SOCKETHOST'
testcase parameter, which makes it possible to specify the
hostname (without the port) to be used when testing GDB and
gdbserver. For example, to run IPv6 tests:
$ make check-gdb RUNTESTFLAGS='GDB_TEST_SOCKETHOST=tcp6:[::1]'
Or, to run IPv4 tests:
$ make check-gdb RUNTESTFLAGS='GDB_TEST_SOCKETHOST=tcp4:127.0.0.1'
This required a few changes on the gdbserver-base.exp, and also a
minimal adjustment on gdb.server/run-without-local-binary.exp.
Finally, I've implemented a new testcase,
gdb.server/server-connect.exp, which is supposed to run on the native
host and perform various "smoke tests" using different connection
methods.
This patch has been regression-tested on BuildBot and locally, and
also built using a x86_64-w64-mingw32 GCC, and no problems were found.

This makes gdbreplay share a bit more code with gdbserver, and paves
the way to share more in future. Including common-defs.h pulls in
defines and headers that gdb and gdbserver assume are always
defined/available too, such as for example _(), ansidecl.h or a set of
system headers. Including that revealed (static vs extern conflict)
gdbreplay had a local copy of perror_with_name (which exited directly
instead of throwing an error). So I removed gdbreplay's local copy,
and then added enough .o files until gdbreplay linked successfully.

Since gnulib alloca module was imported, we can include alloca.h in

This commit moves the inclusion of errno.h to common-defs.h and
removes all other inclusions. Note that prior to this commit
server.h included errno.h protected by "#ifdef HAVE_ERRNO_H".
This protection was added with the Windows CE port, which is
currently broken. Since no other platform needs this, I have
removed the protection and the configury to support it.

Now that we are using the gnulib string.h module, we don't need to
check for string.h or strings.h. This removes the last few checks
from the source and from the configure scripts.

With gnulib's unistd module, we can assume unistd.h is always present, and that
STDIN_FILENO, STDOUT_FILENO, STDERR_FILENO are always defined.
Don't remove unistd.h from GDB's configure.ac, as later tests in the
file use HAVE_UNISTD_H checks.

Right now there are two nightly commits to update a file in the tree
with the current date. One commit is for BFD, one is for gdb.
It seems unnecessary to me to do this twice. We can make do with a
single such commit.
This patch changes gdb in a minimal way to reuse the BFD date -- it
extracts it from bfd/version.h and changes version.in to use the
placeholder string "DATE" for those times when a date is wanted.
I propose removing the cron job that updates the version on trunk, and
then check in this patch.
For release branches, we can keep the cron job, but just tell it to
rewrite bfd/version.h. I believe this is a simple change in the
crontab -- the script will work just fine on this file.
This also moves version.in and version.h into common/, to reflect
their shared status; and updates gdbserver to use version.h besides.
* common/create-version.sh: New file.
* Makefile.in (version.c): Use bfd/version.h, common/version.in,
create-version.sh.
(HFILES_NO_SRCDIR): Use common/version.h.
* version.in: Move to ...
* common/version.in: ... here. Replace date with "DATE".
* version.h: Move to ...
* common/version.h: ... here.
gdbserver:
* Makefile.in (version.c): Use bfd/version.h, common/version.in,
create-version.sh.
(version.o): Remove.
* gdbreplay.c: Include version.h.
(version, host_name): Don't declare.
* server.h: Include version.h.
(version, host_name): Don't declare.
doc:
* Makefile.in (POD2MAN1, POD2MAN5): Use version.subst.

(mostlyclean): Remove version.subst.
Two modifications:
1. The addition of 2013 to the copyright year range for every file;
2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.
gdb/ChangeLog:
* top.c (print_gdb_version): Update copyright year in version output.
gdb/gdbserverChangeLog:
* server.c (gdbserver_version): Update copyright year in version
output.
* gdbreplay.c (gdbreplay_version): Ditto.
This patch moves all includes of malloc.h, which were introduced
purely to get access to alloca's declaration, to server.h, next
to the include of alloca.h.
There is one exception: gdbreplay.c, which does not include server.h.
In this case, the include of alloca.h was simply moved up a bit, next
to the include of malloc.h.
gdb/gdbserver/ChangeLog:
* gdbreplay.c: Move include of alloca.h up, next to include of
malloc.h.
* server.h: Add include of malloc.h.
* mem-break.c: Remove include of malloc.h.
* server.c, tracepoint.c, utils.c, win32-low.c: Likewise.
On LynxOS, alloca is defined in allocal.h. This fixes one warning that
occurs when building GDBserver for LynxOS.
gdb/gdbserver/ChangeLog:
* configure.ac: Add configure check for alloca.
* configure, config.in: Regenerate.
* server.h: Include alloca.h if it exists.
