This removes all traces of dccp, specifically dccp_recv.c and dccp_send.c.
The flowops related functions of net.c can go away as well, as flowops were
only needed for the dccp transport. A few other functions are simplified by
dropping the flowops or protocol parameter.
Further cleanups are possible, but are deferred to subsequent commits. In
particular, some functions of send_common.c are only called by the http
transport now. These can be moved to http_send.c and then be made static.

These just clutter the generated documentation, particularly the list of
global variables.

Every .c file includes it anyway.

Currently we have ~15 error codes which indicate an EOF condition. One
should suffice, so drop all codes except the generic E_EOF and use
that everywhere.

This series implements a new memory allocation API which checks
for overflows. The first part of the series just renames the main
allocation functions. Later patches in the series implement allocators
which take two size_t arguments (like calloc(3)) and check whether the
multiplication overflows by employing the __builtin_mul_overflow()
primitive supported by gcc and clang. This requires us to bump the
lowest supported gcc and clang version.
* refs/heads/t/overflow:
build: Compile with -ftrapv.
string: Introduce arr_zalloc().
string: Introduce arr_alloc().
string: Introduce arr_realloc() and check for integer overflow.
string: Rename para_calloc() -> zalloc().
string: Rename para_malloc() -> alloc().
string: Overhaul para_strdup().

Change all callers of alloc() which pass a product of two integers as
the allocation size to call the new function instead. This function
aborts if the multiplication overflows. With arr_alloc() in place,
alloc() reduces to a trivial wrapper which calls new arr_alloc()
with the first argument equal to one.

Reword the documentation a bit since the function has never been a
wrapper for calloc(3). No code changes.

Just because it's shorter and matches the naming of the new allocators
we are about to introduce. The bulk of this patch was created with
sed -i 's/para_malloc/alloc/g' *.c *.h yy/mp.y

The word "monitor" is neutral and continues to be correct after the
switch from select(2) to poll(2).
Pure rename, nothing to see here.

This preparatory patch for replacing select() renames para_fd_set()
to sched_fd_set(), moves it to sched.c and makes it static. All
users are modified to call either of the two new public functions
sched_monitor_{read,write}fd() which take a pointer to struct sched
rather than an fd set pointer.

Two trivial wrappers for FD_ISSET() which hide the fact that we're
still using the select(2) API.

A bunch of simple patches which streamline the macros and inline
functions of list.h which were taken from linux long ago without
adjusting the coding style.
Cooking for three months.
* refs/heads/t/list-cleanups:
list.h: Convert INIT_LIST_HEAD macro to inline function.
list.h: Fix parameter doc of iterators.
list.h: Move list_is_singular() up.
list.h: Rename argument of list_move().
list.h: Don't use "new" as an variable name.
list.h: Open-code LIST_POISON1 and LIST_POISON2.
list.h: Get rid of internal helpers.
list.h: Trivial cleanups.
list.h: Remove unused list_for_each_entry_safe_reverse.
|

Inline functions are easier to read and write, and we get type
safety.

It's perfectly fine to fail here due to EOF, so don't print a log
message in this case.

The GPLv2 line does not add any additional information, so drop
it. This leaves a single line of legalese text for most files, which
is about the amount of screen real estate it deserves.
This patch was created with the following script (plus some manual
fixups):
awk '{
if (NR <= 5) {
gs = gensub(/.*Copyright.* ([0-9]+).*Andre Noll.*/, "\\1", "g")
if (gs != $0)
year = gs
next
}
if (NR == 6 && year != "")
printf("/* Copyright (C) %s Andre Noll <maan@tuebingen.mpg.de>, see file COPYING. */\n", year)
print
}'

This replaces the *_filter.m4 gengetopt files by the filter_cmd
lopsub suite, where each filter is realized as a subcommand. Due to
this change, para_filter needs to be linked with -llopsub.
The filter structure is now stored in the user_data pointer provided
by lopsub, allowing to get rid of the global filters[] array, the
FILTER_ENUM macro and the corresponding enumeration constants.
The removal of the ->goo_help member of struct filter makes this
structure constant. Hence ->init() of struct filter can also go
away. We still can tell whether a filter is supported by checking
the user_data pointer: if it is NULL, the filter is unsupported. The
new filter_supported() helper in filter_common.c is provided for
convenience.
Parsing of the filter command line options is now performed
generically, and the ->parse_config() method is renamed to ->setup(),
an optional function which is supposed to perform semantic checks
and the one-time setup of the filter, if any. It is accompanied by
->teardown() which replaces ->free_config().
The conversion of the individual filters is easy since most filters
have a simple syntax or take no arguments at all. The resample_filter,
however, needs a different way to copy the wav parameters from the
lopsub parse result to the wav parms structure. A suitable macro,
LLS_COPY_WAV_PARMS is added to check_wav.h for this purpose. The old
COPY_WAV_PARMS needs to stay until para_write, the only other user
of the macro, has been converted as well.
The section heading of the manual page has changed slightly, causing
t0005 to fail. Hence this test needs a slight adjustment.

This should help to understand the lifetime of the various structures
of the sync filter.

Quite a few..

We leaked a struct sync_buddy for every audio file. Freeing the
structure in sync_close_buddy() should close this leak.

The mail server on systemlinux.org was down for more than a week
lately, so let's use an alternative official address. This commit
changes all maan@systemlinux.org addresses to maan@tuebingen.mpg.de.
Most .c and .h files contain the email address in the copyright header,
so they must all be patched. Three other files contain the address
for a different reason:
* README lists email and git, gitweb and home page URLs
* configure.ac needs it for configure -h
* version.c contains it for the -V option of all commands

The patch is large, but it's fairly straight forward: Instead of
a task pointer all ->pre_select() and ->post_select() methods now
receive the context pointer that was passed to the scheduler when
the task was registered. This allows to kill the public task_context().
Two pre_select/post_select functions are not directly called by the
scheduler: session_post_select(), generic_recv_pre_select(). These
are changed to receive a proper struct rather than a void pointer.
Note that generic_filter_pre_select() is not changed in this
manner because some filters do not provide a pre_select wrapper but set
task->pre_select to generic_filter_pre_select().

This adds a new filter for synchronization between clients. It works
by sending an UDP packet to other clients ("buddies").
To reduce latency, address resolution is only performed once on
startup. Hence lookup_address() and makesock_addrinfo() of net.c
are made public.
This commit introduces new public function sockaddr_equal() in
net.c which compares two IPv4 or IPv6 addresses. It is used in
sync_find_buddy().
