it's been reported[0] that RHEL7 fails to properly set the length
parameter of the getsockname() call to the length of the required
struct sockaddr type, and always returns the length passed if it
is big enough.
the SOCKADDR_UNION_* macros originate from my microsocks[1] project,
and facilitate handling of the sockaddr mess without nasty casts.

tinyproxy used to do a full hostname resolution whenever a new client
connection happened, which could cause very long delays (as reported in #198).
there's only a single place/scenario that actually requires a hostname, and
that is when an Allow/Deny rule exists for a hostname or domain, rather than
a raw IP address. since it is very likely this feature is not very widely used,
it makes absolute sense to only do the costly resolution when it is unavoidable.

This prepares listenting on multiple sockets, which will be ussed to
fix listening on the wildcard (listen on both ipv6 and ipv4) and
help add the support for multiple Listen statements in the config

instead of using config.ipAddr internally.
This is in preparation to make it possible
to call it for multiple addresses.

This changes listen_sock() to not return the
addrlen of the used address from getaddrinfo call
to the caller, stored in global addrlen in child.c.
This was only used to be able to allocate enough space for the
arguments to the later accept call depending on whether
IPv4 or IPv6 is used.
This removes the need to pass this info by always allocating
sizeof(struct sockaddr_storage) instead, which is enough
to carry both sockaddr_in and sockaddr_in6.

This is a commit which simply ran all C source code files
through GNU indent. No other modifications were made.
|
|
The notices have been changed to a more GNU look. Documentation
comments have been separated from the copyright header. I've tried to
keep all copyright notices intact. Some author contact details have
been updated.

I re-indented the source code using indent with the following options:
indent -kr -bad -bap -nut -i8 -l80 -psl -sob -ss -ncs
There are now _no_ tabs in the source files, and all indentation is
eight spaces. Lines are 80 characters long, and the procedure type is
on it's own line. Read the indent manual for more information about
what each option means.

This allows tinyproxy to respond to a request bound to the same
interface that the request came in on. As Oswald explains:
"attached is a patch that adds the BindSame option. it causes
binding an outgoing connection to the ip address of the respective
incoming connection. that way one can simulate an entire proxy farm
with a single instance of tinyproxy on a multi-homed machine."
Cool.

Also moved safe_write(), safe_read(), readline(), and write_message()
functions into their own file.

passed. Also safe_write() and safe_read() now use char pointer buffers
rather than the void pointer style.

restrictions on the length of a line (unless you fill memory of course.)
Reformated the source.

contains all the code for properly bringing in the system headers (in the
correct order and with proper dependancies.)

Made the sock_mutex static since it's not referenced outside the file.
Changed the data types for some of the variables.
Cleaned up the readline function (changed data types and removed
variables.)
|
|
Added mutex locking around the dnscache() call.
Removed the global sockaddr and setup_fd variables.
Added the socket_blocking() and socket_nonblocking() functions.
Gutted the readling() function and replaced it with something similar to
the 1.0 version. :)
