2000-08-23 Robert James Kaes <rjkaes@flarenet.com>
* src/utils.c (pidfile_create): Improved the security of this
function. Prevents cracker abuse of the pid file creation.
* sec/ternary.c: Overhauled to improve the robustness of the code.
Prevents people from effecting the internal system from outside
the official API. I think this is a good example of how all the
functions should be coded. It is a little more complex, but it
handles "problems" much better.
2000-08-21 Robert James Kaes <rjkaes@flarenet.com>
* src/utils.c (strlcat)
* src/utils.c (strlcpy): Added these two functions which take their
API from the OpenBSD versions. Replaces strncpy/strncat.
2000-08-17 Robert James Kaes <rjkaes@flarenet.com>
* src/ternary.c: Added a ternary tree module to replace the uses
of hashes in the source. There _were_ two different hash methods
before, which have been replaced with this general purpose module.
2000-08-12 Robert James Kaes <rjkaes@flarenet.com>
* src/log.c (log): Removed the static variables by changing them to
automatic.
2000-08-03 Robert James Kaes <rjkaes@flarenet.com>
* doc/tinyproxy.8: Updated the manual documentation to match what
tinyproxy actually does. :)
* src/grammar.y: Finished handling the various config keywords.
2000-08-02 Robert James Kaes <rjkaes@flarenet.com>
* src/tinyproxy.c (main): Fixed the change user/group ability.
2000-07-31 Robert James Kaes <rjkaes@flarenet.com>
* src/reqs.c (process_method): Trying to change to a 1.1 compliant
browser. So, the Host header is set and sent. Also, tinyproxy doesn't
handle persistent connections, so tinyproxy needs to send the
Connection: close header.
2000-07-30 Robert James Kaes <rjkaes@flarenet.com>
* src/thread.c (thread_main_loop): Added in the controls for handling
the creating and destruction of threads based on their numbers.
This is used for load control. Adjust MaxSpareServers, MinSpareServers,
and MaxClients.
2000-07-29 Robert James Kaes <rjkaes@flarenet.com>
* src/acl.c: Added the ACL control system. This is much more advanced
then the simple one IP address test. Read doc/tinyproxy.conf for
more information.
2000-07-22 Robert James Kaes <rjkaes@flarenet.com>
* src/log.h: Paired down the logging levels and provided a
description for each level. Please try to be consistent with
these. Also, added the two DEBUG?() function macros for use with
debugging.
* src/thread.c (thread_pool_create): Make sure we don't try to start
more than MaxClients servers.
* src/tinyproxy.c (main): Log when tinyproxy is using default
values rather than specified ones.
* src/reqs.c (relay_connection): Fixed a few difftime() problems
where the two arguments were being reversed.
(relay_connection): Added logging to handle if an Idle Timeout
occured on a connection.
2000-07-19 Robert James Kaes <rjkaes@flarenet.com>
* src/tinyproxy.c (main): Cleaned up the command line arguments
since we now have a configuration file. See grammar.y and
scanner.l for more information.
(versiondisp): Moved the version information out of usagedisp().
2000-07-11 Robert James Kaes <rjkaes@flarenet.com>
* src/utils.c (pidfile_create): Moved from tinyproxy.c
* src/thread.c: Moved all the thread creation code into a seperate
file.
2000-07-10 Robert James Kaes <rjkaes@flarenet.com>
* src/tinyproxy.c (pidfile_create): All the process to write it's
PID to the specified file.
(thread_main, thread_make): Instread of creating a new thread on
each connection, we now have a pool of threads. Right now the pool
is hard coded, but I'd like to have a system similar to Apache
where the pool can change as demand changes.
* src/sock.c (getpeer_string): Needed to add locking around the call
to gethostbyname(). Could use gethostbyname_r() but I can't find a
consistent definition for the function.
2000-07-03 Robert James Kaes <rjkaes@flarenet.com>
* src/reqs.c (safe_write): Added safe_write so that EINTR errors
would be handled correctly when trying to write on a blocking
socket. Non blocking is already handled in the writebuff function.
(safe_read): Matched pair for safe_write(). Same reason.
(pull_client_data): Removed the malloc of the length, and switched
to a fixed buffer. This prevents a DoS where the client specifies
a HUGE buffer and exhausted memory.
2000-07-01 Robert James Kaes <rjkaes@flarenet.com>
* src/reqs.c: Added the ability for sheding connections due to high
system load.
* src/buffer.c (readbuff): Now you can not have a buffer larger
than MAXBUFFSIZE. The read() function will attempt to read in
MAXBUFFSIZE - buffer_size().
* src/tinyproxy.h (MAXBUFFSIZE): This is the main control for all
the buffers in tinyproxy. Currently it is set to 48K since that is
nicely divisable by 2 and 3. The key is by 3 since this give
you 16K which is more than enough for a header line.
* src/stats.c: New file to handle the statistic functions. Needed
since with multiple threads, there has to be some locking around
any changes to the values. Moved the showstats() function here from
utils.c since logically it should be with the other stats routines.
* src/tinyproxy.c (main): Removed the USR1 signal since
LinuxThreads on a libc5 system needs the USR1 and USR2 for internal
processing. This means the USR1 signal dump stats is removed.
* src/reqs.c (handle_connection): Log incoming connections here so
that the information is logged even if we are doing an upstream
relay.
* src/tinyproxy.h: Moved all the common header files here to help
remove the clutter from all the other source files. Removed the
references to client_header and server_header from struct conn_s
since they are no longer used.
* src/reqs.c (validuser): Had the test for a valid user in reverse.
Fixed.
* src/tinyproxy.c (main): Moved the getreqs() function back into
the main function.
2000-06-30 Robert James Kaes <rjkaes@flarenet.com>
* src/dnscache.c (dnscache): Added back the garbage collection
phase of the DNS caching system. Also, cleaned up the source so
only dnscache() is exposed to the rest of the system.
* src/buffer.c: Moved the structure definitions into src/buffer.c
from src/buffer.h. Removed *_buffer() functions. Made buffer_size()
a function so the structure definition does not need to be included
in the header. Removed the references to working_string and
working_length in struct buffer_s since it is no longer needed.
* configure.in: Added the checks for various "standard" data types.
Cleaned up the source, and fixed a problem with SOCKs support.
* acinclude.m4: Added the AC_UNP_CHECK_TYPE macro from
Unix Network Programming, W. Richard Stevens.
* src/reqs.c (handle_connection): Added the UPSTREAM_PROXY code
back into tinyproxy. It uses GOTOs, but it doesn't create spaghetti
code, at least it better not! :)
* src/utils.h:
* src/utils.c: Removed the xmalloc and xstrdup functions since they
really did not add anything to the standard malloc and strdup
functions.
* (all) Went through and removed all the references to xmalloc and
xstrdup. Still need to add the error checking to all these calls
though.
2000-06-29 Robert James Kaes <rjkaes@flarenet.com>
* src/sock.c (opensock): Added mutex locking around the call to
dnscache since I don't want more than one thread to be adding to
the linked list.
* configure.in: moved the tests for USE_PROC, UPTIME_PATH,
DEFAULT_CUTOFFLOAD, DEFAULT_STATHOST from src/config.h
* src/tinyproxy.c: Moved the LOAD_RECALCTIMER define from
src/config.h
* src/reqs.c (handle_method, process_server_headers,
handle_connection):
Handle simple and HTTP/0.9 requests properly.
* src/buffer.h: Changed the default MAXBUFFSIZE to 24 KB.
2000-06-28 Robert James Kaes <rjkaes@flarenet.com>
* src/sock.c (listen_sock): This replaces the init_listen_sock
function and removed the global sockaddr and setup_fd variables.
* src/tinyproxy.c (getreqs): Not at all like the old function by the
same name. This just blocks on accept for new connections and then
creates a new thread for each connection.
* src/tinyproxy.h: Moved the struct conn_s into this header so
we can completely remove the src/conns.h and src/conns.c files as
they are no longer needed.
* src/reqs.c (process_server_headers): Handle server headers
separately from relay_connection since we'll need to be able to read
them in the future if we want to support caching.
(process_client_headers): Check for the Content-Length header. If
it is present then we need to read in all the client's data before
we can process any server headers or send back an error message.
(pull_client_header): Read in Content-Length number of bytes from
the client.
2000-06-27 Robert James Kaes <rjkaes@flarenet.com>
* src/sock.c (socket_blocking, socket_nonblocking): Added the
functions since we need to selectively change a socket's state as
the program runs.
(opensock): Removed the call for making the socket nonblocking since
it should only be switched into nonblocking when it's absolutely
needed.
* src/buffer.c (readbuff, writebuff): Added tests at the beginning of
the functions to return if the limits on the buffer size have been
exceeded. Maybe this should be an assert instead, since these
functions should not be called with exceeded limits.
* src/config.h: Moved this to ./config.h instead. Updated the source
to reflect this change.
* src/log.c: Added logging levels which are duplicates of the syslog
levels. Helps to make the logfile a little easier to parse. This
also means all the calls to log(...) needed to be changed to
log(level, ...)
2000-06-26 Robert James Kaes <rjkaes@flarenet.com>
* src/sock.c (readline): Completely gutted the function and replaced
it with a simpler function which is very similar to the original
function back in version 1.0. :) We can reuse this function again
since the sockets are now blocking again.
2000-06-22 Robert James Kaes <rjkaes@flarenet.com>
* src/reqs.c: A _MASSIVE_ rewrite of the whole connection process.
The old state machine is now gone. Each new connection is now a
separate thread. This allows the sockets to be blocking most of
the time, which made the rest of the functions a lot easier to
code. Some functions have been renamed and a bunch are new. The
changes are really too numerous to list, but the main idea is that
there is a separate function to handle each part of a connection and
the non-blocking code is only needed in the relay_connection
function. Take a look at the code, it's a lot easier to understand
now.
2000-06-21 Robert James Kaes <rjkaes@flarenet.com>
* src/dnscache.h:
* src/dnscache.c: Renamed the functions lookup and insert to
dns_lookup and dns_insert.
(dns_lookup): Cleaned up the code to make it more streamlined.
