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. + + 2000-06-06 Robert James Kaes <rjkaes@flarenet.com> * fixed the links in doc/tinyproxy.8 for locating tinyproxy to - point to the new location at SorceForge.net. Thanks to Simon Baker + point to the new location at SourceForge.net. Thanks to Simon Baker for pointing this out. 2000-04-26 Robert James Kaes <rjkaes@flarenet.com> |
