12cedc8a	2021-11-17T08:40:40	Fix deadlock in case of evconnlistener_disable() in parallel with callback I've got an issue when stop evconnlistener not in the event_base_loop() thread. evconnlistener_disable() acquired lev->lock, if the same time, user callbacks is runing, the event thread released lock, after callback finished, it try to aquire the lock again, I think this makes conflict: Here is backtraces: thread 1: 0 __lll_lock_wait (futex=futex@entry=0x555555559a60, private=0) at lowlevellock.c:52 1 0x00007ffff7f2a131 in __GI___pthread_mutex_lock (mutex=0x555555559a60) at ../nptl/pthread_mutex_lock.c:115 2 0x00007ffff7f424c9 in evthread_posix_lock (mode=0, lock_=0x555555559a60) at evthread_pthread.c:79 3 0x00007ffff7f7dc12 in listener_read_cb (fd=7, what=2, p=0x5555555599a0) at listener.c:439 4 0x00007ffff7f6d758 in event_persist_closure (base=0x555555559370, ev=0x5555555599d8) at event.c:1645 5 0x00007ffff7f6da60 in event_process_active_single_queue (base=0x555555559370, activeq=0x5555555597e0, max_to_process=2147483647, endtime=0x0) at event.c:1704 6 0x00007ffff7f6e018 in event_process_active (base=0x555555559370) at event.c:1805 7 0x00007ffff7f6e92a in event_base_loop (base=0x555555559370, flags=0) at event.c:2047 8 0x0000555555555449 in main () at test_listen.c:67 thread 2: 0 futex_wait_cancelable (private=<optimized out>, expected=0, futex_word=0x555555559858) at ../sysdeps/nptl/futex-internal.h:183 1 __pthread_cond_wait_common (abstime=0x0, clockid=0, mutex=0x555555559800, cond=0x555555559830) at pthread_cond_wait.c:508 2 __pthread_cond_wait (cond=0x555555559830, mutex=0x555555559800) at pthread_cond_wait.c:638 3 0x00007ffff7f426f3 in evthread_posix_cond_wait (cond_=0x555555559830, lock_=0x555555559800, tv=0x0) at evthread_pthread.c:162 4 0x00007ffff7f70bc5 in event_del_nolock_ (ev=0x5555555599d8, blocking=2) at event.c:2934 5 0x00007ffff7f70748 in event_del_ (ev=0x5555555599d8, blocking=2) at event.c:2821 6 0x00007ffff7f707a1 in event_del (ev=0x5555555599d8) at event.c:2830 7 0x00007ffff7f7d76e in event_listener_disable (lev=0x5555555599a0) at listener.c:343 8 0x00007ffff7f7d6e5 in evconnlistener_disable (lev=0x5555555599a0) at listener.c:325 9 0x00005555555552c3 in disable_thread (arg=0x5555555599a0) at test_listen.c:27 10 0x00007ffff7f27609 in start_thread (arg=<optimized out>) at pthread_create.c:477 11 0x00007ffff7e4e293 in clone () at ../sysdeps/unix/sysv/linux/x86_64/clone.S:95
082941ed	2021-11-24T14:41:33	build: remove inconsistently used x-prefix comparisons Given that these are already used inconsistently with `test` checks, it makes sense to consolidate to not use the x-prefix comparisons at all. In any case, it would be nice to think we no longer have to work around a problem that existed in shells many, many years ago.

9a38bc5f	2021-11-01T10:01:06	evutil: Fix evutil_freeaddrinfo During testing on win32, util/getaddrinfo failed with NULL hint info r = evutil_getaddrinfo("www.google.com", NULL, NULL, &ai); throwing a critical heap exception when evutil_freeaddrinfo is called. This is because of improper use of freeaddrinfo when nodes within the ai structure are allocated using mm_malloc or mm_calloc (EVUTIL_AI_LIBEVENT_ALLOCATED) This adds the flag in apply_socktype_protocol_hack and walks the linked list in evutil_freeaddrinfo removing linked list nodes that are custom allocated before calling freeaddrinfo.

617ba838	2021-01-09T17:19:27	evdns: add max-probe-timeout/probe-backoff-factor settings I recently found that when the network status changed when calling bufferevent_socket_connect_hostname (e.g. switching between several WIFIs), all DNS servers would fail, and the timeout of probe would be very long if there were many DNS requests. I want libevent to support manual setting of MAX_PROBE_TIMEOUT and TIMEOUT_BACKOFF_FACTOR So move hardcoded MAX_PROBE_TIMEOUT and TIMEOUT_BACKOFF_FACTOR into struct, and allow changing them.

2338f27e	2020-08-29T01:15:20	test/regress_dns: fix -Wmaybe-uninitialized Was not noticed since it is reported only with optimization enabled, as stated in gcc(1): The effectiveness of some warnings depends on optimizations also being enabled. For example -Wsuggest-final-types is more effective with link-time optimization and -Wmaybe-uninitialized does not warn at all unless optimization is enabled. And interesting thing is that it is reported only for -O2, not for -O3, that's why I did not catched it in both cmake env that I had: - debug (it has -O0) - release (it has -O3) While autoconf has -O2.

However sanitizers uses atexit handlers to detect leaks, and this will not detect failures in case of exit() will be called from the atexit handlers, fix this by checking status after waitpid().

In case truncated response is received new attempt is done via TCP connection. Added 2 new macros DNS_QUERY_USEVC and DNS_QUERY_IGNTC to force all requests to be done via TCP and to disable switch to TCP in case of truncated responses. Also added possibility for DNS server to listen and receive requests on TCP port. Current implementation of TCP support in DNS server seems rather preliminary and maybe changes after discussion and code review. Fallback to TCP in case of truncated DNS requests is done automatically. To imitate the old behaviour macros DNS_QUERY_IGNTC should be used. To force all DNS requests to be done via TCP one should use the flag DNS_QUERY_USEVC. Names DNS_QUERY_IGNTC, DNS_QUERY_USEVC were chosen to imitate similar flags in c-ares and glibc."

4da9f87c	2020-02-27T16:59:45	evdns: fix a crash when evdns_base with waiting requests is freed Fix undefined behaviour and application crash that might take place in some rare cases after calling evdns_base_free when there are requests in the waiting queue. Current cleanup procedure in evdns_base_free_and_unlock function includes 2 steps: 1. Finish all inflight requests. 2. Finish all waiting requests. During the first step we iterate over each list in req_heads structure and finish all requests in these lists. With current logic finishing an inflight request (function request_finished) removes it from the inflight requests container and forces a wating connection to be sent (by calling evdns_requests_pump_waiting_queue). When these new requests are sent it is possible that they will be inserted to the list in req_heads that we've already cleaned. So in some cases container of the inflight requests is not empty after this procedure and some requests are not finished and deleted. When timeouts for these requests expire evdns_request_timeout_callback is called but corresponding evdns_base has been already deleted which causes undefined behaviour and possible applicaton crash. It is interesting to note that in old versions of libevent such situation was not possible. This bug was introduced by the commit 14f84bbdc77d90b1d936076661443cdbf516c593. Before this commit nameservers were deleted before finishing the requests. Therefore it was not possible that requests from the waiting queue be sent while we finish the inflight requests.

02905413	2016-02-09T18:01:00	Add callback support for error pages The existing error pages are very basic and don't allow for multi-lingual support or for conformity with other pages in a web site. The aim of the callback functionality is to allow custom error pages to be supported for calls to evhttp_send_error() by both calling applications and Libevent itself. A backward-incompatible change has been made to the title of error pages sent by evhttp_send_error(). The original version of the function used the reason argument as part of the title. That might have unforeseen side-effects if it contains HTML tags. Therefore the title has been changed to always use the standard status text. An example of the error callback can be found in this [version](https://github.com/libevent/libevent/files/123607/http-server.zip) of the 'http-server' sample. It will output error pages with very bright backgrounds, the error code using a very large font size and the reason. Closes: #323 (cherr-picked from PR)

evutil: Fix evutil_freeaddrinfo During testing on win32, util/getaddrinfo failed with NULL hint info r = evutil_getaddrinfo("www.google.com", NULL, NULL, &ai); throwing a critical heap exception when evutil_freeaddrinfo is called. This is because of improper use of freeaddrinfo when nodes within the ai structure are allocated using mm_malloc or mm_calloc (EVUTIL_AI_LIBEVENT_ALLOCATED) This adds the flag in apply_socktype_protocol_hack and walks the linked list in evutil_freeaddrinfo removing linked list nodes that are custom allocated before calling freeaddrinfo.

I want libevent to support manual setting of MAX_PROBE_TIMEOUT and TIMEOUT_BACKOFF_FACTOR So move hardcoded MAX_PROBE_TIMEOUT and TIMEOUT_BACKOFF_FACTOR into struct, and allow changing them.

test/regress_dns: fix -Wmaybe-uninitialized Was not noticed since it is reported only with optimization enabled, as stated in gcc(1): The effectiveness of some warnings depends on optimizations also being enabled. For example -Wsuggest-final-types is more effective with link-time optimization and -Wmaybe-uninitialized does not warn at all unless optimization is enabled. And interesting thing is that it is reported only for -O2, not for -O3, that's why I did not catched it in both cmake env that I had: - debug (it has -O0) - release (it has -O3) While autoconf has -O2.

test: detect test failures if atexit handler calls _exit(!0) (sanitizers) tinytest uses another way of detecting test failures, it uses pipe between child and parent, and if the test function in child returns OK it writes OK flag into pipe, and reads it in parent. However sanitizers uses atexit handlers to detect leaks, and this will not detect failures in case of exit() will be called from the atexit handlers, fix this by checking status after waitpid().

http: Merge branch 'http-max_connections-pr-592' @jcoffland: "When the max connection limit is enabled and the limit is reached, the server will respond immediately with 503 Service Unavailable. This can be used to prevent servers from running out of file descriptors. This is better than request limiting because clients may make more than one request over a single connection. Blocking a request does not necessarily close the connection and free up a socket." * http-max_connections-pr-592: test: cover evhttp max connections Added evhttp max simultaneous connection limiting

Merge branch 'evdns-tcp-pr-1004' @seleznevae: "Added support for DNS requests via TCP. By default, requests are done via UDP. In case truncated response is received new attempt is done via TCP connection. Added 2 new macros DNS_QUERY_USEVC and DNS_QUERY_IGNTC to force all requests to be done via TCP and to disable switch to TCP in case of truncated responses. Also added possibility for DNS server to listen and receive requests on TCP port. Current implementation of TCP support in DNS server seems rather preliminary and maybe changes after discussion and code review. Fallback to TCP in case of truncated DNS requests is done automatically. To imitate the old behaviour macros DNS_QUERY_IGNTC should be used. To force all DNS requests to be done via TCP one should use the flag DNS_QUERY_USEVC. Names DNS_QUERY_IGNTC, DNS_QUERY_USEVC were chosen to imitate similar flags in c-ares and glibc." Ok, interfaces looks good, merging to avoid stalling it for too long. * evdns-tcp-pr-1004: evdns: fix coding style issues evdns: fix trailing whitespaces evdns: bufferevent_setcb before bufferevent_free is redundant evdns: Implement dns requests via tcp

Add wepoll support to light up the epoll backend on Windows libevent is lacking a scalable backend on Windows. Let's leverage the wepoll library until Windows comes up with an epoll/kqueue compete user mode API. - All regress tests pass for standard wepoll - These 2 tests fail intermittently for changelist wepoll, so disabling changelist wepoll for now http/cancel_inactive_server http/stream_in - verify target on Windows runs tests for both wepoll and win32 backends - wepoll backend preferred over win32 backend - wepoll version 1.5.6 v2: cleaner backend abstraction. Disallow wepoll on MinGW/Cygwin. v3: Add wepoll.h to dist v4: Make sure wepoll source files are excluded from cygwin/mingw builds v5: Keep win32 as default backend on windows. v6: Include wepoll in mingw builds. Verified that regress tests pass w/ WEPOLL backend. v7: Enable wepoll on mingw when building with cmake v8: Add wepoll testrunner for autotools test target

Fix EV_CLOSED detection/reporting (epoll only) - EV_CLOSED is EPOLLRDHUP in epoll - EPOLLRDHUP reported w/o EPOLLHUP if the socket closed with shutdown(SHUT_WR) - EPOLLRDHUP reported w/ EPOLLHUP if the socket closed with close() so in this case epoll backend will detect this event as error (EV_READ|EV_WRITE), since the epoll_ctl() will return EPOLLRDHUP with EPOLLHUP set, but this is not correct, let's fix this. Fixes: #984

evdns: fix a crash when evdns_base with waiting requests is freed Fix undefined behaviour and application crash that might take place in some rare cases after calling evdns_base_free when there are requests in the waiting queue. Current cleanup procedure in evdns_base_free_and_unlock function includes 2 steps: 1. Finish all inflight requests. 2. Finish all waiting requests. During the first step we iterate over each list in req_heads structure and finish all requests in these lists. With current logic finishing an inflight request (function request_finished) removes it from the inflight requests container and forces a wating connection to be sent (by calling evdns_requests_pump_waiting_queue). When these new requests are sent it is possible that they will be inserted to the list in req_heads that we've already cleaned. So in some cases container of the inflight requests is not empty after this procedure and some requests are not finished and deleted. When timeouts for these requests expire evdns_request_timeout_callback is called but corresponding evdns_base has been already deleted which causes undefined behaviour and possible applicaton crash. It is interesting to note that in old versions of libevent such situation was not possible. This bug was introduced by the commit 14f84bbdc77d90b1d936076661443cdbf516c593. Before this commit nameservers were deleted before finishing the requests. Therefore it was not possible that requests from the waiting queue be sent while we finish the inflight requests.

Add callback support for error pages The existing error pages are very basic and don't allow for multi-lingual support or for conformity with other pages in a web site. The aim of the callback functionality is to allow custom error pages to be supported for calls to evhttp_send_error() by both calling applications and Libevent itself. A backward-incompatible change has been made to the title of error pages sent by evhttp_send_error(). The original version of the function used the reason argument as part of the title. That might have unforeseen side-effects if it contains HTML tags. Therefore the title has been changed to always use the standard status text. An example of the error callback can be found in this [version](https://github.com/libevent/libevent/files/123607/http-server.zip) of the 'http-server' sample. It will output error pages with very bright backgrounds, the error code using a very large font size and the reason. Closes: #323 (cherr-picked from PR)
