timegm() is not provided everywhere and the documentation on how to
replace it is bogus as it proposes an inefficient and non-thread safe
alternative.
Here we reimplement everything needed to compute the number of seconds
since Epoch based on the broken down fields in struct tm. It is only
guaranteed to return correct values for correct inputs. It was successfully
tested with all possible 32-bit values of time_t converted to struct tm
using gmtime() and back to time_t using the legacy timegm() and this
function, and both functions always produced the same result.
Thanks to Benoît Garnier for an instructive discussion and detailed
explanations of the various time functions, leading to this solution.
In some cases, the socket is misused. The user can open socket and never
close it, or open the socket and close it without sending data. This
causes resources leak on all resources associated to the stream (buffer,
spoe, ...)
This is caused by the stream_shutdown function which is called outside
of the stream execution process. Sometimes, the shtudown is required
while the stream is not started, so the cleanup is ignored.
This patch change the shutdown mode of the session. Now if the session is
no longer used and the Lua want to destroy it, it just set a destroy flag
and the session kill itself.
This patch should be backported in 1.6 and 1.7
Functions hdr_idx_first_idx() and hdr_idx_first_pos() were missing a
"const" qualifier on their arguments which are not modified, causing
a warning in some experimental H2 code.
When several stick-tables were configured with several peers sections,
only a part of them could be synchronized: the ones attached to the last
parsed 'peers' section. This was due to the fact that, at least, the peer I/O handler
refered to the wrong peer section list, in fact always the same: the last one parsed.
The fact that the global peer section list was named "struct peers *peers"
lead to this issue. This variable name is dangerous ;).
So this patch renames global 'peers' variable to 'cfg_peers' to ensure that
no such wrong references are still in use, then all the functions wich used
old 'peers' variable have been modified to refer to the correct peer list.
Must be backported to 1.6 and 1.7.
When support for passing SNI to the server was added in 1.6-dev3, there
was no way to validate that the certificate presented by the server would
really match the name requested in the SNI, which is quite a problem as
it allows other (valid) certificates to be presented instead (when hitting
the wrong server or due to a man in the middle).
This patch adds the missing check against the value passed in the SNI.
The "verifyhost" value keeps precedence if set. If no SNI is used and
no verifyhost directive is specified, then the certificate name is not
checked (this is unchanged).
In order to extract the SNI value, it was necessary to make use of
SSL_SESSION_get0_hostname(), which appeared in openssl 1.1.0. This is
a trivial function which returns the value of s->tlsext_hostname, so
it was provided in the compat layer for older versions. After some
refinements from Emmanuel, it now builds with openssl 1.0.2, openssl
1.1.0 and boringssl. A test file was provided to ease testing all cases.
After some careful observation period it may make sense to backport
this to 1.7 and 1.6 as some users rightfully consider this limitation
as a bug.

The bug: Maps/ACLs using the same file/id can mistakenly inherit
their flags from the last declared one.
i.e.
$ cat haproxy.conf
listen mylistener
mode http
bind 0.0.0.0:8080
acl myacl1 url -i -f mine.acl
acl myacl2 url -f mine.acl
acl myacl3 url -i -f mine.acl
redirect location / if myacl2
$ cat mine.acl
foobar
Shows an unexpected redirect for request 'GET /FOObAR HTTP/1.0\n\n'.
This fix should be backported on mainline branches v1.6 and v1.7.
The reference of the current map/acl element to dump could
be destroyed if map is updated from an 'http-request del-map'
configuration rule or throught a 'del map/acl' on CLI.
We use a 'back_refs' chaining element to fix this. As it
is done to dump sessions.
This patch needs also fix:
'BUG/MAJOR: cli: fix custom io_release was crushed by NULL.'
To clean the back_ref and avoid a crash on a further
del/clear map operation.
Those fixes should be backported on mainline branches 1.7 and 1.6.
This patch wont directly apply on 1.6.
In order to authorize call of appctx_wakeup on running task:
- from within the task handler itself.
- in futur, from another thread.
The appctx is considered paused as default after running the handler.
The handler should explicitly call appctx_wakeup to be re-called.
When the appctx_free is called on a running handler. The real
free is postponed at the end of the handler process.
This will be used to retrieve the ALPN negociated over SSL (or possibly
via the proxy protocol later). It's likely that this information should
be stored in the connection itself, but it requires adding an extra
pointer and an extra integer. Thus better rely on the transport layer
to pass this info for now.
In order to authorize call of task_wakeup on running task:
- from within the task handler itself.
- in futur, from another thread.
The lookups on runqueue and waitqueue are re-worked
to prepare multithread stuff.
If task_wakeup is called on a running task, the woken
message flags are savec in the 'pending_state' attribute of
the state. The real wakeup is postponed at the end of the handler
process and the woken messages are copied from pending_state
to the state attribute of the task.
It's important to note that this change will cause a very minor
(though measurable) performance loss but it is necessary to make
forward progress on a multi-threaded scheduler. Most users won't
ever notice.
Under certain circumstances, if a stream's task is first woken up
(eg: I/O event) then notified of the availability of a buffer it
was waiting for via stream_res_wakeup(), this second event is lost
because the flags are only merged after seeing that the task is
running. At the moment it seems that the TASK_WOKEN_RES event is
not explicitly checked for, but better fix this before getting
reports of lost events.
This fix removes this "task running" test which is properly
performed in task_wakeup(), while the flags are properly merged.
It must be backported to 1.7 and 1.6.
These functions was added in commit 637f8f2c ("BUG/MEDIUM: buffers: Fix how
input/output data are injected into buffers").
This patch fixes hidden bugs. When a buffer is full (buf->i + buf->o ==
buf->size), instead of returning 0, these functions can return buf->size. Today,
this never happens because callers already check if the buffer is full before
calling bi/bo_contig_space. But to avoid possible bugs if calling conditions
changed, we slightly refactored these functions.
SSL/TLS version can be changed per certificat if and only if openssl lib support
earlier callback on handshake and, of course, is implemented in haproxy. It's ok
for BoringSSL. For Openssl, version 1.1.1 have such callback and could support it.
Very early in the connection rework process leading to v1.5-dev12, commit
56a77e5 ("MEDIUM: connection: complete the polling cleanups") marked the
end of use for this flag which since was never set anymore, but it continues
to be tested. Let's kill it now.
When dumping data at various places in the code, it's hard to figure
what is present where. To make this easier, this patch slightly modifies
debug_hexdump() to take a prefix string which is prepended in front of
each output line.
This patch is a major upgrade of the internal run-time DNS resolver in
HAProxy and it brings the following 2 main changes:
1. DNS resolution task
Up to now, DNS resolution was triggered by the health check task.
From now, DNS resolution task is autonomous. It is started by HAProxy
right after the scheduler is available and it is woken either when a
network IO occurs for one of its nameserver or when a timeout is
matched.
From now, this means we can enable DNS resolution for a server without
enabling health checking.
2. Introduction of a dns_requester structure
Up to now, DNS resolution was purposely made for resolving server
hostnames.
The idea, is to ensure that any HAProxy internal object should be able
to trigger a DNS resolution. For this purpose, 2 things has to be done:
- clean up the DNS code from the server structure (this was already
quite clean actually) and clean up the server's callbacks from
manipulating too much DNS resolution
- create an agnostic structure which allows linking a DNS resolution
and a requester of any type (using obj_type enum)
3. Manage requesters through queues
Up to now, there was an uniq relationship between a resolution and it's
owner (aka the requester now). It's a shame, because in some cases,
multiple objects may share the same hostname and may benefit from a
resolution being performed by a third party.
This patch introduces the notion of queues, which are basically lists of
either currently running resolution or waiting ones.
The resolutions are now available as a pool, which belongs to the resolvers.
The pool has has a default size of 64 resolutions per resolvers and is
allocated at configuration parsing.
Introduction of a DNS response LRU cache in HAProxy.
When a positive response is received from a DNS server, HAProxy stores
it in the struct resolution and then also populates a LRU cache with the
response.
For now, the key in the cache is a XXHASH64 of the hostname in the
domain name format concatened to the query type in string format.
Prior this patch, the DNS responses were stored in a pre-allocated
memory area (allocated at HAProxy's startup).
The problem is that this memory is erased for each new DNS responses
received and processed.
This patch removes the global memory allocation (which was not thread
safe by the way) and introduces a storage of the dns response in the
struct
resolution.
The memory in the struct resolution is also reserved at start up and is
thread safe, since each resolution structure will have its own memory
area.
For now, we simply store the response and use it atomically per
response per server.
In the process of breaking links between dns_* functions and other
structures (mainly server and a bit of resolution), the function
dns_get_ip_from_response needs to be reworked: it now can call
"callback" functions based on resolution's owner type to allow modifying
the way the response is processed.
For now, main purpose of the callback function is to check that an IP
address is not already affected to an element of the same type.
For now, only server type has a callback.
This patch introduces a some re-organisation around the DNS code in
HAProxy.
1. make the dns_* functions less dependent on 'struct server' and 'struct resolution'.
With this in mind, the following changes were performed:
- 'struct dns_options' has been removed from 'struct resolution' (well,
we might need it back at some point later, we'll see)
==> we'll use the 'struct dns_options' from the owner of the resolution
- dns_get_ip_from_response(): takes a 'struct dns_options' instead of
'struct resolution'
==> so the caller can pass its own dns options to get the most
appropriate IP from the response
- dns_process_resolve(): struct dns_option is deduced from new
resolution->requester_type parameter
2. add hostname_dn and hostname_dn_len into struct server
In order to avoid recomputing a server's hostname into its domain name
format (and use a trash buffer to store the result), it is safer to
compute it once at configuration parsing and to store it into the struct
server.
In the mean time, the struct resolution linked to the server doesn't
need anymore to store the hostname in domain name format. A simple
pointer to the server one will make the trick.
The function srv_alloc_dns_resolution() properly manages everything for
us: memory allocation, pointer updates, etc...
3. move resolvers pointer into struct server
This patch makes the pointer to struct dns_resolvers from struct
dns_resolution obsolete.
Purpose is to make the resolution as "neutral" as possible and since the
requester is already linked to the resolvers, then we don't need this
information anymore in the resolution itself.
A couple of new functions to allocate and free memory for a DNS
resolution structure. Main purpose is to to make the code related to DNS
more consistent.
They allocate or free memory for the structure itself. Later, if needed,
they should also allocate / free the buffers, etc, used by this structure.
They don't set/unset any parameters, this is the role of the caller.
This patch also implement calls to these function eveywhere it is
required.
The default len of request uri in log messages is 1024. In some use
cases, you need to keep the long trail of GET parameters. The only
way to increase this len is to recompile with DEFINE=-DREQURI_LEN=2048.
This commit introduces a tune.http.logurilen configuration directive,
allowing to tune this at runtime.
This option exits every workers when one of the current workers die.
It allows you to monitor the master process in order to relaunch
everything on a failure.
For example it can be used with systemd and Restart=on-failure in a spec
file.
This commit remove the -Ds systemd mode in HAProxy in order to replace
it by a more generic master worker system. It aims to replace entirely
the systemd wrapper in the near future.
The master worker mode implements a new way of managing HAProxy
processes. The master is in charge of parsing the configuration
file and is responsible for spawning child processes.
The master worker mode can be invoked by using the -W flag. It can be
used either in background mode (-D) or foreground mode. When used in
background mode, the master will fork to daemonize.
In master worker background mode, chroot, setuid and setgid are done in
each child rather than in the master process, because the master process
will still need access to filesystem to reload the configuration.
This patch adds the support of a maximum of 32 engines
in async mode.
Some tests have been done using 2 engines simultaneously.
This patch also removes specific 'async' attribute from the connection
structure. All the code relies only on Openssl functions.
ssl-mode-async is a global configuration parameter which enables
asynchronous processing in OPENSSL for all SSL connections haproxy
handles. With SSL_MODE_ASYNC set, TLS I/O operations may indicate a
retry with SSL_ERROR_WANT_ASYNC with this mode set if an asynchronous
capable engine is used to perform cryptographic operations. Currently
async mode only supports one async-capable engine.
This is the latest version of the patchset which includes Emeric's
updates :
- improved async fd cleaning when openssl reports an fd to delete
- prevent conn_fd_handler from calling SSL_{read,write,handshake} until
the async fd is ready, as these operations are very slow and waste CPU
- postpone of SSL_free to ensure the async operation can complete and
does not cause a dereference a released SSL.
- proper removal of async fd from the fdtab and removal of the unused async
flag.
This patch adds the global 'ssl-engine' keyword. First arg is an engine
identifier followed by a list of default_algorithms the engine will
operate.
If the openssl version is too old, an error is reported when the option
is used.
This patch changes the stats socket rights for allowing the sending of
listening sockets.
The previous behavior was to allow any unix stats socket with admin
level to send sockets. It's not possible anymore, you have to set this
option to activate the socket sending.
Example:
stats socket /var/run/haproxy4.sock mode 666 expose-fd listeners level user process 4
The current level variable use only 2 bits for storing the 3 access
level (user, oper and admin).
This patch add a bitmask which allows to use the remaining bits for
other usage.
Plan is to add min-tlsxx max-tlsxx configuration, more consistent than no-tlsxx.
This patch introduce internal min/max and replace force-tlsxx implementation.
SSL method configuration is store in 'struct tls_version_filter'.
SSL method configuration to openssl setting is abstract in 'methodVersions' table.
With openssl < 1.1.0, SSL_CTX_set_ssl_version is used for force (min == max).
With openssl >= 1.1.0, SSL_CTX_set_min/max_proto_version is used.
Currently we unconditionally set SSL_OP_CIPHER_SERVER_PREFERENCE [1],
which may not always be a good thing.
The benefit of server side cipher prioritization may not apply to all
cases out there, and it appears that the various SSL libs are going away
from this recommendation ([2], [3]), as insecure ciphers suites are
properly blacklisted/removed and honoring the client's preference is
more likely to improve user experience (for example using SW-friendly
ciphers on devices without HW AES support).
This is especially true for TLSv1.3, which will restrict the cipher
suites to just AES-GCM and Chacha20/Poly1305.
Apache [4], nginx [5] and others give admins full flexibility, we should
as well.
The initial proposal to change the current default and add a
"prefer-server-ciphers" option (as implemented in e566ecb) has been
declined due to the possible security impact.
This patch implements prefer-client-ciphers without changing the defaults.

This patch adds a new stats socket command to modify server
FQDNs at run time.
Its syntax:
set server <backend>/<server> fqdn <FQDN>
This patch also adds FQDNs to server state file at the end
of each line for backward compatibility ("-" if not present).
These encoding functions does general stuff and can be used in
other context than spoe. This patch moves the function spoe_encode_varint
and spoe_decode_varint from spoe to common. It also remove the prefix spoe.
These functions will be used for encoding values in new binary sample fetch.
When we include the header proto/spoe.h in other files in the same
project, the compilator claim that the symbol have multiple definitions:
src/flt_spoe.o: In function `spoe_encode_varint':
~/git/haproxy/include/proto/spoe.h:45: multiple definition of `spoe_encode_varint'
src/proto_http.o:~/git/haproxy/include/proto/spoe.h:45: first defined here
This patch makes backend sections support 'server-template' new keyword.
Such 'server-template' objects are parsed similarly to a 'server' object
by parse_server() function, but its first arguments are as follows:
server-template <ID prefix> <nb | range> <ip | fqdn>:<port> ...
The remaining arguments are the same as for 'server' lines.
With such server template declarations, servers may be allocated with IDs
built from <ID prefix> and <nb | range> arguments.
For instance declaring:
server-template foo 1-5 google.com:80 ...
or
server-template foo 5 google.com:80 ...
would be equivalent to declare:
server foo1 google.com:80 ...
server foo2 google.com:80 ...
server foo3 google.com:80 ...
server foo4 google.com:80 ...
server foo5 google.com:80 ...
When running with multiple process, if some proxies are just assigned
to some processes, the other processes will just close the file descriptors
for the listening sockets. However, we may still have to provide those
sockets when reloading, so instead we just try hard to pretend those proxies
are dead, while keeping the sockets opened.
A new global option, no-reused-socket", has been added, to restore the old
behavior of closing the sockets not bound to this process.
Add the "-x" flag, that takes a path to a unix socket as an argument. If
used, haproxy will connect to the socket, and asks to get all the
listening sockets from the old process. Any failure is fatal.
This is needed to get seamless reloads on linux.
Add a new command that will send all the listening sockets, via the
stats socket, and their properties.
This is a first step to workaround the linux problem when reloading
haproxy.
