As shown in GH #2608 and ("BUG/MEDIUM: proxy: fix email-alert invalid
free"), simply calling free_email_alert() from free_proxy() is not the
right thing to do.
In this patch, we reuse proxy->email_alert.set memory space to introduce
proxy->email_alert.flags in order to support 2 flags:
PR_EMAIL_ALERT_SET (to mimic proxy->email_alert.set) and
PR_EMAIL_ALERT_RESOLVED (set once init_email_alert() was called on the
proxy to resolve email_alert.mailer pointer).
Thanks to PR_EMAIL_ALERT_RESOLVED flag, free_email_alert() may now
properly handle the freeing of proxy email_alert settings: if the RESOLVED
flag is set, then it means the .email_alert.mailers.name parsing hint was
replaced by the actual mailers pointer, thus no free should be attempted.
No backport needed: as described in ("BUG/MEDIUM: proxy: fix email-alert
invalid free"), this historical leak is not sensitive as it cannot be
triggered during runtime.. thus given that the fix is not backport-
friendly, it's not worth the trouble.
AWSLC lacks the SSL_CTX_set1_sigalgs_list define, however the function
exists, which disables the feature in HAProxy, even if we could have
build with it.
SSL_CTX_set1_client_sigalgs_list() is not available, though.
This patch introduce the define so the feature is enabled.
hlua burst timeout was introduced in 58e36e5b1 ("MEDIUM: hlua: introduce
tune.lua.burst-timeout").
It is a safety measure that allows to detect when too much time is spent
on a single lua execution (between 2 interruptions/yields), meaning that
the current thread is not able to perform other tasks. Such scenario
should be avoided because it will cause thread contention which may have
negative performance impact and could cause the watchdog to trigger. When
the burst timeout is exceeded, the current Lua execution is aborted and a
timeout error is reported to the user.
Unfortunately, the same error is currently being reported for cumulative
(AKA execution) timeout and for burst timeout, which may be confusing to
the user.
Indeed, "execution timeout" error historically results from the current
hlua context exceeding the total (cumulative) time it's allowed to run.
It is set per lua context using the dedicated tunables:
- tune.lua.session-timeout
- tune.lua.task-timeout
- tune.lua.service-timeout
We've already faced an user report where the user was able to trigger the
burst timeout and got "Lua task: execution timeout." error while the user
didn't set cumulative timeout. Thus the error was actually confusing
because it was indeed the burst timeout which was causing it due to the
use of cpu-intensive call from within the task without sufficient manual
"yield" keypoints around the cpu-intensive call to ensure it runs on a
dedicated scheduler cycle.
In this patch we make it so burst timeout related errors are reported as
"burst timeout" errors instead of "execution timeout" errors (which
in fact became the generic timeout errors catchall with 58e36e5b1).
To do this, hlua_timer_check() now returns a different value depending if
the exeeded timeout is the burst one or the cumulative one, which allows
us to return either HLUA_E_ETMOUT or HLUA_E_BTMOUT in hlua_ctx_resume().
It should improve the situation described in GH #2356 and may possibly be
backported with 58e36e5b1 to improve error reporting if it applies without
resistance.
AWS-LC have a lot of functions that does nothing, which are now
deprecated and emits some warning.
This patch disables the following useless functions that emits a warning:
SSL_CTX_get_security_level(), SSL_CTX_set_tmp_dh_callback(),
ERR_load_SSL_strings(), RAND_keep_random_devices_open()
The list of deprecated functions is here:
https://github.com/aws/aws-lc/blob/main/docs/porting/functionality-differences.md
AWS-LC does not support the SSL_CTX_set_client_hello_cb() function from
OpenSSL which allows to analyze ciphers and signatures algorithm of the
ClientHello. However it supports the SSL_CTX_set_select_certificate_cb()
which allows the same thing but was the implementation from the
boringSSL side.
This patch uses the SSL_CTX_set_select_certificate_cb() as well as the
SSL_early_callback_ctx_extension_get() function to get the signature
algorithms.
This was successfully tested with openssl s_client as well as
testssl.sh.
This should allow to enable more reg-tests that depend on certificate
selection.
Require at least AWS-LC 1.22.0.
Move the code which is used to select the final certificate with the
clienthello callback. ssl_sock_client_sni_pool need to be exposed from
outside ssl_sock.c
This patch implements prerequisite log-profile struct and parser logic.
It has no effect during runtime for now.
Logformat expressions provided in log-profile "steps" are postchecked
during postparsing for each proxy "log" directive that makes use of a
given profile. (this allows to ensure that the logformat expressions
used in the profile are compatible with proxy using them)
Logger struct may benefit from having a "flags" struct member to set
or remove different logger states. For that, we reuse an existing
4 bytes hole in the logger struct to store a 2 bytes flags integer,
leaving the struct with a 2-bytes hole now.
Prerequisite work for log-profiles, we need to know under which proxy
context the logger is being used. When the info is not available, (ie:
global section or log-forward section, <px> is set to NULL)
'%OG' logformat alias may be used to report the log origin (when/where)
that triggered log generation using sess_build_logline().
Possible values are:
- "sess_error": log was generated during session error handling
- "sess_killed": log was generated during session abortion (killed
embryonic session)
- "txn_accept": log was generated right after frontend conn was accepted
- "txn_request": log was generated after client request was received
- "txn_connect": log was generated after backend connection establishment
- "txn_response": log was generated during server response handling
- "txn_close": log was generated at the final txn step, before closing
- "unspec": unknown or not specified
Documentation was updated.
This is another prerequisite work in preparation for log-profiles: in this
patch we make process_send_log() aware of the log origin, primarily aiming
for sess and txn logging steps such as error, accept, connect, close, as
well as relevant sess and stream pointers.
Move the embryonic session logging logic down to sess_log() in preparation
for log-profiles because then log preferences will be set per logger and
not per proxy. Indeed, as each logger may come with its own log-profile
that possibly overrides proxy logformat preferences, the check will need
to be performed at a central place by lower sending functions.
To ensure the change doesn't break existing behavior, a dedicated
sess_log_embryonic() wrapper was added and is exclusively used by
session_kill_embryonic() to indicate that a special logging logic must
be performed under sess_log().
Also, thanks to this change, log-format-sd will now be taken into account
for legacy embryonic session logging.
rename session_build_err_string() to session_embryonic_build_legacy_err()
and add new <out> buffer argument to the prototype. <out> will be used as
destination for the generated string instead of implicitly relying on the
trash buffer. Finally, expose the new function through the header file so
that it becomes usable from any source file.
The function is expected to be called with a session originating from
a connection and should not be used for applets.
This commit looks messy, but all it does is reorganize send_log() helpers
by dependency order to remove the need of forward-declaring some of them.
Also, since they're all internal helpers, let's explicitly mark them as
static to prevent any misuse.
qc_build_pkt() error handling was difficult due to multiple error code
possible. Improve this by defining a proper enum to describe the various
error code. Also clean up ending labels inside qc_build_pkt().
The previous fix (792a645ec2 ["BUG/MEDIUM: mux-quic: Unblock zero-copy
forwarding if the txbuf can be released"]) introduced a regression. The
zero-copy data forwarding must only be unblocked if it was blocked by the
producer, after a successful negotiation.
It is important because during a negotiation, the consumer may be blocked
for another reason. Because of the flow control for instance. In that case,
there is not necessarily a TX buffer. And it unexpected to try to release an
unallocated TX buf.
In addition, the same may happen while a TX buf is still in-use. In that
case, it must also not be released. So testing the TX buffer is not the
right solution.
To fix the issue, a new IOBUF flag was added (IOBUF_FL_FF_WANT_ROOM). It
must be set by the producer if it is blocked after a sucessful negotiation
because it needs more room. In that case, we know a buffer was provided by
the consummer. In done_fastfwd() callback function, it is then possible to
safely unblock the zero-copy data forwarding if this flag is set.
This patch must be backported to 3.0 with the commit above.
Valentine noticed this ugly SSL_CTX_get_tlsext_status_cb() macro
definition inside ssl_sock.c that is dedicated to openssl-1.0.2 only.
It would be better placed in openssl-compat.h, which is what this
patch does. It also addresses a missing pair of parenthesis and
removes an invalid extra semicolon.
In 2.9 we started to introduce an ambiguity in the documentation by
referring to historical log-format variables ('%var') as log-format
tags in 739c4e5b1e ("MINOR: sample: accept_date / request_date return
%Ts / %tr timestamp values") and 454c372b60 ("DOC: configuration: add
sample fetches for timing events").
In fact, we've had this confusion between log-format tag and log-format
var for more than 10 years now, but in 2.9 it was the first time the
confusion was exposed in the documentation.
Indeed, both 'log-format variable' and 'log-format tag' actually refer
to the same feature (that is: '%B' and friends that can be used for
direct access to some log-oriented predefined fetches instead of using
%[expr] with generic sample expressions).
This feature was first implemented in 723b73ad75 ("MINOR: config: Parse
the string of the log-format config keyword") and later documented in
4894040fa ("DOC: log-format documentation"). At that time, it was clear
that we used to name it 'log-format variable'.
But later the same year, 'log-format tag' naming started to appear in
some commit messages (while still referring to the same feature), for
instance with ffc3fcd6d ("MEDIUM: log: report SSL ciphers and version
in logs using logformat %sslc/%sslv").
Unfortunately in 2.9 when we added (and documented) new log-format
variables we officially started drifting to the misleading 'log-format
tag' naming (perhaps because it was the most recent naming found for
this feature in git log history, or because the confusion has always
been there)
Even worse, in 3.0 this confusion led us to rename all 'var' occurrences
to 'tag' in log-format related code to unify the code with the doc.
Hopefully William quickly noticed that we made a mistake there, but
instead of reverting to historical naming (log-format variable), it was
decided that we must use a different name that is less confusing than
'tags' or 'variables' (tags and variables are keywords that are already
used to designate other features in the code and that are not very
explicit under log-format context today).
Now we refer to '%B' and friends as a logformat alias, which is
essentially a handy way to print some log oriented information in the
log string instead of leveraging '%[expr]' with generic sample expressions
made of fetches and converters. Of course, there are some subtelties, such
as a few log-format aliases that still don't have sample fetch equivalent
for historical reasons, and some aliases that may be a little faster than
their generic sample expression equivalents because most aliases are
pretty much hardcoded in the log building function. But in general
logformat aliases should be simply considered as an alternative to using
expressions (with '%[expr']')
Also, under log-format context, when we want to refer to either an alias
('%alias') or an expression ('%[expr]'), we should use the generic term
'logformat item', which in fact designates a single item within the
logformat string provided by the user. Indeed, a logformat item (whether
is is an alias or an expression) always starts with '%' and may accept
optional flags / arguments
Both the code and the documentation were updated in that sense, hopefully
this will clarify things and prevent future confusions.
Implement pool-conn-name support for idle connection reuse. It replaces
SNI as arbitrary identifier for connections in the idle pool. Thus,
every SNI reference in this context have been replaced.
Main change occurs in connect_server() where pool-conn-name sample fetch
is now prehash to generate idle connection identifier. SNI is now solely
used in the context of SSL for ssl_sock_set_servername().
Define a new server keyword pool-conn-name. The purpose of this keyword
will be to identify connections inside the idle connections pool,
replacing SNI in case SSL is not wanted.
This keyword uses a sample expression argument. It thus can reuse
existing function parse_srv_expr() for parsing. In the future, it may be
necessary to define a keyword variant which uses a logformat for
extensability.
This patch only implement parsing. Argument is stored inside new server
field <pool_conn_name> and expression is generated in
_srv_parse_finalize() into <pool_conn_name_expr>.
If pool-conn-name is not set but SNI is, the latter is reused
automatically as pool-conn-name via _srv_parse_finalize(). This ensures
current reuse behavior remains compatible and idle connection reuse will
not mix connections with different SNIs by mistake.
Main usage will be for rhttp when SSL is not wanted between the two
haproxy instances. Previously, it was possible to use "sni" keyword even
without SSL on a server line which have a similar effect. However,
having a dedicated "pool-conn-name" keyword is deemed clearer. Besides,
it would allow for more complex configuration where pool-conn-name and
SNI are use in parallel with different values.
Two functions exists for server sni sample expression parsing. This is
confusing so this commit aims at clarifying this.
Functions are renamed with the following identifiers. First function is
named parse_srv_expr() and can be used during parsing. Besides
expression parsing, it has ensure sample fetch validity in the context
of a server line.
Second function is renamed _parse_srv_expr() and is used internally by
parse_srv_expr(). It only implements sample parsing without extra
checks. It is already use for server instantiation derived from
server-template as checks were already performed. Also, it is now used
in http-client code as SNI is a fixed string.
Finally, both functions are generalized to remove any reference to SNI.
This will allow to reuse it to parse other server keywords which use an
expression. This will be the case for the future keyword pool-conn-name.
Review RFC 9000 and ensure restriction on Stateless reset are properly
enforced. After careful examination, several changes are introduced.
First, redefine minimal Stateless Reset emitted packet length to 21
bytes (5 random bytes + a token). This is the new default length used in
every case, unless received packet which triggered it is 43 bytes or
smaller.
Ensure every Stateless Reset packets emitted are at 1 byte shorter than
the received packet which triggered it. No Stateless reset will be
emitted if this falls under the above limit of 21 bytes. Thus this
should prevent looping issues.
This should be backported up to 2.6.
This commit introduces a new global setting named
harden.reject_privileged_ports.{tcp|quic}. When active, communications
with clients which use privileged source ports are forbidden. Such
behavior is considered suspicious as it can be used as spoofing or
DNS/NTP amplication attack.
Value is configured per transport protocol. For each TCP and QUIC
distinct code locations are impacted by this setting. The first one is
in sock_accept_conn() which acts as a filter for all TCP based
communications just after accept() returns a new connection. The second
one is dedicated for QUIC communication in quic_recv(). In both cases,
if a privileged source port is used and setting is disabled, received
message is silently dropped.
By default, protection are disabled for both protocols. This is to be
able to backport it without breaking changes on stable release.
This should be backported as it is an interesting security feature yet
relatively simple to implement.
Just like vma_set_name() from 51a8f134e ("DEBUG: tools: add vma_set_name()
helper"), but also takes <id> as parameter to append "-$id" suffix after
the name in order to differentiate 2 areas that were named using the same
<type> and <name> combination.
example, using mmap + MAP_SHARED|MAP_ANONYMOUS:
7364c4fff000-736508000000 rw-s 00000000 00:01 3540 [anon_shmem:type:name-id]
Another example, using mmap + MAP_PRIVATE|MAP_ANONYMOUS or using
glibc/malloc() above MMAP_THRESHOLD:
7364c4fff000-736508000000 rw-s 00000000 00:01 3540 [anon:type:name-id]
On todays large systems, it's not always desired to run on all threads
for light loads, and usually users enforce nbthread to a lower value
(e.g. 8). The problem is that this is a fixed value, and moving such
configs to smaller machines continues to enforce the value and this
becomes extremely unproductive due to having more threads than CPUs.
This also happens quite a bit in VMs, containers, or cloud instances
of various sizes.
This commit introduces the thread-hard-limit setting that allows to only
set an upper bound to the number of threads without raising a lower value.
This means that using "thread-hard-limit 8" will make sure that no more
than 8 threads will be used when available, but it will remain two when
run on a dual-core machine.
As diagnosed in GH issue #2569, there's currently an issue in LibreSSL's
CHACHA20 in-place implementation that makes haproxy discard incoming QUIC
packets encrypted with it. It's not very easy to observe the issue because:
- QUIC recommends that CHACHA20 is used in priority
- on x86 with AES-NI, LibreSSL prefers AES-GCM for performance
reasons, so the problem is only observed there if a client
explicitly forces TLS_CHACHA20_POLY1305_SHA256 only.
- discarded packets cause retransmits showing some apparent activity,
and the handshake succeeds so it's not easy to analyze from the
client which thinks that the server is slow to respond.
Thus in practice, on non-x86 machines running LibreSSL, requests made over
QUIC freeze for a long time, unless the client explicitly forces algos
excluding TLS_CHACHA20_POLY1305_SHA256. That's typically the case by
default on modern OpenBSD systems, and was reported in the issue above
for an arm64 machine running OpenBSD -current, and was also observed on a
mips64 one running OpenBSD 7.5.
There is no simple solution to this problem due to some of the protocol's
constraints without digging too low into the stack (and risking to break
more). Here we're taking a pragmatic approach consisting in making the
connection fail hard when TLS_CHACHA20_POLY1305_SHA256 is selected,
regardless of the availability of other ciphers. This means that every
time a connection would have hung, instead it will fail fast, allowing
the client to retry over TLS/TCP.
Theo Buehler recommends that we limit this protection to all LibreSSL
versions before 4.0 since it's where the fix will be implemented. Older
stable versions will just see TLS_CHACHA20_POLY1305_SHA256 disabled,
which should be sufficient to make QUIC work there again as well.
The following config is sufficient to reproduce the issue (on a non-x86
machine, both arm64 & mips64 were confirmed to reproduce it):
global
limited-quic
frontend stats
mode http
#bind :8181
#bind :8443 ssl crt rsa+dh2048.pem
bind quic4@:8443 ssl crt rsa+dh2048.pem alpn h3
timeout client 5s
stats uri /
And the following commands will trigger the problem on affected LibreSSL
versions:
curl --tls13-ciphers TLS_CHACHA20_POLY1305_SHA256 -v --http3 -k https://127.0.0.1:8443/
curl -v --http3 -k https://127.0.0.1:8443/
while these ones must work:
curl --tls13-ciphers TLS_AES_128_GCM_SHA256 -v --http3 -k https://127.0.0.1:8443/
curl --tls13-ciphers TLS_AES_256_GCM_SHA384 -v --http3 -k https://127.0.0.1:8443/
Normally all of them will work with LibreSSL 4, and only the first one
should fail with stable LibreSSL versions higher than 3.9.2. An haproxy
version without this workaround will show an unresponsive command after
the GET is sent, while a version with the workaround will close the
connection on error. On a version with this workaround, if TCP listeners
are uncommented, curl will automatically fall back to TCP and attempt
the reqeust again over HTTP/2. Finally, on OpenSSL 1.1.1 in compat mode
(hence the limited-quic option above) all of them must work.
Many thanks to github user @lgv5 for the detailed report, tests, and
for spotting the issue, and to @botovq (Theo Buehler) for the quick
analysis, patch and help on this workaround.
This needs to be backported to versions 2.6 and above.
Update API for PROXY protocol header encoding. Previously, it requires
stream parameter to be set. Change make_proxy_line() and associated
functions to add an extra session parameter. This is useful in context
where no stream is instantiated. For example, this is the case for rhttp
preconnect.
This change allows to extend PROXY v2 TLV encoding. Replace
build_logline() which requires a stream instance and call directly
sess_build_logline().
Note that stream parameter is kept as it is necessary for unique ID
encoding.
This change has no functional change for standard connections. However,
it is necessary to support TLV encoding on rhttp preconnect.
Modify rhttp preconnect by instantiating a new session for each
connection attempt. Connection is thus linked to a session directly on
its instantiation contrary to previously where no session existed until
listener_accept().
This patch will allow to extend rhttp usage. Most notably, it will be
useful to use various sample fetches on the server line and extend
logging capabilities.
Changes are minimal, yet consequences are considered not trivial as for
the first time a FE connection session is instantiated before
listener_accept(). This requires an extra explicit check in
session_accept_fd() to not overwrite an existing session. Also, flag
SESS_FL_RELEASE_LI is not set immediately as listener counters must note
be decremented if connection and its session are freed before reversal
is completed, or else listener counters will be invalid.
conn_session_free() is used as connection destroy callback to ensure the
session will be freed automatically on connection release.
When a session is allocated for a FE connection, session_free() is
responsible to call listener_release() to decrement listener connection
counters and resume listening.
Until now, <listener> member of session was tested inside session_free()
before invocating listener_release(). To highlight more explicitely the
relation between sessions and listeners, introduce a new flag
SESS_FL_RELEASE_LI. Only session with such flag set will invoke
listener_release() on their cleanup. Flag is set inside
session_accept_fd() on success.
This patch has no functional change. However, it will be useful to
implement session creation for rHTTP preconnect.
Ensure "disable frontend" on a reverse HTTP listener is forbidden by
returing -1 on suspend callback. Suspending such a listener has unknown
effect and so is not properly implemented for now.
This should be backported up to 2.9.
This fixes the fd leak, introduced in the commit d3fc982cd7
("MEDIUM: proto: make common fd checks in sock_create_server_socket").
Initially sock_create_server_socket() was designed to return only created
socket FD or -1. Its callers from upper protocol layers were required to test
the returned errno and were required then to apply different configuration
related checks to obtained positive sock_fd. A lot of this code was duplicated
among protocols implementations.
The new refactored version of sock_create_server_socket() gathers in one place
all duplicated checks, but in order to be complient with upper protocol
layers, it needs the 3rd parameter: 'stream_err', in which it sets the
Stream Error Flag for upper levels, if the obtained sock_fd has passed all
additional checks.
No backport needed since this was introduced in 3.0-dev10.
In commit 55e9e9591 ("MEDIUM: ssl: temporarily load files by detecting
their presence in crt-store"), ssl_sock_load_pem_into_ckch() was
replaced by ssl_sock_load_files_into_ckch() in the crt-store loading.
But the side effect was that we always try to autodetect, and this is
not what we want. This patch reverse this, and add specific code in the
crt-list loading, so we could autodetect in crt-list like it was done
before, but still try to load files when a crt-store filename keyword is
specified.
Example:
These crt-list lines won't autodetect files:
foobar.crt [key foobar.key issuer foobar.issuer ocsp-update on] *.foo.bar
foobar.crt [key foobar.key] *.foo.bar
These crt-list lines will autodect files:
foobar.pem [ocsp-update on] *.foo.bar
foobar.pem
Following David Carlier's work in 98d22f21 ("MEDIUM: shctx: Naming shared
memory context"), let's provide an helper function to set a name hint on
a virtual memory area (ie: anonymous map created using mmap(), or memory
area returned by malloc()).
Naming will only occur if available, and naming errors will be ignored.
The function takes mandatory <type> and <name> parameterss to build the
map name as follow: "type:name". When looking at /proc/<pid>/maps, vma
named using this helper function will show up this way (provided that
the kernel has prtcl support for PR_SET_VMA_ANON_NAME):
example, using mmap + MAP_SHARED|MAP_ANONYMOUS:
7364c4fff000-736508000000 rw-s 00000000 00:01 3540 [anon_shmem:type:name]
Another example, using mmap + MAP_PRIVATE|MAP_ANONYMOUS or using
glibc/malloc() above MMAP_THRESHOLD:
7364c4fff000-736508000000 rw-s 00000000 00:01 3540 [anon:type:name]
Since 40d1c84bf0 ("BUG/MAJOR: ring: free the ring storage not the ring
itself when using maps"), munmap() call for startup_logs's ring and
file-backed rings fails to work (EINVAL) and causes memory leaks during
process cleanup.
munmap() fails because it is called with the ring's usable area pointer
which is an offset from the underlying original memory block allocated
using mmap(). Indeed, ring_area() helper function was misused because
it didn't explicitly mention that the returned address corresponds to
the usable storage's area, not the allocated one.
To fix the issue, we add an explicit ring_allocated_area() helper to
return the allocated area for the ring, just like we already have
ring_allocated_size() for the allocated size, and we properly use both
the allocated size and allocated area to manipulate them using munmap()
and msync().
No backport needed.
crt-store is maint to be stricter than your common crt argument on a
bind line, and is supposed to be a declarative format.
However, since the 'ocsp-update' was migrated from ssl_conf to
ckch_conf, the .issuer file is not autodetected anymore when adding a
ocsp-update keyword in a crt-list file, which breaks retro-compatibility.
This patch is a quick fix that will disappear once we are able to be
strict on a crt-store and autodetect on a crt-list.
The ckch_conf_cmp() function allow to compare multiple ckch_conf
structures in order to check that multiple usage of the same crt in the
configuration uses the same ckch_conf definition.
A crt-list allows to use "crt-store" keywords that defines a ckch_store,
that can lead to inconsistencies when a crt is called multiple time with
different parameters.
This function compare and dump a list of differences in the err variable
to be output as error.
The variant ckch_conf_cmp_empty() compares the ckch_conf structure to an
empty one, which is useful for bind lines, that are not able to have
crt-store keywords.
These functions are used when a crt-store is already inialized and we
need to verify if the parameters are compatible.
ckch_conf_cmp() handles multiple cases:
- When the previous ckch_conf was declared with CKCH_CONF_SET_EMPTY, we
can't define any new keyword in the next initialisation
- When the previous ckch_conf was declared with keywords in a crtlist
(CKCH_CONF_SET_CRTLIST), the next initialisation must have the exact
same keywords.
- When the previous ckch_conf was declared in a "crt-store"
(CKCH_CONF_SET_CRTSTORE), the next initialisaton could use no keyword
at all or the exact same keywords.
This patch adds crt-store keywords from the crt-list on the CLI.
- keywords from crt-store can be used over the CLI when inserting
certificate in a crt-list
- keywords from crt-store are dumped when showing a crt-list content
over the CLI
The ckch_conf_kws.func function pointer needed a new "cli" parameter, in
order to differenciate loading that come from the CLI or from the
startup, as they don't behave the same. For example it must not try to
load a file on the filesystem when loading a crt-list line from the CLI.
dump_crtlist_sslconf() was renamed in dump_crtlist_conf() and takes a
new ckch_conf parameter in order to dump relevant crt-store keywords.
This option allow to disable completely the ocsp-update.
To achieve this, the ocsp-update.mode global keyword don't rely anymore
on SSL_SOCK_OCSP_UPDATE_OFF during parsing to call
ssl_create_ocsp_update_task().
Instead, we will inherit the SSL_SOCK_OCSP_UPDATE_* value from
ocsp-update.mode for each certificate which does not specify its own
mode.
To disable completely the ocsp without editing all crt entries,
ocsp-update.disable is used instead of "ocsp-update.mode" which is now
only used as the default value for crt.
Use the ocsp-update keyword in the crt-store section. This is not used
as an exception in the crtlist code anymore.
This patch introduces the "ocsp_update_mode" variable in the ckch_conf
structure.
The SSL_SOCK_OCSP_UPDATE_* enum was changed to a define to match the
ckch_conf on/off parser so we can have off to -1.
The callback used by ckch_store_load_files() only works with
PARSE_TYPE_STR.
This allows to use a callback which will use a integer type for PARSE_TYPE_INT
and PARSE_TYPE_ONOFF.
This require to change the type of the callback to void * to pass either
a char * or a int depending of the parsing type.
The ssl_sock_load_* functions were encapsuled in ckch_conf_load_*
function just to match the type.
This will allow to handle crt-store keywords that are ONOFF or INT
types.
Remove the "ocsp-update" keyword handling from the crt-list.
The code was made as an exception everywhere so we could activate the
ocsp-update for an individual certificate.
The feature will still exists but will be parsed as a "crt-store"
keyword which will still be usable in a "crt-list". This will appear in
future commits.
This commit also disable the reg-tests for now.
This patch allows the usage of "crt-store" keywords from a "crt-list".
The crtstore_parse_load() function was splitted into 2 functions, so the
keywords parsing is done in ckch_conf_parse().
With this patch, crt are loaded with ckch_store_new_load_files_conf() or
ckch_store_new_load_files_path() depending on weither or not there is a
"crt-store" keyword.
More checks need to be done on "crt" bind keywords to ensure that
keywords are compatible.
This patch does not introduce the feature on the CLI.
