e5ff14100a CLEANUP: Compare the return value of XXXcmp() functions with zero
According to coding-style.txt it is recommended to use:

`strcmp(a, b) == 0` instead of `!strcmp(a, b)`

So let's do this.

The change was performed by running the following (very long) coccinelle patch
on src/:

b7fdfdfd92 MEDIUM: ssl: fatal error with bundle + openssl < 1.1.1
Since HAProxy 2.3, OpenSSL 1.1.1 is a requirement for using a
multi-certificate bundle in the configuration. This patch emits a fatal
error when HAProxy tries to load a bundle with an older version of
HAProxy.

This problem was encountered by an user in issue #990.

This must be backported in 2.3.

77e1c6fb0a BUG/MEDIUM: ssl/crt-list: fix error when no file found
When a file from a crt-list was not found, this one was ignored silently
letting HAProxy starts without it.

This bug was introduced by 47da821 ("MEDIUM: ssl: emulates the
multi-cert bundles in the crtlist").

This commit adds a found variable which is checked once we tried every
bundle combination so we can exits with an error if none were found.

86c2dd60f1 BUG/MEDIUM: ssl/crt-list: bundle support broken in crt-list
In issue #970 it was reported that the bundle loading does not work
anymore with crt-list.

multi-cert bundles in the crtlist") which incorrectly uses "path"
instead of "crt_path" in the name resolution.

50c03aac04 BUG/MEDIUM: ssl/crt-list: correctly insert crt-list line if crt already loaded
In issue #940, it was reported that the crt-list does not work correctly
anymore. Indeed when inserting a crt-list line which use a certificate
previously seen in the crt-list, this one won't be inserted in the SNI
list and will be silently ignored.

This bug was introduced by commit  47da821 "MEDIUM: ssl: emulates the
multi-cert bundles in the crtlist".

This patch also includes a reg-test which tests this issue.

This bugfix must be backported in 2.3.

b9f6accc9e MINOR: ssl: Add error if a crt-list might be truncated
Similar to warning during the parsing of the regular configuration file
that was added in 2fd5bdb439 this patch adds
a warning to the parsing of a crt-list if the file does not end in a
newline (and thus might have been truncated).

The logic essentially just was copied over. It might be good to refactor
this in the future, allowing easy re-use within all line-based config
parsers.

see https://github.com/haproxy/haproxy/issues/860#issuecomment-693422936
see 0354b658f0

This should be backported as a warning to 2.2.

bd8e6eda59 CLEANUP: ssl: remove test on "multi" variable in ckch functions
Since the removal of the multi-certificates bundle support, this
variable is not useful anymore, we can remove all tests for this
variable and suppose that every ckch contains a single certificate.

47da82111d MEDIUM: ssl: emulates the multi-cert bundles in the crtlist
The multi-certificates bundle was the common way of offering multiple
certificates of different types (ecdsa and rsa) for a same SSL_CTX.
This was implemented with OpenSSL 1.0.2 before the client_hello callback
was available.

Now that all versions which does not support this callback are
depracated (< 1.1.0), we can safely removes the support for the bundle
which was inconvenient and complexify too much the code.

This patch emulates the bundle loading by looking for the bundle files
when the specified file in the configuration does not exist. It then
creates new entries in the crtlist, so they will appear as new line if
they are dumped from the CLI.

same SNI host. Remove this support temporarely so it is replaced by
the loading of each certificate in a separate SSL_CTX.

0354b658f0 BUG/MINOR: ssl/crt-list: crt-list could end without a \n
Since the refactoring of the crt-list, the same function is used to
parse a crt-list file and a crt-list line on the CLI.

The assumption that a line on the CLI and a line in a file is finished
by a \n was made. However that is potentialy not the case with a file
which does not finish by a \n.

9ab8f8d1b6 BUG/MINOR: ssl/cli: certs added from the CLI can't be deleted
In ticket #706 it was reported that a certificate which was added from
the CLI can't be removed with 'del ssl cert' and is marked as 'Used'.

The problem is that the certificate instances are not added to the
created crtlist_entry, so they can't be deleted upon a 'del ssl
crt-list', and the store can't never be marked 'Unused' because of this.

This patch fixes the issue by adding the instances to the crtlist_entry,
which is enough to fix the issue.

aeed4a85d6 REORG: include: move log.h to haproxy/log{,-t}.h
The current state of the logging is a real mess. The main problem is
that almost all files include log.h just in order to have access to
the alert/warning functions like ha_alert() etc, and don't care about
logs. But log.h also deals with real logging as well as log-format and
depends on stream.h and various other things. As such it forces a few
heavy files like stream.h to be loaded early and to hide missing
dependencies depending where it's loaded. Among the missing ones is
syslog.h which was often automatically included resulting in no less
than 3 users missing it.

Among 76 users, only 5 could be removed, and probably 70 don't need the
full set of dependencies.

A good approach would consist in splitting that file in 3 parts:
  - one for error output ("errors" ?).
  - one for log_format processing
  - and one for actual logging.

48fbcae07c REORG: tools: split common/standard.h into haproxy/tools{,-t}.h
And also rename standard.c to tools.c. The original split between
tools.h and standard.h dates from version 1.3-dev and was mostly an
accident. This patch moves the files back to what they were expected
to be, and takes care of not changing anything else. However this
time tools.h was split between functions and types, because it contains
a small number of commonly used macros and structures (e.g. name_desc)
which in turn cause the massive list of includes of tools.h to conflict
with the callers.

They remain the ugliest files of the whole project and definitely need
to be cleaned and split apart. A few types are defined there only for
functions provided there, and some parts are even OS-specific and should
move somewhere else, such as the symbol resolution code.

8d2b777fe3 REORG: ebtree: move the include files from ebtree to include/import/
This is where other imported components are located. All files which
used to directly include ebtree were touched to update their include
path so that "import/" is now prefixed before the ebtree-related files.

The ebtree.h file was slightly adjusted to read compiler.h from the
common/ subdirectory (this is the only change).

A build issue was encountered when eb32sctree.h is loaded before
eb32tree.h because only the former checks for the latter before
defining type u32. This was addressed by adding the reverse ifdef
in eb32tree.h.

No further cleanup was done yet in order to keep changes minimal.

In the CLI command 'show ssl crt-list', the ssl-min-ver and the

To fix the problem, this patch separates the variables to have one with
the configured version, and one with the actual version used. The dump
only shows the configured version.
