json-c 0.17 defines the ssize_t type using a typedef on Windows.
We have been setting ssize_t for Windows to a different type using
a #define instead of a typedef.
We should have been using a typedef since it is a type.
However, we must also match the exact type they're setting it to or else
the compiler will baulk because the types are different.
Note: in C11, it's fine to use typedef the same type more than once, so
long as you're defining it the same every time.
Add support for compiling with external TomsFastMath library provided by
the system instead of compiling the vendored copy into libclamav.
The vendored source is still built directly into libclamav instead of as
a separate library the way libmspack is done.
The rationale is that:
A) it's more complicated to deal with possibly compiling as static or
dynamic, and also
B) libmspack and libunrar are compiled separately primarily because of
licensing concerns. TomsFastMath public domain, so that isn't a concern.
Resolves: https://bugzilla.clamav.net/show_bug.cgi?id=12562
There are some merits of having the configs in `/etc/clamav` and the databases
in `/var/lib/clamav` to match the way the distros all package it and so these
directories can be mounted volumes if needed.
The DATABASE_DIRECTORY and APP_CONFIG_DIRECTORY variables don't support
absolute paths. This patch changes that.
Also creates a ZIP for non-Admin (per-user) installs.
WIX requires the license file to have a .txt or .rtf extension so I
added the .txt extension. I've taken the opportunity to migrate the 3rd
party licenses to a COPYING subdirectory and have added licensing
details to the README.md file.
To build the installer, install WIX and simply run `cpack -C Release`
Also removed the explicit --config option from the
clamav-clamonacc.service file because it should not be required and
isn't being generated correctly when using autotools anyways, especially
after changes in this commit.
Enabled the metadata collection feature, scan heuristics, and all-match
mode when fuzzing in the interest of better code coverage.
Also remove deprecated STREAM command.
An ENABLE_TESTS CMake option is provided so that users can disable
testing if they don't want it. Instructions for how to use this
included in the INSTALL.cmake.md file.
If you run `ctest`, each testcase will write out a log file to the
<build>/unit_tests directory.
As with Autotools' make check, the test files are from test/.split
and unit_tests/.split files, but for CMake these are generated at
build time instead of at test time.
On Posix systems, sets the LD_LIBRARY_PATH so that ClamAV-compiled
libraries can be loaded when running tests.
On Windows systems, CTest will identify and collect all library
dependencies and assemble a temporarily install under the
build/unit_tests directory so that the libraries can be loaded when
running tests.
The same feature is used on Windows when using CMake to install to
collect all DLL dependencies so that users don't have to install them
manually afterwards.
Each of the CTest tests are run using a custom wrapper around Python's
unittest framework, which is also responsible for finding and inserting
valgrind into the valgrind tests on Posix systems.
Unlike with Autotools, the CMake CTest Valgrind-tests are enabled by
default, if Valgrind can be found. There's no need to set VG=1.
CTest's memcheck module is NOT supported, because we use Python to
orchestrate our tests.
Added a bunch of Windows compatibility changes to the unit tests.
These were primarily changing / to PATHSEP and making adjustments
to use Win32 C headers and ifdef out the POSIX ones which aren't
available on Windows. Also disabled a bunch of tests on Win32
that don't work on Windows, notably the mmap ones and FD-passing
(i.e. FILEDES) ones.
Add JSON_C_HAVE_INTTYPES_H definition to clamav-config.h to eliminate
warnings on Windows where json.h is included after inttypes.h because
json-c's inttypes replacement relies on it.
This is a it of a hack and may be removed if json-c fixes their
inttypes header stuff in the future.
Add preprocessor definitions on Windows to disable MSVC warnings about
CRT secure and nonstandard functions. While there may be a better
solution, this is needed to be able to see other more serious warnings.
Add missing file comment block and copyright statement for clamsubmit.c.
Also change json-c/json.h include filename to json.h in clamsubmit.c.
The directory name is not required.
Changed the hash table data integer type from long, which is poorly
defined, to size_t -- which is capable of storing a pointer. Fixed a
bunch of casts regarding this variable to eliminate warnings.
Fixed two bugs causing utf8 encoding unit tests to fail on Windows:
- The in_size variable should be the number of bytes, not the character
count. This was was causing the SHIFT_JIS (japanese codepage) to UTF8
transcoding test to only transcode half the bytes.
- It turns out that the MultiByteToWideChar() API can't transcode
UTF16-BE to UTF16-LE. The solution is to just iterate over the buffer
and flip the bytes on each uint16_t. This but was causing the UTF16-BE
to UTF8 tests to fail.
I also split up the utf8 transcoding tests into separate tests so I
could see all of the failures instead of just the first one.
Added a flags parameter to the unit test function to open testfiles
because it turns out that on Windows if a file contains the \r\n it will
replace it with just \n if you opened the file as a text file instead of
as binary. However, if we open the CBC files as binary, then a bunch of
bytecode tests fail. So I've changed the tests to open the CBC files in
the bytecode tests as text files and open all other files as binary.
Ported the feature tests from shell scripts to Python using a modified
version of our QA test-framework, which is largely compatible and will
allow us to migrate some QA tests into this repo. I'd like to add GitHub
Actions pipelines in the future so that all public PR's get some testing
before anyone has to manually review them.
The clamd --log option was missing from the help string, though it
definitely works. I've added it in this commit.
It appears that clamd.c was never clang-format'd, so this commit also
reformats clamd.c.
Some of the check_clamd tests expected the path returned by clamd to
match character for character with original path sent to clamd. However,
as we now evaluate real paths before a scan, the path returned by clamd
isn't going to match the relative (and possibly symlink-ridden) path
passed to clamdscan. I fixed this test by changing the test to search
for the basename: <signature> FOUND within the response instead of
matching the exact path.
Autotools: Link check_clamd with libclamav so we can use our utility
functions in check_clamd.c.
Remove the "-rc2" from the version string.
Also bump FLEVEL from 120 -> 121.
Also fixes two issues:
- The VERSION_SUFFIX defined by clamav-config.h.cmake.in must be defined
with #define instead of #cmakedefine, so it is defined as an empty
string even if there is no suffix (eg for an actual release)
- Removed a bashism in the libcheck detection code for autotools,
resolving https://bugzilla.clamav.net/show_bug.cgi?id=12598
This patch adds experimental-quality CMake build tooling.
The libmspack build required a modification to use "" instead of <> for
header #includes. This will hopefully be included in the libmspack
upstream project when adding CMake build tooling to libmspack.
Removed use of libltdl when using CMake.
Flex & Bison are now required to build.
If -DMAINTAINER_MODE, then GPERF is also required, though it currently
doesn't actually do anything. TODO!
I found that the autotools build system was generating the lexer output
but not actually compiling it, instead using previously generated (and
manually renamed) lexer c source. As a consequence, changes to the .l
and .y files weren't making it into the build. To resolve this, I
removed generated flex/bison files and fixed the tooling to use the
freshly generated files. Flex and bison are now required build tools.
On Windows, this adds a dependency on the winflexbison package,
which can be obtained using Chocolatey or may be manually installed.
CMake tooling only has partial support for building with external LLVM
library, and no support for the internal LLVM (to be removed in the
future). I.e. The CMake build currently only supports the bytecode
interpreter.
Many files used include paths relative to the top source directory or
relative to the current project, rather than relative to each build
target. Modern CMake support requires including internal dependency
headers the same way you would external dependency headers (albeit
with "" instead of <>). This meant correcting all header includes to
be relative to the build targets and not relative to the workspace.
For example, ...
```c
include "../libclamav/clamav.h"
include "clamd/clamd_others.h"
```
... becomes:
```c
// libclamav
include "clamav.h"
// clamd
include "clamd_others.h"
```
Fixes header name conflicts by renaming a few of the files.
Converted the "shared" code into a static library, which depends on
libclamav. The ironically named "shared" static library provides
features common to the ClamAV apps which are not required in
libclamav itself and are not intended for use by downstream projects.
This change was required for correct modern CMake practices but was
also required to use the automake "subdir-objects" option.
This eliminates warnings when running autoreconf which, in the next
version of autoconf & automake are likely to break the build.
libclamav used to build in multiple stages where an earlier stage is
a static library containing utils required by the "shared" code.
Linking clamdscan and clamdtop with this libclamav utils static lib
allowed these two apps to function without libclamav. While this is
nice in theory, the practical gains are minimal and it complicates
the build system. As such, the autotools and CMake tooling was
simplified for improved maintainability and this feature was thrown
out. clamdtop and clamdscan now require libclamav to function.
Removed the nopthreads version of the autotools
libclamav_internal_utils static library and added pthread linking to
a couple apps that may have issues building on some platforms without
it, with the intention of removing needless complexity from the
source. Kept the regular version of libclamav_internal_utils.la
though it is no longer used anywhere but in libclamav.
Added an experimental doxygen build option which attempts to build
clamav.h and libfreshclam doxygen html docs.
The CMake build tooling also may build the example program(s), which
isn't a feature in the Autotools build system.
Changed C standard to C90+ due to inline linking issues with socket.h
when linking libfreshclam.so on Linux.
Generate common.rc for win32.
Fix tabs/spaces in shared Makefile.am, and remove vestigial ifndef
from misc.c.
Add CMake files to the automake dist, so users can try the new
CMake tooling w/out having to build from a git clone.
clamonacc changes:
- Renamed FANOTIFY macro to HAVE_SYS_FANOTIFY_H to better match other
similar macros.
- Added a new clamav-clamonacc.service systemd unit file, based on
the work of ChadDevOps & Aaron Brighton.
- Added missing clamonacc man page.
Updates to clamdscan man page, add missing options.
Remove vestigial CL_NOLIBCLAMAV definitions (all apps now use
libclamav).
Rename Windows mspack.dll to libmspack.dll so all ClamAV-built
libraries have the lib-prefix with Visual Studio as with CMake.
New features added to freshclam:
- Update signature definitions over HTTPS.
- Support for HTTP protocol v1.1 (formerly v1.0).
- New libfreshclam library with an all new API and versioning separate from libclamav (v2.0.0). This library is now build and installed alongside libclamav as a hard dependency of freshclam.
- The ability to opt-in and opt-out of standard and optional official ClamAV databases (ExtraDatabase, ExcludeDatabase)
- The option to specify the protocol and port number of official and private mirror servers.
- Support for additional types of proxy servers beyond plain HTTP (SOCKS 4, SOCKS 5).
Features removed from freshclam:
- Mirror management (mirrors.dat) file. This feature is no longer needed as official signature databases are distributed using a paid content delivery network (Cloudflare).
This commit also adds the following features for Windows users:
- The clamsubmit tool.
- The json-c library dependency, which will enable the --gen-json option in clamscan.
- Third party libraries under the win32/3rdparty directory have been removed. Developers will need to build the libraries separately from ClamAV and provide the headers and lib/dll library files the same way they do for OpenSSL. This includes libxml2, pthread-win32, bzip2, zlib, pcre2 as well as new dependencies: curl, json-c. Developers are encouraged to use the build tool Mussels to simplify this task.
To enable prelude compile with ./configure --enable-prelude
In ClamAV configuration file set Prelude Enable on yes and choose an analyzer name with PreludeAnalyzerName (default ClamAV).
You need to have a prelude manager to use this module.
If --block-encrypted is specified then we can detect Encrypted.PDF if:
- PDF is encrypted with R 2,3,4 or 5
- PDF is not displayable without specifying a password
If PDF is encrypted, but is displayable without specifying a password, then it
is not detected as Encrypted.PDF.
Internal version is an LLVM 2.8 with 2 patches backported from LLVM 2.9 to fix a
crash on AVX chips.
So drop support for building with external LLVM 2.8, and add support for
building with external LLVM 2.9 instead.
Caveat:
stack smashing protection is broken on LLVM 2.9 so it is disabled
Example on Debian:
apt-get install llvm-2.9-dev
./configure --enable-llvm --with-system-llvm=/usr/bin/llvm-config-2.9
