Currently the systemd service unit files are installed
into /lib/systemd/system if that directory exists. This
might not be optimal for every user, e.g. when the build
system is not the target system or when building as an
unprivileged user using CMAKE_INSTALL_PREFIX.
Make this configurable by adding a cached cmake variable
CMAKE_INSTALL_SYSTEMD_UNITDIR. Usage:
- install unit files into /lib/systemd/system if it exists (old
behavior)
cmake
- don't install unit files
cmake -D CMAKE_INSTALL_SYSTEMD_UNITDIR=
- install into absolute path
cmake -D CMAKE_INSTALL_SYSTEMD_UNITDIR=/path
- install into path relative to ${CMAKE_INSTALL_PREFIX}
cmake -D CMAKE_INSTALL_SYSTEMD_UNITDIR=path
The function has been greatly improved, here are some of the changes:
- The required SESSION (c->Session) parameter is checked correctly: the function returns immediately in case it's NULL. Previously, the function didn't return in case the parameter was NULL; multiple checks were in place, but not in all instances where the parameter was dereferenced.
- The resolved IP address is cached with all proxy types.
- The "RestoreServerNameAndPort" variable is documented.
- The Debug() messages have been improved.
This commit moves the generic (not related to our protocol) proxy stuff from Cedar to Mayaqua, in dedicated files.
The functions are refactored so that they all have the same arguments and follow the same logic.
Dedicated error codes are added, in order to indicate clearly why the function(s) failed.
Coverity Scan detected an out-of-bounds access issue: OvsProcessData() checked whether the payload size was bigger than the size of the buffer, instead of checking whether the entire packet size (payload size + 2 bytes) was, resulting in an out-of-bounds access in case the payload size is bigger than 1998.
This commit also improves the variable names, the comments and adds two Debug() lines.
OvsDecrypt() returns 0 when it fails, resulting in "size" rolling over with an end result of 4294967292.
This commit fixes the issue by checking whether "size" is greater than sizeof(UINT) before performing the subtraction.
The bug was caused by a typo in the StrCpy() call: the source buffer was the same as the destination one, meaning that the function didn't do anything.
- Fixed the RADIUS PEAP client to use the standard TLS versioning.
- Implementation of a function to fix the MAC address of L3 VPN protocol by entering e.g. "MAC: 112233445566" in the "Notes" field of the user information.
- Implementation of a function to fix the virtual MAC address to be assigned to the L3 VPN client as a string attribute from RADIUS server when authentication.
Hardcoded paths are used in log file enumeration such as LogFileList
command or GenerateEraseFileList function to delete old log files when
disk free space is lacking.
Fixes: SoftEtherVPN/SoftEtherVPN#972
If SecureNAT is enabled and the hostname of the server
is longer than 16characters, every NETBIOS name resolution
query triggers the buffer overflow. If the server was built
with stack protection, the process will be killed.
This commit adds a protocol interface to the server, its purpose is to manage TCP connections and the various third-party protocols.
More specifically, ProtoHandleConnection() takes care of exchanging the packets between the local and remote endpoint; the protocol implementation only has to parse them and act accordingly.
The interface knows which protocol is the connection for by calling IsPacketForMe(), a function implemented for each protocol.
My previous patch used a wrong if directive, which disabled removed
(de)initialization and threading for LibreSSL. This most likely causes
issues at runtime.
A race condition in the DHCP server caused it to offer the same IP address to multiple clients when they connected at the same time, because an offered IP address was considered free until the final step (DHCP_ACK).
This commit introduces a list to keep track of the pending leases created during DHCP_OFFER, so that an IP address is guaranteed to be offered to a single client.
StrCat() appends a string to an already existing string. In order to know where the existing string ends, it uses StrLen() which in turn uses strlen(), a function considered unsafe because it doesn't stop until it finds the null character.
Since the string was allocated but not initialized, StrCat() was either:
- Working correctly.
- Copying only a part of the string.
- Making the program crash via strlen().
The fix consists in using StrCpy(), which starts writing at the beginning of the string.
SSL_free() also frees the associated context.
d6c3c1896c/ssl/ssl_lib.c (L1209)
From https://www.openssl.org/docs/man1.1.1/man3/SSL_free.html:
"SSL_free() also calls the free()ing procedures for indirectly affected items, if applicable: the buffering BIO, the read and write BIOs, cipher lists specially created for this ssl, the SSL_SESSION. Do not explicitly free these indirectly freed up items before or after calling SSL_free(), as trying to free things twice may lead to program failure."

This allows an OpenVPN client to bypass a firewall which is aware of the protocol and is able to block it.
The XOR mask set on the server has to be the same on the client, otherwise it will not be able to connect with certain obfuscation modes.
A special OpenVPN client built with the "XOR patch" is required in order to use this function, because it has never been merged in the official OpenVPN repository.
Two parameters are added to the server configuration: "OpenVPNObfuscationMethod" and "OpenVPNObfuscationMask".
Their value can be retrieved with "OpenVpnObfuscationGet" and set with "OpenVpnObfuscationEnable" in the VPN Command Line Management Utility.

1. ifdef DEBUG -> defined(_DEBUG) || defined(DEBUG)
In VC++ compilers, the macro is "_DEBUG", not "DEBUG".
2. If set memcheck = true, the program will be vitally slow since it will log all malloc() / realloc() / free() calls to find the cause of memory leak.
For normal debug we set memcheck = false.
Please set memcheck = true if you want to test the cause of memory leaks.
This commit improves the RecvFrom() and RecvFrom6() functions by:
- Using the right data type for the struct size variable passed to recvfrom().
- Improving the arguments validation mechanism.
- Printing unhandled errors.
- Hash() has been removed because it was ambiguous, Md5() and Sha0() are proper replacements.
- HMacMd5() and HMacSha1() now share a common implementation handled by the new Internal_HMac() function.
- NewMd() and MdProcess() now support plain hashing (without the key).
- NewMd(), SetMdKey() and MdProcess() now check the OpenSSL functions' return value and in case of failure a debug message is printed along with the error string, if available.
- SetMdKey()'s return value has been changed from void to bool, so that it's possible to know whether the function succeeded or not.
- MdProcess()' return value has been changed from void to UINT (unsigned int) and the function now returns the number of bytes written by HMAC_Final() or EVP_DigestFinal_ex().

The workaround was required for the "net30" topology because:
"There is a problem in your selection of --ifconfig endpoints [local=192.168.30.10, remote=192.168.30.1]. The local and remote VPN endpoints must exist within the same 255.255.255.252 subnet. This is a limitation of --dev tun when used with the TAP-WIN32 driver. Try 'openvpn --show-valid-subnets' option for more info."

OpenVPN sends the cipher name in uppercase, even if it's not standard, thus we have to convert it to lowercase for EVP_get_cipherbyname().
We also have to send the cipher name as it was received from the OpenVPN client, unless it's a different cipher, to prevent a message such as:
"WARNING: 'cipher' is used inconsistently, local='cipher AES-128-GCM', remote='cipher aes-128-gcm'"
It happens because OpenVPN uses "strcmp()" to compare the local and remote parameters: a6fd48ba36/src/openvpn/options.c (L3819-L3831)
See https://github.com/openssl/openssl/issues/6921 for EVP_get_cipherbyname().

With server certificate validation enabled, vpnclient unconditionally
stopped connection on untrusted server certificate. Added account
configuration parameter to retry connection if server certivicate failed
validation.
On startup client creates TUN interface in UP state and kept it UP even
if connection to the server was lost. Creating interface in DOWN state,
turning it UP on successful (re-)connection to server and DOWN on either
disconnect or connection loss would enable DHCP client (say dhclient5)
to detect necessity for lease renewal.
Added a client configuration parameter to create TUN interface in DOWN
state and commands to enable, disable, and query the configuration
parameter.
Enabling the parameter causes client to put all unused TUN interfaces
DOWN, create new TUN interfaces in DOWN state, and turn TUN interfaces
corresponding to active sessions DOWN on connection loss or
disconnecting from server.
Disabling the parameter forces client to turn all TUN interfaces UP and
create new TUN interfaces in UP state.
Default value is 'Disable'.

zlib doesn't have a dedicated directory on Unix systems, because it has a single header, meaning that the header from the repository was being used instead.
This commit moves the header to the Windows includes directory, so that we can use the proper include path on all systems.
Hubname has to be set after copy or it will be an empty string. To get the real hubname (correct casing) we use it directly from the hub instead of the given parameter
Before, it would end up far in the future. Now it gets clamped
to 1970. This should be fine since dates before 1970 are not
actively used. If they are, then the UINT64 should be replaced
by the time64t in quite a few places.

This commit also fixes the problem described in #31, which was caused by the test key generated in RsaCheck() being too small for newer OpenSSL versions.
This allows a DHCP server to use the client ID as unique identifier, in order to correctly assign a static lease.
Previously this wasn't possible, as the client identifier was set to its MAC address, which is randomly generated.
OpenVPN sends the default gateway's MAC address, if the option --push-peer-info is enabled.
It also sends the client's environment variables whose names start with "UV_".
This commit adds some lines of code in OvsBeginIPCAsyncConnectionIfEmpty(), in order to set the hostname to "UV_HOSTNAME"'s value, which is defined by the user on their device.
In case "UV_HOSTNAME" is not available, "IV_HWADDR"'s value (the default gateway's MAC address) is used instead.
OvsParseOptions() has been adapted into a new function called OvsParsePeerInfo(), in order to parse the peer info string.

When loading the DLL file by the LoadLibrary() function in Windows VPN programs, we changed the behavior not to search the current directory. Based on this improvement, even if there are untrusted DLL files in the calendar directory, it is now safe to avoid the problem of unexpected security problem caused by the default loading behavior of Windows. Acknowledgments: This is based on a report by Herman Groeneveld, aka Sh4d0wman.
Fixed an issue that the VPN Client Virtual Network Driver fails to communicate when LTE or 3G wireless modems are used to connect to the internet by the computer running Windows 10 Spring Creators Update (version 1803). Please be careful that It is necessary to reinstall the device driver of the Virtual Network Adapter after upgrading the VPN client to build 9666 or later in order to solve the problem.
When installing a new device driver of the Virtual Network Driver card, we changed the initial random MAC address from 00-AC-xx-xx-xx-xx to 5E-xx-xx-xx-xx-xx. This realizes the compliance with the local address bit of the MAC address rule.
Fixed an issue that the VPN Client Virtual Network Driver fails to communicate when LTE or 3G wireless modems are used to connect to the internet by the computer running Windows 10 Spring Creators Update (version 1803). Please be careful that It is necessary to reinstall the device driver of the Virtual Network Adapter after upgrading the VPN client to build 9666 or later in order to solve the problem.
state of global mutex which may be in intermidiate taken status by one of
threads of the parent, then in child process it tries to get this mutex
and is always pending. One example of mutex is malloc_lock, and there are more.

* Allow specifying cipher suites instead of single ciphers.
CipherName now specifies all cipher suites instead of the
preferred cipher. This allows insecure ciphers like RC4 to
be permanently disabled, instead of being the default fallback
when the preferred cipher is unsupported.
CipherName is now left for OpenSSL to verify. Should it be
invalid, a secure default is used. The default CipherName setting
for new servers is one such invalid string: "~DEFAULT~". This
allows for future updates to change the default and the servers
can stay secure.
* Remove unused temporary variable.
Buffer overread in ParseL2TPPacket()
Memory corruption in IcmpParseResult
Missing bounds check in ParseUDP() can lead to invalid memory access
Out-of-bounds read in IPsec_PPP.c (unterminated string buffer)
Overlapping parameters to memcpy() via StrToIp6()
PACK ReadValue() crash vulnerability
Potential use of uninitialized memory via IPToInAddr6()
4 memory leaks. While the amount of leakage is very small per time, these bugs can finally cause process crash by out of memory. So these bugs must be fixed.
Memory leak in NnReadDnsRecord
Memory leak in RadiusLogin()
Memory leak via ParsePacketIPv4WithDummyMacHeader
Remote memory leak in OpenVPN server code
1 coding improvement. This is not a bug, however, I fixed the code to avoid furture misunderstanding.
RecvAll can return success on failure (leading to use of uninitialized memory)

BUILD_WINDOWS.TXT, BUILD_UNIX.TXT removed from root folder
src/BUILD_WINDOWS.TXT, src/BUILD_UNIX.TXT converted to "md"
BUILD_WINDOWS.TXT, BUILD_UNIX.TXT are now hyperlinks in README.md
Using the global client variable might lead to strange behavoir if multiple clients are allocated and to crashes in the case the client was not initialized with CtStartClient()
Suppose there is a TCP SYN or SYN-ACK packet taking options as:
02 04 05 b4 01 01 04 02 01 03 03 04
which is
Options: (12 bytes)
>Maximum segment size: 1460 bytes
>No-Operation (NOP)
>No-Operation (NOP)
>TCP SACK Permitted Option: True
>No-Operation (NOP)
>Window scale: 4 (multiply by 16)
Then the original parse function only returns MSS 1460 while WSS is 0.

Due to DROWN (CVE-2016-0800), SSLv2 must be disabled by default. This is the most straight-forward way to ensure new installations are not vulnerable. The upgrade use case is not addressed by this PR, though I posted information to the forum: http://www.vpnusers.com/viewtopic.php?f=7&t=5596
This patch is made available under Contribution Option 1, to allow PacketiX to be fixed the same way.
