* [KERNEL]: change probing logic to select first available serverManuel Bentele2020-11-092-16/+25
| | | | | | | This patch changes the probing logic to select the first available dnbd3-server submitted by the ioctl OPEN call. All other specified dnbd3-servers are added to the alternative server list and do not have to be available.
* [KERNEL, CLIENT]: submit and probe multiple dnbd3-server with ioctl OPENManuel Bentele2020-11-064-104/+263
| | | | | | | | | | The ioctl OPEN call for DNBD3 devices exposed by the dnbd3 Linux kernel module, is extended with a fixed array of dnbd3 hosts. The fixed array allows the dnbd3-client to submit host information (IP address and port) of multiple dnbd3-servers. This information is used to probe all submitted dnbd3-servers and add them to the alternative dnbd3-server list. If at least one dnbd3-server is not reachable, the OPEN ioctl call will abort with an error code.

* [SERVER] Update nextSave timestamp at start of functionSimon Rettberg2020-10-291-4/+6
| | | | | | | | | saveLoadAllCacheMaps() is called frequently, and a 'full' run can take some time. If we only update the nextSave timestamp when we're done, we might already have a concurrent call to the function, which will also do a 'full' run, since the timestamp is not updated yet. This doesn't break anything, but leads to even more disk activity, which is probably already high, given that the previous run is not done yet.
* [BUILD] remove the build requirement for an unused C++ compilerManuel Bentele2020-10-277-7/+14
| | | | | This patch sets the programming languages of each CMake project to C. With this change, CMake does not search for an unused C++ compiler anymore.
* [BUILD] fix comments and remove useless code fragments in CMake filesManuel Bentele2020-10-231-6/+5Star

* [BUILD] disable build of dnbd3-client if Linux kernel module is disabledManuel Bentele2020-10-221-2/+2

* [BUILD] add CMake targets to build binary and source packages with CPackManuel Bentele2020-10-2211-18/+24
| | | | | | | | | | | This patch adds the following CMake targets - package - source to build bundeled packages. Those packages contain either all built binary artifacts or all source files for source code distribution. Both CMake targets are available in Release build configuration.
* [BUILD] add option to build the dnbd3-server with afl-fuzz supportManuel Bentele2020-10-205-16/+55
| | | | | The afl-fuzz support for the dnbd3-server requires an AFL C compiler like afl-gcc and can be enabled with the CMake option DNBD3_SERVER_AFL.
* [BUILD] set build type and stop Release build if repository is dirtyManuel Bentele2020-10-197-17/+14Star

* [BUILD] fixes issues to build user space programs on FreeBSD 12.1Manuel Bentele2020-10-197-5/+7

* [BUILD] rewrite CMake build system to track changes of source filesManuel Bentele2020-10-1664-1102/+306Star
| | | | | | | | | | This change restructures the source code directories, separates shared form non-shared application code and adds CMake dependencies. These dependencies allow the tracking of changes and trigger a rebuild of those build targets where changed files are involved. WARNING: Note that the support of the DNBD3_SERVER_AFL build option is not supported yet. Thus, the option should be never turned on.
* [KERNEL] ported socket time structures to support CentOS 8 kernel 4.18Manuel Bentele2020-10-131-1/+24
| | | | | | | | | This patch implements the old time structures to support Linux kernels prior to version 5.1.x. WARNING: This change to the deprecated time structures does not solve the Y2038 issue. Thus, the dnbd3 Linux kernel module can only run under Linux kernels prior to version 5.1.x until the end of year 2037.
* [KERNEL] set socket timeouts with new function and time structureManuel Bentele2020-08-311-8/+30
| | | | | | | | | | This patch replaces the deprecated kernel_setsockopt() function with the socket generic function sock_setsockopt() to set the send and receive timeout for all used sockets in the kernel module. The timeout data type is choosen according to the available kernel version, so that the dnbd3 kernel module supports the new y2038-problem-solving socket options. With both changes, the kernel module runs on Linux kernel 5.4 LTS and later (including Linux kernel 5.9).
* [KERNEL] make private network functions staticManuel Bentele2020-08-282-294/+286Star

* [KERNEL] convert debug messages and clean up codeManuel Bentele2020-08-287-203/+254
| | | | | | | | | | | | This change converts all debug messages to support the Linux kernel's dynamic debug feature. Debug messages can be enabled or disabled by the debug feature if the - kernel module is built in debug mode (EXTRA_CFLAGS=-g -DDEBUG) - Linux kernel supports dynamic debug (CONFIG_DYNAMIC_DEBUG is set) This patch removes outdated kernel compatibility macros (used for Linux kernels in version 4.x) and cleans up the kernel module's code.
* [KERNEL] convert to blk-mq and ktimeManuel Bentele2020-08-274-144/+177
| | | | | | | | | | | This converts the dnbd3 kernel module driver to use the blk-mq infrastructure, which allows the dnbd3 kernel module driver to be compatible with Linux kernels in version 5.x or later. The conversion of the implementation uses one hardware queue to preserve the existing send/receive and load-balancing logic, but can be scaled up in the future. In addition to that, time measurements in the implementation are converted to ktime based accessors to replace the use of deprecated time interfaces.
* [SERVER] Fix rid 0 proxy lookup if local version is newerSimon Rettberg2020-08-141-5/+15

| | | | | | | | | | | | | | This is about 16x as fast as before with the lookup table for processing 4 bytes at a time and should work on any AMD64 CPU made in the last decade. We still need an AltiVec implementation for G5 though.
