* fixed error in loading cow filesfuse_cowMichael Scherle2018-12-141-1/+1

* bug in read function probably fixed, needs futher testingMichael Scherle2018-12-061-6/+12

* changed standart behavior to not overwrite cow fileMichael Scherle2018-12-024-82/+81Star
| | | | - in standart cow modus, if an cow file exists it will try to load it, if the given cow file doesn't match with the given image it will exit with an error. - added -z parameter to force an cow file overwrite.
* cleaned up code and added improvementsMichael Scherle2018-11-027-481/+391Star
| | | | | | | | - cleaned up code - using fixed size type variables in file - using types.h fixup macros - replaced write/read with pwrite/pread (except for 2 occurrences) - added create fuse callback
* Fixes and also included the Image merging programmMichael Scherle2018-10-155-168/+352

* [KERNEL] Fix keep alive timer on 4.15+Simon Rettberg2018-08-151-1/+1

|
* [SERVER] Use atomic var for (total)bytesSent countersSimon Rettberg2018-08-085-102/+62Star
| | | | | | Gets rid of the lastBytesSent field as well as the stats lock per client. Cleaned and split up the messy net_clientsToJson function while at it.
* [SHARED] Use atomic for logger maskSimon Rettberg2018-08-081-2/+2

* [SERVER] Add missing file mode to open() callSimon Rettberg2018-07-261-2/+2

* [SERVER] Fix compilation on clang (atomic vars)Simon Rettberg2018-07-101-4/+4
|
* [SERVER] Reload server config on SIGHUPSimon Rettberg2018-07-103-70/+96
| | | | | | | Most config settings can now be changed at runtime using SIGHUP. This currently excludes the basePath, listenPort, and the client and image count limits, as well as vmdkLegacyMode.
* [SERVER] Fix use of wrong constant; increase queue len for hash checkerSimon Rettberg2018-07-102-2/+2
|
* [SERVER] Reduce spam some moreSimon Rettberg2018-07-091-1/+1
|
* [SERVER] Introduce backgroundReplication=hashblockSimon Rettberg2018-07-093-38/+142
| | | | | | | | This is a compromise; if you want to validate replicated data fairly quickly, using this option will make background replication only kick in when there's a "dirty" 16M block, i.e. some blocks within a 16M block are cached locally, but not all. Completing the block makes it possible to validate its CRC32 checksum.
* [SERVER] Reduce debug spamSimon Rettberg2018-07-091-2/+1Star
|
* [KERNEL] Add support for kernel 4.17.xSimon Rettberg2018-07-061-0/+11
|
* CMake: Hide kernel option on BSD, make kernel dir configurableSimon Rettberg2018-07-061-6/+7
|
* [FUSE] In panic mode, use a pending range for alt checkSimon Rettberg2018-07-051-5/+43
| | | | | | | | If we lost connection and then go check all known alt servers, see if we have some pending request queued and if so, use its offset and length for the alt server probe. This ensures that the server being tested is able to satisfy at least the next request we'll send.
* [SERVER] Don't keep bg replication blocks in fs cacheSimon Rettberg2018-07-051-1/+5
| | | | | | Further improving cache handling, don't keep blocks in cache that have been requested via background replication. It's likely these aren't needed in the near future.
* [SERVER] Always use fsync instead of fdatasyncSimon Rettberg2018-07-052-9/+2Star
| | | | | | | | Now that we support sparse files, using just fdatasync isn't safe anymore. Instead of handling both cases differently just drop fdatasync, the difference has probably been marginal all along anyways.
* [SERVER] Use O_DIRECT for integrity checksSimon Rettberg2018-07-042-30/+67
| | | | | | | | | | | | | | The idea is that for full image checks, we don't want to pollute the fs cache with gigabytes of data that won't be needed again soon. This would certainly hurt performance on servers that dont have hundreds of GBs of RAM. For single block checks during replication this has the advantage that we don't check the block in memory before it hit the disk once, but actually flush the data to disk, then remove it from the page cache, and only then read it again, from disk. TODO: Might be worth making this a config option
* [SERVER] Refactor uplink/cache handling, improve crc checkingSimon Rettberg2018-07-049-290/+351
| | | | | | | | | | | | | The cacheFd is now moved to the uplink data structure and will only be handled by the uplink thread. The integrity checker now supports checking all blocks of an image. This will be triggered automatically whenever a check for a single block failed. Also, if a crc check on startup fails, the image won't be discarded anymore, but rather a full check will be initiated. Furthermore, when calling image_updateCacheMap() on an image that was previously complete, the cache map will now be re-initialized, and a new uplink connection created.
* [SERVER] cmake: Add config option for extra compiler opptionsSimon Rettberg2018-07-041-5/+6
|
* [SERVER] Use likely/unlikely in uplink disk writing loopSimon Rettberg2018-06-252-4/+12
|
* [SERVER] Try to re-open cacheFd if writing failsSimon Rettberg2018-06-253-7/+58
| | | | | | | In scenarios where the proxy is using an NFS server as storage (for whatever crazy reason) or when the cacheFd goes bad through e.g. a switchroot, try to re-open it instead of just disabling caching forever.
* [SERVER] Make sure image has read fd before readingSimon Rettberg2018-06-133-29/+60
|
* [FUSE] Return 0 instead of EIO if trying to read past endSimon Rettberg2018-06-131-1/+1
| | | | | read() calls are supposed to return 0 when reading at EOF, so properly mimic that behavior.
* [FUSE] Move variables into block where they're being usedSimon Rettberg2018-06-131-4/+4

|
* [SERVER] Fix deadlock on shutdown (via image_tryFreeAll)Simon Rettberg2018-04-241-4/+8
| | | | | imageListLock was locked on twice in the call stack, which is bad if you're using non-recursive locks.

|
* [SERVER] Add bgrMinClients: Thresold to control when BGR startsSimon Rettberg2018-04-124-5/+18
