2016-01-26ssl: Only start a new session validator if the old one has finished its workIngela Anderton Andin
If the session table is big the validator may not have finshed before the validation interval is up, in this case we should not start a new validator adding to the cpu load.
2015-12-03ssl: Add upper limit for session cacheIngela Anderton Andin
If upper limit is reached invalidate the current cache entries, e.i the session lifetime is the max time a session will be keept, but it may be invalidated earlier if the max limit for the table is reached. This will keep the ssl manager process well behaved, not exhusting memeory. Invalidating the entries will incrementally empty the cache to make room for fresh sessions entries.

2015-02-09ssl: erlang:timestamp -> os:timestampIngela Anderton Andin
For comparison with file time stamps os:timestamp makes more sense and is present in 17 as well as 18.

2015-02-06ssl: Improve PEM cache by validating entriesIngela Anderton Andin
The PEM cache is now validated by a background process, instead of always keeping it if it is small enough and clearing it otherwhiss. That strategy required that small caches where cleared by API function if a file changes on disk. However document the clearing API function as it can still be usefull.
2014-10-13ssl: Separate session cache for client and serverIngela Anderton Andin
Even though in the most common case an erlang node will not be both client and server, it may happen (for instance when running the erlang ditribution over TLS). Also try to mitigate the affect of dumb clients that could cause a very lagre session cache on the client side that can cause long delays in the client. The server will have other means to handle a large session table and will not do any select operations on it anyhow.
2014-06-16Revert "ssl: Avoid creating a huge session table"Ingela Anderton Andin

2014-02-14Fix edoc usage errorsPierre Fenoll
Errors discovered using `erldocs`: Superfluous @hidden tag would exit edoc application; 'Multiple @spec tag': appended a @clear tag after macro condition; '@spec arity does not match': added missing argument.
2013-08-28ssl: Make the ssl manager name for erlang distribution over SSL/TLSIngela Anderton Andin
relative to the module name of the ssl_manager. This can be beneficial when making tools that rename modules for internal processing in the tool.

2013-01-17ssl: Certificates and PEM-cache cleaning fixed to avoid memory leakIngela Anderton Andin
Certificate db cleaning messages where sent to the wrong process after restructuring to avoid bottlenecks. It is possible that the ssl manager process gets two cleaning messages for the same entry. E.i. first cleaning message is sent and before it is processed a new reference is allocated and again released for the entry, generating a second cleaning message. Also in ssl_manger:handle_info/2 it is possible that there exists a new reference to an "old" file name with a potential new content.

2012-06-19ssl: Fix pem cache bugIngela Anderton Andin
A general case clause was put before a less general so that the less general case would never match.
2012-06-08ssl: File handling optimizationIngela Anderton Andin
Avoid cach validation with file:file_info/2 as this i too expensive and causes a bottleneck in the file server. Instead we expose a new API function ssl:clear_pem_cache/0 to deal with the problem. As we think it will be of occasional use and the normal case is that the cache will be valid we think it is the right thing to do. Convert file paths to binary representation in the ssl API module to avoid uncessarry calls in file later on. Also add sanity checks for openssl versions in testsuite due to new openssl bugs.
2012-06-08ssl: Simpler PEM cacheIngela Anderton Andin
2012-06-08ssl: Move ets:select bottleneck in serverDan Gudmundsson
Only use ssl_manager for selecting new ids to guarantee uniqueness, but reuse check does not need to be performed by the manager.
2012-06-08ssl: Move and avoid ets:select bottleneck in clientIngela Anderton Andin
Do not use ssl_manager process for selecting an id. It's unnecessary to involve the manager process at all on the client side.
2011-12-06Improve ssl session cleanup testIngela Anderton Andin
Check last delay timer for both client and server side to avoide timing issues.
2011-11-16Merge branch 'ia/ssl/ets-next-problem/OTP-9703'Ingela Anderton Andin
* ia/ssl/ets-next-problem/OTP-9703: Replaced ets:next traversal with ets:foldl and throw
2011-11-15Replaced ets:next traversal with ets:foldl and throwIngela Anderton Andin
ets:next needs an explicit safe_fixtable call to be safe, we rather use ets:foldl and throw to get out of it when we find the correct entry.
2011-11-15Improved session cleanup handlingIngela Anderton Andin
Added session status "new" to mark sessions that are in the session database to reserve the session id but not resumable yet and that we want to separate from sessions that has been invalidated for further reuse.

2011-08-31Use inet and gen_* dialyzer specsIngela Anderton Andin
2011-06-29Removed global name from the certificate tabelIngela Anderton Andin
We want the certificate table to be handled the same way as the session table and not have a global name, so that we may easier create a separate ssl-manager to handle erlang distribution over ssl.
2011-06-27Use erlang:send_after instead of timer:send_afterIngela Anderton Andin
Also save latest delay cleanup timer ref so that we can use erlang:read_timer to write a more reliable test case.
2011-06-01The clean up of the session table now works as intended.Ingela Anderton Andin
In ssl-4.1.5 temporary clean-up processes would crash resulting in that the session table would not be cleaned up (e.i. using more and more memory) and error reports would be printed, but connections would not be affected.
2011-05-24Corrected last argument to timer:apply_after also corrected a dilyzer specIngela Anderton Andin
2011-05-13Ssl sometimes fails when reusing a sessionIngela Anderton Andin
Invalidation of a session for reusing should first flag that the session may no longer be reused and then later when all possible pending reuses have been handled delete the session from the database. This could otherwise cause the client to terminate due to {badarg,[{erlang,byte_size,[undefined]}, and the server to terminate due to {{badmatch,{resumed,undefined}}.
2010-12-16Cache invalidation and consistent user closingIngela Anderton Andin
Added cache invalidation control of ssl certificates so that sessions will not be reused if file content is changed. There was a glitch in ssl:close that made it possible to to get eaddrinuse even though reuseadder-option was used. Also improved tests for better user-close handling.
