* Put guard pages next to fast alloc memory
I verified that we can now detect #6753 without creating tons of
threads.
* Use pageSize instead of 4096
* Don't include mmapInternal for windows
* Update 'salt' details for EncryptHeader AuthToken details
Description
Major changes:
1. Add 'salt' to BlobCipherEncryptHeader::cipherHeaderDetails.
2. During decryption it is possible that BlobKeyCacheId doesn't
contain required baseCipherDetails. Add API to KeyCache to
allowing re-populating of CipherDetails with a given 'salt'
3. Update BaseCipherKeyIdCache indexing using {BaseCipherKeyId, salt}
tuple. FDB processes leverage BlobCipherKeyCache to implement
in-memory caching of cipherKeys, given EncryptKeyProxy supplies
BaseCipher details, each encryption participant service would
generate its derived key by using different 'salt'. Further,
it is possible to cache multiple {baseCipherKeyId, salt} tuples;
for instance: CP encrypted mutations being deciphered by
StorageServer etc.
Testing
1. Update EncyrptionOps simulation test to simulate KeyCache miss
2. Update BlobCipher unit tests to validate above mentioned changes
* Don't test requests that don't initialize properly
Some request objects don't initialize their members
properly when being constructed using the default
constructor. This makes valgrind unhappy. Don't test
these endpoints for now.
* fixed code formatting
The ClientDBInfo's comparison is through an internal UID and shrinkProxyList()
can change proxies inside ClientDBInfo. Since the UID is not changed by that
function, subsequent set can be unintentionally skipped.
This was not a big issue before. However, VV introduces a change that the
client side compares the returned proxy ID with its known set of GRV proxies
and will retry GRV if the returned proxy ID is not in the set. Due the above
bug, GRV returned by a proxy is not within the client set, and results in
indefinite retrying GRVs.
There is a bug in how a log router handles streaming read:
* Log router has a `logRouterPeekStream` actor A running.
* Remote tlog detects some problem and starts another streaming connection (maybe just reuse the connection?)
* Log router now has a new `logRouterPeekStream` actor B running.
* B runs and found that popped version > reqBegin, so `LogRouterPeekPopped` . This is because A is still running and changed the popped version.
* A ends with `TLogPeekStreamEnd operation_obsolete`
* B become stuck at `wait(req.reply.onReady() && store(reply.rep, future)`, because the future was sent `Never()`.
As a result, the remote tlog can no longer retrieve data from this log router.
Fix by killing the `logRouterPeekStream` B.
* Re-throw operation_cancelled
There's a few places in fdbcli where we don't rethrow operation
cancelled but wait on a future. It's very unusual that you don't want to
rethrow operation_cancelled.
* Update ASSERT
It's possible to get error_code_broken_promise here if the network has
already shutdown.
