When the input length is zero, just return zero early. Otherwise, there's a small chance that memory allocation is engaged, fails and returns -1, which is a bit confusing when nothing should be written.

The warning reads "[cast] may cause misaligned access". Even though this can be application-supplied pointer, misaligned access shouldn't happen, because structure type is "encoded" into data itself, and application would customarily pass correctly aligned pointer.

Without that, output comes one character per line. It's the same issue as has been observed before, this happens when using write() on a record oriented stream (possibly unbuffered too). This also uncovered a bug in BIO_f_linebuffer, where this would cause an error: BIO_write(bio, "1\n", 1); I.e. there's a \n just after the part of the string that we currently ask to get written.

2018-01-31Revert the crypto "global lock" implementationBenjamin Kaduk
Conceptually, this is a squashed version of: Revert "Address feedback" This reverts commit 75551e07bd2339dfea06ef1d31d69929e13a4495. and Revert "Add CRYPTO_thread_glock_new" This reverts commit ed6b2c7938ec6f07b15745d4183afc276e74c6dd. But there were some intervening commits that made neither revert apply cleanly, so instead do it all as one shot. The crypto global locks were an attempt to cope with the awkward POSIX semantics for pthread_atfork(); its documentation (the "RATIONALE" section) indicates that the expected usage is to have the prefork handler lock all "global" locks, and the parent and child handlers release those locks, to ensure that forking happens with a consistent (lock) state. However, the set of functions available in the child process is limited to async-signal-safe functions, and pthread_mutex_unlock() is not on the list of async-signal-safe functions! The only synchronization primitives that are async-signal-safe are the semaphore primitives, which are not really appropriate for general-purpose usage. However, the state consistency problem that the global locks were attempting to solve is not actually a serious problem, particularly for OpenSSL. That is, we can consider four cases of forking application that might use OpenSSL: (1) Single-threaded, does not call into OpenSSL in the child (e.g., the child calls exec() immediately) For this class of process, no locking is needed at all, since there is only ever a single thread of execution and the only reentrancy is due to signal handlers (which are themselves limited to async-signal-safe operation and should not be doing much work at all). (2) Single-threaded, calls into OpenSSL after fork() The application must ensure that it does not fork() with an unexpected lock held (that is, one that would get unlocked in the parent but accidentally remain locked in the child and cause deadlock). Since OpenSSL does not expose any of its internal locks to the application and the application is single-threaded, the OpenSSL internal locks will be unlocked for the fork(), and the state will be consistent. (OpenSSL will need to reseed its PRNG in the child, but that is an orthogonal issue.) If the application makes use of locks from libcrypto, proper handling for those locks is the responsibility of the application, as for any other locking primitive that is available for application programming. (3) Multi-threaded, does not call into OpenSSL after fork() As for (1), the OpenSSL state is only relevant in the parent, so no particular fork()-related handling is needed. The internal locks are relevant, but there is no interaction with the child to consider. (4) Multi-threaded, calls into OpenSSL after fork() This is the case where the pthread_atfork() hooks to ensure that all global locks are in a known state across fork() would come into play, per the above discussion. However, these "calls into OpenSSL after fork()" are still subject to the restriction to async-signal-safe functions. Since OpenSSL uses all sorts of locking and libc functions that are not on the list of safe functions (e.g., malloc()), this case is not currently usable and is unlikely to ever be usable, independently of the locking situation. So, there is no need to go through contortions to attempt to support this case in the one small area of locking interaction with fork(). In light of the above analysis (thanks @davidben and @achernya), go back to the simpler implementation that does not need to distinguish "library-global" locks or to have complicated atfork handling for locks.

2017-08-22This has been added to avoid the situation where some host ctype.h functionsPauli
return true for characters > 127. I.e. they are allowing extended ASCII characters through which then cause problems. E.g. marking superscript '2' as a number then causes the common (ch - '0') conversion to number to fail miserably. Likewise letters with diacritical marks can also cause problems. If a non-ASCII character set is being used (currently only EBCDIC), it is adjusted for. The implementation uses a single table with a bit for each of the defined classes. These functions accept an int argument and fail for values out of range or for characters outside of the ASCII set. They will work for both signed and unsigned character inputs.
