Syscalls
========
-Syscalls made from within an active transaction will not be performed and the
-transaction will be doomed by the kernel with the failure code TM_CAUSE_SYSCALL
-| TM_CAUSE_PERSISTENT.
+Performing syscalls from within transaction is not recommended, and can lead
+to unpredictable results.
-Syscalls made from within a suspended transaction are performed as normal and
-the transaction is not explicitly doomed by the kernel. However, what the
-kernel does to perform the syscall may result in the transaction being doomed
-by the hardware. The syscall is performed in suspended mode so any side
-effects will be persistent, independent of transaction success or failure. No
-guarantees are provided by the kernel about which syscalls will affect
-transaction success.
+Syscalls do not by design abort transactions, but beware: The kernel code will
+not be running in transactional state. The effect of syscalls will always
+remain visible, but depending on the call they may abort your transaction as a
+side-effect, read soon-to-be-aborted transactional data that should not remain
+invisible, etc. If you constantly retry a transaction that constantly aborts
+itself by calling a syscall, you'll have a livelock & make no progress.
-Care must be taken when relying on syscalls to abort during active transactions
-if the calls are made via a library. Libraries may cache values (which may
-give the appearance of success) or perform operations that cause transaction
-failure before entering the kernel (which may produce different failure codes).
-Examples are glibc's getpid() and lazy symbol resolution.
+Simple syscalls (e.g. sigprocmask()) "could" be OK. Even things like write()
+from, say, printf() should be OK as long as the kernel does not access any
+memory that was accessed transactionally.
+
+Consider any syscalls that happen to work as debug-only -- not recommended for
+production use. Best to queue them up till after the transaction is over.
