* Link drti.o with a PIC version of libelf. This is needed becauserpaulo2010-08-211-2/+9
| | | | | | | drti.o depends on libelf and this avoids linking every other drti.o program (namely programs with USDT probes) with libelf. Sponsored by: The FreeBSD Foundation

* Add libdtrace support for tracing userland programs.rpaulo2010-08-2115-218/+712
| | | | | | | | | | | | | | | | | | Summary of changes: * Implement a compatibility shim between Solaris libproc and our libproc and remove several ifdefs because of this. * Port the drti to FreeBSD. * Implement the missing DOODAD sections * Link with libproc and librtld_db * Support for ustack, jstack and uregs (by sson@) * Misc bugfixing When writing the SUWN_dof section, we had to resort to building the ELF file layout by "hand". This is the job of libelf, but our libelf doesn't support this yet. When libelf is fixed, we can remove the code under #ifdef BROKEN_LIBELF. Sponsored by: The FreeBSD Foundation

* Add dedicated routines to toggle lockmgr flags such as LK_NOSHARE andjhb2010-08-2014-19/+47
| | | | | | | | | | | | LK_CANRECURSE after a lock is created. Use them to implement macros that otherwise manipulated the flags directly. Assert that the associated lockmgr lock is exclusively locked by the current thread when manipulating these flags to ensure the flag updates are safe. This last change required some minor shuffling in a few filesystems to exclusively lock a brand new vnode slightly earlier. Reviewed by: kib MFC after: 3 days

* In current implementation, thread cancellation is done in signal handler,davidxu2010-08-206-99/+284
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | which does not know what is the state of interrupted system call, for example, open() system call opened a file and the thread is still cancelled, result is descriptor leak, there are other problems which can cause resource leak or undeterminable side effect when a thread is cancelled. However, this is no longer true in new implementation. In defering mode, a thread is canceled if cancellation request is pending and later the thread enters a cancellation point, otherwise, a later pthread_cancel() just causes SIGCANCEL to be sent to the target thread, and causes target thread to abort system call, userland code in libthr then checks cancellation state, and cancels the thread if needed. For example, the cancellation point open(), the thread may be canceled at start, but later, if it opened a file descriptor, it is not canceled, this avoids file handle leak. Another example is read(), a thread may be canceled at start of the function, but later, if it read some bytes from a socket, the thread is not canceled, the caller then can decide if it should still enable cancelling or disable it and continue reading data until it thinks it has read all bytes of a packet, and keeps a protocol stream in health state, if user ignores partly reading of a packet without disabling cancellation, then second iteration of read loop cause the thread to be cancelled. An exception is that the close() cancellation point always closes a file handle despite whether the thread is cancelled or not. The old mechanism is still kept, for a functions which is not so easily to fix a cancellation problem, the rough mechanism is used. Reviewed by: kib@

Known Issues: * The EHCI USB doesn't currently work and will panic the kernel during attach. * The onboard ethernet won't work until the PLL routines have been fleshed out and shoe-horned into if_arge. * The WMAC device glue (and quite likely the if_ath support) hasn't yet been implemented.
* MFp4: anchie_soc2009 branch:anchie2010-08-1910-14/+612
| | | | | | | | | | | | | | | | | | | | Add kernel side support for Secure Neighbor Discovery (SeND), RFC 3971. The implementation consists of a kernel module that gets packets from the nd6 code, sends them to user space on a dedicated socket and reinjects them back for further processing. Hooks are used from nd6 code paths to divert relevant packets to the send implementation for processing in user space. The hooks are only triggered if the send module is loaded. In case no user space application is connected to the send socket, processing continues normaly as if the module would not be loaded. Unloading the module is not possible at this time due to missing nd6 locking. The native SeND socket is similar to a raw IPv6 socket but with its own, internal pseudo-protocol.
