Further, sys/arm/arm/elf_trampoline.c is an example of file which uses armv4 like pmap implementation for both armv4 and armv6 platforms.

* fputs: Return the number of bytes written.Pedro F. Giffuni2016-02-151-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | POSIX.1-2008 requires that successful completion simply return a non-negative integer. We have regularly returned a constant value. Another, equally valid, implementation convention implies returning the number of bytes written. Adopt this last convention to be in line with what Apple's libc does. POSIX also explicitly notes: Note that this implementation convention cannot be adhered to for strings longer than {INT_MAX} bytes as the value would not be representable in the return type of the function. For backwards-compatibility, implementations can return the number of bytes for strings of up to {INT_MAX} bytes, and return {INT_MAX} for all longer strings. Developers shouldn't depend specifically on either convention but the change may help port software from Apple.

| | | | | | | | | | | | | | | | | | | | | | | | | do not participate in the global symbols namespace, but rtld locks are still replaced and functions are interposed. In particular, __pthread_map_stacks_exec is resolved to the libc version. If a library is loaded later, which requires adjustment of the stack protection mode, rtld calls into libc __pthread_map_stacks_exec due to the symbols scope. The libc version might recurse into binder and recursively acquire rtld bind lock, causing the hang. Make libc __pthread_map_stacks_exec() interposed, which synchronizes rtld locks and version of the stack exec hook when libthr loaded, regardless of the symbol scope control or symbol resolution order. The __pthread_map_stacks_exec() symbol is removed from the private version in libthr since libc symbol now operates correctly in presence of libthr.

| | | | | | | | | | | | | | | | | | | | | | time ago, but for some reason it was not. Basically, without this change dlopen(3)'ing an empty .so file would just cause application to dump core with SIGSEGV. Make sure the file has enough data for at least the ELF header before mmap'ing it. Add a test case to check that dlopen an empty file return an error. There were a separate discussion as to whether it should be SIGBUS instead when you try to access region mapped from an empty file, but it's definitely SIGSEGV now, so if anyone want to check that please be my guest.

| | | | | | | | | | | | | | | | | | | | | wraps sendmsg(2) and recvmsg(2) into batch send and receive operation. The goal of this implementation is only to provide API compatibility with Linux. The cancellation behaviour of the functions is not quite right, but due to relative rare use of cancellation it is considered acceptable comparing with the complexity of the correct implementation. If functions are reimplemented as syscalls, the fix would come almost trivial. The direct use of the syscall trampolines instead of libc wrappers for sendmsg(2) and recvmsg(2) is to avoid data loss on cancellation.

| | | | | | | | | | | | | | | | | | | | | | | Summary: Migrate to using the semi-opaque type rman_res_t to specify rman resources. For now, this is still compatible with u_long. This is step one in migrating rman to use uintmax_t for resources instead of u_long. Going forward, this could feasibly be used to specify architecture-specific definitions of resource ranges, rather than baking a specific integer type into the API. This change has been broken out to facilitate MFC'ing drivers back to 10 without breaking ABI.

* Add support to libsysdecode for decoding system call names.John Baldwin2016-01-265-2/+217
| | | | | | | | | | | | | | | | | | | | | | | | | | | A new sysdecode_syscallname() function accepts a system call code and returns a string of the corresponding name (or NULL if the code is unknown). To support different process ABIs, the new function accepts a value from a new sysdecode_abi enum as its first argument to select the ABI in use. Current ABIs supported include FREEBSD (native binaries), FREEBSD32, LINUX, LINUX32, and CLOUDABI64. Note that not all ABIs are supported by all platforms. In general, a given ABI is only supported if a platform can execute binaries for that ABI. To simplify the implementation, libsysdecode's build reuses the existing pre-generated files from the kernel source tree rather than duplicating new copies of said files during the build. kdump(1) and truss(1) now use these functions to map system call identifiers to names. For kdump(1), a new 'syscallname()' function consolidates duplicated code from ktrsyscall() and ktrsyscallret(). The Linux ABI no longer requires custom handling for ktrsyscall() and linux_ktrsyscall() has been removed as a result.

* Restore flushing of output for revoke(2) again. Document revoke()'sKonstantin Belousov2016-01-261-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | intended behaviour in its man page. Simplify tty_drain() to match. Don't call ttydevsw methods in tty_flush() if the device is gone since we now sometimes call it then. The flushing was supposed to be implemented by passing the FNONBLOCK flag to VOP_CLOSE() for revoke(). The tty driver is one of the few that can block in close and was one of the fewer that knew about this. This almost worked in FreeBSD-1 and similarly in Net/2. These versions only almost worked because there was and is considerable confusion between IO_NDELAY and FNONBLOCK (aka O_NONBLOCK). IO_NDELAY is only valid for VOP_READ() and VOP_WRITE(). For other VOPs it has the same value as O_SHLOCK. But since vfs_subr.c and tty.c consistently used the wrong flag and the O_SHLOCK flag is rarely set, this mostly worked. It also gave the feature than applications could get the non-blocking close by abusing O_SHLOCK. This was first broken then fixed in 1995. I changed only the tty driver to use FNONBLOCK, as a hack to get non-blocking via the normal flag FNONBLOCK for last closes. I didn't know about revoke()'s use of IO_NDELAY or change it to be consistent, so revoke() was broken. Then I changed revoke() to match. This was next broken in 1997 then fixed in 1998. Importing Lite2 made the flags inconsistent again by undoing the fix only in vfs_subr.c. This was next broken in 2008 by replacing everything in tty.c and not checking any flags in last close. Other bugs in draining limited the resulting unbounded waits to drain in some cases. It is now possible to fix this better using the new FREVOKE flag. Just restore flushing for revoke() for now. Don't restore or undo any hacks for ordinary last closes yet. But remove dead code in the 1-second relative timeout (r272789). This did extra work to extend the buggy draining for revoke() for as long as possible. The 1-second timeout made this not very long by usually flushing after 1 second.
