mincore() is a relic from the past, exposing physical machine information

about shared resources which no program should see. only a few pieces of software use it, generally poorly thought out. they are being fixed, so mincore() can be deleted. ok guenther tedu jca sthen, others

Wrap and so that internal calls go direct

port the RBT code to userland by making it part of libc.

src/lib/libc/gen/tree.c is a copy of src/sys/kern/subr_tree.c, but with annotations for symbol visibility. changes to one should be reflected in the other. the malloc debug code that uses RB code is ported to RBT. because libc provides the RBT code, procmap doesn't have to reach into the kernel and build subr_tree.c itself now. mild enthusiasm from many ok guenther@

Use a Thread Information Block in both single and multi-threaded programs.

This stores errno, the cancelation flags, and related bits for each thread and is allocated by ld.so or libc.a. This is an ABI break from 5.9-stable! Make libpthread dlopen'able by moving the cancelation wrappers into libc and doing locking and fork/errno handling via callbacks that libpthread registers when it first initializes. 'errno' *must* be declared via now! Clean up libpthread's symbol exports like libc. On powerpc, offset the TIB/TCB/TLS data from the register per the ELF spec. Testing by various, particularly sthen@ and patrick@ ok kettenis@

Turd polish: use HIDDEN= instead of PSEUDO= for ptrace syscall stub, to

make its underlying symbol name look like others.

Wrap waitpid() so calls go direct; weaken wait() and wait3().

2015-10-25T19:15:56Z

Strip out unnecessary #includes and use NULL instead of (struct rusage *)0

recv() and send() aren't overriden by libpthread (vs recvfrom() and sendto()!)

2015-10-04T07:17:27Z

so wrap them to make internal calls go direct

getpeereid() and sockatmark() are neither used in libc nor in ISO C, so mark

2015-10-04T07:14:48Z

them deprecated and weak

Wrap so internal calls go direct and all the symbols are weak

2015-09-14T12:08:49Z

Make isfdtype() and getmntinfo() weak symbols
