Merge r303263:

2016-08-02T13:57:20Z

Partially revert r257696/r257713, which have an issue with writing to user controlled address. Restore the old code that emulated OSIOCGIFCONF in if.c. Approved by: re (kib)

MFC r302517:

2016-07-18T16:38:06Z

Fix a copy/paste bug introduced during X86_64 Linuxulator work. FreeBSD support NX bit on X86_64 processors out of the box, for i386 emulation use READ_IMPLIES_EXEC flag, introduced in r302515. While here move common part of mmap() and mprotect() code to the files in compat/linux to reduce code dupcliation between Linuxulator's Approved by: re (gjb)

MFC r302515:

Implement Linux personality() system call mainly due to READ_IMPLIES_EXEC flag. In Linux if this flag is set, PROT_READ implies PROT_EXEC for mmap(). Linux/i386 set this flag automatically if the binary requires executable stack. READ_IMPLIES_EXEC flag will be used in the next Linux mmap() commit. Approved by: re (gjb)

Fix a bug introduced in r283433.

[1] Remove unneeded sockaddr conversion before kern_recvit() call as the from argument is used to record result (the source address of the received message) only. [2] In Linux the type of msg_namelen member of struct msghdr is signed but native msg_namelen has a unsigned type (socklen_t). So use the proper storage to fetch fromlen from userspace and than check the user supplied value and return EINVAL if it is less than 0 as a Linux do.

Mark the pipe() system call as COMPAT10. As of r302092 libc uses pipe2() with a zero flags value instead of pipe(). Approved by: re (gjb) Sponsored by: DARPA, AFRL Differential Revision: https://reviews.freebsd.org/D6816
