- getaddrinfo(3) should accept numeric when ai_socktype is not specified in hint or hints is NULL. - Add support for SCTP to getaddrinfo(3). Now, getaddrinfo(3) returns two SOCK_STREAMs, IPPROTO_TCP and IPPROTO_SCTP. It confuses some programs. If getaddrinfo(3) returns IPPROTO_SCTP when SOCK_STREAM is specified by hints.ai_socktype, at least Apache doesn't work. So, I made getaddrinfo(3) to return IPPROTO_SCTP with SOCK_STREAM only when IPPROTO_SCTP is specified explicitly by hints.ai_protocol. - Query DNS only once per an address family.

7.2 will be the first release where strndup() appears. Approved by: re (kensmith)

Mostly synchronize lib/libthr and sys/kern/kern_umtx.c with the code

from HEAD. Since libkse is still built on RELENG_7, pthread_cleanup_push/pop are left as the functions, but the support code in libthr is present for the macro versions. Malloc in RELENG_7 does not require thread exit hook, but I decided to add empty handler for it, instead of removing callback from thr_exit(). No mergeinfo since this change is prepared by patching libthr and then bringing in required missed bits.

Correct types of variables used to track amount of allocated SysV shared memory from int to size_t. Implement a workaround for current ABI not allowing to properly save size for and report more then 2GB sized segment of shared memory. This makes it possible to use > 2 GB shared memory segments on 64bit architectures. Please note the new BUGS section in shmctl(2) and UPDATING note for limitations of this temporal solution. MFC r189398: Systematically use vm_size_t to specify the size of the segment for VM KPI. Do not overload the local variable size in kern_shmat() due to vm_size_t change. Fix style bug by adding explicit comparision with 0. MFC r189399: Improve the grammar and wording in the changes to shmctl(2) manpage. Put an UPDATING entry and bump __FreeBSD_version for the change.

r188144: Standardize the various prison_foo_ip[46] functions and prison_if to return zero on success and an error code otherwise. The possible errors are EADDRNOTAVAIL if an address being checked for doesn't match the prison, and EAFNOSUPPORT if the prison doesn't have any addresses in that address family. For most callers of these functions, use the returned error code instead of e.g. a hard-coded EADDRNOTAVAIL or EINVAL. Always include a jailed() check in these functions, where a non-jailed cred always returns success (and makes no changes). Remove the explicit jailed() checks that preceded many of the function calls. r188146: Don't allow creating a socket with a protocol family that the current jail doesn't support. This involves a new function prison_check_af, like prison_check_ip[46] but that checks only the family. With this change, most of the errors generated by jailed sockets shouldn't ever occur, at least until jails are changeable. r188148: Remove redundant calls of prison_local_ip4 in in_pcbbind_setup, and of prison_local_ip6 in in6_pcbbind. r188149: Call prison_if from rtm_get_jailed, instead of splitting it out into prison_check_ip4 and prison_check_ip6. As prison_if includes a jailed() check, remove that check before calling rtm_get_jailed. r188151: Don't bother null-checking the thread pointer before the prison checks in udp6_connect (td is already dereferenced elsewhere without such a check). This makes the conversion from a sockaddr to a sockaddr_in6 always happen, so convert once at the beginning of the function rather than twice in the middle. Approved by: bz (mentor)
