| | | | | | | | | | | | | | | | | | - 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.

| | | | | | | | | | | | | | | | | | | | | | 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.

In addtion to IPv4, IPv6 is supported as well. Due to updated checks it is even possible to have jails without an IP address at all, which basically gives one a chroot with restricted process view, no networking,.. SCTP support was updated and supports IPv6 in jails as well. Cpuset support permits jails to be bound to specific processor sets after creation. Jails can have an unrestricted (no duplicate protection, etc.) name in addition to the hostname. The jail name cannot be changed from within a jail and is considered to be used for management purposes or as audit-token in the future. DDB 'show jails' command was added to aid debugging. Proper compat support permits 32bit jail binaries to be used on 64bit systems to manage jails. Also backward compatibility was preserved where possible: for jail v1 syscalls, as well as with user space management utilities. Both jail as well as prison version were updated for the new features. A gap was intentionally left as the intermediate versions had been used by various patches floating around the last years.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Detect if the application has cleared the environ variable by setting the first value (environ[0]) to NULL. This is in addition to the current detection of environ being replaced, which includes being set to NULL. Without this fix, the environment is not truly wiped, but appears to be by getenv() until an *env() call is made to alter the enviroment. This change is necessary to support those applications that use this method for clearing environ such as Dovecot and Postfix. Applications such as Sendmail and the base system's env replace environ (already detected). While neither of these methods are defined by SUSv3, it is best to support them due to historic reasons and in lieu of a clean, defined method. Add extra units tests for clearing environ using four different methods: 1. Set environ to NULL pointer. 2. Set environ[0] to NULL pointer. 3. Set environ to calloc()'d NULL-terminated array. 4. Set environ to static NULL-terminated array. Noticed by: Timo Sirainen Reviewed by: ache Notes: svn path=/stable/7/; revision=181407

This is mostly synched up with what is in HEAD with the following exceptions: - I didn't MFC any of the interrupt binding stuff as it requires other changes and I figured this change was large enough as it is. - The sched_affinity() implementation for ULE in HEAD depends on the newer CPU topology stuff as well as other changes in ULE. Rather than backport all of that, I implemented sched_affinity() using the existing CPU topology and ULE code in 7.x. Thus, any bugs in the ULE affinity stuff in 7 are purely my fault and not Jeff's.
