* MFC: Change the ABI of some of the structures used by the SYSV IPC API:John Baldwin2009-07-314-21/+9
| | | | | | | | | | | | | | | | | | | | | - Various members of struct ipc_perm use appropriate types instead of unsigned short. - The shm_segsz member of struct shmid_ds is now a size_t instead of an int which should allow for complete support of SYSV SHM regions >= 2GB. - The shm_nattch member of struct shmid_ds is now an int instead of a short. - The existing versions of the __semctl(), msgctl(), and shmctl() system calls have been renamed to freebsd7_*() and implement the old ABI. New versions of these system calls provide the new ABI. The new system calls also use newer symbol versions in libc so old and new binaries will both work under new kernels. - Specific to 7.x: the kern_msgctl(), kern_semctl(), and kern_shmctl() functions now use ABI shims that transparently "rename" the functions to kern_new_*() for all new modules. Existing compat functions under the old names remain to provide compatibility for older kernel modules. Notes: svn path=/stable/7/; revision=196006
* MFC r194494 to improve support for 7.x worlds on >=8.0 kernels:Brooks Davis2009-07-242-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | In preparation for raising NGROUPS and NGROUPS_MAX, change base system callers of getgroups(), getgrouplist(), and setgroups() to allocate buffers dynamically. Specifically, allocate a buffer of size sysconf(_SC_NGROUPS_MAX)+1 (+2 in a few cases to allow for overflow). This (or similar gymnastics) is required for the code to actually follow the POSIX.1-2008 specification where {NGROUPS_MAX} may differ at runtime and where getgroups may return {NGROUPS_MAX}+1 results on systems like FreeBSD which include the primary group. In id(1), don't pointlessly add the primary group to the list of all groups, it is always the first result from getgroups(). In principle the old code was more portable, but this was only done in one of the two places where getgroups() was called to the overall effect was pointless. Document the actual POSIX requirements in the getgroups(2) and setgroups(2) manpages. We do not yet support a dynamic NGROUPS, but we may in the future. Notes: svn path=/stable/7/; revision=195859
* MFC: Several cleanups to the syscall tables:John Baldwin2009-07-241-3/+0
| | | | | | | | | | | | | | | | | | | | | | - Add explicit prototypes for lkmnosys() and lkmressys() in <sys/sysent.h> and remove hacks for those routines from makesyscalls.sh. - Change the LKM syscall entries in the freebsd32 table to use lkmnosys rather than nosys. - Use NOPROTO for __syscall() to remove more magic logic from makesyscalls.sh. - Retire the unused nfsclnt() system call and mark it as UNIMPL rather than NOIMPL. - Remove the NOIMPL system call type. - Allow multiple flags in the type system call type field. Use this to retire CPT_NOA. - Update the comment descriptions for COMPAT[45] system calls in various generated files. - Update comments in syscalls.master. - Include defintions for audit identifiers for compat system calls in <sys/sysproto.h>.

Implement a workaround for current ABI not allowing to properly save size for and report more then 2GB sized segment of shared memory.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Bump __FreeBSD_version for the afore mentioned and in kernel changes. r185441: Unbreak the no-networks (no INET/6) build. r185899: Correctly check the number of prison states to not access anything outside the prison_states array.

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. Note that, just as in HEAD, cpusets currently don't work on SCHED_4BSD (the syscalls will succeed, but they don't have any effect). Tested by: brooks, ps Notes: svn path=/stable/7/; revision=180808
