Fix a problem whereby a corrupt DNS record can cause named to crash. [11:06]

Add an API for alerting internal libc routines to the presence of "unsafe" paths post-chroot, and use it in ftpd. [11:07] Fix a buffer overflow in telnetd. [11:08] Make pam_ssh ignore unpassphrased keys unless the "nullok" option is specified. [11:09] Add sanity checking of service names in pam_start.

Add getpagesizes(3) function that returns either the number of page sizes supported by the system or a specified subset of the supported page sizes. Approved by: re (kib)

MFC: Change the ABI of some of the structures used by the SYSV IPC API:

2009-07-31T20:32:55Z

- 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.

MFC: Add a feature_present(3) function which checks to see if a named kernel

feature is present by checking the kern.features sysctl MIB.

Implement fdopendir(3) by splitting __opendir2() into two parts, the upper part deals with the usual __opendir2() calls, and the rest part with an interface translator to expose fdopendir(3) functionality. Manual page was obtained from kib@'s work for *at(2) system calls.

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

2009-03-24T20:57:10Z

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.

MFC: Merge malloc(3) improvements and fixes. The highlights are:

2008-03-07T22:39:39Z
* Avoid re-zeroing memory in calloc() when possible. * Use pthread mutexes where possible instead of libc "spinlocks", and actually spin some during contention before blocking. * Implement dynamic load balancing of thread-->arena mapping. * Avoid floating point math in order to avoid increased context switch overhead for applications that otherwise would not use floating point math. * Restructure how sbrk() and mmap() are used to acquire memory mappings. This provides a way to force malloc to only use sbrk(), which can be useful in the context of resource limits. * Reduce the number of mmap() calls typically necessary when allocating a chunk. * Track dirty unused pages so that they can be purged if they exceed a threshold. * Try to realloc() large objects in place. * Manage page runs with trees instead of chunk maps, which allows logarithmic-time run allocation.

Some libc symbol map cleanups.

net: endhostdnsent is named _endhostdnsent and is private to netdb family of functions. posix1e: acl_size.c has been never compiled in, so there's no "acl_size". rpc: "getnetid" is a static function. stdtime: "gtime" is #ifdef'ed out in the source. some symbols are specific only to some architectures, e.g., ___tls_get_addr is only defined on i386. __htonl, __htons, __ntohl and __ntohs are no longer functions, they are now (internal) defines in .
