| | | | | | | | | | | | | | | | | | | | | | | | | Small cleanups to openpty(). - Pass O_NOCTTY to posix_openpt(2). This makes the implementation work consistently on implementations that make the PTY the controlling TTY by default. - Call unlockpt() before opening the slave device. POSIX mentions that de slave device should only be opened after grantpt() and unlockpt() have been called. - Replace some redundant code by a label. As a safety net, add a call to revoke() to unlockpt(). All applications out there use openpty(), explicitly call revoke() or implement their own PTY allocation routines. Adding the call to unlockpt() won't hurt, but will prevent foot-shooting. Reviewed by: jhb, kib Approved by: re Notes: svn path=/stable/7/; revision=184300

| | | | | | | | | | | | | The libc acl_valid(3) function validates the contents of a POSIX.1e ACL. This change removes the requirement that an ACL contain no ACL_USER entries with a uid the same as those of a file, or ACL_GROUP entries with a gid the same as those of a file. This requirement is not in the specification, and not enforced by the kernel's ACL implementation. Reported by: Iustin Pop <iusty at k1024 dot org> Notes: svn path=/stable/7/; revision=182534

| | | | | | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | and assignment. 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

| | | | | | | | | | | | | | | | | scandir(3) previously used st_size to obtain an initial estimate of the array length needed to store all the directory entries. Although BSD has historically guaranteed that st_size is the size of the directory file, POSIX does not, and more to the point, some recent filesystems such as ZFS use st_size to mean something else. The fix is to not stat the directory at all, set the initial array size to 32 entries, and realloc it in powers of 2 if that proves insufficient.
