* Add a resource limit for the total number of kqueues available to thekib2013-10-211-5/+11
| | | | | | | | | | | | | | | | | | user. Kqueue now saves the ucred of the allocating thread, to correctly decrement the counter on close. Under some specific and not real-world use scenario for kqueue, it is possible for the kqueues to consume memory proportional to the square of the number of the filedescriptors available to the process. Limit allows administrator to prevent the abuse. This is kernel-mode side of the change, with the user-mode enabling commit following.

* Add support for RLIMIT_NPTS to limits(1).ed2008-09-022-54/+68
| | | | | | | | | | | | | After the MPSAFE TTY import we support an additional rlimit, called RLIMIT_NPTS. This limit allows you to cap the amount of pseudo-terminals allocated by one user. We forgot to add support for this limit to limits(1), which means it crashed. Add the proper bits to make it work like it should. Unfortunately not all shells actually implement the RLIMIT, so unfortunately I suspect it to be broken with certain shells. Submitted by: Yuriy Tsibizov <yuriy tsibizov gfk ru>
* Significantly reduce the memory leak as noted in BUGS section forscf2007-07-041-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | setenv(3) by tracking the size of the memory allocated instead of using strlen() on the current value. Convert all calls to POSIX from historic BSD API: - unsetenv returns an int. - putenv takes a char * instead of const char *. - putenv no longer makes a copy of the input string. - errno is set appropriately for POSIX. Exceptions involve bad environ variable and internal initialization code. These both set errno to EFAULT. Several patches to base utilities to handle the POSIX changes from Andrey Chernov's previous commit. A few I re-wrote to use setenv() instead of putenv(). New regression module for tools/regression/environ to test these functions. It also can be used to test the performance. Bump __FreeBSD_version to 700050 due to API change.

* Back out all POSIXified *env() changes.ache2007-05-011-2/+2
| | | | | | | | | Not because I admit they are technically wrong and not because of bug reports (I receive nothing). But because I surprisingly meets so strong opposition and resistance so lost any desire to continue that. Anyone who interested in POSIX can dig out what changes and how through cvs diffs.
