* libc: indicate existing functions that are POSIX 2024Ed Maste2024-11-211-1/+2

* Add GNU glibc compatible secure_getenvlucy2023-03-141-1/+25
| | | | | | | | | | | | Add mostly glibc and msl compatible secure_getenv. Return NULL if issetugid() indicates the process is tainted, otherwise getenv(x). The rational behind this is the fact that many Linux applications use this function instead of getenv() as it's widely consider a, "best practice".

* libc: add clearenv functionMariusz Zaborski2021-11-071-2/+18
| | | | | | | | | | The clearenv(3) function allows us to clear all environment variable in one shot. This may be useful for security programs that want to control the environment or what variables are passed to new spawned programs.

* Significantly reduce the memory leak as noted in BUGS section forSean Farley2007-07-041-24/+80
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.Andrey A. Chernov2007-05-011-35/+18
| | | | | | | | | | | | 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.

* Make putenv() fully conforms to Open Group specs Issue 6Andrey A. Chernov2007-04-301-6/+13
| | | | | | | | | | | | | | (also IEEE Std 1003.1-2001) The specs explicitly says that altering passed string should change the environment, i.e. putenv() directly puts its arg into environment (unlike setenv() which just copies it there). It means that putenv() can't be implemented via setenv() (like we have before) at all. Putenv() value lives (allows modifying) up to the next putenv() or setenv() call.

| | | | | | | | | | | | compatibility with the different environment conventions" (man page). With the standards, we don't have them different anymore and IEEE Std 1003.1-2001 says that "The values that the environment variables may be assigned are not restricted except that they are considered to end with a null byte" Notes: svn path=/head/; revision=169111
* Make setenv, putenv, getenv and unsetenv conforming to Open Group specsAndrey A. Chernov2007-04-301-9/+23
| | | | | | | | | | | | Issue 6 (also IEEE Std 1003.1-2001) in following areas: args, return, errors. Putenv still needs rewriting because specs explicitly says that altering passed string later should change the environment (currently we copy the string so can't provide that).
