* The getlogin_basic() function can return a 0 status with a NULLmarcel2014-04-051-3/+8
| | | | | | | | | pointer for the login name (result). Make sure to handle that case properly. Improve robustness by checking namelen and then nul-terminating the provided buffer to simplify subsequent logic. Obtained from: Juniper Networks, Inc. MFC after: 1 week
* libc: Access _logname_valid more efficiently.jilles2013-08-171-1/+1
| | | | | | | | | | | The variable _logname_valid is not exported via the version script; therefore, change C and i386/amd64 assembler code to remove indirection (which allowed interposition). This makes the code slightly smaller and faster. Also, remove #define PIC_GOT from i386/amd64 in !PIC mode. Without PIC, there is no place containing the address of each variable, so there is no possible definition for PIC_GOT.
* Don't let the C library depend on <utmp.h>.ed2009-12-051-1/+0
| | | | | | The maximum length of a username has nothing to do with the size of the username in the utmp files. Use MAXLOGNAME, which is defined as 17 (UT_USERSIZE + 1).

* Do not use __progname directly (except in [gs]etprogname(3)).markm2002-03-291-1/+1
| | | | | | Also, make an internal _getprogname() that is used only inside libc. For libc, getprogname(3) is a weak symbol in case a function of the same name is defined in userland.

* Remove _THREAD_SAFE and make libc thread-safe by default bydeischen2001-01-241-13/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | adding (weak definitions to) stubs for some of the pthread functions. If the threads library is linked in, the real pthread functions will pulled in. Use the following convention for system calls wrapped by the threads library: __sys_foo - actual system call _foo - weak definition to __sys_foo foo - weak definition to __sys_foo Change all libc uses of system calls wrapped by the threads library from foo to _foo. In order to define the prototypes for _foo(), we introduce namespace.h and un-namespace.h (suggested by bde). All files that need to reference these system calls, should include namespace.h before any standard includes, then include un-namespace.h after the standard includes and before any local includes. <db.h> is an exception and shouldn't be included in between namespace.h and un-namespace.h namespace.h will define foo to _foo, and un-namespace.h will undefine foo. Try to eliminate some of the recursive calls to MT-safe functions in libc/stdio in preparation for adding a mutex to FILE. We have recursive mutexes, but would like to avoid using them if possible. Remove uneeded includes of <errno.h> from a few files. Add $FreeBSD$ to a few files in order to pass commitprep. Approved by: -arch
* Change the interface of getlogin_r to return an int. The formerdeischen2001-01-011-17/+50
| | | | | | | | | | interface was based on a draft version of POSIX whereas the final (1996) version of POSIX specified that the error is returned. While I'm here, fix getlogin_r so that it works for more than just the first time it's called. Reviewed by: wes, wollman (man page)
