2024-02-18Avoid fall-through if file matching temporary name existsSven Linker
During checking whether a temporary name can be created, it may happen that a file with this name already exists. Avoid falling through to opening the file name in this case, and return with an error instead. Signed-off-by: Sven Linker <sven.linker@kernkonzept.com>

Fixes this: libc/misc/internals/tempname.c: In function 'brain_damaged_fillrand': libc/misc/internals/tempname.c:155:0: warning: "L" redefined #define L ((UINT32_MAX % NUM_LETTERS + 1) % NUM_LETTERS) In file included from ./libpthread/nptl/sysdeps/unix/sysv/linux/lowlevellock.h:24:0, from ./include/bits/libc-lock.h:35, from ./include/bits/stdio-lock.h:22, from ./include/bits/uClibc_mutex.h:73, from ./include/bits/uClibc_stdio.h:83, from ./include/stdio.h:71, from libc/misc/internals/tempname.c:35: ./libc/sysdeps/linux/kvx/sysdep.h:40:0: note: this is the location of the previous definition # define L(name) $L##name Signed-off-by: Yann Sionneau <ysionneau@kalray.eu>

Change __gen_tempname() prototype in order to pass the additional suffix lenght. In __gen_tempname() add a new check for suffixlen. Update some comments in the code. Signed-off-by: Romain Naour <romain.naour@openwide.fr> Signed-off-by: Waldemar Brodkorb <wbx@uclibc-ng.org>
2014-12-10mkostemp: fix implementationAnthony G. Basile
mkostemp(char *template, int flags) generates a unique temporary filename from a template. The flags parameter accepts three of the same flags as open(2): O_APPEND, O_CLOEXEC, and O_SYNC. The current implementation of mkostemp(3) does not respect the flags and in fact confuses the flags with the file mode which should always be S_IRUSR | S_IWUSR. This patch corrects this issue.

2011-02-22tempname: fix int precision warningsMike Frysinger
The printf precision takes an integer, not a size_t. Otherwise we get: libc/misc/internals/tempname.c: In function '___path_search': libc/misc/internals/tempname.c:116: warning: field precision should have type 'int', but argument 3 has type 'size_t' field precision should have type 'int', but argument 5 has type 'size_t' Signed-off-by: Mike Frysinger <vapier@gentoo.org>

__gen_tempname now needs to not be hidden so libpthread can get at it Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
2009-11-09Extend __gen_tempname with mode argumentMikhail Gusarov
sem_open(3) needs to create a temporary file in a way which can't be efficiently implemented in terms of POSIX API. Extend __gen_tempname with mode_t mode argument in order to ease sem_open implementation. Signed-off-by: Mikhail Gusarov <dottedmag@dottedmag.net> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>

in string.h and strings.h. This caught unguarded string ops in libc/inet/ethers.c __ether_line_w() function. I will wait for fallout reports for a week or so, then continue converting more libc_hidden_proto's.

2005-04-16In Bug 116, dicksnippe writes:Mike Frysinger
uClibc's mkstemp/mktemp tries to read /dev/urandom (or /dev/random) to generate random contents for the .XXXXXX part of its argument. In a chrooted environment /dev/[u]random might not be available. Thus the mkstemp call fails. Add back in the braindamaged gettimeofday/getpid code, but only as a fallback for when reading /dev/[u]random fail for whatever reasons.

2002-10-31Ok, this commit is _huge_ and its gonna change the world. I'veEric Andersen
been working on a new config system on and off for about 6 months now, but I've never been fully satisfied. Well, I'm finally am happy with the new config system, so here it is. This completely removes the old uClibc configuration system, and replaces it with an entirely new system based on LinuxKernelConf, from http://www.xs4all.nl/~zippel/lc/ As it turns out, Linus has just merged LinuxKernelConf into Linux 2.5.45, so it looks like I made the right choice. I have thus far updated only x86. I'll be updating the other architectures shortly. -Erik
